Non-GAAP MeasuresA non-GAAP financial measure is a numerical measure of a company’s performance, financial position, or cash flows that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with GAAP. Non-GAAP measures are not in accordance with, nor are they a substitute for, GAAP measures. Other companies may use different non-GAAP measures and presentation of results. We provide non-GAAP measures of non-GAAP income (loss) from operations and non-GAAP net income (loss) as a supplement to financial results based on GAAP income from operations and GAAP net income. The Company believes that the additional non-GAAP measures are useful to investors for the purpose of financial analysis. We believe the presentation of non-GAAP measures provides investors with additional insight into underlying operating results and prospects for the future by excluding gains, losses and other charges that are considered by management to be outside of the Company’s core operating results. Management uses these measures internally to evaluate the Company’s in-period operating performance before taking into account these non-operating gains, losses and charges. In addition, the measures are used for planning and forecasting of the Company’s performance in future periods. In deriving non-GAAP income (loss) from operations from GAAP income (loss) from operations, we exclude stock-based compensation charges, amortization of intangible assets, as well as restructuring and impairment charges. In deriving non-GAAP net income (loss) from GAAP net income (loss), we further exclude gain or loss on the embedded derivative and loss on extinguishment of debt. Stock-based compensation charges, amortization of intangible assets, gain or loss on the embedded derivative and loss on extinguishment of debt represent charges that recur in amounts unrelated to the Company’s operations. Restructuring and impairment costs relate to strategic initiatives that result in short term increases in costs that end with the fulfillment of the initiative and cost reductions in future periods.
