OUR PURPOSE PIONEERING SCIENCE ENVIRONMENT COMMUNITY REPORTING 66 ENABLING EMPLOYEES TO THRIVE BIOGEN 2021 YEAR IN REVIEW PATIENTS OUR PEOPLE Inspiring employee engagement Every day we passionately advance our purpose of serving humanity through science, embracing the responsibility that hundreds of thousands of people in more than 100 countries depend on Biogen’s therapies to make a meaningful difference in their lives. We strive to create a workplace where employees are motivated and supported, empowered to own their careers, and connected to resources that help them thrive. Around 2,300 employees globally are members of our nine Employee Resource Networks (ERNs), groups for those who share characteristics, life experiences and interests, along with their allies. These groups offer opportunities to support and advance business objectives, exchange knowledge, find mentors, volunteer and receive support – all invaluable for career development. In 2021, the ERNs and DE&I hosted more than 60 events, including holding our first global Week of Understanding. Biogen employees also launched a new ERN called the Parenting Network Group (PNG). PNG provides support, networking and development opportunities to working parents and caregivers. More than half of Biogen’s employees are working parents, and with family and work lives more blended than ever, PNG helps employees navigate the challenges of work-life balance. Together, we hope to help employees be more engaged and effective at work and happier at home. For years we’ve held an internal event called Science Day, which began primarily as an R&D-focused convening, with presentations that celebrated scientific advances across the company. Over time, we’ve made it more inclusive, both geographically and among functions across the company, including Medical, Pharmaceutical Operations & Technology and Manufacturing. In 2021, all of Biogen was invited to Science Day, which welcomed 2,100 employees and received extremely positive ratings. FEATURE Delivering on pay equity Our promise to our workforce and society is that employees will receive equal pay for equal work. To deliver, we conducted a global pay equity analysis, sharing the results with our employees in 2021. We found that 99.7% of employees were paid consistent with our compensation philosophy. For the remaining 0.3% of employees, we assessed their skill, level, experience and other factors, and made adjustments, as appropriate. Our approach validated that fairness and equity are embedded in our compensation practices. An external consultant helped us analyze comparable roles to evaluate whether gender impacted compensation. In the U.S., where the law permits the collection of racial and ethnic data, we also included race and ethnicity in the analysis, consistent with our commitment to racial and ethnic equity. We will continue to hold ourselves accountable, regularly reviewing our compensation practices and analyzing the equity of compensation decisions, for individual employees and our workforce as a whole. If we identify employees with pay disparities, we review and take appropriate action to ensure fidelity between our stated philosophy and actions. We chose to examine pay equity rather than only looking at pay gap. Gender pay gap is the difference between the average pay of all males in an organization and average pay of all females in an organization; whereas pay equity is the difference in pay between a male and a female performing an equivalent role within an organization. In the countries where we are required legally to conduct a pay gap analysis, we do so. Conducting a global pay equity analysis is just one part of our overall commitment to equity. We strive to pay employees equitably within a reasonable range, taking into consideration factors such as role; function; market data; internal equity; job location; relevant experience; and individual, business unit and company performance. We will continue to regularly review our compensation philosophy; ensure employees understand the total compensation practices; and provide training for managers and leaders to prevent bias during hiring, compensation decisions and performance management. Our promise to our workforce and society is that employees will receive equal pay for equal work.
