___________________________________________


(1)    On December 22, 2017, the U.S. enacted the Tax Cuts and Jobs Act of 2017
       (TCJA) which, among other changes, reduced the U.S. Federal tax rate from

35% to 21% beginning on January 1, 2018 and imposed a tax on undistributed

and previously untaxed post-1986 foreign earnings and profits (accumulated

foreign earnings). Total income tax expense for 2017 included a net charge

of $129 million to reflect the estimated impact of the changes in tax law


       and tax rates included in TCJA at the date of enactment, primarily
       reflecting the revaluation of the Company's deferred tax assets and
       liabilities at the new statutory federal tax rate of 21%, and the
       recognition of tax imposed on the accumulated foreign earnings.


The following discussions of the Company's net income and segment income are
presented on an after-tax basis.  Discussions of the components of net income
and segment income are presented on a pre-tax basis, unless otherwise noted.
Discussions of earnings per common share are presented on a diluted basis.
Overview
Diluted net income per share of $9.92 in 2019 increased by 7% over diluted net
income per share of $9.28 in 2018. Net income of $2.62 billion in 2019 increased
by 4% over net income of $2.52 billion in 2018. The higher rate of increase in
diluted net income per share reflected the impact of share repurchases in recent
periods. The increase in income before income taxes primarily reflected the
pre-tax impacts of (i) significantly lower catastrophe losses, partially offset
by (ii) net unfavorable prior year reserve development in 2019 compared to net
favorable prior year reserve development in 2018 and (iii) lower underwriting
margins excluding catastrophe losses and prior year reserve development
("underlying underwriting margins"). Catastrophe losses in 2019 and 2018 were
$886 million and $1.72 billion, respectively. Net unfavorable prior year reserve
development in 2019 was $60 million, compared to net favorable prior year
reserve development of $517 million in 2018. Underlying underwriting margins in
each of the Company's business segments were lower than in 2018. Income tax
expense in 2019 was higher than in 2018, primarily

                                       62
--------------------------------------------------------------------------------


reflecting the impacts of (i) the increase in income before income taxes and
(ii) the reduction in income tax expense in 2018 resulting from the Company's
$200 million voluntary contribution to its qualified domestic pension plan,
which provided a 35% tax benefit rather than a 21% tax benefit.

The Company has insurance operations in Canada, the United Kingdom, the Republic
of Ireland and throughout other parts of the world as a corporate member of
Lloyd's, as well as in Brazil and Colombia, primarily through joint ventures.
Because these operations are conducted in local currencies other than the U.S.
dollar, the Company is subject to changes in foreign currency exchange rates.
For the years ended December 31, 2019 and 2018, changes in foreign currency
exchange rates impacted reported line items in the statement of income by
insignificant amounts. The impact of these changes was not material to the
Company's net income or segment income for the periods reported.

Revenues


Earned Premiums
Earned premiums in 2019 were $28.27 billion, $1.21 billion or 4% higher than in
2018. In Business Insurance, earned premiums in 2019 increased by 4% over 2018.
In Bond & Specialty Insurance, earned premiums in 2019 increased by 6% over
2018. In Personal Insurance, earned premiums in 2019 increased by 5% over 2018.
Factors contributing to the increases in earned premiums in each segment in 2019
as compared with 2018 are discussed in more detail in the segment discussions
that follow.

Net Investment Income
The following table sets forth information regarding the Company's investments.
(for the year ended December 31, in millions)      2019         2018         2017

       receivables for investment sales, payables on investment purchases and
       accrued investment income.

(2) Excludes net realized and net unrealized investment gains and losses.




Net investment income in 2019 was $2.47 billion, comparable with 2018. Net
investment income from fixed maturity investments in 2019 was $2.07 billion, $90
million higher than in 2018, primarily resulting from a higher average level of
fixed maturity investments and higher long-term interest rates. Net investment
income from short-term securities in 2019 was $105 million, $13 million higher
than in 2018, primarily resulting from higher short-term interest rates. Net
investment income generated by the Company's remaining investment portfolios in
2019 was $333 million, $108 million lower than in 2018, primarily reflecting
lower returns from private equity limited partnerships and real estate
partnerships.

Fee Income
The National Accounts market in Business Insurance is the primary source of the
Company's fee-based business.  Fee income is described in more detail in the
Business Insurance discussion that follows.

Other Net Realized Investment Gains
Other net realized investment gains in 2019 included $59 million of net realized
investment gains related to fixed maturity investments, $12 million of net
realized investment gains related to equity securities sold and $15 million of
net realized investment losses related to foreign currency translation and other
investments.

Other net realized investment gains in 2018 included $92 million of net realized
investment gains related to other investments, primarily resulting from the sale
of a private equity limited partnership, $33 million of net realized gains
related to fixed maturity investments, $23 million of net realized investment
gains from real estate sales and $4 million of net realized investment losses
related to equity securities sold.

Other Revenues
Other revenues in all years presented included installment premium charges.
Other revenues in all years also included revenues from Simply Business, which
was acquired in August 2017. Other revenues in 2017 also included a gain related
to the settlement of a reinsurance dispute.

Claims and Expenses
Claims and Claim Adjustment Expenses
Claims and claim adjustment expenses in 2019 were $19.13 billion, $842 million
or 5% higher than in 2018, primarily reflecting the impacts of (i) net
unfavorable prior year reserve development compared to net favorable prior year
reserve development in 2018, (ii) loss cost trends, (iii) higher loss estimates
in the general liability line for primary and excess coverages and in the
commercial automobile product line, (iv) higher business volumes and (v) higher
non-catastrophe weather-related losses, partially offset by (vi) significantly
lower catastrophe losses and (vii) lower loss estimates in the workers'
compensation product line. Catastrophes in 2019 primarily resulted from
Hurricane Dorian and several winter, wind and hail storms throughout the United
States. Catastrophes in 2018 primarily resulted from wildfires in California,
Hurricanes Florence and Michael, wind and hail storms in several regions of the
United States and winter storms in the eastern United States.

Factors contributing to net prior year reserve development during the years
ended December 31, 2019, 2018 and 2017 are discussed in more detail in note 7 of
notes to the consolidated financial statements.
Significant Catastrophe Losses
The Company defines a "catastrophe" as an event:
•         that is designated a catastrophe by internationally recognized
          organizations that track and report on insured losses resulting from
          catastrophic events, such as Property Claim Services (PCS) for events
          in the United States and Canada; and


•         for which the Company's estimates of its ultimate losses before
          reinsurance and taxes exceed a pre-established dollar threshold.


The Company's threshold for disclosing catastrophes is primarily determined at
the reportable segment level. If a threshold for one segment or a combination
thereof is exceeded and the other segments have losses from the same event,
losses from the event are identified as catastrophe losses in the segment
results and for the consolidated results of the Company. Additionally, an

                                       64
--------------------------------------------------------------------------------


aggregate threshold is applied for International business across all reportable
segments. The threshold for 2019 ranged from approximately $19 million to $30
million of losses before reinsurance and taxes.

The following table presents the amount of losses recorded by the Company for
significant catastrophes that occurred in 2019, 2018 and 2017, the amount of net
unfavorable (favorable) prior year reserve development recognized in 2019 and
2018 for catastrophes that occurred in 2018 and 2017, and the estimate of
ultimate losses for those catastrophes at December 31, 2019, 2018 and 2017. For
purposes of the table, a significant catastrophe is an event for which the
Company estimates its ultimate losses will be $100 million or more after
reinsurance and before taxes.
                                                                      Losses Incurred / Unfavorable (Favorable)

(1) Amounts are reported pre-tax and net of recoveries under all applicable
reinsurance treaties, except for the Underlying Property Aggregate Catastrophe
Excess-of-Loss Treaty, the terms of which are described in "Part I-Item
1-Business." That treaty covers the accumulation of certain property losses
arising from one or multiple occurrences (both catastrophe and non-catastrophe
events) for the period January 1, 2019 through and including December 31, 2019.
As a result, the benefit from that treaty is not included in the table above as

Amortization of Deferred Acquisition Costs
Amortization of deferred acquisition costs in 2019 was $4.60 billion, $220
million or 5% higher than in 2018. Amortization of deferred acquisition costs is
discussed in more detail in the segment discussions that follow.

General and Administrative Expenses



General and administrative expenses in 2019 were $4.37 billion, $68 million or
2% higher than in 2018, primarily reflecting the impact of costs associated with
higher business volumes. General and administrative expenses are discussed in
more detail in the segment discussions that follow.

                                       65
--------------------------------------------------------------------------------



Interest Expense
Interest expense in 2019 and 2018 was $344 million and $352 million,
respectively.
Income Tax Expense
Income tax expense in 2019 was $516 million, $78 million or 18% higher than in
2018, primarily reflecting the impacts of (i) the $177 million increase in
income before income taxes in 2019 and (ii) the reduction in income tax in 2018
resulting from the Company's $200 million voluntary contribution to its
qualified domestic pension plan, which provided a 35% tax benefit rather than a
21% tax benefit.

The Company's effective tax rate was 16%, 15% and 25% in 2019, 2018 and 2017,
respectively. The effective tax rates in all years were lower than the
respective statutory rate of 21% in both 2019 and 2018 and 35% in 2017,
primarily due to the impact of tax-exempt investment income on the calculation
of the Company's income tax provision. The effective tax rate in 2018 also
included the impact of the reduction in income tax expense resulting from the
Company's $200 million voluntary contribution to its qualified domestic pension
plan in 2018, which provided a 35% tax benefit rather than a 21% tax benefit.
The effective tax rate in 2017 reflected the net charge related to TCJA and the
impact of the resolution of prior year tax matters.

Combined Ratio
The combined ratio of 96.5% in 2019 was 0.4 points lower than the combined ratio
of 96.9% in 2018. The loss and loss adjustment expense ratio of 66.9% in 2019
was 0.1 points higher than the loss and loss adjustment expense ratio of 66.8%
in 2018. The underwriting expense ratio of 29.6% in 2019 was 0.5 points lower
than the underwriting expense ratio of 30.1% in 2018.

Catastrophe losses in 2019 and 2018 accounted for 3.1 points and 6.3 points,
respectively, of the combined ratio. Net unfavorable prior year reserve
development in 2019 accounted for 0.2 points of the combined ratio. Net
favorable prior year reserve development in 2018 provided 1.9 points of benefit
to the combined ratio. The combined ratio excluding prior year reserve
development and catastrophe losses ("underlying combined ratio") in 2019 was 0.7
points higher than the 2018 ratio on the same basis, primarily reflecting the
impacts of (i) higher loss estimates in the general liability product line for
primary and excess coverages and in the commercial automobile product line, (ii)
the impact on earned premiums related to the Company's new catastrophe
reinsurance treaty and (iii) higher non-catastrophe weather-related losses,
partially offset by (iv) lower loss estimates in the workers' compensation
product line.

In recent periods, both prior year reserve development and the underlying combined ratio have been impacted by adverse developments in the tort environment, including more aggressive attorney involvement in insurance claims.



Written Premiums
Consolidated gross and net written premiums were as follows:

Gross and net written premiums in 2019 increased by 6% and 5%, respectively,
over 2018. Net written premium growth in 2019 was impacted by ceded written
premiums related to the new catastrophe reinsurance treaty entered into in the
first quarter of 2019.

___________________________________________


(1)    On December 22, 2017, the U.S. enacted the Tax Cuts and Jobs Act of 2017
       (TCJA) which, among other changes, reduced the U.S. Federal tax rate from

35% to 21% beginning on January 1, 2018 and imposed a tax on undistributed

and previously untaxed post-1986 foreign earnings and profits (accumulated


       foreign earnings).


Overview


Segment income in 2019 was $1.39 billion, $246 million or 15% lower than segment
income of $1.64 billion in 2018. The decrease in segment income before income
taxes primarily reflected the pre-tax impacts of (i) net unfavorable prior year
reserve development in 2019 compared to net favorable prior year reserve
development in 2018 and (ii) lower underlying underwriting margins, partially
offset by (iii) lower catastrophe losses. Net unfavorable prior year reserve
development in 2019 was $258 million. Net favorable prior year reserve
development in 2018 was $142 million. Catastrophe losses in 2019 and 2018 were
$470 million and $639 million, respectively. The lower underlying underwriting
margins primarily reflected the impacts of (i) higher loss estimates in the
general liability product line for primary and excess coverages and in the
commercial automobile product line and (ii) the impact on earned premiums
related to the Company's new catastrophe reinsurance treaty, partially offset by
(iii) higher business volumes and (iv) lower loss estimates in the workers'
compensation product line. Income tax expense in 2019 was lower than in 2018,
primarily reflecting the impacts of (i) the decrease in segment income before
income taxes, partially offset by (ii) the reduction in income tax expense in
2018 resulting from the Company's voluntary contribution to its qualified
domestic pension plan.

Revenues


Earned Premiums
Earned premiums of $15.30 billion in 2019 were $578 million or 4% higher than in
2018, primarily reflecting an increase in net written premiums over the
preceding twelve months, partially offset by the earned impact of the new
catastrophe reinsurance treaty.

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


Net Investment Income
Net investment income in 2019 was $1.82 billion, $17 million or 1% lower than in
2018. Refer to the "Net Investment Income" section of the "Consolidated Results
of Operations" discussion for a description of the factors contributing to the
Company's consolidated net investment income in 2019 compared with 2018. In
addition, refer to note 2 of notes to the consolidated financial statements for
a discussion of the Company's net investment income allocation methodology.

Fee Income
National Accounts is the primary source of fee income due to revenue from its
large deductible policies and service businesses, which include risk management,
claims administration, loss control and risk management information services
provided to third parties, as well as claims and policy management services to
workers' compensation residual market pools. Fee income in 2019 was $437
million, $25 million or 6% higher than in 2018, primarily reflecting higher
claim volume under administration associated with its service businesses.

Other Revenues
Other revenues in all years presented included installment premium charges and
other policyholder service charges, as well as revenues from Simply Business,
which was acquired in August 2017.

Claims and Expenses
Claims and Claim Adjustment Expenses
Claims and claim adjustment expenses in 2019 were $10.96 billion, $792 million
or 8% higher than in 2018, primarily reflecting the impacts of (i) net
unfavorable prior year reserve development in 2019 compared to net favorable
prior year reserve development in 2018, (ii) loss cost trends, (iii) higher loss
estimates in the general liability product line for primary and excess coverages
and the commercial automobile product line and (iv) higher business volumes,
partially offset by (v) lower catastrophe losses and (vi) lower loss estimates
in the workers' compensation product line.

Factors contributing to net prior year reserve development during the years ended December 31, 2019, 2018 and 2017 are discussed in more detail in note 7 of notes to the consolidated financial statements.



Amortization of Deferred Acquisition Costs
Amortization of deferred acquisition costs in 2019 was $2.50 billion, $115
million or 5% higher than in 2018, generally consistent with the increase in
earned premiums.

General and Administrative Expenses
General and administrative expenses in 2019 were $2.63 billion, comparable with
2018.

Income Tax Expense
Income tax expense in 2019 was $223 million, $36 million or 14% lower than in
2018, primarily reflecting the impacts of (i) the $282 million decrease in
income before income taxes in 2019, partially offset by (ii) the reduction in
income tax expense in 2018 resulting from the Company's voluntary contribution
to its qualified domestic pension plan in 2018.

Combined Ratio
The combined ratio of 100.9% in 2019 was 1.8 points higher than the combined
ratio of 99.1% in 2018. The loss and loss adjustment expense ratio of 70.3% in
2019 was 2.5 points higher than the loss and loss adjustment expense ratio of
67.8% in 2018. The underwriting expense ratio of 30.6% in 2019 was 0.7 points
lower than the underwriting expense ratio of 31.3% in 2018.

Catastrophe losses in 2019 and 2018 accounted for 3.0 points and 4.4 points,
respectively, of the combined ratio. Net unfavorable prior year reserve
development in 2019 accounted for 1.7 points of the combined ratio. Net
favorable prior year reserve development in 2018 provided 1.0 points of benefit
to the combined ratio. The underlying combined ratio in 2019 was 0.5 points
higher than the 2018 ratio on the same basis, primarily reflecting the impacts
of (i) higher loss estimates in the general liability product line for primary
and excess coverages and the commercial automobile product line and (ii) the
impact on earned premiums related to

                                       68
--------------------------------------------------------------------------------

the Company's new catastrophe reinsurance treaty, partially offset by (iii) lower loss estimates in the workers' compensation product line and (iv) a lower underwriting expense ratio.

(1)    On December 22, 2017, the U.S. enacted the Tax Cuts and Jobs Act of 2017
       (TCJA) which, among other changes, reduced the U.S. Federal tax rate from

35% to 21% beginning on January 1, 2018 and imposed a tax on undistributed

and previously untaxed post-1986 foreign earnings and profits (accumulated


       foreign earnings).


Overview


Segment income in 2019 was $618 million, $175 million or 22% lower than segment
income of $793 million in 2018. The decrease in segment income before income
taxes primarily reflected the pre-tax impacts of (i) lower net favorable prior
year reserve development and (ii) lower underlying underwriting margins. Net
favorable prior year reserve development in 2019 and 2018 was $65 million and
$266 million, respectively. Catastrophe losses in 2019 and 2018 were $5 million
and $16 million, respectively. The lower underlying underwriting margins
primarily reflected modestly higher loss estimates in the domestic general
liability product line for management liability coverages. Income tax expense in
2019 was lower than in 2018, primarily reflecting the impact of the decrease in
segment income before income taxes.

Revenues


Earned Premiums
Earned premiums in 2019 were $2.57 billion, $145 million or 6% higher than in
2018, primarily reflecting an increase in net written premiums over the
preceding twelve months.

Net Investment Income
Net investment income in 2019 was $233 million, level with 2018. Included in
Bond & Specialty Insurance are certain legal entities whose invested assets and
related net investment income are reported exclusively in this segment and not
allocated among all business segments. As a result, reported net investment
income in Bond & Specialty Insurance reflects a significantly smaller proportion
of allocated net investment income, including net investment income from the
Company's non-fixed maturity investments that experienced a decrease in
investment income in 2019. Refer to the "Net Investment Income" section of the
"Consolidated Results of Operations" discussion for a description of the factors
contributing to the Company's consolidated net investment income in 2019 as
compared with the 2018. In addition, refer to note 2 of notes to the
consolidated financial statements for a discussion of the Company's net
investment income allocation methodology.

Claims and Expenses
Claims and Claim Adjustment Expenses
Claims and claim adjustment expenses in 2019 were $1.09 billion, $322 million or
42% higher than in 2018, primarily reflecting the impacts of (i) lower net
favorable prior year reserve development, (ii) higher business volumes and (iii)
modestly higher loss estimates in the domestic general liability product line
for management liability coverages.

