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, ascertificate administrator, as custodian and as trustee.

Beginning on June 18, 2014, a group of institutionalinvestors filed civil complaints in the Supreme Court of the State of New York,New York County, and later the U.S. District Court for the Southern District ofNew York, against Wells Fargo Bank, N.A., (“Wells Fargo Bank”) in itscapacity as trustee for certain residential mortgage backed securities (“RMBS”)trusts.  The complaints against Wells Fargo Bank alleged that the trusteecaused losses to investors and asserted causes of action based upon, amongother things, the trustee's alleged failure to: (i) notify and enforcerepurchase obligations of mortgage loan sellers for purported breaches ofrepresentations and warranties, (ii) notify investors of alleged events ofdefault, and (iii) abide by appropriate standards of care following allegedevents of default. Relief sought included money damages in an unspecifiedamount, reimbursement of expenses, and equitable relief. In November 2018,Wells Fargo Bank reached an agreement, in which it denied any wrongdoing, toresolve such claims on a classwide basis for the 271 RMBS trusts at issue. On May 6, 2019, the court entered an order approving the settlementagreement.  Separate lawsuits against Wells Fargo Bank making similarallegations filed by certain other institutional investors concerning severalRMBS 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 assessment of compliance with applicableservicing criteria furnished pursuant to Item 1122 of Regulation AB by MidlandLoan Services, a Division of PNC Bank National Association (“Midland”)discloses that a material instance of noncompliance occurred, as describedbelow:

Material Instance of Noncompliance

In certain instances, the ScheduleAL Files (Item 1125 of Regulation AB) were not reported in accordance with theterms 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 and applicableCommission requirements. Specifically, such reports: (A) Are prepared inaccordance with timeframes and other terms set forth in the transactionagreements”.  The noncompliance consisted of omitted or inaccuratelyreported fields as described in (1) and (2) below.  (1) In connection withother enhancements Midland made to its manual Schedule AL process, starting inApril 2019, Midland developed and implemented new Schedule AL reportingtemplates for each applicable CMBS transaction that closed prior to April 2019and for each applicable CMBS transaction going forward.  Related to this,Midland made certain template setup errors, along with related and other manualinputting of information errors, and the errors were not identified prior to submissionof the applicable Schedule AL Files in certain cases due to breakdowns inquality control.  (2) In one applicable transaction, the related ScheduleAL File for a given month was not saved properly resulting in the prior month'sSchedule AL File being submitted for the given month instead of the correctSchedule AL File. 

The identified instances did notinvolve the servicing of assets included in this securitization.
