Notes to Consolidated Financial Statements (Unaudited) (Millions, Except Share Amounts)    

NOTE A - Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2012 are not necessarily indicative of the results that may be expected for the year ending December 31, 2012. For further information, refer to the consolidated financial statements and footnotes included in PACCAR Inc’s (the Company) Annual Report on Form 10-K for the year ended December 31, 2011.

Earnings per Share: Basic earnings per common share are computed by dividing earnings by the weighted average number of common shares outstanding, plus the effect of any participating securities. Diluted earnings per common share are computed assuming that all potentially dilutive securities are converted into common shares under the treasury stock method. The dilutive and antidilutive options are shown separately in the table below.

	Three Months Ended September 30				Nine Months Ended September 30
	2012		2011		2012		2011
Additional shares		689,000		876,000		746,000		1,211,000
Antidilutive options		2,497,000		1,697,000		2,561,000		770,000

New Accounting Pronouncements: In May 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs. While many of the amendments are clarifications to the existing guidance and are intended to align U.S. GAAP and International Financial Reporting Standards (IFRS), the ASU changes some fair value measurement principles and disclosure requirements. The Company adopted ASU 2011-04 in the first quarter of 2012; the implementation of this amendment resulted in additional disclosures (see note J), but did not have a significant impact on the Company’s consolidated financial statements.

The FASB issued ASU 2011-05, Presentation of Comprehensive Income, in June 2011, which was subsequently amended by ASU 2011-12 in December 2011. The new guidance requires entities to present components of net income and comprehensive income in either a combined financial statement or in two separate but consecutive statements of net income and comprehensive income. The Company adopted ASU 2011-05 as amended in the first quarter of 2012 and has elected to present components of net income combined with a total for comprehensive income in a single continuous statement in its consolidated interim financial statements. The Company is currently evaluating which method to adopt in the consolidated annual financial statements.

NOTE B - Investments in Marketable Debt Securities

The Company’s investments in marketable debt securities are classified as available-for-sale. These investments are stated at fair value with any unrealized gains or losses, net of tax, included as a component of accumulated other comprehensive income (loss).

The Company utilizes third-party pricing services for all of its marketable debt security valuations. The Company reviews the pricing methodology used by the third-party pricing services including the manner employed to collect market information. On a periodic basis, the Company also performs review and validation procedures on the pricing information received from the third-party providers. These procedures help ensure that the fair value information used by the Company is determined in accordance with applicable accounting guidance.

Notes to Consolidated Financial Statements (Unaudited) (Millions, Except Share Amounts)    

The Company evaluates its investment in marketable debt securities at the end of each reporting period to determine if a decline in fair value is other than temporary. Realized losses are recognized upon management’s determination that a decline in fair value is other than temporary. The determination of other-than-temporary impairment is a subjective process, requiring the use of judgments and assumptions regarding the amount and timing of recovery. The Company reviews and evaluates its investments at least quarterly to identify investments that have indications of other-than-temporary impairments. It is reasonably possible that a change in estimate could occur in the near term relating to other-than-temporary impairment. Accordingly, the Company considers several factors when evaluating debt securities for other-than-temporary impairment, including whether the decline in fair value of the security is due to increased default risk for the specific issuer or market interest rate risk.

In assessing default risk, the Company considers the collectability of principal and interest payments by monitoring changes to issuers’ credit ratings, specific credit events associated with individual issuers as well as the credit ratings of any financial guarantor, and the extent and duration to which amortized cost exceeds fair value.

In assessing market interest rate risk, including benchmark interest rates and credit spreads, the Company considers its intent for selling the securities and whether it is more likely than not the Company will be able to hold these securities until the recovery of any unrealized losses.

Marketable debt securities at September 30, 2012 and December 31, 2011 consisted of the following:

At September 30, 2012	AMORTIZED COST		UNREALIZED GAINS		UNREALIZED LOSSES		FAIR VALUE
U.S. tax-exempt securities	$	299.7	$	2.6			$	302.3
U.S. corporate securities		27.9		.3				28.2
U.S. government and agency securities		1.2						1.2
Non-U.S. government securities		386.1		7.4				393.5
Non-U.S. corporate securities		150.3		1.1				151.4
Other debt securities		78.6		.7				79.3
	$	943.8	$	12.1			$	955.9
At December 31, 2011	AMORTIZED COST		UNREALIZED GAINS		UNREALIZED LOSSES		FAIR VALUE
U.S. tax-exempt securities	$	291.9	$	2.6	$	.1	$	294.4
U.S. corporate securities		27.4		.3		.2		27.5
U.S. government and agency securities		1.9						1.9
Non-U.S. government securities		361.2		6.0		.1		367.1
Non-U.S. corporate securities		148.0		.5		.2		148.3
Other debt securities		70.3		.6				70.9
	$	900.7	$	10.0	$	.6	$	910.1

The cost of marketable debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Amortization, accretion, interest and dividend income and realized gains and losses are included in investment income. The cost of securities sold is based on the specific identification method. The proceeds from sales and maturities of marketable securities for the nine months ended September 30, 2012 were $445.8. Gross realized gains were $1.9 and $2.2 and gross realized losses were $.1 and $.6 for the nine months ended September 30, 2012 and 2011, respectively.

Notes to Consolidated Financial Statements (Unaudited) (Millions, Except Share Amounts)    

The fair value of marketable debt securities that have been in an unrealized loss position for 12 months or greater at September 30, 2012 was $2.6 and the associated unrealized loss was $.01. At September 30, 2011, there were no marketable debt securities in an unrealized loss position for greater than 12 months.

For the investment securities in gross unrealized loss positions identified above, the Company does not intend to sell the investment securities, it is more likely than not that the Company will not be required to sell the investment securities before recovery of the unrealized losses, and the Company expects that the contractual principal and interest will be received on the investment securities. As a result, the Company recognized no other-than-temporary impairments during the periods presented.

Contractual maturities on marketable debt securities at September 30, 2012 were as follows:

Maturities:	AMORTIZED COST		FAIR VALUE
Within one year	$	326.6	$	328.3
One to five years		615.7		626.1
Six to ten years		.2		.2
More than ten years		1.3		1.3
	$	943.8	$	955.9

Marketable debt securities included $1.3 and $7.1 of variable rate demand obligations (VRDOs) at September 30, 2012 and December 31, 2011, respectively. VRDOs are debt instruments with long-term scheduled maturities which have interest rates that reset periodically.

NOTE C - Inventories

Inventories are stated at the lower of cost or market. Cost of inventories in the U.S. is determined principally by the last-in, first-out (LIFO) method. Cost of all other inventories is determined principally by the first-in, first-out (FIFO) method.

Inventories include the following:

	September 30 2012			December 31 2011
Finished products	$	486.3		$	436.2
Work in process and raw materials		597.6			439.6
		1,083.9			875.8
Less LIFO reserve		(168.3	)		(165.4	)
	$	915.6		$	710.4

Under the LIFO method of accounting (used for approximately 47% of September 30, 2012 inventories), an actual valuation can be made only at the end of each year based on year-end inventory levels and costs. Accordingly, interim valuations are based on management’s estimates of those year-end amounts.

NOTE D - Finance and Other Receivables

Finance and other receivables include the following:

	September 30 2012			December 31 2011
Loans	$	3,554.8		$	3,114.8
Retail direct financing leases		2,401.7			2,187.8
Sales-type finance leases		857.9			795.8
Dealer wholesale financing		1,702.4			1,517.1
Accrued rents and other trade receivables		111.5			111.0
Unearned interest on finance leases		(356.2	)		(327.8	)
		8,272.1			7,398.7
Less allowance for losses:
Loans and leases		(120.6	)		(118.5	)
Dealer wholesale financing		(12.4	)		(11.7	)
Accrued rents and other trade receivables		(6.1	)		(8.8	)
	$	8,133.0		$	7,259.7

Recognition of interest income and rental revenue is suspended (put on non-accrual status) when the receivable becomes more than 90 days past the contractual due date or earlier if some other event causes the Company to determine that collection is not probable. Accordingly, there were no finance receivables more than 90 days past due still accruing interest at September 30, 2012 or December 31, 2011. Recognition is resumed if the receivable becomes current by the payment of all amounts due under the terms of the existing contract and collection of remaining amounts is considered probable (if not contractually modified), or after the customer has made scheduled payments for three months and collection of remaining amounts is considered probable (if contractually modified). Payments received while the finance receivable is impaired or on non-accrual status are applied to interest and principal in accordance with the contractual terms.

Allowance for Credit Losses

The Company continuously monitors the payment performance of all its finance receivables. For large retail finance customers and dealers with wholesale financing, the Company regularly reviews their financial statements and makes site visits and phone contact as appropriate. If the Company becomes aware of circumstances that could cause those customers or dealers to face financial difficulty, whether or not they are past due, the customers are placed on a watch list.

The Company modifies loans and finance leases as a normal part of its Financial Services operations. The Company may modify loans and finance leases for commercial reasons or for credit reasons. Modifications for commercial reasons are changes to contract terms for customers that are not considered to be in financial difficulty. Modifications for credit reasons are changes to contract terms for customers considered to be in financial difficulty. The Company’s modifications typically result in granting more time to pay the contractual amounts owed and charging a fee and interest for the term of the modification.

When considering whether to modify customer accounts for credit reasons, the Company evaluates the creditworthiness of the customers and modifies those accounts that the Company considers likely to perform under the modified terms. When the Company modifies loans and finance leases for credit reasons and grants a concession, the modifications are classified as troubled debt restructurings (TDRs). The Company does not typically grant credit modifications for customers that do not meet minimum underwriting standards since the Company normally repossesses the financed equipment in these circumstances. When such modifications do occur, they are considered TDRs.

Notes to Consolidated Financial Statements (Unaudited) (Millions, Except Share Amounts)    

On average, modifications extended contractual terms by approximately eight months in 2012 and nine months in 2011 and did not have a significant effect on the weighted average term or interest rate of the total portfolio at September 30, 2012 and December 31, 2011.

The Company has developed a systematic methodology for determining the allowance for credit losses for its two portfolio segments, retail and wholesale. The retail segment consists of retail loans and direct and sales-type finance leases, net of unearned interest. The wholesale segment consists of wholesale financing loans to dealers that are collateralized by trucks and other collateral. The wholesale segment generally has less risk than the retail segment. Wholesale receivables generally are shorter in duration than retail receivables, and the Company requires monthly reporting of the wholesale dealer’s financial condition, conducts periodic audits of the trucks being financed and in many cases, obtains personal guarantees or other security such as dealership assets. In determining the allowance for credit losses, retail loans and finance leases are evaluated together since they relate to a similar customer base, their contractual terms require regular payment of principal and interest generally over 36 to 60 months and they are secured by the same type of collateral. The allowance for credit losses consists of both specific and general reserves.

