**Item 1117 of Regulation AB, Legal Proceedings.**

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, as trustee,as certificate administrator and as custodian.

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 atissue.  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 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 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 forthe given month instead of the correct Schedule AL File. 

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

Steps Taken to Remedy the Material 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 currently remediating theSchedule AL reporting for certain of the CMBS transactions found to beincorrect.
