                          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. The words "believe,"
"anticipate," "estimate," "project," "should," "plan," "expect," "intend,"
"hope," "feel," "foresee," "will likely result," "will continue," and variations
thereof and similar expressions, identify forward-looking statements. 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 U.S. Securities and Exchange Commission (SEC),
include but are not limited to:
•actual amount of new and renewal business, premium rates, underwriting margins,
market acceptance of our products, and risks associated with the introduction of
new products and services and entering new markets; the competitive environment
in which we operate, including trends in pricing or in policy terms and
conditions, which may differ from our projections and changes in market
conditions that could render our business strategies ineffective or obsolete;
•losses arising out of natural or man-made catastrophes; 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, the impact of bankruptcy protection sought by various asbestos producers
and other related businesses, and the timing of loss payments;
•infection rates and severity of COVID-19 and related risks, and their effects
on our business operations and claims activity, and any adverse impact to our
insureds, brokers, agents, and employees; actual claims may exceed our best
estimate of ultimate insurance losses incurred through June 30, 2021 which could
change including as a result of, among other things, the impact of legislative
or regulatory actions taken in response to COVID-19;
•changes in the distribution or placement of risks due to increased
consolidation of insurance and reinsurance brokers; material differences between
actual and expected assessments for guaranty funds and mandatory pooling
arrangements; 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;
•uncertainties relating to governmental, legislative and regulatory policies,
developments, actions, investigations, and treaties; judicial decisions and
rulings, new theories of liability, legal tactics, and settlement terms; the
effects of data privacy or cyber laws or regulation; global political conditions
and possible business disruption or economic contraction that may result from
such events;
•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; changing rates of
inflation; and other general economic and business conditions, including the
depth and duration of potential recession;
•the availability of borrowings and letters of credit under our credit
facilities; the adequacy of collateral supporting funded high deductible
programs; the amount of dividends received from subsidiaries;
•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
maturity investments before their anticipated recovery;
•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;
•the effects of public company bankruptcies and accounting restatements, as well
as disclosures by and investigations of public companies relating to possible
accounting irregularities, and other corporate governance issues;
•acquisitions made 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, or announced acquisitions not
closing; risks and uncertainties relating to our planned purchases of additional
interests in Huatai Insurance Group Co., Ltd. (Huatai Group), including our
ability to receive Chinese insurance regulatory approval and complete the
purchases;
•risks associated with being a Swiss corporation, including reduced flexibility
with respect to certain aspects of capital management and the potential for
additional regulatory burdens; share repurchase plans and share cancellations;
•loss of the services of any of our executive officers without suitable
replacements being recruited in a reasonable time frame;

Financial Highlights for the Three Months Ended June 30, 2021



•Net income was $2.3 billion compared with a net loss of $331 million in the
prior year period. Net income in the current quarter was driven by record
underwriting results, record net investment income, and higher income related to
our partially-owned companies. Both commercial P&C and consumer lines grew
globally, reflecting positive rate increases which exceeded loss cost trend,
strong retention and higher new business.

•Total pre-tax and after-tax catastrophe losses were $280 million (3.4 percentage points of the combined ratio) and $226 million, respectively, compared with $1.8 billion (23.9 percentage points of the combined ratio) and $1.5 billion, respectively, in the prior year period, which included $1,365 million of pre-tax losses, or $1,157 million after tax, related to COVID-19.



•Total pre-tax and after-tax favorable prior period development were $268
million (3.3 percentage points of the combined ratio) and $224 million,
respectively, compared with unfavorable prior period development of $75 million
(1.0 percentage point of the combined ratio) and $52 million, respectively, in
the prior year period. The current quarter included a charge of $68 million
pre-tax for molestation claims, compared to $259 million in the prior year.

•The P&C combined ratio was 85.5 percent compared with 112.3 percent in the
prior year period. P&C current accident year combined ratio excluding
catastrophe losses was 85.4 percent compared with 87.4 percent in the prior year
period. The 2.0 percentage point decrease was substantially driven by
improvement in the loss ratio.

•Consolidated net premiums written were $9.5 billion, up 14.3 percent, or 11.5
percent in constant dollars. P&C net premiums written were $8.9 billion, up 15.5
percent, or 12.7 percent in constant dollars, comprising positive growth in both
commercial P&C lines and consumer lines of 19.9 percent and 5.6 percent,
respectively. The increase is primarily due to new business and positive rate
increases across most lines and regions. There were two items that also impacted
growth including a $184 million reduction in premium due to exposure adjustments
on in-force policies resulting from the COVID-19 pandemic in the prior year,
which was more than offset by a year-over-year decrease in large structured
transactions of $241 million. Excluding these items, P&C net premiums written
increased 16.4 percent.

•Consolidated net premiums earned were $8.8 billion, up 8.4 percent, or 5.6
percent in constant dollars. P&C net premiums earned increased 9.1 percent,
comprising positive growth in both commercial P&C lines and consumer lines of
11.6 percent and 3.8 percent, respectively. Net premiums earned increased due to
the same reasons described above for net premiums written, including from the
prior year COVID-19 exposure adjustments that depressed prior year growth by
$103 million. Partially offsetting the overall growth is the year-over-year
decrease in large structured transactions of $241 million, which are fully
earned when written.

•Net investment income was $884 million compared with $827 million in the prior year period primarily due to higher income received from our private equity partnerships and increased dividends on public equities.



