ChipMOS Stakeholder

We define stakeholders as "internal and external groups or organizations that will affect or be affected by ChipMOS". Through the annual ESG Committee meeting, we gather the suggestions of all members, and discuss the same according to the Company's sustainability context, industrial characteristics and practical experience, and with reference to the five major principles of the AA1000 SES-2015 Stakeholder Engagement Standard (SES) (Dependence, Responsibility, Influence, Diverse Perspectives and Tension), and identify six types of stakeholders by voting: Shareholders, Customers, Employees, Suppliers, Government and Community groups.
