ACE LTD - 10-Q - Management's Discussion and Analysis of Financial Condition and Results of Operations

August 01, 2012
SHARE THIS:

Edgar Online, Inc.
The following is a discussion of our results of operations, financial condition,
and liquidity and capital resources as of and for the three and six months ended
June 30, 2012.

All comparisons in this discussion are to the corresponding prior year periods unless otherwise indicated.


Our results of operations and cash flows for any interim period are not
necessarily indicative of our results for the full year. This discussion should
be read in conjunction with our consolidated financial statements and related
notes and our Management's Discussion and Analysis of Financial Condition and
Results of Operations included in our Annual Report on Form 10-K for the year
ended December 31, 2011 (2011 Form 10-K).

Effective January 1, 2012, we retrospectively adopted new accounting guidance
for costs associated with acquiring or renewing insurance contracts. Under the
new guidance, the definition of acquisition costs was modified to specify that a
cost must be directly related to the successful acquisition of a new or renewal
insurance contract in order to be deferred. Prior year amounts and ratios
contained in these consolidated financial statements have been adjusted to
reflect the impact of retrospective adjustments as a result of applying this new
accounting guidance.

In addition, effective January 1, 2012, we reclassified prior year segment
operating results in order to conform to certain organizational
realignments. These realignments resulted in a transfer of operating revenue and
underwriting results of our international direct-marketed and credit life
businesses from the Insurance - Overseas General segment to the Life segment.
These realignments have no impact on consolidated operating results; however,
prior year amounts and underwriting ratios contained in these consolidated
financial statements have been adjusted to conform to the current year
presentation.

Forward-Looking Statements


The Private Securities Litigation Reform Act of 1995 provides a "safe harbor"
for forward-looking statements. Any written or oral statements made by us or on
our behalf may include forward-looking statements that reflect our current views
with respect to future events and financial performance. These forward-looking
statements are subject to certain risks, uncertainties, and other factors that
could, should potential events occur, cause actual results to differ materially
from such statements. These risks, uncertainties, and other factors (which are
described in more detail elsewhere herein and in other documents we file with
the SEC) include but are not limited to:



• developments in global financial markets, including changes in interest

rates, stock markets, and other financial markets, increased government

involvement or intervention in the financial services industry, the cost

         and availability of financing, and foreign currency exchange rate
         fluctuations (which we refer to in this report as foreign exchange and
         foreign currency exchange), which could affect our statement of

operations, investment portfolio, financial position, and financing plans;

• general economic and business conditions resulting from volatility in the

         stock and credit markets and the depth and duration of recession;



• losses arising out of natural or man-made catastrophes such as hurricanes,

typhoons, earthquakes, floods, climate change (including effects on

weather patterns, greenhouse gases, sea, land and air temperatures, sea

         levels, rain and snow), nuclear accidents or terrorism which could be
         affected by:




  •   the number of insureds and ceding companies affected;




  •   the amount and timing of losses actually incurred and reported by insureds;




        •    the impact of these losses on our reinsurers and the amount and timing
             of reinsurance recoverable actually received;




        •    the cost of building materials and labor to reconstruct properties or
             to perform environmental remediation following a catastrophic event;
             and



• complex coverage and regulatory issues such as whether losses occurred

             from storm surge or flooding and related lawsuits;




     •   actions that rating agencies may take from time to time, such as financial
         strength or credit ratings downgrades or placing these ratings on credit
         watch negative or the equivalent;



• global political conditions, the occurrence of any terrorist attacks,

including any nuclear, radiological, biological, or chemical events, or

         the outbreak and effects of war, and possible business disruption or
         economic contraction that may result from such events;



• the ability to collect reinsurance recoverable, credit developments of

         reinsurers, and any delays with respect thereto and changes in the cost,
         quality, or availability of reinsurance;



• actual loss experience from insured or reinsured events and the timing of

         claim payments;



• the uncertainties of the loss-reserving and claims-settlement processes,

including the difficulties associated with assessing environmental damage

and asbestos-related latent injuries, the impact of

aggregate-policy-coverage limits, and the impact of bankruptcy protection

sought by various asbestos producers and other related businesses and the

         timing of loss payments;



• changes to our assessment as to whether it is more likely than not that we

will be required to sell, or have the intent to sell, available for sale

         fixed maturities before their anticipated recovery;




     •   infection rates and severity of pandemics and their effects on our
         business operations and claims activity;




     •   judicial decisions and rulings, new theories of liability, legal tactics,
         and settlement terms;

pricing or in policy terms and conditions, which may differ from our

         projections and changes in market conditions that could render our

• acquisitions made by us performing differently than expected, our failure

to realize anticipated expense-related efficiencies or growth from

acquisitions, the impact of acquisitions on our pre-existing organization

         consolidation of insurance and reinsurance brokers;




     •   material differences between actual and expected assessments for guaranty
         funds and mandatory pooling arrangements;



• the effects of investigations into market practices in the property and

         casualty (P&C) industry;




     •   changing rates of inflation and other economic conditions, for example,
         recession;




  •   the amount of dividends received from subsidiaries;



• loss of the services of any of our executive officers without suitable

         replacements being recruited in a reasonable time frame;




  •   the ability of our technology resources to perform as anticipated; and



• management's response to these factors and actual events (including, but

not limited to, those described above).

Net premiums written, which reflect the premiums we retain after purchasing
reinsurance protection, increased four percent in both the three and six months
ended June 30, 2012. In our Insurance - North American segment, retail premiums
grew primarily from new business opportunities, strong renewal retention,
increases in rates and exposure basis. This growth was partially offset by our
continued planned reductions in our U.S. general market risk transfer workers'
compensation business. The North American wholesale and specialty division grew
from increases in property, casualty and inland marine lines, partially offset
by lower agriculture premiums driven by reduced crop hail production. Our
Insurance - Overseas General segment reported an increase in international
retail premiums due to continued growth in our P&C and A&H lines of business.
This growth was partially offset by decreases in certain retail A&H production
in Combined's United Kingdom (U.K.) and Ireland regions. Combined Insurance
premiums continue to be hampered by the economic recession in its target
markets. Additionally, Combined's business in the U.K. and Ireland has been
impacted by changes in the regulatory environment as regulators in these two
countries have adopted a new stance regarding sales practices and customer
service. This has resulted in a need for us to re-evaluate our sales model and
to re-engineer our processes. We have put these two operations on a sales
moratorium while continuing to renew and service in-force policyholders. We have
decided to cease sales in our small Spanish branch indefinitely. We have
received regulatory approval to integrate all European operations of Combined
into our ACE European Group Limited subsidiary, incorporated in the U.K. We
expect to seek regulatory approval to re-commence sales in the U.K. and Ireland
in 2012. For the six months ended June 30, 2012, our Insurance - Overseas
General segment also benefited from the favorable impact of reinstatement
premiums expensed in the prior year related to first quarter 2011 catastrophe
activity. Our Global Reinsurance segment reported an increase in net premiums
written for the three months ended June 30, 2012 primarily due to improving
pricing conditions in our U.S. property catastrophe business. For the six months
ended June 30, 2012, this improvement was more than offset by competitive market
conditions experienced in the first quarter as well as from a non-recurring loss
portfolio transfer treaty written in the prior year. Our Life segment reported a
slight decrease in net premiums written for the three months ended June 30, 2012
primarily driven by the run-off of our Life reinsurance variable annuity
business and from lower A&H production. This decrease was offset by growth in
our Life insurance business primarily in our Asian markets. For the six months
ended June 30, 2012, our Life insurance business also benefited from prior year
acquisitions.

Net premiums earned reflect the portion of net premiums written that were
recorded as revenues for the period as the exposure periods expire. Net premiums
earned increased one percent in both the three and six months ended June 30,
2012. Our Insurance-North American segment reported an increase in net premiums
earned for the three months ended June 30, 2012 from growth in commercial and
personal lines in our retail division and growth in commercial and agriculture
lines in our wholesale and specialty division. This growth was partially offset
by our continued planned reduction of our U.S. general market risk transfer
workers' compensation business and by lower premiums associated with a couple of
large structured prospective risk management programs. Results for the six
months ended June 30, 2012 were relatively flat. In our Insurance - Overseas
General segment, results for the three months ended June 30, 2012 grew on a
constant-dollar basis driven by continued strong written premium production in
Latin American and Asia, though results reported in U.S. dollars were relatively
flat. Results for the six months ended June 30, 2012 increased on both a
constant-dollar and reported U.S. dollar basis from growth in retail P&C and A&H
lines and from the favorable impact of reinstatement premiums expensed in the
prior year. Our Global Reinsurance segment reported a decline in net premiums
earned due to consecutive lower net premiums written in prior quarters and to
the effect of a non-recurring loss portfolio transfer treaty written in the
prior year. Our Life segment reported decreased net premiums earned for the
three months ended June 30, 2012 due to the run off of our Life reinsurance
variable annuity business and from lower A&H premiums due to the effects of the
economy resulting in lower new business. Net premiums earned increased for the
six months ended June 30, 2012 primarily from business generated from prior year
acquisitions.

