• GAAP R&D and SG&A expenses between $30.0 million and $31.6 million. Non-GAAP(1) R&D and SG&A expenses between $22.5 million and $23.5 million. This excludes an estimate of stock-based compensation expenses in the range of $7.5 million to $8.1 million.

(1) Non-GAAP net income, non-GAAP earnings per share, non-GAAP gross margin, non-GAAP operating expenses and non-GAAP R&D and SG&A expenses differ from net income, earnings per share, gross margin, operating expenses, and R&D and SG&A expenses determined in accordance with GAAP (Generally Accepted Accounting Principles in the United States). Non-GAAP net income and non-GAAP earnings per share for the three and six months ended June 30, 2014 and 2013 exclude the effect of stock-based compensation expenses, acquisition-related expenses, a one-time cash award and their related tax effects. Non-GAAP gross margin for the three and six months ended June 30, 2014 and 2013 exclude the effect of stock-based compensation expenses. Non-GAAP operating expenses for the three and six months ended June 30, 2014 and 2013 exclude the effect of stock-based compensation expenses and acquisition-related expenses. Projected non-GAAP gross margin exclude the effect of stock-based compensation expenses. Projected non-GAAP R&D and SG&A expenses exclude the effect of stock-based compensation expenses. These non-GAAP financial measures are not prepared in accordance with GAAP and should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. A schedule reconciling non-GAAP financial measures is included at the end of this press release. MPS utilizes both GAAP and non-GAAP financial measures to assess what it believes to be its core operating performance and to evaluate and manage its internal business and assist in making financial operating decisions. MPS believes that the inclusion of non-GAAP financial measures, together with GAAP measures, provides investors with an alternative presentation useful to investors' understanding of MPS' core operating results and trends. Additionally, MPS believes that the inclusion of non-GAAP measures, together with GAAP measures, provides investors with an additional dimension of comparability to similar companies. However, investors should be aware that non-GAAP financial measures utilized by other companies are not likely to be comparable in most cases to the non-GAAP financial measures used by MPS.
