Income Taxes	Income Taxes Our effective income tax rate was 35.2% and 31.6% in the first quarter of 2016 and 2015, respectively. The increase from the first quarter of 2015 is primarily due to a change in the mix of earnings attributable to higher-taxing jurisdictions. The first quarter of 2015 also included a benefit from the release of valuation allowance on certain state tax attributes. Our accounting policy is to account for interest expense and penalties related to uncertain tax positions as income tax expense. As of March 31, 2016, we have approximately $1.5 million of accrued interest related to uncertain tax positions included in the $13.2 million of unrecognized tax benefits, $13.1 million of which, if recognized, would impact the effective tax rate.

Our effective income tax rate was 35.2% and 31.6% in the first quarter of 2016 and 2015, respectively. The increase from the first quarter of 2015 is primarily due to a change in the mix of earnings attributable to higher-taxing jurisdictions. The first quarter of 2015 also included a benefit from the release of valuation allowance on certain state tax attributes.

Our accounting policy is to account for interest expense and penalties related to uncertain tax positions as income tax expense. As of March 31, 2016, we have approximately $1.5 million of accrued interest related to uncertain tax positions included in the $13.2 million of unrecognized tax benefits, $13.1 million of which, if recognized, would impact the effective tax rate. It is possible that up to $9.1 million of our currently unrecognized tax benefits could be recognized within 12 months as a result of projected resolutions of worldwide tax disputes or expiration of the statute of limitations.
