(1) Beneficial owners exercise both sole voting and sole investment power unless otherwise stated. Class A Stock is convertible into thirty shares of Class B Stock at the option of the shareholder. As a result, pursuant to Rule 13d-3(d)(1) of the Securities Exchange Act of 1934, a shareholder is deemed to have beneficial ownership of the shares of Class B Stock which such shareholder may acquire upon conversion of the Class A Stock. In order to avoid overstatement, the amount of Class B Stock beneficially owned does not take into account such shares of Class B Stock which may be acquired upon conversion (an amount which is equal to 30 times the number of shares of Class A Stock held by a shareholder). The percentage of outstanding Class B Stock is based on the total number of shares of Class B Stock outstanding as of March 3, 2000 (5,385,320 shares) and does not take into account shares of Class B Stock which may be issued upon conversion of Class A Stock. 

(2) Includes 474,998 shares owned directly and beneficially by Warren E. Buffett, and 2,168 shares owned by three trusts of which Mr. Buffett is sole trustee but with respect to which Mr. Buffett disclaims any beneficial economic interest. Mr. Buffett shares investment and voting power with respect to 34,478 Class A shares and 21 Class B shares owned by Susan T. Buffett 

(3) Mr. and Mrs. Buffett have entered into a voting agreement with Berkshire providing that, should the combined voting power of shares held by Mr. and Mrs. Buffett and the trusts exceed 49.9% of Berkshire's total voting power, they will vote those shares in excess of that percentage proportionately with votes of the other Berkshire shareholders.
