Non-GAAP Financial Measures

To supplement the financial measures prepared in accordance with generally accepted accounting principles in the United States, or GAAP, this press release presents non-GAAP income from operations and non-GAAP net income by excluding share-based compensation expenses from income from operations and net income, respectively. The Company believes these non-GAAP financial measures are important to help investors understand the Company’s operating and financial performance, compare business trends among different reporting periods on a consistent basis and assess the Company’s core operating results, as they exclude certain expenses that are not expected to result in cash payments.  The use of the above non-GAAP financial measures has certain limitations. Share-based compensation expenses have been and will continue to be incurred in the future and are not reflected in the presentation of the non-GAAP financial measures, but should be considered in the overall evaluation of the Company’s results. The Company compensates for these limitations by providing the relevant disclosure of its share-based compensation expenses in the reconciliations to the most directly comparable GAAP financial measures, which should be considered when evaluating the Company’s performance. These non-GAAP financial measures should be considered in addition to financial measures prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, financial measures prepared in accordance with GAAP.  Reconciliation of each of these non-GAAP financial measures to the most directly comparable GAAP financial measure is set forth at the end of this release.