In evaluating our segments excluding Life, we use the combined ratio, the loss
and loss expense ratio, the policy acquisition cost ratio, and the
administrative expense ratio. We calculate these ratios by dividing the
respective expense amounts by net premiums earned. We do not calculate these
ratios for the Life segment as we do not use these measures to monitor or manage
that segment. The combined ratio is determined by adding the loss and loss
expense ratio, the policy acquisition cost ratio, and the administrative expense
ratio. A combined ratio under 100 percent indicates underwriting income and a
combined ratio exceeding 100 percent indicates underwriting loss.

The following table shows our consolidated loss and loss expense ratio, policy
acquisition cost ratio, administrative expense ratio, and combined ratio for the
periods indicated:

Total net pre-tax catastrophe losses, excluding related reinstatement premiums,
were $55 million and $74 million for the three and six months ended June 30,
2012, compared with $142 million and $557 million for the prior year periods,
respectively. Catastrophe losses through June 30, 2012 were primarily related to
severe weather related events in the U.S. Catastrophe losses through June 30,
2011 included earthquakes in Japan and New Zealand, storms in Australia, and
severe weather-related events in the U.S.

Prior period development arises from changes to loss estimates recognized in the
current year that relate to loss reserves first reported in previous calendar
years and excludes the effect of losses from the development of earned premium
from previous accident years. We experienced net favorable prior period
development of $113 million and $206 million for the three and six months ended
June 30, 2012, respectively. This compares with net favorable prior period
development of $146 million and $239 million in the prior year periods,
respectively. Refer to "Prior Period Development" for additional information.

Net investment income for the three and six months ended June 30, 2012 was $537
million and $1.1 billion, compared with $569 million and $1.1 billion for the
prior year periods, respectively. Refer to "Net Investment Income" and
"Investments" for additional information.

Policy acquisition costs consist of commissions, premium taxes, and certain
underwriting costs related directly to the successful acquisition of a new or
renewal insurance contract. Administrative expenses include all other operating
costs. Our policy acquisition cost ratio was flat for the three months ended
June 30, 2012. Our policy acquisition cost ratio increased for the six months
ended June 30, 2012 primarily from growth in personal lines and A&H business
that carry a higher acquisition cost ratio as well as increased spending to
support future growth opportunities in our Insurance - North America segment.
This increase was partially offset by lower costs in our Global Reinsurance
segment. Our administrative expense ratio decreased in the three and six months
ended June 30, 2012 primarily driven by lower regulatory costs in the Insurance
- Overseas General segment.

Our effective income tax rate, which we calculate as income tax expense divided
by income before income tax, is dependent upon the mix of earnings from
different jurisdictions with various tax rates. A change in the geographic mix
of earnings would change the effective income tax rate. Our effective income tax
rate was 31 percent and 17 percent for the three and six months ended June 30,
2012, respectively, compared with 17 percent and 20 percent for the prior year
periods, respectively. The increase in our effective income tax rate for the
three months ended June 30, 2012 was primarily due to net realized losses on
derivatives generated in lower tax-paying jurisdictions during the current year
period. The decrease in our effective income tax rate for the six months ended
June 30, 2012 was primarily due to a smaller percentage of net realized losses
on derivatives generated in lower tax-paying jurisdictions and a higher
percentage of earnings being generated in lower tax-paying jurisdictions during
the current year.

Prior Period Development


The favorable prior period development of $113 million and $206 million during
the three and six months ended June 30, 2012, respectively, was the net result
of several underlying favorable and adverse movements. In the sections following
the tables below, significant prior period movements within each reporting
segment are discussed in more detail. Long-tail lines include lines such as
workers' compensation, general liability, and professional liability; while
short-tail lines include lines such as most property lines, energy, personal
accident, aviation, and marine (including associated liability-related
exposures).

Insurance - North American

Insurance - North American's operations experienced net favorable prior period
development of $59 million in the three months ended June 30, 2012, which was
the net result of several underlying favorable and adverse movements driven by
the following principal changes:



• Net favorable development of $24 million on long-tail business, including:




                                       55

--------------------------------------------------------------------------------

Table of Contents

• Net favorable development of $38 million on our national accounts

portfolios which consist of commercial auto liability, general liability,

and workers' compensation lines of business. This favorable development

         was the net impact of favorable and adverse movements, including:




        •    Favorable development of $41 million on the 2011 accident year related
             to our annual assessment of multi-claimant events including 

industrial

             accidents. Consistent with prior years, we reviewed these 

potential

             exposures after the close of the accident year to allow for late
             reporting or identification of significant losses.




        •    Favorable development of $34 million in the 2007 accident year,
             primarily in workers' compensation. Loss activity through March 31,
             2012 was lower than expected and was included in the review completed
             during the three months ended June 30, 2012, in which we have
             increased the weighting on experienced-based methods. The favorable
             development was the combined effect of this lower than expected
             incurred loss activity and our change in method weights.



        •    Adverse development of $37 million affecting the 2006 and
prior
             accident years largely in workers' compensation. The causes for this
             adverse movement were numerous and included large increases in a small
             number of claims, higher than expected loss activity in a few accident
             years, changes in our weighting of experience-based methods, and a
             refinement of our treatment of ceded reinsurance recoveries on a few
             select treaties due to information which became known since our prior
             review.



• Adverse development of $14 million in other long-tail business across

             a number of lines and accident years, none of which was significant
             individually or in the aggregate.




  •   Favorable development of $35 million on short-tail business, including:




        •    Favorable development of $23 million in our general aviation product
             lines (both hull and liability) affecting the 2009 and prior accident
             years. Actual paid and incurred loss activity continues to be lower
             than expected based on long term historical averages leading to a
             reduction in our estimate of ultimate losses; and



• Favorable development of $12 million in other short-tail business

             across a number of lines and accident years, none of which was
             significant individually or in the aggregate.


Insurance - North American experienced net favorable prior period development of
$71 million in the three months ended June 30, 2011, which was the net result of
several underlying favorable and adverse movements, driven by the following
principal changes:



  •   Net favorable development of $46 million on long-tail business, including:




        •    Favorable development of $56 million on our national accounts
             portfolios which consist of commercial auto liability, general
             liability, and workers' compensation lines of business. The 

favorable

             development was the net impact of favorable and adverse movements,
             including:




            •   Favorable development of $40 million on the 2010 accident year
                relating to our annual assessment of multi-claimant events
                including industrial accidents. Consistent with prior years, we
                reviewed these potential exposures after the close of the accident
                year to allow for late reporting or identification of significant
                losses.




            •   Favorable development of $41 million on the 2003 through 2006
                accident years, primarily in workers' compensation. Case activity
                in these portfolios, especially in our excess and high deductible
                products, has continued to be lower than expected. As these
                accident years matured, greater weight has been given to
                experience-based methods. The combination of this lower than
                expected activity and shift in weighting methodology have produced
                this favorable development.

Table of Contents

            •   Adverse development of $25 million on the 2002 and prior accident
                years, primarily in workers' compensation. This adverse activity is
                due in part to data refinements and analysis relating to these
                accident periods.



• Adverse development of $10 million in other long-tail business across

             a number of lines and accident years, none of which was significant
             individually or in the aggregate.




  •   Favorable development of $25 million on short-tail business, including:




        •    Favorable development of $16 million in our general aviation product
             lines (both hull and liability) primarily for the 2008

accident year.

             Actual paid and incurred loss activity continues to be lower than
             expected based on long term historical averages leading to a reduction
             in our estimate of ultimate losses.



• Favorable development of $9 million in other short-tail business

             across a number of lines and accident years, none of which was
             significant individually or in the aggregate.


Insurance - Overseas General


Insurance - Overseas General experienced net favorable prior period development
of $39 million in the three months ended June 30, 2012, which was the net result
of several underlying favorable and adverse movements, driven by the following
principal changes:


• There was no prior period development on long-tail business in the three

         months ended June 30, 2012.




  •   Net favorable development of $39 million on short-tail business, including:




        •    Favorable development of $20 million on wholesale marine business.
             Favorable loss emergence across much of the short-tail first party
             marine business in accident years 2010 and 2011 led to lower
             experienced-based indications. In addition, case reductions on
             specific claims in older accident years drove reserve releases.



