New Accounting Pronouncements

New Revenue Standard

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers, including subsequently issued ASUs to clarify the implementation guidance in ASU 2014-09. Under the new revenue recognition model, a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The Company adopted this ASU for outstanding contracts on a modified retrospective basis on January 1, 2018.

The most significant effect of the standard relates to certain trucks sold in Europe that are subject to a residual value guarantee (RVG) and were accounted for as an operating lease in the Truck, Parts and Other section of the Company’s Consolidated Balance Sheets. Prior to the adoption of ASU 2014-09, these sales were recognized on a straight-line basis over the guarantee period. Under the new standard, revenues are recognized upon transfer of control for certain of these RVG contracts that allow customers the option to return their truck and for which there is no economic incentive to do so. The estimate of customers’ economic incentive to return the truck is based on an analysis of historical guaranteed buyback value and estimated market value. A return asset and liability is recognized for estimated returns. Return rates are estimated by using a historical weighted average return rate over a four-year period. Also as required by the new standard, the Company recognized an asset for the value of expected returned aftermarket parts which had previously been netted with the related liabilities.

The cumulative effect of the changes made to the Company’s Consolidated Balance Sheet on January 1, 2018 for the adoption of ASU 2014-09 was as follows:

New Pension Standard

In March 2017, FASB issued ASU 2017-07 Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The amendment disaggregates the service cost component from non-service cost components of pension expense and prescribes where to present the various components of pension cost on the income statement. This ASU also allows only the service cost component to be eligible for capitalization, when applicable (e.g. as a cost of manufactured inventory or self-constructed assets). The Company adopted this ASU in January 2018 and accordingly applied the income statement presentation of service and non-service components of pension expense retrospectively and the capitalization of service cost prospectively. Adoption of this ASU had no impact on net income. The retrospective application of this ASU had the following effects on the Consolidated Statement of Comprehensive Income:

Other Standards

In February 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2018-02 Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The amendment requires a reclassification from accumulated other comprehensive income (AOCI) to retained earnings the difference between the historical corporate income tax rate and the newly enacted income tax rate resulting from the Tax Act. This ASU is effective for annual periods beginning after December 15, 2018, and interim periods within those annual periods and early adoption is permitted. Upon adoption, the Company estimates Retained earnings will increase and AOCI will decrease approximately $30 million with no impact to Stockholders’ Equity. The Company expects to early adopt this ASU in the fourth quarter of 2018.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The amendment in this ASU requires entities having financial assets measured at amortized cost to estimate credit reserves under an expected credit loss model rather than the current incurred loss model. Under this new model, expected credit losses will be based on relevant information about past events, including historical experience, current conditions and reasonable and supportable forecasts that affect collectability. The ASU is effective for annual periods beginning after December 15, 2019 and interim periods within those annual periods. Early adoption is permitted, but not earlier than annual and interim periods beginning after December 15, 2018. This amendment should be applied on a modified retrospective basis with a cumulative effect adjustment to retained earnings as of the beginning of the period of adoption. The Company is currently evaluating the impact on its financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) which amends the existing accounting standards for leases. Under the new lease standard, lessees will recognize a right-of-use asset and a lease liability for virtually all leases (other than short-term leases). Lessor accounting is largely unchanged. The ASU is effective for annual periods beginning after December 15, 2018 and interim periods within those annual periods. Early adoption is permitted. This ASU requires leases to be recognized and measured at the beginning of the earliest period presented using a modified retrospective approach with optional practical expedients. The Company is currently evaluating the impact on its consolidated financial statements.

In addition to adopting the ASUs discussed above, the Company adopted the following standards effective January 1, 2018, none of which had a material impact on the Company’s consolidated financial statements.  

STANDARD	DESCRIPTION
2016-01 *	Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.
2016-15 *	Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments.
2017-12 **	Derivative and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities.

* The Company adopted on the effective date of January 1, 2018.

** The Company early adopted in 2018.

NOTE B – Sales and Revenues

The Company enters into sales contracts with customers associated with purchases of the Company’s products and services including trucks, parts, product support, and other related services. Generally, the Company recognizes revenue for the amount of consideration it will receive for delivering a product or service to a customer. Revenue is recognized when the customer obtains control of the product or receives benefits of the service. The Company excludes sales taxes, value added taxes and other related taxes assessed by government agencies from revenue. There are no significant financing components included in product or services revenue since, generally customers pay shortly after the products or services are transferred. In the Truck and Parts segment, when the Company grants extended payment terms on selected receivables and charges interest, interest income is recognized when earned.

The following table disaggregates Truck, Parts and Other revenues by major sources:  

	Three Months Ended
	March 31, 2018
Truck
Truck sales	$	4,174.4
Revenues from extended warranties, operating leases and other		178.6
		4,353.0
Parts
Parts sales	912.1
Revenues from dealer services and other		27.8
		939.9
Winch sales and other	28.9
Truck, Parts and Other sales and revenues	$	5,321.8

The Company recognizes truck and parts sales as revenue when control of the products is transferred to customers, except for certain truck sales which are subject to a residual value guarantee by the Company. The standard payment term for trucks and aftermarket parts is typically within 30 days, but the Company may grant extended payment terms on selected receivables. The Company recognizes revenue for the invoice amount adjusted for estimated sales incentives and returns. Sales incentives and returns are estimated based on historical experience and are adjusted to current period revenue when the most likely amount of consideration the Company expects to receive changes or becomes fixed.  Truck and part sales include a standard product warranty which is included in cost of sales. The Company has elected to treat delivery services as a fulfilment activity with revenues recognized when the customer obtains control of the product. Delivery revenue is included in revenues and the related costs are included in cost of sales. As a practical expedient, the Company is not disclosing truck order backlog, as a significant majority of the backlog has a duration of less than one year.

Truck sales with RVGs that allow customers the option to return their truck are accounted for as a sale when the customer does not have an economic incentive to return the truck to the Company, or as an operating lease when the customer does have an economic incentive to return the truck. The estimate of customers’ economic incentive to return the trucks is based on an analysis of historical guaranteed buyback value and estimated market value. When truck sales with RVGs are accounted for as a sale, revenue is recognized when the truck is transferred to the customer less an amount for expected returns. Expected return rates are estimated by using a historical weighted average return rate over a four-year period. The estimated value of the returned truck assets and the related return liabilities at March 31, 2018 were $199.9 and $208.8, respectively.  

Revenues from extended warranties, operating leases and other includes optional extended warranty and repair and maintenance service contracts which can be purchased for periods generally ranging up to five years. The Company defers revenue based on stand-alone observable selling prices when it receives payments in advance and recognizes the revenue on a straight-line basis over the warranty or repair and maintenance contract periods. See Footnote F, Product Support Liabilities, in the Notes to the Consolidated Financial Statements for further information. Also included are truck sales with an RVG accounted for as an operating lease. A liability is created for the residual value obligation with the remainder of the proceeds recorded as deferred revenue. The deferred revenue is recognized on a straight-line basis over the guarantee period, which typically ranges from three to five years. Deferred revenue related to trucks sold with a residual value guarantee was $686.8 at March 31, 2018. The Company expects to recognize approximately $149.2 of the remaining deferred revenue in 2018, $236.5 in 2019, $198.3 in 2020, $64.2 in 2021, $35.5 in 2022 and $3.1 thereafter.

