Marbella, Inc. plans to purchase new equipment for its manufacturing plant for a total cost of $500,000. The equipment will be depreciated to a salvage value of $100,000 over 4 years and is expected to be sold for its salvage value at the end of year 4. In addition, Marbella plans to immediately purchase $5,000 of new spare parts for the machinery in the plant. What terminal cash flow (TCF) should Marbella use in year 4 of its capital budgeting analysis if the project is expected to last 4 years?
