W. R. Berkley Corporation    |    2020 Annual Report

I am convinced that  
life is 10% what happens  
to me and 90% how  
I react to it. And so it  
is with you. 

“ The longer I live, the more I realize the impact of 
attitude on life. Attitude, to me, is more important 
than facts. It is more important than the past, than 
education, than money, than circumstances, than 
failures, than successes, than what other people think 
or say or do. The remarkable thing is we have a choice 
every day regarding the attitude we will embrace for 
that day. We cannot change our past. We cannot 
change the fact that people will act in a certain way.  
We cannot change the inevitable. The only thing we 
can do is play on the one string we have, and that is our 
attitude. I am convinced that life is 10% what happens  
to me and 90% how I react to it. And so it is with you.  
We are in charge of our attitudes.”

 ~ Charles Swindoll

It is our belief that attitude is everything — how one
acts and reacts and the standards one lives up to
are more important to the outcome than what events
may happen in life or business, as exemplified by the
Charles Swindoll quotation. By its nature, property
and casualty insurance is an industry that requires
responsiveness, compassion and a helpful, can-do
attitude. Our business model has fostered personal
responsibility, accountability and doing the right
thing for our stakeholders since the Company was
formed more than 50 years ago. It is the foundation
of our culture that has made us a resilient company,
built for long-term success.

To Our
Shareholders

LEFT TO RIGHT:

W. Robert Berkley, Jr.,
President and Chief Executive Officer

William R. Berkley,
Executive Chairman

2020 was a year unlike one we have
ever experienced; it was unique.
Our Company’s focus on risk-adjusted
return continued, but our efforts for
much of the year centered on the inherent
risks of COVID-19 and how it impacted
our employees, customers and our
enterprise as well as the communities
in which we operate.

We delivered satisfactory economic returns, but
some of our proudest achievements are directly
related to our colleagues’ support of the communi-
ties in which we work. Overnight, almost all of our
enterprise began operating remotely and has con-
tinued to do so. We modified our operating systems
to make the changes seamless and the quality of our
service and delivery of our insurance products did
not miss a beat. The Company was supportive of our
agents and brokers, while helping them deal with this
extraordinary environment. We contributed millions
of dollars to various not-for-profit organizations,
including food banks and medical service providers.
Our employees volunteered within their communi-
ties, providing local support to thousands of people.
We continued to reach out to all of our constituents
during this very difficult time.

The year was also complicated because of the U.S.
Presidential election. This created an increasing
level of anxiety and uncertainty. The political turmoil
had global impact on the world economy and global
trade. In an industry that prospers best with predict-
ability, these levels of uncertainty made operating
more complicated. At the same time, global eco-
nomic policy, which was built on deficit spending and
drove down interest rates, created new risks for
our business. Record low interest rates resulted in
low investment returns and at the same time we
were faced with increased risks of both financial
and social inflation.

The overall environment is clearly the place to start
when examining 2020. The two issues already men-
tioned above caused tremendous adverse impact on
economic activity. Many businesses closed. In-person
business transactions came to a virtual stop; restau-
rants and entertainment still have not reopened
to anything approaching the pre-COVID level. Unem-
ployment levels inclusive of those people who left
the job market are close to 10%. All this has resulted
in enormous government stimulation with the
concomitant government deficits in the trillions
of dollars. The deficits have been exacerbated by

$11.2

the fact that, in this political year, more spending was
the one thing most politicians could agree upon.
$11.7

As we entered the second half of 2020 with vaccines
$12.0
on the horizon, optimism took hold and markets
rebounded. Interest rates continued to stay at record
lows supported by the Federal Reserve and modest
improvements in the business world became visi-
ble. Simultaneously, the housing market began to
rebound substantially, further stimulating economic
activity. The country was not yet doing well, but gen-
erally people were optimistic and those who invested
in the tech side of the equities market were doing
incredibly well. The stock market was at record highs
and interest rates were at record lows.

$12.6

$13.8

The politics of the election became ugly. Questions
were raised about our democratic institutions and
about our democracy itself, further increasing the
overall level of social anxiety and uncertainty. To
some, these questions seemed unwarranted and to
others it was a responsibility of our society to ask
these questions. We are on a better path now that
the vaccine has been distributed to well over 15% of
the U.S. population and the election is resolved.

While dealing with these societal issues, the Company
had to make many adjustments. We activated all of
our plans to operate remotely and within a relatively
short period of time, practically all of our businesses
were operating on a remote basis, delivering our
products and services to all of our agents, brokers
and insureds. Many of our activities required some
modification and clearly these changes tested the
culture of teamwork that is the hallmark of our enter-
prise. We were able to transform our companies to
operate successfully.

The financial results of the business were generally
satisfactory given the circumstances of the year.
Overall investment income was down primarily
because of our shortened duration and declining
interest rates. We made the conscious decision
to shorten our duration, which reduced the risk of
capital loss if interest rates increase in the future,
as we expect.

$6.1

$6.3

Many of our employees did volunteer work for those
less fortunate and frequently we stepped in to provide
specific assistance to some of our agents and brokers
who had special issues in this new virtual environment.

We are incredibly proud of the effort
everyone put forth; not just in helping our
enterprise, but also in helping so many
colleagues get through this difficult time.

We are not yet through the COVID-19 event but we are
well on our way. We have gotten to where we are only

Our private equity and fund investing delivered
excellent returns. Our arbitrage account had its best
year in a decade. In addition, we sold one consequen-
tial real estate investment for a substantial gain.

We continue to evaluate our real estate portfolio
in an opportunistic fashion, and at the same time we
are examining new opportunities in non-traditional
investments that offer higher returns than fixed
income securities. Assessment of risk is critical if
one hopes to be a successful investor. We continue
to seek out opportunities that can provide improved
returns to our shareholders. In this transitional
process, we have substantially increased our liquidity
with over 15% of our portfolio in cash and short-term

securities. We expect, over the next 12 months, to
find improving risk-adjusted returns for much of
these funds.

The cornerstone of our business has
always been outstanding insurance
underwriting results.

17%

We select lines of business that offer opportunities
for above-average profitability. In addition, our risk
selection process, executed by experienced under-
writers, allows us to achieve loss ratios that are more
attractive than the industry average. At the same
time, we focus on delivering outstanding service from
the beginning of the underwriting process right
through and including the handling of claims. The end
result has generally allowed our Company to have
underwriting results well above the industry average.
It is still incumbent upon us to manage the expenses
of running our business at a level where we continue
to be competitive and we must deliver first-quality
service in the most timely fashion.

* Net of $874 million in special dividends and shares repurchased from 2016 to 2020

2020 was not a year where the basics were enough.
Pressure from low interest rates and the need to
raise rates to deal with potential increasing social
inflation and financial inflation required management
not just to pay attention to pricing, but to search for
opportunities to grow in an economy that provided
little growth on its own.

As we worked our way through the
year, we consciously reserved for the
uncertainties that we saw ahead of
us and pushed forward to help assure
that we would be well situated to
capitalize on all the opportunities that
presented themselves in the future.

2020 was not the year we hoped for. Our return on
capital was down substantially, primarily because
investment income declined as a result of lower
interest rates and a shorter-duration portfolio as
well as losses related to COVID-19. We used this
opportunity to carefully prepare our Company for
2021 and the years ahead. We are optimistic about
every aspect of our enterprise. We could not have
gotten through all these difficult times without
the incredible commitment of our employees, the
guidance of our Board, the support of our agents
and brokers, and our ongoing relationships with our
customers. We thank all of them for helping us get
through this challenging time and we look forward to
better years ahead.

We feel we were able to do that in 2020 and we are
prepared to seize the opportunities to improve our
profitability and grow our business.

2020 was a year like no other, characterized by
extreme uncertainty and unpredictability. It demanded
responsiveness, resiliency, flexibility and innovative
thinking. Our team rose to the challenge by delivering
uninterrupted service and going above and beyond
to help others in the face of difficult circumstances.
At the same time, we continued to address the
emerging needs of our clients in the ever-changing
world of risk. This annual report highlights the way
in which our Company and our employees support four
key stakeholder groups — our clients, our distribution
partners, our people and our communities — and by
extension, our shareholders.

Insurance done right by a company of people who care.

Serving
Our Clients

“Insurance is a promise.
Being there when it counts
in good times and in bad —
to help prevent losses and
respond to them when they
do occur — engenders the
trust of our customers.”

Property and casualty insurance is critical to the functioning
of modern society and the overall economy. Consequently,
the industry plays a pivotal role in supporting and advancing
the world’s evolving needs for products and services that help
manage risk and, in turn, allow clients to deliver their products
and services to the consumer. Our disciplined underwriting
and deep expertise allow us to remain a consistent and stable
market in our selected businesses throughout the insurance
cycle and under all conditions. Berkley supports its clients by

SERVING  OUR CLIENTS

Created by rahmat

Providing a Market

Insurance for
COVID-19 Vaccine

Created by Vectors Point
from the Noun Project

Being Prepared with
Cyber Insurance

Through Berkley Life Sciences, we offer liability coverage
to a range of companies, from those with products in the
preclinical stage to Fortune 1000 companies with numer-
ous products on the market, including some of the leading
producers of COVID-19 vaccines. At a time when fewer
competitors are offering limits for such risks, this coverage
enables pharmaceutical companies to manufacture and
distribute their products to people around the world. The
vaccines, in turn, can protect inoculated individuals and
those around them from COVID-19, thereby reducing the
spread of the virus and facilitating the reopening of society.

“We work with companies involved in the life
sciences area. These are the companies that
change the lives of people every day.”

The risk of cyber attack, data breach or data theft is one
of the fastest-growing and most uncertain emerging risks
that businesses and individuals face today. Our leading
industry experts in the field understand that merely
providing coverage in the event of a loss is not sufficient
for a risk that carries the potential for unknown and
widespread impacts. Pre- and post-breach services that
support prevention and preparedness as well as recovery
after an event are critical to helping clients manage their
risk. All of our operating units take a proactive view of
managing their exposure to losses from cyber events, and
a select number of them offer their clients coverage, advice
and access to resources. Berkley Cyber Risk’s singular
focus on cyber as a peril allows us to constantly refine and
update new coverage options for emerging cyber risks
and trends and to be responsive to client-specific coverage
and service needs. As a reinsurance provider, Berkley Re
Solutions offers turnkey products for clients that provide
insurance and services to small businesses, individuals
and families, and farm owners.

The average
cost of a
data breach in
2020 was:

$3.86M

According to a report from IBM and the Ponemon Institute

“Boards of directors cannot pay lip service to cyber
risk anymore. They need to understand that a
cyber breach may not only be a reputational damage
crisis situation; it can also have material financial
consequences, no matter the size of the company.”

Supporting Healthcare
Organizations and
Their Workers

Created by mynamepong
from the Noun Project

Focusing on
Better Outcomes for
Injured Workers

The healthcare industry is rapidly evolving, shaped by
emerging concepts in science, technology, law, public
welfare and social economics. The COVID-19 pandemic
added a tremendous level of additional complexity to
insuring healthcare providers and their workers in 2020
and beyond, causing certain insurance providers to
withdraw from the market. In 2020, we increased our
commitment to the healthcare industry by introducing new
products and services, such as a suite of products to cover
non-emergency medical transportation providers. Through
our operating units, we apply innovative insurance con-
cepts to traditional healthcare insurance and provide a
wide range of coverages, including professional liability,
general liability, commercial auto, financial lines, workers’
compensation, and accident and health, to a broad spec-
trum of healthcare and related businesses. Our products
and services are designed to address the current complex-
ity of the healthcare industry and provide flexibility to our
clients in managing enterprise risk.

At Berkley, we invest in better solutions to achieve better
outcomes. Better outcomes in workers’ compensation
cases mean more than just saving money on a claim for the
insured employer. They mean finding the right care for
injured workers that gets them healthy enough to get back
on their feet and back to work, or in the case of a cata-
strophic injury, to the best possible quality of life. Through
the use of early-severity predictive models that enable
early-care intervention, nurse case managers, pharmacy
bill managers, injured employee portals and injured
employee return-to-work programs, we work with our
clients to improve outcomes when injuries occur. As
importantly, our educational safety and loss-control
programs can help insureds improve health and safety
protocols to reduce the incidence of injury to their
employees. We believe people should be safe at work,
accidents are preventable, and people deserve excep-
tional care and compassion. When an accident does occur,
responsiveness makes a difference.

• Healthcare is the fastest-growing sector of the

U.S. economy, employing over 18 million workers.

Source: CDC

“One of the things that I think I really value is the
fact that, from a claims standpoint, they are truly
concerned about the well-being of the injured
employee and that is kind of invaluable. We feel like
we have created a better program, better coverage,
better pricing and better service.”

Supporting
Our Distribution
Partners

“Having the right partners
has been incredibly impactful
on our business. We continue
to believe that expertise
combined with capital,
delivered with good advice,
is the best way to deliver
value to most customers.”

Our agents, brokers and other distribution systems have been
long-term partners in our success in delivering traditional
and innovative products and services to our clients. Berkley
supports its distribution partners in meeting the day-to-day
challenges that arise in the course of doing business, both big
and small, and in enhancing their relationships with clients.
Ongoing education and training for our distribution partners
on emerging risks and new products and services aids in the
development of their businesses and their people, ultimately
improving the customer experience. We actively support the
development of the next generation of insurance agents
and brokers, and look for opportunities to enhance their value
proposition as technology and direct distribution models
threaten the status quo.

