The Company does not operate in separate reportable segments. Shipments to international customers generally require a prepayment either by wire transfer or an irrevocable confirmed letter of credit.  The Company does extend credit to international customers on some occasions depending upon certain criteria, including, but not limited to, the credit worthiness of the customer, the stability of the country, banking restrictions, and the size of the order.  All transactions are in U.S. currency.
