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.

Trimont LLC is the master servicer of the mortgage loans serviced under the Pooling and Servicing Agreement on and after March 1, 2025 and the primary servicer of the CityPlace I Mortgage Loan and the Yosemite Resorts Mortgage Loan on and after March 1, 2025. As a result, Trimont LLC 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.

These servicing functions are included within the servicing criteria set forth in Item 1122(d)(4)(xi) 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”).

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 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 October 2024, the Second Circuit denied Commerzbank AG’s appeal. 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.
