Investments, Debt and Equity Securities [Abstract]
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. 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 third-party 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 March 31, 2017 and December 31, 2016 consisted of the following: At March 31, 2017 AMORTIZED UNREALIZED UNREALIZED FAIR U.S. tax-exempt $ 583.5 $ 1.2 $ .9 $ 583.8 U.S. corporate securities 55.2 .2 55.4 U.S. government and agency securities 16.5 16.5 Non-U.S. 348.0 1.6 .2 349.4 Non-U.S. 96.3 .5 96.8 Other debt securities 104.5 .1 .1 104.5 $ 1,204.0 $ 3.6 $ 1.2 $ 1,206.4 At December 31, 2016 AMORTIZED UNREALIZED UNREALIZED FAIR U.S. tax-exempt $ 597.9 $ .2 $ 3.1 $ 595.0 U.S. corporate securities 47.6 .2 47.8 U.S. government and agency securities 16.0 16.0 Non-U.S. 306.9 1.5 .4 308.0 Non-U.S. 97.6 .6 98.2 Other debt securities 75.9 .2 .2 75.9 $ 1,141.9 $ 2.7 $ 3.7 $ 1,140.9 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. Gross realized gains were $.5 and $.8 and gross realized losses were $.2 and $.1 for the three months ended March 31, 2017 and 2016, respectively. Marketable debt securities with continuous unrealized losses and their related fair values were as follows: March 31, 2017 December 31, 2016 LESS THAN TWELVE MONTHS LESS THAN TWELVE MONTHS Fair value $ 395.4 $ 615.5 Unrealized losses 1.2 3.7 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 March 31, 2017 were as follows: Maturities: AMORTIZED FAIR Within one year $ 308.2 $ 308.4 One to five years 886.6 888.8 Six to ten years .1 .1 More than ten years 9.1 9.1 $ 1,204.0 $ 1,206.4

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 in the normal course 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 (TDR). 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 three months in 2017 and four months in 2016 and did not have a significant effect on the weighted average term or interest rate of the total portfolio at March 31, 2017 and December 31, 2016. 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 truck inventory 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 periodic reporting of the wholesale dealer’s financial condition, conducts periodic audits of the trucks being financed and in many cases, obtains 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 that 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. Generally, impaired accounts are on non-accrual Impaired receivables are generally 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 recorded investment, 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. The Company evaluates finance receivables that are not individually impaired on collective basis 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, a 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 matrix and categorizes the fair value as Level 2 in the hierarchy of fair value measurement. The pricing matrix is reviewed quarterly and updated as appropriate. The pricing matrix considers the make, model and year of the equipment as well as recent sales prices of comparable equipment sold individually, which is the lowest unit of account, 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 charge-off charge-off. charge-off For the following credit quality disclosures, finance receivables are classified into two portfolio segments, wholesale and retail. The retail portfolio is further segmented into dealer retail and customer retail. The dealer wholesale segment consists of truck inventory financing to PACCAR dealers. The dealer retail segment consists of loans and leases to participating dealers and franchises that use the proceeds to fund customers’ acquisition of commercial vehicles and related equipment. The customer retail segment consists of loans and leases directly to customers for the acquisition of commercial vehicles and related equipment. Customer retail receivables are further segregated between fleet and owner/operator classes. The fleet class consists of customer retail accounts operating more than five trucks. All other customer retail accounts are considered owner/operator. These two classes have similar measurement attributes, risk characteristics and common methods to monitor and assess credit risk. The allowance for credit losses is summarized as follows: 2017 DEALER CUSTOMER WHOLESALE RETAIL RETAIL OTHER* TOTAL Balance at January 1 $ 5.5 $ 9.6 $ 87.5 $ 8.6 $ 111.2 Provision for losses (.3 ) 5.9 .3 5.9 Charge-offs (6.5 ) (.3 ) (6.8 ) Recoveries 1.4 1.4 Currency translation and other .1 .1 2.0 2.2 Balance at March 31 $ 5.6 $ 9.4 $ 90.3 $ 8.6 $ 113.9 2016 DEALER CUSTOMER WHOLESALE RETAIL RETAIL OTHER* TOTAL Balance at January 1 $ 7.3 $ 10.3 $ 88.9 $ 8.3 $ 114.8 Provision for losses (.5 ) (.5 ) 3.2 1.2 3.4 Charge-offs (5.4 ) (.5 ) (5.9 ) Recoveries .1 .6 .7 Currency translation and other .2 .1 1.2 .4 1.9 Balance at March 31 $ 7.1 $ 9.9 $ 88.5 $ 9.4 $ 114.9 * Operating leases and other trade receivables.

