 EXPLANATORY NOTES

 The Prudential Plaza Mortgage Loan, which
constituted approximately 10.5% of the asset pool of the issuing entity as of
its cut-off date, is an asset of the issuing entity and is part of a loan
combination that includes the Prudential Plaza Mortgage Loan and three other pari
passu loans, which are not assets of the issuing entity. This loan
combination, including the Prudential Plaza Mortgage Loan, is being serviced and
administered pursuant to the Pooling and Servicing Agreement, which is
incorporated by reference as Exhibit 4.1 to this Annual Report on Form 10-K.

 The Exhibit Index describes
exhibits provided by certain parties (in their capacities indicated on the Exhibit
Index) with respect to the Heartland Industrial Portfolio Mortgage Loan, which
constituted approximately 3.2% of the asset pool of the issuing entity as of
its cut-off date. The Heartland Industrial Portfolio Mortgage Loan is an
asset of the issuing entity and is part of a loan combination that includes the
Heartland Industrial Portfolio Mortgage Loan and two other pari passu
loans, which are not assets of the issuing entity. A pari passu portion
of the loan combination was securitized in the COMM 2015-CCRE25 Mortgage Trust
transaction, Commission File Number 333-193376-22 (the " COMM 2015-CCRE25
Transaction "). This loan combination, including the Heartland Industrial
Portfolio Mortgage Loan, is being serviced and administered pursuant to the
pooling and servicing agreement for the COMM 2015-CCRE25 Transaction, which is
incorporated by reference as Exhibit 4.2 to this Annual Report on Form 10-K.

 The Exhibit Index describes
exhibits provided by certain parties (in their capacities indicated on the Exhibit
Index) with respect to the 11 Madison Avenue Mortgage Loan, which constituted
approximately 6.4% of the asset pool of the issuing entity as of its cut-off
date. The 11 Madison Avenue Mortgage Loan is an asset of the issuing
entity and is part of a loan combination that includes the 11 Madison Avenue
Mortgage Loan, fifteen other pari passu loans and three subordinate
companion loans, which are not assets of the issuing entity. A pari passu
portion of the loan combination was securitized in the MAD 2015-11MD Mortgage
Trust transaction (the " MAD 2015-11MD Transaction "). This loan
combination, including the 11 Madison Avenue Mortgage Loan, is being serviced
and administered pursuant to the trust and servicing agreement for the MAD
2015-11MD Transaction, which is incorporated by reference as Exhibit 4.3 to
this Annual Report on Form 10-K.

 The master servicer of a pooling
and servicing agreement or trust and servicing agreement also functions as the
primary servicer of the related mortgage loans serviced and administered
pursuant to such agreement unless a separate primary servicer is identified
herein. If this report does not identify a separate primary servicer, the
servicer compliance statement provided by the master servicer under any such
agreement also encompasses its responsibilities as primary servicer of the
related mortgage loan or mortgage loans.

 Wells Fargo Bank, National
Association is the master servicer and certificate administrator of the
mortgage loans serviced under the Pooling and Servicing Agreement and the
primary servicer of the Heartland Industrial Portfolio Mortgage Loan. As a
result, Wells Fargo Bank, National Association is a "servicer" as defined in
Item 1108(a)(2)(iii) of Regulation AB, in the capacities described above,
because it is servicing mortgage loans that constituted 10% or more of the
assets of the issuing entity as of its cut-off date. The assessments of
compliance with applicable servicing criteria, accountants' attestation reports
and servicer compliance statements delivered by Wells Fargo Bank, National
Association in the capacities described above are listed in the Exhibit Index.

 Berkeley Point Capital LLC d/b/a
Newmark is an affiliate of Cantor Commercial Real Estate Lending L.P., one of
the sponsors. Therefore, the Depositor included in this Annual Report on
Form 10-K a servicer compliance statement for Berkeley Point Capital LLC d/b/a
Newmark pursuant to Item 1123. Because Berkeley Point Capital LLC d/b/a
Newmark is servicing less than 5% of the pool assets, an assessment of
compliance with applicable servicing criteria and an accountants' attestation
report pursuant to Item 1122 of Regulation AB are not required by Regulation
AB. As the attestation made in the servicer compliance statement required
by Item 1123 relates to a review of the servicing activities of Berkeley Point
Capital LLC d/b/a Newmark under the applicable servicing agreement, and that
review was conducted in conjunction with the servicer's preparation of its
assessment of compliance with applicable servicing criteria, that assessment of
compliance with applicable servicing criteria and the accompanying accountants'
attestation report are included in this Annual Report on Form 10-K for the sake
of completeness.

