Receivables [Abstract]
Finance and Other Receivables	NOTE B – Finance and Other Receivables The Company’s finance and other receivables include the following: September December 31 2017 2016 Retail loans $ 2,855.2 $ 2,948.6 Retail direct financing leases 1,529.7 1,644.7 Dealer wholesale financing 1,012.8 760.3 Dealer master notes 25.8 23.8 Operating lease receivables and other 72.5 65.9 Unearned interest on finance leases (133.1 ) (149.0 ) 5,362.9 5,294.3 Less allowance for credit losses: Loans and leases (54.7 ) (56.3 ) Dealer wholesale financing (2.7 ) (2.0 ) Operating lease receivables and other (1.1 ) (1.1 ) $ 5,304.4 $ 5,234.9 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, no finance receivables more than 90 days past due were accruing interest at September 30, 2017 or December 31, 2016. 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 if the customer makes scheduled payments for three months and collection of remaining amounts is considered probable (if contractually modified). Payments received while the finance receivable is 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 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 in the normal course of its 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 On average, modifications extended contractual terms by approximately three months in both 2017 and 2016, and did not have a significant effect on the weighted average term or interest rate of the total portfolio at September 30, 2017 or 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 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 status. Impaired accounts classified as TDRs which have been performing for 90 consecutive days are placed on accrual status if it is deemed probable that the Company will collect all principal and interest payments. 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 a 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 its portfolio 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 against the allowance for credit losses when, in the judgment of management, they are considered uncollectible, which generally occurs 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 a partial charge-off. The charge-off is determined by comparing the fair value of the collateral, less cost to sell, to the recorded investment. 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 retail accounts of customers 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 $ 2.0 $ 8.5 $ 47.8 $ 1.1 $ 59.4 Provision (benefit) for losses .7 (.6 ) 9.8 .2 10.1 Charge-offs (11.8 ) (.3 ) (12.1 ) Recoveries 1.0 .1 1.1 Balance at September 30 $ 2.7 $ 7.9 $ 46.8 $ 1.1 $ 58.5 2016 Dealer Customer Wholesale Retail Retail Other* Total Balance at January 1 $ 2.7 $ 9.2 $ 46.3 $ 1.1 $ 59.3 (Benefit) provision for losses (.4 ) (.5 ) 9.2 .8 9.1 Charge-offs (9.9 ) (.7 ) (10.6 ) Recoveries .9 .9 Balance at September 30 $ 2.3 $ 8.7 $ 46.5 $ 1.2 $ 58.7 * Operating lease and other trade receivables Information regarding finance receivables evaluated and the associated allowances determined collectively and individually is as follows: Dealer Customer At September 30, 2017 Wholesale Retail Retail Total Recorded investment for impaired finance receivables evaluated individually $ 25.8 $ 25.8 Allowance for impaired finance receivables determined individually $ 3.6 $ 3.6 Recorded investment for finance receivables evaluated collectively $ 1,012.8 $ 1,145.5 $ 3,106.3 $ 5,264.6 Allowance for finance receivables determined collectively $ 2.7 $ 7.9 $ 43.2 $ 53.8 Dealer Customer At December 31, 2016 Wholesale Retail Retail Total Recorded investment for impaired finance receivables evaluated individually $ 31.4 $ 31.4 Allowance for impaired finance receivables determined individually $ 2.5 $ 2.5 Recorded investment for finance receivables evaluated collectively $ 760.3 $ 1,248.7 $ 3,188.0 $ 5,197.0 Allowance for finance receivables determined collectively $ 2.0 $ 8.5 $ 45.3 $ 55.8 The recorded investment for finance receivables that are on non-accrual status is as follows: September 30 December 31 2017 2016 Fleet $ 24.9 $ 29.9 Owner/operator .9 1.5 $ 25.8 $ 31.4 Impaired Loans Impaired loans are summarized below. The impaired loans with a specific reserve represent the unpaid principal balance.

