22. CONCENTRATION

   

Financial instruments, which potentially subject the Company to concentrations of credit risk, consist primarily of trade accounts receivable. The Company performs ongoing credit evaluations of its customers and generally does not require collateral related to its trade accounts receivable. At March 31, 2020, accounts receivable from three customers comprised 71% of the Company's total trade accounts receivable, and none of this balance had been characterized as uncollectible as of March 31, 2020.
