The fourth quarter of 2013 includes a reduction in bad debt expense of $17 as compared to the fourth quarter of 2012 primarily due to improved receivable aging. In the fourth quarter of 2013, we recognized a benefit of $3 in cost of equipment rentals, excluding depreciation related to our provision for self-insurance reserves.

[2]

During the fourth quarter of 2012, we recognized $13 of charges associated with the RSC acquisition. Additionally, during the quarter, we recognized restructuring charges of $6, primarily reflecting branch closure charges associated with the RSC acquisition. During the quarter, we also recognized asset impairment charges of $2 which are primarily reflected in non-rental depreciation and amortization and principally relate to write-offs of leasehold improvements and other fixed assets. During the fourth quarter of 2012, we redeemed our 10 7/8 percent Senior Notes and all of our outstanding 1 7/8 percent Convertible Senior Subordinated Notes were converted. Upon redemption/conversion, we recognized a loss of $72 in interest expense, net. The loss represents the difference between the net carrying amount and the total purchase/conversion price of these securities. During the quarter, we also recognized a benefit of $6 in cost of equipment rentals, excluding depreciation related to our provision for self-insurance reserves. Additionally, operating income for the fourth quarter 2012 included $8 of costs, in the aggregate, primarily related to the merger, which should have been recognized in the second and third quarters of 2012. There was no impact on 2012 full year operating income.

There were no material reclassifications from accumulated other comprehensive income reflected in other comprehensive income (loss) during the years ended December 31, 2013, 2012 or 2011. There is no tax impact related to the foreign currency translation adjustments, as the earnings are considered permanently reinvested. There were no material taxes associated with other comprehensive income (loss) during the years ended December 31, 2013, 2012 or 2011.

[1]	The fourth quarter of 2013 includes a reduction in bad debt expense of $17 as compared to the fourth quarter of 2012 primarily due to improved receivable aging. In the fourth quarter of 2013, we recognized a benefit of $3 in cost of equipment rentals, excluding depreciation related to our provision for self-insurance reserves.
[2]	During the fourth quarter of 2012, we recognized $13 of charges associated with the RSC acquisition. Additionally, during the quarter, we recognized restructuring charges of $6, primarily reflecting branch closure charges associated with the RSC acquisition. During the quarter, we also recognized asset impairment charges of $2 which are primarily reflected in non-rental depreciation and amortization and principally relate to write-offs of leasehold improvements and other fixed assets. During the fourth quarter of 2012, we redeemed our 10 7/8 percent Senior Notes and all of our outstanding 1 7/8 percent Convertible Senior Subordinated Notes were converted. Upon redemption/conversion, we recognized a loss of $72 in interest expense, net. The loss represents the difference between the net carrying amount and the total purchase/conversion price of these securities. During the quarter, we also recognized a benefit of $6 in cost of equipment rentals, excluding depreciation related to our provision for self-insurance reserves. Additionally, operating income for the fourth quarter 2012 included $8 of costs, in the aggregate, primarily related to the merger, which should have been recognized in the second and third quarters of 2012. There was no impact on 2012 full year operating income.

	Organization, Description of Business and Consolidation
	United Rentals, Inc. ("Holdings") is principally a holding company and conducts its operations primarily through its wholly owned subsidiary, United Rentals (North America), Inc. (“URNA”), and subsidiaries of URNA. Holdings’ primary asset is its sole ownership of all issued and outstanding shares of common stock of URNA. URNA’s various credit agreements and debt instruments place restrictions on its ability to transfer funds to its stockholder. As used in this report, the terms the “Company,” “United Rentals,” “we,” “us,” and “our” refer to United Rentals, Inc. and its subsidiaries, unless otherwise indicated.
	We rent equipment to a diverse customer base that includes construction and industrial companies, manufacturers, utilities, municipalities, homeowners and others in the United States and Canada. In addition to renting equipment, we sell new and used rental equipment, as well as related contractor supplies, parts and service.
	The accompanying consolidated financial statements include our accounts and those of our controlled subsidiary companies. All significant intercompany accounts and transactions have been eliminated. We consolidate variable interest entities if we are deemed the primary beneficiary of the entity. Certain reclassifications of prior years’ amounts have been made to conform to the current year’s presentation.

	Summary of Significant Accounting Policies
	Cash Equivalents
	We consider all highly liquid instruments with maturities of three months or less when purchased to be cash equivalents. Our cash equivalents at December 31, 2013 consist of direct obligations of financial institutions rated A or better.
	Allowance for Doubtful Accounts
	We maintain allowances for doubtful accounts. These allowances reflect our estimate of the amount of our receivables that we will be unable to collect based on historical write-off experience. Our estimate could require change based on changing circumstances, including changes in the economy or in the particular circumstances of individual customers. Accordingly, we may be required to increase or decrease our allowances. Trade receivables that have contractual maturities of one year or less are written-off when they are determined to be uncollectible based on the criteria necessary to qualify as a deduction for federal tax purposes. Write-offs of such receivables require management approval based on specified dollar thresholds.
	Inventory
	Inventory consists of new equipment, contractor supplies, tools, parts, fuel and related supply items. Inventory is stated at the lower of cost or market. Cost is determined, depending on the type of inventory, using either a specific identification, weighted-average or first-in, first-out method.
	Rental Equipment
	Rental equipment, which includes service and delivery vehicles, is recorded at cost and depreciated over the estimated useful life of the equipment using the straight-line method. The range of estimated useful lives for rental equipment is two to 12 years. Rental equipment is depreciated to a salvage value of zero to 10 percent of cost. Rental equipment is depreciated whether or not it is out on rent. Costs we incur in connection with refurbishment programs that extend the life of our equipment are capitalized and amortized over the remaining useful life of the equipment. The costs incurred under these refurbishment programs were $44, $24 and $10 for the years ended December 31, 2013, 2012 and 2011, respectively, and are included in purchases of rental equipment in our consolidated statements of cash flows. Ordinary repair and maintenance costs are charged to operations as incurred. Repair and maintenance costs are included in cost of revenues on our consolidated statements of income. Repair and maintenance expense (including both labor and parts) for our rental equipment was $563, $455 and $291 for the years ended December 31, 2013, 2012 and 2011, respectively.
	Property and Equipment
	Property and equipment are recorded at cost and depreciated over their estimated useful lives using the straight-line method. The range of estimated useful lives for property and equipment is two to 39 years. Ordinary repair and maintenance costs are charged to expense as incurred. Leasehold improvements are amortized using the straight-line method over their estimated useful lives or the remaining life of the lease, whichever is shorter.
	Purchase Price Allocation
	We have made a number of acquisitions in the past (including the acquisition of RSC Holdings Inc. (“RSC”) in 2012) and may continue to make acquisitions in the future. We allocate the cost of the acquired entity to the assets acquired and liabilities assumed based on their respective fair values at the date of acquisition. Long lived assets (principally rental equipment), goodwill and other intangible assets generally represent the largest components of our acquisitions. The intangible assets that we have acquired are non-compete agreements, customer relationships and trade names and associated trademarks. Goodwill is calculated as the excess of the cost of the acquired entity over the net of the fair value of the assets acquired and the liabilities assumed. Non-compete agreements, customer relationships and trade names and associated trademarks are valued based on an excess earnings or income approach based on projected cash flows.
	When we make an acquisition, we also acquire other assets and assume liabilities. These other assets and liabilities typically include, but are not limited to, parts inventory, accounts receivable, accounts payable and other working capital items. Because of their short-term nature, the fair values of these other assets and liabilities generally approximate the book values on the acquired entities' balance sheets.
	Evaluation of Goodwill Impairment
	Goodwill is tested for impairment annually or more frequently if an event or circumstance indicates that an impairment loss may have been incurred. Application of the goodwill impairment test requires judgment, including: the identification of reporting units; assignment of assets and liabilities to reporting units; assignment of goodwill to reporting units; determination of the fair value of each reporting unit; and an assumption as to the form of the transaction in which the reporting unit would be acquired by a market participant (either a taxable or nontaxable transaction).
	We estimate the fair value of our reporting units (which are our regions) using a combination of an income approach based on the present value of estimated future cash flows and a market approach based on market price data of shares of our Company and other corporations engaged in similar businesses as well as acquisition multiples paid in recent transactions within our industry (including our own acquisitions). We believe this approach, which utilizes multiple valuation techniques, yields the most appropriate evidence of fair value. We review goodwill for impairment utilizing a two-step process. The first step of the impairment test requires a comparison of the fair value of each of our reporting units' net assets to the respective carrying value of net assets. If the carrying value of a reporting unit's net assets is less than its fair value, no indication of impairment exists and a second step is not performed. If the carrying amount of a reporting unit's net assets is higher than its fair value, there is an indication that an impairment may exist and a second step must be performed. In the second step, the impairment is calculated by comparing the implied fair value of the reporting unit's goodwill (as if purchase accounting were performed on the testing date) with the carrying amount of the goodwill. If the carrying amount of the reporting unit's goodwill is greater than the implied fair value of its goodwill, an impairment loss must be recognized for the excess and charged to operations.
	Financial Accounting Standards Board ("FASB") guidance permits entities to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test.
	In connection with our goodwill impairment test that was conducted as of October 1, 2012, we bypassed the qualitative assessment for each of our reporting units and proceeded directly to the first step of the goodwill impairment test. Our goodwill impairment testing as of this date indicated that all of our reporting units had estimated fair values which exceeded their respective carrying amounts by at least 15 percent.
	In connection with our goodwill impairment test that was conducted as of October 1, 2013, we performed the following procedures:
	Qualitative assessment: For 10 of our reporting units, which had combined goodwill of $2.3 billion as of October 1, 2013, we concluded that it was more likely than not that the fair values of our reporting units were greater than their carrying amounts. After reaching this conclusion, no further testing was performed. The qualitative factors we considered included, but were not limited to, general economic conditions, our outlook for construction activity, our recent and forecasted financial performance and the price of the Company's common stock;
	Impairment test: In 2013, there was a change in our internal reporting structure that impacted four of our regions: Trench Safety, Power and HVAC, Pacific West and Western Canada. As a result of this realignment, for these regions, which had combined goodwill of $626 as of October 1, 2013, we bypassed the qualitative assessment and proceeded directly to the first step of the goodwill impairment test. Our goodwill impairment testing as of this date indicated that each of these reporting units had estimated fair values which exceeded their respective carrying amounts by at least 44 percent.
	Restructuring Charges
	Costs associated with exit or disposal activities, including lease termination costs and certain employee severance costs associated with restructuring, branch closing or other activity, are recognized at fair value when they are incurred.
	Other Intangible Assets
	Other intangible assets consist of non-compete agreements, customer relationships and trade names and associated trademarks. The non-compete agreements are being amortized on a straight-line basis over initial periods of approximately 5 years. The customer relationships are being amortized either using the sum of the years' digits method or on a straight-line basis over initial periods ranging from 8 to 15 years. The trade names and associated trademarks are being amortized using the sum of the years' digits method over an initial period of 5 years. We believe that the amortization methods used reflect the estimated pattern in which the economic benefits will be consumed.
	Long-Lived Assets
	Long-lived assets are recorded at the lower of amortized cost or fair value. As part of an ongoing review of the valuation of long-lived assets, we assess the carrying value of such assets if facts and circumstances suggest they may be impaired. If this review indicates the carrying value of such an asset may not be recoverable, as determined by an undiscounted cash flow analysis over the remaining useful life, the carrying value would be reduced to its estimated fair value.
	Translation of Foreign Currency
	Assets and liabilities of our Canadian subsidiaries that have a functional currency other than U.S. dollars are translated into U.S. dollars using exchange rates at the balance sheet date. Revenues and expenses are translated at average exchange rates effective during the year. Foreign currency translation gains and losses are included as a component of accumulated other comprehensive income within stockholders’ equity.
	Revenue Recognition
	Our rental contract periods are hourly, daily, weekly or monthly and we recognize equipment rental revenue on a straight-line basis. As part of this straight-line methodology, when the equipment is returned, we recognize as incremental revenue the excess, if any, between the amount the customer is contractually required to pay over the cumulative amount of revenue recognized to date. We record amounts billed to customers in excess of recognizable revenue as deferred revenue on our balance sheet. We had deferred revenue of $30 and $26 as of December 31, 2013 and 2012, respectively. Revenues from the sale of rental equipment and new equipment are recognized at the time of delivery to, or pick-up by, the customer and when collectibility is reasonably assured. Sales of contractor supplies are also recognized at the time of delivery to, or pick-up by, the customer. Service revenue is recognized as the services are performed. Sales tax amounts collected from customers are recorded on a net basis.
	Delivery Expense
	Equipment rentals include our revenues from fees we charge for equipment delivery. Delivery costs are charged to operations as incurred, and are included in cost of revenues on our consolidated statements of income.
	Advertising Expense
	We promote our business through local and national advertising in various media, including trade publications, yellow pages, the Internet, radio and direct mail. Advertising costs are generally expensed as incurred. Advertising expense, net of qualified advertising reimbursements, was $0 for each of the years ended December 31, 2013, 2012 and 2011.
	Insurance
	We are insured for general liability, workers’ compensation and automobile liability, subject to deductibles or self-insured retentions per occurrence of $2 for general liability, $1 for workers’ compensation and $2 for automobile liability as of December 31, 2013 and 2012. Losses within these deductible amounts are accrued based upon the aggregate liability for reported claims incurred, as well as an estimated liability for claims incurred but not yet reported. These liabilities are not discounted. The Company is also self-insured for group medical claims but purchases “stop loss” insurance to protect itself from any one loss exceeding $600,000 (actual dollars).
	Income Taxes
	We use the liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on the differences between financial statement and tax bases of assets and liabilities and are measured using the tax rates and laws that are expected to be in effect when the differences are expected to reverse. Recognition of deferred tax assets is limited to amounts considered by management to be more likely than not to be realized in future periods. The most significant positive evidence that we consider in the recognition of deferred tax assets is the expected reversal of cumulative deferred tax liabilities resulting from book versus tax depreciation of our rental equipment fleet that is well in excess of the deferred tax assets.
	We use a two-step approach for recognizing and measuring tax benefits taken or expected to be taken in a tax return regarding uncertainties in income tax positions. The first step is recognition: we determine whether it is more likely than not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. In evaluating whether a tax position has met the more-likely-than-not recognition threshold, we presume that the position will be examined by the appropriate taxing authority with full knowledge of all relevant information. The second step is measurement: a tax position that meets the more-likely-than-not recognition threshold is measured to determine the amount of benefit to recognize in the financial statements. The tax position is measured at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. Differences between tax positions taken in a tax return and amounts recognized in the financial statements will generally result in one or more of the following: an increase in a liability for income taxes payable, a reduction of an income tax refund receivable, a reduction in a deferred tax asset or an increase in a deferred tax liability.
	Use of Estimates
	The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Significant estimates impact the calculation of the allowance for doubtful accounts, depreciation and amortization, income taxes, reserves for claims, loss contingencies (including legal contingencies) and the fair values of financial instruments. Actual results could materially differ from those estimates.
	Concentrations of Credit Risk
	Financial instruments that potentially subject us to significant concentrations of credit risk include cash and cash equivalents and accounts receivable. We maintain cash and cash equivalents with high quality financial institutions. Concentration of credit risk with respect to receivables is limited because a large number of geographically diverse customers make up our customer base. Our largest customer accounted for less than one percent of total revenues in each of 2013, 2012, and 2011. Our customer with the largest receivable balance represented approximately one percent and two percent of total receivables at December 31, 2013 and 2012, respectively. We manage credit risk through credit approvals, credit limits and other monitoring procedures.
	Stock-Based Compensation
	We measure stock-based compensation at the grant date based on the fair value of the award and recognize stock-based compensation expense over the requisite service period. Determining the fair value of stock option awards requires judgment, including estimating stock price volatility, forfeiture rates and expected option life. Restricted stock awards are valued based on the fair value of the stock on the grant date and the related compensation expense is recognized over the service period. Similarly, for time-based restricted stock awards subject to graded vesting, we recognize compensation cost on a straight-line basis over the requisite service period. We classify cash flows from tax benefits resulting from tax deductions in excess of the compensation cost recognized for stock-based awards (“excess tax benefits”) as financing cash flows.

