Concentration of Risk	12 Months Ended
	Dec. 31, 2020
Risks and Uncertainties [Abstract]
Concentration of Risk	Concentration of Risk The Company generates a significant amount of revenue from large clients; however, no individual client accounted for 10% or more of total revenue in the years ended December 31, 2020, 2019 and 2018. Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash equivalents and trade receivables. The Company places its cash equivalents with high credit-quality financial institutions and, by policy, limits the amount of credit exposure with any one financial institution. Concentrations of credit risk with respect to trade receivables are limited because a large number of geographically diverse clients make up the Company's client base, thus spreading the trade receivables credit risk. The Company controls credit risk through monitoring procedures.
