Non-GAAP Financial Measures

To supplement our condensed consolidated financial statements, which are presented on a GAAP basis, we disclose revenue on a constant currency basis, non-GAAP income from operations, non-GAAP net income, non-GAAP net income per diluted share and Adjusted EBITDA. These non-GAAP measures are not in accordance with, or an alternative for, amounts determined in accordance with generally accepted accounting principles in the United States. The GAAP measure most comparable to revenue on a constant currency basis is GAAP revenue. The GAAP measure most comparable to non-GAAP income from operations is GAAP income from operations. The GAAP measure most comparable to Non-GAAP net income and Adjusted EBITDA is GAAP net income. The GAAP measure most comparable to Non-GAAP net income per diluted share is GAAP net income per diluted share. A reconciliation of these non-GAAP financial measures to the corresponding GAAP measure is included below.

We define revenue on a constant currency basis as GAAP revenue, adjusted to reverse the impact of changes in the average exchange rates of currencies in which our international operations generated revenue and incurred expenses.

We define Non-GAAP net income as net income, excluding the after tax impact of non-cash, stock-based compensation expense and the amortization of acquired intangibles. We define EBITDA as net income, excluding depreciation and amortization, interest expense, loss on extinguishment of debt, other income (expense), foreign exchange gain (loss) and provision for income taxes, and we define Adjusted EBITDA as EBITDA, excluding non-cash, stock-based compensation expense.

Our management uses these non-GAAP measures when evaluating our operating performance and for internal planning and forecasting purposes. We believe that these measures help indicate underlying trends in our business, are important in comparing current results with prior period results, and are useful to investors and financial analysts in assessing our operating performance. For example, our international operations generate revenue and incur expenses that are denominated in foreign currencies. These amounts could be materially affected by currency fluctuations. Our principal exposures are to fluctuations in exchange rates for the United States dollar versus the Euro, British pound, Japanese yen, Chinese yuan and Korean won. Changes in currency exchange rates that are beyond our control can significantly affect our consolidated results of operations. We believe that disclosure of our revenue on a constant currency basis is useful as an indicator of demand for our solutions independent of the influence of currency exchange fluctuations. Management considers Adjusted EBITDA to be an important indicator of our operational strength and the performance of our business and a good measure of our historical operating trends. The non-GAAP financial information presented here should be considered in conjunction with, and not as a substitute for, or superior to, the financial information presented in accordance with GAAP and, in particular, should not be considered a

measure of our liquidity. There are significant limitations associated with the use of non-GAAP financial measures. Further, these measures may differ from the non-GAAP information, even where similarly titled, used by other companies and therefore should not be used to compare our performance to that of other companies. Investors should carefully consider the attached reconciliation of these non-GAAP financial measures to the comparable GAAP financial measures.

(1) The tax effect of non-cash stock based compensation expense and non-cash amortization of acquired intangibles is estimated using a blended rate equivalent to our annual estimated United States federal tax rate and our state tax rate, exclusive of our net federal benefit. This rate is based on our estimated annual GAAP income tax rate forecast. Our estimated tax rate on non-GAAP income is determined annually and may be adjusted during the year to take into account events or trends that we believe materially impact the estimated annual rate including, but not limited to, significant changes resulting from tax legislation, revenues and expenses and other significant events. Due to the differences in the tax treatment of items excluded from non-GAAP earnings, as well as the methodology applied to our estimated annual tax rates as described above, our estimated tax rate on non-GAAP income may differ from our GAAP tax rate and from our actual tax liabilities.

(2) Share amounts utilized on a fully diluted basis were approximately 14.7 million and 13.3 million, respectively, for the three and nine months ended October 31, 2013.
