A firm has a three divisions, Division 1, Division 2, and Division 3. Divisions 1 and 2 represent 40% and 29% of the firm's value, respectively. The firm's WACC is 8.3%, Division 1's WACC is 9.4%, and Division 2's WACC is 5.5%. Neither the divisions, nor the firm as a whole have any debt or preferred stock (i.e.: their capital structures are pure equity). If the risk free rate is 2.9%, and the Market Risk Premium is 5.7%, what is the WACC of Division 3?
