On December 1, 2017, a complaint against CWCAM and others was filed in the United States District Court for the Southern District of New York styled as CWCapital Cobalt Vr Ltd. v. CWCapital Investments LLC, et al., No. 17-cv-9463 (the “Original Complaint”). The ~~following~~gravamen ~~table~~of ~~sets~~the ~~forth~~Original Complaint ~~information~~alleged ~~about~~breaches of a contract and fiduciary duties by CWCAM’s ~~Trimont~~affiliate, CWCapital Investments LLC (“CWCI”) in its capacity as collateral manager for the collateralized debt obligation transaction involving CWCapital Cobalt Vr, Ltd. In total, there are 14 counts pled in the Original Complaint. Of those 14, 5 claims were asserted against CWCAM for aiding and abetting breach of fiduciary duty, conversion and unjust enrichment. On May 23, 2018, the Original Complaint was dismissed for lack of subject matter jurisdiction. On June 28, 2018, CWCapital Cobalt Vr Ltd. filed a substantially similar complaint in the Supreme Court of the State of New York, County of New York styled as CWCapital Cobalt Vr Ltd. v. CWCapital Investments LLC, et al., Index No. 653277/2018 (the “New Complaint”). The gravamen of the New Complaint is the same as the previous complaint filed in the United State District Court for the Southern District of New York. In total there are 16 counts pled in the New Complaint. Of those 16 counts, 5 claims were asserted against CWCAM for aiding and abetting breach of fiduciary duty, conversion and unjust enrichment, 1 count seeks a declaratory judgment that the plaintiff has the right to enforce the contracts in question and 1 count seeks an injunction requiring the defendants to recognize the plaintiff as the directing holder for the trusts in question. On January 11, 2019, the plaintiff dismissed with prejudice the declaratory judgment and injunction counts. The New Complaint and related summons was not served on the defendants until July 13, 2018 and July 16, 2018. The plaintiff’s ~~portfolio~~motion for a preliminary injunction was denied by the court on July 31, 2018. On August 3, 2018, the defendants, including CWCAM, filed a motion to dismiss the New Complaint in its entirety. On August 20, 2019, the court entered an order granting defendants’ motion almost in its entirety, dismissing 11 of ~~master~~the or16 ~~primary~~counts ~~serviced~~and ~~commercial~~partially dismissing 2 additional counts. Of the remaining counts, 2 are asserted against CWCAM for aiding and ~~multifamily~~abetting ~~loans~~breach of fiduciary duty and unjust enrichment. On September 19, 2019, CWCapital Cobalt Vr Ltd. filed a notice of appeal relating to the August 20, 2019 dismissal order and on September 26, 2019, filed an amended complaint against CWCI and CWCAM attempting to address deficiencies relating to certain of the claims dismissed by the August 20, 2019 order. CWCI and CWCAM filed its Motion to Dismiss the amended complaint on October 28, 2019. The court heard argument on the Motion to Dismiss the amended complaint on January 22, 2020 and on October 23, 2020, the court granted the motion dismissing the amended claims. On November 30, 2020, CWCapital Cobalt Vr Ltd filed a notice of appeal relating to the October 23, 2020 dismissal order. On April 27, 2021, the First Department affirmed the dismissal as to claims against CWCAM that were part of the August 20, 2019 dismissal, but reversed the dismissal of two counts for breach of the collateral management agreement against CWCI. CWCI sought leave to file an appeal of the decision. The plaintiff also sought leave to appeal the dismissal of the claims against CWCAM. Both requests for leave were denied by the First Department. On May 15, 2020, CWCI and CWCAM filed a motion to renew its motion to dismiss as to 4 of the remaining counts (~~securitized~~including the remaining two counts against CWCAM for aiding and abetting breach of fiduciary duty and unjust enrichment), based on a decision entered by Judge Failla in a trust instruction proceeding in the US District Court for the Southern District of New York awarding summary judgment in favor of CWCAM. On September 7, 2021, the court denied the motion to renew. CWCI and CWCAM filed a notice of appeal, which they perfected by the filing of their opening brief on July 1, 2022. On November 15, 2022, the First Department affirmed the court’s denial of the motion to renew. On October 1, 2021, CWCI and CWCAM moved to reargue the denial of the motion to renew (or alternatively, the motion to dismiss) with respect to certain of Cobalt’s claims, including the remaining 2 claims against CWCAM, based on the First Department’s April 27, 2021 decision. On March 24, 2022, the court denied the relief sought in the motion to reargue. CWCI and CWCAM appealed the court’s decision on the motion to reargue and filed their opening brief on July 11, 2022. The appeal was dismissed as being non-~~securitized~~appealable on August 30, 2022. Discovery (both fact and expert) asconcluded on March 1, 2024. CWCAM and CWCI filed a motion for summary judgment on March 29, 2024, seeking dismissal of all the ~~dates~~claims ~~indicated~~in their entirety. On that same date, the plaintiff cross moved for summary judgment on one of the claims asserted against only CWCI. Oral argument on the parties’ summary judgment motions were heard on October 22, 2024. On January 13, 2026, the court denied plaintiff’s motion for summary judgment and granted, in part, and denied, in part, the motion filed by CWCI and CWCAM. Specifically, the court dismissed the remaining two counts against CWCAM for aiding and abetting breach of fiduciary duty and unjust enrichment. With respect to CWCI, the court dismissed two counts against CWCI in their entirety and dismissed portions of one count against CWCI. The only three counts that survived and remain in the case are against CWCI. The court severed the dismissed claims from the surviving claims. On January 22, 2026, CWCI and CWCAM submitted an order to the court, requesting that it direct the clerk’s office to enter judgment on the dismissed claims and that CWCAM be dismissed as a defendant from the action. CWCAM believes that it has performed its obligations under the related pooling and servicing agreements in good faith.