Acquisitions	'
	Acquisitions
	On April 30, 2012 (“the acquisition date”), we acquired 100 percent of the outstanding common shares and voting interest of RSC. The results of RSC's operations have been included in our consolidated financial statements since the acquisition date. RSC, which had total revenues of $1.5 billion in 2011, was one of the largest equipment rental providers in North America, and had a network of 440 rental locations in 43 U.S. states and three Canadian provinces as of December 31, 2011. The acquisition has created a leading North American equipment rental company with a more attractive business mix, greater scale and enhanced growth prospects, and we believe that the acquisition will provide us with financial benefits including reduced operating expenses and additional revenue opportunities going forward.
	The acquisition date fair value of the consideration transferred of $2.6 billion consisted of the following:
	Cash consideration	$	1,161
	Stock consideration (30 million shares valued based on the URI acquisition date stock price)	1,396
	Share-based compensation awards (1)	29
	Total purchase consideration	$	2,586
	(1) This relates to RSC stock options and restricted stock units which were outstanding as of the acquisition date. Each RSC stock option was converted into an adjusted United Rentals stock option to acquire a number of shares of United Rentals common stock, determined by multiplying the number of shares of RSC common stock subject to the RSC stock option by the option exchange ratio (rounded down, if necessary, to a whole share of United Rentals common stock). The “option exchange ratio” means the sum of (i) 0.2783 and (ii) the quotient determined by dividing $10.80 by the volume-weighted average of the closing sale prices of shares of URI common stock as reported on the NYSE composite transactions reporting system for each of the 10 consecutive trading days ending with the acquisition date. The option exchange ratio was 0.5161. The exercise price per share of United Rentals common stock subject to the adjusted United Rentals option is equal to the per share exercise price of such RSC stock option divided by the option exchange ratio (rounded up, if necessary, to the nearest whole cent). Each RSC restricted stock unit (other than an award held by a member of the RSC board who was not also an employee or officer of RSC at such time) was converted into an adjusted United Rentals restricted stock unit in an amount determined by multiplying the number of shares of RSC common stock subject to the RSC restricted stock unit by the option exchange ratio. The portion of the United Rentals replacement awards that has been included in the purchase consideration was calculated as $29 and is based on the vesting which occurred prior to the acquisition date.
	The following table summarizes the fair values of the assets acquired and liabilities assumed as of the acquisition date.
	Accounts receivable, net of allowance for doubtful accounts (1)	$	238
	Inventory	23
	Deferred taxes	15
	Rental equipment	2,013
	Property and equipment	47
	Intangibles (2)	1,224
	Other assets	55
	Total identifiable assets acquired	3,615
	Short-term debt and current maturities of long-term debt (3)	(1,586		)
	Current liabilities	(400		)
	Deferred taxes	(696		)
	Long-term debt (3)	(992		)
	Other long-term liabilities	(13		)
	Total liabilities assumed	(3,687		)
	Net identifiable assets acquired	(72		)
	Goodwill (4)	2,658
	Net assets acquired	$	2,586
	(1) The fair value of accounts receivables acquired was $238, and the gross contractual amount was $251. We estimated that $13 will be uncollectible.
	(2) The following table reflects the estimated fair values and useful lives of the acquired intangible assets identified based on our purchase accounting assessments:
		Fair value			Life (years)
	Customer relationships	$	1,094		15
	Trade names and associated trademarks	81			5
	Non-compete agreements	49			5
	Total	$	1,224
	(3) At the closing of the merger, URNA repaid RSC's senior ABL facility, 10 percent senior notes, and 9.5 percent senior notes. The repaid debt is reflected as short-term above as it was paid on the acquisition date. The RSC debt reflected in our consolidated balance sheet as of December 31, 2013 is discussed further in note 12 to the consolidated financial statements. The debt in the table above includes $1,555 of the repaid RSC debt, and the fair values of the following debt assumed by URNA:
	10 1/4 percent Senior Notes	$	(225	)
	8 1/4 percent Senior Notes	(699		)
	Capital leases	(99		)
	Total assumed debt	$	(1,023	)
	(4) All of the goodwill was assigned to our general rentals segment. The level of goodwill that resulted from the merger is primarily reflective of RSC's going-concern value, the value of RSC's assembled workforce, new customer relationships expected to arise from the merger, and operational synergies that we expect to achieve that would not be available to other market participants. $39 of the goodwill is expected to be deductible for income tax purposes.
	The years ended December 31, 2013, 2012 and 2011include acquisition-related costs of $9, $111 and $19, respectively. The acquisition-related costs are reflected in our consolidated statements of income as “RSC merger related costs” and primarily relate to financial and legal advisory fees, and branding costs. The fees for the year ended December 31, 2012 include $31 of interim bridge financing costs. We do not expect to incur significant additional charges in connection with the merger subsequent to December 31, 2013. In addition to the acquisition-related costs reflected in our consolidated statements of income, we capitalized $67 of debt issuance costs associated with the issuance of debt to fund the acquisition, which are reflected, net of amortization subsequent to the acquisition date, in other long-term assets in our consolidated balance sheets.
	Since the acquisition date, significant amounts of fleet have been moved between legacy United Rentals locations and the acquired RSC locations, and it is not practicable to reasonably estimate the amounts of revenue and earnings of RSC since the acquisition date. The impact of the RSC acquisition on our equipment rentals revenue is primarily reflected in the increases in the volume of OEC on rent of 22.1 percent and 63.2 percent for the years ended December 31, 2013 and 2012, respectively.
	The pro forma information below has been prepared using the purchase method of accounting, giving effect to the RSC acquisition as if the acquisition had been completed on January 1, 2011 (“the pro forma acquisition date”). The pro forma information is not necessarily indicative of our results of operations had the merger been completed on the above date, nor is it necessarily indicative of our future results. The pro forma information does not reflect any cost savings from operating efficiencies or synergies that could result from the merger, and also does not reflect additional revenue opportunities following the merger. The pro forma information includes adjustments to give effect to the financing for the acquisition and related transactions. The table below presents unaudited pro forma consolidated income statement information as if RSC had been included in our consolidated results for the entire periods reflected:
		Year Ended December 31,
		2012				2011
	United Rentals historic revenues	$	4,117			$	2,611
	RSC historic revenues	547				1,522
	Pro forma revenues	4,664				4,133
	United Rentals historic pretax income	88				164
	RSC historic pretax loss	(8		)		(40		)
	Combined pretax income	80				124
	Pro forma adjustments to combined pretax income:
	Impact of fair value mark-ups/useful life changes on depreciation (1)	—				—
	Impact of the fair value mark-up of acquired RSC fleet on cost of rental equipment sales (2)	(4		)		(12		)
	Intangible asset amortization (3)	(43		)		(173		)
	Interest expense on merger financing notes (4)	(39		)		(207		)
	Elimination of historic RSC interest (5)	38				166
	RSC historic interest fair value adjustment (6)	2				7
	Elimination of merger costs (7)	148				30
	Restructuring charges (8)	92				(101		)
	Pro forma pretax income (loss)	$	274			$	(166	)
	(1) Depreciation of rental equipment and non-rental depreciation were adjusted for the fair value mark-ups of equipment acquired in the RSC acquisition, the impact of which was offset by the impact of extending the useful lives of such equipment.
	(2) Cost of rental equipment sales was adjusted for the fair value mark-ups of rental equipment acquired in the RSC acquisition.
	(3) The intangible assets acquired in the RSC acquisition were amortized.
(4) Interest expense was adjusted to reflect interest on the merger financing notes described in note 12 to the consolidated financial statements.
(5) RSC historic interest on debt that is not part of the combined entity was eliminated.
(6) RSC historic interest was adjusted for the fair value mark-ups of the debt acquired in the RSC acquisition.
(7) The RSC merger related costs were eliminated as they were assumed to have been recognized prior to the pro forma acquisition date.
(8) Restructuring charges comprised of severance costs and branch closure charges associated with the acquisition were recognized for 5 quarters (the period from the actual acquisition date through the end of the restructuring program) following the pro forma acquisition date. For the pro forma presentation, over 95 percent of the total charges are reflected in the first year following the pro forma acquisition date, which reflects the timing of the actual restructuring charges.
In addition to the acquisition of RSC, in February 2012, we completed the acquisition of Coble Trench Safety (”Coble”), a specialty rental company with 11 locations in the Mid-Atlantic and Southeast region. Coble had annual rental revenues of approximately $20. Additionally, in August 2013, we completed the acquisition of Rent World, an equipment rental company with two locations in Alberta, Canada. Rent World had annual rental revenues of approximately $5.

	Our reportable segments are general rentals and trench safety, power and HVAC (heating, ventilating and air conditioning). The general rentals segment includes the rental of the following equipment:
	•	General construction and industrial equipment, such as backhoes, skid-steer loaders, forklifts, earthmoving equipment and material handling equipment. In 2013, 2012 and 2011, respectively, general construction and industrial equipment accounted for approximately 44 percent, 45 percent and 41 percent of our equipment rental revenue;
	•	Aerial work platforms, such as boom lifts and scissor lifts. In 2013, 2012 and 2011, respectively, aerial work platforms accounted for approximately 36 percent, 36 percent and 39 percent of our equipment rental revenue; and
	•	General tools and light equipment, such as pressure washers, water pumps and power tools. In 2013, 2012 and 2011, respectively, general tools and light equipment accounted for approximately 9 percent, 9 percent and 8 percent of our equipment rental revenue.
	The general rentals segment reflects the aggregation of 12 geographic regions—Eastern Canada, Gulf South, Industrial (which serves the geographic Gulf region and has a strong industrial presence), Mid-Atlantic, Mid-Central, Midwest, Mountain West, Northeast, Pacific West, South, Southeast and Western Canada—and operates throughout the United States and Canada.
	The trench safety, power and HVAC segment includes the rental of specialty construction products such as the following:
	•	Power and HVAC equipment, such as portable diesel generators, electrical distribution equipment, and temperature control equipment. In 2013, 2012 and 2011, power and HVAC equipment accounted for approximately 6 percent of our equipment rental revenue; and
	•	Trench safety equipment, such as trench shields, aluminum hydraulic shoring systems, slide rails, crossing plates, construction lasers and line testing equipment for underground work. In 2013, 2012 and 2011, respectively, trench safety equipment accounted for approximately 5 percent, 4 percent and 6 percent of our equipment rental revenue.
	The trench safety, power and HVAC segment is comprised of the Trench Safety region, which rents the trench safety equipment above, and the Power and HVAC region, which rents the power and HVAC equipment above. The trench safety, power and HVAC segment’s customers include construction companies involved in infrastructure projects, municipalities and industrial companies. This segment operates throughout the United States and in Canada.
	These segments align our external segment reporting with how management evaluates business performance and allocates resources. We evaluate segment performance based on segment equipment rentals gross profit.
	The accounting policies for our segments are the same as those described in the summary of significant accounting policies in note 2. Certain corporate costs, including those related to selling, finance, legal, risk management, human resources, corporate management and information technology systems, are deemed to be of an operating nature and are allocated to our segments based primarily on rental fleet size.
	The following table sets forth financial information by segment for the years ended December 31, 2013, 2012 and 2011, except for balance sheet information, which is presented as of December 31, 2013 and 2012.

