FD&A costs can be calculated either including or excluding future development capital ("FDC"). FD&A costs under NI 51-101 include FDC as this provides a more representative view of the full cost of reserve additions as it accounts for future costs to bring the reserves to market. Under the historic method, FD&A costs are understated as reserves are included without taking into account the future capital expenditures required to fully develop the reserve base. We have included both the NI 51-101 method which includes FDC and the historic method for comparison purposes.
