 BUSINESS

 NBT Bancorp Inc. is a registered financial holding company incorporated in the state of Delaware in 1986, with its principal headquarters located in Norwich, New York. The principal assets of NBT Bancorp Inc. consist of all of the outstanding
 shares of common stock of its subsidiaries, including: NBT Bank, National Association (the "Bank"), NBT Financial Services, Inc. ("NBT Financial"), NBT Holdings, Inc. ("NBT Holdings"), CNBF Capital Trust I, NBT Statutory Trust I, NBT Statutory
 Trust II, Alliance Financial Capital Trust I and Alliance Financial Capital Trust II (collectively, the "Trusts"). The principal sources of revenue for NBT Bancorp Inc. are the management fees and dividends it receives from the Bank, NBT Financial
 and NBT Holdings. Collectively, NBT Bancorp Inc. and its subsidiaries are referred to herein as (the "Company"). The Company, on a consolidated basis, at December 31, 2023 had assets of $13.31 billion and stockholders' equity of $1.43 billion. When
 we refer to "NBT," "we," "our," "us," and "the Company" in this report, we mean NBT Bancorp Inc. and our consolidated subsidiaries, unless the context indicates that we refer only to the parent company, NBT Bancorp Inc. When we refer to the "Bank"
 in this report, we mean its only bank subsidiary, NBT Bank, National Association, and its subsidiaries.

 The Company's business, primarily conducted through the Bank, consists of providing commercial banking, retail banking and wealth management services primarily to customers in its market area,
 which includes upstate New York, northeastern Pennsylvania, southern New Hampshire, western Massachusetts, Vermont, southern Maine and central and northwestern Connecticut. The Company has been, and intends to continue to be, a community-oriented
 financial institution offering a variety of financial services. The Company's business philosophy is to operate as a community bank with local decision-making, providing a broad array of banking and financial services to retail, commercial and
 municipal customers. The financial condition and operating results of the Company are dependent on its net interest income, which is the difference between the interest and dividend income earned on its earning assets, primarily loans and
 investments and the interest expense paid on its interest-bearing liabilities, primarily consisting of deposits and borrowings. Among other factors, net income is also affected by provisions for loan losses and noninterest income, such as service
 charges on deposit accounts, card services income, retirement plan administration fees, wealth management revenue including financial services and trust revenue, insurance services, bank owned life insurance income and gains/losses on securities
 sales, as well as noninterest expenses, such as salaries and employee benefits, technology and data services, occupancy, professional fees and outside services, office supplies and postage, amortization of intangible assets, loan collection and
 other real estate owned ("OREO") expenses, advertising, Federal Deposit Insurance Corporation ("FDIC") assessment expenses and other expenses.

 NBT Bank, N.A.

 branch network, the Bank also offers access to certain products and services electronically through 24-hour online, mobile and telephone channels that enable customers to check balances, make deposits, transfer funds, pay bills, access statements,
 apply for loans and access various other products and services.

 Table

 The Trusts

 The Trusts were organized to raise additional regulatory capital and to provide funding for certain acquisitions. CNBF Capital Trust I and NBT Statutory Trust I are Delaware statutory business
 trusts formed in 1999 and 2005, respectively, for the purpose of issuing trust preferred securities and lending the proceeds to the Company. In connection with the acquisition of CNB Bancorp, Inc., the Company formed NBT Statutory Trust II in
 February 2006 to fund the cash portion of the acquisition as well as to provide regulatory capital. In connection with the acquisition of Alliance Financial Corporation ("Alliance"), the Company acquired two statutory trusts, Alliance Financial
 Capital Trust I and Alliance Financial Capital Trust II, which were formed in 2003 and 2006, respectively. The Company guarantees, on a limited basis, payments of distributions on the trust preferred securities and payments on redemption of the
 trust preferred securities. The Trusts are variable interest entities for which the Company is not the primary beneficiary, as defined by Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC"). In accordance with
 ASC, the accounts of the Trusts are not included in the Company's consolidated financial statements.

 Operating Subsidiaries of the Bank

 The Bank has four operating subsidiaries, NBT Capital Corp., Broad Street Property Associates, Inc., NBT Capital Management, Inc. and SBT Mortgage Service Corporation. NBT Capital Corp., formed
 in 1998, is a venture capital corporation. Broad Street Property Associates, Inc., formed in 2004, is a property management company. NBT Capital Management, Inc., formerly Columbia Ridge Capital Management, Inc., was acquired in 2016 and is a
 registered investment advisor that provides investment management and financial consulting services. SBT Mortgage Service Corporation is a passive investment company ("PIC") acquired in 2023 in connection with the acquisition of Salisbury Bancorp,
 Inc. ("Salisbury"). The PIC holds loans collateralized by real estate originated or purchased by the Bank. Income of the PIC is exempt from the Connecticut Corporate Business Tax.

 Merger with Salisbury Bancorp, Inc.

 On August 11, 2023, the Company completed the acquisition of Salisbury through the merger of Salisbury with and into the Company, with the Company surviving the merger, and the merger of
 Salisbury Bank and Trust Company ("Salisbury Bank") with and into the Bank, with the Bank as the surviving bank, for $161.7 million in stock. Salisbury Bank was a Connecticut-chartered commercial bank headquartered in Lakeville, Connecticut with 13
 banking offices in northwestern Connecticut, the Hudson Valley region of New York, and southwestern Massachusetts. In connection with the acquisition, the Company issued 4.32 million shares and acquired approximately $1.46 billion of identifiable
 assets, including $1.18 billion of loans, $122.7 million in investment securities, which were sold immediately after the merger, $31.2 million of core deposit intangibles and $4.7 million in a wealth management customer intangible, as well as $1.31
 billion in deposits. As of the acquisition date, the fair value discount was $78.7 million for loans, net of the reclassification of the purchase credit deteriorated allowance, and was $3.0 million for subordinated debt.

 Competition

 The financial services industry, including commercial banking, is highly competitive, and we encounter strong competition for deposits, loans and other financial products and services in our
 market area. The increasingly competitive environment is the result of the rate environment, changes in regulation, changes in technology and product delivery systems, additional financial service providers and the accelerating pace of
 consolidation among financial services providers. The Company competes for loans, deposits and customers with other commercial banks, savings and loan associations, securities and brokerage companies, mortgage companies, insurance companies,
 finance companies, money market funds, credit unions and other nonbank financial service providers.

 The financial services industry could become even more competitive as a result of legislative, regulatory and technological changes and continued consolidation. Banks, securities firms and
 insurance companies can merge under the umbrella of a financial holding company, which can offer virtually any type of financial service, including banking, securities underwriting, insurance (both agency and underwriting) and merchant banking. In
 addition, technology has lowered barriers to entry and made it possible for non-banks to offer products and services traditionally provided by banks, such as automatic transfer and automatic payment systems.

 Some of the Company's nonbanking competitors have fewer regulatory constraints and may have lower cost structures. In addition, some of the Company's competitors have assets, capital and lending
 limits greater than that of the Company, have greater access to capital markets and offer a broader range of products and services than the Company. These institutions may have the ability to finance wide-ranging advertising campaigns and may be
 able to offer lower rates on loans and higher rates on deposits than the Company can offer. Some of these institutions offer services, such as credit cards and international banking, which the Company does not directly offer.

 Various in-state market competitors and out-of-state banks continue to enter or have announced plans to enter or expand their presence in the market areas where the Company currently operates.
 With the addition of new financial services providers within our market, the Company expects increased competition for loans, deposits and other financial products and services.

 Table

 In order to compete with other financial services providers, the Company stresses the community nature of its banking operations and principally relies upon local promotional activities, personal
 relationships established by officers, directors and employees with the Company's customers and specialized services tailored to meet the needs of the communities served. We also offer certain customer services, such as agricultural lending, that
 many of our larger competitors do not offer. While the Company's position varies by market, the Company's management believes that it can compete effectively as a result of local market knowledge, local decision making and awareness of customer
 needs. The Company has banking locations in forty-two counties in the states of New York, Pennsylvania, New Hampshire, Massachusetts, Vermont, Maine and Connecticut.

 Data Privacy and Security Practices

 The Company's enterprise security strategy revolves around people, processes and technology. The Company employs a defense in depth strategy, which combines physical control measures with logical
 control measures and uses a layered security model to provide end-to-end security of Company and client information. The high-level objective of the information security program is to protect the confidentiality, integrity and availability of all
 information assets in our environment. We accomplish this by building our program around six foundational control areas: program oversight and governance, safeguards and controls, security awareness training, service provider oversight, incident
 response and business continuity. The Company's data security and privacy practices follow all applicable laws and regulations including the Gramm-Leach Bliley Act of 2001 ("GLBA") and applicable privacy laws described under the heading
 "Supervision and Regulation" in this Item 1. Business section.

 The controls identified in our enterprise security program are managed by various stakeholders throughout the Company and monitored by the information security team. All employees are required to
 complete information security and privacy training when they join the Company and then complete annual online training certification and ad hoc face to face trainings. The Company engages outside consultants to perform periodic audits of our
 information and data security controls and processes including penetration testing of the Company's public facing websites and corporate networks. The Board of Directors of the Company (the "Board") requires the Company's Information Security
 Officer to report to them the status of the overall information security and data privacy program on a recurring basis. More information can be located on the Company's website

 For more information regarding the Company's cybersecurity policies and practices, see Item 1C. Cybersecurity below.

 Human Capital Resources

 Diversity, Equity and Inclusion

 The Company's diversity, equity and inclusion ("DEI") strategy aims to enhance diversity within our organization, making us more innovative and effective at meeting the needs of our customers and
 the communities we serve. The Company utilizes a variety of approaches to maximize diversity within each pool of candidates through both internal and external recruitment practices. It is the Company's belief that these efforts will provide
 equitable opportunities and contribute to improved products and services, better customer engagement and ultimately enhanced stockholder return.

 Both grassroots and executive sponsored strategies continue to be critical to our DEI initiatives. Executive sponsored strategies support leadership opportunities with cross functional/geographic
 teams and panel discussions for employees and our communities hosted by our affinity group NBT Empowerment in support of women's empowerment and being your authentic self. We have philanthropic goals to support our communities and, in 2023, we
 established a specific budget for DEI related contributions. We supported our communities with financial contributions for the first Pride festival in Chenango County, for a black baseball exhibit at the Cooperstown Baseball Hall of Fame and we
 made our second contribution in a five-year commitment supporting a LGBTQ+ youth community center in Maine. Our DEI Inclusion Roundtable supports grassroots efforts focusing on raising awareness of various cultural and diverse interests. NBT
 Communities is an internal social media forum where employees with similar interests across the footprint can connect and get to know each other around a variety of topics.

 The Company has a DEI steering committee comprised of members of the executive team, including the Chief Executive Officer. The plan is shared with the Board, management, and employees, who are
 often included in implementing specific action items.

 Investment in Our People

 The Company's focus on investing in our people includes key initiatives to attract, develop and retain our valued employees. Talent acquisition and more importantly, retention, continue to be top
 priorities especially in the post-pandemic environment and considering the current challenges in the labor market. An Employee Referral Program was implemented in the third quarter of 2022. In 2023, 84 qualified referrals were made by employees,
 equating to 28% of the total new employees hired. 88% of referred employees continue to be employed.

 Table

 The Company offers total rewards that address employees at various stages of their personal lives and careers, including financial wellness programs, undergraduate and graduate tuition, paid
 parental leave, more flexibility in work schedules and paid leave benefits and a retirement transition option. The Company's incentive programs recognize employees at all levels and are designed to motivate employees to support the achievement of
 company success, with appropriate risk assessment and prevention measures designed to prevent fraud.

 Engaging Employees

 While our employee retention rate remains consistently high, we continue to place significant effort toward retaining our valued employees - career planning conversations, an on-going coaching
 process, goal setting, individual development plans and enhanced communications all play a part in employee satisfaction. In the first quarter of 2024, we will administer our Employee Engagement Survey. The results from the survey will be used to
 define specific initiatives to enhance engagement around the organization including clarity with respect to our business strategies, decision making and corporate led development programs.

 Learning and Career Development

 The Company's main priority is to attract and retain top talent by encouraging and promoting internal development. All employees have access to the Linked In Learning Library, which is intended to
 make learning and development accessible in a concise, easily consumable format that enables employees to get the development they need to achieve individual career aspirations. Currently 80% of our employees are active in the learning library and
 are taking full advantage of this resource.

 In addition to the library, there are distinct training and development programs strategically designed to attract top talent early in their careers and to further foster the growth and retention
 of our high potential and emerging leaders. These programs have been designed to meet the objectives outlined in our succession plan. Our Management Development Program aims to attract diverse talent, primarily college seniors by offering
 accelerated career advancement and mentoring with senior executives. The Company also offers two programs designed for high potential employees, one for employees with prior professional experience and another one targeted to our more experienced
 employees with direct leadership responsibility. Both programs include a mentor, a coach, 360-degree feedback, individual development plans, presentation skill development and increased visibility to executive leadership. The programs accommodate
 delivery in both remote and in person learning environments, made possible by utilizing our Microsoft Teams technology which was implemented across the Company to strengthen internal communications, collaboration, and talent development. To support
 career development, we employ an internal career manager to work as a liaison with employees and managers. The Company also has a robust annual talent review and succession planning process that includes the Board and senior management.

 Conduct and Ethics

 The Board, senior management and the ethics committee have vigorously endorsed a no-tolerance stance for workplace harassment, biases and unethical behavior. The Company's values-based Code of
 Business Conduct and Ethics is extensively communicated on our website and targeted internal communications platforms. Frequent training specific to managers and employees, regular publication of our whistleblower policy and reporting mechanisms
 provide framework to the Company's motto of: "The right people. Doing the right things. In the right way."

 Community Engagement

 The Company is engaged in the communities where we do business and where our employees and directors live and work. We live out our core value of community involvement through investments of both
 money and the time of our employees.

 Through our active contribution program, administered by market-based committees with representation from all lines of business, the Company contributed over $2.0 million in 2023. Our teams'
 efforts to distribute philanthropic resources across our footprint ensure alignment with local needs and support for hundreds of organizations that provide health and human services and promote education, affordable housing, economic development,
 the arts and agriculture. The Company has pledged to maintain charitable support in the markets served by Salisbury Bank following the acquisition in August 2023 and to make an additional $500,000 in geographically focused contributions to
 demonstrate the ongoing commitment to these markets.

 A consistent way that the Company and our employees support our communities across our markets is through giving to United Way chapters in the form of corporate pledges and employee campaign
 contributions. In 2023, these commitments resulted in over $355,000 in funding for United Way chapters that provide resources to local organizations offering critical education, financial, food security and health services.

 In addition to corporate financial support of community organizations and causes, employees are encouraged and empowered to volunteer and be a resource in their communities. They invest their
 financial and other expertise as board members and serve in roles where they offer direct support to those in need by engaging in all manner of volunteer activities.

 The NBT CEI-Boulos Impact Fund, a high-impact commercial real estate equity investment fund established by the Bank and CEI-Boulos Capital Management, announced its first equity investment in
 2023 that will provide affordable, workforce housing and a grocery store for residents in Troy, NY. The Flanigan Square Transformation Project is an approximately $75 million socially impactful, environmentally conscious, transit-oriented and
 community informed master plan, located at the 500 block of River Street along the Hudson River waterfront in the historically underinvested North Central neighborhood of Troy. The NBT CEI-Boulos Impact Fund made a $3.84 million equity investment
 for a majority ownership stake in two of the three components of the project.

 The NBT CEI-Boulos Impact Fund, LLC launched in 2022 is a $10 million real estate equity investment fund with the Bank as the sole investor. The fund is designed to support individuals and
 communities with low- and moderate income through investments in high-impact, community supported, commercial real estate projects located within the Bank's Community Reinvestment Act assessment areas in New York. A Social Impact Advisory Board was
 also appointed to review proposed investments based on each project's social and environmental impact, alignment with community needs and community support. Areas of the fund's targeted impact include: projects that support job creation; affordable
 and workforce housing; Main Street revitalization/historic preservation developments that do not contribute to displacement; developments that serve nonprofit organizations; and environmentally sustainable real estate developments.

 Home in the City, Portfolio Housing Agency and Portfolio 97 programs. Our home lending team includes affordable housing loan originators, and we maintain longstanding relationships with affordable housing agency partners across our banking
 footprint that offer first-time homebuyer education programs and assistance with down payments and closing costs.

 Environmental

 The Company is focused on the environment and committed to business practices and activities that encourage sustainability and minimize our environmental impact. In larger facilities, the Company
 conserves energy through the use of building energy management systems and motion sensor lighting controls. In new construction and renovations, the Company incorporates high-efficiency mechanical equipment, LED lighting, and modern building
 techniques to reduce our carbon footprint wherever possible. The Company has an ongoing initiative to replace existing lighting with LED lighting to reduce energy consumption.

 The Company offers a financing product to homeowners on a national basis which provides an opportunity to power their homes with sustainable solar energy and reduce their carbon footprint at an
 affordable price. Services like mobile and online banking, remote deposit capture, electronic loan payments, eStatements and combined statements enable us to support all customers in their efforts to consume less fuel and paper. We continue to
 digitize loan origination and deposit account opening processes, reducing trips to the bank and paper documents for our customers. Across our footprint, we host community shred days with multiple confidential document destruction companies to
 promote safe document disposal and recycling.

 Supervision and Regulation

 The Company, the Bank and certain of its non-banking subsidiaries are subject to extensive regulation under federal and state laws. The regulatory framework applicable to bank holding companies
 and their subsidiary banks is intended to protect depositors, federal deposit insurance funds and the stability of the U.S. banking system. This system is not designed to protect equity investors in bank holding companies, such as the Company.

 Table

 Set forth below is a summary of the significant laws and regulations applicable to the Company and its subsidiaries. The description that follows is qualified in its entirety by reference to the
 full text of the statutes, regulations and policies that are described. Such statutes, regulations and policies are subject to ongoing review by Congress and state legislatures and federal and state regulatory agencies. A change in any of the
 statutes, regulations or regulatory policies applicable to the Company and its subsidiaries could have a material effect on the results of the Company.

 Overview

 The Company is a registered bank holding company and financial holding company under the Bank Holding Company Act of 1956, as amended (the "BHC Act"), and is subject to the supervision of, and
 regular examination by, the Board of Governors of the Federal Reserve System (the "Federal Reserve Board" or "FRB") as its primary federal regulator. The Company is also subject to the jurisdiction of the Securities and Exchange Commission ("SEC")
 and is subject to the disclosure and other regulatory requirements of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended (the "Exchange Act"), as administered by the SEC. The Company's common stock is listed
 on the NASDAQ Global Select market under the ticker symbol, "NBTB," and the Company is subject to the NASDAQ stock market rules.

 The Bank is chartered as a national banking association under the National Bank Act. The Bank is subject to the supervision of, and to regular examination by, the Office of the Comptroller of the
 Currency ("OCC") as its chartering authority and primary federal regulator. The Bank is also subject to the supervision and regulation, to a limited extent, of the FDIC as its deposit insurer. Financial products and services offered by the Company
 and the Bank are subject to federal consumer protection laws and implementing regulations promulgated by the Consumer Financial Protection Bureau ("CFPB"). The Company and the Bank are also subject to oversight by state attorneys general for
 compliance with state consumer protection laws. The Bank's deposits are insured by the FDIC up to the applicable deposit insurance limits in accordance with FDIC laws and regulations. The non-bank subsidiaries of the Company and the Bank are
 subject to federal and state laws and regulations, including regulations of the FRB and the OCC, respectively.

 Since the enactment of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the "Dodd-Frank Act"), U.S. banks and financial services firms have been subject to enhanced
 regulation and oversight.

 Federal Bank Holding Company Regulation

 The Company is a bank holding company as defined by the BHC Act. The BHC Act generally limits the business of the Company to banking, managing or controlling banks and other activities that the
 FRB has determined to be so closely related to banking "as to be a proper incident thereto." The Company has also qualified for and elected to be a financial holding company. Financial holding companies may engage in any activity, or acquire and
 retain the shares of a company engaged in any activity, that is either (1) financial in nature or incidental to such financial activity (as determined by the FRB in consultation with the Secretary of the Treasury), or (2) complementary to a
 financial activity and that does not pose a substantial risk to the safety and soundness of depository institutions or the financial system (as solely determined by the FRB). If a bank holding company seeks to engage in the broader range of
 activities permitted under the BHC Act for financial holding companies, (1) the bank holding company and all of its depository institution subsidiaries must be "well-capitalized" and "well-managed," as defined in the FRB's Regulation Y and (2) it
 must file a declaration with the FRB that it elects to be a "financial holding company." In order for a financial holding company to commence any activity that is financial in nature, incidental thereto, or complementary to a financial activity, or
 to acquire a company engaged in any such activity permitted by the BHC Act, each insured depository institution subsidiary of the financial holding company must have received a rating of at least "satisfactory" in its most recent examination under
 the Community Reinvestment Act of 1977 (the "CRA"). See the section titled "Community Reinvestment Act of 1977" for further information relating to the CRA. The Federal Reserve has the power to order any bank holding company or its subsidiaries to
 terminate any activity or to terminate its ownership or control of any subsidiary when the Federal Reserve has reasonable grounds to believe that continuation of such activity or such ownership or control constitutes a serious risk to the financial
 soundness, safety or stability of any bank subsidiary of the bank holding company.

 Regulation of Mergers and Acquisitions

 The BHC Act, the Bank Merger Act and other federal and state statutes regulate acquisitions of depository institutions and their holding companies. The BHC Act requires prior FRB approval for a
 bank holding company to acquire, directly or indirectly, 5% or more of any class of voting securities of a commercial bank or its parent holding company and for a company, other than a bank holding company, to acquire 25% or more of any class of
 voting securities of a bank or bank holding company (and sometimes a lower percentage if there are other indications of control). Under the Change in Bank Control Act, any person, including a company, may not acquire, directly or indirectly,
 control of a bank without providing 60 days' prior notice and receiving a non-objection from the appropriate federal banking agency.

 Under the Bank Merger Act, prior approval of the OCC is required for a national bank to merge with another bank where the national bank is the surviving bank or to purchase the assets or assume
 the deposits of another bank. In reviewing applications seeking approval of merger and acquisition transactions, the federal banking agencies will consider, among other criteria, the competitive effect and public benefits of the transactions, the
 capital position of the combined banking organization, the applicant's performance record under the CRA and the effectiveness of the subject organizations in combating money laundering activities.

 As a financial holding company, the Company is permitted to acquire control of non-depository institutions engaged in activities that are financial in nature and in activities that are incidental
 to financial activities without prior FRB approval. However, the BHC Act, as amended by the Dodd-Frank Act, requires prior written approval from the FRB or prior written notice to the FRB before a financial holding company may acquire control of a
 company with consolidated assets of $10 billion or more.

 Capital Distributions

 The principal source of the Company's liquidity is dividends from the Bank. The OCC oversees the ability of the Bank to make capital distributions, including dividends. The OCC generally
 prohibits a depository institution from making any capital distributions (including payment of a dividend) or paying any management fee to its parent holding company if the bank would thereafter be undercapitalized. The OCC's prior approval is
 required if the total of all dividends declared by a national bank in any calendar year would exceed the sum of the bank's net income for that year and its undistributed net income for the preceding two calendar years, less any required transfers
 to surplus. The National Bank Act also prohibits national banks from paying dividends that would be greater than the bank's undivided profits after deducting statutory bad debt in excess of the bank's allowance for loan losses.

 The federal banking agencies have indicated that paying dividends that deplete a bank's capital base to an inadequate level would be an unsafe and unsound banking practice and that banking
 organizations should generally pay dividends only out of current operating earnings. The appropriate federal regulatory authority is authorized to determine, based on the financial condition of a bank holding company or a bank, that the payment of
 dividends would be an unsafe or unsound practice and to prohibit such payment.

 Affiliate and Insider Transactions

 Transactions between the Bank and its affiliates, including the Company, are governed by Sections 23A and 23B of the Federal Reserve Act (the "FRA") and the FRB's implementation of Regulation W.
 An "affiliate" of a bank includes any company or entity that controls, is controlled by or is under common control with such bank. In a bank holding company context, at a minimum, the parent holding company of a bank and companies that are
 controlled by such parent holding company, are affiliates of the bank. Generally, Sections 23A and 23B of the FRA are intended to protect insured depository institutions from losses in transactions with affiliates. These sections place quantitative
 and qualitative limitations on covered transactions between the Bank and its affiliates and require that all transactions between a bank and its affiliates occur on market terms that are consistent with safe and sound banking practices.

 Section 22(h) of the FRA and its implementation of Regulation O restricts loans to the Bank's and its affiliates' directors, executive officers and principal stockholders ("Insiders"). Under
 Section 22(h), loans to Insiders and their related interests may not exceed, together with all other outstanding loans to such persons and affiliated entities, the Bank's loan-to-one borrower limit. Loans to Insiders above specified amounts must
 receive the prior approval of the Bank's Board of Directors. Further, under Section 22(h) of the FRA, loans to directors, executive officers and principal stockholders must be made on terms substantially the same as offered in comparable
 transactions to other persons, except that such Insiders may receive preferential loans made under a benefit or compensation program that is widely available to the Bank's employees and does not give preference to the Insider over the employees.
 Section 22(g) of the FRA places additional limitations on loans to the Bank's and its affiliates' executive officers.

 Federal Deposit Insurance and Brokered Deposits

 The FDIC's deposit insurance limit is $250,000 per depositor, per insured bank, for each account ownership category, in accordance with applicable FDIC regulations. The Bank's deposit accounts
 are fully insured by the FDIC Deposit Insurance Fund (the "DIF") up to the deposit insurance limits in accordance with applicable laws and regulations.

 The FDIC uses a risk-based assessment system that imposes insurance premiums based upon a risk matrix that takes into account a bank's capital level and supervisory rating ("CAMELS rating"). The
 risk matrix uses different risk categories distinguished by capital levels and supervisory ratings. As a result of the Dodd-Frank Act, the base for deposit insurance assessments is the consolidated average assets less average tangible equity.
 Assessment rates are calculated using formulas that take into account the risk of the institution being assessed.

 In November 2023, the FDIC announced a special assessment on all insured depository institutions with more than $5 billion in total assets, including the Bank, in order to recover the loss to the
 DIF associated with protecting uninsured depositors following the closures of Silicon Valley Bank and Signature Bank. The assessment base for the special assessment was equal to an insured depository institution's estimated uninsured deposits
 reported as of December 31, 2022, adjusted to exclude the first $5 billion. The Company's uninsured deposits as of December 31, 2022 were under $5 billion and therefore the Company will not be subject to this special assessment.

 Under FDIC laws and regulations, no FDIC-insured depository institution can accept brokered deposits unless it is well-capitalized or unless it is adequately capitalized and receives a waiver
 from the FDIC. Applicable laws and regulations also limit the interest rate that any depository institution that is not well-capitalized may pay on brokered deposits.

 Under the Federal Deposit Insurance Act ("FDIA"), the FDIC may terminate deposit insurance upon a finding that the institution has engaged in unsafe and unsound practices, is in an unsafe or
 unsound condition to continue operations or has violated any applicable law, regulation, rule, order or condition imposed by the FDIC. The Bank's management is not aware of any practice, condition or violation that might lead to the termination of
 its deposit insurance.

 Table

 Federal Home Loan Bank System

 The Bank is also a member of the Federal Home Loan Bank ("FHLB") of New York, which provides a central credit facility primarily for member institutions for home mortgage and neighborhood
 lending. The Bank is subject to the rules and requirements of the FHLB, including the requirement to acquire and hold shares of capital stock in the FHLB in an amount at least equal to the sum of 0.125% of mortgage related assets at the beginning
 of each year. The Bank was in compliance with FHLB rules and requirements as of December 31, 2023.

 Debit Card Interchange Fees

 The Dodd-Frank Act requires that any interchange transaction fee charged for a debit transaction be reasonable and proportional to the cost incurred by the issuer for the transaction. FRB
 regulations mandated by the Dodd-Frank Act limit interchange fees on debit cards to a maximum of 21 cents per transaction plus 5 basis points of the transaction amount. The rule also permits a fraud-prevention adjustment of 1 cent per transaction
 conditioned upon an issuer developing, implementing and updating reasonably designed fraud-prevention policies and procedures. Issuers that, together with their affiliates, have less than $10 billion of assets, are exempt from the debit card
 interchange fee standards. In addition, FRB regulations prohibit all issuers, including the Company and the Bank, from restricting the number of networks over which electronic debit transactions may be processed to less than two unaffiliated
 networks.

 In December 2020, the OCC, together with the Board of Governors of the Federal Reserve System and the FDIC, issued an interim final rule to temporarily mitigate transition costs related to the
 coronavirus ("COVID-19") pandemic on community banking organizations with less than $10 billion in total assets as of December 31, 2019. The rule allowed organizations, including the Company, to use assets as of December 31, 2019, to determine the
 applicability of various regulatory asset thresholds. During 2020, the Company crossed the $10 billion threshold but elected to delay the regulatory implications of crossing the $10 billion threshold until 2022 for these debit card interchange fee
 standards. The Company became subject to the new standards starting in July 2022.

 Source of Strength Doctrine

 FRB policy requires bank holding companies to act as a source of financial and managerial strength to their subsidiary banks. Section 616 of the Dodd-Frank Act codifies the requirement that bank
 holding companies serve as a source of financial strength to their subsidiary depository institutions. A bank holding company's failure to meet its obligations to serve as a source of strength to its subsidiary banks will generally be considered by
 the FRB to be an unsafe and unsound banking practice or a violation of FRB regulations or both. As a result, the Company is expected to commit resources to support the Bank, including at times when the Company may not be in a financial position to
 provide such resources. Any capital loan by the Company to the Bank is subordinate in right of payment to deposits and to certain other indebtedness of such subsidiary banks. The U.S. Bankruptcy Code provides that, in the event of a bank holding
 company's bankruptcy, any commitment by the bank holding company to a federal bank regulatory agency to maintain the capital of a subsidiary bank will be assumed by the bankruptcy trustee and entitled to priority of payment.

 In addition, under the National Bank Act, if the Bank's capital stock is impaired by losses or otherwise, the OCC is authorized to require payment of the deficiency by assessment upon the
 Company. If the assessment is not paid within three months, the OCC could order a sale of Bank stock held by the Company to cover any deficiency.

 Capital Adequacy

 In July 2013, the FRB, the OCC and the FDIC approved final rules (the "Capital Rules") that established a new capital framework for U.S. banking organizations. The Capital Rules generally
 implement the Basel Committee on Banking Supervision's (the "Basel Committee") December 2010 final capital framework referred to as "Basel III" for strengthening international capital standards. The Capital Rules revise the definitions and the
 components of regulatory capital, as well as address other issues affecting the numerator in banking institutions' regulatory capital ratios. The Capital Rules also address asset risk weights and other matters affecting the denominator in banking
 institutions' regulatory capital ratios and replace the existing general risk-weighting approach with a more risk-sensitive approach.

