Impact of the Tohoku Pacific Earthquake on the NKSJ Group

As those affected by the Tohoku Pacific Earthquake of March 11, 2011, work to recover, the NKSJ Group expresses its heartfelt sympathy and solidarity. Following is a summary of how the NKSJ Group has been affected so far.

1. Impact of the Disaster on Operations

Some buildings and equipment of NKSJ Group companies in disaster affected areas have sustained damage or been otherwise affected. Operations have been suspended at some branches and offices in affected areas of NKSJ Group insurance companies Sompo Japan Insurance Inc., Nipponkoa Insurance Co., Ltd., Saison Automobile & Fire Insurance Co., Ltd., and Sompo Japan Himawari Life Insurance Co., Ltd.

2. Impact on Financial Results

The NKSJ Group’s insurance companies have set up response headquarters and implemented other response measures, and are currently handling inquiries and accident reports associated with damage resulting from the earthquake.

The Group is currently investigating what impact, if any, the earthquake will have on its financial results and will immediately release a revised earnings forecast for the current fiscal year if necessary in light of the investigation’s outcome.