Restructuring and Asset Impairment Charges	'
	Restructuring and Asset Impairment Charges
	Closed Restructuring Program
	Over the past several years, we have been focused on reducing our operating costs. In connection with this strategy, and in recognition of the challenging economic environment, we reduced our employee headcount from approximately 10,900 at January 1, 2008 (the beginning of the restructuring period) to approximately 7,500 at December 31, 2011 (the end of the restructuring period). Additionally, we reduced our branch network from 697 locations at January 1, 2008 to 529 locations at December 31, 2011. The restructuring charges under the closed restructuring program for the years ended December 31, 2013, 2012 and 2011 include severance costs associated with headcount reductions, as well as branch closure charges which principally relate to continuing lease obligations at vacant facilities. We do not expect to incur significant additional charges in connection with the restructuring, which was complete as of December 31, 2011.
	The table below provides certain information concerning our restructuring charges under the closed restructuring program:

	Between January 1, 2008 and December 31, 2013, we incurred total restructuring charges under the closed restructuring program of $110, comprised of $89 of branch closure charges and $21 of severance costs.
	RSC Merger Related Restructuring Program
	In the second quarter of 2012, we initiated a restructuring program related to severance costs and branch closure charges associated with the RSC acquisition. The branch closure charges principally relate to continuing lease obligations at vacant facilities closed subsequent to the RSC acquisition. As of December 31, 2013, our employee headcount is approximately 11,850 and our branch network has 832 rental locations. We do not expect to incur significant additional charges in connection with the restructuring, which was complete as of June 30, 2013.
	The table below provides certain information concerning our restructuring charges under the RSC merger related restructuring program:

	Between January 1, 2012 and December 31, 2013, we incurred total restructuring charges under the RSC merger related restructuring program of $105, comprised of $60 of branch closure charges and $45 of severance costs.
	Asset Impairment Charges
	In addition to the restructuring charges discussed above, during the years ended December 31, 2013, 2012 and 2011, we recorded asset impairment charges of $4, $15 and $4, respectively, in our general rentals segment. The impairment charges are primarily reflected in non-rental depreciation and amortization in the accompanying consolidated statements of income and principally relate to write-offs of leasehold improvements and other fixed assets in connection with the restructuring activity discussed above.

Derivative Instruments and Hedging Activities Disclosure [Abstract]	'
Derivatives	'
	Derivatives
	We recognize all derivative instruments as either assets or liabilities at fair value, and recognize changes in the fair value of the derivative instruments based on the designation of the derivative. For derivative instruments that are designated and qualify as hedging instruments, we designate the hedging instrument, based upon the exposure being hedged, as either a fair value hedge or a cash flow hedge. As of December 31, 2013, we do not have any outstanding derivative instruments designated as fair value hedges. The effective portion of the changes in fair value of derivatives that are designated as cash flow hedges is recorded as a component of accumulated other comprehensive income. Amounts included in accumulated other comprehensive income for cash flow hedges are reclassified into earnings in the same period that the hedged item is recognized in earnings. The ineffective portion of changes in the fair value of derivatives designated as cash flow hedges is recorded currently in earnings. For derivative instruments that do not qualify for hedge accounting, we recognize gains or losses due to changes in fair value in our consolidated statements of income during the period in which the changes in fair value occur.
	We are exposed to certain risks relating to our ongoing business operations. During the year ended December 31, 2013, the risks we managed using derivative instruments were diesel price risk and foreign currency exchange rate risk. At December 31, 2013, we had outstanding fixed price swap contracts on diesel purchases which were entered into to mitigate the price risk associated with forecasted purchases of diesel. During the year ended December 31, 2013, we entered into forward contracts to purchase Canadian dollars to mitigate the foreign currency exchange rate risk associated with certain Canadian dollar denominated intercompany loans. At December 31, 2013, there were no outstanding forward contracts to purchase Canadian dollars. The outstanding forward contracts on diesel purchases were designated and qualify as cash flow hedges and the forward contracts to purchase Canadian dollars, which were all settled as of December 31, 2013, represented derivative instruments not designated as hedging instruments.
	Fixed Price Diesel Swaps
	The fixed price swap contracts on diesel purchases that were outstanding at December 31, 2013 were designated and qualify as cash flow hedges and the effective portion of the unrealized gain or loss on these contracts is reported as a component of accumulated other comprehensive income and is reclassified into earnings in the period during which the hedged transaction affects earnings (i.e., when the hedged gallons of diesel are used). The remaining gain or loss on the fixed price swap contracts in excess of the cumulative change in the present value of future cash flows of the hedged item, if any (i.e., the ineffective portion), is recognized in our consolidated statements of income during the current period. As of December 31, 2013, we had outstanding fixed price swap contracts covering 6.9 million gallons of diesel which will be purchased throughout 2014.
	Foreign Currency Forward Contracts
	The forward contracts to purchase Canadian dollars, which were all settled as of December 31, 2013, represented derivative instruments not designated as hedging instruments and gains or losses due to changes in the fair value of the forward contracts were recognized in our consolidated statements of income during the period in which the changes in fair value occurred. During the year ended December 31, 2013, forward contracts were used to purchase $421 Canadian dollars, representing the total amount due at maturity for certain Canadian dollar denominated intercompany loans that were settled during the year ended December 31, 2013. Upon maturity, the proceeds from the forward contracts were used to pay down the Canadian dollar denominated intercompany loans.
	Financial Statement Presentation
	As of December 31, 2013 and December 31, 2012, $1 and less than $1 were reflected in prepaid expenses and other assets, respectively, less than $1 was reflected in accrued expenses and other liabilities, and less than $1 was reflected in accumulated other comprehensive income in our consolidated balance sheets associated with the outstanding fixed price swap contracts that were designated and qualify as cash flow hedges. Operating cash flows in our consolidated statement of cash flows for the year ended December 31, 2013 include $38 associated with the fixed price diesel swaps, comprised of the $38 cost of the 9.7 million hedged gallons of diesel purchased in 2013, net of cash received from the counterparties to the fixed price swaps. Insignificant amounts (less than $1) were reflected in our consolidated statement of cash flows for the year ended December 31, 2013 associated with the forward contracts to purchase Canadian dollars. Operating cash flows in our consolidated statement of cash flows for the year ended December 31, 2012 include $25 associated with the fixed price diesel swaps, comprised of the $25 cost of the 6.3 million hedged gallons of diesel purchased in 2012, net of cash received from the counterparties to the fixed price swaps. Insignificant amounts (less than $1) were reflected in our consolidated statement of cash flows for the year ended December 31, 2012 associated with the forward contracts to purchase Canadian dollars. Operating cash flows in our consolidated statement of cash flows for the year ended December 31, 2011 include $22 associated with the fixed price diesel swaps, comprised of the $23 cost of the 5.9 million hedged gallons of diesel purchased in 2011, net of cash received from the counterparty to the fixed price swaps. Insignificant amounts (less than $1) were reflected in our consolidated statement of cash flows for the year ended December 31, 2011 associated with the forward contracts to purchase Canadian dollars, as the cash impact of the $4 gain recognized on the derivative was offset by the $4 loss recognized on the hedged item.

Fair Value Disclosures [Abstract]	'
Fair Value Measurements	'
	Fair Value Measurements
	We account for certain assets and liabilities at fair value, and categorize each of our fair value measurements in one of the following three levels based on the lowest level input that is significant to the fair value measurement in its entirety:
	Level 1—Inputs to the valuation methodology are unadjusted quoted prices in active markets for identical assets or liabilities.
	Level 2—Observable inputs other than quoted prices in active markets for identical assets and liabilities include:
	a) quoted prices for similar assets or liabilities in active markets;
	b) quoted prices for identical or similar assets or liabilities in inactive markets;
	c) inputs other than quoted prices that are observable for the asset or liability;
	d) inputs that are derived principally from or corroborated by observable market data by correlation or other means.
	If the asset or liability has a specified (contractual) term, the Level 2 input must be observable for substantially the full term of the asset or liability.
	Level 3—Inputs to the valuation methodology are unobservable (i.e., supported by little or no market activity) and significant to the fair value measure.
	Assets and Liabilities Measured at Fair Value
	As of December 31, 2013 and 2012, our only assets and liabilities measured at fair value were our fixed price diesel swaps contracts, which are Level 2 derivatives measured at fair value on a recurring basis. As of December 31, 2013, less than $1 was reflected in accrued expenses and other liabilities and $1 was reflected in prepaid expenses and other assets in our consolidated balance sheets, reflecting the fair values of the fixed price diesel swaps contracts. As of December 31, 2012, less than $1 was reflected in accrued expenses and other liabilities and less than $1 was reflected in prepaid expenses and other assets in our consolidated balance sheets reflecting the fair value of the fixed price diesel swaps contracts. As discussed in note 10 to the consolidated financial statements, we entered into the fixed price swap contracts on diesel purchases to mitigate the price risk associated with forecasted purchases of diesel. Fair value is determined based on observable market data. As of December 31, 2013, we have fixed price swap contracts covering 6.9 million gallons of diesel which we will buy throughout 2014 at the average contract price of $3.89 per gallon, while the average forward price for the hedged gallons was $3.98 per gallon as of December 31, 2013.

	The carrying amounts reported in our consolidated balance sheets for accounts receivable, accounts payable and accrued expenses and other liabilities approximate fair value due to the immediate to short-term maturity of these financial instruments. The fair values of our senior secured asset-based revolving credit facility (“ABL facility”) and accounts receivable securitization facility approximate their book values as of December 31, 2013 and 2012. The estimated fair values of our other financial instruments at December 31, 2013 and 2012 have been calculated based upon available market information or an appropriate valuation technique, and are as follows:
		December 31, 2013				December 31, 2012
		Carrying		Fair		Carrying		Fair
		Amount		Value		Amount		Value
	Level 1:
	Subordinated convertible debentures	$	—	$	—	$	55	$	63
	Senior and senior subordinated notes	5,381		5,848		5,387		5,881
	Level 2:
	4 percent Convertible Senior Notes (1)	136		149		137		155
	Level 3:
	Capital leases (2)	120		118		148		145
	-1	The fair value of the 4 percent Convertible Senior Notes is based on the market value of comparable notes. Consistent with the carrying amount, the fair value excludes the equity component of the notes. To exclude the equity component and calculate the fair value, we used an effective interest rate of 6.6 percent. As discussed below (see note 12), the total cost to settle the notes based on the closing price of our common stock on December 31, 2013 would be $1,094.
	-2	The fair value of capital leases reflects the present value of the leases using a 7.0 percent interest rate.