The Company individually evaluates certain finance receivables for impairment. Finance receivables which are evaluated individually for impairment consist of all wholesale accounts and certain large retail accounts with past due balances or otherwise determined to be at a higher risk of loss. A finance receivable is impaired if it is considered probable the Company will be unable to collect all contractual interest and principal payments as scheduled. In addition, all retail loans and leases which have been classified as TDRs and all customer accounts over 90 days past due are considered impaired. All impaired accounts are on non-accrual status.

Impaired receivables are considered collateral dependent. Large balance retail and all wholesale impaired receivables are individually evaluated to determine the appropriate reserve for losses. The determination of reserves for large balance impaired receivables considers the fair value of the associated collateral. When the underlying collateral fair value exceeds the Company’s loss exposure, no reserve is recorded. Small balance impaired receivables with similar risk characteristics are evaluated as a separate pool to determine the appropriate reserve for losses using the historical loss information discussed below.

For finance receivables that are not individually impaired, the Company collectively evaluates and determines the general allowance for credit losses for both retail and wholesale receivables based on historical loss information, using past-due account data and current market conditions. Information used includes assumptions regarding the likelihood of collecting current and past-due accounts, repossession rates, the recovery rate on the underlying collateral based on used truck values and other pledged collateral or recourse. The Company has developed a range of loss estimates for each of its country portfolios based on historical experience, taking into account loss frequency and severity in both strong and weak truck market conditions. A projection is made of the range of estimated credit losses inherent in the portfolio from which an amount is determined as probable based on current market conditions and other factors impacting the creditworthiness of the Company’s borrowers and their ability to repay. After determining the appropriate level of the allowance for credit losses, the provision for losses on finance receivables is charged to income as necessary to reflect management’s estimate of incurred credit losses, net of recoveries, inherent in the portfolio.

In determining the fair value of the collateral, the Company uses a pricing model and categorizes the fair value as Level 2 in the hierarchy of fair value measurement. The pricing model is reviewed quarterly and updated as appropriate. The pricing model considers the make, model and year of the equipment as well as recent sales prices of comparable equipment through wholesale channels to the Company’s dealers (principal market). The fair value of the collateral also considers the overall condition of the equipment.

Accounts are charged-off against the allowance for credit losses when, in the judgment of management, they are considered uncollectable (generally upon repossession of the collateral). Typically the timing between the repossession and charge-off is not significant. In cases where repossession is delayed (e.g., for legal proceedings), the Company records partial charge-offs. The charge-off is determined by comparing the fair value of the collateral, less cost to sell, to the recorded investment.

The allowance for credit losses is summarized as follows:

Impaired Loans

The Company’s impaired loans are segregated by portfolio class. A portfolio class of receivables is a subdivision of a portfolio segment with similar measurement attributes and risk characteristics and common methods to monitor and assess credit risk. The Company’s retail segment is subdivided into the fleet and owner/operator classes. Fleet consists of retail accounts with customers operating more than five trucks. All others are owner/operator.

Substantially all impaired loans have a specific reserve and are summarized below. The impaired loans with specific reserve represent the unpaid principal loan balance.

Credit Quality

The Company’s customers are principally concentrated in the transportation industry in North America, Europe and Australia. On a geographic basis, there is a proportionate concentration of credit risk in each area. The Company retains as collateral a security interest in the related equipment.

At the inception of each contract, the Company considers the credit risk based on a variety of credit quality factors including; prior payment experience, customer financial information, credit-rating agency

- 13 -

PACCAR Inc – Form 10-Q

Notes to Consolidated Financial Statements (Unaudited) (Millions, Except Share Amounts)    

ratings, loan-to-value ratios and other internal metrics. On an ongoing basis, the Company monitors credit quality based on past-due status and collection experience as the Company has found a meaningful correlation between the past due status of customers and the risk of loss.

The Company has three credit quality indicators: performing, watch and at-risk. Performing accounts pay in accordance with the contractual terms and are not considered high risk. Watch accounts include accounts 31 to 90 days past due and large accounts that are performing but are considered to be high-risk. Watch accounts are not impaired. At-risk accounts are accounts that are impaired, including TDRs, accounts over 90 days past-due and other accounts on non-accrual status. The Company uses historical data and known trends to estimate default rates for each credit quality indicator. The tables below summarize the Company’s finance receivables by credit quality indicator and portfolio class.

At September 30, 2012	WHOLESALE		FLEET		OWNER / OPERATOR		TOTAL

Troubled Debt Restructurings

For the three and nine months ended September 30, 2012, the decrease in the recorded investment for loans and leases modified as TDRs was $.8 and $1.5, respectively, resulting in post-modification recorded investment of $14.5 and $45.9, respectively. At modification date, the pre-modification and post-modification recorded investment balances by portfolio class are as follows:

	Three Months Ended				Nine Months Ended
	September 30, 2012				September 30, 2012
	Recorded Investment				Recorded Investment
	Pre- Modification		Post- Modification		Pre- Modification		Post- Modification
Fleet	$	14.7	$	13.9	$	45.3	$	43.8
Owner / Operator		.6		.6		2.1		2.1

Owner / Operator		.7		.7		5.2		5.2
	$	4.1	$	4.1	$	29.7	$	29.5

The balance of TDRs was $44.0 at September 30, 2012 and $26.0 at December 31, 2011.

The recorded investment in finance receivables modified as TDRs during the previous twelve months that subsequently defaulted (i.e., became more than 30 days past-due) in the nine months ended September 30, 2012 was $7.7 and $.5 for fleet and owner/operator, respectively. Included in the $7.7 of fleet redefaults is $4.8 from one customer, for which the Company had a specific reserve of $1.8 as of September 30, 2012. The TDRs that subsequently defaulted did not significantly impact the Company’s allowance for credit losses at September 30, 2012.

Repossessions

When the Company determines that a past-due customer is not likely to meet its contractual commitments, the Company repossesses the vehicles which serve as collateral for loans, finance leases and equipment under operating lease. The Company records the repossessed vehicles as used truck inventory which is included in Financial Services other assets on the Consolidated Balance Sheets. The balance of repossessed inventory at September 30, 2012 and December 31, 2011 was $10.8 and $16.0, respectively. Proceeds from the sales of repossessed assets were $48.7 and $65.7 for the nine months ended September 30, 2012 and 2011, respectively. These amounts are included in proceeds from asset disposals on the Condensed Consolidated Statements of Cash Flows. Write-downs of repossessed equipment on operating leases are recorded as impairments and included in Financial Services depreciation and other expense on the Consolidated Statements of Comprehensive Income.

NOTE E - Product Support Liabilities

Product support liabilities are estimated future payments related to product warranties, optional extended warranties and repair and maintenance (R&M) contracts. The Company generally offers one-year warranties covering most of its vehicles and related aftermarket parts. Specific terms and conditions vary depending on the product and the country of sale. Optional extended warranty and

- 15 -

PACCAR Inc – Form 10-Q

Notes to Consolidated Financial Statements (Unaudited) (Millions, Except Share Amounts)    

R&M contracts can be purchased for periods which generally range up to five years. Warranty expenses and reserves are estimated and recorded at the time products or contracts are sold based on historical data regarding the source, frequency and cost of claims, net of any recoveries. Revenue from extended warranty contracts is deferred and recognized to income on a straight-line basis over the contract period. Warranty costs on these contracts are recognized as incurred. The Company periodically assesses the adequacy of its recorded liabilities and adjusts them as appropriate to reflect actual experience.

Changes in product support liabilities are summarized as follows:

	2012			2011
Balance at January 1	$	448.7		$	372.2
Cost accruals and revenue deferrals		234.6			219.1

Stock Compensation Plans

Stock-based compensation expense was $2.6 and $11.0 for the three and nine months ended September 30, 2012, respectively, and $2.6 and $11.1 for the three and nine months ended September 30, 2011, respectively. Realized tax benefits related to the excess of deductible amounts over expense recognized amounted to nil and $.8 for the three and nine months ended September 30, 2012, respectively, and nil and $.7 for the three and nine months ended September 30, 2011, respectively, and have been classified as a financing cash flow.

During the first three quarters of 2012, the Company issued 447,002 common shares under deferred and stock compensation arrangements.

NOTE G - Income Taxes

The effective income tax rate in the third quarter of 2012 was 32.4% an increase from 28.7% in the third quarter of 2011 due to a higher mix of foreign income in jurisdictions with higher tax rates. For the first nine months of 2012, the effective income tax rate was 32.5% an increase from 30.9% in the first nine months of 2011. The higher tax rate in the first nine months of 2012 primarily reflects an increased proportion of domestic income.

NOTE I - Derivative Financial Instruments

As part of its risk management strategy, the Company enters into derivative contracts to hedge exposures to fluctuations in interest rates and foreign currency exchange rates. Certain derivative instruments designated as either cash flow hedges or fair value hedges are subject to hedge accounting. Derivative instruments that are not subject to hedge accounting are held as economic hedges. The Company’s policies prohibit the use of derivatives for speculation or trading. At the inception of each hedge relationship, the Company documents its risk management objectives, procedures and accounting treatment.

The Company has elected not to offset derivative positions in the balance sheet with the same counterparty under the same master netting agreements. The Company is not required to post or receive collateral under these agreements. Exposure limits and minimum credit ratings are used to minimize the risks of counterparty default. The Company had no material exposures to default at September 30, 2012.

- 18 -

PACCAR Inc – Form 10-Q

Notes to Consolidated Financial Statements (Unaudited) (Millions, Except Share Amounts)    

The Company uses regression analysis to assess effectiveness of interest-rate contracts on a quarterly basis. For foreign-exchange contracts, the Company performs quarterly assessments to ensure that critical terms continue to match. All components of the derivative instrument’s gain or loss are included in the assessment of hedge effectiveness. Gains or losses on the ineffective portion of cash flow hedges are recognized currently in earnings. Hedge accounting is discontinued prospectively when the Company determines that a derivative financial instrument has ceased to be a highly effective hedge.

Interest-Rate Contracts: The Company enters into various interest-rate contracts, including interest-rate swaps and cross currency interest-rate swaps. Interest-rate swaps involve the exchange of fixed for floating rate or floating for fixed rate interest payments based on the contractual notional amounts in a single currency. Cross currency interest-rate swaps involve the exchange of notional amounts and interest payments in different currencies. The Company is exposed to interest-rate and exchange-rate risk caused by market volatility as a result of its borrowing activities. The objective of these contracts is to mitigate the fluctuations on earnings, cash flows and fair value of borrowings. Net amounts paid or received are reflected as adjustments to interest expense.

At September 30, 2012, the notional amount of the Company’s interest-rate contracts was $3,135.6. Notional maturities for all interest-rate contracts are $56.8 for the remainder of 2012, $716.9 for 2013, $1,342.8 for 2014, $775.4 for 2015, $39.3 for 2016 and $204.4 thereafter. The majority of these contracts are floating to fixed swaps that effectively convert an equivalent amount of commercial paper and other variable rate debt to fixed rates.

