"We feel noble intentions should be checked periodically against results. We test the wisdom of retaining earnings by assessing whether retention, over time, delivers shareholders at least $1 of market value for each $1 retained. To date, this test has been met. We will continue to apply it on a five-year rolling basis. As our net worth grows, it is more difficult to use retained earnings wisely." Source: Berkshire Hathaway's Owner's Manual
Mr. Buffett:: "We will either pay large dividends or none at all if we can't obtain more money through re-investment (of those funds). There is no logic to regularly paying out 10% or 20% of earnings as dividends every year."
Charles Munger: "If you went to the leading schools, they wouldn't teach dividend policy this way." Source: My notes from the 2000 Berkshire Hathaway annual meeting
