Guarantees [Abstract]
Guarantees	Note G—Guarantees The Company guarantees the borrowings of certain independently controlled automotive parts stores (“independents”) and certain other affiliates in which the Company has a noncontrolling equity ownership interest (“affiliates”). Presently, the independents are generally consolidated by unaffiliated enterprises that have a controlling financial interest through ownership of a majority voting interest in the entity. The Company has no voting interest or direct or indirect equity ownership interest in any of the independents. The Company does not control the independents or the affiliates but receives a fee for the guarantee. The Company has concluded that the independents are variable interest entities but that the Company is not the primary beneficiary. Specifically, the equity holders of the independents have the power to direct the activities that most significantly impact the entity’s economic performance including, but not limited to, decisions about hiring and terminating personnel, local marketing and promotional initiatives, pricing and selling activities, credit decisions, monitoring and maintaining appropriate inventories, and store hours. Separately, the Company concluded the affiliates are not variable interest entities. The Company’s maximum exposure to loss as a result of its involvement with these independents and affiliates is equal to the total borrowings subject to the Company’s guarantee. While such borrowings of the independents and affiliates are outstanding, the Company is required to maintain compliance with certain covenants, including a maximum debt to capitalization ratio and certain limitations on additional borrowings. At March 31, 2012, the Company was in compliance with all such covenants. At March 31, 2012, the total borrowings of the independents and affiliates subject to guarantee by the Company were approximately $216.1 million. These loans generally mature over periods from one to six years. In the event that the Company is required to make payments in connection with guaranteed obligations of the independents or the affiliates, the Company would obtain and liquidate certain collateral (e.g., accounts receivable and inventory) to recover all or a portion of the amounts paid under the guarantee. When it is deemed probable that the Company will incur a loss in connection with a guarantee, a liability is recorded equal to this estimated loss. To date, the Company has had no significant losses in connection with guarantees of independents’ and affiliates’ borrowings. The Company has accrued for certain guarantees related to the independents’ and affiliates’ borrowings as of March 31, 2012. These liabilities are not material to the financial position of the Company and are included in “Other long-term liabilities” in the accompanying condensed consolidated balance sheets.
