Subsequent Events [Abstract]
SUBSEQUENT EVENT	SUBSEQUENT EVENTOn January 28, 2021, we entered into the Third Amendment of our Revolving Credit Facility, which clarified the definition of the Asset Coverage Ratio financial covenant. The effective date of the Third Amendment was the last day of fiscal 2020 (December 27, 2020). The Third Amendment clarified the difference between the total outstanding balance of the Revolving Credit Facility and 60.0% of accounts receivable and unrestricted cash in excess of $50.0 million may not be less than zero. If the amount is less than zero, then the Asset Coverage Ratio is defined as the ratio of 60.0% of accounts receivable to total debt outstanding.

The entire disclosure for significant events or transactions that occurred after the balance sheet date through the date the financial statements were issued or the date the financial statements were available to be issued. Examples include: the sale of a capital stock issue, purchase of a business, settlement of litigation, catastrophic loss, significant foreign exchange rate changes, loans to insiders or affiliates, and transactions not in the ordinary course of business.
