McGilla Golf has decided to sell a new line of golf clubs. The clubs will sell for $740 per set and have a variable cost of $340 per set. The company has spent $144,000 for a marketing study that determined the company will sell 56,000 sets per year for seven years. The marketing study also determined that the company will lose sales of 8,900 sets of its high-priced clubs. The high-priced clubs sell at $1,040 and have variable costs of $640. The company will also increase sales of its cheap clubs by 10,400 sets. The cheap clubs sell for $380 and have variable costs of $200 per set. The fixed costs each year will be $9,040,000. The company has also spent $1,050,000 on research and development for the new clubs. The plant and equipment required will cost $28,280,000 and will be depreciated on a straight-line basis. The new clubs will also require an increase in net working capital of $1,240,000 that will be returned at the end of the project. The tax rate is 40 percent, and the cost of capital is 10 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.) (Negative amounts should be indicated by a minus sign. Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.)
