Line of credit facility, borrowing capacity, description		The Company is required to maintain a borrowing base comprising the value of the Company’s trademarks that exceeds the outstanding balance of the term loans. If the borrowing base is less than the outstanding term loans at any measurement period, then the Company would be required to repay a portion of the term loans to eliminate such shortfall. Events of default include, among other things, the occurrence of a change of control of the Company, and a default under the term loans agreement would also trigger a default under the Junior Notes agreements.
