The Filtration Experts Co. is looking at replacing its existing manufacturing machine with a new machine that is more efficient. The new machine has an installed cost of $450,000. This new machine is depreciated at a declining balance CCA rate of 20%, has a 6 year life, and can be sold for $100,000 at the end of its life. The new machine will save the firm $105,000 per year in operating costs, and the system requires an initial investment in net working capital of $30,000 that will be recovered at the end of the project. The existing machine today has a market value of $125,000, and would be expected to have a salvage value of $25,000 at the end of 6 years. The corporate tax rate is 37 percent and the discount rate is 12 percent, should the project be accepted