The Company’s portfolio assets are diversified over a large number of customers and dealers with no single customer or dealer balance representing over 10% of the total portfolio assets as of September 30, 2017 or December 31, 2016. 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 there is 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. The tables below summarize the Company’s finance receivables by credit quality indicator and portfolio class. Dealer Customer Retail Owner/ At September 30, 2017 Wholesale Retail Fleet Operator Total Performing $ 1,012.8 $ 1,145.5 $ 2,632.3 $ 426.2 $ 5,216.8 Watch 47.3 .5 47.8 At-risk 24.9 .9 25.8 $ 1,012.8 $ 1,145.5 $ 2,704.5 $ 427.6 $ 5,290.4 Dealer Customer Retail Owner/ At December 31, 2016 Wholesale Retail Fleet Operator Total Performing $ 757.4 $ 1,248.7 $ 2,761.9 $ 421.0 $ 5,189.0 Watch 2.9 4.4 .7 8.0 At-risk 30.0 1.4 31.4 $ 760.3 $ 1,248.7 $ 2,796.3 $ 423.1 $ 5,228.4 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. Dealer Customer Retail Owner/ At September 30, 2017 Wholesale Retail Fleet Operator Total Current and up to 30 days past due $ 1,012.8 $ 1,145.5 $ 2,691.5 $ 426.4 $ 5,276.2 31 – 60 days past due 4.3 .6 4.9 Greater than 60 days past due 8.7 .6 9.3 $ 1,012.8 $ 1,145.5 $ 2,704.5 $ 427.6 $ 5,290.4 Dealer Customer Retail Owner/ At December 31, 2016 Wholesale Retail Fleet Operator Total Current and up to 30 days past due $ 760.3 $ 1,248.7 $ 2,784.5 $ 421.4 $ 5,214.9 31 – 60 days past due 5.8 .9 6.7 Greater than 60 days past due 6.0 .8 6.8 $ 760.3 $ 1,248.7 $ 2,796.3 $ 423.1 $ 5,228.4 Troubled Debt Restructurings The balance of TDRs was $16.9 at September 30, 2017 and $18.1 at December 31, 2016. There were no new TDRs in the three months ended September 30, 2017. At modification date, the pre-modification and post-modification recorded investment balances for finance receivables modified during the periods by portfolio class are as follows: Three Months Ended Nine Months Ended September 30, 2017 September 30, 2017 Recorded Investment Recorded Investment Pre-Modification Post-Modification Pre-Modification Post-Modification Fleet $ 8.8 $ 8.8 Owner/operator $ 8.8 $ 8.8 Three Months Ended Nine Months Ended September 30, 2016 September 30, 2016 Recorded Investment Recorded Investment Pre-Modification Post-Modification Pre-Modification Post-Modification Fleet $ 8.0 $ 8.0 $ 14.8 $ 14.8 Owner/operator $ 8.0 $ 8.0 $ 14.8 $ 14.8 The effect on the allowance for credit losses from such modifications was not significant at September 30, 2017 and 2016. The post-modification recorded investment of finance receivables modified as TDRs during the previous twelve months that subsequently defaulted (i.e. became more than 30 days past due) during the periods by portfolio class are as follows: Nine Months Ended September 30 2017 2016 Fleet $ 4.6 Owner/operator $ 4.6 There were $4.6 of finance receivables modified as TDRs during the last twelve months that subsequently defaulted in the nine months ended September 30, 2017, resulting in a specific reserve for one fleet customer of $1.6 as of September 30, 2017. There were $1.4 and $.2 of finance receivables modified as TDRs during the previous twelve months that subsequently defaulted and were charged-off in the nine months ended September 30, 2017 and 2016, respectively. Repossessions When the Company determines that a customer is not likely to meet its contractual commitments, the Company repossesses the vehicles which serve as collateral for the loans, finance leases and equipment under operating lease. The Company records the vehicles as used truck inventory included in Other assets on the Balance Sheets. The balance of repossessed units was $13.4 at September 30, 2017 and $15.5 at December 31, 2016. Proceeds from sales of repossessed assets were $20.7 and $13.0 for the nine months ended September 30, 2017 and 2016, respectively. These amounts are included in Proceeds from disposal of equipment on the Statements of Cash Flows. Write-downs of repossessed equipment on operating leases are recorded as impairments and included in Depreciation and other rental expenses on the Statements of Comprehensive Income and Retained Earnings.