Supporting Our
Distribution Partners
in Times of Crisis

Connecting Virtually

When disaster strikes, no one is immune. Despite careful
and extensive disaster recovery planning, things can
and do sometimes go awry. We recognize the importance
of supporting our trusted partners, particularly when
they need it most. As the world shut down in early 2020
and some of our distribution partners were themselves
impacted, we were able to step in to fill the gaps. Just as
our insureds rely on us to meet our obligations, they
rely on their agents or brokers to help them navigate the
insurance process. Our distribution partners know they
can count on us, and when contingency plans or technol-
ogy failed, we pitched in to handle critical details and
essential tasks, freeing them up to address what went
wrong, while continuing to offer advice and service to their
clients. Today, most have sufficient hardware — laptops
and mobile devices — and remote connectivity systems
are standing up. We continue to work side by side with
our distribution partners through this crisis and beyond.

Developing strong connections with our distribution
partners is an important component of relationship
building and servicing our clients. Stay-at-home policies
implemented across the globe during the COVID-19
pandemic necessitated a rapid transition to virtual engage-
ment. While video meetings and phone calls became the
norm, we went a step further to offer agents innovative
technology to better serve and engage their clients, includ-
ing the use of artificial intelligence to perform virtual
underwriting inspections and drones for claims inspec-
tions. In addition, we introduced the Berkley Concert
Series as a way for Berkley distribution partners to connect
with clients in a fun way while maintaining social distance.
Agents, brokers and clients were invited to participate in
virtual concerts featuring popular artists. Operating units
and producers in turn designed their own virtual events
around the concert, creating further touchpoints during
the pandemic. The artists were not revealed until the concert
began, increasing the level of excitement as invitees
speculated on who it would be. And they were not disap-
pointed! Attendees were treated to amazing performances
by Train, Matchbox Twenty and Christina Aguilera.

Nearly

6,000 people virtually

attended each
concert

Supporting Agents and
Brokers Through Education
and Development

Supporting our distribution partners through participa-
tion in industry trade associations, including education
and the development of the next generation of agents and
brokers, has engendered their trust and been an important
contributor to our long-term success. We participate in
organizations that provide education, development and
networking resources to various professional or business
segment groups, such as The Institutes, the Casualty
Actuarial Society and the Wholesale Specialty Insurance
Association, among many others. In addition, Berkley
is a Council Partner of the Council of Insurance Agents &
Brokers (CIAB), supports the Independent Insurance
Agents & Brokers of America, Inc. (The Big “I”) and is a
Trusted Choice® Member. We are also a sponsor of
the Young Agents program of the “The Big I,” which provides
education, networking and community for young insurance
professionals and newer agency and brokerage owners.
It hosts the Young Agents Leadership Institute, which
provides training in sales and leadership, and hosts an
annual summit for its members.

“Young agents are well on their way to
successful, lifelong careers as Trusted Choice
independent insurance agents.”

Empowering
Our People

“Together, we bring the collective
power of diverse ideas and
skills. Everyone has the power
to make a difference.”

Our people are our greatest asset and our corporate culture
is the most important intangible value driver of our superior
long-term risk-adjusted returns and growth in stockholder
value. We empower our people to lead, to be accountable and
to thrive. We work nimbly, energized by a business structure
that brings proactive decision making to the local level —
localized with global resources. We are focused on creating a
respectful, rewarding, diverse and inclusive work environment
that allows our employees to build meaningful 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 profes-
sionals through training and engagement, as well as in their
well-being through robust health and wellness programs
and a commitment to diversity.

EMP OWERI NG OUR PEOPLE

Engaging Our People
Throughout Our Work-
from-Home Journey

As it became apparent in the spring of 2020 that shut-
downs and social distancing would become the status quo
for the foreseeable future, we recognized that our current
initiatives that focused on employee health, safety and
productivity would not be enough to support our employ-
ees through these difficult and uncertain times and
maintain our culture. In addition to providing access to
emotional and mental well-being resources, we took further
steps to keep our employees engaged and connected
while maintaining our social distance. Among other things,
the human resources team developed a monthly flip-book
newsletter entitled Berkley’s Work from Home Journey,
journaling some of the creative and entertaining ways
individuals and their families are working, laughing, staying

fit and getting closer to one another, all while continuing
to physically distance. We celebrated holidays and
milestones, recognized frontline workers, volunteers and
the unsung heroes of IT who keep us all going, and pro-
moted our Innovation Through People initiative. We shared
the challenges of working from home, targeting those who
were trying to balance work with caring for children who
were experiencing new ways of learning, and soon learned
that those living alone who may have relied on their work-
place as a means of social interaction had their own unique
issues. Engagement has been high, with scores of colleagues
sharing their stories and the majority of our employees
reading each issue of the newsletter. We are reminded that
at Berkley, Everything Counts, Everyone Matters.®

“Thank you to all of you for sharing with us these
kind, supportive, creative and fun moments.
I am so grateful and proud to be on your team!”

• More than 3,000 employees read our flip-book

each month.

Fostering an
Innovative Mindset

Created by corpus delicti
from the Noun Project

Nurturing Our
Entrepreneurial
Spirit

We pursue innovation in a classically Berkley way —
with an emphasis on the contribution of every individual
employee. In 2017, we embarked on an ongoing innovation
journey that engages all employees and has a foundation
in the development of behaviors that foster an innovative
mindset to build upon our entrepreneurial culture and
roots. We have created a dedicated Innovation Through
People brand for innovation at Berkley, along with an
internal education and awareness campaign to deepen
employee engagement in this important pillar of our
organization. We have also built an online curriculum and
resource library to ensure the framework’s sustainability
and upgraded our tool for company-wide idea engage-
ment. The program is championed and supported at the
corporate level, while each operating unit has been tasked
with building its own framework for supporting our
innovation behaviors and building the processes neces-
sary to sustain an innovative practice and culture using
these tools. In 2021, we are focused on reframing our view
of failure to see it as a learning experience. To date, we
have tracked 13,139 innovative ideas, with 436 approved
for experimentation, 416 approved for implementation
and 739 implemented.

“Behavioral learning is so important to the
execution of ideas. You can’t skip culture and
go straight to the new process.”

Berkley’s long-standing tradition of empowering our
people and supporting them as they develop new ways to
serve our customers is deeply rooted in our entrepreneur-
ial culture and history. As an organization founded with a
mere $2,500 that has grown to over $8 billion in annual
revenue by founding 46 of our 53 operating units, we know
that good ideas need to be nurtured. In 2020, the team at
Berkley One piloted a new way to increase their new
business hit ratio. They recognized that abandoned quote
quality was high and that engaging with agents in real time
to help them improve the quotes was key to success.
So they set out to learn how to triage those abandoned
quotes to find the ones with the best potential for conver-
sion. An outstanding performer from its customer service
team was moved to the sales team and provided the
autonomy to work on this experiment full-time, using the
powerful information in Berkley One’s database to target
engagement with high precision. Berkley One’s agents
began thinking of the sales team as “guardian angels”
because of the speed and accuracy of their engagement,
which enabled them to efficiently close on a greater
percentage of new accounts. They then built a model that
optimizes the process by informing sales associates which
submissions they should engage on and the reason why
they should call to proactively engage. The project team is
now taking their show on the virtual road to share their
learnings with other Berkley operating units.

• 30% more accounts reviewed per month

• 44% less time reviewing submissions

•

106% increased new business production in
the first month

Serving
Our Communities

“We exist as part of a greater
society and have always
believed in being supportive of
the communities that we are
part of, because in the long
run, our enterprise and all of
its stakeholders benefit.”

The culture of a successful business enterprise requires
many things. Among the most important elements is a
committed workforce — people who share a vision, not just
for the business’s operating objectives, but also for how it
serves its clients and where it fits into society. W. R. Berkley
Corporation’s long-standing traditions of community
involvement set the foundation for supporting people where
we live and work as we seek to enhance the human experi-
ence through donations of our time and resources. W. R.
Berkley Corporation and its operating units participate in
various national and global campaigns and support many
local nonprofit organizations in an effort to ensure tangible,
effective impacts from our contributions. The increased
challenges to all communities from the COVID-19 pandemic
have further spotlighted the importance of being an
engaged and responsible corporate citizen.

The Company’s operating units have not only provided
financial support, but also organized volunteer efforts for
community organizations within their local communities
or for causes important to their business or a team
member. Combating food insecurity, providing children’s
assistance, healthcare, and diversity and inclusion are
common themes for volunteer efforts throughout the
organization. Near and dear to our hearts is helping
individuals impacted by the things we see in our everyday
business. For example, Kids’ Chance, which supports
children affected by a parent’s work-related injury or death
by helping to remove financial obstacles to pursuing their
educational dreams, has a direct connection to our
business. Going beyond annual donations, several of our
operating units host or participate in dedicated fundraising
events for the organization and many of our employees
hold leadership roles at the national level or at local
chapters. Additionally, in the shadow of COVID-19, we

In 2020, we sponsored two corporate matching programs.
When the pandemic first hit and countries and states went
into lockdown in the early spring of 2020, the Company
announced a $1 million donation to organizations focusing
on food insecurity, children’s assistance and COVID-19
response. In addition, the Company launched a matching
program for employee giving to these organizations,
resulting in combined giving of nearly $2 million.

Later in 2020, we launched a second matching program,
reemphasizing the importance — now more than ever
before — of supporting the communities where we live
and work. Each operating unit was encouraged to select
a charity with a local nexus as well as a humanitarian
component, such as food, education or healthcare. The
charitable match program matched one dollar for each
dollar donated up to a maximum of $10,000 at each
operating unit. With 53 operating units, this meant that if
each operating unit received $10,000 or more in donations
from employees for the charity nominated, W. R. Berkley
Corporation would match $530,000 in charitable dona-
tions. The corporate and match contributions were made
by the W. R. Berkley Corporation Charitable Foundation.

“Being part of a community means more than just
doing business there. Uniting together to help
others brings us closer as colleagues, sets the stage
for our culture and enriches our communities.”

saw a prolonged and consistent effort on the part of our
team members — often at the expense of their own
personal welfare — to help people they often do not know.
At our operating units we have nurses who are volunteer-
ing in high-risk hospitals far from home; we have foster
moms who are delivering food and monitoring the well-
being of at-risk children; we have families who are working
as a team to produce 3D printed parts for personal
respirators and face shields for healthcare workers; and
we have people who are leaving their homes to deliver
food, shop and cook for neighbors, and donate blood.
And there are so many more who are just doing their part
to keep the world running as parents, family members and
neighbors. To all of you, we express our heartfelt thanks.

Total fundraising for Kids’ Chance for
the last 10 years exceeded:

$435,000

Many Berkley operating units support their local business,
art, cultural and scientific communities by developing
meaningful collaborations that strengthen their bonds
with local groups, as well as their connections to clients
and distribution partners. One such collaboration with
the Bruce Museum in Greenwich, Connecticut, offered
opportunities for interesting programming during 2020
as the museum pivoted to hosting events virtually.
The museum revamped its monthly thought leadership
program, creating an online experience with a wider
reach than the traditional in-person series. This year’s
topics covered a wide range, including climate change,
the artists of Instagram, sustainable farming and
“National Geographic” style photography. In addition to
co-sponsoring these and other events, Berkley draws
attention to the museum, its exhibits and programming
by inviting clients and distribution partners to participate,
as well as promoting them on social media. Together,
we continued to promote young area artists despite the
difficulties presented by the pandemic, through the
iCreate talent show, which showcases the talents of high
school students across the tristate area.

•

iCreate selected 55 artworks from over 850
submissions across 123 high schools throughout
Connecticut, New Jersey and New York, for
its annual art exhibition at the Bruce Museum.

Our Company

62541Narrative

29

W. R. Berkley Corporation, founded in 1967,
is one of the nation’s premier commercial
lines property casualty insurance providers.
Each of the operating units within Berkley
participates in a niche market requiring
specialized knowledge about a territory
or product.

Our competitive advantage lies in our long-
term strategy of decentralized operations,
allowing each of our units to identify and
respond quickly and effectively to changing
market conditions and local customer
needs. This decentralized structure provides
financial accountability and incentives to
local management and enables us to attract
and retain the highest-caliber professionals.
We have the expertise and resources to utilize
our strengths in the present environment,
and the flexibility to anticipate, innovate
and respond to whatever opportunities and
challenges the future may hold.

How We Are Different

Risk-Adjusted Returns
Management company-wide is
focused on obtaining the best
potential returns with a real
understanding of the amount of
risk being assumed. Superior risk-
adjusted returns are generated
over the insurance cycle.

Accountability
The business is operated with an
ownership perspective and a clear
sense of fiduciary responsibility
to shareholders.

People-Oriented Strategy
New businesses are started when
opportunities are identified and,
most importantly, when the right
talent is found to lead a business.
Of the Company’s 53 operating
units, 46 were developed internally
and seven were acquired.

Responsible Financial Practices
Risk exposures are managed
proactively. A strong balance sheet,
including a high-quality investment
portfolio, ensures ample resources
to grow the business profitably
whenever there are opportunities
to do so.

Transparency
Consistent and objective standards
are used to measure performance —
and, the same standards are used
regardless of the environment.

