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:

	BALANCE AT DECEMBER 31, 2017		CHANGE DUE TO NEW STANDARD			BALANCE AT JANUARY 1, 2018

Other current assets	$	404.4	$	100.0		$	504.4

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:

Three Months Ended March 31, 2017	PREVIOUSLY REPORTED			EFFECTS OF NEW STANDARD			CURRENTLY REPORTED
Consolidated Statements of Comprehensive Income
TRUCK, PARTS AND OTHER:
Cost of sales and revenues	$	3,382.2		$	8.7		$	3,390.9
Selling, general and administrative		111.3			3.2			114.5
Interest and other (income), net		(1.6	)		(12.4	)		(14.0	)
Truck, Parts and Other Income Before Income Taxes		382.8			.5			383.3

FINANCIAL SERVICES:
Selling, general and administrative		25.2			.5			25.7
Financial Services Income Before Income Taxes		57.3			(.5	)		56.8

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.