Foreign-Exchange Contracts: The Company enters into foreign-exchange contracts to hedge certain anticipated transactions and assets and liabilities denominated in foreign currencies, particularly the Canadian dollar, the euro, the British pound, the Australian dollar and the Mexican peso. The objective is to reduce fluctuations in earnings and cash flows associated with changes in foreign currency exchange rates. At September 30, 2012, the notional amount of the outstanding foreign-exchange contracts was $188.1. Foreign-exchange contracts mature within one year.

Fair Value Hedges

Changes in the fair value of derivatives designated as fair value hedges are recorded in earnings together with the changes in fair value of the hedged item attributable to the risk being hedged. The expense or (income) recognized in earnings related to fair value hedges was included in interest and other borrowing expenses in the Financial Services segment of the Consolidated Statements of Comprehensive Income as follows:

	Three Months Ended						Nine Months Ended
	September 30						September 30
	2012			2011			2012			2011

Term notes	$	3.2		$	4.9		$	4.7		$	4.2

Cash Flow Hedges

Substantially all of the Company’s interest-rate contracts and some foreign-exchange contracts have been designated as cash flow hedges. Changes in the fair value of derivatives designated as cash flow hedges are recorded in accumulated other comprehensive income to the extent such hedges are considered effective. The maximum length of time over which the Company is hedging its exposure to the variability in future cash flows is 5.7 years.

Amounts in accumulated other comprehensive income are reclassified into net income in the same period in which the hedged transaction affects earnings. Net realized gains and losses from interest-rate contracts are recognized as an adjustment to interest expense. Net realized gains and losses from foreign-exchange contracts are recognized as an adjustment to cost of sales or to Financial Services interest expense, consistent with the hedged transaction. The ineffective portions were a gain of $.2 and a loss of $.1 during the third quarter of 2012 and 2011, respectively, and were gains of $.4 and $.7 during the first nine months of 2012 and 2011, respectively.

The amount of loss recorded in accumulated OCI at September 30, 2012 that is estimated to be reclassified to interest expense or cost of sales in the following 12 months if interest rates and exchange rates remain unchanged is approximately $36.8, net of taxes. The fixed interest earned on finance receivables will offset the amount recognized in interest expense, resulting in a stable interest margin consistent with the Company’s risk management strategy.

Economic Hedges

For other risk management purposes, the Company enters into derivative instruments not designated as hedges that do not qualify for hedge accounting. These derivative instruments are used to mitigate the risk of market volatility arising from borrowings and foreign currency denominated transactions. Changes in the fair value of economic hedges are recorded in earnings in the period in which the change occurs.

The (income) expense recognized in earnings related to economic hedges is as follows:

	Three Months Ended						Nine Months Ended

NOTE J - Fair Value Measurements

Fair value represents the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Inputs to valuation techniques used to measure fair value are either observable or unobservable. These inputs have been categorized into the fair value hierarchy described below.

Level 1 – Valuations are based on inputs from quoted prices that the Company has the ability to obtain in actively traded markets for identical assets or liabilities. Since valuations are based on quoted prices that are readily and regularly available in an active market or exchange traded market, valuation of these instruments does not require a significant degree of judgment.

Level 2 – Valuations are based on inputs from quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.

- 22 -

PACCAR Inc – Form 10-Q

Notes to Consolidated Financial Statements (Unaudited) (Millions, Except Share Amounts)    

Level 3 – Valuations are based on model-based techniques for which some or all of the assumptions are obtained from unobservable market information that is significant to the overall fair value measurement and which require a significant degree of management judgment.

There were no transfers of assets or liabilities between Level 1 and Level 2 of the fair value hierarchy during the nine months ended September 30, 2012. The Company’s policy is to recognize transfers between levels at the end of the reporting period.

The Company uses the following methods and assumptions to measure fair value for assets and liabilities subject to recurring fair value measurements.

Marketable Securities: The Company’s marketable debt securities consist of municipal bonds, government obligations, investment-grade corporate obligations, commercial paper, asset-backed securities and term deposits. The fair value of U.S. government obligations is determined using the market approach and is based on quoted prices in active markets and are categorized as Level 1.

The fair value of non-U.S. government bonds, municipal bonds, corporate bonds, asset-backed securities, commercial paper, and term deposits is determined using the market approach and is primarily based on matrix pricing as a practical expedient which does not rely exclusively on quoted prices for a specific security. Significant inputs used to determine fair value include interest rates, yield curves, credit rating of the security and other observable market information and are categorized as Level 2.

Derivative Financial Instruments: The Company’s derivative contracts consist of interest-rate swaps, cross currency swaps and foreign currency exchange contracts. These derivative contracts are traded over the counter and their fair value is determined using industry standard valuation models, which are based on the income approach (i.e., discounted cash flows). The significant observable inputs into the valuation models include interest rates, yield curves, currency exchange rates, credit default swap spreads and forward spot rates and are categorized as Level 2.

Fair Value Disclosure of Other Financial Instruments

For financial instruments that are not recognized at fair value, the Company uses the following methods and assumptions to determine the fair value. These instruments are categorized as Level 2, except fixed-rate loans which are categorized as Level 3.

Cash and Cash Equivalents: Carrying amounts approximate fair value.

Financial Services Net Receivables: For floating-rate loans, wholesale financings, and accrued rents and other trade receivables, carrying values approximate fair values. For fixed-rate loans, fair values are estimated using the income approach by discounting cash flows to their present value based on current rates for comparable loans. Finance lease receivables and related allowance for credit losses have been excluded from the accompanying table.

Debt: The carrying amounts of financial services commercial paper, variable-rate bank loans and variable-rate term notes approximate fair value. For fixed-rate debt, fair values are estimated using the income approach by discounting cash flows to their present value based on current rates for comparable debt.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW:

PACCAR is a global technology company whose Truck segment includes the design, manufacture and distribution of high-quality, light-, medium- and heavy-duty commercial trucks and related aftermarket parts. In North America, trucks are sold under the Kenworth and Peterbilt nameplates, in Europe, under the DAF nameplate and in Australia and South America, under the Kenworth and DAF nameplates. The Company’s Financial Services segment (PFS) derives its earnings primarily from financing or leasing PACCAR products in the U.S., Canada, Mexico, Europe and Australia. The Company’s other business is the manufacturing and marketing of industrial winches.

Consolidated net sales and revenues in the third quarter of 2012 were $3.82 billion compared to $4.26 billion in the third quarter of 2011. The decrease in the third quarter of 2012 resulted from lower truck unit sales in Europe and the U.S. and Canada, reflecting lower industry truck orders. Third quarter truck unit sales were 31,100 units compared to 35,500 units in the same period in 2011. For the first nine months of 2012, consolidated net sales and revenues were $13.05 billion compared to $11.50 billion for the same period in 2011. For the first nine months of 2012 truck unit sales increased to 108,700 units from 97,100 units in the same period in 2011, primarily due to higher industry retail sales in the U.S. and Canada and record heavy duty truck market share in the U.S. and Canada, and Europe.

Third quarter 2012 net income was $233.6 million ($.66 per diluted share) compared to $281.6 million ($.77 per diluted share) in the third quarter of 2011. The third quarter 2012 results reflect lower sales in the Truck segment compared to the same period in 2011, partially offset by record Financial Services segment results. For the first nine months of 2012, net income was $858.1 million ($2.41 per diluted share) compared to $714.6 million ($1.95 per diluted share) in the first nine months of 2011. The increase in the first nine months of 2012 was primarily due to higher sales in the Truck segment and record Financial Services segment results from higher finance margin and a lower provision for losses on receivables.

The third quarter and first nine months of 2012 consolidated net sales and revenues were negatively affected by the translation of weaker foreign currencies primarily due to the euro. The translation effect decreased net sales and revenues by $122.9 million and $302.6 million for the third quarter of 2012 and the first nine months of 2012, respectively. The effect of weaker foreign currencies on income before income taxes for the third quarter and first nine months of 2012 was not significant.

During September 2012, the Company introduced the new DAF XF Euro 6 truck at the IAA truck show in Hannover, Germany. The new truck is powered by the PACCAR MX-13 Euro 6 engine and is the result of a multi-year design and development program. Production of the new truck will begin in 2013.

Truck Outlook

Industry retail sales in the U.S. and Canada in 2012 are expected to be 210,000-220,000 units compared to 197,000 in 2011. Estimates for U.S. and Canada industry Class 8 retail sales for 2013 are in the range of 210,000-240,000 units, driven primarily by ongoing replacement of the aging fleet. In Europe, 2012 industry sales for over 16-tonne vehicles are expected to be 215,000-225,000 units, lower than the 241,000 trucks in 2011, reflecting economic uncertainty in the Eurozone. Industry sales for over 16-tonne vehicles for 2013 are estimated in the range of 210,000-250,000 units as some customers may purchase Euro 5 vehicles ahead of the introduction of the Euro 6 emission requirement in 2014.

Capital investments in 2012 are expected to be $475 to $525 million. Capital investments in 2013 are expected to be $400 to $500 million, focused on the completion of a truck factory in Brasil and the development of products and services worldwide. Research and development (R&D) in 2012 is expected to be $280 to $290 million and for 2013 to be $275 to $325 million, focused on comprehensive product development programs and enhanced manufacturing operating efficiency.

Financial Services Outlook

Average earning assets in the fourth quarter of 2012 are expected to increase modestly from current levels. For 2013, average earning assets may grow approximately 5-10% as increased new business financing from slightly higher truck sales exceeds portfolio runoff. The Company’s customers are benefiting from the current levels of freight tonnage, freight rates and fleet utilization that are contributing to customers’ profitability and cash flow. If current freight transportation conditions decline due to slowing economic conditions, past-due accounts, truck repossessions and net charge-offs could increase from current low levels.

See the Forward Looking Statement section of Management’s Discussion and Analysis for factors that may affect the Truck and Financial Services outlook.

2012 Compared to 2011:

Truck

The Company’s Truck segment accounted for 92% and 93% of revenues in the third quarter and first nine months of 2012 compared to 93% in both the third quarter and first nine months of 2011.

($ in millions)	Three Months Ended September 30							Nine Months Ended September 30
	2012		2011		% Change			2012		2011		% Change
Truck net sales and revenues:
U.S. and Canada	$	1,820.0	$	2,191.6		(17	)	$	7,017.7	$	5,560.1		26
Europe		930.4		1,185.8		(22	)		2,954.1		3,529.8		(16	)

Truck income before income taxes	$	258.9	$	324.3		(20	)	$	1,022.8	$	855.3		20

The Company’s worldwide truck and parts sales and revenues decreased in the third quarter of 2012 compared to the same period in 2011 due to lower truck deliveries from lower demand in U.S. and Canada, and Europe, partially offset by increased truck demand in Mexico, South America, Australia and other markets. The decrease in Truck segment income before income taxes for the third quarter of 2012 reflects the lower truck deliveries.

