Basis Of Presentation And Recently Issued Accounting Pronouncements [Abstract]	'
Basis of Presentation and Recently Issued Accounting Pronouncements	'
	Basis of Presentation and Recently Issued Accounting Pronouncements
	Basis of Presentation
	Avis Budget Group, Inc. provides car and truck rentals and ancillary services to businesses and consumers worldwide. The accompanying unaudited Consolidated Condensed Financial Statements include the accounts and transactions of Avis Budget Group, Inc. and its subsidiaries (“Avis Budget”), as well as entities in which Avis Budget directly or indirectly has a controlling financial interest (collectively, the “Company”), and have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission for interim financial reporting.
	The Company operates the following business segments:
	•	North America—provides car rentals in the United States and vehicle rentals in Canada, as well as ancillary products and services, and operates the Company’s Zipcar car sharing business.
	•	International—provides, and licenses the Company’s brands to third parties for, vehicle rentals and ancillary products and services primarily in Europe, the Middle East, Asia, Africa, South America, Central America, the Caribbean, Australia and New Zealand.
	•	Truck Rental—provides truck rentals and ancillary products and services to consumers and commercial users in the United States.
	In presenting the Consolidated Condensed Financial Statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”), management makes estimates and assumptions that affect the amounts reported and related disclosures. Estimates, by their nature, are based on judgment and available information. Accordingly, actual results could differ from those estimates. In management’s opinion, the Consolidated Condensed Financial Statements contain all adjustments necessary for a fair presentation of interim results reported. The results of operations reported for interim periods are not necessarily indicative of the results of operations for the entire year or any subsequent interim period. These financial statements should be read in conjunction with the Company’s 2012 Annual Report on Form 10-K and Form 10-K/A.
	Vehicle Programs.  The Company presents separately the financial data of its vehicle programs. These programs are distinct from the Company’s other activities since the assets under vehicle programs are generally funded through the issuance of debt that is collateralized by such assets. The income generated by these assets is used, in part, to repay the principal and interest associated with the debt. Cash inflows and outflows relating to the acquisition of such assets and the principal debt repayment or financing of such assets are classified as activities of the Company’s vehicle programs. The Company believes it is appropriate to segregate the financial data of its vehicle programs because, ultimately, the source of repayment of such debt is the realization of such assets.
	Transaction-related Costs. The Company completed the acquisition of Zipcar on March 14, 2013 and the acquisition of Payless Car Rental ("Payless") on July 15, 2013. During the three and nine months ended September 30, 2013, transaction-related costs primarily include expenses related to the integration of Avis Europe’s operations with those of the Company and costs related to the acquisition and integration of Zipcar and Payless. In the three and nine months ended September 30, 2012, transaction-related costs primarily included expenses related to the integration of Avis Europe’s operations with the Company’s.
	Currency Transactions. The Company records the gain or loss of foreign-currency transactions on certain intercompany loans and gain or loss on intercompany loan hedges within interest expense related to corporate debt, net. During the three and nine months ended September 30, 2013, the Company recorded losses of $1 million and $8 million, respectively, on such items. In the three and nine months ended September 30, 2012, the Company recorded losses of $3 million and $12 million, respectively, on such items.
	Adoption of New Accounting Standards
	On January 1, 2013, as a result of the issuance of a new accounting pronouncement, the Company adopted, as required, Accounting Standards Update No. 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income,” which requires companies to disclose additional information about amounts reclassified out of accumulated other comprehensive income by component. The adoption of this pronouncement resulted in incremental disclosure about activity and amounts reclassified out of accumulated other comprehensive income.

