1 Statement on Use of Non-GAAP Financial Measures:To supplement its condensed consolidated financial statements presented in accordance with accounting principles generally accepted in the United States (“GAAP”), the Company discloses certain non-GAAP financial measures, including “non-GAAP net income”, “net income on a non-GAAP basis”, “non-GAAP net income per share”, “non-GAAP EPS” and “net income per share on a non-GAAP basis”. These non-GAAP financial measures are not presented in accordance with GAAP and are not meant to be a substitute for the most directly comparable GAAP measures of “net income”, “EPS” or “net income per share”. Rather, these non-GAAP financial measures should be evaluated in conjunction with its most directly comparable GAAP financial measure and the Company’s financial statements as a whole. Management uses these supplemental non-GAAP financial measures to evaluate performance period over period, to analyze the underlying trends in the Company's business, to assess its performance relative to its competitors, and to establish operational goals and forecasts that are used in allocating resources. Management uses these non-GAAP financial measures because they exclude stock-based compensation expense which is a non-cash charge and related payroll taxes, as well as amortization of acquired intangible assets and merger and integration-related costs associated with the Company’s acquisition activities, all of which are non-operational costs and expenses. By excluding stock-based compensation expense and related payroll taxes, amortization of acquired intangible assets, and merger and integration-related costs, management can compare the Company’s operations to prior periods and to the operations of other companies in its industry who may have materially different unusual, non-operational charges. Management does not consider any of stock-based compensation expense and related payroll taxes, amortization of acquired intangible assets, and merger and integration-related costs to be part of the Company’s operating activities or meaningful in evaluating the Company’s past financial performance or future prospects. Management believes that excluding these items is useful to investors because it is more representative of ongoing costs and therefore more comparable to historical operations.
