**Item 1117 of Regulation AB**

Disclosure from Citibank, N.A., as Certificate Administrator: 

Citibank, N.A. (“Citibank”) is acting as the Certificate Administrator of this commercial mortgage-backed securities (“CMBS”) transaction.In the ordinary course of business, Citibank is involved in a number of legal proceedings, including in connection with its role as trustee of certain residential mortgage-backed securities (“RMBS”) transactions. Certain of these Citibankas trustee-related matters are disclosed herein. 

On June 18, 2014, a civil action was filed against Citibank in the Supreme Court of the State of NewYork by a group of investors in 48 private-label RMBS trusts for which Citibank allegedly serves or did serve as trustee, asserting claims for purported violations of the Trust Indenture Act of 1939 (the “Trust Indenture Act”), breach ofcontract, breach of fiduciary duty and negligence based on Citibank’s alleged failure to perform its duties as trustee for the 48 RMBS trusts. On November 24, 2014, plaintiffs sought leave to withdraw this action. On the same day, asmaller subset of similar plaintiff investors in 27 private-label RMBS trusts for which Citibank allegedly serves or did serve as trustee, filed a new civil action against Citibank in the United States District Court for the Southern District of NewYork asserting similar claims as the prior action filed in state court. In January 2015, the court closed plaintiffs’ original state court action. On September 8, 2015, the federal court dismissed all claims as to 24 of the 27 trustsand allowed certain of the claims to proceed as to the other three trusts. Subsequently, plaintiffs voluntarily dismissed all claims with respect to two of the three trusts. On April 7, 2017, Citibank filed a motion for summary judgment.Plaintiffs filed its consolidated opposition brief and cross motion for partial summary judgment on May 22, 2017. Briefing on those motions was completed on August 4, 2017. On March 22, 2018, the court granted Citibank’s motionfor summary judgment in its entirety, denied Plaintiffs’ motion for summary judgment and ordered the clerk to close the case. On April 20, 2018, plaintiffs filed a notice of appeal. Plaintiffs’ opening brief was filed onAugust 3, 2018. Citibank filed its opposition on November 2, 2018. Plaintiffs’ filed their reply on November 16, 2018. 

OnNovember 24, 2015, the same investors that brought the federal case brought a new civil action in the Supreme Court of the State of New York related to 25 private-label RMBS trusts for which Citibank allegedly serves or did serve as trustee.This case includes the 24 trusts previously dismissed in the federal action, and one additional trust. The investors assert claims for breach of contract, breach of fiduciary duty, breach of duty to avoid conflicts of interest, and violation of NewYork’s Streit Act (the “Streit Act”). Following oral argument on Citibank’s motion to dismiss, plaintiffs filed an amended complaint on August 5, 2016. On June 27, 2017, the state court issued a decision, dismissing theevent of default claims, mortgage-file-related claims, the fiduciary duty claims, and the conflict of interest claims. The decision sustained certain breach of contract claims including the claim alleging discovery of breaches of representations andwarranties, a claim related to robo-signing, and the implied covenant of good faith claim. Citibank appealed the lower court’s decision, and on January 16, 2018, the Appellate Division, First Department, dismissed the claims related torobo-signing and the implied covenant of good faith, but allowed plaintiffs’ claim alleging discovery of breaches of representations and warranties to proceed. 

On August 19, 2015, the Federal Deposit Insurance Corporation (“FDIC”) as receiver for a failed financial institution filed a civil actionagainst Citibank in the Southern District of New York. This action relates to one private-label RMBS trust for which Citibank formerly served as trustee. FDIC asserts claims for breach of contract, violation of the Streit Act, and violation of theTrust Indenture Act. Citibank jointly briefed a motion to dismiss with The Bank of New York Mellon and U.S. Bank, N.A., entities that have also been sued by FDIC in their capacity as trustee, and these cases have all been consolidated in front ofJudge Carter. On September 30, 2016, the court granted the motion to dismiss without prejudice for lack of subject matter jurisdiction. On October 14, 2016, FDIC filed a motion for reargument or relief from judgment from the court’sdismissal order. On July 11, 2017, Judge Carter ruled on the motion for reconsideration regarding his dismissal of the action. He denied reconsideration of his decision on standing, but granted leave to amend the complaint by October 9,2017. The FDIC subsequently 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 onMarch 13, 2018. On April 18, 2018, plaintiff filed its opposition. Defendants filed their joint reply on May 3, 2018. 

