To supplement MoSys’ consolidated financial statements presented in accordance with GAAP, MoSys uses non-GAAP financial measures that exclude from the statement of operations the effects of stock-based compensation and amortization of recorded intangible assets. MoSys’ management believes that the presentation of these non-GAAP financial measures is useful to investors and other interested persons because they are one of the primary indicators that MoSys’ management uses for planning and forecasting future performance. MoSys’ management believes that the presentation of non-GAAP financial measures that exclude these items is useful to investors because MoSys’ management does not consider these charges part of the day-to-day business or reflective of the core operational activities of the Company that are within the control of management or that would be used to evaluate management’s operating performance.

Investors are encouraged to review the reconciliation of these non-GAAP financial measures to the comparable GAAP results, which is provided in a table below the Condensed Consolidated Statements of Operations. The non-GAAP financial measures disclosed by the Company should not be considered a substitute for, or superior to, financial measures calculated in accordance with GAAP, and the financial results calculated in accordance with GAAP and reconciliations to those financial statements should be carefully evaluated. The non-GAAP financial measures used by the Company may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies. For additional information regarding these non-GAAP financial measures, and management’s explanation of why it considers such measures to be useful, refer to the Form 8-K dated October 19, 2012, that the Company filed with the Securities and Exchange Commission.
