[1] Restricted cash consists of cash deposits held within banking institutions in compliance with federal regulatory requirements in Costa Rica and Panama. In addition, the Company is required to maintain a certificate of deposit and/or security deposits of Trinidad dollars, as measured in U.S. dollars, of approximately $10.0 million with a few of its lenders as compensating balances for several U.S. dollar and euro denominated loans payable over several years. The certificates of deposit will be reduced annually commensurate with the loan balances.