Factors contributing to net favorable prior year reserve development during the
years ended December 31, 2019, 2018 and 2017 are discussed in more detail in
note 7 of notes to the consolidated financial statements.

Amortization of Deferred Acquisition Costs
Amortization of deferred acquisition costs in 2019 was $478 million, $24 million
or 5% higher than in 2018, generally consistent with the increase in earned
premiums.

General and Administrative Expenses
General and administrative expenses in 2019 were $483 million, $24 million or 5%
higher than in 2018, primarily reflecting the impact of costs associated with
higher business volumes.

Income Tax Expense
Income tax expense in 2019 was $151 million, $47 million or 24% lower than in
2018, primarily reflecting the impact of the $222 million decrease in income
before income taxes in 2019.

Combined Ratio
The combined ratio of 79.5% in 2019 was 10.5 points higher than the combined
ratio of 69.0% in 2018. The loss and loss adjustment expense ratio of 42.2% in
2019 was 10.7 points higher than the loss and loss adjustment expense ratio of
31.5% in 2018. The underwriting expense ratio of 37.3% in 2019 was 0.2 points
lower than the underwriting expense ratio of 37.5% in 2018.

Net favorable prior year reserve development in 2019 and 2018 provided 2.5
points and 11.0 points of benefit, respectively, to the combined ratio.
Catastrophe losses in 2019 and 2018 accounted for 0.2 points and 0.6 points,
respectively, of the combined ratio. The underlying combined ratio in 2019 was
2.4 points higher than the 2018 ratio on the same basis, primarily reflecting
the impacts of modestly higher loss estimates in the domestic general liability
product line for management liability coverages.

Written Premiums Bond & Specialty Insurance's gross and net written premiums were as follows:

Gross written premiums in 2019 increased by 10% over 2018. Net written premiums
in 2019 increased by 8% over 2018. Net written premium growth in 2019 was
impacted by higher ceded written premiums for several reinsurance treaties,
including those related to the new catastrophe reinsurance treaty entered into
in the first quarter of 2019.

Domestic. Net written premiums in 2019 were $2.47 billion, $181 million or 8%
higher than in 2018. Excluding the surety line of business, for which the
following are not relevant measures, business retention rates remained strong in
2019. Renewal premium changes in 2019 remained positive and were higher than in
2018. New business premiums in 2019 increased over 2018.

International. Net written premiums in 2019 were $268 million, $30 million or
13% higher than in 2018, primarily driven by increases in the United Kingdom and
Canada, partially offset by the impact of changes in foreign currency exchange
rates.

___________________________________________


(1)    On December 22, 2017, the U.S. enacted the Tax Cuts and Jobs Act of 2017
       (TCJA) which, among other changes, reduced the U.S. Federal tax rate from

Overview


Segment income in 2019 was $824 million, $527 million or 177% higher than
segment income of $297 million in 2018. The increase in segment income before
income taxes primarily reflected the pre-tax impacts of (i) significantly lower
catastrophe losses and (ii) higher net favorable prior year reserve development,
partially offset by (iii) lower underlying underwriting margins. Catastrophe
losses in 2019 and 2018 were $411 million and $1.06 billion, respectively. Net
favorable prior year reserve development in 2019 and 2018 was $133 million and
$109 million, respectively. The lower underlying underwriting margins primarily
reflected

                                       72
--------------------------------------------------------------------------------


(i) higher non-catastrophe weather-related losses in Agency Homeowners and Other
and (ii) the impact on earned premiums related to the Company's new catastrophe
reinsurance treaty, mostly impacting Agency Homeowners and Other, partially
offset by (iii) earned pricing that exceeded loss cost trends in Agency
Automobile and (iv) higher business volumes. Income tax expense in 2019 was
higher than in 2018, primarily reflecting the impacts of (i) the increase in
segment income before income taxes and (ii) the reduction in income tax expense
in 2018 resulting from the Company's voluntary contribution to its qualified
domestic pension plan.

Revenues
Earned Premiums
Earned premiums in 2019 were $10.41 billion, $490 million or 5% higher than in
2018, primarily reflecting an increase in net written premiums over the
preceding twelve months. The increase in earned premiums in 2019 was reduced by
the earned impact of the new catastrophe reinsurance treaty.

Net Investment Income
Net investment income in 2019 was $419 million, $11 million or 3% higher than in
2018. Refer to the "Net Investment Income" section of the "Consolidated Results
of Operations" discussion for a description of the factors contributing to the
Company's consolidated net investment income in 2019 as compared with the 2018.
In addition, refer to note 2 of notes to the consolidated financial statements
for a discussion of the Company's net investment income allocation methodology.

Other Revenues
Other revenues in all years presented included installment premium charges.
Claims and Expenses
Claims and Claim Adjustment Expenses
Claims and claim adjustment expenses in 2019 were $7.08 billion, $272 million or
4% lower than in 2018, primarily reflecting the impacts of (i) significantly
lower catastrophe losses and (ii) higher net favorable prior year reserve
development, partially offset by (iii) higher non-catastrophe weather-related
losses in Agency Homeowners and Other, (iv) higher business volumes and (v) loss
cost trends.

Factors contributing to net favorable prior year reserve development during the
years ended December 31, 2019 and 2018 are discussed in more detail in note 7 of
notes to the consolidated financial statements. Net prior year reserve
development in 2017 was not significant.

Amortization of Deferred Acquisition Costs
Amortization of deferred acquisition costs in 2019 was $1.62 billion, $81
million or 5% higher than in 2018, generally consistent with the increase in
earned premiums.

General and Administrative Expenses
General and administrative expenses in 2019 were $1.22 billion, $35 million or
3% higher than in 2018, primarily reflecting the impact of costs associated with
higher business volumes.

Income Tax Expense
Income tax expense in 2019 was $195 million, $153 million or 364% higher than in
2018, primarily reflecting the impacts of (i) the $680 million increase in
income before income taxes in 2019 and (ii) the reduction in income tax expense
in 2018 resulting from the Company's voluntary contribution to its qualified
domestic pension plan. The level of income tax expense in both years reflected
the impact of tax-exempt investment income on the calculation of the Company's
tax provision.

Combined Ratio
The combined ratio of 94.2% in 2019 was 6.4 points lower than the combined ratio
of 100.6% in 2018. The loss and loss adjustment expense ratio of 68.0% in 2019
was 6.1 points lower than the loss and loss adjustment expense ratio of 74.1% in
2018. The underwriting expense ratio of 26.2% in 2019 was 0.3 points lower than
the underwriting expense ratio of 26.5% in 2018.

Catastrophe losses accounted for 4.0 points and 10.7 points of the combined
ratio in 2019 and 2018, respectively. Net favorable prior year reserve
development in 2019 and 2018 provided 1.3 and 1.1 points of benefit,
respectively, to the combined ratio. The underlying combined ratio in 2019 was
0.5 points higher than the 2018 ratio on the same basis, primarily reflecting
the impacts of (i) higher non-catastrophe weather-related losses in Agency
Homeowners and Other and (ii) the impact on earned premiums related to the
Company's new catastrophe reinsurance treaty, mostly impacting Agency Homeowners
and Other, partially offset by (iii) earned pricing that exceeded loss cost
trends in Agency Automobile and (iv) a lower underwriting expense ratio.

ASBESTOS CLAIMS AND LITIGATION
The Company believes that the property and casualty insurance industry has
suffered from court decisions and other trends that have expanded insurance
coverage for asbestos claims far beyond the original intent of insurers and
policyholders. The Company has received and continues to receive a significant
number of asbestos claims. Factors underlying these claim filings include
continued intensive advertising by lawyers seeking asbestos claimants and the
focus by plaintiffs on defendants who were not traditionally primary targets of
asbestos litigation. The focus on these defendants is primarily the result of
the number of traditional asbestos defendants who have sought bankruptcy
protection in previous years.  The bankruptcy of many traditional defendants has
also caused increased settlement demands against those policyholders who are not
in bankruptcy but remain in the tort system. Currently, in many jurisdictions,
those who allege very serious injury and who can present credible medical
evidence of their injuries are receiving priority trial settings in the courts,
while those who have not shown any credible disease manifestation are having
their hearing dates delayed or placed on an inactive docket. Prioritizing claims
involving credible evidence of injuries, along with the focus on defendants who
were not traditionally primary targets of asbestos litigation, contributes to
the claims and claim adjustment expense payment patterns experienced by the
Company. The Company's asbestos-related claims and claim adjustment expense
experience also has been impacted by the unavailability of other insurance
sources potentially available to policyholders, whether through exhaustion of
policy limits or through the insolvency of other participating insurers.

The Company continues to be involved in disputes, including litigation, with a
number of policyholders, some of whom are in bankruptcy over coverage for
asbestos-related claims. Many coverage disputes with policyholders are only
resolved through settlement agreements. Because many policyholders make
exaggerated demands, it is difficult to predict the outcome of settlement
negotiations. Settlements involving bankrupt policyholders may include extensive
releases which are favorable to the Company, but which could result in
settlements for larger amounts than originally anticipated. Although the Company
has seen a reduction in the overall risk associated with these disputes, it
remains difficult to predict the ultimate cost of these claims. As in the past,
the Company will continue to pursue settlement opportunities.

In addition to claims against policyholders, proceedings have been launched
directly against insurers, including the Company, by individuals challenging
insurers' conduct with respect to the handling of past asbestos claims and by
individuals seeking damages arising from alleged asbestos-related bodily
injuries.  It is possible that the filing of other direct actions against
insurers, including the Company, could be made in the future. It is difficult to
predict the outcome of these proceedings, including whether the

                                       75
--------------------------------------------------------------------------------

plaintiffs would be able to sustain these actions against insurers based on novel legal theories of liability. The Company believes it has meritorious defenses to any such claims and has received favorable rulings in certain jurisdictions.



Because each policyholder presents different liability and coverage issues, the
Company generally reviews the exposure presented by each policyholder at least
annually.  Among the factors which the Company may consider in the course of
this review are: available insurance coverage, including the role of any
umbrella or excess insurance the Company has issued to the policyholder; limits
and deductibles; an analysis of the policyholder's potential liability; the
jurisdictions involved; past and anticipated future claim activity and loss
development on pending claims; past settlement values of similar claims;
allocated claim adjustment expense; the potential role of other insurance; the
role, if any, of non-asbestos claims or potential non-asbestos claims in any
resolution process; and applicable coverage defenses or determinations, if any,
including the determination as to whether or not an asbestos claim is a
products/completed operation claim subject to an aggregate limit and the
available coverage, if any, for that claim.

The Company categorizes its asbestos reserves as follows:

The policyholders with settlement agreements category includes certain
policyholders with whom the Company has entered into permanent settlement
agreements. Reserves in this category are based on the expected payout for each
policyholder under the applicable agreement.  The home office and field office
category relates to all other policyholders and also includes IBNR reserves and
reserves for the costs of defending asbestos-related coverage litigation. IBNR
reserves in this category include amounts for new claims and adverse development
on existing policyholders in this category, as well as reserves for claims from
policyholders reporting asbestos claims for the first time and for policyholders
for which there is, or may be, litigation. Policyholders are identified for the
annual home office review based upon, among other factors: a combination of past
payments and current case reserves in excess of a specified threshold (currently
$100,000), perceived level of exposure, number of reported claims,
products/completed operations and potential "non-product" exposures, size of
policyholder and geographic distribution of products or services sold by the
policyholder. The assumed reinsurance and other category primarily consists of
reinsurance of excess coverage, including various pool participations.

In the third quarter of 2019, the Company completed its annual in-depth asbestos
claim review, including a review of active policyholders and litigation cases
for potential product and "non-product" liability, and noted the continuation of
the following trends:
•      a high level of litigation activity in certain jurisdictions involving

individuals alleging serious asbestos-related illness, primarily involving

mesothelioma claims;

• while overall payment patterns have been generally stable, there has been

an increase in severity for certain policyholders due to the high level of

litigation activity; and

• a moderate level of asbestos-related bankruptcy activity.





In the home office and field office category, which accounts for the vast
majority of policyholders with active asbestos-related claims, the number of
policyholders with open asbestos claims and net asbestos-related payments were
comparable with 2018. Payments on behalf of policyholders in this category
continue to be influenced by a high level of litigation activity in a limited
number of jurisdictions where individuals alleging serious asbestos-related
injury, primarily mesothelioma, continue to target defendants who were not
traditionally primary targets of asbestos litigation.

The Company's quarterly asbestos reserve reviews include an analysis of exposure
and claim payment patterns by policyholder category, as well as recent
settlements, policyholder bankruptcies, judicial rulings and legislative
actions.  The Company also analyzes developing payment patterns among
policyholders in the home office and field office category and the assumed
reinsurance and other category as well as projected reinsurance billings and
recoveries.  In addition, the Company reviews its historical gross and net loss
and expense paid experience, year-by-year, to assess any emerging trends,
fluctuations or characteristics suggested by the aggregate paid activity.
Conventional actuarial methods are not utilized to establish asbestos reserves,
and the Company's evaluations have not resulted in a reliable method to
determine a meaningful average asbestos defense or indemnity payment.

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



The completion of these reviews and analyses in 2019, 2018 and 2017 resulted in
$220 million, $225 million and $225 million increases, respectively, to the
Company's net asbestos reserves. In each year, the reserve increases were
primarily driven by increases in the Company's estimate of projected settlement
and defense costs related to a broad number of policyholders in the home office
and field office category. The increase in the estimate of projected settlement
and defense costs resulted from payment trends that continue to be higher than
previously anticipated due to the impact of the current litigation environment
surrounding mesothelioma claims discussed above. Over the past decade, the
property and casualty insurance industry, including the Company, has experienced
net unfavorable prior year reserve development with regard to asbestos reserves,
but the Company believes that over that period there has been a reduction in the
volatility associated with the Company's overall asbestos exposure as the
overall asbestos environment has evolved from one dominated by exposure to
significant litigation risks, particularly coverage disputes relating to
policyholders in bankruptcy who were asserting that their claims were not
subject to the aggregate limits contained in their policies, to an environment
primarily driven by a frequency of litigation related to individuals with
mesothelioma. The Company's overall view of the current underlying asbestos
environment is essentially unchanged from recent periods, and there remains a
high degree of uncertainty with respect to future exposure to asbestos claims.
Net asbestos paid loss and loss expenses in 2019, 2018 and 2017 were $224
million, $225 million and $271 million, respectively.  Approximately 4%, 9% and
4% of total net paid losses in 2019, 2018 and 2017, respectively, related to
policyholders with whom the Company had entered into settlement agreements
limiting the Company's liability.

ENVIRONMENTAL CLAIMS AND LITIGATION
The Company has received and continues to receive claims from policyholders who
allege that they are liable for injury or damage arising out of their alleged
disposition of toxic substances. These claims are mainly brought pursuant to
various state or federal statutes that require a liable party to undertake or
pay for environmental remediation. Liability under these statutes may be joint
and several with other responsible parties.


                                       77
--------------------------------------------------------------------------------


The Company has also been, and continues to be, involved in litigation involving
insurance coverage issues pertaining to environmental claims. The Company
believes that some court decisions have interpreted the insurance coverage to be
broader than the original intent of the insurers and policyholders. These
decisions often pertain to insurance policies that were issued by the Company
prior to the mid-1980s. These decisions continue to be inconsistent and vary
from jurisdiction to jurisdiction. Environmental claims, when submitted, rarely
indicate the monetary amount being sought by the claimant from the policyholder,
and the Company does not keep track of the monetary amount being sought in those
few claims which indicate a monetary amount.

The resolution of environmental exposures by the Company generally occurs
through settlements with policyholders as opposed to claimants. Generally, the
Company strives to extinguish any obligations it may have under any policy
issued to the policyholder for past, present and future environmental
liabilities and extinguish any pending coverage litigation dispute with the
policyholder.  This form of settlement is commonly referred to as a "buy-back"
of policies for future environmental liability. In addition, many of the
agreements have also extinguished any insurance obligation which the Company may
have for other claims, including, but not limited to, asbestos and other
cumulative injury claims.  The Company and its policyholders may also agree to
settlements which only extinguish any liability arising from known specified
sites or claims.  In many instances, these agreements also include indemnities
and hold harmless provisions to protect the Company.  The Company's general
purpose in executing these agreements is to reduce the Company's potential
environmental exposure and eliminate the risks presented by coverage litigation
with the policyholder and related costs.

In establishing environmental reserves, the Company evaluates the exposure
presented by each policyholder and the anticipated cost of resolution, if any.
In the course of this analysis, the Company generally considers the probable
liability, available coverage and relevant judicial interpretations. In
addition, the Company considers the many variables presented, such as: the
nature of the alleged activities of the policyholder at each site; the number of
sites; the total number of potentially responsible parties at each site; the
nature of the alleged environmental harm and the corresponding remedy at each
site; the nature of government enforcement activities at each site; the
ownership and general use of each site; the overall nature of the insurance
relationship between the Company and the policyholder, including the role of any
umbrella or excess insurance the Company has issued to the policyholder; the
involvement of other insurers; the potential for other available coverage,
including the number of years of coverage; the role, if any, of
non-environmental claims or potential non-environmental claims in any resolution
process; and the applicable law in each jurisdiction. Conventional actuarial
methods are not used to estimate these reserves.

The Company continues to receive notices from policyholders tendering claims for
the first time, frequently under policies issued prior to the mid-1980s. These
policyholders continue to present smaller exposures, have fewer sites and are
lower-tier defendants.  Further, in many instances, clean-up costs have been
reduced because regulatory agencies are willing to accept risk-based site
analyses and more efficient clean-up technologies. Over the past several years,
the Company has experienced generally favorable trends in the number of new
policyholders tendering environmental claims for the first time and in the
number of pending declaratory judgment actions relating to environmental
matters. However, the degree to which those favorable trends have continued has
been less than anticipated. In addition, reserve development on existing
environmental claims as well as the costs associated with coverage litigation on
environmental matters have been greater than anticipated, driven by claims and
legal developments in a limited number of jurisdictions. As a result of these
factors, in 2019, 2018 and 2017, the Company increased its net environmental
reserves by $76 million, $55 million and $65 million, respectively.

At December 31, 2019, approximately 92% of the net environmental reserve
(approximately $296 million) was carried in a bulk reserve and included
unresolved environmental claims, incurred but not reported environmental claims
and the anticipated cost of coverage litigation disputes relating to these
claims. The bulk reserve the Company carries is established and adjusted based
upon the aggregate volume of in-process environmental claims and the Company's
experience in resolving those claims. The balance, approximately 8% of the net
environmental reserve (approximately $25 million), consists of case reserves.