Investments

62541Narrative

32

Over the past few years, we have shortened the duration of our fixed income
portfolio to 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
uncertain interest rate environment.

We manage out portfolio for total return, including capital gains. As invest-
ment 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 potential inflation.

We describe these risks and uncertainties in greater detail in Item 1A, Risk Factors. These risks and uncertainties could
cause our actual results for the year 2021 and beyond to differ materially from those expressed in any forward-looking
statement we make. Any projections of growth in our revenues would not necessarily result in commensurate levels of
earnings. Our future financial performance is dependent upon factors discussed elsewhere in this Form 10-K and our other
SEC filings. Forward-looking statements speak only as of the date on which they are made.

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 - 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 the United Kingdom,

Continental Europe, South America, Canada, Mexico, Scandinavia, Asia and Australia.

Reinsurance & Monoline Excess - reinsurance business on a facultative and treaty basis, primarily in the United States,

the United Kingdom, Continental Europe, Australia, the Asia-Pacific region and South Africa, as well as operations

that solely retain risk on an excess basis.

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

products, services or industry served. Each of our operating units 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 units 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 53 operating units, 46 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 operating segments for each of the past three years were as follows:

Thirty 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: “The Financial Strength Rating opinion addresses the relative ability of an insurer to meet its ongoing insurance
obligations. The ratings are not assigned to specific insurance policies or contracts and do 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-four insurance company subsidiaries rated by Standard & Poor's (“S&P”) have financial strength ratings of

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 - 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 the United Kingdom,
Continental Europe, South America, Canada, Mexico, Scandinavia, Asia and Australia.

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

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

products, services or industry served. Each of our operating units 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 units 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 53 operating units, 46 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 operating segments for each of the past three years were as follows:

Thirty 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: “The Financial Strength Rating opinion addresses the relative ability of an insurer to meet its ongoing insurance
obligations. The ratings are not assigned to specific insurance policies or contracts and do 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-four insurance company subsidiaries rated by Standard & Poor's (“S&P”) have financial strength ratings of

A+ (the seventh 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 sixth highest rating out of twenty-one possible ratings).

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

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

"a Berkley company" or collectively as "Berkley companies." Unless otherwise indicated, all references in this Form 10-K to
“Berkley,” “we,” “us,” “our,” the “Company” or similar terms refer to W. R. Berkley Corporation together with its subsidiaries
and operating units. W. R. Berkley Corporation is a Delaware corporation formed in 1970.

Insurance

Our U.S.-based operating units predominantly underwrite commercial insurance business primarily throughout the

United States, although many units offer coverage globally, focusing on the following general areas:

Excess & Surplus Lines: A number of our operating units 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 operating units
include premises operations, commercial automobile, property, products liability, general liability and professional liability
lines. Products are generally distributed through wholesale agents and brokers.

Industry Specialty: Certain other operating units 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 these unique exposures, 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 operating unit 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 operating units 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 units 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 operating units offer standard insurance products and services focused on meeting the specific needs
of a geographically differentiated customer base. Key clients of these units are small-to-midsized businesses. These regionally
focused operating units 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.

In addition, through our non-U.S. insurance operating units, we write business in more than 60 countries worldwide, with

branches or offices in 29 locations outside the United States, including the United Kingdom, Continental Europe, South
America, Canada, Mexico, Scandinavia, Asia and Australia. In each of our operating territories, we have built decentralized
structures that allow products and services to be tailored to each regional customer base. Our businesses are managed by teams
of professionals with expertise in local markets and knowledge of regional environments.

including claims, administrative and consulting services.

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.

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

compensation reserves that were discounted was $1,655 million and $1,731 million at December 31, 2020 and 2019,
respectively. The aggregate net discount for those reserves, after reflecting the effects of ceded reinsurance, was $483 million
and $530 million at December 31, 2020 and 2019, respectively. At December 31, 2020, discount rates by year ranged from
0.7% to 6.5%, with a weighted average discount rate of 3.6%.

Substantially all discounted workers’ compensation reserves (97% of total discounted reserves at December 31, 2020)

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, 2020), 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.

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

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

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.

written before adoption of the absolute exclusion was $19 million at December 31, 2020 and $24 million at December 31, 2019.
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.

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

The table below provides a reconciliation of the beginning of year and end of year property casualty reserves for the

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.

____________________________________
(1) The cumulative effect adjustment resulting from changes in accounting principals relates to the allowance for expected
credit losses on reinsurance recoverables that commenced on January 1, 2020 due to the adoption of ASU 2016-13. See
Note 1 for more details.

(2) Claims occurring during the current year are net of loss reserve discounts of $10 million, $20 million and $24 million in

2020, 2019 and 2018, respectively.

(3) 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 $21 million in 2020, and increased by $19 million in 2019 and
decreased by $4 million in 2018, respectively.

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

years are offset by additional or return premiums.

Also, see Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and note

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 subject to varying degrees of regulation and supervision in the jurisdictions in which

they do business.

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 excess and surplus and reinsurance

subsidiaries, must generally file all rates with the insurance department of each state in which they operate. Our excess and
surplus and reinsurance subsidiaries generally operate free of rate and form regulation.

Legislative and Regulatory Activity Related to the COVID-19 Pandemic. Since March 2020, U.S. state insurance

regulators have issued directives and guidance in response to the economic impacts of the COVID-19 pandemic, which have
encouraged or directed insurance companies to implement accommodations such as extending grace periods for premium
payments and forbearing on the cancellation or non-renewal of policies due to non-payment of premium. In addition, there has
been industry and regulatory discussion regarding the appropriate role of pandemic business interruption coverage, which could
potentially mandate retroactive coverage of pandemic-related business interruption losses that insurance policies would not
otherwise cover and were not priced to cover such losses. In December 2020, the National Association of Insurance
Commissioners (“NAIC”) expressed its view that a federal mechanism is necessary to address the business interruption
coverage gap for pandemic risk. Proposals for a prospective federal backstop for pandemic business interruption coverages are
currently under development and consideration. These legislative and regulatory initiatives may adversely affect our business.
See “Risk Factors — Risks Related to Our Industry — The COVID-19 pandemic has materially and adversely affected our
results of operations, and is expected to continue and therefore may materially and adversely affect, our results of operations,
financial position and liquidity.”

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 state insurance commissioner, including information concerning our capital structure, ownership, financial
condition and general business operations.

In addition, we must annually submit to our lead state regulator 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.

Nearly all states have also 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, as discussed below under “- International Regulation.” This framework includes a
risk-based, group-wide global insurance capital standard (“ICS”), which will undergo a five-year monitoring period that started
in January 2020. In the U.S., 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. The NAIC adopted the group capital calculation methodology and amendments to the NAIC’s
model holding company act and regulation. These amendments, which implement the annual filing requirement for the group
capital calculation, now have to be adopted by state legislatures in order to become effective.

Nearly 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”). The ORSA 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 ORSA, we are required to:

regularly, no less than annually, conduct an ORSA 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 a confidential high-level ORSA Summary Report annually to the Commissioner of Insurance of the State of

Delaware (our lead state commissioner).

Cybersecurity Regulations. New York’s cybersecurity regulation for financial services institutions that are authorized by

the New York State Department of Financial Services ("Part 500"), including our insurance subsidiaries licensed in New York,
became effective on March 1, 2017. The regulation requires these entities to  assess risks associated with their information
systems and establish and maintain a cybersecurity program designed to protect consumers’ private data and the confidentiality,
integrity and availability of the licensee’s information systems. On October 24, 2017, the NAIC adopted the Insurance Data
Security Model Law (the “Cybersecurity Model Law”), which establishes standards for data security, the investigation of
cybersecurity events involving unauthorized access to, or the 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. Its implementation will be based on adoption by state

legislatures. As of December 31, 2020, the Cybersecurity Model Law had been adopted by 11 states, including one of our
domiciliary states. Importantly, a drafting note in the Cybersecurity Model Law states that a licensee’s compliance with the
New York cybersecurity regulation is intended to constitute compliance with the Cybersecurity Model Law.

Certain states are developing or have developed regulations related to privacy and data security. For example, in 2018

California enacted the California Consumer Privacy Act (“CCPA”), which 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. 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
consumers. CCPA became effective on January 1, 2020, and compliance with the CCPA may increase the cost of providing our
services in California. Other states have considered - and may adopt - similar proposals. We cannot predict the impact, if any,
that any proposed or future cybersecurity regulations will have on our business, financial condition or results of operations.

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 any RBC action level as of December 31, 2020.

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 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, which
many states have adopted, limits assessments to an insurer to 2% of its subject premium and permits recoupment of assessments
through rate setting. Likewise, several states (or underwriting 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
arrangement 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 commercial 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 based on 20% of earned premium for the prior year for covered lines of
commercial property and casualty insurance. Based on our 2020 earned premiums, our aggregate deductible under TRIPRA
during 2021 will be approximately $1,014 million. The federal program will not pay losses for certified acts unless such losses
exceed $200 million industry-wide for any calendar year after 2020. 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
the 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.  In September 2020, the New York State Department of Financial Services (the

“NYDFS”) issued a circular letter to New York domestic and foreign insurance companies, which impacts our insurance
subsidiaries licensed in New York. The circular letter states that the NYDFS expects insurers to integrate financial risks related
to climate change into their governance frameworks, risk management processes and business strategies. For example, the letter
states that an insurer should designate a board member or board committee, as well as a senior management function, that
oversees the management of the financial risks associated with climate change. The NYDFS will publish guidance on climate-
related financial supervision, and it will incorporate questions on this topic into their examinations starting in 2021.

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

business of insurance, federal initiatives could have an impact on our business in a variety of ways. The Dodd-Frank Wall
Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”) effected sweeping changes to financial services
regulation in the United States. The Dodd-Frank Act created two new federal government bodies, the Federal Insurance Office
(the “FIO”) and the Financial Stability Oversight Council (the “FSOC”), which may impact the regulation of insurance.
Although the FIO has preemption authority over state insurance laws that conflict with certain international agreements, it does
not have general supervisory or regulatory authority over the business of insurance. The FIO 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. In May 2018, the Economic Growth, Regulatory Relief and Consumer
Protection Act (“Economic Growth Act”) was signed into law.  Among other things, the Economic Growth Act addresses the
roles played by federal regulators at international insurance standard-setting forums. 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, and in September 2017, the
U.S. and the European Union ("EU") signed such a covered agreement (the "EU Covered Agreement").

The EU Covered Agreement addresses three areas of prudential supervision: reinsurance, group supervision and the

exchange of information between the U.S. and EU. Under the EU Covered Agreement, reinsurance collateral requirements will
no longer apply to qualifying EU reinsurers that sell reinsurance to the U.S. market, and U.S. reinsurers operating in the EU

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

62541 10K

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 commercial 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 based on 20% of earned premium for the prior year for covered lines of
commercial property and casualty insurance. Based on our 2020 earned premiums, our aggregate deductible under TRIPRA
during 2021 will be approximately $1,014 million. The federal program will not pay losses for certified acts unless such losses
exceed $200 million industry-wide for any calendar year after 2020. 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
the 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.  In September 2020, the New York State Department of Financial Services (the

“NYDFS”) issued a circular letter to New York domestic and foreign insurance companies, which impacts our insurance
subsidiaries licensed in New York. The circular letter states that the NYDFS expects insurers to integrate financial risks related
to climate change into their governance frameworks, risk management processes and business strategies. For example, the letter
states that an insurer should designate a board member or board committee, as well as a senior management function, that
oversees the management of the financial risks associated with climate change. The NYDFS will publish guidance on climate-
related financial supervision, and it will incorporate questions on this topic into their examinations starting in 2021.

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

business of insurance, federal initiatives could have an impact on our business in a variety of ways. The Dodd-Frank Wall
Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”) effected sweeping changes to financial services
regulation in the United States. The Dodd-Frank Act created two new federal government bodies, the Federal Insurance Office
(the “FIO”) and the Financial Stability Oversight Council (the “FSOC”), which may impact the regulation of insurance.
Although the FIO has preemption authority over state insurance laws that conflict with certain international agreements, it does
not have general supervisory or regulatory authority over the business of insurance. The FIO 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. In May 2018, the Economic Growth, Regulatory Relief and Consumer
Protection Act (“Economic Growth Act”) was signed into law.  Among other things, the Economic Growth Act addresses the
roles played by federal regulators at international insurance standard-setting forums. 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, and in September 2017, the
U.S. and the European Union ("EU") signed such a covered agreement (the "EU Covered Agreement").

The EU Covered Agreement addresses three areas of prudential supervision: reinsurance, group supervision and the

exchange of information between the U.S. and EU. Under the EU Covered Agreement, reinsurance collateral requirements will
no longer apply to qualifying EU reinsurers that sell reinsurance to the U.S. market, and U.S. reinsurers operating in the EU

market will no longer be subject to “local presence” requirements. The EU Covered Agreement establishes group supervision
practices that apply only to U.S. and EU insurance groups operating in both territories. For instance, the EU Covered
Agreement states that, provided the U.S. has adopted group supervision including worldwide group governance, solvency,
capital and reporting, U.S.-headquartered insurance groups with operations in the EU will be supervised at the worldwide level
only by U.S. insurance regulators precluding EU insurance supervisors from exercising solvency and capital requirements over
the worldwide operations of U.S.-headquartered insurers. Under the Dodd-Frank Act, the FIO has preemption authority over
state insurance laws that conflict with the EU Covered Agreement.

