Use of non-GAAP financial measures

The non-GAAP data included herein, which excludes certain items as described below, are non-GAAP financial measures. Our management believes that these non-GAAP financial measures are useful information for investors and shareholders of our Company in gauging our results of operations (x) on an ongoing basis after excluding mergers, acquisitions and divestments related expense or gains and reorganization-related charges or gains, and (y) excluding non-cash items such as stock-based compensation expenses, acquired intangible assets amortization, including intangible assets amortization related to equity method investments, impairment of long-lived assets, changes in fair value of obligations in connection with acquisitions and the corresponding tax effect of those items. These non-GAAP adjustments either do not reflect actual cash outlays that impact our liquidity and our financial condition or have a non-recurring impact on the statement of operations, as assessed by management. These non-GAAP financial measures are presented to permit investors to more fully understand how management assesses our performance for internal planning and forecasting purposes. The limitations of using these non-GAAP financial measures as performance measures are that they provide a view of our results of operations without including all items indicated above during a period, which may not provide a comparable view of our performance to other companies in our industry. Investors and other readers should consider non-GAAP measures only as supplements to, not as substitutes for or as superior measures to, the measures of financial performance prepared in accordance with GAAP. Reconciliation between results on a GAAP and non-GAAP basis is provided in a table below.