UNCERTAINTY REGARDING ADEQUACY OF ASBESTOS AND ENVIRONMENTAL RESERVES
As a result of the processes and procedures discussed above, management believes
that the reserves carried for asbestos and environmental claims are
appropriately established based upon known facts, current law and management's
judgment. However, the uncertainties surrounding the final resolution of these
claims continue, and it is difficult to determine the ultimate exposure for
asbestos and environmental claims and related litigation. As a result, these
reserves are subject to revision as new information becomes available and as
claims develop. Changes in the legal, regulatory and legislative environment may
impact the future resolution of asbestos and environmental claims and result in
adverse loss reserve development.  The emergence of a greater number of asbestos
or environmental claims beyond that which is anticipated may result in adverse
loss reserve development. Changes in applicable legislation and future court and
regulatory decisions and interpretations, including the outcome of legal
challenges to legislative and/or judicial reforms establishing medical criteria
for the pursuit of asbestos claims, could affect the settlement of asbestos and
environmental claims. It is also difficult to predict the ultimate outcome of
complex coverage disputes until settlement negotiations near completion and
significant legal questions are resolved or, failing settlement, until the
dispute is adjudicated. This is particularly the case with policyholders in
bankruptcy where negotiations often involve a large number of claimants and
other parties and require court approval to be effective. As part of its
continuing analysis of asbestos and environmental reserves, the Company
continues to study the implications of these and other developments.

Because of the uncertainties set forth above, additional liabilities may arise
for amounts in excess of the Company's current reserves.  In addition, the
Company's estimate of claims and claim adjustment expenses may change.  These
additional liabilities or increases in estimates, or a range of either, cannot
now be reasonably estimated and could result in income statement charges that
could be material to the Company's operating results in future periods.

INVESTMENT PORTFOLIO
The Company's invested assets at December 31, 2019 were $77.88 billion, of which
94% was invested in fixed maturity and short-term investments, 1% in equity
securities, 1% in real estate investments and 4% in other investments.  Because
the primary purpose of the investment portfolio is to fund future claims
payments, the Company employs a thoughtful investment philosophy that focuses on
appropriate risk-adjusted returns. A significant majority of funds available for
investment are deployed in a widely diversified portfolio of high quality,
liquid, taxable U.S. government, tax-exempt U.S. municipal and taxable corporate
and U.S. agency mortgage-backed bonds.

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


The carrying value of the Company's fixed maturity portfolio at December 31,
2019 was $68.13 billion.  The Company closely monitors the duration of its fixed
maturity investments, and investment purchases and sales are executed with the
objective of having adequate funds available to satisfy the Company's insurance
and debt obligations.  The weighted average credit quality of the Company's
fixed maturity portfolio, both including and excluding U.S. Treasury securities,
was "Aa2" at both December 31, 2019 and 2018.  Below investment grade securities
represented 2.1% and 2.3% of the total fixed maturity investment portfolio at
December 31, 2019 and 2018, respectively.  The weighted average effective
duration of fixed maturities and short-term securities was 4.0 (4.3 excluding
short-term securities) at December 31, 2019 and 4.5 (4.7 excluding short-term
securities) at December 31, 2018. The decrease in duration compared with
December 31, 2018 primarily reflected the decrease in market interest rates
during 2019.
The carrying values of investments in fixed maturities classified as available
for sale at December 31, 2019 and 2018 were as follows:

Obligations of States, Municipalities and Political Subdivisions
The Company's fixed maturity investment portfolio at December 31, 2019 and 2018
included $29.92 billion and $28.61 billion, respectively, of securities which
are obligations of states, municipalities and political subdivisions
(collectively referred to as the municipal bond portfolio).  The municipal bond
portfolio is diversified across the United States, the District of Columbia and
Puerto Rico and includes general obligation and revenue bonds issued by states,
cities, counties, school districts and similar issuers.  Included in the
municipal bond portfolio at December 31, 2019 and 2018 were $2.06 billion and
$2.85 billion, respectively, of pre-refunded bonds, which are bonds for which
states or municipalities have established irrevocable trusts, almost exclusively
comprised of U.S. Treasury securities and obligations of U.S. government and
government agencies and authorities. These trusts were created to fund the
payment of principal and interest due under the bonds. The irrevocable trusts
are verified as to their sufficiency by an independent verification agent of the
underwriter, issuer or trustee. All of the Company's holdings of securities
issued by Puerto Rico and related entities have been pre-refunded and therefore
are defeased by U.S. Treasury securities.

(1) Rated using external rating agencies or by the Company when a public

rating does not exist. The table includes $619 million of short-term

securities which have high ratings issued by external rating agencies for


       short-term issuances.  For purposes of this table, the short-term
       securities, which are rated "A-1+" and/or "P-1," are included as "Aaa"
       rated securities.


In addition to fixed maturities noted in the foregoing table, the Company has
exposure totaling $131 million to private equity limited partnerships and real
estate partnerships (both of which are included in other investments in the
Company's consolidated balance sheet) whose primary investing focus is across
Europe.  The Company has unfunded commitments totaling $134 million to these
partnerships.  The Company has no non-redeemable preferred stock issued by
companies in the Eurozone.
Mortgage-Backed Securities, Collateralized Mortgage Obligations and Pass-Through
Securities
The Company's fixed maturity investment portfolio at December 31, 2019 and 2018
included $3.28 billion and $2.57 billion, respectively, of residential
mortgage-backed securities, including pass-through-securities and collateralized
mortgage obligations (CMOs), all of which are subject to prepayment risk (either
shortening or lengthening of duration). While prepayment risk for securities and
its effect on income cannot be fully controlled, particularly when interest
rates move dramatically, the Company's investment strategy generally favors
securities that reduce this risk within expected interest rate ranges.  The
Company makes investments in residential CMOs that are either guaranteed by
GNMA, FNMA or FHLMC, or if not guaranteed, are senior or super-senior positions
within their respective securitizations.  Both guaranteed and non-guaranteed
residential CMOs allocate the distribution of payments from the underlying
mortgages among different classes of bondholders.  In addition, non-guaranteed
residential CMOs provide structures that allocate the impact of credit losses to
different classes of bondholders.  Senior and super-senior CMOs are protected,
to varying degrees, from credit losses as those losses are initially allocated
to subordinated bondholders.  The Company's investment strategy is to purchase
CMO tranches that are expected to offer the most favorable return given the
Company's assessment of associated risks.  The Company does not purchase
residual interests in CMOs. For more information regarding the Company's
investments in residential mortgage-backed securities, see note 3 of notes to
the consolidated financial statements.

Commercial Mortgage-Backed Securities and Project Loans
At December 31, 2019 and 2018, the Company held commercial mortgage-backed
securities (including FHA project loans) of $1.51 billion and $1.22 billion,
respectively.  For more information regarding the Company's investments in
commercial mortgage-backed securities, see note 3 of notes to the consolidated
financial statements.
Equity Securities, Real Estate and Short-Term Investments
See note 1 of notes to the consolidated financial statements for further
information about these invested asset classes.
Other Investments
The Company also invests in private equity limited partnerships, hedge funds and
real estate partnerships.  Also included in other investments are non-public
common and preferred equities and derivatives.  These asset classes have
historically provided a higher return than fixed maturities but are subject to
more volatility.  At December 31, 2019 and 2018, the carrying value of the
Company's other investments was $3.42 billion and $3.56 billion, respectively.
The Company has unfunded commitments to private equity limited partnerships and
real estate partnerships in which it invests.  These commitments totaled $1.66
billion and $1.60 billion at December 31, 2019 and 2018, respectively. It is the
opinion of the Company's management that the Company has adequate liquidity to
meet these commitments.
Securities Lending
The Company has, from time to time, engaged in securities lending activities
from which it generates net investment income by lending certain of its
investments to other institutions for short periods of time.  At December 31,
2019 and 2018, the Company had $404 million and $367 million of securities on
loan, respectively, as part of a tri-party lending agreement. The average
monthly balance of securities on loan during 2019 and 2018 was $368 million and
$319 million, respectively.  Borrowers of these securities provide collateral
equal to at least 102% of the market value of the loaned securities plus accrued
interest.  The Company did not incur any investment losses in its securities
lending program for the years ended December 31, 2019 and 2018.
Lloyd's Trust Deposits
The Company meets its capital requirements to support its underwriting at
Lloyd's using a combination of the share capital and retained earnings of the
Company's subsidiaries participating in Lloyd's, trust deposits and
uncollateralized letters of credit. Securities with a fair value of
approximately $173 million and $115 million held by a wholly-owned subsidiary at
December 31, 2019 and 2018, respectively, and $34 million and $33 million held
by TRV at December 31, 2019 and 2018, respectively, were pledged into Lloyd's
trust accounts to provide a portion of the Lloyd's capital requirements. For
more information regarding the Company's utilization of uncollateralized letters
of credit, see "Liquidity and Capital Resources" herein.

Net Unrealized Investment Gains (Losses)
The net unrealized investment gains (losses) that were included in shareholders'
equity were as follows:
(at December 31, in millions)                        2019           2018           2017

) $ 1,112




The Company reported net unrealized investment gains included in shareholders'
equity at December 31, 2019 as compared to net unrealized losses at December 31,
2018. This change is due to a decline in interest rates during 2019. Equity
securities, which

                                       85
--------------------------------------------------------------------------------


include public common and non-redeemable preferred stocks, are reported at fair
value with changes in fair value recognized in net income. Prior to January 1,
2018, equity securities were classified as available for sale, and changes in
their fair value were charged or credited directly to other comprehensive
income.

At December 31, 2019, the Company had no fixed maturity investments reported at
fair value for which fair value was less than 80% of amortized cost.
For fixed maturity investments where fair value is less than the carrying value
and the Company did not reach a decision to impair, the Company continues to
have the intent and ability to hold such investments to a projected recovery in
value, which may not be until maturity.
At December 31, 2019 and 2018, below investment grade securities comprised 2.1%
and 2.3%, respectively, of the fair value of the Company's fixed maturity
investment portfolio. Included in below investment grade securities at
December 31, 2019 were securities in an unrealized loss position that, in the
aggregate, had an amortized cost of $152 million and a fair value of $146
million, resulting in a net pre-tax unrealized investment loss of $6 million.
These securities in an unrealized loss position represented less than 1% of both
the amortized cost and fair value of the fixed maturity portfolio at
December 31, 2019 and accounted for approximately 21% of the total gross pre-tax
unrealized investment loss in the fixed maturity portfolio at December 31, 2019.
Impairment Charges
Impairment charges included in net realized investment gains in the consolidated
statement of income were $4 million and $1 million for the years ended December
31, 2019 and 2018, respectively. See note 3 of notes to the consolidated
financial statements for further information.
Purchases and Sales of Investment Securities
Purchases and sales of investments are based on cash requirements, the
characteristics of the insurance liabilities and current market conditions. The
Company identifies investments to be sold to achieve its primary investment
goals of assuring the Company's ability to meet policyholder obligations as well
as to optimize investment returns, given these obligations.
During the year ended December 31, 2019, the Company incurred pre-tax realized
losses of $8 million on the sale of fixed maturity investments having a fair
value of $317 million.
CATASTROPHE MODELING
The Company uses various analyses and methods, including proprietary and
third-party computer modeling processes, to make underwriting and reinsurance
decisions designed to manage its exposure to catastrophic events. There are no
industry-standard methodologies or assumptions for projecting catastrophe
exposure. Accordingly, catastrophe estimates provided by different insurers may
not be comparable.

The Company actively monitors and evaluates changes in third-party models and,
when necessary, calibrates the catastrophe risk model estimates delivered via
its own proprietary modeling processes.  The Company considers historical loss
experience, recent events, underwriting practices, market share analyses,
external scientific analysis and various other factors, including non-modeled
losses, to refine its proprietary view of catastrophe risk. These proprietary
models are updated regularly as new information and techniques emerge.

The tables below set forth the probabilities that estimated losses, comprising
claims and allocated claim adjustment expenses (but excluding unallocated claim
adjustment expenses), from a single event occurring in a one-year timeframe will
equal or exceed the indicated loss amounts (expressed in dollars, net of tax,
and as a percentage of the Company's common equity), based on the proprietary
and third-party computer models utilized by the Company at December 31, 2019.
For example, on the basis described below the tables, the Company estimates that
there is a one percent chance that the Company's loss from a single U.S. and
Canadian hurricane in a one-year timeframe would equal or exceed $1.6 billion,
or 7% of the Company's common equity at December 31, 2019.

___________________________________________

(1) An event that has, for example, a 2% likelihood of exceedance is sometimes

described as a "1-in-50 year event." As noted above, however, the

probabilities in the table represent the likelihood of losses from a

single event equaling or exceeding the indicated threshold loss amount in

a one-year timeframe, not over a multi-year timeframe. Also, because the

probabilities relate to a single event, the probabilities do not address

the likelihood of more than one event occurring in a particular period,

and, therefore, the amounts do not address potential aggregate catastrophe

losses occurring in a one-year timeframe.

(2) The percentage of common equity is calculated by dividing (a) indicated


       loss amounts in dollars by (b) total common equity excluding net
       unrealized investment gains and losses, net of taxes, included in
       shareholders' equity. Net unrealized investment gains and losses can be

significantly impacted by both discretionary and other economic factors


       and are not necessarily indicative of operating trends. Accordingly, the
       Company's management uses the percentage of common equity calculated on
       this basis as a metric to evaluate the potential impact of a single
       hurricane or single earthquake on the Company's financial position for
       purposes of making underwriting and reinsurance decisions.


The threshold loss amounts in the tables above, which are based on the Company's
in-force portfolio at December 31, 2019 and catastrophe reinsurance program at
January 1, 2020, are net of reinsurance, after-tax and exclude unallocated claim
adjustment expenses, which historically have been less than 10% of loss
estimates. For further information regarding the Company's reinsurance, see
"Item 1-Business-Reinsurance." The amounts for hurricanes reflect U.S. and
Canadian exposures and include property exposures, property residual market
exposures and an adjustment for certain non-property exposures. The hurricane
loss amounts are based on the Company's catastrophe risk model estimates and
include losses from the hurricane hazards of wind and storm surge. The amounts
for earthquakes reflect U.S. and Canadian property and workers' compensation
exposures. The Company does not believe that the inclusion of hurricane or
earthquake losses arising from other geographical areas or other exposures would
materially change the estimated threshold loss amounts.
Catastrophe modeling relies upon inputs based on experience, science,
engineering and history.  These inputs reflect a significant amount of judgment
and are subject to changes which may result in volatility in the modeled output.
Catastrophe modeling output may also fail to account for risks that are outside
the range of normal probability or are otherwise unforeseeable. Catastrophe
modeling assumptions include, among others, the portion of purchased reinsurance
that is collectible after a catastrophic event, which may prove to be materially
incorrect. Consequently, catastrophe modeling estimates are subject to
significant uncertainty. In the tables above, the uncertainty associated with
the estimated threshold loss amounts increases significantly as the likelihood
of exceedance decreases.  In other words, in the case of a relatively more
remote event (e.g., 1-in-1,000), the estimated threshold loss amount is
relatively less reliable. Actual losses from an event could materially exceed
the indicated threshold loss amount. In addition, more than one such event could
occur in any period.

Moreover, the Company is exposed to the risk of material losses from other than
property and workers' compensation coverages arising out of hurricanes and
earthquakes, and it is exposed to catastrophe losses from perils other than
hurricanes and earthquakes, such as tornadoes and other windstorms, hail,
wildfires, severe winter weather, floods, tsunamis, volcanic eruptions, solar
flares and other naturally-occurring events, as well as acts of terrorism and
cyber events.

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


For more information about the Company's exposure to catastrophe losses, see
"Item 1A-Risk Factors-High levels of catastrophe losses, including as a result
of factors such as increased concentrations of insured exposures in
catastrophe-prone areas, could materially and adversely affect our results of
operations, our financial position and/or liquidity, and could adversely impact
our ratings, our ability to raise capital and the availability and cost of
reinsurance" and "Item 1A-Risk Factors- We may be adversely affected if our
pricing and capital models provide materially different indications than actual
results."

CHANGING CLIMATE CONDITIONS
Severe weather events over the last two decades have underscored the
unpredictability of future climate trends and created uncertainty regarding
insurers' exposures to financial loss as a result of catastrophes and other
weather-related events. The insurance industry experienced increased catastrophe
losses due to a number of potential causal factors, including, in addition to
weather/climate variability, more people living in high-risk areas, population
growth in areas with weaker enforcement of building codes, urban expansion and
an increase in the average size of a house. For example, hurricane and storm
surge activity have impacted areas further inland than previously experienced,
and demographic changes have resulted in larger populations in coastal areas
which historically have been subject to severe storms, thus expanding the
Company's potential for losses from hurricanes. Additionally, both the frequency
and severity of tornado and hail storms in the United States have been more
volatile during the last decade. The frequency and severity of wildfire losses
have been elevated in more recent years, due in part to record droughts in
California that some climate studies suggest are likely to increase over time.
Demographic changes in areas prone to wildfires have expanded the Company's
potential for losses from wildfires. Moreover, the Company's catastrophe models
may be less reliable due to the increased unpredictability in frequency and
severity of severe weather events, emerging trends in climate conditions,
inadequate reflection of regulatory changes and the other factors mentioned
above. Accordingly, the Company may be subject to increased losses from
catastrophes and other weather-related events.

The Company discusses how changing climate conditions may present other issues for its business under "Item 1A - Risk Factors" and "Outlook." For example, among other things:

• Increasingly unpredictable and severe weather conditions could result in

increased frequency and severity of claims under policies issued by the

Company. See "Item 1A-Risk Factors-High levels of catastrophe losses,

including as a result of factors such as increased concentrations of

insured exposures in catastrophe-prone areas, could materially and

adversely affect our results of operations, our financial position and/or

liquidity, and could adversely impact our ratings, our ability to raise


       capital and the availability and cost of reinsurance" and
       "-Outlook-Underwriting Gain/Loss."



•      Changing climate conditions could also impact the creditworthiness of

issuers of securities in which the Company invests. For example, water

supply adequacy could impact the creditworthiness of bond issuers with

significant assets or business activities in the Southwestern United

States, and more frequent and/or severe hurricanes could impact the

creditworthiness of issuers with significant assets or business activities

in the Southeastern United States, among other areas. See "Item 1A-Risk


       Factors-Our investment portfolio is subject to credit and interest rate
       risk, and may suffer reduced or low returns or material realized or
       unrealized losses."


• Increased regulation adopted in response to potential changes in climate

conditions may impact the Company and its customers, including state

insurance regulations that could impact the Company's ability to manage

property exposures in areas vulnerable to significant climate driven

losses. For example, a state recently passed legislation that restricts a

carrier's ability to cancel or non-renew policies within or adjacent to

declared state emergency zip codes. If the Company is unable to implement

risk-based pricing, modify policy terms or reduce exposures to the extent

necessary to address rising losses related to catastrophes and smaller

scale weather events (should those increased losses occur), its business

may be adversely affected. See "Item 1A-Risk Factors-High levels of

catastrophe losses, including as a result of factors such as increased

concentrations of insured exposures in catastrophe-prone areas, could

materially and adversely affect our results of operations, our financial

position and/or liquidity, and could adversely impact our ratings, our

ability to raise capital and the availability and cost of reinsurance." In

addition, climate change regulation could increase the Company's

customers' costs of doing business. For example, insureds faced with

carbon management regulatory requirements may have less available capital


       for investment in loss prevention and safety features which may, over
       time, increase loss exposures. Increased regulation may also result in

reduced economic activity, which would decrease the amount of insurable


       assets and businesses.


