McGilla Golf is evaluating a new line of golf clubs. The clubs will sell for $1,070 per set and have a variable cost of $485 per set. The company has spent $175,000 for a marketing study that determined the company will sell 54,000 sets per year for seven years. The marketing study also determined that the company will lose sales of 10,200 sets of its high-priced clubs. The high-priced clubs sell at $1,570 and have variable costs of $700. The company also will increase sales of its cheap clubs by 12,800 sets. The cheap clubs sell for $485 and have variable costs of $215 per set. The fixed costs each year will be $10,000,000. The company has also spent $1,350,000 on research and development for the new clubs. The plant and equipment required will cost $33,600,000 and will be depreciated on a straight-line basis to a zero salvage value. The new clubs also will require an increase in net working capital of $2,740,000 that will be returned at the end of the project. The tax rate is 24 percent and the cost of capital is 14 percent. Suppose you feel that the values are accurate to within only 10 percent. What are the best-case and worst-case NPVs? (Hint: The price and variable costs for the two existing sets of clubs are known with certainty, only the sales gained or lost are uncertain.) (A negative amount should be indicated by a minus sign. Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.) Best-case Worst-case