Segment Reporting [Abstract]
Segment Information	NOTE H - Segment Information PACCAR operates in three principal segments: Truck, Parts and Financial Services. The Company evaluates the performance of its Truck and Parts segments based on operating profits, which excludes investment income, other income and expense, the EC charge and income taxes. The Financial Services segment’s performance is evaluated based on income before income taxes. The accounting policies of the reportable segments are the same as those applied in the consolidated financial statements as described in Note A of the Company’s Annual Report on Form 10-K Truck and Parts The Truck segment includes the design and manufacture of high-quality, light-, medium- and heavy-duty commercial trucks and the Parts segment includes the distribution of aftermarket parts for trucks and related commercial vehicles, both of which are sold through the same network of independent dealers. These segments derive a large proportion of their revenues and operating profits from operations in North America and Europe. The Truck segment incurs substantial costs to design, manufacture and sell trucks to its customers. The sale of new trucks provides the Parts segment with the basis for parts sales that may continue over the life of the truck, but are generally concentrated in the first five years after truck delivery. To reflect the benefit the Parts segment receives from costs incurred by the Truck segment, certain expenses are allocated from the Truck segment to the Parts segment. The expenses allocated are based on a percentage of the average annual expenses for factory overhead, engineering, research and development and selling, general and administrative (SG&A) expenses for the preceding five years. The allocation is based on the ratio of the average parts direct margin dollars (net sales less material and labor costs) to the total truck and parts direct margin dollars for the previous five years. The Company believes such expenses have been allocated on a reasonable basis. Truck segment assets related to the indirect expense allocation are not allocated to the Parts segment. Financial Services The Financial Services segment derives its earnings primarily from financing or leasing of PACCAR products and services provided to truck customers and dealers. Revenues are primarily generated from operations in North America and Europe. Other Included in Other is the Company’s industrial winch manufacturing business. Also within this category are other sales, income and expense not attributable to a reportable segment, including the EC charge and a portion of corporate expenses.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	NOTE I - Derivative Financial Instruments As part of its risk management strategy, the Company enters into derivative contracts to hedge against interest rates and foreign currency risk. 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. All of the Company’s interest-rate and certain foreign-exchange contracts are transacted under International Swaps and Derivatives Association (ISDA) master agreements. Each agreement permits the net settlement of amounts owed in the event of default and certain other termination events. For derivative financial instruments, the Company has elected not to offset derivative positions in the balance sheet with the same counterparty under the same agreements and is not required to post or receive collateral. Exposure limits and minimum credit ratings are used to minimize the risks of counterparty default. The Company’s maximum exposure to potential default of its swap counterparties is limited to the asset position of its swap portfolio. The asset position of the Company’s swap portfolio is $68.7 at March 31, 2017. 