•Shareholders' equity increased by $986 million in the quarter, primarily
reflecting net income of $2.3 billion and net unrealized gains on investments of
$581 million after-tax. Partially offsetting the increase was total capital
returned to shareholders in the quarter of $2.3 billion, including share
repurchases of $1.9 billion, at an average purchase price of $169.19 per share,
and dividends of $352 million. In July 2021, our Board of Directors approved a
one-time incremental share repurchase program of up to $5.0 billion through June
30, 2022.


                                                                              43

(1)Commercial multiple peril represents retail package business (property and
general liability).
(2)For purposes of this schedule only, A&H results from our Combined North
America and International businesses, normally included in the Life Insurance
and Overseas General Insurance segments, respectively, as well as the A&H
results of our North America Commercial P&C segment, are included in Global A&H
lines above.

The increase in net premiums written for the three and six months ended June 30,
2021 reflects growth across most lines of business.
•The growth in commercial casualty was due to new business and positive rate
increases, primarily across North America and Europe. Additionally, the prior
year included a $58 million reduction in premium due to exposure adjustments on
in-force policies resulting from the COVID-19 pandemic. Partially offsetting
growth is the year-over-year decrease in large structured transactions of $178
million. Excluding these items, commercial casualty increased 18.5 percent and
20.7 percent, for the three and six months ended June 30, 2021, respectively.
•Workers' compensation growth was due to a reduction in the prior year's premium
of $121 million related to exposure adjustments on in-force policies resulting
from the COVID-19 pandemic, partially offset by the year-over-year decrease in
large structured transactions. Excluding these items, workers' compensation
increased slightly reflecting new business written in small commercial and large
risk accounts.
•The increase in professional liability was due to new business and positive
rate increases in North America, Asia and Europe.
•Commercial multiple peril increased due to higher new and renewal business in
North America.
•Property and other short-tail lines increased due to positive rate increases in
Asia, North America and Europe, as well as higher new business in North America
and Europe.
•Personal lines increased globally primarily reflecting new business in
homeowners lines in North America and Latin America and growth in specialty
lines in Europe. Growth for the six months ended June 30, 2021 was partially
offset by declines in automobile lines in North America and Latin America
reflecting reduced exposures from the impact of the COVID-19 pandemic.
•Global A&H lines decreased due to declines in Asia and Latin America,
principally from less travel volume, and in our North American Combined
Insurance supplemental A&H program from the adverse impact of the COVID-19
pandemic on face-to-face and worksite sales.

•Growth in our international life operations, principally from new business
written in Taiwan, Vietnam and Thailand was partially offset by declines in our
life reinsurance business that has not written new business since 2007.
For additional information on net premiums written, refer to the segment results
discussions.

Net Premiums Earned
Net premiums earned for short-duration contracts, typically P&C contracts,
generally reflect the portion of net premiums written that was recorded as
revenues for the period as the exposure periods expire. Net premiums earned for
long-duration contracts, typically traditional life contracts, generally are
recognized as earned when due from policyholders. For the three months ended
June 30, 2021, net premiums earned increased $685 million, or 8.4 percent,
comprising 11.6 percent positive growth in commercial P&C lines and 2.9 percent
positive growth in consumer lines. For the six months ended June 30, 2021, net
premiums earned increased $1,112 million or 7.0 percent, comprising 11.5 percent
positive growth in commercial P&C lines and 0.3 percent negative growth in
consumer lines. The growth in net premiums earned was adversely impacted by the
year-over-year decrease in large structured transactions, which are fully earned
when written, partially offset by the prior year COVID-19 exposure adjustments
on in-force policies.

Catastrophe Losses and Prior Period Development
We generally define catastrophe loss events consistent with the definition of
the Property Claims Service (PCS) for events in the U.S. and Canada. PCS defines
a catastrophe as an event that causes damage of $25 million or more in insured
losses and affects a significant number of insureds. For events outside of the
U.S. and Canada, we generally use a similar definition. We also define losses
from certain pandemics, such as COVID-19, as a catastrophe loss.

Prior period development includes adjustments relating to either profit
commission reserves or policyholder dividend reserves based on actual claim
experience that develops after the policy period ends. The expense adjustments
correlate to the prior period loss development on these same policies. Refer to
the Non-GAAP Reconciliation section for further information on reinstatement
premiums on catastrophe losses and adjustments to prior period development.

                                                                   Three Months Ended                      Six Months Ended

Catastrophe losses through June 30, 2021 and 2020 were primarily from the
following events:
•2021: Winter storm losses in the U.S. and other severe weather-related events
in the U.S. and internationally.
•2020: COVID-19 pandemic claims of $1,365 million, flooding, hail, tornadoes,
and wind events in the U.S., and civil unrest in the U.S.

Prior period development (PPD) arises from changes to loss estimates recognized
in the current year that relate to loss events that occurred in previous
calendar years and excludes the effect of losses from the development of earned
premium from previous accident years.

Pre-tax net favorable PPD for the three months ended June 30, 2021 was $268
million, including adverse development of $68 million for molestation claims.
Excluding the adverse development, we had favorable development of $336 million
with 28 percent in long-tail lines, principally from accident years 2017 and
prior, and 72 percent in short-tail lines, primarily in accident and health,
property, and surety lines.

Pre-tax net favorable PPD for the six months ended June 30, 2021 was
$460 million, including adverse development of $68 million for molestation
claims described above. Excluding the adverse development, we had favorable
development of $528 million with 25 percent in long-tail lines, principally from
accident years 2017 and prior, and 75 percent in short-tail lines, primarily in
accident and health, property, and surety lines.

