ACE Ltd Board To Recommend 33% Quarterly Dividend Increase

ZURICH, Switzerland – 18 November, 2011 – The Board of Directors of ACE Limited (NYSE: ACE) announced that it will recommend to shareholders a 33% increase in the company’s quarterly dollar-denominated dividend, from $0.35 per share to $0.47 per share. The company will file a proxy statement with the Securities and Exchange Commission, which will be mailed to shareholders of record as of November 30, 2011.

“We are pleased to propose to our shareholders a substantial increase to the dividend, which reflects our full confidence in ACE’s strong balance sheet and earnings generation power,” said Evan G. Greenberg, Chairman and Chief Executive Officer, ACE Limited. “The increased dividend payout provides an attractive cash return for our shareholders particularly in this current low interest rate environment and represents a modest impact to capital, so preserving our considerable capital flexibility for risk and growth opportunities both now and into the future. We believe this action furthers our commitment to creating exceptional shareholder value.”

“As part of our continuous review of ACE’s overall capital management needs and plans, we determined an increase to our dividend was warranted at this time,” said Philip V. Bancroft, Chief Financial Officer, ACE Limited. “This action is a one-time increase that resets the level of our annual dividend. We reassess our dividend every year and intend to continue our longstanding practice of steady dividend increases.”

The resolution to increase the dividend would be an amendment to the existing dividend resolution as approved by the company’s shareholders on May 18, 2011, and would apply to the next two quarterly dividend installments. An extraordinary general shareholder meeting to vote on the resolution will take place on Monday, January 9, 2012, at the company’s offices in Zurich. The Board also declared that the first of such installments shall be payable on January 31, 2012, to shareholders of record at the close of trading on the New York Stock Exchange on January 10, 2012. In the event shareholders reject the proposed increase, the dividend would continue to be paid in the originally approved amount.
