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, certainholders of certificates issued by Credit Suisse First Boston MortgageSecurities Corp. Commercial Mortgage Pass-Through Series 2007-C5 Trust (the“2007-C5 Trust“) filed suit in the Supreme Court of theState of New York, County of New York derivatively for the 2007-C5 Trust (M.H.Davidson & Co, et. al. against C-III Asset Management, LLC (“C-IIIAM”), Supreme Court of New York County of New York Index No.652571/2016) alleging, among other things, that C-III AM as special servicerfor the 2007-C5 Trust breached its duties to the 2007-C5 Trust by undervaluinga mortgage loan which was purchased by the third party directingcertificateholder for the 2007-C5 Trust pursuant to the governing pooling andservicing agreement. The plaintiffs have alleged damages in an amount no lessthan $25,000,000.  On July 1, 2016, C-III AM filed a motion todismiss.  A hearing on the motion was held on March 6, 2017, and ispending a ruling.  There can be no assurances as to the outcome of this motionor the proceeding or the possible impact on C-III AM. However, C-III AMbelieves that it performed its obligations under the related pooling andservicing agreement in good faith, and that its actions were proper. C-III AM believes the plaintiffs’ claims are unfounded and intends tovigorously defend itself and contest the claims.

 

On June 18, 2014, a group of institutional investors filed acivil complaint in the Supreme Court of the State of New York, New York County,against Wells Fargo Bank, N.A. (“Wells Fargo Bank”), in itscapacity as trustee under 276 residential mortgage backed securities (“RMBS”)trusts, which was later amended on July 18, 2014, to increase the number oftrusts to 284 RMBS trusts. On November 24, 2014, the plaintiffs filed a motionto voluntarily dismiss the state court action without prejudice. That same day,a group of institutional investors filed a putative class action complaint inthe United States District Court for the Southern District of New York (the“District Court”) against Wells Fargo Bank, alleging claimsagainst the bank in its capacity as trustee for 274 RMBS trusts (the “FederalCourt Complaint”). In December 2014, the plaintiffs’ motion tovoluntarily dismiss their original state court action was granted. As with theprior state court action, the Federal Court Complaint is one of six similarcomplaints filed contemporaneously against RMBS trustees (Deutsche Bank,Citibank, HSBC, Bank of New York Mellon and US Bank) by a group ofinstitutional investor plaintiffs. The Federal Court Complaint against WellsFargo Bank alleges that the trustee caused losses to investors and assertscauses of action based upon, among other things, the trustee's alleged failureto: (i) notify and enforce repurchase obligations of mortgage loan sellers forpurported breaches of representations and warranties, (ii) notify investors ofalleged events of default, and (iii) abide by appropriate standards of carefollowing alleged events of default. Relief sought includes money damages in anunspecified amount, reimbursement of expenses, and equitable relief. Othercases alleging similar causes of action have been filed against Wells FargoBank and other trustees in the District Court by RMBS investors in these andother transactions, and these cases against Wells Fargo Bank are proceedingbefore the same District Court judge. A similar complaint was also filed May27, 2016 in New York state court by a different plaintiff investor. On January19, 2016, an order was entered in connection with the Federal Court Complaintin which the District Court declined to exercise jurisdiction over 261 trustsat issue in the Federal Court Complaint; the District Court also allowedplaintiffs to file amended complaints as to the remaining, non-dismissed trusts,if they so chose, and three amended complaints have been filed. On December 17,2016, the investor plaintiffs in the 261 trusts dismissed from the FederalCourt Complaint filed a new complaint in New York state court (the “StateCourt Complaint”). Motions to dismiss all of the actions are pendingexcept for the recently filed State Court Complaint. There can be no assurancesas to the outcome of the litigations, or the possible impact of the litigationson the trustee or the RMBS trusts. However, Wells Fargo Bank denies liabilityand believes that it has performed its obligations under the RMBS trusts ingood faith, that its actions were not the cause of any losses to investors, andthat it has meritorious defenses, and it intends to contest the plaintiffs’claims vigorously.