In the first nine months of 2012, the Company’s worldwide truck and parts sales and revenues increased compared to the same period in 2011 due to higher market demand in all markets except Europe. The increase in Truck segment income before income taxes for the first nine months of 2012 was due to higher truck unit sales, truck unit margins and aftermarket parts sales, partially offset by an increase in selling, general and administrative (SG&A) expenses to support a higher level of business activity.

The effect of foreign currencies on Truck income before income taxes in the third quarter and first nine months of 2012 was not significant.

The Company’s new truck deliveries are summarized below:

	Three Months Ended September 30							Nine Months Ended September 30
	2012		2011		% Change			2012		2011		% Change
United States		12,200		15,600		(22	)		49,000		40,100		22
Canada		2,100		3,100		(32	)		8,800		7,900		11
U.S. and Canada		14,300		18,700		(24	)		57,800		48,000		20
Europe		10,200		11,800		(14	)		32,200		35,100		(8	)
Mexico, South America, Australia and other		6,600		5,000		32			18,700		14,000		34
Total units		31,100		35,500		(12	)		108,700		97,100		12

The truck markets in the U.S. and Canada, and Europe declined in the third quarter of 2012 compared to 2011 as heightened economic uncertainty has led to reduced demand for new trucks. These lower truck markets were partially offset by stronger truck markets in the third quarter of 2012 compared to 2011 in Mexico, South America, and Australia.

PACCAR Inc – Form 10-Q

In the first nine months of 2012, the U.S. and Canada truck market improved from 2011 from higher freight volumes and the need to replace an aging truck fleet. Industry retail sales in the heavy-duty market in the U.S. and Canada increased to 169,600 units in the first nine months of 2012 compared to 133,900 units in the same period of 2011. The Company’s heavy-duty truck retail market share increased to a record 29.0% in the first nine months of 2012 from 27.7% in the same period of 2011, reflecting higher deliveries to large fleet customers and overall strong demand for the Company’s premium products. The medium-duty market was 48,900 units in the first nine months of 2012 compared to 45,200 units in the same period of 2011. The Company’s medium-duty market share was 14.9% in the first nine months of 2012 compared to 11.4% in the same period of 2011.

The over 16-tonne truck market in Western and Central Europe was 167,900 units in the first nine months of 2012 compared to 180,200 units in the same period of 2011. The Company’s market share was a record 16.0% in the first nine months of 2012, an increase from 15.2% in the same period of 2011. The 6- to 16-tonne market in the first nine months of 2012 was 42,300 units compared to 45,800 units in the same period of 2011. DAF market share in the 6- to 16-tonne market in the first nine months of 2012 was 11.6% compared to 8.4% in the same period of 2011.

Sales and revenues in Mexico, South America, Australia and other markets increased in the third quarter and first nine months of 2012 primarily due to higher new truck deliveries in the Andean region of South America.

The major factors for the change in net sales and revenues, cost of sales and revenues, and gross margin for the three months ended September 30, 2012 are as follows:

($ in millions)	NET SALES			COST OF SALES			GROSS MARGIN
Three Months Ended September 30, 2011	$	3,961.2		$	3,457.6		$	503.6
Increase (decrease)

Three Months Ended September 30, 2012	$	3,510.0		$	3,079.9		$	430.1

• Truck delivery volume reflects lower truck deliveries in the U.S. and Canada, and Europe, partially offset by higher deliveries in Mexico, South America, Australia and other markets. Average truck sales prices increased sales by $23.4 million reflecting increased price realization.

• Average truck cost increased $32.5 million primarily due to higher material costs.

• Factory overhead, warehouse and other indirect costs increased $.3 million primarily due to higher salaries and related costs ($4.0 million), partially offset by lower manufacturing supplies and maintenance ($3.3 million).

• Lower market demand in Europe lowered aftermarket parts volume by $21.2 million and related cost of sales by $11.1 million. This was partially offset by higher market demand in the U.S. and Canada, and Australia that increased aftermarket parts volume by $15.1 million and related cost of sales by $9.6 million.

• Average aftermarket parts sales prices increased by $19.1 million reflecting improved price realization, primarily in North America.

• Average aftermarket parts costs increased $10.9 million from higher material costs.

Nine Months Ended September 30, 2012	$	12,134.7		$	10,569.9		$	1,564.8

• The higher truck delivery volume primarily reflects improved truck markets and market share in North America. The increased demand for trucks also resulted in higher average truck sales prices which increased sales by $247.1 million.

• Average truck cost of sales increased $157.1 million primarily due to higher material costs.

• Factory overhead, warehouse and other indirect costs increased $88.3 million primarily due to higher salaries and related costs ($51.6 million), manufacturing supplies and maintenance ($12.5 million), utilities ($3.1 million) and other overhead costs ($13.1 million) to support higher production levels.

• Higher market demand, primarily in North America, increased aftermarket parts sales volume by $73.1 million and related cost of sales by $49.5 million.

• Average aftermarket parts sales prices increased by $51.6 million reflecting improved price realization.

• Average aftermarket parts costs increased $35.7 million from higher material costs.

• The currency translation effect on sales and cost of sales primarily reflects a decrease in the value of the euro compared to the U.S. dollar.

Total Truck segment gross margins for the third quarter of 2012 were 12.3% compared to 12.7% in the same period in 2011. Total Truck segment gross margins for the first nine months of 2012 and 2011 were 12.9%. The lower truck sales gross margins for the third quarter of 2012 resulted from reduced truck deliveries in the U.S. and Canada, and Europe and decreased absorption of fixed costs resulting from lower truck production. The aftermarket parts gross margins in the third quarter and first nine months of 2012 were comparable to 2011.

Truck R&D expenditures in the third quarter and first nine months of 2012 decreased to $66.7 million and $212.6 million from $69.9 million and $215.5 million in the corresponding periods of 2011, respectively. R&D spending in both periods of 2012 reflects continued focus on product development activities, primarily for new truck models and engine development for North America and Europe. Foreign currency, primarily the euro, reduced R&D in the third quarter and first nine months of 2012 by $5.5 million and $12.4 million, respectively.

Truck SG&A of $104.6 million in the third quarter of 2012 was comparable to $105.6 million in the third quarter of 2011. In the first nine months of 2012, SG&A was $330.6 million and $306.2 million in the first nine months of 2011. The higher spending for the first nine months of 2012 is primarily due to higher salaries and personnel related expenses of $19.0 million to support higher levels of business activity.

As a percentage of sales, SG&A increased to 3.0% in the third quarter of 2012 from 2.7% in the third quarter of 2011, reflecting lower sales volumes. For the first nine months of 2012, SG&A as a percentage of sales was 2.7%, down from 2.9% in the first nine months of 2011 due to higher sales volumes and ongoing cost control. Foreign currency, primarily the euro, reduced SG&A in the third quarter and first nine months of 2012 by $5.2 million and $12.5 million, respectively.

In the third quarter of 2012, new loan and lease volume increased 16% to $1.16 billion compared to the third quarter of 2011. The increase reflects higher finance market share of new PACCAR truck sales and a higher average amount financed per unit, partially offset by lower new PACCAR truck sales. In the third quarter of 2012, PFS market share on new PACCAR trucks increased to 33.1% compared to 29.1% in the same period of 2011 from higher market share in all markets except Mexico. In the first nine months of 2012, new loan and lease volume increased 19% to $3.34 billion compared to the first nine months of 2011. The increase reflects higher new PACCAR truck sales and a higher average amount financed per unit. In the first nine months of 2012, finance market share of 29.8% decreased slightly compared to the 30.2% finance market share in the same period in 2011, primarily due to lower market share in the U.S. and Canada.

The increase in PFS revenues primarily resulted from higher average earning asset balances, partially offset by lower yields. PFS income before income taxes increased to $80.4 million and $229.1 million in the third quarter and first nine months of 2012 compared to $61.8 million and $169.0 million in the same periods in 2011 primarily due to higher finance margins and a lower provision for losses as noted below.

The Company modifies loans and finance leases as a normal part of its Financial Services operations. The Company may modify loans and finance leases for commercial reasons or for credit reasons. Modifications for commercial reasons are changes to contract terms for customers that are not considered to be in financial difficulty. Insignificant delays are modifications extending terms up to three months for customers experiencing some short term financial stress but not considered to be in financial difficulty. Modifications for credit reasons are changes to contract terms for customers considered to be in financial difficulty. The Company’s modifications typically result in granting more time to pay the contractual amounts owed and charging a fee and interest for the term of the modification. When considering whether to modify customer accounts for credit reasons, the Company evaluates the creditworthiness of the customers and modifies those accounts that the Company considers likely to perform under the modified terms. When the Company modifies loans and finance leases for credit reasons and grants a concession, the modifications are classified as troubled debt restructurings.

The accounts modified during the nine months ended September 30, 2012 and 2011 are summarized below:

	Nine Months Ended
	September 30, 2012					September 30, 2011
	Recorded Investment		% of Total Portfolio*			Recorded Investment		% of Total Portfolio*
Commercial	$	168.0		2.7	%	$	152.9		3.0	%

Credit - Troubled Debt Restructuring		45.9		.8	%		29.5		.6	%
	$	291.2		4.8	%	$	337.6		6.7	%

*  Recorded investment at time of modification as a percentage of ending portfolio, on an annualized basis.

Total modification activity decreased in 2012 compared to 2011 due to lower insignificant delay modifications in Australia. In the first quarter of 2011 due to severe flooding in the Queensland, Australia region, the Company provided modifications to credit qualified customers. In addition, the Company’s TDR modifications increased in 2012 from 2011 due to one large customer account in Europe and one in the U.S. These were partially offset by higher commercial modifications reflecting growth in the portfolio.

The following table summarizes the Company’s 30+ days past-due accounts:

	September 30 2012			December 31 2011			September 30 2011
Percentage of retail loan and lease accounts 30+ days past due:
U.S. and Canada		.7	%		1.1	%		1.3	%
Europe		1.0	%		1.0	%		1.4	%
Mexico and Australia		1.8	%		3.4	%		5.3	%
Worldwide		.9	%		1.5	%		2.1	%

Worldwide PFS accounts 30+ days past due were .9% at September 30, 2012 and have improved from 1.5% at December 31, 2011 and 2.1% at September 30, 2011. The U.S. and Canada past-due percentage of .7% includes .5% from one customer. Excluding that customer, worldwide PFS accounts 30+ days past due at September 30, 2012 would have been .6%. At September 30, 2012, the Company had $21.5 million of specific loss reserves for this customer and other accounts considered at risk. The Company continues to focus on maintaining low past-due balances.