• Net favorable development of $15 million on short-tail property and

             technical lines in Continental Europe, excluding catastrophes.
             Favorable loss emergence in the boiler and machinery (B&M) business,
             driven by better than expected loss activity on large accounts,
             primarily in accident years 2010 and 2011 drove most of the reserve
             release. Adverse movement in fire business in accident year 2011
             driven by unfavorable loss emergence across the region

mitigated the

             impact of the favorable B&M reserve release.




        •    Favorable development of $4 million in other short-tail business
             across a number of lines and accident years, none of which was
             significant individually or in the aggregate.


Insurance - Overseas General experienced net favorable prior period development
of $40 million in the three months ended June 30, 2011, which was the net result
of several underlying favorable and adverse movements, driven by the following
principal changes:


• There was no prior period development on long-tail business in the three

         months ended June 30, 2011.




  •   Net favorable development of $40 million on short-tail business, including:




        •    Favorable development of $61 million in accident years 2009 and prior
             for property, technical, and marine lines. Given the 

short-tail nature

             of these lines and the additional credibility and maturity 

provided by

             the experience in the three months ended June 30, 2011, the 

observed

             favorable development led to lower experience-based 

indications that

             were recognized in the quarter.




        •    Adverse development of $31 million in accident year 2010 for property
             and technical lines. This indication was driven predominantly 

by

             individual large case reserve increases and higher claim 

estimates for

             the December 2010 Australian floods.

Global Reinsurance


Global Reinsurance experienced net favorable prior period development of $15
million in the three months ended June 30, 2012, which was the net result of
several underlying favorable and adverse movements, driven by the following
principal changes:



  •   Net favorable development of $15 million on long-tail business, including:




        •    Favorable development of $36 million in the casualty line of business
             principally in treaty years 2007 and prior. Following the reserve
             studies completed in the three months ended June 30, 2012, we
             reflected a greater weighting towards experience-based

methods. Since

             experience has tended to be generally favorable compared with
             assumptions, the changes resulted in the favorable development
             referenced above.




        •    Net adverse development of $18 million in the professional
             liability/D&O line of business. There was $26 million of adverse
             development related to treaty years 2006 to 2010 where the loss
             experience has been unfavorable recently due to higher than expected
             reported claims and greater reliance on experience-based methods.
             There was also favorable development of $8 million in treaty years
             2004 and prior, where experience has tended to be generally more
             favorable.



• Adverse development of $3 million in other long-tail business across a

             number of treaty years, none of which was significant

individually or

             in the aggregate.




     •   There was no prior period development on short-tail business in the three

months ended June 30, 2012.



Global Reinsurance experienced net favorable prior period development of $35
million in the three months ended June 30, 2011, which was the net result of
several underlying favorable and adverse movements, driven by the following
principal changes:



  •   Net favorable development of $35 million on long-tail business, including:




        •    Favorable development of $27 million in the casualty line of business
             principally in treaty years 2002 to 2007. Following the reserve
             studies completed in the three months ended June 30, 2011, we
             reflected a greater weighting towards experience-based

methods. Since

             experience has tended to be generally favorable compared with
             assumptions, the changes resulted in the favorable development
             referenced above.



• Favorable development of $13 million in the D&O line of business. $6

             million relates to treaty years 2002 to 2004 where the loss 

experience

             has been generally more favorable than previously anticipated, while
             the remainder relates to treaty years 2006 to 2008, where the
             potential subprime exposure has not materialized into reported losses
             to the degree anticipated.



• Adverse development of $5 million in other long-tail business across a

             number of treaty years, none of which was significant

individually or

             in the aggregate.




     •   There was no prior period development on short-tail business in the three

months ended June 30, 2011.

Insurance - North American reported an increase in net premiums written of seven
percent and four percent for the three and six months ended June 30, 2012,
respectively. Our retail business grew as a result of several factors including
rate increases, strong renewal retention, increased new business opportunities
and higher exposure base. These factors contributed to growth in most of our
businesses, primarily in property, inland marine, professional, risk management,
specialty casualty, and A&H lines of business. In addition, we continued to
generate higher personal lines production from homeowner and automobile business
offered through ACE Private Risk Services. Growth in our retail division was
partially offset by lower premiums in certain casualty and program business from
adherence to our underwriting standards; in particular, we continued our planned
reduction in our U.S. general market workers' compensation business. Our
wholesale and specialty division reported growth in property, casualty and
inland marine lines. This growth was partially offset by reduced agriculture
premiums from lower crop hail production. The overall decrease in agriculture
premiums was partially offset by increased premiums from the November 2011
acquisition of Penn Millers Insurance Company (Penn Millers).

Insurance - North American reported a three percent increase in net premiums
earned for the three months ended June 30, 2012. Net premiums earned for the six
months ended June 30, 2012 was relatively flat. Net premiums earned increased
for the three months ended June 30, 2012 due to growth in our retail division
from higher premiums earned in our property, risk management, specialty casualty
and A&H lines of business, along with growth in our personal lines business from
continued expansion of the ACE Private Risk Services product offerings. These
increases were partially offset by lower premiums associated with a couple of
large structured prospective risk management programs and the continued planned
reduction in our U.S. general market workers' compensation business. Our
wholesale and specialty division also generated higher premiums earned primarily
in our agriculture business from the acquisition of Penn Millers in November
2011, as well as from higher premiums in wholesale property and inland marine
lines. For the six months ended June 30, 2012, the growth in premiums from these
retail and wholesale and specialty businesses was more than offset by the
decline in premiums from our U.S. general market workers' compensation business
and a couple of large structured prospective risk management programs.

Insurance - North American's net catastrophe losses, excluding reinstatement
premiums, were $49 million and $65 million for the three and six months ended
June 30, 2012, compared with $110 million and $186 million for the prior year
periods, respectively. Catastrophe losses through June 30, 2012 were primarily
related to severe weather-related events in the U.S. Catastrophe losses through
June 30, 2011 were primarily related to severe weather-related events in the
U.S., including flooding in the Midwest, and the earthquake in Japan. Insurance
- North American experienced net favorable prior period development of $59
million and $119 million for the three and six months ended June 30, 2012,
compared with net favorable prior period development of $71 million and $106
million in the prior year periods, respectively. Refer to "Prior Period
Development" for additional information. The adjusted loss and loss expense
ratio decreased for the three and six months ended June 30, 2012 primarily due
to a reduction in the current accident year loss ratio for several of our
property, casualty and professional lines where execution of detailed portfolio
management plans has resulted in improved loss ratio performance.

Insurance - North American's policy acquisition cost ratio increased for the
three and six months ended June 30, 2012 due to growth in certain businesses,
including personal lines and A&H that carry a higher acquisition rate than our
other businesses, and increased spending for strategic initiatives to support
future growth opportunities.

Insurance - North American's administrative expense ratio increased slightly for
the three and six months ended June 30, 2012 primarily due to increased spending
required to support business growth primarily in our retail businesses,
including ACE Private Risk Services, and growth in spending due to the Penn
Millers acquisition.

Insurance - Overseas General's net premiums written increased two percent and
five percent for the three and six months ended June 30, 2012, respectively.
Retail P&C net premiums written increased due to new business opportunities and
rate increases in Latin America, Asia, and Europe. In addition, A&H business
continues to experience strong growth primarily in Asia and Latin America. For
the six months ended June 30, 2012, net premiums written also benefited from
favorable impact of reinstatement premiums expensed related to the first quarter
2011 catastrophe activity. Growth in the three and six months ended June 30,
2012 was partially offset by continued decreases in certain retail A&H business
due to suspension of Combined sales in the U.K. and Ireland.

Insurance - Overseas General's net premiums earned grew six percent in original
currencies for the three months ended June 30, 2012, though growth in reported
U.S. dollars was relatively flat. The constant-dollar growth was driven by
continued strong written premium performance in Latin America and Asia Pacific.
Net premiums earned grew eight percent in original currencies and four percent
in reported U.S. dollars for the six months ended June 30, 2012, driven by
growth noted in Latin America and Asia Pacific as well as reinstatement premiums
expensed in the prior year period.

The following tables provide a line of business breakdown of Insurance - Overseas General's net premiums earned for the periods indicated:

through June 30, 2012 were primarily as a result of flooding in the U.K.

Japan and Australian storm events. Insurance - Overseas General experienced net
favorable prior period development of $39 million and $61 million for the three
and six months ended June 30, 2012 compared with $40 million and $84 million in
the prior year periods, respectively. Refer to "Prior Period Development" for
additional information. The adjusted loss and loss expense ratio decreased for
the three and six months ended June 30, 2012 due to the reduction in the current
accident year loss ratio across several lines of business in several regions.

for the three months ended June 30, 2012. Insurance - Overseas General's policy
acquisition cost ratio remained relatively flat for the six months ended
June 30, 2012.

Insurance - Overseas General's administrative expense ratio decreased for the three and six months ended June 30, 2012 due to lower regulatory costs for Combined in the U.K. and Ireland.