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: At March 31, 2017, the notional amount of the Company’s interest-rate contracts was $3,007.6. Notional maturities for all interest-rate contracts are $551.6 for the remainder of 2017, $1,063.4 for 2018, $907.8 for 2019, $288.8 for 2020, $196.0 for 2021 and nil thereafter. Foreign-Exchange Contracts: The following table presents the balance sheet classification, fair value, gross and pro forma net amounts of derivative financial instruments: March 31, 2017 December 31, 2016 ASSETS LIABILITIES ASSETS LIABILITIES Derivatives designated under hedge accounting: Interest-rate contracts: Financial Services: Other assets $ 68.7 $ 109.7 Deferred taxes and other liabilities $ 49.8 $ 46.3 Foreign-exchange contracts: Truck, Parts and Other: Other current assets .7 3.9 Accounts payable, accrued expenses and other 12.8 1.9 $ 69.4 $ 62.6 $ 113.6 $ 48.2 Economic hedges: Interest-rate contracts: Financial Services: Deferred taxes and other liabilities $ .1 $ .1 Foreign-exchange contracts: Truck, Parts and Other: Other current assets $ .7 $ .8 Accounts payable, accrued expenses and other 1.1 .3 Financial Services: Other assets 1.2 4.0 Deferred taxes and other liabilities 7.5 .7 $ 1.9 $ 8.7 $ 4.8 $ 1.1 Gross amounts recognized in Balance Sheet $ 71.3 $ 71.3 $ 118.4 $ 49.3 Less amounts not offset in financial instruments: Truck, Parts and Other: Foreign-exchange contracts (.8 ) (.8 ) (1.0 ) (1.0 ) Financial Services: Interest-rate contracts (14.1 ) (14.1 ) (15.4 ) (15.4 ) Foreign-exchange contracts (.8 ) (.8 ) (.1 ) (.1 ) Pro forma net amount $ 55.6 $ 55.6 $ 101.9 $ 32.8 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 (income) or expense 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 (Loss) as follows: Three Months Ended March 31, 2017 2016 Interest-rate swaps $ 1.3 $ (2.0 ) Term notes (1.3 ) 1.6 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 AOCI to the extent such hedges are considered effective. Amounts in AOCI are reclassified into net income in the same period in which the hedged transaction affects earnings. The maximum length of time over which the Company is hedging its exposure to the variability in future cash flows is 4.4 years. For the quarters ended March 31, 2017 and 2016, the Company recognized no gains and losses or losses on the ineffective portion. The following table presents the pre-tax Three Months Ended March 31, 2017 2016 INTEREST- FOREIGN- INTEREST- FOREIGN- RATE EXCHANGE RATE EXCHANGE CONTRACTS CONTRACTS CONTRACTS CONTRACTS Gain (loss) recognized in OCI: Truck, Parts and Other $ (18.7 ) $ .3 Financial Services $ (45.0 ) $ (61.7 ) $ (45.0 ) $ (18.7 ) $ (61.7 ) $ .3 Expense (income) reclassified out of AOCI into income was as follows: Three Months Ended March 31, 2017 2016 INTEREST- FOREIGN- INTEREST- FOREIGN- RATE EXCHANGE RATE EXCHANGE CONTRACTS CONTRACTS CONTRACTS CONTRACTS Truck, Parts and Other: Net sales and revenues $ 4.2 $ (4.8 ) Cost of sales and revenues .1 Interest and other (income) expense, net 1.7 Financial Services: Interest and other borrowing expenses $ 45.8 $ 57.9 $ 45.8 $ 4.3 $ 57.9 $ (3.1 ) The amount of loss recorded in AOCI at March 31, 2017 that is estimated to be reclassified into earnings in the following 12 months if interest rates and exchange rates remain unchanged is approximately $8.8, 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. The amount of losses reclassified out of AOCI into net income based on the probability that the original forecasted transactions would not occur was nil and $.6 for the quarters ended March 31, 2017 and 2016, respectively. Economic Hedges For other risk management purposes, the Company enters into derivative instruments 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. For the quarters ended March 31, 2017 and 2016, expense (income) recognized in earnings related to interest-rate contracts was nil for both periods. The expense (income) recognized in earnings related to foreign-exchange contracts was as follows: Three Months Ended March 31, 2017 2016 Truck, Parts and Other: Cost of sales and revenues $ 3.3 $ 1.0 Interest and other (income) expense, net 31.5 (.1 ) Financial Services: Interest and other borrowing expenses 39.2 2.4 Selling, general and administrative (3.9 ) (2.1 ) $ 70.1 $ 1.2

Fair Value Disclosures [Abstract]
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 Level 1 – Valuations are based on 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 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 indirect 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 three months ended March 31, 2017. The Company’s policy is to recognize transfers between levels at the end of the reporting period.