• The full range of potential liability exposures related to changing

climate conditions continues to evolve. For example, from time to time

third parties sue our policyholders alleging that they caused or

contributed to changing climate conditions. Through the Company's Emerging

Issues Committee and its Committee on Climate, Energy and the Environment,


       the Company works with its business units and corporate groups, as
       appropriate, to identify and try to assess climate change-related
       liability issues, which are continually evolving and often hard to fully

emerging issues, including changing climate conditions, to consider potential
changes to its modeling and the use of such modeling, as well as to help

At December 31, 2019, the Company held $823 million of collateral in the form of
letters of credit, funds and trust agreements held to fully or partially
collateralize certain reinsurance recoverables.
Included in total reinsurance recoverables are amounts related to structured
settlements, which are annuities purchased from various life insurance companies
to settle certain personal physical injury claims, of which workers'
compensation claims comprise a significant portion.  In cases where the Company
did not receive a release from the claimant, the amount due from the life
insurance company related to the structured settlement is included in the
Company's consolidated balance sheet as a reinsurance recoverable and the
related claim cost is included in the liability for claims and claim adjustment
expense reserves, as the Company retains the contingent liability to the
claimant.  If it is expected that the life insurance company is not able to pay,
the Company would recognize an impairment of the related reinsurance recoverable
if, and to the extent, the purchased annuities are not covered by state guaranty
associations. In the event that the life insurance company fails to make the
required annuity payments, the Company would be required to make such payments.

settlements at December 31, 2019 (in millions). Also included is the A.M. Best

The Company considers the ratings and related outlook assigned to reinsurance
companies and life insurance companies by various independent ratings agencies
in assessing the adequacy of its allowance for uncollectible amounts.
OUTLOOK

The following discussion provides outlook information for certain key drivers of the Company's results of operations and capital position.



Premiums.  The Company's earned premiums are a function of net written premium
volume.  Net written premiums comprise both renewal business and new business
and are recognized as earned premium over the life of the underlying policies.
When business renews, the amount of net written premiums associated with that
business may increase or decrease (renewal premium change) as a result of
increases or decreases in rate and/or insured exposures, which the Company
considers as a measure of units of exposure (such as the number and value of
vehicles or properties insured).  Net written premiums from both renewal and new
business, and therefore earned premiums, are impacted by competitive market
conditions as well as general economic conditions, which, particularly in the
case of Business Insurance, affect audit premium adjustments, policy
endorsements and mid-term cancellations.  Property and casualty insurance market
conditions are expected to remain competitive.  Net written premiums may also be
impacted by the structure of reinsurance programs and related costs, as well as
changes in foreign currency exchange rates.

Overall, the Company expects retention levels (the amount of expiring premium
that renews, before the impact of renewal premium changes) will remain strong by
historical standards during 2020. In Business Insurance, the Company expects
that domestic renewal premium changes for 2020 will remain positive and will be
higher than the level attained in 2019. In Bond & Specialty Insurance, the
Company expects that renewal premium changes with respect to domestic management
liability business for 2020 will remain positive and will be higher than the
level attained in 2019. In Personal Insurance, the Company expects that domestic
Agency Automobile renewal premium changes for 2020 will remain positive but will
be lower than the level attained in 2019. The Company expects that domestic
Agency Homeowners and Other renewal premium changes for 2020 will remain
positive and will be higher than the level attained in 2019. The need for state
regulatory approval for changes to personal and many commercial property and
casualty insurance prices, as well as competitive market conditions, may impact
the timing and extent of renewal premium changes. Given the relatively smaller
amount of premium that the Company generates from outside the United States and
the transactional nature of some of those markets, particularly Lloyd's,
international renewal premium changes during 2020 could be somewhat higher,
broadly consistent with or somewhat lower than the levels attained in 2019;
however, the Company expects that international renewal premium changes for the
first half of 2020 will remain positive and will be higher than the level
attained in the same period of 2019.

Property and casualty insurance market conditions are expected to remain
competitive during 2020 for new business.  In each of the Company's business
segments, new business generally has less of an impact on underwriting
profitability than renewal business, given the volume of new business relative
to renewal business.  However, in periods of meaningful increases in new
business, despite its positive impact on underwriting gains over time, the
impact of higher new business levels may negatively impact the combined ratio
for a period of time.


                                       90

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


Economic conditions in the United States and elsewhere could change due to a
variety of factors, including the political and regulatory environment, changes
to monetary policy, inflation or deflation (including the impact of rapid
changes in wages and/or commodity prices), changes in tariffs or other
international trade regulations, fluctuations in interest rates and foreign
currency exchange rates, high levels of global debt after an extended period of
low interest rates, the United Kingdom's withdrawal from the European Union, a
shutdown of the U.S. government, the failure by the U.S. government to raise the
debt ceiling, changes to the U.S. Federal budget and further potential changes
in tax laws or health care legislation in the United States. The resulting
changes in levels of economic activity could positively or negatively impact
exposure changes at renewal and the Company's ability to write business at
acceptable rates. Additionally, changes in levels of economic activity could
positively or negatively impact audit premium adjustments, policy endorsements
and mid-term cancellations after policies are written.  All of the foregoing, in
turn, could positively or negatively impact net written premiums during 2020,
and because earned premiums are a function of net written premiums, earned
premiums could be impacted on a lagging basis.

Underwriting Gain/Loss. The Company's underwriting gain/loss can be
significantly impacted by catastrophe losses and net favorable or unfavorable
prior year reserve development, as well as underlying underwriting margins.
Underlying underwriting margins can be impacted by a number of factors,
including variability in non-catastrophe weather, large loss and other loss
activity; changes in current period loss estimates resulting from prior period
loss development; changes in loss trend; changes in business mix; changes in
reinsurance coverages and/or costs; premium adjustments; and variability in
expenses and assessments.

Catastrophe losses and non-catastrophe weather-related losses are inherently
unpredictable from period to period. The Company's results of operations could
be adversely impacted if significant catastrophe and/or non-catastrophe
weather-related losses were to occur.

On average over the last ten years, the Company has experienced approximately
40% of its annual catastrophe losses during the second quarter, primarily
arising out of severe wind and hail storms, including tornadoes.  Hurricanes,
wildfires and winter storms tend to happen at other times of the year and can
also have a material impact on the Company's results of operations.  Catastrophe
losses incurred in a particular quarter in any given year may differ materially
from historical experience. In addition, most of the Company's reinsurance
programs renew on January 1 or July 1 of each year, and, therefore, any changes
to the cost or coverage terms of such programs will be effective after such
dates.

Over the past decade, the Company's results have included significant amounts of
net favorable prior year reserve development driven by better than expected loss
experience. However, given the inherent uncertainty in estimating claims and
claim adjustment expense reserves, loss experience could develop such that the
Company recognizes in future periods higher or lower levels of favorable prior
year reserve development, no favorable prior year reserve development or, as was
the case in 2019, unfavorable prior year reserve development. In addition, the
ongoing review of prior year claims and claim adjustment expense reserves, or
other changes in current period circumstances, may result in the Company
revising current year loss estimates upward or downward in future periods of the
current year.

It is possible that changes in economic conditions could lead to higher or lower
inflation than the Company had anticipated, which could in turn lead to an
increase or decrease in the Company's loss costs and the need to strengthen or
reduce claims and claim adjustment expense reserves. These impacts of inflation
on loss costs and claims and claim adjustment expense reserves could be more
pronounced for those lines of business that require a relatively longer period
of time to finalize and settle claims for a given accident year and,
accordingly, are relatively more inflation sensitive. For a further discussion,
see "Part I-Item 1A-Risk Factors-If actual claims exceed our claims and claim
adjustment expense reserves, or if changes in the estimated level of claims and
claim adjustment expense reserves are necessary, including as a result of, among
other things, changes in the legal/tort, regulatory and economic environments in
which the Company operates, our financial results could be materially and
adversely affected."

In Business Insurance, the Company expects that for 2020 in the aggregate, the
underlying underwriting margin will be higher, and the underlying combined ratio
will be lower, than in 2019, assuming the anticipated impacts of earned pricing
in excess of loss cost trends and improved results in the Company's
international business. The improvements are expected in the second through
fourth quarters of the year as a result of the timing impact of higher loss
estimates recognized in the same periods of 2019 in the general liability
product line for primary and excess coverages and in the commercial automobile
product line.

In Bond & Specialty Insurance, the Company expects that for 2020 in the aggregate, the underlying underwriting margin will be broadly consistent with 2019 and the underlying combined ratio will be slightly higher than in 2019.



In Personal Insurance, the Company expects that for 2020 in the aggregate, the
underlying underwriting margin will be higher, and the underlying combined ratio
will be lower, than in 2019. The improvements are expected in the second through
fourth quarters of the year assuming lower levels of non-catastrophe
weather-related losses. In Agency Automobile, the Company expects

                                       91
--------------------------------------------------------------------------------


that for 2020 in the aggregate, the underlying underwriting margin and the
underlying combined ratio will be broadly consistent with 2019. In Agency
Homeowners and Other, the Company expects that for 2020 in the aggregate, the
underlying underwriting margin will be higher, and the underlying combined ratio
will be lower, than in 2019. The improvements are expected in the second through
fourth quarters of the year assuming lower levels of non-catastrophe
weather-related losses.

Investment Portfolio. The Company expects to continue to focus its investment
strategy on maintaining a high-quality investment portfolio and a relatively
short average effective duration. The weighted average effective duration of
fixed maturities and short-term securities was 4.0 (4.3 excluding short-term
securities) at December 31, 2019. From time to time, the Company enters into
short positions in U.S. Treasury futures contracts to manage the duration of its
fixed maturity portfolio.  At December 31, 2019, the Company had no open U.S.
Treasury futures contracts. The Company continually evaluates its investment
alternatives and mix. Currently, the majority of the Company's investments are
comprised of a widely diversified portfolio of high-quality, liquid, taxable
U.S. government, tax-exempt U.S. municipal and taxable corporate and U.S. agency
mortgage-backed bonds.

The Company also invests much smaller amounts in equity securities, real estate,
private equity limited partnerships, hedge funds, and real estate partnerships
and joint ventures. These investment classes have the potential for higher
returns but also the potential for higher degrees of risk, including less stable
rates of return and less liquidity.

Net investment income is a material contributor to the Company's results of
operations. Based on the impact of expected lower reinvestment yields on fixed
income investments, partially offset by slightly higher levels of fixed income
investments, the Company expects that for 2020, after-tax net investment income
from that portfolio will be approximately $5 million to $10 million lower on a
quarterly basis as compared to the corresponding quarters of 2019. The impact of
future market conditions on net investment income from the Company's non-fixed
income investment portfolios for 2020 is hard to predict. If general economic
conditions and/or investment market conditions change, the Company could
experience an increase or decrease in net investment income and/or significant
realized investment gains or losses (including impairments) compared with 2019.

The Company had a net pre-tax unrealized investment gain of $2.85 billion ($2.25
billion after-tax) in its fixed maturity investment portfolio at December 31,
2019. While the Company does not attempt to predict future interest rate
movements, a rising interest rate environment would reduce the market value of
fixed maturity investments and, therefore, reduce shareholders' equity, and a
declining interest rate environment would have the opposite effects. The
Company's investment portfolio has benefited from certain tax exemptions
(primarily those related to interest from municipal bonds) and certain other tax
laws, including, but not limited to, those governing dividends-received
deductions and tax credits (such as foreign tax credits). Changes in these laws
could adversely impact the value of the Company's investment portfolio. See
"Changes in U.S. tax laws or in the tax laws of other jurisdictions in which we
operate could adversely impact us" included in "Part I-Item 1A-Risk Factors."

Portfolio." For a discussion of the risks to the Company's business during or
following a financial market disruption and risks to the Company's investment
portfolio, see the risk factors entitled "During or following a period of
financial market disruption or an economic downturn, our business could be
materially and adversely affected" and "Our investment portfolio is subject to
credit and interest rate risk, and may suffer reduced or low returns or material
realized or unrealized losses" included in "Part I-Item 1A-Risk Factors." For a
discussion of the risks to the Company's investments from foreign currency
exchange rate fluctuations, see the risk factor entitled "We are also subject to
a number of additional risks associated with our business outside the United
States" included in "Part I-Item 1A-Risk Factors" and see "Part II-Item
7A-Quantitative and Qualitative Disclosures About Market Risk-Foreign Currency
Exchange Rate Risk."

Capital Position. The Company believes it has a strong capital position and, as
part of its ongoing efforts to create shareholder value, expects to continue to
return capital not needed to support its business operations to its
shareholders. The Company expects that, generally over time, the combination of
dividends to common shareholders and common share repurchases will likely not
exceed net income. The Company also expects that to the extent that it continues
to grow premium volumes, the amount of capital returned to shareholders relative
to earnings would be somewhat less than it otherwise would have been in the
absence of such growth. The timing and actual number of shares to be repurchased
in the future will depend on a variety of factors, including the Company's
financial position, earnings, share price, catastrophe losses, maintaining
capital levels commensurate with the Company's desired ratings from independent
rating agencies, changes in levels of written premiums, funding of the Company's
qualified pension plan, capital requirements of the Company's operating
subsidiaries, legal requirements, regulatory constraints, other investment
opportunities (including mergers and acquisitions and related financings),
market conditions and other factors. For information regarding the Company's
common share repurchases in 2019, see "Liquidity and Capital Resources."

As a result of the Company's business outside of the United States, primarily in
Canada, the United Kingdom (including Lloyd's), the Republic of Ireland and in
Brazil through a joint venture, the Company's capital is also subject to the
effects of changes in foreign currency exchange rates. For example,
strengthening of the U.S. dollar in comparison to other currencies could result
in

                                       92

a reduction of shareholders' equity. For additional discussion of the Company's

I-Item 1A-Risk Factors" and "Critical Accounting Estimates."

LIQUIDITY AND CAPITAL RESOURCES
Liquidity is a measure of a company's ability to generate sufficient cash flows
to meet the cash requirements of its business operations and to satisfy general
corporate purposes when needed.
Operating Company Liquidity. The liquidity requirements of the Company's
insurance subsidiaries are met primarily by funds generated from premiums, fees,
income received on investments and investment maturities. Cash provided from
these sources is used primarily for claims and claim adjustment expense payments
and operating expenses. The insurance subsidiaries' liquidity requirements can
be impacted by, among other factors, the timing and amount of catastrophe
claims, which are inherently unpredictable, as well as the timing and amount of
reinsurance recoveries, which may be affected by reinsurer solvency and
reinsurance coverage disputes. Additionally, the variability of asbestos-related
claim payments, as well as the volatility of potential judgments and settlements
arising out of litigation, may also result in increased liquidity requirements.
It is the opinion of the Company's management that the insurance subsidiaries'
future liquidity needs will be adequately met from all of the sources described
above. Subject to restrictions imposed by states in which the Company's
insurance subsidiaries are domiciled, the Company's principal insurance
subsidiaries pay dividends to their respective parent companies, which, in turn,
pay dividends to the corporate holding (parent) company (TRV). For further
information regarding restrictions on dividends paid by the Company's insurance
subsidiaries, see "Part I-Item 1-Business-Regulation."

Holding Company Liquidity.  TRV's liquidity requirements primarily include
shareholder dividends, debt servicing, common share repurchases and, from time
to time, contributions to its qualified domestic pension plan.  At December 31,
2019, TRV held total cash and short-term invested assets in the United States
aggregating $1.43 billion and having a weighted average maturity of 53 days. TRV
has established a holding company liquidity target equal to its estimated annual
pre-tax interest expense and common shareholder dividends (currently
approximately $1.20 billion).   TRV's holding company liquidity of $1.43 billion
at December 31, 2019 exceeded this target, and it is the opinion of the
Company's management that these assets are sufficient to meet TRV's current
liquidity requirements.
TRV is not dependent on dividends or other forms of repatriation from its
foreign operations to support its liquidity needs. The undistributed earnings of
the Company's foreign operations are intended to be permanently reinvested in
those operations, and such earnings were not material to the Company's financial
position or liquidity at December 31, 2019.

TRV has a shelf registration statement filed with the Securities and Exchange
Commission that expires on June 10, 2022 which permits it to issue securities
from time to time. TRV also has a $1.0 billion line of credit facility with a
syndicate of financial institutions that expires on June 4, 2023. At
December 31, 2019, the Company had $100 million of commercial paper outstanding.
TRV is not reliant on its commercial paper program to meet its operating cash
flow needs.

The Company utilized uncollateralized letters of credit issued by major banks
with an aggregate limit of approximately $317 million to provide a portion of
the capital needed to support its obligations at Lloyd's at December 31, 2019.
If uncollateralized letters of credit are not available at a reasonable price or
at all in the future, the Company can collateralize these letters of credit or
may have to seek alternative means of supporting its obligations at Lloyd's,
which could include utilizing holding company funds on hand.

Operating Activities
Net cash flows provided by operating activities were $5.21 billion and $4.38
billion in 2019 and 2018, respectively.  The increase in cash flows in 2019
primarily reflected higher levels of cash received for (i) premiums and (ii) net
investment income, and (iii) a lower level of payments for general and
administrative expenses, partially offset by the impacts of higher levels of
payments for (iv) claims and claim adjustment expenses and (v) commission
expenses. The higher level of payments for claims and claim adjustment expenses
in 2019 included the impact of increased business volumes, partially offset by a
lower level of payments related to catastrophe losses. The lower level of
payments for general and administrative expenses reflected no voluntary

                                       93
--------------------------------------------------------------------------------


contribution to the Company's qualified domestic pension plan in 2019, compared
to a voluntary contribution of $200 million in 2018. The qualified domestic
pension plan was 108% and 109% funded at December 31, 2019 and 2018,
respectively.
Investing Activities
Net cash used in investing activities was $2.90 billion and $2.33 billion in
2019 and 2018 , respectively.  The Company's consolidated total investments at
December 31, 2019 increased by $5.61 billion, or 8% over December 31, 2018,
primarily reflecting the impacts of (i) net unrealized gains on investments at
December 31, 2019 as compared with net unrealized losses on investments at
December 31, 2018 due to a decline in interest rates during 2019 and (ii) net
cash flows provided by operating activities, partially offset by (iii) common
share repurchases and (iv) dividends paid to shareholders.
The Company's investment portfolio is managed to support its insurance
operations; accordingly, the portfolio is positioned to meet obligations to
policyholders. As such, the primary goals of the Company's asset-liability
management process are to satisfy the insurance liabilities and maintain
sufficient liquidity to cover fluctuations in projected liability cash flows.
Generally, the expected principal and interest payments produced by the
Company's fixed maturity portfolio adequately fund the estimated runoff of the
Company's insurance reserves. Although this is not an exact cash flow match in
each period, the substantial amount by which the market value of the fixed
maturity portfolio exceeds the value of the net insurance liabilities, as well
as the positive cash flow from newly sold policies and the large amount of high
quality liquid bonds, contributes to the Company's ability to fund claim
payments without having to sell illiquid assets or access credit facilities.

