Part II - OTHER INFORMATION

Item 2. Legal Proceedings.

Disclosure from Deutsche Bank National Trust Company, as Trustee:

In 2014 and 2015, several investors sued several trustees of residential mortgage-backed securities (“RMBS”) trusts, including Deutsche Bank National Trust Company (“DBNTC”), 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 DBNTC in nine of these cases. DBNTC has settled two cases brought by funds managed by Blackrock Advisors, LLC, PIMCO-Advisors, L.P. and others; settled two cases brought by Royal Park Investments SA/NV; settled one case brought by IKB International, S.A. in Liquidation and IKB Deutsche Industriebank A.G.; obtained summary judgment in one case, brought by certain special purpose entities including Phoenix Light SF Limited; and obtained a dismissal in one case, brought by the Western and Southern Life Insurance Company and five related entities. In addition, the two cases described below remain active.

On November 7, 2014, the National Credit Union Administration Board (“NCUA”), as an investor in 121 RMBS trusts, filed a complaint in the U.S. District Court for the Southern District of New York against DBNTC as trustee of those trusts, alleging violations of the U.S. Trust Indenture Act of 1939 (“TIA”) and the New York Streit Act (“Streit Act”) for DBNTC’s alleged failure to perform certain purported statutory and contractual duties. On March 5, 2015, NCUA amended its complaint to assert claims as an investor in 97 of the 121 RMBS trusts that were the subject of its first complaint. The amended complaint alleged violations of the TIA and Streit Act, as well as breach of contract, breach of fiduciary duty, breach of the covenant of good faith, negligence, gross negligence and negligent misrepresentation. NCUA’s complaint alleged that the trusts at issue suffered total realized collateral losses of U.S. $17.2 billion, but the complaint did not include a demand for money damages in a sum certain. On May 1, 2015, DBNTC filed a motion to dismiss the amended complaint. On July 31, 2018, the court issued an order that, among other things, denied DBNTC’s motion to dismiss without prejudice to its renewal. On August 31, 2018, NCUA filed a letter informing the court that it intended to: (i) drop all of its claims as to 60 of the 97 trusts at issue; (ii) drop its claims as to certain, but not all, certificates for 3 additional trusts; and (iii) move for leave to file an amended complaint bringing claims as to the remaining 37 trusts at issue. On October 5, 2018, NCUA filed a motion for leave to file a second amended complaint that asserted claims as to only 37 of the 97 trusts that were originally at issue, and added new claims for a declaratory judgment and breach of contract arising out of the payment from trust funds of DBNTC’s legal fees and expenses in NCUA’s action and in other actions brought by investors against DBNTC for alleged breaches of its duties as an RMBS trustee. On November 5, 2018, DBNTC filed a motion to stay NCUA’s new claims relating to payment from trust funds of DBNTC’s legal fees and expenses and all related discovery. On October 15, 2019, the court: (i) granted in part NCUA’s motion for leave to file a second amended complaint; and (ii) granted DBNTC’s motion to stay NCUA’s new claims relating to payment from trust funds of DBNTC’s legal fees and expenses and all related discovery. The court permitted NCUA to file a second amended complaint asserting claims for: (i) breach of contract arising out of DBNTC’s alleged failure to perform certain purported statutory and contractual duties; and (ii) declaratory judgment and breach of contract arising out of the payment from trust funds of DBNTC’s legal fees and expenses. The court denied NCUA’s request to assert additional claims for: (i) negligence and gross negligence; and (ii) breach of fiduciary duty. On October 21, 2019, NCUA filed a second amended complaint. On November 15, 2019, DBNTC filed an answer to the second amended complaint. On June 11, 2021, NCUA filed a third amended complaint, the substance of which was unchanged from the second amended complaint. On July 1, 2021, DBNTC filed an answer to the third amended complaint. On October 5, 2021, NCUA filed a fourth amended complaint, the substance of which was unchanged from the third amended complaint. On October 25, 2021, DBNTC filed an answer to the fourth amended complaint. On February 4, 2022, the parties filed a stipulation in which NCUA agreed to voluntarily dismiss with prejudice all claims as to 19 trusts. On February 28, 2022, both parties filed motions for partial summary judgment. On August 15, 2025, the court granted in part and denied in part both motions, and on October 9, 2025, the court entered the parties’ stipulation dismissing certain additional claims based on the summary judgment decision. Discovery is ongoing.

On December 23, 2015, Commerzbank AG (“Commerzbank”), as an investor in 50 RMBS trusts, filed a complaint in the U.S. District Court for the Southern District of New York against DBNTC as trustee of the trusts, asserting claims for violations of the TIA and New York’s Streit Act, breach of contract, breach of fiduciary duty, negligence, and breach of the covenant of good faith, based on DBNTC’s alleged failure to perform its duties as trustee for the trusts. Commerzbank alleges that DBNTC caused it 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 April 29, 2016, Commerzbank filed an amended complaint. The amended complaint asserts the same claims as did the original complaint, and, like the original complaint, alleges that DBNTC caused Commerzbank to suffer “hundreds of millions of dollars in losses,” but does not include a demand for money damages in a sum certain. On May 27, 2016, DBNTC filed a motion to dismiss the amended complaint. On February 10, 2017, the court granted in part and denied in part DBNTC’s motion to dismiss. The court granted the motion to dismiss with respect to Commerzbank’s claim for breach of the covenant of good faith and claim under the Streit Act, dismissing those claims with prejudice. The court also granted the motion to dismiss with respect to Commerzbank’s claim under the TIA as to the 46 trusts at issue governed by pooling and servicing agreements, dismissing that claim with prejudice as to those 46 trusts. The court also granted the motion to dismiss, without prejudice, with respect to Commerzbank’s breach of contract claim as to ten trusts whose governing agreements limit the right to file suit under the governing agreements to certain specified parties, including the registered holder of a certificate issued by the trust. The court held that, although Commerzbank has not received authorization from the registered holder of the certificates at issue to file suit, it may still obtain that authorization from the registered holder. The court denied the remainder of the motion to dismiss. Therefore, with the exception of the claims relating to the ten trusts for which Commerzbank has not received authorization to file suit, Commerzbank’s claims for breach of contract, breach of fiduciary duty, and negligence will proceed. Commerzbank’s claim under the TIA as to the four trusts governed by agreements other than pooling and servicing agreements will also proceed. On May 1, 2017, DBNTC filed an answer to the amended complaint. On November 30, 2017, Commerzbank filed a second amended complaint that names Deutsche Bank Trust Company Americas (“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 TIA; breach of contract; breach of fiduciary duty; negligence; violation of the Streit Act; and breach of the covenant of good faith. However, in the second amended complaint, Commerzbank acknowledges that the court previously dismissed its 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.

It is DBNTC’s belief that it has no pending legal proceedings (including, based on DBNTC’s current evaluation, the litigation disclosed in the foregoing above) that would materially affect its ability to perform its duties under the Pooling and Servicing Agreement for this transaction.