Global Reinsurance reported a nine percent increase and a four percent decrease
in net premiums written for the three and six months ended June 30, 2012,
respectively. The increase in the three months ended June 30, 2012 was primarily
due to improving pricing conditions in our property catastrophe business. This
improvement is more than offset in our six months ended June 30, 2012 results
due to lower production in the three months ended March 31, 2012 from
competitive market conditions, adherence to underwriting standards and a
non-recurring loss portfolio transfer treaty written in the prior year.

Global Reinsurance reported a decrease in net premiums earned of seven percent
and nine percent for the three and six months ended June 30, 2012, respectively,
primarily due to consecutive annual net decreases in production resulting from
competitive market conditions, particularly in casualty and other long-tail
lines.

The following table shows the impact of catastrophe losses and related reinstatement premiums and prior period development on our loss and loss expense ratio for the periods indicated:

Global Reinsurance recorded net catastrophe losses, excluding reinstatement
premiums, of $1 million and $2 million for the three and six months ended
June 30, 2012, compared with net catastrophe losses of $22 million and $174
million in the prior year periods, respectively. The catastrophe losses in the
prior year were primarily related to earthquakes in Japan and New Zealand,
natural catastrophes in Australia and severe weather related events in the U.S.
Global Reinsurance experienced net favorable prior period development of $15
million and $26 million for the three and six months ended June 30, 2012,
respectively. This compares with net favorable prior period development of $35
million and $49 million in the prior year periods, respectively. Refer to "Prior
Period Development" for additional information. The adjusted loss and loss
expense ratio decreased through June 30, 2012 primarily due to an increase in
lower loss ratio property catastrophe business and the period over period impact
of a loss portfolio transfer treaty written in the prior year.

Global Reinsurance's policy acquisition cost ratio decreased for the three
months ended June 30, 2012 and remained relatively flat for the six months ended
June 30, 2012. Results for the three months ended June 30, 2012 reflected net
favorable adjustments on loss sensitive contract provisions.

Global Reinsurance's administrative expense ratio increased for the three and six months ended June 30, 2012 as a result of the decline in net premiums earned.

Life insurance net premiums written increased for the three months ended
June 30, 2012 due to overall growth in the business, primarily driven by our
Asian markets. Net premiums written increased in the six months ended June 30,
2012 primarily due to prior year acquisitions. Life reinsurance net premiums
written decreased for the three and six months ended June 30, 2012 because no
new life reinsurance business is currently being written. A&H net premiums
written decreased for the three and six months ended June 30, 2012 due to the
continuing effects on the economy resulting in lower new business and renewals.

Net realized gains (losses), which are excluded from life underwriting income,
relate primarily to the change in the net fair value of reported GLB reinsurance
liabilities and changes in the fair value of derivatives used to

partially offset the risk in the variable annuity guarantee portfolio. During
the three months ended June 30, 2012, realized losses were associated with an
increased value of GLB liabilities primarily due to falling equity levels and
interest rates partially offset by an increase in the value of the derivative
instruments, which increase in value when the S&P 500 index decreases. During
the six months ended June 30, 2012, realized losses were associated with an
increased value of GLB liabilities primarily due to falling interest rates and
the unfavorable impact of discounting future claims for two fewer quarters
partially offset by a decreased value of GLB liabilities due to rising equity
levels. In addition, for the six months ended June 30, 2012, we experienced a
decrease in the value of the derivative instruments, which decrease in value
when the S&P 500 index increases.

Other (income) expense includes (gains) losses from fair value changes in
separate account assets that do not qualify for separate account reporting under
GAAP. The offsetting movement in the separate account liabilities is included in
Policy benefits in the consolidated statements of operations. Equity in net
(income) loss of partially-owned entities includes our share of net (income)
loss related to investment funds, limited partnerships, partially-owned
investment companies, and partially-owned insurance companies. Certain federal
excise and capital taxes incurred as a result of capital management initiatives
are included in Other (income) expense in the consolidated statements of
operations. As these are considered capital transactions, they are excluded from
underwriting results.

Net investment income is influenced by a number of factors including the amounts
and timing of inward and outward cash flows, the level of interest rates, and
changes in overall asset allocation. Net investment income decreased six percent
and three percent for the three and six months ended June 30, 2012,
respectively. The decline in net investment income was primarily due to lower
yields on new investments and the negative impact of foreign exchange, partially
offset by positive operating cash flows and a higher overall average invested
asset base.

The investment portfolio's average market yield on fixed maturities was 2.8
percent and 3.4 percent at June 30, 2012 and 2011, respectively. Average market
yield on fixed maturities represents the weighted average yield to maturity of
our fixed income portfolio based on the market prices of the holdings at that
date.

The yield on short-term investments reflects the global nature of our insurance
operations (1.5 percent-2.0 percent yield). For example, yields on short-term
investments in Malaysia, Korea, and Ecuador range from 2.7 percent-3.9 percent.

The yield on our equity securities portfolio is high relative to the yield on
the S&P 500 Index because we classify our strategic emerging debt portfolio,
which is a mutual fund, as equity (3.7 percent - 4.5 percent yield). The
strategic emerging debt portfolio represents approximately 60 percent of our
equity securities portfolio.

Net Realized and Unrealized Gains (Losses)


We take a long-term view with our investment strategy, and our investment
managers manage our investment portfolio to maximize total return within certain
specific guidelines designed to minimize risk. The majority of our investment
portfolio is available for sale and reported at fair value. Our held to maturity
investment portfolio is reported at amortized cost.

The effect of market movements on our available for sale investment portfolio
impacts net income (through net realized gains (losses)) when securities are
sold or when we record an Other-than-temporary impairment (OTTI) charge in net
income. For a discussion related to how we assess OTTI for all of our
investments, including credit-related OTTI, and the related impact on net
income, refer to Note 3 c) to the consolidated financial statements.
Additionally, net income is impacted through the reporting of changes in the
fair value of derivatives, including financial futures, options, swaps, and GLB
reinsurance. Changes in unrealized appreciation and depreciation on available
for sale securities, which result from the revaluation of securities held, are
reported as a separate component of Accumulated other comprehensive income in
shareholders' equity in the consolidated balance sheets.

Our net realized gains (losses) for the three and six months ended June 30,
2012, included write-downs of $10 million and $20 million, respectively, as a
result of an other-than-temporary decline in fair value of certain securities.
This compares with write-downs of $8 million and $12 million for the three and
six months ended June 30, 2011, respectively.

At June 30, 2012, our investment portfolios held by U.S. legal entities included
approximately $75 million of gross unrealized losses on fixed income
investments. Our tax planning strategy related to these losses is based on our
view that we will hold these fixed income investments until they recover their
cost. As such, we have recognized a deferred tax asset of approximately $26
million related to these fixed income investments. This strategy allows us to
recognize the associated deferred tax asset related to these fixed income
investments as we do not believe these losses will ever be realized.

We engage in a securities lending program which involves lending investments to
other institutions for short periods of time. ACE invests the collateral
received in securities of high credit quality and liquidity, with the objective
of maintaining a stable principal balance. Certain investments purchased with
the securities lending collateral declined in value resulting in an unrealized
loss of $6 million at June 30, 2012. The unrealized loss is attributable to
fluctuations in market values of the underlying performing debt instruments held
by the respective mutual funds, rather than default of a debt issuer. It is our
view that the decline in value is temporary.

Investments


Our investment portfolio is invested primarily in publicly traded, investment
grade fixed income securities with an average credit quality of A/Aa as rated by
the independent investment rating services Standard and Poor's (S&P)/ Moody's
Investors Service (Moody's). The portfolio is externally managed by independent,
professional investment managers and is broadly diversified across geographies,
sectors, and issuers. Other investments principally comprise direct investments,
investment funds, and limited partnerships. We hold no collateralized debt
obligations or collateralized loan obligations in our investment portfolio and
we provide no credit default protection. We have long-standing global credit
limits for our entire portfolio across the organization. Exposures

are aggregated, monitored, and actively managed by our Global Credit Committee,
comprising senior executives, including our Chief Financial Officer, our Chief
Risk Officer, our Chief Investment Officer, and our Treasurer. We also have
well-established, strict contractual investment rules requiring managers to
maintain highly diversified exposures to individual issuers and closely monitor
investment manager compliance with portfolio guidelines.

The average duration of our fixed income securities, including the effect of
options and swaps, was 3.8 years at June 30, 2012 and 3.7 years at December 31,
2011. We estimate that a 100 basis point (bps) increase in interest rates would
reduce our book value by approximately $2.1 billion at June 30, 2012.

The following table shows the fair value and cost/amortized cost of our invested
assets:

The fair value of our total investments increased $2.1 billion during the six
months ended June 30, 2012, primarily due to the investing of operating cash
flows and unrealized appreciation.

