Deutsche Bank Trust CompanyAmericas acts as trustee of the mortgage loans serviced under the Pooling andServicing Agreement. Pursuant to the Pooling and Servicing Agreement, thetrustee is required to provide an assessment of compliance with applicableservicing criteria solely with respect to Item 1122(d)(2)(iii) of Regulation AB(regarding advances of funds or guarantees regarding collections, cash flows ordistributions, and any interest or other fees charged for such advances, aremade, reviewed and approved as specified in the transaction agreements).However, during the reporting period, the trustee did not perform any servicingfunction with respect to the servicing criteria specified in Item1122(d)(2)(iii) of Regulation AB. The master servicer or the special servicer,to the extent required, performed the servicing function identified withrespect to Item 1122(d)(2)(iii) of Regulation AB, and each such party includedItem 1122(d)(2)(iii) of Regulation AB in the assessment of compliance withapplicable servicing criteria and accountant’s attestation report for thesubject transaction. As a result, this Annual Report on Form 10-K does notinclude an assessment of compliance with applicable servicing criteria of thetrustee. One or more other servicers of the mortgage loans serviced under thePooling and Servicing Agreement have delivered one or more assessments of compliancewith respect to Item 1122(d)(2)(iii) of Regulation AB.

This Annual Report on Form 10-Kincludes assessments of compliance with applicable servicing criteria andaccountants’ attestation reports from CoreLogic Commercial Real EstateServices, Inc. and National Tax Search, LLC. These entities were engagedby the master servicer under the Pooling and Servicing Agreement to remit taxpayments received from the escrow accounts of borrowers to local taxingauthorities, to report tax amounts due, to verify tax parcel information, andto verify non-escrow tax payments. These servicing functions are includedwithin the servicing criteria set forth in Items 1122(d)(4)(xi) and1122(d)(4)(xii) of Regulation AB. Therefore, under the principles-baseddefinition of “servicer” set forth in Item 1101(j) of Regulation AB that looksto the functions that an entity performs, these vendors are “servicers” for thepurposes of Item 1122 of Regulation AB. *See* Compliance andDisclosure Interpretations, Section 301.01 (Item 1101(j)).

**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 Deutsche Bank Trust Company Americas, as trustee andWells Fargo Bank, National Association, as certificate administrator andcustodian:

Deutsche Bank Trust Company Americas (“DBTCA”) andDeutsche Bank National Trust Company (“DBNTC”) have been sued byinvestors in civil litigation concerning their role as trustees of certain RMBStrusts. 

On June 18, 2014, a group of investors, including fundsmanaged by Blackrock Advisors, LLC, PIMCO-Advisors, L.P., and others, filed anaction against DBNTC and DBTCA in New York State Supreme Court alleging thatDBNTC and DBTCA failed to perform purported duties, as trustees for 544private-label RMBS trusts, to enforce breaches of representations andwarranties as to mortgage loans held by the trusts and to enforce breaches byservicers of their mortgage loan servicing obligations for the trusts. During the course of the litigation, plaintiffs dismissed the case from NewYork State Supreme Court and refiled two separate cases, one in the U.S.District Court for the Southern District of New York (the “BlackRock SDNYCase”) and the other in the Superior Court of California, Orange County(the “BlackRock California Case”).  Pursuant to a settlement amongthe parties, the BlackRock SDNY Case was dismissed on December 6, 2018 and theBlackRock California Case was dismissed on January 11, 2019.

On September 27, 2017, DBTCA was added as a defendant to acase brought by certain special purpose entities including Phoenix Light SFLimited in the U.S. District Court for the Southern District of New York, inwhich the plaintiffs previously alleged incorrectly that DBNTC served astrustee for all 43 of the trusts at issue.  On September 27, 2017,plaintiffs filed a third amended complaint that names DBTCA as a defendant inaddition to DBNTC.  DBTCA serves as trustee for one of the 43 trusts atissue.  DBNTC serves as trustee for the other 42 trusts at issue. Plaintiffs’ third amended complaint brings claims for violation of the U.S.Trust Indenture Act of 1939 (“TIA”); breach of contract; breach of fiduciaryduty; negligence and gross negligence; violation of New York’s Streit Act; andbreach of the covenant of good faith.  However, in the third amendedcomplaint, plaintiffs acknowledge that, before DBTCA was added to the case, thecourt dismissed plaintiffs’ TIA Act claims, negligence and gross negligenceclaims, Streit Act claims, claims for breach of the covenant of good faith, andcertain theories of plaintiffs’ breach of contract claims, and plaintiffs onlyinclude these claims to preserve any rights on appeal.  Plaintiffs allegedamages of “hundreds of millions of dollars.”  On November 13, 2017, DBNTCand DBTCA filed an answer to the third amended complaint.  On December 7,2018, DBNTC and DBTCA filed a motion for summary judgment.  Also onDecember 7, 2018, plaintiffs, jointly with Commerzbank AG (see description ofCommerzbank case below), filed a motion for partial summary judgment.

