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. Inaddition, Park Royal I LLC and Park Royal II LLC have filed complaints in NewYork state court alleging Wells Fargo Bank, N.A., as trustee, failed to takeappropriate actions upon learning of defective mortgage loan documentation. InMarch 2021, the Company entered into an agreement to resolve the case filed bythe 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, Wells Fargo Bank believesplaintiffs' claims are without merit and intends to contest the claimsvigorously, but there can be no assurances as to the outcome of the litigationsor the possible impact of the litigations on Wells Fargo Bank or the relatedRMBS trusts.

From time to time, CWCapital Asset Management LLC, a Delawarelimited liability company (“CWCAM”), is a party to lawsuits and otherlegal proceedings as part of its duties as a special servicer (e.g.,enforcement of loan obligations) and/or arising in the ordinary course ofbusiness.  Other than as set forth in the following paragraphs, there arecurrently no legal proceedings pending, and no legal proceedings known to becontemplated by governmental authorities, against CWCAM or of which any of itsproperty is the subject, that are material to the certificateholders.

On December 17, 2015, U.S. Bank National Association, thetrustee under five pooling and servicing agreements for (i) Wachovia BankCommercial Mortgage Trust 2007-C30, (ii) COBALT CMBS Commercial Trust 2007-C2,(iii) Wachovia Bank Commercial Mortgage Trust 2007-C31, (iv) ML-CFC CommercialMortgage Trust 2007-5 and (v) ML-CFC Commercial Mortgage Trust 2007-6 commenceda proceeding with the Second Judicial District Court of Ramsey County,Minnesota (the “State Court”) for a declaratory judgment as to theproper allocation of certain proceeds (“Disputed Proceeds”) received byCWCAM in connection with the sale of the Peter Cooper Village and StuyvesantTown property in New York, New York securing loans held by those trusts. CWCAM was the special servicer of such property.  The petition requeststhe State Court to instruct the trustee, the trust beneficiaries, and any otherinterested parties as to the amount of the Disputed Proceeds, if any, that constitutepenalty interest and/or the amount of the Disputed Proceeds, if any, thatconstitute gain-on-sale proceeds, with respect to each trust.  On February24, 2016, CWCAM made a limited appearance with the State Court to file a motionto dismiss this proceeding based on lack of jurisdiction, mootness, standingand forum non conveniens.  On July 19, 2016, the State Court deniedCWCAM’s motion to dismiss.  On July 22, 2016, the action was removed tofederal court in Minnesota (“Federal Court”).  On October 21, 2016,the Federal Court held a hearing on the motion to transfer the action to theUnited States District Court for the Southern District of New York (“SDNYCourt”), a motion to remand to state court and a motion to hear CWCAM’srequest for reconsideration of the motion to dismiss.  On March 14, 2017,the Federal Court reserved the determination on the motion to hear CWCAM’srequest for reconsideration of the motion to dismiss, denied the motion toremand the matter to state court and granted the motion to transfer theproceeding to the SDNY Court.  Cross motions for judgment on the pleadingswere filed but the SDNY Court was unable to decide the case based on thepleadings and the SDNY Court ordered discovery.  All fact discovery wascompleted in December, 2018 and expert discovery was completed on March 15,2019.
