TO OUR SHAREHOLDERS

2023 was an exceptional year of growth and 

success at Arch. For the second consecutive 

year, we surpassed previous milestones in 

premium growth and underwriting income 

while further establishing our leadership 

position in the specialty insurance sector. Our 

shareholders were rewarded with an 18.3% 

share price increase and a net income return on 

average common equity of 29.7%.

Underwriting Results
At Arch, underwriting compensation is aligned with shareholder 

results, meaning the profitability of the business is what ultimately 

drives underwriting decisions. This is key to our success. Therefore, 

whether we are operating in a hard or soft market, we maintain a 

principled underwriting approach focused on pricing adequacy 

and risk-adjusted returns. Our focus on underwriting profitability is 

reflected in the $2.6 billion* of underwriting income generated across 

our segments, a 45% increase from 2022. 

Along with our focus on underwriting returns, we take a long-term view 

of risk that dictates a prudent approach to reserving. At Arch, we protect 

shareholder capital by conservatively setting our reserves based on 

a comprehensive view of historical losses and actuarial models and 

then let the reserves age until there is enough data to more precisely 

determine the ultimate loss. For us, the adage holds true: Recognize 

bad news quickly and good news over time. Fortunately, for Arch and 

our shareholders, we have good news to report.

Segment Performance
Arch is a diversified enterprise. That enables us to manage the 

insurance cycle by dynamically allocating capital 

 across and 

within our business segments 

 to the opportunities with the 

—

—

greatest expected returns. Since the emergence of the current hard 

market cycle, we have increasingly deployed capital into our P&C 

segments, which offer tremendous growth opportunities combined

with solid risk-adjusted returns.

INSURANCE 
The Insurance group wrote $5.9 billion of net premium in 2023, a 17% 

increase from 2022, while delivering $450 million of underwriting 

income — more than double the $224 million produced in 2022. 

*  We use non-GAAP financial measures in this report. The first mention of each non-GAAP 

financial measure is referenced by an asterisk (*). See Additional Information for a 

  reconciliation to the most comparable GAAP financial measures.

Premium growth in 2023 came from a diverse mix of products including 
Property, Energy, Marine and Aviation, Construction and National 

Accounts, and Programs. I’m also pleased to note the increasing 

market leadership and influence of the Insurance team, which received 

a significant number of accolades last year including, importantly, 

several awards recognizing our commitment to broker partners. 

REINSURANCE 
For the second consecutive year, our Reinsurance segment grew 

the most of our three underwriting segments. Net premiums written 

(NPW) were $6.6 billion in 2023, a 33% increase from 2022. 

Underwriting income increased to $1.1 billion, an impressive 249% 

jump from 2022 and evidence of our ability to rapidly increase our 

capacity to meet client demands around the world. Growth in our 

Reinsurance book was broad-based, reflecting improved market 

conditions, the expertise and leadership of our talented team and a 

reduction in capacity from our competition. 

MORTGAGE 
The Mortgage segment remained a global leader in acquiring, 

managing and syndicating mortgage credit risk and has become a 

reliable “earnings engine” for our shareholders. In 2023, the segment 

generated $1.1 billion of underwriting income while writing  

$1.1 billion of NPW, an excellent performance despite a housing market 

with lower new originations amid tight supply. Persistency of coverage 

remained strong as higher mortgage rates reduced the incentive for 

most homeowners to sell their homes or refinance their mortgages. 

The credit quality of homebuyers with loans we insure remains 

very strong, and the discipline of the overall mortgage market is 

reassuring. Our focus on credit quality and profitability over volume 

helps ensure a well-constructed portfolio that can deliver profitable 

results under different economic scenarios.

Investment Results and Cash Flow
Fueled by the extraordinary premium growth in our P&C segments, 

investable assets, or “the float,” increased to $34.6 billion at the end of 

2023, a 23% increase from the $28.1 billion at the end of 2022. Net 

investment income exceeded $1.0 billion for the first time in our history, 

a 106% increase from 2022 on a per-share basis as higher investment 

yields continue to earn into our results. 

We maintain a cautious approach toward duration and credit risk. At 

the end of 2023, approximately 76% of the portfolio was invested in 

fixed maturity and short-term securities with an average credit quality 

of “AA-/Aa3,” and our overall portfolio had an average effective duration 

of 2.91 years.

Capital Management
We take pride in our reputation as an effective allocator of capital, and 

we carefully consider all opportunities when deploying the capital 

entrusted to us. In 2023, we strategically deployed capital into our P&C 

segments to fund growth we believe will generate excellent returns. 

We maintain a strong balance sheet and a prudent approach to 

reserving that allows us to support our client obligations and provides 

us with the financial flexibility to seize compelling market opportunities 

that arise. The ratio of debt and preferred shares to total capital was 

16.9% at the end of 2023, indicating substantial liquidity.

Arch’s People
Our people are our competitive advantage. The knowledge, hard work, 

innovation and dedication to client needs of more than 6,400 Arch 

employees help sustain Arch’s high performance. As our company 

continues to grow, we maintain a focus on building strength and talent 

density across our teams. By enabling our employees to lead with 

purpose and engage in thoughtful collaboration, Arch cultivates a 

workplace where individuals can connect, grow and build a fulfilling 

and rewarding career. 

In 2023, we completed our biennial all-employee survey, which 

gathered critical feedback from the people who know us best. I’m 

pleased to report our employee engagement score was 88% (10 points 

above the industry average), up four points from our first all-employee 

survey in 2019.

