Christie's Train Shoppe has 15,000 shares of common stock outstanding at a current price of $11 a share. It also has 2,000 shares of preferred stock outstanding at a price of $34 a share. There are 50 bonds outstanding that have a 7.5 percent semiannual coupon. The bonds mature in 6 years, have a face value of $1,000, and currently sell at 96 percent of par. (Christie's does not have a target capital structure, so the market values of the capital components are used instead.) What is the capital structure weight of their preferred stock?
