[1] A clause in the banking facilities states that the term loans are subject to review any time and also subject to the bank's overriding right of repayment on demand, including the right to call for cash cover on demand for prospective and contingent liabilities. Therefore, all long-term loans were classified as current liabilities in the consolidated balance sheets.