	-1	$1,142 and $53 were available under our ABL facility and accounts receivable securitization facility, respectively, at December 31, 2013. The ABL facility availability is reflected net of $52 of letters of credit. At December 31, 2013, the interest rates applicable to our ABL facility and accounts receivable securitization facility were 2.5 percent and 0.8 percent, respectively.
	-2	In connection with the RSC merger, on March 9, 2012, we issued the merger financing notes. See below for additional detail regarding each of the merger financing notes.
	-3	Upon consummation of the RSC merger, we assumed certain of RSC's debt, including capital leases. See below for additional detail regarding the assumed RSC debt.
	-4	In August 1998, a subsidiary trust of Holdings (the “Trust”) issued and sold $300 of 6 1/2 percent Convertible Quarterly Income Preferred Securities (“QUIPS”) in a private offering. The Trust used the proceeds from the offering to purchase 6 1/2 percent subordinated convertible debentures due 2028 (the “Debentures”), which resulted in Holdings receiving all of the net proceeds of the offering. The QUIPS were non-voting securities, carried a liquidation value of $50 (fifty dollars) per security and were convertible into Holdings’ common stock. During the year ended December 31, 2013, an aggregate of $55 of QUIPS was redeemed. In connection with these redemptions, during the year ended December 31, 2013, we retired $55 principal amount of our subordinated convertible debentures. As of December 31, 2013, there were no QUIPS or subordinated convertible debentures outstanding. Total long-term debt at December 31, 2012 excludes $55 of these Debentures, which were separately classified in our consolidated balance sheets and referred to as “subordinated convertible debentures.” The subordinated convertible debentures reflected the obligation to our subsidiary that issued the QUIPS. This subsidiary was not consolidated in our financial statements because we were not the primary beneficiary of the Trust. As of December 31, 2013, the Trust was liquidated.
	Short-term debt
	As of December 31, 2013, our short-term debt primarily reflects $430 of borrowings under our accounts receivable securitization facility and $136 of 4 percent Convertible Senior Notes. The 4 percent Convertible Senior Notes mature in 2015, but are reflected as short-term debt because they were redeemable at December 31, 2013. As discussed below, in 2013, we amended our accounts receivable securitization facility. During the year ended December 31, 2013, the monthly average amount outstanding under the accounts receivable securitization facility, including the former and amended facilities, was $450 and the weighted-average interest rate thereon was 0.8 percent. The maximum month-end amount outstanding under the accounts receivable securitization facility during the year ended December 31, 2013, including the former and amended facilities, was $494.
	Accounts Receivable Securitization Facility. In February and September 2013, we amended and renewed our accounts receivable securitization facility. The amended facility expires on September 18, 2014, includes an increase in the facility size from $475 to $550, and may be extended on a 364-day basis by mutual agreement of the Company and the lenders under the facility. Borrowings under the facility are reflected as short-term debt on our consolidated balance sheets. Key provisions of the facility include the following:
	•	borrowings are permitted only to the extent that the face amount of the receivables in the collateral pool, net of applicable reserves, exceeds the outstanding loans by a specified amount. As of December 31, 2013, there were $501 of receivables, net of applicable reserves, in the collateral pool;
	•	the receivables in the collateral pool are the lenders’ only source of repayment;
	•	upon early termination of the facility, no new amounts will be advanced under the facility and collections on the receivables securing the facility will be used to repay the outstanding borrowings; and
	•	standard termination events including, without limitation, a change of control of Holdings, URNA or certain of its subsidiaries, a failure to make payments, a failure to comply with standard default, delinquency, dilution and days sales outstanding covenants, or breach of certain financial ratio covenants under the ABL facility.
	ABL Facility. In June 2008, Holdings, URNA, and certain of our subsidiaries entered into a credit agreement providing for a five-year $1.25 billion ABL facility, a portion of which is available for borrowing in Canadian dollars. The ABL facility was subsequently upsized and extended, and in December 2013, the size of the facility was increased again to $2.3 billion. In June 2013, the ABL facility was amended to reduce the minimum borrowing period and to increase the number of available loan tranches.
	The ABL facility is subject to, among other things, the terms of a borrowing base derived from the value of eligible rental equipment and eligible inventory. The borrowing base is subject to certain reserves and caps customary for financings of this type. All amounts borrowed under the credit agreement must be repaid on or before October 2016. Loans under the credit agreement bear interest, at URNA’s option: (i) in the case of loans in U.S. dollars, at a rate equal to the London interbank offered rate or an alternate base rate, in each case plus a spread, or (ii) in the case of loans in Canadian dollars, at a rate equal to the Canadian prime rate or an alternate rate (Bankers Acceptance Rate), in each case plus a spread. The interest rates under the credit agreement are subject to change based on the availability in the facility. A commitment fee accrues on any unused portion of the commitments under the credit agreement at a rate per annum based on usage. Ongoing extensions of credit under the credit agreement are subject to customary conditions, including sufficient availability under the borrowing base. The credit agreement also contains covenants that, unless certain financial and other conditions are satisfied, require URNA to satisfy various financial tests and to maintain certain financial ratios. As discussed below (see “Loan Covenants and Compliance”), the only material financial covenants which currently exist relate to the fixed charge coverage ratio and the senior secured leverage ratio. Since an October 2011 amendment of the facility and through December 31, 2013, availability under the ABL facility has exceeded the required threshold and, as a result, these maintenance covenants have been inapplicable. In addition, the credit agreement contains customary negative covenants applicable to Holdings, URNA and our subsidiaries, including negative covenants that restrict the ability of such entities to, among other things, (i) incur additional indebtedness or engage in certain other types of financing transactions, (ii) allow certain liens to attach to assets, (iii) repurchase, or pay dividends or make certain other restricted payments on capital stock and certain other securities, (iv) prepay certain indebtedness and (v) make acquisitions and investments. The U.S. dollar borrowings under the credit agreement are secured by substantially all of our assets and substantially all of the assets of certain of our U.S. subsidiaries (other than real property and certain accounts receivable). The U.S. dollar borrowings under the credit agreement are guaranteed by Holdings and by URNA and, subject to certain exceptions, our domestic subsidiaries. Borrowings under the credit agreement by URNA’s Canadian subsidiaries are also secured by substantially all the assets of URNA’s Canadian subsidiaries and supported by guarantees from the Canadian subsidiaries and from Holdings and URNA, and, subject to certain exceptions, our domestic subsidiaries. Under the ABL facility, a change of control (as defined in the credit agreement) constitutes an event of default, entitling our lenders, among other things, to terminate our ABL facility and to require us to repay outstanding borrowings.
	As of December 31, 2013, the ABL facility was our only long-term variable rate debt instrument. During the year ended December 31, 2013, the monthly average amount outstanding under the ABL facility, including the former and amended facilities, was $1,187, and the weighted-average interest rate thereon was 2.3 percent. The maximum month-end amount outstanding under the ABL facility during the year ended December 31, 2013, including the former and amended facilities, was $1,478.
	9  1/4 percent Senior Notes. In November 2009, URNA issued $500 aggregate principal amount of 9 1/4  percent Senior Notes (the “9 1/4 percent Notes”), which are due December 15, 2019. The net proceeds from the sale of the 9 1/4 percent Notes were $480 (after deducting the initial purchasers’ discount and offering expenses). The 9 1/4 percent Notes are unsecured and are guaranteed by Holdings and, subject to limited exceptions, URNA’s domestic subsidiaries. The 9 1/4 percent Notes may be redeemed on or after December 15, 2014 at specified redemption prices that range from 104.625 percent in 2014 to 100.0 percent in 2017 and thereafter. The indenture governing the 9 1/4 percent Notes contains certain restrictive covenants, including, among others, limitations on (i) indebtedness; (ii) restricted payments; (iii) liens; (iv) asset sales; (v) issuance of preferred stock of restricted subsidiaries; (vi) transactions with affiliates; (vii) dividend and other payment restrictions affecting restricted subsidiaries; (viii) designations of unrestricted subsidiaries; (ix) additional subsidiary guarantees and (x) mergers, consolidations or sales of substantially all of its assets. The indenture also requires that, in the event of a change of control (as defined in the indenture), URNA must make an offer to purchase all of the then outstanding 9 1/4 percent Notes tendered at a purchase price in cash equal to 101 percent of the principal amount thereof plus accrued and unpaid interest, if any, thereon. The difference between the December 31, 2011 carrying value of the 9 1/4 percent Notes and the $500 principal amount relates to the $6 unamortized portion of the original issue discount recognized in conjunction with the issuance of these notes, which is being amortized through the above maturity date. The effective interest rate on the 9 1/4 percent Notes is 9.50 percent.
	8 3/8 percent Senior Subordinated Notes. In October 2010, URNA issued $750 aggregate principal amount of 8 3/8 percent Senior Subordinated Notes (the “8 3/8 percent Notes”), which are due September 15, 2020. The net proceeds from the sale of the 8 3/8 percent Notes were $732 (after deducting the initial purchasers’ discount and offering expenses). The 8 3/8 percent Notes are unsecured and are guaranteed by Holdings and, subject to limited exceptions, URNA’s domestic subsidiaries. The 8 3/8  percent Notes may be redeemed by URNA on or after September 15, 2015, at specified redemption prices that range from 104.188 percent in 2015 to 100.0 percent in 2018 and thereafter. The indenture governing the 8 3/8 percent Notes contains certain restrictive covenants, including, among others, limitations on (i) additional indebtedness, (ii) restricted payments, (iii) liens, (iv) asset sales, (v) preferred stock of certain subsidiaries, (vi) transactions with affiliates, (vii) dividends and other payments, (viii) designations of unrestricted subsidiaries; (ix) additional subsidiary guarantees; and (x) mergers, consolidations or sales of substantially all of our assets. The indenture also requires that, in the event of a change of control (as defined in the indenture), URNA must make an offer to purchase all of the then outstanding 8 3/8 percent Notes tendered at a purchase price in cash equal to 101 percent of the principal amount thereof plus accrued and unpaid interest, if any, thereon.
	6 1/8 percent Senior Notes. In October 2012, URNA issued $400 aggregate principal amount of 6 1/8 percent Senior Notes (the “6 1/8 percent Notes”), which are due June 15, 2023. The net proceeds from the sale of the 6 1/8 percent Notes were $392 (after deducting offering expenses). The 6 1/8 percent Notes are unsecured and are guaranteed by Holdings and, subject to limited exceptions, URNA's domestic subsidiaries. The 6 1/8 percent Notes may be redeemed by URNA on or after December 15, 2017, at specified redemption prices that range from 103.063 percent in 2017 to 100 percent in 2020 and thereafter. The indenture governing the 6 1/8 percent Notes contains certain restrictive covenants, including, among others, limitations on (i) additional indebtedness, (ii) restricted payments, (iii) liens, (iv) asset sales, (v) preferred stock of certain subsidiaries, (vi) transactions with affiliates, (vii) dividends and other payments, (viii) designations of unrestricted subsidiaries; (ix) additional subsidiary guarantees; and (x) mergers, consolidations or sales of substantially all of our assets. The indenture also requires that, in the event of a change of control (as defined in the indenture), URNA must make an offer to purchase all of the then outstanding 6 1/8 percent Notes tendered at a purchase price in cash equal to 101 percent of the principal amount thereof plus accrued and unpaid interest, if any, thereon.
	4 percent Convertible Senior Notes. In November 2009, Holdings issued $173 aggregate principal amount of unsecured 4 percent Convertible Senior Notes (the “4 percent Convertible Notes”), which are due November 15, 2015. The net proceeds from the sale of the 4 percent Convertible Notes were approximately $167, after commissions, fees and expenses, but before the $26 cost of the convertible note hedge transactions described below. Holders of the 4 percent Convertible Notes may convert them into shares of Holdings’ common stock prior to the close of business on the business day immediately preceding May 15, 2015 (subject to earlier conversion in certain circumstances) at an initial conversion price of approximately $11.11 per share of common stock (subject to further adjustment in certain circumstances), if (i) the price of Holdings’ common stock reaches a specific threshold, (ii) the trading price of the 4 percent Convertible Notes falls below certain thresholds or (iii) specified corporate transactions occur. The difference between the December 31, 2013 carrying value of the 4 percent Convertible Notes and the outstanding principal amount of $156 reflects the $20 unamortized portion of the original issue discount recognized upon issuance of the notes, which is being amortized through the maturity date of November 15, 2015. Because the 4 percent Convertible Notes were redeemable at December 31, 2013, an amount equal to the $20 unamortized portion of the original issue discount is separately classified in our consolidated balance sheets and referred to as “temporary equity.” Based on the price of our common stock during the fourth quarter of 2013, holders of the 4 percent Convertible Notes have the right to redeem the notes during the first quarter of 2014 at a conversion price of $11.11 per share of common stock. Since January 1, 2014, none of the 4 percent Convertible Notes were redeemed, however we have received redemption notices for $56 of the 4 percent Convertible Senior Notes which we expect to be redeemed in the first quarter of 2014.
	If the total $156 outstanding principal amount of the 4 percent Convertible Notes was converted, the total cost to settle the notes would be $1,094, assuming a conversion price of $77.95 (the closing price of our common stock on December 31, 2013) per share of common stock. The $156 principal amount would be settled in cash, and the remaining $938 could be settled in cash, shares of our common stock, or a combination thereof, at our discretion. Based on the December 31, 2013 closing stock price, approximately 12 million shares of stock, excluding any stock we would receive from the option counterparties as discussed below, would be issued if we settled the entire $938 of conversion value in excess of the principal amount in stock. The total cost to settle would change approximately $14 for each $1 (actual dollars) change in our stock price. If the full principal amount was converted at our December 31, 2013 closing stock price, we estimate that we would receive approximately $43 in either cash or stock from the option counterparties, after which the effective conversion price would be approximately $14.17.
	If Holdings undergoes a fundamental change (as defined in the indenture governing the 4 percent Convertible Notes), holders of the 4 percent Convertible Notes may require Holdings to repurchase all or any portion of their 4 percent Convertible Notes for cash at a price equal to 100 percent of the principal amount of the 4 percent Convertible Notes to be purchased plus any accrued and unpaid interest, including any additional interest, through but excluding the fundamental change purchase date. The difference between the December 31, 2013 carrying value of the 4 percent Convertible Notes and the $156 principal amount relates to the $20 unamortized portion of the original issue discount recognized in conjunction with the issuance of these notes, which is being amortized through the above maturity date. The original issue discount increased additional paid-in capital by $33, net of taxes, in our accompanying consolidated statements of stockholders’ equity (deficit), and represents the difference between the $173 of gross proceeds from the 4 percent Convertible Notes issuance and the fair value of the debt component of the 4 percent Convertible Notes at issuance. The effective interest rate on the debt component of the 4 percent Convertible Notes is 11.60 percent. Upon conversion of the 4 percent Convertible Notes, we pay cash for the principal amount of the note, and cash, shares of our common stock, or a combination thereof, at our discretion, for the portion of the conversion value that exceeds the principal amount of the note.
	In connection with the 4 percent Convertible Notes offering, Holdings entered into convertible note hedge transactions with option counterparties. The convertible note hedge transactions cost $26, and decreased additional paid-in capital by $17, net of taxes, in our accompanying consolidated statements of stockholders’ equity (deficit). The convertible note hedge transactions cover, subject to anti-dilution adjustments, 10.3 million shares of our common stock. The convertible note hedge transactions are intended to reduce, subject to a limit, the potential dilution with respect to our common stock upon conversion of the 4 percent Convertible Notes. The effect of the convertible note hedge transactions is to increase the effective conversion price to $15.56 per share, equal to an approximately 75 percent premium over the $8.89 closing price of our common stock at issuance. The effective conversion price is subject to change in certain circumstances, such as if the 4 percent Convertible Notes are converted prior to May 15, 2015. In the event the market value of our common stock exceeds the effective conversion price per share, the settlement amount received from such transactions will only partially offset the potential dilution. For example, if, at the time of exercise of the conversion right, the price of our common stock was $75.00 or $80.00 per share, assuming an effective conversion price of $15.56 per share, on a net basis, we would issue 11.3 million or 11.5 million shares, respectively.
	Assumed RSC Debt
	10 1/4 percent Senior Notes. In November 2009, RSC issued $200 aggregate principal amount of 10 1/4 percent Senior Notes (the “10 1/4 percent Notes”), which are due November 15, 2019. Upon consummation of the RSC merger, URNA assumed the 10 1/4 percent Notes. The 10 1/4 percent Notes are unsecured and are guaranteed by URNA's domestic subsidiaries, subject to limited exceptions. The 10 1/4 percent Notes may be redeemed on or after November 15, 2014 at specified redemption prices that range from 105.125 percent in 2014 to 100 percent in 2017 and thereafter. The indenture governing the 10 1/4 percent Notes contains certain restrictive covenants that apply to URNA and its restricted subsidiaries, including, among others, limitations on their ability to (i) incur additional debt, (ii) pay dividends or distributions on their capital stock or repurchase their capital stock, (iii) make certain investments, (iv) create liens on their assets to secure debt, (v) enter into transactions with affiliates, (vi) create limitations on the ability of the restricted subsidiaries to make dividends or distributions to their respective parents, (vii) merge or consolidate with another company and (viii) transfer and sell assets. The indenture also requires that, in the event of a change of control (as defined in the indenture), URNA must make an offer to purchase all of the then outstanding 10 1/4 percent Notes tendered at a purchase price in cash equal to 101 percent of the principal amount thereof plus accrued and unpaid interest, if any, thereon. The difference between the December 31, 2013 carrying value of the 10 1/4 percent Notes and the $200 principal amount relates to the $20 unamortized portion of the fair value adjustment recognized upon consummation of the RSC merger, which is being amortized through the above maturity date. The effective interest rate on the 10 1/4 percent Notes is 8.3 percent. In December 2013, we exercised our right to redeem the $200 principal amount of outstanding 10 1/4 percent Notes, and the notes were redeemed in January 2014. We paid a call premium of $26 in connection with the redemption, and we recognized a loss of approximately $6 in interest expense, net upon redemption. The loss represented the difference between the net carrying amount and the total purchase price of the notes.
	8 1/4 percent Senior Notes. In January 2011, RSC issued $650 aggregate principal amount of 8 1/4 percent Senior Notes (the “8 1/4 percent Notes”), which are due February 1, 2021. Upon consummation of the RSC merger, URNA assumed the 8 1/4 percent Notes. The 8 1/4 percent Notes are unsecured and are guaranteed by URNA's domestic subsidiaries, subject to limited exceptions. The 8 1/4 percent Notes may be redeemed on or after February 1, 2016 at specified redemption prices that range from 104.125 percent in 2016 to 100 percent in 2019 and thereafter. The indenture governing the 8 1/4 percent Notes contains certain restrictive covenants that apply to URNA and its restricted subsidiaries, including, among others, limitations on their ability to (i) incur additional debt, (ii) pay dividends or distributions on their capital stock or repurchase their capital stock, (iii) make certain investments, (iv) create liens on their assets to secure debt, (v) enter into transactions with affiliates, (vi) create limitations on the ability of the restricted subsidiaries to make dividends or distributions to their respective parents, (vii) merge or consolidate with another company and (viii) transfer and sell assets. The indenture also requires that, in the event of a change of control (as defined in the indenture), URNA must make an offer to purchase all of the then outstanding 8 1/4 percent Notes tendered at a purchase price in cash equal to 101 percent of the principal amount thereof plus accrued and unpaid interest, if any, thereon. The difference between the December 31, 2013 carrying value of the 8 1/4 percent Notes and the $650 principal amount relates to the $42 unamortized portion of the fair value adjustment recognized upon consummation of the RSC merger, which is being amortized through the above maturity date. The effective interest rate on the 8 1/4 percent Notes is 7.0 percent.
	Merger Financing Notes
	5 3/4 percent Senior Secured Notes. In March 2012, a special purpose entity formed for the purpose of issuing the notes and subsequently merged into URNA ("Funding SPV") issued $750 aggregate principal amount of 5 3/4 percent Senior Secured Notes (the “5 3/4 percent Notes”) which are due July 15, 2018. The net proceeds from the sale of the 5 3/4 percent Notes were approximately $733 (after deducting the initial purchasers' fees and offering expenses). Upon consummation of the RSC merger, URNA assumed the 5 3/4 percent Notes. The 5 3/4 percent Notes are secured and are guaranteed by Holdings and, subject to limited exceptions, URNA's domestic subsidiaries. The 5 3/4 percent Notes may be redeemed on or after July 15, 2015, at specified redemption prices that range from 102.875 percent in 2015, to 100 percent in 2017 and thereafter, plus accrued and unpaid interest. The indenture governing the 5 3/4 percent Notes contains certain restrictive covenants, including, among others, limitations on (i) liens; (ii) additional indebtedness; (iii) mergers, consolidations and acquisitions; (iv) sales, transfers and other dispositions of assets; (v) loans and other investments; (vi) dividends and other distributions, stock repurchases and redemptions and other restricted payments; (vii) dividends, other payments and other matters affecting subsidiaries; (viii) transactions with affiliates; and (ix) designations of unrestricted subsidiaries, as well as a requirement to timely file periodic reports with the SEC. The indenture also includes covenants relating to the grant of and maintenance of liens for the benefit of the notes collateral agent. Each of these covenants is subject to important exceptions and qualifications that would allow Holdings, URNA and their respective subsidiaries to engage in these activities under certain conditions. The indenture also requires that, in the event of a change of control (as defined in the indenture), URNA must make an offer to purchase all of the then-outstanding 5 3/4 percent Notes tendered at a purchase price in cash equal to 101 percent of the principal amount thereof, plus accrued and unpaid interest, if any, thereon.
	7 3/8 percent Senior Notes. In March 2012, Funding SPV issued $750 aggregate principal amount of 7 3/8 percent Senior Notes (the “7 3/8 percent Notes”) which are due May 15, 2020. The net proceeds from the sale of the 7 3/8 percent Notes were approximately $732 (after deducting the initial purchasers' fees and offering expenses). Upon consummation of the RSC merger, URNA assumed the 7 3/8 percent Notes. The 7 3/8 percent Notes are unsecured and are guaranteed by Holdings and, subject to limited exceptions, URNA's domestic subsidiaries. The 7 3/8 percent Notes may be redeemed on or after May 15, 2016, at specified redemption prices that range from 103.688 percent in 2016, to 100 percent in 2018 and thereafter, plus accrued and unpaid interest. The indenture governing the 7 3/8 percent Notes contains certain restrictive covenants, including, among others, limitations on (i) liens; (ii) additional indebtedness; (iii) mergers, consolidations and acquisitions; (iv) sales, transfers and other dispositions of assets; (v) loans and other investments; (vi) dividends and other distributions, stock repurchases and redemptions and other restricted payments; (vii) dividends, other payments and other matters affecting subsidiaries; (viii) transactions with affiliates; and (ix) designations of unrestricted subsidiaries, as well as a requirement to timely file periodic reports with the SEC. Each of these covenants is subject to important exceptions and qualifications that would allow Holdings, URNA and their respective subsidiaries to engage in these activities under certain conditions. The indenture also requires that, in the event of a change of control (as defined in the indenture), URNA must make an offer to purchase all of the then-outstanding 7 3/8 percent Notes tendered at a purchase price in cash equal to 101 percent of the principal amount thereof, plus accrued and unpaid interest, if any, thereon.
	7 5/8 percent Senior Notes. In March 2012, Funding SPV issued $1,325 aggregate principal amount of 7 5/8 percent Senior Notes (the “7 5/8 percent Notes”) which are due April 15, 2022. The net proceeds from the sale of the 7 5/8 percent Notes were approximately $1,295 (after deducting the initial purchasers' fees and offering expenses). Upon consummation of the RSC merger, URNA assumed the 7 5/8 percent Notes. The 7 5/8 percent Notes are unsecured and are guaranteed by Holdings and, subject to limited exceptions, URNA's domestic subsidiaries. The 7 5/8 percent Notes may be redeemed on or after April 15, 2017, at specified redemption prices that range from 103.813 percent in 2017, to 100 percent in 2020 and thereafter, plus accrued and unpaid interest. The indenture governing the 7 5/8 percent Notes contains certain restrictive covenants, including, among others, limitations on (i) liens; (ii) additional indebtedness; (iii) mergers, consolidations and acquisitions; (iv) sales, transfers and other dispositions of assets; (v) loans and other investments; (vi) dividends and other distributions, stock repurchases and redemptions and other restricted payments; (vii) dividends, other payments and other matters affecting subsidiaries; (viii) transactions with affiliates; and (ix) designations of unrestricted subsidiaries, as well as a requirement to timely file periodic reports with the SEC. Each of these covenants is subject to important exceptions and qualifications that would allow Holdings, URNA and their respective subsidiaries to engage in these activities under certain conditions. The indenture also requires that, in the event of a change of control (as defined in the indenture), URNA must make an offer to purchase all of the then-outstanding 7 5/8 percent Notes tendered at a purchase price in cash equal to 101 percent of the principal amount thereof, plus accrued and unpaid interest, if any, thereon.
	Loan Covenants and Compliance
	As of December 31, 2013, we were in compliance with the covenants and other provisions of the ABL facility, the accounts receivable securitization facility and the senior notes. Any failure to be in compliance with any material provision or covenant of these agreements could have a material adverse effect on our liquidity and operations.
	As discussed above, in October 2011, we amended the ABL facility. The only material financial covenants which currently exist relate to the fixed charge coverage ratio and the senior secured leverage ratio under the amended ABL facility. Since the October 2011 amendment of the facility and through December 31, 2013, availability under the ABL facility has exceeded the required threshold and, as a result, these maintenance covenants have been inapplicable. Subject to certain limited exceptions specified in the ABL facility, the fixed charge coverage ratio and the senior secured leverage ratio under the ABL facility will only apply in the future if availability under the ABL facility falls below the greater of 10 percent of the maximum revolver amount under the ABL facility and $150. Under our accounts receivable securitization facility, we are required, among other things, to maintain certain financial tests relating to: (i) the default ratio, (ii) the delinquency ratio, (iii) the dilution ratio and (iv) days sales outstanding.
	Maturities
	Maturities of the Company’s debt (exclusive of any unamortized original issue discount) for each of the next five years and thereafter at December 31, 2013 are as follows:
	2014	$	468
	2015	189
	2016	1,328
	2017	12
	2018	756
	Thereafter	4,384
	Total	$	7,137
	Our 4 percent Convertible Senior Notes mature in 2015, but are reflected as short-term debt in our consolidated balance sheet because they were redeemable at December 31, 2013. The 4 percent Convertible Senior Notes are reflected in the table above based on the contractual maturity date in 2015. In December 2013, we exercised our right to redeem the $200 principal amount of outstanding 10 1/4 percent Notes, and the notes were redeemed in January 2014. We used borrowings under our ABL facility to redeem the 10 1/4 percent Notes. The 10 1/4 percent Notes are reflected in the table above using the 2016 maturity date of the ABL facility.