Our 2023 anonymous employee survey was conducted by Workforce Science 
Associates (WSA). Survey results provided represent the percentages of those 
who responded.

The last few years have seen us grow into a market leader as we strive 

to be the first choice for clients, shareholders, employees and our 

communities. Our progress has been impressive. Of course, as anyone 

knows, the hardest part of becoming a leader is remaining a leader. 

Building upon this success is our charge for 2024 and beyond. 

Our ability to act swiftly at the outset of the hard market established 

Arch as a compelling partner. While we’ve been working to maximize 

today’s opportunity, we’re also focused on the future. Over the past 

several years we’ve made meaningful enhancements to our platform, 

including entering new lines, expanding into new geographies and 

making investments into new underwriting teams, technology and data 

analytics — all with an eye on creating additional shareholder value.

Collaborative leadership, incessant curiosity and a willingness to 

challenge one another are crucial aspects of our culture and part of what 

allows us to maintain the discipline and institutional knowledge needed 

to navigate market cycles to deliver consistent and profitable results. 

I want to thank Arch employees for their work in 2023 and their 

passion to help our clients, employees, investors and communities 

achieve their greatest potential. I also want to thank our distributors, 

clients and other partners for choosing to do business with Arch. And, 

finally, thank you to our shareholders for your continued confidence 

and support.

the Mortgage segment to focus its efforts on the best relative returns and to consistently serve as an earnings engine for Arch. With operations in 

the U.S., Australia, Europe and Bermuda, Arch MI is well positioned to navigate evolving housing market conditions around the world.

We remain committed to transparency and sharing our ESG performance through our Sustainability Report, Sustainability Accounting 

Environmental, Social 

and Governance ESG

Standards Board (SASB) Report and Task Force on Climate-related Financial Disclosures (TCFD) Report. Our ESG strategy encompasses five 

impact areas that support and drive our ESG initiatives:

BUSINESS

OPERATIONS

INVESTMENTS

PEOPLE

COMMUNITIES

We offer services and insurance 
coverages that support our 
clients through major loss and 
improve their resiliency; we 
integrate ESG factors into our 
underwriting to reduce risk and 
capture opportunities for 
stakeholder benefit.

We actively manage ESG 
risks and embed compliance, 
transparency, cybersecurity 
and resilience across all areas 
of our operations, protecting 
our people and customers who 
entrust us with their personal 
information and 
business interests.

We believe incorporating 
certain nonfinancial ESG 
factors into investment 
selection and risk 
management can potentially 
enhance long-term 
investment returns.

We are committed to 
investing in the personal and 
professional success of our 
employees and creating 
long-term sustainable growth 
for our organization.

Striving to make a meaningful 
impact by investing in our 
communities is ingrained in 
Arch’s core Values, woven 
into the fabric of our 
corporate culture.

Our Business 
Our specialized insurance coverages and services protect our clients, allow 
them to rebuild after major losses and help families build wealth through 
homeownership. Through our businesses, we: 
	

Employ underwriting initiatives to improve resiliency and transition to a 
lower carbon economy.

	

Take a strategic approach to enterprise risk management, including 
integrating climate risk.

	

Offer products and customer-oriented solutions that help build safer, 
stronger and more inclusive communities.

Our Operations 
We are taking steps to source sustainable products and services and reduce 
our carbon footprint around the globe. Across our enterprise:
	

We are committed to embedding environmental sustainability into our 
workplaces’ design, function and maintenance to increase energy efficiency.

	

144 vendors acknowledged our Supplier Code of Conduct where we ask 
vendors to align with our Values, ethics and ESG standards. 

Our Investing
We believe integrating ESG factors into investment analysis may contribute 
to improved returns, reduces risk over the long term and aligns with our 
stakeholders’ best interests. We recognize the importance, relevance and 
significance of assessing ESG topics in the sustainability performance of 
the entities in which we invest while aiming to deliver total return for Arch. 
Investments as of Dec. 31, 2023, include:
	

$919 million, 3% of assets under management (AUM), are in investments 
with an ESG focus. 

	

$10.3 billion, 30% of AUM, are with asset owners or managers that are 
signatories of the United Nations Principles for Responsible Investment.

Our People 
At Arch, our people are our business. Arch enhances the employee experience 
by advancing our diversity and inclusion (D&I) efforts, sustaining a work 
environment where everyone can thrive, and providing employees with resources 
and opportunities for professional development. Some highlights include: 
	

26% of employees participate in our employee-led networks. 

	

We increased our inclusive benefit offerings to attract and retain talent 
including a new military leave benefit and a progressive salary-based 
premium framework for medical plans for U.S.-based employees resulting 
in more than 65% of employees benefitting from decreased premiums for 
the same coverage. 

	

92% of Arch employees who participated in our biennial all-employee 
—
 above the industry average and 
survey were proud to work for Arch 
consistent with prior surveys.

Our Communities 
We are dedicated to making a difference in the communities where we live and 
work through philanthropic and volunteer efforts. Last year: 
	

Arch donated $7 million to charitable organizations and has donated a 
total of $22 million since 2020.

	

The Arch Group Foundation awarded grants of over $1 million to more 
than 30 nonprofits aligned with Arch’s giving priorities — accessible safe 
housing; academic and career success; environmental resilience; and 
healthy, thriving societies. 

	

Through our matching gift program, employees donated more than  
$2 million to organizations that aligned with their interests. Arch provided                      
nearly $3 million in matching gifts, more than doubling the power of our 
employees’ generosity.