Compensation and Retirement Disclosure [Abstract]
Employee Benefit Plans	NOTE K - Employee Benefit Plans The Company has several defined benefit pension plans, which cover a majority of its employees. The following information details the components of net pension expense for the Company’s defined benefit plans: Three Months Ended March 31, 2017 2016 Service cost $ 23.8 $ 21.9 Interest on projected benefit obligation 20.4 23.6 Expected return on assets (39.8 ) (35.6 ) Amortization of prior service costs .3 .3 Recognized actuarial loss 6.7 6.5 Net pension expense $ 11.4 $ 16.7 On January 1, 2017, the Company changed the method used to estimate service cost and interest cost components of pension expense from a single weighted-average method, which is a single discount rate determined at the pension plans measurement date, to an individual spot rate approach, which applies specific spot rates along the yield curve to the relevant projected cash flows. This approach is a more precise measurement of net periodic benefit costs and does not impact the benefit obligation. The Company considers this a change in estimate inseparable from a change in accounting principle and is being accounted for prospectively. This change will lower net pension expense by approximately $15.0 in 2017. During the three months ended March 31, 2017 and 2016, the Company contributed $4.9 and $5.1 to its pension plans, respectively.

Accounting Policies [Abstract]
Investment in Marketable Debt Securities	The Company’s investments in marketable debt securities are classified as available-for-sale. 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 third-party 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.

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 in the normal course 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 (TDR). 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 three months in 2017 and four months in 2016 and did not have a significant effect on the weighted average term or interest rate of the total portfolio at March 31, 2017 and December 31, 2016. 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 truck inventory 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 periodic reporting of the wholesale dealer’s financial condition, conducts periodic audits of the trucks being financed and in many cases, obtains 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 that 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. Generally, impaired accounts are on non-accrual Impaired receivables are generally 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 recorded investment, 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. The Company evaluates finance receivables that are not individually impaired on collective basis 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, a 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 matrix and categorizes the fair value as Level 2 in the hierarchy of fair value measurement. The pricing matrix is reviewed quarterly and updated as appropriate. The pricing matrix considers the make, model and year of the equipment as well as recent sales prices of comparable equipment sold individually, which is the lowest unit of account, 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 charge-off charge-off. charge-off
Product Support Liabilities	Product support liabilities include estimated future payments related to product warranties and deferred revenues on 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. For vehicles equipped with engines manufactured by PACCAR, the Company generally offers two year warranties on the engine. 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. The Company periodically assesses the adequacy of its recorded liabilities and adjusts them as appropriate to reflect actual experience. Revenue from extended warranty and R&M contracts is deferred and recognized to income generally on a straight-line basis over the contract period. Warranty and R&M costs on these contracts are recognized as incurred.
Derivative Financial Instruments	As part of its risk management strategy, the Company enters into derivative contracts to hedge against interest rates and foreign currency risk. 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. All of the Company’s interest-rate and certain foreign-exchange contracts are transacted under International Swaps and Derivatives Association (ISDA) master agreements. Each agreement permits the net settlement of amounts owed in the event of default and certain other termination events. For derivative financial instruments, the Company has elected not to offset derivative positions in the balance sheet with the same counterparty under the same agreements and is not required to post or receive collateral. Exposure limits and minimum credit ratings are used to minimize the risks of counterparty default. The Company’s maximum exposure to potential default of its swap counterparties is limited to the asset position of its swap portfolio. The asset position of the Company’s swap portfolio is $68.7 at March 31, 2017. 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.
Fair Value Measurement Policy	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 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 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 indirect 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 three months ended March 31, 2017. 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.
