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

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

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 and the 245 Park 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

Agreement and the primary servicer of the 245 Park Avenue Mortgage Loan to
remit tax payments received from the escrow accounts of borrowers to local

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

 This Annual
Report on Form 10-K includes an assessment of compliance with applicable

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

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 245 Park Avenue
Mortgage Loan and the Garden Multifamily 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 245 Park Avenue
Mortgage Loan and the Garden Multifamily Portfolio Mortgage Loan, (i) the
report on assessment of compliance with servicing criteria and attestation
report on assessment of compliance with servicing criteria of KeyBank National
Association as primary servicer of the Garden Multifamily 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 it is a party
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 Situs Holdings, LLC as special servicer of the 245 Park Avenue Mortgage Loan
and KeyBank National Association as primary servicer of the Garden Multifamily
Portfolio 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

1108(a)(2)(i) through (iii) of Regulation AB.

 The 85 Broad Street Mortgage Loan
(Loan ID 1 on Annex A-1 of the prospectus supplement of the registrant relating
to the issuing entity filed on June 29, 2017 pursuant to Rule 424(b)(2))
constitutes a significant obligor within the meaning of Item 1101(k)(2) of
Regulation AB as disclosed in the prospectus supplement. In accordance with
Item 1112(b) of Regulation AB, the most recent unaudited net operating income
of the significant obligor was $20,488,848.06 for the twelve- month period
ended December 31, 2023.

 Item 1114(b)(2) of Regulation AB, Significant Enhancement

enhancement or other support for the certificates within this transaction as
described under Item 1114(a) of Regulation AB.

 Item 1115(b) of Regulation AB, Certain Derivatives

 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.
