Question 2: 15 Marks)

Century Lab plans to purchase a new centrifuge machine for its Manitoba facility. The machine costs

$137,500 and is expected to have a useful life of eight years, with a terminal disposal value of

$37,500. Savings in cash operating costs are expected to be $31,250 per year. However, additional

working capital is needed to keep the machine running efficiently. The working capital must

continually be replaced, so an investment of $10,000 needs to be maintained at all times, but this

investment is fully recoverable (will be "cashed in") at the end of the useful life. Century Lab's

required rate of return is 14%. Ignore income taxes in your analysis. Assume all cash flows occur

at year-end except for initial investment amounts.