	

Employees donated over 12,000 hours of volunteer time off in 2023.

Additional Information

This document includes the use of certain non-GAAP financial measures as defined in Regulation G. See “Management’s Discussion and Analysis of Financial Condition and Results 
of Operations — Comment on Non-GAAP Financial Measures” on pages 67–69 of the Company’s Annual Report on Form 10-K, filed with the SEC on Feb. 23, 2024 (the “2023 
Annual Report”), which accompanies this letter. Throughout this document, we present our operations in the way we believe will be the most meaningful and useful to investors, 
analysts, rating agencies and others who use our financial information in evaluating the performance of our company. We believe that these non-GAAP financial measures, which 
may be defined differently by other companies, are important for an understanding of our overall results of operations and financial condition. However, they should not be viewed 
as a substitute for measures determined in accordance with GAAP.

After-tax operating income available to Arch common shareholders is defined as net income available to Arch common shareholders, excluding net realized gains or losses 
(which includes changes in the allowance for credit losses on financial assets and net impairment losses recognized in earnings), equity in net income or loss of investment funds 
accounted for using the equity method, net foreign exchange gains or losses, transaction costs and other, and income taxes (which for the 2023 fourth quarter includes a one-time 
deferred tax benefit related to the enactment of Bermuda’s new corporate income tax).

Operating return on average common equity represents after-tax operating income available to Arch common shareholders divided by average common shareholders’ equity 
during the period. Management uses operating return on average common equity as a key measure of the return generated to our common shareholders.  

The following table summarizes the Company’s consolidated financial data, including a reconciliation of net income (loss) available to Arch common shareholders to after-tax 
operating income (loss) available to Arch common shareholders.

Underwriting income represents the pre-tax profitability of our underwriting operations and includes net premiums earned plus other underwriting income, less losses and 
loss adjustment expenses, acquisition expenses and other operating expenses. Other operating expenses include those operating expenses that are incremental and/or directly 
attributable to our individual underwriting operations. Underwriting income or loss does not incorporate items included in the corporate segment. While these measures are 
presented in note 4, “Segment Information,” on pages 114-120 to the consolidated financial statements in our 2023 Annual Report, they are considered non-GAAP financial 
measures when presented elsewhere on a consolidated basis.

Combined ratio excluding catastrophic activity and prior year development for the insurance and reinsurance segments are non-GAAP financial measures as defined in 
Regulation G. The reconciliation of such measures to the combined ratio (the most directly comparable GAAP financial measure) in accordance with Regulation G are shown in the 
table below. The Company’s management utilizes the adjusted combined ratios excluding current accident year catastrophic events and favorable or adverse development in prior 
year loss reserves in its analysis of the underwriting performance of each of its underwriting segments. 

Underwriting ratios:

Loss ratio

Acquisition expense ratio

Other operating expense ratio

Combined ratio

Catastrophic activity and prior year development:

OUR COMPANY

General

reinsurance  and  mortgage 

Arch Capital is a publicly listed Bermuda exempted company

2023  and  is  part  of  the  S&P  500  index.  Arch  provides 
insurance  on  a 
insurance, 
worldwide  basis  through  its  wholly  owned  subsidiaries. 
While we are positioned to provide a full range of property, 
casualty  and  mortgage  insurance  and  reinsurance  lines,  we 
focus on writing specialty lines of insurance and reinsurance. 
For  2023,  we  wrote  $13.5  billion  of  net  premiums  and 
reported net income available to Arch common shareholders 
of  $4.4  billion.  Book  value  per  share  was  $46.94  at 
December  31,  2023,  compared  to  $32.62  per  share  at 
December 31, 2022.

Arch  Capital’s  registered  office  is  located  at  Clarendon 
House,  2  Church  Street,  Hamilton  HM  11,  Bermuda 
(telephone  number:  (441)  295-1422),  and  its  principal

Our History

Arch Capital was formed in September 2000 and became the 
sole  shareholder  of  Arch  Capital  Group  (U.S.)  Inc.  (“Arch-
U.S.”)  pursuant  to  an  internal  reorganization  transaction 
completed in November 2000. In October 2001, Arch Capital 
launched an underwriting initiative to meet current and future 
demand in the global insurance and reinsurance markets that 
included  the  recruitment  of  new  management  teams  and  an 
equity  capital  infusion  of  $763.2  million,  which  created  a 
strong  capital  base  that  was  unencumbered  by  significant 
pre-2002  risks.  Since  then,  we  have  attracted  a  proven 
management  team  with  extensive  industry  experience  and 
continued  to  build  our  global  underwriting  platform  for  our 
insurance, reinsurance and mortgage insurance businesses.

Our insurance underwriting platform initially consisted of our 
Bermuda and U.S. operations, followed by the establishment 
of our United Kingdom-based carrier, Arch Insurance (U.K.) 
Limited  (“Arch  Insurance  (U.K.)”)  in  2004  and  Canadian 
operations  in  2005.  In  2009,  we  established  a  managing 
agency  and  syndicate  at  Lloyd’s  of  London  (“Lloyd’s”)  and 
significantly expanded our U.K. presence in 2019 through the 
acquisition  of  Barbican  Group  Holdings  Limited  (“Barbican 
Holdings”)  and  its  subsidiaries  (collectively,  “Barbican”). 
Our U.S. platform grew with the 2018 acquisition of McNeil 
&  Company,  Inc.  (“McNeil”),  a  U.S.  nationwide  leader  in 
specialized  risk  management  and  program  administration. 
See  “Operations—Insurance  Operations”  for  further  details 
on our insurance operations.

