INCOME TAXES
The Company’s income tax provision consists of federal, state and foreign income taxes. The tax provisions for the three months ended June 30, 2017 and 2016 were based on the estimated effective tax rates applicable for the full years ending December 31, 2017 and 2016 and includes items specifically related to the interim periods. The Company’s effective tax rate was 31.3% and 34.6% for the six months ended June 30, 2017 and 2016, respectively. The decrease in the Company's effective tax rate for the six months ended June 30, 2017 was due primarily to the adoption of ASU 2016-09 in the third quarter of 2016, which impacted the accounting treatment of excess tax benefits related to vesting of equity awards in the six months ended June 30, 2017. This resulted in the realization of tax benefits as a reduction to income tax expense in the quarter. In addition, the effective tax rate was affected by the geographic mix of pretax income and the varying effective tax rates in the countries and states in which the Company operates.
As of June 30, 2017 and December 31, 2016, the Company had unrecognized tax benefits of approximately $0.9 million, respectively. These unrecognized tax benefit amounts would affect the effective tax rate if recognized. As of June 30, 2017, the Company is subject to U.S. Federal Income Tax examination for the tax years 2007 through 2016, and to non-U.S. income tax examination for the tax years 2010 to 2016. In addition, the Company is subject to state and local income tax examinations for the tax years 2007 through 2016.
