Principle 1.4 Policy for Strategic Equity Holdings

‹ MS&AD Insurance Group Basic Policy for Reduction of Strategic Equity Holdings ›

Strategic equity holdings is shares held under the assumption of long-term holding for the purpose of maintaining and strengthening comprehensive business relationships.
We have adopted a policy to reduce the aggregate amount of our strategic equity holdings, aiming to build a solid financial base less affected by fluctuations in stock prices and to improve the capital efficiency (Note).
The suitability of holding strategic equities is assessed from the perspective of the equity issuers’ growth potential and profitability for each equity and the medium- to long-term business relationship.
If the rationale is not confirmed, we shall proceed with sales of those strategic equity holdings after obtaining the equity issuers’ understanding. Otherwise, we may sell our holdings, taking into account the market environment and our business and financial strategies.


(Note) The Group's strategic equity holdings of JPY206.6 billion have been sold, in FY2022, exceeding the original plan of JPY100 billion (revised to JPY150 billion). The balance of the market value of the Company's strategic holdings as of 31 March 2023 is JPY 2,626.9 billion. The Group has increased the reduction plan from JPY 400 billion to JPY600 billion in the current The Medium -Term Management Plan (FY2022~FY2025) to improve capital efficiency. In the next The Medium-Term Management Plan, we aim to continue the same level of reduction and to reduce the market value of our strategic equity holdings by approximately half compare with the end of September 2022.

‹ Verification of propriety of strategic equity holdings and reduction efforts ›

  • Mitsui Sumitomo Insurance and Aioi Nissay Dowa Insurance shall examine the propriety of their strategic holdings by each equity based on profitability and balance of insurance contract as to whether the purpose of the holding is appropriate and whether the benefits and risks associated with the holding are commensurate with the capital cost. The results of these examinations shall be confirmed by MS&AD’s Board of Directors.
  • Based on the results of the examinations of each equity, constructive dialogue shall take place with regard to equities that do not meet the objective of the rationale and are particularly in need of improvement. The equity will continue to be held in the event that an improvement is anticipated, and sale negotiations will be entered into in the event that an improvement is not anticipated.
