Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

On March 5, 2012, Asset Acceptance Capital Corp. issued a press release announcing its results of operations and financial condition as of and for the quarter and fiscal year ended December 31, 2011, unaudited. The press release is being furnished pursuant to Item 2.02 of Form 8-K. The full text of the press release is furnished as Exhibit 99.1 to this Form 8-K and is incorporated in this report by reference.

The press release attached to this Form 8-K contains a financial measure for Adjusted EBITDA that is not calculated in accordance with accounting principles generally accepted in the United States of America (“GAAP”). We have provided a reconciliation in the press release of the non-GAAP financial measure for Adjusted EBITDA to GAAP net income.

We have included information concerning Adjusted EBITDA because we believe that this financial measure provides important supplemental information to management and investors. We use Adjusted EBITDA for planning purposes, including the preparation of internal budgets and forecasts, in communications with the Board of Directors, stockholders, analysts and investors concerning our financial performance, and as a key component in management’s annual incentive compensation plan. Adjusted EBITDA is also used as a measure of operating performance for the financial covenants in our credit agreement. This non-GAAP financial measure should not be considered an alternative to, or more meaningful than, net income prepared on a GAAP basis.

The press release also contains references that eliminate the impact of certain operating expenses, extinguishment of debt, restructuring charges and the related tax effects of these items, incurred during the quarter and fiscal year ended December 31, 2011 and 2010 from net income or loss and contains a reconciliation of these items to net income or loss in accordance with GAAP. These charges are not considered non-recurring, infrequent or unusual. However, we believe this information is useful to identify net income or loss for the quarter and fiscal year ended December 31, 2011 and 2010 excluding the impact of these items.

In addition, the press release contains a table that identifies the components of purchased receivables revenue, and identifies a metric referred to as core amortization. Core amortization is a financial ratio that excludes certain collections from the calculated amortization rate. Management uses this ratio to identify over or under performance compared to forecast for portfolios with remaining balances.

The following exhibits are furnished herewith:
