The registrant knows ofno material pending legal proceeding involving the trust or any party relatedto the trust, other than routine litigation incidental to the duties of thoserespective parties, and the following, with respect to Citibank, as custodian,and Wells Fargo Bank, National Association, as certificate administrator, astrustee, and as custodian.

In the ordinary course ofbusiness, Citibank is involved in a number of legal proceedings, including inconnection with its role as trustee of certain RMBS transactions.  Certainof these Citibank as trustee-related matters are disclosed herein. 

On June 18, 2014, a civilaction was filed against Citibank in the Supreme Court of the State of New Yorkby a group of investors in 48 private-label RMBS trusts for which Citibankallegedly serves or did serve as trustee, asserting claims for purportedviolations of the Trust Indenture Act of 1939 (the “Trust Indenture Act”),breach of contract, breach of fiduciary duty and negligence based on Citibank’salleged failure to perform its duties as trustee for the 48 RMBS trusts. On November 24, 2014, plaintiffs sought leave to withdraw this action.  Onthe same day, a smaller subset of similar plaintiff investors in 27private-label RMBS trusts for which Citibank allegedly serves or did serve astrustee, filed a new civil action against Citibank in the United StatesDistrict Court for the Southern District of New York asserting similar claimsas the prior action filed in state court.  In January 2015, the courtclosed plaintiffs’ original state court action.  On September 8, 2015, thefederal court dismissed all claims as to 24 of the 27 trusts and allowed certainof the claims to proceed as to the other three trusts. Subsequently, plaintiffsvoluntarily dismissed all claims with respect to two of the three trusts. OnApril 7, 2017, Citibank filed a motion for summary judgment. Plaintiffs filedits consolidated opposition brief and cross motion for partial summary judgmenton May 22, 2017.  Briefing on those motions was completed on August 4,2017. On March 22, 2018, the court granted Citibank’s motion for summaryjudgment in its entirety, denied Plaintiffs’ motion for summary judgment andordered the clerk to close the case. On April 20, 2018, plaintiffs filed anotice of appeal. Plaintiffs’ opening brief was filed on August 3, 2018.Citibank filed its opposition on November 2, 2018.  Plaintiffs’ filedtheir reply on November 16, 2018.  On June 7, 2019, the Second Circuitdismissed plaintiffs’ appeal following the parties’ filing of a stipulationwithdrawing the case with prejudice pursuant to Federal Rule of AppellateProcedure 42.

On November 24, 2015, thesame investors that brought the federal case brought a new civil action in theSupreme Court of the State of New York related to 25 private-label RMBS trustsfor which Citibank allegedly serves or did serve as trustee.  This caseincludes the 24 trusts previously dismissed in the federal action, and oneadditional trust.  The investors assert claims for breach of contract,breach of fiduciary duty, breach of duty to avoid conflicts of interest, andviolation of New York’s Streit Act (the “Streit Act”).  Following oral argumenton Citibank’s motion to dismiss, Plaintiffs filed an amended complaint onAugust 5, 2016.  On June 27, 2017, the state court issued a decision,dismissing the Event of Default claims, mortgage-file-related claims, thefiduciary duty claims, and the conflict of interest claims.  The decisionsustained certain breach of contract claims including the claim allegingdiscovery of breaches of representations and warranties, a claim related torobo-signing, and the implied covenant of good faith claim.  Citibankappealed the lower court’s decision, and on January 16, 2018, the AppellateDivision, First Department, dismissed the claims related to robo-signing andthe implied covenant of good faith, but allowed plaintiffs’ claim allegingdiscovery of breaches of representations and warranties to proceed.  OnJune 7, 2019, plaintiffs filed a motion for discontinuance of the action anddismissal of plaintiffs’ claims with prejudice.