Aftermarket parts sales allow for returns which are estimated at the time of sale based on historical data. The estimated value of the returned goods asset was $44.1 and the related return liability was $91.2 at March 31, 2018. The Company increased parts sales by

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

$2.3 in the first quarter of 2018 due to changes in the reserve balance. Parts dealer services and other revenues are recognized as services are performed.

Revenue from winch sales and other is primarily derived from the industrial winch business. Winch sales are recognized when the product is transferred to a customer. Also within this category are other revenues not attributable to a reportable segment.

NOTE C - Investments in Marketable Debt Securities

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

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

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

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

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

Marketable debt securities at March 31, 2018 and December 31, 2017 consisted of the following:

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 $.9 and $.5 and gross realized losses were $.5 and $.2 for the three month periods ended March 31, 2018 and 2017, respectively.

Marketable debt securities with continuous unrealized losses and their related fair values were as follows:

	March 31, 2018				December 31, 2017
	LESS THAN		TWELVE MONTHS		LESS THAN		TWELVE MONTHS
	TWELVE MONTHS		OR GREATER		TWELVE MONTHS		OR GREATER
Fair value	$	841.6	$	22.7	$	908.5	$	18.4
Unrealized losses		6.1		.3		4.8		.2

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, 2018were as follows:

	AMORTIZED		FAIR
Maturities:	COST		VALUE
Within one year	$	333.7	$	333.2
One to five years		694.1		688.9
More than ten years		24.4		24.4
	$	1,052.2	$	1,046.5

NOTE D - Inventories

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

Inventories include the following:

	March 31			December 31
	2018			2017
Finished products	$	602.5		$	515.7
Work in process and raw materials		641.1			586.2
		1,243.6			1,101.9
Less LIFO reserve		(175.3	)		(173.5	)
	$	1,068.3		$	928.4

Under the LIFO method of accounting (used for approximately 44% of March 31, 2018 inventories), an actual valuation can be made only at the end of each year based on year-end inventory levels and costs. Accordingly, interim valuations are based on management’s estimates of those year-end amounts.

	$	10,103.9		$	9,697.1

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 March 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.

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 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 2018 and five months in 2017 and did not have a significant effect on the weighted average term or interest rate of the total portfolio at March 31, 2018 and December 31, 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 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

- 13 -

PACCAR Inc – Form 10-Q

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

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 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 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 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.

Credit Quality

The Company's customers are principally concentrated in the transportation industry in North America, Europe and Australia. The Company’s portfolio assets are diversified over a large number of customers and dealers with no single customer or dealer balances representing over 5% of the total portfolio assets. 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 tables below summarize the Company’s finance receivables by credit quality indicator and portfolio class.

There were $1.8 and $5.1 of finance receivables modified as TDRs during the previous twelve months that subsequently defaulted and were charged off in the three months ended March 31, 2018 and 2017, respectively.

Repossessions

When the Company determines 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 leases. The Company records the vehicles as used truck inventory included in Financial Services Other assets on the Consolidated Balance Sheets. The balance of repossessed inventory at March 31, 2018 and December 31, 2017 was $13.9 and $13.1, respectively. Proceeds from the sales of repossessed assets were $8.5 and $15.5 for the three months ended March 31, 2018 and 2017, respectively. These amounts are included in Proceeds from asset disposals in the Condensed Consolidated Statements of Cash Flows. Write-downs of repossessed equipment on operating leases are recorded as impairments and included in Financial Services Depreciation and other expenses on the Consolidated Statements of Comprehensive Income.

NOTE F - 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.

Changes in product support liabilities are summarized as follows:

WARRANTY RESERVES	2018			2017
Balance at January 1	$	298.8		$	282.1
Cost accruals		74.6			51.3
Payments		(68.8	)		(59.1	)
Change in estimates for pre-existing warranties		10.8			3.7

Revenues recognized		(93.4	)		(71.8	)
Currency translation		10.4			4.7
Balance at March 31	$	686.0		$	589.2

The Company expects to recognize approximately $162.2 of the remaining deferred revenue on extended warranties and R&M contracts in 2018, $225.8 in 2019, $164.1 in 2020, $79.9 in 2021, $37.0 in 2022 and $17.0 thereafter.

PACCAR Inc – Form 10-Q

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

During the first three months of 2018, the Company issued 314,244 common shares under deferred and stock compensation arrangements.

Other Capital Stock Changes

During the first quarter of 2018, the Company purchased 257,790 treasury shares, of which 248,934 shares were repurchased pursuant to the $300 million common stock repurchase plan approved on September 23, 2015. The Company also acquired 8,856 shares under the Company’s Long-Term Incentive Plan.

NOTE H - Income Taxes

The effective tax rate for the first quarter of 2018 was 23.5% compared to 30.8% in the first quarter of 2017. The difference in tax rates was primarily due to the U.S. federal income tax legislation enacted on December 22, 2017, which lowered the U.S. statutory income tax rate from 35.0% to 21.0%.

NOTE I - 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 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 for the year ended December 31, 2017.

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.

NOTE J - 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 derivatives not designated as hedging instruments. 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 $45.7 at March 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. 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. 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 Consolidated Statements of Cash Flows.

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

At March 31, 2018, the notional amount of the Company’s interest-rate contracts was $3,155.6. Notional maturities for all interest-rate contracts are $906.7 for the remainder of 2018, $934.1 for 2019, $450.2 for 2020, $634.4 for 2021, $141.8 for 2022, $15.8 for 2023 and $72.6 thereafter.

Foreign-Exchange Contracts:The Company enters into foreign-exchange contracts to hedge certain anticipated transactions and assets and liabilities denominated in foreign currencies, particularly the Canadian dollar, the euro, the British pound, the Australian dollar, the Brazilian real and the Mexican peso. The objective is to reduce fluctuations in earnings and cash flows associated with changes in foreign currency exchange rates. At March 31, 2018, the notional amount of the outstanding foreign-exchange contracts was $523.7. Foreign-exchange contracts mature within one year.

Fair Value Hedges  

Changes in the fair value of derivatives designated as fair value hedges are recorded in earnings together with the changes in fair value of the hedged item attributable to the risk being hedged. As of March 31, 2018, the following amounts were recorded on the Consolidated Balance Sheets related to cumulative basis adjustments for fair value hedges:

			Cumulative Basis
	Carrying Amount of		Amount Included in
Hedged Balance Sheet Line Item	the Hedged Liabilities		the Carrying Amount
Medium-term notes	$	280.5	$	(4.5	)

The above table excludes the cumulative basis adjustments on discontinued hedge relationships of ($2.4) million as of March 31, 2018.

