On June 18, 2014, a group ofinstitutional investors filed a civil complaint in the Supreme Court of theState of New York, New York County, against Wells Fargo Bank, N.A. (“WellsFargo Bank”), in its capacity as trustee under 276 residential mortgagebacked securities (“RMBS”) trusts, which was later amendedon July 18, 2014, to increase the number of trusts to 284 RMBS trusts. OnNovember 24, 2014, the plaintiffs filed a motion to voluntarily dismiss thestate court action without prejudice. That same day, a group of institutionalinvestors filed a putative class action complaint in the United States DistrictCourt for the Southern District of New York (the “District Court”)against Wells Fargo Bank, alleging claims against the bank in its capacity astrustee for 274 RMBS trusts (the “Federal Court Complaint”).In December 2014, the plaintiffs’ motion to voluntarily dismiss theiroriginal state court action was granted. As with the prior state court action,the Federal Court Complaint is one of six similar complaints filedcontemporaneously against RMBS trustees (Deutsche Bank, Citibank, HSBC, Bank ofNew York Mellon and US Bank) by a group of institutional investor plaintiffs.The Federal Court Complaint against Wells Fargo Bank alleges that the trusteecaused losses to investors and asserts causes of action based upon, among otherthings, the trustee's alleged failure to: (i) notify and enforce repurchaseobligations of mortgage loan sellers for purported breaches of representationsand warranties, (ii) notify investors of alleged events of default, and (iii)abide by appropriate standards of care following alleged events of default.Relief sought includes money damages in an unspecified amount, reimbursement ofexpenses, and equitable relief. Other cases alleging similar causes of actionhave been filed against Wells Fargo Bank and other trustees in the DistrictCourt by RMBS investors in these and other transactions, and these casesagainst Wells Fargo Bank are proceeding before the same District Court judge. Asimilar complaint was also filed May 27, 2016 in New York state court by adifferent plaintiff investor. On January 19, 2016, an order was entered inconnection with the Federal Court Complaint in which the District Courtdeclined to exercise jurisdiction over 261 trusts at issue in the Federal CourtComplaint; the District Court also allowed plaintiffs to file amendedcomplaints as to the remaining, non-dismissed trusts, if they so chose, andthree amended complaints have been filed. On December 17, 2016, the investorplaintiffs in the 261 trusts dismissed from the Federal Court Complaint filed anew complaint in New York state court (the “State Court Complaint”).Motions to dismiss all of the actions are pending except for the recently filedState Court Complaint. There can be no assurances as to the outcome of thelitigations, or the possible impact of the litigations on the trustee or theRMBS trusts. However, Wells Fargo Bank denies liability and believes that ithas performed its obligations under the RMBS trusts in good faith, that itsactions were not the cause of any losses to investors, and that it hasmeritorious defenses, and it intends to contest the plaintiffs’ claimsvigorously.

 

On February 23, 2016, acertificate holder of the J.P. Morgan Chase Commercial Mortgage SecuritiesTrust, Series 2007-CIBC18 (the “Trust”) filed suit in theSupreme Court of New York, County of New York, against KeyBank NationalAssociation and Berkadia Commercial Mortgage LLC (collectively, the “Servicers”). The suit was filed derivatively on behalf of the Trust.  The action wasbrought in connection with the Servicers’ determination of the fair valueof a loan, secured by the Bryant Park Hotel in New York City, held by the Trustand sold to an assignee of the Trust’s directing certificate holder,pursuant to an exercise of the fair value option set forth in the Pooling andServicing Agreement governing the Trust.  There can be no assurances as tothe outcome of the action or the possible impact of the litigation on theServicers.  Both Servicers deny liability, believe that they performedtheir obligations in accordance with the terms of the Pooling and ServicingAgreement, and have contested the claims asserted against them, filing a motionto dismiss the case.  On November 28, 2016, the Servicers’ motion todismiss was granted.  The plaintiff certificate holder has filed a noticeof appeal, and the appeal is pending.

 

On May 12, 2016, certain holders of certificates issued byCredit Suisse First Boston Mortgage Securities Corp. Commercial MortgagePass-Through Series 2007-C5 Trust (the “2007-C5 Trust“)filed suit in the Supreme Court of the State of New York, County of New Yorkderivatively for the 2007-C5 Trust (M.H. Davidson & Co, et. al. against C-IIIAsset Management, LLC (“C-III AM”), Supreme Court of NewYork County of New York Index No. 652571/2016) alleging, among other things,that C-III AM as special servicer for the 2007-C5 Trust breached its duties tothe 2007-C5 Trust by undervaluing a mortgage loan which was purchased by thethird party directing certificateholder for the 2007-C5 Trust pursuant to thegoverning pooling and servicing agreement.
