Use of Non-GAAP Measures
In addition to providing results that are determined in accordance with Generally Accepted Accounting Principles in the United States of America ("GAAP"), management uses non-GAAP gross margin, non-GAAP operating margin and non-GAAP net income to evaluate the Company's operating and financial results. We believe the presentation of non-GAAP results is useful to investors for analyzing our core business and business trends and comparing performance to prior periods, along with enhancing investors' ability to view the Company's results from management's perspective. The presentation of this additional information should not be considered a substitute for results prepared in accordance with GAAP. Tables presenting reconciliations from GAAP results to non-GAAP results are included at the end of this press release.

The Company defines non-GAAP net income as net loss before amortization of intangible assets, stock-based compensation, restructuring charges, debt refinancing costs, legal-related costs, unrealized loss (gain) on foreign exchange, VAT settlement, and the tax effects of the foregoing adjustments.

A reconciliation of our guidance for non-GAAP net income per diluted share for the subsequent quarter is not available due to fluctuations in the geographic mix of our earnings from quarter to quarter, which impacts our tax rate and cannot be reasonably predicted or determined. As a result, such reconciliation is not available without unreasonable efforts and we are unable to determine the probable significance of the unavailable information.
