The following supplemental tables provide non-GAAP financial measures used by the company's management to evaluate operational results. The company believes this information may be useful to investors. In addition to disclosing financial results calculated in accordance with U.S. generally accepted accounting principles (GAAP), the company's earnings release contains non-GAAP financial measures that exclude the income statement effects of share-based compensation, amortization of purchase product rights and other purchased intangibles, and non recurring restructuring and impairment charges. The non-GAAP financial measures disclosed by the company should not be considered a substitute for, or superior to, financial measures calculated in accordance with GAAP, and the financial results calculated in accordance with GAAP and reconciliations to those financial statements should be carefully evaluated. The non-GAAP financial measures used by the company may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies.

Set forth below are reconciliations of the non-GAAP financial measures to the most directly comparable GAAP financial measures.

For additional information regarding these non-GAAP financial measures, see the Form 8-K dated April 22, 2008 that Entrust has filed with the Securities and Exchange Commission.
