Twelve more of America’s wealthiest families committed to giving the majority of their wealth to philanthropy by taking the Giving Pledge, bringing the total number of pledge signatories to 81. Initiated by Warren Buffett and Bill and Melinda Gates in June 2010, the Giving Pledge is a long-term charitable initiative that aims to inspire conversations about philanthropy and increase charitable giving in the United States.

Among the twelve, Edgar M. Bronfman, president of the Samuel Bronfman Foundation.

About: The Giving Pledge does not involve direct appeals, pooling money or requirements to support a particular cause or organization. The goal is to encourage an open conversation, learn from each other, get smarter about giving and ultimately to change the norms around wealth and giving.
