The registrant knows of no material pending legal proceedinginvolving the trust or any party related to the trust, other than routinelitigation incidental to the duties of those respective parties, and thefollowing, with respect to Wells Fargo Bank, National Association, as trustee,as certificate administrator and as custodian.

 

In December 2014, Phoenix LightSF Limited and certain related entities and the National Credit UnionAdministration (NCUA) filed complaints in the United States District Court forthe Southern District of New York against Wells Fargo Bank, alleging claimsagainst Wells Fargo Bank in its capacity as trustee for a number of residentialmortgage-backed securities trusts. Complaints raising similar allegations havebeen filed by Commerzbank AG in the Southern District of New York and by IKBInternational and IKB Deutsche Industriebank in New York state court. In eachcase, the plaintiffs allege that Wells Fargo Bank, as trustee, caused losses toinvestors, and plaintiffs assert causes of action based upon, among otherthings, the trustee’s alleged failure to notify and enforce repurchaseobligations of mortgage loan sellers for purported breaches of representationsand warranties, notify investors of alleged events of default, and abide byappropriate standards of care following alleged events of default. Wells FargoBank previously settled two class action lawsuits with similar allegations thatwere filed in November 2014 and December 2016 by institutional investors in theSouthern District of New York and New York state court, respectively. In addition,Park Royal I LLC and Park Royal II LLC have filed complaints in New York statecourt alleging Wells Fargo Bank, N.A., as trustee, failed to take appropriateactions upon learning of defective mortgage loan documentation. In March 2021,the Company entered into an agreement to resolve the case filed by the NCUA.

 

In addition to the foregoingcases, in August 2014 and August 2015 Nomura Credit & Capital Inc. (“Nomura”)and Natixis Real Estate Holdings, LLC (“Natixis”) filed a total of seventhird-party complaints against Wells Fargo Bank in New York state court. In theunderlying first-party actions, Nomura and Natixis have been sued for allegedbreaches of representations and warranties made in connection with residentialmortgage-backed securities sponsored by them. In the third-party actions,Nomura and Natixis allege that Wells Fargo Bank, as master servicer, primaryservicer or securities administrator, failed to notify Nomura and Natixis oftheir own breaches, failed to properly oversee the primary servicers, andfailed to adhere to accepted servicing practices. Natixis additionally allegesthat Wells Fargo Bank failed to perform default oversight duties. Wells FargoBank has asserted counterclaims alleging that Nomura and Natixis failed toprovide Wells Fargo Bank notice of their representation and warranty breaches.

 

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