 The Capital Rules: (1) require a capital measure called "Common Equity Tier 1" ("CET1") and related regulatory capital ratio of CET1 to risk-weighted assets; (2) specify that Tier 1 capital
 consists of CET1 and "Additional Tier 1 capital" instruments meeting certain revised requirements; (3) mandate that most deductions/adjustments to regulatory capital measures be made to CET1 and not to the other components of capital; and (4)
 expand the scope of the deductions from and adjustments to capital as compared to existing regulations. Under the Capital Rules, for most banking organizations, including the Company, the most common form of Additional Tier 1 capital is
 non-cumulative perpetual preferred stock and the most common forms of Tier 2 capital are subordinated notes and a portion of the allocation for loan losses, in each case, subject to the Capital Rules' specific requirements.

 Table

 Pursuant to the Capital Rules, the minimum capital ratios as of January 1, 2015 are:

 4.5% CET1 to risk-weighted assets;

 6.0% Tier 1 capital (CET1 plus Additional Tier 1 capital) to risk-weighted assets;

 8.0% Total capital (Tier 1 capital plus Tier 2 capital) to risk-weighted assets; and

 4.0% Tier 1 capital to average consolidated assets as reported on consolidated financial statements (known as the "leverage ratio").

 The Capital Rules also require a "capital conservation buffer," composed entirely of CET1, on top of these minimum risk-weighted asset ratios. The capital conservation buffer is designed to
 absorb losses during periods of economic stress. Banking institutions with a ratio of CET1 to risk-weighted assets above the minimum but below the capital conservation buffer will face constraints on dividends, equity and other capital instrument
 repurchases and compensation based on the amount of the shortfall. The capital conservation buffer was phased in incrementally until when, on January 1, 2019, the capital conservation buffer was fully phased in, resulting in the capital standards
 applicable to the Company and the Bank including an additional capital conservation buffer of 2.5% of CET1, and effectively resulting in minimum ratios inclusive of the capital conservation buffer of (1) CET1 to risk-weighted assets of at least 7%,
 (2) Tier 1 capital to risk-weighted assets of at least 8.5% and (3) Total capital to risk-weighted assets of at least 10.5%. The risk-weighting categories in the Capital Rules are standardized and include a risk-sensitive number of categories,
 depending on the nature of the assets, generally ranging from 0% for U.S. government and agency securities, to 600% for certain equity exposures and resulting in higher risk weights for a variety of asset classes. The Capital Rules provide for a
 number of deductions from and adjustments to CET1.

 In addition, under the prior general risk-based capital rules, the effects of accumulated other comprehensive income or loss ("AOCI") items included in stockholders' equity (for example,
 marks-to-market of securities held in the available for sale ("AFS") portfolio) under generally accepted accounting principles in the United States of America ("GAAP") were excluded for the purposes of determining regulatory capital ratios. Under
 the Capital Rules, the effects of certain AOCI items are not excluded; however, banking organizations not using the advanced approaches, including the Company and the Bank, were permitted to make a one-time permanent election to continue to exclude
 these items in January 2015. The Capital Rules also preclude certain hybrid securities, such as trust preferred securities issued after May 19, 2010, from inclusion in bank holding companies' Tier 1 capital.

 Management believes that the Company is in compliance with the targeted capital ratios.

 Prompt Corrective Action and Safety and Soundness

 Pursuant to Section 38 of the FDIA, federal banking agencies are required to take "prompt corrective action" ("PCA") should an insured depository institution fail to meet certain capital adequacy
 standards. At each successive lower capital category, an insured depository institution is subject to more restrictions and prohibitions, including restrictions on growth, restrictions on interest rates paid on deposits, restrictions or
 prohibitions on payment of dividends and restrictions on the acceptance of brokered deposits. Furthermore, if an insured depository institution is classified in one of the undercapitalized categories, it is required to submit a capital restoration
 plan to the appropriate federal banking agency and the holding company must guarantee the performance of that plan. Based upon its capital levels, a bank that is classified as well-capitalized, adequately capitalized or undercapitalized, may be
 treated as though it were in the next lower capital category if the appropriate federal banking agency, after notice and opportunity for hearing, determines that an unsafe or unsound condition or an unsafe or unsound practice, warrants such
 treatment.

 For purposes of PCA, to be: (1) well-capitalized, an insured depository institution must have a total risk based capital ratio of at least 10%, a Tier 1 risk based capital ratio of at least 8%, a
 CET1 risk based capital ratio of at least 6.5%, and a Tier 1 leverage ratio of at least 5%; (2) adequately capitalized, an insured depository institution must have a total risk based capital ratio of at least 8%, a Tier 1 risk based capital ratio
 of at least 6%, a CET1 risk based capital ratio of at least 4.5%, and a Tier 1 leverage ratio of at least 4%; (3) undercapitalized, an insured depository institution would have a total risk based capital ratio of less than 8%, a Tier 1 risk based
 capital ratio of less than 6%, a CET1 risk based capital ratio of less than 4.5%, and a Tier 1 leverage ratio of less than 4%; (4) significantly undercapitalized, an insured depository institution would have a total risk based capital ratio of less
 than 6%, a Tier 1 risk based capital ratio of less than 4%, a CET1 risk based capital ratio of less than 3%, and a Tier 1 leverage ratio of less than 3%; (5) critically undercapitalized, an insured depository institution would have a ratio of
 tangible equity to total assets that is less than or equal to 2%. At December 31, 2023, the Bank qualified as "well-capitalized" under applicable regulatory capital standards.

 Bank holding companies and insured depository institutions may also be subject to potential enforcement actions of varying levels of severity by the federal banking agencies for unsafe or unsound
 practices in conducting their business or for violation of any law, rule, regulation, condition imposed in writing by the agency or term of a written agreement with the agency. In more serious cases, enforcement actions may include the issuance of
 directives to increase capital; the issuance of formal and informal agreements; the imposition of civil monetary penalties; the issuance of a cease and desist order that can be judicially enforced; the issuance of removal and prohibition orders
 against officers, directors and other institution-affiliated parties; the termination of the insured depository institution's deposit insurance; the appointment of a conservator or receiver for the insured depository institution; and the
 enforcement of such actions through injunctions or restraining orders based upon a judicial determination that the FDIC, as receiver, would be harmed if such equitable relief was not granted.

 Volcker Rule

 Section 619 of the Dodd-Frank Act, commonly known as the Volcker Rule, restricts the ability of banking entities from: (1) engaging in "proprietary trading" and (2) investing in or sponsoring
 certain covered funds, subject to certain limited exceptions. Under the Economic Growth, Regulatory Reform and Consumer Protection Act ("EGRRCPA"), depository institutions and their holding companies with less than $10 billion in assets, are
 excluded from the prohibitions of the Volcker Rule. During 2020, the Company crossed the $10 billion threshold, accordingly, we are subject to the Volcker Rule again. Given the Company's size and the scope of its activities, the implementation of
 the Volcker Rule did not have a significant effect on its consolidated financial statements.

 Depositor Preference

 The FDIA provides that, in the event of the "liquidation or other resolution" of an insured depository institution, the claims of depositors of the institution, including the claims of the FDIC
 as subrogee of insured depositors and certain claims for administrative expenses of the FDIC as a receiver, will have priority over other general unsecured claims against the institution. If an insured depository institution fails, insured and
 uninsured depositors, along with the FDIC, will have priority in payment ahead of unsecured, non-deposit creditors, including the parent bank holding company, with respect to any extensions of credit they have made to such insured depository
 institution.

 Consumer Protection and CFPB Supervision

 The Dodd-Frank Act centralized responsibility for consumer financial protection by creating the CFPB, an independent agency charged with responsibility for implementing, enforcing and examining
 compliance with federal consumer financial laws. The Company grew its asset base in excess of $10 billion in 2020. The Company is now subject to the CFPB's examination authority with regard to compliance with federal consumer financial laws and
 regulations, in addition to the OCC as the primary regulatory of the Bank. Under the Dodd-Frank Act, state attorneys general are also empowered to enforce rules issued by the CFPB.

 The Company is subject to federal consumer financial statutes and the regulations promulgated thereunder including, but not limited to:

 the Truth-In-Lending Act, governing disclosures of credit terms to consumer borrowers;

 the Equal Credit Opportunity Act ("ECOA"), prohibiting discrimination in connection with the extension of credit;

 the Home Mortgage Disclosure Act ("HMDA"), requiring home mortgage lenders, including the Bank, to make available to the public expanded information regarding the pricing of
 home mortgage loans, including the "rate spread" between the annual percentage rate and the average prime offer rate for mortgage loans of a comparable type;

 the Fair Credit Reporting Act ("FCRA"), governing the provision of consumer information to credit reporting agencies and the use of consumer information; and

 the Fair Debt Collection Practices Act, governing the manner in which consumer debts may be collected by collection agencies.

 The Bank's failure to comply with any of the consumer financial laws can result in civil actions, regulatory enforcement action by the federal banking agencies and the U.S. Department of Justice.

 USA PATRIOT Act

 The Bank Secrecy Act ("BSA"), as amended by the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 ("USA PATRIOT Act"),
 imposes obligations on U.S. financial institutions, including banks and broker-dealer subsidiaries, to implement policies, procedures and controls which are reasonably designed to detect and report instances of money laundering and the financing of
 terrorism. Financial institutions also are required to respond to requests for information from federal banking agencies and law enforcement agencies. Information sharing among financial institutions for the above purposes is encouraged by an
 exemption granted to complying financial institutions from the privacy provisions of the GLBA and other privacy laws. Financial institutions that hold correspondent accounts for foreign banks or provide private banking services to foreign
 individuals are required to take measures to avoid dealing with certain foreign individuals or entities, including foreign banks with profiles that raise money laundering concerns and are prohibited from dealing with foreign "shell banks" and
 persons from jurisdictions of particular concern. The primary federal banking agencies and the Secretary of the Treasury have adopted regulations to implement several of these provisions. Since May 11, 2018, the Bank has been required to comply
 with the Customer Due Diligence Rule, which clarified and strengthened the existing obligations for identifying new and existing customers and explicitly included risk-based procedures for conducting ongoing customer due diligence. All financial
 institutions also are required to establish internal anti-money laundering programs. The effectiveness of a financial institution in combating money laundering activities is a factor to be considered in any application submitted by the financial
 institution under the Bank Merger Act. The Company has a BSA and USA PATRIOT Act Board-approved compliance program commensurate with its risk profile.

 Table

 Identity Theft Prevention

 The FCRA's Red Flags Rule requires financial institutions with covered accounts (e.g., consumer bank accounts and loans) to develop, implement and administer an identity theft prevention program.
 This program must include reasonable policies and procedures to detect suspicious patterns or practices that indicate the possibility of identity theft, such as inconsistencies in personal information or changes in account activity.

 Office of Foreign Assets Control Regulation

 The United States government has imposed economic sanctions that affect transactions with designated foreign countries, nationals and others. These are typically known as the "OFAC" rules based
 on their administration by the U.S. Treasury Department Office of Foreign Assets Control ("OFAC"). The OFAC-administered sanctions targeting countries take many different forms. Generally, they contain one or more of the following elements: (1)
 restrictions on trade with or investment in a sanctioned country, including prohibitions against direct or indirect imports from and exports to a sanctioned country and prohibitions on "U.S. persons" engaging in financial transactions relating to
 making investments in or providing investment-related advice or assistance to a sanctioned country; and (2) a blocking of assets in which the government or specially designated nationals of the sanctioned country have an interest, by prohibiting
 transfers of property subject to U.S. jurisdiction (including property in the possession or control of U.S. persons). Blocked assets (property and bank deposits) cannot be paid out, withdrawn, set off or transferred in any manner without a license
 from OFAC. Failure to comply with these sanctions could have serious legal and reputational consequences.

 Financial Privacy and Data Security

 The Company and the Bank are subject to federal laws, including the GLBA and certain state laws containing consumer privacy protection provisions. These provisions limit the ability of banks and
 other financial institutions to disclose nonpublic information about consumers to affiliated and non-affiliated third parties and limit the reuse of certain consumer information received from nonaffiliated financial institutions. These provisions
 require notice of privacy policies to clients and, in some circumstances, allow consumers to prevent disclosure of certain nonpublic personal information to affiliates or non-affiliated third parties by means of "opt out" or "opt in"
 authorizations.

 The GLBA requires that financial institutions implement comprehensive written information security programs that include administrative, technical and physical safeguards to protect consumer
 information. Further, pursuant to interpretive guidance issued under the GLBA and certain state laws, financial institutions are required to notify clients of security breaches resulting in unauthorized access to their personal information. The
 Bank follows all GLBA obligations.

 The Bank is also subject to data security standards, privacy and data breach notice requirements, primarily those issued by the OCC. The federal banking agencies, through the Federal Financial
 Institutions Examination Council, have adopted guidelines to encourage financial institutions to address cyber security risks and identify, assess and mitigate these risks, both internally and at critical third party services providers.

 Community Reinvestment Act of 1977

 The Bank has a responsibility under the CRA, as implemented by OCC regulations, to help meet the credit needs of the communities it serves, including low- and moderate-income neighborhoods. The
 CRA does not establish specific lending requirements or programs for financial institutions nor does it limit an institution's discretion to develop the types of products and services that it believes are best suited to its particular community,
 consistent with the CRA. Regulators periodically assess the Bank's record of compliance with the CRA. The Bank's failure to comply with the CRA could, at a minimum, result in regulatory restrictions on its activities and the activities of the
 Company. The Bank's most current CRA rating was "Satisfactory."

 Table

 Future Legislative Initiatives

 Congress, state legislatures and financial regulatory agencies may introduce various legislative and regulatory initiatives that could affect the financial services industry, generally. Such
 initiatives may include proposals to expand or contract the powers of bank holding companies and/or depository institutions or proposals to substantially change the financial institution regulatory system. Such legislation could change banking
 statutes and the operating environment of the Company in substantial and unpredictable ways. If enacted, such legislation could increase or decrease the cost of doing business, limit or expand permissible activities or affect the competitive
 balance among banks, savings associations, credit unions and other financial institutions. The Company cannot predict whether any such legislation will be enacted, and, if enacted, the effect that it or any implementing regulations would have on
 the financial condition or results of operations of the Company. A change in statutes, regulations or regulatory policies applicable to the Company or any of its subsidiaries could have a material effect on the business of the Company.

 Employees

 At December 31, 2023, the Company had 2,034 full-time equivalent employees. The Company's employees are not presently represented by any collective bargaining group.

 ITEM 1A.

 RISK FACTORS

 There are risks inherent to the Company's business. The material risks and uncertainties that management believes affect the Company are described below. Any of the following risks could affect
 the Company's financial condition and results of operations and could be material and/or adverse in nature. You should consider all of the following risks together with all of the other information in this Annual Report on Form 10-K.

 Risks Related to our Business and Industry

 The Company may be adversely affected by conditions in the financial markets and economic conditions generally.

 Key macroeconomic conditions historically have affected the Company's business, results of operations and financial condition and are likely to affect them in the future. Consumer confidence,
 unemployment and other economic indicators are among the factors that often impact consumer spending and payment behavior and demand for credit. The Company relies primarily on interest and fees on our loan receivables to generate net earnings. The
 economy in the United States and globally has experienced volatility in recent years and may continue to do so for the foreseeable future. There can be no assurance that economic conditions will not worsen. Unfavorable or uncertain economic
 conditions can be caused by declines in economic growth, business activity or investor or business confidence, limitations on the availability or increases in the cost of credit and capital, increases in inflation or interest rates, the timing and
 impact of geopolitical uncertainties, natural disasters, epidemics and pandemics, terrorist attacks, acts of war or a combination of these or other factors. Federal budget deficit concerns and the potential for political conflict over legislation
 to fund U.S. government operations and raise the U.S. government's debt limit may increase the possibility of a default by the U.S. government on its debt obligations, related credit-rating downgrades, or an economic recession in the United States.
 A worsening of business and economic conditions could have adverse effects on our business, including the following:

 investors may have less confidence in the equity markets in general and in financial services industry stocks in particular, which could place downward pressure on the
 Company's stock price and resulting market valuation;

 consumer and business confidence levels could be lowered and cause declines in credit usage and adverse changes in payment patterns, causing increases in delinquencies and
 default rates;

 the Company's ability to assess the creditworthiness of its customers may be impaired if the models and approaches the Company uses to select, manage and underwrite its
 customers become less predictive of future behaviors;

 the Company could suffer decreases in demand for loans or other financial products and services or decreased deposits or other investments in accounts with the Company;

 demand for and income received from the Company's fee-based services could decline;

 customers of the Company's trust and benefit plan administration business may liquidate investments, which together with lower asset values, may reduce the level of assets
 under management and administration and thereby decrease the Company's investment management and administration revenues;

 competition in the financial services industry could intensify as a result of the increasing consolidation of financial services companies in connection with current market
 conditions or otherwise; and

 the value of loans and other assets or collateral securing loans may decrease.

 Deterioration in local economic conditions may negatively impact our financial performance.

 The Company's success depends primarily on the general economic conditions in upstate New York, northeastern Pennsylvania, southern New Hampshire, western Massachusetts, Vermont, southern Maine,
 central and northwestern Connecticut and the specific local markets in which the Company operates. Unlike larger national or other regional banks that are more geographically diversified, the Company provides banking and financial services to
 customers primarily in the upstate New York areas of Norwich, Syracuse, Oneonta, Amsterdam-Gloversville, Albany, Binghamton, Utica-Rome, Plattsburgh, Glens Falls and Ogdensburg-Massena, the northeastern Pennsylvania areas of Scranton and
 Wilkes-Barre, Berkshire County, Massachusetts, southern New Hampshire, Vermont, southern Maine and central and northwestern Connecticut. The local economic conditions in these areas have a significant impact on the demand for the Company's products
 and services as well as the ability of the Company's customers to repay loans, the value of the collateral securing loans and the stability of the Company's deposit funding sources.

 A downturn in our local economies could cause significant increases in nonperforming loans, which could negatively impact our earnings. Declines in real estate values in our market areas could
 cause any of our loans to become inadequately collateralized, which would expose us to greater risk of loss. Additionally, a decline in real estate values could result in the decline of originations of such loans, as most of our loans and the
 collateral securing our loans are located in those areas.

 Table

 Severe weather, flooding and other effects of climate change and other natural disasters could adversely affect our financial condition, results of
 operations or liquidity.

 Our branch locations and our customers' properties may be adversely impacted by flooding, wildfires, high winds and other effects of severe weather conditions that may be caused or exacerbated by
 climate change. These events can force property closures, result in property damage and/or result in delays in expansion, development or renovation of our properties and those of our customers. Even if these events do not directly impact our
 properties or our customers' properties, they may impact us and our customers through increased insurance, energy or other costs. In addition, changes in laws or regulations, including federal, state or city laws, relating to climate change could
 result in increased capital expenditures to improve the energy efficiency of our branch locations and/or our customers' properties.

 Given that climate change could impose systemic risks upon the financial sector, either via disruptions in economic activity resulting from the physical impacts of climate
 change or changes in policies as the economy transitions to a less carbon-intensive environment, the Company may face regulatory risk of increasing focus on the Company's resilience to climate-related risks, including in the context of stress
 testing for various climate stress scenarios. Ongoing legislative or regulatory uncertainties and changes regarding climate risk management and practices may result in higher regulatory, compliance, credit and reputational risks and costs.

 Variations in interest rates could adversely affect our results of operations and financial condition.

 The Company's earnings and financial condition, like that of most financial institutions, are largely dependent upon net interest income, which is the difference between interest earned from
 loans and investments and interest paid on deposits and borrowings. The narrowing of interest rate spreads could adversely affect the Company's earnings and financial condition. The Company cannot predict with certainty, or control, changes in
 interest rates. Regional and local economic conditions and the policies of regulatory authorities, including monetary policies of the FRB, affect rates and, therefore, interest income and interest expense. In order to address rising inflation, the
 FRB raised interest rates in 2022 and in the first half 2023 and, while the Federal funds rate has remained unchanged over recent months, the FRB may again raise interest rates in response to inflation. The magnitude of any such increase is not
 currently known. High interest rates could also affect the amount of loans that the Company can originate because higher rates could cause customers to apply for fewer mortgages or cause depositors to shift funds from accounts that have a
 comparatively lower cost to accounts with a higher cost. The Company may also experience customer attrition due to competitor pricing on both deposits and loans. If the cost of interest-bearing deposits increases at a rate greater than the yields
 on interest-earning assets increase, net interest income will be negatively affected. Changes in the asset and liability mix may also affect net interest income. Similarly, lower interest rates cause higher yielding assets to prepay and floating or
 adjustable rate assets to reset to lower rates. If the Company is not able to reduce its funding costs sufficiently, due to either competitive factors or the maturity schedule of existing liabilities, then the Company's net interest margin will
 decline.

 Any substantial or unexpected change in, or prolonged change in market interest rates could have a material adverse effect on the Company's financial condition and results of operations. See the
 section captioned "Net Interest Income" in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations and Item 7A. Quantitative and Qualitative Disclosure About Market Risk located elsewhere in this report for
 further discussion related to the Company's management of interest rate risk.

 Our lending, and particularly our emphasis on commercial lending, exposes us to the risk of losses upon borrower default.

 As of December 31, 2023, approximately 52% of the Company's loan portfolio consisted of commercial and industrial, agricultural, commercial construction and commercial real estate loans. These
 types of loans generally expose a lender to greater risk of non-payment and loss than residential real estate loans because repayment of the loans often depends on the successful operation of the property, the income stream of the borrowers and,
 for construction loans, the accuracy of the estimate of the property's value at completion of construction and the estimated cost of construction. Such loans typically involve larger loan balances to single borrowers or groups of related borrowers
 compared to residential real estate loans. Because the Company's loan portfolio contains a significant number of commercial and industrial, agricultural, construction and commercial real estate loans with relatively large balances, the
 deterioration of one or a few of these loans could cause a significant increase in nonperforming loans. An increase in nonperforming loans could result in a net loss of earnings from these loans, an increase in the provision for loan losses and/or
 an increase in loan charge-offs, all of which could have a material adverse effect on the Company's financial condition and results of operations. See the section captioned "Loans" in Item 7. Management's Discussion and Analysis of Financial
 Condition and Results of Operations located elsewhere in this report for further discussion related to our commercial and industrial, agricultural, construction and commercial real estate loans.

 Table

 Our allowance for loan losses may not be sufficient to cover actual loan losses, which could have a material adverse effect on our business, financial
 condition and results of operations.

 The Company maintains an allowance for loan losses, which is an allowance established through a provision for loan losses charged to expense, that represents management's best estimate of
 expected credit losses within the existing portfolio of loans. The allowance, in the judgment of management, is necessary to reserve for estimated loan losses and risks inherent in the loan portfolio. The determination of the appropriate level of
 the allowance for loan losses inherently involves a high degree of subjectivity and requires the Company to make significant estimates of current credit risks, forecast economic conditions and future trends, all of which may undergo material
 changes. Changes in economic conditions affecting borrowers, new information regarding existing loans, identification of additional problem loans and other factors, both within and outside of the Company's control, may require an increase in the
 allowance for loan losses. Bank regulatory agencies periodically review the Company's allowance for loan losses and may require an increase in the provision for loan losses or the recognition of further loan charge-offs, based on judgments
 different from those of management. In addition, if charge-offs in future periods exceed the allowance for loan losses, the Company may need additional provisions to increase the allowance for loan losses. These potential increases in the allowance
 for loan losses would result in a decrease in net income and, possibly, capital and may have a material adverse effect on the Company's financial condition and results of operations. See the section captioned "Risk Management – Credit Risk" in Item
 7. Management's Discussion and Analysis of Financial Condition and Results of Operations located elsewhere in this report for further discussion related to the Company's process for determining the appropriate level of the allowance for loan
 losses. Management expects that the Current Expected Credit Losses ("CECL") model may create more volatility in the level of our allowance for loan losses from quarter to quarter as changes in the level of allowance for loan losses will be
 dependent upon, among other things, macroeconomic forecasts and conditions, loan portfolio volumes and credit quality.

 Strong competition within our industry and market area could adversely affect our performance and slow our growth.

 The Company faces substantial competition in all areas of its operations from a variety of different competitors, many of which are larger and may have more financial resources. Such competitors
 primarily include national, regional and community banks within the various markets in which the Company operates. Additionally, various banks continue to enter or have announced plans to enter the market areas in which the Company currently
 operates. The Company also faces competition from many other types of financial institutions, including, without limitation, savings and loans, credit unions, finance companies, brokerage firms, insurance companies and other financial
 intermediaries. The financial services industry could continue to become even more competitive as a result of legislative, regulatory and technological changes and continued consolidation. Technology has lowered barriers to entry and made it
 possible for non-banks to offer products and services traditionally provided by banks, such as automatic transfer and automatic payment systems. Many of the Company's competitors have fewer regulatory constraints and may have lower cost structures.
 Additionally, due to their size, many competitors may be able to achieve economies of scale and, as a result, may offer a broader range of products and services as well as better pricing for those products and services than the Company can.

 The Company's ability to compete successfully depends on a number of factors, including, among other things:

 the ability to develop, maintain and build upon long-term customer relationships based on top-quality service, high ethical standards and safe, sound assets;

 the ability to expand the Company's market position;

 the scope, relevance and pricing of products and services offered to meet customer needs and demands;

 the rate at which the Company introduces new products, services and technologies relative to its competitors;

 customer satisfaction with the Company's level of service;

 industry and general economic trends; and

 the ability to attract and retain talented employees.

 Failure to perform in any of these areas could significantly weaken the Company's competitive position, which could adversely affect the Company's growth and profitability, which, in turn, could
 have a material adverse effect on the Company's financial condition and results of operations.

 The Company is subject to liquidity risk, which could adversely affect net interest income and earnings.

 The purpose of the Company's liquidity management is to meet the cash flow obligations of its customers for both deposits and loans. Regulators are increasingly focused on liquidity risk after
 the bank failures of 2023. The primary liquidity measurement the Company utilizes is called basic surplus, which captures the adequacy of the Company's access to reliable sources of cash relative to the stability of its funding mix of average
 liabilities. This approach recognizes the importance of balancing levels of cash flow liquidity from short and long-term securities with the availability of dependable borrowing sources, which can be accessed when necessary. However, competitive
 pressure on deposit pricing could result in a decrease in the Company's deposit base or an increase in funding costs. In addition, liquidity will come under additional pressure if loan growth exceeds deposit growth. These scenarios could lead to a
 decrease in the Company's basic surplus measure to an amount below the minimum policy level of 5%. To manage this risk, the Company has the ability to purchase brokered time deposits, borrow against established borrowing facilities with other banks
 (Federal funds) and enter into repurchase agreements with investment companies. Depending on the level of interest rates applicable to these alternatives, the Company's net interest income, and therefore earnings, could be adversely affected. See
 the section captioned "Liquidity Risk" in Item 7.

 Table

 Our ability to service our debt, pay dividends and otherwise pay our obligations as they come due is substantially dependent on capital distributions from
 our subsidiaries.

 The Company is a separate and distinct legal entity from its subsidiaries. It receives substantially all of its revenue from dividends from its subsidiaries. These dividends are the principal
 source of funds to pay dividends on the Company's common stock and interest and principal on the Company's debt. Various federal and/or state laws and regulations limit the amount of dividends that the Bank may pay to the Company. In addition, the
 Company's right to participate in a distribution of assets upon a subsidiary's liquidation or reorganization is subject to the prior claims of the subsidiary's creditors. In the event the Bank is unable to pay dividends to the Company, the Company
 may not be able to service debt, pay obligations or pay dividends on the Company's common stock. The inability to receive dividends from the Bank could have a material adverse effect on the Company's business, financial condition and results of
 operations.

 A reduction in the Company's credit rating could adversely affect our business and/or the holders of our securities.

 The credit rating agency rating our indebtedness regularly evaluates the Company and the Bank. Credit ratings are based on a number of factors, including our financial strength and ability to
 generate earnings, as well as factors not entirely within our control, including conditions affecting the financial services industry generally and the economy and changes in rating methodologies. There can be no assurance that the Company will
 maintain our current credit ratings. A downgrade of the credit ratings of the Company or the Bank could adversely affect our access to liquidity and capital, significantly increase our cost of funds, and decrease the number of investors and
 counterparties willing to lend to the Company or purchase our securities. This could affect our growth, profitability, and financial condition, including liquidity.

 The Company relies on third parties to provide key components of its business infrastructure.

 The Company relies on third parties to provide key components for its business operations, such as data processing and storage, recording and monitoring transactions, online banking interfaces
 and services, internet connections and network access. While the Company selects these third party vendors carefully, it does not control their actions. Any problems caused by these third parties, including those resulting from breakdowns or other
 disruptions in communication services provided by a vendor, failure of a vendor to handle current or higher volumes, cyber-attacks and security breaches at a vendor, failure of a vendor to provide services for any reason or poor performance of
 services by a vendor, could adversely affect the Company's ability to deliver products and services to its customers and otherwise conduct its business. Financial or operational difficulties of a third party vendor could also hurt the Company's
 operations if those difficulties interfere with the vendor's ability to serve the Company. Replacing these third party vendors also could create significant delays and expense that adversely affect the Company's business and performance.

 There are substantial risks and uncertainties associated with the introduction or expansion of lines of business or new products and services within
 existing lines of business.

 From time to time, the Company may implement new lines of business or offer new products and services within existing lines of business. There are substantial risks and uncertainties associated
 with these efforts, particularly in instances where the markets are not fully developed. In developing and marketing new lines of business and/or new products and services, the Company may invest significant time and resources. Initial timetables
 for the introduction and development of new lines of business and/or new products or services may not be achieved and price and profitability targets may not prove attainable. External factors, such as compliance with regulations, competitive
 alternatives and shifting market preferences, may also impact the successful implementation of a new line of business or a new product or service. Furthermore, any new line of business and/or new product or service could have a significant impact
 on the effectiveness of the Company's system of internal controls. Failure to successfully manage these risks in the development and implementation of new lines of business or new products or services could have a material adverse effect on the
 Company's business, results of operations and financial condition.

 Risks Related to Legal, Governmental and Regulatory Changes

 We are subject to extensive government regulation and supervision, which may interfere with our ability to conduct our business and may negatively impact
 our financial results.

 We are subject to extensive federal and state regulation and supervision. Banking regulations are primarily intended to protect depositors' funds, the DIF and the safety and soundness of the
 banking system as a whole, not stockholders. These regulations affect the Company's lending practices, capital structure, investment practices, dividend policy and growth, among other things. Congress and federal regulatory agencies continually
 review banking laws, regulations and policies for possible changes. Changes to statutes, regulations or regulatory policies, including changes in interpretation or implementation of statutes, regulations or policies, could affect the Company in
 substantial and unpredictable ways. Such changes could subject the Company to additional costs, limit the types of financial services and products the Company may offer and/or limit the pricing the Company may charge on certain banking services,
 among other things. Compliance personnel and resources may increase our costs of operations and adversely impact our earnings.

 Table

 Failure to comply with laws, regulations or policies could result in sanctions by regulatory agencies, civil money penalties and/or reputation damage, which could have a material adverse effect
 on our business, financial condition and results of operations. While the Company has policies and procedures designed to prevent any such violations, there can be no assurance that such violations will not occur. See the section captioned
 "Supervision and Regulation" in Item 1. Business of this report for further information.

