Marina Syltus, chief financial officer of Worcester Water Treatment, wants to know the cost of the company’s capital so it can make wiser budgeting decisions. Syltus has assembled the following data:- Worcester’s long-term debt has a market value of $230 million.
- Worcester’s shares have a total market value of $782 million.
- The marginal tax rate is 37%.
- The required return on equity is 14.6%.
- Worcester’s long-term debt has a weighted average interest rate of 9.4%.
To calculate the weighted average cost of capital, Syltus needs: A)
| the required return on debt. |
| B)
| the target debt/equity ratio. |
| C)
| both the required return on debt and the target debt/equity ratio. |
|
The equation for the weighted average cost of capital is as follows:
Market value of debt / market value of debt and equity × required return on debt × (1 − tax rate) + market value of equity / market value of debt and equity × required return on equity.
As such, we need the required return on debt to determine the WACC. However, analysts normally assume debt and equity are at their target ratio to calculate the cost of capital. If the current capital allocation does not match the target weighting, we use the target weighting. Thus, we also need the target weights for debt and equity, which we can derive from a target debt/equity ratio. |
