“We are very pleased to receive this recognition once again, as a reflection of our commitment to patients, local communities, society and the planet,” said Daniel O’Day, Chairman and Chief Executive Officer, Gilead Sciences. “Corporate responsibility is inherent in everything Gilead does, as we work toward our vision of making the world a healthier place for all people.”

The DJSI World applies a transparent, rules-based constituent selection process based on the companies’ S&P Global ESG Score resulting from the annual S&P Global Corporate Sustainability Assessment (CSA). The CSA consists of a rigorous questionnaire assessing both public and non-public data submitted by participating companies. This year, more than 10,000 publicly traded companies were invited to participate in the S&P Global CSA.