Pre-tax net adverse PPD for the three months ended June 30, 2020 was $75 million, including adverse development of $259 million for U.S. child molestation claims, predominantly reviver statute-related. Excluding the adverse development, we had

favorable development of $184 million split approximately 79 percent long-tail
lines, principally from accident years 2016 and prior, and 21 percent short-tail
lines.

Pre-tax net favorable PPD for the six months ended June 30, 2020 was $43
million, including adverse development of $259 million for U.S. child
molestation claims as noted above. Excluding the adverse development, we had
favorable development of $302 million split approximately 59 percent long-tail
lines, principally from accident years 2016 and prior, and 41 percent short-tail
lines.

Refer to the prior period development discussion in Footnote 6 to the Consolidated Financial Statements for additional information.



P&C Combined Ratio
In evaluating our segments excluding Life Insurance financial performance, we
use the P&C combined ratio. We calculate this ratio by dividing the respective
expense amounts by net premiums earned. We do not calculate this ratio for the
Life Insurance segment as we do not use this measure to monitor or manage that
segment. A P&C combined ratio under 100 percent indicates underwriting income,
and a combined ratio exceeding 100 percent indicates underwriting loss.

                                                                          Three Months Ended                             Six Months Ended

The loss and loss expense ratio decreased 26.5 percentage points and 11.7
percentage points for the three and six months ended June 30, 2021,
respectively, primarily due to lower catastrophe losses compared to the prior
year which included significant losses related to the COVID-19 pandemic and
higher favorable prior period development. The CAY loss ratio excluding
catastrophe losses decreased 1.8 percentage points and 1.4 percentage points for
the three and six months ended June 30, 2021, respectively, reflecting in part,
underlying loss ratio improvement.

The policy acquisition cost ratio decreased 0.1 percentage points and 0.4
percentage points for the three and six months ended June 30, 2021,
respectively, primarily due to a change in the mix of business, including less
premiums earned from consumer A&H lines that have a higher acquisition cost
ratio and higher premiums earned from commercial P&C lines that have a lower
acquisition cost ratio.

The administrative expense ratio decreased 0.2 percentage points and 0.3 percentage points for the three and six months ended June 30, 2021, respectively, primarily due to the favorable impact of higher net premiums earned.



Policy benefits
Policy benefits represent losses on contracts classified as long-duration and
generally include accident and supplemental health products, term and whole life
products, endowment products, and annuities. Refer to the Life Insurance segment
operating results section for further discussion.

For the three months ended June 30, 2021 and 2020, Policy benefits were $185
million and $223 million, respectively, which included separate account
liabilities losses of $15 million and $40 million, respectively. The offsetting
movements of these liabilities are recorded in Other (income) expense on the
Consolidated statements of operations. Excluding the separate account gains and
losses, Policy benefits were $170 million and $183 million for the three months
ended June 30, 2021 and 2020, respectively, reflecting a decline in our Combined
Insurance North America supplemental accident and health business and our life
reinsurance business, partially offset by growth in our International Life
operations.

For both the six months ended June 30, 2021 and 2020, Policy benefits were
$352 million, which included separate account liabilities (gains) losses of
$19 million and $(16) million, respectively. Excluding the separate account
gains and losses, Policy benefits were $333 million and $368 million for the six
months ended June 30, 2021 and 2020, respectively, reflecting a decline in our
Combined Insurance North America supplemental accident and health business and
our life reinsurance business, partially offset by growth in our International

Catastrophe losses through June 30, 2021 and 2020 were primarily from the
following events:
•2021: Winter storm losses and other severe weather-related events in the U.S.
•2020: COVID-19 pandemic claims of $973 million, civil unrest in the U.S. of
$118 million, and natural catastrophes including Nashville, Tennessee tornado
and other severe weather-related events in the U.S.

Refer to the prior period development discussion in Note 6 to the Consolidated Financial Statements for additional information.

Premiums


Net premiums written increased $565 million, or 15.2 percent, and $977 million,
or 14.0 percent, for the three and six months ended June 30, 2021, respectively,
comprising:
•Commercial P&C lines: Positive growth of 16.3 percent and 15.6 percent,
respectively, reflecting strong premium retention, positive rate increases, and
growth in new business written across a number of retail and wholesale lines,
including financial lines, property, excess casualty, and primary casualty. In
addition, the prior year included a $160 million reduction in premium due to
exposure adjustments on in-force policies resulting from the COVID-19 pandemic.
Partially offsetting growth in premium is the year-over-year decrease in large
structured transactions of $241 million. Adjusting for both these items, growth
in the segment would have been 18.0 percent and 15.5 percent, for the three and
six months ended June 30, 2021, respectively.
•Consumer lines: Negative growth of 8.9 percent and 14.1 percent, respectively,
principally from exposure declines in A&H.

Net premiums earned increased $208 million, or 5.8 percent, and $506 million, or
7.3 percent for the three and six months ended June 30, 2021, respectively,
reflecting the growth in net premiums written described above. In addition, the
percentage growth for the three months ended June 30, 2021 was adversely
impacted by the year-over-year decrease in large structured transactions
described above, which are fully earned when written, partially offset by $95
million of exposure adjustments on in-force policies from the COVID-19 pandemic
in the prior year, as described above. Adjusting for both these items, growth
would have been 10.4 percent and 9.6 percent, respectively.

