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 at least once a year.

Materiality Assessment and Stakeholder Communication

ASEH has adopted GRI Universal Standards 2021, AA 1000 Stakeholder Engagement Standard (SES), Impact Valuation Methodology and Responsible Business Alliance’s (RBA) Validated Audit Program (VAP) as to conduct materiality assessment every year. These standards allow the company to develop an impact-oriented materiality analysis framework to identify major sustainability issues. In addition, we have incorporated major sustainability topics with Enterprise Risk Management (ERM), that enables us to identify sustainability risks, and integrate them into the sustainability management process.

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 2022 Sustainability Report, we collected the feedback of 2,642 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, a 176-member team including subgroup CSC members led by ASEH senior executives in identifying the importance of each sustainability issue with regard to our company operations. We selected 16 major issues which are the same as the selected issues for last year 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 20 issues that are related to ASEH’s sustainability issues. Compared with the previous year, we added “Biodiversity” issue.

7 Economic Issues, 6 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.

In line with global sustainability reporting standards, ASEH uses the step-by-step guidance provided in the GRI 3: Material Topics 2021, to determine material topics based on stakeholder concerns, organizational and operational impact, and economy, environment and people impacts. We consolidate and analyze stakeholder concerns through daily communication and surveys and seek out opinions from internal and external experts. On the organizational and operational impact, and economy, environment and people impacts, we adopt the double materiality concept from the Draft European Sustainability Reporting Standards to assess the impact of sustainability issues within and outside of the organization. The management and the team are invited to evaluate the impact of sustainability issues on the company's operations, focusing on the operational benefits linked to financial performance. On the economy, environment and people impacts, ASEH performs a comprehensive impact valuation assessment annually and references the results of the RBA VAP to determine the significance of external impacts and decide on the gravity of sustainability issues.

2,642 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 2,642 stakeholders' responses. Respondents include employees (1,473), customers (115), shareholders (30), suppliers/contractors (717), government (70), industry unions/associations (33), and community (incl. NGOs, Media) (204).

176 CSC Members

Integrating ESG (Environmental, Social and Governance) into the company's core operations is a key driver for ASEH's corporate sustainability. A 176-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.

4 Impacts - Economic, Environmental, Social and Tax

We adopt the Total Impact Measure and Management framework, Natural Capital Protocol and the Social Capital Protocol, to express top sustainability impacts in monetary values.

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).

16 Key Issues

The CSC initially identified 16 material issues that are of importance to stakeholders, of impact to the company’s sustainable development and of impacts on the economy, environment and people. After further deliberation, the assessment ultimately yielded 16 issues of materiality and these issues were reported to the board of directors. Consequently, the material issues form the basis for the disclosures in the 2022 Sustainability Report and formulating internal sustainable management goals.

21 Sub-topics

A further 21 sub-topics (18 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 long-term sustainability goals, and are monitoring and measuring the completion rates of such goals at regular intervals.

40 Long-term Goals

To elevate the impact of corporate sustainability, we have made commitments to various major issues and formulated 40 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 member companies hold internal CSCs to manage and track the progress and sustainability trends.