Restructuring	'
	Restructuring Activities
	During fourth quarter 2012, the Company initiated a strategic restructuring initiative to better position the business of its Truck Rental segment, in which it will close certain rental locations and decrease the size of the rental fleet, which the Company believes will increase fleet utilization and reduce costs. During the nine months ended September 30, 2013, as part of this process, the Company recorded restructuring expense of $19 million. The Company expects further restructuring expenses of approximately $3 million to be incurred, through the completion of this initiative, in 2013.
	In 2011, the Company implemented a restructuring initiative to identify synergies across the Company, enhance organizational efficiencies and consolidate and rationalize processes and facilities. During the nine months ended September 30, 2013, as part of this process, the Company formally communicated the termination of employment to approximately 370 employees and recorded $20 million of expense in connection with these initiatives. These expenses primarily represent severance, outplacement services and other costs associated with employee terminations. As of September 30, 2013, the Company has terminated approximately 300 of these employees. The Company expects further restructuring expenses of approximately $18 million to be incurred in 2013.
	The following tables summarize the changes to our restructuring-related liabilities and identify the amounts recorded within the Company’s reportable segments, and by category, for restructuring expenses and corresponding payments and utilizations:

	Earnings Per Share
	The following table sets forth the computation of basic and diluted earnings per share (“EPS”) (shares in millions):
			Three Months Ended				Nine Months Ended

			2013		2012		2013		2012

	__________
	(a)	For the three and nine months ended September 30, 2013, the number of anti-dilutive securities which were excluded from the computation of diluted earnings per share was not significant. For the three and nine months ended September 30, 2012, 0.2 million outstanding options and 8.9 million warrants have an anti-dilutive effect and therefore are excluded from the computation of diluted weighted average shares outstanding.

Acquisitions	'
	Acquisitions
	Zipcar
	On March 14, 2013, the Company completed the acquisition of the entire issued share capital of Zipcar, the leading car sharing company, for $473 million, net of acquired cash. The acquisition increased the Company’s growth potential and its ability to better serve a greater variety of customer transportation needs.
	The excess of the purchase price over preliminary fair value of net assets acquired was allocated to goodwill, which was assigned to the Company’s North America segment. The goodwill is not expected to be deductible for tax purposes. The fair value of the assets acquired and liabilities assumed has not yet been finalized and is therefore subject to change. In connection with this acquisition, $188 million was recorded in identifiable intangible assets (consisting of $112 million related to trademarks and $76 million related to customer relationships) and $275 million was recorded in goodwill. The trademark assets are indefinite-lived and the customer relationship intangibles will be amortized over an estimated life of 8 years.
	Brazilian licensee
	On August 12, 2013, the Company acquired a 50% ownership stake in its Brazilian licensee for $53 million. Approximately $11 million of the total consideration was paid in the third quarter of 2013 and the remainder is expected to be paid by the end of first quarter 2014. The Company’s investment significantly increases its presence in the Brazilian car rental market.
	The Company’s investment in its Brazilian licensee was recorded as an equity investment within Other non-current assets, and the Company’s share of the Brazilian licensee’s operating results is reported within Operating expenses. In conjunction with the acquisition, the Company agreed to the payment of contingent consideration of up to $13 million based on the Brazilian licensee’s future financial performance. The fair value of the contingent consideration was estimated by utilizing a Monte Carlo simulation technique, based on a range of possible future results, and no value was attributed to the contingent consideration at the acquisition date. At September 30, 2013, the Company’s investment totaled approximately $20 million, which is net of an impairment charge of $33 million ($33 million, net of tax). The impairment charge was recorded at the time of the investment based on a combination of observable and unobservable fair value inputs (Level 3), specifically a combination of the Income approach‐discounted cash flow method and the Market approach-public company market multiple method.
	Payless Car Rental
	On July 15, 2013, the Company completed the acquisition of Payless for $50 million in cash. The acquisition provides the Company with a meaningful position in the deep-value segment of the car rental industry.
	The excess of the purchase price over preliminary fair value of net assets acquired was allocated to goodwill, which was assigned to the Company’s North America segment. The goodwill is not expected to be deductible for tax purposes. The fair value of the assets acquired and liabilities assumed has not yet been finalized and is therefore subject to change. In connection with this acquisition, $23 million was recorded in identifiable intangible assets (consisting of $16 million related to trademarks and $7 million related to license agreements) and $27 million was recorded in goodwill. The trademark assets are indefinite-lived and the license agreements will be amortized over an estimated life of 15 years.
	Apex Car Rentals
	In October 2012, the Company completed the acquisition of the assets of Apex Car Rentals (“Apex”), a leading deep-value car rental company in New Zealand and Australia, operating a fleet of approximately 4,000 rental vehicles. In conjunction with the acquisition, the Company paid $63 million in cash (including the acquisition of fleet) and agreed to the payment of contingent consideration with an estimated acquisition date fair value of $9 million. The contingent consideration consists of a maximum of $26 million in additional payments that are contingent on Apex’ future financial performance, and the fair value of the contingent consideration at the acquisition date was estimated by utilizing a Monte Carlo simulation technique, based on a range of possible future results. The allocation of the purchase price of Apex principally includes vehicles of $33 million, trademarks of $21 million and goodwill of $16 million, which were allocated to the Company’s International segment. The goodwill is not expected to be deductible for tax purposes.