On August 19, 2015, theFederal Deposit Insurance Corporation (“FDIC”) as Receiver for a failedfinancial institution filed a civil action against Citibank in the SouthernDistrict of New York.  This action relates to one private-label RMBS trustfor which Citibank formerly served as trustee.  FDIC asserts claims forbreach of contract, violation of the Streit Act, and violation of the TrustIndenture Act. Citibank jointly briefed a motion to dismiss with The Bank ofNew York Mellon and U.S. Bank, N.A., entities that have also been sued by FDICin their capacity as trustee, and these cases have all been consolidated infront of Judge Carter.  On September 30, 2016, the Court granted themotion to dismiss without prejudice for lack of subject matterjurisdiction.  On October 14, 2016, FDIC filed a motion for reargument orrelief from judgment from the Court’s dismissal order.  On July 11, 2017,Judge Carter ruled on the motion for reconsideration regarding his dismissal ofthe action.  He denied reconsideration of his decision on standing, butgranted leave to amend the complaint by October 9, 2017.  The FDICsubsequently requested an extension of time to file its amended complaint,which was granted. The FDIC filed its amended complaint on December 8, 2017.Defendants’ jointly filed a motion to dismiss the amended complaint and that jointmotion was fully briefed as of May 3, 2018.  On March 20, 2019, the Courtgranted Defendants’ joint motion to dismiss the amended complaint. The FDIC'sdeadline to file a notice of appeal was April 22, 2019. The FDIC has notappealed. 

There can be no assurancesas to the outcome of litigation or the possible impact of litigation on thetrustee or the RMBS trusts.  However, Citibank denies liability andcontinues to vigorously defend against these litigations.  Furthermore,neither the above-disclosed litigations nor any other pending legal proceedinginvolving Citibank will materially affect Citibank’s ability to perform itsduties under the related servicing agreement for this CMBS transaction.

Beginning on June 18,2014, a group of institutional investors filed civil complaints in the SupremeCourt of the State of New York, New York County, and later the U.S. DistrictCourt for the Southern District of New York, against Wells Fargo Bank, N.A.,(“Wells Fargo Bank”) in its capacity as trustee for certain residentialmortgage backed securities (“RMBS”) trusts.  The complaints against WellsFargo Bank alleged that the trustee caused losses to investors and assertedcauses 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 included money damages in anunspecified amount, reimbursement of expenses, and equitable relief. InNovember 2018, Wells Fargo Bank reached an agreement, in which it denied anywrongdoing, to resolve such claims on a classwide basis for the 271 RMBS trustsat issue.  On May 6, 2019, the court entered an order approving thesettlement agreement.  Separate lawsuits against Wells Fargo Bank makingsimilar allegations filed by certain other institutional investors concerningseveral RMBS trusts in New York federal and state court are not covered by theagreement.  With respect to such 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 RMBStrusts.

The report on assessmentof compliance with applicable servicing criteria furnished pursuant to Item1122 of Regulation AB by Midland Loan Services, a Division of PNC Bank NationalAssociation (“Midland”) discloses that a material instance of noncomplianceoccurred, as described below:

Material Instance ofNoncompliance

In certain instances, theSchedule AL Files (Item 1125 of Regulation AB) were not reported in accordancewith the terms specified in the transaction agreements, in conflict with Item1122(d)(3)(i): “Reports to investors, including those to be filed with theCommission, are maintained in accordance with the transaction agreements andapplicable Commission requirements. Specifically, such reports: (A) Areprepared in accordance with timeframes and other terms set forth in thetransaction agreements”.  The noncompliance consisted of omitted orinaccurately reported fields as described in (1) and (2) below.  (1) Inconnection with other enhancements Midland made to its manual Schedule ALprocess, starting in April 2019, Midland developed and implemented new ScheduleAL reporting templates for each applicable CMBS transaction that closed priorto April 2019 and for each applicable CMBS transaction going forward. Related to this, Midland made certain template setup errors, along with relatedand other manual inputting of information errors, and the errors were notidentified prior to submission of the applicable Schedule AL Files in certaincases due to breakdowns in quality control.  (2) In one applicabletransaction, the related Schedule AL File for a given month was not savedproperly resulting in the prior month's Schedule AL File being submitted for thegiven month instead of the correct Schedule AL File. 

The identified instancesdid not involve the servicing of assets included in this securitization.

Steps Taken to Remedy theMaterial Instance of Noncompliance

Midland’s Schedule AL reportingprocess was enhanced in April of 2019, however, the process remained manualthroughout the 2019 calendar year.  Errors relating to certain Schedule ALFiles during 2019 were identified during the related audit.  Followingidentification, Midland made staffing changes and additional enhancements andimprovements to its processes and procedures to support its Schedule ALreporting obligations and expects to move to an automated solution for thisprocess.  

Midland is currentlyremediating the Schedule AL reporting for certain of the CMBS transactionsfound to be incorrect.