Our  reinsurance  underwriting  platform  initially  consisted  of 
Arch  Reinsurance  Ltd.  in  Bermuda  (“Arch  Re  Bermuda”) 
and Arch Reinsurance Company (“Arch Re U.S.”), our U.S.-
licensed  reinsurer.  Our  European  reinsurance  operations 
commenced  in  2006  in  Zurich,  Switzerland  followed  by  the 
formation  of  a  Danish  underwriting  agency  in  2007.  In 
addition  to  the  U.S.  reinsurance  treaty  activities  of  Arch  Re 
U.S.,  we  launched  our  property  facultative  reinsurance 
underwriting  operations  in  2007,  which  underwrite  in  the 
U.S.,  Canada  and  Europe.  In  2008,  we  formed  Arch 
Reinsurance  Europe  Designated  Activity  Company  (“Arch 
reinsurance  company 
Ireland-based 
Re  Europe”),  our

was  established  in  2014  and  expanded  greatly  in  2016 
through  the  acquisition  of  United  Guaranty  Corporation

mortgage insurance products and services to the U.S. market. 
These  operations  include  providers  which  are  also  approved 
as  eligible  mortgage  insurers  by  Federal  National  Mortgage 
Association  (“Fannie  Mae”)  and  Federal  Home  Loan 
Mortgage  Corporation  (“Freddie  Mac”),  each  a  GSE.  The 
mortgage operations also include participation in GSE credit 
risk-sharing  transactions  and  direct  mortgage  insurance  to 
U.S. mortgage lenders with respect to mortgages that lenders 
intend  to  retain  in  portfolio  or  include  in  non-agency 
securitizations

business  is  written  through  our  Ireland-based  carrier,  Arch 
Insurance  (EU)  Designated  Activity  Company  (“Arch 
Insurance  (EU)”),  which  was  authorized  in  2011  to  provide 
mortgage  insurance  products  and  services  to  the  European 
and U.K. markets. In 2019, Arch LMI Pty Ltd. (“Arch LMI”) 
was  authorized  by  the  Australian  Prudential  Regulation 
Authority (“APRA”) to write lenders’ mortgage insurance on 
a  direct  basis  in  Australia.  We  expanded  our  presence  in 
Australia  in  August  2021  by  acquiring  Westpac  Lenders 
Mortgage Insurance Limited, another APRA approved writer 
of  lenders’  mortgage  insurance,  which  has  since  been 
renamed  Arch  Lenders  Mortgage  Indemnity  Ltd.  (“Arch 
Indemnity”).  In  December  2022,  we  converted  Arch  LMI 
into  a  services  company  for  our  Australian  LMI  operations

The  Board  of  Directors  of  Arch  Capital  (the  “Board”)  has 
authorized  the  investment  in  Arch  Capital’s  common  shares 
through  a  share  repurchase  program.  Repurchases  under  the 
share repurchase program may be effected from time to time 
in  open  market  or  privately  negotiated  transactions  through 
December  31,  2024.  Since  the  inception  of  the  share 
repurchase program in February 2007 through December 31, 
2023,  Arch  Capital  has  repurchased  433.6  million  common 
shares  for  an  aggregate  purchase  price  of  $5.9  billion.  At 
December  31,  2023,  the  total  remaining  authorization  under 
the  share  repurchase  program  was  $1.0  billion.  The  timing 
and amount of the repurchase transactions under this program 
will  depend  on  a  variety  of  factors,  including  results  of 
operations,  market  conditions  and  the  development  of  the 
economy,  as  well  as  other  factors.  We  will  consider  share 
repurchases on an opportunistic basis. During the 2023 fiscal 
year,  we  did  not  repurchase  any  shares  under  our  share 
repurchase program.

where  it  is  not  yet  admitted.  Our  insurance  group  also 
operates  McNeil,  a  specialized  risk  manager  and  a  program 
administrator based in Cortland, New York. The headquarters 
for our insurance group’s U.S. support operations (excluding 
underwriting  units)  are  in  Jersey  City,  New  Jersey.  The 
insurance  group  has  offices  throughout  the  U.S.,  including 
five regional offices located in Alpharetta, Georgia; Chicago, 
Illinois;  New  York,  New  York;  San  Francisco,  California; 
Dallas, Texas and additional branch offices.

Our  insurance  operations  in  Canada  are  conducted  through 
Arch  Insurance  Canada  Ltd.  (“Arch  Insurance  Canada”),  a 
Canada  domestic  company  which  is  authorized  in  all 
Canadian provinces and territories. Arch Insurance Canada is 
headquartered in Toronto, Ontario. 

In  2019,  Arch  Insurance  (EU),  based  in  Dublin,  Ireland, 
received  authorization  from  the  Central  Bank  of  Ireland 
(“CBI”)  to  expand  its  authorized  classes  of  business  as  part 
of  our  plan  to  address  the  U.K.’s  departure  from  the 
European  Union  (“Brexit”).  At  the  end  of  2020,  Arch 
Insurance  (U.K.)  received  court  approval  in  the  U.K.  to 
transfer  its  legacy  book  of  business  written  in  the  European 
Economic Area (“EEA”) to Arch Insurance (EU) under Part 
VII  of  the  U.K.  Financial  Services  and  Markets  Act  2000. 
From  January  2020,  all  of  the  insurance  business  in  the 
European  Union  (“EU”)  previously  written  by  Arch 
Insurance  (U.K.)  is  now  written  through  Arch  Insurance 
(EU).  Arch  Insurance  (EU)  has  branches  in  Italy,  France, 
Spain and the U.K. 