As part of our overall investment strategy, we may invest in states,
municipalities, and other political subdivisions fixed maturity securities
(Municipal). We apply the same investment selection process described previously
to our Municipal investments. The portfolio is highly diversified primarily in
state general obligation bonds and essential service revenue bonds including
education and utilities (water, power, and sewers). As of June 30, 2012, one
state, including political subdivisions and other municipal issuers within the
state, represented approximately 17 percent of our Municipal investments. A
majority of the single state exposure represents special revenue bonds. Over 68
percent of our Municipal investments carry an S&P rating of AA- or better and
none carry fair values that reflect a significantly different risk compared to
those ratings. These Municipal investments are split 42 percent and 58 percent
between general obligation and special revenue bonds, respectively.

Our exposure to the Euro results primarily from ACE European Group which is
headquartered in London and offers a broad range of coverages throughout the
European Union, Central, and Eastern Europe. ACE primarily invests in Euro
denominated investments to support its local currency insurance obligations and
required capital levels. ACE's local currency investment portfolios have strict
contractual investment guidelines requiring managers to maintain a high quality
and diversified portfolio to both sector and individual issuers. Investment
portfolios are monitored daily to ensure investment manager compliance with
portfolio guidelines.

Our non-U.S. investment grade fixed income portfolios are currency-matched with
the insurance liabilities of our non-U.S. operations. We have 78 percent of our
non-U.S. fixed income portfolio denominated in G7 currencies. The average credit
quality of our non-U.S. fixed income securities is A and 54 percent of our
holdings are rated AAA or guaranteed by governments or quasi-government
agencies. Within the context of these investment portfolios, our government and
corporate bond holdings are highly diversified across industries and
geographies. Issuer limits are based on credit rating (AA-two percent, A-one
percent, BBB-0.5 percent of the total portfolio) and are monitored on a daily
basis by us via an internal compliance system. Because of this investment
approach we do not have a direct exposure to troubled sovereign borrowers in
Europe. We manage our indirect exposure using the same credit rating based
investment approach. Accordingly, we do not believe our indirect exposure is
material.

Our mortgage-backed securities are rated predominantly AA and comprise
approximately 23 percent of our fixed income portfolio. This compares with a 32
percent mortgage-backed weighting in representative indices of the U.S. fixed
income market at June 30, 2012. The minimum rating for our initial purchases of
mortgage-backed securities is AA for agency mortgages and AAA for non-agency
mortgages.

Agency RMBS represent securities which have been issued by Federal agencies
(Government National Mortgage Association, Federal National Mortgage
Association, and Federal Home Loan Mortgage Corporation) with implied or
explicit government guarantees. These represent 95 percent of our total RMBS
portfolio. Our non-agency RMBS are backed primarily by prime collateral and are
broadly diversified in over 47,000 loans. This portfolio's original
loan-to-value ratio is approximately 67 percent with an average Fair Isaac
Corporation (FICO) score of 730. With this conservative loan-to-value ratio and
subordinated collateral of five percent, the cumulative 5-year foreclosure rate
would have to rise to 15 percent from current levels before principal is
significantly impaired. The foreclosure rate of our non-agency RMBS portfolio at
June 30, 2012 was eight percent.

Our commercial mortgage-backed securities (CMBS) are rated predominantly AAA,
broadly diversified with over 13,000 loans with 47 percent of the portfolio
issued before 2006 and 38 percent issued after 2009. The average loan-to-value
ratio is approximately 64 percent with a debt service coverage ratio in excess
of 1.9 and weighted-average subordinated collateral of 30 percent. The
cumulative foreclosure rate would have to rise to 42 percent before principal is
impaired. The foreclosure rate for our CMBS portfolio at June 30, 2012 was
approximately 2.3 percent.

Below-investment grade corporate fixed income portfolio


Below-investment grade securities have different characteristics than investment
grade corporate debt securities. Risk of loss from default by the borrower is
greater with below-investment grade securities. Below-investment grade
securities are generally unsecured and are often subordinated to other creditors
of the issuer. Also, issuers of below-investment grade securities usually have
higher levels of debt and are more sensitive to adverse economic conditions,
such as recession or increasing interest rates, than are investment grade
issuers. At June 30, 2012, our corporate fixed income investment portfolio
included below-investment grade and non-rated securities which, in total,
comprised approximately 13 percent of our fixed income portfolio. Our
below-investment grade and non-rated portfolio includes over 990 issuers, with
the greatest single exposure being $95 million.

We manage high-yield bonds as a distinct and separate asset class from
investment grade bonds. The allocation to high yield bonds is explicitly set by
internal management and is targeted to securities in the upper tier of credit
quality (BB/B). Our minimum rating for initial purchase is BB/B. Six external
investment managers are responsible for high yield security selection and
portfolio construction. Our high yield managers have a conservative approach to
credit selection and very low historical default experience. Holdings are highly
diversified across industries and subject to a 1.5 percent issuer limit as a
percentage of high yield allocation. We monitor position limits daily through an
internal compliance system. Derivative and structured securities (e.g., credit
default swaps and collateralized loan obligations) are not permitted in the
high-yield portfolio.

Critical Accounting Estimates

As of June 30, 2012, with the exception noted below, there were no material changes to our critical accounting estimates. Refer to Note 1 to the consolidated financial statements for additional information. For full discussion of our critical accounting estimates, refer to Item 7 in our 2011 Form 10-K.


Effective January 1, 2012, we retrospectively adopted new accounting guidance
for costs associated with acquiring or renewing insurance contracts. Under the
new guidance, the definition of acquisition costs was modified to specify that a
cost must be directly related to the successful acquisition of a new or renewal
insurance contract in order to be deferred. Prior year amounts and ratios have
been adjusted to reflect the impact of retrospective adjustments as a result of
applying this new accounting guidance.

Reinsurance recoverable on policy benefits           $        257        $              249



We evaluate the financial condition of our reinsurers and potential reinsurers
on a regular basis and also monitor concentrations of credit risk with
reinsurers. The provision for uncollectible reinsurance is required principally
due to the potential failure of reinsurers to indemnify us, primarily because of
disputes under reinsurance contracts and insolvencies. The provision for
uncollectible reinsurance is based on a default analysis applied to gross
reinsurance recoverables, net of approximately $2.8 billion of collateral at
June 30, 2012 and December 31, 2011. The decrease in net reinsurance recoverable
on losses and loss expenses was primarily due to collections relating to prior
period catastrophe events and run-off operations.

Unpaid losses and loss expenses


As an insurance and reinsurance company, we are required by applicable laws and
regulations and GAAP to establish loss and loss expense reserves for the
estimated unpaid portion of the ultimate liability for losses and loss expenses
under the terms of our policies and agreements with our insured and reinsured
customers. The estimate of the liabilities includes provisions for claims that
have been reported but are unpaid at the balance sheet date (case reserves) and
for obligations on claims that have been incurred but not reported (IBNR) at the
balance sheet date. IBNR may also include provisions to account for the
possibility that reported claims may settle for amounts that differ from the
established reserves. Loss reserves also include an estimate of expenses
associated with processing and settling unpaid claims (loss expenses). At
June 30, 2012, our gross unpaid loss and loss expense reserves were $36.9
billion and our net unpaid loss and loss expense reserves were $25.9 billion.
With the exception of certain structured settlements, for which the timing and
amount of future claim payments are reliably determinable, and certain reserves
for unsettled claims that are discounted in statutory filings, our loss reserves
are not discounted for the time value of money.

Fair value measurements


The accounting guidance on fair value measurements defines fair value as the
price to sell an asset or transfer a liability in an orderly transaction between
market participants and establishes a three-level valuation hierarchy in which
inputs into valuation techniques used to measure fair value are classified.

The fair value hierarchy gives the highest priority to quoted prices in active
markets (Level 1 inputs) and the lowest priority to unobservable data (Level 3
inputs). Inputs in Level 1 are unadjusted quoted prices for identical assets or
liabilities in active markets. Level 2 includes inputs other than quoted prices
included within Level 1 that are observable for assets or liabilities either
directly or indirectly. Level 2 inputs include, among other items, quoted prices
for similar assets and liabilities in active markets, quoted prices for
identical or similar assets and liabilities in markets that are not active, and
inputs other than quoted prices that are observable for the asset or liability
such as interest rates and yield curves. Level 3 inputs are unobservable and
reflect our judgments about assumptions that market participants would use in
pricing an asset or liability.

We categorize financial instruments within the valuation hierarchy at the
balance sheet date based upon the lowest level of inputs that are significant to
the fair value measurement. Accordingly, transfers between levels within the
valuation hierarchy occur when there are significant changes to the inputs, such
as increases or decreases in market activity, changes to the availability of
current prices, changes to the transparency to underlying inputs, and whether
there are significant variances in quoted prices. Transfers in and/or out of any
level are assumed to occur at the end of the period.

