On November 2, 2011, American Reprographics Company (the “Company”) issued a press release reporting its financial results for the third quarter of 2011. A copy of the press release is furnished as Exhibit 99.1.

The information contained in Item 2.02 of this Current Report on Form 8-K, including Exhibit 99.1 attached hereto, shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or incorporated by reference into any filing of the Company under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.

The Company monitors the recovery of goodwill recorded in connection with acquisitions annually as of September 30 and on an interim basis if events or changes in circumstances indicate that the carrying amount may not be recoverable. On October 31, 2011, in connection with its annual goodwill impairment analysis under Accounting Standards Codification 350 (formerly Statement of Financial Accounting Standards No. 142), the Company determined that a goodwill impairment charge for the third quarter of fiscal year 2011 in the amount of $42.1 million was required. The main factor leading to the conclusion that a goodwill impairment charge was required was an increase in the Company’s reporting units’ weighted average cost of capital (WACC). This change in WACC was due, in part, to (i) uncertainty in timing of recovery in the construction industry, (ii) increased uncertainty in the overall economy, (iii) a significant decline in the price of the Company’s high yield notes (resulting in a significantly higher yield) during the third quarter of fiscal year 2011, and (iv) the significant decline of the Company’s stock price in the third quarter of fiscal year 2011. The Company will not be required to make any current or future cash expenditures as a result of the impairment. The impairment charge will be reflected in the Company’s unaudited financial statements as of and for the third quarter ended September 30, 2011.