We conduct insurance operations on several platforms in the 
U.K.,  including  Arch  Insurance  (U.K.)  and  our  Lloyd’s 
syndicates:  Arch  Syndicate  2012  (“Arch  Syndicate  2012”) 
and  Arch  Syndicate  1955  (“Arch  Syndicate  1955”  and, 
together  with  Arch  Syndicate  2012,  our  “Lloyd’s 
Syndicates”). Arch Managing Agency Limited (“AMAL”) is 
the  managing  agent  of  our  Lloyd’s  Syndicates.  These 
operations provide us access to Lloyd’s extensive distribution 
network  and  worldwide  licenses.  AMAL  also  acts  as 
managing  agent  for  third  party  members  of  Arch  Syndicate 

1955.  Arch  Underwriting  at  Lloyd’s  (Australia)  Pty  Ltd, 
based  in  Sydney,  Australia,  is  a  Lloyd’s  services  company 
which  underwrites  exclusively  for  our  Lloyd’s  Syndicates. 
Collectively, the U.K. insurance operations are referred to as 
“Arch U.K.” Arch U.K. conducts its operations from London 
and other locations in the U.K. In December 2023, we signed 
an  agreement  for  the  sale  of  Castel  Underwriting  Agencies 
Limited,  a  managing  general  agency  in  the  U.K.  that  we 
acquired  as  part  of  the  Barbican  acquisition.  The  sale  is 
expected  to  close  in  the  first  half  of  2024,  subject  to 
regulatory approvals and other closing conditions.

Strategy. Our insurance group’s strategy is to operate in lines 
of  business  in  which  underwriting  expertise  can  make  a 
meaningful  difference  in  operating  results.  The  insurance 
group  focuses  on  talent-intensive  rather  than  labor-intensive 
business and seeks to operate profitably (on both a gross and 
net  basis)  across  all  of  its  product  lines.  To  achieve  these 
objectives, our insurance group’s operating principles are to:

•

its 

that 

group 

believes 

Capitalize on profitable underwriting opportunities. Our 
insurance 
experienced 
management  and  underwriting  teams  are  positioned  to 
locate  and  identify  business  with  attractive  risk/reward 
characteristics.  As  profitable  underwriting  opportunities 
are identified, our insurance group will continue to grow 
its product portfolio in order to take advantage of market 
trends.  This  includes  adding  underwriting  and  other 
professionals with specific expertise in specialty lines of 
insurance.

•  Centralize responsibility for underwriting. Our insurance 
group  consists  of  a  range  of  product  lines.  The 
underwriting  executive  in  charge  of  each  product  line 
oversees  all  aspects  of 
the  underwriting  product 
development  process  within  such  product  line.  Our 
insurance group believes that centralizing the control of 
such  product  line  with  the  respective  underwriting 
executive  allows  for  close  management  of  underwriting 
and  creates  clear  accountability  for  results.  Our  U.S. 
insurance  group  has  five  regional  offices,  and  the 
executive 
is  primarily 
responsible  for  all  aspects  of 
the  marketing  and 
distribution of our insurance group’s products, including 
the  management  of  broker  and  other  producer 
relationships  in  such  executive’s  respective  region.  In 
our  non-U.S.  offices,  a  similar  philosophy  is  observed, 
with  responsibility  for  the  management  of  each  product 
line  residing  with  the  senior  underwriting  executive  in 
charge of such product line.

in  charge  of  each  region 

•  Maintain  a  disciplined  underwriting  philosophy.  Our 
insurance group’s underwriting philosophy is to generate 
an underwriting profit through prudent risk selection and 
proper pricing. Our insurance group believes that the key 
to  this  approach  is  adherence  to  uniform  underwriting

standards  across  all  types  of  business.  Our  insurance 
the 
group’s  senior  management  closely  monitors 
underwriting process.

•  Focus  on  providing  superior  claims  management.  Our 
insurance  group  believes  that  claims  handling  is  an 
integral  component  of  credibility  in  the  market  for 
insurance  products.  We  believe  our  ability  to  handle 
claims  expeditiously  and  satisfactorily  is  a  key  to  our 
success.  Our  insurance  group  employs  experienced 
claims  professionals  and  also  utilizes  experienced 
external  claims  managers  (third  party  administrators) 
where appropriate.

•  Promote and utilize an efficient distribution system. Our 
insurance  group  believes  that  promoting  and  utilizing  a 
multi-channel  distribution  system  provides  efficient 
access  to  its  broad  customer  base.  We  work  with  select 
international,  national  and  regional  retail  and  wholesale 
brokers  and  leading  managing  general  agencies  and 
program  administrators,  including  McNeil,  to  distribute 
our insurance products. The Arch U.K. regional division 
has a retail distribution network in the U.K.

•

Grow  strategic  partnerships  or  acquire  strategic 
businesses  in  stable  and  niche  areas.  Our  insurance 
group aims to build more integrated long-term alignment 
with  strategic  partners  offering  superior  access  to  niche 
opportunities,  quality  scalable  businesses,  or  lines  with 
reliable  defensive  qualities.  We  may  grow  existing 
partnerships or look to acquire businesses which further 
this strategy.

