RECORD UNDERWRITING INCOME

RECORD NET INVESTMENT INCOME

2023 was an extraordinarily 
positive year for our Company. 
We had record profitability and 
revenue. Both underwriting 
profit and investment income 
achieved new all-time highs of 
$1.1 billion each, and our cash 
flow for the year exceeded $2.9 
billion. This is the second year in 
a row our return on shareholders’ 
equity exceeded 20%. We were 
able to pay special dividends 
to our shareholders as a direct 
result of these outstanding 
returns. Book value per share, 
before dividends and stock 
buybacks, grew in excess of 
25%. Our goal, as always, is to 
optimize our risk-adjusted return 
to our shareholders. We achieved 
that in 2023.

While our primary goal is focused 
on return to our shareholders, our 
business is built on a concern for 
the needs of multiple constituents—
society, our customers, our agents 
and brokers and, of course, our 
employees. Our success comes 
from this focus on meeting the 
needs of all of these groups. First 
and foremost, we must meet the 
needs of our customers who buy 
insurance from our companies 
because they are confident that 
we will meet our commitments 
in the appropriate way. Agents 
and brokers feel confident 
recommending our businesses 
to their customers because they 
recognize our willingness and 
ability to pay claims as set forth  
in our policies.

RECORD NET INCOME

The role of insurance is extremely 
important in a society that 
seeks to manage the impact 
of unforeseen events. Our 
Company’s financial strength 
and stability, as well as our 
historical reputation of meeting 
our obligations, provides peace of 
mind to our customers. We are in 
the insurance market every day. 
Sometimes people choose to buy 
from us and on other occasions, 
they shop elsewhere, but we are 
always in the marketplace. We 
are a dependable partner offering 
coverage on a consistent basis. 
This long-term view of being 
consistently in the market ties 
in with the key differential that 
has helped make W. R. Berkley 
Corporation stand out from many 
of its competitors. 

We have a long-term view while 
acknowledging the present risks, but 
our focus is always on long-term 
risk-adjusted return. Commitments 
made by our Company often extend 

for years. Thus, the time element is 
critical when focusing on risk. We 
are concerned about tomorrow, next 
month and next quarter, as well 
as minimizing extreme volatility. 
Our primary focus, however, is 
the general direction and long-
term outcome of society’s values, 
economic trends, and the impact 
and long-term consequences of our 
decision-making from a financial 
point of view. 

Whether it is our decision to 
start businesses or to take on 
the uncertainty inherent in 
acquisitions, we continue to be 
concerned about the influence of 
long-term social and economic 
issues, such as inflation. When 
establishing the guidelines for our 
investment portfolio, that long-
term view is critical. The ability 
to manage our enterprise in an 
effective way, and still deliver 
outstanding risk-adjusted returns 
to our shareholders comes from 
this long-term perspective.

W. R. Berkley Corporation 2023 Annual Report     9To our  
shareholders

This year, our premiums grew 
by over 9.5%. We continued 
to build our business through 
internal growth and the addition 
of one new business. Many of 
the businesses that were started 
during the past several years 
began to come into their own, 
while at the same time, other 
areas of our business required 
us to take our foot off the 
accelerator because pricing was 
not as attractive as it had been.  

Today, varying lines of business 
react in different ways in 
the marketplace. This is the 
advantage of our structure. By 
having 60 individual businesses, 
we can independently respond to 
each competitive circumstance.

these benefits exceed the cost 
of our structure. We continue to 
evaluate each of our businesses, 
how we compete, and where we 
compete, to ensure that we get 
value for the scale and size of each 
piece of our business. 

Each of our companies operates 
on its own in its marketplace. We 
have the benefits of a large-scale 
enterprise while still maintaining 
the flexibility of being nimble 
that generally exists only in much 
smaller companies. It is this 
combination that allows us to 
be a more flexible and effective 
competitor. In this ever-more-
rapidly changing world, we think 

As we continue to build our 
enterprise, we find the Berkley 
name has benefited many of our 
new companies, continuing to 
add strength when we start a new 
venture. We now have a number of 
companies that individually have 
achieved scale in their particular 
market niche. This makes them 
truly viable competitors against 
almost any of the global markets.

WE HOPE TO 

CONTINUE 

BUILDING OUR  

BUSINESS IN THE 

SAME MANNER 

THAT WE HAVE  

BUILT IT IN THE 

PAST, ONE BLOCK 

AT A TIME.

We hope to continue building 
our business in the same manner 
that we have built it in the past, 
one block at a time.

Our structure is especially 
valuable when considered 
in light of our long-term 
perspective. It allows us to attract 
entrepreneurial talent to build 
new businesses. When they enter 
the market, they can demonstrate 
a strength and stability that only 
their largest competitors possess. 
This helps us continue to build 
our business, and we believe it 
will allow us to grow consistently 
and faster than most of our 
competitors.

Taken all together, this has 
resulted in an outstanding year 
for our Company. This was a year 
everyone on our team was proud 
of. We want to thank all of our 
brokers and agents who produced 
policies for our companies. 

Thank you, as well, to each and 
every member of our team, our 
shareholders, and our customers. 
Without you, we could not 
have achieved this outstanding 
year. It required everyone, both 
individually and collectively, for 
us to achieve this result. It goes 
without saying that the advice 
and counsel provided by our 
Board of Directors has helped us 
immeasurably, and we continue to 
be optimistic as we look ahead.

BERKLEY’S SPECIALTY INSURANCE  
BUSINESSES PROVIDE THE PEACE OF MIND AND 
RESILIENCE NECESSARY FOR INDIVIDUALS  
AND BUSINESSES TO SUCCEED AND THRIVE.

Insurance is the business of 
protecting against losses resulting 
from various types of events, which 
enables individuals and businesses 
to endure their biggest crises and 
return to their lives. It provides 
people with the peace of mind to go 
about their daily activities without 
worrying about the financial 
consequences of unforeseen events.

Insurance offers predictability in 
the face of life’s many uncertainties 
and provides stability for society 
to function. Groups of insureds 
spread their exposure to similar 
risks by paying relatively small 
periodic premium payments for 
insurance coverage, rather than 
paying for a large loss all at once. 
Then, when the unthinkable 
happens, timely claims payments 
can help families, communities 
and businesses recover from 
costly accidents and disasters and 
continue on as they did before the 
event occurred. It helps to make 
them whole.

We help protect business properties, 
homes, and other physical assets, 
as well as reputations, earnings 
streams, and the ability to operate 
in the same way as before a loss 
occurred. We also help people 
and businesses prevent losses or 

reduce exposure before an event 
occurs through loss control and 
education activities that help aid in 
understanding and managing the 
various exposures they face. The 
specialized expertise we bring to 
bear through our 60 autonomous 
businesses allows us to understand 
our policyholders’ activities and 
the risks they face, provide tailored 
insurance coverages and handle 
claims with expertise.  

The benefits we provide are more 
than just fulfilling the contractual 
obligations of our policies. We 
understand the financial, intangible, 
and sentimental value of what we 
protect, never losing sight of the 
fact that we are entrusted with the 
hopes, dreams, and often life’s work 
of people. For example, our excess 
workers’ compensation business 
is experienced at handling claims 
related to catastrophic injuries 
in the workplace. In managing 
claims, we aim to provide the 
injured worker with the highest 
quality outcome, focused not just 
on medical care and rehabilitation, 
but also on maximizing recovery, 
quality of life, and independence. 
Our liability coverages provide 
payment for various types of 
damages, injuries, and errors 
or omissions for many types of

 Investments

Investments 
for growth & progress

 An insurance company invests money with the expectation of  

achieving a return or increasing value, often putting it into assets that help 

build the economy and allow enterprises of all types to move forward.

INVESTING IN BUSINESSES AND INFRASTRUCTURE 
PROVIDES A DUAL BENEFIT OF CONTRIBUTING  
TO OUR LONG-TERM RISK-ADJUSTED RETURN WHILE 
ENABLING THE ECONOMY TO EXPAND  
AND FLOURISH.

Investment income is a key 
component of an insurance 
company’s economic model, 
placing our industry at the heart  
of the growth and progress of 
every modern economy. We invest 
with a view towards risk-adjusted 
return, which means we must 
understand the levels of risk in 
each investment so we can meet 
our obligations to our insureds 
and provide a strong return to our 
shareholders.

We primarily invest in fixed-
maturity securities, as well as 
other opportunities that help 
society work more effectively. 
The recipients of our capital 
are typically corporations, 

municipalities, and federal 
governments. Government 
bonds support the development 
of infrastructure and federal 
programs, while municipal bonds 
lower borrowing costs for state 
and local governments, allowing 
for greater investments in those 
municipalities and reducing 
tax rates for residents. Some 
municipal bonds may fund 
projects regarding water and 
sewer, waste, pollution, industrial 
development, and resource 
recovery, which can help mitigate 
pollution, provide safe drinking 
water, and promote conservation. 
Mortgage and other asset-
backed bonds allow consumers 
to buy homes and other things,

Investment Income

while corporate bonds allow 
businesses to expand and 
thrive, bolstering job creation 
and economic growth. Housing 
bonds provide funding for 
multifamily or single-family 
housing projects, often for 
the low-income sector, while 
transportation bonds support 
our country’s infrastructure by 
improving toll roads, bridges, 
and tunnels. Additionally, our 
investments in secondary 
and higher education support 
enterprises directly involved in 
improving communities and the 
lives of their students. 

Through our investments, we 
make important contributions 
to the safety and security of 
our society, the stability of 
our financial systems, and the 
development of infrastructure. 
In this sense, our investments 
help to stimulate the economy’s 
savings and investments, 
allowing businesses and 
consumers to have a higher level 
of consumption and plan more 
confidently. Our investments 
help to build the economy and 
allow society to move forward.

Growth

Growth 
to meet obligations

 A well-run insurance company increases capital over  

time through profits arising from sound business decisions 

that support a multitude of constituents.

THE EXPANSION OF CAPITAL OVER THE  
LONG-TERM ENABLES US TO CONSISTENTLY  
MEET THE EVOLVING NEEDS OF OUR  
CUSTOMERS AND SOCIETY. 

For insurance to continue to 
fulfill the needs of its constituents, 
primarily its insureds and its 
role in investing in our society, 
insurance companies need to 
produce profits and build capital. 
Underwriting and investing are 
the two engines that drive our 
business, and we manage both 
through the lens of optimizing 
risk-adjusted return on capital to 
live up to the expectations of our 
communities. 

Shareholders provide us with 
the capital to run our business. 
Profits enable us to earn a 
strong risk-adjusted return on 
that capital for shareholders. 
They also enable us to reinvest 
funds back into the organization 
and grow our business to 
meet the evolving needs of 
our policyholders, distribution 
partners, and employees. With 
strong profits, we can deliver 
new products and services that 
address emerging exposures 
in an ever-changing economy, 
expand our resources, develop 
our people, and take calculated 

risks to meet the needs of 
current policyholders and reach 
new policyholders in need of 
support. 

In underwriting, profit 
margins are generally thin – 
approximately 90% of premium is 
used to pay for distribution and 
provide our services, including 
underwriting, loss control, 
education, and claims payments. 
Investment income makes 
an important contribution to 
profitability and, together, they 
provide a solid foundation for 
our business to succeed and all 
of our other interested parties to 
thrive. Today, we service nearly 
1.3 million policies per year.

Albert Einstein famously 
quipped that the eighth wonder 
of the world is the power of 
compounding. Over the past 50 
years as a public company, W. R. 
Berkley Corporation has grown 
net premiums written 24,000% 
and stockholders’ equity by more 
than 66,100%. In addition, we 
have returned over $7.3 billion to 

shareholders through dividends 
and share repurchases. Over that 
time, we have delivered nearly 
18% compound average growth 
in total shareholder return and a 
14.7% average return on equity.

Insurance is a unique business

By being there for our clients, 
we provide the peace of mind

Managing risk is inherent to 
our business, and we do so 

with an unwavering focus on

in our underwriting and our 
investing. We are in the insurance 
market every day with products 
and services that address the 
new and existing exposures 
of an evolving economy and

the economy expand and thrive. 
In the end, it allows us to serve 
humanity in a way few, if any,  
other industries can.

Over the past few years, we have held the duration of our fixed-maturity portfolio at approximately 2.4 years, 
while maintaining its high quality with an average rating of AA-. As a result, there has been less volatility in our 
book value from mark-to-market accounting and we are better able to manage the interest rate environment.

We manage our portfolio for total return, including capital gains. As investment income is an important 
component of our economic model, we will continue to seek out investment opportunities with above average 
risk-adjusted returns and to position our fixed-maturity portfolio to manage the yield curve as well as the 
impact of inflation.

PART I
ITEM  1.  BUSINESS

W. R. Berkley Corporation is an insurance holding company that is among the largest commercial lines writers in the 

United States and operates worldwide in two segments of the property casualty insurance business:

•

•

Insurance - Our Insurance businesses underwrite predominantly commercial insurance business, including excess and 
surplus lines, admitted lines and specialty personal lines throughout the United States, as well as insurance business in 
Asia, Australia, Canada, Continental Europe, Mexico, Scandinavia, South America and the United Kingdom.

Reinsurance & Monoline Excess - Our Reinsurance businesses provide facultative and treaty reinsurance in the United 
States, as well as in the Asia Pacific region, Australia, Continental Europe, South Africa and the United Kingdom. 
Monoline Excess businesses retain risk solely on an excess basis. 

Our two reporting segments are each composed of individual businesses that serve a market defined by geography, 

products, services or industry served. Each of our businesses is positioned close to its customer base and participates in a niche 
market requiring specialized knowledge. This strategy of decentralized operations allows each of our businesses to identify and 
respond quickly and effectively to changing market conditions and specific customer needs, while capitalizing on the benefits 
of centralized capital, investment and reinsurance management, and corporate actuarial, financial, enterprise risk management 
and legal staff support. 

Our business approach is focused on meeting the needs of our customers, maintaining a high quality balance sheet, and 

allocating capital to our best opportunities. New businesses are started when opportunities are identified and when the right 
talent and expertise are found to lead a business. Of our 60 businesses, 53 have been organized and developed internally and 
seven have been added through acquisition. 

Net premiums written, as reported based on United States generally accepted accounting principles (“GAAP”), for 

each of our reporting segments for each of the past three years were as follows:

Thirty-two of our insurance company subsidiaries are rated by A.M. Best Company, Inc. ("A.M. Best") and have 
financial strength ratings of A+ (Superior) (the second highest rating out of 15 possible ratings). A.M. Best's ratings are based 
upon factors of concern to policyholders, insurance agents and brokers and are not directed toward the protection of investors. 
A.M. Best states: “A Best's Financial Strength Rating (FSR) is an independent opinion of an insurer's financial strength and 
ability to meet its ongoing insurance policy and contract obligations. An FSR is not assigned to specific insurance policies or 
contracts and does not address any other risk.” A.M. Best reviews its ratings on a periodic basis, and its ratings of the 
Company's subsidiaries are therefore subject to change.

Our twenty-three insurance company subsidiaries rated by Standard & Poor's (“S&P”) have financial strength ratings of 

A+ (the fifth highest rating out of twenty-seven possible ratings).

Our Moody's financial strength ratings are A1 for Berkley Insurance Company, Berkley Regional Insurance Company 

and Admiral Insurance Company (the fifth highest rating out of twenty-one possible ratings).

Our twenty-five insurance company subsidiaries rated by Fitch Ratings ("Fitch") have insurer financial strength ratings 

of AA- (the fourth highest rating out of twenty-seven possible ratings).

Insurance

Our Insurance businesses underwrite predominantly commercial and specialty personal lines insurance business 
primarily throughout the United States. Many units offer coverage globally, while others specialize in specific international 
markets. The Insurance businesses focus on the following general areas:

Excess & Surplus Lines: A number of our businesses are dedicated to the U.S. excess and surplus lines market. They 

serve a diverse group of customers that often have complex risk or unique exposures that typically fall outside the underwriting 
guidelines of the standard insurance market. Lines of business underwritten by our excess and surplus lines businesses include 
premises operations, auto, property, products liability, general liability and professional liability lines. Products are generally 
distributed through wholesale agents and brokers.

Industry Specialty: Certain other businesses focus on providing specialty coverages to customers within a particular 

industry that are best served by underwriters and claims professionals with specialized knowledge of that industry. They offer 
multiple lines of business with policies tailored to address the unique exposures of these industries, often with the flexibility of 
providing coverages on either an admitted or a non-admitted basis in the U.S., as well as internationally. Each business delivers 
its products through one or more distribution channels, including retail and wholesale agents, brokers, and managing general 
agents (MGAs), depending on the customer and the particular risks insured. 

Product Specialty: Other businesses specialize in providing specific lines of insurance coverage, such as workers’ 

compensation or professional liability, to a wide range of customers. They offer insurance products, analytical tools and risk 
management services such as loss control and claims management that enable clients to manage their risk appropriately. 
Business is typically written on an admitted basis, although some businesses may offer non-admitted products in the U.S. and 
offer products internationally. Independent agents and brokers are the primary means of distribution.

Regional: Certain businesses offer standard insurance products and services focused on meeting the specific needs of a 

geographically differentiated customer base. Key clients are small-to-midsized businesses. These regionally focused businesses 
provide a broad array of commercial insurance products to customers primarily in 45 states and the District of Columbia and 
have developed expertise in niches that reflect local economies. They are organized geographically in order to provide them 
with the flexibility to adapt quickly to local market conditions and customer needs.

products and services to be tailored to each regional customer base. Our businesses are managed by teams of professionals with

Loss and Loss Expense Reserves

To recognize liabilities for unpaid losses, either known or unknown, insurers establish reserves, which is a balance 

sheet account representing estimates of future amounts needed to pay claims and related expenses with respect to insured events 
which have occurred. Estimates and assumptions relating to reserves for losses and loss expenses are based on complex and 
subjective judgments, often including the interplay of specific uncertainties with related accounting and actuarial 
measurements. Such estimates are also susceptible to change as significant periods of time may elapse between the occurrence 
of an insured loss, the report of the loss to the insurer, the ultimate determination of the cost of the loss and the insurer’s 
payment of that loss.

In general, when a claim is reported, claims personnel establish a “case reserve” for the estimated amount of the 

ultimate payment based upon known information about the claim at that time. The estimate represents an informed judgment 
based on general reserving practices and reflects the experience and knowledge of the claims personnel regarding the nature and 
value of the specific type of claim. Reserves are also established on an aggregate basis to provide for losses incurred but not 
reported (“IBNR”) to the insurer, potential inadequacy of case reserves and the estimated expenses of settling claims, including 
legal and other fees and general expenses of administrating the claims adjustment process. Reserves are established based upon 
the then current legal interpretation of coverage provided.

In examining reserve adequacy, several factors are considered in estimating the ultimate economic value of losses. 

These factors include, among others, historical data, legal developments, changes in social attitudes and economic conditions, 
including the effects of inflation. The actuarial process relies on the basic assumption that past experience, adjusted 
judgmentally for the effects of current developments and anticipated trends, is an appropriate basis for predicting future 
outcomes. Reserve amounts are necessarily based on management’s informed estimates and judgments using currently available 
data. As additional experience and other data become available and are reviewed, these estimates and judgments may be 
revised. This may result in reserve increases or decreases that would be reflected in our results in periods in which such 
estimates and assumptions are changed.

The risk and complexity of estimating loss reserves are greater when economic conditions are uncertain. It is 

especially difficult to estimate the impact of inflation on loss reserves given the current economic environment and related 
government actions. Whereas a slowing economy would generally lead to lower inflation or even deflation, increased 
government spending would generally lead to higher inflation. A change in our assumptions regarding inflation would result in 
reserve increases or decreases that would be reflected in our earnings in periods in which such assumptions are changed.

Reserves do not represent an exact calculation of liability. Rather, reserves represent an estimate of what management 

expects the ultimate settlement and claim administration will cost. While the methods for establishing the reserves are well 
tested over time, some of the major assumptions about anticipated loss emergence patterns are subject to unanticipated 
fluctuation. These estimates, which generally involve actuarial projections, are based on management’s assessment of facts and 
circumstances then known, as well as estimates of trends in claims severity and frequency, judicial theories of liability and other 
factors, including the actions of third parties, which are beyond the Company’s control. These variables are affected by external 
and internal events, such as inflation and economic volatility, judicial and litigation trends, reinsurance coverage, legislative 
changes and claim handling and reserving practices, which make it more difficult to accurately predict claim costs. The inherent 
uncertainties of estimating reserves are greater for certain types of liabilities where long periods of time elapse before a 
definitive determination of liability is made. Although the loss reserves included in the Company’s financial statements 
represent management’s best estimates, setting reserves is inherently uncertain and the Company cannot provide assurance that 
its current reserves will prove adequate in light of subsequent events.

17

 
 
The Company discounts its liabilities for certain workers’ compensation reserves. The amount of workers’ 
compensation reserves that were discounted was $1,352 million and $1,464 million at December 31, 2023 and 2022, 
respectively. The aggregate net discount for those reserves, after reflecting the effects of ceded reinsurance, was $390 million 
and $416 million at December 31, 2023 and 2022, respectively. At December 31, 2023, discount rates by year ranged from 
0.7% to 6.5%, with a weighted average discount rate of 3.5%. 

Substantially all discounted workers’ compensation reserves (97% of total discounted reserves at December 31, 2023) 

are excess workers’ compensation reserves. In order to properly match loss expenses with income earned on investment 
securities supporting the liabilities, reserves for excess workers’ compensation business are discounted using risk-free discount 
rates determined by reference to the U.S. Treasury yield curve. These rates are determined annually based on the weighted 
average rate for the period. Once established, no adjustments are made to the discount rate for that period, and any increases or 
decreases in loss reserves in subsequent years are discounted at the same rate, without regard to when any such adjustments are 
recognized. The expected loss and loss expense payout patterns subject to discounting are derived from the Company’s loss 
payout experience.  

The Company also discounts reserves for certain other long-duration workers’ compensation reserves (representing 

approximately 3% of total discounted reserves at December 31, 2023), including reserves for quota share reinsurance and 
reserves related to losses regarding occupational lung disease. These reserves are discounted at statutory rates permitted by the 
Department of Insurance of the State of Delaware.

To date, known environmental and asbestos claims have not had a material impact on the Company’s operations, 
because its subsidiaries generally did not insure large industrial companies that are subject to significant environmental or 
asbestos exposures prior to 1986 when an absolute exclusion was incorporated into standard policy language.

The Company’s net reserves for losses and loss expenses relating to environmental and asbestos claims on policies 

written before adoption of the absolute exclusion was $17 million and $20 million at December 31, 2023 and 2022, 
respectively. The estimation of these liabilities is subject to significantly greater than normal variation and uncertainty because 
it is difficult to make an actuarial estimate of these liabilities due to the absence of a generally accepted actuarial methodology 
for these exposures and the potential effect of significant unresolved legal matters, including coverage issues, as well as the cost 
of litigating the legal issues. Additionally, the determination of ultimate damages and the final allocation of such damages to 
financially responsible parties are highly uncertain.

(1) For statutory purposes, the Company discounts its workers’ compensation reinsurance reserves at 2.5% as prescribed or 
permitted by the Department of Insurance of the State of Delaware. In its GAAP financial statements, the Company 
discounts excess workers’ compensation reserves at the risk-free rate and assumed workers’ compensation reserves at the 
statutory rate.

Reinsurance

We follow a common industry practice of reinsuring a portion of our exposures and paying to reinsurers a portion of the 
premiums received on the policies that we write. Reinsurance is purchased principally to reduce net liability on individual risks 
and to protect against catastrophic losses. Although reinsurance does not legally discharge an insurer from its primary liability 
for the full amount of the policies, it does make the assuming reinsurer contractually liable to the insurer to the extent of the 
reinsurance coverage. We monitor the financial condition of our reinsurers and attempt to place our coverages only with 
substantial, financially sound carriers. As a result, generally the reinsurers who reinsure our casualty insurance must have an 
A.M. Best rating of “A (Excellent)” or better with at least $1 billion in policyholder surplus and the reinsurers who cover our 
property insurance must have an A.M. Best rating of “A- (Excellent)” or better with at least $1 billion in policyholder surplus.

Regulation

U.S. Regulation 

Our U.S. insurance subsidiaries are principally regulated by their domiciliary state insurance departments and are subject 

to varying degrees of regulation and supervision in the other U.S. jurisdictions in which they do business. As of January 1, 
2024, there are six domiciliary states related to our U.S. insurance subsidiaries.

Overview. Our domestic insurance subsidiaries are subject to statutes which delegate regulatory, supervisory and 

administrative powers to state insurance commissioners. This regulation relates to such matters as the standards of solvency 
which must be met and maintained; the licensing of insurers and their agents; the nature of and limitations on investments; 
deposits of securities for the benefit of policyholders; approval of certain policy forms and premium rates; periodic examination 
of the affairs of insurance companies; annual and other reports required to be filed on the financial condition of insurers or for 
other purposes; establishment and maintenance of reserves for unearned premiums, loss expenses and losses; and requirements 
regarding numerous other matters. Our property casualty subsidiaries, other than our excess and surplus lines and reinsurance 
subsidiaries, must generally file all rates with the insurance department of each state in which they operate. Our excess and 
surplus lines and reinsurance subsidiaries generally operate free of rate and form regulation.

19

 
 
 
 
Holding Company Statutes. In addition to regulatory supervision of our insurance subsidiaries, we are subject to state 

statutes governing insurance holding company systems. Under the terms of applicable state statutes, any person or entity 
desiring to purchase more than a specified percentage (commonly 10%) of our outstanding voting securities would be required 
to obtain prior regulatory approval of the purchase. Typically, such statutes require that we periodically file information with 
the appropriate domiciliary state insurance commissioner, including information concerning our capital structure, ownership, 
financial condition and general business operations. 

We must also annually submit to the lead state regulator for our group an “enterprise risk management report” which 

identifies the activities and circumstances of any affiliated company that might have a material adverse effect on the financial 
condition of our group or our U.S. licensed insurers. 

In addition, all states have adopted changes to the holding company act that authorize U.S. insurance regulators to lead or 

participate in the group-wide supervision of certain international insurance groups. In November 2019, the International 
Association of Insurance Supervisors (“IAIS”), an international standard setter, adopted a global framework for the supervision 
of internationally active insurance groups (“IAIGs”), as discussed below under “International Regulation.” This framework 
includes a risk-based, group-wide global insurance capital standard (“ICS”), which is undergoing a five-year monitoring period 
that started in January 2020. We have received notice from Delaware, our lead state insurance regulator, that we may be 
considered an IAIG. In the event that we are deemed to be an IAIG, we would be subject to international oversight coordinated 
by the Delaware Department of Insurance.

In the United States, the National Association of Insurance Commissioners (the “NAIC”) has developed a group capital 
calculation tool that uses a risk-based capital aggregation methodology for all entities in an insurance holding company system. 
The goal is to provide U.S. regulators with a method to aggregate the available capital and the minimum capital of each entity 
in a group in a way that applies to all companies regardless of their structure. In 2022, Delaware, our lead state regulator, 
adopted the NAIC amendments to the model holding company act and regulation that require the ultimate controlling person of 
an insurer subject to holding company registration to submit the group capital calculation filing annually with its lead state 
regulator.

All states have adopted the NAIC's Risk Management and Own Risk and Solvency Assessment Model Act (the “ORSA 

Model Act”), which requires an insurance holding company system’s chief risk officer to submit annually to its lead state 
insurance regulator an Own Risk and Solvency Assessment Summary Report (“ORSA Report”). The ORSA Report is a 
confidential internal assessment of the material and relevant risks associated with an insurer’s current business plan and the 
sufficiency of capital resources to support those risks. Under the ORSA Model Act, as enacted by the states, we are required to:

•

•

•

regularly, no less than annually, conduct an Own Risk and Solvency Assessment to assess the adequacy of our risk 
management framework, and current and estimated projected future solvency position;
internally document the process and results of the assessment; and

provide an ORSA Report annually to the State of Delaware's Insurance Commissioner.

Cybersecurity Regulations. New York’s cybersecurity regulation applies to financial services institutions authorized by 

the New York State Department of Financial Services (the “NYDFS”), including our insurance subsidiaries licensed in New 
York. The regulation requires these entities to assess risks associated with their information systems and establish and maintain 
a cybersecurity program reasonably designed to protect consumers’ private data and the confidentiality, integrity and 
availability of the licensee’s information systems. On November 1, 2023, the NYDFS adopted amendments to New York’s 
cybersecurity regulation, which require additional reporting, governance and oversight measures, and enhanced cybersecurity 
safeguards to be implemented. The amendments take effect in phases that began in 2023 and continue through 2025.

