Asset retirement obligations are recognized for decommissioning of specific nuclear power units prescribed by the "Act on the Regulation of Nuclear Source Material, Nuclear Fuel Material and Reactors."
Based on the "Ministerial Ordinance on Reserves for Decommissioning Costs of Nuclear Power Units" (Ordinance of MITI No.30 of 1989), the total estimate of decommission expense is recognized by the straight-line method over the expected operating period of nuclear power units and planned period for safe storage.
Remaining years are determined by each unit at the period which includes the planned period for safe storage in addition to the expected operation period of nuclear power units after deducting the past operation period.
Discount rate of 2.3% is used in the calculation.
