NOTE A - Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10‑Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals and the non-recurring European Commission charge) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017. For further information, refer to the consolidated financial statements and footnotes included in PACCAR Inc’s (PACCAR or the Company) Annual Report on Form 10‑K for the year ended December 31, 2016.

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

	Three Months Ended				Nine Months Ended
	September 30				September 30
	2017		2016		2017		2016
Additional shares		1,035,000		738,500		1,021,000		679,400

New Accounting Pronouncements: In March 2017, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (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 will adopt this ASU in January 2018 and accordingly will apply the income statement presentation of service and non-service components of pension expense retrospectively and the capitalization of service cost prospectively. Non-service components of pension expense (see Note K) are currently reported in Cost of sales and revenues and Selling, general and administrative expenses. Upon adoption of this ASU these costs will be reported in Interest and other expenses, net in the Company’s Truck, Parts and Other segments.

In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. The amendment in this ASU requires recognition of income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. Currently the recognition of current and deferred income taxes for an intra-entity asset transfer is recognized when the asset has been sold to an outside party. This ASU is effective for annual reporting periods beginning after December 15, 2017 and interim periods within those annual periods, and early adoption is permitted. 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 adopted this ASU on January 1, 2017. The effect of the adoption reduced prepaid income taxes and retained earnings by $19.9. Because the corresponding deferred tax asset is not realizable, the Company recorded an offsetting valuation allowance.

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 consolidated 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. The Company is currently evaluating the impact on its consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. This ASU amends the existing accounting standards for revenue recognition. 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 FASB has subsequently issued several related ASUs to clarify the implementation guidance in ASU 2014-09. This standard may be applied retrospectively to each prior period presented or modified retrospectively with a cumulative effect recognized as of the date of initial application. The Company expects to adopt this ASU in January 2018 on a modified retrospective basis, with the cumulative effect adjustment recognized into retained earnings as of January 1, 2018.

The Company’s evaluation of the new standard is substantially complete, and the Company does not expect adoption of the new standard to have a material impact on the income statement or retained earnings. The Company currently expects the most significant effect of the standard relates to trucks sold in Europe that are subject to a residual value guarantee (RVG) and are currently accounted for as an operating lease in the Truck, Parts and Other section of the Company’s Consolidated Balance Sheets (see Note E in the 2016 Form 10-K). Under the new standard, based on the Company’s current assessment, revenues would be recognized immediately 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. Based on the existing portfolio of RVG contracts, under the new standard, revenues are expected to be recognized immediately for approximately half of the RVG portfolio instead of being deferred and amortized over the life of the RVG contract. The Company will continue to evaluate the new standard, including any new interpretive guidance, and any related impact to its consolidated financial statements.

In addition to ASU 2016-16 disclosed above, the Company adopted the following standards effective January 1, 2017, none of which had a material impact on the Company’s consolidated financial statements.
