|Income Tax Disclosure [Abstract]|
Our effective tax rate decreased to 35.3% in the first quarter of 2016 compared with 35.5% in the same period of 2015, primarily due to favorable changes in the proportion of our taxable income in certain U.S. and non-U.S. jurisdictions. This was partially offset by a decrease in U.S. Federal and state tax credits relative to total pre-tax income.
As discussed in our Annual Report on Form 10-K for the year ended December 31, 2015, we have recognized liabilities for uncertain tax positions. We reevaluate these uncertain tax positions on a quarterly basis. A number of years may elapse before an uncertain tax position is audited and ultimately settled. It is difficult to predict the ultimate outcome or the timing of resolution for uncertain tax positions. It is reasonably possible that the amount of unrecognized tax benefits could significantly increase or decrease within the next twelve months. However, an estimate of the range of reasonably possible outcomes cannot be made. Items that may cause changes to unrecognized tax benefits include various state filing positions, the allocation of income and expense between tax jurisdictions and other transfer pricing matters. These changes could result from the settlement of ongoing litigation, the completion of ongoing examinations, the expiration of the statute of limitations or other unforeseen circumstances.
The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
