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 trustee 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 Schedule AL Files (Item 1125 ofRegulation AB) were not reported in accordance with the terms specified in thetransaction agreements, in conflict with Item 1122(d)(3)(i): “Reports toinvestors, including those to be filed with the Commission, are maintained inaccordance with the transaction agreements and applicable Commissionrequirements. Specifically, such reports: (A) Are prepared in accordance withtimeframes and other terms set forth in the transaction agreements”.  Thenoncompliance consisted of omitted or inaccurately reported fields as describedin (1) and (2) below.  (1) In connection with other enhancements Midlandmade to its manual Schedule AL process, starting in April 2019, Midlanddeveloped and implemented new Schedule AL reporting templates for eachapplicable CMBS transaction that closed prior to April 2019 and for eachapplicable CMBS transaction going forward.  Related to this, Midland madecertain template setup errors, along with related and other manual inputting ofinformation errors, and the errors were not identified prior to submission ofthe applicable Schedule AL Files in certain cases due to breakdowns in qualitycontrol.  (2) In one applicable transaction, the related Schedule AL Filefor 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 not involve the servicing ofassets included in this securitization.

Steps Taken to Remedy the Material Instance of Noncompliance

Midland’s Schedule AL reporting process was enhanced in Aprilof 2019, however, the process remained manual throughout the 2019 calendaryear.  Errors relating to certain Schedule AL Files during 2019 wereidentified during the related audit.  Following identification, Midlandmade staffing changes and additional enhancements and improvements to itsprocesses and procedures to support its Schedule AL reporting obligations andexpects to move to an automated solution for this process.  

Midland is currently remediating the Schedule AL reportingfor certain of the CMBS transactions found to be incorrect.