Financial Instruments	'
	Financial Instruments
	The fair value of the Company’s financial instruments is generally determined by reference to market values resulting from trading on a national securities exchange or in an over-the-counter market. In some cases where quoted market prices are not available, prices are derived by considering the yield of the benchmark security that was issued to initially price the instruments and adjusting this rate by the credit spread that market participants would demand for the instruments as of the measurement date. The carrying amounts of cash and cash equivalents; receivables, net; program cash and accounts payable and other current liabilities approximate fair value due to the short-term maturities of these assets and liabilities.
	Debt Instruments
	The carrying amounts and estimated fair values of debt instruments were as follows:
			As of September 30, 2013						As of December 31, 2012
			Carrying			Estimated			Carrying		Estimated
			Amount			Fair			Amount		Fair

	Net Investment Hedge
	The Company has designated its 6% Euro-denominated notes issued March 2013 as a hedge of its net investment in Euro-denominated foreign operations. The Company records the effective portion of the gain or loss on this net investment hedge, net of taxes, in accumulated other comprehensive income as part of currency translation adjustments. For the three months and nine months ended September 30, 2013, the Company has recorded an $8 million loss, net of tax, in accumulated other comprehensive income. Any ineffective portion of the net investment hedge is immediately reclassified from accumulated other comprehensive income into earnings. There was no ineffectiveness during the three and nine months ended September 30, 2013 and the Company does not expect to reclassify any amounts from accumulated other comprehensive income into earnings over the next 12 months.
	Derivative Instruments and Hedging Activities
	The Company uses foreign exchange contracts to manage its exposure to changes in currency exchange rates associated with its foreign currency denominated receivables and forecasted royalties, forecasted earnings of foreign subsidiaries and forecasted foreign currency denominated acquisitions. The Company primarily hedges its foreign currency exposure to the Australian, Canadian and New Zealand dollars, the Euro and the British pound sterling. These forward contracts do not qualify for hedge accounting treatment; however, the fluctuations in the value of these forward contracts largely offset the impact of changes in the value of the underlying risk they economically hedge.
	The Company uses various hedging strategies including interest rate swaps and interest rate caps to create an appropriate mix of fixed and floating rate assets and liabilities. The Company uses interest rate swaps to manage the risk related to its floating rate corporate debt and its floating rate vehicle-backed debt. The Company records the effective portion of changes in the fair value of its cash flow hedges to other comprehensive income, net of tax, and subsequently reclassifies these amounts into earnings in the period during which the hedged transaction is recognized. The Company records the gains or losses related to freestanding derivatives, which are not designated as a hedge for accounting purposes, in its consolidated results of operations. The changes in fair values of hedges that are determined to be ineffective are immediately reclassified from accumulated other comprehensive income into earnings. The Company estimates that the amount of gains or losses currently recorded in accumulated other comprehensive income which will be recognized in earnings over the next 12 months is not material.
	From time to time, the Company enters into derivative commodity contracts to manage its exposure to changes in the price of unleaded gasoline. Changes in the fair value of these derivatives are recorded within operating expenses.
	Certain of the Company’s derivative instruments contain collateral support provisions that require the Company to post cash collateral to the extent that such derivatives are in a liability position. The aggregate fair value of such derivatives and the aggregate fair value of assets needed to settle these derivatives as of September 30, 2013 was approximately $3 million, for which the Company has posted cash collateral in the normal course of business.
	As of September 30, 2013, the Company held derivative instruments with absolute notional values as follows:
		As of
		30-Sep-13
	Interest rate caps (a)	$	6,959
	Interest rate swaps	904
	Foreign exchange forward contracts	77
	Foreign exchange swaps	704

