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. [. . . ] You must enter the number of occurrences (up to 9, 999), or frequency (F), for each additional cash flow (C01-C24). The calculator displays positive values for inflows (cash received) and negative values for outflows (cash paid out). Repeat steps 4 through 7 for all remaining cash flows and frequencies. To review entries, press # or ". To enter cash flows: Deleting Cash Flows When you delete a cash flow, the calculator decreases the number of subsequent cash flows automatically. Cash Flow Worksheet 43 The DEL indicator confirms that you can delete a cash flow. The cash flow you specified and its frequency is deleted. Inserting Cash Flows When you insert a cash flow, the calculator increases the number of the following cash flows, up to the maximum of 24. Note: The INS indicator confirms that you can insert a cash flow. Press # or " to select the cash flow where you want to insert the new one. The new cash flow is entered at C02. Computing Cash Flows The calculator solves for these cash-flow values: · Net present value (NPV) is the total present value of all cash flows, including inflows (cash received) and outflows (cash paid out). A positive NPV value indicates a profitable investment. 44 Cash Flow Worksheet · Internal rate of return (IRR) is the interest rate at which the net present value of the cash flows is equal to 0. Computing NPV 1. To compute the net present value for the series of cash flows entered, press %. Computing IRR 1. The IRR variable and current value are displayed (based on the current cash-flow values). The calculator displays the IRR 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. Cash Flow Worksheet 45 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. 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 IRR, 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) Internal rate of return (IRR) 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. 46 Cash Flow Worksheet Entering Cash-Flow Data To Select Cash Flow worksheet.
