Income Taxes	Income Taxes The Company's tax provision for interim periods is determined using an estimate of its annual effective tax rate, adjusted for discrete items. The Company’s reported effective income tax rate was 702.0% and 37.4% for the three months ended June 30, 2016 and 2015, respectively, and (2,038.9)% and 39.9% for the six months ended June 30, 2016 and 2015, respectively. The Company’s effective income tax rate differs from the U.S. federal statutory rate each year due to certain operations that are subject to tax incentives, state and local taxes, and foreign taxes that are different than the U.S. federal statutory rate. In addition, the effective tax rate can be impacted each period by discrete factors and events. The effective tax rates were affected by the fair value changes to contingent consideration in each period. Portions of the total amount recognized from fair value changes to contingent consideration relate to non-taxable acquisitions for which deferred taxes are not recognized, consistent with the treatment of goodwill and intangible assets for those acquisitions under U.S. GAAP. In the three months ended June 30, 2016 and 2015, $7.3 million and $0.7 million, respectively, was recognized as expense from fair value changes to contingent consideration, and in the six months ended June 30, 2016 and 2015, $9.2 million and $1.0 million, respectively, was recognized as expense from fair value changes to contingent consideration, which did not result in recognition of a deferred tax asset, therefore, increasing the effective tax rate for these periods.
