Factored accounts receivable, description			Certain of the Company’s wholly-owned subsidiaries have entered into accounts receivable factoring arrangements with a financial institution (the “Factor”) with termination dates starting in September 2021 that automatically renew for successive one-year periods (absent either party's written election to terminate, which did not occur). Pursuant to the terms of the agreements, the Company, from time to time, sells to the Factor certain of its accounts receivable balances on a recourse basis for credit-approved accounts. The Factor remits 95% of the contracted accounts receivable balance for a given month to the Company (the “Advance Amount”) with the remaining balance, less fees, to be forwarded once the Factor collects the full accounts receivable balance from the customer.