On November 30, 2017, DBTCA was added as a defendant to acase brought by Commerzbank AG (“Commerzbank”) in the U.S. DistrictCourt for the Southern District of New York, in which Commerzbank previouslyalleged incorrectly that DBNTC served as trustee for all 50 of the trusts atissue.  On November 30, 2017, Commerzbank filed a second amended complaintthat names DBTCA as a defendant in addition to DBNTC.  DBTCA serves astrustee for 1 of the 50 trusts at issue.  DBNTC serves as trustee for theother 49 trusts at issue.  Commerzbank’s second amended complaint bringsclaims for violation of the TIA; breach of contract; breach of fiduciary duty;negligence; violation of the Streit Act; and breach of the covenant of goodfaith.  However, in the second amended complaint, Commerzbank acknowledgesthat, before DBTCA was added to the case, the court dismissed Commerzbank’s TIAclaims for the trusts governed by pooling and servicing agreements, as well asits Streit Act claims and claims for breach of the covenant of good faith, andCommerzbank only includes these claims to preserve any rights on appeal. The second amended complaint alleges that DBNTC and DBTCA caused Commerzbank tosuffer “hundreds of millions of dollars in losses,” but the complaint does notinclude a demand for money damages in a sum certain.  On January 29, 2018,DBNTC and DBTCA filed an answer to the second amended complaint.  OnDecember 7, 2018, DBNTC and DBTCA filed a motion for summary judgment. Also on December 7, 2018, Commerzbank, jointly with the Phoenix Lightplaintiffs, filed a motion for partial summary judgment.

On December 30, 2015, IKB International, S.A. in Liquidationand IKB Deutsche Industriebank A.G. (collectively, “IKB”), as aninvestor in 37 RMBS trusts, filed a summons with notice in the Supreme Court ofthe State of New York, New York County, against DBNTC and DBTCA as trustees ofthe trusts.  On May 27, 2016, IKB served its complaint asserting claimsfor breach of contract, breach of fiduciary duty, breach of duty to avoidconflicts of interest, violation of the Streit Act, violation of the TIA, violationof Regulation AB, and violation of Section 9 of the Uniform CommercialCode.  IKB alleges that DBNTC and DBTCA are liable for over U.S. $268million in damages.  On October 5, 2016, DBNTC and DBTCA, together withseveral other trustees defending lawsuits by IKB, filed a joint motion todismiss.  On January 6, 2017 and June 20, 2017, IKB voluntarily dismissedwith prejudice all claims as to seven trusts.  As of March 1, 2019, DBNTCand DBTCA’s motion to dismiss has been briefed and is awaiting decision by thecourt.

It is DBTCA’s belief that it has no pending legal proceedings(including, based on DBTCA’s present evaluation, the litigation disclosed inthe foregoing paragraphs) that would materially affect its ability to performits duties under the related servicing agreement for this transaction.

Since June 18, 2014, a group of institutional investors havefiled civil complaints in the Supreme Court of the State of New York, New YorkCounty, and later the U.S. District Court for the Southern District of New Yorkagainst Wells Fargo Bank, N.A., (“Wells Fargo Bank”) in its capacity astrustee 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. Wells Fargo Bank hasreached an agreement, in which it denies any wrongdoing, to resolve theseclaims on a classwide basis for the 271 RMBS trusts currently at issue. The settlement agreement is subject to court approval.  Separate lawsuitsagainst Wells Fargo Bank making similar allegations filed by certain otherinstitutional investors concerning 57 RMBS trusts in New York federal and statecourt are not covered by the agreement.  With respect to the foregoinglitigations, Wells Fargo Bank believes plaintiffs' claims are without merit andintends to contest the claims vigorously, but there can be no assurances as tothe outcome of the litigations or the possible impact of the litigations onWells Fargo Bank or the RMBS trusts.
