vehicles, manufacturer floor plan interest and advertising assistance, and warranties on new and used vehicles. A discontinuation of or change to the manufacturers’ incentive programs may adversely impact vehicle demand, the value of new and used vehicles, and may materially affect our results of operations.
Our business is very competitive. We generally compete with: other franchised dealerships in our markets; private market buyers and sellers of used vehicles; Internet-based vehicle brokers; national and local service and repair shops and parts retailers; with respect to commercial vehicles, distributors of similar products; and manufacturers in certain markets. Purchase decisions by consumers when shopping for a vehicle are extremely price sensitive. The level of competition in the market generally, coupled with increasing price transparency resulting from increased use of the Internet by consumers, and pricing discounts to customers, can lead to lower selling prices and related profits. If there is a prolonged drop in retail prices, new vehicle sales are allowed to be made over the Internet without the involvement of franchised dealers, or if dealerships are able to effectively use the Internet to sell outside of their markets, our business could be materially adversely affected.
Evolving automotive and trucking industries. The automotive and trucking industries are predicted to experience rapid change. Shared vehicle services such as Uber and Lyft provide consumers with increased choice in their personal mobility options. The effect of these and similar mobility options on the retail automotive industry is uncertain, and may include lower levels of new vehicles sales, but with increasing miles driven, which could require additional demand for vehicle maintenance. In addition, technological advances are facilitating the development of driverless vehicles. The eventual timing of availability of driverless vehicles is uncertain due to regulatory requirements, additional technological requirements, and uncertain consumer acceptance of these vehicles. The effect of driverless vehicles on the automotive retail and trucking industries is uncertain and could include changes in the level of new and used vehicles sales, the price of new vehicles, and the role of franchised dealers, any of which could materially and adversely affect our business.
Property loss, business interruption or other liabilities. Our business is subject to substantial risk of loss due to: the significant concentration of property values, including vehicle and parts inventories, at our operating locations; claims by employees, customers and third parties for personal injury or property damage; and fines and penalties in connection with alleged violations of regulatory requirements. While we have insurance for many of these risks, we retain risk relating to certain of these perils and certain perils are not covered by our insurance. Certain insurers have limited available property coverage in response to the natural catastrophes experienced in recent years. If we experience significant losses that are not covered by our insurance, whether due to adverse weather conditions or otherwise, or we are required to retain a significant portion of a loss, it could have a significant and adverse effect on us.
Leverage. Our significant debt and other commitments expose us to a number of risks, including:
Cash requirements for debt and lease obligations. A significant portion of the cash flow we generate must be used to service the interest and principal payments relating to our various financial commitments, including $3.3 billion of floor plan notes payable, $1.9 billion of non-vehicle long-term debt and $4.5 billion of future lease commitments (including extension periods that are reasonably assured of being exercised and assuming constant consumer price indices). A sustained or significant decrease in our operating cash flows could lead to an inability to meet our debt service or lease requirements or to a failure to meet specified financial and operating covenants included in certain of our agreements. If this were to occur, it may lead to a default under one or more of our commitments and potentially the acceleration of amounts due, which could have a significant and adverse effect on us.
Availability. Because we finance the majority of our operating and strategic initiatives using a variety of commitments, including floor plan notes payable and revolving credit facilities, we are dependent on continued availability of these sources of funds. If these agreements are terminated or we are unable to access them because of a breach of financial or operating covenants or otherwise, we will likely be materially affected.
Interest rate variability. The interest rates we are charged on a substantial portion of our debt, including the floor plan notes payable we issue to purchase the majority of our inventory, are variable, increasing or decreasing based on changes in certain published interest rates. Increases to such interest rates would likely result in significantly higher interest expense for us, which would negatively affect our operating results. Because many of our customers finance their
