Revenue from Contract with Customer [Abstract]

Revenue

Significant Accounting Policy

We account for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers (ASC Topic 606), which we adopted on January 1, 2018, using the modified retrospective method. Revenue is measured based on the consideration specified in a contract with a customer. Most of our contracts with customers contain transaction prices with fixed consideration, however, some contracts may contain variable consideration in the form of discounts, rebates, refunds, credits, price concessions, incentives, performance bonuses, penalties and other similar items. When a contract includes variable consideration, we evaluate the estimate of variable consideration to determine whether the estimate needs to be

constrained; therefore, we include the variable consideration in the transaction price only to the extent that it is probable that a significant reversal of the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. We recognize revenue when we satisfy a performance obligation by transferring control over a product or service to a customer. This can result in recognition of revenue over time as we perform services or at a point in time when the deliverable is transferred to the customer, depending on an evaluation of the criteria for over time recognition in ASC Topic 606. Further details regarding our revenue recognition for various revenue streams are discussed below.

Nature of goods and services

Over 90% of our revenue is derived from services provided to our customers for training, consulting, technical, and other services. Less than 10% of our revenue is derived from various other offerings including custom magazine publications and assembly of glovebox portfolios for automotive manufacturers, licenses of software and other intellectual property, and software as a service (SaaS) arrangements.

Our primary contract vehicles are time-and-materials, fixed price (including fixed-fee per transaction) and cost-reimbursable contracts. Each contract has different terms based on the scope, deliverables and complexity of the engagement, requiring us to make judgments and estimates about recognizing revenue.

Under time-and-materials and cost-reimbursable contracts, the contractual billing schedules are based on the specified level of resources we are obligated to provide. Revenue under these contract types are recognized over time as services are performed as the client simultaneously receives and consumes the benefits provided by our performance throughout the engagement. The time and materials incurred for the period is the measure of performance and, therefore, revenue is recognized in that amount.

For fixed price contracts which typically involve a discrete project, such as development of training content and materials, design of training processes, software implementation, or engineering projects, the contractual billing schedules are not necessarily based on the specified level of resources we are obligated to provide. These discrete projects generally do not contain milestones or other measures of performance. The majority of our fixed price contracts meet the criteria in ASC Topic 606 for over time revenue recognition. For these contracts, revenue is recognized using a costs incurred input method based on the relationship of costs incurred to total estimated costs expected to be incurred over the term of the contract. We believe this methodology is a reasonable measure of progress to depict the transfer of control to the customer since performance primarily involves personnel costs and services provided to the customer throughout the course of the projects through regular communications of progress toward completion and other project deliverables. In addition, the customer is required to pay us for the proportionate amount of our fees in the event of contract termination. A small portion of our fixed price contracts do not meet the criteria in ASC Topic 606 for over time revenue recognition. For these projects, we defer revenue recognition until the performance obligation is satisfied, which is generally when the final deliverable is provided to the client. The direct costs related to these projects are capitalized and then recognized as cost of revenue when the performance obligation is satisfied.

For fixed price contracts, when total direct cost estimates exceed revenues, the estimated losses are recognized immediately. The use of the costs incurred input method requires significant judgment relative to estimating total contract costs, including assumptions relative to the length of time to complete the project, the nature and complexity of the work to be performed, and anticipated changes in estimated salaries and other costs. Estimates of total contract costs are continuously monitored during the term of the contract, and recorded revenues and costs are subject to revision as the contract progresses. When revisions in estimated contract revenues and costs are determined, such adjustments are recorded in the period in which they are first identified. Revenue recognized in the reporting period from performance obligations satisfied (or partially satisfied) in previous periods to our fixed price contracts in the aggregate resulted in a net increase (decrease) to revenue of $(0.8) million, $1.8 million, and $1.5 million for the years ended December 31, 2020, 2019 and 2018, respectively.

For certain fixed-fee per transaction contracts, such as delivering training courses or conducting workshops, revenue is recognized during the period in which services are delivered in accordance with the pricing outlined in the contracts.

For certain fixed-fee per transaction and fixed price contracts, such as for the shipping of publications and print materials, revenue is recognized at the point in time at which control is transferred which is upon delivery, as the over time revenue recognition criteria per ASC 606-10-25-27 are not met.

Taxes assessed by a government authority that are both imposed on and concurrent with a specific revenue-producing transaction, that we collect from a customer, are excluded from revenue.

Performance Obligations

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in ASC Topic 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. For contracts with multiple performance obligations, we allocate the contract’s transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. As of December 31, 2020 we had $316.1 million of remaining performance obligations, which we also refer to as total backlog. We anticipate to recognize approximately 85 percent of our remaining performance obligations within the next twelve months.

Contract Balances

Revenue recognized for the years ended December 31, 2020 and 2019, that was included in the contract liability balance at the beginning of the year was $14.5 million and $18.9 million, respectively, and primarily represented revenue from services performed during the current period for which we received advance payment from clients in a prior period.

Contract Costs

Costs to fulfill contracts which do not meet the over time revenue recognition criteria are capitalized and recognized to cost of revenue when the performance obligation is satisfied and revenue is recognized. Such costs are included in prepaid expenses and other current assets on the consolidated balance sheet and totaled $0.6 million for both December 31, 2020 and 2019.

Applying the practical expedient in ASC Topic 606, we recognize the incremental costs of obtaining contracts (i.e. sales commissions) as an expense when incurred if the amortization period of the assets that we otherwise would have recognized is one year or less. As of December 31, 2020 and 2019, we did not have any capitalized sales commissions.
