As much as billionaire couple Bill and Melinda Gates want to keep their pending divorce private, the split is already sending shockwaves through the worlds of philanthropy and public health. The Bill and Melinda Gates Foundation has an endowment of nearly $50 billion and donates about $5 billion annually to causes around the world. In a statement following the Gates’ divorce announcement on Twitter, the foundation said they would remain co-chairs and trustees and that no changes in the organization were planned. Experts note any changes that might happen because of the split would be incremental, but some worry the divorce might affect the foundation’s future plans.
