Evan G. Greenberg, Chairman and Chief Executive Officer of ACE Limited,
commented: “ACE had a good fourth quarter, which contributed to an excellent
year. Even with the impact of Superstorm Sandy, we produced over $490 million
of operating income and increased book value per share 2%. These results
continue to demonstrate the strength of our underwriting culture and balance
sheet, and the benefits of our globally diversified business.

“For the year, after-tax operating income was $2.6 billion, up 13% from 2011.
We produced $1.2 billion in underwriting income – an increase of 11% over
prior year – and a combined ratio of 93.9%. This is an excellent underwriting
result, particularly given the worst drought conditions in the U.S. in 25
years as well as the losses from Sandy. We also produced strong investment
results, with investment income down less than 3% – a good performance
considering record low interest rates. Our operating ROE was 11% and per share
book value grew 12% for the year, bringing three-year and five-year compounded
annual book value per share growth to 11.4% and 10.7%, respectively.

“Net premiums globally grew 6% for the year and in constant dollars – 9%
excluding our crop insurance business. Our premium revenue growth is
benefitting from an improved price environment in the U.S., our large and
growing business presence around the world in Asia, Latin America and Europe,
and our unique and balanced portfolio of insurance products including
commercial, specialty and personal P&C, personal accident and life. Insurance
pricing in the U.S. continues to improve and price increases are spreading to
more product classes – a trend that has continued into the first quarter. With
low interest rates pressuring industry returns, we expect this orderly and
rational trend of price increases to continue. For our company, a continued
focus on underwriting discipline, enhanced through the use of portfolio
management and data analytics, is contributing significantly to both our
premium growth and underwriting profitability, and we expect this discipline
will continue to make a notable difference in our results going forward.”

^(2) Non-GAAP Financial Measures:

Operating income or income excluding net realized gains (losses), net of tax
is a common performance measurement for insurance companies. We believe this
presentation enhances the understanding of our results of operations by
highlighting the underlying profitability of our insurance business. We
exclude net realized gains (losses) and net realized gains (losses) included
in other income (expense) related to partially-owned entities because the
amount of these gains (losses) is heavily influenced by, and fluctuates in
part according to, the availability of market opportunities.

Underwriting income (loss) is calculated by subtracting losses and loss
expenses, policy benefits, policy acquisition costs and administrative
expenses from net premiums earned. We use underwriting income and operating
ratios to monitor the results of our operations without the impact of certain
factors, including net investment income, other income (expense), interest and
income tax expense and net realized gains (losses). Life underwriting income
includes net investment income and gains (losses) from fair value changes in
separate account assets that do not qualify for separate account reporting
under generally accepted accounting principles (GAAP). P&C underwriting income
and consolidated underwriting income are non-GAAP financial measures. We
believe the use of these measures enhances the understanding of our results of
operations by highlighting the underlying profitability of our insurance
business.

Operating effective tax rate is a non-GAAP financial measure. The numerator
excludes tax on net realized gains (losses). The denominator excludes net
realized gains (losses), before tax.

Operating return on equity (ROE) or ROE calculated using income excluding net
realized gains (losses) is an annualized non-GAAP financial measure. The ROE
numerator includes income adjusted to exclude net realized gains (losses), net
of tax. The ROE denominator includes the average shareholders' equity for the
period adjusted to exclude unrealized gains (losses) on investments, net of
tax. To annualize a quarterly rate, multiply by four. Annualized ROE
calculated using income excluding realized gains (losses) is a useful measure
as it enhances the understanding of the return on shareholders' equity by
highlighting the underlying profitability relative to shareholders' equity
excluding the effect of unrealized gains and losses on our investments.

Book value per common share is shareholders' equity divided by the shares
outstanding.

Tangible book value per common share is shareholders' equity less goodwill and
other intangible assets divided by the shares outstanding.

See reconciliation of Non-GAAP Financial Measures on pages 21-22 in the
Financial Supplement. These measures should not be viewed as a substitute for
net income, return on equity, or effective tax rate determined in accordance
with GAAP.

^(3) The book value amounts reflect the effects of new accounting guidance for
deferred acquisition costs that is retrospectively applied to periods prior to
January 1, 2012. Refer to the Financial Supplement page 1 for further detail.
