	United Rentals, Inc. (“Holdings,” “URI” or the “Company”) 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 shareholder.
	We rent equipment to a diverse customer base that includes construction and industrial companies, manufacturers, utilities, municipalities, homeowners and government entities 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.
	On April 30, 2012 (“the acquisition date”), we acquired 100 percent of the outstanding common shares and voting interest of RSC Holdings Inc. (“RSC”). RSC 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 results of RSC's operations have been included in our condensed consolidated financial statements since the acquisition date. Our total revenues for the nine months ended September 30, 2013 were $3,617, while our pro forma total revenues for the nine months ended September 30, 2012, comprised of United Rentals and RSC historic revenues, were $3,415.
	We have prepared the accompanying unaudited condensed consolidated financial statements in accordance with the accounting policies described in our annual report on Form 10-K for the year ended December 31, 2012 (the “2012 Form 10-K”) and the interim reporting requirements of Form 10-Q. Accordingly, certain information and note disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted. These unaudited condensed consolidated financial statements should be read in conjunction with the 2012 Form 10-K.
	In our opinion, all adjustments, consisting only of normal recurring adjustments, which are necessary for a fair presentation of financial condition, operating results and cash flows for the interim periods presented have been made. Interim results of operations are not necessarily indicative of the results of the full year.

Segment Information	Segment Information
	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 construction, infrastructure, industrial and homeowner equipment and related services and activities. The general rentals segment’s customers include construction and industrial companies, manufacturers, utilities, municipalities, homeowners and government entities. The general rentals segment comprises 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 and related services. The trench safety, power and HVAC segment is comprised of the Trench Safety region, which rents trench safety equipment such as trench shields, aluminum hydraulic shoring systems, slide rails, crossing plates, construction lasers and line testing equipment for underground work, and the Power and HVAC region, which rents power and HVAC equipment such as portable diesel generators, electrical distribution equipment, and temperature control equipment including heating and cooling equipment. 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 and allocates resources. We evaluate segment performance based on segment equipment rentals gross profit.

Restructuring and Related Activities [Abstract]
Restructuring and Asset Impairment Charges	Restructuring and Asset Impairment Charges
	Closed Restructuring Program
	Between 2008 and 2011 and in recognition of the very challenging economic environment, we were intensely focused on reducing our operating costs. During this period, 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. For the nine months ended September 30, 2013, the restructuring charges primarily reflected branch closure charges due to continuing lease obligations at vacant facilities.
	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 September 30, 2013, our employee headcount is approximately 11,700 and our branch network has 822 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 end of the restructuring period).
	The table below provides certain information concerning our restructuring charges for the nine months ended September 30, 2013:

	Asset Impairment Charges
	In addition to the restructuring charges discussed above, during the three and nine months ended September 30, 2013, we recorded asset impairment charges of $0 and $4, respectively, in our general rentals segment. During the three and nine months ended September 30, 2012, we recorded asset impairment charges of $10 and $13, respectively, in our general rentals segment. The asset 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.

Derivatives

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 September 30, 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 condensed consolidated statements of income during the period in which the changes in fair value occur.
	We are exposed to certain risks related to our ongoing business operations. During the nine months ended September 30, 2013, the primary risks we managed using derivative instruments were diesel price risk and foreign currency exchange rate risk. At September 30, 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 nine months ended September 30, 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 September 30, 2013 and December 31, 2012, 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 represented derivative instruments not designated as hedging instruments.
	Fixed Price Diesel Swaps
	The fixed price swap contracts on diesel purchases that were outstanding at September 30, 2013 were designated and qualify as cash flow hedges and the effective portion of the 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 condensed consolidated statements of income during the current period. As of September 30, 2013, we had outstanding fixed price swap contracts covering 7.3 million gallons of diesel which will be purchased throughout 2013 and 2014.
	Foreign Currency Forward Contracts
	The forward contracts to purchase Canadian dollars, which were all settled as of September 30, 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 condensed consolidated statements of income during the period in which the changes in fair value occurred. During the three and nine months ended September 30, 2013, forward contracts were used to purchase $155 and $336 Canadian dollars, respectively, representing the total amount due at maturity for certain Canadian dollar denominated intercompany loans that were settled during the three and nine months ended September 30, 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 September 30, 2013 and December 31, 2012, less than $1 was reflected in prepaid expenses and other assets, accrued expenses and other liabilities, and accumulated other comprehensive income in our condensed consolidated balance sheets associated with the outstanding fixed price swap contracts that were designated and qualify as cash flow hedges.
	The effect of our derivative instruments on our condensed consolidated statements of income for the three and nine months ended September 30, 2013 and 2012 was as follows:

These amounts are reflected, net of cash received from the counterparties to the fixed price swaps, in operating cash flows in our condensed consolidated statement of cash flows.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements
	We account for certain assets and liabilities at fair value. We 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.
	Level 2- Observable inputs other than quoted prices in active markets for identical assets and liabilities include:
	a)	quoted prices for similar assets in active markets;
	b)	quoted prices for identical or similar assets in inactive markets;
	c)	inputs other than quoted prices that are observable for the asset;
	d)	inputs that are derived principally from or corroborated by observable market data by correlation or other means.
	If the asset has a specified (contractual) term, the Level 2 input must be observable for substantially the full term of the asset.
	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 September 30, 2013 and December 31, 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 September 30, 2013 and December 31, 2012, less than $1 was reflected in prepaid expenses and other assets, and accrued expenses and other liabilities in our condensed consolidated balance sheets, reflecting the fair values of the fixed price diesel swaps contracts. As discussed in note 4 to the condensed 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 September 30, 2013, we have fixed price swap contracts that mature throughout 2013 and 2014 covering 7.3 million gallons of diesel which we will buy at the average contract price of $3.88 per gallon, while the average forward price for the hedged gallons was $3.87 per gallon as of September 30, 2013.
	Fair Value of Financial Instruments
	The carrying amounts reported in our condensed 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 ABL facility, accounts receivable securitization facility and capital leases approximate their book values as of September 30, 2013 and December 31, 2012. The estimated fair values of our financial instruments as of September 30, 2013 and December 31, 2012 have been calculated based upon available market information, and are presented below by level in the fair value hierarchy:
		September 30, 2013				December 31, 2012
		Carrying		Fair		Carrying		Fair
		Amount		Value		Amount		Value
	Level 1:
	Subordinated convertible debentures	$	—	$	—	$	55	$	63
	Senior and senior subordinated notes	5,383		5,773		5,387		5,881
	Level 2:
	4 percent Convertible Senior Notes (1)	134		146		137		155
	___________________
	-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 6.8 percent.

	___________________
	-1	In February 2013, we amended our accounts receivable securitization facility to increase the facility size from $475 to $550. An additional purchaser was also added to the facility, and the facility was not otherwise amended. In September 2013, we renewed the facility which now expires on September 18, 2014. At September 30, 2013, $29 was available under our accounts receivable securitization facility. The interest rate applicable to the accounts receivable securitization facility was 0.9 percent at September 30, 2013. During the nine months ended September 30, 2013, the monthly average amount outstanding under the accounts receivable securitization facility, including the former facility and the amended facility, was $443, and the weighted-average interest rate thereon was 0.8 percent. The maximum month-end amount outstanding under the accounts receivable securitization facility, including the former facility and the amended facility, during the nine months ended September 30, 2013 was $493. Borrowings under the accounts receivable securitization facility 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. As of September 30, 2013, there were $491 of receivables, net of applicable reserves, in the collateral pool.
	-2	In June 2013, our ABL facility was amended to reduce the minimum borrowing period and to increase the number of available loan tranches. At September 30, 2013, $370 was available under our ABL facility, net of $52 of letters of credit. The interest rate applicable to the ABL facility was 2.2 percent at September 30, 2013. During the nine months ended September 30, 2013, the monthly average amount outstanding under the ABL facility was $1,167, and the weighted-average interest rate thereon was 2.3 percent. The maximum month-end amount outstanding under the ABL facility during the nine months ended September 30, 2013 was $1,478.
	-3	The difference between the September 30, 2013 carrying value of the 4 percent Convertible Senior Notes and the $156 principal amount reflects the $22 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 Senior Notes were redeemable at September 30, 2013, an amount equal to the $22 unamortized portion of the original issue discount is separately classified in our condensed consolidated balance sheets and referred to as “temporary equity.” Based on the price of our common stock during the third quarter of 2013, holders of the 4 percent Convertible Senior Notes have the right to redeem the notes during the fourth quarter of 2013 at a conversion price of $11.11 per share of common stock. Since October 1, 2013 (the beginning of the fourth quarter), none of the 4 percent Convertible Senior Notes were redeemed.
	-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 nine months ended September 30, 2013, an aggregate of $55 of QUIPS was redeemed. As of September 30, 2013, there were no QUIPS outstanding. In connection with these redemptions, during the nine months ended September 30, 2013, we retired $55 principal amount of our subordinated convertible debentures and recognized a loss of $2, inclusive of the write-off of capitalized debt issuance costs. This loss is reflected in interest expense-subordinated convertible debentures in our condensed consolidated statements of income. As of September 30, 2013, there were no subordinated convertible debentures outstanding. Total debt at December 31, 2012 excludes $55 of these Debentures, which were separately classified in our condensed consolidated balance sheets and referred to as “subordinated convertible debentures.” The subordinated convertible debentures reflected the obligation to our subsidiary that issued the QUIPS. As of December 31, 2012, this subsidiary was not consolidated in our financial statements because we were not the primary beneficiary of the Trust. As of September 30, 2013, the Trust was liquidated.
	-5	As of September 30, 2013, our short-term debt primarily reflects $462 of borrowings under our accounts receivable securitization facility and $134 of 4 percent Convertible Senior Notes. The 4 percent Convertible Senior Notes mature in 2015, but are reflected as short-term debt because they are redeemable at September 30, 2013.
	Convertible Note Hedge Transactions
	In connection with the November 2009 issuance of $173 aggregate principal amount of 4 percent Convertible Senior Notes, 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 condensed consolidated statements of stockholders’ equity. The convertible note hedge transactions cover, subject to anti-dilution adjustments, 14.0 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 Senior 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 Senior 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 $55.00 or $60.00 per share, assuming an effective conversion price of $15.56 per share, on a net basis, we would issue 10.1 million or 10.4 million shares, respectively.
	Loan Covenants and Compliance
	As of September 30, 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.
	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 ABL facility. Since the October 2011 amendment of the ABL facility and through September 30, 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 amended ABL facility, the fixed charge coverage ratio and the senior secured leverage ratio under the amended ABL facility will only apply in the future if availability under the amended ABL facility falls below the greater of 10 percent of the maximum revolver amount under the amended 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.