	(a)	Represents $4.7 billion of interest rate caps sold and approximately $2.2 billion of interest rate caps purchased. These amounts exclude $2.5 billion of interest rate caps purchased by the Company’s Avis Budget Rental Car Funding (AESOP) LLC (“Avis Budget Rental Car Funding”) subsidiary.
	As of September 30, 2013, the Company also had commodity contracts for the purchase of 11 million gallons of unleaded gasoline.
	The Company used significant observable inputs (Level 2 inputs) to determine the fair value of its derivative assets and liabilities. Derivatives entered into by the Company are typically executed over-the-counter and are valued using various valuation techniques, as no quoted market prices exist for such instruments. The valuation technique and inputs depend on the type of derivative and the nature of the underlying exposure. The principal techniques used to value these instruments are discounted cash flows and Black-Scholes option valuation models. These models take into account a variety of factors including, where applicable, maturity, commodity prices, interest rate yield curves of the Company and counterparties, credit curves, counterparty creditworthiness and currency exchange rates. These factors are applied on a consistent basis and are based upon observable inputs.
	Fair values of derivative instruments were as follows:
			As of September 30, 2013						As of December 31, 2012
			Fair Value,			Fair Value,			Fair Value,		Fair Value,

	The Company’s effective tax rate for the nine months ended September 30, 2013 is a provision of 67.4%. Such rate differs from the Federal statutory rate of 35.0% primarily due to the treatment of a portion of the expenses for the early extinguishment of corporate debt and impairment costs.
	The Company’s effective tax rate for the nine months ended September 30, 2012 was a provision of 7.4%. Such rate differed from the Federal statutory rate of 35.0% primarily due to an effective settlement of a $128 million unrecognized tax benefit for pre-Separation taxes, partially offset by the treatment of a portion of the expenses for the early extinguishment of corporate debt.

