The Institute owns a controlling interest in American Century Investments, and through this amazing business model, our annual dividend payments ensure the ongoing support of important work that can improve human health and save lives. Since 2000, nearly $1.3 billion in dividends have been paid to the Institute. We view this unique ownership structure as the ultimate example of investing with impact. As we strive to deliver superior investment results for clients and they continue to entrust us with their assets, this success can impact basic medical research funding aimed at finding cures for life-threatening diseases.
