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 Trust Indenture Act of 1939 (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 March 22, 2018, the court granted Citibanks motion
for 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 on
August 3, 2018. Citibank filed its opposition on November 2, 2018. Plaintiffs filed their reply on November 16, 2018. 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 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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. Defendants jointly filed a motion to dismiss the amended complaint on
March 13, 2018. On April 18, 2018, plaintiff filed its opposition. Defendants filed their joint reply on May 3, 2018. 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 Wells Fargo Bank, National Association, as certificate administrator and as custodian for the General Motors Building
mortgage loan under the BXP 2017-GM TSA, the Olympic Tower mortgage loan under the Olympic Tower 2017-OT TSA, the 245 Park Avenue mortgage loan under the 245 Park Avenue
Trust 2017-245P TSA, the Starwood Capital Group Hotel Portfolio mortgage loan under the DBJPM 2017-C6 PSA and the Gurnee Mills mortgage loan under the CSAIL 2016-C7 PSA: Since June 18, 2014, a group of institutional investors have 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 of New York against Wells Fargo Bank, N.A., (Wells Fargo Bank) in its capacity as trustee for certain residential mortgage backed securities (RMBS) trusts. The
complaints against Wells Fargo Bank alleged that the trustee caused losses to investors and asserted 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 included money damages in
an unspecified amount, reimbursement of expenses, and equitable relief. Wells Fargo Bank has reached an agreement, in which it denies any wrongdoing, to resolve these claims on a classwide basis for the 271 RMBS trusts currently at issue. The
settlement agreement is subject to court approval. Separate lawsuits against Wells Fargo Bank making similar allegations filed by certain other institutional investors concerning 57 RMBS trusts in New York federal and state court are not covered by
the agreement. 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. Item 1119 of Regulation AB Provided previously in the prospectus of the Registrant relating to the issuing entity and filed on August 15, 2017 pursuant to Rule 424(b)(2) of the