While we obtain values for the majority of the investment securities we hold
from one or more pricing services, it is ultimately management's responsibility
to determine whether the values obtained and recorded in the financial
statements are representative of fair value. We periodically update our
understanding of the methodologies used by our pricing services in order to
validate that the prices obtained from those services are consistent with the
GAAP definition of fair value as an exit price. Based on our understanding of
the methodologies, our pricing services only produce an estimate of fair value
if there is observable market information that would allow them to make a fair
value estimate. Based on our understanding of the market inputs used by our
pricing services, all applicable investments have been valued in accordance with
GAAP valuation principles. We have controls to review significant price changes
and stale pricing, and to ensure that prices received from pricing services have
been accurately reflected in the consolidated financial statements. We do not
typically adjust prices obtained from pricing services.

Additionally, the valuation of fixed maturity investments is more subjective
when markets are less liquid due to the lack of market based inputs (i.e., stale
pricing), which may increase the potential that the estimated fair value of an
investment is not reflective of the price at which an actual transaction would
occur. For a small number of fixed maturities, we obtain a quote from a broker
(typically a market maker). Due to the disclaimers on the quotes that indicate
that the price is indicative only, we include these fair value estimates in
Level 3.

At June 30, 2012, Level 3 assets represented four percent of assets that are
measured at fair value and two percent of total assets. Level 3 liabilities
represented 100 percent of liabilities that are measured at fair value and two
percent of our total liabilities. During the three and six months ended June 30,
2012, we transferred $47 million and $42 million, respectively, into our Level 3
assets. During the three and six months ended June 30, 2012, we transferred $5
million and $25 million, respectively, out of our Level 3 assets. Refer to Note
4 to the consolidated financial statements for a description of the valuation
techniques and inputs used to determine fair values for our financial
instruments measured or disclosed at fair value by valuation hierarchy (Levels
1, 2, and 3) as well as a roll-forward of Level 3 financial instruments measured
at fair value for the three and six months ended June 30, 2012 and 2011.

Guaranteed living benefits (GLB) derivatives


Under life reinsurance programs covering living benefit guarantees, we assumed
the risk of GLBs associated with variable annuity (VA) contracts. We ceased
writing this business in 2007. Our GLB reinsurance product meets the definition
of a derivative for accounting purposes and is therefore carried at fair value.
We believe that the most meaningful presentation of these derivatives is to
reflect cash inflows or revenue as net premiums earned, and to record estimates
of the average modeled value of future cash outflows as incurred losses.
Accordingly, we recognize benefit reserves consistent with the accounting
guidance related to accounting and reporting by insurance enterprises for
certain non-traditional long-duration contracts and for separate accounts.
Changes in the benefit reserves are reflected as Policy benefits expense, which
is included in life underwriting income. The incremental difference between fair
value and benefit reserves is reflected in Accounts payable, accrued expenses,
and other liabilities in the consolidated balance sheet and related changes in
fair value are reflected in Net realized gains (losses) in the consolidated
statement of operations. We intend to hold these derivative contracts to
maturity (i.e., the expiration of the underlying liabilities through lapse,
annuitization, death, or expiration of the reinsurance contract). At maturity,
the cumulative gains and losses will net to zero (excluding cumulative hedge
gains or losses) because, over time, the insurance liability will be increased
or decreased to equal our obligation. For a sensitivity discussion of the effect
of changes in interest rates, equity indices, and other assumptions on the fair
value of GLBs, and the resulting impact on our net income, refer to Item 3.
Refer to our 2011 Form 10-K for additional information.

The fair value of GLB reinsurance is estimated using an internal valuation
model, which includes current market information and estimates of policyholder
behavior from the perspective of a theoretical market participant that would
assume these liabilities. All of our treaties contain claim limits, which are
factored into the valuation model. The fair value depends on a number of
factors, including interest rates, current account value, market volatility,
expected annuitization rates and other policyholder behavior, and changes in
policyholder



                                       78

mortality. The model and related assumptions are continuously re-evaluated by
management and enhanced, as appropriate, based upon additional experience
obtained related to policyholder behavior and availability of more timely market
information, such as market conditions and demographics of in-force annuities.
Due to the inherent uncertainties of the assumptions used in the valuation
models to determine the fair value of these derivative products, actual
experience may differ from the estimates reflected in our Consolidated Financial
Statements, and the differences may be material.

The most significant policyholder behavior assumptions include lapse rates and
the guaranteed minimum income benefit (GMIB) annuitization rates. Assumptions
regarding lapse rates and GMIB annuitization rates differ by treaty but the
underlying methodologies to determine rates applied to each treaty are
comparable. The assumptions regarding lapse and GMIB annuitization rates
determined for each treaty are based on a dynamic calculation that uses several
underlying factors.

A lapse rate is the percentage of in-force policies surrendered in a given
calendar year. All else equal, as lapse rates increase, ultimate claim payments
will decrease. Key factors affecting the lapse rate assumption include
investment performance and policy duration. In general, the base lapse function
assumes low lapse rates (ranging from about 1 percent to 6 percent per annum)
during the surrender charge period of the variable annuity contract, followed by
a "spike" lapse rate (ranging from about 10 percent to 30 percent per annum) in
the year immediately following the surrender charge period, and then reverting
to an ultimate lapse rate (generally around 10 percent per annum), typically
over a 2-year period. This base rate is adjusted downward for policies with more
valuable (more "in the money") guarantees by multiplying the base lapse rate by
a factor ranging from 15 percent to 75 percent. Additional lapses due to partial
withdrawals and older policyholders with tax-qualified contracts (due to
required minimum distributions) are also included.

The GMIB annuitization rate is the percentage of policies for which the
policyholder will elect to annuitize using the guaranteed benefit provided under
the GMIB. All else equal, as GMIB annuitization rates increase, ultimate claim
payments will increase, subject to treaty claim limits. Key factors affecting
the GMIB annuitization rate include investment performance and the level of
interest rates after the GMIB waiting period, since these factors determine the
value of the guarantee to the policyholder. In general, we assume that GMIB
annuitization rates will be higher for policies with more valuable (more "in the
money") guarantees. In addition, we also assume that GMIB annuitization rates
are higher in the first year immediately following the waiting period (the first
year the policies are eligible to annuitize utilizing the GMIB) in comparison to
all subsequent years. We do not yet have a robust set of annuitization
experience because most of our clients' policyholders are not yet eligible to
annuitize utilizing the GMIB. However, for certain clients representing
approximately 36 percent of the total GMIB guaranteed value there are several
years of annuitization experience - for those clients the annuitization function
reflects the actual experience and has a maximum annuitization rate per annum of
8 percent (a higher maximum applies in the first year a policy is eligible to
annuitize utilizing the GMIB - it is over 13 percent). For most clients there is
not a credible amount of observable relevant behavior data and so we use a
weighted average (with a heavier weighting on the observed experience noted
previously) of three different annuitization functions with maximum
annuitization rates per annum of 8 percent, 12 percent, and 30 percent,
respectively (with significantly higher rates in the first year a policy is
eligible to annuitize utilizing the GMIB). As noted elsewhere, our GMIB
reinsurance treaties include claim limits to protect us in the event that actual
annuitization behavior is significantly higher than expected.

During the six months ended June 30, 2012, no material changes were made to actuarial or behavior assumptions.


During the three months ended June 30, 2012, realized losses of $491 million
were associated with an increased value of GLB liabilities primarily due to
falling equity levels and interest rates. During the six months ended June 30,
2012, realized losses of $35 million were associated with an increased value of
GLB liabilities primarily due to falling interest rates and the unfavorable
impact of discounting future claims for two fewer quarters. This excludes
realized gains of $70 million and realized losses of $161 million during the
three and six months ended June 30, 2012 on derivative hedge instruments held to
partially offset the risk in the VA guarantee reinsurance

ACE Tempest Life Re employs a strategy to manage the financial market and
policyholder behavior risks embedded in the reinsurance of VA guarantees. Risk
management begins with underwriting a prospective client and guarantee design,
with particular focus on protecting our position from policyholder options that,
because of anti-selective behavior, could adversely impact our obligation.

A second layer of risk management is the structure of the reinsurance contracts.
All VA guarantee reinsurance contracts include some form of annual or aggregate
claim limit(s). The different categories of claim limits are described below:



     •   Reinsurance programs covering guaranteed minimum death benefits (GMDB)

with an annual claim limit of 2 percent of account value. This category

accounts for approximately 65 percent of the total reinsured GMDB

guaranteed value. Approximately one percent of the guaranteed value in

         this category has additional reinsurance coverage for GLB.



