ate of $8\%$ a year. A flotation cost of $13\%$ would be required to issue new common stock. Gao's preferred stock sells for $$32\mathrm{.}97,$ pays a dividend of $$3\mathrm{.}90$ per share, and new preferred stock could be sold with a flotatior

ost of $9\%.$ The firm has outstanding bonds with $25$ years to maturity, a $9\%$ annual coupon rate, semiannual payments, and $$1,000$ par value. The bonds are trading at $$908\mathrm{.}72.$ The tax rate is $25\%.$ The market risk

remium is $7\%,$ the risk$-$free rate is $7\mathrm{.}5\%,$ and Gao's beta is $1\mathrm{.}3.$ In its cost$-$of$-$capital calculations, Gao uses a target capital structure with $50\%$ debt, $15\%$ preferred stock, and $35\%$ common equity.
