Non-GAAP Financial Measures:

We have provided in this release non-GAAP financial information including bookings, adjusted EBITDA, non-GAAP net income, non-GAAP EPS, and free cash flow, as a supplement to the consolidated financial statements, which are prepared in accordance with generally accepted accounting principles (“GAAP”). Management uses these non-GAAP financial measures internally in analyzing our financial results to assess operational performance and liquidity. The presentation of this financial information is not intended to be considered in isolation or as a substitute for the financial information prepared in accordance with GAAP. We believe that both management and investors benefit from referring to these non-GAAP financial measures in assessing our performance and when planning, forecasting and analyzing future periods. We believe these non-GAAP financial measures are useful to investors because they allow for greater transparency with respect to key financial metrics we use in making operating decisions and because our investors and analysts use them to help assess the health of our business. We have provided reconciliations between our historical and fourth quarter 2013 outlook for non-GAAP financial measures to the most directly comparable GAAP financial measures.

Some limitations of bookings, adjusted EBITDA, non-GAAP net income, non-GAAP EPS, and free cash flow:

Because of these limitations, you should consider bookings, adjusted EBITDA, non-GAAP net income (loss), non-GAAP EPS, and free cash flow, along with other financial performance measures, including revenue, net income (loss), diluted net loss per share, cash flow from operations and GAAP operating margin and our other financial results presented in accordance with GAAP. See the GAAP to non-GAAP reconciliations below for further details.