 We are subject to heightened regulatory requirements because we exceed $10 billion in total consolidated assets.

 As of December 31, 2023, we had total assets of approximately $13.31 billion. The Dodd-Frank Act, including the Durbin Amendment, and its implementing regulations impose enhanced supervisory
 requirements on bank holding companies with more than $10 billion in total consolidated assets. For bank holding companies with more than $10 billion in total consolidated assets, such requirements include, among other things:

 applicability of Volcker Rule requirements and restrictions;

 increased capital, leverage, liquidity and risk management standards;

 examinations by the CFPB for compliance with federal consumer financial protection laws and regulations; and

 limits on interchange fees from debit card transactions.

 The EGRRCPA, which was enacted in 2018, amended the Dodd-Frank Act to raise the $10 billion stress testing threshold to $250 billion, among other things. The federal financial regulators issued
 final rules in 2019 to increase the threshold for these stress testing requirements from $10 billion to $250 billion, consistent with the EGRRCPA.

 Our regulators will consider our compliance with these regulatory requirements that apply to us (in addition to regulatory requirements that applied to us previously) when examining our
 operations or considering any request for regulatory approval. We may, therefore, incur associated compliance costs and may be required to maintain compliance procedures.

 Failure to comply with these requirements may negatively impact the results of our operations and financial condition. To ensure compliance, we will be required to invest significant resources,
 which may necessitate hiring additional personnel and implementing additional internal controls. These additional compliance costs may have a material adverse effect on our business, results of operations and financial condition.

 Replacement of the LIBOR benchmark interest rate could adversely affect our business, financial condition, and results of operations.

 In March 2021, the United Kingdom's Financial Conduct Authority and the Intercontinental Exchange Benchmark Administration, the administrator for London Interbank Offered Rate ("LIBOR"),
 concurrently announced that certain settings of LIBOR would no longer be published on a representative basis after December 31, 2021, and the most commonly used U.S. dollar LIBOR settings would no longer be published on a representative basis after
 June 30, 2023. The Federal Reserve Board and the Federal Reserve Bank of New York organized the Alternative Reference Rates Committee, which identified the Secured Overnight Financing Rate ("SOFR") as its preferred alternative to LIBOR for use in
 derivatives and other financial contracts that are currently indexed to LIBOR.

 We had a significant number of loans, derivative contracts, borrowings and other financial instruments with attributes that were either directly or indirectly dependent on LIBOR. With the
 transition from LIBOR to SOFR as the preferred alternative to LIBOR, we have transitioned and amended our contracts and financial instruments to reference the SOFR rate where required. Since alternative rates (including SOFR) are calculated
 differently, payments under contracts referencing new rates will differ from those referencing LIBOR. The future performance of SOFR, including how changes in SOFR rates may differ from other rates during different economic conditions, cannot be
 predicted based on its limited historical performance. Further, we cannot predict how SOFR will perform in comparison to LIBOR in changing market conditions, what the effect of such rate's implementation may be on the markets for floating-rate
 financial instruments or whether such rates will be vulnerable to manipulation. The implementation of an alternative index or indices for the Company's financial arrangements may result in less predictable outcomes, including reduced or more
 volatile interest income if the alternative index or indices respond differently to market and other factors, and may result in reduced loan balances if borrowers do not accept the substitute index or indices and may result in disputes or
 litigation with customers over the appropriateness or comparability of the alternative index to LIBOR, which could have an adverse effect on the Company's results of operations.

 Our controls and procedures may fail or be circumvented, which may result in a material adverse effect on our business.

 Management regularly reviews and updates our internal controls, disclosure controls and procedures and corporate governance policies and procedures. Any system of controls, however well designed
 and operated, is based in part on certain assumptions and can provide only reasonable, not absolute, assurances that the objectives of the system are met. Any failure or circumvention of the controls and procedures or failure to comply with
 regulations related to controls and procedures could have a material adverse effect on our business, results of operations and financial condition.

 Table

 We may be held responsible for environmental liabilities with respect to properties to which we obtain title, resulting in significant financial loss.

 A significant portion of our loan portfolio at December 31, 2023 was secured by real estate. In the course of our business, we may foreclose and take title to real estate and could be subject to
 environmental liabilities with respect to these properties. We may be held liable to a government entity or to third parties for property damage, personal injury, investigation and clean-up costs incurred by these parties in connection with
 environmental contamination or may be required to clean up hazardous or toxic substances, or chemical releases at a property. The costs associated with investigation and remediation activities could be substantial. In addition, if we are the owner
 or former owner of a contaminated site, we may be subject to common law claims by third parties based on damages and costs resulting from environmental contamination emanating from the property. These costs and claims could adversely affect our
 business, results of operations, financial condition and liquidity.

 We may be adversely affected by the soundness of other financial institutions including the FHLB of New York.

 Our ability to engage in routine funding transactions could be adversely affected by the actions and commercial soundness of other financial institutions. Financial services companies are
 interrelated as a result of trading, clearing, counterparty or other relationships. We have exposure to many different industries and counterparties and we routinely execute transactions with counterparties in the financial services industry,
 including brokers and dealers, commercial banks, investment banks, mutual and hedge funds and other institutional clients. As a result, defaults by, or even rumors or questions about, one or more financial services companies, or the financial
 services industry generally, have led to market-wide liquidity problems and could lead to losses or defaults by us or by other institutions. Many of these transactions expose us to credit risk in the event of default of our counterparty or client.
 In addition, our credit risk may be exacerbated if the collateral held by us cannot be realized or is liquidated at prices not sufficient to recover the full amount of the loan or derivative exposure due us. There is no assurance that any such
 losses would not materially and adversely affect our business, financial condition or results of operations.

 The Company owns common stock of FHLB of New York in order to qualify for membership in the FHLB system, which enables it to borrow funds under the FHLB of New York's advance program. The
 carrying value and fair value of our FHLB of New York common stock was $21.6 million as of December 31, 2023. There are 11 branches of the FHLB, including New York, which are jointly liable for the consolidated obligations of the FHLB system. To
 the extent that one FHLB branch cannot meet its obligations to pay its share of the system's debt, other FHLB branches can be called upon to make the payment. Any adverse effects on the FHLB of New York could adversely affect the value of our
 investment in its common stock and negatively impact our results of operations.

 Provisions of our certificate of incorporation and bylaws, as well as Delaware law and certain banking laws, could delay or prevent a takeover of us by a
 third party.

 Provisions of the Company's certificate of incorporation and bylaws, the corporate law of the State of Delaware and state and federal banking laws, including regulatory approval requirements,
 could delay, defer or prevent a third party from acquiring the Company, despite the possible benefit to the Company's stockholders, or otherwise adversely affect the market price of the Company's common stock. These provisions include supermajority
 voting requirements for certain business combinations and advance notice requirements for nominations for election to the Company's Board of Directors and for proposing matters that stockholders may act on at stockholder meetings. In addition, the
 Company is subject to Delaware law, which among other things prohibits the Company from engaging in a business combination with any interested stockholder for a period of three years from the date the person became an interested stockholder unless
 certain conditions are met. These provisions may discourage potential takeover attempts, discourage bids for the Company's common stock at a premium over market price or adversely affect the market price of and the voting and other rights of the
 holders of the Company's common stock. These provisions could also discourage proxy contests and make it more difficult for you and other stockholders to elect directors other than candidates nominated by the Board.

 The Company has risk related to legal proceedings.

 The Company is involved in judicial, regulatory, and arbitration proceedings concerning matters arising from our business activities and fiduciary responsibilities. The Company establishes
 reserves for legal claims when payments associated with the claims become probable and the costs can be reasonably estimated. We may still incur legal costs for a matter even if a reserve is not established. In addition, the actual cost of
 resolving a legal claim may be substantially higher than any amounts reserved for that matter. The ultimate resolution of a pending or future legal proceeding, depending on the remedy sought and granted, could materially adversely affect our
 results of operations and financial condition.

 Table

 Risks Related to Cybersecurity and Data Privacy

 The Company faces operational risks and cybersecurity risks associated with incidents which have the potential to disrupt our operations, cause material
 harm to our financial condition, result in misappropriation of assets, compromise confidential information and/or damage our business relationships and cannot guarantee that the steps we and our service providers take in response to these risks
 will be effective.

 We depend upon data processing, communication systems, and information exchange on a variety of platforms and networks and over the internet to conduct business operations. In addition, we rely
 on the services of a variety of vendors to meet our data processing and communication needs. Although we require third party providers to maintain certain levels of security, such providers remain vulnerable to breaches, security incidents, system
 unavailability or other malicious attacks that could compromise sensitive information. The risk of experiencing security incidents and disruptions, particularly through cyber-attacks or cyber intrusions has generally increased as the number,
 intensity and sophistication of attempted attacks and intrusions by organized crime, hackers, terrorists, nation-states, activists and other external parties has increased. These security incidents may result in disruption of our operations;
 material harm to our financial condition, cash flows and the market price of our common stock; misappropriation of assets; compromise or corruption of confidential information; liability for information or assets stolen during the incident;
 remediation costs; increased cybersecurity and insurance costs; regulatory enforcement; litigation; and damage to our stakeholder and customer relationships.

 Moreover, in the normal course of business, we and our service providers collect and retain certain personal information provided by our customers, employees and vendors. If this information gets
 mishandled, misused, improperly accessed, lost or stolen, we could suffer significant financial, business, reputational, regulatory or other harm. These risks may increase as we continue to increase and expand our usage of web-based products and
 applications.

 These risks require continuous and likely increasing attention and resources from us to, among other actions, identify and quantify potential cybersecurity risks, and upgrade and expand our
 technologies, systems and processes to adequately address the risk. We provide on-going training for our employees to assist them in detecting phishing, malware and other malicious schemes. Such attention diverts time and resources from other
 activities and, while we have implemented policies and procedures designed to maintain the security and integrity of the information we and our service providers collect on our and their computer systems, there can be no assurance that our efforts
 will be effective. Likewise, while we have implemented security measures to prevent unauthorized access to personal information and prevent or limit the effect of possible incidents, we can provide no assurance that a security breach or disruption
 will not be successful or damaging, or, if any such breach or disruption does occur, that it can be sufficiently or timely remediated.

 Even the most well protected information, networks, systems and facilities remain potentially vulnerable because the techniques used in such attempted security breaches evolve and generally are
 not recognized until launched against a target, and in some cases are designed not to be detected and, in fact, may not be detected. Accordingly, we may be unable to anticipate these techniques or to implement adequate security barriers or other
 preventative measures, and thus it is impossible for us to entirely mitigate this risk.

 The Company may be adversely affected by fraud.

 As a financial institution, the Company is inherently exposed to operational risk in the form of theft and other fraudulent activity by employees, customers and other third parties targeting the
 Company and/or the Company's customers or data. Such activity may take many forms, including check fraud, electronic fraud, wire fraud, phishing, social engineering and other dishonest acts. Although the Company devotes substantial resources to
 maintaining effective policies and internal controls to identify and prevent such incidents, given the increasing sophistication of possible perpetrators, the Company may experience financial losses or reputational harm as a result of fraud.

 We continually encounter technological change and the failure to understand and adapt to these changes could have a material adverse impact on our business.

 The financial services industry is continually undergoing rapid technological change with frequent introductions of new technology-driven products and services. The effective use of technology
 increases efficiency and enables financial institutions to serve customers better and to reduce costs. The Company's future success depends, in part, upon its ability to address the needs of its customers by using technology to provide products and
 services that will satisfy customer demands, as well as to create additional efficiencies in the Company's operations. Many of the Company's competitors have substantially greater resources to invest in technological improvements. The Company may
 not be able to effectively implement new technology-driven products and services or be successful in marketing these products and services to its customers. Failure to successfully keep pace with technological changes affecting the financial
 services industry could have a material adverse impact on the Company's business and, in turn, the Company's financial condition and results of operations.

 Table

 Risks Related to an Investment in the Company's Securities

 There may be future sales or other dilution of the Company's equity, which may adversely affect the market price of the Company's stock.

 The Company is not restricted from issuing additional common stock, including any securities that are convertible into or exchangeable for, or that represent the right to receive, common stock.
 The Company also grants shares of common stock to employees and directors under the Company's incentive plan each year. The issuance of any additional shares of the Company's common stock or preferred stock or securities convertible into,
 exchangeable for or that represent the right to receive common stock or the exercise of such securities could be substantially dilutive to stockholders of the Company's common stock. Holders of the Company's common stock have no preemptive rights
 that entitle such holders to purchase their pro rata share of any offering of shares of any class or series. Because the Company's decision to issue securities in any future offering will depend on market conditions, its acquisition activity and
 other factors, the Company cannot predict or estimate the amount, timing or nature of its future offerings. Thus, the Company's stockholders bear the risk of the Company's future offerings reducing the market price of the Company's common stock and
 diluting their stock holdings in the Company.

 Risks Related to the Merger with Salisbury

 The merger with Salisbury could adversely affect the Company's future business and financial results.

 Despite the successful integration of Salisbury's operations with the Company's, inherent challenges persist, particularly in harmonizing operational processes, technology platforms, and
 corporate cultures. The complexity of this integration process may lead to unforeseen delays or disruptions, potentially impacting customer service quality and operational efficiency. Additionally, increased regulatory scrutiny following the merger
 could result in heightened compliance requirements and regulatory enforcement actions, posing additional risks to our business operations and financial performance. Moreover, the loss of key personnel, customer attrition, and competitive pressures
 post-merger could adversely affect the Company's ability to execute strategic initiatives and sustain growth momentum. While the Company remains committed to mitigating these risks through diligent management and proactive measures, the
 uncertainties associated with the post-merger environment necessitate ongoing vigilance and risk management efforts to safeguard our stakeholders' interests and ensure long-term success.

 General Risks

 The risks presented by acquisitions could adversely affect our financial condition and results of operations.

 The business strategy of the Company has included and may continue to include growth through acquisition. Any acquisitions (including the acquisition of Salisbury) will be accompanied by the
 risks commonly encountered in acquisitions. These risks may include, among other things:

 exposure to potential asset quality issues of the acquired business;

 potential exposure to unknown or contingent liabilities of the acquired business;

 our ability to realize anticipated cost savings;

 the difficulty of integrating operations and personnel (including the operations and personnel of Salisbury) and the potential loss of key employees;

 the potential disruption of our or the acquired company's ongoing business in such a way that could result in decreased revenues or the inability of our management to maximize
 our financial and strategic position;

 the inability to maintain uniform standards, controls, procedures and policies; and

 the impairment of relationships with the acquired company's employees and customers as a result of changes in ownership and management.

 We cannot provide any assurance that we will be successful in overcoming these risks or any other problems encountered in connection with acquisitions. Our inability to overcome these risks could
 have an adverse effect on the achievement of our business strategy and results of operations.

 We rely on our management and other key personnel, and the loss of any of them may adversely affect our operations.

 We are and will continue to be dependent upon the services of our executive management team. In addition, we will continue to depend on our ability to retain and recruit key client relationship
 managers. The unexpected loss of services of any key management personnel, or the inability to recruit and retain qualified personnel in the future, could have an adverse effect on our business and financial condition.

 ITEM 1C.

 CYBERSECURITY

 Risk Management and Strategy

 The Company maintains a cyber risk management program that is designed to identify, assess, manage, mitigate and respond to cybersecurity threats. The program addresses both the corporate information technology
 ("IT") environment and customer facing products. In line with our dedication to upholding strong corporate governance standards and safeguarding the security of our operations, we maintain a continuous effort to assess and mitigate cybersecurity
 risks that could impact our business, stakeholders and the integrity of our systems. Additionally, we maintain a similar risk-based approach to our third-party vendor management program including identifying and overseeing cybersecurity risks they
 present.

 The underlying controls of the cybersecurity program are based on recognized best practices and standards for cybersecurity and information security, including the National Institute of Standards and Technology
 ("NIST") Cybersecurity Framework ("CSF"). This framework organizes cybersecurity risks into five categories: identify, protect, detect, respond and recover. The Company regularly assesses the threat landscape of cybersecurity risks, with a layered
 defense in depth strategy that is focused on prevention and detection.

 Employing comprehensive methodologies for risk assessment, we diligently identify and evaluate potential cybersecurity threats and vulnerabilities across our systems, networks and data assets. This process involves
 regular examinations of emerging threats, conducting penetration tests, vulnerability scanning and thorough analysis of industry-specific risks. We actively participate in industry forums, information sharing initiatives and collaborate with
 relevant stakeholders to exchange threat intelligence and best practices.

 The Company continues to expand investments in Information Technology security, including additional end-user training, using layered defenses, identifying, and protecting critical assets, strengthening monitoring
 and alerting. We emphasize continuous training for our staff to improve their ability to identify and address diverse cybersecurity threats. We invest in cybersecurity technology and talent to support this endeavor. Furthermore, we conduct thorough
 reviews of our vendors and mandate specific security standards for third-party providers. Our comprehensive policies and procedures are designed to safeguard the integrity and security of information collected by us and our service providers on our
 systems. Additionally, we have implemented security measures to prevent unauthorized access to personal data and minimize the consequences of potential incidents. We consistently learn from any event and look at postmortem improvements where
 necessary to enhance our security and resilience.

 The Company consistently collaborates with third party experts to conduct audits, penetration testing, assessments and validations of our controls, aligning them with established frameworks like the NIST CFS. We
 adapt our cybersecurity policies, standards, processes and practices accordingly based on the insights provided by these reviews. These audits and assessments are useful tools for maintaining a robust cybersecurity program.

 Governance

 It is the responsibility of the Risk Management Committee ("RMC") of the Board to oversee the Company's cybersecurity risk exposures and action taken by management to monitor and mitigate cybersecurity risks.
 Cybersecurity risks are reported to the RMC at least quarterly and those reports include key performance indicators, test results, recent threats and how the Company is managing those threats, along with the effectiveness of the Information
 Security and cyber risk program. The RMC is responsible for monitoring our Information Security Program ("ISP") and is led by a member of our Board of Directors. The RMC reports quarterly to the Board regarding its activities, including those
 related to cybersecurity risk oversight. The Board receives briefings from executive management on the overall Information Security program at least annually.

 The Company has appointed the Senior Director of Information Security ("DISO") to oversee the implementation, coordination, and maintenance of the ISP. The responsibilities of the DISO include developing and
 implementing our information security program, designing appropriate administrative, technical, and physical safeguards to protect institutional data and ensuring the implementation and maintenance of safeguards across the Company as needed. The
 DISO reports to our Chief Risk Officer and has over a decade of experience leading cybersecurity oversight along with expertise in cyber-crime prevention, threat intelligence, social engineering, identity access and governance, identity theft and
 fraud prevention through prior roles in the organization. The Information Security team has cybersecurity experience or certifications, such as the Certified Information Systems Security Professional and Certified Information Security Manager from
 the Information Systems Audit and Control Association.

 The DISO also administers the Incident Response Team ("IRT") and its members, which is comprised of various high-ranking executive personnel such as the Chief Audit Officer, Chief Compliance Officer, General Counsel,
 and representatives from Technology, Operations, Accounting and Corporate Communications. Members of the NBT IRT have extensive knowledge regarding the security protocols, operational processes and IT infrastructure for the Company. This allows
 cross-functional response efforts in the detection, mitigation and prevention of a cybersecurity incident suffered by the Company or its third party service providers. Upon detection of an incident, the IRT promptly convenes and updates executive
 leadership to assess its severity level, categorizing it as low, moderate, or high. The Company actively performs simulations and tabletop exercises at a management level and incorporates external resources as needed to stay current to cyber threat
 vectors. The Incident Response Plan also maintains procedures and escalation protocol to escalate significant cybersecurity matters to the Executive Committee, RMC and/or full Board, as deemed necessary.

 Table

 During the incident response process, senior management, in collaboration with relevant personnel from information technology, information security, and, when necessary, external cybersecurity firms specializing in
 forensic investigations will assess the materiality of the breach alongside the severity scale. This evaluation aims to accurately identify risks and potential operational and business impacts. Materiality determination involves an objective
 analysis of both quantitative and qualitative factors, including an evaluation of immediate impact and reasonably likely future impacts.

 Although cybersecurity threats, including those stemming from prior incidents, have not had a significant impact on the Company in the previous fiscal year, and there are no known imminent cybersecurity threats
 likely to materially affect us, we cannot guarantee that we will remain unaffected in the future. Further, there is increasing regulation regarding responses to cybersecurity incidents, including reporting to regulators, which could subject us to
 additional liability and reputational harm. Cybersecurity threats are expected to continue to be persistent and severe. For further discussion of such risks, see the section entitled "Risk Factors" in Item 1A of this Form 10-K under the heading
 "Risks Related to Cybersecurity and Data Privacy."

 MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

 Market Information

 The common stock of the Company, par value $0.01 per share (the "Common Stock"), is quoted on the NASDAQ Global Select Market under the symbol "NBTB." The closing price of the Common Stock on
 January 31, 2024 was $35.57. As of January 31, 2024, there were 5,634 stockholders of record of Common Stock. No unregistered securities were sold by the Company during the year ended December 31, 2023.

 Stock Performance Graph

 The following stock performance graph compares the cumulative total stockholder return (i.e., price change, reinvestment of cash dividends and stock dividends received) on our Common Stock
 against the cumulative total return of the NASDAQ Stock Market (U.S. Companies) Index and the KBW Regional Bank Index (Peer Group). The stock performance graph assumes that $100 was invested on December 31, 2018. The graph further assumes the
 reinvestment of dividends into additional shares of the same class of equity securities at the frequency with which dividends are paid on such securities during the relevant fiscal year. The yearly points marked on the horizontal axis correspond to
 December 31 of that year. We calculate each of the referenced indices in the same manner. All are market-capitalization-weighted indices, so companies judged by the market to be more important (i.e., more valuable) count for more in all indices.

 Dividends

 The Company depends primarily upon dividends from subsidiaries for a substantial part of the its revenue. Accordingly, the ability to pay dividends to stockholders depends primarily upon the
 receipt of dividends or other capital distributions from the subsidiaries. Payment of dividends to the Company from the Bank is subject to certain regulatory and other restrictions. Under Office of the Comptroller of the Currency ("OCC")
 regulations, the Bank may pay dividends to the Company without prior regulatory approval so long as it meets its applicable regulatory capital requirements before and after payment of such dividends and its total dividends do not exceed its net
 income to date over the calendar year plus retained net income over the preceding two years. At December 31, 2023, the Bank was in compliance with all applicable minimum capital requirements and had the ability to pay dividends of $106.6 million to
 the Company without the prior approval of the OCC.

 If the capital of the Company is diminished by depreciation in the value of its property or by losses, or otherwise, to an amount less than the aggregate amount of the capital represented by the
 issued and outstanding stock of all classes having a preference upon the distribution of assets, no dividends may be paid out of net profits until the deficiency in the amount of capital represented by the issued and outstanding stock of all
 classes having a preference upon the distribution of assets has been repaired. See the section captioned "Supervision and Regulation" in Item 1. Business and Note 15 to the consolidated financial statements included in Item 8. Financial Statements
 and Supplementary Data, which are located elsewhere in this report.

 Stock Repurchase

 The Company purchased 155,500 shares of its common stock during year ended December 31, 2023 at an average price of $31.79 per share under its previously announced share repurchase program.
 This repurchase program under which these shares were purchased was due to expire on December 31, 2023; however, on December 18, 2023, the Board of Directors authorized and approved an amendment to the repurchase program. Pursuant to the amended
 stock repurchase program, the Company may repurchase up to 2,000,000 shares of the outstanding shares of its common stock with all repurchases under the stock repurchase program to be made by December 31, 2025. The Company may repurchase shares
 of its common stock from time to time to mitigate the potential dilutive effects of stock-based incentive plans and other potential uses of common stock for corporate purposes. The Company did not purchase any share of its common stock during the
 fourth quarter of 2023.

 Critical Accounting Policies

 Critical Accounting Policies

 The accounting and reporting policies followed by the Company conform, in all material respects, to accounting principles generally accepted in the United States of America ("GAAP") and to general practices within the financial services industry.
 In the course of normal business activity, management must select and apply many accounting policies and methodologies and make estimates and assumptions that lead to the financial results presented in the Company's consolidated financial
 statements and accompanying notes. There are uncertainties inherent in making these estimates and assumptions, which could materially affect the Company's results of operations and financial position.

 Management considers accounting estimates to be critical to reported financial results if (i) the accounting estimates require management to make assumptions about matters that are highly uncertain, and (ii) different estimates that management
 reasonably could have used for the accounting estimate in the current period, or changes in the accounting estimate that are reasonably likely to occur from period to period, could have a material impact on the Company's financial statements.
 Management considers the accounting policies relating to the allowance for credit losses ("allowance", or "ACL") and the determination of fair values for acquired assets and assumed liabilities in a business combination, including intangible
 assets such as goodwill, to be critical accounting policies because of the uncertainty and subjectivity involved in these policies and the material effect that estimates related to these areas can have on the Company's results of operations.

 The Company's methodology for estimating the allowance considers available relevant information about the collectability of cash flows, including information about past events, current conditions, and reasonable and supportable forecasts. Refer
 to Note 1 and Note 6 to the consolidated financial statements included elsewhere in this report.

 Goodwill represents the cost of the acquired business in excess of the fair value of the related net assets acquired. Following a merger, the determination of fair values for acquired assets and assumed liabilities, including intangible assets
 such as goodwill, becomes critical. All acquired assets, including goodwill and other intangible assets, and assumed liabilities in purchase acquisitions are recorded at fair value as of the acquisition date. The Company expenses all
 acquisition-related costs as incurred as required by Accounting Standards Codification ("ASC") Topic 805, "Business Combinations."

 Table

 The determination of fair values for acquired loans in a business combination is a significant aspect of our financial reporting process. The
 valuation of acquired loans relied on a discounted cash flow approach applied on a pooled basis, utilizing a forecast of principal and interest payments. This methodology segmented the acquired loan portfolio by loan type, term, interest rate,
 payment frequency and payment, and incorporated specific key valuation assumptions, encompassing prepayments, probability of default, loss given default, and the discount rate to ascertain the fair value of these assets. Given the inherent
 subjectivity and reliance on future cash flows and market conditions, this process involves considerable judgment and estimation uncertainty.

 The Company conducts an annual review of goodwill impairment and conducts quarterly analyses to identify any events that may necessitate an interim
 assessment. The Company initially undertakes a qualitative evaluation of goodwill to ascertain whether certain events or circumstances indicate a likelihood that the fair value of a reporting unit is less than its carrying amount. This
 qualitative evaluation demands considerable managerial discretion, and if it suggests that the fair value of a reporting unit is unlikely to be less than the carrying value, no quantitative analysis is required. Inputs for this qualitative
 analysis requiring managerial judgment encompass macroeconomic conditions, industry and market conditions, the financial performance of the reporting unit, and other pertinent events influencing the fair value of the reporting unit.

 For information on the Company's significant accounting policies and to gain a greater understanding of how the Company's financial performance is reported, refer to Note 1 to the consolidated financial statements included elsewhere in this
 report.

 Critical Accounting Estimates

 SEC guidance requires disclosure of "critical accounting estimates." The SEC defines "critical accounting estimates" as those estimates made in accordance with U.S. generally accepted accounting
 principles that involve a significant level of estimation uncertainty and have had or are reasonably likely to have a material impact on the financial condition or results of operations of the registrant. The Company follows financial accounting
 and reporting policies that are in accordance with GAAP. The allowance for credit losses and the allowance for unfunded commitments policies are deemed to meet the SEC's definition of a critical accounting estimate.

 Allowance for Credit Losses and Unfunded Commitments

 The allowance for credit losses consists of the allowance for credit losses and the allowance for losses on unfunded commitments. The measurement of Current Expected Credit Losses ("CECL") on financial instruments requires an estimate of the credit
 losses expected over the life of an exposure (or pool of exposures). The estimate of expected credit losses under the CECL approach is based on relevant information about past events, current conditions, and reasonable and supportable forecasts
 that affect the collectability of the reported amounts. Historical loss experience is generally the starting point for estimating expected credit losses. The Company then considers whether the historical loss experience should be adjusted for
 asset-specific risk characteristics or current conditions at the reporting date that did not exist over the period from which historical experience was used. Finally, the Company considers forecasts about future economic conditions that are
 reasonable and supportable. The allowance for credit losses for loans, as reported in our consolidated statements of financial condition, is adjusted by an expense for credit losses, which is recognized in earnings, and reduced by the charge-off of
 loan amounts, net of recoveries. The allowance for losses on unfunded commitments represents the expected credit losses on off-balance sheet commitments such as unfunded commitments to extend credit and standby letters of credit. However, a
 liability is not recognized for commitments unconditionally cancellable by the Company. The allowance for losses on unfunded commitments is determined by estimating future draws and applying the expected loss rates on those draws.

 Management of the Company considers the accounting policy relating to the allowance for credit losses to be a critical accounting estimate given the uncertainty in evaluating the level of the
 allowance required to cover management's estimate of all expected credit losses over the expected contractual life of our loan portfolio. Determining the appropriateness of the allowance is complex and requires judgment by management about the
 effect of matters that are inherently uncertain. Subsequent evaluations of the then-existing loan portfolio, in light of the factors then prevailing, may result in significant changes in the allowance for credit losses in those future periods.
 While management's current evaluation of the allowance for credit losses indicates that the allowance is appropriate, the allowance may need to be increased under adversely different conditions or assumptions. The impact of utilizing the CECL
 approach to calculate the reserve for credit losses will be significantly influenced by the composition, characteristics and quality of our loan portfolio, as well as the prevailing economic conditions and forecasts utilized. Material changes to
 these and other relevant factors may result in greater volatility to the reserve for credit losses, and therefore, greater volatility to our reported earnings.

 One of the most significant judgments involved in estimating the Company's allowance for credit losses relates to the macroeconomic forecasts used to estimate expected credit losses over the
 forecast period. As of December 31, 2023, the quantitative model incorporates a baseline economic outlook along with an alternative downside scenario sourced from a reputable third-party to accommodate other potential economic conditions in the
 model. At December 31, 2023, the weightings were 70% and 30% for the baseline and downside economic forecasts, respectively. The baseline outlook reflected an unemployment rate environment starting at 3.8% and increasing slightly during the
 forecast period to 4.1%. Northeast GDP's annualized growth (on a quarterly basis) was expected to start the first quarter of 2024 at approximately 3.7% before decreasing to a low of 2.9% in the third quarter of 2024 and then increasing to 3.8% by
 the end of the forecast period. Other utilized economic variable forecasts are mixed compared to the prior year, with retail sales up, business output mixed, and housing starts down. Key assumptions in the baseline economic outlook included
 currently being in a full employment economy, continued tapering of the Federal Reserve balance sheet, and the Federal Open Market Committee ("FOMC") beginning to cut rates in the second quarter of 2024. The alternative downside scenario assumed
 deteriorated economic conditions from the baseline outlook. Under this scenario, northeast unemployment increases to a peak of 7.0% in the first quarter of 2025. These scenarios and their respective weightings are evaluated at each measurement date
 and reflect management's expectations as of December 31, 2023. All else held equal, the changes in the weightings of our forecasted scenarios would impact the amount of estimated allowance for credit losses through changes in the quantitative
 reserve and scenario-specific qualitative adjustments. To demonstrate the sensitivity of the allowance for credit losses estimate to macroeconomic forecast weightings assumptions as of December 31, 2023, the Company attributed the change in
 scenario weightings to the change in the allowance for credit losses, with a 10% decrease to the downside scenario and a 10% increase to the baseline scenario causing a 4% decrease in the overall estimated allowance for credit losses. To further
 demonstrate the sensitivity of the allowance for credit losses estimate to macroeconomic forecast weightings assumptions as of December 31, 2023, the Company increased the downside scenario to 100% which resulted in a 26% increase in the overall
 estimated allowance for credit losses.

