ACE has grown considerably in past 23 years; Cayman

domicile was more suitable for smaller enterprise

Current domicile is incompatible with ACE as a major, global

NYSE-listed company with significant presence in the U.S.,

Europe, Asia and Latin America

Re-domicile reduces potential regulatory, political, financial

risks

Re-domicile increases strategic and capital flexibility with no

significant downside risks and little impact on business

operations

Why is ACE Limited re-domesticating?

Major financial center, home to many global financial and

insurance companies

Great stability –

political, economic and regulatory

A tradition of respecting the rule of law

Relatively sophisticated financial regulation

A network of excellent relations with major developed and

developing countries around the world

Reliable tax treaties

A centuries-old tradition of capitalism

Why re-domesticate to Zurich, Switzerland?

A highly reputable jurisdiction with an image that is more in

keeping with ACE

Enhanced corporate structure

Strategic flexibility

Predictable legal and tax environment

Costs little to nothing in net expense

No material change to effective tax rate

What are the benefits to the Company?

More shareholder-friendly jurisdiction: Swiss legal and

regulatory system well-established and respected

Financial reporting still in U.S. GAAP and in U.S. dollars

Shares still listed on NYSE

Dividend still paid in U.S. dollars

Increased shareholder rights:

Shareholder approval of capital changes and dividends

No poison pill

Shareholder pre-emptive rights
