11.Income Taxes

 

Our effective income tax rate (ETR) for the nine months ended September 30, 2016 and 2015 was 32 percent and 38 percent, respectively. Our 2016 ETR decreased compared to 2015 primarily due to a decrease in non-deductible share-based compensation, which was driven largely by a decrease in our stock price during 2016 compared to 2015.

 

We are subject to federal and state taxation in the United States as well as various foreign jurisdictions. We are no longer subject to income tax examinations by the Internal Revenue Service and substantially all other major jurisdictions for tax years prior to 2011.

 

As of September 30, 2016 and 2015, our uncertain tax positions are approximately $0.5 million and $1.5 million, respectively, and we are unaware of any positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change within the next twelve months.