	In addition to the disclosures provided in note 15 to our consolidated financial statements for the year ended December 31, 2012 filed on Form 10-K on January 23, 2013, we are also 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 condition, results of operations or cash flows.

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. Diluted earnings per share for the nine months ended September 30, 2013 and 2012 excludes the impact of approximately 0.4 million and 1.9 million common stock equivalents, respectively, since the effect of including these securities would be anti-dilutive.

Condensed Consolidating Financial Information of Guarantor Subsidiaries	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. The condensed consolidating financial information of Parent and its subsidiaries is as follows:

	-1	In February 2013, we amended our accounts receivable securitization facility to increase the facility size from $475 to $550. An additional purchaser was also added to the facility, and the facility was not otherwise amended. In September 2013, we renewed the facility which now expires on September 18, 2014. At September 30, 2013, $29 was available under our accounts receivable securitization facility. The interest rate applicable to the accounts receivable securitization facility was 0.9 percent at September 30, 2013. During the nine months ended September 30, 2013, the monthly average amount outstanding under the accounts receivable securitization facility, including the former facility and the amended facility, was $443, and the weighted-average interest rate thereon was 0.8 percent. The maximum month-end amount outstanding under the accounts receivable securitization facility, including the former facility and the amended facility, during the nine months ended September 30, 2013 was $493. Borrowings under the accounts receivable securitization facility 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. As of September 30, 2013, there were $491 of receivables, net of applicable reserves, in the collateral pool.
	-2	In June 2013, our ABL facility was amended to reduce the minimum borrowing period and to increase the number of available loan tranches. At September 30, 2013, $370 was available under our ABL facility, net of $52 of letters of credit. The interest rate applicable to the ABL facility was 2.2 percent at September 30, 2013. During the nine months ended September 30, 2013, the monthly average amount outstanding under the ABL facility was $1,167, and the weighted-average interest rate thereon was 2.3 percent. The maximum month-end amount outstanding under the ABL facility during the nine months ended September 30, 2013 was $1,478.
	-3	The difference between the September 30, 2013 carrying value of the 4 percent Convertible Senior Notes and the $156 principal amount reflects the $22 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 Senior Notes were redeemable at September 30, 2013, an amount equal to the $22 unamortized portion of the original issue discount is separately classified in our condensed consolidated balance sheets and referred to as “temporary equity.” Based on the price of our common stock during the third quarter of 2013, holders of the 4 percent Convertible Senior Notes have the right to redeem the notes during the fourth quarter of 2013 at a conversion price of $11.11 per share of common stock. Since October 1, 2013 (the beginning of the fourth quarter), none of the 4 percent Convertible Senior Notes were redeemed.
	-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 nine months ended September 30, 2013, an aggregate of $55 of QUIPS was redeemed. As of September 30, 2013, there were no QUIPS outstanding. In connection with these redemptions, during the nine months ended September 30, 2013, we retired $55 principal amount of our subordinated convertible debentures and recognized a loss of $2, inclusive of the write-off of capitalized debt issuance costs. This loss is reflected in interest expense-subordinated convertible debentures in our condensed consolidated statements of income. As of September 30, 2013, there were no subordinated convertible debentures outstanding. Total debt at December 31, 2012 excludes $55 of these Debentures, which were separately classified in our condensed consolidated balance sheets and referred to as “subordinated convertible debentures.” The subordinated convertible debentures reflected the obligation to our subsidiary that issued the QUIPS. As of December 31, 2012, this subsidiary was not consolidated in our financial statements because we were not the primary beneficiary of the Trust. As of September 30, 2013, the Trust was liquidated.
	-5	As of September 30, 2013, our short-term debt primarily reflects $462 of borrowings under our accounts receivable securitization facility and $134 of 4 percent Convertible Senior Notes. The 4 percent Convertible Senior Notes mature in 2015, but are reflected as short-term debt because they are redeemable at September 30, 2013.

