Adoption of ASC Topic 606, “Revenue from Contracts with Customers”

On January 1, 2018, the Company adopted ASC Topic 606 using the modified retrospective method. Results for periods beginning January 1, 2018 and later are presented under ASC Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with the Company’s historical accounting policy for revenue recognition.

We recorded a $2.0 million net increase to the opening balance of retained earnings as of January 1, 2018, for the cumulative impact of adopting the new guidance. The impact primarily related to the change in accounting for shipments in transit as of December 31, 2017. ASC Topic 606 requires us to recognize revenue and related direct costs over time as the shipment is being delivered. Prior to adopting the new guidance, we recognized revenue and related direct costs when the shipment was delivered.

Under the modified retrospective method of adoption, we are required to disclose the impact to our financial statements had we continued to follow our accounting policies under the previous revenue recognition guidance. Had we continued to recognize revenues and direct costs upon delivery, our operating revenues and operating expenses for the three months ended June 30, 2018 would have been been lower by approximately $0.7 million and $0.3 million, respectively, and for the six months ended June 30, 2018 would have been lower by approximately $1.0 million and $0.4 million, respectively. Additionally, under ASC Topic 606, we recorded a $3.9 million and $7.1 million reduction of revenues for the three and six months ended June 30, 2018, respectively, related to our driver training schools that would have been reported as bad debt expense prior to the new standard.

Revenue Recognition

Revenues are recognized over time as control of the promised services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those services.

The following table presents our revenues disaggregated by revenue source (in thousands):

The following table presents our revenues disaggregated by geographic areas in which we conduct business (in thousands). Operating revenues for foreign countries include revenues for (i) shipments with an origin or destination in that country and (ii) other services provided in that country. If both the origin and destination are in a foreign country, the revenues are attributed to the country of origin.

Transportation Services

We generate nearly all of our revenues by transporting truckload freight shipments for our customers. Transportation services are carried out by our Truckload Transportation Services (“Truckload”) segment and our Werner Logistics (“Logistics”) segment. The Truckload segment utilizes company-owned and independent contractor trucks to deliver shipments, while the Logistics segment uses third-party capacity providers.

The Company generates revenue from billings for transportation services under contracts with customers, generally on a rate per mile or per shipment, based on origin and destination of the shipment. The Company’s performance obligation arises when it receives a shipment order to transport a customer’s freight and is satisfied upon delivery of the shipment. The transaction price may be defined in a transportation services agreement or negotiated with the customer prior to accepting the shipment order. A customer may submit several shipment orders for transportation services at various times throughout a service agreement term, but each shipment represents a distinct service that is a separately identified performance obligation. The Company often provides additional or ancillary services as part of the shipment (such as loading/unloading and stops in transit) which are not distinct or are not material in the context of the contract; therefore the revenue for these services is recognized with the freight transaction price. The average transit time to complete a shipment is approximately 3 days. Invoices for transportation services are typically generated soon after shipment delivery and, while payment terms and conditions vary by customer, are generally due within 30 days after the invoice date.

The Consolidated Statements of Income reflect recognition of transportation revenues (including fuel surcharge revenues) and related direct costs over time as the shipment is being delivered. The Company uses distance shipped (for the Truckload segment) and transit time (for the Logistics segment) to measure progress and the amount of revenue recognized over time, as the customer simultaneously receives and consumes the benefit. Determining a measure of progress requires us to make judgments that affect the timing of revenue recognized. The Company has determined that the methods described provide a faithful depiction of the transfer of services to the customer.

For shipments where a third-party capacity provider (including independent contractors under contract with us) is utilized to provide some or all of the service, we evaluate whether we are the principal (i.e., report revenues on a gross basis) or agent (i.e., report revenues on a net basis). Generally, we report such revenues on a gross basis, that is, we recognize both revenues for the service we bill to the customer and rent and purchased transportation expense for transportation costs we pay to the third-party provider. Where we are the principal, we control the transportation service before it is provided to our customers, which is supported by us being primarily responsible for fulfilling the shipment obligation to the customer and having a level of discretion in establishing pricing with the customer.

During the first half of 2018, revenue recognized from performance obligations related to prior periods (for example, due to changes in transaction price) was not material.

Other Revenues

Other revenues include revenues from our driver training schools, transportation-related activities such as third-party equipment maintenance and equipment leasing, and other business activities. These revenues are generally recognized over time and accounted for 2% of our total revenue in the first half of 2018. Revenues from our driver training schools require us to make judgments regarding price concessions in determining the amount of revenue to recognize.

Contract Balances and Accounts Receivable

A receivable is an unconditional right to consideration and is recognized when shipments have been completed and the related performance obligation has been fully satisfied. At June 30, 2018 and December 31, 2017, the accounts receivable, net, balance was $333.1 million and $304.2 million, respectively. Contract assets represent a conditional right to consideration in exchange for goods or services, and are transferred to receivables when the rights become unconditional. At June 30, 2018, the balance of contract assets was $8.8 million, and the balance was $7.8 million at January 1, 2018, after adopting ASC Topic 606. The Company has recognized contract assets within the other current assets financial statement caption on the balance sheet. These are considered current assets as they will be settled in less than 12 months.

Contract liabilities represent advance consideration received from customers, and are recognized as revenue over time as the related performance obligation is satisfied. At June 30, 2018 and December 31, 2017, the balance of contract liabilities was $2.4 million and $2.1 million, respectively. The amount of revenue recognized in the first half of 2018 that was included in the December 31, 2017 contract liability balance was $2.1 million. The Company has recognized contract liabilities within the accounts payable and other current liabilities financial statement captions on the balance sheet. These are considered current liabilities as they will be settled in less than 12 months.

Performance Obligations

We have elected to apply the practical expedient in ASC Topic 606 to not disclose the value of remaining performance obligations for contracts with an original expected length of one year or less. Remaining performance obligations represent the transaction price allocated to future reporting periods for freight shipments started but not completed at the reporting date that we expect to recognize as revenue in the period subsequent to the reporting date; transit times generally average approximately 3 days.
