This earnings release discusses non-GAAP gross margin, non-GAAP operating income (loss), non-GAAP net income (loss) and non-GAAP earnings (loss) per share, which are not financial measures as defined by GAAP. These financial measures are presented as supplemental measures of operating performance because the exclusion of certain expenses discussed below may provide a more meaningful analysis of our core operating results and comparison of quarterly results. Further, we believe it is useful for investors to understand how the expenses associated with the application of FASB ASC No. 718 are reflected on our statements of income. The reconciliation of financial measures should be reviewed in addition to and in conjunction with results presented in accordance with GAAP, and are intended to provide additional insight into our operations that, when viewed with its GAAP results and the accompanying reconciliation, offer a more complete understanding of factors and trends affecting our business. Other companies may define or calculate these measures differently, limiting the usefulness as a comparative measure. Because of these limitations, these non-GAAP financial measures should not be considered in isolation or as substitute for or superior to performance measures calculated in accordance with GAAP and should be read in conjunction with the financial statement tables.
