All of the following statements are correct, except:

The firm's optimum debt/equity mix minimizes the firm's cost of capital, which in turn helps the firm to maximize shareholder wealth

A firm's mix of debt and equity used to finance its assets is not the firm's capital structure.

A non-optimal capital structure with either too much or too little debt leads to higher financing costs, and the firm will likely reject some capital budgeting projects that could have increased shareholder wealth with an optimal financing mix.

A project's NPV represents the increase in shareholders' wealth from undertaking a project; thus, a lower weighted average cost of capital gives higher project net present values and results in higher levels of shareholder wealth.