 Salisbury Bancorp, Inc. Merger

 On August 11, 2023, NBT completed its acquisition of Salisbury. Salisbury Bank was a Connecticut-chartered commercial bank with 13 banking offices in northwestern Connecticut, the Hudson Valley
 region of New York, and southwestern Massachusetts. In connection with the acquisition, the Company issued 4.32 million shares and acquired approximately $1.46 billion of identifiable assets, including $1.18 billion of loans, $122.7 million in
 investment securities which were sold immediately after the merger, $31.2 million of core deposit intangibles and $4.7 million in a wealth management customer intangible, as well as $1.31 billion in deposits. As of the acquisition date, the fair
 value discount was $78.7 million for loans, net of the reclassification of the purchase credit deteriorated allowance, and was $3.0 million for subordinated debt. The Company established a $14.5 million allowance for acquired Salisbury loans
 which included both the $5.8 million allowance for purchase credit deteriorated ("PCD") loans reclassified from loans and the $8.8 million allowance for non-PCD loans recognized through the provision for loan losses.

 Results of Operations

 Net income for the year ended December 31, 2023 was $118.8 million, or $2.65 per diluted common share, compared to $152.0 million, or $3.52 per diluted share, in the prior year.

 Operating net income (1), a non-GAAP measure, which excludes the impact of acquisition expenses,
 acquisition-related provision for credit losses, securities (losses) gains and an impairment of a minority interest equity investment, the Company generated $3.23 per diluted share of earnings in 2023, compared to $3.56 per diluted share in
 2022.

 The Company incurred a $4.5 million ($0.08 per diluted share) securities loss on the sale of two subordinated debt securities held in the available for sale ("AFS") portfolio
 and a $5.0 million ($0.09 per diluted share) securities loss on the write-off of a subordinated debt security of a failed financial institution.

 The Company incurred acquisition expenses of $10.0 million ($0.18 per diluted share) and $1.0 million ($0.02 per diluted share) related to the merger with Salisbury in 2023 and
 2022, respectively.

 The Company recorded a full $4.8 million ($0.08 per diluted share) impairment of its minority interest equity investment in a provider of financial and technology services to
 residential solar equipment installers due to the uncertainty in the realizability of the investment in other noninterest expense in the consolidated statements of income.

 Net interest income in 2023 increased $16.0 million in comparison to 2022, primarily due to the impact of the Salisbury acquisition.

 The Company recorded a provision for loan losses of $25.3 million ($0.44 per diluted share) in 2023, compared to $17.1 million ($0.31 per diluted share) in 2022. Included in
 the provision expense for 2023 was $8.8 million of acquisition-related provision for loan losses.

 Card services income decreased $8.2 million from prior year outcomes driven by the impact of the Company being subject to the statutory price cap provisions of the Durbin
 Amendment to the Dodd-Frank Act ("Durbin Amendment").

 2024 Outlook

 The Company's 2023 earnings reflected a continued ability to invest in the Company's future while managing through significant volatility in the interest rate environment and overall economic
 conditions which have challenged the financial services industry. Throughout 2023, the Company, along with other financial services companies, experienced lingering disruptions from the coronavirus ("COVID-19") pandemic. Mainly, the interest rate
 volatility associated with the rapid downward shift in the yield curve which remained fairly flat for the majority of 2021 and into early 2022, followed by the drastic rise in rates beginning in the second quarter of 2022, which resulted in an
 inverted yield curve for the remainder of 2022 and throughout 2023. This rate increase and curve inversion was highly correlated with a significant tightening of monetary policy to combat heightened inflation. Additionally, the three regional
 bank failures which occurred in the first quarter of 2023 resulted in heightened competition for balance sheet liquidity, which resulted in increased cost of funding as well assessment of earning asset growth capacity.

 While economic indicators have remained mixed, they have trended toward the decline of inflation. Given this decline in inflation the probability for Federal Funds rate reductions in 2024 have
 increased. This anticipated interest rate decline, coupled with strong consumer and corporate balance sheets support a view that the potential for recession has been reduced and that any form of economic slowdown could be mild. Significant items
 that may have an impact on 2024 results include:

 Excess liquidity in the banking system has significantly decreased:

 loan growth may be negatively impacted as interest rates have risen and lenders have reverted back to historical credit spreads to account for overall higher cost of funds;

 cost of deposits as well as overall cost of funds could continue to negatively impact net interest margin. While declining short term interest rates may allow
 for cost of funds reductions, the elevated level of relative interest rates and the bank failures in early 2023 continue to pressure competition for deposits as well as the associated cost of funds;

 higher short-term interest rates have continued to afford deposit customers investment opportunities outside the banking system
 resulting in deposit declines across the industry, however, a decline to short-term interest rates could potentially mitigate this;

 Investment purchases have slowed as runoff of investment cash flows have been utilized as a source of funding.

 The Federal Reserve has continued to combat elevated inflation, with the result being inflationary pressures having declined in the second half of 2023:

 this reduced inflation has had a material impact on current and expected Federal Reserve monetary policy;

 the tightening of monetary policy through measures to raise interest rates seen in 2022 and 2023 could begin to reverse itself in 2024 given softening
 inflation;

 the loosening of monetary policy through the reduction to short term interest rates in 2024 could have a negative impact on overall net interest income given
 the decline in interest rates on floating rate assets. This risk has been mitigated by the Bank's migration to a more neutral interest rate sensitivity position.

 The Company's continued focus on long-term strategies including growth in the New England markets, diversification of revenue sources, improving operating efficiencies and
 investing in technology.

 The Company's merger with Salisbury is expected to provide earnings benefit and incremental growth potential in these new markets.

 The Company's 2024 outlook is subject to factors in addition to those identified above and those risks and uncertainties that could impact the Company's future
 results are explained in Item 1A. Risk Factors.

 Table

 Asset/Liability Management

 The Company attempts to maximize net interest income and net income, while actively managing its liquidity and interest rate sensitivity through the mix of various core deposit products and
 other sources of funds, which in turn fund an appropriate mix of earning assets. The changes in the Company's asset mix and sources of funds, and the resulting impact on net interest income, on an FTE basis, are discussed below. The following
 table includes the condensed consolidated average balance sheet, an analysis of interest income/expense and average yield/rate for each major category of earning assets and interest-bearing liabilities on a taxable equivalent basis.

 Table

 2023 OPERATING RESULTS AS COMPARED TO 2022 OPERATING RESULTS

 Net Interest Income

 Net interest income for the year ended December 31, 2023 was $378.2 million, up $16.0 million, or 4.4%, from 2022. FTE net interest margin was 3.29% for the year ended
 December 31, 2023, a decrease of 5 basis points ("bps") from 2022. Interest income increased $138.7 million, or 36.1%, as the yield on average interest-earning assets increased 100 bps from 2022 to 4.54%, while average interest-earning assets of
 $11.57 billion increased $671.4 million primarily due to the Salisbury acquisition and organic loan growth partially offset by the decrease in short-term interest bearing accounts ("excess liquidity"). Interest expense was up $122.7 million, or
 560.7%, for the year ended December 31, 2023 as compared to the year ended December 31, 2022, driven by interest-bearing deposit costs increasing 140 bps to 1.56%, as well as a $404.0 million increase in the average balances of short-term
 borrowings and a 524 bps rate paid on those borrowings. The increase was also driven by the Company shifting from an excess liquidity position to an overnight borrowing position beginning in the fourth quarter of 2022. Included in net interest
 income was $4.3 million of acquisition-related net accretion, which positively impacted net interest margin by 4 bps. The Federal Reserve raised its target fed funds rate to 550 basis points in 2023, positively impacting our yields on earning
 assets.

 Loans and Corresponding Interest and Fees on Loans

 The average balance of loans increased by approximately $1.03 billion, or 13.3%, from 2022 to 2023 driven by the Salisbury acquisition and organic loan growth,
 with increases in commercial and industrial ("C&I"), commercial real estate ("CRE"), indirect auto, residential solar and residential mortgage portfolios being partly offset by a reduction in the average balance of other consumer loans. The
 yield on average loans increased from 4.28% in 2022 to 5.26% in 2023, as loans re-priced upward due to the interest rate environment in 2023. FTE interest income from loans increased 39.1%, from $333.0 million in 2022 to $463.3 million in 2023.
 This increase was due to the increases in yields and an increase in the average balance.

 Total loans were $9.65 billion and $8.15 billion at December 31, 2023 and 2022, respectively. Period end loans increased $1.50 billion or 18.4% from December 31,
 2022, which included $1.18 billion of loans acquired from Salisbury. Commercial and industrial loans increased $88.2 million to $1.35 billion; commercial real estate loans increased $819.0 million to $3.63 billion; and total consumer loans
 increased $593.4 million to $4.67 billion. Total loans represent approximately 72.5% of assets as of December 31, 2023, as compared to 69.4% as of December 31, 2022.

 Loans are summarized by business line which does not align with how the Company assesses credit risk in the estimate for credit losses under CECL.

 Loans in the C&I and CRE portfolios, consist primarily of loans made to small and medium-sized entities. The Company offers a variety of loan options to meet the specific needs of our
 commercial customers including term loans, time notes and lines of credit. Such loans are made available to businesses for working capital needs such as inventory and receivables, business expansion, equipment purchases, livestock purchases and
 seasonal crop expenses. These loans are usually collateralized by business assets such as equipment, accounts receivable and perishable agricultural products, which are exposed to industry price volatility. The Company extends CRE loans to
 facilitate various real estate transactions, encompassing acquisitions, refinancing, expansions, and enhancements to both commercial and agricultural properties. These loans are secured by liens on real estate assets, covering a spectrum of
 properties including apartments, commercial structures, healthcare facilities, and others, whether occupied by owners or non-owners. Risks associated with the CRE portfolio pertain to the borrowers' capacity to meet interest and principal
 payments throughout the loan's duration, as well as their ability to secure refinancing upon the loan's maturity. The Company has a risk management framework that includes rigorous underwriting standards, targeted portfolio stress testing,
 interest rate sensitivities on commercial borrowers and comprehensive credit risk monitoring mechanisms. The Company remains vigilant in monitoring market trends, economic indicators, and regulatory developments to promptly adapt our risk
 management strategies as needed.

 Within the CRE portfolio, approximately 78% comprises Non-Owner Occupied CRE, with the remaining 22% being Owner-Occupied CRE. Non-Owner Occupied CRE includes diverse sectors across the
 Company's markets such as apartments (33%), office spaces (17%), and construction (13%), along with retail, manufacturing, small commercial, accommodations, and others. Notably, office CRE loans account for 5% of the total outstanding loans,
 predominantly serving suburban medical and professional tenants across suburban and small urban markets. These loans carry an average size of $2.5 million, with 14% maturing over the next two years. As of December 31, 2023, the total CRE
 construction and development loans amounted to $347.2 million.

 The Company participated in the Small Business Administration's ("SBA") Paycheck Protection Program ("PPP"), a guaranteed, forgivable loan program created under the Coronavirus Aid, Relief and
 Economic Security Act ("CARES Act") and the Consolidated Appropriation Act targeted to provide small businesses with support to cover payroll and certain other expenses. Loans made under the PPP are fully guaranteed by the SBA, the guarantee is
 backed by the full faith and credit of the United States government. PPP covered loans also afford borrowers forgiveness up to the principal amount of the PPP covered loan, plus accrued interest, if the loan proceeds are used to retain workers
 and maintain payroll or to make certain mortgage interest, lease and utility payments, and certain other criteria are satisfied. The SBA will reimburse PPP lenders for any amount of a PPP covered loan that is forgiven, and PPP lenders will not be
 held liable for any representations made by PPP borrowers in connection with their requests for loan forgiveness. Lenders receive pre-determined fees for processing and servicing PPP loans. In addition, PPP loans are risk-weighted at zero percent
 under the generally applicable Standardized Approach used to calculate risk-weighted assets for regulatory capital purposes.

 Residential real estate loans consist primarily of loans secured by a first or second mortgage on primary residences. We originate adjustable-rate and fixed-rate, one-to-four-family residential
 loans for the construction or purchase of a residential property or refinancing of a mortgage. These loans are collateralized by properties located in the Company's market area. Subprime mortgage lending, which has been the riskiest sector of the
 residential housing market, is not a market that the Company has ever actively pursued. The market does not apply a uniform definition of what constitutes "subprime" lending. Our reference to subprime lending relies upon the "Statement on
 Subprime Mortgage Lending" issued by the Office of Thrift Supervision and the other federal bank regulatory agencies (the "Agencies"), on June 29, 2007, which further referenced the "Expanded Guidance for Subprime Lending Programs," or the
 Expanded Guidance, issued by the Agencies by press release dated January 31, 2001. As of December 31, 2023, there were $39.9 million in residential construction and development loans included in total loans.

 Table

 In 2017, the Company partnered with Sungage Financial, LLC. to offer financing to consumers for solar ownership with the program tailored for delivery through solar installers. Advances of
 credit through this business line are to prime borrowers and are subject to the Company's underwriting standards. Typically, the Company collects fees at origination that are deferred and recognized into interest income over the estimated life of
 the loan.

 The Company offers a variety of consumer loan products including indirect auto, home equity and other consumer loans. Indirect auto loans include indirect installment loans to individuals,
 which are primarily secured by automobiles. Although automobile loans have generally been originated through dealers, all applications submitted through dealers are subject to the Company's normal underwriting and loan approval procedures. Other
 consumer loans consist of direct installment loans to individuals most secured by automobiles and other personal property and unsecured consumer loans across a national footprint originated through our relationship with national technology-driven
 consumer lending companies that began over 10 years ago beginning with our investment in Springstone Financial LLC ("Springstone") which was subsequently acquired by LendingClub in 2014. Springstone and LendingClub loans are in a planned run-off
 status. In addition to installment loans, the Company also offers personal lines of credit, overdraft protection, home equity lines of credit and second mortgage loans (loans secured by a lien position on one-to-four family residential real
 estate) to finance home improvements, debt consolidation, education and other uses. For home equity loans, consumers are able to borrow up to 85% of the equity in their homes, and are generally tied to Prime with a ten year draw followed by a
 fifteen year amortization.

 Loans by Maturity and Interest Rate Sensitivity

 The following table presents the maturity distribution and an analysis of loans that have predetermined and floating interest rates. Scheduled repayments are reported in the maturity category
 in which the contractual maturity is due. For loans without contractual maturities, classification of maturity is consistent with the policy elections to measure the allowance for credit losses. Specifically, C&I and CRE lines of credit
 assume one year maturity for relationships over $1.0 million and five year maturity for relationships under $1.0 million, while home equity line of credits maturities are classified based on their fixed rate conversion date plus five years.
 C&I includes PPP and other consumer includes home equity and other consumer loans.

 The Company's mortgage-backed securities, U.S. agency notes and collateralized mortgage obligations are all guaranteed by Fannie Mae, Freddie Mac, FHLB, Federal Farm Credit Banks or Ginnie Mae
 ("GNMA"). GNMA securities are considered similar in credit quality to U.S. Treasury securities, as they are backed by the full faith and credit of the U.S. government. Currently, there are no subprime mortgages in the investment portfolio.

 The following tables set forth information with regard to contractual masturities of debt securities shown in amortized cost ($) and weighted average yield (%) at December 31, 2023.
 Weighted-average yields are an arithmetic computation of income (not FTE adjusted) divided by amortized cost. Maturities of mortgage-backed, collateralized mortgage obligations and asset-backed securities are stated based on their estimated
 average lives. Actual maturities may differ from estimated average lives or contractual maturities because, in certain cases, borrowers have the right to call or prepay obligations with or without call or prepayment penalties.

 Funding Sources and Corresponding Interest Expense

 The Company utilizes traditional deposit products such as time, savings, NOW, money market and demand deposits as its primary source for funding. Other sources,
 such as short-term FHLB advances, federal funds purchased, securities sold under agreements to repurchase, brokered time deposits and long-term FHLB borrowings are utilized as necessary to support the Company's growth in assets and to achieve
 interest rate sensitivity objectives. The average balance of interest-bearing liabilities totaled $7.47 billion in 2023 and increased $815.0 million from 2022. The increase was primarily driven by the interest-bearing deposits acquired from
 Salisbury and an increase in short-term borrowings. The rate paid on interest-bearing liabilities increased from 0.33% in 2022 to 1.93% in 2023. This increase in rates caused an increase in interest expense of $122.7 million, or 560.7%, from
 $21.9 million in 2022 to $144.6 million in 2023.

 Table

 Deposits

 Average interest-bearing deposits increased $375.4 million, or 5.9%, from 2022 to 2023. Average money market deposits decreased $29.5 million, or 1.2% during 2023 compared to 2022. Average NOW
 accounts decreased $23.4 million, or 1.5% during 2023 as compared to 2022. The average balance of savings accounts decreased $113.6 million, or 6.2%, during 2023 compared to 2022. The average balance of time deposits increased $542.0 million, or
 116.6%, from 2022 to 2023. The average balance of demand deposits decreased $233.3 million, or 6.3%, during 2023 compared to 2022. The Company continues to experience the migration from no interest and low interest checking and savings accounts
 into higher cost money market and time deposit instruments. The decrease in average balances was due primarily to larger commercial customers shifting balances to higher yielding investment opportunities in both the Company's wealth management
 solutions as well as other offerings in the market. The Company's composition of total deposits is diverse and granular with over 563,000 accounts with an average per account balance of $19,483 as of December 31, 2023.

 The rate paid on average interest-bearing deposits was up 140 bps to 1.56% for 2023. The rate paid for money market deposit accounts increased 238 bps to 2.58% from 2022 to 2023. The rate paid
 for NOW deposit accounts increased from 0.16% in 2022 to 0.53% in 2023. The rate paid for savings deposits increased from 0.03% in 2022 to 0.04% in 2023. The rate paid for time deposits increased from 0.38% during 2022 to 3.30% during 2023.

 Borrowings

 Average federal funds purchased increased to $24.6 million in 2023. The rate paid on federal funds purchased was 5.16% in 2023. Average repurchase agreements increased to $70.3 million in 2023
 from $69.6 million in 2022. The average rate paid on repurchase agreements increased from 0.10% in 2022 to 1.06% in 2023. Average short-term borrowings increased to $450.4 million in 2023 from $46.4 million in 2022. The average rate paid on
 short-term borrowings increased from 4.24% in 2022 to 5.24% in 2023. Average long-term debt increased from $6.6 million in 2022 to $24.2 million in 2023. The average balance of junior subordinated debt remained at $101.2 million in 2023. The
 average rate paid for junior subordinated debt in 2023 was 7.23%, up from 3.70% in 2022.

 Total short-term borrowings consist of federal funds purchased, securities sold under repurchase agreements, which generally represent overnight borrowing transactions and other short-term
 borrowings, primarily FHLB advances, with original maturities of one year or less. The Company has unused lines of credit with the FHLB and access to brokered deposits available for short-term financing. Those sources totaled approximately $2.87
 billion and $2.90 billion at December 31, 2023 and 2022, respectively. Securities collateralizing repurchase agreements are held in safekeeping by nonaffiliated financial institutions and are under the Company's control. Long-term debt, which is
 comprised primarily of FHLB advances, are collateralized by the FHLB stock owned by the Company, certain of its mortgage-backed securities and a blanket lien on its residential real estate mortgage loans.

 Table

 On June 23, 2020, the Company issued $100.0 million of 5.00% fixed-to-floating rate subordinated notes due 2030. The subordinated notes, which qualify as Tier 2 capital, bear interest at an
 annual rate of 5.00%, payable semi-annually in arrears commencing on January 1, 2021, and a floating rate of interest equivalent to the three-month Secured Overnight Financing Rate ("SOFR") plus a spread of 4.85%, payable quarterly in arrears
 commencing on October 1, 2025. The subordinated debt issuance cost of $2.2 million is being amortized on a straight-line basis into interest expense over five years. The Company repurchased $2.0 million of the subordinated notes during the year
 ended December 31, 2022 at a discount of $0.1 million.

 Subordinated notes assumed in connection with the Salisbury acquisition included $25.0 million of 3.50% fixed-to-floating rate subordinated notes due 2031. The subordinated notes, which qualify
 as Tier 2 capital, bear interest at an annual rate of 3.50%, payable quarterly in arrears commencing on June 30, 2021, and a floating rate of interest equivalent to the three-month SOFR plus a spread of 2.80%, payable quarterly in arrears
 commencing on June 30, 2026. As of the acquisition date, the fair value discount was $3.0 million.

 As of December 31, 2023 and December 31, 2022 the subordinated debt net of unamortized issuance costs and fair value discount was $119.7 million and $96.9
 million, respectively. Which will be amortized into interest expense over the expected call or maturity date.

 Noninterest income for the year ended December 31, 2023 was $142.2 million, down $13.4 million, or 8.6%, from the year ended December 31, 2022. During 2023, the Company incurred a $4.5 million securities loss on the
 sale of two subordinated debt securities held in the AFS portfolio and a $5.0 million securities loss on the write-off of a subordinated debt security of a failed financial institution. Excluding net securities (losses) gains, noninterest income
 for the year ended December 31, 2023 was $151.5 million, down $5.2 million or 3.3%, from the year ended December 31, 2022. The decrease from the prior year was driven by lower card services income from the impact
 of the statutory price cap provisions of the Durbin Amendment of approximately $8.0 million and lower retirement plan administration fees driven by a decrease in certain activity-based fees. These decreases were partially offset by an increase in
 wealth management and insurance services.

 Table

 Noninterest expense for the year ended December 31, 2023 was $341.7 million, up $37.2 million or 12.2%, from the year ended December 31, 2022. The Company incurred acquisition expenses for the
 year ended December 31, 2023 and December 31, 2022 of $10.0 million and $1.0 million, respectively, related to the merger with Salisbury. Included in other noninterest expenses for the year ended December 31, 2023, the Company recorded a $4.8
 million impairment of its minority interest equity investment in a provider of financial and technology services to residential solar equipment installers due to the uncertainty in the realizability of the investment. Excluding acquisition
 expenses and the impairment of a minority interest equity investment, noninterest expense for the year ended December 31, 2023 was $326.9 million, up $23.4 million or 7.7%, from the year ended December 31, 2022. The increase from the prior year
 was driven by higher salaries and employee benefits due to the Salisbury acquisition, increased salaries and wages including merit pay increases and higher health and welfare benefits, which were partially offset by lower levels of incentive
 compensation. In addition, the increase in technology and data services was due to continued investment in digital platforms solutions, the increase in the FDIC assessment expense was driven by the statutory increase in the FDIC assessment rate,
 increased occupancy expense was driven by the addition of Salisbury locations and other expenses were higher due to the increase in actuarially determined expense related to the Company's retirement plans.

 Income Taxes

 We calculate our current and deferred tax provision based on estimates and assumptions that could differ from the actual results reflected in income tax returns
 filed during the subsequent year. Adjustments based on filed returns are recorded when identified, which is generally in the fourth quarter of the subsequent year for U.S. federal and state provisions.

 The amount of income taxes the Company pays is subject at times to ongoing audits by U.S. federal and state tax authorities, which may result in proposed assessments. Future results may include
 favorable or unfavorable adjustments to the estimated tax liabilities in the period the assessments are proposed or resolved or when statutes of limitations on potential assessments expire. As a result, the Company's effective tax rate may
 fluctuate significantly on a quarterly or annual basis.

 On August 16, 2022, H.R. 5376, the Inflation Reduction Act ("IRA"), was signed into law. The IRA, among other things, introduced a corporate alternative minimum tax, excise tax on stock
 repurchases and a clean vehicle credit. The Company does not expect the impact to be material and will continue to monitor the impacts of the IRA on the business to determine if any future tax impacts may result from this legislation.

 Income tax expense for the year ended December 31, 2023 was $34.7 million, down $9.5 million, or 21.5%, from the year ended December 31, 2022. The effective tax rate was 22.6% in 2023 and was 22.5% in 2022.

 Risk Management – Credit Risk

 Credit risk is managed through a network of loan officers, credit committees, loan policies and oversight from senior credit officers and the Board of Directors. Management follows a policy of
 continually identifying, analyzing and grading credit risk inherent in each loan portfolio. An ongoing independent review of individual credits in the commercial loan portfolio is performed by the independent loan review function. These
 components of the Company's underwriting and monitoring functions are critical to the timely identification, classification and resolution of problem credits.

 Nonperforming assets consist of nonaccrual loans, loans over 90 days past due and still accruing, troubled loans modifications, other real estate owned ("OREO") and nonperforming securities.
 Loans are generally placed on nonaccrual when principal or interest payments become 90 days past due, unless the loan is well secured and in the process of collection. Loans may also be placed on nonaccrual when circumstances indicate that the
 borrower may be unable to meet the contractual principal or interest payments. The threshold for evaluating classified, commercial and commercial real estate loans risk graded substandard or doubtful, and nonperforming loans specifically
 evaluated for individual credit loss is $1.0 million. OREO represents property acquired through foreclosure and is valued at the lower of the carrying amount or fair value, less any estimated disposal costs.

 Total nonperforming assets were $37.9 million at December 31, 2023, compared to $21.2 million at December 31, 2022. Nonperforming loans at December 31, 2023 were $37.9 million or 0.39% of total
 loans, compared with $21.1 million or 0.26% of total loans at December 31, 2022. The increase in nonperforming assets was attributable to a diversified, multi-tenant commercial real estate development relationship that was placed into a
 nonaccrual status in the fourth quarter of 2023, in which NBT is a participant. The relationship is being actively managed and recent appraised values continue to support its carrying value, and as such, no specific reserve has been established.
 Total nonaccrual loans were $34.2 million or 0.35% of total loans at December 31, 2023, compared to $17.2 million or 0.21% of total loans at December 31, 2022. Past due loans as a percentage of total loans was 0.32% at December 31, 2023, down
 slightly from 0.33% of total loans at December 31, 2022.

 In addition to nonperforming loans discussed above, the Company has also identified approximately $87.7 million in potential problem loans at December 31, 2023 as compared to $52.0 million at
 December 31, 2022. Potential problem loans are loans that are currently performing, with a possibility of loss if weaknesses are not corrected. Such loans may need to be disclosed as nonperforming at some time in the future. Potential problem
 loans are classified by the Company's loan rating system as "substandard." The increase in potential problem loans from December 31, 2022 is primarily due to the migration of $48.2 million to substandard, partially offset by an increase of $13.5
 million in nonaccrual commercial loan balances. Management cannot predict the extent to which economic conditions may worsen or other factors, which may impact borrowers and the potential problem loans. Accordingly, there can be no assurance that
 other loans will not become over 90 days past due, be placed on nonaccrual, become troubled loans modifications or require increased allowance coverage and provision for loan losses. To mitigate this risk the Company maintains a diversified loan
 portfolio, has no significant concentration in any particular industry and originates loans primarily within its footprint.

 Table

 Allowance for Loan Losses

 Beginning January 1, 2020, the Company calculated the allowance for credit losses using current expected credit losses methodology. As a result of our January 1, 2020, adoption of CECL and its
 related amendments, our methodology for estimating the allowance for credit losses changed significantly from December 31, 2019. The Company recorded a net decrease to retained earnings of $4.3 million as of January 1, 2020 for the cumulative
 effect of adopting Accounting Standards Updates ("ASU") 2016-13. The transition adjustment included a $3.0 million impact due to the allowance for credit losses on loans, $2.8 million impact due to the allowance for unfunded commitments reserve
 and $1.5 million impact to the deferred tax asset.

 Beginning January 1, 2023, the Company adopted ASU 2022-02 Financial Instruments - CECL Losses (Topic 326): Troubled Debt Restructurings and Vintage
 Disclosures ("ASU 2022-02"), which resulted in an insignificant change to the Company's methodology for estimating the allowance for credit losses on Troubled Debt Restructurings ("TDRs") since December 31, 2022. The January 1, 2023
 decrease in allowance for credit loss on TDR loans relating to adoption of ASU 2022-02 was $0.6 million, which increased retained earnings by $0.5 million and decreased the deferred tax asset by $0.1 million.

 Management considers the accounting policy relating to the allowance for credit losses to be a critical estimate given the degree of judgment exercised in evaluating the level of the allowance
 required to estimate expected credit losses over the expected contractual life of our loan portfolio and the material effect that such judgments can have on the consolidated results of operations.

 The CECL approach requires an estimate of the credit losses expected over the life of a loan (or pool of loans). It replaces the incurred loss approach's threshold that required recognition of
 a credit loss when it was probable a loss event was incurred. The allowance for credit losses is a valuation account that is deducted from, or added to, the loans' amortized cost basis to present the net, lifetime amount expected to be collected
 on the loans. Loan losses are charged off against the allowance when management believes a loan balance is confirmed to be uncollectible. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be
 charged-off.

 Required additions or reductions to the allowance for credit losses are made periodically by charges or credits to the provision for loan losses. These are necessary to maintain the allowance
 at a level which management believes is reasonably reflective of the overall loss expected over the contractual life of the loan portfolio. While management uses available information to recognize losses on loans, additions or reductions to the
 allowance may fluctuate from one reporting period to another. These fluctuations are reflective of changes in risk associated with portfolio content and/or changes in management's assessment of any or all of the determining factors discussed
 above. Management considers the allowance for credit losses to be appropriate based on evaluation and analysis of the loan portfolio.

 Management estimates the allowance balance for credit losses using relevant available information, from internal and external sources, related to past events, current conditions, and reasonable
 and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Company historical loss experience was supplemented with peer information when there was insufficient loss data for the
 Company. Significant management judgment is required at each point in the measurement process.

 The allowance for credit losses is measured on a collective (pool) basis, with both a quantitative and qualitative analysis that is applied on a quarterly basis, when similar risk
 characteristics exist. The respective quantitative allowance for each segment is measured using an econometric, discounted probability of default and loss given default modeling methodology in which distinct, segment-specific multi-variate
 regression models are applied to multiple, probabilistically weighted external economic forecasts. Under the discounted cash flows methodology, expected credit losses are estimated over the effective life of the loans by measuring the difference
 between the net present value of modeled cash flows and amortized cost basis. After quantitative considerations, management applies additional qualitative adjustments so that the allowance for credit loss is reflective of the estimate of lifetime
 losses that exist in the loan portfolio at the balance sheet date.

 Portfolio segment is defined as the level at which an entity develops and documents a systematic methodology to determine its allowance for credit losses. Upon adoption of CECL, management
 revised the manner in which loans were pooled for similar risk characteristics. Management developed segments for estimating loss based on type of borrower and collateral which is generally based upon federal call report segmentation and have
 been combined or subsegmented as needed to ensure loans of similar risk profiles are appropriately pooled.

