All of the Post-1989 forests promoted by Forest Enterprises have entered into a into a commercial arrangement with a company called New Zealand Forest Leasing Ltd (NZFL), resulting in the carbon in the Post-1989 areas of the forest being leased to New Zealand Carbon Leasing (No. 1) Limited, a subsidiary of NZFL, in return for an annual rental. This means that generally the income for each Post-1989 forest is sufficient to cover the annual expenditure and the Call amounts are therefore $0.
