Materiality and KPI

Materiality

Process for Identifying Material Issues​

TOA CORPORATION identifies social issues by referencing international standards such as ISO 26000 and the SDGs, surveys by external ESG rating agencies, and communication with stakeholders. Among the issues considered highly important and relevant both to society (stakeholders) and to the Company, we have specified five priority items as material issues (materiality) requiring focused action. In addition, to respond to changes in risks and opportunities stemming f rom shifts in the social environment, we review our material issues once a year.​
