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.

LNR Partners, LLC is the special servicer of the Park Square Mortgage Loan and the U.S. Industrial Portfolio III Mortgage Loan.

Therefore, the Depositor included in this Annual Report on Form 10-K an assessment of compliance with applicable servicing criteria for LNR Partners, LLC and an accountants’ attestation report pursuant to Item 1122 of Regulation AB because LNR Partners, LLC is servicing more than 5% of the pool assets. However, the Depositor is not required to include in this Annual Report on Form 10-K a servicer compliance statement pursuant to Item 1123 of Regulation AB of LNR Partners, LLC because LNR Partners, LLC is an unaffiliated servicer servicing less than 10% of pool assets.

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”). 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.

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.
