Cold Goose Metal Works Inc, is a small firm, and several of its managers are worried about how soon the firm will be able to recover its initial investment from Project Sigma's expected future cash flows. To answer this question, Cold Goose's CFO has asked that you compute the project's payback period using the following expected net cash flows and assuming that the cash flows are received evenly throughout each year. Complete the following table and compute the project's conventional payback period. For full credit, complete the entire table. (Note: ound the conventional payback period to two decimal places. If your answer is negative, be sure to use a minus sign in your answer.) he conventional payback period ignores the time value of money, and this concerns Cold Goose's CFO. He has now asked you to ompute Sigma's discounted payback period, assuming the company has a 10% cost of capital. Complete the following table and perform ny necessary calculations. Round the discounted cash flow values to the nearest whole dollar, and the discounted payback period to two ecimal places. For full credit, complete the entire table. (Note: If your answer is negative, be sure to use a minus sign in your answer.) Shich version of a project's payback period should the CFO use when evaluating Project Sigma, given its theoretical superiority? The discounted payback period The regular payback period One theoretical disadvantage of both payback methods-compared to the net present value method-is that they fail to consider the alue of the cash flows beyond the point in time equal to the payback period. low much value in this example does the discounted payback period method fail to recognize due to this theoretical deficiency
