EXPLANATORY NOTES

The MSBAM 2013-C12 mortgage pool includes the following mortgage loans, each of which is serviced pursuant to a separate pooling and servicing agreement (each, an “Outside Pooling and Servicing Agreement”):

• the Westfield Countryside mortgage loan, which is serviced pursuant to the MSBAM 2013-C11 pooling and servicing agreement attached hereto as Exhibit 4.2.

Except as set forth below, each of the parties to each pooling and servicing agreement listed in the Exhibit Index both (1) participates in the servicing function for purposes of Item 1122 of Regulation AB and (2) constitutes a servicer that meets the criteria in Item 1108(a)(2)(i) through (iii) of Regulation AB for purposes of Item 1123 of Regulation AB:

• The trustee under a pooling and servicing agreement has a nominal role with respect to the mortgage pool securitized pursuant to such pooling and servicing agreement. The trustee’s only servicing function is the contingent obligation to make certain advances if the master servicer under such pooling and servicing agreement fails to do so, while all other servicing functions are performed by other parties. The trustee under each of the pooling and servicing agreements listed in the Exhibit Index has confirmed to the registrant that it has not made any such contingent advances during the reporting period, and consequently, each such trustee does not participate in the servicing function for purposes of Item 1122 of Regulation AB, nor does it perform the functions of a servicer for purposes of the definition of “servicer” under Item 1101 of Regulation AB or for purposes of Item 1123 of Regulation AB.

• The certificate administrator under a pooling and servicing agreement performs various payment administration functions solely for the securitization governed by such pooling and servicing agreement and the mortgage pool securitized pursuant to such pooling and servicing agreement and does not have any obligations with respect to any other transaction. Consequently, the certificate administrator under an Outside Pooling and Servicing Agreement does not participate in the servicing function for purposes of Item 1122 of Regulation AB, nor does it perform the functions of a servicer for purposes of the definition of “servicer” under Item 1101 of Regulation AB or for purposes of Item 1123 of Regulation AB.

• The operating advisor under a pooling and servicing agreement represents the interests of senior certificateholders in the transaction governed by such pooling and servicing agreement and is responsible for monitoring the performance of the special servicer under such pooling and servicing agreement and producing certain reports to certificateholders relating to the resolution of the mortgage pool securitized pursuant to such pooling and servicing agreement. The operating advisor under a pooling and servicing agreement does not have any obligations with respect to any other transaction and is solely obligated to perform loan reporting functions with respect to the securitization governed by such pooling and servicing agreement. Consequently, the operating advisor under an Outside Pooling and Servicing Agreement neither participates in the servicing function for purposes of Item 1122 of Regulation AB nor performs the functions of a servicer for purposes of the definition of “servicer” under Item 1101 of Regulation AB or for purposes of Item 1123 of Regulation AB. In addition, while the operating advisor under a pooling and servicing agreement has certain reporting obligations in respect of the related mortgage pool, it has no obligation to collect or disburse funds in respect of the mortgage pool or to administer any of the underlying mortgage loans. Consequently, the operating advisor under a pooling and servicing agreement participates in the servicing function for purposes of Item 1122 of Regulation AB, but is not responsible for the “management or collection of the pool assets or making allocations or distributions to holders of the asset-backed securities” within the meaning of “servicer” under Item 1101 of Regulation AB and does not perform the functions of a servicer for purposes of Item 1123 of Regulation AB.

• Rialto Capital Advisors, LLC is the current special servicer under the MSBAM 2013-C12 pooling and servicing agreement. On June 24, 2021, Midland Loan Services, a Division of PNC Bank, National Association was replaced as special servicer under the MSBAM 2013-C12 pooling and servicing agreement and was succeeded by CWCapital Asset Management LLC. On April 29, 2025, CWCapital Asset Management LLC was replaced as special servicer under the MSBAM 2013-C12 pooling and servicing agreement and was succeeded by Rialto Capital Advisors, LLC.

• BellOak, LLC is the current operating advisor under the MSBAM 2013-C12 pooling and servicing agreement. On March 31, 2023, Trimont Real Estate Advisors, LLC resigned as operating advisor under the MSBAM 2013-C12 pooling and servicing agreement and was succeeded by BellOak, LLC.

• Effective as of March 1, 2025, Trimont LLC purchased the third party servicing segment of Wells Fargo Bank, National Association’s commercial mortgage servicing business and replaced Wells Fargo Bank, National Association in its capacities as master servicer, primary servicer and special servicer, as applicable, under the MSBAM 2013-C12 pooling and servicing agreement and each Outside Pooling and Servicing Agreement.

In addition, each of the following parties engaged the services of certain servicing function participants and sub-servicers for the reporting period, as set forth below:

• Wells Fargo Bank, National Association, as master servicer, engaged the services of CoreLogic Solutions, LLC as a servicing function participant in respect of the entire mortgage pool for the reporting period.

• Wells Fargo Bank, National Association, as master servicer under the MSBAM 2013-C11 pooling and servicing agreement, pursuant to which the Westfield Countryside mortgage loan is serviced, engaged the services of CoreLogic Solutions, LLC as a servicing function participant in respect of the Westfield Countryside mortgage loan for the reporting period.

