Winterberry Corporation has $50 million in cash, 10 million shares outstanding, and a current share price of $30. Winterberry is deciding whether to use the $50 million to pay an immediate special dividend of $5 per share, or to retain and invest it at the risk-free rate of 10% and use the $5 million in interest earned to increase its regular annual dividend of $0.50 per share. Assume perfect capital markets.

(a) Suppose Winterberry pays the special dividend. How can a shareholder who would prefer an increase in the regular dividend create it on her own?

(b) Suppose Winterberry increases its regular dividend. How can a shareholder who would prefer the special dividend create it on her own?
