EXPLANATORY NOTES

The Exhibit Index describes exhibits provided by certain parties (in their capacities indicated on the Exhibit Index) with respect to the La Gran Plaza Mortgage Loan, which constituted approximately 1.8% of the asset pool of the issuing entity as of its cut-off date. The La Gran Plaza Mortgage Loan is an asset of the issuing entity and is part of a loan combination that includes the La Gran Plaza 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-CCRE24 Mortgage Trust transaction, Commission File Number 333-193376-21 (the “COMM 2015-CCRE24 Transaction”). This loan combination, including the La Gran Plaza Mortgage Loan, is being serviced and administered pursuant to the pooling and servicing agreement for the COMM 2015-CCRE24 Transaction, which is incorporated by reference as Exhibit 4.2 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.

Park Bridge Lender Services LLC is the operating advisor of the mortgage loans serviced under the Pooling and Servicing Agreement and the La Gran Plaza Mortgage Loan. As a result, Park Bridge Lender Services LLC is a servicing function participant in the capacities described above, because it is servicing mortgage loans that constituted 5% or more of the assets of the issuing entity as of its cut-off date. The assessments of compliance with applicable servicing criteria and accountants’ attestation reports delivered by Park Bridge Lender Services LLC 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 and the La Gran Plaza Mortgage Loan. Pursuant to the Pooling and Servicing Agreement and the pooling and servicing agreement for the COMM 2015-CCRE24 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 and the La Gran Plaza Mortgage Loan have delivered one or more assessments of compliance with respect to Item 1122(d)(2)(iii) of Regulation AB.

The assessment of compliance with applicable servicing criteria, accountants’ attestation report and servicer compliance statement of the certificate administrator of the La Gran Plaza Mortgage Loan is 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 it is 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 La Gran Plaza Mortgage Loan, (i) the reports on assessment of compliance with servicing criteria and attestation reports on assessment of compliance with servicing criteria of Wells Fargo Bank, National Association as primary servicer prior to March 1, 2025 and custodian of the La Gran Plaza Mortgage Loan, Trimont LLC as primary servicer of the La Gran Plaza Mortgage Loan on and after March 1, 2025 and LNR Partners, LLC as special servicer of the La Gran Plaza 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 Wells Fargo Bank, National Association as primary servicer of the La Gran Plaza Mortgage Loan prior to March 1, 2025, Trimont LLC as primary servicer of the La Gran Plaza Mortgage Loan on and after March 1, 2025 and LNR Partners, LLC as special servicer of the La Gran Plaza 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.

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 Deutsche Bank Trust Company Americas, as certificate administrator and custodian~~, and Wells Fargo Bank, National Association, as certificate administrator and custodian~~.

In 2014 and 2015, several investors sued several trustees of residential mortgage-backed securities (“RMBS”) trusts, including Deutsche Bank Trust Company Americas (“DBTCA”), concerning the trustees’ administration of RMBS trusts. These cases generally alleged that the RMBS trustees failed to perform purported duties, as trustees for 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. Investors have sued DBTCA in six of these cases. DBTCA has settled two cases brought by funds managed by Blackrock Advisors, LLC, PIMCO-Advisors, L.P. and others; and obtained summary judgment in one case, brought by certain special purpose entities including Phoenix Light SF Limited. In addition, the two cases described below remain active.

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 Deutsche Bank National Trust Company (“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 U.S. Trust Indenture Act of 1939 (“TIA”); breach of contract; breach of fiduciary duty; negligence; violation of the New York Streit Act (“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. On September 26, 2024, DBNTC and DBTCA filed a motion for summary judgment, which has been fully briefed.

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~~ trustees defending lawsuits by IKB, filed a joint motion to dismiss. On January 6, 2017, IKB filed a notice of discontinuance, voluntarily ~~dismissing~~ dismissing with prejudice all claims as to three trusts. On June 20, 2017, the parties filed a stipulation, voluntarily dismissing with ~~prejudice~~ prejudice all claims as to four additional trusts. On January 27, 2021, the court granted in part and denied in part DBNTC and DBTCA’s ~~motion~~ 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. On November 14, 2024, DBNTC and DBTCA filed a motion for summary judgment. Also on November 14, 2024, IKB filed a motion for partial summary judgment. ~~Those~~On August 11, 2025, the court granted in part and denied in part certain aspects of both motions. ~~are~~On ~~being~~October ~~briefed~~20, 2025, the court resolved the remainder of both motions and dismissed certain additional claims. All parties have filed notices of appeal with respect to certain aspects of the court’s summary judgment orders.

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

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.
