Board composition We believe an effective board consists of a diverse group of individuals who bring a variety of complementary skills and a range of personal and business experience to their positions. The collective experience of our directors covers a wide range of geographies and industries, including health care and clinical practice, insurance, consumer products, technology, capital markets and financial services, and roles in academia, corporate governance, government, intergovernmental organizations and business leadership. The board’s diversity is considered in the director nomination process and assessed annually when the board evaluates overall effectiveness. We are committed to actively seeking women and racially/ethnically diverse director candidates. Upon the election of the 2022 director nominees, our board will be 25% female independent directors and 38% racially/ ethnically diverse independent directors. Our directors may serve on three other public company boards and our CEO may serve on one other public company board. We strive to maintain a balance of tenure on the board. Long-serving directors bring valuable experience with our company and familiarity with the successes and challenges the enterprise has faced over the years, while newer directors contribute fresh perspectives. Independent board leadership is another important component of our governance structure. We separate the positions of CEO and chair, and our bylaws require the company to have either an independent chair of the board or a lead independent director.
