[1] | Included above in the impact of the non-U.S. tax rate difference was the French business tax, which has been classified as a component of income tax beginning in January 2010, in accordance with the current accounting guidance on income taxes. Prior to January 2010, the French business tax had been presented as non-income tax and included as a component of Cost of services. The French government changed the business tax from an asset- based tax to an income-based tax, thereby requiring the classification of this tax as income tax effective January 1, 2010.
[2] | The 2010 amounts originally presented above for Intangible assets, Net operating losses and Other have been revised by ($91.3), ($14.4) and $105.7, respectively, to correct the prior year presentation. This change did not affect the deferred tax assets and liabilities reported in the 2010 Consolidated Balance Sheet.
