13.	MAJOR CUSTOMERS AND CONCENTRATION OF CREDIT RISK

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, and restricted cash and trade accounts receivable. At times, cash balances may exceed the Federal Deposit Insurance Corporation (“FDIC”) insurable limits of $250,000 per depositor at each financial institution. The Company has never experienced any losses related to these balances. Non-interest-bearing amounts on deposit in excess of FDIC insurable limits at December 31, 2020 and June 30, 2020 approximated $5.71 million and $2.01 million, respectively. Interest-bearing amounts on deposit in excess of FDIC insurable limits at December 31, 2020 and June 30, 2020 approximated $10.64 million and $11.64 million, respectively.

Trade receivables potentially subject the Company to credit risk. Payment terms on trade receivables for the Company’s Traditional segment customers are generally between 30 and 90 days, though it may offer extended terms with specific customers and on significant orders from time to time. The Company extends credit to its customers based upon a number of factors, including an evaluation of the customer’s financial condition and credit history that is verified through trade association reference services, the customer’s payment history with the Company, the customer’s reputation in the trade, and/or an evaluation of the Company’s opportunity to introduce its moissanite jewels or finished jewelry featuring moissanite to new or expanded markets. Collateral is not generally required from customers. The need for an allowance for doubtful accounts is determined based upon factors surrounding the credit risk of specific customers, historical trends, and other information.

For additional information regarding the Company’s measurement and disclosure of credit losses on financial assets, including trade accounts receivable, see Note 4, “Fair Value Measurements.”
