Risks and Uncertainties [Abstract] |
Business And Credit Concentrations | BUSINESS AND CREDIT CONCENTRATIONS We are subject to a concentration of risk in the event of financial distress of or other adverse event related to a major vehicle manufacturer or related lender or supplier. The core brands of vehicles that we sell, representing approximately 93% of the new vehicles sold during the three months ended March 31, 2017, are manufactured by Toyota (including Lexus), Ford, Honda, General Motors, FCA US, Mercedes-Benz, Nissan, BMW, and Volkswagen (including Audi and Porsche). Our business could be materially adversely impacted by a bankruptcy of or other adverse event related to a major vehicle manufacturer or related lender or supplier. We had receivables from manufacturers or distributors of $203.6 million at March 31, 2017, and $234.9 million at December 31, 2016. Additionally, a large portion of our Contracts-in-Transit included in Receivables, Net, in the accompanying Unaudited Condensed Consolidated Balance Sheets, are due from automotive manufacturers’ captive finance subsidiaries, which provide financing directly to our new and used vehicle customers. Concentrations of credit risk with respect to non-manufacturer trade receivables are limited due to the wide variety of customers and markets in which our products are sold as well as their dispersion across many different geographic areas in the United States. Consequently, at March 31, 2017, we do not consider AutoNation to have any significant non-manufacturer concentrations of credit risk.
