Buffett refines plans for his fortune and donates more Berkshire shares

On Monday, Buffett said three potential successor trustees have been named to act if his daughter Susie, 71, and sons Howard, 69, and Peter, 66, are unable to do so.

Each successor trustee, he noted, is somewhat younger than his children, well known to them and “makes sense to all of us.”

Buffett also said he will donate about $1.14 billion of additional Berkshire stock to four family foundations.

The tycoon has donated 56.6% of his Berkshire shares to foundations and the Bill & Melinda Gates Foundation since pledging in 2006 to give almost all of his money to charity.

The donations totaled more than $58 billion at the time Buffett made them, including more than $43 billion to the Gates Foundation.

Buffett has run Berkshire since 1965.