Financing Activities
Net cash flows used in financing activities were $2.19 billion and $2.01 billion
in 2019 and 2018, respectively.  The totals in both years primarily reflected
common share repurchases, dividends paid to shareholders and the payment of
debt, partially offset by the issuance of debt and proceeds from employee stock
option exercises. Common share repurchases in 2019 and 2018 were $1.55 billion
and $1.32 billion, respectively.
Debt Transactions.
2019. On March 4, 2019, the Company issued $500 million aggregate principal
amount of 4.10% senior notes that will mature on March 4, 2049.  The net
proceeds of the issuance, after the deduction of the underwriting discount and
expenses payable by the Company, totaled approximately $492 million.  Interest
on the senior notes is payable semi-annually in arrears on March 4 and September
4.  Prior to September 4, 2048, the senior notes may be redeemed, in whole or in
part, at the Company's option, at any time or from time to time, at a redemption
price equal to the greater of (a) 100% of the principal amount of any senior
notes to be redeemed or (b) the sum of the present values of the remaining
scheduled payments of principal and interest to but excluding September 4, 2048
on any senior notes to be redeemed (exclusive of interest accrued to the date of
redemption) discounted to the date of redemption on a semi-annual basis
(assuming a 360-day year consisting of twelve 30-day months) at the then current
Treasury rate (as defined in the senior notes), plus 20 basis points.  On or
after September 4, 2048, the senior notes may be redeemed, in whole or in part,
at the Company's option, at any time or from time to time, at a redemption price
equal to 100% of the principal amount of any senior notes to be redeemed, plus
accrued and unpaid interest to, but excluding, the redemption date.
On June 2, 2019, the Company's $500 million, 5.90% senior notes matured and were
fully paid.

2018.  On March 7, 2018, the Company issued $500 million aggregate principal
amount of 4.05% senior notes that will mature on March 7, 2048. The net proceeds
of the issuance, after the deduction of the underwriting discount and expenses
payable by the Company, totaled approximately $491 million. Interest on the
senior notes is payable semi-annually in arrears on March 7 and September 7.
Prior to September 7, 2047, the senior notes may be redeemed, in whole or in
part, at the Company's option, at any time or from time to time, at a redemption
price equal to the greater of (a) 100% of the principal amount of any senior
notes to be redeemed or (b) the sum of the present values of the remaining
scheduled payments of principal and interest to but excluding September 7, 2047
on any senior notes to be redeemed (exclusive of interest accrued to the date of
redemption) discounted to the date of redemption on a semi-annual basis
(assuming a 360-day year consisting of twelve 30-day months) at the then current
Treasury rate (as defined in the senior notes), plus 15 basis points. On or
after September 7, 2047, the senior notes may be redeemed, in whole or in part,
at the Company's option, at any time or from time to time, at a redemption price
equal to 100% of the principal amount of any senior notes to be redeemed, plus
accrued and unpaid interest to, but excluding, the redemption date.

On May 15, 2018, the Company's $500 million, 5.80% senior notes matured and were
fully paid.
Dividends.  Dividends paid to shareholders were $844 million and $814 million in
2019 and 2018 , respectively.  The declaration and payment of future dividends
to holders of the Company's common stock will be at the discretion of the
Company's Board of

                                       94
--------------------------------------------------------------------------------


Directors and will depend upon many factors, including the Company's financial
position, earnings, capital requirements of the Company's operating
subsidiaries, legal requirements, regulatory constraints and other factors as
the Board of Directors deems relevant. Dividends will be paid by the Company
only if declared by its Board of Directors out of funds legally available,
subject to any other restrictions that may be applicable to the Company. On
January 23, 2020, the Company announced that its Board of Directors declared a
regular quarterly dividend of $0.82 per share, payable March 31, 2020 to
shareholders of record on March 10, 2020.
Share Repurchases.  The Company's Board of Directors has approved common share
repurchase authorizations under which repurchases may be made from time to time
in the open market, pursuant to pre-set trading plans meeting the requirements
of Rule 10b5-1 under the Securities Exchange Act of 1934, in private
transactions or otherwise.  The authorizations do not have a stated expiration
date. The most recent authorization was approved by the Board of Directors in
April 2017 and added $5.0 billion of repurchase capacity to the $709 million
capacity remaining at that date. The Company expects that, generally over time,
the combination of dividends to common shareholders and common share repurchases
will likely not exceed net income. The Company also expects that to the extent
that it continues to grow premium volumes, the amount of capital returned to
shareholders relative to earnings would be somewhat less than it otherwise would
have been. The timing and actual number of shares to be repurchased in the
future will depend on a variety of factors, including the Company's financial
position, earnings, share price, catastrophe losses, maintaining capital levels
commensurate with the Company's desired ratings from independent rating
agencies, changes in levels of written premiums, funding of the Company's
qualified pension plan, capital requirements of the Company's operating
subsidiaries, legal requirements, regulatory constraints, other investment
opportunities (including mergers and acquisitions and related financings),
market conditions and other factors. The following table summarizes repurchase
activity in 2019 and the remaining repurchase capacity at December 31, 2019:

From the inception of the first authorization on May 2, 2006 through
December 31, 2019, the Company has repurchased a cumulative total of 508.1
million shares for a total cost of $34.21 billion, or an average of $67.34 per
share.
In both 2019 and 2018, the Company acquired 0.4 million shares of common stock
from employees as treasury stock primarily to cover payroll withholding taxes in
connection with the vesting of restricted stock unit awards and performance
share awards, and shares used by employees to cover the price of certain stock
options that were exercised.
Capital Resources
Capital resources reflect the overall financial strength of the Company and its
ability to borrow funds at competitive rates and raise new capital to meet its
needs.  The following table summarizes the components of the Company's capital
structure at December 31, 2019 and 2018:

Total capitalization at December 31, 2019 was $32.50 billion, $3.04 billion
higher than at December 31, 2018, primarily reflecting the impacts of (i)
accumulated other comprehensive income of $640 million at December 31, 2019 as
compared with an accumulated other comprehensive loss of $1.86 billion at
December 31, 2018, primarily reflecting the change in unrealized appreciation on
investments due to a decline in interest rates during 2019, (ii) net income of
$2.62 billion and (iii) proceeds from the exercise of employee share options of
$213 million, partially offset by (iv) common share repurchases totaling $1.50
billion under the Company's share repurchase authorization and (v) shareholder
dividends of $848 million.
The following table provides a reconciliation of total capitalization presented
in the foregoing table to total capitalization excluding net unrealized gains
(losses) on investments, net of taxes, included in shareholders' equity:

                                              21.7 %    

22.2 %




The debt-to-total capital ratio excluding net unrealized gains (losses) on
investments, net of taxes, included in shareholders' equity, is calculated by
dividing (a) debt by (b) total capitalization excluding net unrealized gains and
losses on investments, net of taxes, included in shareholders' equity. Net
unrealized gains and losses on investments can be significantly impacted by both
interest rate movements and other economic factors. Accordingly, in the opinion
of the Company's management, the debt-to-total capital ratio calculated on this
basis provides another useful metric for investors to understand the Company's
financial leverage position. The Company's ratio of debt-to-total capital
excluding after-tax net unrealized investment gains included in shareholders'
equity of 21.7% at December 31, 2019 was within the Company's target range of
15% to 25%.

Credit Agreement. The Company is a party to a five-year, $1.0 billion revolving
credit agreement with a syndicate of financial institutions that expires on
June 4, 2023.  Terms of the credit agreement are discussed in more detail in
note 8 of notes to the consolidated financial statements.
Shelf Registration.  The Company has filed a universal shelf registration
statement with the Securities and Exchange Commission that expires on June 10,
2022 for the potential offering and sale of securities.  The Company may offer
these securities from time to time at prices and on other terms to be determined
at the time of offering.
Share Repurchase Authorization.  At December 31, 2019, the Company had $1.79
billion of capacity remaining under its share repurchase authorization approved
by the Board of Directors.

Contractual Obligations
The following table summarizes, as of December 31, 2019, the Company's future
payments under contractual obligations and estimated claims and claim-related
payments.  The table excludes short-term obligations and includes only
liabilities at December 31, 2019 that are expected to be settled in cash.
The table below includes the amount and estimated future timing of claims and
claim-related payments. The amounts do not represent the exact liability, but
instead represent estimates, generally utilizing actuarial projection
techniques, at a given accounting date. These estimates include expectations of
what the ultimate settlement and administration of claims will cost based on the
Company's assessment of facts and circumstances known, review of historical
settlement patterns, estimates of trends in claims severity, frequency, legal
theories of liability and other factors. Variables in the reserve estimation
process can be affected by both internal and external events, such as changes in
claims handling procedures, economic inflation or deflation, legal trends and
legislative changes. Many of these items are not directly quantifiable,
particularly on a prospective basis. Additionally, there may be significant
reporting lags between the occurrence of the policyholder event and the time it
is actually reported to the insurer. The future cash flows related to the items
contained in the table below required estimation of both amount (including
severity considerations) and timing. Amount and timing are frequently estimated
separately. An estimation of both amount and timing of future cash flows related
to claims and claim-related payments has unavoidable estimation uncertainty.
The contractual obligations at December 31, 2019 were as follows:

(5) Represents estimated timing for fulfilling unfunded commitments for

private equity limited partnerships and real estate partnerships, as well


       as a put/call option entered into by the Company in connection with a
       business acquisition.

(6) The amounts in "Claims and claim adjustment expenses" in the table above

represent the estimated timing of future payments for both reported and

unreported claims incurred and related claim adjustment expenses, gross of

reinsurance recoverables, excluding structured settlements expected to be

paid by annuity companies.




The Company has entered into reinsurance agreements to manage its exposure to
losses and protect its capital as described in note 5 of notes to the
consolidated financial statements.
In order to qualify for reinsurance accounting, a reinsurance agreement must
indemnify the insurer from insurance risk, i.e., the agreement must transfer
amount and timing risk. Since the timing and amount of cash inflows from such
reinsurance agreements are directly related to the underlying payment of claims
and claim adjustment expenses by the insurer, reinsurance recoverables are
recognized in a manner consistent with the liabilities (the estimated liability
for claims and claim adjustment expenses) relating to the underlying reinsured
contracts.  The presence of any feature that can delay timely reimbursement of
claims by a reinsurer results in the reinsurance contract being accounted for as
a deposit rather than reinsurance. The assumptions used in estimating the amount
and timing of the reinsurance recoverables are consistent with those used in
estimating the amount and timing of the related liabilities.

The estimated future cash inflows from the Company's reinsurance contracts that qualify for reinsurance accounting are as follows:


                                       Less than 1       1-3       3-5      After 5
(in millions)               Total          Year         Years     Years      Years
Reinsurance recoverables   $ 5,150    $         890    $  948    $  528    $  2,784


The Company manages its business and evaluates its liabilities for claims and
claim adjustment expenses on a net of reinsurance basis.  The estimated cash
flows on a net of reinsurance basis are as follows:
                                            Less than 1         1-3            3-5          After 5
(in millions)                 Total            Year            Years          Years          Years
Claims and claim
adjustment expenses, net   $   44,889     $      10,366     $   11,603     $    5,326     $   17,594


For business underwritten by non-U.S. operations, future cash flows related to
reported and unreported claims incurred and related claim adjustment expenses
were translated at the spot rate on December 31, 2019.
The amounts reported in the table above and in the table of reinsurance
recoverables above are presented on a nominal basis and have not been adjusted
to reflect the time value of money. Accordingly, the amounts above will differ
from the Company's balance sheet to the extent that the liability for claims and
claim adjustment expenses and the related reinsurance recoverables have been
discounted in the balance sheet. See note 1 of notes to the consolidated
financial statements.
(7)    Workers' compensation large deductible policies provide third-party
       coverage in which the Company typically is responsible for paying the
       entire loss under such policies and then seeks reimbursement from the

insured for the deductible amount. "Claims from large deductible policies"

represent the estimated future payment for claims and claim related

expenses below the deductible amount, net of the estimated recovery of the

deductible. The liability and the related deductible receivable for unpaid

claims are presented in the consolidated balance sheet as "contractholder

payables" and "contractholder receivables," respectively. Most deductibles


       for such policies are paid directly from the policyholder's escrow, which
       is periodically replenished by the policyholder. The payment of the loss
       amounts above the deductible are reported within "Claims and claim
       adjustment expenses" in the above table. Because the timing of the

collection of the deductible (contractholder receivables) occurs shortly

after the payment of the deductible to a claimant (contractholder

payables), these cash flows offset each other in the table.




The estimated timing of the payment of the contractholder payables and the
collection of contractholder receivables for workers' compensation policies is
presented below:
                                                  Less than 1       1-3        3-5      After 5
(in millions)                          Total          Year         Years      Years      Years
Contractholder payables/receivables   $ 4,619    $       1,261    $ 1,316    $  676    $  1,366



                                       98

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

(8) The amounts in "Loss-based assessments" relate to estimated future

payments of second-injury fund assessments which would result from payment


       of current claim liabilities. Second injury funds cover the cost of any
       additional benefits for aggravation of a pre-existing condition. For
       loss-based assessments, the cost is shared by the insurance industry and
       self-insureds, funded through assessments to insurance companies and
       self-insureds based on losses. Amounts relating to second-injury fund
       assessments are included in "other liabilities" in the consolidated
       balance sheet.

(9) The amounts in "Reinsurance contracts accounted for as deposits" represent


       estimated future nominal payments for reinsurance agreements that are
       accounted for as deposits. Amounts payable under deposit agreements are
       included in "other liabilities" in the consolidated balance sheet.

(10) The amounts in "Payout from ceded funds withheld" represent estimated

payments for losses and return of funds held related to certain

reinsurance arrangements whereby the Company holds a portion of the

premium due to the reinsurer and is allowed to pay claims from the amounts

held.

(11) The Company's current liabilities related to unrecognized tax benefits

from uncertain tax positions are $50 million. Offsetting these liabilities

are deferred tax assets of $5 million associated with the temporary

differences that would exist if these positions become realized.




The above table does not include an analysis of liabilities reported for
structured settlements for which the Company has purchased annuities and remains
contingently liable in the event of default by the company issuing the annuity.
The Company is not reasonably likely to incur material future payment
obligations under such agreements. In addition, the Company is not currently
subject to any minimum funding requirements for its qualified pension plan.
Accordingly, future contributions are not included in the foregoing table.

Dividend Availability
The Company's principal insurance subsidiaries are domiciled in the State of
Connecticut. The insurance holding company laws of Connecticut applicable to the
Company's subsidiaries requires notice to, and approval by, the state insurance
commissioner for the declaration or payment of any dividend that, together with
other distributions made within the preceding twelve months, exceeds the greater
of 10% of the insurer's statutory capital and surplus as of the preceding
December 31, or the insurer's net income for the twelve-month period ending the
preceding December 31, in each case determined in accordance with statutory
accounting practices and by state regulation. This declaration or payment is
further limited by adjusted unassigned surplus, as determined in accordance with
statutory accounting practices. The insurance holding company laws of other
states in which the Company's subsidiaries are domiciled generally contain
similar, although in some instances somewhat more restrictive, limitations on
the payment of dividends. A maximum of $2.79 billion is available by the end of
2020 for such dividends to the holding company, TRV, without prior approval of
the Connecticut Insurance Department. The Company may choose to accelerate the
timing within 2020 and/or increase the amount of dividends from its insurance
subsidiaries in 2020, which could result in certain dividends being subject to
approval by the Connecticut Insurance Department.

In addition to the regulatory restrictions on the availability of dividends that
can be paid by the Company's U.S. insurance subsidiaries, the maximum amount of
dividends that may be paid to the Company's shareholders is limited, to a lesser
degree, by certain covenants contained in its line of credit agreement with a
syndicate of financial institutions that require the Company to maintain a
minimum consolidated net worth as described in note 8 of notes to the
consolidated financial statements.

TRV is not dependent on dividends or other forms of repatriation from its
foreign operations to support its liquidity needs. The undistributed earnings of
the Company's foreign operations are intended to be permanently reinvested in
those operations, and such earnings were not material to the Company's financial
position or liquidity at December 31, 2019.

TRV and its two non-insurance holding company subsidiaries received dividends of
$2.50 billion and $2.30 billion from their U.S. insurance subsidiaries in 2019
and 2018, respectively.
Pension and Other Postretirement Benefit Plans
The Company sponsors a qualified non-contributory defined benefit pension plan
(the Qualified Plan), which covers substantially all U.S. domestic employees and
provides benefits primarily under a cash balance formula. In addition, the
Company sponsors a nonqualified defined benefit pension plan which covers
certain highly-compensated employees, pension plans for employees of its foreign
subsidiaries, and a postretirement health and life insurance benefit plan for
employees satisfying certain age and service requirements and for certain
retirees.


                                       99
--------------------------------------------------------------------------------


The Qualified Plan is subject to regulations under the Employee Retirement
Income Security Act of 1974 as amended (ERISA), which requires plans to meet
minimum standards of funding and requires such plans to subscribe to plan
termination insurance through the Pension Benefit Guaranty Corporation (PBGC).
The Company does not have a minimum funding requirement for the Qualified Plan
for 2020 and does not anticipate having a minimum funding requirement in 2021.
The Company has significant discretion in making contributions above those
necessary to satisfy the minimum funding requirements. In 2019, 2018 and 2017,
there was no minimum funding requirement for the Qualified Plan.  In 2019, the
Company made no voluntary contributions to the Qualified Plan. In 2018 and 2017,
the Company voluntarily made contributions totaling $200 million and $300
million, respectively, to the Qualified Plan.  Based on its funded status at
December 31, 2019, the Company does not currently anticipate making a voluntary
contribution to the Qualified Plan in 2020. In determining future contributions,
the Company will consider the performance of the plan's investment portfolio,
the effects of interest rates on the projected benefit obligation of the plan
and the Company's other capital requirements.