In late 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”), which will extend the benefits of a covered
agreement to the U.K. after Brexit. The agreement between the U.S. and the U.K. largely reflects the provisions of the EU
Covered Agreement and incorporates the same timeframes within it.

Under the terms of such EU and U.K. Covered Agreements, beginning September 1, 2022, 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 may
be preempted by the applicable Covered Agreement. Accordingly, in June 2019, the NAIC adopted amendments to its Credit
for Reinsurance Model Law in order to satisfy the substantive and timing requirements of the Covered Agreements and to pave
the way for U.S. states to similarly amend their credit for reinsurance laws and avoid potential federal pre-emption of these
laws. These amendments will become an NAIC accreditation standard beginning September 1, 2022, with enforcement
beginning on January 1, 2023. The newly amended Credit for Reinsurance Model Law also extends the zero reinsurance
collateral provisions in the Covered Agreements to 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 the NAIC has identified as “reciprocal
jurisdictions” pursuant to the NAIC Qualified Jurisdiction Process. 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 FIO also can recommend to the FSOC that it 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, i.e., a “systemically important financial
institution” or a “non-bank SIFI.” An insurer so designated by the FSOC will be subject to Federal Reserve supervision and
heightened prudential standards. There are currently no such non-bank SIFIs designated by the FSOC. On December 4, 2019,
the FSOC approved final guidance related to a revised process for designating non-bank SIFIs, which substantially changed its
previous procedures by adopting an activities-based approach and moving away from the entities-based approach. The final
guidance became effective on January 29, 2020.

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 systemically important non-bank financial companies.

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, while 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, 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.

Following the expiry of the transition period for the United Kingdom’s withdrawal from the EU on December 31,

2020, an insurance company with authorization to write insurance business in the U.K. is no longer permitted to provide cross-
border services on a “passporting” basis in the remaining member states of the European Economic Area (“EEA”), a group
including member states of the EU and Norway, Liechtenstein and Iceland. Instead, U.K. insurance companies are now required
to establish either a subsidiary or a branch in an EEA member state and apply for direct authorization with the local regulator in
that jurisdiction.

EEA insurers have similarly lost their right to provide cross-border services on a “passporting” basis into the U.K. As

a result, the U.K. branch of our Liechtenstein subsidiary has applied for direct authorization to carry on insurance business in
the U.K. In the meantime, the branch is currently able to perform regulated insurance business in the U.K. under the supervision
of the PRA/FCA pursuant to the U.K. ‘Temporary Permissions Regime’ while the application is being considered.

See below “Risks Relating To Our Business-The United Kingdom leaving the EU could adversely affect our business”

for more information.

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 which became effective on January 1, 2016. Following
the U.K.’s withdrawal from the EU, and the expiry of the transition period on December 31, 2020, our Lloyd’s managing
agency (and the U.K. branch of our Liechtenstein subsidiary) are now subject to a separate U.K. prudential regime. This
domestic regime is identical to Solvency II from January 1, 2021. However, the two regimes may diverge over time. The U.K.
is currently undertaking a review of Solvency II and of the regulatory regime applicable to U.K. authorized insurers and
reinsurers. Lloyd’s applies a capital adequacy test to all Lloyd’s syndicates, including our syndicate, that is based on the U.K.
prudential regime.

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,
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 U.S. system of insurance regulation relating to group

The Liechtenstein financial services regulator, the Financial Markets Authority, is the group supervisor for our

European-regulated subsidiaries. However, both the EU and the U.K. 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 (“GDPR”), which took effect in May 2018. The

regulation’s goal is to impose increased individual rights and protections for all personal data located in or originating from the
EU. The U.K. has also implemented the GDPR. 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 process EU and/or U.K.
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 be 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 internationally active insurance groups (“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. 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 GCC.

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
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 operating units can gain a competitive advantage by responding quickly to changing market conditions. Our
operating units 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 operating units compete with excess and surplus insurers as well as
standard carriers. Other regional units compete with mutual and other regional stock companies as well as national carriers.
Additionally, direct writers of property casualty insurance compete with our regional units 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, Transatlantic Reinsurance, 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, 2021, we employed 7,495 individuals. Of this number, our subsidiaries employed 7,356 persons and

the remaining persons 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 value

driver of our superior 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, operating unit 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.

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 is what unifies our employees across our decentralized business model, 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. The key drivers of

our culture encompass the premises 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 operating units has a unique culture that embodies a shared set of values that define
our enterprise. Our structure, with more than 50 distinct operating units, facilitates the prompt identification of and appropriate
action with respect to addressing individual business or cultural issues arising within an operating unit, without significantly
affecting the larger enterprise. Furthermore, these operating units are overseen by senior corporate business managers and
senior corporate functional managers, including actuarial, claims, underwriting, compliance and finance, providing a unique
governance structure that makes it easier to identify such issues. Additionally, our Board of Directors through, among other
activities, its regular interactions with corporate senior management, 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 the acquisition and startup of complementary businesses and continue to evaluate possible

acquisitions and new ventures on an ongoing basis. In addition, our operating units 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 operating units. 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.

companies in the United States and the NAIC’s development of the GCC.

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

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 operating units can gain a competitive advantage by responding quickly to changing market conditions. Our

operating units 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 operating units compete with excess and surplus insurers as well as

standard carriers. Other regional units compete with mutual and other regional stock companies as well as national carriers.

Additionally, direct writers of property casualty insurance compete with our regional units 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, Transatlantic Reinsurance, 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

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

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

industry.

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. In recent years, we have faced significant competition
in our business, as a result of new entrants and capital providers, as well as existing insurers seeking to gain or maintain market
share. Recently, premium rates have increased at an accelerating pace for most lines of business, while they have decreased in
others, most notably workers' compensation. 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 or social inflation on the amount of compensation due for
injuries or losses. In addition, investment rates of return have impacted rate adequacy, with interest rates remaining at or near
historic lows. 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 have pressured 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 (including ease of doing business over the internet), speed of claims payment and reputation and experience
in the lines to be written. In recent years, the insurance industry has undergone consolidation, which may further increase
competition in some parts of our 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, Transatlantic
Reinsurance, and Partner Re. We expect that perceived financial strength, in particular, will become more important as
customers seek high quality reinsurers.

Over the past several years, increased supply has led to significant competition in our business. Our E&S operating units
have also encountered competition from admitted companies seeking to increase market share. More recently, insurance prices
have generally increased for most lines of business, excluding workers' compensation. However, loss costs have also increased
and the duration and magnitude of the improving pricing environment remains uncertain. With the low level of interest rates
available, 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 some parts of 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 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. 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.

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
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 predict 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.

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 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;

handling and other practices;

increases;

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

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

• 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 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 were $340 million in 2020 (including COVID-19 related losses), $90
million in 2019, and $105 million in 2018. Similarly, man-made catastrophes can also have a material impact on our financial
results.

or obtain appropriate new reinsurance covers with respect to certain exposures under our policies, including COVID-19-related
exposures, 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.

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

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

explosions, severe winter weather and fires, pandemics, as well as terrorist and other man-made activities, including drilling,
mining and other industrial accidents, cyber events or terrorist activities. The incidence and severity of catastrophes are
inherently unpredictable. 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 has materially and adversely affected our results of operations, and is expected to
continue and therefore may materially and adversely affect, our results of operations, financial position and liquidity.

The ongoing COVID-19 pandemic, including the related impact on the U.S. and global economies, has materially and
adversely affected our results of operations. We expect the pandemic and its impact on our business to continue, and potentially
even worsen, but we cannot predict the magnitude or duration of its continued impact, particularly given the great uncertainties
associated with COVID-19, including regarding the reopening of the U.S. and global economies and the recovery from its
devastating economic and other effects. The ultimate impact of COVID-19 on our results of operations, financial position and
liquidity is not yet known, and likely will not be known for some time, but includes the following:

Adverse Legislative and Regulatory Action. Legislative and regulatory initiatives taken or which may be taken in

response to COVID-19 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, 2020, we recorded approximately
$171 million for COVID-19-related losses, net of applicable reinsurance, and reinstatement premiums of approximately $18
million. Of the $171 million of COVID-19-related losses, $95 million are reported losses and $76 million is booked as IBNR.
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. Given the
great uncertainties associated with COVID-19 and its impact and the limited information upon which our current assumptions
and assessments have been made, 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 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.

economic conditions. Consequently, reduced economic activity relating to the COVID-19 pandemic 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). This may continue for an indefinite period, with the magnitude of the
impact impossible to predict. In addition, as we continue to evaluate the effects of COVID-19 on the insurance coverages we
currently offer, our appetite for providing certain coverages in various jurisdictions may change which could further negatively
impact our premium volumes. Any such reduction in our premiums would likely cause our expense ratio to rise.

Investments. Further disruptions in global financial markets due to the continuing impact of COVID-19 could cause us

to incur additional unrealized and/or realized investment losses (beyond the investment fund losses incurred to date), including
impairments in our fixed maturity portfolio and other investments. In addition, the economic uncertainty resulting from
COVID-19 may result in a further decline in interest rates, which may negatively impact our net investment income from future
investment activity.

Credit Risk. As credit risk is generally a function of the economy, we face greater credit risk from our policyholders,

independent agents and brokers in connection with the payment and remittance of premiums as a result of the economic
conditions caused by COVID-19. Similarly, our credit risk related to the reimbursement of deductibles from policyholders and
in connection with reinsurance recoverables has increased.

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 risks and uncertainties
related to the COVID-19 pandemic, 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. In response to the COVID-19
pandemic, we have implemented remote working policies which have resulted 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.

Over the past several 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 growing scientific consensus that global warming and other climate change are altering the
frequency, severity and/or 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 2020 earned premiums, our aggregate deductible under TRIPRA during 2021 is approximately $1,014 million. In
addition, the coverage provided under TRIPRA does not apply to reinsurance that we write.

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

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 COVID-19-related losses 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. In addition, we may be unable to renew our current reinsurance coverages

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;

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 by regulatory authorities, may further restrict the conduct of our business.

Risks Relating to Our Business

Our international operations expose us to investment, political and economic risks, including foreign currency and

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 Financial Stability Oversight Council (“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 Federal Insurance Office (“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 to the FSOC that it 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.

Although state regulation is the primary form of regulation of insurance and reinsurance in the United States, in addition

to the changes brought about by the Dodd-Frank Act, Congress has considered various proposals relating to the creation of an
optional federal charter and repeal of the insurance company antitrust exemption from the McCarran-Ferguson Act. We may be
subject to potentially increased federal oversight as a financial institution. In addition, the change in the U.S. administration and
the volatile political environment may increase 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. Implementation of Solvency II in EU
member states occurred on January 1, 2016, and as the Solvency II regime evolves over time, we may be required to utilize a
significant amount of resources to ensure compliance. In particular, the European Commission and European regulators are
undertaking a review of Solvency II, which is anticipated to be completed in the third quarter of 2021. 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 EU 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.

Similarly, following the U.K.’s withdrawal from the EU, and the expiry of the transition period on December 31, 2020,

our U.K. subsidiaries are now subject to a separate U.K. prudential regime, to which the same considerations will apply. The
U.K.’s domestic prudential regime is currently identical to Solvency II, although the two regimes, and their respective
requirements, may diverge over time. The U.K. has already declared that it considers the Solvency II regime as “equivalent” to
its own. However, the EU is still determining whether to make “equivalency” declarations in respect of the U.K.’s prudential
regime. It is also possible that any “equivalency” determinations made by either side could be withdrawn in the future, which
would adversely affect our capital and compliance requirements.

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

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 and economic
risks, including foreign currency and credit risk. Changes in the value of the U.S. dollar relative to other currencies could 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.

The United Kingdom leaving the EU could adversely affect our business.

In accordance with the withdrawal agreement implementing the U.K. leaving the EU (“Brexit”), the U.K. formally left

the EU on January 31, 2020. The agreement provided for a transitional period, which ended on December 31, 2020, during
which time the U.K. continued to enjoy the same rights and obligations as it had as a member state, though without
participating in the EU institutions. During the transitional period, the U.K. and the EU negotiated a long-term agreement
covering, among other things, the terms of trade between them, culminating in the execution of the entry into a “Trade and
Cooperation Agreement”.

However, notwithstanding the finalization of the Trade and Cooperation Agreement between the U.K. and the EU,

uncertainty remains regarding the impact of Brexit, including the implementation and enforcement of terms and conditions of
the agreement, and the U.K.’s future relationship with the EU. Brexit could also lead to legal uncertainty and differing laws and
regulations between the U.K. and the EU. Specifically in relation to financial services, under the terms of the Trade and
Cooperation Agreement, both EU and U.K. insurers lost their respective passporting rights from January 1, 2021, and it is
unclear whether the EU will make “equivalence” determinations in respect of relevant aspects of U.K. financial services
regulation. As a result, the U.K. branch of our Liechtenstein subsidiary has applied to be directly authorized to perform
insurance business in the U.K., which application remains under consideration.

More generally, barriers to trade resulting from Brexit could affect the attractiveness of the U.K. and impact our U.K.

business. We also face risks associated with the potential uncertainty and consequences related to Brexit, including with respect
to volatility in financial markets, exchange rates and interest rates. These uncertainties could increase the volatility of, or
reduce, our investment results in particular periods or over time. Brexit could adversely affect European or worldwide political,
regulatory, economic or market conditions and could contribute to instability in political institutions and regulatory agencies.

