Hubbards Pet Foods is financed 60% by common stock and 40% by bonds. The expected return on the common stock is 11.7%, and the rate of interest on the bonds is 6.3%. Assume that the bonds are default-free and that there are no taxes. Now assume that Hubbards issues more debt and uses the proceeds to retire equity. The new financing mix is 36% equity and 64% debt. Assume the debt is still default free.
