In the spring of last year, QM Industries' management is evaluating the purchase of a new plant. To finance the purchase, QM would offer 20-year bonds with a par value of RM1,000 and an interest rate of 6% per year, paid semiannually, at a price of RM1,020. Preferred stock with a dividend of RM2.50 can be sold for RM35. QM's common stock is currently trading at RM50 per share. The firm paid a RM4 dividend last year and expects dividends to grow at a rate of 4% per year in perpetuity.