	(2) 2012 non-deductible expenses and other includes a $6 Canadian tax benefit due to settlements with the Canadian Revenue Authority and a $2 transfer pricing tax benefit. 2011 non-deductible expenses and other includes $6 due to the non-deductibility of certain costs associated with the proposed RSC acquisition and $3 related to an adjustment of federal and state deferred tax liabilities.

	The Company's liability for unrecognized tax benefits relates to various foreign jurisdictions. The following table summarizes the activity related to the unrecognized tax benefits:

	Additions for tax positions of prior years related to RSC acquisition	—			6
	Settlements	—			(2		)
	Balance at December 31	$	23		$	17
	The gross unrecognized tax benefits as of December 31, 2013 and 2012 include $7 and $6, respectively, of tax benefits that would impact our effective tax rate if recognized.
	We include interest accrued on the underpayment of income taxes in interest expense, and penalties, if any, related to unrecognized tax benefits in selling, general and administrative expense. Interest expense of less than $1 related to income tax was reflected in our consolidated statements of income for each of the years ended December 31, 2013, 2012 and 2011.
	We file income tax returns in the United States and in several foreign jurisdictions. With few exceptions, we have completed our domestic and international income tax examinations, or the statute of limitations has expired in the respective jurisdictions, for years prior to 2007. The Internal Revenue Service (“IRS”) has completed audits for periods prior to 2010. Canadian authorities have concluded income tax audits for periods through 2010. Canadian transfer pricing for 2006 through 2010 is currently under audit. Included in the balance of unrecognized tax benefits at December 31, 2013 are certain tax positions under audit by the Canadian Revenue Authority ("CRA"), and it is reasonably possible that these audits will be concluded within the next 12 months. It is reasonably possible that the conclusion of these audits will result in a settlement of reported unrecognized tax benefits for those tax positions during the next 12 months. However, based on the status of the ongoing audit examinations and alternative settlement options available to the Company for certain of these tax positions, which could include legal proceedings, it is not possible to estimate the amount of the change, if any, to the previously recorded uncertain tax positions.
	For financial reporting purposes, income from continuing operations before income taxes for our foreign subsidiaries was $160, $143 and $86 for the years ended December 31, 2013, 2012 and 2011, respectively. At December 31, 2013, unremitted earnings of foreign subsidiaries were approximately $465. Since it is our intention to indefinitely reinvest these earnings, no U.S. taxes have been provided for these amounts. If we changed our reinvestment policy and decided to remit earnings as a dividend, a deferred tax liability would arise. Determination of the amount of unrecognized deferred tax liability on these unremitted taxes is not practicable.
	We have net operating loss carryforwards (“NOLs”) of $1,183 for state income tax purposes that expire from 2014 through 2033. We have recorded a valuation allowance against this deferred asset of less than $1 as of December 31, 2013 and 2012. We have NOLs of $551 for federal income tax purposes that expire beginning in 2031. We have not recorded a valuation allowance against this deferred tax asset because it is deemed more likely than not that such benefit will be realized in the future. There were no new NOLs for federal income tax recognized in 2013. In 2013, the Company utilized $430 of existing NOLs to offset tax liabilities.

Commitments and Contingencies Disclosure [Abstract]	'
Commitments and Contingencies	'
	Commitments and Contingencies
	We are subject to a number of claims and proceedings that generally arise in the ordinary conduct of our business. These matters include, but are not limited to, general liability claims (including personal injury, product liability, and property and auto claims), indemnification and guarantee obligations, employee injuries and employment-related claims, self-insurance obligations and contract and real estate matters. Based on advice of counsel and available information, including current status or stage of proceeding, and taking into account accruals for matters where we have established them, we currently believe that any liabilities ultimately resulting from these ordinary course claims and proceedings will not, individually or in the aggregate, have a material adverse effect on our consolidated financial position, results of operations or cash flows.
	Indemnification
	The Company indemnifies its officers and directors pursuant to indemnification agreements and may in addition indemnify these individuals as permitted by Delaware law.
	Operating Leases
	We lease rental equipment, real estate and certain office equipment under operating leases. Certain real estate leases require us to pay maintenance, insurance, taxes and certain other expenses in addition to the stated rental payments. Future minimum lease payments by year and in the aggregate, for non-cancelable operating leases with initial or remaining terms of one year or more are as follows at December 31, 2013:
		Real			Non-Rental
		Estate			Equipment
		Leases			Leases
	2014	$	98		$	28
	2015	87			29
	2016	72			22
	2017	54			21
	2018	35			19
	Thereafter	67			16
	Total	$	413		$	135
	Our real estate leases provide for varying terms, including customary escalation clauses. We evaluate our operating leases in accordance with GAAP. Our leases generally include default provisions that are customary, and do not contain material adverse change clauses, cross-default provisions or subjective default provisions. In these leases, the occurrence of an event of default is objectively determinable based on predefined criteria. Based on the facts and circumstances that existed at lease inception and with consideration of our history as a lessee, we believe that it is reasonable to assume that an event of default will not occur.
	Rent expense under all non-cancelable real estate, rental equipment and other equipment operating leases totaled $135, $175 and $122 for the years ended December 31, 2013, 2012 and 2011, respectively.
	Capital Leases
	Capital lease obligations consist primarily of vehicle and building leases with periods expiring at various dates through 2028. Capital lease obligations were $120 and $148 at December 31, 2013 and 2012, respectively. The following table presents capital lease financial statement information for the years ended December 31, 2013, 2012 and 2011, except for balance sheet information, which is presented as of December 31, 2013 and 2012:

	Capital lease obligations	$	120
	-1	The weighted average interest rate on our capital lease obligations as of December 31, 2013 was approximately 5.3 percent.
	Employee Benefit Plans
	We currently sponsor two defined contribution 401(k) retirement plans, which are subject to the provisions of the Employee Retirement Income Security Act of 1974. We also sponsor a deferred profit sharing plan for the benefit of the full-time employees of our Canadian subsidiaries. Under these plans, we match a percentage of the participants’ contributions up to a specified amount. Company contributions to the plans were $17, $11 and $6 in the years ended December 31, 2013, 2012 and 2011, respectively. The increase in Company contributions in 2013 from 2012 was primarily due to increased participation in the plans, including the impact of the RSC acquisition. The increase in Company contributions in 2012 from 2011 was primarily due to the impact of the RSC acquisition.
	Environmental Matters
	The Company and its operations are subject to various laws and related regulations governing environmental matters. Under such laws, an owner or lessee of real estate may be liable for the costs of removal or remediation of certain hazardous or toxic substances located on or in, or emanating from, such property, as well as investigation of property damage. We incur ongoing expenses associated with the removal of underground storage tanks and the performance of appropriate remediation at certain of our locations.