On January 13, 2025, in the Supreme Court of the State of New York, ROC Debt Strategies II Bond Investments LLC, as directing certificateholder filed suit against CWCAM, alleging breach of the FREMF 2016-KS06 pooling and servicing agreement (“FREMF 2016-KS06 PSA”) and violation of the servicing standard under the FREMF 2016-KS06 PSA while acting as special servicer for the FREMF 2016-KS06 pool. It is alleged that CWCAM was negligent in the servicing of a portfolio of 9 loans that were in special servicing starting in 2022. The suit demands unspecified compensatory damages and a declaratory judgment that CWCAM is not entitled to indemnification or payment for expenses from the trust under the FREMF 2016-KS06 PSA. CWCAM disagrees vehemently with these allegations and a motion to dismiss was filed by CWCAM on March 14, 2025. The motion has been fully briefed and a hearing was held on August 25, 2025. While that motion was pending, the parties reached a business resolution and by stipulation the lawsuit was dismissed with prejudice on January 22, 2026.

Trimont has operating procedures across the various servicing functions to maintain compliance with its servicing obligations and servicing standards under Trimont’s servicing agreements. The only significant changes in Trimont’s policies and procedures over the past three years have come in response to changes in federal or state law or investor requirements. Trimont expects to incorporate CMS policies and procedures into its best practices for servicing CMS Loans and newly originated commercial and multifamily loans.

Trimont’s servicing platform allows Trimont to process loan servicing activities including, but not limited to: (i) performing account maintenance; (ii) tracking borrower communications; (iii) tracking real estate tax escrows and payments, insurance escrows and payments, replacement reserve escrows and operating statement data and rent rolls; (iv) entering and updating transaction data; and (v) generating various reports.

Prior to the CMS Acquisition Closing Date, Trimont was not the designated primary advancing agent for any of the loans it serviced. In connection with the CMS Transaction, Trimont acquired the outstanding CMS servicer advances using funding from a Wells Fargo credit facility and other capital sources and assumed the future advancing obligations of Wells Fargo under the servicing agreements that transferred to Trimont.

The following table sets forth pro forma information regarding principal and interest advances and protective property advances held by Trimont, as master servicer, on commercial and multifamily mortgage loans included in commercial mortgage-backed securitizations. The information set forth below is the pro forma amount of such advances outstanding as of the date indicated (expressed as a dollar amount and as a percentage of the Trimont pro forma portfolio, as of the end of such period, of master serviced commercial and multifamily mortgage loans included in commercial mortgage-backed securitizations).

