5.	Income Taxes

For the three and six months ended June 30, 2017, we had an effective income tax rate from continuing operations of 35.7% and 36.7%, respectively, each of which was favorably impacted by the tax benefits of share-based awards following the adoption of ASU 2016-09 on January 1, 2017. For the three and six months ended June 30, 2016, we did not record income tax expense because we followed the intra-period tax allocation guidance in ASC 740-20 and the example in ASC 740-20-55-14, which requires that the amount of tax attributable to the current year income from continuing operations be determined by a computation that does not consider the tax effects of items that are excluded from income from continuing operations (e.g. discontinued operations). We had net operating loss carryforwards from 2015 subject to a valuation allowance at December 31, 2015, which, upon reversal of the valuation allowance in the first six months of 2016, we utilized to offset income from continuing operations for the three and six months ended June 30, 2016.

At June 30, 2017, we had approximately $134.8 million of federal loss carryforwards and approximately $166.5 million of state loss carryforwards.

We file income tax returns in the U.S. Federal jurisdiction and in various state and foreign jurisdictions. Our 2014 federal income tax return is currently under IRS examination. Tax years remaining subject to examination in the U.S. Federal jurisdiction include 2013 to present.