	Common Stock
	We have 500 million authorized shares of common stock, $0.01 par value. At December 31, 2013 and 2012, there were (i) 0.9 million and 1.3 million shares of common stock reserved for issuance pursuant to options granted under our stock option plans, respectively, (ii) 0.0 million and 1.3 million shares of common stock reserved for the conversion of outstanding QUIPS of the Trust, respectively, and (iii) 17.5 million and 18.9 million shares of common stock reserved for the conversion of 4 percent Convertible Notes, respectively. As discussed above (see note 12), based on the price of our common stock during the fourth quarter of 2013, holders of the 4 percent Convertible Notes may redeem them during the first quarter of 2014 at a conversion price of approximately $11.11 per share of common stock. Since January 1, 2014 (the beginning of the first quarter), none of the 4 percent Convertible Notes were redeemed, however we have received redemption notices for $56 of the 4 percent Convertible Senior Notes which we expect to be redeemed in the first quarter of 2014.
	As of December 31, 2013, there were an aggregate of 1.1 million outstanding time and performance-based restricted stock units ("RSUs") which vest in 2014, 2015 and 2016, and there were 1.8 million shares available for grant of stock and options under our 2010 Long Term Incentive Plan.

	Intrinsic value of options exercised	$	21		$	33			$	22
	Weighted-average grant date fair value per option	$	24.56		$	29.52			$	14.58
	In addition to stock options, the Company issues time-based and performance-based RSUs to certain officers and key executives under various plans. The RSUs automatically convert to shares of common stock on a one-for-one basis as the awards vest. The time-based RSUs typically vest over a three year vesting period beginning 12 months from the grant date and thereafter annually on the anniversary of the grant date. The performance-based RSUs vest over the performance period which is currently the calendar year. There were 603 thousand shares of common stock issued upon vesting of RSUs during 2013, net of 369 thousand shares surrendered to satisfy tax obligations. The Company measures the value of RSUs at fair value based on the closing price of the underlying common stock on the grant date. The Company amortizes the fair value of outstanding RSUs as stock-based compensation expense over the requisite service period on a straight-line basis, or sooner if the employee effectively vests upon termination of employment under certain circumstances. For performance-based RSUs, compensation expense is recognized to the extent that the satisfaction of the performance condition is considered probable.
	A summary of RSUs granted follows (RSUs in thousands):
		Year Ended December 31,

	RSUs granted	894			1,216				499
	Weighted-average grant date price per unit	$	57.5		$	43.98			$	30.98
	As of December 31, 2013, the total pretax compensation cost not yet recognized by the Company with regard to unvested RSUs was $22. The weighted-average period over which this compensation cost is expected to be recognized is 1.8 years.

	-1	The fourth quarter of 2013 includes a reduction in bad debt expense of $17 as compared to the fourth quarter of 2012 primarily due to improved receivable aging. In the fourth quarter of 2013, we recognized a benefit of $3 in cost of equipment rentals, excluding depreciation related to our provision for self-insurance reserves.
	-2	During the fourth quarter of 2012, we recognized $13 of charges associated with the RSC acquisition. Additionally, during the quarter, we recognized restructuring charges of $6, primarily reflecting branch closure charges associated with the RSC acquisition. During the quarter, we also recognized asset impairment charges of $2 which are primarily reflected in non-rental depreciation and amortization and principally relate to write-offs of leasehold improvements and other fixed assets. During the fourth quarter of 2012, we redeemed our 10 7/8 percent Senior Notes and all of our outstanding 1 7/8 percent Convertible Senior Subordinated Notes were converted. Upon redemption/conversion, we recognized a loss of $72 in interest expense, net. The loss represents the difference between the net carrying amount and the total purchase/conversion price of these securities. During the quarter, we also recognized a benefit of $6 in cost of equipment rentals, excluding depreciation related to our provision for self-insurance reserves. Additionally, operating income for the fourth quarter 2012 included $8 of costs, in the aggregate, primarily related to the merger, which should have been recognized in the second and third quarters of 2012. There was no impact on 2012 full year operating income.

Earnings Per Share [Abstract]	'
Earnings Per Share	'
	Earnings Per Share
	Basic earnings per share is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding. Diluted earnings per share is computed by dividing net income available to common stockholders by the weighted-average number of common shares plus the effect of dilutive potential common shares outstanding during the period. The diluted earnings per share for the years ended December 31, 2013, 2012 and 2011 exclude the impact of approximately 0.3 million, 1.8 million and 2.2 million common stock equivalents, respectively, since the effect of including these securities would be anti-dilutive. The following table sets forth the computation of basic and diluted earnings per share (shares in thousands):

	Condensed Consolidating Financial Information of Guarantor Subsidiaries
	URNA is 100 percent owned by Holdings (“Parent”) and has outstanding (i) certain indebtedness that is guaranteed by Parent, (ii) certain indebtedness that is guaranteed by both Parent and, with the exception of its U.S. special purpose vehicle which holds receivable assets relating to the Company’s accounts receivable securitization (the “SPV”), all of URNA’s U.S. subsidiaries (the “guarantor subsidiaries”) and (iii) certain indebtedness that is guaranteed by the guarantor subsidiaries. However, this indebtedness is not guaranteed by URNA’s foreign subsidiaries and the SPV (together, the “non-guarantor subsidiaries”). The guarantor subsidiaries are all 100 percent-owned and the guarantees are made on a joint and several basis. The guarantees are not full and unconditional because a guarantor subsidiary can be automatically released and relieved of its obligations under certain circumstances, including sale of the subsidiary guarantor, the sale of all or substantially all of the subsidiary guarantor's assets, the requirements for legal defeasance or covenant defeasance under the applicable indenture being met or designating the subsidiary guarantor as an unrestricted subsidiary for purposes of the applicable covenants. The guarantees are also subject to subordination provisions (to the same extent that the obligations of the issuer under the relevant notes are subordinated to other debt of the issuer) and to a standard limitation which provides that the maximum amount guaranteed by each guarantor will not exceed the maximum amount that can be guaranteed without making the guarantee void under fraudulent conveyance laws. Based on our understanding of Rule 3-10 of Regulation S-X ("Rule 3-10"), we believe that the guarantees of the guarantor subsidiaries comply with the conditions set forth in Rule 3-10 and therefore continue to utilize Rule 3-10 to present condensed consolidating financial information for Holdings, URNA, the guarantor subsidiaries and the non-guarantor subsidiaries. Separate consolidated financial statements of the guarantor subsidiaries have not been presented because management believes that such information would not be material to investors. However, condensed consolidating financial information is presented. Certain reclassifications of prior years’ amounts have been made to conform to the current year’s presentation.
	URNA covenants in the ABL facility, accounts receivable securitization facility and the other agreements governing our debt impose operating and financial restrictions on URNA, Parent and the guarantor subsidiaries, including limitations on the ability to pay dividends. As of December 31, 2013, the amount available for distribution under the most restrictive of these covenants was $466.
	The condensed consolidating financial information of Parent and its subsidiaries is as follows:

Summary of Significant Accounting Policies Disclosures [Abstract]	'
Cash Equivalents	'
	Cash Equivalents
	We consider all highly liquid instruments with maturities of three months or less when purchased to be cash equivalents. Our cash equivalents at December 31, 2013 consist of direct obligations of financial institutions rated A or better.
Allowance for Doubtful Accounts	'
	Allowance for Doubtful Accounts
	We maintain allowances for doubtful accounts. These allowances reflect our estimate of the amount of our receivables that we will be unable to collect based on historical write-off experience. Our estimate could require change based on changing circumstances, including changes in the economy or in the particular circumstances of individual customers. Accordingly, we may be required to increase or decrease our allowances. Trade receivables that have contractual maturities of one year or less are written-off when they are determined to be uncollectible based on the criteria necessary to qualify as a deduction for federal tax purposes. Write-offs of such receivables require management approval based on specified dollar thresholds.
Inventory	'
	Inventory
	Inventory consists of new equipment, contractor supplies, tools, parts, fuel and related supply items. Inventory is stated at the lower of cost or market. Cost is determined, depending on the type of inventory, using either a specific identification, weighted-average or first-in, first-out method.
Property and Equipment	'
	Rental Equipment
	Rental equipment, which includes service and delivery vehicles, is recorded at cost and depreciated over the estimated useful life of the equipment using the straight-line method. The range of estimated useful lives for rental equipment is two to 12 years. Rental equipment is depreciated to a salvage value of zero to 10 percent of cost. Rental equipment is depreciated whether or not it is out on rent. Costs we incur in connection with refurbishment programs that extend the life of our equipment are capitalized and amortized over the remaining useful life of the equipment. The costs incurred under these refurbishment programs were $44, $24 and $10 for the years ended December 31, 2013, 2012 and 2011, respectively, and are included in purchases of rental equipment in our consolidated statements of cash flows. Ordinary repair and maintenance costs are charged to operations as incurred. Repair and maintenance costs are included in cost of revenues on our consolidated statements of income. Repair and maintenance expense (including both labor and parts) for our rental equipment was $563, $455 and $291 for the years ended December 31, 2013, 2012 and 2011, respectively.
	Property and Equipment
	Property and equipment are recorded at cost and depreciated over their estimated useful lives using the straight-line method. The range of estimated useful lives for property and equipment is two to 39 years. Ordinary repair and maintenance costs are charged to expense as incurred. Leasehold improvements are amortized using the straight-line method over their estimated useful lives or the remaining life of the lease, whichever is shorter.
Purchase Price Allocation	'
	Purchase Price Allocation
	We have made a number of acquisitions in the past (including the acquisition of RSC Holdings Inc. (“RSC”) in 2012) and may continue to make acquisitions in the future. We allocate the cost of the acquired entity to the assets acquired and liabilities assumed based on their respective fair values at the date of acquisition. Long lived assets (principally rental equipment), goodwill and other intangible assets generally represent the largest components of our acquisitions. The intangible assets that we have acquired are non-compete agreements, customer relationships and trade names and associated trademarks. Goodwill is calculated as the excess of the cost of the acquired entity over the net of the fair value of the assets acquired and the liabilities assumed. Non-compete agreements, customer relationships and trade names and associated trademarks are valued based on an excess earnings or income approach based on projected cash flows.
	When we make an acquisition, we also acquire other assets and assume liabilities. These other assets and liabilities typically include, but are not limited to, parts inventory, accounts receivable, accounts payable and other working capital items. Because of their short-term nature, the fair values of these other assets and liabilities generally approximate the book values on the acquired entities' balance sheets.
Evaluation of Goodwill Impairment	'
	Evaluation of Goodwill Impairment
	Goodwill is tested for impairment annually or more frequently if an event or circumstance indicates that an impairment loss may have been incurred. Application of the goodwill impairment test requires judgment, including: the identification of reporting units; assignment of assets and liabilities to reporting units; assignment of goodwill to reporting units; determination of the fair value of each reporting unit; and an assumption as to the form of the transaction in which the reporting unit would be acquired by a market participant (either a taxable or nontaxable transaction).
	We estimate the fair value of our reporting units (which are our regions) using a combination of an income approach based on the present value of estimated future cash flows and a market approach based on market price data of shares of our Company and other corporations engaged in similar businesses as well as acquisition multiples paid in recent transactions within our industry (including our own acquisitions). We believe this approach, which utilizes multiple valuation techniques, yields the most appropriate evidence of fair value. We review goodwill for impairment utilizing a two-step process. The first step of the impairment test requires a comparison of the fair value of each of our reporting units' net assets to the respective carrying value of net assets. If the carrying value of a reporting unit's net assets is less than its fair value, no indication of impairment exists and a second step is not performed. If the carrying amount of a reporting unit's net assets is higher than its fair value, there is an indication that an impairment may exist and a second step must be performed. In the second step, the impairment is calculated by comparing the implied fair value of the reporting unit's goodwill (as if purchase accounting were performed on the testing date) with the carrying amount of the goodwill. If the carrying amount of the reporting unit's goodwill is greater than the implied fair value of its goodwill, an impairment loss must be recognized for the excess and charged to operations.
	Financial Accounting Standards Board ("FASB") guidance permits entities to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test.
	In connection with our goodwill impairment test that was conducted as of October 1, 2012, we bypassed the qualitative assessment for each of our reporting units and proceeded directly to the first step of the goodwill impairment test. Our goodwill impairment testing as of this date indicated that all of our reporting units had estimated fair values which exceeded their respective carrying amounts by at least 15 percent.
Restructuring Charges	'
	Restructuring Charges
	Costs associated with exit or disposal activities, including lease termination costs and certain employee severance costs associated with restructuring, branch closing or other activity, are recognized at fair value when they are incurred.
Other Intangible Assets	'
	Other Intangible Assets
	Other intangible assets consist of non-compete agreements, customer relationships and trade names and associated trademarks. The non-compete agreements are being amortized on a straight-line basis over initial periods of approximately 5 years. The customer relationships are being amortized either using the sum of the years' digits method or on a straight-line basis over initial periods ranging from 8 to 15 years. The trade names and associated trademarks are being amortized using the sum of the years' digits method over an initial period of 5 years. We believe that the amortization methods used reflect the estimated pattern in which the economic benefits will be consumed.
Long-Lived Assets	'
	Long-Lived Assets
	Long-lived assets are recorded at the lower of amortized cost or fair value. As part of an ongoing review of the valuation of long-lived assets, we assess the carrying value of such assets if facts and circumstances suggest they may be impaired. If this review indicates the carrying value of such an asset may not be recoverable, as determined by an undiscounted cash flow analysis over the remaining useful life, the carrying value would be reduced to its estimated fair value.
Translation of Foreign Currency	'
	Translation of Foreign Currency
	Assets and liabilities of our Canadian subsidiaries that have a functional currency other than U.S. dollars are translated into U.S. dollars using exchange rates at the balance sheet date. Revenues and expenses are translated at average exchange rates effective during the year. Foreign currency translation gains and losses are included as a component of accumulated other comprehensive income within stockholders’ equity.
Revenue Recognition	'
	Revenue Recognition
	Our rental contract periods are hourly, daily, weekly or monthly and we recognize equipment rental revenue on a straight-line basis. As part of this straight-line methodology, when the equipment is returned, we recognize as incremental revenue the excess, if any, between the amount the customer is contractually required to pay over the cumulative amount of revenue recognized to date. We record amounts billed to customers in excess of recognizable revenue as deferred revenue on our balance sheet. We had deferred revenue of $30 and $26 as of December 31, 2013 and 2012, respectively. Revenues from the sale of rental equipment and new equipment are recognized at the time of delivery to, or pick-up by, the customer and when collectibility is reasonably assured. Sales of contractor supplies are also recognized at the time of delivery to, or pick-up by, the customer. Service revenue is recognized as the services are performed. Sales tax amounts collected from customers are recorded on a net basis.
Delivery Expense	'
	Delivery Expense
	Equipment rentals include our revenues from fees we charge for equipment delivery. Delivery costs are charged to operations as incurred, and are included in cost of revenues on our consolidated statements of income.
Advertising Expense	'
	Advertising Expense
	We promote our business through local and national advertising in various media, including trade publications, yellow pages, the Internet, radio and direct mail. Advertising costs are generally expensed as incurred. Advertising expense, net of qualified advertising reimbursements, was $0 for each of the years ended December 31, 2013, 2012 and 2011.
Insurance	'
	Insurance
	We are insured for general liability, workers’ compensation and automobile liability, subject to deductibles or self-insured retentions per occurrence of $2 for general liability, $1 for workers’ compensation and $2 for automobile liability as of December 31, 2013 and 2012. Losses within these deductible amounts are accrued based upon the aggregate liability for reported claims incurred, as well as an estimated liability for claims incurred but not yet reported. These liabilities are not discounted. The Company is also self-insured for group medical claims but purchases “stop loss” insurance to protect itself from any one loss exceeding $600,000 (actual dollars).
Income Taxes	'
	Income Taxes
	We use the liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on the differences between financial statement and tax bases of assets and liabilities and are measured using the tax rates and laws that are expected to be in effect when the differences are expected to reverse. Recognition of deferred tax assets is limited to amounts considered by management to be more likely than not to be realized in future periods. The most significant positive evidence that we consider in the recognition of deferred tax assets is the expected reversal of cumulative deferred tax liabilities resulting from book versus tax depreciation of our rental equipment fleet that is well in excess of the deferred tax assets.
	We use a two-step approach for recognizing and measuring tax benefits taken or expected to be taken in a tax return regarding uncertainties in income tax positions. The first step is recognition: we determine whether it is more likely than not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. In evaluating whether a tax position has met the more-likely-than-not recognition threshold, we presume that the position will be examined by the appropriate taxing authority with full knowledge of all relevant information. The second step is measurement: a tax position that meets the more-likely-than-not recognition threshold is measured to determine the amount of benefit to recognize in the financial statements. The tax position is measured at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. Differences between tax positions taken in a tax return and amounts recognized in the financial statements will generally result in one or more of the following: an increase in a liability for income taxes payable, a reduction of an income tax refund receivable, a reduction in a deferred tax asset or an increase in a deferred tax liability.
Use of Estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Significant estimates impact the calculation of the allowance for doubtful accounts, depreciation and amortization, income taxes, reserves for claims, loss contingencies (including legal contingencies) and the fair values of financial instruments. Actual results could materially differ from those estimates.
Concentrations of Credit Risk	'
	Concentrations of Credit Risk
	Financial instruments that potentially subject us to significant concentrations of credit risk include cash and cash equivalents and accounts receivable. We maintain cash and cash equivalents with high quality financial institutions. Concentration of credit risk with respect to receivables is limited because a large number of geographically diverse customers make up our customer base. Our largest customer accounted for less than one percent of total revenues in each of 2013, 2012, and 2011. Our customer with the largest receivable balance represented approximately one percent and two percent of total receivables at December 31, 2013 and 2012, respectively. We manage credit risk through credit approvals, credit limits and other monitoring procedures.
Stock-Based Compensation	'
	Stock-Based Compensation
	We measure stock-based compensation at the grant date based on the fair value of the award and recognize stock-based compensation expense over the requisite service period. Determining the fair value of stock option awards requires judgment, including estimating stock price volatility, forfeiture rates and expected option life. Restricted stock awards are valued based on the fair value of the stock on the grant date and the related compensation expense is recognized over the service period. Similarly, for time-based restricted stock awards subject to graded vesting, we recognize compensation cost on a straight-line basis over the requisite service period. We classify cash flows from tax benefits resulting from tax deductions in excess of the compensation cost recognized for stock-based awards (“excess tax benefits”) as financing cash flows.

