I’ve got a question with regards the calculation of Ke of Chrysos: the examiner calculated the Ke in a strange for me way:
Ke = 12·46% + [0·82 x (12·46% – 4·5%) x (0·2/0·8)]
Could you please kindly explain the formula examiner used here? what I got here: 12.46% must be the proxy’s ungeared Ke; 0.82 is (1-t); 0.2/0.8 is the Debt to equity. but the (12·46% – 4·5%) looks a bit strange for me.