	Commitments and Contingencies
	Contingencies
	In connection with the Company’s 2006 separation into four independent companies (the “Separation”), the Company completed the spin-offs of Realogy Corporation (“Realogy”) and Wyndham Worldwide Corporation (“Wyndham”) on July 31, 2006 and completed the sale of Travelport, Inc. (“Travelport”) on August 23, 2006. In connection with the spin-offs of Realogy and Wyndham, the Company entered into a Separation Agreement, pursuant to which Realogy assumed 62.5% and Wyndham assumed 37.5% of certain contingent and other corporate liabilities of the Company or its subsidiaries, which are not primarily related to any of the respective businesses of Realogy, Wyndham, Travelport and/or the Company’s vehicle rental operations, and in each case incurred or allegedly incurred on or prior to the Separation (“Assumed Liabilities”). Realogy is entitled to receive 62.5% and Wyndham is entitled to receive 37.5% of the proceeds from certain contingent corporate assets of the Company, which are not primarily related to any of the respective businesses of Realogy, Wyndham, Travelport and/or the Company’s vehicle rental operations, arising or accrued on or prior to the Separation (“Assumed Assets”). Additionally, if Realogy or Wyndham were to default on its payment of costs or expenses to the Company related to any Assumed Liabilities, the Company would be responsible for 50% of the defaulting party’s obligation. In such event, the Company would be allowed to use the defaulting party’s share of the proceeds of any Assumed Assets as a right of offset.
	The Company does not believe that the impact of any resolution of contingent liabilities constituting Assumed Liabilities should result in a material liability to the Company in relation to its consolidated financial position or liquidity, as Realogy and Wyndham each have agreed to assume responsibility for these liabilities.
	The Company is also named in various litigation that is primarily related to the businesses of its former subsidiaries, including Realogy, Wyndham and Travelport and their current or former subsidiaries. The Company is entitled to indemnification from such entities under the Separation Agreement for any liability resulting from such litigation.
	In accordance with the terms of the Separation Agreement, Realogy posted a letter of credit in April 2007 for the benefit of the Company to cover its estimated share of the Assumed Liabilities discussed above, subject to adjustment, although there can be no assurance that such letter of credit will be sufficient or effective to cover Realogy’s actual obligations if and when they arise.
	In October 2009, a judgment was entered against the Company for damages related to breach of contract in Alaska Rent A Car, Inc. v. Cendant Corp., et al., in the United States District Court for the District of Alaska, which court subsequently amended the judgment to add amounts for pre-judgment interest and attorneys’ fees.  This proceeding, which began in 2003, concluded in September 2013, commensurate with the Company’s payment of the full amount of the judgment.  While the Company is continuing to pursue its appeal, it does not consider such appeal to be material to the Company’s financial condition.
	Additionally, the Company is also involved in claims, legal proceedings and governmental inquiries related to its vehicle rental operations, including, among others, contract and licensee disputes, wage-and-hour claims, competition matters, insurance claims, intellectual property claims and other regulatory, environmental, commercial and tax matters. Litigation is inherently unpredictable and, although the Company believes that its accruals are adequate and/or that it has valid defenses in these matters, unfavorable resolutions could occur, which could materially impact the Company’s financial position, results of operations or cash flows.
	Commitments to Purchase Vehicles
	The Company maintains agreements with vehicle manufacturers under which the Company has agreed to purchase approximately $4.4 billion of vehicles from manufacturers over the next 12 months. The majority of these commitments are subject to the vehicle manufacturers’ satisfying their obligations under their respective repurchase and guaranteed depreciation agreements. The purchase of such vehicles is financed primarily through the issuance of vehicle-backed debt and cash received upon the disposition of vehicles.
	Other Purchase Commitments
	In the normal course of business, the Company makes various commitments to purchase other goods or services from specific suppliers, including those related to capital expenditures. The purchase commitments made by the Company as of September 30, 2013 aggregate approximately $168 million. These purchase obligations extend through 2018.
	Concentrations
	Concentrations of credit risk at September 30, 2013 include (i) risks related to the Company’s repurchase and guaranteed depreciation agreements with car manufacturers, including Ford Motor Company, General Motors Company, Chrysler Group LLC, PSA Peugeot Citroën, Volkswagen Group, Fiat Group Automobiles S.p.A., BMW Group, Kia Motors America, Toyota Motor Corporation, Subaru of America, Inc., and Diamler AG, and primarily with respect to receivables for program cars that have been disposed but for which the Company has not yet received payment from the manufacturers and (ii) risks related to Realogy and Wyndham, including receivables of $61 million and $38 million, respectively, related to certain contingent, income tax and other corporate liabilities assumed by Realogy and Wyndham in connection with the Separation.
	Other Guarantees
	The Company has provided certain guarantees to, or for the benefit of, subsidiaries of Realogy, Wyndham and Travelport, which, as previously discussed, were disposed in 2006. These guarantees relate primarily to various real estate operating leases. The maximum potential amount of future payments that the Company may be required to make under the guarantees relating to these leases is estimated to be approximately $59 million, the majority of which expire by the end of 2015. At September 30, 2013, the liability recorded by the Company in connection with these guarantees was approximately $2 million.

