To supplement our consolidated financial statements presented on a GAAP basis, Autodesk provides investors with certain non-GAAP measures including non-GAAP net income, non-GAAP net income per share, non-GAAP cost of license and other revenue, non-GAAP gross profit, non-GAAP operating expenses, non-GAAP income from operations and non-GAAP provision for income taxes. These non-GAAP financial measures are adjusted to exclude certain costs, expenses, gains and losses, including stock-based compensation expense, amortization of purchased intangibles, restructuring charges, discrete tax provision items and related income tax expenses. See our reconciliation of GAAP financial measures to non-GAAP financial measures herein. We believe these exclusions are appropriate to enhance an overall understanding of our past financial performance and also our prospects for the future, as well as to facilitate comparisons with our historical operating results. These adjustments to our GAAP results are made with the intent of providing both management and investors a more complete understanding of Autodesk's underlying operational results and trends and our marketplace performance. For example, the non-GAAP results are an indication of our baseline performance before gains, losses or other charges that are considered by management to be outside our core operating results. In addition, these non-GAAP financial measures are among the primary indicators management uses as a basis for our planning and forecasting of future periods.

There are limitations in using non-GAAP financial measures because the non-GAAP financial measures are not prepared in accordance with generally accepted accounting principles and may be different from non-GAAP financial measures used by other companies. The non-GAAP financial measures are limited in value because they exclude certain items that may have a material impact upon our reported financial results. The presentation of this additional information is not meant to be considered in isolation or as a substitute for the directly comparable financial measures prepared in accordance with generally accepted accounting principles in the United States. Investors should review the reconciliation of the non-GAAP financial measures to their most directly comparable GAAP financial measures as provided in the tables accompanying this press release.

(b) Effective in the second quarter of fiscal 2012, Autodesk changed the way it calculates constant currency growth rates and foreign currency impact on Total Net Revenue, and Cost of Revenue and Total Operating Expenses. Under the new methodology, all hedging gains and losses are removed from the calculation of constant currency growth rates, where previously Autodesk had not excluded hedging gains and losses from the prior period. Autodesk changed the way it calculates foreign currency impact on Total Net Revenue, and Cost of Revenue and Total Operating Expenses to include the impact of Autodesk's hedging program on both the current and prior period. Autodesk believes these changes are more useful to the users of Autodesk's financial information as they more fully reflect the underlying business growth rates and the impact of movements in foreign currency on Autodesk's U.S. dollar financial results. All prior period comparative information has been revised to conform to the current methodology.
