Agreement between Mitsui Sumitomo Insurance Company, Limited, and Aioi Nissay Dowa Insurance Company, Limited, regarding functional reorganization - Aiming at Becoming a World-leading Insurance and Financial Group -

Following their business integration on April 1, 2010, MS&AD Insurance Group Holdings, Inc. (Mr. Toshiaki Egashira, President) (Hereafter known as "MS&AD Holdings" or "the Holding Company), Mitsui Sumitomo Insurance Company, Limited (Mr. Yasuyoshi Karakawa, President) (Hereafter known as "Mitsui Sumitomo Insurance"), and Aioi Nissay Dowa Insurance Company, Limited (Hisahito Suzuki, President) (Hereafter known as "Aioi Nissay Dowa Insurance") have deliberated the reorganisation of the insurance companies under the umbrella of the Holding Company and today, based on the assumption that approval will be obtained from of the concerned authorities, they have reached an agreement to reorganize their various functions as of April 1, 2014.

I. The aim of functional reorganization 1. Functional reorganization focused on 'A structure that realizes our target business group'

Market shrinkage caused by the decreasing birthrate and aging population and a succession of large-scale natural disasters and slumps in the financial markets over recent years have meant that the business environment for the insurance industry has become very tough. Another major problem is how to respond to the diversification of customer needs and sales methods, and changes to regulations on domestic and foreign markets.
After the inauguration of the MS&AD Group in April, 2010, we took the first step towards a business merger by advancing the merger of Aioi Insurance Company, Limited, and Nissay Dowa Insurance Company, Limited, and the merger of Mitsui Sumitomo Kirameki Life, Limited, and Aioi Life Insurance Company, Limited, in order to improve the business efficiency of the management of the group. They are also responding to system integration, the biggest task facing the merger, by steadily advancing preparations that include starting up agent systems for full operation in the 2013 fiscal year.
For the second step in the merger, we continuously considered the reorganization of the insurance companies under the umbrella of the Holding Company (Mitsui Sumitomo Insurance and Aioi Nissay Dowa Insurance. Hereafter known as "the Two Core Non-life Insurance Companies"), and consequently decided to reorganize the group by functions to achieve the following goals.
1) Improve entire group enterprise value: 'Growth' and 'Efficiency' across entire group
2) Respond to diverse customer needs: Utilise merits of the Two Core Non-life Insurance Companies
3) Strengthen group governance: Strengthen governance system centered on the Holding Company
Due to the revised Insurance Business Law that will be implemented in April, 2013, there will be a transfer of insurance contracts and a review of the regulations which enables the recommission of insurance sales. Based on the system review, the style of this functional reorganization will be like nothing before.

2. Clarifying the business concept and how to utilise the synergy of the Two Core Non-life Insurance Companies

Mitsui Sumitomo Insurance and Aioi Nissay Dowa Insurance pursued strength and efficiency in their respective business domains, exerted themselves to improve their competitiveness and established an unshakeable presence.
The functional reorganization will clarify the business concept between the Two Core Non-life Insurance Companies, strengthen their respective business foundations more than ever, and utilize efficient management to increase their earning power.
(1) Mitsui Sumitomo Insurance will utilise this comprehensive strength to provide superior products and services and will evolve into global insurance and financial services, both in domestic and foreign markets.
(2) Aioi Nissay Dowa Insurance will strengthen its relationship with its unique partner Toyota Group/Nippon Life Group and capitalize on these merits to deliver superior products and services and develop into a region-based business. Furthermore, their development into foreign markets will focus on the continued retail business from Toyota dealers.
The aim for the domestic insurance business is to improve management efficiency through the reorganization of business and sales channels and integrate the common company functions into the Holding Company, etc, hereby optimizing the group's functions.
Clarifying the business concept and optimizing the companies' functions will concentrate the merits of the Two Core Non-life Insurance Companies, capitalize on their synergy, increase the support and satisfaction we gain from our customers, and move us closer to the unassailable position of Japan's No.1 Insurance Group.

II. Description of Functional Reorganization 1. Reorganization of business projects and sales channels

1) Hull, cargo, as well as aviation insurance will move to Mitsui Sumitomo Insurance.

Of these contracts, in regards to hull and cargo insurance, product supply functionality will be unified within Mitsui Sumitomo Insurance; and at Aioi Nissay Dowa Insurance, they will receive product supplies from Mitsui Sumitomo Insurance and sell it by recommission. Also, regarding aviation insurance, employees of Aioi Nissay Dowa Insurance will be seconded to Mitsui Sumitomo Insurance and will work together on the sales of said insurance. By carrying out the above, Mitsui Sumitomo Insurance will enhance its position in regards to hull, cargo plus
aviation insurance; moreover, it will exhibit its comprehensive strength as a member of the Group by further utilizing strength in the corporate market.
In the business market it will make further use of its strength and exhibit its overall ability.
