A contributes $100,000 cash to the equal AB partnership, and B contributes a building with an adjusted basis of $40,000 and a fair market value of $100,000. Assume that the recovery period for the building is 20 years (straight line) of which 10 years remain when B contributes it to the AB partnership. AB elects the remedial method of allocation for the building. The property is sold by AB for $60,000 at the beginning of year 3. What are the tax and book effects of depreciation in years 1 and 2 and of the gain/loss on the sale in year 3?
