Part II - OTHER INFORMATION

Item 2. Legal Proceedings.

Disclosure from Wells Fargo Bank, National Association, as certificate administrator, custodian and/or trustee:

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.