The NAIC has adopted the Insurance Data Security Model Law (the “Cybersecurity Model Law”) for consideration by 

state legislatures, which establishes standards for data security, the investigation of cybersecurity events involving the 
unauthorized access to, or misuse of, certain nonpublic information, and reporting to insurance commissioners. The 
Cybersecurity Model Law imposes significant regulatory burdens intended to protect the confidentiality, integrity and 
availability of information systems. As of December 31, 2023, the Cybersecurity Model Law, or a form thereof, had been 
adopted by several states, including three of our U.S. insurance subsidiaries’ domiciliary states. A drafting note in the 
Cybersecurity Model Law states that a licensee’s compliance with New York's cybersecurity regulation is intended to constitute 
compliance with the Cybersecurity Model Law, but compliance remains a state-by-state issue requiring consideration of any 
State differences in implementation and enforcement of the Cybersecurity Model Law. 

20

Certain other states have enacted or are considering laws and regulations related to privacy and data security. For 
example, the California Consumer Privacy Act (“CCPA”), broadly regulates the collection, processing and disclosure of 
California residents’ personal information, imposes limits on the “sale” of personal information and grants California residents 
certain rights to, among other things, access and delete data about them in certain circumstances. The CCPA also established a 
private right of action, with potentially significant statutory damages, whereby businesses that fail to implement reasonable 
security measures to protect against breaches of personal information could be liable to affected California consumers. 
California subsequently enacted the California Privacy Rights Act (“CPRA”), which came into full effect in January 2023 and 
amended the CCPA by imposing additional limitations and obligations with respect to covered businesses’ use and sharing of 
certain personal data. Compliance with the CCPA/CPRA may increase the cost of providing our products and services in 
California. An increasing number of U.S. states have adopted, or are considering legislation similar to the CCPA. 
Additionally, the NAIC is working on a new Insurance Consumer Privacy Protections Model Law to 
reflect the extensive innovations in communications and technology since the adoption of the prior model laws.

We cannot predict the impact, if any, that any current, proposed or future federal or state cybersecurity laws or 

regulations will have on our business, financial condition or results of operations.

Innovation and Technology. As a result of increased innovation and use of technology in the insurance sector, the 

NAIC and insurance regulators have been focusing on the use of “big data” techniques, such as artificial intelligence, machine 
learning and automated decision-making. In December 2023, the NAIC adopted the Model Bulletin on the Use of Artificial 
Intelligence Systems by Insurers (the “AI Bulletin”). The AI Bulletin may be adopted and issued by state regulators to licensed 
insurers. In addition to affirming that the use of artificial intelligence must comply with existing state law, the AI Bulletin sets 
forth regulators’ expectations on how insurers will develop, acquire and use artificial intelligence technologies. In 2024, the 
NAIC plans to form a new task force to create a regulatory framework for the oversight of insurers’ use of third-party data and 
models.

The NAIC and state insurance regulators are also focused on addressing unfair discrimination by insurers in the use of 

consumer data and technology, and certain states have passed laws or are considering action targeting unfair discrimination 
practices. For example, in 2021 Colorado enacted a law that prohibits insurers from using external consumer data and 
information sources (“ECDIS”), as well as algorithms or predictive models that use ECDIS, in a way that unfairly discriminates 
based on race, color, national or ethnic origin, religion, sex, sexual orientation, disability, gender identity or gender expression. 
In August 2023, Colorado adopted regulations requiring life insurers to adopt a governance and risk management framework 
for the use of artificial intelligence, machine learning and other technologies that utilize “external consumer data.” It is expected 
that Colorado will also adopt governance and testing regulations for other lines of insurance, in accordance with the 
requirements of its 2021 law.

We cannot predict whether states will adopt the AI Bulletin, or what, if any, changes to laws or regulations may be 

enacted with regard to “big data” or artificial intelligence technologies. 

Risk-Based Capital Requirements. The NAIC utilizes a Risk-Based Capital (“RBC”) formula that is designed to 

measure the adequacy of an insurer's statutory surplus in relation to the risks inherent in its business. The RBC formula 
develops a risk adjusted target level of adjusted statutory capital by applying certain factors to various asset, premium and 
reserve items. The NAIC RBC Model Law provides for four incremental levels of regulatory attention for insurers whose 
surplus is below the calculated RBC target. These levels of attention range in severity from requiring the insurer to submit a 
plan for corrective action to actually placing the insurer under regulatory control. The RBC of each of our domestic insurance 
subsidiaries was above the calculated RBC target level as of December 31, 2023. 

Insurance Regulatory Information System. The NAIC also has developed a set of 13 financial ratios for property and 

casualty insurers referred to as the Insurance Regulatory Information System (“IRIS”). On the basis of statutory financial 
statements filed with state insurance regulators, the NAIC annually calculates these IRIS ratios to assist state insurance 
regulators in monitoring the financial condition of insurance companies. The NAIC has established an acceptable range for each 
of the IRIS financial ratios.

Guaranty Funds. Our U.S. insurance subsidiaries are also subject to assessment by state guaranty funds in states where 

we transact admitted business when an insurer in a particular jurisdiction has been judicially declared insolvent and the 
insolvent company's available funds are insufficient to pay policyholders and claimants the amounts to which they are entitled. 
The protection afforded under a state's guaranty fund to policyholders of the insolvent insurer varies from state to state. 
Generally, all licensed property casualty insurers are considered to be members of the fund, and assessments are based upon 
their pro rata share of direct written premiums in that state. The NAIC Post-Assessment Property and Liability Insurance 
Guaranty Association Model Act, a version of which has been adopted by all states, limits assessments to 2% of an insurer’s 
subject premiums and permits recoupment of assessments through rate setting. Likewise, several states (or underwriting 

21

organizations of which our insurance subsidiaries are required to be members) have limited assessment authority with regard to 
deficits in certain lines of business.

Additionally, state insurance laws and regulations require us to participate in mandatory property-liability “shared 

market,” “pooling” or similar arrangements that provide certain types of insurance coverage to individuals or others who 
otherwise are unable to purchase coverage voluntarily provided by private insurers. Shared market mechanisms include 
assigned risk plans and fair access to insurance requirement or “FAIR” plans. In addition, some states require insurers to 
participate in reinsurance pools for claims that exceed specified amounts. Our participation in these mandatory shared market or 
pooling mechanisms generally is related to the amount of our direct writings for the type of coverage written by the specific 
mechanism in the applicable state. 

Dividends. We receive funds from our insurance company subsidiaries in the form of dividends and management fees 
for certain management services. Annual dividends in excess of maximum amounts prescribed by state statutes may not be paid 
without the approval of the insurance commissioner of the state in which an insurance subsidiary is domiciled. See 
“Management's Discussion and Analysis of Financial Condition and Results of Operations-Liquidity and Capital Resources.” 

Trade Practices. State insurance laws and regulations include numerous provisions governing trade practices and the 
marketplace activities of insurers, including provisions governing marketing and sales practices, policyholder services, claims 
management and complaint handling. State regulatory authorities generally enforce these provisions through periodic market 
conduct examinations.

Investment Regulation. Investments by our domestic insurance companies must comply with applicable laws and 

regulations which prescribe the kind, quality and concentration of investments. In general, these laws and regulations permit 
investments in federal, state and municipal obligations, corporate bonds, preferred and common equity securities, mortgage 
loans, real estate and certain other investments, subject to specified limits and certain other qualifications. Investments that do 
not comply with these limits and qualifications are deducted in our insurance subsidiaries' calculation of their statutory capital 
and surplus.

Terrorism Risk Insurance. The Terrorism Risk Insurance Act of 2002 established a Federal program that provides for a 

system of shared public and private compensation for insured losses resulting from acts of terrorism. Pursuant to the Terrorism 
Risk Insurance Program Reauthorization Act of 2019 (“TRIPRA”), the program was extended until December 31, 2027.

TRIPRA provides a federal backstop to all U.S. based property and casualty insurers for insurance related losses 
resulting from any act of terrorism on U.S. soil or against certain U.S. air carriers, vessels or foreign missions. TRIPRA is 
applicable to almost all commercial lines of property and casualty insurance but excludes auto, burglary and theft, surety, 
professional liability and farm owners' multi-peril insurance. Insurers with direct commercial property and casualty insurance 
exposure in the United States are required to participate in the program and make available coverage for certified acts of 
terrorism. TRIPRA's definition of certified acts includes domestic terrorism. Federal participation will be triggered under 
TRIPRA when the Secretary of Treasury certifies an act of terrorism. 

Under the program, the federal government will pay 80% of an insurer's covered losses in excess of the insurer's 

applicable deductible. The insurer's deductible is calculated as 20% of earned premium for the prior year for covered lines of 
commercial property and casualty insurance. Based on our 2023 earned premiums, our aggregate deductible under TRIPRA 
during 2024 will be approximately $1,464 million. The federal program will not pay losses for certified acts unless such losses 
exceed $200 million industry-wide for any calendar year. TRIPRA limits the federal government's share of losses at 
$100 billion for a program year. In addition, an insurer that has satisfied its deductible is not liable for the payment of losses in 
excess of the $100 billion cap.

Excess and Surplus Lines. The regulation of our U.S. subsidiaries' excess and surplus lines insurance business differs 

significantly from the regulation of our admitted business. Our surplus lines subsidiaries are subject to the surplus lines 
regulation and reporting requirements of the jurisdictions in which they are eligible to write surplus lines insurance. Although 
surplus lines business is generally less regulated than admitted business, principally with respect to rates and policy forms, strict 
regulations apply to surplus lines placements in the laws of every state and the regulation of surplus lines insurance may 
undergo changes in the future. Federal or state measures may be introduced to increase the oversight of surplus lines insurance 
in the future.

Climate Change and Financial Risks. The NAIC and state insurance regulators continue to evaluate issues related to 

the management of climate risk. In 2022, the NAIC adopted a new standard for insurance companies to report their climate-
related risks as part of its annual Climate Risk Disclosure Survey, which applies to insurers that meet the reporting threshold of 
$100 million in U.S. direct premium and are licensed in one of the participating jurisdictions. The NYDFS’s 2020 circular 
letter, which applies to our insurance subsidiaries licensed in New York, states that regulated insurers are expected to integrate 

22

financial risks related to climate change into their governance frameworks, risk management processes, business strategies and 
scenario analysis, and develop their approach to climate-related financial disclosure. For example, an insurer should designate a 
board member or board committee, as well as a senior management function, to oversee the management of financial risks 
associated with climate change. The NYDFS also adopted an amendment to the regulation governing enterprise risk 
management, which applies to our insurance subsidiaries licensed in New York, that requires an insurance group's enterprise 
risk management function to address certain additional risks, including climate change risk.  

In addition, the Federal Insurance Office (the “FIO”) is authorized to monitor the U.S. insurance industry under the 
Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”), as discussed below under 
“Federal Regulation.” Pursuant to this statutory authority, the FIO is assessing how the insurance sector may mitigate climate 
risks and help achieve national climate-related goals. In June 2023, the FIO released a report urging insurance regulators to 
adopt climate-related risk-monitoring guidance in order to enhance their regulation and supervision of insurers. 

Diversity and Corporate Governance.The NAIC and state insurance regulators also continue to evaluate issues related 

to diversity within the insurance industry, such as the diversity of an insurer’s board of directors and management. In March 
2021, the NYDFS issued a circular letter stating that it expects the insurers it regulates, such as our insurance subsidiaries 
licensed in New York, to make diversity of their leadership a business priority and a key element of their corporate governance, 
and it includes diversity-related questions in its examination process. In addition, the NAIC is examining practices in the 
insurance industry in order to determine how barriers are created that disadvantage or discriminate against people of color or 
historically underrepresented groups. NAIC goals include improving access to different types of insurance products in minority 
communities, addressing issues related to affordability, and providing guidance to regulators on ways to improve insurance 
access and the understanding of insurance in underserved communities.  See “Human Capital Resources” below.

Federal Regulation. The federal government and its regulatory agencies generally do not directly regulate the business 

of insurance, although federal initiatives could have an impact on our business in a variety of ways. The Dodd-Frank Act 
effected sweeping changes to financial services regulation in the United States, and created two new federal government bodies, 
the FIO and the Financial Stability Oversight Council (the “FSOC”). The FIO does not have general supervisory or regulatory 
authority over the business of insurance, although it has preemption authority over state insurance laws that conflict with certain 
international agreements, as discussed below. The FIO also has authority to represent the United States in international 
insurance matters and is authorized to monitor the U.S. insurance industry and identify potential regulatory gaps that could 
contribute to systemic risk. The Economic Growth, Regulatory Relief and Consumer Protection Act of 2018 addresses the roles 
played by federal regulators at international insurance standard-setting forums, and it directs the Director of the FIO and the 
Board of Governors of the Federal Reserve to support increased transparency at international standard-setting regulatory forums 
(e.g., the IAIS). These federal regulations also instruct the FIO and the Federal Reserve to achieve consensus positions with the 
states through the NAIC prior to taking a position on any insurance proposal by a global insurance regulatory forum.  

The Dodd-Frank Act authorizes the Secretary of the Treasury and U.S. Trade Representative to enter into international 

agreements of mutual recognition regarding the prudential regulation of insurance or reinsurance. The U.S. and the European 
Union ("EU") signed such a covered agreement (the "EU Covered Agreement") in September 2017, which addresses three areas 
of prudential supervision: reinsurance, group supervision and the exchange of information between the U.S. and EU. 

In December 2018, the U.S. Department of the Treasury and the Office of the U.S. Trade Representative entered into a 
covered agreement with the U.K. (the “U.K. Covered Agreement,” and together with the EU Covered Agreement, the “Covered 
Agreements”) in anticipation of the U.K.’s exit from the EU. The U.K. Covered Agreement largely reflects the provisions of the 
EU Covered Agreement and incorporates the same timeframes within it. 

Under the Dodd-Frank Act, the FIO has preemption authority over state insurance laws that conflict with the Covered 

Agreements as of September 1, 2022, such as state credit for reinsurance laws that result in non-U.S. reinsurers subject to the 
Covered Agreements being treated less favorably than U.S. reinsurers. The NAIC previously adopted amendments to its Credit 
for Reinsurance Model Law to satisfy the substantive and timing requirements of the Covered Agreements, which amendments 
have been enacted by all states. On September 30, 2023, the FIO reported that it did not recommend taking any preemption 
action as a result of inconsistency between the Covered Agreements and state credit for reinsurance laws, although it is still 
monitoring state measures implementing the NAIC’s revisions to the Credit for Reinsurance Model Law. Under the Covered 
Agreements, reinsurance collateral requirements no longer apply to qualifying EU and U.K. reinsurers. The amended Credit for 
Reinsurance Model Law also extends the zero reinsurance collateral provisions in the Covered Agreements to qualified 
reinsurers domiciled in U.S. jurisdictions that are accredited by the NAIC and to non-U.S. jurisdictions that have not entered 
into a covered agreement with the U.S. but which the NAIC has identified as “reciprocal jurisdictions” pursuant to the NAIC 
Qualified Jurisdiction Process. 

23

We cannot currently predict the impact of these changes to the law or whether any other covered agreements will be 

successfully adopted, and cannot currently estimate the impact of these changes to the law and any such adopted covered 
agreements on our business, financial condition or operating results.

The Dodd-Frank Act authorizes the FSOC to designate an insurer as a “systemically important financial institution” or 

a “non-bank SIFI” if the insurer’s material financial distress could pose a systemic risk to the financial system or the nature or 
scale of its activities could pose a threat to U.S. financial stability. The FIO can recommend that an insurer be designated as a 
non-bank SIFI, which would subject the company to Federal Reserve supervision and heightened prudential standards. There 
are currently no such non-bank SIFIs designated by the FSOC. In November 2023, the FSOC adopted final guidance that 
establishes a new process for designating certain financial companies as non-bank SIFIs. The revised process is based on the 
consideration of risk factors set forth in a new analytic framework, which describes how the FSOC intends to monitor a broad 
range of institutions and activities and respond to potential risks to U.S. financial stability. The financial vulnerabilities that 
most often contribute to this type of risk include leverage, liquidity risk and maturity mismatch, inadequate risk management, 
concentration and destabilizing activities. Under the new guidance, the FSOC is no longer required to conduct a cost-benefit 
analysis and an assessment of the likelihood of a non-bank financial company’s material financial distress before considering 
the designation of the company. The revised process could have the effect of simplifying and shortening FSOC’s procedures for 
designating certain financial companies as non-bank SIFIs.

Based upon our current business model and balance sheet, we do not believe that we will be designated by the FSOC 
as such an institution. Although the potential impact of any future amendments to the Dodd-Frank Act on the U.S. insurance 
industry is not clear, our business could be affected by changes to the U.S. system of insurance regulation or our designation or 
the designation of insurers or reinsurers with which we do business as non-bank SIFIs. 

Legislative and Regulatory Activity Related to the COVID-19 Pandemic or Other Potential Pandemics. In response to 

the outbreak of the COVID-19 pandemic in 2020, legislators in several states and in the United States Congress introduced 
proposals that would have mandated insurance coverage for certain pandemic-related losses, including business interruption 
losses, or that would have established a federal insurance program for addressing pandemic risk. None of these proposals were 
enacted. However, there remains some risk that in the event of another pandemic event, whether related to COVID-19 or 
another contagious disease, Congress could take similar actions.  See “Risk Factors — Risks Related to Our Industry — The 
COVID-19 pandemic materially and adversely affected our results of operations, and, whether as a result of COVID-19's long-
term effects, or new or emerging variants, or other potential pandemics, may further materially and adversely affect our results 
of operations, financial position and liquidity in the future."

International Regulation

Our insurance subsidiaries based in the United Kingdom are regulated by the Prudential Regulation Authority (“PRA”) 

and/or the Financial Conduct Authority (“FCA”). The PRA’s primary objectives with regard to insurers are to promote the 
safety and soundness of insurers and to contribute to the securing of an appropriate degree of protection for current and future 
policyholders. The FCA has three operational objectives: (i) to secure an appropriate degree of protection for consumers, (ii) to 
protect and enhance the integrity of the United Kingdom’s financial system, and (iii) to promote effective competition in the 
interests of consumers in the financial services markets. The PRA and FCA employ a variety of regulatory tools to achieve their 
objectives, including periodic auditing and reporting requirements, risk assessment reviews, minimum solvency margins and 
individual capital assessment requirements, dividend restrictions, in certain cases, approval requirements governing the 
appointment of key officers, approval requirements governing controlling ownership interests and various other requirements.

Our Lloyd’s managing agency is also regulated by Lloyd’s, and the Lloyd’s syndicate business is subject to Lloyd’s 

supervision. Through Lloyd’s, we are licensed to write business in various countries throughout the world by virtue of Lloyd’s 
international licenses. In each such country, we are subject to the laws and insurance regulation of that country. Our insurance 
subsidiary based in Liechtenstein is regulated by the Financial Market Authority of Liechtenstein ("FMA"), which has 
regulatory tools analogous to those of the U.K. regulators noted above.

Additionally, U.K. and Liechtenstein laws and regulations also impact us as “controllers” of our European-regulated 
subsidiaries, whereby we are required to notify the appropriate authorities about significant events relating to such regulated 
subsidiaries’ controllers (i.e. persons or entities which have certain levels of direct or indirect voting power or economic 
interests in the regulated entities) as well as changes of control, and to submit annual reports regarding their controllers. The 
PRA/FCA’s Senior Managers and Certification Regime and analogous regulation in Liechtenstein further provide regulatory 
frameworks for standards of fitness and propriety, conduct and accountability for individuals in positions of responsibility at 
insurers. In addition, certain employees are individually registered at Lloyd’s.

24

Our insurance business throughout the EU and EEA is subject to “Solvency II,” an insurance regulatory regime 
governing, among other things, capital adequacy and risk management. Following the U.K.’s withdrawal from the EU, or 
Brexit, our Lloyd’s managing agency (and the U.K. branch of our Liechtenstein subsidiary) are now subject to a separate U.K. 
prudential regime, which is broadly identical to Solvency II but will diverge from Solvency II in the future. The U.K. has 
recently adopted legislative reforms that amended various parts of the U.K.’s prudential regime, including the risk margin, 
matching adjustment requirements and regulatory reporting obligations. The legislative reforms relating to the risk margin took 
effect from December 31, 2023, and other areas of reform will come into force throughout 2024.

Similarly, the EU’s legislative bodies have undertaken a review of Solvency II. In September 2021, the European 

Commission published a package of proposed legislative reforms for amending the existing regulatory framework. The 
legislative bodies reached a provisional agreement on the revised text of Solvency II in December 2023. A finalized set of rules 
will now be prepared, which EU member states will implement into their domestic legislation. 

Solvency II provides for the supervision of group solvency. Under Solvency II, it is possible that the U.S. parent of a 
European Union subsidiary could be subject to certain Solvency II requirements if the U.S. company is not already subject to 
regulations deemed “equivalent” to Solvency II. Currently, the U.S. system of insurance regulation relating to group 
supervision is not deemed “equivalent” to Solvency II by European Union authorities. The PRA will also perform separate, but 
comparable, supervision of group solvency under the U.K.’s own domestic prudential regime where a U.S. holding company is 
a parent of a subsidiary U.K. insurer or reinsurer.

The Liechtenstein financial services regulator, the FMA, is the group supervisor for our European-regulated 
subsidiaries. However, the Covered Agreements prohibit any EU supervisor or the PRA (as applicable) from exercising group-
wide supervision at any level above the highest company organized in the country of that supervisor.

We must also comply with the EU General Data Protection Regulation (EU) 2016/879) (“GDPR”), which took effect 

in May 2018, including EEA member state legislation implementing the GDPR. The regulation’s goal is to impose increased 
individual rights and protections for all personal data located in or originating from the EU. The Data Protection Act 2018 and 
the U.K. General Data Protection Regulation, which is the retained EU law version of the GDPR by virtue of the European 
Union (Withdrawal) Act 2018 and as amended by the Data Protection, Privacy and Electronic Communications (Amendments 
etc.) (EU Exit) Regulations 2019 (together, “U.K. GDPR”), regulate data protection for all individuals within the U.K. Both the 
GDPR and the U.K. GDPR are extraterritorial in that they apply to all businesses in the EU and the U.K. respectively and any 
business outside the EU and the U.K. that offers services, or monitors the behavior of individuals, in the EU and/or U.K., and 
that processes the personal data of individuals in the EU and/or the U.K. Moreover, there are significant fines associated with 
non-compliance. In particular, we need to monitor our compliance with all relevant member states’ laws and regulations, 
including where permitted derogations from the GDPR and the U.K. GDPR are introduced. The introduction of the GDPR and 
the U.K. GDPR, and any resultant changes in EU member states’ or U.K. national laws and regulations, has increased our 
compliance obligations and has necessitated the review and implementation of policies and processes relating to our collection 
and use of data, and has required us to change our business practices regarding these matters.

In addition, we may become subject to or affected by regulatory policies adopted by the IAIS, an international standard 

setter consisting of supervisors and regulators from more than 200 jurisdictions. The IAIS has been working on several 
initiatives to consider changes to insurer solvency standards and group supervision of companies in a holding company system 
in response to the increasing globalization of the insurance sector. In November 2019, the IAIS formally adopted a global 
framework for the supervision of IAIGs, which is referred to as the Common Framework for the Supervision of Internationally 
Active Insurance Groups, or “ComFrame.” ComFrame is intended to provide a framework of basic standards for IAIGs and a 
process for supervisors to cooperate in the supervision of IAIGs. Also in November 2019, the IAIS adopted a risk-based group-
wide global insurance capital standard (“ICS”) that will apply to IAIGs and ultimately form a part of ComFrame. The ICS 
commenced a five-year monitoring period in January 2020 which is being used for confidential reporting and discussion in 
supervisory colleges to provide feedback to the IAIS on the ICS’s design and performance, but will not trigger any supervisory 
action. Following this monitoring period, the ICS is expected to be implemented in 2025 as a group-wide prescribed capital 
requirement for IAIGs and integrated into the rest of ComFrame. The IAIS is also conducting a comparability assessment to 
determine whether an aggregation method approach to a group capital standard, which forms part of the NAIC’s group capital 
calculation, produces comparable outcomes to the ICS. As noted above under “U.S. Regulation,” it is unclear how the 
development of the ICS will interact with existing capital requirements for insurance companies in the United States and the 
NAIC’s development of the group capital calculation. We have received notice from Delaware, our lead state insurance 
regulator, that we may be considered an IAIG. In the event that we are deemed to be an IAIG, we would be subject to 
international oversight coordinated by the Delaware Department of Insurance.

Our international operations are also subject to varying degrees of regulation in Mexico, Australia and Canada and in 

certain other countries in Europe, South America, and Southeast Asia. Generally, our subsidiaries must satisfy local regulatory 

25

requirements. While each country imposes licensing, solvency, auditing and financial reporting requirements, the type and 
extent of the requirements differ substantially. Key areas where country regulations may differ include: (i) the type of financial 
reports to be filed; (ii) a requirement to use local intermediaries; (iii) the amount of reinsurance permissible; (iv) the scope of 
any regulation of policy forms and rates; and (v) the type and frequency of regulatory examinations.

Competition 

The property casualty insurance and reinsurance businesses are highly competitive, with many insurance companies of 
various sizes, as well as other entities offering risk alternatives such as self-insured retentions or captive programs, transacting 
business in the United States and internationally. We compete directly with a large number of these companies. Competition in 
our industry is largely measured by the ability to provide insurance and services at a price and on terms that are reasonable and 
acceptable to the customer. Our strategy in this highly fragmented industry is to seek specialized areas or geographic regions 
where our businesses can gain a competitive advantage by responding quickly to changing market conditions. Our businesses 
establish their own pricing practices based upon a Company-wide philosophy to price products with the intent of making an 
underwriting profit. 

Competition for insurance business within the United States comes from other specialty insurers, regional carriers, large 

national multi-line companies and reinsurers. Our specialty businesses compete with excess and surplus insurers as well as 
standard carriers. Our regional businesses compete with mutual and other regional stock companies as well as national carriers. 
Additionally, direct writers of property casualty insurance compete with our regional businesses by writing insurance through 
their salaried employees, generally at a lower acquisition cost than through independent agents such as those used by the 
Company. We compete internationally with native insurance operations both large and small, which in some cases are related to 
government entities, as well as with branches or local subsidiaries of multinational companies.

Competition for reinsurance business, which is especially strong, comes from domestic and foreign reinsurers, which 

produce their business either on a direct basis or through the broker market. These competitors include Swiss Re, Munich Re, 
Berkshire Hathaway, Partner Re and others. 

 In recent years, various institutional investors have increasingly sought to participate in the property and casualty 

insurance and reinsurance industries. Well-capitalized new entrants to the property and casualty insurance and reinsurance 
industries, or existing competitors that receive substantial infusions of capital, provide increasing competition, which may 
adversely impact our business and profitability. Further, an expanded supply of reinsurance capital may lower costs for insurers 
that rely on reinsurance and, as a consequence, those insurers may be able to price their products more competitively. 

Human Capital Resources  

As of January 15, 2024, we employed 8,329 individuals. Of this number, our subsidiaries employed 8,194 individuals 

and the remaining individuals were employed at the parent company. 

We believe that our people are our greatest asset and that our corporate culture is the most important intangible driver of 

long-term value creation for our Company and the highest priority for pursuing long-term risk-adjusted returns and growth in 
stockholder value.

Human Capital Management: The Company fosters a performance culture. We are focused on creating a respectful, 

rewarding, diverse, and inclusive work environment that allows our employees to build meaningful and productive careers. The 
success of these human capital management objectives is essential to our strategy, as it is our people who drive our success. We 
invest in their growth as individuals and professionals through training and engagement, as well as in their well-being through 
robust health and wellness programs and a commitment to diversity. 

The Company provides developmental opportunities for our employees through formal and informal programs that focus 

on enabling employees to build skills and thought leadership in specific facets of our business. Our leadership programs 
cultivate the talent of our high-potential, strong-performing employees as we strive to deepen, enhance and diversify the 
Company’s leadership team. 

