A company is considering two mutually exclusive expansion plans. Plan A requires a $39 million expenditure on a large-scale integrated plant that would provide expected cash flows of $6.23 million per year for 20 years. Plan B requires a $13 million expenditure to build a somewhat less efficient, more labor-intensive plant with an expected cash flow of $2.91 million per year for 20 years. The firm's WACC is 9%. a.
