[1] | Intangible asset amortization related to acquisitions was excluded from operating costs within the reportable segments and corporate expenses, and shown separately.
[2] | The French business tax, as disclosed in Note 5 to the Consolidated Financial Statements, is reported in Provision for income taxes rather than in Cost of services, in accordance with the current accounting guidance on income taxes. However, we view this tax as operational in nature. Accordingly, the financial information reviewed internally continues to include the French business tax within the Operating unit profit of our France reportable segment. Therefore, we have shown the amount of the French business tax above to reconcile to our Earnings (loss) before income taxes.
[3] | The U.S. revenues above represent revenues from our company-owned branches and franchise fees received from our franchise operations, which are discussed further on the financial highlights page.
[4] | Corporate assets include assets that were not used in the operations of any segment, the most significant of which were purchased intangibles and cash.
