Formula sheet Note: No further explanation will be given for these formulas at the examinations. Student should know what each variable stands for. Sustainable growth rate (Covered in Ch.3) g = p (1 - d )(1 + D E ) T - p (1 - d )(1 + D E ) Alternative formulas for sustainable growth rate (Covered in Ch.3) If ROE is deﬁned as the ratio of the current year’s net income to the previous year’s equity g = ROE × (1 - d ) If ROE is deﬁned as the ratio of the current year’s net income to the current year’s equity g = ROE × (1 - d ) 1 - ROE × (1 - d ) Growing annuity (Covered in Ch. 5) PV = n X t =1 C (1 + g ) t - 1 (1 + r ) t = C " 1 - ( 1+ g 1+ r )
