A firm has a three divisions, Division 1, Division 2, and Division 3. Divisions 1 and 2 represent 32% and 22% of the firm's value, respectively. The firm's WACC is 8.5%, Division 1's WACC is 9.6%, and Division 2's WACC is 6.6%. 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 3.8%, and the Market Risk Premium is 6.9%, what is the WACC of Division 3?
