Corporate GovernanceBasic Policies on Corporate Governance

Basic Policies

In line with its Management Philosophy, MS&AD, as a holding company overseeing all group businesses, has established a transparent management framework that incorporates internal checking functions. The Company's objectives are to sustain consistent growth over the long term by using corporate resources efficiently and managing risks properly and ultimately, to further increase corporate value.

Corporate Governance Structure

As a company whose operations are reviewed by corporate auditors, MS&AD is working to improve corporate governance in large part by reinforcing the functions of the Board of Directors and Board of Corporate Auditors, and through the active disclosure of information.
MS&AD has introduced an executive officer system and is strengthening the control of MS&AD management by clarifying the roles of the Board of Directors, who are responsible for management decision-making and supervision, and the Executive Officers, who are responsible for business execution. Moreover, MS&AD believes that in order to reinforce the management monitoring and supervision functions, and thereby making the management highly transparent, it is crucial to incorporate perspectives independent of the management. Consequently, 4 of the 13 members on the Board of Directors and 3 of the 5 Corporate Auditors are selected from outside. In addition, the Board of Directors has two internal committees: the Nomination Committee and Remuneration Committee, which are chaired by outside directors who also account for the majority of the members.

Management structure for group business

MS&AD has a business management agreement with its directly invested insurance subsidiaries (Mitsui Sumitomo Insurance Co., Ltd., Aioi Nissay Dowa Insurance Co., Ltd., Mitsui Direct General Insurance Co., Ltd., Mitsui Sumitomo Aioi Life Insurance Co., Ltd., Mitsui Sumitomo Primary Life Insurance Co., Ltd.) to provide business administrative support.

MS&AD believes that obtaining timely and accurate information regarding the business of its subsidiary companies is beneficial to the smooth operations of the group. Therefore, MS&AD board members concurrently serve as directors of the subsidiary companies. Furthermore, directors from the subsidiary companies participate in Group Management Committees depending on the topic.

MS&AD also has a business management agreement with each of its directly invested affiliated business companies to do business administration and management of them as the parent company.
