Accounting Policies [Abstract]
Significant Accounting Policies	NOTE A – SIGNIFICANT ACCOUNTING POLICIES Description of Operations and Basis of Presentation PACCAR Financial Corp. (the “Company”), is a wholly owned subsidiary of PACCAR Inc (“PACCAR”). The Company primarily provides financing of PACCAR manufactured trucks and related equipment sold by authorized dealers. The Company also finances dealer inventories of transportation equipment and franchises Kenworth and Peterbilt dealerships to engage in full-service and finance leasing. The operations of the Company are fundamentally affected by its relationship with PACCAR. Due to the nature of the Company’s business, customers are concentrated in the transportation industry throughout the United States. Generally, all receivables are collateralized by the equipment being financed. The risk of credit losses related to this concentration has been considered in establishing the allowance for credit losses. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Finance and Other Receivables: Loans – Loans represent fixed or floating rate loans to customers or dealers collateralized by the vehicles purchased and are recorded at amortized cost. Finance leases – Finance leases are retail direct financing leases and sales-type finance leases, which lease equipment to retail customers and dealers. These leases are reported as the sum of minimum lease payments receivable and estimated residual value of the property subject to the contracts, reduced by unearned interest which is shown separately. Dealer wholesale financing – Dealer wholesale financing is floating-rate wholesale loans to Kenworth and Peterbilt dealers for new and used trucks and are recorded at amortized cost. The loans are collateralized by the trucks being financed. Operating lease receivables – Operating lease receivables and other include monthly rentals due on operating leases, unamortized loan and lease origination costs, interest on loans and other amounts due within one year in the normal course of business. 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 considered TDRs. On average, modifications extended contractual terms by approximately four months in 2018 and three months in 2017 and did not have a significant effect on the weighted average term or interest rate of the total portfolio at December 31, 2018 or 2017. 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. Revenue Recognition Interest income from finance and other receivables is recognized using the interest method. Certain loan and lease origination costs are deferred and amortized to interest income over the expected life of the contracts, generally 36 to 60 months, using the straight-line method which approximates the interest method. For operating leases, rental revenue is recognized on a straight-line basis over the lease term. 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 December 31, 2018 or December 31, 2017. 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. The Company recognizes revenue on the sale of used trucks acquired from PACCAR truck division customers as part of new truck sales packages when the used trucks are invoiced and delivered to a customer. Equipment on Operating Leases Equipment on operating leases is recorded at cost and is depreciated on the straight-line basis to its estimated residual value. Residual values are reviewed regularly and adjusted if market conditions warrant. Derivative Financial Instruments: As part of its risk management strategy, the Company enters into derivative contracts to hedge against interest-rate 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 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 $4.1 at December 31, 2018. The Company uses regression analysis to assess effectiveness of interest-rate contracts at inception and uses quantitative or qualitative analysis to assess subsequent effectiveness on a quarterly basis. All components of the derivative instrument’s gain or loss are included in the assessment of hedge effectiveness. Hedge accounting is discontinued prospectively when the Company determines that a derivative financial instrument has ceased to be a highly effective hedge. Cash flows from derivative instruments are included in operating activities in the Statements of Cash Flows. Income Taxes The Company is included in the consolidated federal income tax return of PACCAR. Federal income taxes for the Company are determined on a separate return basis, and any related tax liability is paid by the Company to PACCAR and any related tax benefit is paid by PACCAR to the Company. State income taxes, where the Company files combined tax returns with PACCAR, are determined on a blended statutory rate, which is substantially the same as the rate computed on a separate return basis. As of December 31, 2018, the United States Internal Revenue Service has completed examinations of PACCAR’s tax returns for all years through 2014. PACCAR’s tax returns remain subject to examination in other jurisdictions for the years ranging from 2013 through 2018. Preferred Stock The Company’s Articles of Incorporation provide that the 6%, noncumulative, nonvoting preferred stock (100% owned by PACCAR) is redeemable only at the option of the Company’s Board of Directors. New Accounting Pronouncements: In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-13 , Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) The Company will elect the package of practical expedients for its leases existing prior to the adoption of this ASU that will retain its conclusions about lease identification, lease classification and initial direct costs. Upon adoption, the Company will elect the short-term lease exemption to not recognize right-of-use assets and lease liabilities for any leases with a duration of twelve months or less. The Company does not expect the adoption of this ASU to have a material impact on the Balance Sheets and the Statements of Income. ASU 2016-02 requires lessors to classify cash receipts from leases within operating activities. As required by the new standard, the Company will present cash receipts from direct financing leases as an operating cash inflow rather than the current presentation as an investing cash inflow. For the year ended December 31, 2018 total cash receipts from direct financing leases was $428.3 million. On December 19, 2018, the FASB issued a proposed ASU – Leases (Topic 842): Codification Improvements for Lessors Financial Services – Depository and Lending The Company adopted the following standards effective January 1, 2018, which did not have a material impact on the Company’s financial statements.

