2. Explanation of revisions

The ordinary income forecast was revised upward primarily because Tokio Marine Financial Life Insurance Co., Ltd. expects to account for a reversal of underwriting reserves.*2
The ordinary profit and net income forecasts were revised downward primarily because of expected losses, related to natural disasters, by overseas consolidated subsidiaries.*3

The Company's business forecasts for the fiscal year ending March 31, 2012 are now being prepared. Details are scheduled to be announced on November 18, 2011, along with the Company's business results for the six months ended September 30, 2011.

(Notes)

*2:	The reversal of underwriting reserves will not affect either ordinary profit or net income since the amount to be accounted for will be equivalent to expected losses on separate account primarily owing to the deterioration of domestic stock market.
*3:	The expected major impact is from losses related to a number of tornadoes which occurred in the United States in April and May 2011. However, expected losses related to Hurricane Irene, which hit the East Coast of the United States in August 2011, are not included in the revised forecasts.
