brks 14A filing discloses it this way, " Warren E. Buffett is Berkshire's Chief Executive Officer and Chairman of the Board of Directors. He is Berkshire's largest shareholder and owns shares of Berkshire that represent approximately 31.5% of the voting interest and 15.6% of the economic interest. As such he may be deemed to be Berkshire's controlling shareholder. It is Mr. Buffett's opinion that a controlling shareholder who is active in the business, as is currently the case and has been the case for Mr. Buffett for over 50 years, should hold both roles. This opinion is shared by Berkshire's Board of Directors.

Mr. Buffett and the other members of the Board of Directors extensively discuss succession planning at each meeting of the Board. Upon his death or inability to manage Berkshire, no member of the Buffett family will be involved in managing Berkshire but, as very substantial Berkshire shareholders, the Buffett family will assist the Board of Directors in picking and overseeing the CEO selected to succeed Mr. Buffett. At that time, Mr. Buffett believes it would be prudent to have a member of the Buffett family serve as the non-executive Chairman of the Board. Ultimately, however, that decision will be the responsibility of the then Board of Directors." I have no idea why VL changed the way they report, voting power?
