11 – 13 WACC and target weights After careful analysis, Dexter Brothers has deter-
mined that its optimal capital structure is composed of the sources and target
market value weights shown in the following table.

The cost of debt is estimated to be 7.2%; the cost of preferred stock is estimated
to be 13.5%; the cost of retained earnings is estimated to be 16.0%; and the cost
of new common stock is estimated to be 18.0%. All of these are after-tax rates.
The company’s debt represents 25%, the preferred stock represents 10%, and
the common stock equity represents 65% of total capital on the basis of the mar-
ket values of the three components. The company expects to have a significant
amount of retained earnings available and does not expect to sell any new com-
mon stock.