Our  insurance  group  writes  business  in  the  U.S.  on  both  a 
U.S.  admitted  and  U.S.  non-admitted  basis.  Our  insurance 
group focuses on various specialty lines, as described in note 
4,  “Segment  Information,”  to  our  consolidated  financial 
statements in Item 8.

insurance 

Philosophy.  Our 

group’s 
Underwriting 
underwriting philosophy is to generate an underwriting profit 
(on both a gross and net basis) through prudent risk selection 
and  proper  pricing  across  all  types  of  business.  One  key  to 
this  philosophy  is  the  adherence  to  uniform  underwriting 
standards  across  each  product  line  that  focuses  on  the 
following:

• 

• 

• 

• 

• 
• 

risk selection;

desired attachment point; 

limits and retention management; 

due  diligence,  including  financial  condition,  claims 
history,  management,  and  product,  class  and  territorial 
exposure; 
underwriting authority and appropriate approvals; and 
collaborative decision making. 

Marketing.  Our  insurance  group’s  products  are  marketed 
principally through a group of licensed independent retail and 
wholesale  brokers.  Clients  (insureds)  are  referred  to  our 
insurance  group  through  a  large  number  of  international, 
national  and  regional  brokers  and  captive  managers  who 
receive  from  the  insured  or  insurer  a  set  fee  or  brokerage 
commission usually equal to a percentage of gross premiums. 
Our  insurance  group  may  enter  into  contingent  commission 
arrangements with some brokers that provide for the payment 
of  additional  commissions  based  on  volume  or  profitability 
of  business.  Currently,  some  of  our  contracts  with  brokers 
provide for additional commissions based on volume. It is the 
practice  for  the  brokers  and  producers  to  make  the  client 
aware of any contingent commission arrangements that may 
be  in  place  with  us.  We  have  also  entered  into  service 
agreements  with  select  international  brokers  that  provide 
access to their proprietary industry analytics. In general, our 
insurance  group  has  no  implied  or  explicit  commitments  to 
accept  business  from  any  particular  broker  and  neither 
brokers nor any other third parties have the authority to bind 
our  insurance  group,  except  in  the  case  where  underwriting 
authority  may  be  delegated  contractually  to  select  program 
administrators. Such administrators are subject to a financial 
and  operational  due  diligence  review  prior  to  any  such 
delegation  of  authority  and  ongoing  reviews  and  audits  are 
carried  out  as  deemed  necessary  by  our  insurance  group  to 
assure  the  continuing  integrity  of  underwriting  and  related 
business  operations.  See  “Risk  Factors—Risks  Relating  to 
Our  Industry,  Business  and  Operations—We  could  be 
materially  adversely  affected  to  the  extent  that  important 
third parties with whom we do business do not adequately or 
appropriately  manage  their  risks,  commit  fraud  or  otherwise 
breach  obligations  owed  to  us.”  For  information  on  major 
brokers,  see  note  18,  “Commitments  and  Contingencies—
Concentrations of Credit Risk,” to our consolidated financial 
statements in Item 8.

Risk Management and Reinsurance. In the normal course of 
business,  our  insurance  group  may  cede  a  portion  of  its 
premium  on  a  quota  share  or  excess  of  loss  basis  through 
treaty  or  facultative  reinsurance  agreements.  Reinsurance 
arrangements  do  not  relieve  our  insurance  group  from  its 
primary obligations to insureds. Reinsurance recoverables are 
recorded  as  assets,  predicated  on  the  reinsurers’  ability  to 
meet  their  obligations  under  the  reinsurance  agreements.  If 
the reinsurers are unable to satisfy their obligations under the 
agreements,  our  insurance  subsidiaries  would  be  liable  for 
such defaulted amounts. Our principal insurance subsidiaries, 
with  oversight  by  a  group-wide  reinsurance  steering 
committee  (“RSC”),  are  selective  with  regard  to  reinsurers, 
seeking to place reinsurance with only those reinsurers which 
meet  and  maintain  specific  standards  of  established  criteria 
for  financial  strength.  The  RSC  evaluates  the  financial 
viability of its reinsurers through financial analysis, research 
and  review  of  rating  agencies’  reports  and  also  monitors

For  catastrophe-exposed  insurance  business,  our  insurance 
group  seeks  to  limit  the  amount  of  exposure  to  catastrophic 
losses  it  assumes  through  a  combination  of  managing 
aggregate  limits,  underwriting  guidelines  and  reinsurance.

In December 2022, Arch Group Reinsurance Ltd. (“AGRL”) 
was  registered  as  a  Class  3A  general  business  insurer 
carrying  on  affiliated  reinsurance  business  pursuant  to  the 
Insurance Act of 1978 of Bermuda. AGRL, a wholly-owned 
subsidiary  of  Arch-U.S.,  was  established  to  provide  internal 
quota  share  reinsurance  covering  certain  U.S.  lines  of 
business. AGRL is a U.S. taxpayer through a section 953(d) 
voluntary election under the Internal Revenue Code of 1986,

Strategy. Our reinsurance group’s strategy is to capitalize on

operational flexibility to offer multiple products through our 
operations.  The  reinsurance  group’s  operating  principles  are 
to:

C  long-term  insurer  and  is  headquartered  in  Hamilton,

“reciprocal  jurisdiction  reinsurer,”  which  allows  ceding

trends.  Our  reinsurance  group  believes  that  its  existing 
platforms  in  Bermuda,  the  U.S.,  U.K.,  Europe  and 
Canada,  broad  underwriting  expertise  and  substantial 
capital  facilitate  adjustments  to  its  mix  of  business 
geographically  and  by  line  and  type  of  coverage.  Our 
reinsurance  group  believes  that  this  flexibility  allows  it 
to  participate  in  those  market  opportunities  that  provide 
the greatest potential for underwriting profitability.