PACCAR Inc – Form 10-Q

When the Company modifies a 30+ days past-due account, the customer is then generally considered current under the revised contractual terms. The Company modified $10.5 million of accounts worldwide during the third quarter of 2012, $4.5 million during the fourth quarter of 2011 and $8.0 million during the third quarter of 2011 that were 30+ days past-due and became current at the time of modification. Of these modifications, $9.9 million during the third quarter of 2012, $4.4 million during the fourth quarter of 2011 and $6.4 million during the third quarter of 2011 were in Mexico and Australia. Had these accounts not been modified and continued to not make payments, the pro forma percentage of retail loan and lease accounts 30+ days past due would have been as follows:

	September 30 2012			December 31 2011			September 30 2011
Pro forma percentage of retail loan and lease accounts 30+ days past due:
U.S. and Canada		.7	%		1.1	%		1.4	%
Europe		1.0	%		1.0	%		1.4	%
Mexico and Australia		2.8	%		3.8	%		6.0	%
Worldwide		1.1	%		1.5	%		2.2	%

Modifications of accounts in prior quarters that were more than 30 days past due at the time of modification are included in past-dues if they were not performing under the modified terms at September 30, 2012, December 31, 2011 and September 30, 2011. The effect on the allowance for credit losses from such modifications was not significant at September 30, 2012, December 31, 2011 and September 30, 2011.

For the third quarter of 2012, the Company’s pretax return on revenue for Financial Services increased to 29.4% from 23.4% in the third quarter of 2011. For the first nine months of 2012, the Company’s pretax return on revenue for Financial Services increased to 28.6% from 22.1% in the first nine months of 2011. The higher pretax returns in 2012 were primarily due to higher finance margin from a lower cost of funds as well as a lower provision for losses on receivables from improved portfolio quality.

Other

Other includes the winch business as well as sales, income and expenses not attributable to a reportable segment, including a portion of corporate expense. Other sales represent approximately 1% of consolidated net sales and revenues for the third quarter and first nine months of 2012 and 2011. Other SG&A was $9.4 million and $31.6 million in the third quarter and first nine months of 2012 compared to $7.6 million and $25.4 million in the third quarter and first nine months of 2011, respectively. Other SG&A increased due to higher salary related expenses. Other income (loss) before tax was a loss of $1.7 million and $6.1 million in the third quarter and first nine months of 2012 compared to a loss of $2.4 million and $19.0 million in the same periods of 2011, primarily due to improved winch business results and lower equipment expenses.

Investment income was $7.8 million and $24.9 million in the third quarter and first nine months of 2012 compared to $11.0 million and $28.9 million in the same periods of 2011, respectively. The lower investment income in the third quarter and first nine months of 2012 primarily reflects lower market interest rates.

The effective income tax rate in the third quarter of 2012 was 32.4% an increase from 28.7% in the third quarter of 2011 due to a lower mix of foreign income in jurisdictions with lower tax rates. For the first nine months of 2012, the effective income tax rate was 32.5% an increase from 30.9% in the first nine months of 2011. The higher tax rate in the first nine months of 2012 primarily reflects an increased proportion of domestic income.

For the third quarter of 2012, the decrease in income before income taxes for domestic and foreign operations compared to the third quarter of 2011 was primarily due to Truck operations. The third quarter of 2012 return on revenues for domestic operations of 7.9% declined from 8.1% in 2011 and the third quarter of 2012 return on revenues for foreign operations of 10.0% declined from 10.3% in 2011. Both results reflect lower returns on Truck operations, partially offset by higher returns for Financial Services operations.

For the first nine months of 2012, the increase in income before taxes for domestic operations and the decrease in income before taxes for foreign operations compared to the first nine months of 2011 were primarily due to Truck operations. The decrease in foreign income before taxes for Truck operations was due to lower truck sales in Europe partially offset by higher sales in Latin America and Australia. The 2012 higher return on revenues for domestic operations of 9.4% compared to 6.7% in 2011 resulted from higher returns for both Truck and Financial Services operations. The 2012 lower return on revenues in foreign operations of 10.1% compared to 10.8% in 2011 resulted from lower returns on Truck operations partially offset by higher returns on Financial Services operations.

Operating activities: Cash provided by operations decreased $234.7 million to $916.6 million in the first nine months of 2012. The lower operating cash flow was primarily due to a $649.5 million lower increase in purchases of goods and services in accounts payable and accrued expenses greater than payments compared to the first nine months of 2011 as well as a $170.2 million outflow from income tax payments exceeding expense in 2012 and income tax expense exceeding payments in 2011. In addition, lower operating cash flow resulted from a larger increase in Financial Services segment sales-type finance lease and dealer direct loan originations than payments of $93.5 million as well as higher pension contributions of $80.8 million. These were partially offset by $391.5 million from a lower increase in sales of goods and services in accounts receivable greater than receipts compared to the first nine months of 2011, a $251.5 million lower increase in Financial Services segment wholesale receivables and $143.5 million of higher net income.

Investing activities: Cash used in investing activities of $1.66 billion in the first nine months of 2012 decreased $123.1 million from the $1.79 billion used in the first nine months of 2011. In the first nine months of 2012, lower net purchases of marketable securities of $420.4 million were made compared to the first nine months of 2011. The lower net purchases of marketable debt securities in the first nine months of 2012 was partially offset by $256.5 million of higher net new loan and lease originations in the Financial Services segment reflecting increased portfolio growth.

Financing activities: Cash provided by financing activities in the first nine months of 2012 of $380.0 million was $132.3 million lower than the cash provided by financing activities in the first nine months of 2011. In the first nine months of 2012 the Company paid $455.9 million of dividends, an increase of $302.8 million compared to $153.1 million paid in the first nine months ended 2011. The higher amounts paid results from a special dividend declared in 2011 and paid in 2012 and a higher regular quarterly dividend rate in 2012. Treasury stock purchases of $162.1 million were $88.1 million lower than 2011. The Company issued $1.95 billion of long term debt, $885.6 million higher than 2011. The proceeds were partially used to repay medium term debt of $402.6 million and to reduce outstanding balances of commercial paper by $557.9 million resulting in an increase in cash provided by net borrowings of $990.6 million compared to $911.2 million in 2011. In both periods cash provided by net borrowings was used to fund growth in the Financial Services portfolios.

Credit Lines and Other

The Company has line of credit arrangements of $3.69 billion, of which $3.44 billion were unused at September 30, 2012. Included in these arrangements are $3.0 billion of syndicated bank facilities, of which $1.0 billion matures in June 2013, $1.0 billion matures in June 2016 and $1.0 billion matures in June 2017. The Company intends to replace these credit facilities as they expire with facilities of similar amounts and duration. These credit facilities are maintained primarily to provide backup liquidity for commercial paper borrowings and maturing medium-term notes. There were no borrowings under the syndicated bank facilities for the nine months ended September 30, 2012.

PACCAR Inc – Form 10-Q

In December 2011, PACCAR Inc filed a shelf registration under the Securities Act of 1933. The current registration expires in the fourth quarter of 2014 and does not limit the principal amount of debt securities that may be issued during the period. The total amount of medium-term notes outstanding for PACCAR Inc as of September 30, 2012 was $500.0 million.

In December 2011, PACCAR’s Board of Directors approved the repurchase of an additional $300.0 million of the Company’s common stock and as of September 30, 2012, $192.0 million of shares have been repurchased pursuant to the authorization.

Truck and Other

The Company provides funding for working capital, capital expenditures, R&D, dividends, stock repurchases and other business initiatives and commitments primarily from cash provided by operations. Management expects this method of funding to continue in the future. Long-term debt totaled $150.0 million as of September 30, 2012.

Expenditures for property, plant and equipment in the first nine months of 2012 totaled $333.7 million compared to $211.1 million in the first nine months of 2011 as the Company invested in tooling and factory equipment for new products. Capital spending in 2012 is expected to be approximately $475 to $525 million. The capital spending primarily relates to comprehensive product development programs and geographic expansion, including building a new DAF factory in Brasil. Spending on R&D in 2012 is expected to be $280 to $290 million. PACCAR continues to focus on new product programs, engine development and manufacturing efficiency improvements.

The Company conducts business in the countries of Spain, Italy, Portugal, Ireland and Greece, which have been experiencing significant financial stress. As of September 30, 2012, the Company had finance and trade receivables in these countries of approximately 1% of consolidated total assets. As of September 30, 2012, the Company did not have any marketable debt security investments in corporate or sovereign government securities in these countries. In addition, the Company had no derivative counterparty credit exposures in these countries as of September 30, 2012.

Financial Services

The Company funds its financial services activities primarily from collections on existing finance receivables and borrowings in the capital markets. An additional source of funds is loans from other PACCAR companies.

The primary sources of borrowings in the capital markets are commercial paper and medium-term notes issued in the public markets and, to a lesser extent, bank loans.

The Company issues commercial paper for a portion of its funding in its Financial Services segment. Some of this commercial paper is converted to fixed interest rate debt through the use of interest rate swaps, which are used to manage interest rate risk. In the event of future disruption in the financial markets, the Company may not be able to issue replacement commercial paper. As a result, the Company is exposed to liquidity risk from the shorter maturity of short-term borrowings paid to lenders compared to the longer timing of receivable collections from customers. The Company believes its cash balances and investments, syndicated bank lines and current investment-grade credit ratings of A+/A1 will continue to provide it with sufficient resources and access to capital markets at competitive interest rates and therefore contribute to the Company maintaining its liquidity and financial stability. A decrease in these credit ratings could negatively impact the Company’s ability to access capital markets at competitive interest rates and the Company’s ability to maintain liquidity and financial stability.

In November 2009, the Company’s U.S. finance subsidiary, PACCAR Financial Corp. (PFC), filed a shelf registration statement under the Securities Act of 1933 effective for a three year period. The total amount of medium-term notes outstanding for PFC as of September 30, 2012 was $2.70 billion. PFC intends to file a new registration statement in November 2012.

PACCAR Inc – Form 10-Q

As of September 30, 2012, the Company’s European finance subsidiary, PACCAR Financial Europe, had €717.3 million available for issuance under a €1.50 billion medium-term note program registered with the London Stock Exchange. The program was renewed in the second quarter of 2012 and is renewable annually through the filing of a new prospectus.

In April 2011, PACCAR Financial Mexico registered a 10.00 billion peso medium-term note and commercial paper program with the Comision Nacional Bancaria y de Valores. The registration expires in 2016 and limits the amount of commercial paper (up to one year) to 5.00 billion pesos. At September 30, 2012, 8.06 billion pesos remained available for issuance.

PACCAR believes its Financial Services companies will be able to continue funding receivables, servicing debt and paying dividends through internally generated funds, access to public and private debt markets and lines of credit.

PART II – OTHER INFORMATION

For Items 3, 4 and 5, there was no reportable information for the nine months ended September 30, 2012.

ITEM 1. LEGAL PROCEEDINGS

The Company and its subsidiaries are parties to various lawsuits incidental to the ordinary course of business. Management believes that the disposition of such lawsuits will not materially affect the Company’s business or financial condition.

The Company received notice on April 24, 2012 that the Securities and Exchange Commission (“SEC”) had initiated a formal investigation relating to the Company’s financial reporting from 2008 to 2011. The SEC has requested information concerning the Company’s loan loss reserves, troubled debt restructuring and segment reporting. The Company is cooperating fully with the SEC’s investigation.

