Concentration of Credit Risk [Abstract] |  |
CONCENTRATION OF CREDIT RISK | 20. CONCENTRATION OF CREDIT RISK Financial instruments that potentially expose the Group to concentrations of credit risk consist primarily of accounts receivable. The Group conducts credit evaluations of its Customers, and generally does not require collateral or other security from them. The allowance for credit losses for accounts receivable is based upon the current expected credit losses (“CECL”) model. The CECL model requires an estimate of the credit losses expected over the life of accounts receivable since initial recognition, and accounts receivable with similar risk characteristics are grouped together when estimating CECL. The Group conducts periodic reviews of the financial condition and payment practices of its Customers to minimize collection risk on accounts receivable. The following table sets forth a summary of single Customers who represent 10% or more of the Group’s total revenue.
