|Income Tax Disclosure [Abstract]
Our effective tax rate increased to 35.0% in the second quarter of 2013 compared with 34.5% in the same period of 2012, primarily due to a decrease in U.S. Federal and state tax credits relative to total pre-tax income, as well as unfavorable changes in the proportion of our taxable income in certain non-U.S. jurisdictions relative to total pre-tax income.
On a year-to-date basis, our effective tax rate declined to 32.8% in 2013 from 34.5% in 2012, as a portion of the gain from liquidating a foreign subsidiary was non-taxable (discussed further in note 15).
In June 2011, we received a RAR covering income taxes for tax years 2005 through 2007, in addition to the excise tax matters described in note 9. The income tax RAR proposed adjustments related to the value of acquired software and intangibles, research credit expenditures, and the amount of deductible costs associated with our British Pound Sterling Notes exchange offer completed in May 2007. Receipt of the RAR represents only the conclusion of the examination process. We disagree with some of the proposed adjustments related to these matters. Therefore, we filed protests and, in the third quarter of 2011, the IRS responded to our protests and forwarded the case to IRS Appeals.
We expect to begin discussions of these income tax matters with IRS Appeals within the next twelve months. It should be noted, however, that the ultimate resolution of these matters will result in a refund to UPS - even according to the adjustments proposed by the IRS.
At this time, we do not believe the ultimate resolution of these income tax matters will have a material effect on our financial condition, results of operations, or liquidity.
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. Items that may cause changes to unrecognized tax benefits include the timing of interest deductions and the allocation of income and expense between tax jurisdictions. 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. At this time, an estimate of the range of the reasonably possible change cannot be made.