 Additional information about our Allowance for Loan Losses is included in Notes 1 and 6 to the consolidated financial statements as well as in the "Critical Accounting Estimates" section of the
 Management Discussion and Analysis. The Company's management considers the allowance for credit losses to be appropriate based on evaluation and analysis of the loan portfolio.

 Table

 The allowance for credit losses totaled $114.4 million at December 31, 2023, compared to $100.8 million at December 31, 2022. The allowance for credit losses as a percentage of loans was 1.19%
 at December 31, 2023, compared to 1.24% at December 31, 2022. The increase in the allowance for credit losses from December 31, 2022 to December 31, 2023 was primarily due to the $14.5 million of allowance for acquired Salisbury loans which
 included both the $5.8 million allowance for PCD loans reclassified from loans and the $8.8 million allowance for non-PCD loans recognized through the provision for loan losses.

 The allowance for credit losses was 302.05% of nonperforming loans at December 31, 2023 as compared to 478.72% at December 31, 2022. The allowance for credit losses was 334.38% of nonaccrual
 loans at December 31, 2023 as compared to 584.92% at December 31, 2022. The 2023 decline in the coverage of the allowance to nonperforming and nonaccrual loans largely relates to one nonperforming relationship that is individually evaluated for
 allowance which had no reserve established at December 31, 2023.

 The provision for loan losses was $25.3 million for the year ended December 31, 2023, compared to $17.1 million for the year ended December 31, 2022. Provision expense increased from the prior
 year primarily due to the $8.8 million of acquisition-related provision for loan losses due to the Salisbury acquisition and an increase in net charge-offs. Net charge-offs totaled $16.8 million for 2023, up from $8.3 million in 2022. Net
 charge-offs to average loans was 19 bps for 2023 compared to 11 bps for 2022.

 Allowance for Credit Losses on Off-Balance Sheet Credit Exposures

 The Company estimates expected credit losses over the contractual period in which the Company has exposure to credit risk via a contractual obligation to extend credit, unless that obligation
 is unconditionally cancellable by the Company. The allowance for losses on off-balance sheet credit exposures is adjusted as an expense in other noninterest expense. The estimate includes consideration of the likelihood that funding will occur
 and an estimate of expected credit losses on commitments expected to be funded over their estimated lives. As of December 31, 2023 and 2022, the allowance for losses on unfunded commitments totaled $5.1 million. Prior to January 1, 2020, the
 Company calculated the allowance for losses on unfunded commitments using the incurred loss methodology.

 Liquidity Risk

 Liquidity risk arises from the possibility that the Company may not be able to satisfy current or future financial commitments or may become unduly reliant on
 alternate funding sources. The objective of liquidity management is to ensure the Company can fund balance sheet growth, meet the cash flow requirements of depositors wanting to withdraw funds or borrowers needing assurance that sufficient funds
 will be available to meet their credit needs. Management's Asset Liability Committee ("ALCO") is responsible for liquidity management and has developed guidelines, which cover all assets and liabilities, as well as off-balance sheet items that
 are potential sources or uses of liquidity. Liquidity policies must also provide the flexibility to implement appropriate strategies, along with regular monitoring of liquidity and testing of the contingent liquidity plan. Requirements change as
 loans grow, deposits and securities mature and payments on borrowings are made. Liquidity management includes a focus on interest rate sensitivity management with a goal of avoiding widely fluctuating net interest margins through periods of
 changing economic conditions. Loan repayments and maturing investment securities are a relatively predictable source of funds. However, deposit flows, calls of investment securities and prepayments of loans and mortgage-related securities are
 strongly influenced by interest rates, the housing market, general and local economic conditions, and competition in the marketplace. Management continually monitors marketplace trends to identify patterns that might improve the predictability of
 the timing of deposit flows or asset prepayments.

 Table

 The primary liquidity measurement the Company utilizes is called "Basic Surplus," which captures the adequacy of its access to reliable sources of cash relative to the stability of its funding
 mix of average liabilities. This approach recognizes the importance of balancing levels of cash flow liquidity from short and long-term securities with the availability of dependable borrowing sources, which can be accessed when necessary. At
 December 31, 2023, the Company's Basic Surplus measurement was 11.6% of total assets, or $1.54 billion, as compared to the December 31, 2022 Basic Surplus of 13.2%, or $1.55 billion, and was above the Company's minimum of 5% (calculated at $665.5
 million and $587.0 million, of period end total assets as of December 31, 2023 and December 31, 2022, respectively) set forth in its liquidity policies.

 At December 31, 2023 and 2022, FHLB advances outstanding totaled $322.7 million and $443.8 million, respectively. At December 31, 2023 and 2022, the Bank had $77.0 million and $8.0 million,
 respectively, of collateral encumbered by municipal letters of credit. The Bank is a member of the FHLB system and had additional borrowing capacity from the FHLB of approximately $1.11 billion at December 31, 2023 and $1.17 billion at December
 31, 2022. In addition, unpledged securities could have been used to increase borrowing capacity at the FHLB by an additional $823.3 million and $898.1 million at December 31, 2023 and 2022, respectively, or used to collateralize other borrowings,
 such as repurchase agreements. The Company also has the ability to issue brokered time deposits and to borrow against established borrowing facilities with other banks (federal funds), which could provide additional liquidity of $2.01 billion at
 December 31, 2023 and $1.92 billion at December 31, 2022. In addition, the Bank has a "Borrower-in-Custody" program with the FRB with the addition of the ability to pledge automobile and residential solar loans as collateral. At December 31, 2023
 and 2022, the Bank had the capacity to borrow $1.02 billion and $622.7 million, respectively, from this program. The Company's internal policies authorize borrowing up to 25% of assets. Under this policy, remaining available borrowing capacity
 totaled $2.99 billion at December 31, 2023 and $2.41 billion at December 31, 2022.

 This Basic Surplus approach enables the Company to appropriately manage liquidity from both operational and contingency perspectives. By tempering the need for cash flow liquidity with reliable
 borrowing facilities, the Company is able to operate with a more fully invested and, therefore, higher interest income generating securities portfolio. The makeup and term structure of the securities portfolio is, in part, impacted by the overall
 interest rate sensitivity of the balance sheet. Investment decisions and deposit pricing strategies are impacted by the liquidity position. The Company considers its Basic Surplus position to be strong. However, certain events may adversely
 impact the Company's liquidity position in 2024. Continued increases to interest rates could result in deposit declines as depositors have alternative opportunities for yield on their excess funds. In the current economic environment, draws
 against lines of credit could drive asset growth higher. Disruptions in wholesale funding markets could spark increased competition for deposits. These scenarios could lead to a decrease in the Company's Basic Surplus measure below the minimum
 policy level of 5%. Note, enhanced liquidity monitoring was put in place to quickly respond to the changing environment during the COVID-19 pandemic including increasing the frequency of monitoring and adding additional sources of liquidity.
 While the pandemic has come to an end, this enhanced monitoring continues as rising interest rates and the recent bank failures have led to a deposit decline in the banking system and increased volatility to liquidity risk.

 At December 31, 2023, a portion of the Company's loans and securities were pledged as collateral on borrowings. Therefore, once on-balance-sheet liquidity is reduced, future growth of earning
 assets will depend upon the Company's ability to obtain additional funding, through growth of core deposits and collateral management and may require further use of brokered time deposits or other higher cost borrowing arrangements.

 Net cash flows provided by operating activities totaled $157.5 million and $183.2 million in 2023 and 2022, respectively. The critical elements of net operating cash flows include net income,
 adjusted for non-cash income and expense items such as the provision for loan losses, deferred income tax expense, depreciation and amortization and cash flows generated through changes in other assets and liabilities.

 Net cash flows used in investing activities totaled $44.2 million and $926.2 million in 2023 and 2022, respectively. Critical elements of investing activities are loan and investment securities
 transactions.

 Net cash flows used in financing activities totaled $105.4 million and $328.7 million in 2023 and 2022, respectively. The critical elements of financing activities are proceeds from deposits,
 borrowings and stock issuance. In addition, financing activities are impacted by dividends and treasury stock transactions.

 Commitments to Extend Credit

 The Company makes contractual commitments to extend credit, which include unused lines of credit, which are subject to the Company's credit approval and
 monitoring procedures. At December 31, 2023 and 2022, commitments to extend credit in the form of loans, including unused lines of credit, amounted to $2.68 billion and $2.42 billion, respectively. In the opinion of management, there are no
 material commitments to extend credit, including unused lines of credit that represent unusual risks. All commitments to extend credit in the form of loans, including unused lines of credit, expire within one year.

 Table

 Standby Letters of Credit

 The Company does not issue any guarantees that would require liability-recognition or disclosure, other than its standby letters of credit. The Company guarantees the obligations or performance
 of customers by issuing standby letters of credit to third-parties. These standby letters of credit are generally issued in support of third-party debt, such as corporate debt issuances, industrial revenue bonds and municipal securities. The risk
 involved in issuing standby letters of credit is essentially the same as the credit risk involved in extending loan facilities to customers and letters of credit are subject to the same credit origination, portfolio maintenance and management
 procedures in effect to monitor other credit and off-balance sheet products. Typically, these instruments have one year expirations with an option to renew upon annual review; therefore, the total amounts do not necessarily represent future cash
 requirements. At December 31, 2023 and 2022, outstanding standby letters of credit were approximately $44.7 million and $53.3 million, respectively. The fair value of the Company's standby letters of credit at December 31, 2023 and 2022 was not
 significant. The following table sets forth the commitment expiration period for standby letters of credit at:

 Interest Rate Swaps

 The Company records all derivatives on the consolidated balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative,
 whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and
 qualifying as a hedge of the exposure to changes in the fair value of an asset, liability or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a
 hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the
 hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow
 hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risks, even though hedge accounting does not apply or the Company elects not to apply hedge accounting.

 For derivatives designated as fair value hedges, changes in the fair value of the derivative and the hedged item related to the hedged risk are recognized in earnings. For derivatives designated
 and that qualify as cash flow hedges, changes in fair value of the cash flow hedges are reported in accumulated other comprehensive income or loss ("AOCI"). When the cash flows associated with the hedged item are realized, the gain or loss included
 in AOCI is subsequently reclassified and recognized in the consolidated statements of income.

 When the Company purchases or sells a portion of a commercial loan that has an existing interest rate swap, it may enter into a risk participation agreement to
 provide credit protection to the financial institution that originated the swap transaction should the borrower fail to perform on its obligation. The Company enters into both risk participation agreements in which it purchases credit protection
 from other financial institutions and those in which it provides credit protection to other financial institutions. Any fee paid to the Company under a risk participation agreement is in consideration of the credit risk of the counterparties and
 is recognized in the income statement. Credit risk on the risk participation agreements is determined after considering the risk rating, probability of default and loss given default of the counterparties.

 Loans Serviced for Others and Loans Sold with Recourse

 The total amount of loans serviced by the Company for unrelated third parties was approximately $856.9 million and $592.7 million at December 31, 2023 and 2022, respectively. At December 31,
 2023 and 2022, the Company had approximately $1.0 million and $0.6 million, respectively, of mortgage servicing rights. At December 31, 2023 and 2022, the Company serviced $26.4 million and $31.0 million, respectively, of agricultural loans sold
 with recourse. Due to sufficient collateral on these loans and government guarantees, no reserve is considered necessary at December 31, 2023 and 2022.

 Table

 Capital Resources

 Consistent with its goal to operate a sound and profitable financial institution, the Company actively seeks to maintain a "well-capitalized" institution in accordance with regulatory
 standards. The principal source of capital to the Company is earnings retention. The Company's and the Bank's capital measurements are in excess of both regulatory minimum guidelines and meet the requirements to be considered well-capitalized.

 The Company's primary source of funds to pay interest on trust preferred debentures and pay cash dividends to its stockholders are dividends from its subsidiaries. Various laws and regulations restrict
 the ability of banks to pay dividends to their stockholders. Generally, the payment of dividends by the Company in the future as well as the payment of interest on the capital securities will require the generation of sufficient future earnings
 by its subsidiaries.

 The Bank is also subject to regulatory restrictions on its ability to pay dividends to the Company. Under Office of the Comptroller of the Currency ("OCC")
 regulations, the Bank may not pay a dividend, without prior OCC approval, if the total amount of all dividends declared during the calendar year, including the proposed dividend, exceeds the sum of its retained net income to date during the
 calendar year and its retained net income over the preceding two years. At December 31, 2023 and 2022, approximately $106.6 million and $145.3 million, respectively, of the total stockholders' equity of the Bank was available for payment of
 dividends to the Company without approval by the OCC. The Bank's ability to pay dividends also is subject to the Bank being in compliance with regulatory capital requirements. The Bank is currently in compliance with these requirements. Under the
 State of Delaware General Corporation Law, the Company may declare and pay dividends either out of accumulated net retained earnings or capital surplus.

 Stock Repurchase Plan

 The Company purchased 155,500 shares of its common stock during the year ended December 31, 2023 at an average price of $31.79 per share under its previously announced share repurchase program.
 This repurchase program under which these shares were purchased was due to expire on December 31, 2023; however, on December 18, 2023, the Board of Directors authorized and approved an amendment to the repurchase program. Pursuant to the amended
 stock repurchase program, the Company may repurchase up to 2,000,000 shares of the outstanding shares of its common stock with all repurchases under the stock repurchase program to be made by December 31, 2025. The Company may repurchase shares
 of its common stock from time to time to mitigate the potential dilutive effect of stock-based incentive plans and other potential uses of common stock for corporate purposes. As of December 31, 2023, there were 2,000,000 shares available for
 repurchase under this plan which is set to expire on December 31, 2025. The Company purchased no shares of its common stock during the fourth quarter of 2023.

 ITEM 7A.

 QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

 Interest rate risk is the most significant market risk affecting the Company. Other types of market risk, such as foreign currency exchange rate risk and commodity price risk, do not arise in the
 normal course of the Company's business activities or are immaterial to the results of operations.

 Interest rate risk is defined as an exposure to a movement in interest rates that could have an adverse effect on the Company's net interest income. Net interest income is susceptible to interest
 rate risk to the degree that interest-bearing liabilities mature or reprice on a different basis than earning assets. When interest-bearing liabilities mature or reprice more quickly than earning assets in a given period, a significant increase in
 market rates of interest could adversely affect net interest income. Similarly, when earning assets mature or reprice more quickly than interest-bearing liabilities, falling interest rates could result in a decrease in net interest income.

 To manage the Company's exposure to changes in interest rates, management monitors the Company's interest rate risk. Management's Asset Liability Committee ("ALCO") meets monthly to review the
 Company's interest rate risk position and profitability and to recommend strategies for consideration by the Board of Directors. Management also reviews loan and deposit pricing and the Company's securities portfolio, formulates investment and
 funding strategies and oversees the timing and implementation of transactions to assure attainment of the Board's objectives in the most effective manner. Notwithstanding the Company's interest rate risk management activities, the potential for
 changing interest rates is an uncertainty that can have an adverse effect on net income.

 In managing the Company's asset/liability position, the Board and management aim to manage the Company's interest rate risk while minimizing net interest margin compression. At times, depending
 on the level of general interest rates, the relationship between long and short-term interest rates, market conditions and competitive factors, the Board and management may determine to increase the Company's interest rate risk position somewhat in
 order to increase its net interest margin. The Company's results of operations and net portfolio values remain vulnerable to changes in interest rates and fluctuations in the difference between long and short-term interest rates.

 The primary tool utilized by the ALCO to manage interest rate risk is earnings at risk modeling (interest rate sensitivity analysis). Information, such as principal balance, interest rate,
 maturity date, cash flows, next repricing date (if needed) and current rates are uploaded into the model to create an ending balance sheet. In addition, the ALCO makes certain assumptions regarding prepayment speeds for loans and mortgage related
 investment securities along with any optionality within the deposits and borrowings. The model is first run under an assumption of a flat rate scenario (e.g., no change in current interest rates) with a static balance sheet. Three additional models
 are run in which a gradual increase of 200 bps, a gradual increase of 100 bps and a gradual decrease of 200 bps takes place over a 12-month period with a static balance sheet. Under these scenarios, assets subject to prepayments are adjusted to
 account for faster or slower prepayment assumptions. Any investment securities or borrowings that have callable options embedded in them are handled accordingly based on the interest rate scenario. The resulting changes in net interest income are
 then measured against the flat rate scenario. The Company also runs other interest rate scenarios to highlight potential interest rate risk.

 The Company's Interest Rate Sensitivity has migrated to a near neutral position. In the declining rate scenario, net interest income is projected to modestly decrease when compared to the
 forecasted net interest income in the flat rate scenario through the simulation period. The decrease in net interest income is a result of earning assets repricing and rolling over at lower yields at a faster pace than interest-bearing liabilities
 decline and/or reach their floors. In the rising rate scenarios, net interest income is near neutral, impacted by slowing prepayments speeds and increased deposit reactivity; the magnitude of potential impact on earnings may be affected by the
 ability to lag deposit repricing on NOW, savings, money market deposit accounts and time accounts. Net interest income for the next twelve months in the +200/+100/-200 bp scenarios, as described above, is within the internal policy risk limits of
 not more than a 7.5% reduction in net interest income. The following table summarizes the percentage change in net interest income in the rising and declining rate scenarios over a 12-month period from the forecasted net interest income in the flat
 rate scenario using the December 31, 2023 balance sheet position:

 The Company anticipates that the trajectory of net interest income will continue to depend significantly on the timing and path of short to mid-term interest
 rates which are heavily driven by inflationary pressures and Federal Open Market Committee monetary policy. In response to the economic impact of the pandemic, the federal funds rate was reduced to near zero in March 2020, term interest rates
 fell sharply across the yield curve and the Company reduced deposit rates. Post-pandemic, inflationary pressures have resulted in a higher overall yield curve with Federal Funds increases of 425 bps in 2022 with additional 100 bps of increases in
 2023. While deposit rates have increased meaningfully in 2023 in conjunction with the increase to short term interest rates, the Company continues to focus on managing deposit expense in an environment of elevated interest rates while allowing
 assets to reprice upward.

 We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform
 the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of
 the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated
 financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our
 audits provide a reasonable basis for our opinion.

 Critical Audit Matters

 The critical audit matters communicated below are matters arising from the current period audit of the consolidated
 financial statements that were communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially
 challenging, subjective, or complex judgments. The communication of a critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit
 matters below, providing a separate opinion on the critical audit matters or on the accounts or disclosures to which they relate.

 Allowance for credit losses – loans evaluated on a collective basis

 As discussed in Notes 1 and 6 to the consolidated
 financial statements, the Company's allowance for credit losses on loans evaluated on a collective basis (the collective ACL on loans) was $114.4 million of a total allowance for credit losses of $114.4 million as of December 31, 2023. The
 collective ACL on loans includes the measure of expected credit losses on a collective (pooled) basis for class segments of loans that share similar risk characteristics. The Company uses a discounted cash flow methodology where the respective
 quantitative allowance for each segment is measured by comparing the amortized cost to the present value of expected principal, interest and recovery cash flows projected using an econometric, probability of default (PD) and loss given default
 (LGD) modeling methodology. The Company uses PD regression models to develop the PD, and LGD models to develop the LGD, using historical credit loss experience for both the Company and segment-specific selected peers. The application of these
 models incorporates multiple weighted external economic forecasts for the economic variables over the reasonable and supportable forecast period. After the reasonable and supportable forecast period, the Company reverts to long-term average
 economic variables over a reversion period on a straight-line basis. Contractual cash flows over the contractual life of the loans are the basis for expected principal, interest and recovery cash flows, adjusted for modeled defaults and expected
 prepayments and discounted at the loan-level effective interest rate. After quantitative considerations, the Company applies additional qualitative adjustments, giving consideration to the effects of limitations inherent in the quantitative
 model, so that the collective ACL is reflective of the estimate of lifetime losses that exist in the loan portfolio at the balance sheet date.

 We identified the assessment of the collective ACL on loans as a critical audit matter. A high degree of audit effort, including specialized skills and knowledge, and subjective and complex auditor judgment was involved in
 the assessment of the collective ACL on loans due to significant measurement uncertainty. Specifically, the assessment encompassed the evaluation of the collective ACL on loans methodology, including the methods and models used to estimate (1)
 the PD and LGD and their significant assumptions including the external economic forecasts and economic variables, and the related weighting of the forecasts, the reasonable and supportable forecast periods, the composition of the peer group and
 the period from which historical Company and peer experience was used, (2) the expected prepayments assumption, and (3) the qualitative adjustments and the significant assumptions, including the effects of limitations inherent in the quantitative
 model. The assessment also included an evaluation of the conceptual soundness and performance of the PD regression and LGD models. In addition, auditor judgment was required to evaluate the sufficiency of audit evidence obtained.

 The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls
 related to the Company's measurement of the collective ACL on loans estimate, including controls over the:

 •

 development of the collective ACL on loans methodology

 •

 continued use and appropriateness of changes made to the PD regression models

 •

 continued use and appropriateness of the LGD models

 •

 performance monitoring of the PD regression and LGD models

 •

 identification and determination of the expected prepayments assumption and the significant assumptions used in the PD regression and LGD models

 •

 development of the qualitative methodology and related adjustments, including the significant assumptions used in the measurement of select qualitative
 adjustments

 •

 analysis of the collective ACL on loans results, trends, and ratios.

 We evaluated the Company's process to develop the collective ACL on loans estimate by testing certain sources of data, factors, and assumptions that the Company used, and considered the relevance and reliability of such data,
 factors, and assumptions. In addition, we involved credit risk professionals with specialized skills and knowledge, who assisted in:

 •

 evaluating the Company's collective ACL on loans methodology for compliance with U.S. generally accepted accounting principles

 •

 evaluating judgments made by the Company relative to the performance monitoring of the PD regression and LGD models, by comparing them to relevant
 Company-specific metrics and trends and the applicable industry and regulatory practices

 •

 assessing the conceptual soundness and performance testing of the PD regression and LGD models, by inspecting the model documentation to determine whether
 the models are suitable for their intended use

 •

 evaluating the expected prepayments assumption by comparing to relevant Company-specific metrics and trends and current economic considerations

 •

 evaluating the selection of economic forecasts, including weighting of the forecasts, and underlying assumptions by comparing to the Company's business
 environment and relevant industry practices

 •

 evaluating the length of the period from which historical Company and peer experience was used and the reasonable and supportable forecast period by
 comparing them to specific portfolio risk characteristics and trends

 •

 assessing the composition of the peer group by comparing to Company and specific portfolio risk characteristics

 •

 evaluating the methodology used to develop the qualitative adjustments and the effect of those adjustments on the collective ACL on loans by comparing to
 relevant credit risk factors, the current economic environment and consistency with credit trends and identified limitations of the underlying quantitative models.

 We also assessed the sufficiency of the audit evidence obtained related to the collective ACL on loans estimate by evaluating the:

 •

 cumulative results of the audit procedures

 •

 qualitative aspects of the Company's accounting practices

 •

 potential bias in the accounting estimate.

 Fair
 value measurement of the acquired loans in the Salisbury Bancorp, Inc. business combination

 As
 discussed in Note 3 to the consolidated financial statements, the Company acquired Salisbury Bancorp, Inc. (Salisbury) on August 11, 2023. The transaction was accounted for as a business combination using the acquisition method of accounting.
 Accordingly, asset acquired, liabilities assumed, and consideration paid for Salisbury were recorded at the fair values at the acquisition date, including the fair value of acquired loans of $1.17 billion. The fair value of acquired loans was
 determined using a discounted cash flow methodology applied on a pooled basis that used a forecast of principal and interest payments based on certain key valuation assumptions including, probability of default, loss given default, prepayment
 rate, and discount rate.

 We
 identified the assessment of the fair value measurement of the acquired loans as a critical audit matter. A high degree of audit effort, including specialized skills and knowledge, and auditor judgment was involved in the assessment due to
 significant measurement uncertainty. Specifically, the assessment of the fair value measurement encompassed the evaluation of the key assumptions including probability of default, loss given default, prepayment rate, and discount rate.

 The
 following are the primary procedures we performed to address the critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls over the Company's fair value measurement process for acquired
 loans, including control over the determination of the key assumptions including probability of default, loss given default, prepayments, and discount rate. We involved valuation professionals with specialized skills and knowledge who assisted
 in developing an independent estimate of the fair value of the acquired loan portfolio, including developing independent assumptions utilizing market data for the loss assumptions, prepayment rate, and discount rate and comparing to the
 Company's estimate of fair value.

 Notes to Consolidated Financial Statements

 December 31, 2023 and 2022

 1. Summary of Significant Accounting Policies

 The accounting and reporting policies of NBT Bancorp Inc. ("NBT Bancorp") and its subsidiaries, NBT Bank, National Association ("NBT Bank" or the "Bank"), NBT Financial
 Services, Inc. and NBT Holdings, Inc., conform, in all material respects, with generally accepted accounting principles in the United States of America
 ("GAAP") and to general practices within the banking industry. Collectively, NBT Bancorp and its subsidiaries are referred to herein as (the "Company").

 The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the financial
 statements and accompanying notes. Actual results could differ from these estimates and such differences could be material to the financial statements.

 Estimates associated with the allowance for credit losses, pension accounting, provision for income taxes, fair values of financial instruments and status of
 contingencies are particularly susceptible to material change in the near term.

 The following is a description of significant policies and practices:

 Consolidation

 The accompanying consolidated financial statements include the accounts of NBT Bancorp and its wholly-owned subsidiaries mentioned above. All
 material intercompany transactions have been eliminated in consolidation. Amounts previously reported in the consolidated financial statements are reclassified whenever necessary to conform to the current year's presentation. In the "Parent Company
 Financial Information," the investment in subsidiaries is recorded using the equity method of accounting.

 The Company determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity or a variable
 interest entity under GAAP. Voting interest entities are entities in which the total equity investment at risk is sufficient to enable the entity to finance itself independently and provides the equity holders with the obligation to absorb losses,
 the right to receive residual returns and the right to make decisions about the entity's activities. The Company consolidates voting interest entities in which it has all, or at least a majority of, the voting interest. As defined in applicable
 accounting standards, variable interest entities ("VIEs") are entities that lack one or more of the characteristics of a voting interest entity. A controlling financial interest in a VIE is present when the Company has both the power and ability to
 direct the activities of the VIE that most significantly impact the VIE's economic performance and an obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. The Company's wholly-owned
 subsidiaries CNBF Capital Trust I, NBT Statutory Trust I, NBT Statutory Trust II, Alliance Financial Capital Trust I and Alliance Financial Capital Trust II are VIEs for which the Company is not the primary beneficiary. Accordingly, the accounts of
 these entities are not included in the Company's consolidated financial statements.

 Segment Reporting

 The Company's operations are primarily in the community banking industry and include the provision of traditional banking services. The Company also provides other
 services through its subsidiaries such as insurance, retirement plan administration and trust administration. The Company operates in the geographical regions of upstate New York, northeastern Pennsylvania, southern New Hampshire, western
 Massachusetts, Vermont, southern Maine and central and northwestern Connecticut. The Company has no reportable operating segments.

 Cash Equivalents

 The Company considers amounts due from correspondent banks, cash items in process of collection and institutional money market mutual funds to be cash equivalents for
 purposes of the consolidated statements of cash flows.

 Table

 Securities

 The Company classifies its securities at date of purchase as either held to maturity ("HTM"), available for sale ("AFS") or equity. HTM debt securities are those that
 the Company has the ability and intent to hold until maturity. AFS debt securities are securities that are not classified as HTM. AFS securities are recorded
 at fair value. Unrealized holding gains and losses, net of the related tax effect, on AFS securities are excluded from earnings and are reported in the consolidated statements of changes in stockholders' equity and the consolidated statements of
 comprehensive income (loss) as a component of accumulated other comprehensive income (loss) ("AOCI"). HTM securities are recorded at amortized cost. Transfers of securities between categories are recorded at fair value at the date of transfer.
 Non-marketable equity securities and equity securities without readily determinable fair values are carried at cost. The Company performs a qualitative assessment on equity securities to determine whether the investments are impaired and downward or
 upward adjustments are recognized through the income statement. All other equity securities are recorded at fair value, with net unrealized gains and losses recognized in income.

 Premiums and discounts are amortized or accreted over the life of the related security as an adjustment to yield using the interest method. Dividend and interest income
 are recognized when earned. Realized gains and losses on securities sold are derived using the specific identification method for determining the cost of securities sold.

 Allowance for Credit Losses – HTM Debt Securities

 With respect to its HTM debt securities, the Company is required to utilize the Financial Accounting Standards Board ("FASB") Accounting Standards
 Update ("ASU") 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("CECL") approach to estimate
 expected credit losses. Management measures expected credit losses on HTM debt securities on a collective basis by major security types that share similar risk characteristics, such as (as applicable): internal or external (third-party) credit score
 or credit ratings, risk ratings or classification, financial asset type, collateral type, size, effective interest rate, term, geographical location, industry of the borrower, vintage, historical or expected credit loss patterns, and reasonable and
 supportable forecast periods. Management classifies the HTM portfolio into the following major security types: U.S. government agency or U.S. government-sponsored mortgage-backed and collateralized mortgage obligations securities, and state and
 municipal debt securities.

 The HTM mortgage-backed and collateralized mortgage obligations securities are issued by U.S. government entities and agencies. These securities are
 either explicitly and/or implicitly guaranteed by the U.S. government as to timely repayment of principal and interest, are highly rated by major rating agencies, and have a long history of zero credit losses. Therefore, the Company did not record an
 allowance for credit loss for these securities.

 State and municipal bonds generally carry a Moody's rating of A to AAA. In addition, the Company has a limited amount of New York state local
 municipal bonds that are not rated. The estimate of expected credit losses on the HTM portfolio is based on the expected cash flows of each individual bond over its contractual life and considers historical credit loss information, current conditions
 and reasonable and supportable forecasts. Given the rarity of municipal defaults and losses, the Company utilized Moody's Municipal Loss Forecast Model as the sole source of municipal default and loss rates which provides decades of data across all
 municipal sectors and geographies. As with the loan portfolio, cash flows are forecast over a 6-quarter period under various weighted economic conditions, with a reversion to long-term average economic conditions over a 4-quarter period on a
 straight-line basis. Management may exercise discretion to make adjustments based on environmental factors. The Company determined that the expected credit loss on its HTM municipal bond portfolio was immaterial and therefore no allowance for credit losses was recorded.

 Allowance for Credit Losses – AFS Debt Securities

 The impairment model for AFS debt securities differs from the CECL approach utilized for HTM debt securities because AFS debt securities are
 measured at fair value rather than amortized cost. For AFS debt securities in an unrealized loss position, the Bank first assesses whether it intends to sell, or it is more likely than not that it will be required to sell the security before recovery
 of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security's amortized cost basis is written down to fair value through income. For AFS debt securities that do not meet the aforementioned
 criteria, in making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, adverse conditions specifically related to the security, failure of
 the issuer of the debt security to make scheduled interest or principal payments, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to
 the amortized cost basis of the security. The cash flows should be estimated using information relevant to the collectability of the security, including information about past events, current conditions and reasonable and supportable forecasts. If
 the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the
 amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income.

