DESCRIPTION OF CREDIT ACCEPTANCE CORPORATION Since 1972, Credit Acceptance has provided auto loans to consumers, regardless of their credit history. Our product is offered through a nationwide network of automobile dealers who benefit by selling vehicles to consumers who otherwise could not obtain financing, by repeat and referral sales generated by these same customers, and from sales to customers responding to advertisements for our product, but who actually end up qualifying for traditional financing. Without our product, consumers are often unable to purchase a vehicle or they purchase an unreliable one and are not provided the opportunity to improve their credit standing. As we report to the three national credit reporting agencies, a significant number of our customers improve their lives by improving their credit score and move on to more traditional sources of financing. Credit Acceptance is publicly traded on the NASDAQ National Market under the symbol CACC. For more information, visit www.creditacceptance.com.