There can be noassurances as to the outcome of litigation or the possible impact of litigation on the trustee or the RMBS trusts. However, Citibank denies liability and continues to vigorously defend against these litigations. Furthermore, neither theabove-disclosed litigations nor any other pending legal proceeding involving Citibank will materially affect Citibank’s ability to perform its duties as Certificate Administrator under the pooling and servicing agreement for this CMBStransaction. 

Disclosure from Deutsche Bank Trust Company Americas, as Trustee: 

Deutsche Bank Trust Company Americas (“DBTCA”) and Deutsche Bank National Trust Company (“DBNTC”) have been sued by investors in civillitigation concerning their role as trustees of certain residential mortgage-backed securities (“RMBS”) trusts. 

On June 18, 2014, a groupof investors, including funds managed by Blackrock Advisors, LLC, PIMCO-Advisors, L.P., and others, filed an action against DBNTC and DBTCA in New York State Supreme Court alleging that DBNTC and DBTCA failed to perform purported duties, as trusteesfor 544 private-label RMBS trusts, to enforce breaches of representations and warranties as to mortgage loans held by the trusts and to enforce breaches by servicers of their mortgage loan servicing obligations for the trusts. During the course ofthe litigation, plaintiffs dismissed the case from New York State Supreme Court and refiled two separate cases, one in the U.S. District Court for the Southern District of New York (the “*BlackRock*SDNY Case”) and the other in theSuperior Court of California, Orange County (the “*BlackRock*California Case”). Pursuant to a settlement among the parties, the *BlackRock*SDNY Case was dismissed on December 6, 2018 and the *BlackRock*CaliforniaCase was dismissed on January 11, 2019. 

On September 27, 2017, DBTCA was added as a defendant to a case brought by certain special purposeentities including Phoenix Light SF Limited in the U.S. District Court for the Southern District of New York, in which the plaintiffs previously alleged incorrectly that DBNTC served as trustee for all 43 of the trusts at issue. OnSeptember 27, 2017, plaintiffs filed a third amended complaint that names DBTCA as a defendant in addition to DBNTC. DBTCA serves as trustee for one of the 43 trusts at issue. 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 fiduciary duty; negligence and gross negligence; violation of New York’s Streit Act(the “Streit Act”); and breach of the covenant of good faith. However, in the third amended complaint, plaintiffs acknowledge that, before DBTCA was added to the case, the court dismissed plaintiffs’ TIA Act claims, negligence andgross negligence claims, Streit Act claims, claims for breach of the covenant of good faith, and certain theories of plaintiffs’ breach of contract claims, and plaintiffs only include these claims to preserve any rights on appeal. Plaintiffsallege damages of “hundreds of millions of dollars.” On November 13, 2017, DBNTC and 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 of *Commerzbank* case below), filed a motion for partial summary judgment. 

