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 Citibank
as 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
New York 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 U.S. Trust Indenture Act of 1939, as amended (the Trust Indenture
Act), breach of contract, 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, a smaller 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 New York 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 trusts and 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 November 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 New York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 the event 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 and warranties, 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 to robo-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 action against 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 the Trust 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 of Judge Carter. On September 30, 2016, the court granted Citibanks motion to dismiss the complaint 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s dismissal 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.

There can be no assurances 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 the above-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 CMBS transaction.

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 civil litigation concerning their role as trustees of certain residential mortgage-backed securities (RMBS) trusts.

On
June 18, 2014, a group of investors, including funds managed by Blackrock Advisors, LLC, PIMCO-Advisors, L.P., and others, filed a derivative action against DBNTC and DBTCA in New York State Supreme Court purportedly on behalf of and for the
benefit of 544 private-label RMBS trusts asserting claims for alleged violations of the U.S. Trust Indenture Act of 1939 (the Trust Indenture Act), breach of contract, breach of fiduciary duty and negligence based on DBNTC and
DBTCAs alleged failure to perform their duties as trustees for the trusts. Plaintiffs subsequently dismissed their state court complaint and filed a derivative and class action complaint in the U.S. District Court for the Southern District of
New York on behalf of and for the benefit of 564 private-label RMBS trusts, which substantially overlapped with the trusts at issue in the state court action. The complaint alleges that the trusts at issue have suffered total realized collateral
losses of U.S. $89.4 billion, but the complaint does not include a demand for money damages in a sum certain. DBNTC and DBTCA filed a motion to dismiss, and on January 19, 2016, the court partially granted the motion on procedural grounds:
as to the 500 trusts that are governed by pooling and servicing agreements, the court declined to exercise jurisdiction. The court did not rule on substantive defenses asserted in the motion to dismiss. On March 22, 2016, plaintiffs filed an
amended complaint in federal court. In the amended complaint, in connection with 62 trusts governed by indenture agreements, plaintiffs assert claims for breach of contract, violation of the Trust Indenture Act, breach of fiduciary duty, and breach
of duty to



---

avoid conflicts of interest. The amended complaint alleges that the trusts at issue have suffered total realized collateral losses of U.S. $9.8 billion, but the complaint does not include a
demand for money damages in a sum certain. On July 15, 2016, DBNTC and DBTCA filed a motion to dismiss the amended complaint. On January 23, 2017, the court granted in part and denied in part DBNTC and DBTCAs motion to dismiss. The
court granted the motion to dismiss with respect to plaintiffs conflict-of-interest claim, thereby dismissing it, and denied the motion to dismiss with respect to
plaintiffs breach of contract claim (except as noted below) and claim for violation of the Trust Indenture Act, thereby allowing those claims to proceed. On January 26, 2017, the parties filed a joint stipulation and proposed order
dismissing plaintiffs claim for breach of fiduciary duty. On January 27, 2017, the court entered the parties joint stipulation and ordered that plaintiffs claim for breach of fiduciary duty be dismissed. On February 3,
2017, following a hearing concerning DBNTC and DBTCAs motion to dismiss on February 2, 2017, the court issued a short form order dismissing (i) plaintiffs representation and warranty claims as to 21 trusts whose originators
and/or sponsors had entered bankruptcy and the deadline for asserting claims against such originators and/or sponsors had passed as of 2009 and (ii) plaintiffs claims to the extent they were premised upon any alleged pre-event of default duty to terminate servicers. On March 27, 2017, DBNTC and DBTCA filed an answer to the amended complaint. On January 26, 2018, plaintiffs filed a motion for class certification. The
parties are currently briefing the motion. Discovery is ongoing.

On March 25, 2016, the BlackRock plaintiffs filed a state court action
against DBTCA in the Superior Court of California, Orange County with respect to 513 trusts. On May 18, 2016, plaintiffs filed an amended complaint with respect to 465 trusts, and included DBNTC as an additional defendant. The amended complaint
asserts three causes of action: breach of contract; breach of fiduciary duty; and breach of the duty to avoid conflicts of interest. Plaintiffs purport to bring the action on behalf of themselves and all other current owners of certificates in the
465 trusts. The amended complaint alleges that the trusts at issue have suffered total realized collateral losses of U.S. $75.7 billion, but does not include a demand for money damages in a sum certain. On August 22, 2016, DBNTC and DBTCA
filed a demurrer as to plaintiffs breach of fiduciary duty cause of action and breach of the duty to avoid conflicts of interest cause of action and motion to strike as to plaintiffs breach of contract cause of action. On
October 18, 2016, the court granted DBNTC and DBTCAs demurrer, providing plaintiffs with thirty days leave to amend, and denied DBNTC and DBTCAs motion to strike. Plaintiffs did not further amend their complaint and, on
December 19, 2016, DBNTC and DBTCA filed an answer to the amended complaint. On January 17, 2018, Plaintiffs filed a motion for class certification. The parties are currently briefing the motion. Discovery is ongoing.

On September 27, 2017, DBTCA was added as a defendant to a case brought by certain special purpose entities 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. On September 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
Trust Indenture Act; breach of contract; breach of fiduciary duty; negligence and gross negligence; violation of the 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 Trust Indenture Act claims, negligence and gross 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. Plaintiffs allege damages of hundreds of millions of dollars. On November 13, 2017, DBNTC
and DBTCA filed an answer to the third amended complaint. Discovery is ongoing.

