- TABLE FOLLOWS -

Non-GAAP Financial Measures

The non-GAAP financial measures contained herein are a supplement to the corresponding financial measures prepared in accordance with generally accepted accounting principles (GAAP). The non-GAAP financial measures presented exclude the items summarized in the below table. Management believes that adjustments for these items assist investors in making comparisons of period-to-period operating results and that these items are not indicative of the Company’s on-going core operating performance.

Management uses non-GAAP net income per diluted share in its evaluation of the Company’s core after-tax results of operations and trends between fiscal periods and believes that these measures are important components of its internal performance measurement process. Management believes that providing these non-GAAP financial measures allows investors to view the Company’s financial results in the way that management views the financial results.

The non-GAAP financial measures presented herein have certain limitations in that they do not reflect all of the costs associated with the operations of the Company’s business as determined in accordance with GAAP. Therefore, investors should consider non-GAAP financial measures in addition to, and not as a substitute for, or as superior to, measures of financial performance prepared in accordance with GAAP. The non-GAAP financial measures presented by the Company may be different from the non-GAAP financial measures used by other companies.
