1. Qualitative Information on Current Quarterly (Interim) Financial Statements

(1) Qualitative Information on Consolidated Operating Results

During six months ended September 30, 2010, Japanese economy saw signs of economic upturn which could be seen in corporate profitability improvements along with recovery in equipment investment and individual consumption. However, overall conditions remained severe as recent environment grew serious and also unemployment rate hovering at a high rate.

Under the management conditions, business results of the Group for the six months ended September 30, 2010, were as follows:

As a result of underwriting income of 1,599.1 billion yen (including net premiums written of 1,301.6 billion yen), investment income of 112.3 billion yen, and other ordinary income of 9.6 billion yen, ordinary income reached 1,721.1 billion yen. Ordinary expenses were 1,650.6 billion yen, including underwriting expenses of 1,363.3 billion yen (including net claims paid of 783.8 billion yen), investment expenses of 34.7 billion yen, operating expenses and general and administrative expenses of 249.7 billion yen, and other ordinary expenses of 2.8 billion yen.

(2) Qualitative Information on Consolidated Financial Condition

Total assets as of September 30, 2010 increased by 3,853.5 billion yen versus the end of the previous consolidated accounting year to 11,373.2 billion yen due to reasons such as Aioi Insurance Co., Ltd. and Nissay Dowa General Insurance Co., Ltd. etc. became consolidated subsidiaries of the Company. Net assets increased by 385.3 billion yen versus the end of the previous year, to 1,696.4 billion yen, reflecting the increase of capital surplus after share exchanges with Aioi Insurance Co., Ltd. and Nissay Dowa General Insurance Co., Ltd.

(3) Qualitative Information on Consolidated Earnings Forecasts

The full-year consolidated earnings forecast calls for ordinary income of 3,360.0 billion yen, ordinary profits of 71.0 billion yen, and net income of 40.0 billion yen. Note that, in light of mid-term consolidated results and the outlook going forward, we have revised the forecast figures previously announced on May 20, 2010.

The key assumptions behind the earnings forecast are as follows:

• Forecast for net premiums written is based on proprietary forecasting, taking into consideration past trends and other factors.

• We expect net claims (the total of net claims paid and provision for outstanding claims) related to natural disasters of 4.0 billion yen and 3.0 billion yen (Note 2), respectively, to be generated by our subsidiaries, Mitsui Sumitomo Insurance Co., Ltd. and Aioi Nissay Dowa Insurance Co., Ltd. (Note 1).

• We expect extraordinary loss of up to approximately 36.0 billion yen due to business integrations cost which is mainly cost for merger of Aioi Insurance Co., Ltd. and Nissay Dowa General Insurance Co., Ltd.

• We are assuming that there will not be a significant fluctuation in interest rates, exchange rates, or stock markets after the end of September, 2010.

• While our earnings forecast is based on the above assumptions, actual earnings may differ significantly from this forecast given the possibility of a natural disaster the magnitude of which exceeds our assumptions and other factors.

(Note) 1. Aioi Insurance Co., Ltd. and Nissay Dowa General Insurance Co., Ltd. merged together as of October 1, 2010, and formed a new merged company, Aioi Nissay Dowa Insurance Co., Ltd.

2. The figure includes the results of the Nissay Dowa General Insurance Co., Ltd. for the six months ended September 30, 2010.

Solvency Margin Ratio

Domestic insurance companies calculate solvency margin ratio based on Ministry of Finance Notification No. 50, dated 1996 and on Articles 86 and 87 of the Ordinance for Enforcement of the Insurance Business Law.

Insurance companies provide for reserves to cover payment of insurance claims for covered risks. However, it is essential to maintain sufficient capacity to enable payment even when risks exceeding those normally foreseen occur, such as the occurrence of a major disaster or a large decline in the price of assets held by the insurance company.

It is the solvency margin ratio ((C) in the table below) that serves as an indicator of the capacity to pay the “Total amount of risk” ((B) in the table below), which expresses risks exceeding those normally foreseen, with capital, reserves, and other funds held by the insurance company (namely, the total amount for the solvency margin ((A) in the table below). This ratio is calculated based on the Insurance Business Law and other related laws.

The solvency margin ratio is one objective measure used by administrative authorities in monitoring insurance companies.

The company is deemed to have sufficient capacity to pay insurance claims and other expenses if the ratio is 200% or higher.

An annualized premium for a single-payment policy is the premium divided by the number of years of coverage.

2.		“Medical coverage, living benefits, etc.” shows the portion of annualized premiums that corresponds to medical coverage benefits (for hospitalization, surgeries, etc.), living benefits (for specified diseases, nursing care, etc.), and premium waiver benefits (excluding those for disability, but including those for specified diseases, nursing care, etc.)
