Non-GAAP Financial Measures

This press release and accompanying table contain certain non-GAAP financial measures including non-GAAP gross profit, non-GAAP gross margin, non-GAAP income from operations, non-GAAP operating margins, non-GAAP net income and non-GAAP diluted net income per share. These non-GAAP financial measures exclude stock-based compensation expense, amortization of acquisition-related intangible assets, certain non-recurring charges or benefits, and the income tax effect of these non-GAAP exclusions. In addition, non-GAAP financial measures exclude net tax benefits associated with stock-based awards, which include excess tax benefits, and other discrete indirect effects of such awards. The company uses these non-GAAP financial measures internally in analyzing its financial results and believes that these non-GAAP financial measures are useful to investors as an additional tool to evaluate ongoing operating results and trends. In addition, these measures are the primary indicators management uses as a basis for its planning and forecasting for future periods.

Non-GAAP financial measures are not meant to be considered in isolation or as a substitute for the comparable GAAP financial measures. Non-GAAP financial measures are subject to limitations, and should be read only in conjunction with the company's consolidated financial statements prepared in accordance with GAAP. Non-GAAP financial measures do not have any standardized meaning and are therefore unlikely to be comparable to similarly titled measures presented by other companies. A description of these non-GAAP financial measures and a reconciliation of the company’s non-GAAP financial measures to their most directly comparable GAAP measures have been provided in the financial statement tables included in this press release, and investors are encouraged to review the reconciliation.

The company’s guidance for non-GAAP financial measures excludes stock-based compensation expense, amortization of acquisition-related intangible assets, and other non-recurring items. The company does not provide guidance on GAAP gross margin or GAAP operating margin or the various reconciling items between GAAP gross margin and GAAP operating margin and non-GAAP gross margin and non-GAAP operating margin. A reconciliation of the non-GAAP financial measures guidance to the corresponding GAAP measures on a forward-looking basis is not available because stock-based compensation expense is impacted by the company’s future hiring and retention needs and the future fair market value of the company’s common stock, all of which are difficult to predict and subject to constant change. The actual amount of stock-based compensation expense will have a significant impact on the company’s GAAP gross margin and GAAP operating margin.
