IRR. The Michener Company purchased a special machine 1 year ago at a cost of $12,000. At that time, the machine was estimated to have a useful life of 6 years and no disposal value. The annual cash operating cost is approximately $20,000.

                A new machine that has just come on the market will do the same job but with an annual cash operating cost of only $17,000. This new machine costs $15,000 and has an estimated life of 5 years with no disposal value. The old machine could be used as a trade-in at an allowance of $5,000. Straight-line depreciation is used and the company’s income tax rate is 40 percent. Compute the internal rate of return on the new investment.