Cash Flow Hedges

Substantially all of the Company’s interest-rate contracts and some foreign-exchange contracts have been designated as cash flow hedges. 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. Changes in the fair value of derivatives designated as cash flow hedges are recorded in AOCI. 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 9.9 years.

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

The amount of gain recorded in AOCI at March 31, 2018 that is estimated to be reclassified into earnings in the following 12 months if interest rates and exchange rates remain unchanged is approximately $2.6, net of taxes.

Derivatives Not Designated As Hedging Instruments

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 derivatives not designated as hedging instruments are recorded in earnings in the period in which the change occurs.

For the quarters ended March 31, 2018 and 2017, the 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,	2018		2017
Truck, Parts and Other:
Cost of sales and revenues	$	1.2	$	3.3

NOTE K - 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 themeasurement 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, 2018. The Company’s policy is to recognize transfers between levels at the end of the reporting period.

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

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

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

Derivative Financial Instruments: The Company’s derivative contracts consist of interest-rate swaps, cross currency swaps and foreign currency exchange contracts. These derivative contracts are traded over the counter, and their fair value is determined using industry standard valuation models, which are based on the income approach (i.e. discounted cash flows). The significant observable

- 25 -

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

inputs into the valuation models include interest rates, yield curves, currency exchange rates, credit default swap spreads and forward rates and are categorized as Level 2.

Assets and Liabilities Subject to Recurring Fair Value Measurement

Fair Value Disclosure of Other Financial Instruments

For financial instruments that are not recognized at fair value, the Company uses the following methods and assumptions to determine the fair value. These instruments are categorized as Level 2, except cash which is categorized as Level 1 and fixed rate loans which are categorized as Level 3.

Cash and Cash Equivalents: Carrying amounts approximate fair value.

Financial Services Net Receivables: For floating-rate loans, wholesale financings, and 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 the credit and market risks to approximate current rates for comparable loans. Finance lease receivables and related allowance for credit losses have been excluded from the accompanying table.

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

The Company’s estimate of fair value for fixed rate loans and debt that are not carried at fair value was as follows:

	March 31, 2018				December 31, 2017
	CARRYING		FAIR		CARRYING		FAIR
	AMOUNT		VALUE		AMOUNT		VALUE
Assets:
Financial Services fixed rate loans	$	3,919.4	$	3,882.7	$	3,793.8	$	3,804.8
Liabilities:
Financial Services fixed rate debt		5,349.5		5,307.3		5,397.6		5,387.0

NOTE L - 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,	2018			2017
Service cost	$	28.7		$	23.8
Interest on projected benefit obligation		21.3			20.4
Expected return on assets		(44.8	)		(39.8	)
Amortization of prior service costs		.4			.3
Recognized actuarial loss		7.7			6.7
Net pension expense	$	13.3		$	11.4

The components of net pension expense other than service cost are included in Interest and other (income), net on the Consolidated Statements of Comprehensive Income.

During the three months ended March 31, 2018 and 2017, the Company contributed $75.6 and $4.9 to its pension plans, respectively.

NOTE M – Commitments and Contingencies

On July 19, 2016, the European Commission (EC) concluded its investigation of all major European truck manufacturers and reached a settlement with DAF. Following the settlement, claims and lawsuits have been filed against the Company, DAF and certain DAF subsidiaries and other truck manufacturers. Others may bring EC related claims and lawsuits against the Company or its subsidiaries. While the Company believes it has meritorious defenses, such claims and lawsuits will likely take a significant period of time to resolve. An adverse outcome of such proceedings could have a material impact on the Company’s results of operations.    

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

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

OVERVIEW:

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

First Quarter Highlights:

• Worldwide net sales and revenues were a quarterly record $5.65 billion in 2018 compared to $4.24 billion in 2017.

• Truck sales were a record $4.35 billion in 2018 compared to $3.13 billion in 2017, primarily due to higher truck deliveries in the U.S. and Canada, Europe and Australia, and favorable currency translation effects.

• Parts sales were a record $939.9 million in 2018 compared to $786.7 million in 2017, reflecting higher demand in all markets.

• Financial Services revenues were $332.2 million in 2018 compared to $302.2 million in 2017. The increase was primarily the result of higher average earning asset balances and favorable currency translation effects.  

• Net income was $512.1 million ($1.45 per diluted share) in 2018 compared to $310.3 million ($.88 per diluted share) in 2017. The operating results reflect record Truck and Parts segment revenues, improved Financial Services results, and favorable currency translation effects. In addition, net income increased in the first quarter due to a lower effective tax rate (23.5% in 2018 as compared to 30.8% in 2017) associated with the new U.S. tax law.

• Capital investments were $66.8 million in 2018 compared to $72.7 million in 2017.

• Research and development (R&D) expenses were $76.0 million in 2018 compared to $61.0 million in 2017.

Peterbilt launched its new Model 579 UltraLoft, which offers customers a high-roof, integrated cab and sleeper that enhances driver comfort and operational efficiency. The UltraLoft dimensions represent an 18 percent increase in interior space giving drivers best-in-class living quarters. The Model 579 UltraLoft is an excellent tractor for long-haul routes, team driving, and driver training.

The PACCAR Financial Services (PFS) group of companies has operations covering four continents and 24 countries. The global breadth of PFS and its rigorous credit application process support a portfolio of loans and leases with record total assets of $13.59 billion. PFS issued $400 million in medium-term notes during the first three months of 2018 to support portfolio growth.

Truck Outlook

Truck industry retail sales in the U.S. and Canada in 2018 are expected to be 265,000 to 285,000 units compared to 218,400 in 2017. In Europe, the 2018 truck industry registrations for over 16-tonne vehicles are expected to be 300,000 to 320,000 units compared to 306,100 truck registrations in 2017. In South America, heavy-duty truck industry sales in 2018 are estimated to be in a range of 70,000 to 80,000 units compared to 68,600 in 2017.

Parts Outlook

In 2018, PACCAR Parts sales are expected to grow 10-12% compared to 2017 sales.

Financial Services Outlook

Based on the truck market outlook, average earning assets in 2018 are expected to increase 6-8% compared to 2017. Current strong levels of freight tonnage, freight rates and fleet utilization are contributing to customers’ profitability and cash flow. If current freight transportation conditions decline due to weaker economic conditions, then past due accounts, truck repossessions and credit losses would likely increase from the current low levels and new business volume would likely decline.

DAF market share in the 6 to 16-tonne market in the first quarter of 2018 was 9.7% compared to 11.8% in the same period of 2017. DAF deliveries in 2018 also reflect higher deliveries to non-EU Europe.

