Solution
Hover or tap a marked figure, like 72,000, to see how it is made and where else it appears.
The model. Walter holds that dividend policy affects the value of the share, and that the optimum policy depends on the relationship between the firm's rate of return on investment (r) and its cost of capital, the return shareholders require (k). The share's value is
P = [D + r(E − D) ÷ ke] ÷ ke,
where D is the dividend per share and E the earnings per share.
Determining the optimum payout
- Growth firm (r > k): retained earnings earn more than shareholders require, so the firm should retain its earnings; the optimum payout is zero, which maximises the value of the share.
- Declining firm (r < k): shareholders gain if the earnings are distributed; the optimum payout is 100%.
- Normal firm (r = k): the dividend policy does not affect the value of the share; there is no optimum payout.
Assumptions. Investment financed only by retained earnings; constant r and k; constant earnings and dividends; a perpetual life. The model is criticised because firms do use external finance and r and k change as investment grows, so its "all or nothing" optimum is a guide rather than a rule.