*Represents pro forma portfolio and includes CMS Loans (as hereinafter defined).

** “UPB” means unpaid principal balance, “P&I” means principal and interest advances and “PPA” means property protection advances.

Trimont may perform some of its obligations under the applicable servicing agreement through one or more third-party vendors, affiliates or subsidiaries, including the engagement of third-party vendors to provide technology or process efficiencies. Trimont monitors its third-party vendors in compliance with its internal procedures and applicable law. Trimont has entered into contracts directly with third-party vendors and may also obtain services from third party vendors through Wells Fargo under the TSA (as hereinafter defined) for some or all of the following functions:

· provision of Strategy and Strategy CS software;

· audit services;

· tracking and reporting of flood zone changes;

· abstracting of leasing consent requirements contained in loan documents;

· legal representation;

· assembly of data regarding buyer and seller (borrower) with respect to proposed loan assumptions and preparation and underwriting of loan assumption package for review by servicer;

· performance of property inspections;

· performance of tax parcel searches based on property legal description, monitoring and reporting of delinquent taxes, and collection and payment of taxes;

· Uniform Commercial Code searches and filings;

· insurance tracking and compliance;

· onboarding-new loan setup;

· lien release-filing & tracking;

· credit investigation & background checks; and

· defeasance calculations.

Trimont may also enter into agreements with certain firms to act as a primary servicer (or sub-servicer) and to provide cashiering or non-cashiering subservicing on the mortgage loans. Trimont will monitor and review the performance of sub-servicers appointed by it. Generally, all amounts received by Trimont on the mortgage loans will initially be deposited into a common clearing account with collections on other mortgage loans serviced by Trimont and will then be allocated and transferred to the appropriate account as described in the related prospectus. On the day any amount is to be disbursed by Trimont, that amount may be transferred to a common disbursement account prior to disbursement.

Trimont will not have primary responsibility for custody services of original documents evidencing the mortgage loans. On occasion, Trimont may have custody of certain of such documents as are necessary for enforcement actions involving the mortgage loans or otherwise. To the extent Trimont performs custodial functions as a servicer, documents will be maintained in a manner consistent with the servicing standard.

There are, to the actual current knowledge of Trimont, no special or unique factors of a material nature involved in servicing the mortgage loans, as compared to the types of assets serviced by Trimont in other commercial real estate securitization pools generally.

Trimont does not believe that its financial condition will have any adverse effect on the performance of its duties under the applicable servicing agreement and, accordingly, Trimont believes that its financial condition will not have any material impact on the performance of the mortgage loans or the certificates.

No securitization involving commercial or multifamily real estate loans in which Trimont was acting as a servicer has experienced a servicer event of default as a result of any action or inaction of Trimont in such capacity, including as a result of Trimont’s failure to comply with the applicable servicing criteria in connection with any securitization.

From time to time, Trimont is a party to lawsuits and other legal proceedings as part of its duties as a loan servicer (e.g., enforcement of loan obligations) and/or arising in the ordinary course of business. Trimont does not believe that any such lawsuits or legal proceedings, individually or in the aggregate, would be material to the certificateholders. There are no legal proceedings pending against Trimont, or to which any property of Trimont is subject, that are material to the certificateholders, nor does Trimont have actual knowledge of any proceedings of this type contemplated by governmental authorities.

A Trimont website (https://cmsview.trimont.com) provides investors with access to investor reports for commercial mortgage-backed securitization transactions for which Trimont is master servicer, and also provides borrowers with access to current and historical loan and property information for these transactions.

The following table sets forth information as of the dates indicated about Trimont’s servicing portfolio of specially serviced commercial and multifamily loans (securitized and non-securitized):

Commercial and Multifamily Mortgage Loans	As of 12/31/2022	As of 12/31/2023	As of 12/31/2024	As of 12/31/2024 (pro forma) **

By Approximate Aggregate Unpaid Principal Balance (in billions):	$0.6	$2.1	$3.4	$79.9

** Represents pro forma portfolio and includes CMS Loans (as hereinafter defined).

The properties securing the loans in Trimont’s special servicing portfolio (including CMS Loans (as hereinafter defined)) include multifamily, office, retail, hospitality, industrial and other income producing properties.

