Future Development Costs ("FDC")
NI 51-101 requires that future development costs be calculated including changes in FDC. Changes in forecast FDC occur annually as a result of development activities, acquisition and disposition activities and capital cost estimates that reflect the independent evaluators' best estimate of what it will cost to bring the proved undeveloped and probable reserves on production.
