Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES Uncertain Tax Positions We are subject to tax audits in numerous jurisdictions in the U.S. and foreign countries. Tax audits by their very nature are often complex and can require several years to complete. In the normal course of business, we are subject to challenges from the Internal Revenue Service (IRS) and other tax authorities regarding amounts of taxes due. These challenges may alter the timing or amount of taxable income or deductions, or the allocation of income among tax jurisdictions. As part of our calculation of the provision for income taxes on earnings, we recognize the tax benefit from uncertain tax positions that are at least more likely than not of being sustained upon audit based on the technical merits of the tax position. The tax benefit to be recognized is measured as the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. Such calculations require management to make estimates and judgments with respect to the ultimate outcome of a tax audit. Actual results could vary materially from these estimates. We reevaluate uncertain tax positions each quarter based on factors including, but not limited to, changes in facts or circumstances, expiration of statutes of limitations, changes in tax law, effectively settled issues under audit, and new audit activity. Depending on the jurisdiction, such a change in recognition or measurement may result in the recognition of a tax benefit or an additional charge to the tax provision in the period. The following is a summary of tax years that are no longer subject to examination: Federal — audits of our U.S. federal income tax returns are closed through fiscal year 2008. State — for the majority of states, tax returns are closed through fiscal year 2008. Foreign — we are no longer subject to foreign tax examinations by tax authorities for tax years before 2005 in Canada, 2006 in Brazil, 2008 in Mexico and 2010 in the U.K., which are our major foreign tax jurisdictions. Refer to Note (C), “Discontinued Operations,” for further discussion on various assessments related to our former South American operations. At March 31, 2013 and December 31, 2012, the total amount of gross unrecognized tax benefits (excluding the federal benefit received from state positions) was $53.2 million and $52.3 million, respectively. Unrecognized tax benefits related to federal, state and foreign tax positions may decrease by $2.3 million by March 31, 2014, if audits are completed or tax years close. Like-Kind Exchange Program We have a like-kind exchange program for certain of our revenue earning equipment operating in the U.S. Pursuant to the program, we dispose of vehicles and acquire replacement vehicles in a form whereby tax gains on disposal of eligible vehicles are deferred. To qualify for like-kind exchange treatment, we exchange through a qualified intermediary eligible vehicles being disposed of with vehicles being acquired, allowing us to generally carryover the tax basis of the vehicles sold (“like-kind exchanges”). The program results in a material deferral of federal and state income taxes. As part of the program, the proceeds from the sale of eligible vehicles are restricted for the acquisition of replacement vehicles and other specified applications. Due to the structure utilized to facilitate the like-kind exchanges, the qualified intermediary that holds the proceeds from the sales of eligible vehicles and the entity that holds the vehicles to be acquired under the program are required to be consolidated in the accompanying Consolidated Condensed Financial Statements in accordance with U.S. GAAP. At March 31, 2013 and December 31, 2012, these consolidated entities had total assets, primarily revenue earning equipment, and total liabilities, primarily accounts payable, of $174.3 million and $25.8 million, respectively. During 2012, we were in a net operating loss position for tax purposes and were not realizing any benefits from the like-kind exchange program. We also had restricted cash in the program that could be used for other purposes. As a result, in the second quarter of 2012, we temporarily ceased utilizing the program while we restructured the processes relating to the purchase and sale of our vehicles and evaluated other tax planning alternatives. Although these actions did not impact our 2012 tax provision or capital spending program, our cash flows increased $19 million from the release of the program's restricted cash. In the first quarter of 2013, once we had completed our restructuring and evaluation, we reinstated our like-kind exchange program and expect to realize cash tax benefits in future periods. Effective Tax Rate Our effective income tax rate from continuing operations for the first quarter of 2013 was 34.7% compared with 26.9% in the same period of the prior year. The effective tax rate in the first quarter of 2012 was favorably impacted by a tax benefit of $5 million (10.4% of earnings before tax) relating to the favorable resolution of a tax item from prior periods.

Uncertain Tax Positions

We are subject to tax audits in numerous jurisdictions in the U.S. and foreign countries. Tax audits by their very nature are often complex and can require several years to complete. In the normal course of business, we are subject to challenges from the Internal Revenue Service (IRS) and other tax authorities regarding amounts of taxes due. These challenges may alter the timing or amount of taxable income or deductions, or the allocation of income among tax jurisdictions. As part of our calculation of the provision for income taxes on earnings, we recognize the tax benefit from uncertain tax positions that are at least more likely than not of being sustained upon audit based on the technical merits of the tax position. The tax benefit to be recognized is measured as the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. Such calculations require management to make estimates and judgments with respect to the ultimate outcome of a tax audit. Actual results could vary materially from these estimates. We reevaluate uncertain tax positions each quarter based on factors including, but not limited to, changes in facts or circumstances, expiration of statutes of limitations, changes in tax law, effectively settled issues under audit, and new audit activity. Depending on the jurisdiction, such a change in recognition or measurement may result in the recognition of a tax benefit or an additional charge to the tax provision in the period.

The following is a summary of tax years that are no longer subject to examination:

Federal — audits of our U.S. federal income tax returns are closed through fiscal year 2008.

Foreign — we are no longer subject to foreign tax examinations by tax authorities for tax years before 2005 in Canada, 2006 in Brazil, 2008 in Mexico and 2010 in the U.K., which are our major foreign tax jurisdictions.
