The value of diversity in corporate America cannot be overstated. Whether in the boardroom or on a retail sales floor, a diverse pool of people brings unique perspectives, original ideas, and an edge factor that can help any business create out-the-box solutions. Still, despite mounds of research underscoring the value of hiring people from different backgrounds, a recent study by the Financial Times found that older white men comprise the majority of the boards of directors at U.S. companies. According to U.S. board composition: male, stale and frail?, the average board member is 62 years old and has served for nearly a decade. In turn, African Americans are not being heard and included in boardrooms when important decisions regarding a company's operations, CEO appointment, and compensation policies are being made. This applies to Netflix, PayPal, eBay, Yahoo, Inc. and a list of other companies that do not have an African American seated on their boards. Along with calling out corporations for excluding blacks in their boardrooms, Black Enterprise is also spotlighting prominent African American executives and retirees who serve as corporate directors at companies across the nation. Here is a list of 10 black men and women using their expertise to provide insight and oversight at widely recognized household brand-name companies.