Related Party Transactions [Abstract]
Transactions with PACCAR and Affiliates	NOTE C – Transactions with PACCAR and Affiliates The Company and PACCAR are parties to a Support Agreement that obligates PACCAR to provide, when required, financial assistance to the Company to ensure that the Company maintains a ratio of earnings to fixed charges (as defined in the Support Agreement) of at least 1.25 to 1 for any fiscal year. The required ratio for the nine months ended September 30, 2017 and full year 2016 was met without assistance. The Support Agreement also requires PACCAR to own, directly or indirectly, all outstanding voting stock of the Company. Periodically, the Company makes loans to, borrows from and has intercompany transactions with PACCAR. In addition, the Company periodically loans funds to certain foreign finance and leasing affiliates of PACCAR. These various affiliates have Support Agreements with PACCAR, similar to the Company’s Support Agreement with PACCAR. The foreign affiliates operate in the United Kingdom, the Netherlands, Mexico, Canada and Australia. Loans to these foreign affiliates during 2017 and 2016 were denominated in United States dollars. The foreign affiliates primarily provide financing and leasing of PACCAR manufactured trucks and related equipment sold through the DAF, Kenworth and Peterbilt independent dealer networks in Europe, Mexico, Canada and Australia. The Company will not make aggregate loans to the foreign affiliates in excess of the equivalent of $500.00 U.S. dollars, unless the amount in excess of such limit is guaranteed by PACCAR. The Company periodically reviews the funding alternatives for these affiliates, and these limits may be revised in the future. Amounts outstanding at September 30, 2017 and December 31, 2016, including balances with foreign finance affiliates operating in the United Kingdom, the Netherlands, Mexico, Canada and Australia, are summarized below: September 30 December 31 2017 2016 Due from PACCAR and affiliates Loans due from PACCAR $ 723.0 $ 756.5 Loans due from foreign finance affiliates 347.0 413.0 Direct financing leases due from affiliate .6 .5 Tax-related receivable due from PACCAR 2.4 7.1 Receivables 41.4 88.4 $ 1,114.4 $ 1,265.5 Due to PACCAR and affiliates Payables $ 15.6 $ 16.2 $ 15.6 $ 16.2 The Company is included in the consolidated federal income tax return of PACCAR. The tax-related receivable due from PACCAR represents the related tax benefit to be settled with PACCAR. The Company provides direct financing leases to dealer locations operated by an affiliate of PACCAR. PACCAR charges the Company for certain administrative services it provides. These costs were charged to the Company based upon the Company’s specific use of the services and PACCAR’s cost. The Company’s principal office is located in the corporate headquarters building of PACCAR (owned by PACCAR). The Company also leases office space from another facility owned by PACCAR and four facilities leased by PACCAR.

Fair Value Disclosures [Abstract]
Fair Value Measurements	NOTE E – 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 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 nine months ended September 30, 2017. The Company’s policy is to recognize transfers between levels at the end of the reporting period. Assets and Liabilities Subject to Non-recurring and Recurring Fair Value Measurement Impaired loans and used trucks held for sale are measured on a non-recurring basis. Derivative contracts are measured on a recurring basis. The Company’s assets and liabilities subject to fair value measurements are as follows: September 30 December 31 Level 2 2017 2016 Assets: Impaired loans, net of specific reserves (2017 - $1.8 and 2016 - $1.0) $ 5.4 $ 1.9 Used trucks held for sale 69.5 100.4 Derivative contracts 1.8 2.4 Liabilities: Derivative contracts $ 3.5 $ 4.1 The Company uses the following methods and assumptions to measure fair value for assets and liabilities subject to non-recurring and recurring fair value measurements. Impaired Loans: Impaired loans that are individually evaluated are generally considered collateral dependent. Accordingly, the evaluation of individual reserves on such loans considers the fair value of the associated collateral (estimated sales proceeds less the costs to sell). Used Trucks Held for Sale: The carrying amount of used trucks held for sale is written down as necessary to reflect the fair value less costs to sell. The Company determines the fair value of used trucks from a pricing matrix, which is based on the market approach. The significant observable inputs into the valuation model are recent sales prices of comparable units and the condition of the vehicles. Used truck impairments related to units held at September 30, 2017 and 2016 were $16.8 and $12.7 during the first nine months of 2017 and 2016, respectively. These assets, which are shown in the above table when they are written down to fair value less costs to sell, are categorized as Level 2 and are included in Other assets on the Balance Sheets. Derivative Financial Instruments: The Company’s derivative financial instruments consist of interest-rate swaps and are carried at fair value. 