The Qualified Plan assets are managed to maximize long-term total return while
maintaining an appropriate level of risk. The Company's overall strategy is to
achieve a mix of approximately 85% to 90% of investments for long-term growth
and 10% to 15% for near-term benefit payments with a diversification of asset
types, fund strategies and fund managers. The current target allocations for
plan assets are 55% to 65% equity securities and 20% to 40% fixed income
securities, with the remainder allocated to short-term securities. For 2020, the
Company plans to apply an expected long-term rate of return on plan assets of
6.75%, compared with 7.00% in 2019. The expected rate of return reflects the
Company's current expectations with regard to long-term returns in the capital
markets, taking into account the pension plan's asset allocation targets, the
historical performance and current valuation of U.S. and international equities,
and the level of long term interest rate and inflation expectations.  The
decrease in the expected long-term rate of return on plan assets to 6.75% for
2020 primarily reflects the Company's current expectations with regard to
long-term interest rates in the future.

For further discussion of the pension and other postretirement benefit plans,
see note 14 of notes to the consolidated financial statements.
Risk-Based Capital
The NAIC has an RBC requirement for most property and casualty insurance
companies, which determines minimum capital requirements and is intended to
raise the level of protection for policyholder obligations. The Company's U.S.
insurance subsidiaries are subject to these NAIC RBC requirements based on laws
that have been adopted by individual states. These requirements subject insurers
having policyholders' surplus less than that required by the RBC calculation to
varying degrees of regulatory action, depending on the level of capital
inadequacy. Each of the Company's U.S. insurance subsidiaries had policyholders'
surplus at December 31, 2019 significantly above the level at which any RBC
regulatory action would occur.  Regulators in the jurisdictions in which the
Company's foreign insurance subsidiaries are located require insurance companies
to maintain certain levels of capital depending on, among other things, the type
and amount of insurance policies written.  Each of the Company's foreign
insurance subsidiaries had capital significantly above their respective
regulatory requirements at December 31, 2019.

Off-Balance Sheet Arrangements
The Company has entered into certain contingent obligations for guarantees
related to selling businesses to third parties, certain investments, certain
insurance policy obligations of former insurance subsidiaries and various other
indemnifications. See note 16 of notes to the consolidated financial statements.
The Company does not expect these arrangements will have a material effect on
the Company's financial position, changes in financial position, revenues and
expenses, results of operations, liquidity, capital expenditures or capital
resources.

CRITICAL ACCOUNTING ESTIMATES
The Company considers its most significant accounting estimates to be those
applied to claims and claim adjustment expense reserves and related reinsurance
recoverables, investment valuation and impairments, and goodwill and other
intangible assets impairments.

The $1.18 billion increase in gross claims and claim adjustment expense reserves
since December 31, 2018 primarily reflected the impacts of higher volumes of
insured exposures and loss cost trends for the current accident year.

Asbestos and environmental reserves are included in the General liability,
Commercial multi-peril and International and other lines in the foregoing
summary table. Asbestos and environmental reserves are discussed separately; see
"Asbestos Claims and Litigation", "Environmental Claims and Litigation" and
"Uncertainty Regarding Adequacy of Asbestos and Environmental Reserves."
Claims and claim adjustment expense reserves represent management's estimate of
the ultimate liability for unpaid losses and loss adjustment expenses for claims
that have been reported and claims that have been incurred but not yet reported
(IBNR) as of the balance sheet date. Claims and claim adjustment expense
reserves do not represent an exact calculation of liability, but instead
represent management estimates, primarily utilizing actuarial expertise and
projection methods. These estimates are expectations of what the ultimate
settlement and administration of claims will cost upon final resolution in the
future, based on the Company's assessment of facts and circumstances then known,
review of historical settlement patterns, estimates of trends in claims severity
and frequency, expected interpretations of legal theories of liability and other
factors. In establishing gross claims and claim adjustment expense reserves, the
Company also considers salvage and subrogation. Estimated recoveries from
reinsurance are included in "Reinsurance Recoverables" as an asset on the
Company's consolidated balance sheet. The claims and claim adjustment expense
reserves are reviewed regularly by qualified actuaries employed by the Company.

The process of estimating claims and claim adjustment expense reserves involves
a high degree of judgment and is subject to a number of variables. These
variables can be affected by both internal and external events, such as changes
in claims handling procedures, changes in individuals involved in the reserve
estimation process, economic inflation, changes in the tort environment, legal
trends and legislative changes, among others. The impact of many of these items
on ultimate costs for claims and claim adjustment expenses is difficult to
estimate. Estimation difficulties also differ significantly by product line due
to differences in claim complexity, the volume of claims, the potential severity
of individual claims, the determination of occurrence date for a claim and
reporting lags (the time between the occurrence of the policyholder event and
when it is actually reported to the insurer). Informed judgment is applied
throughout the process, including the application of various individual
experiences and expertise to multiple sets of data and analyses. The Company
continually refines its estimates in a regular ongoing process as historical
loss experience develops and additional claims are reported and settled. The
Company rigorously attempts to consider all significant facts and circumstances
known at the time claims and claim adjustment expense reserves are established.
Due to the inherent uncertainty underlying these estimates including, but not
limited to, the future settlement environment, final resolution of the estimated
liability for claims and claim adjustment expenses may be higher or lower than
the related claims and claim adjustment expense reserves at the reporting date.
Therefore, actual paid losses, as claims are settled in the future, may be
materially different than the amount currently recorded-favorable or
unfavorable.

                                      101
--------------------------------------------------------------------------------

Because establishment of claims and claim adjustment expense reserves is an inherently uncertain process involving estimates and the application of judgment, currently established claims and claim adjustment expense reserves may change. The Company reflects adjustments to the reserves in the results of operations in the period the estimates are changed.



There are also additional risks which impact the estimation of ultimate costs
for catastrophes. For example, the estimation of reserves related to hurricanes,
tornadoes, wildfires and other catastrophic events can be affected by the
inability of the Company and its insureds to access portions of the impacted
areas, the complexity of factors contributing to the losses, the legal and
regulatory uncertainties, including the interpretation of policy terms and
conditions, and the nature of the information available to establish the
reserves. Complex factors include, but are not limited to: determining whether
damage was caused by flooding versus wind; evaluating general liability and
pollution exposures; estimating additional living expenses; estimating the
impact of demand surge, infrastructure disruption, fraud, the effect of mold
damage and business interruption costs; and reinsurance collectibility. The
timing of a catastrophe, such as at or near the end of a reporting period, can
also affect the information available to the Company in estimating reserves for
that reporting period. The estimates related to catastrophes are adjusted as
actual claims emerge.

A portion of the Company's gross claims and claim adjustment expense reserves
(totaling $1.95 billion at December 31, 2019) are for asbestos and environmental
claims and related litigation. While the ongoing review of asbestos and
environmental claims and associated liabilities considers the inconsistencies of
court decisions as to coverage, plaintiffs' expanded theories of liability and
the risks inherent in complex litigation and other uncertainties, in the opinion
of the Company's management, it is possible that the outcome of the continued
uncertainties regarding these claims could result in liability in future periods
that differs from current insurance reserves by an amount that could be material
to the Company's future operating results. See the preceding discussion of
"Asbestos Claims and Litigation" and "Environmental Claims and Litigation."
General Discussion
The process for estimating the liabilities for claims and claim adjustment
expenses begins with the collection and analysis of claim data. Data on
individual reported claims, both current and historical, including paid amounts
and individual claim adjuster estimates, are grouped by common characteristics
(components) and evaluated by actuaries in their analyses of ultimate claim
liabilities. Such data is occasionally supplemented with external data as
available and when appropriate. The process of analyzing reserves for a
component is undertaken on a regular basis, generally quarterly, in light of
continually updated information.

Multiple estimation methods are available for the analysis of ultimate claim
liabilities. Each estimation method has its own set of assumption variables and
its own advantages and disadvantages, with no single estimation method being
better than the others in all situations and no one set of assumption variables
being meaningful for all product line components. The relative strengths and
weaknesses of the particular estimation methods when applied to a particular
group of claims can also change over time. Therefore, the actual choice of
estimation method(s) can change with each evaluation. The estimation method(s)
chosen are those that are believed to produce the most reliable indication at
that particular evaluation date for the claim liabilities being evaluated.

In most cases, multiple estimation methods will be valid for the particular
facts and circumstances of the claim liabilities being evaluated. This will
result in a range of reasonable estimates for any particular claim liability.
The Company uses such range analyses to back test whether previously established
estimates for reserves by reporting segments are reasonable, given available
information. Reported values found to be closer to the endpoints of a range of
reasonable estimates are subject to further detailed reviews. These reviews may
substantiate the validity of management's recorded estimate or lead to a change
in the reported estimate.

The exact boundary points of these ranges are more qualitative than quantitative
in nature, as no clear line of demarcation exists to determine when the set of
underlying assumptions for an estimation method switches from being reasonable
to unreasonable. As a result, the Company does not believe that the endpoints of
these ranges are or would be comparable across companies. In addition, potential
interactions among the different estimation assumptions for different product
lines make the aggregation of individual ranges a highly judgmental and inexact
process.

Property-casualty insurance policies are either written on a "claims-made" or on
an "occurrence" basis. Claims-made policies generally cover, subject to
requirements in individual policies, claims reported during the policy period.
Policies that are written on an occurrence basis require that the insured
demonstrate that a loss occurred in the policy period, even if the insured
reports the loss many years later.

Most general liability policies are written on an occurrence basis. These policies are subject to substantial loss development over time as facts and circumstances change in the years following the policy issuance. The occurrence form, which accounts for much of the reserve development in asbestos and environmental exposures, is also used to provide coverage for construction general


                                      102
--------------------------------------------------------------------------------


liability, including construction defect. Occurrence-based forms of insurance
for general liability exposures require substantial projection of loss trends,
which can be influenced by a number of factors, including future inflation,
judicial interpretations and societal litigation trends (e.g., size of jury
awards and propensity of individuals to pursue litigation), among others.

A basic premise in most actuarial analyses is that past patterns demonstrated in
the data will repeat themselves in the future, absent a material change in the
associated risk factors discussed below. To the extent a material change
affecting the ultimate claim liability is known, such change is estimated to the
extent possible through an analysis of internal company data and, if available
and when appropriate, external data. Such a measurement is specific to the facts
and circumstances of the particular claim portfolio and the known change being
evaluated. Significant structural changes to the available data, product mix or
organization can materially impact the reserve estimation process. In addition,
the introduction of new products creates a unique risk as historical company
data would typically not be available.

Informed judgment is applied throughout the reserving process. This includes the
application of various individual experiences and expertise to multiple sets of
data and analyses. In addition to actuaries, experts involved with the reserving
process also include underwriting and claims personnel and lawyers, as well as
other company management. Therefore, management may have to consider varying
individual viewpoints as part of its estimation of claims and claim adjustment
expense reserves. It is also likely that during periods of significant change,
such as a merger, consistent application of informed judgment becomes even more
complicated and difficult.

The variables discussed above in this general discussion have different impacts
on reserve estimation uncertainty for a given product line, depending on the
length of the claim tail, the reporting lag, the impact of individual claims and
the complexity of the claim process for a given product line.

Product lines are generally classifiable as either long tail or short tail,
based on the average length of time between the event triggering claims under a
policy and the final resolution of those claims. Short tail claims are reported
and settled quickly, resulting in less estimation variability. The longer the
time to final claim resolution, the greater the exposure to estimation risks and
hence the greater the estimation uncertainty.

A major component of the claim tail is the reporting lag. The reporting lag,
which is the time between the event triggering a claim and the reporting of the
claim to the insurer, makes estimating IBNR inherently more uncertain. In
addition, the greater the reporting lag, the greater the proportion of IBNR to
the total claim liability for the product line. Writing new products with
material reporting lags can result in adding several years' worth of IBNR claim
exposure before the reporting lag exposure becomes clearly observable, thereby
increasing the risk associated with estimating the liabilities for claims and
claim adjustment expenses for such products. The most extreme example of claim
liabilities with long reporting lags are asbestos claims.

For some lines, the impact of large individual claims can be material to the
analysis. These lines are generally referred to as being "low frequency/high
severity," while lines without this "large claim" sensitivity are referred to as
"high frequency/low severity." Estimates of claim liabilities for low
frequency/high severity lines can be sensitive to the impact of a small number
of potentially large claims. As a result, the role of judgment is much greater
for these reserve estimates. In contrast, for high frequency/low severity lines
the impact of individual claims is relatively minor and the range of reasonable
reserve estimates is likely narrower and more stable.

Claim complexity can also greatly affect the estimation process by impacting the
number of assumptions needed to produce the estimate, the potential stability of
the underlying data and claim process, and the ability to gain an understanding
of the data. Product lines with greater claim complexity, such as for certain
surety and construction exposures, have inherently greater estimation
uncertainty.

Actuaries have to exercise a considerable degree of judgment in the evaluation
of all these factors in their analysis of reserves. The human element in the
application of actuarial judgment is unavoidable when faced with material
uncertainty. Different actuaries may choose different assumptions when faced
with such uncertainty, based on their individual backgrounds, professional
experiences and areas of focus. Hence, the estimates selected by the various
actuaries may differ materially from each other.

Lastly, significant structural changes to the available data, product mix or
organization can also materially impact the reserve estimation process. Events
such as mergers increase the inherent uncertainty of reserve estimates for a
period of time, until stable trends re-establish themselves within the new
organization.


                                      103
--------------------------------------------------------------------------------


Risk Factors
The major causes of material uncertainty ("risk factors") generally will vary
for each product line, as well as for each separately analyzed component of the
product line. In a few cases, such risk factors are explicit assumptions of the
estimation method, but in most cases, they are implicit. For example, a method
may explicitly assume that a certain percentage of claims will close each year,
but will implicitly assume that the legal interpretation of existing contract
language will remain unchanged. Actual results will likely vary from
expectations for each of these assumptions, causing actual paid losses, as
claims are settled in the future, to be different in amount than the reserves
being estimated currently.

Some risk factors will affect more than one product line. Examples include
changes in claim department practices, changes in the tort environment, changes
in settlement patterns, regulatory and legislative actions, court actions,
timeliness of claim reporting, state mix of claimants and degree of claimant
fraud. The extent of the impact of a risk factor will also vary by components
within a product line. Individual risk factors are also subject to interactions
with other risk factors within product line components.

The effect of a particular risk factor on estimates of claim liabilities cannot
be isolated in most cases. For example, estimates of potential claim settlements
may be impacted by the risk associated with potential court rulings, but the
final settlement agreement typically does not delineate how much of the settled
amount is due to this and other factors.

The evaluation of data is also subject to distortion from extreme events or
structural shifts, sometimes in unanticipated ways. For example, the timing of
claims payments in one geographic region may be impacted if claim adjusters are
temporarily reassigned from that region to help settle catastrophe claims in
another region.

While some changes in the claim environment are sudden in nature (such as a new
court ruling affecting the interpretation of all contracts in that
jurisdiction), others are more evolutionary. Evolutionary changes can occur when
multiple factors affect final claim values, with the uncertainty surrounding
each factor being resolved separately, in stepwise fashion. The final impact is
not known until all steps have occurred.

Sudden changes generally cause a one-time shift in claim liability estimates, although there may be some lag in reliable quantification of their impact. Evolutionary changes generally cause a series of shifts in claim liability estimates, as each component of the evolutionary change becomes evident and estimable.



Actuarial Methods for Analyzing and Estimating Claims and Claim Adjustment
Expense Reserves
The principal estimation and analysis methods utilized by the Company's
actuaries to evaluate management's existing estimates for prior accident periods
are the paid loss development method, the case incurred development method, the
Bornhuetter-Ferguson (BF) method, and average value analysis combined with the
reported claim development method. The BF method is usually utilized for more
recent accident periods, with a transition to other methods as the underlying
claim data becomes more voluminous and therefore more credible. These estimation
and analysis methods are typically referred to as conventional actuarial
methods. (See note 7 of notes to the consolidated financial statements for an
explanation of these methods).

While the Company utilizes these conventional actuarial methods to estimate the
claims liability for its various businesses, Company actuaries evaluating a
particular component for a product line may select from the full range of
methods developed within the casualty actuarial profession. The Company's
actuaries are also continually monitoring developments within the profession for
advances in existing techniques or the creation of new techniques that might
improve current and future estimates.

Some components of a product line may be susceptible to infrequent large claims or not be subject to conventional methods. In such cases, the Company's actuarial analysis will isolate such components for review. The reserves excluding such large claims are generally analyzed using the conventional methods described above. The reserves associated with large claims are then analyzed utilizing various methods, such as:

• Estimating the number of large claims and their average values based on

historical trends from prior accident periods, adjusted for the current


       environment and supplemented with actual data for the accident year
       analyzed to the extent available.


•      Utilizing individual claim adjuster estimates of the large claims,
       combined with continual monitoring of the aggregate accuracy of such claim

adjuster estimates. (This monitoring may lead to supplemental adjustments

to the aggregate of such claim estimates).

• Utilizing historic longer-term average ratios of large claims to small

claims, and applying such ratios to the estimated ultimate small claims

from conventional analysis.

• Ground-up analysis of the underlying exposure (typically used for asbestos


       and environmental).



                                      104

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



The results of such methodologies are subjected to various reasonability and
diagnostic tests, including implied incurred-loss-to-earned-premium ratios,
non-zero claim severity trends and paid-to-incurred loss ratios. An actual
versus expected analysis is also performed comparing actual loss development to
expected development embedded within management's estimate. Additional analyses
may be performed based on the results of these diagnostics, including the
investigation of other actuarial methods.

The methods described above are generally utilized to evaluate management's
estimate for prior accident periods. For the initial estimate of the current
accident year, however, the available claim data is typically insufficient to
produce a reliable indication. As a result, the initial estimate for an accident
year is generally based on an exposure-based method using either the loss ratio
projection method or the expected loss method. The loss ratio projection method,
which is typically used for guaranteed-cost business, develops an initial
estimate for an accident year by multiplying earned premiums for the accident
year by a projected loss ratio. The projected loss ratio is determined by
analyzing prior period experience, and adjusting for loss cost trends, rate
level differences, mix of business changes and other known or observed factors
influencing the current accident year relative to prior accident years. The
exact number of prior accident years utilized varies by product line component,
based on the stability and consistency of the individual accident year
estimates. The expected loss method, which is typically used for loss sensitive
business, develops an initial estimate of ultimate claims and claim adjustment
expenses for an accident year by analyzing exposures by account.

Management's Estimates
At least once per quarter, certain members of Company management meet with the
Company's actuaries to review the latest claims and claim adjustment expense
reserve analyses. Based on these analyses, management determines whether its
ultimate claim liability estimates should be changed from the prior period. In
doing so, it must evaluate whether the new data provided represents credible
actionable information or an anomaly that will have no effect on estimated
ultimate claim liability. For example, as described above, payments may have
decreased in one geographic region due to fewer claim adjusters being available
to process claims. The resulting claim payment patterns would be analyzed to
determine whether or not the change in payment pattern represents a change in
ultimate claim liability.