• Reinsurance programs covering GMDB with claim limit(s) that are a function

of the underlying guaranteed value. This category accounts for

approximately 22 percent of the total reinsured GMDB guaranteed value. The

annual claim limit expressed as a percentage of guaranteed value ranges

from 0.4 percent to 2 percent. Approximately 71 percent of guaranteed

         value in this category is also subject to annual claim deductibles that
         range from 0.1 percent to 0.2 percent of guaranteed value (i.e., our
         reinsurance coverage would only pay total annual claims in excess of 0.1

percent to 0.2 percent of the total guaranteed value). Approximately 49

percent of guaranteed value in this category is also subject to an

aggregate claim limit which was approximately $380 million as of June 30,

2012. Approximately 75 percent of guaranteed value in this category has

         additional reinsurance coverage for GLB.



• Reinsurance programs covering GMDB and guaranteed minimum accumulation

benefits (GMAB). This category accounts for approximately 18 percent of

the total reinsured GLB guaranteed value and 13 percent of the total

reinsured GMDB guaranteed value. These reinsurance programs are

quota-share agreements with the quota-share decreasing as the ratio of

         account value to guaranteed value decreases. The quota-share is 100
         percent for ratios between 100 percent and 75 percent, 60 percent for
         additional losses on ratios between 75 percent and 45 percent, and 30

percent for further losses on ratios below 45 percent. Approximately 34

percent of guaranteed value in this category is also subject to a claim

deductible of 8.8 percent of guaranteed value (i.e., our reinsurance

coverage would only pay when the ratio of account value to guaranteed

         value is below 91.2 percent).




     •   Reinsurance programs covering GMIB with an annual claim limit. This

category accounts for approximately 49 percent of the total reinsured GLB

guaranteed value. The annual claim limit is 10 percent of guaranteed value

on over 98 percent of the guaranteed value in this category. Additionally,

         reinsurance programs in this category have an annual annuitization limit
         that ranges between 17.5 percent and 30 percent with approximately 42
         percent of guaranteed value subject to an annuitization limit of 20

percent or under, and the remaining 58 percent subject to an annuitization

limit of 30 percent. Approximately 39 percent of guaranteed value in this

category is also subject to minimum annuity conversion factors that limit

the exposure to low interest rates. Approximately 42 percent of guaranteed

         value in this category has additional reinsurance coverage for GMDB.




     •   Reinsurance programs covering GMIB with aggregate claim limit. This

category accounts for approximately 33 percent of the total reinsured GLB

guaranteed value. The aggregate claim limit for reinsurance programs in

this category is approximately $1.9 billion. Additionally, reinsurance

programs in this category have an annual annuitization limit of 20 percent

and approximately 56 percent of guaranteed value in this category is also

subject to minimum annuity conversion factors that limit the exposure to

low interest rates. Approximately 44 percent of guaranteed value in this

         category has additional reinsurance coverage for GMDB.

A third layer of risk management is the hedging strategy which is focused on
mitigating long-term economic losses at a portfolio level. ACE Tempest Life Re
owned financial market instruments as part of the hedging strategy with a fair
value of ($44) million and $38 million at June 30, 2012 and December 31, 2011,
respectively. The instruments are substantially collateralized by our
counterparties, on a daily basis.

We also limit the aggregate amount of variable annuity reinsurance guarantee
risk we are willing to assume. The last substantive U.S. transaction was quoted
in mid-2007 and the last transaction in Japan was quoted in late 2007. The
aggregate number of policyholders is currently decreasing through policyholder
withdrawals and deaths at a rate of 5 percent -10 percent annually.

Note that GLB claims cannot occur for any reinsured policy until it has reached
the end of its "waiting period". The vast majority of policies we reinsure reach
the end of their "waiting periods" in 2013 or later, as shown in the table
below.

policyholders are currently ineligible to trigger a claim payment. The vast
majority of these policyholders become eligible in years 2013 and beyond. At
current market levels, we expect approximately $1 million of claims and $153
million of premium on living benefits over the next 12 months.

Collateral


In order for its U.S.-domiciled clients to obtain statutory reserve credit, ACE
Tempest Life Re holds collateral on behalf of its clients in the form of
qualified assets in trust or letters of credit, in an amount sufficient for them
to obtain statutory reserve credit. The timing of the calculation and amount of
the collateral varies by client according to the particulars of the reinsurance
treaty and the statutory reserve guidelines of the client's state of domicile.

Catastrophe management

We actively monitor our catastrophe risk accumulation around the world. The following modeled loss information reflects our in-force portfolio and reinsurance program at April 1, 2012.


The table below shows our modeled annual aggregate pre-tax probable maximum loss
(PML), net of reinsurance, for 100-year and 250-year return periods for U.S.
hurricanes and California earthquakes at June 30, 2012 and 2011. The table also
shows ACE's corresponding share of pre-tax industry losses for each of the
return periods for U.S. hurricanes and California earthquakes at June 30, 2012.
For example, according to the model, for the 1-in-100 return period scenario,
there is a one percent chance that our losses incurred in any year from U.S.
hurricanes could be in excess of $1.6 billion (or six percent of our total
shareholders' equity at June 30, 2012). We estimate that at such hypothetical
loss levels, ACE's share of aggregate industry losses would be approximately 1.0
percent.

The modeling estimates of both ACE and industry loss levels are inherently
uncertain owing to key assumptions. First, while the use of third-party
catastrophe modeling packages to simulate potential hurricane and earthquake
losses is prevalent within the insurance industry, the models are reliant upon
significant meteorology, seismology, and engineering assumptions to estimate
hurricane and earthquake losses. In particular, modeled hurricane and earthquake
events are not always a representation of actual events and ensuing additional
loss potential. Second, there is no universal standard in the preparation of
insured data for use in the models and the running of the modeling software.
Third, we are reliant upon third-party estimates of industry insured exposures
and there is significant variation possible around the relationship between our
loss and that of the industry following an event. Fourth, we assume that our
reinsurance recoveries following an event are fully collectible. These loss
estimates do not represent our potential maximum exposures and it is highly
likely that our actual incurred losses would vary materially from the modeled
estimates.

The above hurricane PMLs at June 30, 2012 reflect the findings from an in-depth
review of hurricane risk during 2011, including assessment of the latest
third-party hurricane models, implementation of the revised models through a
multi-model framework for risk assessment, and custom model output adjustments
to better reflect ACE's underlying exposure profile. The June 2011 hurricane
PMLs were based on the previous view of modeled risk.

Natural catastrophe property reinsurance program


ACE's core property catastrophe reinsurance program provides protection against
natural catastrophes impacting its primary property operations (i.e., excluding
our Global Reinsurance and Life segments) and consists of two separate towers.

We regularly review our reinsurance protection and corresponding property
catastrophe exposures. This may or may not lead to the purchase of additional
reinsurance prior to a program's renewal date. In addition, prior to each
renewal date, we consider how much, if any, coverage we intend to buy and we may
make material changes to the current structure in light of various factors,
including modeled PML assessment at various return periods, reinsurance pricing,
our risk tolerance and exposures, and various other structuring considerations.

There were no significant changes to ACE's coverage under its North American
Core Program during the second quarter. However, the North American Calabash
program expired June 15, 2012 without renewal. With respect to our International
Property Catastrophe Program, we renewed the layers of reinsurance protection in
excess of $150 million on our Core Program for the period from July 1, 2012
through June 30, 2013 with no significant change in coverage from the expiring
program. Refer to our 2011 Form 10-K for additional information.

Crop insurance


ACE is one of the leading writers of crop insurance in the U.S. Our crop
insurance business primarily comprises two components - Multiple Peril Crop
Insurance (MPCI) and hail insurance. The MPCI program is a partnership with the
U.S. Department of Agriculture (USDA), which sets the terms and conditions of
the program under the annual Standard Reinsurance Agreement (SRA). Given the
crops covered in the program, we typically see a substantial written and earned
premium impact in the second and third quarters.

MPCI represents about 85 percent of our Agriculture net premiums written; however, this percentage may change as a result of, among other things, growth in our other non-MPCI agriculture lines and changes in commodity prices.


We purchase third party stop-loss reinsurance for our MPCI business to limit our
exposure. The attachment point for this stop-loss reinsurance is based upon the
ACE underwriting loss after the impact of the SRA risk sharing between ACE and
the Federal Crop Insurance Corporation. The attachment point is approximately
equal to a 104 percent combined ratio.

Given the drought conditions in the U.S. as of July 24, 2012, we expect we will
incur approximately $68 million of additional after-tax losses, in the second
half of 2012, for our MPCI business compared to what we contemplated as of April
2012 (when we publicly announced updated earnings guidance for the calendar
year). The increased losses would result in a loss ratio increase of
approximately five percentage points, i.e., 93 percent-94 percent combined ratio
for the 2012 MPCI business. If the drought conditions worsen and continue until
harvest (of covered crops), we believe our modeled worst case loss would be
approximately an additional $200 million after-tax, in excess of the $68 million
described above.