 Wilmington Trust, National
Association acts as trustee of the mortgage loans serviced under the
Pooling and Servicing Agreement, the Heartland Industrial Portfolio Mortgage
Loan and the 11 Madison Avenue Mortgage Loan. Pursuant to the Pooling and
Servicing Agreement, the pooling and servicing agreement for the COMM
2015-CCRE25 Transaction and the trust and servicing agreement for the MAD
2015-11MD Transaction, the trustee is required to provide an assessment of
compliance with applicable servicing criteria solely with respect to Item
1122(d)(2)(iii) of Regulation AB (regarding advances of funds or guarantees
regarding collections, cash flows or distributions, and any interest or other
fees charged for such advances, are made, reviewed and approved as specified in
the transaction agreements). However, during the reporting period, the trustee
did not perform any servicing function with respect to the servicing criteria
specified in Item 1122(d)(2)(iii) of Regulation AB. The master servicer
or the special servicer, to the extent required, performed the servicing
function identified with respect to Item 1122(d)(2)(iii) of Regulation AB, and
each such party included Item 1122(d)(2)(iii) of Regulation AB in the
assessment of compliance with applicable servicing criteria and accountant's
attestation report for the subject transaction. As a result, this Annual
Report on Form 10-K does not include an assessment of compliance with
applicable servicing criteria of the trustee. One or more other servicers
of the mortgage loans serviced under the Pooling and Servicing Agreement,
the Heartland Industrial Portfolio Mortgage Loan and the 11 Madison Avenue
Mortgage Loan have delivered one or more assessments of compliance with respect
to Item 1122(d)(2)(iii) of Regulation AB.

 This Annual Report on Form 10-K
includes assessments of compliance with applicable servicing criteria and
accountants' attestation reports from CoreLogic Solutions, LLC. This
entity was engaged by the master servicer under the Pooling and Servicing
Agreement (except with respect to those mortgage loans for which Berkeley Point
Capital LLC d/b/a Newmark is the primary servicer) and the primary
servicer of the Heartland Industrial Portfolio Mortgage Loan to remit tax
payments received from the escrow accounts of borrowers to local taxing authorities,
to report tax amounts due, to verify tax parcel information, and to verify
non-escrow tax payments. These servicing functions are included within the
servicing criteria set forth in Items 1122(d)(4)(xi) and 1122(d)(4)(xii) of
Regulation AB. Therefore, under the principles-based definition of
"servicer" set forth in Item 1101(j) of Regulation AB that looks to the
functions that an entity performs, this vendor is a "servicer" for the purposes
of Item 1122 of Regulation AB. See Compliance and Disclosure
Interpretations, Section 301.01 (Item 1101(j)).

 This Annual Report on Form 10-K
includes an assessment of compliance with applicable servicing criteria,
accountants' attestation report and servicer compliance statement from
Computershare Trust Company, National Association (" CTCNA "). CTCNA
was engaged by Wells Fargo Bank, National Association (" Wells Fargo "),
in its capacity as certificate administrator and custodian, to perform certain
specified servicing functions identified in the assessment of compliance with
applicable servicing criteria and accountants' attestation reports. Wells
Fargo engaged CTCNA in connection with the sale of Wells Fargo's corporate trust
services business to CTCNA and its affiliates. Further, under the
principles-based definition of "servicer" set forth in Item 1101(j) of
Regulation AB that looks to the functions that an entity performs, this party
is a "servicer" for the purposes of Item 1123 of Regulation AB. See
Compliance and Disclosure Interpretations, Section 301.01 (Item 1101(j)).

