INCOME TAXES

The following table provides a summary of the Company’s effective tax rate:



	Three Months Ended June 30,				Six Months Ended June 30,
	2015		2014		2015		2014

Reported tax rate	34.0	%	32.9	%	33.7	%	37.0	%

The Company’s effective income tax rates for the three months ended June 30, 2015 and 2014 were 34.0% and 32.9%, respectively. The primary drivers of the higher tax rate for the three months ended June 30, 2015 were a tax expense of $0.4 million for nondeductible costs relating to the spine spin-off transaction and a tax expense of $0.4 million relating to foreign tax returns filed during the quarter.

The Company's effective income tax rates for the six months ended June 30, 2015 and 2014 were 33.7% and 37.0%, respectively. The primary drivers of the overall tax rate for the six months ended June 30, 2014 were a tax expense of $1.1 million relating to foreign and state income tax audit settlements and a tax expense of $0.3 million relating to a change in state filing positions.

The Company expects its effective income tax rate for the full year to be approximately 32%, resulting largely from nondeductible spine spin-off costs and audit settlements offset by the release of uncertain tax positions, as well as the jurisdictional mix of pretax income in U.S.-based operations relative to foreign operations. This estimate could be revised in the future as additional information is presented to the Company.
