The Bank of New York Mellon (formerly The Bank of New York) (BNYM and as US$ note
trustee, US$ note registrar and principal paying agent) has provided the following disclosure: In the ordinary course of business, The Bank of New York Mellon is named as a defendant in or made a party to pending and potential legal actions. In
connection with its role as trustee of certain residential mortgage-backed securitization (RMBS) transactions, The Bank of New York Mellon was 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. While it is inherently difficult
to predict the eventual outcomes of pending actions, The Bank of New York Mellon denies liability and intends to defend the litigation vigorously.
