(1) Non-GAAP net income, non-GAAP net income per share, non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating income, non-GAAP other income, net and non-GAAP income before income taxes differ from net income, net income per share, gross margin, operating expenses, operating income, other income, net and income before income taxes determined in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”). Non-GAAP net income and non-GAAP net income per share exclude the effect of stock-based compensation and related expenses, which include stock-based compensation expense and employer payroll taxes in relation to the stock-based compensation, net deferred compensation plan expense (income), amortization of acquisition-related intangible assets and related tax effects. Non-GAAP net income and non-GAAP net income per share in the prior year also exclude the recognition of a tax benefit granted to a foreign subsidiary.

Non-GAAP gross margin excludes the effect of stock-based compensation and related expenses, amortization of acquisition-related intangible assets and deferred compensation plan expense. Non-GAAP operating expenses exclude the effect of stock-based compensation and related expenses, amortization of acquisition-related intangible assets and deferred compensation plan expense. Non-GAAP operating income excludes the effect of stock-based compensation and related expenses, amortization of acquisition-related intangible assets and deferred compensation plan expense. Non-GAAP other income, net excludes the effect of deferred compensation plan income. Non-GAAP income before income taxes excludes the effect of stock-based compensation and related expenses, amortization of acquisition-related intangible assets and net deferred compensation plan expense (income). Projected non-GAAP gross margin excludes the effect of stock-based compensation and related expenses, and amortization of acquisition-related intangible assets.

Projected non-GAAP operating expenses exclude the effect of stock-based compensation and related 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’s 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. See the GAAP to non-GAAP reconciliations in the tables set forth below.