Experience indicates substantially all of dealer wholesale financing will be repaid within one year. In addition, collection experience indicates that some loans, leases and other finance receivables will be paid prior to contract maturity, while others may be extended or modified. 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 Company’s portfolio assets are diversified over a large number of customers and dealers with no single customer or dealer balances representing over 10% of the total portfolio assets as of December 31, 2018 and 2017. The Company has contractual arrangements with one customer, Swift Transportation Company, that accounted for 5.9%, 10.4% and 12.1% of total Interest and other revenues for the years ended December 31, 2018, 2017 and 2016, respectively. 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. 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 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 Year ended December 31 2018 2017 Fleet $ 4.3 Owner/Operator $ 4.3 There were no finance receivables modified as TDRs during the last twelve months that subsequently defaulted in 2018. There were nil and $1.4 of finance receivables modified as TDRs during the previous twelve months that subsequently defaulted and were charged off in 2018 and 2017, 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 loans, finance leases and equipment under operating leases. The Company records the vehicles as used truck inventory included in Other assets on the Balance Sheets. The balance of repossessed units at December 31, 2018 and 2017 was $1.6 and $7.5, respectively. Proceeds from the sales of repossessed assets were $18.8, $28.2 and $21.5 for the years ended December 31, 2018, 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 under operating leases are recorded as impairments and included in Depreciation and other rental expenses on the Statements of Income.

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 December 31, 2018, the notional amount of these contracts totaled $1,074.0 with amounts expiring over the next ten years. Notional maturities for all interest-rate contracts are $243.0 for 2019, $190.0 for 2020, $327.1 for 2021, $201.3 for 2022, $31.5 for 2023 and $81.1 thereafter The following table presents the balance sheet classification, fair value and gross and net amounts of derivative financial instruments: As of December 31 2018 2017 Interest-rate contracts: Assets Liabilities Assets Liabilities Other assets $ 4.1 $ 3.1 Accounts payable, accrued expenses and other $ 5.3 $ 2.7 Gross amounts recognized in Balance Sheets 4.1 5.3 3.1 2.7 Less amounts not offset in financial instruments (2.4 ) (2.4 ) (.5 ) (.5 ) Pro-forma net amount $ 1.7 $ 2.9 $ 2.6 $ 2.2 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. 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 and are presented in the same income statement line as the earnings effect of the hedged transaction. The amount of gain recorded in AOCI at December 31, 2018 that is estimated to be reclassified to interest expense in the following 12 months if interest rates remain unchanged is approximately $1.1, 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. As of December 31, 2018, the following amounts were recorded on the Balance Sheets related to cumulative basis adjustments for fair value hedges: Cumulative Basis Amount Carrying Amount of Included in the Hedged Balance Sheet Line Item the Hedged Liabilities Carrying Amount Medium-term notes $ 188.7 $ (1.3 ) The above table excludes the cumulative basis adjustments on discontinued hedge relationships of $(2.9) as of December 31, 2018.

