1 2 3 BTN 137 Assume that Alibaba Group decides to launch a new website to market discount bookkeeping services to consumers. This chain, named Aladin, requires $500,000 of startup capital. The founder contributes $375,000 of personal assets in return for 15,000 shares of common stock, but he must raise another $125,000 in cash. There are two alternative plans for raising the additional cash. Plan A is to sell 3,750 shares of common stock to one or more investors for $125,000 cash. Plan B is to sell 1,250 shares of cumulative preferred stock to one or more investors for $125,000 cash (this preferred stock would have a $100 par value, an annual 8% dividend rate, and be issued at par). If the new business is expected to earn $72,000 of aftertax net income in the first year, what rate of return on beginning equity will the founder earn under each alternative plan? Which plan will provide the higher expected return? If the new business is expected to earn $16,800 of aftertax net income in the first year, what rate of return on beginning equity will the founder earn under each alternative plan?