We strive to align employee incentives with the risk and performance frameworks of the Company. The Company’s “pay 

for performance” philosophy connects individual, business and Company results to employee compensation, providing 
employees with opportunities to share in the Company’s overall growth and success. The Company offers employees a 
comprehensive benefits package, including health and wellness, financial, educational and life management benefits. In 
addition, we support employees in making an impact in their local communities and globally through environmental and social 
efforts that are meaningful to them. 

26

Our Board of Directors engages with our senior leadership team, including our senior vice president - human resources, 

on a periodic basis across a range of human capital management issues, including succession planning and development, 
compensation, benefits, talent recruiting and retention, engagement, diversity and inclusion, and employee feedback. 

Culture: The Board of Directors has recognized Accountability, People Oriented Strategy, Responsible Financial 
Practices, Risk-Adjusted Returns and Transparency as the elements of corporate culture necessary for the Company to achieve 
success. Our culture unifies our employees across our decentralized business model, positions us to serve our diverse clients 
globally and propels the Company’s continuous evolution.

We are committed to fostering a unifying culture and encouraging innovation across our enterprise. Our culture 
encompasses the beliefs that (i) specialized knowledge and having a customer-centric focus are competitive advantages and (ii) 
an environment that promotes integrity, embraces the commitment to “always do right,” fosters entrepreneurship and 
innovation, and values making thoughtful decisions for the long-term benefit of our enterprise. While there is no one “Berkley” 
way, each of our businesses has its own culture that embodies a shared set of values that define our enterprise. Our structure, 
with 60 distinct businesses, facilitates the prompt identification of and appropriate action with respect to addressing individual 
business or cultural issues arising within a business, without affecting the larger enterprise. Furthermore, our businesses are 
overseen by senior corporate business managers and senior corporate functional managers, including actuarial, underwriting, 
compliance and finance, providing a governance oversight structure that makes it easier to identify such issues. Because our 
Board of Directors diligently exercises its risk management oversight through, among other activities, regular interactions with 
employees beyond corporate senior management, our directors have visibility into and receive timely feedback on cultural 
issues that may affect our business.

As significant owners of our Company who are required to hold their shares until separation from service, each of our 

directors and senior executives have a vested interest in cultivating talent and perpetuating a culture that facilitates the 
execution of our long-term objectives.

Other Information about the Company's Business 

We maintain an interest in evaluating the startup of possible new ventures and the acquisition of complementary 
businesses on an ongoing basis. In addition, our businesses develop new coverages or enter lines of business to meet the needs 
of insureds. 

Seasonal weather variations and other events affect the severity and frequency of losses sustained by the insurance and 

reinsurance businesses. Although the effect on our business of catastrophes such as tornadoes, hurricanes, hailstorms, wildfires, 
earthquakes and terrorist acts may be mitigated by reinsurance, they nevertheless can have a significant impact on the results of 
any one or more reporting periods.  

We have no customer that accounts for 10 percent or more of our consolidated revenues. 

Compliance by W. R. Berkley and its subsidiaries with federal, state and local provisions that have been enacted or 

adopted regulating the discharge of materials into the environment, or otherwise relating to protection of the environment, has 
not had a material effect upon our capital expenditures, earnings or competitive position.

ITEM  1A. RISK FACTORS

Our businesses face significant risks. If any of the events or circumstances described as risks below occur, our 
businesses, results of operations and/or financial condition could be materially and adversely affected. In addition to those 
described below, our businesses may also be adversely affected by risks and uncertainties not currently known to us or that we 
currently consider immaterial.

Risks Relating to Our Industry 

Our results may fluctuate as a result of many factors, including cyclical changes in the insurance and reinsurance 

industry.

27

The results of companies in the property casualty insurance industry historically have been subject to significant 
fluctuations and uncertainties in demand and pricing, causing cyclical changes in the insurance and reinsurance industry. The 
demand for insurance is influenced primarily by general economic conditions, while the supply of insurance is often directly 
related to available capacity or the perceived profitability of the business. At times, we have faced significant competition in our 
business as a result of existing insurers seeking to gain or maintain market share as well as new entrants and capital providers. 
Recently, premium rates have increased for most lines of business, while they have decreased in others, most notably workers' 
compensation and certain professional liability lines of business. The adequacy of premium rates is affected mainly by the 
severity and frequency of claims, which are influenced by many factors, including natural disasters, regulatory measures and 
court decisions that define and expand the extent of coverage, and the effects of economic and social inflation on the amount of 
claims payments due for injuries or losses. In addition, investment rates of return impact rate adequacy. These factors can have 
a significant impact on ultimate profitability because a property casualty insurance policy is priced before its costs are known as 
premiums usually are determined long before claims are reported. These factors could produce results that would have a 
negative impact on our results of operations and financial condition.

We face significant competitive pressures in our businesses, which can pressure premium rates in certain areas and 

could harm our ability to maintain or increase our profitability and premium volume in some parts of our business. 

We compete with a large number of other companies in our selected lines of business. We compete, and will continue to 

compete, with major U.S. and non-U.S. insurers and reinsurers, other regional companies, as well as mutual companies, 
specialty insurance companies, underwriting agencies, diversified financial services companies and insurtech companies. 
Competitiveness in our businesses is based on many factors, including premium charges, ratings assigned by independent rating 
agencies, commissions paid to producers, the perceived financial strength of the company, other terms and conditions offered, 
services provided, ease of doing business, speed of claims payment and reputation and experience in the lines to be written. 
Periods of insurance industry consolidation may further increase competition in some parts of our business and may cause our 
insurance subsidiaries to incur greater customer retention and acquisition expenses, affecting the profitability of existing and 
new business.

Some of our competitors, particularly in the reinsurance business, have greater financial and/or marketing resources than 
we do. These competitors within the reinsurance market include Swiss Re, Munich Re, Berkshire Hathaway and Partner Re. We 
expect that perceived financial strength, in particular, will become more important as customers seek high quality reinsurers. 

Recently, insurance prices have generally increased for most lines of business, excluding workers' compensation and 

certain professional liability lines of business. However, loss costs have also increased and the duration and magnitude of the 
improving pricing environment remains uncertain. Despite higher interest rates, current price levels for certain lines of business 
may remain below the prices required for us to achieve our long-term return objectives. We expect to continue to face strong 
competition in our business.

In recent years, various types of investors have increasingly sought to participate in the property and casualty insurance 
and reinsurance industries. Well-capitalized new entrants to the property and casualty insurance and reinsurance industries, or 
existing competitors that receive substantial infusions of capital or access to third-party capital, provide increasing competition, 
which may adversely impact our business and profitability. Further, an expanded supply of capital may lower costs for insurers 
and, as a consequence, those insurers may be able to price their products more competitively. In addition, technology 
companies or other third parties have created, and may in the future create, technology-enabled business models, processes, 
platforms or alternate distribution channels that may adversely impact our competitive position in some parts of our business.

This intense competition could cause the supply and/or demand for insurance or reinsurance to change, which affect our 

ability to price our products at attractive rates and retain existing business or write new products at adequate rates or on terms 
and conditions acceptable to us. If we are unable to retain existing business or write new business at adequate rates or on terms 
and conditions acceptable to us, our results of operations could be materially and adversely affected. 

Our actual claims losses may exceed our reserves for claims, which may require us to establish additional reserves. 

Our gross reserves for losses and loss expenses were approximately $18.7 billion as of December 31, 2023. Our loss 
reserves reflect our best estimates of the cost of settling claims and related expenses with respect to insured events that have 
occurred. 

Reserves do not represent an exact calculation of liability. Rather, reserves represent an estimate of what management 

expects the ultimate settlement and claims administration will cost for claims that have occurred, whether known or unknown. 
The major assumptions about anticipated loss emergence patterns are subject to unanticipated fluctuation. These estimates, 
which generally involve actuarial projections, are based on management's assessment of facts and circumstances then known, as 

28

well as estimates of future trends in claims severity and frequency, inflation, judicial theories of liability, reinsurance coverage, 
legislative changes and other factors, including the actions of third parties, which are beyond our control. 

The inherent uncertainties of estimating reserves are greater for certain types of liabilities, where long periods of time 

elapse before a definitive determination of liability is made and settlement is reached. In periods with increased economic 
volatility, it becomes more difficult to accurately estimate claim costs. It is especially difficult to estimate the impact of 
inflation on loss reserves given the current economic environment and related government actions. Both inflation overall and 
medical cost inflation, which has historically been greater than inflation overall, can have an adverse impact. In addition, 
although the Company has estimated the potential COVID-19 impact to its contingency and event cancellation, workers’ 
compensation, and other lines of business under a number of possible scenarios, there remains uncertainty around COVID-19's 
ultimate impact on the Company and its related reserves.

Reserve estimates are continually refined in an ongoing process as experience develops and further claims are reported 

and settled. Adjustments to reserves are reflected in the results of the periods in which such estimates are changed. Because 
setting reserves is inherently uncertain, we cannot assure that our current reserves will prove adequate in light of subsequent 
events. Should we need to increase our reserves, our pre-tax income for the reporting period would decrease by a corresponding 
amount. 

We discount our reserves for excess and assumed workers' compensation business because of the long period of time 

over which losses are paid. Discounting is intended to appropriately match losses and loss expenses to income earned on 
investment securities supporting liabilities. The expected loss and loss expense payout pattern subject to discounting is derived 
from our loss payout experience. Changes in the loss and loss expense payout pattern are recorded in the period they are 
determined. If the actual loss payout pattern is shorter than anticipated, the discount will be reduced and pre-tax income will 
decrease by a corresponding amount.

The effects of emerging claim and coverage issues on our business are uncertain.    

As industry practices and economic, legal, judicial, social, technological and other environmental conditions change, 
unexpected and unintended issues related to claim and coverage may emerge. These issues may adversely affect our business by 
either extending coverage beyond our underwriting intent or by increasing the number or size of claims. Examples of emerging 
claims and coverage issues include, but are not limited to: 

•

•

•

judicial expansion of policy coverage and a greater propensity to grant claimants more favorable amounts and the 
impact of new theories of liability;

plaintiffs targeting property and casualty insurers, including us, in purported class action litigation relating to claims-
handling and other practices;

social inflation trends, including higher and more frequent claims, more favorable judgments and legislated 
increases;

• medical developments that link health issues to particular causes, resulting in liability claims;

•

•

•

claims relating to unanticipated consequences of current or new technologies, including cyber security related risks; 

claims relating to potentially changing climate conditions; and

increased claims due to third party funding of litigation.

In some instances, these emerging issues may not become apparent for some time after we have issued the affected 
insurance policies. As a result, the full extent of liability under our insurance policies may not be known until many years after 
the policies are issued. 

In addition, the potential passage of new legislation designed to expand the right to sue, to remove limitations on 
recovery, to extend the statutes of limitations or otherwise to repeal or weaken tort reforms could have an adverse impact on our 
business. 

The effects of these and other unforeseen emerging claim and coverage issues are difficult to predict and could harm our 

business and materially and adversely affect our results of operations.

As a property casualty insurer, we face losses from natural and man-made catastrophes. 

Property casualty insurers are subject to claims arising out of catastrophes that may have a significant effect on their 
results of operations, liquidity and financial condition. Catastrophe losses have had a significant impact on our results. For 
example, catastrophe losses net of reinsurance recoveries, including COVID-19 related losses, were $195 million in 2023, $212 

29

million in 2022, and $202 million in 2021. Similarly, man-made catastrophes can also have a material impact on our financial 
results. Depending on market conditions and other factors, we may seek to increase our writing of property casualty insurance, 
and, accordingly, our exposure to catastrophic events would be increased.

Catastrophes can be caused by various events, including hurricanes, windstorms, earthquakes, tsunamis, hailstorms, 

explosions, severe winter weather and fires, pandemics, as well as terrorist and other man-made activities, including drilling, 
mining and other industrial accidents, the bankruptcy of a major company, war or other military actions, social unrest, 
cyber events or terrorist activities. The incidence and severity of catastrophes are inherently unpredictable, and longer-term 
natural catastrophe trends may be changing due to climate change causing increased variability and unpredictability. The extent 
of losses from a catastrophe is a function of both the total amount of insured exposure in the area affected by the event and the 
severity of the event. Some catastrophes are restricted to small geographic areas; however, hurricanes, earthquakes, tsunamis 
and other disasters may produce significant damage in large, heavily populated areas. Catastrophes can cause losses in a variety 
of our property and casualty lines, and most of our past catastrophe-related claims have resulted from severe storms. Seasonal 
weather variations or the impact of climate change may affect the severity and frequency of our losses. Insurance companies are 
not permitted to reserve for a catastrophe until it has occurred. It is therefore possible that a catastrophic event or multiple 
catastrophic events could produce significant losses and have a material adverse effect on our results of operations and financial 
condition.

The COVID-19 pandemic materially and adversely affected our results of operations, and, whether as a result of 
COVID-19's long-term effects, or new or emerging variants, or other potential pandemics, may further materially and 
adversely affect our results of operations, financial position and liquidity in the future.

The COVID-19 pandemic, including the related impact on the U.S. and global economies, materially and adversely 

affected our results of operations. The pandemic's impact on our business may continue, and potentially even worsen, whether 
as a result of COVID-19's long-term effects, or new or emerging variants, or even other potential pandemics. We cannot predict 
the magnitude or duration of such impact, particularly given the uncertainties associated with COVID-19 or other potential 
pandemics. The ultimate impact of COVID-19 or other potential pandemics on our results of operations, financial position and 
liquidity is not yet known, but includes the following: 

Adverse Legislative and Regulatory Action. Legislative and regulatory initiatives in response to COVID-19 or other 
similar future pandemics may adversely affect us, particularly in our workers’ compensation and property coverages businesses. 
For example, our business may be subject to, certain initiatives, including, but not limited to: legislative and regulatory action 
that seeks to retroactively mandate coverage for losses that our insurance policies would not otherwise cover and which were 
not priced to cover; legislative and regulatory action providing for shifting presumptions with respect to the burdens of proof 
for “essential” workers on workers’ compensation coverages and varying definitions of “essential” workers; actions prohibiting 
us from cancelling insurance policies in accordance with our policy terms or non-renewing policies at their natural expiration; 
and/or orders to provide premium refunds, grant extended grace periods for premium payments, and provide extended time to 
pay past due premiums. Any such action would likely increase both our underwriting losses and our expenses and any legal 
challenges to any such action could take years to resolve.

Claim Losses Related to COVID-19 May Exceed Reserves. As of December 31, 2023, we recorded approximately $384 
million for COVID-19-related losses. Our reserves do not represent an exact calculation of liability, but represent an estimate of 
what management expects the ultimate settlement and claims administration will cost for claims that have occurred, whether 
known or unknown. Accordingly, given the uncertainties still associated with COVID-19 and its impact, our reserves and the 
underlying estimated level of claim losses and costs arising from COVID-19 may materially change.

Claim Losses and Adjustment Expenses May Increase. As the effects of COVID-19 or future pandemics on industry 
practices and economic, legal, judicial, social and other environmental conditions occur, unexpected and unintended issues 
related to claims and coverages may emerge. These issues may adversely affect our business by extending coverage beyond our 
underwriting intent (including in the area of property coverages where physical damage requirements and communicable 
disease exclusions are currently being challenged) or by increasing the number and/or size of claims, each of which could 
adversely impact our results.

Reinsurance. We purchase reinsurance in order to transfer part of the risk that we have assumed by writing insurance 

policies to reinsurance companies in exchange for part of the premium we receive in connection with assuming such risk. 
Although reinsurance makes the reinsurer contractually liable to us to the extent the risk is transferred to the reinsurer, it does 
not relieve us of our liability to our policyholders. There may be uncertainty surrounding the availability of reinsurance 
coverage for losses related to COVID-19 or any future pandemics as our reinsurers may dispute the applicability of reinsurance 
to such losses (including the application of reinsurance reinstatements) and, as a result, our reinsurers may refuse to pay 
reinsurance recoverables related thereto or they may not pay them on a timely basis. On December 22, 2023, one of the 

30

Company’s subsidiaries filed a lawsuit against certain reinsurers to recover in excess of $90 million in respect of certain losses 
paid to its policyholders under certain event cancellation and related insurance policies. See, "Item 3. Legal Proceedings." In 
addition, we may be unable to renew our current reinsurance coverages or obtain appropriate new reinsurance covers with 
respect to certain exposures under our policies, including exposures related to COVID-19 or any future pandemics, and 
therefore our net exposures could increase, or if we are unwilling to bear such increase in net exposure, we may reduce our 
level of underwriting commitments.

Premium Volumes May Be Negatively Impacted. The demand for insurance is significantly influenced by general 

economic conditions. Consequently, any reduced economic activity relating to potential pandemics is likely to decrease demand 
for our insurance products and services and negatively impact our premium volumes (and, in certain cases, may result in return 
of premiums due to a decrease in exposures).

Investments. Disruptions in global financial markets due to future pandemics could cause us to incur unrealized and/or 

realized investment losses, including impairments in our fixed maturity portfolio and other investments. In addition, the 
economic uncertainty may result in a decline in interest rates, which may negatively impact our net investment income from 
future investment activity.

Operational Disruptions and Costs. Our operations could be disrupted if key members of our senior management or a 
significant percentage of our workforce or the workforce of our agents, brokers, suppliers or other third party service providers 
are unable to continue to work because of illness, government directives or otherwise. In addition, our agents, brokers, suppliers 
and other third party service providers, which we rely on for key aspects of our operations, are subject to similar risks and 
uncertainties, which may interfere with their ability to fulfill their respective commitments and responsibilities to us in a timely 
manner and in accordance with the agreed-upon terms. Any remote working policies we implement may result in disruptions to 
our business routines, heightened risk to cybersecurity attacks and data security incidents and a greater dependency on internet 
and telecommunication access and capabilities.

Changing climate conditions may alter the frequency and increase the severity of catastrophic events and thereby 

adversely affect our financial condition and results. 

In recent years, changing weather patterns and climatic conditions, such as global warming, appear to have contributed 

to the unpredictability, frequency and severity of natural disasters and created additional uncertainty as to future trends and 
exposures. There is a scientific consensus that global warming and other climate change are altering the frequency, severity and 
peril characteristics of catastrophic weather events, such as hurricanes, windstorms, floods and other natural disasters. Such 
changes make it more difficult for us to predict and model catastrophic events, reducing our ability to accurately price our 
exposure to such events and mitigate our risks. Any increase in the frequency or severity of natural disasters may adversely 
affect our financial condition and results.

We, as a primary insurer, may have significant exposure for terrorist acts. 

To the extent an act of terrorism, whether a domestic or foreign act, is certified by the Secretary of Treasury, we may 

be covered under the Terrorism Risk Insurance Program Reauthorization Act of 2019 (“TRIPRA”), for up to 80% of our 
covered losses for certain property/casualty lines of insurance. However, any such coverage would be subject to a mandatory 
deductible based on 20% of earned premium for the prior year for the covered lines of commercial property and casualty 
insurance. Based on our 2023 earned premiums, our aggregate deductible under TRIPRA during 2024 is approximately $1,464 
million. In addition, the coverage provided under TRIPRA does not apply to reinsurance that we write. To the extent that our 
reinsurers have excluded coverage for certain terrorist acts or have priced this coverage at rates that make purchasing such 
coverage economically infeasible, we may not have reinsurance protection and could be exposed to potential losses as a result 
of any acts of terrorism.  

We are exposed to, and may face adverse developments involving, mass tort claims.

We are exposed to, and may face adverse developments involving, mass tort claims such as those relating to exposure 

to potentially harmful products or substances. We face potential exposure to mass tort claims, including claims related to 
exposure to potentially harmful products or substances, such as lead paint, polyfluoroalkyl substances, talc and opioids. 
Establishing loss reserves for mass tort claims is subject to uncertainties because of many factors, including adverse changes to 
the tort environment (e.g., increased and more aggressive attorney involvement in insurance claims, increased litigation, 
expanded theories of liability, higher jury awards, lawsuit abuse and third-party litigation finance, among others); evolving 
judicial interpretations, including application of various theories of joint and several liabilities; disputes concerning medical 
causation with respect to certain diseases; geographical concentration of the lawsuits asserting the claims; and the potential for a 
large rise in the total number of claims without underlying epidemiological developments suggesting an increase in disease 
rates. Because of the uncertainties set forth above, additional liabilities may arise for amounts in excess of the current loss 

31

reserves. In addition, our estimate of loss reserves may change. These additional liabilities or increases in estimates, or a range 
of either, could vary significantly from period to period and could materially and adversely affect our results of operations and/
or our financial position. 

We are subject to extensive governmental regulation, which increases our costs and could restrict the conduct of 

our business. 

We are subject to extensive governmental regulation and supervision in both the United States and foreign 

jurisdictions. Most insurance regulations are designed to protect the interests of policyholders rather than stockholders and other 
investors. This system of regulation, generally administered in the United States by a department of insurance in each state in 
which we do business, relates to, among other things:

•

•

•

•

•

•

•

•

•

standards of solvency, including risk-based capital measurements;

restrictions on the nature, quality and concentration of investments;

limitations  on the amount of dividends, tax distributions, intercompany loans and other payments that can be made 
without prior regulatory approval;

requirements pertaining to certain methods of accounting;

evaluating enterprise risk to an insurer;

privacy, data protection, and cybersecurity;

rate and form regulation pertaining to certain of our insurance businesses; 

potential assessments for the provision of funds necessary for the settlement of covered claims under certain policies 
provided by impaired, insolvent or failed insurance companies; and

involvement in the payment or adjudication of catastrophe or other claims beyond the terms of the policies.

State insurance departments conduct periodic examinations of the affairs of insurance companies and require the filing 

of annual and other reports relating to the financial condition of insurance companies, holding company issues and other 
matters. Our Insurance business internationally is also generally subject to a similar regulatory scheme in each of the 
jurisdictions where we conduct operations outside the United States.

Federal financial services modernization legislation and legislative and regulatory initiatives taken or which may be 
taken in response to conditions in the financial markets, global insurance supervision and other factors may lead to additional 
federal regulation of the insurance industry in the coming years.

The Dodd-Frank Act effected sweeping changes to financial services regulation in the United States. The Dodd-Frank 

Act established the FSOC, which is authorized to recommend that certain systemically significant non-bank financial 
companies, including insurance companies, be regulated by the Board of Governors of the Federal Reserve. The Dodd-Frank 
Act also established a FIO which is authorized to study, monitor and report to Congress on the U.S. insurance industry and the 
significance of global reinsurance to the U.S. insurance market. The FIO also can recommend that the FSOC designate an 
insurer as an entity posing risks to the United States financial stability in the event of the insurer's material financial distress or 
failure. Our business could be affected by changes, whether as a result of potential changes to the Dodd-Frank Act, to the 
U.S. system of insurance regulation or our designation or the designation of insurers or reinsurers with which we do business as 
systemically significant non-bank financial companies.

The topic of climate risk has come under increased scrutiny by the NAIC and insurance regulators. For instance, in 

New York, the NYDFS’s circular letter, which applies to our insurance subsidiaries licensed in New York, states that regulated 
insurers are expected to integrate financial risks related to climate change into their governance frameworks, risk management 
processes, business strategies and scenario analysis, and develop their approach to climate-related financial disclosure. The 
NYDFS also amended the regulation governing enterprise risk management, which applies to our insurance subsidiaries 
licensed in New York, that requires an insurance group's enterprise risk management function to address certain additional 
risks, including climate change risk. In addition, the FIO is assessing how the insurance sector may help mitigate climate- 
related risks and achieve national climate-related goals, and it released a report in June 2023 urging insurance regulators to 
adopt climate-related risk monitoring guidance. These measures may subject us to increased oversight at the state and federal 
level.

State regulation is the primary form of regulation of insurance and reinsurance in the United States, although Congress 

has considered various proposals regarding federal regulation of insurance, in addition to the changes brought about by the 

32

Dodd-Frank Act, such as proposals for the creation of an optional federal charter for insurance companies. We may be subject 
to potentially increased federal oversight as a financial institution. In addition, the current U.S. administration and the volatile 
political environment (including, in particular, the upcoming U.S. presidential election in November 2024) increases the chance 
of other federal legislative and regulatory changes that could affect us in ways we cannot predict.

With respect to international measures, Solvency II, the EU regime concerning the capital adequacy, risk management 

and regulatory reporting for insurers and reinsurers may affect our insurance businesses. As described in “International 
Regulation” above, the EU is performing a review of Solvency II and various regulatory reforms are expected to be introduced 
during 2024, which EU member states will implement in their domestic regulation. In addition, despite the waiver of the 
Solvency II group capital requirements we received, Solvency II may have the effect of increasing the capital requirements of 
our EU domiciled insurers. Additionally, our capital requirements and compliance requirements may be adversely affected if 
the European Commission does not deem the insurance regulatory regimes of the jurisdictions outside the EU in which we have 
insurance or reinsurance companies domiciled to be “equivalent” to Solvency II.

Similar considerations apply to our U.K. subsidiaries, which are now subject to a separate U.K. prudential regime, 

which  is broadly identical to Solvency II. However, the two regimes, and their respective requirements, are diverging due to 
both the EU’s review of Solvency II described above and the recently adopted reforms to the U.K.’s domestic prudential regime 
(please see “International Regulation” above for more information). We therefore may be required to utilize additional 
resources to ensure compliance with the different rules in each regime.

If our compliance with Solvency II, the U.K.’s prudential regime or any other regulatory regime is challenged, we may 
be subject to monetary or other penalties. In addition, in order to ensure compliance with applicable regulatory requirements or 
as a result of any investigation, including remediation efforts, we could be required to incur significant expenses and undertake 
additional work, which in turn may divert resources from our business. 

We may be unable to maintain all required licenses and approvals and our business may not fully comply with the 

wide variety of applicable laws and regulations or the relevant authority's interpretation of the laws and regulations. Also, some 
regulatory authorities have relatively broad discretion to grant, renew or revoke licenses and approvals. If we do not have the 
requisite licenses and approvals or do not comply with applicable regulatory requirements, the insurance regulatory authorities 
could preclude or temporarily suspend us from carrying on some or all of our activities or monetarily penalize us. Also, changes 
in the level of regulation of the insurance industry, whether federal, state or foreign, or changes in laws or regulations 
themselves or interpretations thereof by regulatory authorities, may further restrict the conduct of our business. 

Risks Relating to Our Business

Our expanding international operations expose us to increased investment, political, legal/regulatory, and economic 

risks, including foreign currency and credit risk.

Our expanding international operations in the United Kingdom, Continental Europe, South America, Canada, Mexico, 

Scandinavia, the Asia-Pacific region, South Africa and Australia expose us to increased investment, political, legal/regulatory, 
and economic risks, including foreign currency and credit risk. Changes in the value of the U.S. dollar relative to other 
currencies have had and could in the future have an adverse effect on our results of operations and financial condition. 

Our investments in non-U.S.-denominated assets are subject to fluctuations in non-U.S. securities and currency markets, 

and those markets can be volatile. Non-U.S. currency fluctuations also affect the value of any dividends paid by our non-
U.S. subsidiaries to their parent companies in the U.S.

We face additional risks as a result of our international operations  which could have an adverse effect on our results of 
operations and financial condition  including: burdens and costs of compliance with a variety of foreign laws and regulations 
and the associated risk and costs of non-compliance; exposure to undeveloped or evolving legal systems, which may result in 
unpredictable or inconsistent application of laws and regulations; exposure to commercial, political, legal or regulatory 
corruption; political, economic or other instability in countries in which we conduct business, including possible terrorist acts; 
the imposition of tariffs, trade barriers or other protectionist laws or business practices that favor local competition, increased 
costs and adverse effects on our business; changes to visa or immigration policies; diminished ability to enforce our contractual 
rights; potential increased risk of data breaches; differences in cultural environments; sociopolitical instability; social, political 
or economic instability resulting from climate change; changes in regulatory requirements, including changes in regulatory 
treatment of certain products or services; exposure to local economic conditions and its impact on our clients’ performance and 
creditworthiness; and restrictions on the repatriation of non-U.S. investments and earnings.

33

Our U.K. business could be specifically adversely impacted by the imposition of trade barriers between the EU and the 

U.K. following Brexit, which has already reduced the level of trade between the two markets and the U.K.’s overall trade 
exports, thereby negatively affecting the attractiveness of the U.K. market.

