|ITEM 16. | FORM 10-K SUMMARY
|-------- | -----------------

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.

ITEM 1122 OF REGULATION AB. COMPLIANCE WITH APPLICABLE SERVICING CRITERIA.

The following documents are filed as part of this report.