Stock-Based Compensation	9 Months Ended

Stock-Based Compensation	'
	Stock-Based Compensation
	The Company records compensation expense for all stock-based awards based on the estimated fair value of the award at the grant date, which is recognized over the vesting period. The Company recorded stock-based compensation expense of $5 million and $4 million ($3 million and $2 million, net of tax) during the three months ended September 30, 2013 and 2012, respectively, and $14 million and $12 million ($9 million and $7 million, net of tax), during the nine months ended September 30, 2013 and 2012, respectively, related to stock-based awards that were granted by the Company.
	The Company applies the direct method and tax law ordering approach to calculate the tax effects of stock-based compensation. In jurisdictions with net operating loss carryforwards, tax deductions for exercises of stock options and vesting of restricted stock units in 2013 and 2012 did not generate a cash benefit. Approximately $13 million of incremental tax benefits will be recorded in additional paid-in capital when realized in these jurisdictions.
	During the nine months ended September 30, 2013, the Company granted the following stock-based awards under the Amended and Restated 2007 Equity and Incentive Plan:
	•	25,000 time-based restricted cash units (“RCUs”) and 87,000 market-vesting restricted cash units (“MCUs”); and
	•	637,000 time-based restricted stock units (“RSUs”), 396,000 performance-based restricted stock units (“PSUs”), and 87,000 market-vesting restricted stock units (“MSUs”).
	Restricted Cash Unit Awards
	The terms of the RCUs generally provide for vesting on the second anniversary of the grant date, subject to continued employment, and for settlement on the third anniversary of the grant date. The fair value of the RCUs was based on the Company’s stock price of $21.20 on the grant date.
	The terms of the MCUs generally provide for vesting of all or a portion of such units on the third anniversary of the grant date, subject to the attainment of performance goals based on total shareholder return over the vesting period in comparison to a specified market index (“TSR”). On the grant date, these units had a fair market value of $17.14, which was calculated using a Monte Carlo simulation model, based on the expected cash payout.
	The amount payable in respect of the RCUs and MCUs will be based on the Company’s average closing stock price over a specified number of trading days at the time of settlement. At September 30, 2013, the Company had 268,000 time-based and market-vesting restricted cash units outstanding with a weighted average contractual life of 1.6 years.
	Restricted Stock Unit Awards
	The terms of substantially all of the RSUs provide for vesting ratably on the first three anniversaries of the grant date, subject to continued employment. The weighted-average fair value of the RSUs of $21.77 was based on the Company’s closing stock price on the date of grant.
	The terms of the PSUs generally provide for vesting of a substantial majority of such units (or a portion thereof) on the third anniversary of the grant date, subject to attainment of certain performance goals based on Adjusted EBITDA, subject to certain further adjustments, with full vesting permitted on such anniversary if goals based on TSR are also achieved.
	The terms of the MSUs generally provide for vesting of all or a portion of such units on the third anniversary of the grant date, subject to the attainment of performance goals based on TSR.
	The Company determined the weighted-average fair value of performance-based and market-vesting restricted stock units granted in the nine months ended September 30, 2013 and 2012 using a Monte Carlo simulation model. The weighted-average fair value of the PSUs and MSUs granted in the nine months ended September 30, 2013, was estimated to be $20.67 and $17.14, respectively. The weighted-average fair value of the Company’s market-vesting restricted stock units issued in the nine months ended September 30, 2012 was estimated to be $10.92. The assumptions used to estimate the weighted-average fair value of the performance-based and market-vesting awards issued during the nine months ended September 30, 2013 and the market-vesting awards issued in the nine months ended September 30, 2012 were as follows:
		Nine Months Ended
		September 30,
		2013		2012
	Expected volatility of stock price	43%		50%
	Risk-free interest rate	0.39%		0.30% - 0.42%
	Expected term of awards	3 years		2 1/2 - 3 years
	Dividend yield	0.00%		0.00%
	The activity related to the Company’s time-based, performance-based and market-vesting restricted stock units (collectively, solely for purposes of the table below, “RSUs”), and stock options consisted of:

	(a)	During the nine months ended September 30, 2013, 438,000 market-vesting restricted stock units and 676,000 time-based restricted stock units vested. Stock options exercised during the nine months ended September 30, 2013 had an intrinsic value of $18 million.
	(b)	As of September 30, 2013, the Company’s outstanding RSUs had an aggregate intrinsic value of $99 million; aggregate unrecognized compensation expense related to RSUs amounted to $32 million; and the balance of RSUs at September 30, 2013, consists of 1,358,000 related to time-based awards and 2,078,000 related to market-vesting and performance-based awards. Approximately 1,000 time-based restricted stock units are eligible to vest in 2013, if applicable service criteria are satisfied. No market-vesting restricted stock units are eligible to vest in 2013.

