The treasurer of Kelly bottling co (a corporation) currently has $240,000 invested in preferred stock yielding 8%. He appreciates the tax advantages of preferred stock and is considering buying $240,000 more with borrowed funds. The cost of the borrowed funds is 10%. He suggests this proposal to his board of directors. They are somewhat concerned by the fact hat the treasurer will be paying 2% more for funds than the company will be earning on the investments.
