1. Calculating Payback [LO2] What is the payback period for the following set of cash flows? Year Cash Flow 0 -$8,300 1 2,100 2 3.000 3 2,300 4 1,700 2. Calculating Discounted Payback [LO3] An investment project has annual cash inflows of $2,800, $3,700, $5,100, and $4,300, for the next four years, respectively. The discount rate is 11 percent. What is the discounted payback period for these cash flows if the initial cost is $5.200? What if the initial cost is $6,400? What if it is $10,400? 3. Calculating AAR (LO4] You're trying to determine whether to expand your business by building a new manufacturing plant. The plant has an installation cost of $13.5 million, which will be depreciated straight-line to zero over its four-year life. If the plant has projected net income of $1,570,000, $1,684,200, $1,716,300, and $1,097,400 over these four years, respectively, what is the project's average accounting return (AAR)? 4. Calculating NPV (LO1] For the cash flows below, suppose the firm uses the NPV decision rule. At a required return of 11 percent, should the firm accept this project? What if the required return is 24 percent? , Year Cash Flow 0 -$34.000 1 15,000 2 17.000 3 13,000 5. Calculating NPV and IRR [LO1, 5] A project that provides annual cash flows of $11,700 for nine years costs $63,000 today. Is this a good project if the required return is 8 percent? What if it's 20 percent? At what discount rate would you be indifferent between accepting the project and rejecting it? 6. Comparing Investment Criteria (L01, 2, 3.5, 7] Consider the following two mutually exclusive projects Year Cash Flow (A) Cash Flow (B) 0 -$364.000 -$52.000 1 46,000 25,000 2 68,000 22.000 3 68,000 21,500 458,000 17.500 Whichever project you choose, if any, you require a return of 11 percent on your investment. 1. If you apply the payback criterion, which investment will you choose? Why? 2. If you apply the discounted payback criterion, which investment will you choose? Why? 3. If you apply the NPV criterion, which investment will you choose? Why 4. Based on your answers in (a) through (c), which project will you finally choose? Why