Income Taxes	NOTE I – INCOME TAXES The Company’s effective income tax rate was a provision of 23.4% for 2018 compared to a benefit of (328.5)% for 2017. The primary difference in tax rates was due to the change in U.S. tax law in 2017 as further explained below. The components of the Company’s provision for income taxes include the following: Year ended December 31 2018 2017 2016 Current (benefit) provision Federal $ (8.1 ) $ (95.9 ) $ 19.2 State .2 4.0 .9 (7.9 ) (91.9 ) 20.1 Deferred provision (benefit) Federal 33.5 (214.2 ) 28.7 State 2.7 6.2 1.5 36.2 (208.0 ) 30.2 Total provision (benefit) for income taxes $ 28.3 $ (299.9 ) $ 50.3 A reconciliation of the statutory U.S. federal tax rate to the effective income tax rate is as follows: Year ended December 31 2018 2017 2016 Statutory rate 21.0 % 35.0 % 35.0 % Effect of: Rate change on U.S. federal deferred taxes (370.8 )% State 2.4 % 7.3 % 1.1 % 23.4 % (328.5 )% 36.1 % Cash paid for income taxes was $4.1, $.1, and $1.5 in 2018, 2017 and 2016, respectively. On December 22, 2017, the U.S. enacted new federal income tax legislation, the Tax Cuts and Jobs Act (“the Tax Act”). The Tax Act lowered the U.S. statutory income tax rate from 35.0% to 21.0%. The Company recorded a provisional amount of $338.5 of deferred tax benefits due to the re-measurement of net deferred tax liabilities at the new lower statutory tax rate. As of December 31, 2018, the Company has concluded that no further adjustments for the provisional amounts recorded under Staff The tax effects of temporary differences representing deferred tax assets and liabilities are as follows: December 31 December 31 2018 2017 Deferred tax assets: Allowance for losses on receivables $ 14.8 $ 14.4 Other 9.0 11.1 Deferred tax liabilities: Depreciation (656.5 ) (621.5 ) Derivative asset (.9 ) (1.9 ) Net deferred tax liability $ (633.6 ) $ (597.9 )

Fair Value Measurements

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 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 year ended December 31, 2018. 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: December 31 December 31 Level 2 2018 2017 Assets: Impaired loans, net of specific reserves (2018 - $.6 and 2017 - $1.8) $ 2.5 $ 8.4 Used trucks held for sale 40.5 53.3 Derivative contracts 4.1 3.1 Liabilities: Derivative contracts $ 5.3 $ 2.7 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 sold individually, which is the lowest unit of account, and the condition of the vehicles. Used truck impairments related to units held at December 31, 2018 and 2017 were $11.5 and $23.0 during 2018 and 2017, 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 assumptions regarding credit and liquidity risks to approximate 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: December 31 December 31 2018 2017 Carrying Fair Carrying Fair Amount Value Amount Value Assets: Due from PACCAR $ 821.0 $ 815.2 $ 765.5 $ 762.5 Due from foreign finance affiliates 472.0 474.2 172.0 172.0 Fixed rate loans 3,239.5 3,234.4 2,756.9 2,758.4 Liabilities: Fixed rate debt $ 4,394.4 $ 4,363.2 $ 4,091.8 $ 4,072.0

Accounting Policies [Abstract]
Description of Operations and Basis of Presentation	Description of Operations and Basis of Presentation PACCAR Financial Corp. (the “Company”), is a wholly owned subsidiary of PACCAR Inc (“PACCAR”). The Company primarily provides financing of PACCAR manufactured trucks and related equipment sold by authorized dealers. The Company also finances dealer inventories of transportation equipment and franchises Kenworth and Peterbilt dealerships to engage in full-service and finance leasing. The operations of the Company are fundamentally affected by its relationship with PACCAR. Due to the nature of the Company’s business, customers are concentrated in the transportation industry throughout the United States. Generally, all receivables are collateralized by the equipment being financed. The risk of credit losses related to this concentration has been considered in establishing the allowance for credit losses.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.