 Investments in Federal Reserve Bank and Federal Home Loan Bank ("FHLB") stock are required for membership in those organizations and are carried at cost since there is
 no market value available. The FHLB New York continues to pay dividends and repurchase stock. As such, the Company has not recognized any impairment on its holdings of Federal Reserve Bank and FHLB stock.

 Loan Held for Sale and Loan Servicing

 Loans held for sale are recorded at the lower of cost or fair value on an individual basis. Loan sales are recorded when the sales are funded. Gains and losses on sales
 of loans held for sale are included in other noninterest income in the consolidated statements of income. Mortgage loans held for sale are generally sold with servicing rights retained. Mortgage servicing rights are recorded at fair value upon sale
 of the loan, and are amortized in proportion to and over the period of estimated net servicing income.

 Table

 Loans

 Loans are recorded at their current unpaid principal balance, net of unearned income and unamortized loan fees and expenses, which are amortized under the effective
 interest method over the estimated lives of the loans. Interest income on loans is accrued based on the principal amount outstanding.

 For all loan classes within the Company's loan portfolio, loans are placed on nonaccrual status when timely collection of principal and/or interest in accordance with
 contractual terms is in doubt. Loans are transferred to nonaccrual status generally when principal or interest payments become over ninety days
 delinquent, unless the loan is well secured and in the process of collection, or sooner when management concludes circumstances indicate that borrowers may be unable to meet contractual principal or interest payments. When a loan is transferred to a
 nonaccrual status, all interest previously accrued in the current period but not collected is reversed against interest income in that period. Interest accrued in a prior period and not collected is charged-off against the allowance for credit
 losses.

 If ultimate repayment of a nonaccrual loan is expected, any payments received are applied in accordance with contractual terms. If ultimate repayment of principal is not
 expected, any payment received on a nonaccrual loan is applied to principal until ultimate repayment becomes expected. For all loan classes within the Company's loan portfolio, nonaccrual loans are returned to accrual status when they become current
 as to principal and interest and demonstrate a period of performance under the contractual terms and, in the opinion of management, are fully collectible as to principal and interest. For loans in all portfolios, the principal amount is charged off
 in full or in part as soon as management determines, based on available facts, that the collection of principal in full or in part is improbable. For Commercial loans, management considers specific facts and circumstances relative to individual
 credits in making such a determination. For Consumer and Residential loan classes, management uses specific guidance and thresholds from the Federal Financial Institutions Examination Council's Uniform Retail Credit Classification and Account
 Management Policy.

 Beginning in 2023, with the Company's adoption of ASU 2022-02, Financial Instru ments - CECL Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures ("ASU 2022-02"), the recognition of a troubled debt restructuring ("TDR") was
 eliminated and instead the Company evaluates borrowers who are experiencing financial difficulty or loan modifications to borrowers experiencing financial difficulties. When a borrower is experiencing financial difficulties and the Company modifies
 a loan, such modifications generally include one or a combination of the following: an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk; a change in scheduled payment
 amount; or principal forgiveness. Modifications to borrowers experiencing financial difficulty may be different from those previously disclosed in TDR disclosures since the Company is no longer required to determine if a concession has been
 granted, which was a requirement to determine whether a loan modification was considered to be a TDR. Historically, a TDR would generally include one or a
 combination of the following: an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk; a temporary reduction in the interest rate; or a change in scheduled payment amount. TDR
 loans were nonaccrual loans; however, they could be returned to accrual status after a period of performance, generally evidenced by six months
 of compliance with their modified terms.

 Allowance for Credit Losses - Loans

 The CECL approach requires an estimate of the credit losses expected over the life of a loan (or pool of loans). The allowance for credit losses is
 a valuation account that is deducted from, or added to, the loans' amortized cost basis to present the net, lifetime amount expected to be collected on the loans. Loan losses are charged off against the allowance when management believes a loan
 balance is confirmed to be uncollectible. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off.

 Management estimates the allowance balance for credit losses using relevant information, from internal and external sources, related to past events,
 current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts. Historical loss experience is generally the starting point for estimating expected credit losses. The Company then considers whether
 the historical loss experience should be adjusted for asset-specific risk characteristics or current conditions at the reporting date that did not exist over the period from which historical experience is used. Adjustments to historical loss
 information is made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency level or term as well as changes in environmental conditions, such as changes in unemployment
 rates, production metrics, property values, or other relevant factors. Company historical loss experience is supplemented with peer information when there is insufficient loss data for the Company. Peer selection is based on a review of institutions
 with comparable loss experience as well as loan yield, bank size, portfolio concentration and geography. Finally, the Company considers forecasts about future economic conditions that are reasonable and supportable. Significant management judgment is
 required at various points in the measurement process.

 Portfolio segment is defined as the level at which an entity develops and documents a systematic methodology to determine its allowance for credit
 losses. Upon adoption of CECL, management revised the manner in which loans were pooled for similar risk characteristics. Management developed segments for estimating loss based on type of borrower and collateral which is generally based upon federal
 call report segmentation and have been combined or subsegmented as needed to ensure loans of similar risk profiles are appropriately pooled.

 Table

 During 2023, the Company made adjustments to the class segments within the portfolios to better align risk characteristics and reflect the
 monitoring and assessment of risks as the portfolios continue to evolve. Paycheck Protection Program was consolidated with Commercial & Industrial, as the portfolio had decreased to less than $ 1 million and no longer warranted a material class segment. The Other Consumer class segment was further separated into Residential Solar and Other Consumer. The growth in our
 Residential Solar loans warranted evaluation of this class separately from the Other Consumer class segments. The change to the class segments was applied retrospectively and did not have a significant impact on the allowance for loan losses. The following
 table illustrates the portfolio and class segments for the Company's loan portfolio:

 Portfolio Segment

 Class

 Commercial Loans

 Commercial & Industrial

 Commercial Real Estate

 Consumer Loans

 Auto

 Residential Solar

 Other Consumer

 Residential Loans

 Commercial Loans

 The Company offers a variety of commercial loan products. The Company's underwriting analysis for commercial loans typically includes credit
 verification, independent appraisals, a review of the borrower's financial condition and a detailed analysis of the borrower's underlying cash flows.

 Commercial and Industrial ("C&I") – The Company offers
 a variety of loan options to meet the specific needs of our C&I customers including term loans, time notes and lines of credit. Such loans are made available to businesses for working capital needs and are typically collateralized by business
 assets such as equipment, accounts receivable and perishable agricultural products, which are exposed to industry price volatility. To reduce these risks, management also attempts to obtain personal guarantees of the owners or to obtain government
 loan guarantees to provide further support.

 Commercial Real Estate ("CRE") – The Company offers CRE
 loans to finance real estate purchases, refinancing's, expansions and improvements to commercial and agricultural properties. CRE loans are loans that are secured by liens on real estate, which may include both owner-occupied and nonowner-occupied
 properties, such as apartments, commercial structures, health care facilities and other facilities. The Company's underwriting analysis includes credit verification, independent appraisals, a review of the borrower's financial condition and a
 detailed analysis of the borrower's underlying cash flows. These loans are typically originated in amounts of no more than 80 % of the
 appraised value of the property. Government loan guarantees may be obtained to provide further support for agricultural property.

 Consumer Loans

 The Company offers a variety of Consumer loan products including Auto, Residential Solar and Other Consumer loans.

 Auto – The Company provides both direct and indirect
 financing of automobiles ("Auto"). The Company maintains relationships with many dealers primarily in the communities that we serve. Through these relationships, the Company primarily finances the purchases of automobiles indirectly through dealer
 relationships. Auto loans are secured with collateral consisting of a perfected lien on the vehicle being purchased. Most of these loans carry a fixed rate of interest with principal repayment terms typically ranging from three to six years, based upon the nature
 of the collateral and the size of the loan.

 Solar – The Company offers loans across a national
 footprint originated through our relationships with national technology-driven consumer lending companies to finance the purchase and installation of residential solar energy. Advances of credit through this business line are subject to the
 Company's underwriting standards including criteria such as FICO score and debt to income thresholds. In 2017, the Company partnered with Sungage Financial, LLC. to offer financing to consumers for solar ownership with the program tailored for
 delivery through solar installers. Advances of credit through this business line are to prime borrowers and are subject to the Company's underwriting standards. Residential solar loans carry a fixed rate of interest with principal repayment terms
 typically ranging from five to twenty-five
 years. Typically, the Company collects origination fees that are deferred and recognized into interest income over the estimated life of the loan.

 Other Consumer – The Other Consumer loan segment consists primarily of unsecured consumer loans and direct consumer loans. The Company offers unsecured consumer loans across a national footprint originated through our relationships with
 national technology-driven consumer lending companies to finance such things as dental and medical procedures, K-12 tuition and other consumer purpose loans. Advances of credit through this business line are subject to the Company's underwriting
 standards including criteria such as FICO score and debt to income thresholds. Advances of credit through this business line are to prime borrowers and are subject to the Company's underwriting standards. Typically, the Company collects
 origination fees that are deferred and recognized into interest income over the estimated life of the loan. The Company offers a variety of direct consumer installment loans to finance various personal expenditures. In addition to installment
 loans, the Company also offers personal lines of credit, overdraft protection, debt consolidation, education and other uses. Direct consumer installment loans carry a fixed rate of interest with principal repayment terms typically ranging from one to fifteen years, based upon the
 nature of the collateral and the size of the loan. Consumer installment loans are often secured with collateral consisting of a perfected lien on the asset being purchased or a perfected lien on a consumer's deposit account. Risk is reduced
 through underwriting criteria, which include credit verification, appraisals, a review of the borrower's financial condition and personal cash flows. A security interest, with title insurance when necessary, is taken in the underlying real
 estate.

 Table

 Residential loans consist primarily of loans secured by a first or second mortgage on primary residences, home equity loans and lines of credit in
 first and second lien positions and residential construction loans. We originate adjustable-rate and fixed rate, one-to-four-family residential loans for the construction or purchase of a residential property or the refinancing of a mortgage. These
 loans are collateralized by properties located in the Company's market area. Loans on one-to-four-family residential are generally originated in amounts of no more than 85 % of the purchase price or appraised value (whichever is lower) or have private mortgage insurance. Mortgage title insurance and hazard insurance are normally required. Construction loans have a unique risk because
 they are secured by an incomplete dwelling. This risk is reduced through periodic site inspections, including one at each loan draw period. For home equity loans, consumers are able to borrow up to 85 % of the equity in their homes and are generally tied to Prime with a ten-year
 draw followed by a fifteen-year amortization. These loans carry a higher risk than first mortgage residential loans as they are often in a
 second position with respect to collateral.

 Historical credit loss experience for both the Company and segment-specific peers provides the basis for the estimation of expected credit losses,
 where observed credit losses are converted to probability of default rate ("PD") curves through the use of segment-specific loss given default ("LGD") risk factors that convert default rates to loss severity based on industry-level, observed
 relationships between the two variables for each asset class, primarily due to the nature of the underlying collateral. These risk factors were assessed for reasonableness against the Company's own loss experience and adjusted in certain cases when
 the relationship between the Company's historical default and loss severity deviated from that of the wider industry. The historical PD curves, together with corresponding economic conditions, establish a quantitative relationship between economic
 conditions and loan performance through an economic cycle.

 Using the historical relationship between economic conditions and loan performance, management's expectation of future loan performance is
 incorporated using externally developed economic forecasts which are probabilistically weighted to reflect potential forecast inaccuracy and model limitations. These forecasts are applied over a period that management has determined to be reasonable
 and supportable. Beyond the period over which management can develop or source a reasonable and supportable forecast, the model will revert to long-term average economic conditions using a straight-line, time-based methodology.

 The allowance for credit losses is measured on a collective (pool) basis, with both a quantitative and qualitative analysis that is applied on a
 quarterly basis, when similar risk characteristics exist. The respective quantitative allowance for each segment is measured using an econometric, PD/LGD modeling methodology in which distinct, segment-specific multi-variate regression models are
 applied to multiple, probabilistically weighted external economic forecasts. Under the discounted cash flows methodology, expected credit losses are estimated over the effective life of the loans by measuring the difference between the net present
 value of modeled cash flows and amortized cost basis. Contractual cash flows over the contractual life of the loans are the basis for modeled cash flows, adjusted for modeled defaults and expected prepayments and discounted at the loan-level stated
 interest rate. The contractual term excludes expected extensions, renewals, and modifications unless the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by
 the Company.

 After quantitative considerations, management applies additional qualitative adjustments so that the allowance for credit losses is reflective of
 the estimate of lifetime losses that exist in the loan portfolio at the balance sheet date. Qualitative considerations include limitations inherent in the quantitative model; trends experienced in nonperforming and delinquent loans; changes in value
 of underlying collateral; changes in lending policies and procedures; nature and composition of loans; portfolio concentrations that may affect loss experience across one or more components of the portfolio; the experience, ability and depth of
 lending management and staff; the Company's credit review system; and the effect of external factors; such as competition, legal and regulatory requirements.

 The threshold for evaluating classified, commercial and commercial real estate loans risk graded substandard or doubtful, and nonperforming loans
 specifically evaluated for individual credit loss is $ 1.0 million. When management determines that foreclosure is probable, expected credit
 losses are based on the fair value of the collateral at the reporting date, adjusted for selling costs as appropriate. If the loan is not collateral dependent, the allowance for credit losses related to individually assessed loans is based on
 discounted expected cash flows using the loan's initial effective interest rate. Generally, individually assessed loans are collateral dependent.

 Table

 Allowance for Credit Losses on Off-Balance Sheet Credit Exposures

 The Company estimates expected credit losses over the contractual period in which the Company has exposure to credit risk via a contractual
 obligation to extend credit, unless that obligation is unconditionally cancellable by the Company. The allowance for credit losses on off-balance sheet credit exposures is adjusted as an expense in other noninterest expense. The estimate includes
 consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over their estimated lives. Estimating credit losses on unfunded commitments requires the Bank to consider the
 following categories of off-balance sheet credit exposure: unfunded commitments to extend credit, unfunded lines of credit and standby letters of credit. Each of these unfunded commitments is then analyzed for a probability of funding to calculate a
 probable funding amount. The life of loan loss factor by related portfolio segment from the loan allowance for credit loss calculation is then applied to the probable funding amount to calculate a reserve on unfunded commitments.

 Accrued Interest Receivable

 Accrued interest receivable balances are included in other assets on the consolidated balance sheets. The Company has excluded interest receivable
 that is included in amortized cost of financing receivables from related disclosure requirements and accrued interest receivable is written off by reversing interest income. For loans, write off typically occurs upon becoming over 90 to 120 days past due and therefore the
 amount of such write offs are immaterial. Historically, the Company has not experienced uncollectible accrued interest receivable on investment securities.

 Premises and Equipment

 Premises and equipment are stated at cost, less accumulated depreciation. Depreciation of premises and equipment is determined using the straight-line method over the
 estimated useful lives of the respective assets. Expenditures for maintenance, repairs and minor replacements are charged to expense as incurred.

 Leases

 The Company determines if a lease is present at the inception of an agreement. Right-of-use ("ROU") assets and lease liabilities are recognized at lease commencement
 based on the present value of the remaining lease payments using a discount rate that represents the Company's incremental borrowing rate at the lease commencement date. ROU assets and operating lease liabilities, are included in other assets and
 other liabilities, respectively, on the consolidated balance sheets. Leases with original terms of 12 months or less are recognized in profit or loss on a
 straight-line basis over the lease term.

 Operating lease ROU assets represent the Company's right to use an underlying asset during the lease term and operating lease liabilities represent our obligation to
 make lease payments arising from the lease. ROU assets are further adjusted for lease incentives. Operating lease expense, which is comprised of amortization of the ROU asset and the implicit interest accreted on the operating lease liability, is
 recognized on a straight-line basis over the lease term, and is recorded in occupancy expense in the consolidated statements of income.

 The Company has lease agreements with lease and non-lease components, which are generally accounted for separately. For real estate leases, non-lease components and
 other non-components, such as common area maintenance charges, real estate taxes and insurance are not included in the measurement of the lease liability since they are generally able to be segregated. Our leases relate primarily to office space and
 bank branches, and some contain options to renew the lease. These options to renew are generally not considered reasonably certain to exercise, and are therefore not included in the lease term until such time that the option to renew is reasonably
 certain.

 Other Real Estate Owned

 Other real estate owned ("OREO") consists of properties acquired through foreclosure or by acceptance of a deed in lieu of foreclosure. These assets are recorded at the
 lower of fair value of the asset acquired less estimated costs to sell or "cost" (defined as the fair value at initial foreclosure). At the time of foreclosure, or when foreclosure occurs in-substance, the excess, if any, of the loan over the fair
 market value of the assets received, less estimated selling costs, is charged to the allowance for loan losses and any subsequent valuation write-downs are charged to other expense. In connection with the determination of the allowance for loan
 losses and the valuation of OREO, management obtains appraisals for properties. Operating costs associated with the properties are charged to expense as incurred. Gains on the sale of OREO are included in income when title has passed and the sale has
 met the minimum down payment requirements prescribed by GAAP. The balance of OREO is recorded in other assets on the consolidated balance sheets.

 Table

 Goodwill and Other Intangible Assets

 Goodwill represents the cost of acquired business in excess of the fair value of the related net assets acquired. Goodwill is not amortized but tested at the reporting
 unit level for impairment on an annual basis and on an interim basis or when events or circumstances dictate. The Company has elected June 30 as the annual impairment testing date for the insurance and retirement services reporting units and December
 31 for the Bank reporting unit.

 The Company has the option to first assess qualitative factors, by performing a qualitative analysis, to determine whether the existence of events or circumstances leads
 to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the events or circumstances, the Company determines it is more likely than not that the fair value of a
 reporting unit is greater than its carrying amount, the impairment test is not required. If the Company concludes otherwise, the Company is required to perform a quantitative impairment test. In the quantitative impairment test, the estimated fair
 value of a reporting unit is compared to the carrying amount in order to determine if impairment is indicated. If the estimated fair value exceeds the carrying amount, the reporting unit is not deemed to be impaired. If the estimated fair value is
 below the carrying value of the reporting unit, the difference is the amount of impairment.

 Intangible assets that have indefinite useful lives are not amortized, but are tested at least annually for impairment. Intangible assets that have finite useful lives
 are amortized over their useful lives. Core deposit intangibles and trust intangibles at the Company are amortized using the sum-of-the-years'-digits method. Covenants not to compete are amortized on a straight-line basis. Customer lists are
 amortized using an accelerated method. When facts and circumstances indicate potential impairment of amortizable intangible assets, the Company evaluates the recoverability of the asset carrying value, using estimates of undiscounted future cash
 flows over the remaining asset life. Any impairment loss is measured by the excess of carrying value over fair value.

 Determining the fair value of a reporting unit under the goodwill impairment tests and determining the fair value of other intangible assets are judgmental and often
 involve the use of significant estimates and assumptions. Estimates of fair value are primarily determined using the discounted cash flows method, which uses significant estimates and assumptions including projected future cash flows, discount rates
 reflecting the market rate of return and projected growth rates. Future events may impact such estimates and assumptions and could cause the Company to conclude that our goodwill or intangible assets have become impaired, which would result in
 recording an impairment loss.

 Bank Owned Life Insurance

 The Bank has purchased life insurance policies on certain employees, key executives and directors. Bank owned life insurance is recorded at the amount that can be
 realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.

 Treasury Stock

 Treasury stock acquisitions are recorded at cost. Subsequent sales of treasury stock are recorded on an average cost basis. Gains on the sale of treasury stock are
 credited to additional paid-in-capital. Losses on the sale of treasury stock are charged to additional paid-in-capital to the extent of previous gains, otherwise charged to retained earnings.

 Income Taxes

 Income taxes are accounted for under the asset and liability method. Deferred income taxes are recognized for the future tax consequences attributable to differences
 between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which
 those temporary differences are expected to be recovered or settled. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance, if needed, reduces deferred tax
 assets to the amount expected to be realized. The realization of deferred tax assets is primarily dependent upon the generation of adequate future taxable income. The Company recognizes interest accrued and penalties related to unrecognized tax
 benefits in income tax expense.

 Tax positions are recognized as a benefit only if it is "more likely than not" that the tax position would be sustained in a tax examination, with a tax examination
 being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50 percent likely of being realized on examination. For tax positions not meeting the "more likely than not" test, no tax benefit is recorded.

 Pension Costs

 The Company has a qualified, noncontributory, defined benefit pension plan covering substantially all of its employees, as well as supplemental employee retirement plans
 to certain current and former executives and a defined benefit postretirement healthcare plan that covers certain employees. Costs associated with these plans, based on actuarial computations of current and future benefits for employees, are charged
 to current operating expenses.

 Table

 Stock-Based Compensation

 The Company maintains various long-term incentive stock benefit plans under which restricted stock units are granted to certain directors and key
 employees. Compensation expense is recognized in the consolidated statements of income over the requisite service period, based on the grant-date fair value of the award. For restricted stock units, compensation expense is recognized ratably over the
 vesting period for the fair value of the award, measured at the grant date.

 Earnings Per Share

 Basic earnings per share ("EPS") excludes dilution and is computed by dividing income available to common stockholders by the weighted average number of common shares
 outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared
 in the earnings of the entity (such as the Company's dilutive stock options and restricted stock units).

 Comprehensive Income (Loss)

 At the Company, comprehensive income (loss) represents net income plus OCI, which consists primarily of the net change in unrealized gains (losses) on AFS debt
 securities for the period, changes in the funded status of employee benefit plans and unrealized gains (losses) on derivatives designated as hedging instruments. AOCI represents the net unrealized gains (losses) on AFS debt securities, the previously
 unrecognized portion of the funded status of employee benefit plans and the fair value of instruments designated as hedging instruments, net of income taxes, as of the consolidated balance sheet dates.

 Derivative Instruments and Hedging Activities

 The Company records all derivatives on the consolidated balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended
 use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives
 designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and
 qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss
 recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions
 in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risks, even though hedge accounting does not apply or the Company elects not to apply hedge accounting.

 For derivatives designated as fair value hedges, changes in the fair value of the derivative and the hedged item related to the hedged risk are
 recognized in earnings. For derivatives designated as cash flow hedges, changes in fair value of the cash flow hedges are reported in OCI. When the cash flows associated with the hedged item are realized, the gain or loss included in OCI is
 recognized in the consolidated statements of income.

 When the Company purchases or sells a portion of a commercial loan that has an existing interest rate swap, it may enter into a risk participation agreement to provide credit protection to the financial institution that originated the swap transaction should the borrower fail to perform on its obligation. The Company enters
 into both risk participation agreements in which it purchases credit protection from other financial institutions and those in which it provides credit protection to other financial institutions. Any fee paid to the Company under a risk
 participation agreement is in consideration of the credit risk of the counterparties and is recognized in the income statement. Credit risk on the risk participation agreements is determined after considering the risk rating, probability of default
 and loss given default of the counterparties.

 Business Combinations

 Business

 combinations are accounted for under the acquisition method of accounting. Acquired assets, including separately identifiable intangible assets, and assumed liabilities are recorded at their acquisition date estimated fair values. The excess of
 the cost of acquisition over these fair values is recognized as goodwill. During the measurement period, which cannot exceed one year from the acquisition date, changes to estimated fair values are recognized as an adjustment to goodwill.
 Certain transaction costs are expensed as incurred. See Note 3 for additional information.

 Table

 Fair Value Measurements

 GAAP states that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction
 between market participants. Fair value measurements are not adjusted for transaction costs. A fair value hierarchy exists within GAAP that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest
 priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:

 Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted
 assets or liabilities;

 Level 2 - Quoted prices for similar assets or liabilities in active markets, quoted prices in markets that are not active or inputs that are observable, either directly
 or indirectly, for substantially the full term of the asset or liability; and

 Level 3 - Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no
 market activity).

 A financial instrument's level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.

 The types of instruments valued based on quoted market prices in active markets include most U.S. government and agency securities, many other sovereign government
 obligations, liquid mortgage products, active listed equities and most money market securities. Such instruments are generally classified within Level 1 or Level 2 of the fair value hierarchy. The Company does not adjust the quoted price for such
 instruments.

 The types of instruments valued based on quoted prices in markets that are not active, broker or dealer quotations or quote from alternative pricing sources with
 reasonable levels of price transparency include most investment-grade and high-yield corporate bonds, less liquid mortgage products, less liquid agency securities, less liquid listed equities, state, municipal and provincial obligations and certain
 physical commodities. Such instruments are generally classified within Level 2 of the fair value hierarchy. Certain common equity securities are reported at fair value utilizing Level 1 inputs (exchange quoted prices). Other investment securities are
 reported at fair value utilizing Level 1 and Level 2 inputs. The prices for Level 2 instruments are obtained through an independent pricing service or dealer market participants with whom the Company has historically transacted both purchases and
 sales of investment securities. Prices obtained from these sources include prices derived from market quotations and matrix pricing. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the
 U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond's terms and conditions, among other things. Management reviews the methodologies used in pricing the securities
 by its third-party providers in pricing the securities.

 Level 3 is for positions that are not traded in active markets or are subject to transfer restrictions. Valuations are adjusted to reflect illiquidity and/or
 non-transferability and such adjustments are generally based on available market evidence. In the absence of such evidence, management's best estimate will be used. Management's best estimate consists of both internal and external support on certain
 Level 3 investments. Subsequent to inception, management only changes Level 3 inputs and assumptions when corroborated by evidence such as transactions in similar instruments, completed or pending third-party transactions in the underlying investment
 or comparable entities, subsequent rounds of financing, recapitalizations and other transactions across the capital structure, offerings in the equity or debt markets and changes in financial ratios or cash flows.

 Other Financial Instruments

 The Company is a party to certain financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These
 financial instruments include commitments to extend credit, unused lines of credit, standby letter of credit and certain agricultural real estate loans sold to investors with recourse. The Company's policy is to record such instruments when funded.

 Standby letters of credit are conditional commitments issued to guarantee the performance of a customer to a third-party. The risk involved in issuing standby letters of
 credit is essentially the same as the credit risk involved in extending loan facilities to customers. Under the standby letters of credit, the Company is required to make payments to the beneficiary of the letters of credit upon request by the
 beneficiary contingent upon the customer's failure to perform under the terms of the underlying contract with the beneficiary. Standby letters of credit typically have one year expirations with an option to renew upon annual review. The Company typically receives a fee for these transactions. The fair value of standby letters of credit is recorded upon inception.

 Repurchase Agreements

 Repurchase agreements are accounted for as secured financing transactions since the Company maintains effective control over the transferred
 securities and the transfer meets the other criteria for such accounting. Obligations to repurchase securities sold are reflected as a liability in the consolidated balance sheets. The securities underlying the agreements are delivered to a custodial
 account for the benefit of the counterparties with whom each transaction is executed. The counterparties, who may sell, loan or otherwise dispose of such securities to other parties in the normal course of their operations, agree to resell to the
 Company the same securities at the maturities of the agreements.

 Table

 Revenue from Contracts with Customers

 The Company recognizes revenue in accordance with ASU 2014-09, Revenue

 from Contracts with Customers (Accounting Standards Codification ("ASC") Topic 606) ("ASC 606"), and all subsequent ASUs that modified ASC 606. ASC 606 does not apply to revenue associated with financial instruments, including revenue from
 loans and securities and certain noninterest income streams such as fees associated with mortgage servicing rights, financial guarantees, derivatives and certain credit card fees are also not in scope. ASC 606 is applicable to noninterest revenue
 streams such as retirement plan administration fees, trust and asset management income, deposit related fees and annuity and insurance commissions. Noninterest revenue streams in-scope of ASC 606 are discussed below.

 Service Charges on Deposit Accounts

 Service charges on deposit accounts consist of overdraft fees, monthly service fees, check orders and other deposit account related fees. Overdraft, monthly service,
 check orders and other deposit account related fees are transactional based, and therefore, the Company's performance obligation is satisfied, and related revenue recognized, at a point in time. Payment for service charges on deposit accounts is
 primarily received immediately or in the following month through a direct charge to customers' accounts.

 Card Services Income

 ATM fees are primarily generated when a Company cardholder uses a non-Company ATM or a non-Company cardholder uses a Company ATM. Debit card income is primarily
 comprised of interchange fees earned whenever the Company's debit cards are processed through card payment networks. The Company's performance obligations for these revenue streams are satisfied, and related revenue recognized, when the services are
 rendered or upon completion. Payment is typically received immediately or in the following month.

 Retirement Plan Administration Fees

 Retirement plan administration fees are primarily generated for services related to the recordkeeping, administration and plan design solutions of defined benefit,
 defined contribution and revenue sharing plans. Revenue is recognized in arrears for services already provided in accordance with fees established in contracts with customers or based on rates agreed to with investment trade platforms based on ending
 investment balances held. The Company's performance obligation is satisfied, and related revenue recognized based on services completed or ending investment balances, for which receivables are recorded at the time of revenue recognition.

 Wealth Management

 Wealth Management revenue primarily is comprised of trust and other financial services revenue. Trust and asset management income is primarily
 comprised of fees earned from the management and administration of trusts, pensions and other customer assets. The Company's performance obligation is generally satisfied with the resulting fees recognized monthly, based upon services completed or
 the month-end market value of the assets under management and the applicable fee rate. Payment is generally received shortly after services are rendered or a few days after month end through a direct charge to customers' accounts. The Company does
 not earn performance-based incentives. Financial services revenue primarily consists of commissions received on brokered investment product sales. For other financial services revenue, the Company's performance obligation is generally satisfied upon
 the issuance of the annuity policy. Shortly after the policy is issued, the carrier remits the commission payment to the Company, and the Company recognizes the revenue. The Company does not earn a significant amount of trailing commission fees on
 brokered investment product sales. The majority of the trailing commission fees are calculated based on a percentage of market value of a period end and revenue is recognized when an investment product's market value can be determined.

 Insurance Revenue

 Insurance and other financial services revenue primarily consists of commissions received on insurance. The Company acts as an intermediary between
 the Company's customer and the insurance carrier. The Company's performance obligation related to insurance sales for both property and casualty insurance and employee benefit plans is generally satisfied upon the later of the issuance or effective
 date of the policy. The Company earns performance based incentives, commonly known as contingent payments, which usually are based on certain criteria established by the insurance carrier such as premium volume, growth and insured loss ratios.
 Contingent payments are accrued for based upon management's expectations for the year. Commission expense associated with sales of insurance products is expensed as incurred. The Company does not earn a significant amount of trailing commission fees
 on insurance product sales. The majority of the trailing commission fees are calculated based on a percentage of market value of a period end and revenue is recognized when an investment product's market value can be determined.

 Table

 Other

 Other noninterest income consists of other recurring revenue streams such as account and loan fees, interest rate swap fees, safe deposit box rental fees and other
 miscellaneous revenue streams. These revenue streams are primarily transactional based and payment is received immediately or in the following month, and therefore, the Company's performance obligation is satisfied, and the related revenue is
 recognized, at a point in time.