The Company’s worldwide truck net sales and revenues are summarized below:  

($ in millions)
Three Months Ended March 31,	2018			2017			% CHANGE
Truck net sales and revenues:
U.S. and Canada	$	2,614.7		$	1,804.6			45

The major factors for the changes in net sales and revenues, cost of sales and revenues and gross margin between the three months ended March 31, 2018 and 2017 for the Truck segment are as follows:

	NET			COST OF
	SALES AND			SALES AND			GROSS
($ in millions)	REVENUES			REVENUES			MARGIN
Three Months Ended March 31, 2017	$	3,130.1		$	2,803.9		$	326.2

Three Months Ended March 31, 2018	$	4,353.0		$	3,835.6		$	517.4

• Truck sales volume primarily reflects higher unit deliveries in the U.S. and Canada ($746.1 million sales and $608.1 million cost of sales).

• Average truck sales prices increased sales by $59.9 million, primarily due to higher price realization in the U.S. and Canada ($51.5 million).

• Average cost per truck increased cost of sales by $38.9 million, reflecting higher material costs.

• Factory overhead and other indirect costs increased $25.6 million, primarily due to higher salaries and related expenses ($11.4 million) and higher maintenance costs ($10.7 million).

• Extended warranties, operating leases and other decreased revenues by $9.7 million and cost of sales by $10.0 million primarily due to lower revenue recognized from operating leases.

• The currency translation effect on sales and cost of sales primarily reflects an increase in the value of the euro relative to the U.S. dollar.

• Truck gross margin was 11.9% in the first quarter of 2018 compared to 10.4% in the same period of 2017 due to the factors noted above.

Truck SG&A in the first quarter of 2018 increased to $63.2 million from $53.2 million in the first quarter of 2017. The increase was primarily due to the currency translation effects ($4.2 million) and higher professional fees ($4.0 million). As a percentage of sales, Truck SG&A decreased to 1.5% in the first quarter of 2018 from 1.7% in the first quarter of 2017, reflecting the higher sales volume.

Parts

The Company’s Parts segment accounted for 17% of revenues in the first quarter of 2018 compared to 19% in the first quarter of 2017.

The Company’s worldwide parts net sales and revenues for the first quarter increased to a record $939.9 million in 2018 from $786.7 million in 2017, primarily due to higher aftermarket demand and successful marketing programs in all markets, as well as favorable currency translation effects.

The increase in Parts segment income before income taxes and pre-tax return on revenues was primarily due to higher sales volume and favorable currency translation effects.

• Aftermarket parts sales volume increased by $97.0 million and related cost of sales increased by $62.7 million due to higher demand in all markets.

• Average aftermarket parts sales prices increased sales by $22.4 million, primarily due to higher price realization in the U.S. and Canada.

• Average aftermarket parts direct costs increased $16.6 million due to higher material costs.

• Warehouse and other indirect costs increased $5.0 million, primarily due to higher salaries and related expenses and higher maintenance costs.

• The currency translation effect on sales and cost of sales reflects an increase in the value of the euro relative to the U.S. dollar.

• Parts gross margins in the first quarter of 2018 increased to 27.9% from 27.4% in the first quarter of 2017 due to the factors noted above.

New loan and lease volume was $1,100.7 million in the first quarter of 2018 compared to $801.2 million in the first quarter of 2017, reflecting higher truck deliveries in all markets. In the first quarter of 2018, PFS finance market share on new PACCAR truck sales was 22.0% compared to 23.7% in the first quarter of 2017.

In the first quarter of 2018, PFS revenues increased to $332.2 million from $302.2 million in the first quarter of 2017. The increase was primarily due to revenue on higher average earning assets and the effects of translating stronger foreign currencies to the U.S. dollar. The effects of currency translation increased PFS revenues by $15.5 million in the first quarter of 2018.

PFS income before income taxes increased to $67.5 million for the first quarter of 2018 from $56.8 million in the first quarter of 2017, primarily due to higher average earning asset balances, higher results on returned lease assets and the effects of translating stronger foreign currencies to the U.S. dollar, partially offset by higher borrowing rates. The currency exchange impact increased PFS income before income taxes by $3.0 million for the first quarter of 2018.

Included in Financial Services “Other Assets” on the Company’s Consolidated Balance Sheets are used trucks held for sale, net of impairments, of $211.8 million at March 31, 2018 and $221.7 million at December 31, 2017. These trucks are primarily units returned from matured operating leases in the ordinary course of business, and also includes trucks acquired from repossessions or through acquisitions of used trucks in trades related to new truck sales.

In the first quarter, the Company recognized losses on used trucks, excluding repossessions, of $9.5 million in 2018 and $13.8 million in 2017, including losses on multiple unit transactions of $6.7 million in 2018 compared to $8.6 million in 2017. Used truck losses related to repossessions, which are recognized as credit losses, were not significant for the first quarters of 2018 and 2017.

The major factors for the changes in interest and fees, interest and other borrowing expenses and finance margin between the three months ended March 31, 2018 and 2017 are outlined below:

($ in millions)	INTEREST AND FEES		INTEREST AND OTHER BORROWING EXPENSES		FINANCE MARGIN
Three Months Ended March 31, 2017	$	102.2	$	34.1	$	68.1

Total increase		13.5		7.2		6.3
Three Months Ended March 31, 2018	$	115.7	$	41.3	$	74.4

• Average finance receivables increased $549.9 million (excluding foreign exchange effects) in the first quarter of 2018 as a result of retail portfolio new business volume exceeding collections and higher dealer wholesale balances.

• Average debt balances increased $405.5 million (excluding foreign exchange effects) in the first quarter of 2018. The higher average debt balances reflect funding for a higher average earnings asset portfolio, which includes loans, finance leases, wholesale and equipment on operating lease.

• Higher portfolio yields (4.9% in 2018 compared to 4.8% in 2017) increased interest and fees by $2.3 million. The higher portfolio yields reflect higher lending volumes in North America which has higher market rates than Europe.

• Higher borrowing rates (1.8% in 2018 compared to 1.6% in 2017) were primarily due to higher debt market rates in North America, partially offset by lower debt market rates in Europe.

• The currency translation effects reflect an increase in the value of foreign currencies relative to the U.S. dollar, primarily the euro and the Mexican Peso.

Total increase		16.5			6.7			9.8
Three Months Ended March 31, 2018	$	216.5		$	186.4		$	30.1

• A lower sales volume of used trucks received on trade decreased operating lease, rental and other revenues by $8.4 million. Depreciation and other expenses decreased by $7.9 million due to the lower sales volume of used trucks received on trade.

• Results on returned lease assets decreased depreciation and other expenses by $5.1 million, primarily due to lower losses on sales of returned lease units.

• Average operating lease assets increased $162.8 million (excluding foreign exchange effects), which increased revenues by $9.8 million and related depreciation and other expenses by $8.7 million.

• Revenue per asset increased $3.2 million primarily due to higher rental income and higher fee income. Cost per asset increased $2.0 million due to higher depreciation expense, partially offset by lower vehicle operating expenses.

• The currency translation effects reflect an increase in the value of foreign currencies relative to the U.S. dollar, primarily the euro and the Mexican Peso.

