PTC provides non-GAAP supplemental information to its financial results. Non-GAAP revenue, operating expenses, margin and EPS exclude the effect of purchase accounting on the fair value of the acquired deferred maintenance balance of MKS Inc., stock-based compensation expense, amortization of acquired intangible assets, acquisition-related expenses, restructuring charges, certain foreign currency transaction losses, and the related tax effects of the preceding items and any one-time tax items. We use these non-GAAP measures, and we believe that they assist our investors, to make period-to-period comparisons of our operational performance because they provide a view of our operating results without items that are not, in our view, indicative of our core operating results. We believe that these non-GAAP measures help illustrate underlying trends in our business, and we use the measures to establish budgets and operational goals, communicated internally and externally, for managing our business and evaluating our performance. We believe that providing non-GAAP measures affords investors a view of our operating results that may be more easily compared to the results of peer companies. In addition, compensation of our executives is based in part on the performance of our business based on these non-GAAP measures. However, non-GAAP information should not be construed as an alternative to GAAP information as the items excluded from the non-GAAP measures often have a material impact on PTC’s financial results. Management uses, and investors should consider, non-GAAP measures in conjunction with our GAAP results.

Forward-Looking Statements

Statements in this press release that are not historic facts, including statements about our fiscal 2012 and other future financial and growth expectations and anticipated tax rates are forward-looking statements that involve risks and uncertainties that could cause actual results to differ materially from those projected. These risks include the possibility that customers may not purchase our solutions when or at the rates we expect, the possibility the foreign currency exchange rates may vary from our expectations and thereby affect our reported revenue and expense, the possibility that we may not achieve the license, services or maintenance growth rates that we expect, which could result in a different mix of revenue between license, service and maintenance and could impact our EPS results, the possibility that strategic customer wins may not generate the revenue growth or cost efficiencies we expect, the possibility that resource constraints could adversely affect our revenue, and the possibility that our strategic investments, and organizational realignment and restructuring may not generate the revenue growth or operating margin improvements we expect. In addition, our assumptions concerning our future GAAP and non-GAAP effective income tax rates are based on estimates and other factors that could change, including the geographic mix of our revenue, expenses and profits and loans and cash repatriations from foreign subsidiaries. Other risks and uncertainties that could cause actual results to differ materially from those projected are detailed from time to time in reports we file with the Securities and Exchange Commission, including our Annual Report on Form 10-K and our Quarterly Reports on Form 10-Q.
