Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes The effective income tax rate for continuing operations was 32.1% and 33.9% for the three months ended March 31, 2015 and March 31, 2014, respectively. The decrease in the effective income tax rate was primarily the result of a non-recurring benefit recorded during the three months ended March 31, 2015. At the end of each interim period, we estimate the annual effective tax rate and apply that rate to our ordinary quarterly earnings. The tax expense or benefit related to significant, unusual or extraordinary items that will be separately reported or reported net of their related tax effect, and are individually computed, are recognized in the interim period in which those items occur. In addition, the effect of changes in enacted tax laws or rates or tax status is recognized in the interim period in which the change occurs. As of March 31, 2015 and December 31, 2014, the total amount of federal, state and local, and foreign unrecognized tax benefits was $137 million and $118 million, respectively, exclusive of interest and penalties. The increase in unrecognized tax benefits relates primarily to tax positions of prior years. We recognize accrued interest and penalties related to unrecognized tax benefits in interest expense and operating-related expense, respectively. In addition to the unrecognized tax benefits, as of March 31, 2015 and December 31, 2014, we had $25 million and $23 million respectively of accrued interest and penalties associated with uncertain tax positions. Based on the current status of income tax audits, we believe that the total amount of unrecognized tax benefits may significantly decrease in the next twelve months. Although the ultimate resolution of our tax audits is unpredictable, the resulting change in our unrecognized tax benefits could have a material impact on our results of operations and/or cash flows.