Such an assessment requires considerable judgment. It is frequently not possible
to determine whether a change in the data is an anomaly until sometime after the
event. Even if a change is determined to be permanent, it is not always possible
to reliably determine the extent of the change until sometime later. The overall
detailed analyses supporting such an effort can take several months to perform
as the underlying causes of the trends observed need to be evaluated, which may
require the gathering or assembling of data not previously available. It may
also include interviews with experts involved with the underlying processes. As
a result, there can be a time lag between the emergence of a change and a
determination that the change should be reflected in the Company's estimated
claim liabilities. The final estimate selected by management in a reporting
period is based on these various detailed analyses of past data, adjusted to
reflect any new actionable information.

The Audit Committee of the Board of Directors reviews the process by which the Company establishes reserves for the purpose of the Company's financial statements.



Discussion of Product Lines
The following section details reserving considerations and common risk factors
by product line. There are many additional risk factors that may impact ultimate
claim costs. Each risk factor presented will have a different impact on required
reserves. Also, risk factors can have offsetting or compounding effects on
required reserves. For example, in workers' compensation, the use of expensive
medical procedures that result in medical cost inflation may enable workers to
return to work faster, thereby lowering indemnity costs. Thus, in almost all
cases, it is impossible to discretely measure the effect of a single risk factor
and construct a meaningful sensitivity expectation.

In order to provide information on reasonably possible reserving changes by
product line, the historical changes in year-end claims and claim adjustment
expense reserves over a one-year period are provided for the U.S. product lines.
This information is provided for both the Company and the industry for the nine
most recent years, and is based on the most recent publicly available data for
the reported line(s) that most closely match the individual product line being
discussed. These changes were calculated, net of reinsurance, from statutory
annual statement data found in Schedule P of those statements, and represent the
reported reserve development on the beginning-of-the-year claim liabilities
divided by the beginning claim liabilities, all accident years combined,
excluding non-defense related claim adjustment expense. Data presented for the
Company includes history for the entire Travelers group (U.S. companies only),
as required by the statutory reporting instructions promulgated by state
regulatory authorities for Schedule P. Comparable data for non-U.S. companies is
not available.

General Liability
General liability is generally considered a long tail line, as it takes a
relatively long period of time to finalize and settle claims from a given
accident year. The speed of claim reporting and claim settlement is a function
of the characteristics of claims, including specific coverage provided, the
jurisdiction and specific policy provisions such as self-insured retentions,
among others. There are numerous components underlying the general liability
product line. Some of these have relatively moderate payment patterns (with most
of the claims for a given accident year closed within five to seven years),
while others can have extreme lags in both reporting and payment of claims
(e.g., a reporting lag of a decade or more for "construction defect" claims).

While the majority of general liability coverages are written on an "occurrence"
basis, certain general liability coverages (such as those covering management
and professional liability, including cyber coverages) are typically insured on
a "claims-made" basis.

General liability reserves are generally analyzed as two components: primary and
excess/umbrella, with the primary component generally analyzed separately for
bodily injury and property damage. Bodily injury liability payments reimburse
the claimant for damages pertaining to physical injury as a result of the
policyholder's legal obligation arising from non-intentional acts such as
negligence, subject to the insurance policy provisions. In some cases the
damages can include future wage loss (which is a function of future earnings
power and wage inflation) and future medical treatment costs. Property damage
liability payments result from damages to the claimant's private property
arising from the policyholder's legal obligation for non-intentional acts. In
most cases, property damage losses are a function of costs as of the loss date,
or soon thereafter.

In addition, sizable or unique exposures are reviewed separately. These exposures include asbestos, environmental, other mass torts, construction defect and large unique accounts that would otherwise distort the analysis. These unique categories often require a very high degree of judgment and require reserve analyses that do not rely on conventional actuarial methods.



Defense costs are also a part of the insured costs covered by liability policies
and can be significant, sometimes greater than the cost of the actual paid
claims. For some products this risk is mitigated by policy language such that
the insured portion of defense costs is included in the policy limit available
to pay the claim. Such "defense within the limits" policies are most common for
"claims-made" products. When defense costs are outside of the policy limits, the
full amount of the policy limit is available to pay claims and the amounts paid
for defense costs have no contractual limit.

This line is typically the largest source of reserve estimate uncertainty in the
United States (excluding assumed reinsurance contracts covering the same risk).
Major contributors to this reserve estimate uncertainty include the reporting
lag (i.e., the length of time between the event triggering coverage and the
actual reporting of the claim), the number of parties involved in the underlying
tort action, whether the "event" triggering coverage is confined to only one
time period or is spread over multiple time periods, the potential dollars
involved (in the individual claim actions), whether such claims were reasonably
foreseeable and intended to be covered at the time the contracts were written
(i.e., coverage dispute potential), and the potential for mass claim actions.
Claims with longer reporting lags result in greater estimation uncertainty. This
is especially true for alleged claims with a latency feature, particularly where
courts have ruled that coverage is spread over multiple policy years, hence
involving multiple defendants (and their insurers and reinsurers) and multiple
policies (thereby increasing the potential dollars involved and the underlying
settlement complexity). Claims with long latencies also increase the potential
recognition lag (i.e., the lag between writing a type of policy in a certain
market and the recognition that such policies have potential mass tort and/or
latent claim exposure).

The amount of reserve estimate uncertainty also varies significantly by
component for the general liability product line. The components in this product
line with the longest latency, longest reporting lags, largest potential dollars
involved and greatest claim settlement complexity are asbestos and
environmental. Components that include latency, reporting lag and/or complexity
issues, but to a materially lesser extent than asbestos and environmental,
include construction defect and other mass tort actions. Many components of
general liability are not subject to material latency or claim complexity risks
and hence have materially less uncertainty than the previously mentioned
components. In general, components with shorter reporting lags, fewer parties
involved in settlement negotiations, only one policy potentially triggered per
claim, fewer potential settlement dollars, reasonably foreseeable (and stable)
potential hazards/claims and no mass tort potential result in much less reserve
estimate uncertainty than components without those characteristics.

In addition to the conventional actuarial methods mentioned in the general
discussion section, the company utilizes various report year development methods
for the construction defect components of this product line. The Construction
Defect report year development analysis is supplemented with projected claim
counts and average values for IBNR claim counts. For components with greater
lags in claim reporting, such as excess and umbrella components of this product
line, the Company relies more heavily on the BF method than on the paid and case
incurred development methods.

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



Examples of common risk factors, or perceptions thereof, that could change and,
thus, affect the required general liability reserves (beyond those included in
the general discussion section) include:

General liability risk factors

• Changes in claim handling philosophies

• Changes in policy provisions or court interpretation of such provisions

• New or expanded theories of liability

• Trends in jury awards




•      Changes in the propensity to sue, in general with specificity to
       particular issues

• Changes in the propensity to litigate rather than settle a claim

• Increases in attorney involvement in, or impact on, claims

• Changes in statutes of limitations

• Changes in the underlying court system

• Distortions from losses resulting from large single accounts or single issues




• Changes in tort law


• Shifts in lawsuit mix between federal and state courts




•      Changes in claim adjuster processes or reporting which may cause
       distortions in the data being analyzed

• The potential impact of inflation on loss costs

• Changes in settlement patterns

General liability book of business risk factors • Changes in policy provisions (e.g., deductibles, policy limits, endorsements)

• Changes in underwriting standards

• Product mix (e.g., size of account, industries insured, jurisdiction mix)





Unanticipated changes in risk factors can affect reserves. As an indicator of
the causal effect that a change in one or more risk factors could have on
reserves for general liability (excluding asbestos and environmental), a 1%
increase (decrease) in incremental paid loss development for each future
calendar year could result in a 1.5% increase (decrease) in claims and claim
adjustment expense reserves.

Historically, the one-year change in the reserve estimate for this product line,
excluding estimated asbestos and environmental amounts, over the last nine years
has varied from -8% to 6% (averaging -3%) for the Company, and from -4% to 0%
(averaging -2%) for the industry overall.  The Company's year-to-year changes
are driven by, and are based on, observed events during the year.  The Company
believes that its range of historical outcomes is illustrative of reasonably
possible one-year changes in reserve estimates for this product line.  General
liability reserves (excluding asbestos and environmental) represent
approximately 21% of the Company's total claims and claim adjustment expense
reserves.

The Company's change in reserve estimate for this product line, excluding the
impacts of increases in asbestos and environmental reserves and the extension of
the statute of limitations for childhood sexual molestation claims, was 6% for
2019, -1% for 2018 and -4% for 2017. The 2019 change primarily reflected higher
than expected loss experience in Business Insurance for both primary and excess
coverages for accident years 2013 through 2018, partially offset by better than
expected loss experience for management liability coverages in Bond & Specialty
Insurance for accident years 2013 through 2015. The 2018 change primarily
reflected better than expected loss experience for management liability
coverages in Bond & Specialty Insurance for accident years 2013 through 2015,
partially offset by higher than expected loss experience for both primary and
excess coverages in Business Insurance for accident years 2012 through 2017. The
2017 change primarily reflected better than expected loss experience for both
primary and excess coverages for accident years 2009 through 2016.

Commercial Property
Commercial property is generally considered a short tail line with a simpler and
faster claim reporting and adjustment process than liability coverages, and less
uncertainty in the reserve setting process (except for more complex business
interruption claims). It is generally viewed as a moderate frequency, low to
moderate severity line, except for catastrophes and coverage related to large
properties. The claim reporting and settlement process for property coverage
claim reserves is generally restricted to the insured and the insurer. Overall,
the claim liabilities for this line create a low estimation risk, except
possibly for catastrophes and business interruption claims.

                                      107
--------------------------------------------------------------------------------



Commercial property reserves are typically analyzed in two components, one for
catastrophic or other large single events, and another for all other events.
Examples of common risk factors, or perceptions thereof, that could change and,
thus, affect the required property reserves (beyond those included in the
general discussion section) include:

Commercial property risk factors

• Physical concentration of policyholders

• Availability and cost of local contractors




•      For the more severe catastrophic events, "demand surge" inflation, which
       refers to significant short-term increases in building material and labor

costs due to a sharp increase in demand for those materials and services




• Local building codes


• Amount of time to return property to full usage (for business interruption

claims)

• Frequency of claim re-openings on claims previously closed

• Court interpretation of policy provisions (such as occurrence definition,

or wind versus flooding)

• Lags in reporting claims (e.g., winter damage to summer homes, hidden

damage after an earthquake, hail damage to roofs and/or equipment on

roofs)

• Court or legislative changes to the statute of limitations





Commercial property book of business risk factors
• Policy provisions mix (e.g., deductibles, policy limits, endorsements)


• Changes in underwriting standards

Unanticipated changes in risk factors can affect reserves. As an indicator of the causal effect that a change in one or more risk factors could have on reserves for property, a 1% increase (decrease) in incremental paid loss development for each future calendar year could result in a 1.1% increase (decrease) in claims and claim adjustment expense reserves.



Historically, the one-year change in the reserve estimate for this product line
over the last nine years has varied from -22% to -5% (averaging -13%) for the
Company, and from -14% to -5% (averaging -8%) for the industry overall. The
Company's year-to-year changes are driven by, and are based on, observed events
during the year. The Company believes that its range of historical outcomes is
illustrative of reasonably possible one-year changes in reserve estimates for
this product line. Commercial property reserves represent approximately 2% of
the Company's total claims and claim adjustment expense reserves.

Since commercial property is considered a short tail coverage, the one year
change for commercial property can be more volatile than that for the longer
tail product lines. This is due to the fact that the majority of the reserve for
commercial property relates to the most recent accident year, which is subject
to the most uncertainty for all product lines. This recent accident year
uncertainty is relevant to commercial property because weather-related events
that occur in the second half of the year may not be completely resolved until
the following year. Reserve estimates associated with major catastrophes may
take even longer to resolve. The reserve estimates for this product line are
also potentially subject to material changes due to uncertainty in measuring
ultimate losses for significant catastrophes such as Storm Sandy and wildfires.

The Company's change in reserve estimate for this product line was -6% for 2019,
-11% for 2018 and -9% for 2017. The 2019 change primarily reflected better than
expected loss experience related to both catastrophe and non-catastrophe losses
for accident years 2016 through 2018. The 2018 change primarily reflected better
than expected loss experience related to both catastrophe and non-catastrophe
losses for accident years 2015 through 2017. The 2017 change primarily reflected
better than expected loss experience related to non-catastrophe losses for
accident years 2015 and 2016.

Commercial Multi-Peril
Commercial multi-peril provides a combination of property and liability coverage
typically for small businesses and, therefore, includes both short and long tail
coverages. For property coverage, it generally takes a relatively short period
of time to close claims, while for the other coverages, generally for the
liability coverages, it takes a longer period of time to close claims.

The reserving risk for this line is dominated by the liability coverage portion
of this product, except occasionally in the event of catastrophic or other large
single loss events. The reserving risk for this line differs from that of the
general liability product line and the property product line due to the nature
of the customer. Commercial multi-peril is generally sold to small- to mid-sized
accounts, while the customer profile for general liability and commercial
property includes larger customers.

                                      108
--------------------------------------------------------------------------------

See "Commercial property risk factors" and "General liability risk factors," discussed above, with regard to reserving risk for commercial multi-peril.



Unanticipated changes in risk factors can affect reserves. As an indicator of
the causal effect that a change in one or more risk factors could have on
reserves for commercial multi-peril (excluding asbestos and environmental), a 1%
increase (decrease) in incremental paid loss development for each future
calendar year could result in a 1.2% increase (decrease) in claims and claim
adjustment expense reserves.

Historically, the one-year change in the reserve estimate for this product line,
excluding estimated asbestos and environmental amounts, over the last nine years
has varied from -5% to 5% (averaging 1%) for the Company, and from -4% to 1%
(averaging -2%) for the industry overall. The Company's year-to-year changes are
driven by, and are based on, observed events during the year. The Company
believes that its range of historical outcomes is illustrative of reasonably
possible one-year changes in reserve estimates for this product line. Commercial
multi-peril reserves (excluding asbestos and environmental reserves) represent
approximately 8% of the Company's total claims and claim adjustment expense
reserves.

As discussed above, this line combines general liability and commercial property
coverages and it has been impacted in the past by many of the same events as
those two lines.

The Company's change in reserve estimate for this product line was 4% for 2019,
1% for 2018 and -5% for 2017. The 2019 change primarily reflected higher than
expected loss experience for liability coverages for accident years 2017 and
2018. The 2018 change primarily reflected higher than expected loss experience
for liability coverages for accident year 2017. The 2017 change primarily
reflected better than expected loss experience for liability coverages for
accident years 2016 and prior.

Commercial Automobile
The commercial automobile product line is a mix of property and liability
coverages and, therefore, includes both short and long tail coverages. The
payments that are made quickly typically pertain to auto physical damage
(property) claims and property damage (liability) claims. The payments that take
longer to finalize and are more difficult to estimate relate to bodily injury
claims. In general, claim reporting lags are generally short, claim complexity
is not a major issue, and the line is viewed as high frequency, low to moderate
severity. Overall, the claim liabilities for this line create a moderate
estimation risk. Recently, the Company has seen more of an increase in the rate
of attorney involvement than it had anticipated and a lengthening of the claim
development pattern. As a consequence, the Company has experienced a higher
level of bodily injury severity than it had anticipated.

Commercial automobile reserves are typically analyzed in four components: bodily
injury liability; property damage liability; collision claims; and comprehensive
claims. These last two components have minimum reserve risk and fast payouts
and, accordingly, separate risk factors are not presented.

The Company utilizes the conventional actuarial methods mentioned in the general discussion above in estimating claim liabilities for this line. This is supplemented with detailed custom analyses where needed.



Examples of common risk factors, or perceptions thereof, that could change and,
thus, affect the required commercial automobile reserves (beyond those included
in the general discussion section) include:

Bodily injury and property damage liability risk factors

• Trends in jury awards

• Changes in the underlying court system




• Changes in case law


• Litigation trends

• Increases in attorney involvement in, or impact on, claims

• Frequency of claims with payment capped by policy limits

• Change in average severity of accidents, or proportion of severe accidents

• Changes in auto safety technology

• Subrogation opportunities

• Changes in claim handling philosophies

• Frequency of visits to health providers

• Number of medical procedures given during visits to health providers

• Types of health providers used


                                      109
--------------------------------------------------------------------------------

• Types of medical treatments received

• Changes in cost of medical treatments

• Degree of patient responsiveness to treatment

Commercial automobile book of business risk factors



•      Changes in policy provisions (e.g., deductibles, policy limits,
       endorsements, etc.)


•      Changes in mix of insured vehicles (e.g., long haul trucks versus local
       and smaller vehicles, fleet risks versus non-fleets)

• Changes in underwriting standards





Unanticipated changes in risk factors can affect reserves. As an indicator of
the causal effect that a change in one or more risk factors could have on
reserves for commercial automobile, a 1% increase (decrease) in incremental paid
loss development for each future calendar year could result in a 1.3% increase
(decrease) in claims and claim adjustment expense reserves.

Historically, the one-year change in the reserve estimate for this product line
over the last nine years has varied from -2% to 11% (averaging 4%) for the
Company, and from -3% to 7% (averaging 3%) for the industry overall. The
Company's year-to-year changes are driven by, and are based on, observed events
during the year. The Company believes that its range of historical outcomes is
illustrative of reasonably possible one-year changes in reserve estimates for
this product line. Commercial automobile reserves represent approximately 8% of
the Company's total claims and claim adjustment expense reserves.

The Company's change in reserve estimate for this product line was 7% for 2019,
11% for 2018 and 4% for 2017. The 2019 change primarily reflected higher than
expected loss experience for liability coverages for accident years 2015 through
2018. The 2018 change primarily reflected higher than expected loss experience
for liability coverages for accident years 2014 through 2017. The 2017 change
primarily reflected higher than expected loss experience for liability coverages
for accident years 2013 through 2016.

Workers' Compensation
Workers' compensation is generally considered a long tail coverage, as it takes
a relatively long period of time to finalize claims from a given accident year.
While certain payments such as initial medical treatment or temporary wage
replacement for the injured worker are made quickly, some other payments are
made over the course of several years, such as awards for permanent partial
injuries. In addition, some payments can run as long as the injured worker's
life, such as permanent disability benefits and on-going medical care. Despite
the possibility of long payment tails, the reporting lags are generally short,
payment obligations are generally not complex, and most of the liability can be
considered high frequency with moderate severity. The largest reserve risk
generally comes from the low frequency, high severity claims providing lifetime
coverage for medical expense arising from a worker's injury, as such claims are
subject to greater inflation risk. Overall, the claim liabilities for this line
create a somewhat greater than moderate estimation risk.

Workers' compensation reserves are typically analyzed in three components: indemnity losses, medical losses and claim adjustment expenses.



