The Company's press release dated April 27, 2006 announcing the results for the first quarter 2006 is attached hereto as Exhibit 99.1. The press release presented non-GAAP financial information, such as EBITDA (earnings before interest, taxes, depreciation and amortization), which is not a measure of financial performance under generally accepted accounting principles. The Company believes EBITDA is useful supplemental information for investors to evaluate financial performance. This data is also used by the Company for assessment of its operating and financial results, in addition to operating income, net income and other GAAP measures. Management believes EBITDA is a useful indicator of the Company's financial and operating performance and its ability to generate cash flows from operations that are available for taxes and capital expenditures. Investors should recognize that EBITDA might not be comparable to similarly-titled measures of other companies. This measure should be considered in addition to, and not as a substitute for or superior to, any measure of performance prepared in accordance with accounting principles generally accepted in the United States. Item 9.01 Financial Statements and Exhibits 99.1 Press Release dated April 27, 2006. SIGNATURES Pursuant to the requirements of section 13 or 15(d) of the Securities Exchange Act of 1934, the Registrant has duly caused this report to be signed on its behalf by the undersigned, thereunto duly authorized.
