Chubb Estimates Losses from April and May Catastrophes;
Will Announce Second Quarter Earnings on July 21

FOR IMMEDIATE RELEASE

     WARREN, New Jersey, June 20, 2011 – The Chubb Corporation [NYSE: CB] announced today that it estimates aggregate losses from catastrophes for the months of April and May 2011 were approximately $250 million to $310 million before tax (approximately $0.55 to $0.68 per share after tax). Losses during the two month period were primarily related to tornadoes and severe storms in the United States. The impact of these catastrophes will be reflected in Chubb’s second quarter 2011 financial results. Chubb had previously disclosed in its Form 10-Q for the quarter ended March 31, 2011 that its estimated catastrophe losses for the month of April 2011 were between $175 million to $225 million before tax.

     Chubb expects to release second quarter 2011 earnings on Thursday, July 21, 2011 after the close of the market. The press release and financial supplement will be available shortly thereafter on Chubb’s website at www.chubb.com.

     A conference call will take place on the same day, Thursday, July 21, 2011 at 5:00 p.m. Eastern Daylight Time hosted by Chairman, President and CEO John Finnegan and other members of senior management. The call will be broadcast live over the Internet. To listen to the conference call log on to Chubb’s website at www.chubb.com and click on the microphone icon. If you are unable to listen to the live webcast, a replay of the call will be available through Friday, August 19, 2011 on Chubb’s website at www.chubb.com approximately two hours following the webcast.
