Under Hamada's Equation for beta......

- the unlevered beta represents the optimal point where the weighted average cost of capital is minimized

- the levered beta will rise as the firm takes proportionately more debt financing relative to equity financing

- taxes do not impact the levered beta

- As E increases, the levered beta increases

- the only time levered beta and the unlevered beta are equal is when the firm is financed with virtually 100% debt