We may be unable to attract and retain key personnel and qualified employees.

We depend on our ability to attract and retain key personnel, including our President and CEO, Executive Chairman, 

senior executive officers, presidents of our businesses, experienced underwriters and other skilled employees who are 
knowledgeable about our business. If the quality of our underwriting team and other personnel decreases, we may be unable to 
maintain our current competitive position in the specialized markets in which we operate, and be unable to expand our 
operations into new products and markets.

We cannot guarantee that our reinsurers will pay in a timely fashion, if at all, and, as a result, we could experience 

losses. 

We purchase reinsurance by transferring part of the risk that we have assumed, known as ceding, to a reinsurance 
company in exchange for part of the premium we receive in connection with the risk. Although reinsurance makes the reinsurer 
contractually liable to us to the extent the risk is transferred or ceded to the reinsurer, it does not relieve us, the reinsured, of our 
liability to our policyholders. Our reinsurers may not pay the reinsurance recoverables that they owe to us or they may not pay 
such recoverables on a timely basis. This failure to pay or failure to pay on a timely basis may be due to factors such as whether 
reinsurers, their affiliates or certain indemnitors have the financial capacity and willingness to make payments under the terms 
of a reinsurance treaty or contract. Accordingly, we bear credit risk with respect to our reinsurers, and if our reinsurers fail to 
pay us, our financial results would be adversely affected. Underwriting results and investment returns of some of our reinsurers 
may affect their future ability to pay claims. As of December 31, 2023, the amount due from our reinsurers was approximately 
$3,535 million, including amounts due from state funds and industry pools where it was intended that we would bear no risk. 
Certain of these amounts are secured by letters of credit or by funds held in trust on our behalf.

We are subject to credit risk relating to our policyholders, independent agents and brokers.

In addition to exposure to credit risk related to our reinsurance recoverables and investment portfolio, we are exposed to 
credit risk in several other areas of our business, including credit risk relating to policyholders, independent agents and brokers. 
For example our policyholders, independent agents or brokers may not pay a part of or the full amount of premiums owed to us 
or our brokers or other third party claim administrators may not deliver amounts owed on claims under our insurance and 
reinsurance contracts for which we have provided funds.

As credit risk is generally a function of the economy, we face a greater credit risk in an economic downturn. While we 
attempt to manage credit risks through underwriting guidelines, collateral requirements and other oversight mechanisms, our 
efforts may not be successful. For example, to reduce such credit risk, we require certain third parties to post collateral for some 
or all of their obligations to us. In cases where we receive pledged securities and the applicable counterparty is unable to honor 
its obligations, we may be exposed to credit risk on the securities pledged and/or the risk that our access to that collateral may 
be stayed as a result of bankruptcy. In cases where we receive letters of credit from banks as collateral and one of our 
counterparties is unable to honor its obligations, we are exposed to the credit risk of the banks that issued the letters of credit.

We are rated by A.M. Best, Standard & Poor's, Moody's, and Fitch, and a decline in these ratings could affect our 

standing in the insurance industry and cause our sales and earnings to decrease.

Ratings have become an increasingly important factor in establishing the competitive position of insurance companies. 
Certain of our insurance company subsidiaries are rated by A.M. Best, Standard & Poor's, Moody's and Fitch. Our ratings are 
subject to periodic review, and we cannot assure you that we will be able to retain our current or any future ratings, especially 
given that rating agencies may change their criteria or increase capital requirements for various rating levels. For instance, 
Standard & Poor's has recently proposed changes to its rating model which could impact our rating depending on final changes 
that are implemented. 

If our ratings are reduced from their current levels by A.M. Best, Standard & Poor's, Moody's or Fitch, our competitive 

position in the insurance industry could suffer and it would be more difficult for us to market our products. A ratings 
downgrade could also adversely limit our access to capital markets, which may increase the cost of debt. A significant 
downgrade could result in a substantial loss of business as policyholders move to other companies with higher financial strength 
ratings.

If market conditions cause reinsurance to be more costly or unavailable, we may be required to bear increased risks 

or reduce the level of our underwriting commitments.

34

As part of our overall risk and capacity management strategy, we purchase reinsurance for certain amounts of risk 

underwritten by our insurance company subsidiaries, especially catastrophe risks and those risks with relatively high policy 
limits. We also purchase reinsurance on risks underwritten by others which we reinsure. Market conditions beyond our control 
determine the availability and cost of the reinsurance protection we seek to purchase, which may affect the level of our business 
and profitability. Our reinsurance contracts are generally subject to annual renewal, and we may be unable to maintain our 
current reinsurance contracts or to obtain other reinsurance contracts in adequate amounts and at favorable rates. In addition, we 
may be unable to obtain reinsurance on terms acceptable to us relating to certain lines of business that we intend to begin 
writing. If we are unable to renew our expiring contracts or to obtain new reinsurance contracts, either our net exposures would 
increase or, if we are unwilling to bear an increase in net exposures, we would have to reduce the level of our underwriting 
commitments, especially catastrophe exposed risks.

Depending on conditions in the financial markets and the general economy, we may be unable to raise debt or equity 

capital if needed.

If conditions in the financial markets and the general economy are unfavorable, which may result from disruptions, 
uncertainty or volatility in the capital and credit markets, we may be unable to access debt or equity capital on acceptable terms 
if needed, which could have a negative impact on our ability to invest in our insurance company subsidiaries and/or to take 
advantage of opportunities to expand our business, such as the creation of new ventures and possible acquisitions, and inhibit 
our ability to refinance our existing indebtedness if we desire to do so, on terms acceptable to us. 

We may not find suitable new insurance ventures and acquisition candidates and even if we do, we may not 

successfully invest in such ventures or successfully integrate any such acquired companies.

As part of our present strategy, we continue to evaluate the possible start-up of complementary businesses and 
acquisition transactions on an ongoing basis, and at any given time we may be engaged in discussions with respect to possible 
new ventures and acquisitions. We cannot assure you that we will be able to identify suitable insurance ventures or acquisition 
targets, that such transactions will be financed and completed on acceptable terms or that our future start-up ventures or 
acquisitions will be successful. Our financial results could be adversely affected by acquired businesses not performing as 
projected, unforeseen liabilities, routine and unanticipated transaction-related charges, diversion of management time and 
resources to acquisition integration challenges or growth strategies, loss of key employees, challenges in integrating 
information technology systems of acquired companies with our own, amortization of expenses related to intangibles, charges 
for impairment of long-term assets or goodwill and indemnification. The process of investing in new ventures or integrating any 
companies we do acquire may have a material adverse effect on our results of operations and financial condition.

If our information technology, telecommunications or other computer systems become unavailable or unreliable, our 

ability to conduct our business could be negatively or severely impacted.    

Our business is highly dependent upon our employees' ability to perform necessary business functions in an efficient and 
uninterrupted fashion. A shut-down of, or inability to access, one or more of our facilities, a power outage or a failure of one or 
more of our information technology, telecommunications or other computer systems could significantly impair our employees' 
ability to perform such functions on a timely basis. In the event of a disaster such as a natural catastrophe, terrorist attack or 
industrial accident, physical or electronic security breaches, such as breaches by computer hackers, the infection of our systems 
by a malicious computer virus, denial of service attack, or other cybersecurity incident, our systems could be inaccessible for an 
extended period of time. In addition, because our information technology and telecommunications systems interface with and 
depend on third-party systems, we could experience service denials or failures of controls if demand for our service exceeds 
capacity or a third-party system fails or experiences an interruption. If our business continuity plans or system security does not 
sufficiently address such a business interruption, system failure or service denial, our ability to write and process new and 
renewal business, provide customer service, pay claims in a timely manner or perform other necessary business functions could 
be significantly impaired and our business could be harmed.

Failure to maintain the security of information technology systems and confidential data may expose us to liability.

Although we have taken steps intended to protect our data and information technology systems and mitigate the risk of 

harm caused by cybersecurity incidents or breaches, no safeguards are perfect and any failure of these safeguards could cause a 
substantial disruption of our business operations, which could result in service interruptions, data security compromises, 
regulatory action, and other similar operational and legal issues, as well as substantial remediation and other costs. Our 
operations rely on the secure processing, storage and transmission of confidential and other sensitive information, including 
personal information, in our computer systems and networks. Cybersecurity breaches, including physical or electronic break-
ins, computer viruses, malware, attacks by hackers, ransomware attacks, phishing attacks, supply chain attacks, breaches due to 
employee error or misconduct and other similar breaches can create system disruptions, shutdowns or unauthorized access to, or 
disclosure of, information maintained in our information technology systems and in the information technology systems of our 

35

vendors and other third parties. We have in the past experienced cybersecurity breaches of our information technology systems 
as well as the information technology systems of our vendors and other third parties, but, to our knowledge, we have not 
experienced any material cybersecurity breaches. We expect cybersecurity breaches to continue to occur in the future and we 
are constantly managing efforts to infiltrate and compromise our systems and data. Our electronic transmission of personal, 
confidential and proprietary information to third parties with whom we have business relationships and our outsourcing of 
certain technology and business process functions to third parties may expose us to enhanced risk related to data security. While 
we have implemented secure data transmission capabilities with these third-party vendors and others with whom we do 
business, such capabilities may not function as intended and our vendors and third parties could still suffer data breaches that 
could result in the exposure of sensitive data and the infiltration of our computer systems. Our failure to effectively protect 
sensitive personal and/or proprietary information, whether owing to breaches of our own systems or those of our vendors and 
other third parties, could result in significant monetary and reputational damages, material adverse effects to our financial 
condition, costly litigation, or other regulatory enforcement actions. These increased risks, and expanding regulatory 
requirements regarding data security, including required compliance with applicable privacy and data protection laws (e.g., the 
GDPR, CCPA, and other state-specific privacy statutes and regulations, could expose us to data loss, monetary and reputational 
damages and significant increases in compliance costs. As a result, our ability to conduct our business could be materially and 
adversely affected. 

We could be adversely affected if our controls to ensure compliance with guidelines, policies and legal and regulatory 

standards are not effective.    

Our business is highly dependent on our ability to engage on a daily basis in a large number of insurance underwriting, 

claim processing and investment activities, many of which are highly complex. These activities often are subject to internal 
guidelines and policies, as well as legal and regulatory standards, including those related to privacy and data security, anti-
corruption, anti-bribery and global finance and insurance matters. Our continued expansion into new international markets has 
brought about additional requirements. A control system, no matter how well designed and operated, can provide only 
reasonable assurance that the control system's objectives will be met. If our controls are not effective, it could lead to financial 
loss, unanticipated risk exposure (including underwriting, credit and investment risk), regulatory scrutiny, and/or damage to our 
reputation.

We could be adversely affected by changes in U.S. Federal income tax laws. 

Tax legislation commonly referred to as the Tax Cuts and Jobs Act, which was signed into law on December 22, 2017, 

fundamentally overhauled the U.S. tax system by, among other significant changes, reducing the U.S. corporate income tax rate 
to 21%. In the context of the taxation of U.S. property/casualty insurance companies such as the Company, the Act also 
modified the loss reserve discounting rules and the proration rules that apply to reduce reserve deductions to reflect the lower 
corporate income tax rate. It is possible that other legislation could be introduced and enacted by the current Congress or future 
Congresses that could have an adverse impact on us. New regulations or pronouncements interpreting or clarifying provisions 
of the Act may be forthcoming. We cannot predict if, when or in what form such regulations or pronouncements may be 
provided, whether such guidance will have a retroactive effect or their potential impact on us. 

Limitations in risk management and loss limitation methods may adversely impact our business.

We seek to effectively manage risk and limit our losses in a variety of ways including through effective underwriting, 
tailoring policy terms, and the use of reinsurance. However, there are certain limitations in these and similar tactics and as a 
result, loss levels may be higher than modeled or otherwise expected, which could have a material adverse effect on our 
business.

Increased scrutiny on social responsibility and the efforts we take to implement related measures, or the failure to 

take such measures, may adversely impact our business.

There is increased scrutiny from regulators and investors on the measures companies take to be socially responsible. 

Although we have made efforts to be responsible in this manner, for example through our commitment to fostering a unifying 
culture and encouraging innovation across our operating units, these types of pressures may nonetheless present challenges and 
have an adverse impact on our business. In addition, we may be subject to negative publicity based on a failure or perceived 
failure to achieve various social responsibility initiatives and goals relating to diversity, equity and inclusion, and commitment 
to long-term sustainability we may announce from time to time, or based on an actual or perceived increase in related risks as a 
result of our or our industry’s business activities.

Risks Relating to Our Investments 

A significant amount of our assets is invested in fixed maturity securities and is subject to market fluctuations. 

36

Our investment portfolio consists substantially of fixed maturity securities. As of December 31, 2023, our investment in 

fixed maturity securities was approximately $20.2 billion, or 75.8% of our total investment portfolio including cash and cash 
equivalents. As of that date, our portfolio of fixed maturity securities consisted of the following types of securities: 
U.S. Government securities (8.4%); state and municipal securities (13.3%); corporate securities (37.9%); asset-backed 
securities (20.8%); mortgage-backed securities (11.3%) and foreign government (8.3%). 

The fair value of these assets and the investment income from these assets fluctuate depending on general economic and 
market conditions. The fair value of fixed maturity securities generally decreases as interest rates rise. If a significant increase 
in interest rates were to occur, the fair value of our fixed maturity securities would be negatively impacted, while investment 
income earned from future investments in fixed maturity securities would be higher. Conversely, if interest rates decline, the 
fair value of our fixed maturity securities would be positively impacted, and investment income earned from future investments 
in fixed maturity securities will be lower. Some fixed maturity securities, such as mortgage-backed and other asset-backed 
securities, also carry prepayment risk as a result of interest rate fluctuations. In low interest rate environments, we may not be 
able to successfully reinvest the proceeds from maturing securities at yields commensurate with our target performance goals.

The value of investments in fixed maturity securities is subject to impairment as a result of deterioration in the credit 

worthiness of the issuer, default by the issuer (including states and municipalities) in the performance of its obligations in 
respect of the securities and/or increases in market interest rates. To a large degree, the credit risk we face is a function of the 
economy; accordingly, we face a greater risk in an economic downturn or recession. During periods of market disruption, it 
may be difficult to value certain of our securities, particularly if trading becomes less frequent and/or market data becomes less 
observable. There may be certain asset classes that were in active markets with significant observable data that become illiquid 
due to the then current financial environment. In such cases, more securities may require additional subjectivity and 
management judgment.

Although the historical rates of default on state and municipal securities have been relatively low, our state and 
municipal fixed maturity securities could be subject to a higher risk of default or impairment due to declining municipal tax 
bases and revenue. Many states and municipalities operate under deficits or projected deficits, the severity and duration of 
which could have an adverse impact on both the valuation of our state and municipal fixed maturity securities and the issuer's 
ability to perform its obligations thereunder. Additionally, our investments are subject to losses as a result of a general decrease 
in commercial and economic activity for an industry sector in which we invest, as well as risks inherent in particular securities.

Although we attempt to manage these risks through the use of investment guidelines and other oversight mechanisms and 

by diversifying our portfolio and emphasizing preservation of principal, our efforts may not be successful. Impairments, 
defaults and/or rate increases could reduce our net investment income or realized and unrealized investment gains or result in 
investment losses. Investment returns are currently, and will likely continue to be, impacted by economic uncertainty, more 
generally, and the shape of the yield curve. As a result, our exposure to the risks described above could materially and adversely 
affect our results of operations, liquidity and financial condition.

We have invested a portion of our assets in equity securities, merger arbitrage securities, investment funds, private 

equity, loans and real estate related assets, which are subject to significant volatility and may decline in value.

We invest a portion of our investment portfolio in equity securities, merger arbitrage securities, investment funds, private 

equity, loans and real estate related assets. At December 31, 2023, our investment in these assets was approximately $5.1 
billion, or 19.1%, of our investment portfolio, including cash and cash equivalents.

Merger and arbitrage trading securities were $0.9 billion, or 3.5% of our investment portfolio, including cash and cash 

equivalents at December 31, 2023. Merger arbitrage involves investing in the securities of publicly held companies that are the 
targets in announced tender offers and mergers. Merger arbitrage differs from other types of investments in its focus on 
transactions and events believed likely to bring about a change in value over a relatively short time period, usually four months 
or less. Our merger arbitrage positions are exposed to the risk associated with the completion of announced deals, which are 
subject to regulatory as well as political and other risks.

Real estate related investments, including directly owned, investment funds and loans receivable, were $1.7 billion, or  

6.2% of our investment portfolio, including cash and cash equivalents, at December 31, 2023. We also invest in real estate, 
financial services, energy, transportation and other investment funds. The values of these investments are subject to fluctuation 
based on changes in the economy and interest rates in general and the related asset valuations in particular. In addition, our 
investments in real estate related assets and other alternative investments are less liquid than our other investments.

These investments are subject to significant volatility as a result of the conditions in the financial and commodity 

markets and the global economy.

Risks Relating to Limitations on Dividends from Subsidiaries and Anti-Takeover Provisions

We are an insurance holding company and, therefore, may not be able to receive dividends in needed amounts.

As an insurance holding company, our principal assets are the shares of capital stock of our insurance company 
subsidiaries. We have to rely on dividends from our insurance company subsidiaries to meet our obligations for paying 
principal and interest on outstanding debt obligations, paying dividends to stockholders and repurchasing our shares and paying 
corporate expenses. The payment of dividends by our insurance company subsidiaries is subject to regulatory restrictions and 
competitive pressures on maintaining financial strength ratings and will depend on the surplus and future earnings of these 
subsidiaries. During 2024, the maximum amount of dividends that can be paid without regulatory approval is approximately 
$1.2 billion. Future regulatory actions could further restrict our insurance subsidiaries’ ability to pay us dividends. As a result, 
in the future we may not be able to receive dividends from these subsidiaries at times and in amounts necessary to meet our 
obligations, pay dividends or repurchase shares.

Laws and regulations of the jurisdictions in which we conduct business could delay, deter or prevent an attempt to 
acquire control of us that stockholders might consider to be desirable, and may restrict a stockholder's ability to purchase 
our common stock. 

Generally, United States insurance holding company laws require that, before a person can acquire control of an 
insurance company, prior written approval must be obtained from the insurance regulatory authority in the state in which that 
insurance company is domiciled. Pursuant to applicable laws and regulations, “control” over an insurer is generally presumed to 
exist if any person, directly or indirectly, owns, controls, holds the power to vote, or holds proxies representing 10% or more of 
the voting securities of that insurer or any parent company of such insurer. Indirect ownership includes ownership of the shares 
of our common stock. Thus, the insurance regulatory authorities of the states in which our insurance subsidiaries are domiciled 
are likely to apply these restrictions on acquisition of control to any proposed acquisition of our common stock. Some states 
require a person seeking to acquire control of an insurer licensed but not domiciled in that state to make a filing prior to 
completing an acquisition if the acquirer and its affiliates, on the one hand, and the target insurer and its affiliates, on the other 
hand, have specified market shares in the same lines of insurance in that state. Additionally, many foreign jurisdictions where 
we conduct business impose similar restrictions and requirements. 

These provisions can also lead to the imposition of conditions on an acquisition that could delay or prevent its 

consummation. These laws may discourage potential acquisition proposals and may delay, deter or prevent a change in control 
of us through transactions, and in particular unsolicited transactions, that some or all of our stockholders might consider to be 
desirable. 

Certain provisions in our organizational documents may have the effect of hindering, delaying or preventing third 

party takeovers and thus may prevent our stockholders from receiving premium prices for their shares in an unsolicited 
takeover or make it more difficult for third parties to replace our current management.

Provisions of our Restated Certificate of Incorporation and By-Laws, as well as state insurance statutes, may hinder, 
delay or prevent unsolicited acquisitions or changes of our control. These provisions may also have the effect of making it more 
difficult for third parties to cause the replacement of our current management without the concurrence of our Board of 
Directors. 

These provisions include:
•

our classified board of directors and the ability of our board to increase its size and to appoint directors to fill newly 
created directorships;

•

•

the requirement that the holders of 80% of our shares must approve mergers and other transactions between us and 
the holder of 5% or more of our shares, unless the transaction was approved by our board of directors prior to such 
holder's acquisition of 5% of our shares; and

the need for advance notice in order to raise business or make nominations at stockholders' meetings.

These provisions may discourage potential acquisition proposals and may delay, deter or prevent a change in control of 

us through transactions, and in particular unsolicited transactions, that some or all of our stockholders might consider to be 
desirable.

ITEM 1B. UNRESOLVED STAFF COMMENTS

There are no unresolved written comments that were received from the SEC staff 180 days or more before the end of our 

fiscal year relating to our periodic or current reports under the Securities Exchange Act of 1934.

ITEM 1C. CYBERSECURITY

Cybersecurity Strategy and Risk Management Program

The Company has a documented information security program (the Program) to identify, assess, monitor and manage 

potential cybersecurity threats and incidents.  The Program is designed to protect the confidentiality, integrity and availability of 
our information systems and assets that store, process, or transmit information.  The Program is modeled on the global standard 
for risk assessment, International Organization for Standardization 27001, and is guided by the six domains of cybersecurity 
established by the National Institute of Standards and Technology Cybersecurity Framework (i.e., govern, identify, protect, 
detect, respond, and recovery).  The Program seeks to adhere to applicable U.S. and international laws and regulations, 
including New York State’s cybersecurity regulation applicable to financial services institutions authorized by the New York 
State Department of Financial Services.

The Program’s security and risk policies and standards, implemented by either the Company or third party assessors or 

consultants, include: 

–

–

–

–

–

information security management tools, such as firewalls, intrusion prevention and detection systems, anti-malware 
functionality, and access privilege controls;

vulnerability management, including penetration and control testing and vulnerability scans of information systems;

incident monitoring, breach notification and escalation, including disaster recovery and incident response plans and 
resources;

risk based assessment of third party service providers; and

annual cybersecurity awareness training for employees and contractors.

The Company has not identified any cybersecurity incidents that have materially affected or are reasonably likely to 

materially affect the Company, including its business strategy, results of operations, or financial condition, for the period 
covered by this annual report.  For a discussion regarding risks associated with cybersecurity threats, see Risk Factors – Risks 
Relating to Our Business – “If our information technology, telecommunications or other computer systems become unavailable 
or unreliable, our ability to conduct our business could be negatively or severely impacted” and “Failure to maintain the 
security of information technology systems and confidential data may expose us to liability.”

Board Oversight, Governance and Risk Management

The entire Board of Directors has oversight of risks from cybersecurity threats and receives periodic updates on such 

risks from the Company’s management, including from the Company’s President and CEO and its Vice President, Chief 
Information Security Officer (CISO).  

Our CISO is principally responsible for assessing and managing all aspects of the Program, including the Company’s 

Regional Information Security Officers (RISOs), third-party consultants, development of industry trends and control testing and 
tracking by risk level.  Our CISO meets periodically with senior executives, including the Company’s President and Chief 
Executive Officer, to discuss the Company’s cybersecurity strategy, and its monitoring, prevention, detection, mitigation, and 
remediation of cybersecurity risks.  Regular reporting on the Program is also provided to the Company’s Enterprise Risk 
Management Committee, which is comprised of the President and CEO, Senior Vice President – Enterprise Risk Management, 
Executive Vice President – Investments, Executive Vice President – Chief Financial Officer, Executive Vice President – 
Secretary, and the Of Counsel and Assistant Secretary.  Collectively, the CISO and RISOs, along with their teams, in 
collaboration with the technology and business owners, implement the Program.  Legal, Compliance, and Internal Audit 
functions also assess the Program’s adherence to regulatory requirements and internal controls.  

In the event of a potentially material cybersecurity incident, the Company’s incident response plans establish escalation 

protocols for relevant IT leaders and functional leaders within Enterprise Risk Management, Legal, Compliance and Internal 
Audit to engage management as appropriate.  

Our CISO has over 25 years of information security experience and is licensed as a Certified Information Systems 

Security Professional.

ITEM 2. PROPERTIES

W. R. Berkley and its subsidiaries own or lease office buildings or office space suitable to conduct their operations. At 
December 31, 2023, the Company had aggregate office space of 4,333,225 square feet, of which 1,042,156 were owned and 
3,291,069 were leased. 

Rental expense for the Company's operations was approximately $44,256,000, $43,383,000 and $44,051,000 for 2023, 

2022 and 2021, respectively. Future minimum lease payments, without provision for sublease income, are $50,222,000 in 2024, 
$41,249,000 in 2025 and $166,192,000 thereafter.

ITEM 3. LEGAL PROCEEDINGS

The Company's subsidiaries are subject to disputes, including litigation and arbitration, arising in the ordinary course of 

their insurance and reinsurance businesses. The Company's estimates of the costs of settling such matters are reflected in its 
aggregate reserves for losses and loss expenses, and the Company does not believe that the ultimate outcome of such matters 
will have a material adverse effect on its financial condition or results of operations.

On December 22, 2023, one of the Company’s subsidiaries filed a lawsuit against certain reinsurers to recover in excess 

of $90 million in respect of certain losses paid to its policyholders under certain event cancellation and related insurance 
policies. The Company believes its claims against the reinsurers are meritorious and expects a positive resolution to its lawsuit. 
While an adverse outcome is possible, the Company believes that the outcome, in any case, will not be material to the 
Company’s financial condition.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF 
OPERATIONS

Overview

W. R. Berkley Corporation is an insurance holding company that is among the largest commercial lines writers in the 

United States and operates worldwide in two segments of the property and casualty business: Insurance and Reinsurance & 
Monoline Excess. Our decentralized structure provides us with the flexibility to respond quickly and efficiently to local or 
specific market conditions and to pursue specialty business niches. It also allows us to be closer to our customers in order to 
better understand their individual needs and risk characteristics. While providing our business units with certain operating 
autonomy, our structure allows us to capitalize on the benefits of economies of scale through centralized capital, investment, 
reinsurance, enterprise risk management, and actuarial, financial and corporate compliance support. The Company’s primary 
sources of revenues and earnings are its insurance operations and its investments.

An important part of our strategy is to form new businesses to capitalize on various opportunities. Over the years, the 

Company has formed numerous businesses that are focused on important parts of the economy in the U.S., including healthcare, 
cyber security, energy and agriculture, and on growing international markets, including the Asia-Pacific region, South America 
and Mexico.

The profitability of the Company’s insurance business is affected primarily by the adequacy of premium rates. The 

ultimate adequacy of premium rates is not known with certainty at the time an insurance policy is issued because premiums are 
determined before claims are reported. The ultimate adequacy of premium rates is affected mainly by the severity and 
frequency of claims, which are influenced by many factors, including natural and other disasters, regulatory measures and court 
decisions that define and change the extent of coverage and the effects of economic or social inflation on the amount of 
compensation for injuries or losses. General insurance prices are also influenced by available insurance capacity, i.e., the level 
of capital employed in the industry, and the industry’s willingness to deploy that capital.

The Company’s profitability is also affected by its investment income and investment gains. The Company’s invested 

assets are invested principally in fixed maturity securities. The return on fixed maturity securities is affected primarily by 
general interest rates, as well as the credit quality and duration of the securities.

The Company also invests in equity securities, merger arbitrage securities, investment funds, private equity, loans and 

real estate related assets. The Company's investments in investment funds and its other alternative investments have 
experienced, and the Company expects to continue to experience, greater fluctuations in investment income. The Company's 
share of the earnings or losses from investment funds is generally reported on a one-quarter lag in order to facilitate the timely 
completion of the Company's consolidated financial statements.

In March 2022, the Company sold a real estate investment consisting of an office building located in London for £718 

million. The Company realized a pretax gain of $317 million in the first quarter of 2022, before transaction expenses and the 
impact of foreign currency, including the reversal of the currency translation adjustment. The gain was $251 million after such 
adjustments.

In June 2023, the Company completed a sale of the property and casualty insurance services division of Breckenridge 

IS, Inc. and recognized a pre-tax net realized gain on investment of $89 million.

The ultimate impact of COVID-19 on the Company’s results of operations, financial position and liquidity is not 

within the Company’s control and remains unclear due to, among other factors, its ongoing impact and uncertainty in 
connection with its claims, reserves and reinsurance recoverables.

43

Critical Accounting Estimates

The following presents a discussion of accounting policies and estimates relating to reserves for losses and loss 

expenses, assumed reinsurance premiums and other-than-temporary impairments of investments. Management believes these 
policies and estimates are the most critical to its operations and require the most difficult, subjective and complex judgments. 

