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 KeyBank National Association, as
special servicer for the Pleasant Prairie Premium Outlets mortgage loan and the Corporate Woods Portfolio mortgage loan under the CGCMT 2017-P8 PSA (as defined in Item 15(a)(3) below):

On February 23, 2016, a certificateholder of the J.P. Morgan Chase Commercial Mortgage Securities Trust, Series 2007-CIBC18 (the Trust) filed suit
in the Supreme Court of New York, County of New York, against KeyBank National Association and Berkadia Commercial Mortgage LLC (collectively, the Servicers). The suit was filed derivatively on behalf of the Trust. The action
was brought in connection with the Servicers determination of the fair value of a loan, secured by the Bryant Park Hotel in New York City, held by the Trust and sold to an assignee of the Trusts directing certificateholder, pursuant to
an exercise of the fair value option set forth in the Pooling and Servicing Agreement governing the Trust. There can be no assurances as to the outcome of the action or the possible impact of the litigation on the Servicers. Both Servicers
deny liability, believe that they performed their obligations in accordance with the terms of the Pooling and Servicing Agreement, and have contested the claims asserted against them, filing a motion to dismiss the case. On November 28, 2016,
the Servicers motion to dismiss was granted. The plaintiff certificateholder has filed a notice of appeal, and the appeal is pending.

|8 | This annual report on Form 10-K does not include the servicer compliance statement of KeyBank National Association, as special servicer for the Pleasant Prairie Premium Outlets mortgage loan and the Corporate Woods
Portfolio mortgage loan under the CGCMT 2017-P8 PSA, because 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.
