an express dog food delivery service based in Frankfurt is considering changing its capital structure. its capital structure is as follows: it has 2000 5% annual coupon 10 year bonds outstanding which currently trade at 85. the book value for these bonds is 2.0 million. its common stock sells at $20 per share with 200,000 shares issued and outstanding . its par value is 5.00 per share and 400,000 shares are authorized. its common stock has a book value o $23 per share.

it has a current beta of 0.8. the risk free rate is 4.5%, the market rate of return is 11.0%. there is no preferred stock outstanding and there are no plans to issue preferred stock. it is subject to a 40% marginal income tax rate.

its investment bank say its optimal capital structure should be at 50% debt,50% equity. at this level of debt, the cost of debt would be 6%. this level of debt will of course change its stock beta and result in a different cost of equity.

f. what will its new after tax cost of debt be?

g. what will its new cost of equity be?