There were no changes to the SRA during the six months ended June 30, 2012. Refer to our 2011 Form 10-K for additional information.

In June 2012, the USDA'sRisk Management Agency (RMA) released the 2013 SRA for the 2013 reinsurance year (i.e., July 1, 2012 through June 30, 2013) that replaced the 2012 SRA. There were no significant changes in the terms and conditions.

Liquidity


We anticipate that positive cash flows from operations (underwriting activities
and investment income) should be sufficient to cover cash outflows under most
loss scenarios through 2012. In addition to cash from operations, we



                                       83

--------------------------------------------------------------------------------

Table of Contents


have agreements with a third party bank provider which implemented two
international multi-currency notional cash pooling programs to enhance cash
management efficiency during periods of short-term timing mismatches between
expected inflows and outflows of cash by currency. The programs allow us to
optimize investment income by avoiding portfolio disruption. Should the need
arise, we generally have access to capital markets and available credit
facilities. At June 30, 2012, our available credit lines totaled $2.4 billion
and usage to support issued letters of credit was $1.5 billion. At July 31,
2012, usage to support issued letters of credit was $1.6 billion. Our access to
funds under existing credit facilities is dependent on the ability of the banks
that are parties to the facilities to meet their funding commitments. Our
existing credit facilities have remaining terms expiring between 2012 and 2015
and require that we maintain certain financial covenants, all of which we met at
June 30, 2012. Should any of our existing credit providers experience financial
difficulty, we may be required to replace credit sources, possibly in a
difficult market. There has also been recent consolidation in the banking
industry which could lead to increased reliance on and exposure to particular
institutions. If we cannot obtain adequate capital or sources of credit on
favorable terms, on a timely basis or at all, our business, operating results,
and financial condition could be adversely affected. To date, we have not
experienced difficulty accessing any of our credit facilities. Refer to "Credit
Facilities" in our 2011 Form 10-K.

The payments of dividends or other statutorily permissible distributions from
our operating companies are subject to the laws and regulations applicable to
each jurisdiction, as well as the need to maintain capital levels adequate to
support the insurance and reinsurance operations, including financial strength
ratings issued by independent rating agencies. During the six months ended
June 30, 2012, we were able to meet all of our obligations, including the
payments of dividends on our Common Shares, with our net cash flows.

We assess which subsidiaries to draw dividends from based on a number of
factors. Considerations such as regulatory and legal restrictions as well as the
subsidiary's financial condition are paramount to the dividend decision. The
legal restrictions on the payment of dividends from retained earnings by our
Bermuda subsidiaries are currently satisfied by the share capital and additional
paid-in capital of each of the Bermuda subsidiaries. ACE Limited received no
dividends from its Bermuda subsidiaries during the six months ended June 30,
2012. ACE Limited received dividends of $500 million from its Bermuda
subsidiaries during the six months ended June 30, 2011.

The payment of any dividends from ACE Global Markets or its subsidiaries is
subject to applicable U.K. insurance laws and regulations. In addition, the
release of funds by Syndicate 2488 to subsidiaries of ACE Global Markets is
subject to regulations promulgated by the Society of Lloyd's. The U.S. insurance
subsidiaries of ACE INA may pay dividends, without prior regulatory approval,
subject to restrictions set out in state law of the subsidiary's domicile (or,
if applicable, commercial domicile). ACE INA's international subsidiaries are
also subject to insurance laws and regulations particular to the countries in
which the subsidiaries operate. These laws and regulations sometimes include
restrictions that limit the amount of dividends payable without prior approval
of regulatory insurance authorities. ACE Limited did not receive any dividends
from ACE Global Markets or ACE INA during the six months ended June 30, 2012.
ACE Limited received dividends of $180 million from ACE Global Markets during
the six months ended June 30, 2011. ACE Limited received no dividends from ACE
INA during the six months ended June 30, 2011. Debt issued by ACE INA is
serviced by statutorily permissible distributions by ACE INA's insurance
subsidiaries to ACE INA as well as other group resources.

Cash Flows


Sources of liquidity include cash from operations, routine sales of investments,
and financing arrangements. The following is a discussion of our cash flows for
the six months ended June 30, 2012 and 2011.

Our consolidated net cash flows from operating activities were $1.4 billion in
the six months ended June 30, 2012, compared with $2.1 billion. Net loss and
loss expenses paid were $4.0 billion in the six months ended June 30, 2012,
compared with $3.8 billion. Operating cash flows decreased in the six months
ended June 30, 2012, primarily due to the $515 million unfavorable year over
year impact of cash collateral movements related to a large 2011 insurance
transaction. The receipt of $312 million cash collateral increased operating
cash flows for the six months ended June 30, 2011 while the return of $203
million cash collateral reduced operating cash flows during 2012.



                                       84

--------------------------------------------------------------------------------

Table of Contents


Our consolidated net cash flows used for investing activities were $1.3 billion
in the six months ended June 30, 2012, compared with $1.9 billion. Net investing
activities for the indicated periods were related primarily to net purchases of
fixed maturities.

Our consolidated net cash flows used for financing activities were $123 million
in the six months ended June 30, 2012, compared with $115 million. Financing
cash flows included $151 million of proceeds from issuance of short-term debt,
net of repayments, compared with $100 million. Dividends paid on Common Shares
were $318 million in the six months ended June 30, 2012, compared with $223
million.

Both internal and external forces influence our financial condition, results of
operations, and cash flows. Claim settlements, premium levels, and investment
returns may be impacted by changing rates of inflation and other economic
conditions. In many cases, significant periods of time, ranging up to several
years or more, may lapse between the occurrence of an insured loss, the
reporting of the loss to us, and the settlement of the liability for that loss.

In the current low interest rate environment, we utilize reverse repurchase
agreements as a low-cost alternative for short-term funding needs and to address
short-term cash timing differences without disrupting our investment portfolio
holdings. We subsequently settle these transactions with future operating cash
flows. At June 30, 2012, there were $1.4 billion in reverse repurchase
agreements outstanding.

Capital Resources


Capital resources consist of funds deployed or available to be deployed to
support our business operations. The following table summarizes the components
of our capital resources:

During January 2012, we repurchased $7 million of Common Shares in a series of
open market transactions under the August 2011 and November 2010 Board of
Directors authorizations. At June 30, 2012, $461 million in share repurchase
authorizations remained through December 31, 2012. At June 30, 2012 there were
3,771,527 Common Shares in treasury with a weighted average cost of $54.58 per
share.

We generally maintain the ability to issue certain classes of debt and equity
securities via an unlimited Securities and Exchange Commission (SEC) shelf
registration which is renewed every three years. This allows us capital market
access for refinancing as well as for unforeseen or opportunistic capital needs.
Our current shelf registration on file with the SEC expires in December 2014.

Dividends


We have paid dividends each quarter since we became a public company in 1993.
Under Swiss law, dividends must be stated in Swiss francs though dividend
payments are made by ACE in U.S. dollars. Following ACE's redomestication to
Switzerland in July 2008 through March 2011, dividends were distributed by way
of a par value reduction. At the May 2011 annual general meeting, our
shareholders approved dividend distributions from capital contributions reserves
(Additional paid-in capital) through the transfer of dividends from Additional
paid-in capital to Retained earnings. At the May 2012 annual general meeting,
our shareholders approved an annual dividend distribution for the following year
by way of a par value reduction equal to $1.96 per share, or CHF 1.80 per share,
calculated using the USD/CHF exchange rate as published in the Wall Street
Journal on May 10, 2012.

The annual dividend is payable in four quarterly installments, with each
installment equaling $0.49 per share, provided that the Swiss franc equivalent
of that amount per share (based on the then-current USD/CHF exchange rate),
taken together with the Swiss franc equivalents of all other installments of
this annual dividend, will not exceed 150 percent of CHF 1.80 (the aggregate
distribution cap). If the Swiss franc equivalent of an upcoming dividend
installment would cause the aggregate distribution cap to be exceeded, then that
dividend installment will be reduced to equal the Swiss franc amount remaining
available under the aggregate distribution cap, and the U.S. dollar amount
distributed for that installment will be the then-applicable U.S. dollar
equivalent of the remaining Swiss franc amount.

The following table represents dividends paid per Common Share to shareholders of record on each of the following dates:

Shareholders of record as of: Dividends paid as of:

     January 10, 2012                January 31, 2012          $0.47 (CHF 0.44)
     March 30, 2012                  April 20, 2012            $0.47 (CHF 0.42)
     July 31, 2012                   August 21, 2012           $0.49 (CHF 0.48)
