Bob the Builder purchased a land and building in Year 6 for $4,000,000. $1.6 million of the purchase price was allocated to the land, and the balance to the building. At the time of the purchase it was estimated that the building would have a useful life of 40 years but no residual value.

In Year 18 Bob exchanged the land and building for a piece of undeveloped land. The fair market value of the assets given up was estimated to be $6.2 million and the fair value of the land to be received was $6.1 million. To make up the difference in the fair values of the assets exchanged, Bob also received $100,000 cash

Bob depreciates his buildings using the straight-line method. Bob adopts half-year convention for depreciation.
