USA FCC Information Concerning Radio Frequency Interference This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. [. . . ] To compute the net future value (NFV), press #. To compute the payback discounted over time (DBP), press #. The DBP value appears. Cash Flow Worksheet 45 Computing IRR and MOD 1. The IRR variable and current value are displayed (based on the current cash-flow values). To compute the internal rate of return, press %. To select the reinvestment rate (RI), press #. Key in the reinvestment rate value and press !. To compute the modified internal rate of return, press #. The calculator displays the MOD value. When solving for IRR, the calculator performs a series of complex, iterative calculations that can take seconds or even minutes to complete. The number of possible IRR solutions depends on the number of sign changes in your cash-flow sequence. · When a sequence of cash flows has no sign changes, no IRR solution exists. The calculator displays Error 5. · When a sequence of cash flows has only one sign change, only one IRR solution exists, which the calculator displays. · When a sequence of cash flows has two or more sign changes: ­ ­ At least one solution exists. As many solutions can exist as there are sign changes. When more than one solution exists, the calculator displays the one closest to zero. Because the displayed solution has no financial meaning, you should use caution in making investment decisions based on an IRR computed for a cash-flow stream with more than one sign change. 46 Cash Flow Worksheet The time line reflects a sequence of cash flows with three sign changes, indicating that one, two, or three IRR solutions can exist. · When solving complex cash-flow problems, the calculator might not find PB, DPB, IRR, and MOD, even if a solution exists. In this case, the calculator displays Error 7 (iteration limit exceeded). Example: Solving for Unequal Cash Flows These examples show you how to enter and edit unequal cash-flow data to calculate: · · · · · · Net present value (NPV) Net future value (NFV) Payback (PB) Discounted payback (DPB) Internal rate of return (IRR) Modified internal rate of return (MOD) A company pays $7, 000 for a new machine, plans a 20% annual return on the investment, and expects these annual cash flows over the next six years: Year Purchase 1 2­5 6 Cash Flow Number CFo C01 C02 C03 Cash Flow Estimate -$7, 000 3, 000 5, 000 each year 4, 000 As the time line shows, the cash flows are a combination of equal and unequal values. As an outflow, the initial cash flow (CFo) appears as a negative value. Cash Flow Worksheet 47 Entering Cash-Flow Data To Select Cash Flow worksheet. Enter cash flows for years two through five.
