In the ordinary course of business, The Bank of New York Mellon, The Bank of New York Mellon Trust Company, N.A., and BNY Mellon Trust of Delaware (collectively, “BNY Mellon”) are named as a defendant in legal actions. In connection with its role as trustee of certain residential mortgage-backed securitizations, or RMBS transactions, BNY Mellon has been named as a defendant in a number of legal actions brought by RMBS investors. These lawsuits allege that the trustee had expansive duties under the governing agreements, including the duty to investigate and pursue breach of representation and warranty claims against other parties to the RMBS transactions.

According to Schedule B of Exhibit 33.2 of this Form 10-K, the Indenture Trustee has enhanced controls aimed at preventing missed payments.