Any of these potential effects, and others we cannot anticipate, could adversely affect our results of operations or

financial condition.

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 operating units, 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

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 by regulatory authorities, may further restrict the conduct of our business.

Risks Relating to Our Business

Our international operations expose us to investment, political and economic risks, including foreign currency and

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 Financial Stability Oversight Council (“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 Federal Insurance Office (“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 to the FSOC that it 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.

Although state regulation is the primary form of regulation of insurance and reinsurance in the United States, in addition

to the changes brought about by the Dodd-Frank Act, Congress has considered various proposals relating to the creation of an

optional federal charter and repeal of the insurance company antitrust exemption from the McCarran-Ferguson Act. We may be

subject to potentially increased federal oversight as a financial institution. In addition, the change in the U.S. administration and

the volatile political environment may increase 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. Implementation of Solvency II in EU

member states occurred on January 1, 2016, and as the Solvency II regime evolves over time, we may be required to utilize a

significant amount of resources to ensure compliance. In particular, the European Commission and European regulators are

undertaking a review of Solvency II, which is anticipated to be completed in the third quarter of 2021. 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 EU 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.

Similarly, following the U.K.’s withdrawal from the EU, and the expiry of the transition period on December 31, 2020,

our U.K. subsidiaries are now subject to a separate U.K. prudential regime, to which the same considerations will apply. The

U.K.’s domestic prudential regime is currently identical to Solvency II, although the two regimes, and their respective

requirements, may diverge over time. The U.K. has already declared that it considers the Solvency II regime as “equivalent” to

its own. However, the EU is still determining whether to make “equivalency” declarations in respect of the U.K.’s prudential

regime. It is also possible that any “equivalency” determinations made by either side could be withdrawn in the future, which

would adversely affect our capital and compliance requirements.

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

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 and economic
risks, including foreign currency and credit risk. Changes in the value of the U.S. dollar relative to other currencies could 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.

The United Kingdom leaving the EU could adversely affect our business.

In accordance with the withdrawal agreement implementing the U.K. leaving the EU (“Brexit”), the U.K. formally left

the EU on January 31, 2020. The agreement provided for a transitional period, which ended on December 31, 2020, during
which time the U.K. continued to enjoy the same rights and obligations as it had as a member state, though without
participating in the EU institutions. During the transitional period, the U.K. and the EU negotiated a long-term agreement
covering, among other things, the terms of trade between them, culminating in the execution of the entry into a “Trade and
Cooperation Agreement”.

However, notwithstanding the finalization of the Trade and Cooperation Agreement between the U.K. and the EU,

uncertainty remains regarding the impact of Brexit, including the implementation and enforcement of terms and conditions of
the agreement, and the U.K.’s future relationship with the EU. Brexit could also lead to legal uncertainty and differing laws and
regulations between the U.K. and the EU. Specifically in relation to financial services, under the terms of the Trade and
Cooperation Agreement, both EU and U.K. insurers lost their respective passporting rights from January 1, 2021, and it is
unclear whether the EU will make “equivalence” determinations in respect of relevant aspects of U.K. financial services
regulation. As a result, the U.K. branch of our Liechtenstein subsidiary has applied to be directly authorized to perform
insurance business in the U.K., which application remains under consideration.

More generally, barriers to trade resulting from Brexit could affect the attractiveness of the U.K. and impact our U.K.
business. We also face risks associated with the potential uncertainty and consequences related to Brexit, including with respect
to volatility in financial markets, exchange rates and interest rates. These uncertainties could increase the volatility of, or
reduce, our investment results in particular periods or over time. Brexit could adversely affect European or worldwide political,
regulatory, economic or market conditions and could contribute to instability in political institutions and regulatory agencies.

Any of these potential effects, and others we cannot anticipate, could adversely affect our results of operations or

financial condition.

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 operating units, 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. 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, 2020, the amount due from our reinsurers was approximately
$2,425 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.

possible acquisitions and new ventures. We cannot assure you that we will be able to identify suitable acquisition targets or
insurance ventures, that such transactions will be financed and completed on acceptable terms or that our future acquisitions or
start-up ventures will be successful. The process of integrating any companies we do acquire or investing in new ventures may
have a material adverse effect on our results of operations and financial condition.

If we experience difficulties with our information technology, telecommunications or other computer systems, our

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

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.

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, or the infection of our systems by a malicious computer virus, 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 our networks and confidential data may expose us to liability.

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

Our operations rely on the secure processing, storage and transmission of confidential and other information in 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.

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

computer systems and networks. Computer viruses, hackers, employee misconduct and other external hazards could expose our
data systems to security breaches. 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 attempt to develop secure data transmission
capabilities with these third-party vendors and others with whom we do business, 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 our proprietary information, whether owing to breaches of our own systems or those
of our vendors, could result in significant monetary and reputational damages, costly litigation, or other regulatory enforcement
actions. These increased risks, and expanding regulatory requirements regarding data security, 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.

or reduce the level of our underwriting commitments.

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

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 possible acquisitions and the creation of new ventures, 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 acquisition candidates or new insurance ventures and even if we do, we may not

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

As part of our present strategy, we continue to evaluate possible acquisition transactions and the start-up of
complementary businesses on an ongoing basis, and at any given time we may be engaged in discussions with respect to

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, 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) or damage to our reputation.

We could be adversely affected by recent and future 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
modifies 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.

Our investment portfolio consists substantially of fixed maturity securities. As of December 31, 2020, our investment in

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

fixed maturity securities was approximately $14.2 billion, or 67.9% 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 (4.3%); state and municipal securities (26.0%); corporate securities (32.9%); asset-backed
securities (22.6%); mortgage-backed securities (7.3%) and foreign government (6.9%).

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 significant inflation or
an increase in interest rates were to occur, the fair value of our fixed maturity securities would be negatively impacted.
Conversely, if interest rates decline, 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. Additionally, given the low interest rate environment, 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 and net realized investment gains or result in investment
losses. Investment returns are currently, and will likely continue to remain, under pressure due to the continued low inflation,
actions by the Federal Reserve, 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 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
will depend on the surplus and future earnings of these subsidiaries. During 2021, the maximum amount of dividends that can
be paid without regulatory approval is approximately $721 million. 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 authorities 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.

Merger and arbitrage trading securities were $341.5 million, or 1.6% of our investment portfolio, including cash and cash

equivalents at December 31, 2020. 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 $2.3 billion, or
11.1% of our investment portfolio, including cash and cash equivalents, at December 31, 2020. 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.

Our investment portfolio consists substantially of fixed maturity securities. As of December 31, 2020, our investment in

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

fixed maturity securities was approximately $14.2 billion, or 67.9% 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 (4.3%); state and municipal securities (26.0%); corporate securities (32.9%); asset-backed

securities (22.6%); mortgage-backed securities (7.3%) and foreign government (6.9%).

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 significant inflation or

an increase in interest rates were to occur, the fair value of our fixed maturity securities would be negatively impacted.

Conversely, if interest rates decline, 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. Additionally, given the low interest rate environment, 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 and net realized investment gains or result in investment

losses. Investment returns are currently, and will likely continue to remain, under pressure due to the continued low inflation,

actions by the Federal Reserve, 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

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 business 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 and enterprise risk management, and actuarial, financial and corporate legal staff 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 operating units to capitalize on various business opportunities. Over

the years, the Company has formed numerous new operating units 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. Returns available on fixed maturity investments
have been at low levels for an extended period.

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.

Effective January 1, 2020, the Company adopted new accounting standard ASU 2016-13 Financial Instruments -

Credit Losses. Refer to Note 1 in the financial statements for further information on the accounting guidance and impact of its
adoption on the Company's results and financial position.

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

adversely affected our results of operations. For the year ended December 31, 2020, the Company recorded approximately $171
million for COVID-19-related losses, net of reinsurance, and reinstatement premiums of approximately $18 million. The
ultimate impact of COVID-19 on the economy and on the Company’s results of operations, financial position and liquidity is
uncertain and not within the Company’s control. The scope, duration and magnitude of the direct and indirect effects of
COVID-19 continue to evolve in ways that are difficult or impossible to anticipate. Despite the effects of COVID-19 to date,
the Company’s financial position and liquidity improved commencing in the second quarter.

The impact of the COVID-19 pandemic on our results of operations, financial position and liquidity is expected to

include, among others:

Adverse Legislative and Regulatory Action. Legislative and regulatory initiatives taken or that may be taken in

response to COVID-19, such as those that seek to retroactively mandate or provide a presumption of coverage for losses which
our insurance policies would not otherwise cover and were not priced to cover, may adversely affect us, particularly in our
workers’ compensation and property coverages businesses.

Claim Losses Related to COVID-19 May Exceed Reserves. Given the great uncertainties associated with COVID-19

and its impact and the limited information upon which our current assumptions and assessments have been made, our reserves
and underlying estimated level of claim losses and costs arising from COVID-19 may materially change.

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 business 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 and enterprise risk management, and actuarial, financial and corporate legal staff 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 operating units to capitalize on various business opportunities. Over

the years, the Company has formed numerous new operating units 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. Returns available on fixed maturity investments
have been at low levels for an extended period.

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.

Effective January 1, 2020, the Company adopted new accounting standard ASU 2016-13 Financial Instruments -

Credit Losses. Refer to Note 1 in the financial statements for further information on the accounting guidance and impact of its
adoption on the Company's results and financial position.

The ongoing COVID-19 pandemic, including the related impact on the U.S. and global economies, has materially and
adversely affected our results of operations. For the year ended December 31, 2020, the Company recorded approximately $171
million for COVID-19-related losses, net of reinsurance, and reinstatement premiums of approximately $18 million. The
ultimate impact of COVID-19 on the economy and on the Company’s results of operations, financial position and liquidity is
uncertain and not within the Company’s control. The scope, duration and magnitude of the direct and indirect effects of
COVID-19 continue to evolve in ways that are difficult or impossible to anticipate. Despite the effects of COVID-19 to date,
the Company’s financial position and liquidity improved commencing in the second quarter.

The impact of the COVID-19 pandemic on our results of operations, financial position and liquidity is expected to

include, among others:

Adverse Legislative and Regulatory Action. Legislative and regulatory initiatives taken or that may be taken in
response to COVID-19, such as those that seek to retroactively mandate or provide a presumption of coverage for losses which
our insurance policies would not otherwise cover and were not priced to cover, may adversely affect us, particularly in our
workers’ compensation and property coverages businesses.

Claim Losses Related to COVID-19 May Exceed Reserves. Given the great uncertainties associated with COVID-19
and its impact and the limited information upon which our current assumptions and assessments have been made, our reserves
and 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 on industry practices and

economic, legal, judicial, social and other environmental conditions continue to evolve, unexpected and unintended issues
related to claims and coverages may emerge (including in the area of property coverages where physical damage requirements
and communicable disease exclusions are currently being challenged).

Reinsurance. Reinsurers may dispute the applicability of reinsurance to COVID-19 related 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. In addition, we may be unable to renew our current reinsurance coverages
or purchase new coverages with respect to certain exposures under our policies, including COVID-19-related exposures.

Premium Volumes May Be Negatively Impacted. Reduced economic activity relating to the COVID-19 pandemic will
likely decrease demand for our insurance products and services. In addition, we may alter our view on the insurance coverages
that are appropriate to offer in various jurisdictions, which could further negatively impact our premium volumes.

Investments. Further disruptions in global financial markets due to the continuing impact of COVID-19 could cause us

to incur additional unrealized and/or realized investment losses, including impairments in our fixed income portfolio and other
investments.

Credit Risk. As credit risk is generally a function of the economy, we face greater credit risk from our policyholders,

independent agents and brokers in connection with the payment and remittance of premiums as a result of the economic
conditions caused by COVID-19. Similarly, our credit risk related to the reimbursement of deductibles from policyholders and
in connection with reinsurance recoverables has increased.

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 response to the COVID-19 pandemic,
we have implemented remote working policies which have resulted 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.

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 operating unit. 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 operating unit.

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.

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 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 operating unit. 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 commercial automobile, 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 2020:

Our net reserves for losses and loss expenses of approximately $11.6 billion as of December 31, 2020 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 $2.6 billion, or 22%, of the Company’s net loss reserves as of December 31, 2020 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

Management considers the impact of delayed reporting and the extended tail in its selection of loss development factors for
these lines of business.

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 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 operating unit. 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 commercial automobile, 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 2020:

Our net reserves for losses and loss expenses of approximately $11.6 billion as of December 31, 2020 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 $2.6 billion, or 22%, of the Company’s net loss reserves as of December 31, 2020 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

The ongoing COVID-19 global pandemic has impacted, and will likely continue to impact, the Company’s results

through its effect on claim frequency and severity. Loss cost trends have been impacted and will likely be further impacted by
COVID-19-related claims in certain lines of business, as well as by other effects of COVID-19 associated with economic
conditions, inflation, and social distancing and work from home rules, for example. Although it is still too early to determine
the net impact, it appears that the losses incurred due to COVID-19-related claims are being offset, to a certain extent, by lower
claim frequency in certain lines of our businesses, including commercial auto, workers’ compensation, and other liability.
However, given the continuing nature of the pandemic, the impact of COVID-19 could ultimately increase or decrease overall
loss cost trends and is likely to have differing impacts on the Company's different lines of business.

