[1] Restricted cash consists mainly 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 $8.4 million with a few of its lenders as compensating balances for several U.S. dollar denominated loans payable over several years. The certificates of deposit will be reduced annually commensurate with the loan balances.
