(Calculating IRR, payback, and a missing cash flow) The Merriweather Printing Company is trying to decide on the merits of constructing a new publishing facility. The project is expected to provide a series of positive cash flows for each of the next four years. The estimated cash flows associated with this project are as follows: (Click on the icon in order to copy its contents into a spreadsheet.) If you know that the project has a regular payback of 2.4 years, what is the project's IRR? The IRR of the project is \%. (Round to two decimal places.) (Related to Checkpoint 11.1 and Checkpoint 11.4) (Calculating NPV, PI, and IRR) Fijisawa, Inc. is considering a major expansion of its product line and has estimated the following cash flows associated with such an expansion. The initial outlay would be $10,700,000, and the project would generate cash flows of $1,290,000 per year for 20 years. The appropriate discount rate is 9.5 percent. a. Calculate the NPV. b. Calculate the PI. c. Calculate the IRR. d. Should this project be accepted? Why or why not? a. The NPV of the expansion is $. (Round to the nearest dollar.)