• Maintain  a  low  cost  structure.  Our  reinsurance  group 
believes  that  maintaining  tight  control  over  its  staffing

they can underwrite and process the business efficiently. The 
reinsurance  group’s  property  facultative  operations  write 
reinsurance  on  a  facultative  basis  whereby  they  assume  part 
of  the  risk  under  primarily  single  insurance  contracts. 
Facultative  reinsurance  is  typically  purchased  by  ceding 
companies  for 
their 
reinsurance  treaties,  for  unusual  risks  or  for  amounts  in 
excess of the limits on their reinsurance treaties.

the  reinsurance  group,  please  refer  to  note  4,  “Segment 
Information,” to our consolidated financial statements in Item 
8.

Underwriting  Philosophy.  Our  reinsurance  group  employs  a 
disciplined,  analytical  approach  to  underwriting  reinsurance 
risks  that  is  designed  to  specify  an  adequate  premium  for  a 
given  exposure  commensurate  with  the  amount  of  capital  it 
anticipates  placing  at  risk.  A  number  of  our  reinsurance 
group’s underwriters are also actuaries. It is our reinsurance 
group’s  belief  that  employing  actuaries  on  the  front-end  of 
the underwriting process gives it an advantage in evaluating 
risks and constructing a high quality book of business.

As  part  of  the  underwriting  process,  our  reinsurance  group 
typically assesses a variety of factors, including:

•

•

adequacy  of  underlying  rates  for  a  specific  class  of 
business and territory;

the reputation of the proposed cedent and the likelihood 
of establishing a long-term relationship with the cedent, 
the  geographic  area  in  which  the  cedent  does  business, 
together  with 
its  catastrophe  exposures,  and  our 
aggregate exposures in that area;

•

•

•

historical  loss  data  for  the  cedent  and,  where  available, 
for  the  industry  as  a  whole  in  the  relevant  regions,  in 
order  to  compare  the  cedent’s  historical  loss  experience 
to industry averages; 

projections of future loss frequency and severity; and 

the perceived financial strength of the cedent. 

Marketing.  Our  reinsurance  group  generally  markets  its 
reinsurance  products  through  brokers,  except  our  property 
facultative reinsurance group, which generally deals directly 
with the ceding companies. Brokers do not have the authority 
to  bind  our  reinsurance  group  with  respect  to  reinsurance 
agreements,  nor  does  our  reinsurance  group  commit  in 
advance  to  accept  any  portion  of  the  business  that  brokers 
submit  to  them.  Our  reinsurance  group  generally  pays 
brokerage fees to brokers based on negotiated percentages of 
the premiums written through such brokers. For information 
on  major  brokers,  see  note  18,  “Commitments  and 
Contingencies—Concentrations  of  Credit  Risk,”  to  our 
consolidated financial statements in Item 8.

Risk  Management  and  Retrocession.  Our  reinsurance  group 
currently  purchases  a  combination  of  per  event  excess  of 
loss,  per  risk  excess  of  loss,  proportional  retrocessional 
agreements  and  other  structures  that  are  available  in  the 
market. Such arrangements reduce the effect of individual or 
aggregate  losses  on,  and  in  certain  cases  may  also  increase 
the  underwriting  capacity  of,  our  reinsurance  group.  Our 
reinsurance group will continue to evaluate its retrocessional 
requirements  based  on  its  net  appetite  for  risk.  See  note  8, 
“Reinsurance,”  to  our  consolidated  financial  statements  in 
Item 8.

exposed 

catastrophe 

For 
reinsurance  business,  our 
reinsurance  group  seeks  to  limit  the  amount  of  exposure  it 
assumes  from  any  one  reinsured  and  the  amount  of  the 
aggregate exposure to catastrophe losses from a single event 
in  any  one  geographic  zone.  For  a  discussion  of  our  risk 
management  policies,  see  “Management’s  Discussion  and 
Analysis of Financial Condition and Results of Operations—
Summary  of  Critical  Accounting  Estimates—Ceded 
Reinsurance”  and  “Risk  Factors—Risks  Relating  to  Our 
Industry, Business and Operations—The failure of any of the 
loss  limitation  methods  we  employ  could  have  a  material 
adverse  effect  on  our  financial  condition  or  results  of 
operations.”

Claims  Management.  Claims  management  includes  the 
receipt  of  initial  loss  reports,  creation  of  claim  files, 
determination  of  whether  further  investigation  is  required, 
establishment  and  adjustment  of  case  reserves  and  payment 
of claims. Additionally, audits are conducted for both specific 
claims  and  overall  claims  procedures  at  the  offices  of 
selected ceding companies. Our reinsurance group makes use 
of outside consultants for claims work from time to time.

