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) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013. For further information, refer to the consolidated financial statements and footnotes included in PACCAR Inc’s (the Company) Annual Report on Form 10-K for the year ended December 31, 2012.

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.

New Accounting Pronouncements: In July 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. This ASU requires an unrecognized tax benefit, or a portion of an unrecognized tax benefit, to be presented in the consolidated financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward if available under the applicable tax jurisdiction. The ASU is effective for annual periods beginning after December 15, 2013 and interim periods within those annual periods. The Company does not expect the adoption of the ASU to have a material impact on its consolidated financial statements.

In July 2013, the FASB issued ASU 2013-10, Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes. The amendments in this ASU permit the Fed Funds Effective Swap Rate (OIS) to be used as a U.S. benchmark interest rate for hedge accounting purposes in addition to U.S. government and London Interbank Offered Rate. The amendments also remove the restriction on using different benchmark rates for similar hedges. The ASU is effective for qualifying new or redesignated hedging relationships entered on or after July 17, 2013. The Company adopted ASU 2013-10 in the third quarter of 2013; the implementation of this amendment did not have an impact on the Company’s consolidated financial statements.

In February 2013, the FASB issued ASU 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. This ASU requires disclosure of additional information about reclassification adjustments from other comprehensive income. The ASU is effective for annual periods beginning on or after January 1, 2013 and interim periods within those annual periods. The Company adopted ASU 2013-02 in the first quarter of 2013; the implementation of this amendment resulted in additional disclosures (see Note F), but did not have an impact on the Company’s consolidated financial statements.

In January 2013, the FASB issued ASU 2013-01, Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities, an update to ASU 2011-11, Disclosures about Offsetting Assets and Liabilities. The ASUs require entities with derivatives, repurchase agreements and securities borrowing and lending transactions that are either offset on the balance sheet, or subject to a master netting arrangement, to provide expanded disclosures about the nature of the rights of offset. The updated ASU is effective for annual periods beginning on or after January 1, 2013 and interim periods within those annual periods. The Company adopted ASU 2013-01 in the first quarter of 2013; the implementation of this amendment resulted in additional disclosures (see Note I), but did not have an impact on the Company’s consolidated financial statements.
