Gator Fabrics Inc. currently has zero debt (i.e., wd = 0). It is a zero growth company, and
additional firm data are shown below. Now the company is considering using some debt,
moving to the new capital structure indicated below. The money raised would be used to
repurchase stock at the current price. It is estimated that the increase in risk resulting from
the additional leverage would cause the required rate of return on equity to rise somewhat,
as indicated below. If this plan were carried out, by how much would the WACC change,
i.e., what is WACCOld − WACCNew?