Business Combinations [Abstract]	'
Fair Value of Consideration Transferred	'
	The acquisition date fair value of the consideration transferred of $2.6 billion consisted of the following:
	Cash consideration	$	1,161
	Stock consideration (30 million shares valued based on the URI acquisition date stock price)	1,396
	Share-based compensation awards (1)	29
	Total purchase consideration	$	2,586
	(1) This relates to RSC stock options and restricted stock units which were outstanding as of the acquisition date. Each RSC stock option was converted into an adjusted United Rentals stock option to acquire a number of shares of United Rentals common stock, determined by multiplying the number of shares of RSC common stock subject to the RSC stock option by the option exchange ratio (rounded down, if necessary, to a whole share of United Rentals common stock). The “option exchange ratio” means the sum of (i) 0.2783 and (ii) the quotient determined by dividing $10.80 by the volume-weighted average of the closing sale prices of shares of URI common stock as reported on the NYSE composite transactions reporting system for each of the 10 consecutive trading days ending with the acquisition date. The option exchange ratio was 0.5161. The exercise price per share of United Rentals common stock subject to the adjusted United Rentals option is equal to the per share exercise price of such RSC stock option divided by the option exchange ratio (rounded up, if necessary, to the nearest whole cent). Each RSC restricted stock unit (other than an award held by a member of the RSC board who was not also an employee or officer of RSC at such time) was converted into an adjusted United Rentals restricted stock unit in an amount determined by multiplying the number of shares of RSC common stock subject to the RSC restricted stock unit by the option exchange ratio. The portion of the United Rentals replacement awards that has been included in the purchase consideration was calculated as $29 and is based on the vesting which occurred prior to the acquisition date.

	(1) The fair value of accounts receivables acquired was $238, and the gross contractual amount was $251. We estimated that $13 will be uncollectible.
	(2) The following table reflects the estimated fair values and useful lives of the acquired intangible assets identified based on our purchase accounting assessments:
		Fair value			Life (years)
	Customer relationships	$	1,094		15
	Trade names and associated trademarks	81			5
	Non-compete agreements	49			5
	Total	$	1,224
	(3) At the closing of the merger, URNA repaid RSC's senior ABL facility, 10 percent senior notes, and 9.5 percent senior notes. The repaid debt is reflected as short-term above as it was paid on the acquisition date. The RSC debt reflected in our consolidated balance sheet as of December 31, 2013 is discussed further in note 12 to the consolidated financial statements. The debt in the table above includes $1,555 of the repaid RSC debt, and the fair values of the following debt assumed by URNA:
	10 1/4 percent Senior Notes	$	(225	)
	8 1/4 percent Senior Notes	(699		)
	Capital leases	(99		)
	Total assumed debt	$	(1,023	)
	(4) All of the goodwill was assigned to our general rentals segment. The level of goodwill that resulted from the merger is primarily reflective of RSC's going-concern value, the value of RSC's assembled workforce, new customer relationships expected to arise from the merger, and operational synergies that we expect to achieve that would not be available to other market participants. $39 of the goodwill is expected to be deductible for income tax purposes.

	(1) Depreciation of rental equipment and non-rental depreciation were adjusted for the fair value mark-ups of equipment acquired in the RSC acquisition, the impact of which was offset by the impact of extending the useful lives of such equipment.
	(2) Cost of rental equipment sales was adjusted for the fair value mark-ups of rental equipment acquired in the RSC acquisition.
	(3) The intangible assets acquired in the RSC acquisition were amortized.
	(4) Interest expense was adjusted to reflect interest on the merger financing notes described in note 12 to the consolidated financial statements.
	(5) RSC historic interest on debt that is not part of the combined entity was eliminated.
	(6) RSC historic interest was adjusted for the fair value mark-ups of the debt acquired in the RSC acquisition.
	(7) The RSC merger related costs were eliminated as they were assumed to have been recognized prior to the pro forma acquisition date.
	(8) Restructuring charges comprised of severance costs and branch closure charges associated with the acquisition were recognized for 5 quarters (the period from the actual acquisition date through the end of the restructuring program) following the pro forma acquisition date. For the pro forma presentation, over 95 percent of the total charges are reflected in the first year following the pro forma acquisition date, which reflects the timing of the actual restructuring charges.

Fair Value Disclosures [Abstract]	'
Fair Value, by Balance Sheet Grouping	'
	The estimated fair values of our other financial instruments at December 31, 2013 and 2012 have been calculated based upon available market information or an appropriate valuation technique, and are as follows:
		December 31, 2013				December 31, 2012
		Carrying		Fair		Carrying		Fair
		Amount		Value		Amount		Value
	Level 1:
	Subordinated convertible debentures	$	—	$	—	$	55	$	63
	Senior and senior subordinated notes	5,381		5,848		5,387		5,881

	Level 3:
	Capital leases (2)	120		118		148		145
	-1	The fair value of the 4 percent Convertible Senior Notes is based on the market value of comparable notes. Consistent with the carrying amount, the fair value excludes the equity component of the notes. To exclude the equity component and calculate the fair value, we used an effective interest rate of 6.6 percent. As discussed below (see note 12), the total cost to settle the notes based on the closing price of our common stock on December 31, 2013 would be $1,094.
	-2	The fair value of capital leases reflects the present value of the leases using a 7.0 percent interest rate.

	-1	$1,142 and $53 were available under our ABL facility and accounts receivable securitization facility, respectively, at December 31, 2013. The ABL facility availability is reflected net of $52 of letters of credit. At December 31, 2013, the interest rates applicable to our ABL facility and accounts receivable securitization facility were 2.5 percent and 0.8 percent, respectively.
	-2	In connection with the RSC merger, on March 9, 2012, we issued the merger financing notes. See below for additional detail regarding each of the merger financing notes.
	-3	Upon consummation of the RSC merger, we assumed certain of RSC's debt, including capital leases. See below for additional detail regarding the assumed RSC debt.
	-4	In August 1998, a subsidiary trust of Holdings (the “Trust”) issued and sold $300 of 6 1/2 percent Convertible Quarterly Income Preferred Securities (“QUIPS”) in a private offering. The Trust used the proceeds from the offering to purchase 6 1/2 percent subordinated convertible debentures due 2028 (the “Debentures”), which resulted in Holdings receiving all of the net proceeds of the offering. The QUIPS were non-voting securities, carried a liquidation value of $50 (fifty dollars) per security and were convertible into Holdings’ common stock. During the year ended December 31, 2013, an aggregate of $55 of QUIPS was redeemed. In connection with these redemptions, during the year ended December 31, 2013, we retired $55 principal amount of our subordinated convertible debentures. As of December 31, 2013, there were no QUIPS or subordinated convertible debentures outstanding. Total long-term debt at December 31, 2012 excludes $55 of these Debentures, which were separately classified in our consolidated balance sheets and referred to as “subordinated convertible debentures.” The subordinated convertible debentures reflected the obligation to our subsidiary that issued the QUIPS. This subsidiary was not consolidated in our financial statements because we were not the primary beneficiary of the Trust. As of December 31, 2013, the Trust was liquidated.

	-1	The fourth quarter of 2013 includes a reduction in bad debt expense of $17 as compared to the fourth quarter of 2012 primarily due to improved receivable aging. In the fourth quarter of 2013, we recognized a benefit of $3 in cost of equipment rentals, excluding depreciation related to our provision for self-insurance reserves.
	-2	During the fourth quarter of 2012, we recognized $13 of charges associated with the RSC acquisition. Additionally, during the quarter, we recognized restructuring charges of $6, primarily reflecting branch closure charges associated with the RSC acquisition. During the quarter, we also recognized asset impairment charges of $2 which are primarily reflected in non-rental depreciation and amortization and principally relate to write-offs of leasehold improvements and other fixed assets. During the fourth quarter of 2012, we redeemed our 10 7/8 percent Senior Notes and all of our outstanding 1 7/8 percent Convertible Senior Subordinated Notes were converted. Upon redemption/conversion, we recognized a loss of $72 in interest expense, net. The loss represents the difference between the net carrying amount and the total purchase/conversion price of these securities. During the quarter, we also recognized a benefit of $6 in cost of equipment rentals, excluding depreciation related to our provision for self-insurance reserves. Additionally, operating income for the fourth quarter 2012 included $8 of costs, in the aggregate, primarily related to the merger, which should have been recognized in the second and third quarters of 2012. There was no impact on 2012 full year operating income.

