OnItem ~~June 18, 2014, a group of investors, including funds managed by Blackrock Advisors, LLC, PIMCO-Advisors, L~~9.~~P.,~~ ~~and~~Other others, filed an action against DBNTC and DBTCA in New York State Supreme Court alleging that DBNTC and DBTCA failed to perform purported duties, as trustees for 544 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 trustsInformation. ~~During~~ the course of the litigation, plaintiffs dismissed the case from New York State Supreme Court and refiled two separate cases, one in the U.S. District Court for the Southern District of New York (the “BlackRock SDNY Case”) and the other in the Superior Court of California, Orange County (the “BlackRock California Case”). Pursuant to a settlement among the parties, the BlackRock SDNY Case was dismissed on December 6, 2018, and the BlackRock California Case was dismissed on January 11, 2019.

OnWells ~~September~~Fargo 27Bank, ~~2017, DBTCA was added as a defendant to a case brought by certain special purpose entities including Phoenix Light SF Limited in the U~~N.SA. ~~District Court for the Southern District of New York~~, in ~~which the plaintiffs~~its ~~previously~~capacity ~~alleged incorrectly that DBNTC served~~ as ~~trustee~~Master ~~for~~Servicer ~~all 43 of the trusts at issue. On September 27, 2017, plaintiffs filed a third amended complaint that names DBTCA as a defendant in addition to DBNTC. DBTCA serves as trustee~~ for ~~one~~Morgan ofStanley ~~the~~Bank ~~43 trusts at issue. DBNTC serves as trustee for the other 42 trusts at issue. Plaintiffs’ third amended complaint brings claims for violation~~ of ~~the~~America ~~U.S.~~Merrill Lynch Trust Indenture Act of 1939 (“TIA”); breach of contract; breach of fiduciary duty; negligence and gross negligence; violation of the New York Streit Act (“Streit Act”); and breach of the covenant of good faith. However2014-C15, inaffirms the ~~third~~ ~~amended~~following ~~complaint,~~amounts plaintiffs acknowledge that, before DBTCA was added to the case, the court dismissed plaintiffs’ TIA claims, negligence and gross negligence claims, Streit Act claims, claims for breach of the covenant of good faith, and certain theories of plaintiffs’ breach of contract claims, and plaintiffs only include these claims to preserve any rights on appeal. Plaintiffs allege damages of “hundreds of millions of dollars.” On November 13, 2017, DBNTC and DBTCA filed an answer to the third amended complaint. On December 7, 2018, DBNTC and DBTCA filed a motion for summary judgment. Also on December 7, 2018, plaintiffs, jointly with Commerzbank AG (see description of Commerzbank case below), filed a motion for partial summary judgment. On October 27, 2021, DBNTC and DBTCA filed a supplemental motion for summary judgment relating to plaintiffs’ standing. On February 8, 2022, the court issued an order in which it granted DBNTC and DBTCA’s supplemental motion for summary judgment, granted in part DBNTC and DBTCA’s initial motion for summary judgment, and denied plaintiffs’ motion for partial summary judgment. As a result of that order, all of plaintiffs’ claims were dismissed with prejudice. On April 26, 2023, the ~~United~~respective ~~States Court of Appeals for the Second Circuit affirmed the court’s summary judgment order.~~ accounts:

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 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 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, 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. Discovery is ongoing.

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. Discovery is ongoing.
