This document discusses dividend policy and cash distribution to shareholders. It begins by explaining the different ways firms can distribute cash, namely through cash dividends, share repurchases, or reinvesting in the company. It then discusses the dividend irrelevance proposition put forth by Modigliani and Miller that the choice of distribution does not affect firm value. However, it notes that taxes, transactions costs, and the information conveyed by dividends make dividend policy important for firms and shareholders.
