Shrieves Casting Company is considering adding a new line to its product mix, and the capital budgeting analysis is being conducted by Sidney Johnson, a recently graduated MBA. The cost of new machinery for the new product line would be $644,000. The machinery has economic life of eight years, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the machine. The new line would generate incremental sales of 70,000 units per year at variable cost per unit of $21 and fixed cost of $725,000 per year. Each unit can be sold for $37 in the first year. The sale price and cost are both expected to remain the same. The firm’s tax rate is 35 percent, and the rate of return required for this type of investment is 15 percent.

1. Calculate the base-case cash flow and NPV.
2. Calculate the accounting break-even point.
3. What is the sensitivity of NPV to changes in the sales quantity? What is the effect on NPV of a 500-unit decrease in projected sales.
4.   Suppose the projections given for price, quantity, variable costs, and fixed costs are all

        accurate to within +/-10 percent. Calculate the best-case and worst-case NPV.