Share consideration	$29	[1]
[1]	This relates to RSC stock options and restricted stock units which were outstanding as of the acquisition date. Each RSC stock option was converted into an adjusted United Rentals stock option to acquire a number of shares of United Rentals common stock, determined by multiplying the number of shares of RSC common stock subject to the RSC stock option by the option exchange ratio (rounded down, if necessary, to a whole share of United Rentals common stock). The “option exchange ratio” means the sum of (i) 0.2783 and (ii) the quotient determined by dividing $10.80 by the volume-weighted average of the closing sale prices of shares of URI common stock as reported on the NYSE composite transactions reporting system for each of the 10 consecutive trading days ending with the acquisition date. The option exchange ratio was 0.5161. The exercise price per share of United Rentals common stock subject to the adjusted United Rentals option is equal to the per share exercise price of such RSC stock option divided by the option exchange ratio (rounded up, if necessary, to the nearest whole cent). Each RSC restricted stock unit (other than an award held by a member of the RSC board who was not also an employee or officer of RSC at such time) was converted into an adjusted United Rentals restricted stock unit in an amount determined by multiplying the number of shares of RSC common stock subject to the RSC restricted stock unit by the option exchange ratio. The portion of the United Rentals replacement awards that has been included in the purchase consideration was calculated as $29 and is based on the vesting which occurred prior to the acquisition date.

[1]	The fair value of accounts receivables acquired was $238, and the gross contractual amount was $251. We estimated that $13 will be uncollectible.

[3]	At the closing of the merger, URNA repaid RSC's senior ABL facility, 10 percent senior notes, and 9.5 percent senior notes. The repaid debt is reflected as short-term above as it was paid on the acquisition date. The RSC debt reflected in our consolidated balance sheet as of December 31, 2013 is discussed further in note 12 to the consolidated financial statements. The debt in the table above includes $1,555 of the repaid RSC debt, and the fair values of the following debt assumed by URNA: 10 1/4 percent Senior Notes$(225) 8 1/4 percent Senior Notes(699) Capital leases(99) Total assumed debt$(1,023)
[4]	The total carrying amount of goodwill for all periods in the table above is reflected net of $1,557 of accumulated impairment charges, which were primarily recorded in our general rentals segment.
[5]	All of the goodwill was assigned to our general rentals segment. The level of goodwill that resulted from the merger is primarily reflective of RSC's going-concern value, the value of RSC's assembled workforce, new customer relationships expected to arise from the merger, and operational synergies that we expect to achieve that would not be available to other market participants. $39 of the goodwill is expected to be deductible for income tax purposes.

The fourth quarter of 2013 includes a reduction in bad debt expense of $17 as compared to the fourth quarter of 2012 primarily due to improved receivable aging. In the fourth quarter of 2013, we recognized a benefit of $3 in cost of equipment rentals, excluding depreciation related to our provision for self-insurance reserves.

[2]

During the fourth quarter of 2012, we recognized $13 of charges associated with the RSC acquisition. Additionally, during the quarter, we recognized restructuring charges of $6, primarily reflecting branch closure charges associated with the RSC acquisition. During the quarter, we also recognized asset impairment charges of $2 which are primarily reflected in non-rental depreciation and amortization and principally relate to write-offs of leasehold improvements and other fixed assets. During the fourth quarter of 2012, we redeemed our 10 7/8 percent Senior Notes and all of our outstanding 1 7/8 percent Convertible Senior Subordinated Notes were converted. Upon redemption/conversion, we recognized a loss of $72 in interest expense, net. The loss represents the difference between the net carrying amount and the total purchase/conversion price of these securities. During the quarter, we also recognized a benefit of $6 in cost of equipment rentals, excluding depreciation related to our provision for self-insurance reserves. Additionally, operating income for the fourth quarter 2012 included $8 of costs, in the aggregate, primarily related to the merger, which should have been recognized in the second and third quarters of 2012. There was no impact on 2012 full year operating income.

[3]

Depreciation of rental equipment and non-rental depreciation were adjusted for the fair value mark-ups of equipment acquired in the RSC acquisition, the impact of which was offset by the impact of extending the useful lives of such equipment.

[4]

Cost of rental equipment sales was adjusted for the fair value mark-ups of rental equipment acquired in the RSC acquisition.

[5]

The intangible assets acquired in the RSC acquisition were amortized.

[6]

Interest expense was adjusted to reflect interest on the merger financing notes described in note 12 to the consolidated financial statements.

[7]

RSC historic interest on debt that is not part of the combined entity was eliminated.

[8]

RSC historic interest was adjusted for the fair value mark-ups of the debt acquired in the RSC acquisition.

[9]

The RSC merger related costs were eliminated as they were assumed to have been recognized prior to the pro forma acquisition date.

[10]

Restructuring charges comprised of severance costs and branch closure charges associated with the acquisition were recognized for 5 quarters (the period from the actual acquisition date through the end of the restructuring program) following the pro forma acquisition date. For the pro forma presentation, over 95 percent of the total charges are reflected in the first year following the pro forma acquisition date, which reflects the timing of the actual restructuring charges.

[1]	The fair value of the 4 percent Convertible Senior Notes is based on the market value of comparable notes. Consistent with the carrying amount, the fair value excludes the equity component of the notes. To exclude the equity component and calculate the fair value, we used an effective interest rate of 6.6 percent. As discussed below (see note 12), the total cost to settle the notes based on the closing price of our common stock on December 31, 2013 would be $1,094.
[2]	The fair value of capital leases reflects the present value of the leases using a 7.0 percent interest rate.

$1,142 and $53 were available under our ABL facility and accounts receivable securitization facility, respectively, at December 31, 2013. The ABL facility availability is reflected net of $52 of letters of credit. At December 31, 2013, the interest rates applicable to our ABL facility and accounts receivable securitization facility were 2.5 percent and 0.8 percent, respectively.

[2]

In August 1998, a subsidiary trust of Holdings (the “Trust”) issued and sold $300 of 6 1/2 percent Convertible Quarterly Income Preferred Securities (“QUIPS”) in a private offering. The Trust used the proceeds from the offering to purchase 6 1/2 percent subordinated convertible debentures due 2028 (the “Debentures”), which resulted in Holdings receiving all of the net proceeds of the offering. The QUIPS were non-voting securities, carried a liquidation value of $50 (fifty dollars) per security and were convertible into Holdings’ common stock. During the year ended December 31, 2013, an aggregate of $55 of QUIPS was redeemed. In connection with these redemptions, during the year ended December 31, 2013, we retired $55 principal amount of our subordinated convertible debentures. As of December 31, 2013, there were no QUIPS or subordinated convertible debentures outstanding. Total long-term debt at December 31, 2012 excludes $55 of these Debentures, which were separately classified in our consolidated balance sheets and referred to as “subordinated convertible debentures.” The subordinated convertible debentures reflected the obligation to our subsidiary that issued the QUIPS. This subsidiary was not consolidated in our financial statements because we were not the primary beneficiary of the Trust. As of December 31, 2013, the Trust was liquidated.

Upon consummation of the RSC merger, we assumed certain of RSC's debt, including capital leases. See below for additional detail regarding the assumed RSC debt.

[4]

The fair value of the 4 percent Convertible Senior Notes is based on the market value of comparable notes. Consistent with the carrying amount, the fair value excludes the equity component of the notes. To exclude the equity component and calculate the fair value, we used an effective interest rate of 6.6 percent. As discussed below (see note 12), the total cost to settle the notes based on the closing price of our common stock on December 31, 2013 would be $1,094.

The fourth quarter of 2013 includes a reduction in bad debt expense of $17 as compared to the fourth quarter of 2012 primarily due to improved receivable aging. In the fourth quarter of 2013, we recognized a benefit of $3 in cost of equipment rentals, excluding depreciation related to our provision for self-insurance reserves.

[2]

During the fourth quarter of 2012, we recognized $13 of charges associated with the RSC acquisition. Additionally, during the quarter, we recognized restructuring charges of $6, primarily reflecting branch closure charges associated with the RSC acquisition. During the quarter, we also recognized asset impairment charges of $2 which are primarily reflected in non-rental depreciation and amortization and principally relate to write-offs of leasehold improvements and other fixed assets. During the fourth quarter of 2012, we redeemed our 10 7/8 percent Senior Notes and all of our outstanding 1 7/8 percent Convertible Senior Subordinated Notes were converted. Upon redemption/conversion, we recognized a loss of $72 in interest expense, net. The loss represents the difference between the net carrying amount and the total purchase/conversion price of these securities. During the quarter, we also recognized a benefit of $6 in cost of equipment rentals, excluding depreciation related to our provision for self-insurance reserves. Additionally, operating income for the fourth quarter 2012 included $8 of costs, in the aggregate, primarily related to the merger, which should have been recognized in the second and third quarters of 2012.

[4]

This reflects transaction costs associated with the RSC acquisition discussed in note 3 to our consolidated financial statements.

[5]

This reflects the amortization of the intangible assets acquired in the RSC acquisition.

[6]

This reflects the impact of extending the useful lives of equipment acquired in the RSC acquisition, net of the impact of additional depreciation associated with the fair value mark-up of such equipment.

[7]

This reflects additional costs recorded in cost of rental equipment sales, cost of equipment rentals, excluding depreciation, and cost of contractor supplies sales associated with the fair value mark-up of rental equipment and inventory acquired in the RSC acquisition. The costs relate to equipment and inventory acquired in the RSC acquisition and subsequently sold.

[8]

As discussed in note 12 to our consolidated financial statements, in March 2012, we issued $2,825 of debt in connection with the RSC merger. The pre-close RSC merger related interest expense reflects the interest expense recorded on this debt prior to the acquisition date.

[9]

This reflects a reduction of interest expense associated with the fair value mark-up of debt acquired in the RSC acquisition. See note 12 to our consolidated financial statements for additional detail on the acquired debt.

[10]

As discussed in note 5 to our consolidated financial statements, this reflects severance costs and branch closure charges associated with the RSC merger and our closed restructuring program.

[11]

As discussed in note 5 to our consolidated financial statements, this charge primarily reflects write-offs of leasehold improvements and other fixed assets in connection with the RSC acquisition and our closed restructuring program.

[12]

This reflects a gain recognized upon the sale of a former subsidiary that developed and marketed software.

In August 1998, a subsidiary trust of Holdings (the “Trust”) issued and sold $300 of 6 1/2 percent Convertible Quarterly Income Preferred Securities (“QUIPS”) in a private offering. The Trust used the proceeds from the offering to purchase 6 1/2 percent subordinated convertible debentures due 2028 (the “Debentures”), which resulted in Holdings receiving all of the net proceeds of the offering. The QUIPS were non-voting securities, carried a liquidation value of $50 (fifty dollars) per security and were convertible into Holdings’ common stock. During the year ended December 31, 2013, an aggregate of $55 of QUIPS was redeemed. In connection with these redemptions, during the year ended December 31, 2013, we retired $55 principal amount of our subordinated convertible debentures. As of December 31, 2013, there were no QUIPS or subordinated convertible debentures outstanding. Total long-term debt at December 31, 2012 excludes $55 of these Debentures, which were separately classified in our consolidated balance sheets and referred to as “subordinated convertible debentures.” The subordinated convertible debentures reflected the obligation to our subsidiary that issued the QUIPS. This subsidiary was not consolidated in our financial statements because we were not the primary beneficiary of the Trust. As of December 31, 2013, the Trust was liquidated.

The fourth quarter of 2013 includes a reduction in bad debt expense of $17 as compared to the fourth quarter of 2012 primarily due to improved receivable aging. In the fourth quarter of 2013, we recognized a benefit of $3 in cost of equipment rentals, excluding depreciation related to our provision for self-insurance reserves.

[2]

During the fourth quarter of 2012, we recognized $13 of charges associated with the RSC acquisition. Additionally, during the quarter, we recognized restructuring charges of $6, primarily reflecting branch closure charges associated with the RSC acquisition. During the quarter, we also recognized asset impairment charges of $2 which are primarily reflected in non-rental depreciation and amortization and principally relate to write-offs of leasehold improvements and other fixed assets. During the fourth quarter of 2012, we redeemed our 10 7/8 percent Senior Notes and all of our outstanding 1 7/8 percent Convertible Senior Subordinated Notes were converted. Upon redemption/conversion, we recognized a loss of $72 in interest expense, net. The loss represents the difference between the net carrying amount and the total purchase/conversion price of these securities. During the quarter, we also recognized a benefit of $6 in cost of equipment rentals, excluding depreciation related to our provision for self-insurance reserves. Additionally, operating income for the fourth quarter 2012 included $8 of costs, in the aggregate, primarily related to the merger, which should have been recognized in the second and third quarters of 2012. There was no impact on 2012 full year operating income.

[1]

The fourth quarter of 2013 includes a reduction in bad debt expense of $17 as compared to the fourth quarter of 2012 primarily due to improved receivable aging. In the fourth quarter of 2013, we recognized a benefit of $3 in cost of equipment rentals, excluding depreciation related to our provision for self-insurance reserves.

[2]

During the fourth quarter of 2012, we recognized $13 of charges associated with the RSC acquisition. Additionally, during the quarter, we recognized restructuring charges of $6, primarily reflecting branch closure charges associated with the RSC acquisition. During the quarter, we also recognized asset impairment charges of $2 which are primarily reflected in non-rental depreciation and amortization and principally relate to write-offs of leasehold improvements and other fixed assets. During the fourth quarter of 2012, we redeemed our 10 7/8 percent Senior Notes and all of our outstanding 1 7/8 percent Convertible Senior Subordinated Notes were converted. Upon redemption/conversion, we recognized a loss of $72 in interest expense, net. The loss represents the difference between the net carrying amount and the total purchase/conversion price of these securities. During the quarter, we also recognized a benefit of $6 in cost of equipment rentals, excluding depreciation related to our provision for self-insurance reserves. Additionally, operating income for the fourth quarter 2012 included $8 of costs, in the aggregate, primarily related to the merger, which should have been recognized in the second and third quarters of 2012. There was no impact on 2012 full year operating income.

[3]

There were no material reclassifications from accumulated other comprehensive income reflected in other comprehensive income (loss) during the years ended December 31, 2013, 2012 or 2011. There is no tax impact related to the foreign currency translation adjustments, as the earnings are considered permanently reinvested. There were no material taxes associated with other comprehensive income (loss) during the years ended December 31, 2013, 2012 or 2011.

[4]

Includes interest expense prior to the April 30, 2012 RSC acquisition date on the merger financing debt issued by Funding SPV, as discussed further in note 12 to our consolidated financial statements.