On July 15, 2011, the National Labor Relations Board (“NLRB”) ruled unanimously that the Company is not required to compensate former employees of the Peterbilt plant in Madison, Tennessee for wages and benefits incurred during a work stoppage that ended on April 9, 2009. On December 20, 2011 the NLRB denied a motion to reconsider its decision filed by the union that represented the plant production employees. On April 17, 2012, the union filed a petition for review of the July 15, 2011 NLRB decision in the U.S. Court of Appeals for the Sixth Circuit. The Company believes the likelihood of an outcome adverse to the Company is remote.

In September 2010, the United Kingdom Office of Fair Trading (OFT) notified commercial vehicle manufacturers operating in the U.K., including two of the Company’s subsidiaries, that it had commenced an investigation into whether such manufacturers agreed to set prices or limit supply of their products. On June 15, 2012 the OFT announced it had closed its investigation. The OFT stated that the European Commission was well placed to take the investigation forward as part of its investigation into the European truck industry.

ITEM 1A. RISK FACTORS

For information regarding risk factors, refer to Part I, Item 1A as presented in the 2011 Annual Report on Form 10-K. There have been no material changes in the Company’s risk factors during the nine months ended September 30, 2012.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

For items 2(a) and (b), there was no reportable information for the nine months ended September 30, 2012.

Accrued rents and other trade receivables		(6.1	)		(8.8	)
	$	8,133.0		$	7,259.7

Recognition of interest income and rental revenue is suspended (put on non-accrual status) when the receivable becomes more than 90 days past the contractual due date or earlier if some other event causes the Company to determine that collection is not probable. Accordingly, there were no finance receivables more than 90 days past due still accruing interest at September 30, 2012 or December 31, 2011. Recognition is resumed if the receivable becomes current by the payment of all amounts due under the terms of the existing contract and collection of remaining amounts is considered probable (if not contractually modified), or after the customer has made scheduled payments for three months and collection of remaining amounts is considered probable (if contractually modified). Payments received while the finance receivable is impaired or on non-accrual status are applied to interest and principal in accordance with the contractual terms.

Allowance for Credit Losses

The Company continuously monitors the payment performance of all its finance receivables. For large retail finance customers and dealers with wholesale financing, the Company regularly reviews their financial statements and makes site visits and phone contact as appropriate. If the Company becomes aware of circumstances that could cause those customers or dealers to face financial difficulty, whether or not they are past due, the customers are placed on a watch list.

The Company modifies loans and finance leases as a normal part of its Financial Services operations. The Company may modify loans and finance leases for commercial reasons or for credit reasons. Modifications for commercial reasons are changes to contract terms for customers that are not considered to be in financial difficulty. Modifications for credit reasons are changes to contract terms for customers considered to be in financial difficulty. The Company’s modifications typically result in granting more time to pay the contractual amounts owed and charging a fee and interest for the term of the modification.

When considering whether to modify customer accounts for credit reasons, the Company evaluates the creditworthiness of the customers and modifies those accounts that the Company considers likely to perform under the modified terms. When the Company modifies loans and finance leases for credit reasons and grants a concession, the modifications are classified as troubled debt restructurings (TDRs). The Company does not typically grant credit modifications for customers that do not meet minimum underwriting standards since the Company normally repossesses the financed equipment in these circumstances. When such modifications do occur, they are considered TDRs.

On average, modifications extended contractual terms by approximately eight months in 2012 and nine months in 2011 and did not have a significant effect on the weighted average term or interest rate of the total portfolio at September 30, 2012 and December 31, 2011.

The Company has developed a systematic methodology for determining the allowance for credit losses for its two portfolio segments, retail and wholesale. The retail segment consists of retail loans and direct and sales-type finance leases, net of unearned interest. The wholesale segment consists of wholesale financing loans to dealers that are collateralized by trucks and other collateral. The wholesale segment generally has less risk than the retail segment. Wholesale receivables generally are shorter in duration than retail receivables, and the Company requires monthly reporting of the wholesale dealer’s financial condition, conducts periodic audits of the trucks being financed and in many cases, obtains personal guarantees or other security such as dealership assets. In determining the allowance for credit losses, retail loans and finance leases are evaluated together since they relate to a similar customer base, their contractual terms require regular payment of principal and interest generally over 36 to 60 months and they are secured by the same type of collateral. The allowance for credit losses consists of both specific and general reserves.

The Company individually evaluates certain finance receivables for impairment. Finance receivables which are evaluated individually for impairment consist of all wholesale accounts and certain large retail accounts with past due balances or otherwise determined to be at a higher risk of loss. A finance receivable is impaired if it is considered probable the Company will be unable to collect all contractual interest and principal payments as scheduled. In addition, all retail loans and leases which have been classified as TDRs and all customer accounts over 90 days past due are considered impaired. All impaired accounts are on non-accrual status.

Impaired receivables are considered collateral dependent. Large balance retail and all wholesale impaired receivables are individually evaluated to determine the appropriate reserve for losses. The determination of reserves for large balance impaired receivables considers the fair value of the associated collateral. When the underlying collateral fair value exceeds the Company’s loss exposure, no reserve is recorded. Small balance impaired receivables with similar risk characteristics are evaluated as a separate pool to determine the appropriate reserve for losses using the historical loss information discussed below.

For finance receivables that are not individually impaired, the Company collectively evaluates and determines the general allowance for credit losses for both retail and wholesale receivables based on historical loss information, using past-due account data and current market conditions. Information used includes assumptions regarding the likelihood of collecting current and past-due accounts, repossession rates, the recovery rate on the underlying collateral based on used truck values and other pledged collateral or recourse. The Company has developed a range of loss estimates for each of its country portfolios based on historical experience, taking into account loss frequency and severity in both strong and weak truck market conditions. A projection is made of the range of estimated credit losses inherent in the portfolio from which an amount is determined as probable based on current market conditions and other factors impacting the creditworthiness of the Company’s borrowers and their ability to repay. After determining the appropriate level of the allowance for credit losses, the provision for losses on finance receivables is charged to income as necessary to reflect management’s estimate of incurred credit losses, net of recoveries, inherent in the portfolio.

In determining the fair value of the collateral, the Company uses a pricing model and categorizes the fair value as Level 2 in the hierarchy of fair value measurement. The pricing model is reviewed quarterly and updated as appropriate. The pricing model considers the make, model and year of the equipment as well as recent sales prices of comparable equipment through wholesale channels to the Company’s dealers (principal market). The fair value of the collateral also considers the overall condition of the equipment.

Accounts are charged-off against the allowance for credit losses when, in the judgment of management, they are considered uncollectable (generally upon repossession of the collateral). Typically the timing between the repossession and charge-off is not significant. In cases where repossession is delayed (e.g., for legal proceedings), the Company records partial charge-offs. The charge-off is determined by comparing the fair value of the collateral, less cost to sell, to the recorded investment.

The allowance for credit losses is summarized as follows:

The recorded investment for finance receivables that are on non-accrual status in the wholesale segment and the fleet and owner/operator portfolio classes (as defined in impaired loans below) as of September 30, 2012 was $2.9, $57.4 and $12.8, respectively, and as of December 31, 2011 was $18.4, $63.9 and $17.6, respectively.

Impaired Loans

The Company’s impaired loans are segregated by portfolio class. A portfolio class of receivables is a subdivision of a portfolio segment with similar measurement attributes and risk characteristics and common methods to monitor and assess credit risk. The Company’s retail segment is subdivided into the fleet and owner/operator classes. Fleet consists of retail accounts with customers operating more than five trucks. All others are owner/operator.

Substantially all impaired loans have a specific reserve and are summarized below. The impaired loans with specific reserve represent the unpaid principal loan balance.

Credit Quality

The Company’s customers are principally concentrated in the transportation industry in North America, Europe and Australia. On a geographic basis, there is a proportionate concentration of credit risk in each area. The Company retains as collateral a security interest in the related equipment.

At the inception of each contract, the Company considers the credit risk based on a variety of credit quality factors including; prior payment experience, customer financial information, credit-rating agency ratings, loan-to-value ratios and other internal metrics. On an ongoing basis, the Company monitors credit quality based on past-due status and collection experience as the Company has found a meaningful correlation between the past due status of customers and the risk of loss.

The Company has three credit quality indicators: performing, watch and at-risk. Performing accounts pay in accordance with the contractual terms and are not considered high risk. Watch accounts include accounts 31 to 90 days past due and large accounts that are performing but are considered to be high-risk. Watch accounts are not impaired. At-risk accounts are accounts that are impaired, including TDRs, accounts over 90 days past-due and other accounts on non-accrual status. The Company uses historical data and known trends to estimate default rates for each credit quality indicator. The tables below summarize the Company’s finance receivables by credit quality indicator and portfolio class.

At September 30, 2012	WHOLESALE		FLEET		OWNER / OPERATOR		TOTAL

The tables below summarize the Company’s finance receivables by aging category. In determining past due status, the Company considers the entire contractual account balance past due when any installment is over 30 days past due. Substantially all customer accounts that were greater than 30 days past due prior to credit modification became current upon modification for aging purposes.

Troubled Debt Restructurings

For the three and nine months ended September 30, 2012, the decrease in the recorded investment for loans and leases modified as TDRs was $.8 and $1.5, respectively, resulting in post-modification recorded investment of $14.5 and $45.9, respectively. At modification date, the pre-modification and post-modification recorded investment balances by portfolio class are as follows:

	Three Months Ended				Nine Months Ended
	September 30, 2012				September 30, 2012
	Recorded Investment				Recorded Investment
	Pre- Modification		Post- Modification		Pre- Modification		Post- Modification
Fleet	$	14.7	$	13.9	$	45.3	$	43.8
Owner / Operator		.6		.6		2.1		2.1
	$	15.3	$	14.5	$	47.4	$	45.9

Owner / Operator		.7		.7		5.2		5.2
	$	4.1	$	4.1	$	29.7	$	29.5

The balance of TDRs was $44.0 at September 30, 2012 and $26.0 at December 31, 2011.

The recorded investment in finance receivables modified as TDRs during the previous twelve months that subsequently defaulted (i.e., became more than 30 days past-due) in the nine months ended September 30, 2012 was $7.7 and $.5 for fleet and owner/operator, respectively. Included in the $7.7 of fleet redefaults is $4.8 from one customer, for which the Company had a specific reserve of $1.8 as of September 30, 2012. The TDRs that subsequently defaulted did not significantly impact the Company’s allowance for credit losses at September 30, 2012.

Repossessions

When the Company determines that a past-due customer is not likely to meet its contractual commitments, the Company repossesses the vehicles which serve as collateral for loans, finance leases and equipment under operating lease. The Company records the repossessed vehicles as used truck inventory which is included in Financial Services other assets on the Consolidated Balance Sheets. The balance of repossessed inventory at September 30, 2012 and December 31, 2011 was $10.8 and $16.0, respectively. Proceeds from the sales of repossessed assets were $48.7 and $65.7 for the nine months ended September 30, 2012 and 2011, respectively. These amounts are included in proceeds from asset disposals on the Condensed Consolidated Statements of Cash Flows. Write-downs of repossessed equipment on operating leases are recorded as impairments and included in Financial Services depreciation and other expense on the Consolidated Statements of Comprehensive Income.