Combined Ratio
The loss and loss expense ratio decreased 33.5 percentage points and 14.8
percentage points for the three and six months ended June 30, 2021,
respectively, primarily due to lower catastrophe losses compared to the prior
year which included significant losses related to the COVID-19 pandemic. The CAY
loss ratio excluding catastrophe losses decreased 2.4 percentage points and 1.6
percentage points for the three and six months ended June 30, 2021,
respectively. About half of the margin improvement is coming from underlying
loss ratio improvement, with the balance due to the favorable impact of lower
year-over-year large structured transactions written and non-recurring
unfavorable items in the quarter.

The policy acquisition cost ratio decreased 0.2 percentage points and 0.4 percentage points for the three and six months ended June 30, 2021, respectively, reflecting a change in mix of business towards lines that have a lower acquisition cost ratio and lower commissions, partly offset by the unfavorable impact of large structured transactions noted above.



The administrative expense ratio decreased 0.5 percentage points and 0.6
percentage points for the three and six months ended June 30, 2021,
respectively, primarily due to higher net profit from our third-party claims
administration business, ESIS, and the favorable impact of higher net premiums
earned and continued expense management. The decrease was partially offset by
the unfavorable impact of lower year-over-year large structured transactions
written.

Catastrophe losses through June 30, 2021 and 2020 were primarily from the
following events:
•2021: Winter storm losses and other severe weather-related events in the U.S.
•2020: Severe weather-related events in the U.S.

Refer to the prior period development discussion in Note 6 to the Consolidated Financial Statements for additional information.

Premiums


Net premiums written increased $36 million, or 2.6 percent, for the three months
ended June 30, 2021, primarily driven by strong renewal retention, from both
rate and exposure increases, and new business in homeowners. Partially
offsetting the increase was wildfire exposure-related cancellations in parts of
California. Net premiums written increased $27 million, or 1.1 percent, for the
six months ended June 30, 2021, primarily driven by the factors described above,
partially offset by the unfavorable impact of automobile return premiums and the
unfavorable impact of reinstatement premiums related to 2021 winter storm
losses.


                                                                              49

Net premiums earned increased $32 million, or 2.7 percent, and $16 million, or 0.7 percent for the three and six months ended June 30, 2021, respectively, reflecting the growth in net premiums written described above.



Combined Ratio
The loss and loss expense ratio decreased 8.6 percentage points and increased
1.7 percentage points for the three and six months ended June 30, 2021,
respectively, reflecting catastrophe losses and higher favorable prior period
development. The CAY loss ratio excluding catastrophe losses decreased 1.1
percentage points and 1.5 percentage points for the three and six months ended
June 30, 2021, respectively, due to lower claim frequency in automobile and in
homeowners from underlying loss ratio improvement.

The policy acquisition cost ratio increased 0.6 percentage points and 0.5 percentage points for the three and six months ended June 30, 2021, respectively, primarily due to a favorable commission accrual adjustment in the prior year.

The administrative expense ratio decreased 0.1 percentage points and 0.3 percentage points for the three and six months ended June 30, 2021, respectively, primarily due to continued expense management.

Catastrophe losses through June 30, 2021 and 2020 were primarily from winter storm losses and other severe weather-related events in the U.S. in Chubb Agribusiness.



For the six months ended June 30, 2020, net favorable prior period development
was $14 million which included $17 million of favorable incurred losses due to
lower than expected MPCI losses for the 2019 crop year, partially offset by a $3
million decrease in net premiums earned related to the MPCI profit and loss
calculation formula.

Premiums


Net premiums written increased $51 million, or 11.0 percent, and $77 million, or
12.4 percent for the three and six months ended June 30, 2021, respectively, due
to policy count growth and a modest increase in commodity price for winter wheat
in our MPCI business. In addition, our Chubb Agribusiness unit contributed to
strong new business growth.

Net premiums earned increased $34 million, or 8.9 percent, and $50 million, or
10.5 percent for the three and six months ended June 30, 2021, respectively,
reflecting the growth in net premiums written described above.

Combined Ratio
The loss and loss expense ratio decreased 2.4 percentage points and 0.4
percentage points for the three and six months ended June 30, 2021,
respectively, primarily due to higher premiums earned from Chubb Agribusiness,
which has a lower loss ratio, lower catastrophe losses, the favorable
year-over-year impact of our crop derivative, and lower underlying losses in
Chubb Agribusiness. The decrease in the loss ratio for the six months ended June
30, 2021 was mostly offset by lower favorable prior period development. The CAY
loss ratio excluding catastrophe losses decreased 1.8 percentage points and 2.5
percentage points for the three and six months ended June 30, 2021,
respectively, due to the factors noted above.

The policy acquisition cost ratio decreased 1.1 percentage points and 0.9
percentage point for the three and six months ended June 30, 2021, respectively,
primarily due to a lower year-over-year amount of supplemental commissions in
our Chubb Agribusiness unit.

The administrative expense ratio decreased 0.2 percentage points and 0.4 percentage points for the three and six months ended June 30, 2021, respectively, primarily due to the favorable impact of higher net premiums earned.

Premiums


Net premiums written increased $476 million and $768 million, or $324 million
and $517 million on a constant-dollar basis, for the three and six months ended
June 30, 2021, respectively, comprising:
•Commercial P&C lines: Positive growth of 23.4 percent and 18.8 percent,
respectively, across most regions and lines from new business and positive rate
increases.
•Consumer lines: Positive growth of 4.6 percent for the three months ended June
30, 2021 across all regions and most lines, principally in specialty personal
and homeowners lines. For the six months ended June 30, 2021, net premiums
written in our consumer lines was relatively flat as growth in the second
quarter noted above, was offset by declines in A&H in all regions, resulting
from less travel volume and lower exposures, and in automobile lines in Latin
America.