 Contract Balances

 A contract asset balance occurs when an entity performs a service for a customer before the customer pays consideration or before payment is due, which would result in
 contract receivables or assets, respectively. A contract liability balance is an entity's obligation to transfer a service to a customer for which the entity has already received payment or for which payment is due from the customer. The Company's
 noninterest revenue streams are largely based on transactional activity, or standard month-end revenue accruals such as asset management fees based on month-end market values. Consideration is often received immediately or shortly after the Company
 satisfies its performance obligation and revenue is recognized. The Company does not typically enter into long-term revenue contracts with customers, and therefore, does not experience significant contract balances.

 Contract Acquisition Costs

 ASC 606 requires the capitalization, and subsequently amortization into expense, of certain incremental costs of obtaining a contract with a customer if these costs are
 expected to be recovered. The incremental costs of obtaining a contract are those costs that an entity incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained. The Company elected the
 practical expedient, which allows immediate expensing of contract acquisition costs when the asset that would have resulted from capitalizing these costs would have been amortized in one year or less, and did not capitalize any contract acquisition
 costs as of or during the year ended December 31, 2023, 2022 and 2021.

 Trust Operations

 Assets held by the Company in a fiduciary or agency capacity for its customers are not included in the accompanying consolidated balance sheets, since such assets are
 not assets of the Company.

 Subsequent Events

 The Company has evaluated subsequent events for potential recognition and/or disclosure and there were none identified.

 Recent Accounting Pronouncements

 Recently Adopted Accounting Standards

 In March
 2022, the FASB issued ASU 2022-02, Financial Instruments - CECL Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. The ASU eliminates the guidance on TDRs and requires an
 evaluation on all loan modifications to determine if they result in a new loan or a continuation of the existing loan. The ASU also requires that entities disclose current-period gross charge-offs by year of origination. The elimination of
 the TDR guidance may be adopted prospectively for loan modifications after adoption or on a modified retrospective basis, which would also apply to loans previously modified, resulting in a cumulative effect adjustment to retained earnings in
 the period of adoption for changes in the allowance for credit losses. The amendments in this ASU are effective for the Company on January 1, 2023, with early adoption permitted. The Company adopted ASU 2022-02 on January 1, 2023 using the
 modified retrospective method and recorded a net increase to retained earnings of $ 0.5 million. The transition adjustment includes
 a $ 0.6 million impact to the allowance for credit losses on loans and a $ 0.1 million impact to the deferred tax asset.

 Table

 Accounting Standards Issued Not Yet Adopted

 In October 2023, the
 FASB issued ASU 2023-06, Disclosure Improvements, which amends the disclosure or presentation requirements related to various subtopics in the FASB Accounting Standards Codification. The ASU was issued in
 response to the SEC's August 2018 final rule that updated and simplified disclosure requirements that the SEC believed were redundant, duplicative, overlapping, outdated, or superseded. The new guidance is intended to align GAAP requirements with
 those of the SEC. The ASU will become effective on the earlier of the date on which the SEC removes its disclosure requirements for the related disclosure or June 30, 2027. Early adoption is not permitted. The adoption, other than to meet the new
 disclosure requirements, is not expected to have a material impact on the consolidated financial statements.

 In December
 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures, that addresses requests for improved income tax disclosures from investors, lenders, creditors and other allocators of capital
 that use the financial statements to make capital allocation decisions. The ASU requires enhanced disclosures primarily related to existing rate reconciliation and income taxes paid information to help investors better assess how the Company's
 operations and related tax risks and tax planning and operational opportunities affect the Company's tax rate and prospects for future cash flows. The ASU 2023-09 improves the transparency of income tax. The amendments in this ASU are effective
 for the Company on January 1, 2025 and should be applied on a prospective basis. Retrospective application and early adoption are permitted. The adoption, other than to meet the new disclosure requirements, is not expected to have a material
 impact on the consolidated financial statements.

 Acquisitions

 Salisbury Bancorp, Inc.

 On August 11, 2023, the Company completed the acquisition of Salisbury Bancorp, Inc. ("Salisbury") through the merger of Salisbury with and into the
 Company, with the Company surviving the merger, for $ 161.7 million in stock. Salisbury Bank and Trust Company, Salisbury's wholly-owned
 bank subsidiary, was a Connecticut-chartered commercial bank headquartered in Lakeville, Connecticut with 13 banking offices. The
 acquisition enhances the Company's presence in Massachusetts' Berkshire county, and extends its footprint into New York's Dutchess, Orange and Ulster counties and Connecticut's Litchfield county. In connection with the acquisition, the Company issued
 4.32 million shares and acquired approximately $ 1.46 billion of identifiable assets. Goodwill of $ 79.7 million was recognized as a result of the merger
 and is not amortizable or deductible for tax purposes. During the fourth quarter of 2023, the Company revised the estimated fair value of premises and equipment, net and related deferred income taxes based upon receipt of land and building
 appraisals, which resulted in a $ 1.7 million increase in goodwill. The effects of the acquired assets and liabilities have been included in
 the consolidated financial statements since that date. As a result of the full integration of the operations of Salisbury, it is not practicable to determine all revenue or net income included in the Company's operating results relating to Salisbury
 since the date of acquisition as Salisbury results cannot be separately identified.

 The Company determined that this acquisition constitutes a business combination and therefore was accounted for using the acquisition method of
 accounting. Accordingly, as of the date of the acquisition, the Company recorded the assets acquired, liabilities assumed and consideration paid at fair value based on management's best estimates using information available at the date of the
 acquisition and these estimates are subject to adjustment based on updated information not available at the time of the acquisition. The amount of goodwill arising from the acquisition consists largely of the synergies and economies of scale expected
 from combining the operations of the Company with Salisbury. Accrued income taxes and deferred taxes associated with the Salisbury acquisition were recorded on a provisional basis and could vary from the actual recorded balance and tax provisions
 when returns are finalized.

 Table

 The following is a description of the valuation methodologies used to estimate the fair values of major categories of assets acquired and liabilities assumed. The Company used an independent valuation specialist
 to assist with the determination of fair values for certain acquired assets and assumed liabilities.

 Cash and due from banks - The estimated fair value was determined to approximate the carrying amount of these assets.

 Securities available for sale - The estimated fair value of the investment portfolio was based on quoted market prices and dealer quotes. The investment securities were sold
 immediately after the acquisition and no gains or losses were recorded.

 Loans - The estimated fair value of loans were based on a discounted cash flow methodology applied on a pooled basis for non-purchased credit deteriorated ("non-PCD") loans and for
 purchased credit deteriorated ("PCD") loans. The valuation considered underlying characteristics including loan type, term, rate, payment schedule and credit rating. Other factors included assumptions related to prepayments, probability of
 default and loss given default. The discount rates applied were based on a build-up approach considering the funding mix, servicing costs, liquidity premium and factors related to performance risk.

 Core deposit intangible - The core deposit intangible was valued utilizing the cost savings method approach, which recognizes the cost savings represented by the expense of
 maintaining the core deposit base versus the cost of an alternative funding source. The valuation incorporates assumptions related to account retention, discount rates, deposit interest rates, deposit maintenance costs and alternative funding
 rates.

 Wealth management customer intangible - The wealth management customer intangible was valued utilizing the income approach, which employs a present value analysis, which
 calculates the expected after-tax cash flow benefits of the net revenues generated by the acquired customers over the expected lives of the acquired customers, discounted at a long-term market-oriented after-tax rate of return on investment. The
 value assigned to the acquired customers represents the future economic benefit from acquiring the customers (net of operating expenses).

 Deposits - The fair value of noninterest bearing demand deposits, interest checking, money market and savings deposit accounts from Salisbury were assumed to approximate the
 carrying value as these accounts have no stated maturity and are payable on demand. Certificate of deposit (time deposit accounts) were valued at the present value of the certificates' expected contractual payments discounted at market rates for
 similar certificates.

 Borrowings - The estimated fair value of short-term borrowings was determined to approximate stated value. Subordinated debt was valued using a discounted cash flow approach
 incorporating a discount rate that incorporated similar terms, maturity and credit rating.

 Accounting for Acquired Loans - Acquired loans are classified into two categories: PCD loans and non-PCD loans. PCD loans are defined
 as a loan or group of loans that have experienced more than insignificant credit deterioration since origination. Non-PCD loans will have an allowance established on the acquisition date, which is recognized as an expense through the provision
 for credit losses. For PCD loans, an allowance is recognized on day 1 by adding it to the fair value of the loan, which is the "Day 1 amortized cost". There is no provision for credit loss expense recognized on PCD loans because the initial
 allowance is established by grossing-up the amortized cost of the PCD loan. A day 1 allowance for credit losses on non-PCD loans of $ 8.8
 million was recorded through the provision for loan losses within the unaudited interim consolidated statements of income. The

 following table provides details related to the fair value of acquired PCD loans.

 allowance for credit losses on HTM securities as of December 31, 2023 and 2022 because the expectation of nonrepayment of the amortized cost is zero, except for state & municipal securities, which such expected
 losses from nonrepayment were immaterial.

 The Company recorded no gains from calls on HTM securities for year ended December 31,
 2023. Included in net securities (losses) gains, the Company recorded gains from calls on HTM securities of approximately $ 4 thousand for
 the year ended December 31, 2022 and approximately $ 29 thousand for the year ended December 31, 2021.

 AFS and HTM securities with amortized costs totaling $ 2.03 billion at December 31, 2023 and $ 1.73
 billion at December 31, 2022 were pledged to secure public deposits and for other purposes required or permitted by law. Additionally, at December 31, 2023 and 2022, AFS and HTM securities with an amortized cost of $ 177.2 million and $ 149.5 million,
 respectively, were pledged as collateral for securities sold under repurchase agreements.

 Table

 The Company does not believe the AFS securities that were in an unrealized loss position as of December 31, 2023 and 2022, which consisted of 388 and 415 individual securities,
 respectively, represented a credit loss impairment. AFS debt securities in unrealized loss positions are evaluated for impairment related to credit losses at least quarterly. As of December 31, 2023 and 2022, the majority of the AFS securities in an
 unrealized loss position consisted of debt securities issued by U.S. government agencies or U.S. government-sponsored enterprises that carry the explicit and/or implicit guarantee of the U.S. government, which are widely recognized as "risk-free" and
 have a long history of zero credit losses. Total gross unrealized losses were primarily attributable to changes in interest rates, relative to when the investment securities were purchased, and not due to the credit quality of the investment
 securities. The Company does not intend to sell, nor is it more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis, which may be at maturity. The Company elected to exclude accrued
 interest receivable ("AIR") from the amortized cost basis of debt securities. AIR on AFS debt securities totaled $ 3.9 million at December
 31, 2023 and $ 4.2 million at December 31, 2022 and is excluded from the estimate of credit losses and reported in the other assets financial statement line.

 None of the Bank's HTM debt securities were past due
 or on nonaccrual status as of December 31, 2023 and 2022. There was no accrued interest reversed against interest income for the years
 ended December 31, 2023 and 2022 as all securities remained on accrual status. In addition, there were no collateral-dependent HTM
 debt securities as of December 31, 2023 and 2022. As of December 31, 2023 and 2022, 66 % and 70 %, respectively, of the Company's HTM debt securities were issued by U.S. government agencies or U.S. government-sponsored enterprises. These securities carry the explicit
 and/or implicit guarantee of the U.S. government, which are widely recognized as "risk free," and have a long history of zero credit loss. Therefore, the Company did not record an allowance for credit losses for these securities as of December 31,
 2023 and 2022. The remaining HTM debt securities at December 31, 2023 and 2022 were comprised of state and municipal obligations generally with bond ratings of A to AAA. Utilizing the CECL methodology, the Company determined that the expected credit
 loss on its HTM municipal bond portfolio was immaterial and therefore no allowance for credit loss was recorded as of December 31, 2023 and 2022. AIR on HTM debt securities totaled $ 4.7 million at December 31, 2023 and $ 3.8 million at December 31, 2022 and is
 excluded from the estimate of credit losses and reported in the other assets financial statement line.

 Included in the above loans are net deferred loan origination (fees) costs totaling $( 98.2) million and $( 109.1) million at December 31, 2023 and 2022, respectively. The
 Company had $ 0.4 million and $ 0.6
 million of residential real estate loans held for sale as of December 31, 2023 and 2022, respectively. Beginning in 2023, the Company began selling residential solar loans. As of December 31, 2023 the Company had $ 2.9 million of residential solar loans held for sale.

 The total amount of loans serviced by the Company for unrelated third parties was $ 856.9 million and $ 592.7 million at December 31, 2023 and 2022, respectively. At
 December 31, 2023 and 2022,
 the Company had $ 1.0 million and $ 0.6
 million, respectively, of mortgage servicing rights.

 At December 31, 2023 and 2022, the Company serviced $ 26.4 million
 and $ 31.0 million, respectively, of agricultural loans sold with recourse. Due to sufficient collateral on these loans and government
 guarantees, no reserve is considered necessary at December 31, 2023 and 2022.

 FHLB advances are collateralized by a blanket lien on the Company's residential real estate mortgages.

 In the ordinary course of business, the Company has made loans at prevailing rates and terms to directors, officers and other related parties. Such loans, in
 management's opinion, do not present more than the normal risk of collectability or incorporate other unfavorable features. The aggregate amount of loans outstanding to qualifying related parties and changes during the years are summarized as

 6. Allowance for Credit Losses and Credit Quality of Loans

 As described in Note 2, the Company's adoption of ASU 2022-02 resulted in an insignificant change to its methodology for estimating the allowance for credit losses on TDRs. The decrease in allowance for credit loss on TDR loans relating to
 the adoption of ASU 2022-02 was $ 0.6 million.

 The allowance for credit losses totaled $ 114.4 million at December 31, 2023, compared to $ 100.8 million at December
 31, 2022. The allowance for credit losses as a percentage of loans was 1.19 % at December 31, 2023, compared
 to 1.24 % at December 31, 2022.

 The allowance for credit losses calculation incorporated a 6-quarter forecast period to account for forecast economic conditions under each scenario
 utilized in the measurement. For periods beyond the 6-quarter forecast, the model reverts to long-term economic conditions over a 4-quarter reversion period on a straight-line basis. The Company considers a baseline, upside and downside economic
 forecast in measuring the allowance.

 The quantitative model as of December 31, 2023 incorporated a baseline economic outlook along with an alternative downside scenario sourced from a
 reputable third-party to accommodate other potential economic conditions in the model. At December 31, 2023, the weightings were 70% and 30% for the baseline and downside economic forecasts, respectively. The baseline outlook reflected an
 unemployment rate environment starting at 3.8% and increasing slightly during the forecast period to 4.1%. Northeast GDP's annualized growth (on a quarterly basis) was expected to start the first quarter of 2024 at approximately 3.7% before
 decreasing to a low of 2.9% in the third quarter of 2024 and then increasing to 3.8% by the end of the forecast period. Other utilized economic variable forecasts are mixed compared to the prior year, with retail sales improving, business output
 mixed and housing starts down. Key assumptions in the baseline economic outlook included currently being in a full employment economy, continued tapering of the Federal Reserve balance sheet and the Federal Open Market Committee ("FOMC") beginning
 to cut rates in the second quarter of 2024. The alternative downside scenario assumed deteriorated economic conditions from the baseline outlook. Under this scenario, northeast unemployment increases to a peak of 7.0% in the first quarter of 2025.
 These scenarios and their respective weightings are evaluated at each measurement date and reflect management's expectations as of December 31, 2023. Additional qualitative adjustments were made for factors not incorporated in the forecasts or the
 model, such as loss rate expectations for certain loan pools, considerations for inflation and recent trends in asset value indices. Additional monitoring for industry concentrations, loan growth and policy exceptions was also conducted.

 The quantitative model as of December 31, 2022 incorporated a baseline economic outlook along with an alternative downside scenario sourced from a
 reputable third-party to accommodate other potential economic conditions in the model. At December 31, 2022, the weightings were 50% and 50% for the baseline and downside economic forecasts, respectively. The baseline outlook reflected an
 unemployment rate environment initially around pre-coronavirus ("COVID-19") levels at 3.9% that increases slightly during the forecast period to 4.0%. Northeast GDP's annualized growth (on a quarterly basis) was expected to start the first quarter
 of 2023 at approximately 3.9% and hovering around 4.6% by the end of the forecast period. Other utilized economic variables have generally deteriorated in their respective forecasts, with retail sales and housing starts forecasts declining from the
 prior year. Key assumptions in the baseline economic outlook included a full employment economy being realized in the near future, continued tapering of the Federal Reserve balance sheet, an increasing yield on ten-year treasury securities and a
 gradual decline in global oil prices. The alternative downside scenario assumed deteriorated economic and pandemic related conditions from the baseline outlook. Under this scenario, northeast unemployment rises from 3.9% in the fourth quarter of
 2022 to a peak of 6.9% in the first quarter of 2024. These scenarios and their respective weightings are evaluated at each measurement date and reflect management's expectations as of December 31, 2022. Additional qualitative adjustments were made
 for factors not incorporated in the forecasts or the model, such as loss rate expectations for certain loan pools, considerations for inflation and recent trends in asset value indices. Additional monitoring for industry concentrations, loan growth
 and policy exceptions was also conducted.

 The quantitative model as of December 31, 2021 incorporated a baseline economic outlook along with alternative upside and downside scenarios sourced
 from a reputable third-party to accommodate other potential economic conditions in the model. The baseline outlook reflected an unemployment rate environment initially above pre-COVID-19 levels at 4.8% but falling below pre-COVID-19 levels by the
 end of the forecast period to 3.5%. Northeast GDP's annualized growth (on a quarterly basis) was expected to start the first quarter of 2022 at approximately 9% and hover around 5% by the middle and end of the forecast period. The alternative
 downside scenario assumed deteriorated economic and pandemic related conditions from the baseline outlook. Under this scenario, northeast unemployment rose from 5.7% in the fourth quarter of 2021 to a peak of 8% in the first quarter of 2023,
 remaining around or above 7% for the entire forecast period. The alternative upside scenario incorporated a more optimistic outlook than the baseline scenario, with a swift return to full employment by the second quarter of 2022 and with northeast
 unemployment moving down to 3.1% by the end of the forecast period. These scenarios and their respective weightings are evaluated at each measurement date and reflect management's expectations as of December 31, 2021. At December 31, 2021, the
 weightings were 60%, 10% and 30% for the baseline, upside and downside economic forecasts, respectively. Additional adjustments were made for COVID-19 related factors not incorporated in the forecasts, such as the mitigating impact of unprecedented
 stimulus in the second and third quarters of 2020, including direct payments to individuals, increased unemployment benefits, the Company's loan deferral and modification initiatives and various government sponsored loan programs. The Company also
 continued to monitor the level of criticized and classified loans in the fourth quarter of 2021 compared to the level contemplated by the model during similar, historical economic conditions, and an adjustment was made to estimate potential
 additional losses above modeled losses. Additionally, qualitative adjustments were made for Moody's baseline economic forecast to include impacts of the Build Back Better Act not passing by December 31, 2021 and to address potential economic
 deterioration due to Omicron, as well as isolated model limitations related to modeled outputs given abnormally high retail sales and business output growth rates in historical periods.

 There were $ 219.5 million of PCD loans acquired from Salisbury during the year ended December 31, 2023, which resulted in an allowance for credit losses at acquisition of $ 5.8 million. There were no loans purchased with credit
 deterioration during the year ended December 31, 2022. During 2023, the Company purchased $ 3.8 million of residential loans at a 7.00 %
 premium with a $ 31 thousand allowance for credit losses recorded for these loans. During 2022, the Company purchased $ 11.5 million of residential loans at a 1.53 %
 premium and $ 50.1 million of consumer loans at a par with an allowance for credit losses recorded on the purchase date of $ 3.2 million.

 The Company made a policy election to report AIR in the other assets line item on the consolidated balance sheets. AIR on loans totaled $ 34.1 million at December 31, 2023 and $ 25.0 million at December 31, 2022 and there was no estimated allowance for credit losses related to AIR at December 31, 2023 and 2022 as it is excluded from amortized cost.

 The allowance for credit losses as of December 31, 2023 increased compared to the allowance estimates as of December 31, 2022 due to the recording of $ 14.5 million of allowance for acquired Salisbury loans as of the acquisition date, which included both the $ 8.8 million of non-PCD allowance recognized through the provision for loan losses and the $ 5.8 million of PCD allowance reclassified from loans. The increase in the allowance for credit losses from December 31, 2021 to December 31, 2022 was primarily due to an increase in loan balances and a modest
 deterioration in the economic forecast. The decrease in the allowance for credit losses from December 31, 2020 to December 31, 2021 was primarily due to the improvement in the economic forecast, partly offset by providing for the increase in loan
 balances.

 Individually Evaluated Loans

 As of December 31, 2023, there were two relationships identified to be evaluated for loss on an individual basis which had an amortized cost basis of $ 17.3 million, with no allowance for credit loss. As of December 31, 2022, two
 different relationships were identified to be evaluated for loss on an individual basis, which in aggregate, had an amortized cost basis of $ 2.4 million, with no
 allowance for credit loss.

 As of December 31, 2023 and 2022, there were $ 17.3 million and $ 1.1 million, respectively, of loans in
 nonaccrual that were specifically evaluated for individual expected credit loss without an allowance for credit losses.

 Credit Quality Indicators

 The Company has developed an internal loan grading system to evaluate and quantify the Company's loan portfolio with respect to quality and risk. The system focuses
 on, among other things, financial strength of borrowers, experience and depth of borrower's management, primary and secondary sources of repayment, payment history, nature of the business and outlook on particular industries. The internal grading
 system enables the Company to monitor the quality of the entire loan portfolio on a consistent basis and provide management with an early warning system, which facilitates recognition and response to problem loans and potential problem loans.

 Commercial Grading System

 For Commercial and Industrial ("C&I") and Commercial Real Estate ("CRE") loans, the Company uses a grading system that relies on quantifiable and measurable
 characteristics when available. This includes comparison of financial strength to available industry averages, comparison of transaction factors (loan terms and conditions) to loan policy and comparison of credit history to stated repayment terms
 and industry averages. Some grading factors are necessarily more subjective such as economic and industry factors, regulatory environment and management. C&I and CRE loans are graded Doubtful, Substandard, Special Mention and Pass.

 Doubtful

 A Doubtful loan has a high probability of total or substantial loss, but because of specific pending events that may strengthen the asset, its
 classification as a loss is deferred. Doubtful borrowers are usually in default, lack adequate liquidity or capital and lack the resources necessary to remain an operating entity. Pending events can include mergers, acquisitions, liquidations,
 capital injections, the perfection of liens on additional collateral, the valuation of collateral and refinancing. Generally, pending events should be resolved within a relatively short period and the ratings will be adjusted based on the new
 information. Nonaccrual treatment is required for Doubtful assets because of the high probability of loss.

 Substandard loans have a high probability of payment default or they have other well-defined weaknesses. They require more intensive supervision
 by bank management. Substandard loans are generally characterized by current or expected unprofitable operations, inadequate debt service coverage, inadequate liquidity or marginal capitalization. Repayment may depend on collateral or other
 credit risk mitigants. For some Substandard loans, the likelihood of full collection of interest and principal may be in doubt and those loans should be placed on nonaccrual. Although Substandard assets in the aggregate will have a distinct
 potential for loss, an individual asset's loss potential does not have to be distinct for the asset to be rated Substandard.

 Table

 Special Mention

 Special Mention loans have potential weaknesses that may, if not checked or corrected, weaken the asset or inadequately protect the Company's
 position at some future date. These loans pose elevated risk, but their weakness does not yet justify a Substandard classification. Borrowers may be experiencing adverse operating trends (i.e., declining revenues or margins) or may be struggling
 with an ill-proportioned balance sheet (i.e., increasing inventory without an increase in sales, high leverage and/or tight liquidity). Adverse economic or market conditions, such as interest rate increases or the entry of a new competitor, may
 also support a Special Mention rating. Although a Special Mention loan has a higher probability of default than a Pass asset, its default is not imminent.

 Pass

 Loans graded as Pass encompass all loans not graded as Doubtful, Substandard or Special Mention. Pass loans are in compliance with loan covenants
 and payments are generally made as agreed. Pass loans range from superior quality to fair quality. Pass loans also include any portion of a government guaranteed loan, including Paycheck Protection Program loans.

 Consumer and Residential Grading System

 Consumer and Residential loans are graded as either Nonperforming or Performing.

 Nonperforming loans are loans that are (1) over 90 days past due and interest is still accruing or (2) on nonaccrual status.

 All loans not meeting any of the above criteria are considered Performing.

 Table

 The following tables illustrate the Company's credit
 quality by loan class by vintage and, beginning in 2023 with the Company's January 1, 2023 adoption of ASU 2022-02, also includes gross charge-offs by loan class by vintage for the year ended December 31, 2023. Included in other consumer gross
 charge-offs, the Company recorded $ 0.2 million in overdrawn deposit accounts reported as 2022 originations and $ 0.8 million in overdrawn deposit accounts reported as 2023 originations for the year ended December 31, 2023.

 Allowance for Credit Losses on
 Off-Balance Sheet Credit Exposures

 The allowance for losses on unfunded commitments totaled $ 5.1
 million as of December 31, 2023 and December 31, 2022, which included $ 0.8 million of acquisition-related provision for unfunded loan commitments as of December 31, 2023, which was offset by a release of unfunded commitment reserves.

 Loan Modifications to Borrowers Experiencing Financial Difficulties

 As discussed in Note 2, the Company's January 1, 2023 adoption of ASU 2022-02 eliminates the recognition and measurement of TDRs. Upon adoption of this guidance, the Company no longer recognizes an allowance for credit losses for the
 economic concession granted to a borrower for changes in the timing and amount of contractual cash flows when a loan is restructured. The adoption of ASU 2022-02 resulted in a change to reporting for loan modifications to borrowers experiencing
 financial difficulties. With the adoption of ASU 2022-02 these modifications required enhanced reporting on the type of modifications granted and the financial magnitude of the concessions granted.

 When the Company modifies a loan with financial difficulty, such modifications generally include one or a combination of the following: an extension of the maturity date at a stated rate of interest lower than the current market rate for
 new debt with similar risk; a change in scheduled payment amount; or principal forgiveness.

 The following table shows the amortized cost basis at the end of the reporting period of the loans modified to borrowers experiencing financial difficulty,
 disaggregated by class of financing receivable and type of concession granted:

 Troubled Debt Restructuring

 Prior to the adoption of ASU 2022-02 on January 1, 2023, the Company accounted for loan modifications to borrowers experiencing financial difficulty when concessions
 were granted as TDRs. The following tables are disclosures related to TDRs in prior periods.

 The following tables illustrate the recorded investment and number of modifications designated as TDRs, including the recorded

 Operating leases in which the Company is the lessee are recorded as operating lease ROU assets and operating lease liabilities, included in other assets and other liabilities,
 respectively, on the consolidated balance sheets. The Company does not have any significant finance leases in which we are the lessee as of December 31, 2023 and December 31, 2022.

 Operating lease ROU assets represent the Company's right to use an underlying asset during the lease term and operating lease liabilities represent
 our obligation to make lease payments arising from the lease. ROU assets and operating lease liabilities are recognized at lease commencement based on the present value of the remaining lease payments using a discount rate that represents the
 Company's incremental borrowing rate at the lease commencement date. ROU assets are further adjusted for lease incentives. Operating lease expense, which is comprised of amortization of the ROU asset and the implicit interest accreted on the
 operating lease liability, is recognized on a straight-line basis over the lease term and is recorded in occupancy expense in the consolidated statements of income.

 The Company made a policy election to exclude the recognition requirements to all classes of leases with original terms of 12 months or less.
 Instead, the short-term lease payments are recognized in profit or loss on a straight-line basis over the lease term.

 Table

 The Company has lease agreements with lease and non-lease components, which are generally accounted for separately. For real estate leases,
 non-lease components and other non-components, such as common area maintenance charges, real estate taxes and insurance are not included in the measurement of the lease liability since they are generally able to be segregated.

 Our leases relate primarily to office space and bank branches, and some contain options to renew the lease. These options to renew are generally not
 considered reasonably certain to exercise, and are therefore not included in the lease term until such time that the option to renew is reasonably certain. As of December 31, 2023, operating lease ROU assets and liabilities were $ 26.7 million and $ 28.2 million,
 respectively. As of December 31, 2022, operating lease ROU assets and liabilities were $ 23.9 million and $ 25.6 million, respectively.

 10. Borrowings

 Short-Term Borrowings

 In addition to the liquidity provided by balance sheet cash flows, liquidity must also be supplemented with additional sources such as credit lines from correspondent
 banks as well as borrowings from the FHLB and the Federal Reserve Bank. Other funding alternatives may also be appropriate from time to time, including wholesale and retail repurchase agreements and brokered certificate of deposit ("CD") accounts.

 Table

 Short-term borrowings totaled $ 386.7 million and $ 585.0 million at December 31, 2023 and
 2022, respectively, and consist of Federal funds purchased and securities sold under repurchase agreements, which generally represent
 overnight borrowing transactions and other short-term borrowings, primarily FHLB advances, with original maturities of one year or less.

 The Company has unused lines of credit with the FHLB and access to brokered deposits available for short-term financing. Those sources totaled approximately $ 2.87 billion and $ 2.90 billion at
 December 31, 2023 and 2022,
 respectively. Borrowings on the FHLB lines are secured by FHLB stock, certain securities and one-to-four family first lien mortgage loans. Securities collateralizing repurchase agreements are held in safekeeping by nonaffiliated financial
 institutions and are under the Company's control.

 Information related to short-term borrowings is summarized as follows:

 Long-Term Debt

 Long-term debt consists of obligations having an original maturity at issuance of more than one year. A majority of the Company's long-term debt
 is comprised of FHLB advances collateralized by the FHLB stock owned by the Company, and a blanket lien on its residential real estate mortgage loans. As of December 31, 2023 the Company had no callable long-term debt. A summary is as follows:

 Subordinated Debt

 On June 23, 2020, the Company issued $ 100.0
 million aggregate principal amount of 5.00 % fixed-to-floating rate subordinated notes due 2030. The subordinated notes, which qualify
 as Tier 2 capital, bear interest at an annual rate of 5.00 %, payable semi-annually in arrears commencing on January 1, 2021, and a
 floating rate of interest equivalent to the three-month Secured Overnight Financing Rate ("SOFR") plus a spread of 4.85 %, payable quarterly in arrears commencing on October 1, 2025. The subordinated notes issuance costs of $ 2.2 million are being amortized on a straight-line basis into interest expense over five years.

 The Company may redeem the subordinated notes (1) in whole or in part beginning with the interest payment date of July 1, 2025, and on any
 interest payment date thereafter or (2) in whole but not in part upon the occurrence of a "Tax Event", a "Tier 2 Capital Event" or in the event the Company is required to register as an investment company pursuant to the Investment Company Act of
 1940, as amended. The redemption price for any redemption is 100 % of the principal amount of the subordinated notes being redeemed,
 plus accrued and unpaid interest thereon to, but excluding, the date of redemption. Any redemption of the subordinated notes will be subject to the receipt of the approval of the Board of Governors of the Federal Reserve System to the extent then
 required under applicable laws or regulations, including capital regulations. The Company repurchased $ 2.0 million of the subordinated notes during the year ended December 31, 2022 at a discount of $ 0.1 million.

