Charlie Munger's wife, Nancy Munger, passed away early last year. She donated most of her stock holdings to a trust of which she and Charlie were the co-trustees. In accordance with Nancy Munger's will, Charlie disposed of 6,000 Berkshire Cl A shares (BRK.A) at the beginning of November. Yesterday, Munger reported that he donated 25 shares of Berkshire Hathaway stock  to the Henry E. Huntington Library and Art Gallery. The dollar value of the donation is close to $3 million. After this transaction Charlie Munger owns 6,403 BRK.A shares. Charlie Munger also owns 750 BRK.B shares. The total value of his Berkshire Hathaway stock holdings is $765 million, just a fraction of what Warren Buffett owns (see Warren Buffett's stock picks).
