None.



SUBSTITUTE INFORMATION INCLUDED
IN ACCORDANCE WITH GENERAL INSTRUCTION J TO FORM 10-K:



ITEM 1112(b) OF REGULATION AB. SIGNIFICANT
OBLIGORS OF POOL ASSETS (FINANCIAL INFORMATION)



There is no single obligor that represents
more than 10% of the pool assets.



ITEM 1114(b)(2) OF REGULATION AB. CREDIT
ENHANCEMENT AND OTHER SUPPORT, EXCEPT FOR CERTAIN DERIVATIVE INSTRUMENTS (FINANCIAL INFORMATION)



There is no external credit enhancement
or other support provider that is liable to provide payments supporting any notes or certificates issued by the Issuing Entity.



ITEM 1115(b) OF REGULATION AB. CERTAIN
DERIVATIVE INSTRUMENTS (FINANCIAL INFORMATION)



No entity provides any derivative instruments
that are used to alter the payment characteristics of the cash flows from the Issuing Entity.



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 the sponsor cannot confidently predict 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.



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, or 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. On May 6, 2019, the court entered an order approving the settlement agreement. 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. AFFILIATIONS
AND CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

AB has been omitted from this report on Form 10-K in reliance on the Instruction to Item 1119.
