Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant

On October 17, 2014, General Motors Financial Company, Inc. (“GM Financial”), General Motors Company (“GM”) and certain wholly-owned subsidiaries of GM amended and restated two existing revolving credit facilities (together the “Facilities”) to increase aggregate borrowing capacity to $12.5 billion with JPMorgan Chase Bank, N.A., as the administrative agent, Citibank, N.A., as syndication agent, and a syndicate of 40 lenders. These Facilities amend and restate the three year, $5.5 billion revolving credit facility that GM, GM Financial and certain wholly-owned subsidiaries of GM entered into in November 2012 and the five year, $5.5 billion revolving credit facility that GM and certain wholly-owned subsidiaries of GM entered into in November 2012. The Facilities consist of a three year, $5.0 billion facility and a five year, $7.5 billion facility. These Facilities are unsecured and provide additional liquidity and improved terms.

The three year, $5.0 billion facility is available to GM, GM Financial and certain other wholly-owned subsidiaries of GM. The facility allows for borrowing in U.S. Dollars and other currencies and includes a GM Financial borrowing sub-limit of $2.0 billion. The five year, $7.5 billion facility is available to GM, GM Financial and certain other wholly-owned subsidiaries of GM. The facility allows for borrowings in U.S. Dollars and other currencies and includes a GM Financial borrowing sub-limit of $2.0 billion.

Additionally, subject to compliance with certain covenants, GM can further upsize the Facilities.

GM has guaranteed the obligations of subsidiary borrowers, including GM Financial, under the Facilities. If GM fails to maintain an investment grade corporate rating from two or more of the following credit rating agencies: Fitch Ratings, Moody’s Investor Service and Standard & Poor’s, GM will be required to provide guarantees from certain domestic subsidiaries (other than GM Financial) under the terms of the Facilities.

Interest rates on obligations under the Facilities are based on prevailing annual interest rates for Eurodollar loans or an alternative base rate, both subject to an applicable margin. This applicable margin will be based upon the credit rating assigned to the Facilities.

The Facilities contain representations, warranties and covenants that are typical for these types of facilities. These covenants include restrictions on mergers or sales of assets and secured debt borrowings, subject to exceptions and limitations. The Facilities also require GM to maintain at least $4.0 billion in global liquidity and at least $2.0 billion in U.S. liquidity.

Some of the lenders under the Facilities and their affiliates have various relationships with GM Financial and its subsidiaries involving the provision of financial services, including cash management and investment banking services. In addition, GM Financial, through its subsidiaries, may enter into derivative arrangements with certain of the lenders and their affiliates.

The foregoing description does not constitute a complete summary of the Facilities and is qualified by reference in its entirety to the full text of the Facilities filed herewith.
