East-West Cable, inc., is considering the purchase of new data transmission equipment. Estimated annual cash revenues for the new equipment are $1 million, and operating costs (including depreciation of $400,000) are $825,000. The equipment costs $2 million, it has a five-year life, and it will have no residual value at the end of the five years. Compute the payback period for the piece of equipment. Does this method yield a positive or a negative response to the proposal to buy the equipment if the company has set a maximum payback period of four years?
