Bill & Melinda Gates Foundation
January 2006 — Present
In 2006, I pledged most of my fortune to the Bill & Melinda Gates Foundation and to four charitable trusts created by my family. My gift to the Bill & Melinda Gates Foundation of 10 million shares of Berkshire Hathaway Inc. stock, to be paid in annual installments, was worth approximately $31 billion in June 2006. In 2010, I established The Giving Pledge with Bill and Melinda Gates. The Giving Pledge is an effort to help address society’s most pressing problems by inviting the world’s wealthiest individuals and families to commit to giving more than half of their wealth to philanthropy or charitable causes. We are inspired by the example set by millions of people who give generously (and often at great personal sacrifice) to make the world a better place.
