Final Report by the Special Advisory Committee(Japanese only)

In response to the Special Advisory Committee’s recommendations, ZHD will further promote and strengthen the initiatives that are already in place and implement new initiatives to strengthen the governance of the entire Group.

<Initiatives that are already in place> (Noted in the Secondary Report)
i) Establishment of the Data Governance Working Group
The Data Governance Working Group was established within the Risk Management Committee as a meeting body whereby those responsible for “research and development,” “data utilization,” and “security and privacy protection” jointly discuss the state of data governance and strengthen the aforementioned three areas in a well-balanced manner. The Working Group formulates the ZHD Group's data governance policy and rules, evaluates and audits each Group company's compliance with the said rules, recommends corrective actions, and takes other measures as necessary.

ii) Introduction of a “Three-Line Model”
In order to operate businesses in compliance with the rules set by the Data Governance Working Group, a “Three-Line Model” (three defensive lines) is introduced to the ZHD Group companies and each line is responsible for the following:
First Line: As risk owner, appropriately evaluates risks and controls the risks;
Second Line: Audits and evaluates the appropriateness of activities of the First Line, and provides advice to the First Line;
Third Line: Audits and evaluates the appropriateness of the activities of the Second Line, and provides specific advice for improvement if there are problems.
Based on this concept of the “Three-Line Model,” each ZHD Group company will implement a specific three-line governance system in a way that matches the actual situation of each company.


<Initiatives to be pursued in response to the recommendations received in the Final Report>
i) Establishment of “horizontal and vertical governance structure from the user’s perspective”
In addition to the implementation of the “Three-Line Model,” the ZHD Group will establish horizontal and vertical governance structures:
a) The horizontal governance structure will be established by strengthening the second line of governance in each company and will enable each company to achieve an autonomous governance structure that is in line with its business situation; and
b) Through the Data Governance Working Group, the vertical governance structure will achieve governance that is centralized across the entire Group and responds to the global business operating environment. ZHD will continuously report on the status of measures taken in ZHD and LINE Corporation (hereinafter “LINE”) to the Panel of Experts, etc., to be separately established by ZHD, and will ensure that the measures are implemented while receiving advice from the panel.

ii) Measures to be taken in individual areas to improve ZHD’s global data governance
Based on the recommendations of the Special Advisory Committee in the areas of: engagement with the public sector, economic security, security, privacy, risk management, and other individual areas, ZHD will take appropriate measures in a timely manner so that the Group companies will comply with NIST standards1 and protect not only personal information but also personal data2.
