Of the 1415 companies listed on the 25 African stock exchanges, we screened for those companies with revenue of $100 million or more, or a market cap of $150 million or more, which yielded a list of 602 companies. The public websites of these 602 companies were reviewed to identify female C-suite executives. Our team of researchers then examined the list of these women to determine those who have a title of chief executive officer or managing director or president AND have bottom line profit and loss responsibility. This resulted in the final Definitive List of women CEOs.