Most of the COVID-19-related claims reported to the Company to date involve certain short-tailed lines of business,

including contingency and event cancellation, business interruption, and film production delay. The Company expects
additional claims to be reported for these lines of business. The Company has also received COVID-19-related claims for
longer-tailed casualty lines of business such as workers’ compensation and other liability; however, the estimated incurred loss
impact for these reported claims appears to be modest at this time. Given the continuing uncertainty regarding the pandemic's
pervasiveness, the future impact that the pandemic may have on claim frequency and severity remains uncertain at this time. In
workers’ compensation, for example, nearly two-thirds of the states have enacted rules, legislation or administrative orders
creating a presumption that certain “essential” workers who contract COVID-19 did so through the course of their employment.
Several other states are considering similar actions, including varying the definition of “essential” workers. While the ultimate
impact of these presumptions are unknown at this time, the Company believes that such state actions will likely increase
workers’ compensation claims with respect to workers deemed “essential,” although this impact may be partially offset by
lower workers’ compensation claim frequency with respect to non-essential workers.

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; however, due to COVID-19’s evolving impact
and the still limited amount of available data, there remains a high degree of uncertainty around the Company’s COVID-19
reserves. In addition, several states (and international jurisdictions), through regulation, legislation and/or judicial action,
continue to seek to expand policy coverage terms beyond the policy’s intended coverage, including, for example, but not
limited to, property coverages, where there are attempts to extend business interruption coverage where there is no physical
damage or loss to property, and attempts to disregard policy exclusions for communicable disease. Accordingly, losses arising
from these actions, and the other factors described above, could exceed the Company’s reserves established for those related
policies.

For the year ended December 31, 2020, the Company recognized losses for COVID-19-related claims activity, net of

reinsurance, of approximately $171 million, of which $161 million related to the Insurance segment and $10 million related to
the Reinsurance & Monoline Excess segment. Such $171 million of COVID-19-related losses included $95 million of reported
losses and $76 million of IBNR.

(3) Reinsurance & Monoline Excess includes property and casualty reinsurance as well as operations that solely retain risk on

Favorable prior year development (net of additional and return premiums) was $16 million in 2020.

an excess basis.

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:

Insurance - Reserves for the Insurance segment developed favorably by $24 million in 2020 (net of additional and return

premiums). Continuing the pattern seen in recent years, the overall favorable development in 2020 resulted from more
significant favorable development on workers’ compensation business, which was partially offset by unfavorable development
on professional liability, including excess professional liability.

For workers’ compensation, the favorable development was spread across almost all prior accident years, including prior

to 2011, but was most significant in accident years 2016 through 2019. The favorable workers’ compensation development
reflects a continuation of the benign loss cost trends experienced during recent years, particularly the favorable claim frequency
trends (i.e., number of reported claims per unit of exposure). The long term trend of declining workers’ compensation frequency
can be attributable to improved workplace safety. Loss severity trends were also aided by our continued investment in claims
handling initiatives such as medical case management services and vendor savings through usage of preferred provider
networks and pharmacy benefit managers.  Reported workers’ compensation losses in 2020 continued to be below our
expectations at most of our operating units, and were below the assumptions underlying our initial loss ratio picks and our
previous reserve estimates for most prior accident years.

For professional liability business, unfavorable development was driven mainly by large losses reported in the directors

and officers (“D&O”), lawyers professional and excess hospital professional liability lines of business. For these lines of

business, we continue to see an increase in the number of large losses reported and a lengthening of the reporting “tail” beyond
historical levels.  We believe a contributing cause is rising social inflation in the form of, for example, higher jury awards on
cases that go to trial, and the corresponding higher demands from plaintiffs and higher values required to reach settlement on
cases that do not go to trial. The unfavorable development for professional liability affected mainly accident years 2016 through
2018.

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

$8 million in 2020. The unfavorable development in the segment was driven by non-proportional assumed liability business
written in both the U.S. and U.K., and was partially offset by favorable development on excess workers’ compensation
business. The unfavorable non-proportional assumed liability development was concentrated in accident years 2014 through
2018, and related primarily to accounts insuring construction projects and professional liability exposures.

Favorable prior year development (net of additional and return premiums) was $19 million in 2019.

Insurance - Reserves for the Insurance segment developed favorably by $21 million in 2019 (net of additional and return

premiums). This overall favorable development resulted from more significant favorable development on workers’
compensation business, which was partially offset by unfavorable development on professional liability and general liability
business.

For workers’ compensation, the favorable development was spread across many accident years, including prior to 2010,

but was most significant in accident years 2014 through 2018, and particularly 2017 and 2018. The favorable workers’
compensation development reflects a continuation during 2019 of the benign loss cost trends experienced during recent years,
particularly the favorable claim frequency trends (i.e., number of reported claims per unit of exposure). The long term trend of
declining workers’ compensation frequency can be attributable to improved workplace safety. Loss severity trends were also
aided by our continued investment in claims handling initiatives such as medical case management services and vendor savings
through usage of preferred provider networks and pharmacy benefit managers. Our initial loss ratio “picks” for this line of
business over the past few accident years have contemplated an increase in loss cost trends and reflect decreasing premium rates
in the marketplace; reported workers’ compensation losses in 2019 continued to be below our expectations at most of our
operating units, and were below the assumptions underlying our initial loss ratio picks and our previous reserve estimates.

For professional liability business, the unfavorable development was driven mainly by an increase in the number of large

losses reported in the lawyers professional liability and directors and officers (“D&O”) liability lines of business. Many of the
lawyers large losses involved claims made against insured law firms relating to work performed on matters stemming from the
2008 financial crisis. These claims affected mainly accident years 2013 through 2016. In addition, for both of these lines of
business, we have seen evidence of social inflation in the form of higher jury awards on cases that go to trial, and corresponding
higher demands from plaintiffs and higher values required to reach settlement on cases that do not go to trial. The unfavorable
development for D&O affected mainly accident years 2014 through 2017.

For general liability business, most of the unfavorable development emanated from our excess and surplus lines (E&S)

businesses, and was driven by an increase in the number of large losses reported. Many of these large losses were from
construction and contracting classes of business, which have also been impacted by social inflation.  The general liability
unfavorable development impacted mainly accident years 2015 through 2018.

Reinsurance & Monoline Excess - Reserves for the Reinsurance & Monoline Excess segment developed unfavorably by
$2 million in 2019. The unfavorable development in the segment was driven by non-proportional assumed liability business in
both the U.S. and U.K., and was largely offset by favorable development on excess workers’ compensation business. The
unfavorable non-proportional assumed liability development was concentrated in accident years 2015 through 2018, and
included an adjustment for the Ogden discount rate in the U.K.

Favorable prior year development (net of additional and return premiums) was $39 million in 2018.

Insurance - Reserves for the Insurance segment developed favorably by $19 million in 2018. The favorable development

was primarily attributable to workers’ compensation business, and was partially offset by unfavorable development for
professional liability business.

For workers’ compensation, the favorable development was spread across many accident years, but was most significant
in accident years 2015 through 2017. The favorable workers’ compensation development reflects a continuation during 2018 of
the benign loss cost trends experienced during recent years, particularly the favorable claim frequency trends (i.e., number of
reported claims per unit of exposure). The long term trend of declining workers' compensation frequency can be attributable to
improved workplace safety.  Loss severity trends were also aided by our continued investment in claims handling initiatives
such as medical case management services and vendor savings through usage of preferred provider networks. Reported

the assumptions underlying our previous reserve estimates.

For professional liability business, adverse development was primarily related to unexpected large directors and officers

(“D&O”) liability losses at one of our U.S. operating units, as well as lawyers professional liability losses at another operating
unit.  The adverse development stemmed primarily from accident years 2015 and 2016, and was driven by a higher frequency
of large losses than we had experienced in previous years.

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

$20 million in 2018. The favorable development was primarily due to excess workers’ compensation business, and was spread
across many accident years, including years prior to 2009. This favorable excess workers’ compensation development was
partially offset by unfavorable development on U.S. casualty facultative assumed business from accident years 2009 and prior
related to construction projects.

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

workers’ compensation reserves that were discounted was $1,655 million and $1,731 million at December 31, 2020 and 2019,
respectively. The aggregate net discount for those reserves, after reflecting the effects of ceded reinsurance, was $483 million
and $530 million at December 31, 2020 and 2019, respectively. At December 31, 2020, discount rates by year ranged from
0.7% to 6.5%, with a weighted average discount rate of 3.6%.

Substantially all discounted workers’ compensation reserves (97% of total discounted reserves at December 31, 2020)

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, 2020), 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 $44 million and $43 million at December 31, 2020 and
2019, 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. Effective January 1,
2020, the allowance is adjusted for any change in expected credit losses and subsequent recoveries through net investment gains
(losses). The impairment related to non-credit factors is recognized in other comprehensive income (loss) .

business, we continue to see an increase in the number of large losses reported and a lengthening of the reporting “tail” beyond

historical levels.  We believe a contributing cause is rising social inflation in the form of, for example, higher jury awards on

cases that go to trial, and the corresponding higher demands from plaintiffs and higher values required to reach settlement on

cases that do not go to trial. The unfavorable development for professional liability affected mainly accident years 2016 through

2018.

business.

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

$8 million in 2020. The unfavorable development in the segment was driven by non-proportional assumed liability business

written in both the U.S. and U.K., and was partially offset by favorable development on excess workers’ compensation

business. The unfavorable non-proportional assumed liability development was concentrated in accident years 2014 through

2018, and related primarily to accounts insuring construction projects and professional liability exposures.

Favorable prior year development (net of additional and return premiums) was $19 million in 2019.

Insurance - Reserves for the Insurance segment developed favorably by $21 million in 2019 (net of additional and return

premiums). This overall favorable development resulted from more significant favorable development on workers’

compensation business, which was partially offset by unfavorable development on professional liability and general liability

For workers’ compensation, the favorable development was spread across many accident years, including prior to 2010,

but was most significant in accident years 2014 through 2018, and particularly 2017 and 2018. The favorable workers’

compensation development reflects a continuation during 2019 of the benign loss cost trends experienced during recent years,

particularly the favorable claim frequency trends (i.e., number of reported claims per unit of exposure). The long term trend of

declining workers’ compensation frequency can be attributable to improved workplace safety. Loss severity trends were also

aided by our continued investment in claims handling initiatives such as medical case management services and vendor savings

through usage of preferred provider networks and pharmacy benefit managers. Our initial loss ratio “picks” for this line of

business over the past few accident years have contemplated an increase in loss cost trends and reflect decreasing premium rates

in the marketplace; reported workers’ compensation losses in 2019 continued to be below our expectations at most of our

operating units, and were below the assumptions underlying our initial loss ratio picks and our previous reserve estimates.

For professional liability business, the unfavorable development was driven mainly by an increase in the number of large

losses reported in the lawyers professional liability and directors and officers (“D&O”) liability lines of business. Many of the

lawyers large losses involved claims made against insured law firms relating to work performed on matters stemming from the

2008 financial crisis. These claims affected mainly accident years 2013 through 2016. In addition, for both of these lines of

business, we have seen evidence of social inflation in the form of higher jury awards on cases that go to trial, and corresponding

higher demands from plaintiffs and higher values required to reach settlement on cases that do not go to trial. The unfavorable

development for D&O affected mainly accident years 2014 through 2017.

For general liability business, most of the unfavorable development emanated from our excess and surplus lines (E&S)

businesses, and was driven by an increase in the number of large losses reported. Many of these large losses were from

construction and contracting classes of business, which have also been impacted by social inflation.  The general liability

unfavorable development impacted mainly accident years 2015 through 2018.

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

$2 million in 2019. The unfavorable development in the segment was driven by non-proportional assumed liability business in

both the U.S. and U.K., and was largely offset by favorable development on excess workers’ compensation business. The

unfavorable non-proportional assumed liability development was concentrated in accident years 2015 through 2018, and

included an adjustment for the Ogden discount rate in the U.K.

Favorable prior year development (net of additional and return premiums) was $39 million in 2018.

Insurance - Reserves for the Insurance segment developed favorably by $19 million in 2018. The favorable development

was primarily attributable to workers’ compensation business, and was partially offset by unfavorable development for

professional liability business.

For workers’ compensation, the favorable development was spread across many accident years, but was most significant

in accident years 2015 through 2017. The favorable workers’ compensation development reflects a continuation during 2018 of

the benign loss cost trends experienced during recent years, particularly the favorable claim frequency trends (i.e., number of

reported claims per unit of exposure). The long term trend of declining workers' compensation frequency can be attributable to

improved workplace safety.  Loss severity trends were also aided by our continued investment in claims handling initiatives

such as medical case management services and vendor savings through usage of preferred provider networks. Reported

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

workers’ compensation reserves that were discounted was $1,655 million and $1,731 million at December 31, 2020 and 2019,
respectively. The aggregate net discount for those reserves, after reflecting the effects of ceded reinsurance, was $483 million
and $530 million at December 31, 2020 and 2019, respectively. At December 31, 2020, discount rates by year ranged from
0.7% to 6.5%, with a weighted average discount rate of 3.6%.

Substantially all discounted workers’ compensation reserves (97% of total discounted reserves at December 31, 2020)

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

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

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. Effective January 1,

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, 2020, the Company has recorded an allowance for expected credit losses on fixed maturity

securities of $3 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 $5 million and $2 million as of December 31, 2020 and December 31, 2019, 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
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.