The following table summarizes the provision for losses on receivables and net charge-offs:

Three Months Ended March 31,	2018				2017

The provision for losses on receivables was $5.9million for the first quarter of 2018 and 2017, reflecting continued good portfolio performance.

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

The post-modification balance of accounts modified during the three months ended March 31, 2018 and 2017 are summarized below:

($ in millions)
Three Months Ended March 31,	2018					2017
	RECORDED INVESTMENT		% OF TOTAL PORTFOLIO*			RECORDED INVESTMENT		% OF TOTAL PORTFOLIO*

	$	100.3		5.0	%	$	119.7		6.6	%

* Recorded investment immediately after modification as a percentage of ending retail portfolio, on an annualized basis.

During the first quarter of 2018, total modification activity decreased compared to the first quarter of 2017, due to lower modifications for commercial reasons, insignificant delays and credit – TDRs, partially offset by higher credit – no concession modifications. The decrease in modifications for commercial reasons primarily reflects lower volumes of refinancing. The decrease in modifications for insignificant delay reflects fewer fleet customers requesting payment relief for up to three months. Credit – TDR modifications decreased to $.4 in 2018 from $8.9 in 2017 mainly due to contract modifications for two fleet customers in 2017. The increase in modifications for credit – no concession is primarily due to the contract modification of one fleet customer in Europe.

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

	March 31 2018			December 31 2017			March 31 2017
Percentage of retail loan and lease accounts 30+ days past due:
U.S. and Canada		.3	%		.4	%		.2	%
Europe		.6	%		.3	%		.6	%
Mexico, Australia and other		2.2	%		1.5	%		2.6	%
Worldwide		.6	%		.5	%		.6	%

Accounts 30+ days past due were .6% at March 31, 2018 compared to .5% at December 31, 2017, as higher past due accounts in Europe and Mexico were partially offset by lower past dues in the U.S. and Canada. The Company continues to focus on maintaining low past due balances.

When the Company modifies a 30+ days past due account, the customer is then generally considered current under the revised contractual terms. The Company modified $1.3 million of accounts worldwide during the first quarter of 2018, $.6 million during the fourth quarter of 2017 and $2.6 million during the first quarter of 2017 that were 30+ days past due and became current at the time of modification. Had these accounts not been modified and continued to not make payments, the pro forma percentage of retail loan and lease accounts 30+ days past due would have been as follows:

	March 31 2018			December 31 2017			March 31 2017
Pro forma percentage of retail loan and lease accounts 30+ days past due:
U.S. and Canada		.3	%		.4	%		.2	%
Europe		.6	%		.3	%		.6	%
Mexico, Australia and other		2.2	%		1.5	%		2.8	%
Worldwide		.6	%		.5	%		.7	%

Modifications of accounts in prior quarters that were more than 30 days past due at the time of modification are included in past dues if they were not performing under the modified terms at March 31, 2018, December 31, 2017 and March 31, 2017. The effect on the allowance for credit losses from such modifications was not significant at March 31, 2018, December 31, 2017 and March 31, 2017.

The Company’s annualized pre-tax return on average earning assets for Financial Services was 2.2% for the first quarter of 2018 compared to 2.0% for the same period in 2017.

Other

Other includes the winch business as well as sales, income and expenses not attributable to a reportable segment, including a portion of corporate expense. Other sales represent less than 1% of consolidated net sales and revenues for both the first quarter of 2018 and 2017. Other SG&A increased to $22.4 million for the first quarter of 2018 from $13.5 million for the first quarter of 2017, primarily due to higher compensation costs and higher professional fees.

For the first quarter, other income before tax was $4.9 million in 2018 compared to $1.3 million in 2017, primarily due to improved results in the Winch business.

Investment income for the first quarter increased to $10.0 million in 2018 from $8.1 million in 2017. The higher investment income in the first quarter of 2018 was primarily due to higher average portfolio balances and higher yields on U.S. investments due to higher market interest rates.

Income Taxes

The effective tax rate for the first quarter of 2018 was 23.5% compared to 30.8% for the first quarter of 2017. The difference in tax rates was primarily due to the U.S. federal income tax legislation enacted on December 22, 2017, which lowered the U.S. statutory income tax rate from 35.0% to 21.0%.

Total pre-tax return on revenues		11.8	%		10.6	%

For the first quarter of 2018, both domestic and foreign income before income taxes improved primarily due to higher revenues from truck, parts and finance operations. Domestic pre-tax return on revenues increased primarily due to improved truck and parts results.

Marketable debt securities		1,046.5		1,367.1

The Company’s total cash and marketable debt securities at March 31, 2018 decreased $181.2 million from the balances at December 31, 2017, primarily due to a decrease in marketable debt securities.

The change in cash and cash equivalents is summarized below:

Cash and cash equivalents at beginning of period		2,364.7			1,915.7

Operating activities:  Cash provided by operations decreased by $85.2 million to $525.3 million in the first quarter of 2018 from $610.5 million in 2017. Lower operating cash flows reflect a higher increase in Financial Services segment wholesale receivables of $152.2 million, a $100.7 million increase in net purchases of inventories, and a decrease of $97.0 million in other liabilities mainly related to income tax liabilities. In addition, there were decreased cash inflows of $75.0 million from accounts receivables as cash receipts were lower than sales in 2018, and higher cash usage for pension contributions of $70.7 million. The lower cash flows were partially offset by higher cash inflows of $253.7 million from accounts payable and accrued expenses as purchases of goods and services exceeded payments and higher net income of $201.8 million.  

Investing activities:  Cash used in investing activities decreased by $280.9 million to $56.1 million in the first quarter of 2018 from $337.0 million in 2017. Lower net cash used in investing activities reflects $320.1 million in net proceeds of marketable debt securities in 2018 compared to $60.3 million in net purchases of marketable debt securities in 2017. The decrease in outflows were partially offset by higher net originations of retail loans and direct financing leases $152.9 million in 2018 compared to $30.6 million in net collections in 2017.

Financing activities:  Cash used in financing activities decreased by $106.4 million to $339.3 million for the first quarter of 2018 from $445.7 million in 2017. The Company paid $510.1 million in dividends in the first quarter of 2018 compared to $294.7 million in 2017 due to a higher special dividend paid in January 2018. In the first quarter of 2018, the Company repurchased .3 million shares of common stock for $13.5 million, and there were no stock repurchases in 2017. In the first quarter of 2018, the Company issued $398.7 million of term debt, repaid term debt of $508.2 million, and increased its outstanding commercial paper and short-term bank loans by $284.3 million. In the first quarter of 2017, the Company issued $412.0 million of term debt, repaid term debt of $599.6 million and increased its outstanding commercial paper and short-term bank loans by $18.8 million. This resulted in cash provided by borrowing activities of $174.8 million in the first quarter of 2018, $343.6 million higher than the cash used in borrowing activities of $168.8 million in 2017.