Net premiums earned increased $385 million and $556 million, or $216 million and
$305 million on a constant-dollar basis, for the three and six months ended June
30, 2021, respectively, reflecting the increase in net premiums written
described above.

Combined Ratio
The loss and loss expense ratio decreased 21.7 percentage points and 12.6
percentage points for the three and six months ended June 30, 2021,
respectively, primarily due to lower catastrophe losses and higher favorable
prior period development. The CAY loss ratio excluding catastrophe losses
decreased 1.0 percentage points and 0.9 percentage points for the three and six
months ended June 30, 2021, respectively, primarily due to margin improvements
coming from underlying loss ratio improvement and lower losses in automobile
lines in Latin America. The decrease was partially offset by lower premiums
earned from A&H lines which have a lower loss ratio.

The policy acquisition cost ratio decreased 1.3 percentage points and 1.1
percentage points for the three and six months ended June 30, 2021,
respectively, primarily due to a change in the mix of business, including less
premiums earned from A&H lines that have a higher acquisition cost ratio and
higher premiums earned from commercial P&C lines, that have a lower acquisition
cost ratio.

The administrative expense ratio decreased 0.2 percentage points and 0.3 percentage points for the three and six months ended June 30, 2021, respectively, primarily due to the favorable impact of higher net premiums earned.

Premiums
Net premiums written decreased $4 million and $29 million, or $25 million and
$56 million on a constant-dollar basis for the three and six months ended June
30, 2021, respectively. For our International Life operations, net premiums
written increased 11.6 percent and 10.7 percent for the three and six months
ended June 30, 2021, respectively, principally in Asia, from new business in
Taiwan, Vietnam and Thailand. This growth was more than offset by a decline in
our North America Combined Insurance business of 5.9 percent and 7.7 percent for
the three and six months ended June 30, 2021, respectively, due to the adverse
impact of the COVID-19 pandemic on face-to-face and worksite sales. There was
also a decline in our life reinsurance business which continues to decline as no
new business is currently being written.

Deposits collected on universal life and investment contracts (life deposits)
are not reflected as revenues in our Consolidated statements of operations in
accordance with GAAP. New life deposits are an important component of
production, and although they do not significantly affect current period income
from operations, they are key to our efforts to grow our business. Life deposits
collected increased $296 million and $404 million for the three and six months
ended June 30, 2021, respectively, primarily due to successful sales in broker
and bank channels in Taiwan.

Life Insurance underwriting income and Segment income
Life Insurance underwriting income increased $6 million for the three months
ended June 30, 2021, primarily due to higher net investment income. Life
Insurance underwriting income decreased $6 million for the six months ended June
30, 2021, primarily due to a one-time employee related benefit of $7 million in
the prior year. Segment income increased $15 million and $25 million for the
three and six months ended June 30, 2021, respectively, primarily due to our
share of net income from our investment in Huatai, our partially-owned insurance
entity in China.

Corporate

Corporate results primarily include the results of our non-insurance companies,
income and expenses not attributable to reportable segments and loss and loss
expenses of asbestos and environmental (A&E) liabilities and certain other
non-A&E run-off exposures.

                   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, net of valuation allowance.

The effect of market movements on our fixed maturities portfolio impacts Net
income (through Net realized gains (losses)) when securities are sold, when we
write down an asset, or when we record a change to the valuation allowance for
expected credit losses. For a further discussion related to how we assess the
valuation allowance for expected credit losses and the related impact on Net
income, refer to Note 1 e) to the Consolidated Financial Statements in our 2020
Form 10-K. Additionally, Net income is impacted through the reporting of changes
in the fair value of equity securities, private equity funds where we own less
than three percent, and derivatives, including financial futures, options,
swaps, and GLB reinsurance. Changes in unrealized appreciation and depreciation
on available for sale securities, resulting from the revaluation of securities
held, changes in cumulative foreign currency translation adjustment, and
unrealized postretirement benefit obligations liability adjustment, are reported
as separate components of Accumulated other comprehensive income in
Shareholders' equity in the Consolidated balance sheets.

Pre-tax net gains of $827 million in our investment portfolio for the three
months ended June 30, 2021 were principally the result of a decline in interest
rates and positive equity returns. Pre-tax net losses of $952 million in our
investment portfolio for the six months ended June 30, 2021 were principally the
result of an increase in interest rates, partially offset by positive equity
returns.

The variable annuity reinsurance derivative transactions consist of changes in
the fair value of GLB liabilities and gains or losses on other derivative
instruments we maintain that decrease in fair value when the S&P 500 index
increases. The variable annuity reinsurance derivative transactions resulted in
realized losses of $72 million for the three months ended June 30, 2021,
reflecting principally a net realized loss of $64 million related to these other
derivatives. The fair value of the GLB liabilities remained relatively flat for
the three months ended June 30, 2021, as the impact of higher global equity
markets was offset by lower interest rates. For the six months ended June 30,
2021, the variable annuity reinsurance derivative transactions resulted in
realized gains of $203 million reflecting a net gain of $311 million principally
related to a decrease in the fair value of the GLB liabilities due to higher
interest rates and higher global equity markets, partially offset by a net
realized loss of $108 million related to these other derivatives.

