Adjusted net income is calculated based on the net income in our financial statements excluding non-cash equity-based compensation charges recorded in accordance with FASB ASC Topic 718, non-cash expense resulting from amortization of acquired intangible assets, non-cash income (loss) reflecting changes in the fair value of embedded currency conversion derivatives resulting from the application of FASB ASC Topic 815 and the resulting income tax (increase) decrease of the above items.Adjusted EBITDA is calculated by adding to operating income, non-cash equity-based compensation charge, depreciation and amortization. The company has excluded intangible assets amortization expense from its non-GAAP net income and EBITDA measurements, primarily because it represents a significant non-cash expense and because the company evaluates its performance excluding intangible assets amortization expense. Amortization of intangible assets is consistent in amount and frequency but is significantly affected by the timing and size of the company's acquisitions. Investors should note that the use of intangible assets contributed to the Company's revenues earned during the periods presented and will contribute to the Company's future period revenues as well. Intangible assets amortization expense will recur in future periods. Management uses these non-GAAP financial measures to assess its operational performance, for financial and operational decision-making, and as a means to evaluate period-to-period comparisons on a consistent basis. Management believes that these non-GAAP financial measures provide meaningful supplemental information regarding the Company's performance by excluding certain non-cash expenses that are not directly attributable to its core operating results. The non-GAAP measurements are intended only as a supplement to the comparable GAAP measurements and the company compensates for the limitations inherent in the use of non-GAAP measurements by using GAAP measures in conjunction with the non-GAAP measurements. As a result, investors should consider these non-GAAP measurements in addition to, and not in substitution for, or as superior to, measurements of financial performance prepared in accordance with GAAP.
