The remaining book value is being strait line depreciated to 0 salvage value, at the rate of $20,000/year. The new machine costs $400,000. If introduced, the company estimates that will save annually $60,000 on a before tax basis. This is considered a yearend cash flow. The corporate tax rate is 40%; discount rate used is 15%. The new machine will be straight line depreciated on ten year life to 0 salvage value. In order to encourage the replacement of the old machine the state Environmental Protection Agency is offering a replacement subsidy. This is paid one year after the replacement.
