An oil refinery has decided to purchase some new drilling equipment for $140,000. The equipment will be kept for 10 years before being sold. The estimated MV at the end of 10 years is $11,000. If MACRS depreciation is used, under GDS guidelines, what is the taxable gain (MV-BV) on the disposal of the equipment? The firm’s effective income tax rate is 40%, and its after-tax MARR is 15%.