Inventories

NOTE C - Inventories

Inventories are stated at the lower of cost or market. Cost of inventories in the U.S. is determined principally by the last-in, first-out (LIFO) method. Cost of all other inventories is determined principally by the first-in, first-out (FIFO) method.

Inventories include the following:

	September 30 2012			December 31 2011
Finished products	$	486.3		$	436.2
Work in process and raw materials		597.6			439.6
		1,083.9			875.8
Less LIFO reserve		(168.3	)		(165.4	)
	$	915.6		$	710.4

Under the LIFO method of accounting (used for approximately 47% of September 30, 2012 inventories), an actual valuation can be made only at the end of each year based on year-end inventory levels and costs. Accordingly, interim valuations are based on management’s estimates of those year-end amounts.

Basis of Presentation

NOTE A - Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2012 are not necessarily indicative of the results that may be expected for the year ending December 31, 2012. For further information, refer to the consolidated financial statements and footnotes included in PACCAR Inc’s (the Company) Annual Report on Form 10-K for the year ended December 31, 2011.

Earnings per Share: Basic earnings per common share are computed by dividing earnings by the weighted average number of common shares outstanding, plus the effect of any participating securities. Diluted earnings per common share are computed assuming that all potentially dilutive securities are converted into common shares under the treasury stock method. The dilutive and antidilutive options are shown separately in the table below.

New Accounting Pronouncements: In May 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs. While many of the amendments are clarifications to the existing guidance and are intended to align U.S. GAAP and International Financial Reporting Standards (IFRS), the ASU changes some fair value measurement principles and disclosure requirements. The Company adopted ASU 2011-04 in the first quarter of 2012; the implementation of this amendment resulted in additional disclosures (see note J), but did not have a significant impact on the Company’s consolidated financial statements.

The FASB issued ASU 2011-05, Presentation of Comprehensive Income, in June 2011, which was subsequently amended by ASU 2011-12 in December 2011. The new guidance requires entities to present components of net income and comprehensive income in either a combined financial statement or in two separate but consecutive statements of net income and comprehensive income. The Company adopted ASU 2011-05 as amended in the first quarter of 2012 and has elected to present components of net income combined with a total for comprehensive income in a single continuous statement in its consolidated interim financial statements. The Company is currently evaluating which method to adopt in the consolidated annual financial statements.

Investments in Marketable Debt Securities

Sep. 30, 2012

Investments in Marketable Debt Securities

NOTE B - Investments in Marketable Debt Securities

The Company’s investments in marketable debt securities are classified as available-for-sale. These investments are stated at fair value with any unrealized gains or losses, net of tax, included as a component of accumulated other comprehensive income (loss).

The Company utilizes third-party pricing services for all of its marketable debt security valuations. The Company reviews the pricing methodology used by the third-party pricing services including the manner employed to collect market information. On a periodic basis, the Company also performs review and validation procedures on the pricing information received from the third-party providers. These procedures help ensure that the fair value information used by the Company is determined in accordance with applicable accounting guidance.

The Company evaluates its investment in marketable debt securities at the end of each reporting period to determine if a decline in fair value is other than temporary. Realized losses are recognized upon management’s determination that a decline in fair value is other than temporary. The determination of other-than-temporary impairment is a subjective process, requiring the use of judgments and assumptions regarding the amount and timing of recovery. The Company reviews and evaluates its investments at least quarterly to identify investments that have indications of other-than-temporary impairments. It is reasonably possible that a change in estimate could occur in the near term relating to other-than-temporary impairment. Accordingly, the Company considers several factors when evaluating debt securities for other-than-temporary impairment, including whether the decline in fair value of the security is due to increased default risk for the specific issuer or market interest rate risk.

In assessing default risk, the Company considers the collectability of principal and interest payments by monitoring changes to issuers’ credit ratings, specific credit events associated with individual issuers as well as the credit ratings of any financial guarantor, and the extent and duration to which amortized cost exceeds fair value.

In assessing market interest rate risk, including benchmark interest rates and credit spreads, the Company considers its intent for selling the securities and whether it is more likely than not the Company will be able to hold these securities until the recovery of any unrealized losses.

Marketable debt securities at September 30, 2012 and December 31, 2011 consisted of the following:

At September 30, 2012	AMORTIZED COST		UNREALIZED GAINS		UNREALIZED LOSSES		FAIR VALUE
U.S. tax-exempt securities	$	299.7	$	2.6			$	302.3
U.S. corporate securities		27.9		.3				28.2
U.S. government and agency securities		1.2						1.2
Non-U.S. government securities		386.1		7.4				393.5
Non-U.S. corporate securities		150.3		1.1				151.4
Other debt securities		78.6		.7				79.3
	$	943.8	$	12.1			$	955.9
At December 31, 2011	AMORTIZED COST		UNREALIZED GAINS		UNREALIZED LOSSES		FAIR VALUE
U.S. tax-exempt securities	$	291.9	$	2.6	$	.1	$	294.4
U.S. corporate securities		27.4		.3		.2		27.5
U.S. government and agency securities		1.9						1.9
Non-U.S. government securities		361.2		6.0		.1		367.1
Non-U.S. corporate securities		148.0		.5		.2		148.3
Other debt securities		70.3		.6				70.9
	$	900.7	$	10.0	$	.6	$	910.1

The cost of marketable debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Amortization, accretion, interest and dividend income and realized gains and losses are included in investment income. The cost of securities sold is based on the specific identification method. The proceeds from sales and maturities of marketable securities for the nine months ended September 30, 2012 were $445.8. Gross realized gains were $1.9 and $2.2 and gross realized losses were $.1 and $.6 for the nine months ended September 30, 2012 and 2011, respectively.

The fair value of marketable debt securities that have been in an unrealized loss position for 12 months or greater at September 30, 2012 was $2.6 and the associated unrealized loss was $.01. At September 30, 2011, there were no marketable debt securities in an unrealized loss position for greater than 12 months.

For the investment securities in gross unrealized loss positions identified above, the Company does not intend to sell the investment securities, it is more likely than not that the Company will not be required to sell the investment securities before recovery of the unrealized losses, and the Company expects that the contractual principal and interest will be received on the investment securities. As a result, the Company recognized no other-than-temporary impairments during the periods presented.

Contractual maturities on marketable debt securities at September 30, 2012 were as follows:

Maturities:	AMORTIZED COST		FAIR VALUE
Within one year	$	326.6	$	328.3
One to five years		615.7		626.1
Six to ten years		.2		.2
More than ten years		1.3		1.3
	$	943.8	$	955.9

Marketable debt securities included $1.3 and $7.1 of variable rate demand obligations (VRDOs) at September 30, 2012 and December 31, 2011, respectively. VRDOs are debt instruments with long-term scheduled maturities which have interest rates that reset periodically.

Finance and Other Receivables (Policies)

Allowance for Credit Losses

Allowance for Credit Losses

The Company continuously monitors the payment performance of all its finance receivables. For large retail finance customers and dealers with wholesale financing, the Company regularly reviews their financial statements and makes site visits and phone contact as appropriate. If the Company becomes aware of circumstances that could cause those customers or dealers to face financial difficulty, whether or not they are past due, the customers are placed on a watch list.

The Company modifies loans and finance leases as a normal part of its Financial Services operations. The Company may modify loans and finance leases for commercial reasons or for credit reasons. Modifications for commercial reasons are changes to contract terms for customers that are not considered to be in financial difficulty. Modifications for credit reasons are changes to contract terms for customers considered to be in financial difficulty. The Company’s modifications typically result in granting more time to pay the contractual amounts owed and charging a fee and interest for the term of the modification.

When considering whether to modify customer accounts for credit reasons, the Company evaluates the creditworthiness of the customers and modifies those accounts that the Company considers likely to perform under the modified terms. When the Company modifies loans and finance leases for credit reasons and grants a concession, the modifications are classified as troubled debt restructurings (TDRs). The Company does not typically grant credit modifications for customers that do not meet minimum underwriting standards since the Company normally repossesses the financed equipment in these circumstances. When such modifications do occur, they are considered TDRs.

On average, modifications extended contractual terms by approximately eight months in 2012 and nine months in 2011 and did not have a significant effect on the weighted average term or interest rate of the total portfolio at September 30, 2012 and December 31, 2011.

The Company has developed a systematic methodology for determining the allowance for credit losses for its two portfolio segments, retail and wholesale. The retail segment consists of retail loans and direct and sales-type finance leases, net of unearned interest. The wholesale segment consists of wholesale financing loans to dealers that are collateralized by trucks and other collateral. The wholesale segment generally has less risk than the retail segment. Wholesale receivables generally are shorter in duration than retail receivables, and the Company requires monthly reporting of the wholesale dealer’s financial condition, conducts periodic audits of the trucks being financed and in many cases, obtains personal guarantees or other security such as dealership assets. In determining the allowance for credit losses, retail loans and finance leases are evaluated together since they relate to a similar customer base, their contractual terms require regular payment of principal and interest generally over 36 to 60 months and they are secured by the same type of collateral. The allowance for credit losses consists of both specific and general reserves.

The Company individually evaluates certain finance receivables for impairment. Finance receivables which are evaluated individually for impairment consist of all wholesale accounts and certain large retail accounts with past due balances or otherwise determined to be at a higher risk of loss. A finance receivable is impaired if it is considered probable the Company will be unable to collect all contractual interest and principal payments as scheduled. In addition, all retail loans and leases which have been classified as TDRs and all customer accounts over 90 days past due are considered impaired. All impaired accounts are on non-accrual status.

Impaired receivables are considered collateral dependent. Large balance retail and all wholesale impaired receivables are individually evaluated to determine the appropriate reserve for losses. The determination of reserves for large balance impaired receivables considers the fair value of the associated collateral. When the underlying collateral fair value exceeds the Company’s loss exposure, no reserve is recorded. Small balance impaired receivables with similar risk characteristics are evaluated as a separate pool to determine the appropriate reserve for losses using the historical loss information discussed below.

For finance receivables that are not individually impaired, the Company collectively evaluates and determines the general allowance for credit losses for both retail and wholesale receivables based on historical loss information, using past-due account data and current market conditions. Information used includes assumptions regarding the likelihood of collecting current and past-due accounts, repossession rates, the recovery rate on the underlying collateral based on used truck values and other pledged collateral or recourse. The Company has developed a range of loss estimates for each of its country portfolios based on historical experience, taking into account loss frequency and severity in both strong and weak truck market conditions. A projection is made of the range of estimated credit losses inherent in the portfolio from which an amount is determined as probable based on current market conditions and other factors impacting the creditworthiness of the Company’s borrowers and their ability to repay. After determining the appropriate level of the allowance for credit losses, the provision for losses on finance receivables is charged to income as necessary to reflect management’s estimate of incurred credit losses, net of recoveries, inherent in the portfolio.

