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:

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.