	Segment Information
	The reportable segments presented below represent the Company’s operating segments for which separate financial information is available and is utilized on a regular basis by its chief operating decision maker, the Company’s chief executive officer, to assess performance and to allocate resources. In identifying its reportable segments, the Company also considers the nature of services provided by its operating segments, the geographical areas in which the segments operate and other relevant factors. The Company aggregates certain operating segments into its reportable segments. Management evaluates the operating results of each of its reportable segments based upon revenue and “Adjusted EBITDA”, which is defined as income from continuing operations before non-vehicle related depreciation and amortization, any impairment charge, transaction-related costs, non-vehicle related interest and income taxes. The Company’s presentation of Adjusted EBITDA may not be comparable to similarly-titled measures used by other companies.

Basis Of Presentation And Recently Issued Accounting Pronouncements [Abstract]	'
Basis of Presentation	'
	Basis of Presentation
	Avis Budget Group, Inc. provides car and truck rentals and ancillary services to businesses and consumers worldwide. The accompanying unaudited Consolidated Condensed Financial Statements include the accounts and transactions of Avis Budget Group, Inc. and its subsidiaries (“Avis Budget”), as well as entities in which Avis Budget directly or indirectly has a controlling financial interest (collectively, the “Company”), and have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission for interim financial reporting.
	The Company operates the following business segments:
	•	North America—provides car rentals in the United States and vehicle rentals in Canada, as well as ancillary products and services, and operates the Company’s Zipcar car sharing business.
	•	International—provides, and licenses the Company’s brands to third parties for, vehicle rentals and ancillary products and services primarily in Europe, the Middle East, Asia, Africa, South America, Central America, the Caribbean, Australia and New Zealand.
	•	Truck Rental—provides truck rentals and ancillary products and services to consumers and commercial users in the United States.
	In presenting the Consolidated Condensed Financial Statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”), management makes estimates and assumptions that affect the amounts reported and related disclosures. Estimates, by their nature, are based on judgment and available information. Accordingly, actual results could differ from those estimates. In management’s opinion, the Consolidated Condensed Financial Statements contain all adjustments necessary for a fair presentation of interim results reported. The results of operations reported for interim periods are not necessarily indicative of the results of operations for the entire year or any subsequent interim period. These financial statements should be read in conjunction with the Company’s 2012 Annual Report on Form 10-K and Form 10-K/A.
Vehicle Programs	'
	Vehicle Programs.  The Company presents separately the financial data of its vehicle programs. These programs are distinct from the Company’s other activities since the assets under vehicle programs are generally funded through the issuance of debt that is collateralized by such assets. The income generated by these assets is used, in part, to repay the principal and interest associated with the debt. Cash inflows and outflows relating to the acquisition of such assets and the principal debt repayment or financing of such assets are classified as activities of the Company’s vehicle programs. The Company believes it is appropriate to segregate the financial data of its vehicle programs because, ultimately, the source of repayment of such debt is the realization of such assets.
Transaction-related Costs	'
	Transaction-related Costs. The Company completed the acquisition of Zipcar on March 14, 2013 and the acquisition of Payless Car Rental ("Payless") on July 15, 2013. During the three and nine months ended September 30, 2013, transaction-related costs primarily include expenses related to the integration of Avis Europe’s operations with those of the Company and costs related to the acquisition and integration of Zipcar and Payless. In the three and nine months ended September 30, 2012, transaction-related costs primarily included expenses related to the integration of Avis Europe’s operations with the Company’s.
Foreign-currency Transactions	'
	Currency Transactions. The Company records the gain or loss of foreign-currency transactions on certain intercompany loans and gain or loss on intercompany loan hedges within interest expense related to corporate debt, net. During the three and nine months ended September 30, 2013, the Company recorded losses of $1 million and $8 million, respectively, on such items. In the three and nine months ended September 30, 2012, the Company recorded losses of $3 million and $12 million, respectively, on such items.
New Accounting Pronouncements, Policy [Policy Text Block]	'
	Adoption of New Accounting Standards
	On January 1, 2013, as a result of the issuance of a new accounting pronouncement, the Company adopted, as required, Accounting Standards Update No. 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income,” which requires companies to disclose additional information about amounts reclassified out of accumulated other comprehensive income by component. The adoption of this pronouncement resulted in incremental disclosure about activity and amounts reclassified out of accumulated other comprehensive income.
