Determining TransUnion regularly collects feedback from internal and external stakeholders to determine our ESG priorities. In 2021, we refreshed our ESG materiality assessment ESG to prioritize the ESG issues most important to our stakeholders. Materiality The assessment process started with a gap analysis and industry benchmarking, as well as a review of international sustainability frameworks and ratings, including the SASB, TCFD, GRI, UN SDGs, and frequently cited ESG ratings. We surveyed and interviewed 36 internal and external stakeholders, including employees, investors, customers, NGOs and industry experts. We leveraged the insights from these different perspectives to develop our materiality matrix. We are committed to periodically refreshing our materiality assessment to ensure our program continues to align with the quickly evolving sustainability landscape.