For the three months ended June 30, 2020, the variable annuity reinsurance
derivative transactions resulted in realized gains of $110 million, reflecting a
net decrease in the fair value of the GLB liabilities of $213 million due to
higher global equity markets, partially offset by a net realized loss of $103
million related to these other derivatives. For the six months ended June 30,
2020, the variable annuity reinsurance derivative transactions resulted in
realized losses of $450 million reflecting a net increase in the fair value of
the GLB liabilities of $472 million due to lower interest rates and lower global
equity markets, partially offset by a net realized gain of $22 million related
to these other derivatives.

                          Effective Income Tax Rate


Our effective tax rate (ETR) reflects a mix of income or losses in jurisdictions
with a wide range of tax rates, permanent differences between U.S. GAAP and
local tax laws, and the impact of discrete items. A change in the geographic mix
of earnings could impact our effective tax rate.

For the three and six months ended June 30, 2021 our ETR was 12.3 percent and
12.5 percent, respectively. The ETRs were impacted by a higher percentage of
income generated in lower tax jurisdictions and discrete tax benefits compared
to 15.8 percent and 206.8 percent for the three and six months ended June 30,
2020, respectively. In addition, the ETR for the prior period was impacted by
the high level of catastrophe losses, principally COVID-19.

                            Non-GAAP Reconciliation


In presenting our results, we included and discussed certain non-GAAP measures.
These non-GAAP measures, which may be defined differently by other companies,
are important for an understanding of our overall results of operations and
financial condition. However, they should not be viewed as a substitute for
measures determined in accordance with generally accepted accounting principles
(GAAP).

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, net of tax, divided by the shares
outstanding. We believe that goodwill and other intangible assets are not
indicative of our underlying insurance results or trends and make book value
comparisons to less acquisitive peer companies less meaningful. The calculation
of tangible book value per share does not consider the embedded goodwill
attributable to our investments in partially-owned insurance companies until we
attain majority ownership and consolidate.

We provide financial measures, including net premiums written, net premiums
earned, and underwriting income on a constant-dollar basis. We believe it is
useful to evaluate the trends in our results exclusive of the effect of
fluctuations in exchange rates between the U.S. dollar and the currencies in
which our international business is transacted, as these exchange rates could
fluctuate significantly between periods and distort the analysis of trends. The
impact is determined by assuming constant foreign exchange rates between periods
by translating prior period results using the same local currency exchange rates
as the comparable current period.

P&C performance metrics comprise consolidated operating results (including
Corporate) and exclude the operating results of the Life Insurance segment. We
believe that these measures are useful and meaningful to investors as they are
used by management to assess the company's P&C operations which are the most
economically similar. We exclude the Life Insurance segment because the results
of this business do not always correlate with the results of our P&C operations.

P&C combined ratio is the sum of the loss and loss expense ratio, policy
acquisition cost ratio and the administrative expense ratio excluding the life
business and including the realized gains and losses on the crop derivatives.
These derivatives were purchased to provide economic benefit, in a manner
similar to reinsurance protection, in the event that a significant decline in
commodity pricing impacts underwriting results. We view gains and losses on
these derivatives as part of the results of our underwriting operations.

CAY P&C combined ratio excluding catastrophe losses (CATs) excludes CATs and
prior period development (PPD) from the P&C combined ratio. We exclude CATs as
they are not predictable as to timing and amount and PPD as these unexpected
loss developments on historical reserves are not indicative of our current
underwriting performance. The combined ratio numerator is adjusted to exclude
CATs, net premiums earned adjustments on PPD, prior period expense adjustments
and reinstatement premiums on PPD, and the denominator is adjusted to exclude
net premiums earned adjustments on PPD and reinstatement premiums on CATs and
PPD. In periods where there are adjustments on loss sensitive policies, these
adjustments are excluded from PPD and net premiums earned when calculating the
ratios. We believe this measure provides a better evaluation of our underwriting
performance and enhances the understanding of the trends in our P&C business
that may be obscured by these items. This measure is commonly reported among our
peer companies and allows for a better comparison.

Reinstatement premiums are additional premiums paid on certain reinsurance
agreements in order to reinstate coverage that had been exhausted by loss
occurrences. The reinstatement premium amount is typically a pro rata portion of
the original ceded premium paid based on how much of the reinsurance limit had
been exhausted.

Net premiums earned adjustments within PPD are adjustments to the initial
premium earned on retrospectively rated policies based on actual claim
experience that develops after the policy period ends. The premium adjustments
correlate to the prior period loss development on these same policies and are
fully earned in the period the adjustments are recorded.

Prior period expense adjustments typically relate to adjustable commission
reserves or policyholder dividend reserves based on actual claim experience that
develops after the policy period ends. The expense adjustments correlate to the
prior period loss development on these same policies.

          Amortization of purchased intangibles and Other amortization


Amortization expense of purchased intangibles was $73 million and $145 million
for the three and six months ended June 30, 2021, respectively, and principally
relates to the Chubb Corp acquisition.

The following table presents, as of June 30, 2021, the estimated pre-tax
amortization expense (benefit) of purchased intangibles, at current foreign
currency exchange rates, for the third and fourth quarters of 2021 and the next
five years:

Reduction of deferred tax liability associated with intangible assets related to
Other intangible assets (excluding the fair value adjustment on Unpaid losses
and loss expense)
At June 30, 2021, the deferred tax liability associated with Other intangible
assets (excluding the fair value adjustment on Unpaid losses and loss expense)
was $1,270 million.

