As for the future of the Bill and Melinda Gates Foundation, while the pair have said they plan to continue working together, CEO Mark Suzman recently revealed that the former couple reached an agreement in which Melinda will step down if, after two years, either she or Bill decides they can no longer work together. "In such a case, Melinda would receive personal resources from Bill for her philanthropic work," Suzman said. "These resources would be completely separate from the foundation's endowment, which would not be affected."