 The
assessments of compliance with applicable servicing criteria, accountants'
attestation reports and servicer compliance statements of the certificate administrator
of the 11 Madison Avenue Mortgage Loan and the Heartland Industrial Portfolio
Mortgage Loan are omitted from this Annual Report on Form 10-K as the
certificate administrator pursuant to the related pooling and servicing
agreement or trust and servicing agreement does not perform any activities that
address servicing criteria with respect to the issuing entity and because they
are each not a "servicer" that meets the criteria in Item 1108(a)(2)(i) through
(iii) of Regulation AB.

 With respect to the pari passu
loan combinations that include the Heartland Industrial Portfolio Mortgage Loan
and the 11 Madison Avenue Mortgage Loan, (i) the reports on assessment of
compliance with servicing criteria and attestation reports on assessment of
compliance with servicing criteria of LNR Partners, LLC as special servicer of
the Heartland Industrial Portfolio Mortgage Loan, Deutsche Bank Trust Company
Americas as custodian of the Heartland Industrial Portfolio Mortgage Loan and
Pentalpha Surveillance LLC as operating advisor of the Heartland Industrial
Portfolio Mortgage Loan, listed on the Exhibit Index are omitted from this
Annual Report on Form 10-K as they are not required to be included on this
Annual Report on Form 10-K per Instruction 3 to Item 1122 of Regulation AB
because they are parties performing activities that address servicing criteria
relating to 5% or less of the assets of the issuing entity; and (ii) the
servicer compliance statements of LNR Partners, LLC as special servicer of the
Heartland Industrial Portfolio Mortgage Loan and KeyBank National Association
as primary servicer and special servicer of the 11 Madison Avenue Mortgage
Loan, listed on the Exhibit Index are omitted from this Annual Report on Form
10-K as they are not required by Item 1123 of Regulation AB to be included on
this Annual Report on Form 10-K because they are each an unaffiliated party
that is not a "servicer" that meets the criteria in Item 1108(a)(2)(i) through
(iii) of Regulation AB.

 No entity or group of affiliated entities provides any

 Item 1117 of Regulation AB, Legal Proceedings.

 The registrant knows of no
material pending legal proceeding involving the trust or any party related to
the trust, other than routine litigation incidental to the duties of those
respective parties, and the following, with respect to Wells Fargo Bank,
National Association, as certificate administrator and as custodian, and
Deutsche Bank Trust Company Americas, as certificate administrator and as
custodian.

 In December 2014, Phoenix Light SF Limited (Phoenix
Light) and certain related entities filed a complaint in the United States
District Court for the Southern District of New York alleging claims against
Wells Fargo Bank, N.A., in its capacity as trustee for a number of residential
mortgage-backed securities (RMBS) trusts. Complaints raising similar
allegations have been filed by Commerzbank AG in the Southern District of New
York, IKB International and IKB Deutsche Industriebank (together, IKB) in New
York state court, and Park Royal I LLC and Park Royal II LLC in New York state
court. In each case, the plaintiffs allege that Wells Fargo Bank, N.A., as
trustee, caused losses to investors, and plaintiffs assert causes of action
based upon, among other things, the trustee's alleged failure to notify and
enforce repurchase obligations of mortgage loan sellers for purported breaches
of representations and warranties, notify investors of alleged events of
default, and abide by appropriate standards of care following alleged events of
default. In July 2022, the district court dismissed Phoenix Light's claims and
certain of the claims asserted by Commerzbank AG, and subsequently entered
judgment in each case in favor of Wells Fargo Bank, N.A. In August 2022,
Phoenix Light and Commerzbank AG each appealed the district court's decision to
the United States Court of Appeals for the Second Circuit. Phoenix Light
dismissed its appeal in May 2023, terminating its case. In November 2023, Wells
Fargo Bank, N.A. entered into an agreement with IKB to resolve IKB's claims.
Wells Fargo Bank, N.A. previously settled two class actions filed by
institutional investors and an action filed by the National Credit Union
Administration with similar allegations.

 Deutsche Bank Trust Company Americas ("DBTCA") and Deutsche
Bank National Trust Company ("DBNTC") have been sued by investors in civil
litigation concerning their role as trustees of certain residential
mortgage-backed securities ("RMBS") trusts.

