ITEM 1117 OF REGULATION AB. LEGAL PROCEEDINGS

The Sponsor and the Servicer

The sponsor is subject to various pending and potential legal and regulatory proceedings in the ordinary course of business, including litigation, arbitration, claims, investigations, examinations, subpoenas and enforcement proceedings. Some litigation against the sponsor could take the form of class actions. The outcome of these proceedings is inherently uncertain, and thus the sponsor cannot confidently predict how or when proceedings will be resolved. An adverse outcome in one or more of these proceedings could result in substantial damages, settlements, fines, penalties, diminished income or reputational harm to the sponsor, and could materially and adversely affect the interests of the noteholders or the servicer’s ability to perform its duties under the Transaction Documents.

The Trustee and the Trust Collateral Agent

In December 2014, Phoenix Light SF Limited and certain related entities and the National Credit Union Administration filed complaints in the United States District Court for the Southern District of New York against Wells Fargo, alleging claims against Wells Fargo in its capacity as trustee for a number of residential mortgage-backed securities trusts. Complaints raising similar allegations have been filed by Commerzbank AG in the Southern District of New York and by IKB International and IKB Deutsche Industriebank in New York state court. In each case, the plaintiffs allege that Wells Fargo, 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. Wells Fargo previously settled two class action lawsuits with similar allegations that were filed in November 2014 and December 2016 by institutional investors in the Southern District of New York and New York state court, respectively.

In addition to the foregoing cases, in August 2014 and August 2015 Nomura Credit & Capital Inc., or Nomura, and Natixis Real Estate Holdings, LLC, or Natixis, filed a total of seven third-party complaints against Wells Fargo in New York state court. In the underlying first-party actions, Nomura and Natixis have been sued for alleged breaches of representations and warranties made in connection with residential mortgage-backed securities sponsored by them. In the third-party actions, Nomura and Natixis allege that Wells Fargo, as master servicer, primary servicer or securities administrator, failed to notify Nomura and Natixis of their own breaches, failed to properly oversee the primary servicers, and failed to adhere to accepted

servicing practices. Natixis additionally alleges that Wells Fargo failed to perform default oversight duties. Wells Fargo has asserted counterclaims alleging that Nomura and Natixis failed to provide Wells Fargo notice of their representation and warranty breaches.

With respect to each of the foregoing litigations, Wells Fargo believes the plaintiffs’ claims are without merit and intends to contest the claims vigorously, but there can be no assurances as to the outcome of the litigations or the possible impact of the litigations on Wells Fargo or the related RMBS trusts.