On November 30, 2017, DBTCA was added as a defendant to a case brought by Commerzbank AG (“Commerzbank”) in the U.S. District Court for theSouthern District of New York, in which Commerzbank previously alleged incorrectly that DBNTC served as trustee for all 50 of the trusts at issue. On November 30, 2017, Commerzbank filed a second amended complaint that names DBTCA as adefendant in addition to DBNTC. DBTCA serves as trustee for one of the 50 trusts at issue. DBNTC serves as trustee for the other 49 trusts at issue. Commerzbank’s second amended complaint brings claims for violation of the TIA; breach ofcontract; breach of fiduciary duty; negligence; violation of the Streit Act; and breach of the covenant of good faith. However, in the second amended complaint, Commerzbank acknowledges that, before DBTCA was added to the case, the court dismissedCommerzbank’s TIA claims for the trusts governed by pooling and servicing agreements, as well as its Streit Act claims and claims for breach of the covenant of good faith, and Commerzbank only includes these claims to preserve any rights onappeal. The second amended complaint alleges that DBNTC and DBTCA caused Commerzbank to suffer “hundreds of millions of dollars in losses,” but the complaint does not include a demand for money damages in a sum certain. On January 29,2018, DBNTC and DBTCA filed an answer to the second amended complaint. On December 7, 2018, DBNTC and DBTCA filed a motion for summary judgment. Also on December 7, 2018, Commerzbank, jointly with the *Phoenix Light*plaintiffs, fileda motion for partial summary judgment. 

On December 30, 2015, IKB International, S.A. in Liquidation and IKB Deutsche Industriebank A.G.(collectively, “IKB”), as an investor in 37 RMBS trusts, filed a summons with notice in the Supreme Court of the State of New York, New York County, against DBNTC and DBTCA as trustees of the trusts. On May 27, 2016, IKB served itscomplaint asserting claims for breach of contract, breach of fiduciary duty, breach of duty to avoid conflicts of interest, violation of the Streit Act, violation of the TIA, violation of Regulation AB, and violation of Section 9 of the UniformCommercial Code. IKB alleges that DBNTC and DBTCA are liable for over U.S. $268 million in damages. On October 5, 2016, DBNTC and DBTCA, together with several other trustees defending lawsuits by IKB, filed a joint motion to dismiss. OnJanuary 6, 2017 and June 20, 2017, IKB voluntarily dismissed with prejudice all claims as to seven trusts. As of March 1, 2019, DBNTC and DBTCA’s motion to dismiss has been briefed and is awaiting decision by the court. 

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

**Item 1119 of Regulation AB**

Provided previously in the prospectus supplement of the Registrant relating to the issuing entity and filed on July 8, 2015 pursuant to Rule 424(b)(5) ofthe Securities Act of 1933, as amended. 

**Item 1122 of Regulation AB**

The reports on assessment of compliance with servicing criteria for asset-backed securities and related attestation reports are attached hereto under Item 15.

The report on assessment of compliance with applicable servicing criteria furnished pursuant to Item 1122 of Regulation AB by Midland Loan Services, aDivision of PNC Bank National Association (“Midland”), as master servicer and special servicer for the Dallas Market Center mortgage loan under the GSMS 2015-GC30 PSA, and as master servicer and special servicer for the Crowne PlazaBloomington mortgage loan and the Selig Office Portfolio mortgage loan under the CGCMT 2015-GC29 PSA, discloses that a material instance of noncompliance occurred, as described below: 

Material Instance of Noncompliance 

In certaininstances, the Schedule AL Files (Item 1125 of Regulation AB) were not reported in accordance with the terms specified in the transaction agreements, in conflict with Item 1122(d)(3)(i): “Reports to investors, including those to be filed withthe Commission, are maintained in accordance with the transaction agreements and applicable Commission requirements. Specifically, such reports: (A) Are prepared in accordance with timeframes and other terms set forth in the transactionagreements”. The noncompliance consisted of omitted or inaccurately reported numbers due to the following: (1) the initial setup files contained information at the asset level, and Midland was required to manually compile the information topresent it at the loan level as required by Schedule AL; and (2) certain reporting requirements required manual processing by Midland, including the use of various data computation formulas, quality control checks and analysis. 

The identified instances did not involve the servicing of the assets backing the asset-backed securities covered in this Form 10-K report. 

Steps Taken to Remedy the Material Instance of Noncompliance 

Midland is currently remediating the Schedule AL reporting for the CMBS transactions found to be incorrect, and will be making improvements toits systems, processes and procedures to support its Schedule AL reporting obligations.