These amounts are reflected, net of cash received from the counterparties to the fixed price swaps, in operating cash flows in our condensed consolidated statement of cash flows.
[3]	Insignificant amounts were reflected in our condensed consolidated statement of cash flows associated with the forward contracts to purchase Canadian dollars, as the cash impact of the gains/losses recognized on the derivatives were offset by the gains/losses recognized on the hedged items.

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 nine months ended September 30, 2013, an aggregate of $55 of QUIPS was redeemed. As of September 30, 2013, there were no QUIPS outstanding. In connection with these redemptions, during the nine months ended September 30, 2013, we retired $55 principal amount of our subordinated convertible debentures and recognized a loss of $2, inclusive of the write-off of capitalized debt issuance costs. This loss is reflected in interest expense-subordinated convertible debentures in our condensed consolidated statements of income. As of September 30, 2013, there were no subordinated convertible debentures outstanding. Total debt at December 31, 2012 excludes $55 of these Debentures, which were separately classified in our condensed consolidated balance sheets and referred to as “subordinated convertible debentures.” The subordinated convertible debentures reflected the obligation to our subsidiary that issued the QUIPS. As of December 31, 2012, this subsidiary was not consolidated in our financial statements because we were not the primary beneficiary of the Trust. As of September 30, 2013, the Trust was liquidated.

In February 2013, we amended our accounts receivable securitization facility to increase the facility size from $475 to $550. An additional purchaser was also added to the facility, and the facility was not otherwise amended. In September 2013, we renewed the facility which now expires on September 18, 2014. At September 30, 2013, $29 was available under our accounts receivable securitization facility. The interest rate applicable to the accounts receivable securitization facility was 0.9 percent at September 30, 2013. During the nine months ended September 30, 2013, the monthly average amount outstanding under the accounts receivable securitization facility, including the former facility and the amended facility, was $443, and the weighted-average interest rate thereon was 0.8 percent. The maximum month-end amount outstanding under the accounts receivable securitization facility, including the former facility and the amended facility, during the nine months ended September 30, 2013 was $493. Borrowings under the accounts receivable securitization facility 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. As of September 30, 2013, there were $491 of receivables, net of applicable reserves, in the collateral pool.

[3]

In June 2013, our ABL facility was amended to reduce the minimum borrowing period and to increase the number of available loan tranches. At September 30, 2013, $370 was available under our ABL facility, net of $52 of letters of credit. The interest rate applicable to the ABL facility was 2.2 percent at September 30, 2013. During the nine months ended September 30, 2013, the monthly average amount outstanding under the ABL facility was $1,167, and the weighted-average interest rate thereon was 2.3 percent. The maximum month-end amount outstanding under the ABL facility during the nine months ended September 30, 2013 was $1,478.

[4]

The difference between the September 30, 2013 carrying value of the 4 percent Convertible Senior Notes and the $156 principal amount reflects the $22 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 Senior Notes were redeemable at September 30, 2013, an amount equal to the $22 unamortized portion of the original issue discount is separately classified in our condensed consolidated balance sheets and referred to as “temporary equity.” Based on the price of our common stock during the third quarter of 2013, holders of the 4 percent Convertible Senior Notes have the right to redeem the notes during the fourth quarter of 2013 at a conversion price of $11.11 per share of common stock. Since October 1, 2013 (the beginning of the fourth quarter), none of the 4 percent Convertible Senior Notes were redeemed.

[5]

As of September 30, 2013, our short-term debt primarily reflects $462 of borrowings under our accounts receivable securitization facility and $134 of 4 percent Convertible Senior Notes. The 4 percent Convertible Senior Notes mature in 2015, but are reflected as short-term debt because they are redeemable at September 30, 2013.
