Final answer:
The NPV of the cockroach eradicator project is calculated by projecting annual cash flows based on sales, costs, depreciation, and taxes, then discounting these cash flows at a 19% required return and subtracting the initial investments.
Step-by-step explanation:
To project the net present value (NPV) of the new cockroach eradicator system, we need to calculate the cash flows for each year and discount them back to present value terms using the required return rate of 19%. The NPV calculation involves revenue, costs, working capital, tax effects, depreciation, and the salvage value of equipment.
First, we calculate the annual revenue by multiplying the unit sales by the price per unit. Then we subtract both variable and fixed costs to determine earnings before interest and taxes (EBIT). Working capital requirements are 15% of the change in sales each year. We calculate depreciation using the capital cost allowance (CCA) rate of 20% on the equipment's initial cost. Taxes are then calculated at 35% of EBIT minus depreciation.
At the end of five years, the equipment will be sold for 20% of its initial cost, which must also be incorporated into the NPV calculation by adding the after-tax salvage value to the cash flow of Year 5. Finally, each year's cash flow is discounted to present value using the required return of 19%, and the NPV is the sum of these present values. The initial $23 million cost for equipment and $1.6 million in net working capital are subtracted from the sum of discounted cash flows to determine the final NPV.
