ITEM 1.01 Entry into a Material Definitive Agreement

On August 13, 2012, General Motors Financial Company, Inc. (the “Company”) issued and sold $1,000,000,000 in aggregate principal amount of 4.750% Senior Notes due 2017 (the “Notes”). The Company offered and sold the Notes to the initial purchasers in reliance on the exemption from registration provided by Section 4(2) of the Securities Act of 1933, as amended (the “Securities Act”). The initial purchasers then resold the Notes pursuant to the exemptions from registration under the Securities Act, including Rule 144A and Regulation S. The Company relied on these exemptions from registration based in part on representations made by the initial purchasers in the purchase agreement relating to the issuance and sale of the Notes.

The Notes are governed by an Indenture (the “Indenture”), dated August 16, 2012, between the Company, AmeriCredit Financial Services, Inc., the guarantor, and Wells Fargo Bank, N.A., as trustee.

The Notes will bear interest at a rate of 4.750% per year on the principal amount of the Notes, payable semi-annually in arrears on February 15 and August 15 of each year, beginning on February 15, 2013. The Notes will mature on August 15, 2017. The Indenture contains covenants that, among other things, limit the Company’s and certain of its subsidiaries’ ability to sell all or substantially all of their assets or merge or consolidate with or into other companies and incur liens.

The Notes are redeemable at the Company’s option, in whole or in part, at any time at the redemption prices specified in the Indenture, plus accrued and unpaid interest and liquidated damages, if any, to the redemption date. In addition, if a change of control occurs, as that term is defined in the Indenture, prior to the Company being rated “investment grade” by at least two of three listed rating agencies, the holders of Notes will have the right, subject to certain conditions, to require the Company to repurchase their Notes at a purchase price equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest and liquidated damages, if any, as of the date of repurchase.

The Indenture provides for customary events of default, including nonpayment, failure to comply with covenants or other agreements in the Indenture, any subsidiary guarantee shall cease to be in full force and effect or any guarantor shall deny or disaffirm its obligations under its subsidiary guarantee, and certain events of bankruptcy or insolvency. If any event of default occurs and is continuing, the trustee or the holders of at least 25% in principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately.

The Company agreed, pursuant to a registration rights agreement with the initial purchasers (the “Registration Rights Agreement”), to use commercially reasonable efforts to issue in exchange for the Notes, on or prior to the 365^th day following the closing date of the issuance and sale of the Notes, identical new notes registered under the Securities Act. In certain circumstances, the Company may be required to file a shelf registration statement to cover resales of the Notes. If the Company does not comply with certain covenants set forth in the Registration Rights Agreement, it must pay liquidated damages to holders of the Notes.

The descriptions set forth above are qualified in their entirety by the Indenture and the Registration Rights Agreement filed as exhibits hereto.

On August 13, 2012, the Company issued a press release announcing the pricing of its private offering of $1,000,000,000 of its 4.750% Senior Notes due 2017 to certain qualified institutional buyers pursuant to Rule 144A and in accordance with Regulation S. A copy of the press release is attached as Exhibit 99.1 to this Current Report on Form 8-K.

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

The information set forth in Item 1.01 above is incorporated by reference into this Item 2.03.