 On June 18, 2014, a group of investors, including funds
managed by Blackrock Advisors, LLC, PIMCO-Advisors, L.P., and others, filed an
action against DBNTC and DBTCA in New York State Supreme Court alleging that
DBNTC and DBTCA failed to perform purported duties, as trustees for 544
private-label RMBS trusts, to enforce breaches of representations and
warranties as to mortgage loans held by the trusts and to enforce breaches by
servicers of their mortgage loan servicing obligations for the trusts. During
the course of the litigation, plaintiffs dismissed the case from New York State
Supreme Court and refiled two separate cases, one in the U.S. District Court
for the Southern District of New York (the "BlackRock SDNY Case") and the other
in the Superior Court of California, Orange County (the "BlackRock California
Case"). Pursuant to a settlement among the parties, the BlackRock SDNY
Case was dismissed on December 6, 2018, and the BlackRock California Case was
dismissed on January 11, 2019.

 On September 27, 2017, DBTCA was added as a defendant to a
case brought by certain special purpose entities including Phoenix Light SF
Limited in the U.S. District Court for the Southern District of New York, in
which the plaintiffs previously alleged incorrectly that DBNTC served as
trustee for all 43 of the trusts at issue. On September 27, 2017,
plaintiffs filed a third amended complaint that names DBTCA as a defendant in
addition to DBNTC. DBTCA serves as trustee for one of the 43 trusts at
issue. DBNTC serves as trustee for the other 42 trusts at issue.
Plaintiffs' third amended complaint brings claims for violation of the U.S.
Trust Indenture Act of 1939 ("TIA"); breach of contract; breach of fiduciary
duty; negligence and gross negligence; violation of New York's Streit Act; and
breach of the covenant of good faith. However, in the third amended
complaint, plaintiffs acknowledge that, before DBTCA was added to the case, the
court dismissed plaintiffs' TIA Act claims, negligence and gross negligence
claims, Streit Act claims, claims for breach of the covenant of good faith, and
certain theories of plaintiffs' breach of contract claims, and plaintiffs only
include these claims to preserve any rights on appeal. Plaintiffs allege
damages of "hundreds of millions of dollars." On November 13, 2017, DBNTC
and DBTCA filed an answer to the third amended complaint. On December 7,
2018, DBNTC and DBTCA filed a motion for summary judgment. Also on
December 7, 2018, plaintiffs, jointly with Commerzbank AG (see description of
Commerzbank case below), filed a motion for partial summary judgment. On
October 27, 2021, DBNTC and DBTCA filed a supplemental motion for summary
judgment relating to plaintiffs' standing. On February 8, 2022, the court
issued an order in which it granted DBNTC and DBTCA's supplemental motion for
summary judgment, granted in part DBNTC and DBTCA's initial motion for summary
judgment, and denied plaintiffs' motion for partial summary judgment. As
a result of that order, all of plaintiffs' claims were dismissed with
prejudice. On April 26, 2023, the United States Court of Appeals for the Second
Circuit affirmed the court's summary judgment order.

 On November 30, 2017, DBTCA was added as a defendant to a
case brought by Commerzbank AG ("Commerzbank") in the U.S. District Court for
the Southern District of New York, in which Commerzbank previously alleged
incorrectly that DBNTC served as trustee for all 50 of the trusts at
issue. On November 30, 2017, Commerzbank filed a second amended complaint
that names DBTCA as a defendant in addition to DBNTC. DBTCA serves as
trustee for 1 of the 50 trusts at issue. DBNTC serves as trustee for the
other 49 trusts at issue. Commerzbank's second amended complaint brings
claims for violation of the TIA; breach of contract; breach of fiduciary duty;
negligence; violation of the Streit Act; and breach of the covenant of good
faith. However, in the second amended complaint, Commerzbank acknowledges
that, before DBTCA was added to the case, the court dismissed Commerzbank's TIA
claims for the trusts governed by pooling and servicing agreements, as well as
its Streit Act claims and claims for breach of the covenant of good faith, and
Commerzbank only includes these claims to preserve any rights on appeal.
The second amended complaint alleges that DBNTC and DBTCA caused Commerzbank to
suffer "hundreds of millions of dollars in losses," but the complaint does not
include a demand for money damages in a sum certain. On January 29, 2018,
DBNTC and DBTCA filed an answer to the second amended complaint. On
December 7, 2018, DBNTC and DBTCA filed a motion for summary judgment.
Also on December 7, 2018, Commerzbank, jointly with the Phoenix Light
plaintiffs, filed a motion for partial summary judgment. On February 8,
2022, the court issued an order in which it granted in part DBNTC and DBTCA's
motion for summary judgment and denied plaintiffs' motion for partial summary
judgment. As a result of that order, many of plaintiffs' claims and
theories were dismissed with prejudice. Discovery is ongoing.