Finance and Other Receivables	Finance and Other Receivables: Loans – Loans represent fixed or floating rate loans to customers or dealers collateralized by the vehicles purchased and are recorded at amortized cost. Finance leases – Finance leases are retail direct financing leases and sales-type finance leases, which lease equipment to retail customers and dealers. These leases are reported as the sum of minimum lease payments receivable and estimated residual value of the property subject to the contracts, reduced by unearned interest which is shown separately. Dealer wholesale financing – Dealer wholesale financing is floating-rate wholesale loans to Kenworth and Peterbilt dealers for new and used trucks and are recorded at amortized cost. The loans are collateralized by the trucks being financed. Operating lease receivables – Operating lease receivables and other include monthly rentals due on operating leases, unamortized loan and lease origination costs, interest on loans and other amounts due within one year in the normal course of business.
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 considered TDRs. On average, modifications extended contractual terms by approximately four months in 2018 and three months in 2017 and did not have a significant effect on the weighted average term or interest rate of the total portfolio at December 31, 2018 or 2017. 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.
Revenue Recognition	Revenue Recognition Interest income from finance and other receivables is recognized using the interest method. Certain loan and lease origination costs are deferred and amortized to interest income over the expected life of the contracts, generally 36 to 60 months, using the straight-line method which approximates the interest method. For operating leases, rental revenue is recognized on a straight-line basis over the lease term. 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 December 31, 2018 or December 31, 2017. 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. The Company recognizes revenue on the sale of used trucks acquired from PACCAR truck division customers as part of new truck sales packages when the used trucks are invoiced and delivered to a customer.
Equipment on Operating Leases	Equipment on Operating Leases Equipment on operating leases is recorded at cost and is depreciated on the straight-line basis to its estimated residual value. Residual values are reviewed regularly and adjusted if market conditions warrant.
Derivative Financial Instruments	Derivative Financial Instruments: As part of its risk management strategy, the Company enters into derivative contracts to hedge against interest-rate 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 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 $4.1 at December 31, 2018. The Company uses regression analysis to assess effectiveness of interest-rate contracts at inception and uses quantitative or qualitative analysis to assess subsequent effectiveness on a quarterly basis. All components of the derivative instrument’s gain or loss are included in the assessment of hedge effectiveness. Hedge accounting is discontinued prospectively when the Company determines that a derivative financial instrument has ceased to be a highly effective hedge. Cash flows from derivative instruments are included in operating activities in the Statements of Cash Flows.
Income Taxes	Income Taxes The Company is included in the consolidated federal income tax return of PACCAR. Federal income taxes for the Company are determined on a separate return basis, and any related tax liability is paid by the Company to PACCAR and any related tax benefit is paid by PACCAR to the Company. State income taxes, where the Company files combined tax returns with PACCAR, are determined on a blended statutory rate, which is substantially the same as the rate computed on a separate return basis. As of December 31, 2018, the United States Internal Revenue Service has completed examinations of PACCAR’s tax returns for all years through 2014. PACCAR’s tax returns remain subject to examination in other jurisdictions for the years ranging from 2013 through 2018.
Preferred Stock	Preferred Stock The Company’s Articles of Incorporation provide that the 6%, noncumulative, nonvoting preferred stock (100% owned by PACCAR) is redeemable only at the option of the Company’s Board of Directors.
New Accounting Pronouncements	New Accounting Pronouncements: In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-13 , Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) The Company will elect the package of practical expedients for its leases existing prior to the adoption of this ASU that will retain its conclusions about lease identification, lease classification and initial direct costs. Upon adoption, the Company will elect the short-term lease exemption to not recognize right-of-use assets and lease liabilities for any leases with a duration of twelve months or less. The Company does not expect the adoption of this ASU to have a material impact on the Balance Sheets and the Statements of Income. ASU 2016-02 requires lessors to classify cash receipts from leases within operating activities. As required by the new standard, the Company will present cash receipts from direct financing leases as an operating cash inflow rather than the current presentation as an investing cash inflow. For the year ended December 31, 2018 total cash receipts from direct financing leases was $428.3 million. On December 19, 2018, the FASB issued a proposed ASU – Leases (Topic 842): Codification Improvements for Lessors Financial Services – Depository and Lending The Company adopted the following standards effective January 1, 2018, which did not have a material impact on the Company’s financial statements.
