Income Tax Disclosure [Abstract] |
Income Taxes | 14. Income Taxes The effective tax rate was 34.7 percent and 34.2 percent for the three months ended March 31, 2016 and 2015, respectively. The tax rates in both periods primarily reflected the level of pretax income in relation to recurring permanent tax benefits and the geographic mix of business. Additionally, the effective tax rate in both periods reflected the resolution of certain prior years’ tax items. The Company is under continuous examination by the Internal Revenue Service (IRS) and tax authorities in other countries and states in which the Company has significant business operations. The tax years under examination and open for examination vary by jurisdiction. The IRS has completed its field examination of the Company’s federal tax returns for years through 2007; however, refund claims for certain years continue to be reviewed by the IRS. In addition, the Company is currently under examination by the IRS for the years 2008 through 2014. The Company believes it is reasonably possible that its unrecognized tax benefits could decrease within the next 12 months by as much as $263 million principally as a result of potential resolutions of prior years’ tax items with various taxing authorities. The p rior years’ tax items include unrecognized tax benefits relating to the deductibility of certain expenses or losses and the attribution of taxable income to a particular jurisdiction or jurisdictions. Of the $263 million of unrecognized tax benefits, approximately $21 million relates to amounts that if recognized would be recorded in shareholders’ equity and would not impact the Company’s results of operations or its effective tax rate.
