Cuda Marine Engines, Inc. must develop the cash flow estimates for a replacement capital investment proposal. The proposed asset costs $50,000 and has installation costs of $3,000. The asset will be depreciated using a fiveminus−year recovery schedule. The existing equipment, which originally cost $25,000 and will be sold for $10,000, has been depreciated using an MACRS fiveminus−year recovery schedule and three years of depreciation has already been taken. The new equipment is expected to result in incremental before-tax net profits of $15,000 per year. The firm has a 40 percent tax rate. If Cuda does not buy the new asset, the old equipment will remain in service and be sold for $5,000 (after taxes) five years from now. How should financial analysts at Cuda take this information into account when evaluating the purchase of new equipment today? Question content area bottom Part 1 A. the $5,000 reduces the initial cash outlay required to purchase the new asset B. the $5,000 is irrelevant because if Cuda buys the new asset, it will sell the old equipment today for $10,000 and it will not sell it for $5,000 five years from now C. analysts should not try to account for this information because what the company will decide to do five years from now is too uncertain D. the $5,000 is an opportunity cost and should be treated as a cash outflow in the year 5 project cash flow estimates for the new asset

1. Your recently completed well is producing 42.0°API oil and 0.856 specific gravity gas at 1000 scf/STB. Producing gas-oil ratio has remained constant, so you believe reservoir pressure is above the bubble-point pressure of the reservoir oil. 1) Estimate bubble-point pressure given that reservoir temperature is 205°F. 2) Estimate values of solution gas-oil ratio at pressures below bubble-point pressure for the reservoir oil. Start at a pressure of 2500 psig and decrease pressure in 1000 psi increments to a final pressure of 500 psig. 3) Estimate values of oil formation volume factor at pressures below bubble-point pressure for the reservoir oil. Start at a pressure of 2500 psig and decrease pressure in 1000 psi increments to a final pressure of 500 psig. 4) Estimate a value of the coefficient of isothermal compressibility for use at 4000 psia for the black oil. 5) Estimate a value of the coefficient of isothermal compressibility at 2000 psia.