Within this special servicing portfolio (including CMS Loans), as of December 31, 2024, approximately 2,321 commercial and multifamily loans with an unpaid principal balance of approximately $77.1 billion are loans that back commercial mortgage-backed securities or commercial real estate collateralized debt obligation securities.

Generally, Trimont’s servicing functions under servicing agreements as special servicer do not include maintenance of collection accounts, however Trimont does maintain certain operating accounts with respect to REO loans in accordance with the terms of the applicable servicing agreements and consistent with the servicing standard set forth in each of such servicing agreements.

Trimont does not generally have any material advancing rights or obligations with respect to the commercial real estate securitization pools as to which it acts as special servicer. In certain instances, Trimont may have the right or be obligated to make property related servicing advances in emergency situations with respect to certain commercial real estate securitization pools as to which it acts as special servicer.

Trimont has developed strategies and procedures for managing delinquent loans, breaches by borrowers of the underlying loan documents and loans subject to borrower bankruptcy filings which are designed to maximize value from the assets for the benefit of certificateholders. These strategies and procedures vary on a case by case basis and include but are not limited to, liquidation of the underlying collateral, note sales, discounted payoffs and borrower negotiation or workout in accordance with the applicable servicing standard. The strategy pursued by Trimont for any particular asset depends upon, among other things, the condition and type of the underlying property, the borrower, and the jurisdiction where the asset is located.

Trimont, as special servicer, may enter into one or more arrangements with the controlling class representative, directing certificateholder, or equivalent party or related entity, which has the right to remove, or vote to remove the special servicer, to provide for a discount and/or revenue sharing with respect to certain special servicer compensation. The controlling class representative, directing certificateholder, or equivalent party or related entity, which has the right to remove, or vote to remove the special servicer, may further consider any such economic arrangements with the special servicer or a prospective replacement servicer in entering into any decision to appoint or replace the special servicer from time to time, and such considerations would not be required to take into account the best interests of any certificateholder.

CMS Transaction. As of the CMS Acquisition Closing Date, Trimont purchased the third party servicing segment (“CMS”) of Wells Fargo Bank, National Association’s (“Wells Fargo”) commercial mortgage servicing business. The CMS Transaction did not include Wells Fargo’s rights and obligations related to the servicing of loans that Wells Fargo originated for Fannie Mae, Freddie Mac, and FHA/Ginnie Mae, which will continue to be serviced by Wells Fargo.

Senior leadership of Trimont and CMS and certain Trimont and former Wells Fargo corporate functions that supported CMS are expected to be generally integrated within Trimont on or shortly following the CMS Acquisition Closing Date. Most of the CMS employees along with relevant CMS systems, technologies and operating procedures and guidelines supporting CMS were transferred to Trimont as part of the CMS Transaction. Further, as of the CMS Acquisition Closing Date, Wells Fargo’s duties, obligations, and rights as servicer, under the related servicing agreements were transferred to Trimont, subject to the terms and conditions of such servicing agreements.

In order to facilitate the transition of CMS to Trimont, Wells Fargo and Trimont entered into a Transition Services Agreement (“TSA”) pursuant to which Wells Fargo agreed to provide certain support services, or cause such services to be provided, to Trimont for 12 months from the CMS Acquisition Closing Date (with two 3-month extension options) (the “TSA Period”).

Following the CMS Acquisition Closing Date, Trimont will initially be operating two loan servicing technology platforms with each using a separate instance of McCracken Financial Solutions software, Strategy CS. During a portion or all of the TSA Period, Trimont expects to continue to service the loans it was servicing prior to the CMS Acquisition Closing Date (“Pre-Closing Trimont Loans”) using operating guidelines, procedures and the servicing technology platform that Trimont was using prior to the CMS Acquisition Closing Date. During a portion or all of the TSA Period, Trimont expects to service loans serviced under the servicing agreements transferred in connection with the CMS Transaction and loans serviced under CMBS servicing agreements entered into by Trimont after the CMS Acquisition Closing Date (“CMS Loans”) in accordance with the CMS operating guidelines, procedures and servicing technology platform.
