Income Taxes

The Company’s effective tax rate for the three and six months ended June 30, 2013 was 31.2% and 16.2%, respectively. The Company’s effective tax rate for the three and six months ended June 30, 2012 was 33.7% and 32.9%, respectively. The effective tax rates for the six months ended June 30, 2013 and 2012, and related income tax expense were lower than the U.S. statutory tax rate primarily due to the geographic mix of income and profits earned by the Company’s international subsidiaries being taxed at rates lower than the U.S. statutory rate. Additionally, certain tax incentives realized by the Company were recognized as discrete events during the quarter ended March 31, 2013. These incentives were reinstated under The American Taxpayer Relief Act of 2012 that was signed into law on January 2, 2013.

At June 30, 2013, the total amount of gross unrecognized tax benefits, which excludes interest and penalties, was approximately $41,964. At December 31, 2012, the total amount of gross unrecognized tax benefits, which excludes interest and penalties, was approximately $40,674. The net increase from December 31, 2012 was attributable to an increase in reserves for existing uncertain tax positions. If these benefits were recognized in a future period, the timing of which is not estimable, the net unrecognized tax benefit of $20,481, excluding interest and penalties, would impact the Company’s effective tax rate as of June 30, 2013. The Company accrues interest expense and, if applicable, penalties for any uncertain tax positions. Interest and penalties are classified as a component of income tax expense. At June 30, 2013 and December 31, 2012, the Company had accrued interest on unrecognized tax benefits of approximately $1,968 and $1,571, respectively.

The Company and its subsidiaries are subject to examination by federal, state and foreign tax authorities. The Internal Revenue Service commenced an examination of the Company’s U.S. federal tax filings for open tax years 2007 through 2009 during the quarter ended June 30, 2012. The statute of limitations for the Company’s tax filings varies by tax jurisdiction between fiscal years 2006 through present.

While the Company believes it has adequately provided for all tax positions, amounts asserted by taxing authorities could materially differ from the Company’s accrued positions as a result of uncertain and complex application of tax regulations. Additionally, the recognition and measurement of certain tax benefits include estimates and judgment by management and inherently includes subjectivity. Accordingly, the Company may record additional provisions or benefits due to U.S. federal, state, and foreign tax-related matters in the future as it revises estimates or settles or otherwise resolves the underlying matters.