Reserves for Losses and Loss Expenses. To recognize liabilities for unpaid losses, either known or unknown, 
insurers establish reserves, which is a balance sheet account representing estimates of future amounts needed to pay claims and 
related expenses with respect to insured events which have occurred. Estimates and assumptions relating to reserves for losses 
and loss expenses are based on complex and subjective judgments, often including the interplay of specific uncertainties with 
related accounting and actuarial measurements. Such estimates are also susceptible to change as significant periods of time may 
elapse between the occurrence of an insured loss, the report of the loss to the insurer, the ultimate determination of the cost of 
the loss and the insurer’s payment of that loss. 

In general, when a claim is reported, claims personnel establish a “case reserve” for the estimated amount of the 

ultimate payment based upon known information about the claim at that time. The estimate represents an informed judgment 
based on general reserving practices and reflects the experience and knowledge of the claims personnel regarding the nature and 
value of the specific type of claim. Reserves are also established on an aggregate basis to provide for losses incurred but not 
reported (“IBNR”) to the insurer, potential inadequacy of case reserves and the estimated expenses of settling claims, including 
legal and other fees and general expenses of administrating the claims adjustment process. Reserves are established based upon 
the then current legal interpretation of coverage provided. 

In examining reserve adequacy, several factors are considered in estimating the ultimate economic value of losses. 

These factors include, among other things, historical data, legal developments, changes in social attitudes and economic 
conditions, including the effects of inflation. The actuarial process relies on the basic assumption that past experience, adjusted 
judgmentally for the effects of current developments and anticipated trends, is an appropriate basis for predicting future 
outcomes. Reserve amounts are based on management’s informed estimates and judgments using currently available data. As 
additional experience and other data become available and are reviewed, these estimates and judgments may be revised. This 
may result in reserve increases or decreases that would be reflected in our results in periods in which such estimates and 
assumptions are changed. 

Reserves do not represent a certain calculation of liability. Rather, reserves represent an estimate of what management 

expects the ultimate settlement and claim administration will cost. While the methods for establishing reserves are well tested 
over time, the major assumptions about anticipated loss emergence patterns are subject to uncertainty. These estimates, which 
generally involve actuarial projections, are based on management’s assessment of facts and circumstances then known, as well 
as estimates of trends in claims severity and frequency, judicial theories of liability and other factors, including the actions of 
third parties which are beyond the Company’s control. These variables are affected by external and internal events, such as 
inflation and economic volatility, judicial and litigation trends, reinsurance coverage, legislative changes and claim handling 
and reserving practices, which make it more difficult to accurately predict claim costs. The inherent uncertainties of estimating 
reserves are greater for certain types of liabilities where long periods of time elapse before a definitive determination of liability 
is made. Because setting reserves is inherently uncertain, the Company cannot provide assurance that its current reserves will 
prove adequate in light of subsequent events. 

Loss reserves included in the Company’s financial statements represent management’s best estimates based upon an 

actuarially derived point estimate and other considerations. The Company uses a variety of actuarial techniques and methods to 
derive an actuarial point estimate for each business. These methods include paid loss development, incurred loss development, 
paid and incurred Bornhuetter-Ferguson methods and frequency and severity methods. In circumstances where one actuarial 
method is considered more credible than the others, that method is used to set the point estimate. For example, the paid loss and 
incurred loss development methods rely on historical paid and incurred loss data. For new lines of business, where there is 
insufficient history of paid and incurred claims data, or in circumstances where there have been significant changes in claim 
practices, the paid and incurred loss development methods would be less credible than other actuarial methods. The actuarial 
point estimate may also be based on a judgmental weighting of estimates produced from each of the methods considered. 
Industry loss experience is used to supplement the Company’s own data in selecting “tail factors” and in areas where the 
Company’s own data is limited. The actuarial data is analyzed by line of business, coverage and accident or policy year, as 
appropriate, for each business. 

The establishment of the actuarially derived loss reserve point estimate also includes consideration of qualitative 

factors that may affect the ultimate losses. These qualitative considerations include, among others, the impact of re-
underwriting initiatives, changes in the mix of business, changes in distribution sources and changes in policy terms and 
conditions. Examples of changes in terms and conditions that can have a significant impact on reserve levels are the use of 
aggregate policy limits, the expansion of coverage exclusions, whether or not defense costs are within policy limits, and 
changes in deductibles and attachment points. 

44

The key assumptions used to arrive at the best estimate of loss reserves are the expected loss ratios, rate of loss cost 

inflation, and reported and paid loss emergence patterns. Expected loss ratios represent management’s expectation of losses at 
the time the business is priced and written, before any actual claims experience has emerged. This expectation is a significant 
determinant of the estimate of loss reserves for recently written business where there is little paid or incurred loss data to 
consider. Expected loss ratios are generally derived from historical loss ratios adjusted for the impact of rate changes, loss cost 
trends and known changes in the type of risks underwritten. Expected loss ratios are estimated for each key line of business 
within each business. Expected loss cost inflation is particularly important for the long-tail lines, such as excess casualty, and 
claims with a high medical component, such as workers’ compensation. Reported and paid loss emergence patterns are used to 
project current reported or paid loss amounts to their ultimate settlement value. Loss development factors are based on the 
historical emergence patterns of paid and incurred losses, and are derived from the Company’s own experience and industry 
data. The paid loss emergence pattern is also significant to excess and assumed workers’ compensation reserves because those 
reserves are discounted to their estimated present value based upon such estimated payout patterns. Management believes the 
estimates and assumptions it makes in the reserving process provide the best estimate of the ultimate cost of settling claims and 
related expenses with respect to insured events which have occurred; however, different assumptions and variables could lead 
to significantly different reserve estimates. 

Loss frequency and severity are measures of loss activity that are considered in determining the key assumptions 
described in our discussion of loss and loss expense reserves, including expected loss ratios, rate of loss cost inflation and 
reported and paid loss emergence patterns. Loss frequency is a measure of the number of claims per unit of insured exposure, 
and loss severity is a measure of the average size of claims. Factors affecting loss frequency include the effectiveness of loss 
controls and safety programs and changes in economic activity or weather patterns. Factors affecting loss severity include 
changes in policy limits, retentions, rate of inflation and judicial interpretations. 

Another factor affecting estimates of loss frequency and severity is the loss reporting lag, which is the period of time 
between the occurrence of a loss and the date the loss is reported to the Company. The length of the loss reporting lag affects 
our ability to accurately predict loss frequency (loss frequencies are more predictable for lines with short reporting lags) as well 
as the amount of reserves needed for incurred but not reported losses (less IBNR is required for lines with short reporting lags). 
As a result, loss reserves for lines with short reporting lags are likely to have less variation from initial loss estimates. For lines 
with short reporting lags, which include auto, primary workers’ compensation, other liability (claims-made) and property 
business, the key assumption is the loss emergence pattern used to project ultimate loss estimates from known losses paid or 
reported to date. For lines of business with long reporting lags, which include other liability (occurrence), products liability, 
excess workers’ compensation and liability reinsurance, the key assumption is the expected loss ratio since there is often little 
paid or incurred loss data to consider. Historically, the Company has experienced less variation from its initial loss estimates for 
lines of businesses with short reporting lags than for lines of business with long reporting lags. 

The key assumptions used in calculating the most recent estimate of the loss reserves are reviewed each quarter and 
adjusted, to the extent necessary, to reflect the latest reported loss data, current trends and other factors observed. If the actual 
level of loss frequency and severity are higher or lower than expected, the ultimate losses will be different than management’s 
estimate. The following table reflects the impact of changes (which could be favorable or unfavorable) in frequency and 
severity, relative to our assumptions, on our loss estimate for claims occurring in 2023:

Our net reserves for losses and loss expenses of approximately $15.7 billion as of December 31, 2023 relate to 

multiple accident years. Therefore, the impact of changes in frequency or severity for more than one accident year could be 
higher or lower than the amounts reflected above. The impact of such changes would likely be manifested gradually over the 
course of many years, as the magnitude of the changes became evident.

Approximately $3.1 billion, or 20%, of the Company’s net loss reserves as of December 31, 2023 relate to the 
Reinsurance & Monoline Excess segment. There is a higher degree of uncertainty and greater variability regarding estimates of 
excess workers' compensation and assumed reinsurance loss reserves. In the case of excess workers’ compensation, our policies 
generally attach at $1 million or higher. The claims which reach our layer therefore tend to involve the most serious injuries and 
many remain open for the lifetime of the claimant, which extends the claim settlement tail. These claims also occur less 
frequently but tend to be larger than primary claims, which increases claim variability. In the case of assumed reinsurance our 
loss reserve estimates are based, in part, upon information received from ceding companies. If information received from 
ceding companies is not timely or correct, the Company’s estimate of ultimate losses may not be accurate. Furthermore, due to 

45

 
 
 
 
 
 
delayed reporting of claim information by ceding companies, the claim settlement tail for assumed reinsurance is also extended. 
Management considers the impact of delayed reporting and the extended tail in its selection of loss development factors for 
these lines of business.

Information received from ceding companies is used to set initial expected loss ratios, to establish case reserves and to 

estimate reserves for incurred but not reported losses on assumed reinsurance business. This information, which is generally 
provided through reinsurance intermediaries, is gathered through the underwriting process and from periodic claim reports and 
other correspondence with ceding companies. The Company performs underwriting and claim audits of selected ceding 
companies to determine the accuracy and completeness of information provided to the Company. The information received 
from the ceding companies is supplemented by the Company’s own loss development experience with similar lines of business 
as well as industry loss trends and loss development benchmarks.

The Company evaluates reserves for losses and loss expenses on a quarterly basis. Changes in estimates of prior year 

losses are reported when such changes are made. The changes in prior year loss reserve estimates are generally the result of 
ongoing analysis of recent loss development trends. Original estimates are increased or decreased as additional information 
becomes known regarding individual claims and aggregate claim trends. 

Certain of the Company's insurance and reinsurance contracts are retrospectively rated, whereby the Company collects 
more or less premiums based on the level of loss activity. For those contracts, changes in loss and loss expenses for prior years 
may be fully or partially offset by additional or return premiums. 

Net prior year development (i.e, the sum of prior year reserve changes and prior year earned premiums changes) for 

each of the last three years ended December 31, are as follows:

The COVID-19 global pandemic has impacted, and may further impact, the Company’s loss costs. Accordingly, the 
ultimate net impact of COVID-19 on the Company's reserves remains uncertain. As of December 31, 2023, the Company had 
recognized losses for COVID-19-related claims activity, net of reinsurance, of approximately $384 million, of which $326 
million relates to the Insurance segment and $58 million relates to the Reinsurance & Monoline Excess segment. Such $384 
million of COVID-19-related losses included $381 million of reported losses and $3 million of IBNR. For the year ended 
December 31, 2023, the Company recognized current accident year losses for COVID-19-related claims activity, net of 
reinsurance, of approximately $1 million, all of which relates to the Insurance segment.

Unfavorable prior year development (net of additional and return premiums) was $19 million in 2023.

Insurance – Reserves for the Insurance segment developed unfavorably by $24 million in 2023 (net of additional and 
return premiums). The unfavorable development for the segment was concentrated in the early part of the year, with reserve 
development being flat overall during the second half of 2023. A key driver of the unfavorable development early in 2023 was 
property catastrophe losses related to 2022 events which were still being adjusted and settled during the early part of 2023. In 
particular, losses related to U.S. winter storms which occurred during the month of December 2022 were a significant 
contributor to the development, as information gathering and evaluation of many of these claims were still ongoing into the new 
year.

In addition to the property prior year development discussed above, during 2023 the Insurance segment also experienced 

adverse prior year development on casualty lines of business for the 2016 through 2019 accident years, which was offset by 
favorable prior year development on casualty lines of business for the 2020 through 2022 accident years. The unfavorable 
development on the 2016 through 2019 accident years was concentrated in the general liability and commercial auto liability 
lines of business. The development, which particularly impacted business attaching excess of primary policy limits, was driven 
by a larger than expected number of large losses reported. The Company believes social inflation is contributing to an increase 
in the frequency of large losses for these accident years. Social inflation can include higher settlement demands from plaintiffs, 
use of tactics such as litigation funding by the plaintiffs’ bar, negative public sentiment towards large businesses and 
corporations, and erosion of tort reforms, among others.

The favorable prior year development on casualty lines for the 2020 through 2022 accident years in the Insurance 
segment was concentrated in the professional liability, workers’ compensation, and general liability lines of business. Due to 
elevated uncertainty regarding incurred loss frequency and severity as a result of ongoing social inflation and the impacts of the 
COVID-19 pandemic, the Company set its initial loss ratios for the 2020 through 2022 accident years prudently, and largely 
maintained these estimates through the end of each respective accident year. The reported loss experience to date for these lines 
of business for the 2020 through 2022 accident years has been significantly better than was expected, and the Company has 
begun to react to this favorable emergence as the accident years mature beyond the age of twelve months. It should also be 
noted that commercial auto liability experienced adverse prior year development for the 2020 through 2022 accident years, 
which partially offset the favorable development discussed above; the adverse development was driven by a larger than 
expected number of large losses reported.  

Reinsurance & Monoline Excess – Reserves for the Reinsurance & Monoline Excess segment developed favorably by $5 

million in 2023 (net of additional and return premiums). The overall favorable prior year development for the segment was 
driven mainly by favorable development in excess workers’ compensation, substantially offset by unfavorable development in 
the non-proportional reinsurance assumed liability and excess general liability (including umbrella) lines of business. The 
favorable excess workers’ compensation development was driven by continued lower claim frequency and reported losses 

47

 
 
 
relative to our expectations, and to favorable claim settlements. The favorable development was spread across many prior 
accident years. The unfavorable development for non-proportional reinsurance assumed liability and excess general liability 
was associated primarily with our U.S. assumed reinsurance business, and related to accounts reinsuring excess and umbrella 
business and construction projects. The adverse development was concentrated mainly in accident years 2017 through 2020. 

Unfavorable prior year development (net of additional and return premiums) was $36 million in 2022.

Insurance – Reserves for the Insurance segment developed unfavorably by $40 million in 2022 (net of additional and 
return premiums). The unfavorable development in the segment primarily related to COVID-19 losses at two businesses. These 
businesses wrote policies providing coverage for event cancellation and film production delay which were heavily impacted by 
losses directly caused by the COVID-19 pandemic. Most of this COVID-19 related unfavorable development emerged during 
the third quarter as a result of settlements of claims at values higher than our expectations. However, the Company believes that 
as a result of these settlements the remaining level of uncertainty around the ultimate value of its known COVID-19 claims has 
been significantly reduced.

The unfavorable development mentioned above also includes favorable prior year development for the Insurance 

segment primarily attributable to the 2020 and 2021 accident years and unfavorable development on the 2015 through 2019 
accident years. The favorable development on the 2020 and 2021 accident years was concentrated in certain casualty lines of 
business including general liability, professional liability, and workers’ compensation. The Company experienced lower 
reported claim frequency in these lines of business during 2020 and 2021 relative to historical averages, and continued to 
experience lower reported incurred losses relative to its expectations for these accident years as they developed during 2022. 
These trends began in 2020 and we believe were caused by the impacts of the COVID-19 pandemic, including for example, 
lockdowns, reduced driving/traffic and increased work from home. Due to the uncertainty regarding the ultimate impacts of the 
pandemic on accident years 2020 and 2021 incurred losses, the Company was cautious in reacting to these lower trends in 
setting and updating its loss ratio estimates for these years. As these accident years have continued to mature, the Company has 
continued to recognize some of the favorable reported experience in its ultimate loss estimates made during 2022.  

The unfavorable development on the 2015 through 2019 accident years was concentrated in the general liability and 
professional liability, including medical professional, lines of business, as well as auto liability. The development was driven by 
a larger than expected number of large losses reported. The Company believes social inflation is contributing to an increase in 
the frequency of large losses for these accident years. Social inflation can include higher settlement demands from plaintiffs, 
use of tactics such as litigation funding by the plaintiffs’ bar, negative public sentiment towards large businesses and 
corporations, and erosion of tort reforms, among others.

Reinsurance & Monoline Excess – Reserves for the Reinsurance & Monoline Excess segment developed favorably by $4 
million in 2022 (net of additional and return premiums). The overall favorable development for the segment was driven mainly 
by favorable development in excess workers compensation, substantially offset by unfavorable development in the professional 
liability and non-proportional reinsurance assumed liability lines of business. The favorable excess workers’ compensation 
development was spread across most prior accident years, including 2012 and prior years, and was driven by a review of the 
Company’s claim reporting patterns as well as a number of favorable claim settlements relative to expectations. The 
unfavorable professional liability and non-proportional reinsurance assumed liability development was concentrated mainly in 
accident years 2016 through 2018 and was associated primarily with our U.S. assumed reinsurance business and related to 
accounts insuring construction projects and professional liability exposures.

Favorable prior year development (net of additional and return premiums) was $7 million in 2021.

Insurance – Reserves for the Insurance segment developed favorably by $20 million in 2021 (net of additional and return 

premiums).  The overall favorable development in 2021 was attributable to favorable development on the 2020 accident year, 
partially offset by adverse development on the 2016 through 2019 accident years.

The favorable development on the 2020 accident year was largely concentrated in the auto liability and other liability 

lines of business, including commercial multi-peril liability. During 2020 the Company achieved larger rate increases in these 
lines of business than were contemplated in its budget and in its initial loss ratio selections. The Company also experienced 
significantly lower reported claim frequency in these lines in 2020 relative to historical averages, and lower reported incurred 
losses relative to its expectations. We believe that the lower claim frequency and lower reported incurred losses were caused by 
the impacts of the COVID-19 pandemic, for example, lockdowns, reduced driving and traffic, work from home, and court 
closures. However, due to the uncertainty regarding the ultimate impacts of the pandemic on accident year 2020 incurred losses, 
the Company elected not to react to these lower reported trends during 2020. As more information became available and the 
2020 accident year continued to mature, during 2021 the Company started to recognize favorable accident year 2020 
development in response to the continuing favorable reported loss experience relative to its expectations.  

48

The adverse development on the 2016 through 2019 accident years is concentrated largely in the other liability line of 

business, including commercial multi-peril liability, but is also seen to a lesser extent in auto liability. The adverse development 
for these accident years is driven by a higher than expected number of large losses reported, and particularly impacted the 
directors and officers liability, lawyers professional liability, and excess and surplus lines casualty classes of business. We also 
believe that increased social inflation is contributing to the increased number of large losses, for example, higher jury awards on 
cases which go to trial, and the corresponding higher demands from plaintiffs and higher values required to reach settlement on 
cases which do not go to trial.

Reinsurance & Monoline Excess – Reserves for the Reinsurance & Monoline Excess segment developed unfavorably by 

$13 million in 2021. The unfavorable development in the segment was driven by the non-proportional reinsurance assumed 
liability and other liability lines of business, related primarily to accident years 2017 through 2019, and was partially offset by 
favorable development in excess workers’ compensation business which was spread across many prior accident years. The 
unfavorable non-proportional reinsurance assumed liability and other liability development was associated with our U.S. and 
U.K. assumed reinsurance business, and related primarily to accounts insuring construction projects and professional liability 
exposures.

Reserve Discount. The Company discounts its liabilities for certain workers’ compensation reserves. The amount of 

workers’ compensation reserves that were discounted was $1,352 million and $1,464 million at December 31, 2023 and 2022, 
respectively. The aggregate net discount for those reserves, after reflecting the effects of ceded reinsurance, was $390 million 
and $416 million at December 31, 2023 and 2022, respectively. At December 31, 2023, discount rates by year ranged from 
0.7% to 6.5%, with a weighted average discount rate of 3.4%.

Substantially all discounted workers’ compensation reserves (97% of total discounted reserves at December 31, 2023) 

are excess workers’ compensation reserves. In order to properly match loss expenses with income earned on investment 
securities supporting the liabilities, reserves for excess workers’ compensation business are discounted using risk-free discount 
rates determined by reference to the U.S. Treasury yield curve. These rates are determined annually based on the weighted 
average rate for the period. Once established, no adjustments are made to the discount rate for that period, and any increases or 
decreases in loss reserves in subsequent years are discounted at the same rate, without regard to when any such adjustments are 
recognized. The expected loss and loss expense payout patterns subject to discounting are derived from the Company’s loss 
payout experience.

The Company also discounts reserves for certain other long-duration workers’ compensation reserves (representing 
approximately 3% of total discounted reserves at December 31, 2023), including reserves for quota share reinsurance and 
reserves related to losses regarding occupational lung disease. These reserves are discounted at statutory rates prescribed or 
permitted by the Department of Insurance of the State of Delaware.

Assumed Reinsurance Premiums. The Company estimates the amount of assumed reinsurance premiums that it will 
receive under treaty reinsurance agreements at the inception of the contracts. These premium estimates are revised as the actual 
amount of assumed premiums is reported to the Company by the ceding companies. As estimates of assumed premiums are 
made or revised, the related amount of earned premiums, commissions and incurred losses associated with those premiums are 
recorded. Estimated assumed premiums receivable were approximately $65 million and $60 million at December 31, 2023 and 
2022, respectively. The assumed premium estimates are based upon terms set forth in reinsurance agreements, information 
received from ceding companies during the underwriting and negotiation of agreements, reports received from ceding 
companies and discussions and correspondence with reinsurance intermediaries. The Company also considers its own view of 
market conditions, economic trends and experience with similar lines of business. These premium estimates represent 
management’s best estimate of the ultimate amount of premiums to be received under its assumed reinsurance agreements.

Allowance for Expected Credit Losses on Investments.

Fixed Maturity Securities – For fixed maturity securities in an unrealized loss position where the Company intends to 
sell, or it is more likely than not that it will be required to sell the security before recovery in value, the amortized cost basis is 
written down to fair value through net investment gains (losses). For fixed maturity securities in an unrealized loss position 
where the Company does not intend to sell, or it is more likely than not that it will not be required to sell the security before 
recovery in value, the Company evaluates whether the decline in fair value has resulted from credit losses or all other factors 
(non-credit factors). In making this assessment, the Company considers the extent to which fair value is less than amortized 
cost, changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among 
other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from 
the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected 
is less than the amortized cost basis, an allowance for expected credit losses is recorded for the credit loss through net 
investment gains (losses), limited by the amount that the fair value is less than the amortized cost basis. The allowance is 
adjusted for any change in expected credit losses and subsequent recoveries through net investment gains (losses). The 

49

impairment related to non-credit factors is recognized in other comprehensive income (loss).

The Company’s credit assessment of allowance for expected credit losses uses a third party model for available for 

sale and held to maturity securities, as well as loans receivable. The allowance for expected credit losses is generally based on 
the performance of the underlying collateral under various economic and default scenarios that involve subjective judgments 
and estimates by management. Modeling these securities involves various factors, such as projected default rates, the nature and 
realizable value of the collateral, if any, the ability of the issuer to make scheduled payments, historical performance and other 
relevant economic and performance factors. A discounted cash flow analysis is used to ascertain the amount of the allowance 
for expected credit losses, if any. In general, the model reverts to the rating-level long-term average marginal default rates based 
on 10 years of historical data, beyond the forecast period. For other inputs, the model in most cases reverts to the baseline long-
term assumptions linearly over 5 years beyond the forecast period. The long-term assumptions are based on the historical 
averages. 

The Company classifies its fixed maturity securities by credit rating, primarily based on ratings assigned by credit 

rating agencies. For purposes of classifying securities with different ratings, the Company uses the average of the credit ratings 
assigned, unless in limited situations the Company’s own analysis indicates an internal rating is more appropriate. Securities 
that are not rated by a rating agency are evaluated and classified by the Company on a case-by-case basis.

As of December 31, 2023, the Company has recorded an allowance for expected credit losses on fixed maturity 
securities of $37 million. The Company has evaluated the remaining fixed maturity securities in an unrealized loss position and 
believes the unrealized losses are due primarily to temporary market and sector-related factors rather than to issuer-specific 
factors. None of these securities are delinquent or in default under financial covenants. Based on its assessment of these issuers, 
the Company expects them to continue to meet their contractual payment obligations as they become due.

Loans Receivable – For loans receivable, the Company estimates an allowance for expected credit losses based on 
relevant information about past events, including historical loss experience, current conditions and forecasts that affect the 
expected collectability of the amortized cost of the financial asset. The allowance for expected credit losses is presented as a 
reduction to amortized cost of the financial asset in the consolidated balance sheet and changes to the estimate for expected 
credit losses are recognized through net investment gains (losses). Loans receivable are reported net of an allowance for 
expected credit losses of $3 million and $2 million as of December 31, 2023 and 2022, respectively.

Fair Value Measurements. The Company’s fixed maturity available for sale securities, equity securities, and its 

trading account securities are carried at fair value. Fair value is defined as "the price that would be received to sell an asset or 
paid to transfer a liability in an orderly transaction between market participants at the measurement date". The Company utilizes 
a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. Level 
1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability 
to access at the measurement date. Level 2 inputs are inputs other than quoted prices included within Level 1 that are 
observable for similar assets in active markets. Level 3 inputs are unobservable inputs for the asset or liability. Unobservable 
inputs may only be used to measure fair value to the extent that observable inputs are not available. The fair value of the vast 
majority of the Company’s portfolio is based on observable data (other than quoted prices) and, accordingly, is classified as 
Level 2.

In classifying particular financial securities in the fair value hierarchy, the Company uses its judgment to determine 

whether the market for a security is active and whether significant pricing inputs are observable. The Company determines the 
existence of an active market by assessing whether transactions occur with sufficient frequency and volume to provide reliable 
pricing information. The Company determines whether inputs are observable based on the use of such information by pricing 
services and external investment managers, the uninterrupted availability of such inputs, the need to make significant 

50

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
adjustments to such inputs and the volatility of such inputs over time. If the market for a security is determined to be inactive or 
if significant inputs used to price a security are determined to be unobservable, the security is categorized in Level 3 of the fair 
value hierarchy.

Because many fixed maturity securities do not trade on a daily basis, the Company utilizes pricing models and 
processes which may include benchmark curves, benchmarking of like securities, sector groupings and matrix pricing. Market 
inputs used to evaluate securities include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided 
markets, benchmark securities, bids, offers and reference data. Quoted prices are often unavailable for recently issued securities 
that are infrequently traded or securities that are only traded in private transactions. For publicly traded securities for which 
quoted prices are unavailable, the Company determines fair value based on independent broker quotations and other observable 
market data. For securities traded only in private negotiations, the Company determines fair value based primarily on the cost of 
such securities, which is adjusted to reflect prices of recent placements of securities of the same issuer, financial data, 
projections and business developments of the issuer and other relevant information.

Independent pricing services - Substantially all of the Company’s fixed maturity securities available for sale were 
priced by independent pricing services (generally one U.S. pricing service plus additional pricing services with respect to a 
limited number of foreign securities held by the Company). The prices provided by the independent pricing services are 
generally based on observable market data in active markets (e.g., broker quotes and prices observed for comparable securities). 
The determination of whether markets are active or inactive is based upon the volume and level of activity for a particular asset 
class. The Company reviews the prices provided by pricing services for reasonableness based upon current trading levels for 
similar securities. If the prices appear unusual to the Company, they are re-examined and the value is either confirmed or 
revised. In addition, the Company periodically performs independent price tests of a sample of securities to ensure proper 
valuation and to verify our understanding of how securities are priced. As of December 31, 2023, the Company did not make 
any adjustments to the prices provided by the pricing services. Based upon the Company’s review of the methodologies used by 
the independent pricing services, these securities were classified as Level 2.

Syndicate manager – The Company has a 15% participation in a Lloyd’s syndicate, and the Company’s share of the 

securities owned by the syndicate is priced by the syndicate’s manager. The majority of the securities are liquid, short duration 
fixed maturity securities. The Company reviews the syndicate manager’s pricing methodology and audited financial statements 
and holds discussions with the syndicate manager as necessary to confirm its understanding and agreement with security prices. 
Based upon the Company’s review of the methodologies used by the syndicate manager, these securities were classified as 
Level 2.

Observable data – If independent pricing is not available, the Company prices the securities directly. Prices are based 

on observable market data where available, including current trading levels for similar securities and non-binding quotations 
from brokers. The Company generally requests two or more quotes. If more than one quote is received, the Company sets a 
price within the range of quotes received based on its assessment of the credibility of the quote and its own evaluation of the 
security. The Company generally does not adjust quotes obtained from brokers. Since these securities were priced based on 
observable data, they were classified as Level 2.

