Performance Obligations

Substantially all of the Company’s revenues are recognized at a point in time as results from services are provided through a screening report and the customer takes control of the product when the report is completed. Accordingly, revenue is generally recognized at the point in time when the customer receives and can use the report.

For revenue arrangements containing multiple products or services, the Company accounts for the individual products or services as separate performance obligations if they are distinct, the product or service is separately identifiable from other terms in the contract, and if a customer can benefit from it on its own or with other resources that are readily available to the customer. If these criteria are not met, the promised products or services are accounted for as a combined performance obligation. The Company allocates the contract price to each performance obligation based on the standalone selling prices of each distinct product or service in the contract.

Contract Assets and Liabilities

Incremental costs of obtaining a contract with a customer are recognized as an asset if the benefit of such costs is expected to be longer than one year, with a majority of contracts being multi-year. Incremental costs include commissions to the sales force and are amortized over three years, as management estimates that this corresponds to the period over which a customer benefits from the contract. As of December 31, 2020 and September 30, 2021, $3.3 million and $2.9 million, respectively, of deferred commissions are included in Other current assets on the unaudited condensed consolidated balance sheets and approximately $2.1 million and $2.5 million, respectively, of deferred commissions are included in Other noncurrent assets, net on the unaudited condensed consolidated balance sheets.

The Company did not have any material contract liabilities as of December 31, 2020 and September 30, 2021.

Concentrations

For the three and nine months ended September 30, 2020 and 2021, no single customer accounted for more than 10% of the Company’s revenue. No single customer had an accounts receivable balance greater than 10% of total accounts receivable as of December 31, 2020 and September 30, 2021.