PACCAR Inc – Form 10-Q

Credit Lines and Other

The Company has line of credit arrangements of $3.54 billion, of which $3.29 billion were unused at March 31, 2018. Included in these arrangements are $3.0 billion of syndicated bank facilities, of which $1.0 billion expires in June 2018, $1.0 billion expires in June 2021 and $1.0 billion expires in June 2022. The Company intends to replace these credit facilities on or before expiration with facilities of similar amounts and duration. These credit facilities are maintained primarily to provide backup liquidity for commercial paper borrowings and maturing medium-term notes. There were no borrowings under the syndicated bank facilities for the three months ended March 31, 2018.

On September 23, 2015, PACCAR’s Board of Directors approved the repurchase of up to $300.0 million of the Company’s common stock, and as of March 31, 2018, $222.8 million of shares have been repurchased pursuant to the 2015 authorization.

Truck, Parts and Other

The Company provides funding for working capital, capital expenditures, R&D, dividends, stock repurchases and other business initiatives and commitments primarily from cash provided by operations. Management expects this method of funding to continue in the future.

Investments for property, plant and equipment in the first quarter of 2018 were $64.0 million compared to $71.3 million for the same period of 2017. Over the past decade, the Company’s combined investments in worldwide capital projects and R&D totaled $6.08 billion, and have significantly increased the operating capacity and efficiency of its facilities and enhanced the quality and operating efficiency of the Company’s premium products.

In 2018, capital investments are expected to be $425 to $475 million and R&D is expected to be $300 to $320 million. The Company is investing in PACCAR’s new truck models, integrated powertrains including electric, hybrid and hydrogen fuel cell technologies, enhanced aerodynamic truck designs, advanced driver assistance and truck connectivity, and expanded manufacturing and parts distribution facilities.

The Company conducts business in certain countries which have been experiencing or may experience significant financial stress, fiscal or political strain and are subject to the corresponding potential for default. The Company routinely monitors its financial exposure to global financial conditions, global counterparties and operating environments. As of March 31, 2018, the Company’s exposures in such countries were insignificant.

Financial Services

The Company funds its financial services activities primarily from collections on existing finance receivables and borrowings in the capital markets. The primary sources of borrowings in the capital markets are commercial paper and medium-term notes issued in the public markets and, to a lesser extent, bank loans. An additional source of funds is loans from other PACCAR companies.

The Company issues commercial paper for a portion of its funding in its Financial Services segment. Some of this commercial paper is converted to fixed interest rate debt through the use of interest-rate swaps, which are used to manage interest-rate risk.

In November 2015, the Company’s U.S. finance subsidiary, PACCAR Financial Corp. (PFC), filed a shelf registration under the Securities Act of 1933. The total amount of medium-term notes outstanding for PFC as of March 31, 2018 was $4.35 billion. The registration expires in November 2018 and does not limit the principal amount of debt securities that may be issued during that period. PFC intends to renew the registration in 2018.

As of March 31, 2018, the Company’s European finance subsidiary, PACCAR Financial Europe, had €1.34 billion available for issuance under a €2.50 billion medium-term note program listed on the Professional Securities Market of the London Stock Exchange. This program replaced an expiring program in the second quarter of 2017 and is renewable annually through the filing of new listing particulars.

In April 2016, PACCAR Financial Mexico registered a 10.00 billion peso medium-term note and commercial paper program with the Comision Nacional Bancaria y de Valores. The registration expires in April 2021 and limits the amount of commercial paper (up to one year) to 5.00 billion pesos. At March 31, 2018, 6.85 billion pesos were available for issuance.

PACCAR Inc – Form 10-Q

In the event of a future significant disruption in the financial markets, the Company may not be able to issue replacement commercial paper. As a result, the Company is exposed to liquidity risk from the shorter maturity of short-term borrowings paid to lenders compared to the longer timing of receivable collections from customers. The Company believes its cash balances and investments, collections on existing finance receivables, syndicated bank lines and current investment-grade credit ratings of A+/A1 will continue to provide it with sufficient resources and access to capital markets at competitive interest rates and therefore contribute to the Company maintaining its liquidity and financial stability. A decrease in these credit ratings could negatively impact the Company’s ability to access capital markets at competitive interest rates and the Company’s ability to maintain liquidity and financial stability. PACCAR believes its Financial Services companies will be able to continue funding receivables, servicing debt and paying dividends through internally generated funds, access to public and private debt markets and lines of credit.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There were no material changes in the Company’s market risk during the three months ended March 31, 2018. For additional information, refer to Item 7A as presented in the 2017 Annual Report on Form 10‑K.

ITEM 4. CONTROLS AND PROCEDURES

The Company’s management, with the participation of the Principal Executive Officer and Principal Financial Officer, conducted an evaluation of the effectiveness of the Company’s disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)) as of the period covered by this report. Based on that evaluation, the Principal Executive Officer and Principal Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of the end of the period covered by this report.

There have been no changes in the Company’s internal controls over financial reporting that occurred during the fiscal quarter covered by this quarterly report that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II – OTHER INFORMATION

For Items 3, 4 and 5, there was no reportable information for the three months ended March 31, 2018.

ITEM 1.LEGAL PROCEEDINGS

On July 19, 2016, the European Commission (EC) concluded its investigation of all major European truck manufacturers and reached a settlement with DAF. Following the settlement, claims and lawsuits have been filed against the Company, DAF and certain DAF subsidiaries and other truck manufacturers. Others may bring EC related claims and lawsuits against the Company or its subsidiaries. While the Company believes it has meritorious defenses, such claims and lawsuits will likely take a significant period of time to resolve. An adverse outcome of such proceedings could have a material impact on the Company’s results of operations.

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

ITEM 1A.RISK FACTORS

New Accounting Pronouncements

New Revenue Standard

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers, including subsequently issued ASUs to clarify the implementation guidance in ASU 2014-09. Under the new revenue recognition model, a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The Company adopted this ASU for outstanding contracts on a modified retrospective basis on January 1, 2018.

The most significant effect of the standard relates to certain trucks sold in Europe that are subject to a residual value guarantee (RVG) and were accounted for as an operating lease in the Truck, Parts and Other section of the Company’s Consolidated Balance Sheets. Prior to the adoption of ASU 2014-09, these sales were recognized on a straight-line basis over the guarantee period. Under the new standard, revenues are recognized upon transfer of control for certain of these RVG contracts that allow customers the option to return their truck and for which there is no economic incentive to do so. The estimate of customers’ economic incentive to return the truck is based on an analysis of historical guaranteed buyback value and estimated market value. A return asset and liability is recognized for estimated returns. Return rates are estimated by using a historical weighted average return rate over a four-year period. Also as required by the new standard, the Company recognized an asset for the value of expected returned aftermarket parts which had previously been netted with the related liabilities.

