Believing that when the pandemic is under control, people will want to pamper themselves a lot, Bessner's Sumptuous Spa is planning to expand its facilities, at an expected cost of $250 million. 10% of these required funds will be raised by issuing new preferred stock, and 25% will be raised by issuing new debt (bonds). Bessner's has $50 million available in retained earnings (internal equity} for this project, and the rest will have to be raised by issuing new external equity. Currently, bonds of this quality will have to be issued with 8% interest before tax. Bessner's preferred stock will be issued at $50 per share, paying a $7 per-share dividend to its buyers, and requiring a $5 flotation cost per share. New common stock can be issued at $28 per share, and is paying an expected dividend of $4 per share this year. Bessner expects the dividend to grow by 5% per year, and flotation costs for this new common stock will be $3 per share. Bessner's tax rate is currently 42%.