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 and credit default swap spreads. These contracts are categorized as Level 2 and are included in Other assets and Accounts payable, accrued expenses and other on the Balance Sheets. 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 cash which is categorized as Level 1 and fixed rate loans which are categorized as Level 3. Cash: Carrying amounts approximate fair value. Net Receivables: For floating rate loans, dealer wholesale financings and operating lease 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. Commercial Paper and Medium-Term Notes: The carrying amounts of the Company’s commercial paper and variable medium-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 was as follows: September 30, 2017 December 31, 2016 Carrying Fair Carrying Fair Amount Value Amount Value Assets: Due from PACCAR $ 723.0 $ 723.1 $ 648.0 $ 648.4 Due from foreign finance affiliates 172.0 173.6 218.0 219.4 Fixed rate loans 2,706.2 2,710.8 2,796.0 2,816.2 Liabilities: Fixed rate debt $ 4,092.4 $ 4,087.9 $ 4,193.1 $ 4,191.4

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	NOTE F – Derivative Financial Instruments Interest-rate contracts 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. The Company is exposed to interest 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, 2017, the notional amount of these contracts totaled $801.7 with amounts expiring over the next ten years. Notional maturities for all interest-rate contracts are $325.0 for 2018, $243.0 for 2019, $40.0 for 2020, $62.6 for 2021, $105.0 for 2022 and $26.1 thereafter. The notional amount is used to measure the volume of these contracts and does not represent exposure to credit loss. The following table presents the balance sheet classification, fair value and gross and net amounts of derivative financial instruments: September 30, 2017 December 31, 2016 Interest-rate contracts: Assets Liabilities Assets Liabilities Other assets $ 1.8 $ 2.4 Accounts payable, accrued expenses and other $ 3.5 $ 4.1 Gross amounts recognized in Balance Sheets 1.8 3.5 2.4 4.1 Less amounts not offset in financial instruments: (.6 ) (.6 ) (.6 ) (.6 ) Pro-forma net amount $ 1.2 $ 2.9 $ 1.8 $ 3.5 All of the Company’s interest-rate 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. 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 was $1.8 and $2.4 at September 30, 2017 and December 31, 2016, respectively. The Company uses regression analysis to assess effectiveness of interest-rate contracts on a quarterly basis. 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 in current earnings and were immaterial for the nine months ended September 30, 2017 and 2016. Hedge accounting is discontinued prospectively when the Company determines that a derivative financial instrument has ceased to be a highly effective hedge. Cash Flow Hedges Certain of the Company’s interest-rate 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. The maximum length of time over which the Company is hedging its exposure to the variability in future cash flows is ten years. Amounts in AOCI are reclassified into net income in the same period in which the hedged transaction affects earnings. The amount of loss recorded in AOCI at September 30, 2017 that is estimated to be reclassified to interest expense in the following 12 months if interest rates remain unchanged is nil, 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 interest rate risk management strategy. 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 were included in Interest and other borrowing costs as follows: Three Months Ended Nine Months Ended September 30 September 30 2017 2016 2017 2016 Interest-rate swaps $ .4 $ 3.7 $ 1.0 $ (1.3 ) Term notes $ (.2 ) $ (3.8 ) $ (.6 ) $ .7

Receivables [Abstract]
Finance Receivables Allowance for Credit Losses	Allowance for Credit Losses The Company continuously monitors the payment performance of 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 in the normal course of its 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 On average, modifications extended contractual terms by approximately three months in both 2017 and 2016, and did not have a significant effect on the weighted average term or interest rate of the total portfolio at September 30, 2017 or 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 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 status. Impaired accounts classified as TDRs which have been performing for 90 consecutive days are placed on accrual status if it is deemed probable that the Company will collect all principal and interest payments. 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 a 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 its portfolio 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 against the allowance for credit losses when, in the judgment of management, they are considered uncollectible, which generally occurs 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 a partial charge-off. The charge-off is determined by comparing the fair value of the collateral, less cost to sell, to the recorded investment.
