Wells Fargo Bank, National Association (the Indenture Trustee) has provided the
following information for inclusion in this report:

On June 18, 2014, a group of institutional investors filed a civil complaint in
the Supreme Court of the State of New York, New York County, against Wells Fargo Bank, N.A., in its capacity as trustee under 276 residential mortgage backed securities (RMBS) trusts, which was later amended on July 18, 2014, to
increase the number of trusts to 284 RMBS trusts. On November 24, 2014, the plaintiffs filed a motion to voluntarily dismiss the state court action without prejudice. That same day, a group of institutional investors filed a civil
complaint in the United States District Court for the Southern District of New York against Wells Fargo Bank, N.A., alleging claims against the bank in its capacity as trustee for 274 residential mortgage backed securities (RMBS) trusts
(the Complaint). As with the prior state court action, the Complaint is one of six similar complaints filed contemporaneously against RMBS trustees (Deutsche Bank, Citibank, HSBC, Bank of New York Mellon and US Bank) by a group of
institutional investor plaintiffs. The Complaint against Wells Fargo Bank, N.A. alleges that the trustee caused losses to investors and asserts causes of action based upon, among other things, the trustees alleged failure to (i) enforce
repurchase obligations of mortgage loan sellers for purported breaches of representations and warranties, (ii) notify investors of alleged events of default purportedly caused by breaches by mortgage loan servicers, and (iii) abide by
appropriate standards of care following alleged events of default. Relief sought includes money damages in an unspecified amount, reimbursement of expenses, and equitable relief. Other cases alleging similar causes of action have been filed against
Wells Fargo Bank, N.A. and other trustees by RMBS investors in these and other transactions.

There can be no assurances as to
the outcome of the litigation, or the possible impact of the litigation on the trustee or the RMBS trusts. However, Wells Fargo Bank, N.A. denies liability and believes that it has performed its obligations under the RMBS trusts
in good faith, that its actions were not the cause of any losses to investors, and that it has meritorious defenses, and it intends to contest the plaintiffs claims vigorously.
