Companies can redistribute their war chests to shareholders by issuing larger or special dividends, or more commonly through share buyback operations. Companies do this because if actually held in cash, the companies will be earning a low rate of return in the money markets, whereas they could be using the funds to invest in more profitable projects. If they continue not to invest the funds, shareholders may sell the company's shares and make it vulnerable to a takeover. This would place the current management's jobs at risk.
