Concentrations of Credit Risk
Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents and trade receivables. The Company maintains cash deposits with financial institutions that, from time to time, exceed applicable insurance limits. The Company reduces this risk by maintaining such deposits with high quality financial institutions that management believes are creditworthy. Cash and cash equivalents are maintained with several financial institutions domestically and internationally. The combined account balances held on deposit at each institution typically exceed Federal Deposit Insurance Corporation (“FDIC”) insurance coverage and, as a result, there is a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage. The Company monitors this credit risk and makes adjustments to the concentrations as necessary. As of December 31, 2022 and 2021, the Company had total domestic cash deposits and cash equivalents of $256.7 million and $213.6 million, respectively. Total domestic cash deposits exceeded the FDIC insurance coverage amounts.
With respect to accounts receivable, credit risk is mitigated by the Company’s ongoing credit evaluation of its customers’ financial condition. No single customer accounted for more than 10 percent of trade receivables for the years ended December 31, 2022 and 2021. With respect to revenues, no single customer accounted for more than 10% of revenues for the years ended December 31, 2022, 2021 and 2020.