The following table presents, as of June 30, 2021, the expected reduction of the
deferred tax liability associated with Other intangible assets (which reduces as
agency distribution relationships and renewal rights, and other intangible
assets amortize), at current foreign currency exchange rates, for the third and

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 increased 7.0 percent
and 3.5 percent for the three and six months ended June 30, 2021, respectively,
primarily due to higher income received from our private equity partnerships and
increased dividends on public equities. Investment income for the year was
tempered by lower reinvestment rates on new and reinvested assets.

For private equities where we own less than three percent, investment income is
included within Net investment income in the table above. For private equities
where we own more than three percent, investment income is included within Other
income (expense) in the Consolidated statements of operations. Excluded from Net
investment income is the mark-to-market movement for private equities, which is
recorded within either Other income (expense) or Net realized gains (losses)
based on our percentage of ownership. The total mark-to-market movement for
private equities excluded from Net investment income was as follows:

                                  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 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 4.2 years and 4.0 years at June 30, 2021 and December 31,
2020, respectively. We estimate that a 100 basis point (bps) increase in
interest rates would reduce the valuation of our fixed income portfolio by
approximately $4.5 billion at June 30, 2021.
The following table shows the fair value and cost/amortized cost, net of
valuation allowance, of our invested assets:

The fair value of our total investments increased $2.5 billion during the six
months ended June 30, 2021 due to strong operating cash flow, positive equity
market returns, and favorable foreign currency movement. This increase was
partially offset by unrealized losses on fixed maturities, payment of dividends
on our Common Shares, and share repurchases.

Municipal
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).

Non-U.S.


Our exposure to the Euro results primarily from Chubb European Group SE which is
headquartered in France and offers a broad range of coverages throughout the
European Union, Central, and Eastern Europe. Chubb primarily invests in Euro
denominated investments to support its local currency insurance obligations and
required capital levels. Chubb'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. The average credit quality
of our non-U.S. fixed income securities is A and 48 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 daily via an internal compliance system.
We manage our indirect exposure using the same credit rating based investment
approach. Accordingly, we do not believe our indirect exposure is material.

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 investment grade issuers.
At June 30, 2021, our corporate fixed income investment portfolio included
below-investment grade and non-rated securities which, in total, comprised
approximately 15 percent of our fixed income portfolio. Our below-investment
grade and non-rated portfolio includes over 1,500 issuers, with the greatest
single exposure being $161 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. Fourteen
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 generally 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, 2021, there were no material changes to our critical accounting
estimates. For a full discussion of our critical accounting estimates, refer to
Item 7 in our 2020 Form 10-K.

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. 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, our loss reserves are not discounted for
the time value of money.

The following table presents a roll-forward of our unpaid losses and loss expenses:


                                                                  Gross               Reinsurance               Net

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 case reserves. Loss reserves also include an estimate of expenses
associated with processing and settling unpaid claims (loss expenses).

Refer to Note 6 to the Consolidated Financial Statements for a discussion on the changes in the loss reserves.



Asbestos and Environmental (A&E)
There was no significant A&E reserve activity during the three and six months
ended June 30, 2021. A&E reserves are included in Corporate. Refer to our 2020
Form 10-K for further information on our A&E exposures.

Fair value measurements
Accounting guidance defines fair value as the price to sell an asset or transfer
a liability (an exit price) in an orderly transaction between market
participants and establishes a three-level valuation hierarchy based on the
reliability of the inputs. 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). Level 2 includes inputs, other than quoted
prices within Level 1, that are observable for assets or liabilities either
directly or indirectly. Refer to Note 4 to the Consolidated Financial Statements
for information on our fair value measurements.

                            Catastrophe Management


We actively monitor and manage our catastrophe risk accumulation around the
world, including setting risk limits based on probable maximum loss (PML) and
purchasing catastrophe reinsurance. The table below presents our modeled pre-tax
estimates of natural catastrophe PML, net of reinsurance, at June 30, 2021, for
Worldwide, U.S. hurricane and California earthquake events, based on our
in-force portfolio at April 1, 2021 and reflecting the April 1, 2021 reinsurance
program (see Natural Catastrophe Property Reinsurance Program section) as well
as inuring reinsurance protection coverages. According to the model, for the
1-in-100 return period scenario, there is a one percent chance that our pre-tax
annual aggregate losses incurred in any year from U.S. hurricane events could be
in excess of $2,759 million (or 4.6 percent of our total shareholders' equity at
June 30, 2021). These estimates assume that reinsurance recoverable is fully
collectible.

(1)  Worldwide losses are comprised of losses arising only from hurricanes,
typhoons, convective storms and earthquakes and do not include "non-modeled"
perils such as wildfire and flood.
(2)  U.S. Hurricane losses include losses from wind and storm-surge and exclude
rainfall.
(3)  California earthquakes include fire-following perils.

The above estimates of Chubb's loss profile are inherently uncertain for many
reasons, including the following:
•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 catastrophe losses. In particular, modeled
catastrophe events are not always a representation of actual events and ensuing
additional loss potential;
•There is no universal standard in the preparation of insured data for use in
the models, the running of the modeling software and interpretation of loss
output. 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 potential effects of climate change add to modeling complexity; and
•Changing climate conditions could impact our exposure to natural catastrophe
risks, including U.S. hurricane. Published studies by leading government,
academic and professional organizations predict an increase in the expected
annual frequency of Atlantic-basin hurricanes and sea level rise through the end
of the century over observed historical averages. These studies contemplate
expected multi-decadal impacts of climate change on sea surface temperatures,
sea levels and other factors contributing to the frequency and intensity of
hurricanes. Based on preliminary stress tests conducted against the Chubb
portfolio at January 1, 2021, the impacts of climate change are not expected to
materially impact our reported U.S. hurricane PML over the next 12 months. These
tests reflect current exposures only and exclude potential mitigating factors,
such as changes to building codes, public or private risk mitigation, regulation
and public policy.