 On December 30, 2015, IKB International, S.A. in Liquidation
and IKB Deutsche Industriebank A.G. (collectively, "IKB"), as an investor in 37
RMBS trusts, filed a summons with notice in the Supreme Court of the State of
New York, New York County, against DBNTC and DBTCA as trustees of the
trusts. On May 27, 2016, IKB served its complaint asserting claims for
breach of contract, breach of fiduciary duty, breach of duty to avoid conflicts
of interest, violation of the Streit Act, violation of the TIA, violation of
Regulation AB, and violation of Section 9 of the Uniform Commercial Code.
IKB alleges that DBNTC and DBTCA are liable for over U.S. $268 million in
damages. On October 5, 2016, DBNTC and DBTCA, together with several other
trustees defending lawsuits by IKB, filed a joint motion to dismiss. On
January 6, 2017 and June 20, 2017, IKB voluntarily dismissed with prejudice all
claims as to seven trusts. On January 27, 2021, the court granted in part
and denied in part DBNTC and DBTCA's motion to dismiss. The court granted
the motion to dismiss with respect to IKB's claims for violations of the Streit
Act, Regulation AB, and Section 9 of the Uniform Commercial Code, as well as
certain aspects of IKB's claims for breach of contract, breach of fiduciary
duty, and violation of the TIA. The court denied the remainder of the
motion to dismiss. IKB's remaining claims for breach of contract, breach
of fiduciary duty, breach of duty to avoid conflicts of interest, and violation
of the TIA will proceed. On May 10, 2021, DBNTC and DBTCA filed a notice
of appeal with the New York Supreme Court Appellate Division, First Department,
regarding certain aspects of the court's order on the motion to dismiss.
On May 20, 2021, IKB filed a notice of cross appeal with respect to other
aspects of that order. On August 30, 2022, the New York Supreme Court,
Appellate Division, First Department affirmed in part and reversed in part the
court's order on the motion to dismiss. After DBNTC and DBTCA appealed
the First Department's decision, on June 15, 2023, the New York Court of
Appeals reversed the First Department's decision in part, dismissing certain
additional contract claims, as well as IKB's claims for breach of fiduciary
duty and breach of duty to avoid conflicts of interest. On June 2, 2021,
IKB filed a motion for re-argument regarding certain aspects of the court's
order on the motion to dismiss, which the court denied on August 3, 2021.
On May 13, 2021, DBNTC and DBTCA filed an answer to the complaint. On
October 28, 2021, the parties filed a stipulation, voluntarily dismissing with
prejudice all claims as to seven additional trusts. On December 29, 2021,
the parties filed a stipulation, voluntarily dismissing with prejudice all
claims as to one additional trust. On April 22, 2022, the parties filed a
stipulation, voluntarily dismissing with prejudice all claims as to 17
certificates at issue, including all claims as to 5 trusts. On February
28, 2023, the parties filed a stipulation, voluntarily dismissing with
prejudice all claims as to two trusts, leaving 15 trusts at issue. On
November 21, 2023, the parties filed a stipulation, voluntarily dismissing with
prejudice all claims as to three trusts, leaving 12 trusts at issue.
Discovery is ongoing.

 It is DBTCA's belief that it has no pending legal
proceedings (including, based on DBTCA's present evaluation, the litigation
disclosed in the foregoing paragraphs) that would materially affect its ability
to perform its duties under the related servicing agreement for this
transaction.