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 the Southern 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 a defendant 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 Trust Indenture Act; breach of contract; 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 dismissed Commerzbanks Trust Indenture Act 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 on appeal. 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. Discovery is ongoing.

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 its complaint 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 Trust Indenture Act, violation of Regulation AB, and violation of
Section 9 of the Uniform Commercial 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. On January 6, 2017, IKB filed a notice of discontinuance, voluntarily dismissing with prejudice all claims as to three trusts. As of January 17, 2017, DBNTC and DBTCAs motion to dismiss has been briefed and
is awaiting decision by the court. On June 20, 2017, the parties filed a stipulation, voluntarily dismissing with prejudice all claims as to four additional trusts. Certain limited discovery is permitted to go forward while the motion to
dismiss is pending.

It is DBTCAs belief that it has no pending legal proceedings (including, based on DBTCAs present evaluation, the
litigation disclosed in the foregoing paragraphs) that would materially affect its ability to perform its duties as Trustee under the Pooling and Servicing Agreement for this transaction.

Disclosure from Wells Fargo Bank, National Association (i) as custodian under the CGCMT 2015-P1 PSA, (ii) as certificate administrator and custodian for the
Eden Roc mortgage loan under the COMM 2015-CCRE24 PSA, (iii) as certificate administrator and custodian for the Ascentia MHC Portfolio mortgage loan under the GSMS 2015-GC32 PSA and (iv) as certificate administrator and custodian for the Alderwood
Mall mortgage loan under the MSCCG 2015-ALDR TSA:

On June 18, 2014, a group of institutional investors filed a civil complaint in the Supreme Court of
the State of New York, New York County, against Wells Fargo Bank, N.A., (Wells Fargo Bank) in its capacity as trustee under 276 residential mortgage backed securities (RMBS) trusts, which was later amended on July 18, 2014,
to increase the number of trusts to 284 RMBS trusts. On November 24, 2014, the plaintiffs filed a motion to voluntarily dismiss the state court action without prejudice. That same day, a group of institutional investors filed a putative class action
complaint in the United States District Court for the Southern District of New York (the District Court) against Wells Fargo Bank, alleging claims against the bank in its capacity as trustee for 274 RMBS trusts (the Federal Court
Complaint). In December 2014, the plaintiffs motion to voluntarily dismiss their original state court action was granted. As with the prior state court action, the Federal Court Complaint is one of six similar complaints filed
contemporaneously against RMBS trustees (Deutsche Bank, Citibank, HSBC, Bank of New York Mellon and US Bank) by a group of institutional investor plaintiffs. The Federal Court Complaint against Wells Fargo Bank alleges that the trustee caused losses
to investors and asserts causes of action based upon, among other things, the trustees alleged failure to: (i) notify and enforce repurchase obligations of mortgage loan sellers for purported breaches of representations and warranties, (ii)
notify investors of alleged events of default, and (iii) abide by appropriate standards of care following alleged events of default. Relief sought includes money damages in an unspecified amount, reimbursement of expenses, and equitable relief.
Other cases alleging similar causes of action have been filed against Wells Fargo Bank and other trustees in the District Court by RMBS investors in these and other transactions, and these cases against Wells Fargo Bank are proceeding before the
same District Court judge. A similar complaint was also filed May 27, 2016 in New York state court by a different plaintiff investor. On January 19, 2016, an order was entered in connection with the Federal Court Complaint in which the District
Court declined to exercise jurisdiction over 261 trusts at issue in the Federal Court Complaint; the District Court also allowed plaintiffs to file amended complaints as to the remaining, non-dismissed trusts, if they so chose, and three amended
complaints have been filed. On December 17, 2016, the investor plaintiffs in the 261 trusts dismissed from the Federal Court Complaint filed a new complaint in New York state court (the State Court Complaint). In September 2017, Royal
Park Investments SA/NV (Royal Park), one of the plaintiffs in the District Court cases against Wells Fargo Bank, filed a putative class action complaint relating to two trusts seeking declaratory and injunctive relief and money damages
based on Wells Fargo Banks indemnification from trust funds for legal fees and expenses Wells Fargo Bank incurs or has incurred in defending the District Court case filed by Royal Park. With respect to the foregoing litigations, Wells Fargo
Bank believes plaintiffs claims are without merit and intends to contest the claims vigorously, but there can be no assurances as to the outcome of the litigations or the possible impact of the litigations on Wells Fargo Bank or the RMBS
trusts.

|8 | This annual report on Form 10-K does not include the servicer compliance statements of (i) Berkadia Commercial Mortgage LLC, as servicing function participant, (ii) Berkeley Point Capital LLC, as servicing function
participant for the Eden Roc mortgage loan under the COMM 2015-CCRE24 PSA, (iii) CWCapital Asset Management LLC, as special servicer for the Ascentia MHC Portfolio mortgage loan under the GSMS 2015-GC32 PSA, and (iv) KeyBank National Association, as
servicer and special servicer for the Alderwood Mall mortgage loan under the MSCCG 2015-ALDR TSA, because each of Berkadia Commercial Mortgage LLC, Berkeley Point Capital LLC, CWCapital Asset Management LLC and KeyBank National Association is an
unaffiliated party that services less than 10% of the pool assets of the issuing entity, and therefore is not a servicer that meets the criteria in Item 1108(a)(2)(i) through (iii) of Regulation AB.
