In analyzing a new potential business MacDonald Publishing's financial staff is estimating an initial capital expenditure of $5 million. This equipment will be depreciated according to the MACRS 3 year class life and will have a market value of $1 million after four years.

The new business is expected to have an economic life of four years and is expected teo generate annual sales of 5 million and incur operating costs (excluding depreciation) of 3 million annually.
