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)



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 DERIVATIVES 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 INFORMATION (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 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.



In the ordinary course of business, The Bank of New York Mellon is named as a defendant in or made a party
to pending and potential legal actions. In connection with its role as trustee of certain residential mortgage-backed securitization,
or RMBS, transactions, The Bank of New York Mellon has been named as a defendant in a number of legal actions brought by RMBS investors.
These lawsuits allege that the trustee had expansive duties under the governing agreements, including the duty to investigate and
pursue breach of representation and warranty claims against other parties to the RMBS transactions. While it is inherently difficult
to predict the eventual outcomes of pending actions, The Bank of New York Mellon denies liability and intends to defend the litigations
vigorously.











ITEM 1119
OF REGULATION AB. (AFFILIATIONS AND CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS)



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