Cash flow model – If the above methodologies are not available, the Company prices securities using a discounted 

cash flow model based upon assumptions as to prevailing credit spreads, interest rates and interest rate volatility, time to 
maturity and subordination levels. Discount rates are adjusted to reflect illiquidity where appropriate. These securities were 
classified as Level 3.

Business Segment Results

Following is a summary of gross and net premiums written, net premiums earned, loss ratios (losses and loss expenses 

incurred expressed as a percentage of net premiums earned), expense ratios (underwriting expenses expressed as a percentage 
of net premiums earned) and GAAP combined ratios (sum of loss ratio and expense ratio) for each of our business segments for 
the years ended December 31, 2023 and 2022. The GAAP combined ratio represents a measure of underwriting profitability, 
excluding investment income. A GAAP combined ratio in excess of 100 indicates an underwriting loss; a number below 100 
indicates an underwriting profit.

The Company reported net income of $1,381 million in both 2023 and 2022. The 2023 net income reflected an after-

tax increase in net investment income of $216 million primarily due to rising interest rates and a larger investment portfolio 
related to fixed maturity securities, an after-tax increase in underwriting income of $38 million mainly due to the growth in 
premium rates, an after-tax reduction in interest expenses of $2 million due to debt repayment in 2022, an after-tax increase in 
profit from insurance service businesses of $1 million and an after-tax increase of $1 million in minority interest, offset by an 
after-tax reduction in net investment gains of $123 million mainly due to the gain on sale of a real estate investment in 2022, an 
after-tax increase in foreign currency losses of $65 million mainly due to weakening of the U.S. dollar against other currencies 
in 2023, an after-tax increase in corporate expenses of $37 million due to increased compensation-related costs, an increase of 
$28 million in tax expense due to a change in the effective tax rate and an after-tax decrease in profits from non-insurance 
businesses of $5 million. The number of weighted average diluted shares decreased by 6.2 million for 2023 compared to 2022, 
mainly reflecting shares repurchased in 2023.

Premiums. Gross premiums written were $12,972 million in 2023, an increase of 9% from $11,909 million in 2022. 
The increase was due to the growth in the Insurance segment of $977 million and $86 million in the Reinsurance & Monoline 
Excess segment. Approximately 81% and 82% of premiums expiring were renewed in 2023 and 2022, respectively.

Average renewal premium rates for insurance and facultative reinsurance increased 7.1% in 2023 and 6.4% in 2022, 
when adjusted for changes in exposures. Average renewal premium rates for insurance and facultative reinsurance excluding 
workers' compensation increased 8.1% in 2023 and 7.5% in 2022, when adjusted for changes in exposures. 

A summary of gross premiums written in 2023 compared with 2022 by line of business within each business segment 

follows:
•

Insurance gross premiums increased 9% to $11,561 million in 2023 from $10,584 million in 2022. Gross premiums 
increased $516 million (13%) for other liability, $454 million (19%) for short-tail lines, $141 million (11%) for auto 
and $10 million (1%) for workers' compensation, partially offset by a reduction of $144 million (9%) for 
professional liability.

•

Reinsurance & Monoline Excess gross premiums increased 6% to $1,411 million in 2023 from $1,325 million in 
2022. Gross premiums written increased $79 million (30%) for property lines and $28 million (12%) for monoline 
excess, partially offset by a reduction of $22 million (3%) for casualty lines. 

Net premiums written were $10,954 million in 2023, an increase of 10% from $10,004 million in 2022. Ceded 

reinsurance premiums as a percentage of gross written premiums were 16% in both 2023 and 2022. 

Premiums earned increased 9% to $10,401 million in 2023 from $9,561 million in 2022. Insurance premiums 
(including the impact of rate changes) are generally earned evenly over the policy term, and accordingly recent rate increases 
will be earned over the upcoming quarters. Premiums earned in 2023 are related to business written during both 2023 and 2022. 
Audit premiums were $363 million in 2023 compared with $312 million in 2022.

Net investment income increased 35% to $1,053 million in 2023 from $779 million in 2022 due primarily to a $380 

million increase in income from fixed maturity securities mainly driven by higher interest rates and a larger investment 
portfolio, a $24 million increase from the arbitrage trading account (including investment income from trading account 
receivables from brokers and clearing organizations), a $3 million increase from equity securities and a $3 million reduction in 
investment expenses, partially offset by a $128 million decrease in income from investment funds primarily due to financial 
service funds and real estate funds and an $8 million decrease in real estate. Investment funds are reported on a one quarter lag. 
The average annualized yield for fixed maturity securities was 4.4% in 2023 and 2.9% in 2022. The effective duration of the 
fixed maturity portfolio was 2.4 years at both December 31, 2023 and 2022. The Company maintained the shortened duration of 
its fixed maturity security portfolio, thereby reducing the potential impact of mark-to-market on the portfolio and positioning 
the Company to react quickly to changes in the current interest rate environment. Average invested assets, at cost (including 
cash and cash equivalents), were $26.4 billion in 2023 and $24.4 billion in 2022.

Insurance Service Fees. The Company earns fees from an insurance distribution business (part of which was sold in 

June 2023), a third-party administrator, and as a servicing carrier of workers' compensation assigned risk plans for certain 
states. Insurance service fees were $106 million in 2023 and $111 million in 2022. The decrease in service fees resulted from
the sale of the property and casualty insurance services division of Breckenridge IS, Inc. 

Net Realized and Unrealized Gains on Investments. The Company buys and sells securities and other investment assets 

on a regular basis in order to maximize its total return on investments. Decisions to sell securities and other investment assets 
are based on management’s view of the underlying fundamentals of specific investments as well as management’s expectations 
regarding interest rates, credit spreads, currency values and general economic conditions. Net realized and unrealized gains on 
investments were $48 million in 2023 compared with $217 million in 2022. In 2023, the gains reflected a change in unrealized 

53

 
 
 
 
 
 
 
 
 
 
 
 
gains on equity securities of $70 million, partially offset by net realized losses on investments of $23 million. In 2022, the gains 
reflected net realized gains on investments of $218 million (primarily due to a $251 million net gain from the sale of a real 
estate investment in London after transaction expenses and the foreign currency impact including reversal of the currency 
translation adjustment), partially offset by a change in unrealized losses on equity securities of $1 million.

Change in Allowance for Expected Credit Losses on Investments. Based on credit factors, the allowance for expected 

credit losses is increased or decreased depending on the percentage of unrealized loss relative to amortized cost by security, 
changes in rating of the security by a rating agency, and adverse conditions specifically related to the security, among other 
factors. In 2023, the pre-tax change in allowance for expected credit losses on investments increased by $498 thousand ($393 
thousand after-tax), which is reflected in net investment gains. In 2022, the pre-tax change in allowance for expected credit 
losses on investments increased by $15 million ($12 million after-tax), which is reflected in net investment gains, primarily due 
to change in estimate.

Revenues from Non-Insurance Businesses. Revenues from non-insurance businesses were derived from businesses 

engaged in the distribution of promotional merchandise, world-wide textile solutions, and aviation-related businesses that 
provide services to aviation markets, including (i) the distribution, manufacturing, repair and overhaul of aircraft parts and 
components, (ii) the sale of new and used aircraft, and (iii) avionics, fuel, maintenance, storage and charter services. Revenues 
from non-insurance businesses were $536 million in 2023 and $510 million in 2022. The increase mainly relates to aviation-
related business and the commercial and residential textile business, which we acquired in 2022, partially offset by the decrease 
of promotional merchandise and existing textile business.

Losses and Loss Expenses. Losses and loss expenses increased to $6,372 million in 2023 from $5,862 million in 2022. 

The consolidated loss ratio was 61.3% in both 2023 and 2022. Catastrophe losses, net of reinsurance recoveries, were $195 
million (including current accident year losses of approximately $1 million related to COVID-19) in 2023 compared with $212 
million (including losses of approximately $5 million related to COVID-19) in 2022. Adverse prior year reserve development 
(net of premium offsets) was $19 million in 2023 and $36 million in 2022 (refer to Note 13 of our consolidated financial 
statements for more detail). The loss ratio excluding catastrophe losses and prior year reserve development was 59.2% and 
58.7% in 2023 and 2022, respectively.

A summary of loss ratios in 2023 compared with 2022 by business segment follows:

•

•

Insurance - The loss ratio was 62.3% in 2023 and 61.3% in 2022. Catastrophe losses were $160 million in 2023 
compared with $127 million in 2022. Adverse prior year reserve development was $24 million in 2023, principally 
from property catastrophe losses, and $40 million in 2022. The loss ratio excluding catastrophe losses and prior year 
reserve development increased 1.0 points to 60.3% in 2023 from 59.3% in 2022. 

Reinsurance & Monoline Excess - The loss ratio was 53.8% in 2023 and 61.3% in 2022. Catastrophe losses were 
$35 million in 2023 compared with $85 million in 2022. Favorable prior year reserve development was $5 million in 
2023 and $4 million in 2022. The loss ratio excluding catastrophe losses and prior year reserve development 
decreased 3.1 points to 51.4% in 2023 from 54.5% in 2022.

Policy acquisition and insurance operating expenses are comprised of commissions paid to agents and brokers, 

premium taxes and other assessments and internal underwriting costs. Policy acquisition and insurance operating expenses 
increased 11% and net premiums earned increased 9% from 2022. The expense ratio (underwriting expenses expressed as a 
percentage of net premiums earned) increased by 0.4 points to 28.4% in 2023 from 28.0% in 2022 mainly due to lower ceding
commissions, increased compensation costs and new start-up operating unit expenses.

Service expenses, which represent the costs associated with the fee-based businesses, was $92 million in 2023, down 

from $96 million in 2022, as a result of the sale of the property and casualty insurance services division of Breckenridge IS, Inc. 

54

 
 
 
 
 
 
Net foreign currency losses (gains) result from transactions denominated in a currency other than a businesses’ 
functional currency. Net foreign currency losses were $32 million in 2023 compared to gains of $51 million in 2022, primarily 
related to the strengthening of the U.K. sterling and Euro against the U.S. dollar in 2023.

Other costs and expenses represent general and administrative expenses of the parent company and other expenses not 

allocated to business segments, including the cost of certain long-term incentive plans and new business ventures. Other costs 
and expenses increased to $286 million in 2023 from $242 million in 2022, primarily due to the increase in compensation-
related costs in 2023. 

Expenses from Non-Insurance Businesses. Expenses from non-insurance businesses represent costs associated with 

businesses engaged in the distribution of promotional merchandise, world-wide textile solutions, and aviation-related 
businesses that include (i) cost of goods sold related to aircraft and products sold and services provided and (ii) general and 
administrative expenses. Expenses from non-insurance businesses were $525 million in 2023 compared to $493 million in 
2022. The increase mainly relates to the aviation-related business and the residential and commercial textile business, which we 
acquired in 2022, partially offset by the decrease of promotional merchandise and existing textile business.

Interest Expense. Interest expense was $127 million in 2023, down from $130 million in 2022, primarily due to the 

repayment at maturity of its $77 million aggregate principal amount of 8.7% senior notes and its $350 million aggregate 
principal amount of 4.625% senior notes in the first quarter of 2022.

Income Taxes. The effective income tax rate was 21.1% in 2023 and 19.5% in 2022. The higher effective income tax 

rate for the year, as compared to 2022, was primarily due to a net reduction to the Company’s valuation allowance against 
foreign tax credits and foreign net operating losses in the earlier period. See Note 16 of the Consolidated Financial Statements 
for a reconciliation of the income tax expense and the amounts computed by applying the Federal income tax rate of 21%.

The Company has not provided U.S. deferred income taxes on the undistributed earnings of approximately $261 

million of its non-U.S. subsidiaries since these earnings are intended to be permanently reinvested in the non-U.S. subsidiaries. 
In the future, if such earnings were distributed the Company projects that the incremental tax, if any, will be immaterial.

On August 16, 2022, the Inflation Reduction Act of 2022 was enacted. Among other things, the legislation introduced 
a corporate alternative minimum tax on certain corporations. The tax is applicable for taxable years beginning after December 
31, 2022 and imposes a 15% minimum tax on a corporation’s applicable financial statement income. While we are not subject 
to this tax in 2023, we continue to evaluate the overall impact of this tax legislation on our operations and U.S. federal income 
tax position. In addition, a 1% excise tax on the value of corporate share repurchases (net of issuance) went into effect on 
January 1, 2023, but was not material for 2023.  

Further, the Company is monitoring the impact of the implementation of a global minimum tax rate of 15%, also 

known as Pillar Two, as introduced by the Organization for Economic Co-operation and Development, which applies in some 
countries commencing in 2024. Our initial assessment is that the impact will not be significant, as the Company mainly 
operates in jurisdictions with a statutory tax rate above 15%.

The “Bermuda Corporate Income Tax Act 2023” was passed into law December 27, 2023 in Bermuda. The income tax 

will be based on a statutory tax rate of 15% on Bermuda businesses, subject to reductions for foreign tax credits, and will be 
effective for fiscal years beginning on or after January 1, 2025. Although we do not currently believe that this will have a 
material impact on our income tax position, we will continue to evaluate this tax legislation in 2024. 

Results of Operations for the Years Ended December 31, 2022 and 2021

For a comparison of the Company’s results of operations for the year ended December 31, 2022 to the year ended 

December 31, 2021, see Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations in 
the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, which was filed with the Securities and 
Exchange Commission on February 24, 2023.

Investments

As part of its investment strategy, the Company establishes a level of cash and highly liquid short-term and intermediate-

term securities that, combined with expected cash flow, it believes is adequate to meet its payment obligations. In addition to 
fixed maturity securities, the Company invests in equity securities, merger arbitrage securities, investment funds, private equity, 
loans and real estate related assets. The Company's investments in investment funds and its other alternative investments have 
experienced, and the Company expects to continue to experience, greater fluctuations in investment income. 

The Company also attempts to maintain an appropriate relationship between the effective duration of the investment 

portfolio and the approximate duration of its liabilities (i.e., policy claims and debt obligations). The effective duration of the 
investment portfolio was 2.4 years at both December 31, 2023 and 2022. The Company’s investment portfolio and investment-
related assets as of December 31, 2023 were as follows:

______________
(1) Pre-refunded securities are securities for which an escrow account has been established to fund the remaining payments of 
principal and interest through maturity. Such escrow accounts are funded almost exclusively with U.S. Treasury and U.S. 
government agency securities.

Fixed Maturity Securities. The Company’s investment policy with respect to fixed maturity securities is generally to 
purchase instruments with the expectation of holding them to their maturity. However, management of the available for sale 

56

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
portfolio is considered necessary to maintain an approximate matching of assets and liabilities as well as to adjust the portfolio 
as a result of changes in financial market conditions and tax considerations.

The Company’s philosophy related to holding or selling fixed maturity securities is based on its objective of maximizing 

total return. The key factors that management considers in its investment decisions as to whether to hold or sell fixed maturity 
securities are its view of the underlying fundamentals of specific securities as well as its expectations regarding interest rates, 
credit spreads and currency values. In a period in which management expects interest rates to rise, the Company may sell longer 
duration securities in order to mitigate the impact of an interest rate rise on the fair value of the portfolio. Similarly, in a period 
in which management expects credit spreads to widen, the Company may sell lower quality securities, and in a period in which 
management expects certain foreign currencies to decline in value, the Company may sell securities denominated in those 
foreign currencies. The sale of fixed maturity securities in order to achieve the objective of maximizing total return may result 
in realized gains; however, there is no reason to expect these gains to continue in future periods.

Equity Securities. Equity securities primarily represent investments in common and preferred stocks in companies with 

potential growth opportunities in different sectors, mainly in the financial institutions and energy sectors.

Investment Funds. At December 31, 2023, the carrying value of investment funds was $1,622 million, including 
investments in financial services funds of $433 million, other funds of $397 million (which includes a deferred compensation 
trust asset of $36 million), transportation funds of $344 million, real estate funds of $202 million, infrastructure funds of $131 
million and energy funds of $115 million. Investment funds are primarily reported on a one-quarter lag.

Real Estate. Real estate is directly owned property held for investment. At December 31, 2023, real estate properties in 

operation included a long-term ground lease in Washington D.C., an office complex in New York City and the completed 
portion of a mixed-use project in Washington D.C. In addition, part of the previously mentioned mixed-use project in 
Washington D.C. is under development. The Company expects to fund further development costs for the project with a 
combination of its own funds and external financing. The Company recognized impairments on real estate of $72 million in 
2023. During the first quarter of 2022, the Company sold an office building in London.

Arbitrage Trading Account. The arbitrage trading account is comprised of direct investments in arbitrage securities. 
Merger arbitrage is the business of investing in the securities of publicly held companies that are the targets in announced 
tender offers and mergers.

Loans Receivable. Loans receivable, net of allowance for expected credit losses, had an amortized cost of $201 million 

and an aggregate fair value of $198 million at December 31, 2023. The amortized cost of loans receivable is net of an allowance 
for expected credit losses of $3 million as of December 31, 2023. Loans receivable include real estate loans of $200 million that 
are secured by commercial and residential real estate located primarily in London and New York. Real estate loans generally 
earn interest at fixed or stepped interest rates and have maturities through 2026. Loans receivable include commercial loans of 
$1 million that are secured by business assets and have fixed interest rates with varying maturities not exceeding 10 years.

57

Liquidity and Capital Resources

Cash Flow. Cash flow provided from operating activities increased to $2,929 million in 2023 from $2,569 million in 

2022, primarily due to an increase in premium receipts partially offset by increased loss and loss expense payments.

The Company's insurance subsidiaries' principal sources of cash are premiums, investment income, service fees and 

proceeds from sales and maturities of portfolio investments. The principal uses of cash are payments for claims, taxes, 
operating expenses and dividends. The Company expects its insurance subsidiaries to fund the payment of losses with cash 
received from premiums, investment income and fees. The Company generally targets an average duration for its investment 
portfolio that is within 1.5 years of the average number of years held for its liabilities so that portions of its investment portfolio 
mature throughout the claim cycle and are available for the payment of claims if necessary. In the event operating cash flow and 
proceeds from maturities and prepayments of fixed maturity securities are not sufficient to fund claim payments and other cash 
requirements, the remainder of the Company's cash and investments is available to pay claims and other obligations as they 
become due. The Company's investment portfolio is highly liquid, with approximately 81% invested in cash, cash equivalents 
and marketable fixed maturity securities as of December 31, 2023. If the sale of fixed maturity securities were to become 
necessary, a realized gain or loss equal to the difference between the cost and sales price of securities sold would be recognized. 

Debt. At December 31, 2023, the Company had senior notes, subordinated debentures and other debt outstanding with a 
carrying value of $2,837 million and a face amount of $2,865 million. The maturities of the outstanding debt are $7 million in 
2024, $3 million in 2025, $250 million in 2037, $350 million in 2044, $470 million in 2050, $400 million in 2052, $185 million 
in 2058, $300 million in 2059, $250 million in 2060, and $650 million in 2061.

On April 1, 2022, the Company entered into a senior unsecured revolving credit facility that provides for revolving, 

unsecured borrowings up to an aggregate of $300 million with a $50 million sublimit for letters of credit. The Company may 
increase the amount available under the facility to a maximum of $500 million subject to obtaining lender commitments for the 
increase and other customary conditions. Borrowings under the facility may be used for working capital and other general 
corporate purposes. All borrowings under the facility must be repaid by April 1, 2027, except that letters of credit outstanding 
on that date may remain outstanding until April 1, 2028 (or such later date approved by all lenders). Our ability to utilize the 
facility is conditioned on the satisfaction of representations, warranties and covenants that are customary for facilities of this 
type. As of December 31, 2023, there were no borrowings outstanding under the facility.

Equity. At December 31, 2023, total common stockholders’ equity was $7.5 billion, common shares outstanding were 
256,544,757 and stockholders’ equity per outstanding share was $29.06. The Company repurchased 8,707,676 and 1,370,394 
shares of its common stock in 2023 and 2022, respectively. The aggregate cost of the repurchases was $537 million in 2023 and 
$94 million in 2022. In 2023, the Board declared regular quarterly cash dividends of $0.10 per share in the first quarter and 
$0.11 per share in each of the remaining three quarters, as well as special dividends of $0.50 per share in the first, third, and 
fourth quarters, for a total of $501 million in aggregate dividends in 2023. 

Total Capital. Total capitalization (equity, debt and subordinated debentures) was $10.3 billion at December 31, 2023. 

The percentage of the Company’s capital attributable to senior notes, subordinated debentures and other debt was 28% and 30% 
at December 31, 2023 and 2022, respectively.

Federal and Foreign Income Taxes

The Company files a consolidated income tax return in the U.S. and foreign tax returns in each of the countries in which 
it has overseas operations. At December 31, 2023, the Company had a gross deferred tax asset of $777 million (which primarily 
relates to, loss and loss expense reserves, unearned premium reserves and unrealized losses on investments). The Company also 
has a $36 million valuation allowance against the gross deferred tax asset and a gross deferred tax liability of $473 million 
(which primarily relates to deferred policy acquisition costs, and various investment funds) resulting in a net deferred tax asset 
of $267 million. The realization of this asset is dependent upon the Company's ability to generate sufficient taxable income in 
future periods. Based on historical results and the prospects for future operations, management anticipates that it is more likely 
than not that future taxable income will be sufficient for the realization of this asset.

Reinsurance 

The Company follows customary industry practice of reinsuring a portion of its exposures in exchange for paying 

reinsurers a part of the premiums received on the policies it writes. Reinsurance is purchased by the Company principally to 
reduce its net liability on individual risks and to protect against catastrophic losses. Although reinsurance does not legally 
discharge an insurer from its primary liability for the full amount of the policies, it does make the assuming reinsurer liable to 
the insurer to the extent of the reinsurance coverage. The Company monitors the financial condition of its reinsurers and 
attempts to place its coverages only with financially sound carriers. Reinsurance coverage and retentions vary depending on the 
line of business, location of the risk and nature of loss. The Company’s reinsurance purchases include the following:

•

Property reinsurance treaties - The Company purchases property reinsurance to reduce its exposure to large individual 
property losses and catastrophe events. Following is a summary of significant property reinsurance treaties in effect as 
of January 1, 2024: 

◦
◦

The Company’s property per risk reinsurance generally covers losses between $2.5 million and $85 million. 

The Company’s catastrophe excess of loss reinsurance program provides protection for business written by its 
Insurance segment businesses and U.S. and non-U.S. business written by Lloyd's Syndicate, excluding 
offshore energy. For 2024, some of our property catastrophe reinsurance is placed via industry loss warranty 
(ILW) covers and the equivalent W. R. Berkley limit and retention (and resulting net position) are estimated 
based on our market share and modeled outcome when applying the ILW layering. Retentions by territory and 
peril range between $62.1 million and $83.6 million. Limits purchased are the difference between the 
corresponding retention and the following amounts:

▪
▪
▪

For terrorism: $700 million.
For Northeast wind exposures: $600 million.
For all other perils and/or territories: $500 million.

•

•

•

•

Casualty reinsurance treaties - The Company purchases casualty reinsurance to reduce its exposure to large individual 
casualty losses, workers’ compensation catastrophe losses and casualty losses involving multiple claimants or insureds 
for the majority of business written by its U.S. companies. A significant casualty treaty (casualty catastrophe) in effect 
as of January 1, 2024 provides protection for losses between $10 million and $70 million from single events with 
claims involving two or more insurable interests or for systemic events involving multiple insureds and/or policy 
years. The treaty also covers casualty contingency losses in excess of $5 million and up to $100 million. We have a co-
participation on this casualty catastrophe treaty. For losses involving two or more claimants for primary workers’ 
compensation business, coverage is generally in place for losses between $10 million and $500 million. For excess 
workers’ compensation business, such coverage is generally in place for losses between $25 million and $500 million. 
Our workers’ compensation catastrophe reinsurance program is a shared cover for both excess and primary workers’ 
compensation business.
Facultative reinsurance - The Company also purchases facultative reinsurance on certain individual policies or risks 
that are in excess of treaty reinsurance capacity. 
Other reinsurance - Depending on the business, the Company purchases specific additional reinsurance to supplement 
the above programs.
Lifson Re will continue to be a participant on the majority of the Company’s reinsurance placements for a 30.0% share 
of the placed amounts. This pertains to all traditional treaty reinsurance/retrocessional placements for both property 
and casualty business where there is more than one open market reinsurer participating. Lifson Re is currently 
capitalized with $380 million of equity from a small group of sophisticated global investors with long-term investment 
horizons, including a minority participation by the Company. Lifson Re will participate on a fully collateralized basis.

The Company places a number of its casualty treaties on a “risk attaching” basis. Under risk attaching treaties, all claims 

from policies incepting during the period of the reinsurance contract are covered even if they occur after the expiration date of 
the reinsurance contract. If the Company is unable to renew or replace its existing reinsurance coverage, protection for 
unexpired policies would remain in place until their expiration. In such case, the Company could revise its underwriting 
strategy for new business to reflect the absence of reinsurance protection. The casualty catastrophe treaty highlighted above was 
purchased on a “losses discovered” basis. Property catastrophe and workers’ compensation catastrophe reinsurance is generally 
placed on a “losses occurring basis,” whereby only claims occurring during the period are covered. If the Company is unable to 
renew or replace these reinsurance coverages, unexpired policies would not be protected, though we generally have the option 
to purchase run-off coverage in our treaties.

(3) Many states require licensed insurers that provide workers' compensation insurance to participate in programs that provide 
workers' compensation to employers that cannot procure coverage from an insurer on a voluntary basis. Insurers can fulfill 
this residual market obligation by participating in pools where results are shared by the participating companies. The 
Company acts as a servicing carrier for workers' compensation pools in certain states. As a servicing carrier, the Company 
writes residual market business directly and then cedes 100% of this business to the respective pool. As a servicing carrier, 
the Company receives fee income for its services. The Company does not retain underwriting risk, and credit risk is limited 
as ceded balances are jointly shared by all the pool members.

The estimated payments for reserves for losses and loss expenses in the above table represent the projected 

(undiscounted) payments for gross loss and loss expense reserves related to losses incurred as of December 31, 2023. The 
estimated payments in the above table do not consider payments for losses to be incurred in future periods. These amounts 
include reserves for reported losses and reserves for incurred but not reported losses. Estimated amounts recoverable from 
reinsurers are not reflected. The estimated payments by year are based on historical loss payment patterns.The actual payments 
may differ from the estimated amounts due to changes in ultimate loss reserves and in the timing of the settlement of those 
reserves. In addition, at December 31, 2023, the Company had commitments to invest up to $339 million and $106 million in 
certain investment funds and real estate construction projects, respectively. These amounts are not included in the above table.

The Company utilizes letters of credit to back certain reinsurance payments and obligations. Outstanding letters of 

credit were $29 million as of December 31, 2023. The Company has made certain guarantees to state regulators that the 
statutory capital of certain subsidiaries will be maintained above certain minimum levels. 

Off-Balance Sheet Arrangements 

An off-balance sheet arrangement is any transaction, agreement or other contractual arrangement involving an 

unconsolidated entity under which a company has (1) made guarantees, (2) a retained or contingent interest in transferred 
assets, (3) an obligation under derivative instruments classified as equity or (4) any obligation arising out of a material variable 
interest in an unconsolidated entity that provides financing, liquidity, market risk or credit risk support to the Company, or that 
engages in leasing, hedging or research and development arrangements with the Company. The Company has no arrangements 
of these types that management believes may have a material current or future effect on our financial condition, liquidity or 
results of operations.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk. The fair value of the Company’s investments is subject to risks of fluctuations in credit quality and interest 

rates. The Company uses various models and stress test scenarios to monitor and manage interest rate risk. The Company 
attempts to manage its interest rate risk by maintaining an appropriate relationship between the effective duration of the 
investment portfolio and the average number of years held for its liabilities (i.e., policy claims and debt obligations). The 
effective duration for the fixed maturity portfolio (including cash and cash equivalents) was 2.4 years at both December 31, 
2023 and 2022. 

In addition, the fair value of the Company’s international investments is subject to currency risk. The Company attempts 

to manage its currency risk by matching its foreign currency assets and liabilities where considered appropriate.

