Use of Non-GAAP Financial Measures

To provide investors with additional information regarding our financial results, this press release presents references to Adjusted EBITDA, as well as Non-GAAP income (loss) and Non-GAAP basic earnings (loss) per share (both of which exclude the impact of a facilities exit charge incurred in the third quarter of 2011). All of these measures are non-GAAP financial measures. We have provided GAAP to Non-GAAP reconciliations within this earnings release, including Adjusted EBITDA to net income (loss), the most directly comparable GAAP financial measure, and Non-GAAP income (loss) to net income (loss).

Adjusted EBITDA is a key metric used by our management and board of directors to measure operating performance and trends and to prepare and approve our annual budget. In particular, the exclusion of certain expenses in calculating Adjusted EBITDA facilitates operating performance comparisons on a period-to-period basis.

Our use of Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP. Some of these limitations are:

Because of these limitations, you should consider Adjusted EBITDA alongside other financial performance measures, including various cash flow metrics, net loss and our other GAAP results.

Our use of Non-GAAP net income (loss) and Non-GAAP basic earnings (loss) per share excludes the impact of a facility exit charge. We believe the exclusion of the facilities charge facilitates operating performance comparisons on a period-to-period basis. However, you should not consider these metrics in isolation or as substitutes for analysis of our results as reported under GAAP.
