That's recent, just as of the last couple months. Historically the children's foundations have been a sideshow and he's given the bulk of his wealth away to the Gates Foundation. You can see that from the dollar amounts: this year's gift to the children's foundations was 1M BRK-B shares (the equivalent of about $500M) to each, while he's given away a total of $66B, over 120x as much.
