Better Mousetraps has developed a new trap. It can go into production for an initial investment in equipment of $6 million. The equipment will be depreciated straight- line over 6 years but in fact, it can be sold after 6 years for $500,000. The firm believes that working capital at each date must be maintained at a level of 10% of next year's forecast sales. The firm estimates production costs equal to $1.50 per trap and believes that the traps can be sold for $4 each. Sales forecasts are given in the following table. The project will come to an end in 6 years when the trap becomes technologically obsolete. The firm's tax bracket is 40%, and the required rate of return on the project is 12%. 1 T Year: Sales (millions of traps) 0 0.00 2 0.60 3 1.00 4 1.00 5 0.60 6 0.20 0.50 a. What is project NPV?