In determining the fair value of the collateral, the Company uses a pricing model and categorizes the fair value as Level 2 in the hierarchy of fair value measurement. The pricing model is reviewed quarterly and updated as appropriate. The pricing model considers the make, model and year of the equipment as well as recent sales prices of comparable equipment through wholesale channels to the Company’s dealers (principal market). The fair value of the collateral also considers the overall condition of the equipment.

Accounts are charged-off against the allowance for credit losses when, in the judgment of management, they are considered uncollectable (generally upon repossession of the collateral). Typically the timing between the repossession and charge-off is not significant. In cases where repossession is delayed (e.g., for legal proceedings), the Company records partial charge-offs. The charge-off is determined by comparing the fair value of the collateral, less cost to sell, to the recorded investment.

Income Taxes

NOTE G - Income Taxes

The effective income tax rate in the third quarter of 2012 was 32.4% an increase from 28.7% in the third quarter of 2011 due to a higher mix of foreign income in jurisdictions with higher tax rates. For the first nine months of 2012, the effective income tax rate was 32.5% an increase from 30.9% in the first nine months of 2011. The higher tax rate in the first nine months of 2012 primarily reflects an increased proportion of domestic income.

Fair Value Measurements

Fair Value Measurements

NOTE J - Fair Value Measurements

Fair value represents the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Inputs to valuation techniques used to measure fair value are either observable or unobservable. These inputs have been categorized into the fair value hierarchy described below.

Level 1 – Valuations are based on inputs from quoted prices that the Company has the ability to obtain in actively traded markets for identical assets or liabilities. Since valuations are based on quoted prices that are readily and regularly available in an active market or exchange traded market, valuation of these instruments does not require a significant degree of judgment.

Level 2 – Valuations are based on inputs from quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.

Level 3 – Valuations are based on model-based techniques for which some or all of the assumptions are obtained from unobservable market information that is significant to the overall fair value measurement and which require a significant degree of management judgment.

There were no transfers of assets or liabilities between Level 1 and Level 2 of the fair value hierarchy during the nine months ended September 30, 2012. The Company’s policy is to recognize transfers between levels at the end of the reporting period.

The Company uses the following methods and assumptions to measure fair value for assets and liabilities subject to recurring fair value measurements.

Marketable Securities: The Company’s marketable debt securities consist of municipal bonds, government obligations, investment-grade corporate obligations, commercial paper, asset-backed securities and term deposits. The fair value of U.S. government obligations is determined using the market approach and is based on quoted prices in active markets and are categorized as Level 1.

The fair value of non-U.S. government bonds, municipal bonds, corporate bonds, asset-backed securities, commercial paper, and term deposits is determined using the market approach and is primarily based on matrix pricing as a practical expedient which does not rely exclusively on quoted prices for a specific security. Significant inputs used to determine fair value include interest rates, yield curves, credit rating of the security and other observable market information and are categorized as Level 2.

Derivative Financial Instruments: The Company’s derivative contracts consist of interest-rate swaps, cross currency swaps and foreign currency exchange contracts. These derivative contracts are traded over the counter and their fair value is determined using industry standard valuation models, which are based on the income approach (i.e., discounted cash flows). The significant observable inputs into the valuation models include interest rates, yield curves, currency exchange rates, credit default swap spreads and forward spot rates and are categorized as Level 2.

Assets and Liabilities Subject to Recurring Fair Value Measurement

Fair Value Disclosure of Other Financial Instruments

For financial instruments that are not recognized at fair value, the Company uses the following methods and assumptions to determine the fair value. These instruments are categorized as Level 2, except fixed-rate loans which are categorized as Level 3.

Cash and Cash Equivalents: Carrying amounts approximate fair value.

Financial Services Net Receivables: For floating-rate loans, wholesale financings, and accrued rents and other trade receivables, carrying values approximate fair values. For fixed-rate loans, fair values are estimated using the income approach by discounting cash flows to their present value based on current rates for comparable loans. Finance lease receivables and related allowance for credit losses have been excluded from the accompanying table.

Debt: The carrying amounts of financial services commercial paper, variable-rate bank loans and variable-rate term notes approximate fair value. For fixed-rate debt, fair values are estimated using the income approach by discounting cash flows to their present value based on current rates for comparable debt.

The Company’s estimate of fair value for fixed-rate loans and debt that are not carried at fair value at September 30, 2012 and December 31, 2011 was as follows:

	September 30, 2012				December 31, 2011

Derivative Financial Instruments

NOTE I - Derivative Financial Instruments

As part of its risk management strategy, the Company enters into derivative contracts to hedge exposures to fluctuations in interest rates and foreign currency exchange rates. Certain derivative instruments designated as either cash flow hedges or fair value hedges are subject to hedge accounting. Derivative instruments that are not subject to hedge accounting are held as economic hedges. The Company’s policies prohibit the use of derivatives for speculation or trading. At the inception of each hedge relationship, the Company documents its risk management objectives, procedures and accounting treatment.

The Company has elected not to offset derivative positions in the balance sheet with the same counterparty under the same master netting agreements. The Company is not required to post or receive collateral under these agreements. Exposure limits and minimum credit ratings are used to minimize the risks of counterparty default. The Company had no material exposures to default at September 30, 2012.

The Company uses regression analysis to assess effectiveness of interest-rate contracts on a quarterly basis. For foreign-exchange contracts, the Company performs quarterly assessments to ensure that critical terms continue to match. All components of the derivative instrument’s gain or loss are included in the assessment of hedge effectiveness. Gains or losses on the ineffective portion of cash flow hedges are recognized currently in earnings. Hedge accounting is discontinued prospectively when the Company determines that a derivative financial instrument has ceased to be a highly effective hedge.

Interest-Rate Contracts: The Company enters into various interest-rate contracts, including interest-rate swaps and cross currency interest-rate swaps. Interest-rate swaps involve the exchange of fixed for floating rate or floating for fixed rate interest payments based on the contractual notional amounts in a single currency. Cross currency interest-rate swaps involve the exchange of notional amounts and interest payments in different currencies. The Company is exposed to interest-rate and exchange-rate risk caused by market volatility as a result of its borrowing activities. The objective of these contracts is to mitigate the fluctuations on earnings, cash flows and fair value of borrowings. Net amounts paid or received are reflected as adjustments to interest expense.

At September 30, 2012, the notional amount of the Company’s interest-rate contracts was $3,135.6. Notional maturities for all interest-rate contracts are $56.8 for the remainder of 2012, $716.9 for 2013, $1,342.8 for 2014, $775.4 for 2015, $39.3 for 2016 and $204.4 thereafter. The majority of these contracts are floating to fixed swaps that effectively convert an equivalent amount of commercial paper and other variable rate debt to fixed rates.

Foreign-Exchange Contracts: The Company enters into foreign-exchange contracts to hedge certain anticipated transactions and assets and liabilities denominated in foreign currencies, particularly the Canadian dollar, the euro, the British pound, the Australian dollar and the Mexican peso. The objective is to reduce fluctuations in earnings and cash flows associated with changes in foreign currency exchange rates. At September 30, 2012, the notional amount of the outstanding foreign-exchange contracts was $188.1. Foreign-exchange contracts mature within one year.

The following table presents the balance sheet classifications and fair value of derivative financial instruments designated under hedge accounting:

	September 30, 2012				December 31, 2011
	Assets		Liabilities		Assets		Liabilities
Derivatives designated under hedge accounting:

Fair Value Hedges

Changes in the fair value of derivatives designated as fair value hedges are recorded in earnings together with the changes in fair value of the hedged item attributable to the risk being hedged. The expense or (income) recognized in earnings related to fair value hedges was included in interest and other borrowing expenses in the Financial Services segment of the Consolidated Statements of Comprehensive Income as follows:

	Three Months Ended						Nine Months Ended
	September 30						September 30
	2012			2011			2012			2011
Interest-rate swaps	$	(2.4	)	$	(5.2	)	$	(4.0	)	$	(4.7	)
Term notes	$	3.2		$	4.9		$	4.7		$	4.2

Cash Flow Hedges

Substantially all of the Company’s interest-rate contracts and some foreign-exchange contracts have been designated as cash flow hedges. Changes in the fair value of derivatives designated as cash flow hedges are recorded in accumulated other comprehensive income to the extent such hedges are considered effective. The maximum length of time over which the Company is hedging its exposure to the variability in future cash flows is 5.7 years.

Amounts in accumulated other comprehensive income are reclassified into net income in the same period in which the hedged transaction affects earnings. Net realized gains and losses from interest-rate contracts are recognized as an adjustment to interest expense. Net realized gains and losses from foreign-exchange contracts are recognized as an adjustment to cost of sales or to Financial Services interest expense, consistent with the hedged transaction. The ineffective portions were a gain of $.2 and a loss of $.1 during the third quarter of 2012 and 2011, respectively, and were gains of $.4 and $.7 during the first nine months of 2012 and 2011, respectively.

The following table presents the pre-tax effects of derivative instruments recognized in other comprehensive income (OCI):

Financial Services:
Interest and other borrowing expenses	$	(16.3	)				$	20.2
	$	(16.3	)	$	(.7	)	$	20.2	$	(3.3	)

The amount of loss recorded in accumulated OCI at September 30, 2012 that is estimated to be reclassified to interest expense or cost of sales in the following 12 months if interest rates and exchange rates remain unchanged is approximately $36.8, net of taxes. The fixed interest earned on finance receivables will offset the amount recognized in interest expense, resulting in a stable interest margin consistent with the Company’s risk management strategy.

Economic Hedges

For other risk management purposes, the Company enters into derivative instruments not designated as hedges that do not qualify for hedge accounting. These derivative instruments are used to mitigate the risk of market volatility arising from borrowings and foreign currency denominated transactions. Changes in the fair value of economic hedges are recorded in earnings in the period in which the change occurs.

The (income) expense recognized in earnings related to economic hedges is as follows:

	Three Months Ended						Nine Months Ended

Product Support Liabilities

NOTE E - Product Support Liabilities

Product support liabilities are estimated future payments related to product warranties, optional extended warranties and repair and maintenance (R&M) contracts. The Company generally offers one-year warranties covering most of its vehicles and related aftermarket parts. Specific terms and conditions vary depending on the product and the country of sale. Optional extended warranty and R&M contracts can be purchased for periods which generally range up to five years. Warranty expenses and reserves are estimated and recorded at the time products or contracts are sold based on historical data regarding the source, frequency and cost of claims, net of any recoveries. Revenue from extended warranty contracts is deferred and recognized to income on a straight-line basis over the contract period. Warranty costs on these contracts are recognized as incurred. The Company periodically assesses the adequacy of its recorded liabilities and adjusts them as appropriate to reflect actual experience.

Changes in product support liabilities are summarized as follows:

	2012			2011
Balance at January 1	$	448.7		$	372.2
