ADDITIONAL DISCLOSURE ITEMS REQUIRED BY GENERAL INSTRUCTION J(2)

Item 1112(b) of Regulation AB

The property securing
the 135 South LaSalle mortgage loan constitutes a significant obligor within the meaning of Item 1101(k)(2) of Regulation AB and as disclosed in the Prospectus Supplement for Citigroup Commercial Mortgage Trust 2015-GC31 filed on July 8,
2015. With respect to the property securing the 135 South LaSalle mortgage loan, the most recent unaudited net operating income was $18,130,257 from January 1, 2015 through December 31, 2015.

Item 1114(b)(2) and Item 1115(b) of Regulation AB

No entity or group of affiliated entities provides any external credit enhancement, uses any derivative instruments or other support for the certificates
within this transaction.

Item 1117 of Regulation AB

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

On
June 18, 2014, a civil action was filed against Citibank, N.A. (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, 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. Citibanks motion to dismiss the federal complaint was fully briefed as of May 13, 2015. 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. That case, involving the three remaining trusts, is pending.

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. Citibank
filed a motion to dismiss this case on February 26, 2016.

On August 19, 2015, the Federal Deposit Insurance Corporation (FDIC) as Receiver for
a 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 is jointly briefing a motion to dismiss with The Bank of New York Mellon and U.S. Bank, entities that have also been sued by FDIC in their capacity as trustee,
and whose cases are all in front of Judge Carter. Defendants joint motion to dismiss was fully briefed as of March 22, 2016.

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:

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 Deutsche Bank Trust Company Americas (DBTCA) and Deutsche Bank National Trust Company (DBNTC) 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 (TIA), 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 as to the 64 trusts formed under indentures for which it retained jurisdiction. Instead, the court ordered plaintiffs to file
an amended complaint as to those indenture trusts. On February 23, 2016, plaintiffs filed an amended complaint as to 62 of the 64 indenture trusts included in the original U.S. District Court complaint. DBNTC and DBTCA will have an opportunity to
file new defensive motions with respect to this amended complaint.

On March 25, 2016, plaintiffs filed a new state court complaint in California against
DBTCA as to 513 trusts governed by Pooling and Servicing Agreements, most of which had been dismissed from the U.S. District Court action. (Plaintiffs removed 19 of the original 500 and have added 32 new trusts.) DBTCA serves as trustee on only one
of these 513 trusts.

On December 30, 2015, IKB International, S.A. and IKB Deutsche Industriebank A.G. filed a Summons With Notice in New York state
court naming as defendants DBNTC and DBTCA, as trustees of 37 RMBS trusts (the IKB Action). The claims in the IKB Action appear to be substantively similar to the SDNY Action. The IKB Action is not styled as a putative class action, but
may attempt to bring derivative claims on behalf of the named RMBS Trusts. DBTCA intends to vigorously defend the IKB Action.

DBTCA 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.
