                                        1



The increase in consolidated net income for the three months ended March 31,
2006 compared to the same period in 2005 primarily reflects the following:

     -    Finance charge revenue increased $4.0 million (9.4%) primarily due to
          a 6.8% increase in the average size of the loan portfolio.

     -    License fees increased $0.9 million primarily due to an increase in
          the number of active dealer-partners and an increase in the monthly
          rate for CAPS fees from $499 to $599.

     -    Stock-based compensation expense decreased $0.9 million due to a
          decline in the number of unvested stock options outstanding and the
          Company's adoption of SFAS No. 123R.

Partially offsetting these improvements:

     -    Salaries and wages, as a percentage of revenue, increased to 20.2%
          from 19.0% primarily due to increased costs of information systems
          personnel.

     -    General and administrative expenses, as a percentage of revenue,
          increased to 12.8% from 11.6% primarily due to additional professional
          fees associated with the restatement and an increase in corporate
          legal expenses.

     -    Sales and marketing expenses, as a percentage of revenue, increased to
          8.2% from 7.4% primarily due to an increase in dealer support products
          and sales promotions.

     consumer loan unit volume from dealer-partners who submitted at least one
     consumer loan during the comparable period of the prior year but who
     submitted no consumer loans during the current period divided by prior year
     comparable period consumer loan unit volume.

COMPARISON OF GAAP RETURN ON CAPITAL TO FLOATING YIELD RETURN ON CAPITAL

The following table presents selected financial data that compares the Company's
GAAP basis financial results to a non-GAAP measure. The Company's finance charge
revenue is based on estimates of future cash flows. Under GAAP, favorable
changes in expected cash flows are treated as yield adjustments, while
unfavorable changes are recorded as a current period expense. The non-GAAP
measure ("Floating-Yield") is identical to the Company's GAAP basis results
except that, under the Floating Yield method, all changes in expected cash flows
are treated as yield adjustments and therefore impact earnings over time. The
GAAP treatment always results in a lower carrying value of the loan receivable
asset, but may result in either higher or lower earnings for any given period
depending on the timing and amount of expected cash flow changes.

CAUTIONARY STATEMENT REGARDING FORWARD LOOKING INFORMATION

The Company claims the protection of the safe harbor for forward-looking
statements contained in the Private Securities Litigation Reform Act of 1995 for
all of its forward-looking statements. These forward-looking statements
represent the Company's outlook only as of the date of this report. While the
Company believes that its forward-looking statements are reasonable, actual
results could differ materially since the statements are based on our current
expectations, which are subject to risks and uncertainties. Factors that might
cause such a difference include, but are not limited to, the factors set forth
in Item 1A of the Company's Form 10-K for the year ended December 31, 2005,
other risk factors discussed herein or listed from time to time in the Company's
reports filed with the Securities and Exchange Commission and the following:

     -    The Company's inability to accurately forecast and estimate the amount
          and timing of future collections could have a material adverse effect
          on results of operations.

     -    Due to increased competition from traditional financing sources and
          non-traditional lenders, the Company may not be able to compete
          successfully.

     -    The Company's ability to maintain and grow the business is dependent
          on the ability to continue to access funding sources and obtain
          capital on favorable terms.

     -    The Company may not be able to generate sufficient cash flow to
          service its outstanding debt and fund operations.

     -    The substantial regulation to which the Company is subject limits the
          business, and such regulation or changes in such regulation could
          result in potential liability.

     -    Adverse changes in economic conditions, or in the automobile or
          finance industries or the non-prime consumer finance market, could
          adversely affect the Company's financial position, liquidity and
          results of operations and its ability to enter into future financing
          transactions.

     -    Litigation the Company is involved in from time to time may adversely
          affect its financial condition, results of operations and cash flows.

     -    The Company is dependent on its senior management and the loss of any
          of these individuals or an inability to hire additional personnel
          could adversely affect its ability to operate profitably.

     -    Natural disasters, acts of war, terrorist attacks and threats or the
          escalation of military activity in response to such attacks or
          otherwise may negatively affect the business, financial condition and
          results of operations.

Other factors not currently anticipated by management may also materially and
adversely affect the Company's results of operations. The Company does not
undertake, and expressly disclaims any obligation, to update or alter its
statements whether as a result of new information, future events or otherwise,
except as required by applicable law.

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 from sales of vehicles to consumers who otherwise
could not obtain financing; from 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 may be unable to purchase a vehicle or they may
purchase an unreliable one, or they may not have 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 under the symbol CACC. For more

ECONOMIC PROFIT

The Company defines economic profit as net income less an imputed cost of
equity. Economic profit measures how efficiently the Company utilizes its
capital. To consider the cost of both debt and equity, the Company's calculation
of economic profit deducts from net income a cost of equity equal to 10% of
average equity, which approximates the S&P 500's rate of return since 1965.
Management uses economic profit to assess the Company's performance as well as
to make capital allocation decisions. Management believes this information is
important to shareholders because it allows shareholders to compare the returns
earned by the Company with the return they could expect if the Company returned
capital to shareholders and they invested in other securities.