 Item 1119 of Regulation AB, Affiliations and Certain
Relationships and Related Transactions.

 The information regarding this Item has been previously
provided in a prospectus supplement of the Registrant relating to the issuing
entity filed on October 7, 2015 pursuant to Rule 424(b)(5).

 Item 1122 of Regulation AB, Compliance with Applicable
Servicing Criteria.

 The reports on assessments of compliance with the servicing
criteria for asset-backed securities and related attestation reports on such
assessments of compliance with respect to the mortgage loans are attached

Mortgage Loan, which is being serviced and administered pursuant to the pooling

Mortgage Loan. As a result, Midland Loan Services, a Division of PNC Bank, National
Association is a "servicer" as defined in Item 1108(a)(2)(iii) of Regulation
AB, in the capacities described above, because it is servicing mortgage loans
that constituted 10% or more of the assets of the issuing entity as of its
cut-off date. The assessments of compliance with applicable servicing criteria,
accountants' attestation reports and servicer compliance statements delivered
by Midland Loan Services, a Division of PNC Bank, National Association in the
capacities described above are listed in the Exhibit Index.

 3650 REIT Loan Servicing LLC is
the special servicer of the mortgage loans serviced under the Pooling and
Servicing Agreement, the Selig Office Portfolio Mortgage Loan, the Renaissance
Plano Mortgage Loan and the APX Morristown Mortgage Loan. As a result, 3650

as of its cut-off date. The assessments of compliance with applicable servicing
criteria, accountants' attestation reports and servicer compliance statements
delivered by 3650 REIT Loan Servicing LLC in the capacities described above are

and Servicing Agreement, the Selig Office Portfolio Mortgage Loan, The
Westchester Mortgage Loan, the University Village Mortgage Loan, the Renaissance
Plano Mortgage Loan and the APX Morristown Mortgage Loan. As a result,
Wells Fargo Bank, National Association is a servicing function participant in

Servicing Agreement, the Selig Office Portfolio Mortgage Loan, the University
Village Mortgage Loan, the Renaissance Plano Mortgage Loan and the APX

applicable servicing criteria and accountants' attestation reports delivered by

 Wells Fargo Bank, National
Association acts as trustee of the KPMG Plaza at Hall Arts Mortgage Loan, the
Sol y Luna Mortgage Loan, the Selig Office Portfolio Mortgage Loan, the
Renaissance Plano Mortgage Loan, the APX Morristown Mortgage Loan, the University
Village Mortgage Loan and The Westchester Mortgage Loan. Pursuant to the
Pooling and Servicing Agreement, the pooling and servicing agreement for the
CSAIL 2019-C17 Transaction, the trust and servicing agreement for the CSMC
2019-UVIL Transaction and the trust and servicing agreement for the CSMC
2020-WEST Transaction, the trustee is required to provide an assessment of
compliance with applicable servicing criteria solely with respect to Item
1122(d)(2)(iii) of Regulation AB (regarding advances of funds or guarantees
regarding collections, cash flows or distributions, and any interest or other
fees charged for such advances, are made, reviewed and approved as specified in
the transaction agreements). However, during the reporting period, the trustee did
not perform any servicing function with respect to the servicing criteria
specified in Item 1122(d)(2)(iii) of Regulation AB. The master servicer
or the special servicer, to the extent required, performed the servicing
function identified with respect to Item 1122(d)(2)(iii) of Regulation AB, and
each such party included Item 1122(d)(2)(iii) of Regulation AB in the
assessment of compliance with applicable servicing criteria and accountant's
attestation report for the subject transaction. As a result, this Annual
Report on Form 10-K does not include an assessment of compliance with
applicable servicing criteria of the trustee. One or more other servicers of
the KPMG Plaza at Hall Arts Mortgage Loan, the Sol y Luna Mortgage Loan, the
Selig Office Portfolio Mortgage Loan, the Renaissance Plano Mortgage Loan, the
APX Morristown Mortgage Loan, the University Village Mortgage Loan and The
Westchester Mortgage Loan have delivered one or more assessments of compliance
with respect to Item 1122(d)(2)(iii) of Regulation AB.

