Management defines "Non-GAAP Adjusted EBITDA" as the sum of GAAP net loss before provision for income taxes, acquisition-related expenses, total other (income) expense, stock-based compensation expense, depreciation and amortization, severance, gain on sale, amortization of acquired intangibles, acquisition related, patent litigation and recall costs, contingent consideration and goodwill impairment charges. Management considers this non-GAAP financial measure to be an important indicator of the Company's operational strength and performance of its business and a good measure of its historical operating trends, in particular the extent to which ongoing operations impact the Company's overall financial performance.Management defines "Non-GAAP Adjusted Net Loss" as the sum of GAAP net loss before provision for the gain on sale of asset, severance, transaction, patent litigation and recall costs, contingent consideration and goodwill impairment charges.

- Stock-based compensation expense: excluded as these are non-cash expenses that management does not consider part of ongoing operating results when assessing the performance of the Company's business, and also because the total amount of expense is partially outside of the Company's control as it is based on factors such as stock price volatility and interest rates, which may be unrelated to our performance during the period in which the expense is incurred.
- Amortization of acquired intangibles: acquisition-related expenses are reported at the time acquisition costs are incurred, and purchased intangibles are amortized over a period of several years after the acquisition and generally cannot be changed or influenced by management after the acquisition. Accordingly, these items are not considered by management in making operating decisions, and management believes that such expenses do not have a direct correlation to future business operations. Thus, including such charges does not accurately reflect the performance of the Company's ongoing operations for the period in which such charges are incurred.
- Severance: relates to costs incurred due to the termination of certain employees. The Company provides compensation to certain employees as an accommodation upon termination of employment without cause. Management believes that excluding severance costs from operating results provides investors with a better means for measuring current Company performance.
- Gain on sale: relates to a gain on the one-time sale of a non-core patent in the second quarter of 2010. Since the proceeds are non-recurring, management believes that it should be excluded when evaluating core operations.
- Acquisition-related expenses: relates to transition and integration cost as well as professional service fees due to the acquisition of Xoft, Inc. The Company does not consider these acquisition-related costs to be related to the organic continuing operations of the acquired businesses and are generally not relevant to assessing or estimating the long-term performance of the acquired assets.
- Recall and patent lawsuits: These expenses consist primarily of investigation, audit, legal and other professional fees related to the recall and patent litigation, as well as recoveries received from third parties. The Company excludes these costs and recoveries from its non-GAAP measures primarily because the Company believes that these costs and recoveries have no direct correlation to the core operation of the Company.
- Contingent consideration: the Company reviews the fair value of contingent consideration on a quarterly basis and, accordingly, recorded a gain due to a reduction of the contingent consideration liability related to the acquisition of Xoft, Inc. This amount arose from the Company's acquisition of Xoft, Inc. and has no direct correlation to the core operation of the Company.
- Goodwill impairment charges: the Company recorded a goodwill impairment loss during the third quarter of 2011 primarily due to current market conditions affecting the price of its common stock. The Company does not consider the impairment charge to be directly related to the continuing operations of the business.
