Stakeholder Engagement

Stakeholder Engagement

As we progress towards corporate sustainability, TSMC places great importance on the expectations and demands of internal and external stakeholders. As such, TSMC has established a framework for ESG disclosure in compliance with the latest AA 1000 Accountability Principle issued in 2018. The framework is established on the four major principles of Inclusivity, Materiality, Responsiveness, and Impact. Each year, TSMC regularly evaluates stakeholder feedback and ESG trends through diverse communication channels. We also continue to conduct materiality analysis to identify material ESG topics and establish long-term ESG targets, adopt action plans, and track ESG progress and efficacy accordingly. GRI Standards are also adopted by TSMC as the enduring standard for identifying material issues within TSMC. We have integrated ERM (enterprise risk management) to assess the trends and impact of risks posed by material ESG issues, explain to the public how TSMC is mitigating risks, and build a resilient organization capable of thriving under changing global landscapes.

Phase I: Inclusivity Phase II: Materiality Phase III: Responsiveness Phase IV: Impact Define Major Stakehold-ers 1 Identify Sustainability Issues 2 Decide Disclosure Boundaries 6 Review Disclosed Content 7 Assess Level of Interest 3 Analyze Impact on Operations 4 Formulate Long-term Goals 8 Evaluate Impact 9 Map the Materiality Matrix 5 In compliance with the AA 1000 SES (Stakeholder Engagement Standards, SES), TSMC regards the following six stakeholders as the major stakeholders for engagement: employees, shareholders/investors, customers, suppliers/vendors, and government & society (community, academic institutions, media, NGO/NPO). By evaluating global sustainability trends and engaging with internal/external stakeholders, TSMC identified 21 ESG issues relevant to TSMC in 2020. In 2020, materiality analysis was conducted through surveys due to the COVID-19 pandemic. Each organization evaluated influential stakeholders that TSMC frequently engaged with, and issued ESG surveys to said stakeholders. We received 842 replies in 2020, and used the surveys to analyze their level of interest in ESG issues relevant to TSMC. The ESG Steering Committee, led by Chairman Mark Liu, and the ESG Committee Chairperson and Senior Vice President Lora Ho would spearhead efforts to analyze the impacts of each issue on operations (profitability, revenue, customer satisfaction, employee cohesion, risk) and review the sustainability roadmap for long-term development with a total of 150 colleagues that included TSMC's senior vice presidents, vice presidents, senior fab directors, and fab directors. The ESG Committee was able to identify 14 ESG issues as material based on materiality analysis in 2020. TSMC assessed each issues' impact on the boundaries of TSMC's value chain from supply chain and company operations to customers. Pursuant to GRI Standards, we have also identified 23 material topics specific to TSMC in alignment with the ESG issues and collected internal information, data, and management approaches for disclosure in compliance with reporting regulations. Corporate governance, risk management, ethics, regulatory compliance, economic performance, tax policies, and information security are seven issues classified under General Disclosures by the GRI Standards. While they will not be mapped in the materiality matrix, relevant information will be disclosed annually. TSMC has established 2030 targets for each material ESG issue. The ESG Committee will regularly review progress towards annual targets and formulate changes to the following year accordingly. Plans, progress, and changes will be disclosed in the annual CSR Report for external parties.
