Stakeholder Communication


We define stakeholders as a group or an organization that can affect or be affected by ASEH. Based on the 5 major principles (dependency, responsibility, influence, diverse perspective, tension) of the AA1000 Stakeholder Engagement Standard (SES), we have identified 7 major categories of stakeholders. They are categorized into two groups based on whether the impact is direct or indirect. Our direct stakeholders include shareholders, employees, customers, and suppliers/contractors; our indirect stakeholders include community (incl. NGOs, media), government and industry unions/associations.

We engage with our stakeholders through a variety of means, depending on the nature of the relationship. The methods of engagement will vary depending on the stakeholders, the issues of concern and the purpose of engagement. We regularly report the stakeholder communication status to the board of directors every year.

Materiality Assessment

To ensure effectiveness in communicating the company’s sustainability information disclosures, ASEH has adopted the GRI Standards, AA 1000 Stakeholder Engagement Standard (SES) and AA1000 AccountAbility Principles as the benchmark for developing the materiality analyses framework, and identifying major sustainability issues. In addition to applying these principles to compile non-financial reports, they are also used as a basis for ASEH to formulate long-term sustainability objectives and strategies. For the 2021 ESG Report, we collected the feedback of 2,638 stakeholders to gain insight into their level of attention to our efforts in addressing sustainability issues. To measure the effects that sustainability issues have on our company operations, our CEO led our senior executives and CSC members (totaling 189 members) in identifying the importance of each sustainability issue with regard to our company operations. We selected 16 major issues to be prioritized in driving corporate sustainability and setting long-term sustainability targets.

To identify relevant and important issues, ASEH referenced international standards & regulations, sustainable investment ratings and industry peers as well as stakeholder communications. We collected and organized 19 issues that are related to ASEH’s sustainability issues. Compared with the previous year, we added “Data and Privacy” and “Work from Home” issues.

7 Economic Issues, 5 Environmental Issues, 7 Social Issues

International standards and regulations:
GRI Standards, SASB, SDGs, RBA

Sustainability Investment Assessment:
DJSI, CDP, MSCI ESG Index, FTSE4Good Emerging Index

Global semiconductor industry:
Benchmarking sustainability policies and practices from semiconductor companies listed on the DJSI index

Stakeholder Engagement:
Analysis of online media reports and regular/occasional stakeholder communication to evaluate stakeholders' perception on sustainability issues

We follow guidelines from GRI Standards to rate the importance of issues based on the level of stakeholder concern and the effect on the operations of the organization. ASEH collects stakeholder concerns through its routine communication and the use of questionnaires. Senior management are empowered to determine the level of importance and relevance of these findings based on the respective impact to their organizations.

2,638 Stakeholders

The degree of concern from stakeholders is a key factor in determining the significance of a particular issue. ASEH has designed a questionnaire on sustainability that drew a total of 2,638 stakeholders' responses. Respondents include employees (1,326), customers (184), shareholders (42), suppliers/ contractors (795), government (53), industry unions/associations (18), and community (incl. NGOs, Media) (220).

189 CSC Members

Integrating ESG (Environmental, Social and Governance) into the company's core operations is a key driver for ASEH's corporate sustainability. A 189-member team of senior management leaders and CSC members participate actively in evaluating the impact of each sustainability topic on the company's revenues, risks, customer satisfaction and employees’ organizational identification, and ranking the level of each topic's importance according to the impact.

According to our materiality analysis results, the use of GRI themes and indicators as a basis allowed us to determine our stakeholders’ needs and disclosure preferences in regard to sustainability information. Additionally, we made efforts to enhance the transparency of sustainability issues (in relation to their policies, organization, practice, results and objectives, etc.) on different communication platforms (e.g., non-financial reports, annual reports, and websites). Compared with the previous year, we added “Diversity and Inclusion” as key issue.

16 Key Issues

The CSC initially identified 16 material issues that are of importance to stakeholders and of impact to the company’s sustainable development. After further deliberation, the assessment ultimately yielded 16 issues of materiality that form the basis for the disclosures in the 2021 ESG report and formulating internal sustainable management goals.

22 Sub-topics

A further 22 sub-topics (19 GRI-specific and 3 ASEH-specific) for disclosures were derived from the 16 issues. Other topics of lower priority will also be concurrently disclosed in the report.

Commitment is key to demonstrating influence in corporate sustainability. As such, we have set longt-erm sustainability goals, and are monitoring and measuring the completion rates of such goals at regular intervals.

39 Long-term Goals

To elevate the impact of corporate sustainability, we have made commitments to various major issues and formulated 39 long-term sustainability goals for 2030. In addition, we have promoted and implemented various projects at our factories worldwide year by year.

4 Committees

Every year, the CSC assesses the progress of goal completion via the reports presented by colleagues from relevant business units. On a regular basis, our three major subsidiaries hold internal CSCs to manage and track the progress and sustainability trends.
