INCOME TAXES
The Company’s income tax provision consists of federal, state and foreign income taxes. The tax provisions for the three months ended March 31, 2016 and 2015 were based on the estimated effective tax rates applicable for the full years ending December 31, 2016 and 2015, which includes items specifically related to the interim periods. The Company’s effective tax rate was 37.6% and 36.8% for the three months ended March 31, 2016 and 2015, respectively. The change in the Company's effective tax rate for the three months ended March 31, 2016 was primarily a result of the geographic mix of pretax income and the varying effective tax rates in the countries and states in which the Company operates.
As of March 31, 2016 and December 31, 2015, the Company had unrecognized tax benefits of approximately $4.1 million and $4.4 million, respectively. These unrecognized tax benefit amounts would affect the effective tax rate if recognized. As of March 31, 2016, the Company is subject to U.S. Federal income tax examinations for the tax years 2012 through 2015, and to non-U.S. income tax examinations for the tax years 2009 through 2015. In addition, the Company is subject to state and local income tax examinations for the tax years 2011 through 2015.