 Table

 The subordinated notes assumed in connection with the Salisbury acquisition
 included $ 25.0 million of 3.50 %
 fixed-to-floating rate subordinated notes due 2031. The subordinated notes, which qualify as Tier 2 capital, have a maturity date of March 31, 2031 and bear interest at an annual rate of 3.50 %, payable quarterly in arrears commencing on June 30, 2021, and a floating rate of interest equivalent to the three-month SOFR plus a spread of 2.80 %, payable quarterly
 in arrears commencing on June 30, 2026. The subordinated notes are redeemable, without penalty, on or after March 31, 2026 and, in certain limited circumstances, prior to that date. As of the acquisition date, the fair value discount was $ 3.0 million.

 The following table summarizes the Company's subordinated debt:

 2022

 Junior Subordinated Debt

 The Company sponsors five
 business trusts, CNBF Capital Trust I, NBT Statutory Trust I, NBT Statutory Trust II, Alliance Financial Capital Trust I and Alliance Financial Capital Trust II (collectively, the "Trusts"). The Company's junior subordinated debentures include
 amounts related to the Company's NBT Statutory Trust I and II as well as junior subordinated debentures associated with one statutory
 trust affiliate that was acquired from our merger with CNB Financial Corp. and two statutory trusts that were acquired from our
 acquisition of Alliance Financial Corporation ("Alliance"). The Trusts were formed for the purpose of issuing company-obligated mandatorily redeemable trust preferred securities to third-party investors and investing in the proceeds from the sale
 of such preferred securities solely in junior subordinated debt securities of the Company for general corporate purposes. The Company guarantees, on a limited basis, payments of distributions on the trust preferred securities and payments on
 redemption of the trust preferred securities. The Trusts are VIEs for which the Company is not the primary beneficiary, as defined by GAAP. In accordance with GAAP, the accounts of the Trusts are not included in the Company's consolidated
 financial statements. See Note 1 for additional information about the Company's consolidation policy.

 The debentures held by each trust are the sole assets of that trust. The Trusts hold, as their sole assets, junior subordinated debentures of
 the Company with face amounts totaling $ 98.0 million at December 31, 2023. The Company owns all of the common securities of the Trusts
 and has accordingly recorded $ 3.2 million in equity method investments classified as other assets in our consolidated balance sheets at
 December 31, 2023. The Company owns all of the common stock of the Trusts, which have issued trust preferred securities in conjunction with the Company issuing trust preferred debentures to the Trusts. The terms of the trust preferred debentures
 are substantially the same as the terms of the trust preferred securities.

 As of December 31, 2023, the Trusts had the following trust preferred securities outstanding and held the following junior subordinated
 debentures of the Company (dollars in thousands):

 Table

 The Company's junior subordinated debentures are redeemable prior to the maturity date at our option upon each trust's stated option repurchase
 dates and from time to time thereafter. These debentures are also redeemable in whole at any time upon the occurrence of specific events defined within the trust indenture. Our obligations under the debentures and related documents, taken
 together, constitute a full and unconditional guarantee by the Company of the issuers' obligations under the trust preferred securities. The Company owns all of the common stock of the Trusts, which have issued trust preferred securities in
 conjunction with the Company issuing trust preferred debentures to the Trusts. The terms of the trust preferred debentures are substantially the same as the terms of the trust preferred securities.

 With respect to the Trusts, the Company has the right to defer payments of interest on the debentures issued to the Trusts at any time or from
 time to time for a period of up to ten consecutive semi-annual periods with respect to each deferral period. Under the terms of the
 debentures, if in certain circumstances there is an event of default under the debentures or the Company elects to defer interest on the debentures, the Company may not, with certain exceptions, declare or pay any dividends or distributions on
 its capital stock or purchase or acquire any of its capital stock.

 Despite the fact that the Trusts are not included in the Company's consolidated financial statements, $ 97 million of the $ 101 million in trust preferred securities
 issued by these subsidiary trusts is included in the Tier 1 capital of the Company for regulatory capital purposes as allowed by the Federal Reserve Board (NBT Bank owns $ 1.0 million of CNBF Trust I securities). The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 requires bank holding companies with assets greater than $ 500 million to be subject to the same capital requirements as insured depository institutions, meaning, for instance, that such bank holding companies
 will not be able to count trust preferred securities issued after May 19, 2010 as Tier 1 capital. The aforementioned Trusts are grandfathered with respect to this enactment based on their date of issuance.

 Realization of deferred tax assets is dependent upon the generation of future taxable income. A valuation allowance is recorded when it is more likely than not that
 some portion of the deferred tax asset will not be realized. Based on available evidence, gross deferred tax assets will ultimately be realized and a valuation allowance was not deemed necessary at December 31, 2023 and 2022.

 The Company recognizes interest and penalties on the income tax expense line in the accompanying consolidated statements of income. The Company monitors changes in
 tax statutes and regulations to determine if significant changes will occur over the next 12 months. As of December 31, 2023, no
 significant changes to UTBs are projected; however, tax audit examinations are possible, but it is not reasonably possible to estimate when examinations in
 subsequent years will be completed. The Company recognized an insignificant amount of interest expense related to UTBs in the consolidated statement of income for the year ended December 31, 2023, 2022 and 2021.

 As of December 31, 2023, the Company is no longer subject to U.S. Federal tax examination by tax authorities for years prior to 2020. The tax years 2017 to 2019 are currently being audited by New York State.

 12. Employee Benefit Plans

 Defined Benefit Post-Retirement Plans

 The Company has a qualified, noncontributory, defined benefit pension plan ("the Plan") covering substantially all of its employees at December 31, 2023. Benefits paid
 from the Plan are based on age, years of service, compensation and social security benefits and are determined in accordance with defined formulas. The Company's policy is to fund the Plan in accordance with Employee Retirement Income Security Act of
 1974 standards. Assets of the Plan are invested in publicly traded stocks, bonds and mutual funds. Prior to January 1, 2000, the Plan was a traditional defined benefit plan based on final average compensation. On January 1, 2000, the Plan was
 converted to a cash balance plan with grandfathering provisions for existing participants. Effective March 1, 2013, the Plan was amended. Benefit accruals for participants who, as of January 1, 2000, elected to continue participating in the
 traditional defined benefit plan design were frozen as of March 1, 2013. In May 2013, the noncontributory, frozen, defined benefit pension plan assumed from Alliance in the acquisition was merged into the Plan. In addition to the Plan, the Company
 provides supplemental employee retirement plans to certain current and former executives. The Company also assumed supplemental retirement plans for former executives in the Alliance acquisition. These supplemental employee retirement plans and the
 Plan are collectively referred to herein as "Pension Benefits."

 Table

 In addition, the Company provides certain health care benefits for retired employees. Benefits were accrued over the employees' active service period. Only employees
 that were employed by the Company on or before January 1, 2000 are eligible to receive post-retirement health care benefits. The Plan is contributory for participating retirees, requiring participants to absorb certain deductibles and coinsurance
 amounts with contributions adjusted annually to reflect cost sharing provisions and benefit limitations called for in the Plan. Employees become eligible for these benefits if they reach normal retirement age while working for the Company. For
 eligible employees described above, the Company funds the cost of post-retirement health care as benefits are paid. The Company elected to recognize the transition obligation on a delayed basis over twenty years. In addition, the Company assumed post-retirement medical life insurance benefits for certain Alliance employees, retirees and their spouses, if applicable, in the
 Alliance acquisition. These post-retirement benefits are referred to herein as "Other Benefits."

 Accounting standards require an employer to: (1) recognize the overfunded or underfunded status of defined benefit post-retirement plans, which is
 measured as the difference between plan assets at fair value and the benefit obligation, as an asset or liability in its balance sheet; (2) recognize changes in that funded status in the year in which the changes occur through comprehensive income;
 and (3) measure the defined benefit plan assets and obligations as of the date of its year-end balance sheet.

 The components of AOCI, which have not yet been recognized as components of net periodic benefit cost, related to pensions and other post-retirement benefits are

 The Company made no voluntary contributions to the
 pension and other benefit plans during the years ended December 31, 2023 and 2022.

 For measurement purposes, the annual rates of increase in the per capita cost of covered medical and prescription drug benefits for fiscal year 2023 were assumed to be 4.5 % to 6.5 %. The rates were assumed to
 decrease gradually to 4.0 % for fiscal year 2075 and remain at that level thereafter. Assumed health care cost trend rates have a
 significant effect on amounts reported for health care plans.

 Plan Investment Policy

 The Company's key investment objectives in managing its defined benefit plan assets are to ensure that present and future benefit obligations to all participants and
 beneficiaries are met as they become due; to provide a total return that, over the long-term, maximizes the ratio of the plan assets to liabilities, while minimizing the present value of required Company contributions, at the appropriate levels of
 risk; to meet statutory requirements and regulatory agencies' requirements; and to satisfy applicable accounting standards. The Company periodically evaluates the asset allocations, funded status, rate of return assumption and contribution strategy
 for satisfaction of our investment objectives.

 The target and actual allocations expressed as a percentage of the defined benefit pension plan's assets are as follows:

 Determination of Assumed Rate of Return

 The expected long-term rate-of-return on assets was 6.7 %
 at December 31, 2023 and 2022, respectively. This assumption represents the rate of return on plan assets reflecting the average rate of earnings expected on the funds invested or to be invested to provide for the benefits included in the projected
 benefit obligation. The assumption has been determined by reflecting expectations regarding future rates of return for the portfolio considering the asset distribution and related historical rates of return. The appropriateness of the assumption is
 reviewed annually.

 Employee 401(k) and Employee Stock Ownership Plans

 The Company maintains a 401(k) and employee stock ownership plan (the "401(k) Plan"). The Company contributes to the 401(k) Plan based on employees' contributions out of
 their annual salaries. In addition, the Company may also make discretionary contributions to the 401(k) Plan based on profitability. Participation in the 401(k) Plan is contingent upon certain age and service requirements. The employer contributions
 associated with the 401(k) Plan were $ 4.4 million in 2023, $ 4.0 million in 2022 and $ 3.9 million in 2021.

 Other Retirement Benefits

 Included in other liabilities is $ 0.9 million and $ 1.1 million at December 31, 2023 and 2022, respectively, for supplemental retirement benefits for retired executives from legacy plans assumed in
 acquisitions. The Company recognized $ 0.2 million in expense for each of the years ended December 31, 2023, 2022 and 2021, related to
 these plans.

 13. Stock-Based Compensation

 In May 2018, the Company adopted the NBT Bancorp Inc. 2018 Omnibus Incentive Plan (the "Stock Plan") replacing the 2008 Omnibus Incentive Plan which automatically
 expired in April 2018. Under the terms of the Stock Plan, equity-based awards are granted to directors and employees to increase their direct proprietary interest in the operations and success of the Company. The Stock Plan assumed all prior
 equity-based incentive plans and any new equity-based awards are granted under the terms of the Stock Plan. Restricted shares granted under the Plan typically vest
 after three or five years for employees and one or three years for non-employee directors. Restricted stock units granted under the Stock Plan may have different terms and conditions. Performance shares
 and units granted under the Stock Plan for executives may have different terms and conditions. Since 2011, the Company primarily grants restricted stock unit awards. Stock option grants since that time were reloads of existing grants which terminate
 ten years from the date of the grant. Under terms of the Stock Plan, stock options are granted to purchase shares of the Company's common
 stock at a price equal to the fair market value of the common stock on the date of the grant. Shares issued as a result of vesting of restricted stock unit awards and stock option exercises are funded from the Company's treasury stoc k.

 The Company has outstanding restricted stock granted from various plans at December 31, 2023. The Company recognized $ 5.1 million, $ 4.5 million and $ 4.4 million in stock-based compensation expense
 related to these stock awards for the years ended December 31, 2023, 2022 and 2021, respectively. Tax benefits recognized with
 respect to restricted stock units were $ 1.3 million, $ 1.2 million and $ 1.9 million for the years ended December 31, 2023, 2022 and 2021, respectively. Unrecognized compensation cost related to restricted stock units totaled $ 5.4 million at December 31, 2023 and will be recognized over 1.4 years on a weighted average basis. Shares issued are funded from the Company's treasury stock. The following table summarizes information for

 Certain restrictions exist regarding the ability of the subsidiary bank to transfer funds to the Company in the form of cash dividends. The approval of the Office of the
 Comptroller of the Currency ("OCC") is required to pay dividends when a bank fails to meet certain minimum regulatory capital standards or when such dividends are in excess of a subsidiary bank's earnings retained in the current year plus retained
 net profits for the preceding two years as specified in applicable OCC regulations. At December 31, 2023, approximately $ 106.6 million of the
 total stockholders' equity of the Bank was available for payment of dividends to the Company without approval by the OCC. The Bank's ability to pay dividends also is subject to the Bank's being in compliance with regulatory capital requirements. The
 Bank is currently in compliance with these requirements. Under the State of Delaware General Corporation Law, the Company may declare and pay dividends either out of accumulated net retained earnings or capital surplus.

 The Company purchased 155,500 shares of its common stock
 during the year ended December 31, 2023, for a
 total of $4.9 million at an average price of $31.79 per share under its previously announced share repurchase
 program. This repurchase program under which these shares were purchased was due to expire on December 31, 2023; however, on December 18, 2023, the Board of Directors authorized and approved an amendment to the repurchase program. Pursuant to the amended stock repurchase program, the
 Company may repurchase up to 2,000,000 shares of the outstanding shares of
 its common stock with all repurchases under the stock repurchase program to be made by December 31, 2025. The Company may repurchase shares of its common stock from
 time to time to mitigate the potential dilutive effects of stock-based incentive plans and other potential uses of common stock for corporate purposes. As of December 31, 2023, there were 2,000,000 shares available for repurchase under this plan which is set to expire on
 December 31, 2025.

 15. Regulatory Capital Requirements

 The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital
 requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the consolidated financial statements. Under capital adequacy guidelines and the
 regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of NBT Bank's assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting
 practices. The capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.

 Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the
 table below) of total and Tier 1 Capital to risk-weighted assets and of Tier 1 capital to average assets. In addition to maintaining minimum capital ratios, the
 Company is subject to a capital conservation buffer ("Buffer") of 2.50% above the minimum to avoid restriction on capital distributions and discretionary bonus paychecks to officers. At December 31, 2023 and 2022, the Company and the Bank meet all capital adequacy requirements to which they were subject.

 Under their prompt corrective action regulations, regulatory authorities are required to take certain supervisory actions (and may take additional discretionary actions)
 with respect to an undercapitalized institution. Such actions could have a direct material effect on an institution's financial statements. The regulations establish a framework for the classification of banks into five categories: well-capitalized,
 adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized. As of December 31, 2023 and 2022, the most recent notifications from the Bank's regulators categorized the Bank as well-capitalized under the regulatory framework for prompt
 corrective action. To be categorized as well-capitalized the Bank must maintain minimum total risk-based, Tier 1 risk-based and Tier 1 Capital to Average Asset ratios as set forth in the table below. There are no conditions or events since that
 notification that management believes have changed the Bank's category.

 Table

 In Mar ch 2020, the OCC, the Board of Governors of the Federal Reserve System and the Federal Deposit Insurance
 Corporation ("FDIC") announced an interim final rule to delay the estimated impact on regulatory capital stemming from the implementation of CECL. Under the modified CECL transition provision, the regulatory capital impact of the
 January 1, 2020 CECL adoption date adjustment to the allowance for credit losses (after-tax) has been deferred and will phase into regulatory capital at 25% per year commencing January 1, 2022. For the ongoing impact of CECL, the Company is
 allowed to defer the regulatory capital impact of the allowance for credit losses in an amount equal to 25% of the change in the allowance for credit losses (pre-tax) recognized through earnings for each period between January 1, 2020 and
 December 31, 2021. The cumulative adjustment to the allowance for credit losses between January 1, 2020 and December 31, 2021, will also phase into regulatory capital at 25% per year commencing January 1, 2022. The Company adopted the capital
 transition relief over the permissible five-year period. The Company and NBT Bank's actual capital amounts and ratios are presented as follows:

 18. Commitments and Contingent Liabilities

 The Company's concentrations of credit risk are reflected in the consolidated balance sheets. The concentrations of credit risk with standby letters of credit, unused
 lines of credit, commitments to originate new loans and loans sold with recourse generally follow the loan classifications.

 At December 31, 2023, approximately 63 % of the Company's
 loans were secured by real estate located in upstate New York, northeastern Pennsylvania, western Massachusetts, southern New Hampshire, Vermont, southern Maine and central and northwestern Connecticut. Accordingly, the ultimate collectability of a
 substantial portion of the Company's portfolio is susceptible to changes in market conditions of those areas. Management is not aware of any material concentrations of credit to any industry or individual borrowers.

 The Company is a party to certain financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These
 financial instruments include commitments to extend credit, unused lines of credit, standby letters of credit and certain agricultural real estate loans sold to investors with recourse, with the sold portion having a government guarantee that is
 assignable back to the Company upon repurchase of the loan in the event of default. The Company's exposure to credit loss in the event of nonperformance by the other party to the commitments to extend credit, unused lines of credit, standby letters
 of credit and loans sold with recourse is represented by the contractual amount of those instruments. The credit risk associated with commitments to extend credit and standby and commercial letters of credit is essentially the same as that involved
 with extending loans to customers and is subject to normal credit policies. Collateral may be obtained based on management's assessment of the customer's creditworthiness.

 Since many loan commitments, standby letters of credit and guarantees and indemnification contracts expire without being funded in whole or in part, the contract amounts
 are not necessarily indicative of future cash flows. The Company does not issue any guarantees that would require liability-recognition or disclosure, other than its standby letters of credit.

 Table

 The Company guarantees the obligations or performance of customers by issuing standby letters of credit to third-parties. These standby letters of
 credit are generally issued in support of third-party debt, such as corporate debt issuances, industrial revenue bonds and municipal securities. The risk involved in issuing standby letters of credit is essentially the same as the credit risk
 involved in extending loan facilities to customers and letters of credit are subject to the same credit origination, portfolio maintenance and management procedures in effect to monitor other credit and off-balance sheet products. Typically, these
 instruments have one year expirations with an option to renew upon annual review; therefore, the total amounts do not necessarily
 represent future cash requirements. As of December 31, 2023 and 2022, the fair value of the Company's standby letters of credit was not significant.

 In the normal course of business there are various outstanding legal proceedings. If legal costs are deemed material by management, the Company accrues for the estimated
 loss from a loss contingency if the information available indicates that it is probable that a liability had been incurred at the date of the financial statements and the amount of loss can be reasonably estimated.

 The Company is required to maintain reserve balances with the Federal Reserve Bank. The required average total reserve for NBT Bank for the 14 -day maintenance period ending December 28, 2023 was $ 99.6
 million.

 19. Derivative Instruments and Hedging Activities

 The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide
 variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, primarily by managing the amount, sources and duration of its assets and liabilities and
 through the use of derivative instruments. Specifically, the Company may enter into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash
 amounts, the value of which are determined by interest rates. Generally, the Company may use derivative financial instruments to manage differences in the amount, timing and duration of the Company's known or expected cash receipts and its known or
 expected cash payments. Currently, the Company has interest rate derivatives that result from a service provided to certain qualifying customers and, therefore, are not used to manage interest rate risk in the Company's assets or liabilities. The
 Company manages a matched book with respect to its derivative instruments in order to minimize its net risk exposure resulting from such transactions.

 Derivatives Not Designated as Hedging Instruments

 The
 Company enters into interest rate swaps to facilitate customer transactions and meet their financing needs. These swaps are considered derivatives, but are not designated in hedging relationships. These instruments have interest rate and credit
 risk associated with them. To mitigate the interest rate risk, the Company enters into offsetting interest rate swaps with counterparties. The counterparty swaps are also considered derivatives and are also not designated in hedging
 relationships. Interest rate swaps are recorded within other assets or other liabilities on the consolidated balance sheets at their estimated fair value. Changes to the fair value of assets and liabilities arising from these derivatives are
 included, net, in other operating income in the consolidated statements of income.

 The Company is subject
 to over-the-counter derivative clearing requirements, which require certain derivatives to be cleared through central clearing houses. Accordingly, the Company clears certain derivative transactions through the Chicago Mercantile Exchange Clearing
 House ("CME"). The CME requires the Company to post initial and variation margin payments to mitigate the risk of non-payment, the latter of which is received or paid daily based on the net asset or liability position of the contracts. A daily
 settlement occurs through the CME for changes in the fair value of centrally cleared derivatives. Not all of the derivatives are required to be cleared through the daily clearing agent. As a result, the total fair values of loan level derivative
 assets and liabilities recognized on the Company's financial statements are not equal and offsetting.

 In 2017, the U.K. Financial Conduct Authority
 announced its intention to stop compelling banks to submit rates for the calculation of London Interbank Offered Rate ("LIBOR") after 2021. In 2022, the Federal Reserve adopted a final rule implementing the Adjustable Interest Rate (LIBOR) Act by
 identifying benchmark rates based on the Secured Overnight Financing Rate ("SOFR") that replaced LIBOR in certain financial contracts after June 30, 2023. As of December 31, 2023, the Company has transitioned all of its financial instruments to
 an alternative benchmark rate.

 As of December 31, 2023 and 2022, the Company had twelve
 and fifteen risk participation agreements, respectively, with financial institution counterparties for interest rate swaps related to
 participated loans. Risk participation agreements provide credit protection to the financial institution that originated the swap transaction should the borrower fail to perform on its obligation. The Company enters into both risk participation
 agreements in which it purchases credit protection from other financial institutions and those in which it provides credit protection to other financial institutions.

 Derivatives Designated as Hedging Instruments

 The Company has previously entered into interest rate swaps to modify the interest rate characteristics of certain short-term FHLB advances from variable rate to fixed
 rate in order to reduce the impact of changes in future cash flows due to market interest rate changes. These agreements are designated as cash flow hedges with currently none outstanding.

 (1)

 Netting adjustments represents the amounts recorded to convert
 derivatives assets and liabilities from a gross basis to a net basis in accordance with the applicable accounting guidance on the settle to market rules for cleared derivatives. The CME legally characterizes the variation margin posted
 between counterparties as settlements of the outstanding derivative contracts instead of cash collateral.

 (2)

 Cash collateral represents the amount that cannot be used to offset our
 derivative assets and liabilities from a gross basis to a net basis in accordance with the applicable accounting guidance. The other collateral consists of securities and is exchanged under bilateral collateral and master netting agreements
 that allow us to offset the net derivative position with the related collateral. The application of the other collateral cannot reduce the net derivative position below zero. Therefore, excess other collateral, if any, is not reflected
 above.

 For derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in AOCI and subsequently
 reclassified into interest expense in the same period during which the hedge transaction affects earnings. Amounts reported in AOCI related to derivatives will be reclassified to interest expense as interest payments are made on the Company's
 short-term rate borrowings. During 2021 the Company's final cash flow hedge of interest rate risk matured and the remaining balance was reclassified from AOCI as a reduction to interest expense. There is no additional amount that will be reclassified from AOCI as a reduction to interest expense.

 20. Fair Value Measurements and Fair Values of Financial Instruments

 GAAP states that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction
 between market participants. Fair value measurements are not adjusted for transaction costs. A fair value hierarchy exists within GAAP that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest
 priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described
 below:

 Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

 Level 2 - Quoted prices for similar assets or liabilities in active markets, quoted prices in markets that are not active or inputs that are observable, either
 directly or indirectly, for substantially the full term of the asset or liability; and

 Level 3 - Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no
 market activity).

 A financial instrument's level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.

 The types of instruments valued based on quoted market prices in active markets include most U.S. government and agency securities, many other sovereign government
 obligations, liquid mortgage products, active listed equities and most money market securities. Such instruments are generally classified within Level 1 or Level 2 of the fair value hierarchy. The Company does not adjust the quoted prices for such
 instruments.

 The types of instruments valued based on quoted prices in markets that are not active, broker or dealer quotations or quote from alternative pricing sources with
 reasonable levels of price transparency include most investment-grade and high-yield corporate bonds, less liquid mortgage products, less liquid agency securities, less liquid listed equities, state, municipal and provincial obligations and certain
 physical commodities. Such instruments are generally classified within Level 2 of the fair value hierarchy. Certain common equity securities are reported at fair value utilizing Level 1 inputs (exchange quoted prices). Other investment securities
 are reported at fair value utilizing Level 1 and Level 2 inputs. The prices for Level 2 instruments are obtained through an independent pricing service or dealer market participants with whom the Company has historically transacted both purchases
 and sales of investment securities. Prices obtained from these sources include prices derived from market quotations and matrix pricing. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash
 flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond's terms and conditions, among other things. Management reviews the methodologies used by its
 third-party providers in pricing the securities.

 Level 3 is for positions that are not traded in active markets or are subject to transfer restrictions. Valuations are adjusted to reflect illiquidity and/or
 non-transferability and such adjustments are generally based on available market evidence. In the absence of such evidence, management's best estimate will be used. Management's best estimate consists of both internal and external support on
 certain Level 3 investments. Subsequent to inception, management only changes Level 3 inputs and assumptions when corroborated by evidence such as transactions in similar instruments, completed or pending third-party transactions in the underlying
 investment or comparable entities, subsequent rounds of financing, recapitalizations and other transactions across the capital structure, offerings in the equity or debt markets and changes in financial ratios or cash flows.

 GAAP requires disclosure of assets and liabilities measured and recorded at fair
 value on a non-recurring basis such as goodwill, loans held for sale, other real estate owned, collateral-dependent loans individually evaluated for expected credit losses and HTM securities. The non-recurring fair value measurements recorded
 during the years ended December 31, 2023 and 2022 were related to loans individually evaluated for expected credit losses. Loans with fair value of $ 1.1
 million as of December 31, 2022 were individually evaluated for expected credit losses where the amortized cost was adjusted to fair value. There were no
 loans individually evaluated expected credit losses where the amortized cost was adjusted to fair value for the year ended December 31, 2023. The Company uses the fair value of underlying collateral, less costs to sell, to estimate the allowance
 for credit losses for individually evaluated collateral dependent loans. The appraisals may be adjusted by management for qualitative factors such as economic conditions and estimated liquidation expenses ranging from 10 % to 50 %. Based on the valuation
 techniques used, the fair value measurements for collateral dependent individually evaluated loans are classified as Level 3.

 The following table sets forth information with regard to estimated fair values of financial instruments. This table excludes financial instruments for which the
 carrying amount approximates fair value. Financial instruments for which the fair value approximates carrying value include cash and cash equivalents, AFS securities, equity securities, accrued interest receivable, non-maturity deposits, short-term
 borrowings, accrued interest payable and derivatives.

 Table

 Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not
 reflect any premium or discount that could result from offering for sale at one time the Company's entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company's financial instruments, fair
 value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments and other factors. These estimates are subjective in nature and involve
 uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

 Fair value estimates are based on existing on and off-balance sheet financial instruments without attempting to estimate the value of anticipated future business and
 the value of assets and liabilities that are not considered financial instruments. For example, the Company has a substantial wealth operation that contributes net fee income annually. The wealth management operation is not considered a financial
 instrument and its value has not been incorporated into the fair value estimates. Other significant assets and liabilities include the benefits resulting from the low-cost funding of deposit liabilities as compared to the cost of borrowing funds in
 the market and premises and equipment. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimate of fair
 value.

 HTM Securities

 The fair value of the Company's HTM securities is primarily measured using information from a third-party pricing service. The fair value measurements consider
 observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond's terms and conditions, among
 other things.

 Net Loans

 Net loans include portfolio loans and loans held for sale. Loans were first segregated by type and then further segmented into fixed and variable
 rate and loan quality categories. Expected future cash flows were projected based on contractual cash flows, adjusted for estimated prepayments, and those expected future cash flows also include credit risk, illiquidity risk and other market
 factors to calculate the exit price fair value in accordance with ASC 820.

 Time Deposits

 The fair value of time deposits was estimated using a discounted cash flow approach that applies prevailing market interest rates for similar maturity instruments. The
 fair values of the Company's time deposit liabilities do not take into consideration the value of the Company's long-term relationships with depositors, which may have significant value.

 Long-Term Debt

 The fair value of long-term debt was estimated using a discounted cash flow approach that applies prevailing market interest rates for similar maturity instruments.

 Subordinated Debt

 The fair value of subordinated debt has been measured using the observable market price as of the period reported.

 Junior Subordinated Debt

 The fair value of junior subordinated debt has been estimated using a discounted cash flow analysis.

 ITEM 9A.

 CONTROLS AND PROCEDURES

 As of the end of the period covered by this Annual Report on Form 10-K, an evaluation was carried out by the Company's management, with the participation of its Chief Executive Officer and Chief
 Financial Officer, of the effectiveness of the Company's disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934). Based upon that evaluation, the Chief Executive Officer and Chief Financial
 Officer concluded that the disclosure controls and procedures were effective as of the end of the period covered by this report. No changes were made to the Company's internal control over financial reporting that occurred during the period
 covered by this report that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

 Management Report on Internal Control Over Financial Reporting

 The management of NBT Bancorp Inc. (the "Company") is responsible for establishing and maintaining adequate internal control over financial reporting. The Company's internal control over financial
 reporting is a process designed under the supervision of the Company's Chief Executive Officer and Chief Financial Officer to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the Company's
 consolidated financial statements for external purposes in accordance with generally accepted accounting principles.

 As of December 31, 2023, management assessed the effectiveness of the Company's internal control over financial reporting based on the criteria for effective internal control over financial
 reporting established in "Internal Control – Integrated Framework (2013)," issued by the Committee of Sponsoring Organizations ("COSO") of the Treadway Commission. Based on the assessment, management
 determined that the Company's internal control over financial reporting as of December 31, 2023 was effective at the reasonable assurance level based on those criteria.

 KPMG LLP, the independent registered public accounting firm that audited the consolidated financial statements of the Company included in this Annual Report on Form 10-K, has issued a report on
 the effectiveness of the Company's internal control over financial reporting as of December 31, 2023. The report, which expresses an unqualified opinion on the effectiveness of the Company's internal control over financial reporting as of
 December 31, 2023, is included in this Item under the heading "Report of Independent Registered Public Accounting Firm" on the following page.

 Report of Independent Registered Public Accounting Firm

 To the Stockholders and Board of Directors

 NBT Bancorp Inc.:

 Opinion on Internal Control Over Financial Reporting

 We have audited NBT Bancorp Inc. and subsidiaries' (the Company) internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over
 financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway
 Commission.

 We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31,
 2023 and 2022, the related consolidated statements of income, comprehensive income (loss), changes in stockholders' equity, and cash flows for each of the years in the three-year period ended December 31, 2023, and the related notes
 (collectively, the consolidated financial statements), and our report dated February 29, 2024 expressed an unqualified opinion on those consolidated financial statements.

 Basis for Opinion

 The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial
 reporting, included in the accompanying Management Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public
 accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and
 the PCAOB.

 We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal
 control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a
 material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the
 circumstances. We believe that our audit provides a reasonable basis for our opinion.

 Definition and Limitations of Internal Control Over Financial Reporting

 A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial
 statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in
 reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in
 accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance
 regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

 Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are
 subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
