Guarantees [Abstract]
Guarantees	Guarantees The Company guarantees the borrowings of certain independently controlled automotive parts stores and businesses (“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 controlling financial interests through ownership of a majority voting interest in the independents. The Company has no voting interest or equity conversion rights in any of the independents. The Company does not control the independents or the affiliates but receives a fee for the guarantees. 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 entities’ 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 that 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 generally equal to the total borrowings subject to the Company’s guarantees. While such borrowings of the independents and affiliates are outstanding, the Company is required to maintain compliance with certain covenants. At June 30, 2021, the Company was in compliance with all such covenants. As of June 30, 2021, the total borrowings of the independents and affiliates subject to guarantee by the Company were approximately $896,080. These loans generally mature over periods from one to six years. The Company regularly monitors the performance of these loans and the ongoing operating results, financial condition and ratings from credit rating agencies of the independents and affiliates that participate in the guarantee programs. In the event that the Company is required to make payments in connection with these guarantees, the Company would obtain and liquidate certain collateral pledged by the independents or affiliates (e.g., accounts receivable and inventory) to recover all or a substantial portion of the amounts paid under the guarantees. The Company recognizes a liability equal to current expected credit losses over the lives of the loans in the guaranteed loan portfolio, based on a consideration of historical experience, current conditions, the nature and expected value of any collateral, and reasonable and supportable forecasts. To date, the Company has had no significant losses in connection with guarantees of independents’ and affiliates’ borrowings and the current expected credit loss reserve is not material. As of June 30, 2021, there are no material guaranteed loans for which the borrower is experiencing financial difficulty and recovery is expected to be provided substantially through the operation or sale of the collateral. As of June 30, 2021, the Company has recognized certain assets and liabilities amounting to $78,000 each for the guarantees related to the independents’ and affiliates’ borrowings. These assets and liabilities are included in other assets and other long-term liabilities in the condensed consolidated balance sheets. The liabilities relate to the Company's noncontingent obligation to stand ready to perform under the guarantee programs and they are distinct from the Company's current expected credit loss reserve.
