Decommissioning Obligation (10 marks) Bruce Networks Ltd. (BNL) has a 10-year renewable lease contract with Open Ltd. (OL), the owner of a tall building in a major city. BNL is permitted to erect a transmission tower on the top of the building. BNL's contract with OL requires BNL to dismantle the tower if and when BNL discontinues its use. BNL expects to use the tower for only 10 years due to the rapid advance in transmission technology that is likely to render the tower obsolete in 10 years. The lease payments to OL are $445,000 per year. BNL constructed the tower at the beginning of 20x6 at a cost of $5,607,000. BNL estimates that dismantling and removal of the tower will cost $500,000. The pre-tax interest rate that reflects risk is 6%. BNL plans to use straight-line depreciation; the company's policy is to take a full year's depreciation in the year of acquisition but none in the year of disposal.
