The factors that impact the timing and amount of revenue recognized for each service line may vary based on the nature of the service performed. Generally, the Company recognizes revenue at the time it performs a service. In the event that the Company bills for services in advance of performance, it recognizes deferred revenue for the amount billed and subsequently recognizes revenue at the time the service is provided.  Substantially all of the deferred revenue recorded as of March 31, 2022 was recognized as revenue during the three months ended June 30, 2022 when the service was performed.

See Note 10 for additional information regarding revenue by reportable segment.

Contract Acquisition Costs

The incremental direct costs of obtaining a contract, which consist of sales incentives, are recognized as Other assets in the Company’s Condensed Consolidated Balance Sheet, and are amortized to Selling, general and administrative expense over the estimated life of the relevant customer relationship, which ranges from one to five years. The Company recognizes the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset

that the entity would have recognized is one year or less.  The Company had $19,627 and $18,954 of deferred sales incentives at June 30, 2022 and December 31, 2021, respectively.
