Basically, CEOs have five essential choices for deploying capital—investing in existing operations, acquiring other businesses, issuing dividends, paying down debt, or repurchasing stock—and three alternatives for raising it—tapping internal cash flow, issuing debt, or raising equity. Think of these options collectively as a tool kit. Over the long term, returns for shareholders will be determined largely by the decisions a CEO makes in choosing which tools to use (and which to avoid) among these various options.