Examples of common risk factors, or perceptions thereof, that could change and,
thus, affect the required workers' compensation reserves (beyond those included
in the general discussion section) include:

Indemnity risk factors
• Time required to recover from the injury


• Degree of available transitional jobs

• Degree of legal involvement

• Changes in the interpretations and processes of the administrative bodies

that oversee workers' compensation claims

• Future wage inflation for states that index benefits

• Changes in the administrative policies of second injury funds

Medical risk factors • Changes in the cost of medical treatments (including prescription drugs)

and underlying fee schedules ("inflation")

• Frequency of visits to health providers

• Number of medical procedures given during visits to health providers

• Types of health providers used

• Type of medical treatments received

• Use of preferred provider networks and other medical cost containment


       practices



                                      110

• Availability of new medical processes and equipment




•      Changes in the use of pharmaceutical drugs, including drugs for pain
       management

• Degree of patient responsiveness to treatment

• Frequency of reopening claims previously closed


• Mortality trends of injured workers with lifetime benefits and medical

treatment

• Changes in statutory benefits

• The impact, if any, of potential future changes to government health

insurance legislation

Unanticipated changes in risk factors can affect reserves. As an indicator of
the causal effect that a change in one or more risk factors could have on
reserves for workers' compensation, a 1% increase (decrease) in incremental paid
loss development for each future calendar year could result in a 1.3% increase
(decrease) in claims and claim adjustment expense reserves.

Historically, the one-year change in the reserve estimate for this product line
over the last nine years has varied from -4% to 0% (averaging -2%) for the
Company, and from -4% to 1% (averaging -2%) for the industry overall. The
Company's year-to-year changes are driven by, and are based on, observed events
during the year. The Company believes that its range of historical outcomes is
illustrative of reasonably possible one-year changes in reserve estimates for
this product line. Workers' compensation reserves represent approximately 38% of
the Company's total claims and claim adjustment expense reserves.

The Company's change in reserve estimate for this product line was -4% for 2019,
-4% for 2018 and -3% for 2017. The 2019 change primarily reflected better than
expected loss experience for accident years 2018 and prior. The 2018 change
primarily reflected better than expected loss experience for accident years 2017
and prior. The 2017 change primarily reflected better than expected loss
experience for accident years 2016 and prior.

Fidelity and Surety
Fidelity is generally considered a short tail coverage. It takes a relatively
short period of time to finalize and settle most fidelity claims. The volatility
of fidelity reserves is generally related to the type of business of the
insured, the size and complexity of the insured's business operations, amount of
policy limit and attachment point of coverage. The uncertainty surrounding
reserves for small, commercial insureds is typically less than the uncertainty
for large commercial or financial institutions. The high frequency, low severity
nature of small commercial fidelity losses provides for stability in loss
estimates, whereas the low frequency, high severity nature of losses for large
insureds results in a wider range of ultimate loss outcomes. Actuarial
techniques that rely on a stable pattern of loss development are generally not
applicable to low frequency, high severity claims.

Surety has certain components that are generally considered short tail coverages
with short reporting lags, although large individual construction and commercial
surety contracts can result in a long settlement tail, based on the length and
complexity of the construction project(s) or commercial transaction being
bonded. The frequency of losses in surety generally correlates with economic
cycles as the primary cause of surety loss is the inability of an insured to
fulfill its contractual obligations. The Company actively seeks to mitigate this
exposure to loss through disciplined risk selection, adherence to underwriting
standards and ongoing monitoring of contractor progress in significant
construction projects. The volatility of surety losses is generally related to
the type of business performed by the bonded party, the type of bonded
obligation, the amount of limit exposed to loss and the amount of assets
available to the surety company to mitigate losses, such as unbilled contract
funds, collateral, first and third party indemnity, and other security positions
of a bonded party's assets. Certain classes of surety claims are very high
severity, low frequency in nature. These can include large construction
contractors involved with one or multiple large, complex projects as well as
certain large commercial surety exposures. Other claim factors affecting reserve
variability of surety include litigation related to amounts owed by the bonded
party and due to the surety company (e.g., salvage and subrogation efforts), the
results of financial restructuring of a bonded party and the availability and
cost of replacement contractors, labor and materials.

Examples of common risk factors, or perceptions thereof, that could change and,
thus, affect the required fidelity and surety reserves (beyond those included in
the general discussion section) include:

Unanticipated changes in risk factors can affect reserves. As an indicator of
the causal effect that a change in one or more risk factors could have on
reserves for fidelity and surety, a 1% increase (decrease) in incremental paid
loss development for each future calendar year could result in a 1.2% increase
(decrease) in claims and claim adjustment expense reserves.

Historically, the one-year change in the reserve estimate for this product line
over the last nine years has varied from -36% to -8% (averaging -19%) for the
Company, and from -17% to -6% (averaging -11%) for the industry overall.  The
Company's year-to-year changes are driven by, and are based on, observed events
during the year.  The Company believes that its range of historical outcomes is
illustrative of reasonably possible one-year changes in reserve estimates for
this product line.  Fidelity and surety reserves represent approximately 1% of
the Company's total claims and claim adjustment expense reserves.

In general, developments on single large claims (both adverse and favorable) are a primary source of changes in reserve estimates for this product line.



The Company's change in reserve estimate for this product line was -11% for
2019, -10% for 2018 and -10% for 2017. The 2019 change primarily reflected
better than expected loss experience in the fidelity and surety product line for
accident year 2017. The 2018 change primarily reflected better than expected
loss experience in the fidelity and surety product line for accident years 2015
and 2016. The 2017 change primarily reflected better than expected loss
experience in the fidelity and surety product line for accident years 2014 and
2015.

Personal Automobile
Personal automobile includes both short and long tail coverages. The payments
that are made quickly typically pertain to auto physical damage (property)
claims and property damage (liability) claims. The payments that take longer to
finalize and are more difficult to estimate relate to bodily injury claims.
Reporting lags are relatively short and the claim settlement process for
personal automobile liability generally is the least complex of the liability
products. It is generally viewed as a high frequency, low to moderate severity
product line. Overall, the claim liabilities for this line create a moderate
estimation risk.

Personal automobile reserves are typically analyzed in five components: bodily
injury liability, property damage liability, no-fault losses, collision claims
and comprehensive claims. These last two components have minimum reserve risk
and fast payouts and, accordingly, separate factors are not presented.

Examples of common risk factors, or perceptions thereof, that could change and,
thus, affect the required personal automobile reserves (beyond those included in
the general reserve discussion section) include:

Unanticipated changes in risk factors can affect reserves. As an indicator of
the causal effect that a change in one or more risk factors could have on
reserves for personal automobile, a 1% increase (decrease) in incremental paid
loss development for each future calendar year could result in a 1.1% increase
(decrease) in claims and claim adjustment expense reserves.

Historically, the one-year change in the reserve estimate for this product line
over the last nine years has varied from -4% to 3% (averaging 0%) for the
Company, and from -3% to 2% (averaging -1%) for the industry overall. The
Company's year-to-year changes are driven by, and are based on, observed events
during the year. The Company believes that its range of historical outcomes is
illustrative of reasonably possible one-year changes in reserve estimates for
this product line. Personal automobile reserves represent approximately 7% of
the Company's total claims and claim adjustment expense reserves.

The Company's change in reserve estimate for this product line was -2% for 2019,
-2% for 2018 and 0% for 2017. The 2019 change primarily reflected better than
expected loss experience for liability coverages in accident years 2016 through
2018. The 2018 change primarily reflected better than expected loss experience
for liability coverages for accident years 2015 through 2017.

Homeowners and Personal Lines Other
Homeowners is generally considered a short tail coverage. Most payments are
related to the property portion of the policy, where the claim reporting and
settlement process is generally restricted to the insured and the insurer.
Claims on property coverage are typically reported soon after the actual damage
occurs, although delays of several months are not unusual. The resulting
settlement process is typically fairly short term, although exceptions do exist.

The liability portion of the homeowners policy generates claims which take
longer to pay due to the involvement of litigation and negotiation, but with
generally small reporting lags. Personal Lines Other products include personal
umbrella policies, among others. See "general liability reserving risk factors,"
discussed above, for reserving risk factors related to umbrella coverages.

Overall, the line is generally high frequency, low to moderate severity (except for catastrophes), with simple to moderate claim complexity.

Homeowners reserves are typically analyzed in two components: non-catastrophe related losses and catastrophe loss payments.

Examples of common risk factors, or perceptions thereof, that could change and, thus, affect the required homeowners reserves (beyond those included in the general discussion section) include:



Non-catastrophe risk factors
• Salvage opportunities


• Amount of time to return property to residential use

• Changes in weather patterns


                                      113
--------------------------------------------------------------------------------

• Local building codes

• Construction and building material costs




• Litigation trends


• Trends in jury awards

• Court interpretation of policy provisions (such as occurrence definition,

or wind versus flooding)

• Lags in reporting claims (e.g., winter damage to summer homes, hidden

damage after an earthquake, hail damage to roofs and/or equipment on

roofs)

• Court or legislative changes to the statute of limitations





Catastrophe risk factors
• Physical concentration of policyholders


• Availability and cost of local contractors

• Local building codes

• Quality of construction of damaged homes

• Amount of time to return property to residential use




•      For the more severe catastrophic events, "demand surge" inflation, which
       refers to significant short-term increases in building material and labor

costs due to a sharp increase in demand for those materials and services

Homeowners book of business risk factors • Policy provisions mix (e.g., deductibles, policy limits, endorsements, etc.)

• Degree of concentration of policyholders

• Changes in underwriting standards

• Changes in the use of permissible data for rating and underwriting





Unanticipated changes in risk factors can affect reserves. As an indicator of
the causal effect that a change in one or more risk factors could have on
reserves for homeowners and personal lines other, a 1% increase (decrease) in
incremental paid loss development for each future calendar year could result in
a 1.1% increase (decrease) in claims and claim adjustment expense reserves.

Historically, the one-year change in the reserve estimate for this product line
(excluding the umbrella line of business, which for statutory reporting purposes
is included with the general liability line of business) over the last nine
years has varied from -17% to 3% (averaging -8%) for the Company, and from -7%
to 1% (averaging -4%) for the industry overall. The Company's year-to-year
changes are driven by, and are based on, observed events during the year. The
Company believes that its range of historical outcomes is illustrative of
reasonably possible one-year changes in reserve estimates for this product line.
Homeowners and personal lines other reserves represent approximately 3% of the
Company's total claims and claim adjustment expense reserves.

This line combines both liability and property coverages; however, the majority
of the reserves relate to property. While property is considered a short tail
coverage, the one year change for property can be more volatile than that for
the longer tail product lines. This is due to the fact that the majority of the
reserve for property relates to the most recent accident year, which is subject
to the most uncertainty for all product lines. This recent accident year
uncertainty is relevant to property because of weather related events which tend
to be concentrated in the second half of the year, and generally are not
completely resolved until the following year. Reserve estimates associated with
major catastrophes, including California wildfires in recent years, may take
even longer to resolve.

The Company's change in reserve estimate for this product line (excluding the
umbrella line of business) was -3% for 2019, -2% for 2018 and 1% for 2017. The
2019 change primarily reflected better than expected loss experience for
catastrophe and non-catastrophe losses for accident years 2015, 2016 and 2018.
The 2018 change primarily reflected better than expected loss experience for
liability coverages for accident years 2014 through 2016, largely offset by
higher than expected loss experience for catastrophe losses for accident year
2017. The 2017 change primarily reflected modestly higher than expected loss
experience for liability coverages for accident years 2014 and 2015.

International and Other
International and other includes products written by the Company's international
operations, as well as all other products not explicitly discussed above. The
principal component of "other" claim reserves is assumed reinsurance written on
an excess-of-loss basis, which may include reinsurance of non-U.S. exposures,
and is runoff business.


                                      114

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


International and other claim liabilities result from a mix of coverages,
currencies and jurisdictions/countries. The common characteristic is the need to
customize the analysis to the individual component, and the inability to rely on
data characterizations and reporting requirements in the U.S. statutory
reporting framework.

Due to changes in the business mix for this product line over time, incurred
claim liabilities for more recent years are generally shorter-tailed (due to
both the products and the jurisdictions involved, e.g., Canada, the Republic of
Ireland and the United Kingdom), compared to the older liabilities from runoff
operations that are extremely long tail (e.g., U.S. excess liabilities reinsured
through the London market, and several underwriting pools in runoff). The speed
of claim reporting and claim settlement is a function of the specific coverage
provided, the jurisdiction, the distribution system (e.g., underwriting pool
versus direct) and the proximity of the insurance sale to the insured hazard
(e.g., insured and insurer located in different countries). In particular,
liabilities arising from the underwriting pools in runoff may result in
significant reporting lags, settlement lags and claim complexity, due to the
need to coordinate with other pool members or co-insurers through a broker or
lead-insurer for claim settlement purposes.

International reserves are generally analyzed by country and general coverage
category (e.g., General Liability in Canada, Commercial Property in the United
Kingdom, etc.). The business is also generally split by direct versus assumed
reinsurance for a given coverage. Where the underlying insured hazard is outside
the United States, the underlying coverages are generally similar to those
described under the Homeowners, Personal Automobile, Commercial Automobile,
General Liability, Commercial Property and Surety discussions above, taking into
account differences in the legal environment and differences in terms and
conditions. However, statutory coverage differences exist amongst various
jurisdictions. For example, in some jurisdictions there are no aggregate policy
limits on certain liability coverages.

Other reserves, primarily assumed reinsurance in runoff, are generally analyzed
by program/pool, treaty type, and general coverage category (e.g., General
Liability - excess of loss reinsurance). Excess exposure requires the insured to
"prove" not only claims under the policy, but also the prior payment of claims
reaching up to the excess policy's attachment point.

Examples of common risk factors, or perceptions thereof, that could change and,
thus, affect the required International and other reserves (beyond those
included in the general discussion section, and in the Personal Automobile,
Homeowners, General Liability, Commercial Property, Commercial Automobile and
Surety discussions above) include:

International and other risk factors • Changes in claim handling procedures, including those of the primary carriers

• Changes in policy provisions or court interpretation of such provision

• Economic trends

• New theories of liability

• Trends in jury awards

• Changes in the propensity to sue

• Changes in statutes of limitations

• Changes in the underlying court system

• Distortions from losses resulting from large single accounts or single issues




• Changes in tort law


• Changes in claim adjuster office structure (causing distortions in the data)

• Changes in foreign currency exchange rates

International and other book of business risk factors • Changes in policy provisions (e.g., deductibles, policy limits,

endorsements, "claims-made" language)

• Changes in underwriting standards

• Product mix (e.g., size of account, industries insured, jurisdiction mix)





Unanticipated changes in risk factors can affect reserves. As an indicator of
the causal effect that a change in one or more risk factors could have on
reserves for International and other (excluding asbestos and environmental), a
1% increase (decrease) in incremental paid loss development for each future
calendar year could result in a 1.3% increase (decrease) in claims and claim
adjustment expense reserves. International and other reserves (excluding
asbestos and environmental) represent approximately 8% of the Company's total
claims and claim adjustment expense reserves.

International and other represents a combination of different product lines,
some of which are in runoff. Comparative historical information is not available
for international product lines as insurers domiciled outside of the United
States do not file U.S. statutory reports. Comparative historical information on
runoff business is not indicative of reasonably possible one-year changes

                                      115
--------------------------------------------------------------------------------

in the reserve estimate for this mix of runoff business. Accordingly, the Company has not included comparative analyses for International and other.



Reinsurance Recoverables
Amounts recoverable from reinsurers are estimated in a manner consistent with
the associated claim liability. The Company evaluates and monitors the financial
condition of its reinsurers under voluntary reinsurance arrangements to minimize
its exposure to significant losses from reinsurer insolvencies. In addition, in
the ordinary course of business, the Company becomes involved in coverage
disputes with its reinsurers. Some of these disputes could result in lawsuits
and arbitrations brought by or against the reinsurers to determine the Company's
rights and obligations under the various reinsurance agreements. The Company
employs dedicated specialists and comprehensive strategies to manage reinsurance
collections and disputes.

The Company has entered into a reinsurance contract in connection with
catastrophe bonds issued by Long Point Re III. This contract meets the
requirements to be accounted for as reinsurance in accordance with guidance for
accounting for reinsurance contracts. The catastrophe bonds are described in
more detail in "Item 1-Business-Catastrophe Reinsurance."

The Company reports its reinsurance recoverables net of an allowance for
estimated uncollectible reinsurance recoverables. The allowance is based upon
the Company's ongoing review of amounts outstanding, length of collection
periods, changes in reinsurer credit standing, disputes, applicable coverage
defenses and other relevant factors. Accordingly, the establishment of
reinsurance recoverables and the related allowance for uncollectible reinsurance
recoverables is also an inherently uncertain process involving estimates. From
time to time, as a result of the long-tailed nature of the underlying
liabilities, coverage complexities and potential for disputes, the Company
considers the commutation of reinsurance contracts. Changes in estimated
reinsurance recoverables and commutation activity could result in additional
income statement charges.

Recoverables attributable to structured settlements relate primarily to personal
injury claims, of which workers' compensation claims comprise a significant
portion, for which the Company has purchased annuities and remains contingently
liable in the event of a default by the companies issuing the annuities.
Recoverables attributable to mandatory pools and associations relate primarily
to workers' compensation service business. These recoverables are supported by
the participating insurance companies' obligation to pay a pro rata share based
on each company's voluntary market share of written premium in each state in
which it is a pool participant. In the event a member of a mandatory pool or
association defaults on its share of the pool's or association's obligations,
the other members' share of such obligation increases proportionally.

Investment Valuation and Impairments
Valuation of Investments Reported at Fair Value in Financial Statements
The Company's estimates of fair value for financial assets and financial
liabilities are based on the framework established in the fair value accounting
guidance. The framework is based on the inputs used in valuation, gives the
highest priority to quoted prices in active markets and requires that observable
inputs be used in the valuations when available.

The fair value of a financial instrument is the estimated amount at which the
instrument could be exchanged in an orderly transaction between knowledgeable,
unrelated, willing parties, i.e., not in a forced transaction. The estimated
fair value of a financial instrument may differ from the amount that could be
realized if the security was sold in an immediate sale, e.g., a forced
transaction. Additionally, the valuation of investments is more subjective when
markets are less liquid due to the lack of market based inputs, 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.

See note 4 of notes to the consolidated financial statements for a further discussion of the determination of fair value of investments.



Investment Impairments
See note 1 of notes to the consolidated financial statements for a discussion of
investment impairments.

Due to the subjective nature of the Company's analysis and estimates of future
cash flows, along with the judgment that must be applied in the analysis, it is
possible that the Company could reach a different conclusion whether or not to
impair a security if it had access to additional information about the issuer.
Additionally, it is possible that the issuer's actual ability to meet
contractual obligations may be different than what the Company determined during
its analysis, which may lead to a different impairment conclusion in future
periods.
