As a dividend focused investor who also owns BRK I see no reason or urgency to changing the policy on dividend payments.  BRK offers investors an ultra low cost means of investing in some of the worlds largest companies including access to private companies.  Those companies churn out billions in cash flow to BRK which in turn has done a pretty good job of reinvesting the cash on behalf of the shareholder.  As an added benefit the process is pretty tax efficient for the shareholder (particularly those in Canada)  as there is no dividend income to be taxed at your marginal tax rate and the future gains will be taxed at about half that rate.

If BRK is no longer able to find those investment opportunities I would fully endorse a change in dividend policy.