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, 2020, 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.

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, 2020, the Company has recorded an allowance for expected credit losses on fixed maturity

securities of $3 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 $5 million and $2 million as of December 31, 2020 and December 31, 2019, 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

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.

valuation and to verify our understanding of how securities are priced. As of December 31, 2020, 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.

The Company reported net income of $531 million in 2020 compared to $682 million in 2019. The $151 million
decrease in net income was primarily due to an after-tax decrease in net investment income of $47 million mainly due to
reduced investment yields in fixed maturity securities and repositioning a larger portion of the investment portfolio to cash and
cash equivalents, an after-tax decrease in underwriting income of $46 million resulted from COVID-19-related losses and other
catastrophe losses, a $39 million increase in tax expense due to change in effective tax rate, a $23 million decrease in after-tax
foreign currency gains as the U.S. dollar weakened against a wide spectrum of currencies, a decrease in after-tax net investment
gains of $13 million, a $6 million debt extinguishment expense on debt redeemed in 2020 and an after-tax decrease in other
income of $1 million, partially offset by an after-tax reduction in corporate expenses of $12 million, an after-tax increase in
insurance service fee income of $9 million, an after-tax reduction of $2 million from interest expense, and an after-tax increase
in income from non-insurance businesses of $1 million. The number of weighted average diluted shares decreased by
approximately 5 million for 2020 compared to 2019, mainly reflecting shares repurchased in 2020.

Premiums. Gross premiums written were $8,848 million in 2020, an increase of 7% from $8,262 million in 2019. The

increase was due to the growth in the Insurance segment of $439 million and $147 million in the Reinsurance & Monoline
Excess segment. Approximately 79% of premiums expiring in 2020 were renewed, and 80% of premiums expiring in 2019
were renewed.

Average renewal premium rates for insurance and facultative reinsurance increased 11.3% in 2020 and 4.8% in 2019,

when adjusted for changes in exposures. Average renewal premium rates for insurance and facultative reinsurance excluding
workers' compensation increased 13.6% in 2020 and 6.9% in 2019, when adjusted for changes in exposures.

A summary of gross premiums written in 2020 compared with 2019 by line of business within each business segment

follows:

compensation.

•

Insurance gross premiums increased 6% to $7,837 million in 2020 from $7,398 million in 2019. Gross premiums

increased $270 million (11%) for other liability, $196 million (20%) for professional liability, and $92 million (5%)

for short-tail lines and $74 million (9%) for commercial auto, and decreased $193 million (15%) for workers'

•

Reinsurance & Monoline Excess gross premiums increased 17% to $1,010 million in 2020 from $864 million in

2019. Gross premiums written increased $105 million (22%) for casualty lines, $27 million (14%) for property lines,

and $14 million (7%) for monoline excess.

Net premiums written were $7,262 million in 2020, an increase of 6% from $6,863 million in 2019. Ceded reinsurance

premiums as a percentage of gross written premiums were 18% in 2020 and 17% in 2019.

Premiums earned increased 4% to $6,931 million in 2020 from $6,633 million in 2019. 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 2020 are related to business written during both 2020 and 2019. Audit
premiums were $128 million in 2020 compared with $199 million in 2019.

Net investment income decreased 10% to $584 million in 2020 from $646 million in 2019 primarily due to a $92

million decrease in income from fixed maturity securities driven by lower investment yields and repositioning a larger portion
of the investment portfolio to cash and cash equivalents, a $15 million decrease in income from investment funds and an
increase in investment expenses of $3 million, partially offset by a $43 million increase in arbitrage trading account and a $5
million increase in equity securities. Investment funds are reported on a one quarter lag. The average annualized yield for fixed
maturity securities was 2.7% in 2020 and 3.4% in 2019. The effective duration of the fixed maturity portfolio was 2.4 years at
December 31, 2020 and 2.8 years at December 31, 2019. The Company shortened the 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 $20.0 billion in 2020 and $19.1 billion in 2019.

Insurance Service Fees. The Company earns fees from an insurance distribution business, a third-party administrator,

and as a servicing carrier of workers' compensation assigned risk plans for certain states. Insurance service fees were $89
million in 2020 and $93 million in 2019. The decrease was primarily due to a reduction of assigned risk plan business.

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 $74 million in 2020 compared with $121 million in 2019. In 2020, the gains reflected net realized gains on
investment of $99 million, including the sale of a building for a gain of $105 million, and decreased by a change in unrealized

losses on equity securities of $25 million. In 2019, the gains reflected net realized gains on investment sales of $36 million and
increased by a change in unrealized gains on equity securities of $85 million.

Service expenses, which represent the costs associated with the fee-based businesses, decreased 15% to $86 million in

2020 from $101 million in 2019. The decrease is primarily due to a reduction of assigned risk plan business.

Change in Allowance for Expected Credit Losses on Investments. Effective January 1, 2020, the Company adopted

Net foreign currency losses (gains) result from transactions denominated in a currency other than an operating unit’s

accounting guidance for credit losses on financial instruments. The cumulative effect adjustment from the change in accounting
principle was $25 million after-tax, which decreased opening retained earnings and increased AOCI. 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. For the year ended December 31, 2020, the pre-tax change in allowance for expected credit
losses on investments decreased by $29 million ($23 million after-tax), which is reflected in net investment gains (losses).

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 $390 million in 2020 and $407 million in 2019. The decrease mainly relates to a reduction
in revenues from the aviation-related businesses impacted by COVID-19.

Losses and Loss Expenses. Losses and loss expenses increased to $4,469 million in 2020 from $4,131 million in 2019.
The consolidated loss ratio was 64.5% in 2020 and 62.3% in 2019. Catastrophe losses, net of reinsurance recoveries, were $340
million (including losses of approximately $171 million related to COVID-19) in 2020 compared with $90 million in 2019.
Favorable prior year reserve development (net of premium offsets) was $16 million in 2020 compared with $19 million in 2019.
The loss ratio excluding catastrophe losses and prior year reserve development decreased 1.4 points to 59.8% in 2020 from
61.2% in 2019.

A summary of loss ratios in 2020 compared with 2019 by business segment follows:

•

•

Insurance - The loss ratio of 64.9% in 2020 was 2.5 points higher than the loss ratio of 62.4% in 2019. Catastrophe
losses were $307 million in 2020 compared with $68 million in 2019. The Company reflected a best estimate (net of
reinsurance) based upon available information for COVID-19-related losses of approximately $161 million, which
was included in catastrophe losses and primarily related to contingency and event cancellation coverage, workers’
compensation and short-tail lines. Favorable prior year reserve development was $24 million in 2020 compared with
$21 million in 2019. The loss ratio excluding catastrophe losses and prior year reserve development decreased 1.4
points to 60.2% in 2020 from 61.6% in 2019.

Reinsurance & Monoline Excess - The loss ratio of 61.3% in 2020 was 0.2 points lower than the loss ratio of 61.5%
in 2019. Catastrophe losses were $33 million in 2020 compared with $22 million in 2019. The Company reflected a
best estimate (net of reinsurance) based upon available information for COVID-19-related losses of approximately
$10 million, which was included in catastrophe losses and primarily related to excess workers’ compensation and
short-tail lines. Adverse prior year reserve development was $8 million in 2020 compared with adverse prior year
reserve development of $2 million in 2019. The loss ratio excluding catastrophe losses and prior year reserve
development decreased 1.5 points to 56.6% in 2020 from 58.1% in 2019.

functional currency. Net foreign currency losses were $0.4 million in 2020 compared to gains of $31 million in 2019, mainly
due to U.S. dollar weakening in relation to a wide spectrum of currencies in 2020.

Debt extinguishment costs of $8 million in 2020 related to the redemption of subordinated debentures that were due in

2053.

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 decreased to $185 million in 2020 from $201 million in 2019 primarily due to a reduction in non-recurring
performance-based compensation costs which occurred in 2019 and reduced travel-related expenses due to COVID-19 in 2020.

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 $384 million in 2020 compared to $403 million in
2019. The decrease mainly relates to a reduction of aviation-related business impacted by COVID-19 in 2020.

Interest Expense. Interest expense was $151 million in 2020 compared with $153 million in 2019. During 2019, the

Company repaid at maturity $489 million aggregate principal amount of senior notes and other debt. In December 2019, the
Company issued $300 million aggregate principal amount of 5.10% subordinated debentures due 2059. In May 2020, the
Company issued $300 million aggregate principal amount of 4.00% senior notes due 2050. In September 2020, the Company
issued an additional $170 million aggregate principal amount of 4.00% senior notes due 2050 and issued $250 million
aggregate principal amount of 4.25% subordinated debentures due 2060 and repaid $300 million aggregate principal amount of
5.375% senior notes at maturity. In October 2020, the Company redeemed $350 million aggregate principal amount of 5.625%
subordinated debentures due 2053. Accordingly, the timing of the repayments of debt at maturity and redemption that took
place throughout 2019 and 2020 and issuances in 2019 and 2020 led to the decrease in interest expense for the year ended
December 31, 2020 compared to 2019. The redemption of debentures and issuance of additional debentures in 2021, as
described below in "Liquidity and Capital Resources -- Debt," are also expected to impact interest expense in 2021.

Income Taxes. The effective income tax rate was 24.4% in 2020 and 19.8% in 2019. The effective income tax rate

differs from the federal income tax rate of 21% principally because the utilization of losses in certain foreign jurisdictions was
limited, which was partially offset by tax-exempt investment income and tax benefits related to equity-based compensation. See
Note 16 of the Consolidated Financial Statements for a reconciliation of the income tax expense and the amounts computed by
applying the Federal and foreign income tax rate of 21%.

The Company has not provided U.S. deferred income taxes on the undistributed earnings of approximately $111

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.

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 1% and net premiums earned increased 4% from 2019. The expense ratio (policy acquisition and insurance operating
expenses expressed as a percentage of premiums earned) was 30.4% in 2020 and 31.5% in 2019. The improvement is primarily
attributable to higher net premiums earned and lower travel and entertainment expenses due to the global pandemic. However,
to the extent our net premiums earned decrease, due to the impact of the COVID-19 pandemic or otherwise, our expense ratio
would be expected to increase.

losses on equity securities of $25 million. In 2019, the gains reflected net realized gains on investment sales of $36 million and

Service expenses, which represent the costs associated with the fee-based businesses, decreased 15% to $86 million in

increased by a change in unrealized gains on equity securities of $85 million.

2020 from $101 million in 2019. The decrease is primarily due to a reduction of assigned risk plan business.

Change in Allowance for Expected Credit Losses on Investments. Effective January 1, 2020, the Company adopted

accounting guidance for credit losses on financial instruments. The cumulative effect adjustment from the change in accounting

principle was $25 million after-tax, which decreased opening retained earnings and increased AOCI. 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. For the year ended December 31, 2020, the pre-tax change in allowance for expected credit

losses on investments decreased by $29 million ($23 million after-tax), which is reflected in net investment gains (losses).

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 $390 million in 2020 and $407 million in 2019. The decrease mainly relates to a reduction

in revenues from the aviation-related businesses impacted by COVID-19.

Losses and Loss Expenses. Losses and loss expenses increased to $4,469 million in 2020 from $4,131 million in 2019.
The consolidated loss ratio was 64.5% in 2020 and 62.3% in 2019. Catastrophe losses, net of reinsurance recoveries, were $340

million (including losses of approximately $171 million related to COVID-19) in 2020 compared with $90 million in 2019.

Favorable prior year reserve development (net of premium offsets) was $16 million in 2020 compared with $19 million in 2019.

The loss ratio excluding catastrophe losses and prior year reserve development decreased 1.4 points to 59.8% in 2020 from

61.2% in 2019.

A summary of loss ratios in 2020 compared with 2019 by business segment follows:

•

Insurance - The loss ratio of 64.9% in 2020 was 2.5 points higher than the loss ratio of 62.4% in 2019. Catastrophe

losses were $307 million in 2020 compared with $68 million in 2019. The Company reflected a best estimate (net of

reinsurance) based upon available information for COVID-19-related losses of approximately $161 million, which

was included in catastrophe losses and primarily related to contingency and event cancellation coverage, workers’

compensation and short-tail lines. Favorable prior year reserve development was $24 million in 2020 compared with

$21 million in 2019. The loss ratio excluding catastrophe losses and prior year reserve development decreased 1.4

points to 60.2% in 2020 from 61.6% in 2019.

•

Reinsurance & Monoline Excess - The loss ratio of 61.3% in 2020 was 0.2 points lower than the loss ratio of 61.5%

in 2019. Catastrophe losses were $33 million in 2020 compared with $22 million in 2019. The Company reflected a

best estimate (net of reinsurance) based upon available information for COVID-19-related losses of approximately

$10 million, which was included in catastrophe losses and primarily related to excess workers’ compensation and

short-tail lines. Adverse prior year reserve development was $8 million in 2020 compared with adverse prior year

reserve development of $2 million in 2019. The loss ratio excluding catastrophe losses and prior year reserve

development decreased 1.5 points to 56.6% in 2020 from 58.1% in 2019.

Net foreign currency losses (gains) result from transactions denominated in a currency other than an operating unit’s
functional currency. Net foreign currency losses were $0.4 million in 2020 compared to gains of $31 million in 2019, mainly
due to U.S. dollar weakening in relation to a wide spectrum of currencies in 2020.

