Initiatives on Material Issues

Identifying and Reviewing Materiality (Material Issues)

We recognize that the sustainability of society as a whole will always have a significant impact on our corporate activities in the future. That is why we identify high priority issues from the point of view of management. Once we have identified these material issues, we incorporate them into our business activities, and disclosed details and the results of our initiatives in our Sustainability report.
Initially, in the fiscal year ended March 2008, we identified nine material issues of the Group by conducting a material issue assessment based on the framework of the GRI Guidelines, a set of international guidelines that address sustainability reporting. In the fiscal year ended March 2016, we reorganized the items into seven. Later, in response to changes in the external environment and other factors, we updated them to ten items in the Medium-term Management Strategy announced in March 2020.
In addition, in the Medium-term Management Strategy FY2031 that was announced in February 2023, we employed the following selection process to identify key factors from various perspectives and arranged these elements along two axes, in terms of their importance for each stakeholder, and their degree of importance in relation to Our Commitment. Following extensive discussion on the importance of each key factor undertaken by the Strategic Management Committee and the Board of Directors, an order of priority was established, and we re-established the key themes for each material issue and the nature and objectives of initiatives for each key theme.
We review material issues and other matters every year to ensure that we can appropriately identify and respond to changes in the business environment and other factors in a timely and appropriate manner. In this renewal, we decided to integrate "material issues" and "sustainability issues," which were previously organized and reviewed separately, into one. In addition, we added "strengthening information security," " geopolitical and geoeconomic risks," and "financial risk" as new material issues considering their growing importance in recent years.

Strengthening information security

Information leakage due to cyber-attacks is a risk that could hinder the Group's competitiveness and business continuity. We will work to strengthen IT governance and prevent information leaks in order to establish a global standard IT infrastructure.

Geopolitical and geoeconomic risks

International conflicts, wars and terrorism, economic sanctions and trade barriers, and policy changes in various countries can have a significant impact on our business. In order to expand our business globally, we will take initiatives related to reviewing our overseas investment strategy, formulating BCPs, and creating a stable overseas procurement portfolio, while taking account of country risks.

Financial Risks

Corporate finances can be significantly affected by corporate working capital funding, investment losses, market fluctuations, and credit risk. To ensure financial soundness, we will work toward strengthening cash management, monitoring the business and financial conditions of affiliated companies, and having appropriate pension asset management.

Selection Process
STEP1.
Identification of issues
Extracted key factors from among those identified from the perspectives of ESG and sustainability in 2015 in light of information such as GRI indicators, the OECD Guidelines for Multinational Enterprises and SRI categories. We identify issues from the perspective of social, environmental and economic trends, trends in markets related to the Company, and initiatives undertaken by the Group to increase our corporate value in the medium- to long-term. We also consider international guidelines and principles when selecting elements of these issues.
STEP2.
Organization and assessment of issues
In addition to these elements of issues, we set two axes on which to rank our material issues, including those established in the previous fiscal year: the importance to our various stakeholders, and the importance in light of Our Commitment. After all of our Executive Officers and Directors have organized the issues and key themes, they are discussed from the perspective of their importance to our stakeholders and the Company.
STEP3.
Selection of issues
Material issues and key themes are revised and redefined, with priority given to issues that are ranked as “very high” or “high” on both axes.
STEP4.
Establishment of nature and objectives of initiatives
The nature and objectives of initiatives to address the redefined material issues and key themes are established. The progress and results of these initiatives are regularly disclosed. Review is conducted annually to identify factors such as changes in the business environment in a timely and appropriate manner, then take measures as required.