 This Annual Report on Form 10-K
includes an assessment of compliance with applicable servicing criteria,
accountants' attestation report and servicer compliance statement from
Computershare Trust Company, National Association (" CTCNA "). CTCNA
was engaged by Wells Fargo Bank, National Association (" Wells Fargo "),
in its capacity as certificate administrator and custodian, to perform certain
specified servicing functions identified in the assessment of compliance with
applicable servicing criteria and accountants' attestation reports. Wells
Fargo engaged CTCNA in connection with the sale of Wells Fargo's corporate
trust services business to CTCNA and its affiliates. Further, under the
principles-based definition of "servicer" set forth in Item 1101(j) of
Regulation AB that looks to the functions that an entity performs, this party
is a "servicer" for the purposes of Item 1123 of Regulation AB. See
Compliance and Disclosure Interpretations, Section 301.01 (Item 1101(j)).

 The
assessments of compliance with applicable servicing criteria, accountants'
attestation reports and servicer compliance statements of the certificate
administrator of the Selig Office Portfolio Mortgage Loan, the Renaissance
Plano Mortgage Loan, the APX Morristown Mortgage Loan, the University Village
Mortgage Loan and The Westchester Mortgage Loan are omitted from this Annual
Report on Form 10-K as the certificate administrator pursuant to the related
pooling and servicing agreement or trust and servicing agreement does not perform
any activities that address servicing criteria with respect to the issuing
entity and because they are each not a "servicer" that meets the criteria in
Item 1108(a)(2)(i) through (iii) of Regulation AB.

 With
respect to the pari passu loan combination that includes the
University Village Mortgage Loan, the servicer compliance statement of Situs
Holdings, LLC, successor to Cohen Financial, a Division of Truist Bank,
successor by merger to SunTrust Bank as special servicer of the University
Village Mortgage Loan listed on the Exhibit Index is omitted from this Annual
Report on Form 10-K as it is not required by Item 1123 of Regulation AB to be
included on this Annual Report on Form 10-K because it is an unaffiliated party
that is not a "servicer" that meets the criteria in Item 1108(a)(2)(i) through
(iii) of Regulation AB.

 Item 1117 of Regulation AB, Legal Proceedings.

 The registrant knows of no material pending legal proceeding
involving the trust or any party related to the trust, other than routine
litigation incidental to the duties of those respective parties, and the
following, with respect to Wells Fargo Bank, National Association, as trustee,
as certificate administrator and as custodian.

 In December 2014, Phoenix Light SF Limited (Phoenix Light)
and certain related entities filed a complaint in the United States District
Court for the Southern District of New York alleging claims against Wells Fargo
Bank, N.A., in its capacity as trustee for a number of residential
mortgage-backed securities (RMBS) trusts. Complaints raising similar
allegations have been filed by Commerzbank AG in the Southern District of New
York, IKB International and IKB Deutsche Industriebank (together, IKB) in New
York state court, and Park Royal I LLC and Park Royal II LLC in New York state
court. In each case, the plaintiffs allege that Wells Fargo Bank, N.A., as
trustee, caused losses to investors, and plaintiffs assert causes of action
based upon, among other things, the trustee's alleged failure to notify and
enforce repurchase obligations of mortgage loan sellers for purported breaches
of representations and warranties, notify investors of alleged events of
default, and abide by appropriate standards of care following alleged events of
default. In July 2022, the district court dismissed Phoenix Light's claims and
certain of the claims asserted by Commerzbank AG, and subsequently entered
judgment in each case in favor of Wells Fargo Bank, N.A. In August 2022,
Phoenix Light and Commerzbank AG each appealed the district court's decision to
the United States Court of Appeals for the Second Circuit. Phoenix Light
dismissed its appeal in May 2023, terminating its case. In November 2023, Wells
Fargo Bank, N.A. entered into an agreement with IKB to resolve IKB's claims.
Wells Fargo Bank, N.A. previously settled two class actions filed by
institutional investors and an action filed by the National Credit Union
Administration with similar allegations.