Debt extinguishment costs of $8 million in 2020 related to the redemption of subordinated debentures that were due in

2053.

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 decreased to $185 million in 2020 from $201 million in 2019 primarily due to a reduction in non-recurring
performance-based compensation costs which occurred in 2019 and reduced travel-related expenses due to COVID-19 in 2020.

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 $384 million in 2020 compared to $403 million in
2019. The decrease mainly relates to a reduction of aviation-related business impacted by COVID-19 in 2020.

Interest Expense. Interest expense was $151 million in 2020 compared with $153 million in 2019. During 2019, the
Company repaid at maturity $489 million aggregate principal amount of senior notes and other debt. In December 2019, the
Company issued $300 million aggregate principal amount of 5.10% subordinated debentures due 2059. In May 2020, the
Company issued $300 million aggregate principal amount of 4.00% senior notes due 2050. In September 2020, the Company
issued an additional $170 million aggregate principal amount of 4.00% senior notes due 2050 and issued $250 million
aggregate principal amount of 4.25% subordinated debentures due 2060 and repaid $300 million aggregate principal amount of
5.375% senior notes at maturity. In October 2020, the Company redeemed $350 million aggregate principal amount of 5.625%
subordinated debentures due 2053. Accordingly, the timing of the repayments of debt at maturity and redemption that took
place throughout 2019 and 2020 and issuances in 2019 and 2020 led to the decrease in interest expense for the year ended
December 31, 2020 compared to 2019. The redemption of debentures and issuance of additional debentures in 2021, as
described below in "Liquidity and Capital Resources -- Debt," are also expected to impact interest expense in 2021.

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. Due to the low
fixed maturity investment returns, 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 December 31, 2020 and 2.8 years at December 31, 2019. The Company’s investment
portfolio and investment-related assets as of December 31, 2020 were as follows:

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.

operation included a long-term ground lease in Washington D.C., an office complex in New York City, office buildings in West
Palm Beach and Palm Beach, Florida, an office building in London, 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. During the fourth quarter of 2020, the Company sold an office complex in New York City.

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, which are carried at amortized cost (net of allowance for expected credit losses),

had an amortized cost of $85 million and an aggregate fair value of $87 million at December 31, 2020. The amortized cost of
loans receivable is net of an allowance for expected credit losses of $5 million as of December 31, 2020. Loans receivable
include real estate loans of $52 million that are secured by commercial real estate located primarily in New York. Real estate
loans receivable generally earn interest at floating LIBOR-based interest rates and have maturities (inclusive of extension
options) through August 2025. Loans receivable include commercial loans of $33 million that are secured by business assets
and have fixed interest rates and floating LIBOR-based interest rates with varying maturities not exceeding 10 years.

(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.

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 approximate duration of 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 December 31, 2020 and 2.8

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

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.

To the Stockholders and 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, 2020 and 2019, 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, 2020, 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, 2020 and
2019, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31,
2020, 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, 2020, 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 18, 2021 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, 2020 were $13,784 million.

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

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. 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 operating units;
evaluating the Company’s actuarial point estimate by examining the Company actuaries’ process, and certain key
assumptions for the remaining operating units;
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, 2020, 2019 and 2018

(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 2019 and 2018 financial
statements as originally reported to conform to the presentation of the 2020 financial statements.

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 (decreased) increased net premiums written and premiums earned by $(27) million, $4 million and $(4) million
in 2020, 2019 and 2018, 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. Commissions for insurance
brokerage are generally recognized when the underlying insurance policy is effective.

(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.

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 real estate mortgage loans and bank 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 other
comprehensive income.

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.

W. R. BERKLEY CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

For the years ended December 31, 2020, 2019 and 2018

(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 2019 and 2018 financial

statements as originally reported to conform to the presentation of the 2020 financial statements.

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 (decreased) increased net premiums written and premiums earned by $(27) million, $4 million and $(4) million

in 2020, 2019 and 2018, 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. Commissions for insurance

brokerage are generally recognized when the underlying insurance policy is effective.

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

(C) Cash and cash equivalents

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.

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 real estate mortgage loans and bank 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 other
comprehensive income.

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

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 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.

corresponding credit or charge to interest income or expense. Deposit liabilities for assumed reinsurance contracts were $38
million and $41 million at December 31, 2020 and 2019, 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 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.

(E) Per share data

(K) Foreign currency

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

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

dividing net income by weighted average number of common shares outstanding during the year (including 7,767,874 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 companies. 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

64

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 $53 million, $54 million and $54 million for 2020,
2019 and 2018, 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, 2020 indicated that there were no material
impairment losses related to goodwill and other intangible assets. Intangible assets of $93 million and $99 million are included
in other assets as of December 31, 2020 and 2019, 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 $155 million, $160 million and $155 million in 2020, 2019 and 2018, respectively. Income

taxes paid were $103 million, $125 million and $186 million in 2020, 2019 and 2018, 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:

In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU")

2016-13, Financial Instruments - Credit Losses, which amended the accounting guidance for credit losses on financial
instruments. The updated guidance amended the current other-than-temporary impairment model for available for sale debt
securities by requiring the recognition of impairments relating to expected credit losses through an allowance account and limits

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 companies. 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.

the amount of credit loss to the difference between a security’s amortized cost basis and its fair value. This guidance also
applies a new current expected credit loss model for determining credit-related impairments for financial instruments measured
at amortized cost, such as reinsurance recoverables. The updated guidance was effective for reporting periods beginning after
December 15, 2019. Prior to January 1, 2020, for available for sale securities the portion of the decline in value considered to be
a credit loss (i.e., the difference between the present value of cash flows expected to be collected and the amortized cost basis of
the security) was recognized in earnings as an other-than-temporary impairment. The portion of the decline in value not
considered to be a credit loss (i.e., the difference in the present value of cash flows expected to be collected and the fair value of
the security) was recognized in other comprehensive income.

The adoption of this guidance on January 1, 2020 resulted in the recognition of an allowance for expected credit losses

in connection with operating assets (premiums and fees receivable and due from reinsurers) of $5.7 million (net of tax) and a
corresponding cumulative effect adjustment that decreased common stockholders' equity. Certain investments (primarily fixed
maturity securities available for sale) established an allowance for expected credit loss of $24.8 million (net of tax), with a
cumulative effect adjustment decreasing retained earnings by $24.8 million (net of tax) and increasing accumulated other

the amount of credit loss to the difference between a security’s amortized cost basis and its fair value. This guidance also

applies a new current expected credit loss model for determining credit-related impairments for financial instruments measured

at amortized cost, such as reinsurance recoverables. The updated guidance was effective for reporting periods beginning after

December 15, 2019. Prior to January 1, 2020, for available for sale securities the portion of the decline in value considered to be
a credit loss (i.e., the difference between the present value of cash flows expected to be collected and the amortized cost basis of

the security) was recognized in earnings as an other-than-temporary impairment. The portion of the decline in value not

considered to be a credit loss (i.e., the difference in the present value of cash flows expected to be collected and the fair value of

the security) was recognized in other comprehensive income.

The adoption of this guidance on January 1, 2020 resulted in the recognition of an allowance for expected credit losses

in connection with operating assets (premiums and fees receivable and due from reinsurers) of $5.7 million (net of tax) and a

corresponding cumulative effect adjustment that decreased common stockholders' equity. Certain investments (primarily fixed

maturity securities available for sale) established an allowance for expected credit loss of $24.8 million (net of tax), with a

cumulative effect adjustment decreasing retained earnings by $24.8 million (net of tax) and increasing accumulated other

comprehensive (loss) income ("AOCI") by $25.0 million (net of tax), resulting in $0.2 million net impact to total common

stockholders' equity.

All other accounting and reporting standards that became effective in 2020 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:

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, 2020, the Company decreased the allowance for expected credit losses utilizing

its credit loss assessment process and inputs used in its credit loss model, primarily due to the disposition of securities which
previously had an allowance recorded.

The amortized cost and fair value of fixed maturity securities at December 31, 2020, 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.

At December 31, 2020 and 2019, the fair value and carrying value of the arbitrage trading account were $341 million

and $401 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, 2020, the fair
value of long option contracts outstanding was zero (notional amount of $12.0 million) and the fair value of short option
contracts outstanding was $326 thousand (notional amount of $3.2 million). Other than with respect to the use of these trading
account securities, the Company does not make use of derivatives.

(9) Loans Receivable

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

At December 31, 2020 and December 31, 2019, loans receivable are as follows:

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 $124 million as of December 31,
2020.

The real estate loans are secured by commercial real estate primarily located in New York. These loans generally earn

interest at floating LIBOR-based interest rates and have maturities (inclusive of extension options) through August 2025. 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.

Loans receivable in non-accrual status were $0.2 million as of both December 31, 2020 and 2019.

The following table presents the rollforward of the allowance for expected credit losses for loans receivable for the

year ended December 31, 2020:

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.

In 2020, properties in operation included a long-term ground lease in Washington, D.C., an office complex in New

York City, office buildings in West Palm Beach and Palm Beach, Florida, an office building in London, U.K., and the
completed portion of a mixed-use project in Washington D.C. Properties in operation are net of accumulated depreciation and
amortization of $86,970,000 and $59,832,000 as of December 31, 2020 and 2019, respectively. Related depreciation expense
was $27,090,000 and $15,033,000 for the years ended December 31, 2020 and 2019, respectively. Future minimum rental
income expected on operating leases relating to properties in operation is $66,558,703 in 2021, $68,750,145 in 2022,
$62,144,246 in 2023, $59,270,828 in 2024, $55,265,048 in 2025 and $643,109,471 thereafter.

The Company borrowed $101,750,000 through a non-recourse loan secured by the West Palm Beach office building in

2018. The loan matures in November 2028 and carries a fixed interest rate of 4.21%. The carrying value does not reflect the
outstanding financing, but rather is reflected in subsidiary debt referenced in Note 15, Indebtedness.

A mixed-use project in Washington, D.C. has been under development in 2020 and 2019, with the completed portion

as noted above reported in properties in operation as of December 31, 2020.

During the fourth quarter of 2020, the Company sold an office complex in New York City.

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

At December 31, 2020 and December 31, 2019, loans receivable are as follows:

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

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 $124 million as of December 31,

The real estate loans are secured by commercial real estate primarily located in New York. These loans generally earn

interest at floating LIBOR-based interest rates and have maturities (inclusive of extension options) through August 2025. 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.

Loans receivable in non-accrual status were $0.2 million as of both December 31, 2020 and 2019.

The following table presents the rollforward of the allowance for expected credit losses for loans receivable for the

year ended December 31, 2020:

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.

(1)  The net realized gains or losses on investment sales represent the total gains or losses from the purchase dates of the equity
securities. The change in unrealized gains consists of two components: (i) the reversal of the gain or loss recognized in previous
periods on equity securities sold and (ii) the change in unrealized gain or loss resulting from mark-to-market adjustments on
equity securities still held.

(2) For 2020, net investment gains on real estate includes an $105 million gain from the sale of a New York City complex that
occurred during the fourth quarter.

(3) The inclusion of the allowance for expected credit losses on investments commenced on January 1, 2020 due to the adoption
of ASU 2016-13. See Note 1 for more details.

Substantially all of the securities in an unrealized loss position are rated investment grade, except for the securities in

the foreign government classification. In general, fair value in all classifications were negatively affected by market disruptions
caused, in significant part, by COVID-19. 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.

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 following tables present the assets and liabilities measured at fair value as of December 31, 2020 and 2019 by

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.

For the year ended December 31, 2020, a fixed maturity security was transferred from Level 2 into Level 3 as a result

of observable valuation inputs no longer being available. For the year ended December 31, 2019, there were two common
stocks transferred into Level 3 in the arbitrage trading account where publicly traded prices were no longer available, and both
were sold by year end.

For the year ended December 31, 2020, a fixed maturity security was transferred from Level 2 into Level 3 as a result

of observable valuation inputs no longer being available. For the year ended December 31, 2019, there were two common

stocks transferred into Level 3 in the arbitrage trading account where publicly traded prices were no longer available, and both

were sold by year end.

The most commonly used claim count method is by event. Most of the Company's operating units 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, an operating unit 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 automobile or transportation exposure.

(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 operating unit, the Company purchases specific additional reinsurance to supplement the above programs.

The Company had a current tax net payable of $35.4 million and net receivable of $13.4 million at December 31, 2020

and 2019, respectively. At December 31, 2020, the Company had foreign net operating loss carryforwards of $7.7 million that
expire beginning in 2027, and an additional $305.4 million that have no expiration date. At December 31, 2020, the Company
had a valuation allowance of $79.5 million, as compared to $33.3 million at December 31, 2019. 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 tax returns has closed for calendar year
2016 and all years through December 31, 2013.

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 $111

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.

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 $200 million at December 31, 2020.

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, 2020, BIC’s Total Adjusted Capital of $5.989 billion
was 388% 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 7,767,874 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).

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.

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).

The amount of dividends paid is dependent upon factors such as the receipt of dividends from our subsidiaries, our

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

Contractual maturities of the Company’s future minimum lease payments are as follows:

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.

At December 31, 2020, the Company had commitments to invest up to $124 million and $200 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:

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, 2020, 7,519,447 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