The following table outlines the groups of fixed maturity securities and their effective duration at December 31, 2023:

Duration is a common measure of the price sensitivity of fixed maturity securities to changes in interest rates. The 

Company determines the estimated change in fair value of the fixed maturity securities, assuming parallel shifts in the yield 
curve for treasury securities while keeping spreads between individual securities and treasury securities static. The estimated 
fair value at specified levels at December 31, 2023 would be as follows:

Arbitrage investing differs from other types of investments in that its focus is on transactions and events believed likely 

to bring about a change in value over a relatively short time period (usually four months or less). The Company believes that 
this makes arbitrage investments less vulnerable to changes in general stock market conditions. Potential changes in market 
conditions are also mitigated by the implementation of hedging strategies, including short sales.

Additionally, the arbitrage positions are generally hedged against market declines by purchasing put options, selling call 

options or entering into swap contracts. The Company's merger arbitrage securities are primarily exposed to the risk of 
completion of announced deals, which are subject to regulatory as well as transactional and other risks.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors
W. R. Berkley Corporation:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of W. R. Berkley Corporation and subsidiaries (the Company) 
as of December 31, 2023 and 2022, the related consolidated statements of income, comprehensive income, stockholders’ 
equity, and cash flows for each of the years in the three-year period ended December 31, 2023, and the related notes and 
financial statement schedules II to VI (collectively, the consolidated financial statements). In our opinion, the consolidated 
financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 
2022, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 
2023, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the Company’s internal control over financial reporting as of December 31, 2023, based on criteria established in 
Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway 
Commission, and our report dated February 23, 2024 expressed an unqualified opinion on the effectiveness of the Company’s 
internal control over financial reporting.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express 
an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the 
PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and 
the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, 
whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the 
consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such 
procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial 
statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, 
as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a 
reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial 
statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or 
disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or 
complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated 
financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate 
opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Reserves for losses and loss expenses

As discussed in Notes 1 and 13 to the consolidated financial statements, the Company estimates the reserves for losses and 
loss expenses (reserves) using a variety of actuarial techniques and methods. The key assumptions used to arrive at the 
best estimate of recorded reserves are expected loss ratios, rate of loss cost inflation, reported and paid loss emergence 
patterns, loss frequency and severity, and the loss reporting lag. Such amounts are adjusted for certain qualitative factors. 
The reserves as of December 31, 2023 were $18.7 billion. 

We identified the assessment of the estimate of reserves as a critical audit matter because it involved significant 
measurement uncertainty, which required complex auditor judgement. Specialized actuarial skills and knowledge were 
required to evaluate the actuarial method or methods and assumptions used. Assumptions included loss development 

63

factors; the weighting of actuarial methods when more than one was used; the impact of qualitative factors; and whether 
payments are fixed and reliably determinable for certain reserves subject to discounting. 

The following are the primary procedures we performed to address the critical audit matter. With the assistance of 
actuarial professionals, when appropriate, we evaluated the design and tested the operating effectiveness of certain internal 
controls over the Company’s reserving process. This included controls over the Company’s process to develop the 
Company’s best estimate of reserves based on actuarial methodologies and assumptions employed by the Company’s 
actuaries. We involved actuarial professionals with specialized skills and knowledge, who assisted in:

•
•

•

•

•

•

examining the Company’s actuarial methodologies for compliance with Actuarial Standards of Practice 
evaluating the Company’s ability to discount certain reserves by comparing the expected payout pattern of claims paid 
to actual claims paid 
evaluating the Company’s actuarial point estimate by performing independent actuarial analyses for certain of the 
larger, more complex businesses 
evaluating the Company’s actuarial point estimate by examining the Company actuaries’ process, and key assumptions 
for certain of the remaining businesses 
developing an independent range of reserves based on actuarial methodologies and assumptions and comparing to the 
Company’s recorded reserves
evaluating the Company’s recorded reserves and year-over-year movements of the Company’s reserves relative to, and 
within, the independently developed range of reserves.

We have served as the Company’s auditor since 1972.

W. R. BERKLEY CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

For the years ended December 31, 2023, 2022 and 2021 

(1)  Summary of Significant Accounting Policies

(A) Principles of consolidation and basis of presentation 

The consolidated financial statements, which include the accounts of W. R. Berkley Corporation and its subsidiaries 
(the "Company"), have been prepared on the basis of U.S. generally accepted accounting principles ("GAAP"). All significant 
intercompany transactions and balances have been eliminated. Reclassifications have been made in the 2022 and 2021 financial 
statements as originally reported to conform to the presentation of the 2023 financial statements. For the year ended December 
31, 2021, the Company did not correct the proceeds from sale of fixed maturity securities and purchase of fixed maturity 
securities lines within the consolidated statements of cash flows for an incremental inter-company elimination as the effects 
were not material and had no impact on the total amount of investing activities.

The preparation of financial statements in conformity with GAAP requires management to make estimates and 

assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the 
date of the financial statements and the revenues and expenses reflected during the reporting period. The most significant items 
on our balance sheet that involve a greater degree of accounting estimates that are subject to change in the future are the 
valuation of investments, allowance for expected credit losses on investments, reserves for losses and loss expenses and 
premium estimates. Actual results could differ from those estimates. 

(B) Revenue recognition 

Insurance premiums are recognized as written at the inception of the policy. Reinsurance premiums are estimated 

based upon information received from ceding companies, and subsequent differences from such estimates are recorded in the 
period they are determined. Insurance and reinsurance premiums are primarily earned on a pro rata basis over the policy term. 
Fees for services are earned over the period that the services are provided. Premiums and fees receivable are reported net of an 
allowance for expected credit losses, with the allowance being estimated based on current and future expected conditions, 
historical loss data and specific identification of collectability concerns where applicable. Changes in the allowance are reported 
within other operating costs and expenses.

Audit premiums are recognized when they are reliably determinable. The change in accruals for earned but unbilled 

audit premiums increased net premiums written and premiums earned by $19 million, $25 million and $10 million in 2023, 
2022 and 2021, respectively.

Revenues from non-insurance businesses are derived from businesses engaged in the distribution of promotional 
merchandise, world-wide textile solutions, and aircraft services provided to the general, commercial and military aviation 
markets. These aircraft services include (i) the distribution, manufacturing, repair and overhaul of aircraft parts and 
components, (ii) the sale of new and used aircraft, and (iii) avionics, fuel, maintenance, storage and charter services. Revenue is 
recognized upon the shipment of products and parts, the delivery of aircraft, the delivery of fuel, and over the completion period 
of services.

Insurance service fee revenue represents servicing fees for program administration and claims management services 

provided by the Company, including workers' compensation assigned risk plans, as well as insurance brokerage and risk 
management services. Fees for program administration, claims management and risk management services are primarily 
recognized ratably over the related contract period for which the underlying services are rendered.

(C) Cash and cash equivalents

Cash equivalents consist of funds invested in money market accounts and investments with an effective maturity of 

three months or less when purchased.

(D) Investments

Fixed maturity securities classified as available for sale are carried at estimated fair value, with unrealized gains and 
losses, net of applicable income taxes, excluded from earnings and reported as a component of comprehensive income and a 
separate component of stockholders' equity. Fixed maturity securities that the Company has the positive intent and ability to 
hold to maturity are classified as held to maturity and reported at amortized cost. Investment income from fixed maturity 
securities is recognized based on the constant effective yield method. Premiums and discounts on mortgage-backed securities 
are adjusted for the effects of actual and anticipated prepayments on a retrospective basis. 

70

Equity securities with readily determinable fair values are measured at fair value, with changes in the fair value 

recognized in net income within net realized and unrealized gains on investments.

Fixed maturity securities that the Company purchased with the intent to sell in the near-term are classified as trading 
account securities and are reported at estimated fair value. Realized and unrealized gains and losses from trading activity are 
reported as net investment income and are recorded at the trade date. Short sales and short call options are presented as trading 
securities sold but not yet purchased. Unsettled trades and the net margin balances held by the clearing broker are presented as a 
trading account receivable from brokers and clearing organizations.

Investment funds are carried under the equity method of accounting. The Company's share of the earnings or losses of 

investment funds is primarily reported on a one-quarter lag in order to facilitate the timely completion of the Company's 
consolidated financial statements.

Loans receivable primarily represent commercial and real estate loans and are carried at amortized cost. The accrual of 

interest on loans receivable is discontinued if the loan is 90 days past due based on the contractual terms of the loan unless the 
loan is adequately secured and in process of collection. In general, loans are placed on non-accrual status or charged off at an 
earlier date if collection of principal or interest is considered doubtful. Interest on these loans is accounted for on a cash basis 
until qualifying for return to accrual status. Loans are returned to accrual status when all principal and interest amounts 
contractually due are brought current and future payments are reasonably assured.

Fair value is defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly 

transaction between market participants at the measurement date.” Fair value of investments is determined based on a fair value 
hierarchy that prioritizes the use of observable inputs over the use of unobservable inputs and requires the use of observable 
inputs when available. (See Note 12 of the Notes to Consolidated Financial Statements.)

Realized gains or losses represent the difference between the cost of securities sold and the proceeds realized upon sale 

and are recorded at the trade date. The Company uses primarily the first-in, first-out method to determine the cost of securities 
sold.

For available for sale securities in an unrealized loss position where the Company intends to sell, or it is more likely 

than not that it will be required to sell the security before recovery in value, the amortized cost basis is written down to fair 
value through net investment gains. For available for sale securities in an unrealized loss position where the Company does not 
intend to sell, or it is more likely than not that it will not be required to sell the security before recovery in value, the Company 
evaluates whether the decline in fair value has resulted from credit losses or all other factors (non-credit factors). In making this 
assessment, the Company considers the extent to which fair value is less than amortized cost, changes to the rating of the 
security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment 
indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the 
amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost 
basis, an allowance for expected credit losses is recorded for the credit loss through net investment gains, limited by the amount 
that the fair value is less than the amortized cost basis. The allowance is adjusted for any change in expected credit losses and 
subsequent recoveries through net investment gains. The impairment related to non-credit factors is recognized in 
comprehensive income (loss).

For financial assets carried at amortized cost, which includes held to maturity securities and loans receivable, the 

Company estimates an allowance for expected credit losses based on relevant information about past events, including historical 
loss experience, current conditions and forecasts that affect the expected collectability of the amortized cost of the financial 
asset. The allowance for expected credit losses is presented as a reduction to amortized cost of the financial asset in the 
consolidated balance sheet and changes to the estimate for expected credit losses are recognized through net investment gains.

The Company’s credit assessment of allowance for expected credit losses uses a third party model for available for 

sale and held to maturity securities, as well as loans receivable. The allowance for expected credit losses is generally based on 
the performance of the underlying collateral under various economic and default scenarios that involve subjective judgments 
and estimates by management. Modeling these securities involves various factors, such as projected default rates, the nature and 
realizable value of the collateral, if any, the ability of the issuer to make scheduled payments, historical performance and other 
relevant economic and performance factors. A discounted cash flow analysis is used to ascertain the amount of the allowance 
for expected credit losses, if any. In general, the model reverts to the rating-level long-term average marginal default rates based 
on 10 years of historical data, beyond the forecast period. For other inputs, the model in most cases reverts to the baseline long-
term assumptions linearly over 5 years beyond the forecast period. The long-term assumptions are based on the historical 
averages.

71

The Company reports accrued investment income separately from fixed maturity securities, and has elected not to 
measure an allowance for expected credit losses for accrued investment income. Accrued investment income is written off 
through net investment income at the time the issuer of the bond defaults or is expected to default on payments.

Real estate held for investment purposes is initially recorded at the purchase price, which is generally fair value, and is 

subsequently reported at cost less accumulated depreciation. Real estate taxes, interest and other costs incurred during 
development and construction are capitalized. Buildings are depreciated on a straight-line basis over the estimated useful lives 
of the building. Minimum rental income is recognized on a straight-line basis over the lease term. Income and expenses from 
real estate are reported as net investment income. The carrying value of real estate is reviewed for impairment and an 
impairment loss is recognized if the estimated undiscounted cash flows from the use and disposition of the property are less 
than the carrying value of the property.

(E) Per share data 

The Company presents both basic and diluted net income per share (“EPS”) amounts. Basic EPS is calculated by 

dividing net income by weighted average number of common shares outstanding during the year (including 11,663,450 
common shares held in a grantor trust). The common shares held in the grantor trust are for delivery upon settlement of vested 
but mandatorily deferred restricted stock units ("RSUs"). Shares held by the grantor trust do not affect diluted shares 
outstanding since the shares deliverable under vested RSUs were already included in diluted shares outstanding. Diluted EPS is 
based upon the weighted average number of basic and common equivalent shares outstanding during the year and is calculated 
using the treasury stock method for stock incentive plans. Common equivalent shares are excluded from the computation in 
periods in which they have an anti-dilutive effect. 

(F) Deferred policy acquisition costs 

Acquisition costs associated with the successful acquisition of new and renewed insurance and reinsurance contracts 

are deferred and amortized ratably over the terms of the related contracts. Ceding commissions received on reinsurance 
contracts are netted against acquisition costs and are recognized ratably over the life of the contract. Deferred policy acquisition 
costs are presented net of unearned ceding commissions. Deferred policy acquisition costs are comprised primarily of 
commissions, as well as employment-related underwriting costs and premium taxes. Deferred policy acquisition costs are 
reviewed to determine if they are recoverable from future income and, if not, are charged to expense. The recoverability of 
deferred policy acquisition costs is evaluated separately by each of our operating units. Future investment income is taken into 
account in measuring the recoverability of deferred policy acquisition costs.

(G) Reserves for losses and loss expenses 

Reserves for losses and loss expenses are an accumulation of amounts determined on the basis of (1) evaluation of 

claims for business written directly by the Company; (2) estimates received from other companies for reinsurance assumed by 
the Company; and (3) estimates for losses incurred but not reported (based on Company and industry experience). These 
estimates are periodically reviewed and, as experience develops and new information becomes known, the reserves are adjusted 
as necessary. Such adjustments are reflected in the statements of income in the period in which they are determined. The 
Company discounts its reserves for excess and assumed workers' compensation claims using a risk-free or statutory rate. (See 
Note 13 of Notes to Consolidated Financial Statements.)

(H) Reinsurance ceded 

The unearned portion of premiums ceded to reinsurers is reported as prepaid reinsurance premiums and earned ratably 

over the policy term. The estimated amounts of reinsurance recoverable on unpaid losses are reported as due from reinsurers. 
To the extent any reinsurer does not meet its obligations under reinsurance agreements, the Company must discharge its 
liability. Amounts due from reinsurers are reflected net of funds held where the right of offset is present. The Company has 
provided an allowance for expected credit losses for estimated uncollectible reinsurance. The allowance is estimated based on 
the composition of the recoverable balance, considering reinsurer credit ratings, collateral received from financial institutions 
and funds withheld arrangements, length of collection periods, probability of default methodology, and specific identification of 
collectability concerns. Changes in the allowance are reported within losses and loss expenses.

(I) Deposit accounting 

Contracts that do not meet the risk transfer requirements of GAAP are accounted for using the deposit accounting 
method. Under this method, an asset or liability is recognized at the inception of the contract based on consideration paid or 
received. The amount of the deposit asset or liability is adjusted at subsequent reporting dates using the interest method with a 

72

corresponding credit or charge to interest income or expense. Deposit liabilities for assumed reinsurance contracts were $31 
million and $33 million at December 31, 2023 and 2022, respectively. 

(J) Federal and foreign income taxes

The Company files a consolidated income tax return in the U.S. and foreign tax returns in countries where it has 
overseas operations. The Company's method of accounting for income taxes is the asset and liability method. Under this 
method, deferred tax assets and liabilities are measured using tax rates currently in effect or expected to apply in the years in 
which those temporary differences are expected to reverse. Interest and penalties, if any, are reported as income tax expense. 
The Company believes there are no uncertain tax positions that would require disclosure under GAAP. Deferred tax assets are 
reduced by a valuation allowance if it is more likely than not that all or a portion of the deferred tax assets will not be realized. 

(K) Foreign currency 

Gains and losses resulting from foreign currency transactions (transactions denominated in a currency other than the 

entity's functional currency) are reported on the statements of income as other operating costs and expenses. Unrealized gains or 
losses resulting from translating the results of non-U.S. dollar denominated operations are reported in accumulated other 
comprehensive income. Revenues and expenses denominated in currencies other than U.S. dollars are generally translated at the 
weighted average exchange rate during the year. Assets and liabilities are translated at the rate of exchange in effect at the 
balance sheet date. 

(L) Property, furniture and equipment 

Property, furniture and equipment are carried at cost less accumulated depreciation. Depreciation is calculated using 

the estimated useful lives of the respective assets. Depreciation expense was $51 million, $52 million and $52 million for 2023, 
2022 and 2021, respectively.

(M) Comprehensive income

Comprehensive income encompasses all changes in stockholders' equity (except those arising from transactions with 

stockholders) and includes net income, net unrealized holding gains or losses on available for sale securities and unrealized 
foreign currency translation adjustments.

(N) Goodwill and other intangible assets 

Goodwill and other intangible assets are tested for impairment on an annual basis and at interim periods where 

circumstances require. The Company's impairment test as of December 31, 2023 indicated that there were no material 
impairment losses related to goodwill and other intangible assets. Intangible assets of $119 million and $102 million are 
included in other assets as of December 31, 2023 and 2022, respectively. 

(O) Restricted stock units 

The costs resulting from all share-based payment transactions with employees are recognized in the consolidated 

financial statements using a fair-value-based measurement method. Compensation cost is recognized for financial reporting 
purposes over the period in which the employee is required to provide service in exchange for the award (generally the vesting 
period).

(P) Statements of cash flows

Interest payments were $114 million, $138 million and $141 million in 2023, 2022 and 2021, respectively. Income 

taxes paid were $332 million, $295 million and $244 million in 2023, 2022 and 2021, respectively. Other non-cash items 
include unrealized investment gains and losses. (See Note 10 of Notes to Consolidated Financial Statements.)

(Q) Recent accounting pronouncements

Recently adopted accounting pronouncements:

All accounting and reporting standards that became effective in 2023 were either not applicable to the Company or 

their adoption did not have a material impact on the Company.

Accounting and reporting standards that are not yet effective:

73

All recently issued but not yet effective accounting and reporting standards are either not applicable to the Company or 

are not expected to have a material impact on the Company.

During the year ended December 31, 2023, the Company decreased the allowance for expected credit losses for 
available for sale securities utilizing its credit loss assessment process and inputs used in its credit loss model due to a reduction 
in unrealized losses primarily associated with foreign government securities. During the year ended December 31, 2022, the 
Company increased the allowance for expected credit losses for available for sale securities due to an increase in unrealized 
losses primarily associated with foreign government securities. 

The amortized cost and fair value of fixed maturity securities at December 31, 2023, by contractual maturity, are 
shown below. Actual maturities may differ from contractual maturities because certain issuers may have the right to call or 
prepay obligations.

(5)  Arbitrage Trading Account

At December 31, 2023 and 2022, the fair value and carrying value of the arbitrage trading account were $938 million 

and $944 million, respectively. The primary focus of the trading account is merger arbitrage. Merger arbitrage is the business of 
investing in the securities of publicly held companies which are the targets in announced tender offers and mergers. Arbitrage 
investing differs from other types of investing in its focus on transactions and events believed likely to bring about a change in 
value over a relatively short time period (usually four months or less). 

The Company uses put options and call options in order to mitigate the impact of potential changes in market 
conditions on the merger arbitrage trading account. These options are reported at fair value. As of December 31, 2023, the fair 
value of long option contracts outstanding was $185 thousand (notional amount of $75 million) and the fair value of short 
option contracts outstanding was $9 million (notional amount of $75 million). Other than with respect to the use of these 
trading account securities, the Company does not make use of derivatives.

(7)  Investment Funds

The Company evaluates whether it is an investor in a variable interest entity ("VIE").  Such entities do not have 

sufficient equity at risk to finance their activities without additional subordinated financial support, or the equity investors, as a 
group, do not have the characteristics of a controlling financial interest (primary beneficiary). The Company determines 
whether it is the primary beneficiary of an entity subject to consolidation based on a qualitative assessment of the VIE's capital 
structure, contractual terms, nature of the VIE's operations and purpose, and the Company's relative exposure to the related risks 
of the VIE on the date it becomes initially involved in the VIE and on an ongoing basis. The Company is not the primary 
beneficiary in any of its investment funds, and accordingly, carries its interests in investments funds under the equity method of 
accounting.

The Company’s maximum exposure to loss with respect to these investments is limited to the carrying amount 

reported on the Company’s consolidated balance sheet and its unfunded commitments of $339 million as of December 31, 
2023.

The Company's share of the earnings or losses of investment funds is primarily reported on a one-quarter lag in order 

to facilitate the timely completion of the Company's consolidated financial statements. 

Financial services investment funds include the Company’s minority investment in Lifson Re, a Bermuda reinsurance 

company. Effective January 1, 2021, Lifson Re participated on a fully collateralized basis in a majority of the Company’s 
reinsurance placements for a 22.5% share of placed amounts. The percentage increased from 22.5% to 30.0% effective July 1, 
2022. This pertains to all traditional reinsurance/retrocessional placements for both property and casualty business where there 
is more than one open market reinsurer participating. For the years ended December 31, 2023 and 2022, the Company ceded 
approximately $437 million and $399 million, respectively, of written premiums to Lifson Re.

Other funds include deferred compensation trust assets of $36 million and $30 million in 2023 and 2022, respectively. 
These assets support other liabilities reflected in the balance sheet of an equal amount for employees who have elected to defer 
a portion of their compensation. The change in the net asset value of the trust is recorded in other funds within net investment 
income with an offsetting equal amount within corporate expenses.

The real estate loans are secured by commercial and residential real estate primarily located in London and New York. 

These loans generally earn interest at fixed or stepped interest rates and have maturities through 2026. The commercial loans 
are with small business owners who have secured the related financing with the assets of the business. Commercial loans 
primarily earn interest on a fixed basis and have varying maturities generally not exceeding 10 years. 

In 2023, the Company recognized an $18.8 million impairment on commercial loans.  

Loans receivable in non-accrual status was none and $0.2 million as of December 31, 2023 and 2022, respectively.

During the year ended December 31, 2023, the Company increased the allowance for expected credit losses due to 

changes in economic assumptions utilized in its credit loss model. 

The Company monitors the performance of its loans receivable and assesses the ability of the borrower to pay 

principal and interest based upon loan structure, underlying property values, cash flow and related financial and operating 
performance of the property and market conditions.

In evaluating the real estate loans, the Company considers their credit quality indicators, including loan to value ratios, 

which compare the outstanding loan amount to the estimated value of the property, the borrower’s financial condition and 
performance with respect to loan terms, the position in the capital structure, the overall leverage in the capital structure and 
other market conditions.

the foreign government classification. A significant amount of the unrealized loss on foreign government securities is the result 
of changes in currency exchange rates.

For fixed maturity securities that management does not intend to sell or to be required to sell, the portion of the decline 

in value that is considered to be due to credit factors is recognized in earnings, and the portion of the decline in value that is 
considered to be due to non-credit factors is recognized in other comprehensive income.

The Company has evaluated its fixed maturity securities in an unrealized loss position and believes the unrealized 
losses are due primarily to temporary market and sector-related factors rather than to issuer-specific factors. None of these 
securities are delinquent or in default under financial covenants. Based on its assessment of these issuers, the Company expects 
them to continue to meet their contractual payment obligations as they become due.

(12)  Fair Value Measurements

The Company’s fixed maturity and equity securities classified as available for sale and its trading account securities 

are carried at fair value. Fair value is defined as “the price that would be received to sell an asset or paid to transfer a liability in 
an orderly transaction between market participants at the measurement date”. The Company utilizes a fair value hierarchy that 
prioritizes the inputs to valuation techniques used to measure fair value into three broad levels, as follows:

Level 1 - Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability 
to access at the measurement date.  

Level 2 - Quoted prices for similar assets or valuations based on inputs that are observable.  

Level 3 - Estimates of fair value based on internal pricing methodologies using unobservable inputs. Unobservable 
inputs are only used to measure fair value to the extent that observable inputs are not available. 

Substantially all of the Company’s fixed maturity securities were priced by independent pricing services. The prices 

provided by the independent pricing services are estimated based on observable market data in active markets utilizing pricing 
models and processes, which may include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided 
markets, benchmark securities, bids, offers, sector groupings, matrix pricing and reference data. The pricing services may 
prioritize inputs differently on any given day for any security based on market conditions, and not all inputs are available for 
each security evaluation on any given day. The pricing services used by the Company have indicated that they will only 
produce an estimate of fair value if objectively verifiable information is available. The determination of whether markets are 
active or inactive is based upon the volume and level of activity for a particular asset class. The Company reviews the prices 
provided by pricing services for reasonableness and periodically performs independent price tests of a sample of securities to 
ensure proper valuation.

If prices from independent pricing services are not available for fixed maturity securities, the Company estimates the 

fair value. For Level 2 securities, the Company utilizes pricing models and processes which may include benchmark yields, 
sector groupings, matrix pricing, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, bids, offers and 
reference data. Where broker quotes are used, the Company generally requests two or more quotes and sets a price within the 
range of quotes received based on its assessment of the credibility of the quote and its own evaluation of the security. The 
Company generally does not adjust quotes received from brokers. For securities traded only in private negotiations, the 
Company determines fair value based primarily on the cost of such securities, which is adjusted to reflect prices of recent 
placements of securities of the same issuer, financial projections, credit quality and business developments of the issuer and 
other relevant information. 

For Level 3 securities, the Company generally uses a discounted cash flow model to estimate the fair value of fixed 

maturity securities. The cash flow models are based upon assumptions as to prevailing credit spreads, interest rate and interest 
rate volatility, time to maturity and subordination levels. Projected cash flows are discounted at rates that are adjusted to reflect 
illiquidity, where appropriate.

(13) Reserves for Losses and Loss Expenses 

The Company's reserves for losses and loss expenses are comprised of case reserves and incurred but not reported 

liabilities (IBNR). When a claim is reported, a case reserve is established for the estimated ultimate payment based upon known 
information about the claim. As more information about the claim becomes available over time, case reserves are adjusted up or 
down as appropriate. Reserves are also established on an aggregate basis to provide for IBNR liabilities and expected loss 
reserve development on reported claims.

Loss reserves included in the Company’s financial statements represent management’s best estimates based upon an 

actuarially derived point estimate and other considerations. The Company uses a variety of actuarial techniques and methods to 
derive an actuarial point estimate for each business. These methods may include paid loss development, incurred loss 
development, paid and incurred Bornhuetter-Ferguson methods and frequency and severity methods. In circumstances where 
one actuarial method is considered more credible than the others, that method is used to set the point estimate. The actuarial 
point estimate may also be based on a judgmental weighting of estimates produced from each of the methods considered. 
Industry loss experience is used to supplement the Company’s own data in selecting “tail factors” in areas where the 
Company’s own data is limited. The actuarial data is analyzed by line of business, coverage and accident or policy year, as 
appropriate, for each business.

The establishment of the actuarially derived loss reserve point estimate also includes consideration of qualitative 

factors that may affect the ultimate losses. These qualitative considerations include, among others, the impact of re-
underwriting initiatives, changes in claims handling procedures, changes in the mix of business, changes in distribution sources 
and changes in policy terms and conditions.

The key assumptions used to arrive at the best estimate of loss reserves are the expected loss ratios, rate of loss cost 

inflation, and reported and paid loss emergence patterns. Expected loss ratios represent management’s expectation of losses at 
the time the business is priced and written, before any actual claims experience has emerged. This expectation is a significant 
determinant of the estimate of loss reserves for recently written business where there is little paid or incurred loss data to 
consider. Expected loss ratios are generally derived from historical loss ratios adjusted for the impact of rate changes, loss cost 
trends and known changes in the type of risks underwritten. Expected loss ratios are estimated for each key line of business 
within each business. Expected loss cost inflation is particularly important for the long-tail lines, such as excess casualty, and 
claims with a high medical component, such as workers’ compensation. Reported and paid loss emergence patterns are used to 
project current reported or paid loss amounts to their ultimate settlement value. Loss development factors are based on the 
historical emergence patterns of paid and incurred losses, and are derived from the Company’s own experience and industry 
data. The paid loss emergence pattern is also significant to excess and assumed workers’ compensation reserves because those 
reserves are discounted to their estimated present value based upon such estimated payout patterns.