                Natural Catastrophe Property Reinsurance Program

Chubb's core property catastrophe reinsurance program provides protection against natural catastrophes impacting its primary property operations (i.e., excluding our Global Reinsurance and Life Insurance segments).



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.

Chubb renewed its Global Property Catastrophe Reinsurance Program for our North
American and International operations effective April 1, 2021 through March 31,
2022, with an additional $100 million of limit for international loss
occurrences compared to the expiring program. The program consists of three
layers in excess of losses retained by Chubb on a per occurrence basis. In
addition, Chubb also renewed its terrorism coverage (excluding nuclear,
biological, chemical and radiation coverage, with an inclusion of coverage for
biological and chemical coverage for personal lines) for the United States from
April 1, 2021 through March 31, 2022 with the same limits and retention and
percentage placed except that the majority of terrorism coverage is on an
aggregate basis above our retentions without a reinstatement.

                                   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 for the near term. In addition to cash from operations, routine
sales of investments, and financing arrangements, we 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 to credit facilities with letter of credit capacity of
$3.7 billion with a sub-limit of $1.9 billion for revolving credit. At June 30,
2021, our usage under these facilities was $1.4 billion in letters of credit.
Our access to credit under these facilities is dependent on the ability of the
banks that are a party to the facilities to meet their funding commitments. The
facilities require that we maintain certain financial covenants, all of which we
met at June 30, 2021. Should the existing credit providers on these facilities
experience financial difficulty, we may be required to replace credit sources,
possibly in a difficult market. 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 our credit facilities.

The payment 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,
2021, we were able to meet all 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. Chubb
Limited received dividends of $1.8 billion and nil from its Bermuda subsidiaries
during the six months ended June 30, 2021 and 2020, respectively. Chubb Limited
received cash dividends of $21 million and $110 million and non-cash dividends
of $536 million and $734 million from a Swiss subsidiary during the six months
ended June 30, 2021 and 2020, respectively.

The payment of any dividends from CGM 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 CGM is subject to regulations
promulgated by the Society of Lloyd's. The U.S. insurance subsidiaries of Chubb
INA Holdings Inc. (Chubb 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). Chubb 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. Chubb Limited
received no dividends from CGM or Chubb INA during the six months ended June 30,
2021 and 2020. Debt issued by Chubb INA is serviced by statutorily permissible
distributions by Chubb INA's insurance subsidiaries to Chubb INA as well as
other group resources. Chubb INA received $470 million and nil from its
subsidiaries during the six months ended June 30, 2021 and 2020, respectively.

Cash Flows
Our 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, 2021 and 2020.

Operating cash flows were $5.2 billion in the six months ended June 30, 2021,
compared to $3.7 billion in the prior year period. The increase of $1.5 billion
is due to higher premiums collected reflecting premium growth, principally in
our commercial lines. Partially offsetting the increase are higher catastrophe
loss payments and higher taxes paid.

Cash used for investing was $2.0 billion in the six months ended June 30, 2021,
compared to $2.7 billion in the prior year period. Cash used for investing
principally relates to net purchases of fixed maturities. In addition, the prior
year included cash used for the incremental purchase of Huatai Group ownership
interest of $1.6 billion.

Cash used for financing was $3.0 billion in the six months ended June 30, 2021,
compared to $898 million in the prior year period, an increase of $2.1 billion
principally from more shares repurchased in the current year.

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.

We use repurchase agreements as a low-cost funding alternative. At June 30, 2021, there were $1.4 billion in repurchase agreements outstanding with various maturities over the next nine months.

Repurchase agreements are excluded from the table above and are disclosed
separately from short-term debt in the Consolidated balance sheets. The
repurchase agreements are collateralized borrowings where we maintain the right
and ability to redeem the collateral on short notice, unlike short-term debt
which comprises the current maturities of our long-term debt instruments.

For the six months ended June 30, 2021, we repurchased $2.44 billion of Common
Shares in a series of open market transactions under the Board of Directors
(Board) share repurchase authorization. At June 30, 2021, there were 38,888,051
Common Shares in treasury with a weighted average cost of $148.42 per share, and
$65 million in share repurchase authorization remained through December 31,
2021. Subsequently, on July 19, 2021, the Board authorized a one-time
incremental share repurchase program of up to $5.0 billion through June 30,
2022. At July 28, 2021, $5.06 billion in share repurchase authorizations
remained.

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.

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 Chubb in U.S. dollars. Refer to Note 8 to the Consolidated
Financial Statements for a discussion of our dividend methodology.

At our May 2021 annual general meeting, our shareholders approved an annual
dividend for the following year of up to $3.20 per share, or CHF 2.87 per share,
calculated using the USD/CHF exchange rate as published in the Wall Street
Journal on May 20, 2021, expected to be paid in four quarterly installments of
$0.80 per share after the general meeting by way of a distribution from capital
contribution reserves, transferred to free reserves for payment. The Board
determines the record and payment dates at which the annual dividend may be paid
until the date of the 2022 annual general meeting, and is authorized to abstain
from distributing a dividend at its discretion. The annual dividend approved in
May 2021 represented a $0.08 per share increase ($0.02 per quarter) over the
prior year dividend.

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:
