Basis of Presentation	Basis of Presentation Certain information and footnote disclosures normally included in the financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission, although we believe that the disclosures are adequate to make the information presented not misleading. These Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements included in our 2015 Annual Report to Shareholders. The information furnished reflects all adjustments that, in the opinion of management, were necessary for a fair statement of the results of operations for the periods presented. Such adjustments were of a normal recurring nature, unless otherwise disclosed. Goodwill and Intangible Assets In accordance with the current accounting guidance for goodwill and other intangible assets, we perform an annual impairment test of goodwill at our reporting unit level and indefinite-lived intangible assets at our unit of account level during the third quarter, or more frequently if events or circumstances change that would more likely than not reduce the fair value of our reporting units below their carrying value. We performed our annual impairment test of our goodwill and indefinite-lived intangible assets during the third quarter of 2016 and determined that there was no impairment of our goodwill or our indefinite-lived intangible assets. Significant assumptions used in our annual goodwill impairment test during the third quarter of 2016 included: expected future revenue growth rates, operating unit profit margins, working capital levels, discount rates ranging from 10.8% to 15.3%, and a terminal value multiple. The expected future revenue growth rates and operating unit profit margins were determined after taking into consideration our historical revenue growth rates and operating unit profit margins, our assessment of future market potential, and our expectations of future business performance. Payroll Tax Credit In March 2016 and July 2015, we entered into an agreement to sell a portion of our French payroll tax credits earned in 2015 and 2014, respectively, for net proceeds of $143.1 (€129.9) and $132.8 (€120.1), respectively. We derecognized these receivables upon the sale date as the terms of the agreement are such that the transaction qualifies for sale treatment according to the accounting guidance on the transfer and servicing of assets. Subsequent Events We have evaluated events and transactions occurring after the balance sheet date through our filing date and have accrued or disclosed, if appropriate.
