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$$s contract with OL requires BNL to dismantle the tower if and when BNL discontinues its use. BNL expects to use the tower for only $10$ years due to the rapid advance in transmission technology that is likely to render the tower obsolete in $10$ years. The lease payments to OL are $$410,000$ per year.

BNL constructed the tower at the beginning of $20$X$6$ at a cost of $$4,879,000.$ BNL estimates that dismantling and removal of the tower will cost $$430,000.$ 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.
