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 production line would be set up in unused space in Shrieves main plant. The machinerys invoice price would be approximately $200,000, another $10,000 in shipping charges would be required, and it would cost an additional $30,000 to install the equipment. The machinery has an economic life of 4 years, and Shrieves has obtained a special tax ruling that places the equipment in the MACRS 3-year class. The machinery is expected to have a salvage value of $25,000 after 4 years of use.

The new line would generate incremental sales of 1,250 units per year for 4 years at an incremental cost of $100 per unit in the first year, excluding depreciation. Each unit can be sold for $200 in the first year. The sales price and cost are expected to increase by 3% per year due to inflation. Further, to handle the new line, the firms net working capital for each year would have to equal to 12% of next years sales revenues. The firms tax rate is 40%,and its discount rate is 10%.

Part A

1. Define incremental cash flow.
2. Should you subtract interest expense when calculating project cash flow?
3. Suppose the firm had spent $100,000 last year to rehabilitate the production line site. Should this cost be included in the analysis? Explain.
4. Now assume that the plant space could be leased out to another firm at $25,000per year. Should this be included in the analysis? If so, how?
5. Finally, assume that the new product line is expected to decrease sales of the firms other lines by $50,000 per year. Should this be considered in the analysis?