The cumulative effect of the changes made to the Company’s Consolidated Balance Sheet on January 1, 2018 for the adoption of ASU 2014-09 was as follows:

New Pension Standard

In March 2017, FASB issued ASU 2017-07 Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The amendment disaggregates the service cost component from non-service cost components of pension expense and prescribes where to present the various components of pension cost on the income statement. This ASU also allows only the service cost component to be eligible for capitalization, when applicable (e.g. as a cost of manufactured inventory or self-constructed assets). The Company adopted this ASU in January 2018 and accordingly applied the income statement presentation of service and non-service components of pension expense retrospectively and the capitalization of service cost prospectively. Adoption of this ASU had no impact on net income. The retrospective application of this ASU had the following effects on the Consolidated Statement of Comprehensive Income:

Other Standards

In February 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2018-02 Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The amendment requires a reclassification from accumulated other comprehensive income (AOCI) to retained earnings the difference between the historical corporate income tax rate and the newly enacted income tax rate resulting from the Tax Act. This ASU is effective for annual periods beginning after December 15, 2018, and interim periods within those annual periods and early adoption is permitted. Upon adoption, the Company estimates Retained earnings will increase and AOCI will decrease approximately $30 million with no impact to Stockholders’ Equity. The Company expects to early adopt this ASU in the fourth quarter of 2018.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The amendment in this ASU requires entities having financial assets measured at amortized cost to estimate credit reserves under an expected credit loss model rather than the current incurred loss model. Under this new model, expected credit losses will be based on relevant information about past events, including historical experience, current conditions and reasonable and supportable forecasts that affect collectability. The ASU is effective for annual periods beginning after December 15, 2019 and interim periods within those annual periods. Early adoption is permitted, but not earlier than annual and interim periods beginning after December 15, 2018. This amendment should be applied on a modified retrospective basis with a cumulative effect adjustment to retained earnings as of the beginning of the period of adoption. The Company is currently evaluating the impact on its financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) which amends the existing accounting standards for leases. Under the new lease standard, lessees will recognize a right-of-use asset and a lease liability for virtually all leases (other than short-term leases). Lessor accounting is largely unchanged. The ASU is effective for annual periods beginning after December 15, 2018 and interim periods within those annual periods. Early adoption is permitted. This ASU requires leases to be recognized and measured at the beginning of the earliest period presented using a modified retrospective approach with optional practical expedients. The Company is currently evaluating the impact on its consolidated financial statements.

In addition to adopting the ASUs discussed above, the Company adopted the following standards effective January 1, 2018, none of which had a material impact on the Company’s consolidated financial statements.  

STANDARD	DESCRIPTION
2016-01 *	Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.

Sales And Revenues [Abstract]

Sales and Revenues

NOTE B – Sales and Revenues

The Company enters into sales contracts with customers associated with purchases of the Company’s products and services including trucks, parts, product support, and other related services. Generally, the Company recognizes revenue for the amount of consideration it will receive for delivering a product or service to a customer. Revenue is recognized when the customer obtains control of the product or receives benefits of the service. The Company excludes sales taxes, value added taxes and other related taxes assessed by government agencies from revenue. There are no significant financing components included in product or services revenue since, generally customers pay shortly after the products or services are transferred. In the Truck and Parts segment, when the Company grants extended payment terms on selected receivables and charges interest, interest income is recognized when earned.

The following table disaggregates Truck, Parts and Other revenues by major sources:  

	Three Months Ended
	March 31, 2018
Truck
Truck sales	$	4,174.4
Revenues from extended warranties, operating leases and other		178.6
		4,353.0
Parts
Parts sales	912.1
Revenues from dealer services and other		27.8
		939.9
Winch sales and other	28.9
Truck, Parts and Other sales and revenues	$	5,321.8

The Company recognizes truck and parts sales as revenue when control of the products is transferred to customers, except for certain truck sales which are subject to a residual value guarantee by the Company. The standard payment term for trucks and aftermarket parts is typically within 30 days, but the Company may grant extended payment terms on selected receivables. The Company recognizes revenue for the invoice amount adjusted for estimated sales incentives and returns. Sales incentives and returns are estimated based on historical experience and are adjusted to current period revenue when the most likely amount of consideration the Company expects to receive changes or becomes fixed.  Truck and part sales include a standard product warranty which is included in cost of sales. The Company has elected to treat delivery services as a fulfilment activity with revenues recognized when the customer obtains control of the product. Delivery revenue is included in revenues and the related costs are included in cost of sales. As a practical expedient, the Company is not disclosing truck order backlog, as a significant majority of the backlog has a duration of less than one year.

Truck sales with RVGs that allow customers the option to return their truck are accounted for as a sale when the customer does not have an economic incentive to return the truck to the Company, or as an operating lease when the customer does have an economic incentive to return the truck. The estimate of customers’ economic incentive to return the trucks is based on an analysis of historical guaranteed buyback value and estimated market value. When truck sales with RVGs are accounted for as a sale, revenue is recognized when the truck is transferred to the customer less an amount for expected returns. Expected return rates are estimated by using a historical weighted average return rate over a four-year period. The estimated value of the returned truck assets and the related return liabilities at March 31, 2018 were $199.9 and $208.8, respectively.  

Revenues from extended warranties, operating leases and other includes optional extended warranty and repair and maintenance service contracts which can be purchased for periods generally ranging up to five years. The Company defers revenue based on stand-alone observable selling prices when it receives payments in advance and recognizes the revenue on a straight-line basis over the warranty or repair and maintenance contract periods. See Footnote F, Product Support Liabilities, in the Notes to the Consolidated Financial Statements for further information. Also included are truck sales with an RVG accounted for as an operating lease. A liability is created for the residual value obligation with the remainder of the proceeds recorded as deferred revenue. The deferred revenue is recognized on a straight-line basis over the guarantee period, which typically ranges from three to five years. Deferred revenue related to trucks sold with a residual value guarantee was $686.8 at March 31, 2018. The Company expects to recognize approximately $149.2 of the remaining deferred revenue in 2018, $236.5 in 2019, $198.3 in 2020, $64.2 in 2021, $35.5 in 2022 and $3.1 thereafter.

Aftermarket parts sales allow for returns which are estimated at the time of sale based on historical data. The estimated value of the returned goods asset was $44.1 and the related return liability was $91.2 at March 31, 2018. The Company increased parts sales by $2.3 in the first quarter of 2018 due to changes in the reserve balance. Parts dealer services and other revenues are recognized as services are performed.

Revenue from winch sales and other is primarily derived from the industrial winch business. Winch sales are recognized when the product is transferred to a customer. Also within this category are other revenues not attributable to a reportable segment.

Investments in Marketable Debt Securities

Investments Debt And Equity Securities [Abstract]

Investments in Marketable Debt Securities

NOTE C - Investments in Marketable Debt Securities

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

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

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

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

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

Marketable debt securities at March 31, 2018 and December 31, 2017 consisted of the following:

	AMORTIZED		UNREALIZED		UNREALIZED		FAIR
At March 31, 2018	COST		GAINS		LOSSES		VALUE
U.S. tax-exempt securities	$	523.6			$	2.5	$	521.1

Other debt securities		142.8		.1		.7		142.2
	$	1,370.2	$	1.9	$	5.0	$	1,367.1

The cost of marketable debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Amortization, accretion, interest and dividend income and realized gains and losses are included in investment income. The cost of securities sold is based on the specific identification method. Gross realized gains were $.9 and $.5 and gross realized losses were $.5 and $.2 for the three month periods ended March 31, 2018 and 2017, respectively.  