Loss frequency and severity are measures of loss activity that are considered in determining the key assumptions 
described in our discussion of loss and loss expense reserves, including expected loss ratios, rate of loss cost inflation and 
reported and paid loss emergence patterns. Loss frequency is a measure of the number of claims per unit of insured exposure, 
and loss severity is a measure of the average size of claims. Factors affecting loss frequency include the effectiveness of loss 
controls and safety programs and changes in economic activity or weather patterns. Factors affecting loss severity include 
changes in policy limits, retentions, rate of inflation and judicial interpretations.

Another factor affecting estimates of loss frequency and severity is the loss reporting lag, which is the period of time 
between the occurrence of a loss and the date the loss is reported to the Company. The length of the loss reporting lag affects 
our ability to accurately predict loss frequency (loss frequencies are more predictable for lines with short reporting lags) as well 
as the amount of reserves needed for incurred but not reported losses (less IBNR is required for lines with short reporting lags). 
As a result, loss reserves for lines with short reporting lags are likely to have less variation from initial loss estimates. For lines 
with short reporting lags, which include auto, primary workers’ compensation, other liability (claims-made) and property 
business, the key assumption is the loss emergence pattern used to project ultimate loss estimates from known losses paid or 
reported to date. For lines of business with long reporting lags, which include other liability (occurrence), products liability, 
excess workers’ compensation and liability reinsurance, the key assumption is the expected loss ratio since there is often little 
paid or incurred loss data to consider. Historically, the Company has experienced less variation from its initial loss estimates for 
lines of businesses with short reporting lags than for lines of business with long reporting lags.

The key assumptions used in calculating the most recent estimate of the loss reserves are reviewed each quarter and 

adjusted, to the extent necessary, to reflect the latest reported loss data, current trends and other factors observed. 

A claim may be defined as an event, as a claimant (number of parties claiming damages from an event) or by exposure 

type (e.g., an event may give rise to two parties, each claiming loss for bodily injury and property damage). 

86

The most commonly used claim count method is by event. Most of the Company's businesses use the number of events 

to define and quantify the number of claims. However, in certain lines of business, where it is common for multiple parties to 
claim damages arising from a single event, a business may quantify claims on the basis of the number of separate parties 
involved in an event. This may be the case with businesses writing substantial auto or transportation exposure.

Claim counts for assumed reinsurance will vary based on whether the business is written on a facultative or treaty 

basis. Further variability as respects treaty claim counts may be reflective of the nature of the treaty, line of business coverage, 
and type of participation such as quota share or excess of loss contracts. Accordingly, the claim counts have been excluded 
from the below Reinsurance & Monoline Excess segment tables due to this variability.

The claim count information set forth in the tables presented below may not provide an accurate reflection of ultimate 

loss payouts by product line.

The following tables present undiscounted incurred and paid claims development as of December 31, 2023, net of 

reinsurance, as well as cumulative claim frequency and the total of incurred but not reported liabilities (IBNR). The information 
about incurred and paid claims development for the years ended December 31, 2014 to 2022 is presented as supplementary 
information. To enhance the comparability of the loss development data, the Company has removed the impact of foreign 
exchange rate movements by using the December 31, 2023 exchange rate for all periods.

_______________________________________
(1) Claims occurring during the current year are net of loss reserve discounts of $47 million, $35 million and $21 million in 

2023, 2022, and 2021, respectively.

(2) The change in estimates for claims occurring in prior years is net of loss reserve discount. On an undiscounted basis, the 
estimates for claims occurring in prior years decreased by $13 million in 2023, increased by $16 million in 2022, and 
decreased by $19 million in 2021.

(3) For certain retrospectively rated insurance polices and reinsurance agreements, changes in loss and loss expenses for prior 

years are offset by additional or return premiums. 

The COVID-19 global pandemic impacted, and may further impact, the Company’s loss costs. Accordingly, the 

ultimate net impact of COVID-19 on the Company’s reserves remains uncertain. As of December 31, 2023, the Company had 
recognized losses for COVID-19-related claims activity, net of reinsurance, of approximately $384 million, of which 
$326 million relates to the Insurance segment and $58 million relates to the Reinsurance & Monoline Excess segment. Such 
$384 million of COVID-19-related losses included $381 million of reported losses and $3 million of IBNR. For the year ended 
December 31, 2023, the Company recognized current accident year losses for COVID-19-related claims activity, net of 
reinsurance, of approximately $1 million, all of which relates to the Insurance segment.

Unfavorable prior year development (net of additional and return premiums) was $19 million in 2023.

Insurance – Reserves for the Insurance segment developed unfavorably by $24 million in 2023 (net of additional and 
return premiums). The unfavorable development for the segment was concentrated in the early part of the year, with reserve 
development being flat overall during the second half of 2023. A key driver of the unfavorable development early in 2023 was 
property catastrophe losses related to 2022 events which were still being adjusted and settled during the early part of 2023. In 
particular, losses related to U.S. winter storms which occurred during the month of December 2022 were a significant 
contributor to the development, as information gathering and evaluation of many of these claims were still ongoing into the new 
year.

In addition to the property prior year development discussed above, during 2023 the Insurance segment also experienced 

adverse prior year development on casualty lines of business for the 2016 through 2019 accident years, which was offset by 
favorable prior year development on casualty lines of business for the 2020 through 2022 accident years. The unfavorable 
development on the 2016 through 2019 accident years was concentrated in the general liability and commercial auto liability 

98

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
lines of business. The development, which particularly impacted business attaching excess of primary policy limits, was driven 
by a larger than expected number of large losses reported. The Company believes social inflation is contributing to an increase 
in the frequency of large losses for these accident years. Social inflation can include higher settlement demands from plaintiffs, 
use of tactics such as litigation funding by the plaintiffs’ bar, negative public sentiment towards large businesses and 
corporations, and erosion of tort reforms, among others.

The favorable prior year development on casualty lines for the 2020 through 2022 accident years in the Insurance 
segment was concentrated in the professional liability, workers’ compensation, and general liability lines of business. Due to 
elevated uncertainty regarding incurred loss frequency and severity as a result of ongoing social inflation and the impacts of the 
COVID-19 pandemic, the Company set its initial loss ratios for the 2020 through 2022 accident years prudently, and largely 
maintained these estimates through the end of each respective accident year. The reported loss experience to date for these lines 
of business for the 2020 through 2022 accident years has been significantly better than was expected, and the Company has 
begun to react to this favorable emergence as the accident years mature beyond the age of twelve months. It should also be 
noted that commercial auto liability experienced adverse prior year development for the 2020 through 2022 accident years, 
which partially offset the favorable development discussed above; the adverse development was driven by a larger than 
expected number of large losses reported.  

Reinsurance & Monoline Excess – Reserves for the Reinsurance & Monoline Excess segment developed favorably by 
$5 million in 2023 (net of additional and return premiums). The overall favorable prior year development for the segment was 
driven mainly by favorable development in excess workers’ compensation, substantially offset by unfavorable development in 
the non-proportional reinsurance assumed liability and excess general liability (including umbrella) lines of business. The 
favorable excess workers’ compensation development was driven by continued lower claim frequency and reported losses 
relative to our expectations, and to favorable claim settlements. The favorable development was spread across many prior 
accident years. The unfavorable development for non-proportional reinsurance assumed liability and excess general liability 
was associated primarily with our U.S. assumed reinsurance business, and related to accounts reinsuring excess and umbrella 
business and construction projects. The adverse development was concentrated mainly in accident years 2017 through 2020. 

Unfavorable prior year development (net of additional and return premiums) was $36 million in 2022.

Insurance – Reserves for the Insurance segment developed unfavorably by $40 million in 2022 (net of additional and 
return premiums). The unfavorable development in the segment primarily related to COVID-19 losses at two businesses. These 
businesses wrote policies providing coverage for event cancellation and film production delay which were heavily impacted by 
losses directly caused by the COVID-19 pandemic. Most of this COVID-19 related unfavorable development emerged during 
the third quarter as a result of settlements of claims at values higher than our expectations. However, the Company believes that 
as a result of these settlements the remaining level of uncertainty around the ultimate value of its known COVID-19 claims has 
been significantly reduced.

The unfavorable development mentioned above also includes favorable prior year development for the Insurance 

segment primarily attributable to the 2020 and 2021 accident years and unfavorable development on the 2015 through 2019 
accident years. The favorable development on the 2020 and 2021 accident years was concentrated in certain casualty lines of 
business including general liability, professional liability, and workers’ compensation. The Company experienced lower 
reported claim frequency in these lines of business during 2020 and 2021 relative to historical averages, and continued to 
experience lower reported incurred losses relative to its expectations for these accident years as they developed during 2022. 
These trends began in 2020 and we believe were caused by the impacts of the COVID-19 pandemic, including for example, 
lockdowns, reduced driving/traffic and increased work from home. Due to the uncertainty regarding the ultimate impacts of the 
pandemic on accident years 2020 and 2021 incurred losses, the Company was cautious in reacting to these lower trends in 
setting and updating its loss ratio estimates for these years. As these accident years have continued to mature, the Company has 
continued to recognize some of the favorable reported experience in its ultimate loss estimates made during 2022.  

The unfavorable development on the 2015 through 2019 accident years was concentrated in the general liability and 
professional liability, including medical professional, lines of business, as well as auto liability. The development was driven by 
a larger than expected number of large losses reported. The Company believes social inflation is contributing to an increase in 
the frequency of large losses for these accident years. Social inflation can include higher settlement demands from plaintiffs, 
use of tactics such as litigation funding by the plaintiffs’ bar, negative public sentiment towards large businesses and 
corporations, and erosion of tort reforms, among others.

Reinsurance & Monoline Excess – Reserves for the Reinsurance & Monoline Excess segment developed favorably by 

$4 million in 2022 (net of additional and return premiums). The overall favorable development for the segment was driven 
mainly by favorable development in excess workers compensation, substantially offset by unfavorable development in the 

99

professional liability and non-proportional reinsurance assumed liability lines of business. The favorable excess workers’ 
compensation development was spread across most prior accident years, including 2012 and prior years, and was driven by a 
review of the Company’s claim reporting patterns as well as a number of favorable claim settlements relative to expectations. 
The unfavorable professional liability and non-proportional reinsurance assumed liability development was concentrated mainly 
in accident years 2016 through 2018 and was associated primarily with our U.S. assumed reinsurance business and related to 
accounts insuring construction projects and professional liability exposures.

Favorable prior year development (net of additional and return premiums) was $7 million in 2021.

Insurance – Reserves for the Insurance segment developed favorably by $20 million in 2021 (net of additional and return 

premiums).  The overall favorable development in 2021 was attributable to favorable development on the 2020 accident year, 
partially offset by adverse development on the 2016 through 2019 accident years.

The favorable development on the 2020 accident year was largely concentrated in the auto liability and other liability 

lines of business, including commercial multi-peril liability. During 2020 the Company achieved larger rate increases in these 
lines of business than were contemplated in its budget and in its initial loss ratio selections. The Company also experienced 
significantly lower reported claim frequency in these lines in 2020 relative to historical averages, and lower reported incurred 
losses relative to its expectations. We believe that the lower claim frequency and lower reported incurred losses were caused by 
the impacts of the COVID-19 pandemic, for example, lockdowns, reduced driving and traffic, work from home, and court 
closures. However, due to the uncertainty regarding the ultimate impacts of the pandemic on accident year 2020 incurred losses, 
the Company elected not to react to these lower reported trends during 2020. As more information became available and the 
2020 accident year continued to mature, during 2021 the Company started to recognize favorable accident year 2020 
development in response to the continuing favorable reported loss experience relative to its expectations.  

The adverse development on the 2016 through 2019 accident years is concentrated largely in the other liability line of 

business, including commercial multi-peril liability, but is also seen to a lesser extent in Auto liability. The adverse 
development for these accident years is driven by a higher than expected number of large losses reported, and particularly 
impacted the directors and officers liability, lawyers professional liability, and excess and surplus lines casualty classes of 
business. We also believe that increased social inflation is contributing to the increased number of large losses, for example, 
higher jury awards on cases which go to trial, and the corresponding higher demands from plaintiffs and higher values required 
to reach settlement on cases which do not go to trial.

Reinsurance & Monoline Excess – Reserves for the Reinsurance & Monoline Excess segment developed unfavorably by 

$13 million in 2021. The unfavorable development in the segment was driven by the non-proportional reinsurance assumed 
liability and other liability lines of business, related primarily to accident years 2017 through 2019, and was partially offset by 
favorable development in excess workers’ compensation business which was spread across many prior accident years. The 
unfavorable non-proportional reinsurance assumed liability and other liability development was associated with our U.S. and 
U.K. assumed reinsurance business, and related primarily to accounts insuring construction projects and professional liability 
exposures.

Environmental and Asbestos — To date, known environmental and asbestos claims have not had a material impact on 

the Company’s operations, because its subsidiaries generally did not insure large industrial companies that are subject to 
significant environmental or asbestos exposures prior to 1986 when an absolute exclusion was incorporated into standard policy 
language.

The Company’s net reserves for losses and loss expenses relating to asbestos and environmental claims on policies 

written before adoption of the absolute exclusion was $17 million and $20 million at December 31, 2023 and 2022, 
respectively. The estimation of these liabilities is subject to significantly greater than normal variation and uncertainty because 
it is difficult to make an actuarial estimate of these liabilities due to the absence of a generally accepted actuarial methodology 
for these exposures and the potential effect of significant unresolved legal matters, including coverage issues, as well as the cost 
of litigating the legal issues. Additionally, the determination of ultimate damages and the final allocation of such damages to 
financially responsible parties are highly uncertain.

Discounting — The Company discounts its liabilities for certain workers’ compensation reserves. The amount of 
workers’ compensation reserves that were discounted was $1,352 million and $1,464 million at December 31, 2023 and 2022, 
respectively. The aggregate net discount for those reserves, after reflecting the effects of ceded reinsurance, was $390 million 
and $416 million at December 31, 2023 and 2022, respectively. At December 31, 2023, discount rates by year ranged from 
0.7% to 6.5%, with a weighted average discount rate of 3.5%.

Substantially all discounted workers’ compensation reserves (97% of total discounted reserves at December 31, 2023) 

are excess workers’ compensation reserves. In order to properly match loss expenses with income earned on investment 

100

securities supporting the liabilities, reserves for excess workers’ compensation business are discounted using risk-free discount 
rates determined by reference to the U.S. Treasury yield curve. These rates are determined annually based on the weighted 
average rate for the period. Once established, no adjustments are made to the discount rate for that period, and any increases or 
decreases in loss reserves in subsequent years are discounted at the same rate, without regard to when any such adjustments are 
recognized. The expected loss and loss expense payout patterns subject to discounting are derived from the Company’s loss 
payout experience. 

The Company also discounts reserves for certain other long-duration workers’ compensation reserves (representing 
approximately 3% of total discounted reserves at December 31, 2023), including reserves for quota share reinsurance and 
reserves related to losses regarding occupational lung disease. These reserves are discounted at statutory rates prescribed or 
permitted by the Department of Insurance of the State of Delaware.

(14)  Premiums and Reinsurance Related Information 

The Company reinsures a portion of its insurance exposures in order to reduce its net liability on individual risks and 
catastrophe losses. Reinsurance coverage and retentions vary depending on the line of business, location of the risk and nature 
of loss. The Company’s reinsurance purchases include the following: property reinsurance treaties that reduce exposure to large 
individual property losses and catastrophe events; casualty reinsurance treaties that reduce its exposure to large individual 
casualty losses, workers’ compensation catastrophe losses and casualty losses involving multiple claimants or insureds; and 
facultative reinsurance that reduces exposure on individual policies or risks for losses that exceed treaty reinsurance capacity. 
Depending on the business, the Company purchases specific additional reinsurance to supplement the above programs.

(1) Many states require licensed insurers that provide workers' compensation insurance to participate in programs that provide 
workers' compensation to employers that cannot procure coverage from an insurer on a voluntary basis. Insurers can fulfill 
this residual market obligation by participating in pools where results are shared by the participating companies. The 
Company acts as a servicing carrier for workers' compensation pools in certain states. As a servicing carrier, the Company 
writes residual market business directly and then cedes 100% of this business to the respective pool. As a servicing carrier, 
the Company receives fee income for its services. The Company does not retain underwriting risk, and credit risk is limited 
as ceded balances are jointly shared by all the pool members.

(1) Subsidiary debt of $6 million is due in 2024, partially offset by the unamortized cost of $0.6 million due to entering into the 
$300 million senior unsecured revolving credit facility. 

On April 1, 2022, the Company entered into a senior unsecured revolving credit facility that provides for revolving, 

unsecured borrowings up to an aggregate of $300 million with a $50 million sublimit for letters of credit. The Company may 
increase the amount available under the facility to a maximum of $500 million subject to obtaining lender commitments for the 
increase and other customary conditions. Borrowings under the facility may be used for working capital and other general 
corporate purposes. All borrowings under the facility must be repaid by April 1, 2027, except that letters of credit outstanding 
on that date may remain outstanding until April 1, 2028 (or such later date approved by all lenders). Our ability to utilize the 
facility is conditioned on the satisfaction of representations, warranties and covenants that are customary for facilities of this 
type. As of December 31, 2023, there were no borrowings outstanding under the facility.

The Company had a net current tax payable of $46 million and a net tax receivable of $5 million at December 31, 2023 

and 2022, respectively. At December 31, 2023, the Company had foreign net operating loss carryforwards of $220 million that 
have no expiration date. At December 31, 2023, the Company had a valuation allowance of $36 million as compared to $47 
million at December 31, 2022. The Company has provided a valuation allowance against the utilization of foreign tax credits 
and the future net operating loss carryforward benefits of certain foreign operations. The statute of limitations for the 
Company’s U.S. Federal income tax returns has closed for all years through December 31, 2019.

The realization of the deferred tax asset is dependent upon the Company’s ability to generate sufficient taxable income 

in future periods. Based on historical results and the prospects for future current operations, management anticipates that it is 
more likely than not that future taxable income will be sufficient for the realization of this asset.

The Tax Cuts and Jobs Act of 2017 (the "Tax Act") provided for a reduction of the U.S. corporate income tax rate 
from 35% to 21% effective January 1, 2018. The U.S. tax law requires insurance reserves to be discounted for tax purposes. 
The Tax Act modified this computation. The IRS issued revised discount factors to be applied to the 2017 reserves, which 
increased the beginning of year 2018 deferred tax asset for loss reserve discounting. Under the related transition rule, a deferred 
tax liability was established which will be included in taxable income over the eight year period that began in 2018.  

The Company has not provided U.S. deferred income taxes on the undistributed earnings of approximately 

$261 million of its non-U.S. subsidiaries since these earnings are intended to be permanently reinvested in the non-U.S. 
subsidiaries. In the future, if such earnings were distributed the Company projects that the incremental tax, if any, will be 
immaterial.

(17)  Dividends from Subsidiaries and Statutory Financial Information

The Company’s insurance subsidiaries are restricted by law as to the amount of dividends they may pay without the 

approval of regulatory authorities. The Company’s lead insurer, Berkley Insurance Company ("BIC"), directly or indirectly 
owns all of the Company’s other insurance companies. During 2024, the maximum amount of dividends that can be paid by 
BIC without such approval is approximately $1.2 billion. 

BIC’s combined net income and statutory capital and surplus, as determined in accordance with statutory accounting 

practices ("SAP"), are as follows:

$  8,776,138  $  8,330,587  $  6,817,535 

The significant variances between SAP and GAAP are that for statutory purposes bonds are carried at amortized cost, 

unrealized gains and losses on equity securities are recorded in surplus, acquisition costs are charged to income as incurred, 
deferred Federal income taxes are subject to limitations, excess and assumed workers’ compensation reserves are discounted at 
different discount rates and certain assets designated as “non-admitted assets” are charged against surplus. The Commissioner 
of Insurance of the State of Delaware has allowed BIC to recognize a non-tabular discount on certain workers' compensation 
loss reserves, which is a permitted practice that differs from SAP. The effect of using this permitted practice was an increase to 
BIC’s statutory capital and surplus by $159 million at December 31, 2023.

The National Association of Insurance Commissioners (“NAIC”) has risk-based capital (“RBC”) requirements that 
require insurance companies to calculate and report information under a risk-based formula which measures statutory capital 
and surplus needs based on a regulatory definition of risk in a company’s mix of products and its balance sheet. This guidance 
is used to calculate two capital measurements: Total Adjusted Capital and RBC Authorized Control Level. Total Adjusted 
Capital is equal to the Company’s statutory capital and surplus excluding capital and surplus derived from the use of permitted 
practices that differ from statutory accounting practices. RBC Authorized Control Level is the capital level used by regulatory 
authorities to determine whether remedial action is required. Generally, no remedial action is required if Total Adjusted Capital 
is 200% or more of the RBC Authorized Control Level. At December 31, 2023, BIC’s Total Adjusted Capital of $8.6 billion 
was 391% of its RBC Authorized Control Level.

Treasury shares have been excluded from average outstanding shares from the date of acquisition. The weighted 
average number of basic shares outstanding includes the impact of 11,663,450 common shares held in a grantor trust. The 
common shares held in the grantor trust are for delivery upon settlement of vested but mandatorily deferred restricted stock 
units ("RSUs"). Shares held by the grantor trust do not affect diluted shares outstanding since shares deliverable under vested 
RSUs were already included in diluted shares outstanding. The difference in calculating basic and diluted net income per share 
is attributable entirely to the dilutive effect of stock-based compensation plans. Changes in shares of common stock 
outstanding, net of treasury shares, are presented below. Shares of common stock issued and outstanding do not include shares 
related to unissued restricted stock units (including shares held in the grantor trust).

results of operations, cash flow, financial condition and business needs, the capital and surplus requirements of our subsidiaries, 
and applicable insurance regulations that limit the amount of dividends that may be paid by our regulated insurance 
subsidiaries.

The estimated fair values of the Company’s fixed maturity securities, equity securities available for sale and arbitrage 
trading account securities are based on various valuation techniques that rely on fair value measurements as described in Note 
12 above. The fair value of loans receivable is estimated by using current institutional purchaser yield requirements for loans 
with similar credit characteristics, which is considered a Level 2 input. The fair value of the senior notes and other debt and the 
subordinated debentures is based on spreads for similar securities, which is considered a Level 2 input.

(20)  Commitments, Litigation and Contingent Liabilities 

In the ordinary course of business, the Company is subject to disputes, litigation and arbitration arising from its 

insurance and reinsurance businesses. These matters are generally related to insurance and reinsurance claims and are 
considered in the establishment of loss and loss expense reserves. In addition, the Company may also become involved in legal 
actions which seek extra-contractual damages, punitive damages or penalties, including claims alleging bad faith in handling of 
insurance claims. The Company expects its ultimate liability with respect to such matters will not be material to its financial 
condition. However, adverse outcomes on such matters are possible, from time to time, and could be material to the Company’s 
results of operations in any particular financial reporting period.

On December 22, 2023, one of the Company’s subsidiaries filed a lawsuit against certain reinsurers to recover in excess 

of $90 million in respect of certain losses paid to its policyholders under certain event cancellation and related insurance 
policies. The Company believes its claims against the reinsurers are meritorious and expects a positive resolution to its lawsuit. 
While an adverse outcome is possible, the Company believes that the outcome, in any case, will not be material to the 
Company’s financial condition.

At December 31, 2023, the Company had commitments to invest up to $339 million and $106 million in certain 

investment funds and real estate construction projects, respectively.

(21) Leases

Lessees are required to recognize a right-of-use asset and a lease liability for leases with terms of more than 12 months 

on the balance sheet. All leases disclosed within this note are classified as operating leases. Recognized right-of-use asset and 
lease liability are reported within other assets and other liabilities, respectively, in the consolidated balance sheet. Lease 
expense is reported in other operating costs and expenses in the consolidated statement of income and accounted for on a 
straight-line basis over the lease term.

To determine the discount rate used to calculate present value of future minimum lease payments, the Company uses 

its incremental borrowing rate during the lease commencement period in line with the respective lease duration. In certain 
cases, the Company has the option to renew the lease. Lease renewal future payments are included in the present value of the 
future minimum lease payments when the Company determines it is reasonably certain to renew. 

The main leases entered into by the Company are for office space used by the Company’s operating units across the 
world. Additionally, the Company, to a lesser extent, has equipment leases mainly for office equipment. Further information 
relating to operating lease expense and other operating lease information is as follows:

Pursuant to the Company's stock incentive plan, the Company may issue restricted stock units ("RSUs") to employees 

of the Company and its subsidiaries. The RSUs generally vest three to five years from the award date and are subject to other 
vesting and forfeiture provisions contained in the award agreement. The following table summarizes RSU information for the

Upon vesting, shares of the Company’s common stock equal to the number of vested RSUs are issued or deferred to a 

later date, depending on the terms of the specific award agreement. As of December 31, 2023, 11,560,624 RSUs had been 
deferred. RSUs that have not yet vested and vested RSUs that have been deferred are not considered to be issued and 
outstanding shares. 

The fair value of RSUs at the date of grant are recorded as unearned compensation, a component of stockholders’ 

equity, and expensed over the vesting period. Following is a summary of changes in unearned compensation for the three years 
ended December 31, 2023:

(23)  Compensation Plans

The Company and its subsidiaries have profit sharing plans in which substantially all employees participate. The plans 
provide for minimum annual contributions of 5% of eligible compensation; contributions above the minimum are discretionary 
and vary with each participating businesses's profitability. Employees become eligible to participate in the plan on the first day 
of the calendar quarter following the first full calendar quarter after the employee's date of hire provided the employee has 
completed 250 hours of service during the calendar quarter. The plans provide that 40% of the contributions vest immediately 
and that the remaining 60% vest at varying percentages based upon years of service. Profit sharing expense was $75 million, 
$62 million and $50 million in 2023, 2022 and 2021, respectively. 

The Company has a long-term incentive compensation plan ("LTIP") that provides for compensation to key executives 

based on the growth in the Company's book value per share over a five year period.

DISCLOSURE

None.

ITEM 9A. CONTROLS AND PROCEDURES

           The Company's management, including its Chief Executive Officer and Chief Financial Officer, have conducted an 
evaluation of the effectiveness of the Company's disclosure controls and procedures pursuant to Exchange Act Rule 13a-15(b) 
as of the end of the period covered by this annual report. Based on that evaluation, the Chief Executive Officer and Chief 
Financial Officer concluded that the Company has in place effective controls and procedures designed to ensure that 
information required to be disclosed by the Company in the reports it files or submits under the Exchange Act and the rules 
thereunder, is recorded, processed, summarized and reported within the time periods specified in the Commission's rules and 
forms.
           During the quarter ended December 31, 2023, there have been no changes in our internal controls over financial 
reporting that have materially affected, or are reasonably likely to materially affect, our internal controls over financial 
reporting.

Management's Report On Internal Control Over Financial Reporting 

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding 

the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with 
generally accepted accounting principles. A company's internal control over financial reporting includes those policies and 
procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions 
and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to 
permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of the company are 
being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable 
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that 
could have a material effect on the financial statements. 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. 

Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become 
inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. 
Under the supervision and with the participation of our management, including our principal executive officer and principal 
financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the 
framework in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of 
Treadway Commission. Based on our evaluation under the framework in Internal Control - Integrated Framework, our 
management concluded that our internal control over financial reporting was effective as of December 31, 2023.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors
W. R. Berkley Corporation:

Opinion on Internal Control Over Financial Reporting 

We have audited W. R. Berkley Corporation and subsidiaries’ (the Company) internal control over financial reporting as of 
December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee 
of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, 
effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - 
Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the consolidated balance sheets of the Company as of December 31, 2023 and 2022, the related consolidated 
statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-year 
period ended December 31, 2023, and the related notes and financial statement schedules II to VI (collectively, the consolidated 
financial statements), and our report dated February 23, 2024 expressed an unqualified opinion on those consolidated financial 
statements.

Basis for Opinion 

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its 
assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report 
On Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control 
over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be 
independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and 
regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all 
material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control 
over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating 
effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we 
considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting 

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the 
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally 
accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures 
that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit 
preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and 
expenditures of the company are being made only in accordance with authorizations of management and directors of the 
company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or 
disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
