ITEM 1114(b)(2)

ITEM 1117
OF REGULATION AB. (LEGAL PROCEEDINGS)



The sponsor is subject to various
pending and potential legal and regulatory proceedings in the ordinary course of business, including litigation, arbitration,
claims, investigations, examinations, subpoenas and enforcement proceedings. Some litigation against the sponsor could take the
form of class actions. The outcomes of these proceedings are inherently uncertain, and thus no prediction can be confidently given
on how or when these proceedings will be resolved. An adverse outcome in one or more of these proceedings could result in substantial
damages, settlements, fines, penalties, diminished income or reputational harm to the sponsor, and could materially and adversely
affect the interest of the noteholders or the servicer’s ability to perform its duties under the transaction documents.
The proceedings identified below are those in connection with which the sponsor believes a material loss is reasonably possible
or probable.



In 2014 and 2015, General Motors
Financial Company, Inc. was served with investigative subpoenas from various state attorneys general and other governmental offices
to produce documents and data relating to its automobile loan and lease business and securitization of loans and leases. General
Motors Financial Company, Inc. believes that it has cooperated fully with all reasonable requests for information.











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
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. 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 Trustee under the Indenture for this ABS transaction.
