You are considering changing the capital structure of the target firm after five years. How much would this increase the value of the target by?

Current WACC = 10%

New WACC = 8%

PV of cashflows of first five years = $149

You expect the cashflows to grow at 3% every year after year five.

CF6=$43.

Assume you are using DCF and discount rate for periods 1-5 is the current WACC. (You aren't changing the structure until then.)
