The T. H. King Company has introduced a new product line that requires two work centers, A and B for manufacture. Work Center A has a current capacity of 10,000 units per year, and Work Center B is capable of 12,500 units per year. This year (year 0), sales of the new product line are expected to reach 10,000 units. Growth is projected at an additional 1,000 units each year through year 5. Pre-tax profits are expected to be $30 per unit throughout the 5-year planning period. Two alternatives are being considered: 1) Expand both Work Centers A and B at the end of year 0 to a capacity of 15,000 units per year, at a total cost for both Work Centers of $200,000; 2) Expand Work Center A at the end of year 0 to 12,500 units per year, matching Work Center B, at a cost of $100,000, then expanding both Work Centers to 15,000 units per year at the end of year 3, at an additional cost at that time of $200,000. The King Company will not consider projects that don't show a 5th year positive net present value using a discount rate of 15%. What are the pre-tax cash flows for the two alternatives compared to the base case of doing nothing for the next five years, and what action, if any, should the company take?

Pre-tax profits are expected to be $5 per test throughout the 5-year planning period. Two alternatives are being considered: 1) Expand both Test Centers A and B at the end of year 0 to a capacity of 2,000 units per week, at a total cost for both Test Centers of $300,000; 2) Expand Test Center A at the end of year 0 to 1,500 units per week, matching Test Center B, at a cost of $100,000, then expanding both Test Centers to 2,000 units per year at the end of year 3, at an additional cost at that time of $250,000.
