PART II – OTHER INFORMATION

Item 2. Legal Proceedings.

Wells Fargo Bank, National Association 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, National Association, in its capacity as trustee under 276 residential mortgage backed securities (“RMBS”) trusts. 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 certain of the institutional investor plaintiffs. The complaint against Wells Fargo Bank, National Association alleges the trustee caused losses to investors and asserts causes of action based upon, among other things, the trustee’s purported failure to enforce repurchase obligations of mortgage loan sellers for alleged breaches of representations and warranties concerning loan quality, failure to notify securityholders of purported events of default allegedly caused by breaches by mortgage loan servicers and purported failure to abide by appropriate standards of care following events of default. Relief sought includes money damages in an unspecified amount, reimbursement of certain expenses and equitable relief. Other cases alleging similar causes of action have previously been filed against Wells Fargo Bank, National Association and other trustees by RMBS investors in 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, National Association 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 losses to investors and that it has meritorious defenses, and it intends to contest the plaintiffs’ claims vigorously.