• On November 1, 2021, pursuant to the second amended and restated servicing agreement attached hereto as Exhibit 99.4, Computershare Trust Company, National Association was engaged to perform all or virtually all of Wells Fargo Bank, National Association’s roles as certificate administrator, custodian and trustee, as applicable, under (i) the pooling and servicing agreement and (ii) each Outside Pooling and Servicing Agreement.

• Effective as of March 1, 2025, Trimont LLC, as the successor to Wells Fargo Bank, National Association in each of its servicing capacities described above, engaged CoreLogic Solutions, LLC to act as a servicing function participant with respect to the same servicing and reporting functions for which Wells Fargo Bank, National Association engaged CoreLogic Solutions, LLC as described above.

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.

U.S. Bank National Association (“U.S. Bank”) and other large financial institutions have been sued in their capacity as trustee or successor trustee for certain residential mortgage backed securities ("RMBS") trusts. The complaints, primarily filed by investors or investor groups against U.S. Bank and similar institutions, allege the trustees caused losses to investors as a result of alleged failures by the sponsors, mortgage loan sellers and servicers to comply with the governing agreements for these RMBS trusts. Plaintiffs generally assert causes of action based upon the trustees’ purported failures to enforce repurchase obligations of mortgage loan sellers for alleged breaches of representations and warranties, notify securityholders of purported events of default allegedly caused by breaches of servicing standards by mortgage loan servicers and abide by a heightened standard of care following alleged events of default.

U.S. Bank denies liability and believes that it has performed its obligations under the RMBS trusts in good faith, that its actions were not the cause of losses to investors, that it has meritorious defenses, and it has contested and intends to continue contesting the plaintiffs’ claims vigorously. However, U.S. Bank cannot assure you as to the outcome of any of the litigation, or the possible impact of these litigations on the trustee or the RMBS trusts.

On March 9, 2018, a law firm purporting to represent fifteen Delaware statutory trusts (the “DSTs”) that issued securities backed by student loans (the “Student Loans”) filed a lawsuit in the Delaware Court of Chancery against U.S. Bank National Association (“U.S. Bank”) in its capacities as indenture trustee and successor special servicer, and three other institutions in their respective transaction capacities, with respect to the DSTs and the Student Loans. This lawsuit is captioned The National Collegiate Student Loan Master Trust I, et al. v. U.S. Bank National Association, et al., C.A. No. 2018-0167-JRS (Del. Ch.) (the “NCMSLT Action”). The complaint, as amended on June 15, 2018, alleged that the DSTs have been harmed as a result of purported misconduct or omissions by the defendants concerning administration of the trusts and special servicing of the Student Loans. Since the filing of the NCMSLT Action, certain Student Loan borrowers have made assertions against U.S. Bank concerning special servicing that appear to be based on certain allegations made on behalf of the DSTs in the NCMSLT Action.

U.S. Bank has filed a motion seeking dismissal of the operative complaint in its entirety with prejudice pursuant to Chancery Court Rules 12(b)(1) and 12(b)(6) or, in the alternative, a stay of the case while other prior filed disputes involving the DSTs and the Student Loans are litigated. On November 7, 2018, the Court ruled that the case should be stayed in its entirety pending resolution of the first-filed cases. On January 21, 2020, the Court entered an order consolidating for pretrial purposes the NCMSLT Action and three other lawsuits pending in the Delaware Court of Chancery concerning the DSTs and the Student Loans, which remains pending.

U.S. Bank denies liability in the NCMSLT Action and believes it has performed its obligations as indenture trustee and special servicer in good faith and in compliance in all material respects with the terms of the agreements governing the DSTs and that it has meritorious defenses. It has contested and intends to continue contesting the plaintiffs’ claims vigorously.

From time to time, CWCapital Asset Management LLC, a Delaware limited liability company (“CWCAM”), is a party to lawsuits and other legal proceedings as part of its duties as a special servicer (e.g., enforcement of loan obligations) and/or arising in the ordinary course of business. Other than as set forth in the following paragraphs, there are currently no legal proceedings pending, and no legal proceedings known to be contemplated by governmental authorities, against CWCAM or of which any of its property is the subject, that are material to the certificateholders.

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 gravamen of the Original Complaint alleged breaches of a contract and fiduciary duties by CWCAM’s affiliate, CWCapital Investments LLC 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 judgement 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 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 the 16 counts and partially dismissing 2 additional counts. Of the remaining counts, 2 are asserted against CWCAM for aiding and abetting 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 (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-appealable on August 30, 2022. Discovery (both fact and expert) concluded on March 1, 2024. CWCAM and CWCI filed a motion for summary judgment on March 29, 2024, seeking dismissal of all the claims 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 (“Bridge Investment Group or “Bridge”), as Directing Certificateholder (“DCH”) filed suit against CWCapital Asset Management LLC (“CWCAM”), alleging breach of the subject Pooling and Servicing Agreement (“PSA”) and violation of the Servicing Standard 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 (the “Ranger Portfolio”) 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 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.