Marketable debt securities with continuous unrealized losses and their related fair values were as follows:

	March 31, 2018				December 31, 2017
	LESS THAN		TWELVE MONTHS		LESS THAN		TWELVE MONTHS
	TWELVE MONTHS		OR GREATER		TWELVE MONTHS		OR GREATER
Fair value	$	841.6	$	22.7	$	908.5	$	18.4
Unrealized losses		6.1		.3		4.8		.2

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, 2018were as follows:

Inventories

NOTE D - Inventories

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

Inventories include the following:

	March 31			December 31
	2018			2017
Finished products	$	602.5		$	515.7
Work in process and raw materials		641.1			586.2
		1,243.6			1,101.9
Less LIFO reserve		(175.3	)		(173.5	)
	$	1,068.3		$	928.4

Under the LIFO method of accounting (used for approximately 44% of March 31, 2018 inventories), an actual valuation can be made only at the end of each year based on year-end inventory levels and costs. Accordingly, interim valuations are based on management’s estimates of those year-end amounts.

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 March 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.

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 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 2018 and five months in 2017 and did not have a significant effect on the weighted average term or interest rate of the total portfolio at March 31, 2018 and December 31, 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 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 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 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 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 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:

Credit Quality

The Company's customers are principally concentrated in the transportation industry in North America, Europe and Australia. The Company’s portfolio assets are diversified over a large number of customers and dealers with no single customer or dealer balances representing over 5% of the total portfolio assets. 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 tables below summarize the Company’s finance receivables by credit quality indicator and portfolio class.

There were $1.8 and $5.1 of finance receivables modified as TDRs during the previous twelve months that subsequently defaulted and were charged off in the three months ended March 31, 2018 and 2017, respectively.

Repossessions

When the Company determines 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 leases. The Company records the vehicles as used truck inventory included in Financial Services Other assets on the Consolidated Balance Sheets. The balance of repossessed inventory at March 31, 2018 and December 31, 2017 was $13.9 and $13.1, respectively. Proceeds from the sales of repossessed assets were $8.5 and $15.5 for the three months ended March 31, 2018 and 2017, respectively. These amounts are included in Proceeds from asset disposals in the Condensed Consolidated Statements of Cash Flows. Write-downs of repossessed equipment on operating leases are recorded as impairments and included in Financial Services Depreciation and other expenses on the Consolidated Statements of Comprehensive Income.

Product Warranties Disclosures [Abstract]

Product Support Liabilities

NOTE F - 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.

Changes in product support liabilities are summarized as follows:

WARRANTY RESERVES	2018			2017
Balance at January 1	$	298.8		$	282.1
Cost accruals		74.6			51.3

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 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 for the year ended December 31, 2017.

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 a portion of corporate expenses.

Derivative Instruments And Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

NOTE J - 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 derivatives not designated as hedging instruments. 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 $45.7 at March 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. 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. 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 Consolidated Statements of Cash Flows.

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

At March 31, 2018, the notional amount of the Company’s interest-rate contracts was $3,155.6. Notional maturities for all interest-rate contracts are $906.7 for the remainder of 2018, $934.1 for 2019, $450.2 for 2020, $634.4 for 2021, $141.8 for 2022, $15.8 for 2023 and $72.6 thereafter.

Foreign-Exchange Contracts:The Company enters into foreign-exchange contracts to hedge certain anticipated transactions and assets and liabilities denominated in foreign currencies, particularly the Canadian dollar, the euro, the British pound, the Australian dollar, the Brazilian real and the Mexican peso. The objective is to reduce fluctuations in earnings and cash flows associated with changes in foreign currency exchange rates. At March 31, 2018, the notional amount of the outstanding foreign-exchange contracts was $523.7. Foreign-exchange contracts mature within one year.

The following table presents the balance sheet classification, fair value, gross and pro forma net amounts of derivative financial instruments:

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 March 31, 2018, the following amounts were recorded on the Consolidated Balance Sheets related to cumulative basis adjustments for fair value hedges:

			Cumulative Basis
	Carrying Amount of		Amount Included in
Hedged Balance Sheet Line Item	the Hedged Liabilities		the Carrying Amount
Medium-term notes	$	280.5	$	(4.5	)

The above table excludes the cumulative basis adjustments on discontinued hedge relationships of ($2.4) million as of March 31, 2018.

Cash Flow Hedges

Substantially all of the Company’s interest-rate contracts and some foreign-exchange contracts have been designated as cash flow hedges. 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. Changes in the fair value of derivatives designated as cash flow hedges are recorded in AOCI. 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 9.9 years.

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

The amount of gain recorded in AOCI at March 31, 2018 that is estimated to be reclassified into earnings in the following 12 months if interest rates and exchange rates remain unchanged is approximately $2.6, net of taxes.

Derivatives Not Designated As Hedging Instruments

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 derivatives not designated as hedging instruments are recorded in earnings in the period in which the change occurs.

For the quarters ended March 31, 2018 and 2017, the 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:

Fair Value Disclosures [Abstract]

Fair Value Measurements

NOTE K - 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 themeasurement 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, 2018. The Company’s policy is to recognize transfers between levels at the end of the reporting period.

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

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

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

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

Assets and Liabilities Subject to Recurring Fair Value Measurement

Fair Value Disclosure of Other Financial Instruments

For financial instruments that are not recognized at fair value, the Company uses the following methods and assumptions to determine the fair value. These instruments are categorized as Level 2, except cash which is categorized as Level 1 and fixed rate loans which are categorized as Level 3.

Cash and Cash Equivalents: Carrying amounts approximate fair value.

Financial Services Net Receivables: For floating-rate loans, wholesale financings, and 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 the credit and market risks to approximate current rates for comparable loans. Finance lease receivables and related allowance for credit losses have been excluded from the accompanying table.

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

The Company’s estimate of fair value for fixed rate loans and debt that are not carried at fair value was as follows:

	March 31, 2018				December 31, 2017

Accounting Policies (Policies)

Accounting Policies [Abstract]

Investment in Marketable Debt Securities

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

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

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

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

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

Inventories

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

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 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 2018 and five months in 2017 and did not have a significant effect on the weighted average term or interest rate of the total portfolio at March 31, 2018 and December 31, 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 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 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 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 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.

Derivative Financial Instruments

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 derivatives not designated as hedging instruments. 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 $45.7 at March 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. 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. 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 Consolidated Statements of Cash Flows.

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 themeasurement 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, 2018. The Company’s policy is to recognize transfers between levels at the end of the reporting period.

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

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

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

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