Better Mousetraps has developed a new trap. It can go into production for an initial investment in equipment of $5.4 million. The equipment will be depreciated straight-line over 6 years to a value of zero, but in fact it can be sold after 6 years for $606,000. The firm believes that working capital at each date must be maintained at a level of 10% of next years forecast sales. The firm estimates production costs equal to $1.70 per trap and believes that the traps can be sold for $7 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 firms tax bracket is 35%, and the required rate of return on the project is 12%. Use the MACRS depreciation schedule.

Year:	0	1	2	3	4	5	6	Thereafter
Sales (millions of traps)	0	0.5	0.7	0.9	0.9	0.6	0.3	0

What is project NPV?

Note: Do not round intermediate calculations. Enter your answer in millions rounded to 4 decimal places.

By how much would NPV increase if the firm uses double-declining-balance depreciated with a later switch to straight-line when remaining project life is only two years?