Our  mortgage  operations  include  mortgage  insurance  and 
reinsurance  in  the  U.S.  and  internationally,  as  well  as 
participation  in  GSE  credit  risk-sharing  transactions.  Our 
mortgage  group  includes  direct  mortgage  insurance  in  the 
U.S.  primarily  through  Arch  Mortgage  Insurance  Company, 
United  Guaranty  Residential  Insurance  Company,  and  Arch 
Mortgage  Guaranty  Company  (together,  “Arch  MI  U.S.”); 
mortgage reinsurance primarily through Arch Re Bermuda on

In  2014,  we  entered 
insurance 
marketplace,  underwriting  on  the  Arch  Mortgage  Insurance 
Company  platform.  Arch  Mortgage  Insurance  Company  is 
licensed  and  operates  in  all  50  states,  the  District  of 
Columbia and Puerto Rico. In December 2016, we completed 
the acquisition of UGC and its primary operating subsidiary, 
United  Guaranty  Residential  Insurance  Company,  which  is 
licensed  and  operates  in  all  50  states  and  the  District  of 
Columbia.  In  November  2023,  we  signed  an  agreement  to 
acquire  RMIC  Companies,  Inc.  and  its  subsidiaries  that 
together comprise the run-off mortgage insurance business of 
Old Republic International Corporation. The sale is expected 
to  close  in  the  first  half  of  2024,  subject  to  regulatory 
approvals and other closing conditions.

Arch  Mortgage  Insurance  Company  and  United  Guaranty 
Residential Insurance Company have each been approved as 
an eligible mortgage insurer by Fannie Mae and Freddie Mac,

(“eligible  mortgage  insurer”).  Arch  Mortgage  Guaranty 
Company offers direct mortgage insurance to U.S. mortgage 
lenders with respect to mortgages that lenders intend to retain 
in  portfolio  or  include  in  non-agency  securitizations.  Arch 
Mortgage  Guaranty  Company,  which  is  licensed  in  all  50 
states  and  the  District  of  Columbia,  insures  mortgages  that 
are not intended to be sold to the GSEs, and it is therefore not 
approved by either GSE as an eligible mortgage insurer.

In  2019,  Arch  LMI  was  authorized  by  APRA  to  write 
lenders’  mortgage  insurance.  In  August  2021,  we  acquired 
Arch Indemnity, which is also authorized by APRA to write 
insurance.  In  December  2022,  we 
lenders’  mortgage 
converted  Arch  LMI  to  a  services  company  for  our 
Australian  lenders  mortgage  insurance  operations  and  the 
company  relinquished  its  APRA  authorization.  Arch  LMI 
and Arch Indemnity are headquartered in Sydney, Australia. 
Following  the  conversion  of  Arch  LMI,  Arch  Indemnity  is 
the  primary  provider  of  direct  lenders’  mortgage  insurance 
and reinsurance to the Australian market. 

Strategy.  The  mortgage  insurance  market  operates  on  a 
distinct  underwriting  cycle,  with  demand  driven  mainly  by 
the  housing  market  and  general  economic  conditions.  As  a 
result, the creation of the mortgage group provides us with a 
more diverse revenue stream. Our mortgage group’s strategy 
is  to  capitalize  on  its  financial  capacity,  mortgage  insurance 
technology  platform,  operational  flexibility  and  experienced 
management  to  offer  mortgage  insurance,  reinsurance  and 
other risk-sharing products in the U.S. and around the world.

Our mortgage group’s operating principles and goals are to:

•

believes  that  the  key  to  this  approach  is  maintaining 
discipline across all phases of the applicable housing and 
mortgage lending cycles.

industry,  and  its  analytics  and  technology  to  provide 
innovative  products  and  superior  service.  The  mortgage 
group  believes  that  its  delivery  of  tailored  products  that 
meet the specific, evolving needs of its customers will be 
a key to the group’s success.

• Maintain  our  position  as  a  leading  provider  of  U.S. 
mortgage  insurance  business.  With  the  acquisition  of 
UGC in 2016, a leading provider of mortgage insurance 
products and services to national and regional banks and 
mortgage  originators,  we  became  a  leading  provider  of 
U.S. mortgage insurance.

•

Diversify  revenues  by  capitalizing  on  international 
opportunities. With the acquisition of Arch Indemnity in 
Australia  in  2021,  and  continued  growth  insuring  and 
reinsuring  European  banks,  we  believe  diversifying 
revenues on a global basis is a key operating principle.

Our mortgage group focuses on the following areas:

Direct  mortgage  insurance  in  the  United  States.  Under 
their  monoline  insurance  licenses,  each  of  Arch’s 
eligible  mortgage  insurers  may  only  offer  private

originated  by  mortgage  lenders  and  sold  to  the  GSEs. 
Each GSE’s Congressional charter generally prohibits it 
from purchasing a mortgage where the principal balance 
of the mortgage is in excess of 80% of the value of the 
property securing the mortgage unless the excess portion 
of  the  mortgage  is  protected  against  default  by  lender 
recourse,  participation  or  by  a  qualified  insurer.  As  a 
result,  such  “high  loan-to-value  mortgages”  purchased 
by  Fannie  Mae  or  Freddie  Mac  generally  are  insured 
with private mortgage insurance.

•

•

Mortgage insurance protects the insured lender, investor 
or GSE against loss in the event of a borrower’s default. 
If  a  borrower  defaults  on  mortgage  payments,  private 
mortgage insurance reduces, and may eliminate, losses to 
the  insured.  Private  mortgage  insurance  may  also 
facilitate  the  sale  of  mortgage  loans  in  the  secondary 
mortgage  market  because  of  the  credit  enhancement  it 
provides. Our primary U.S. mortgage insurance policies 
predominantly cover individual loans and are effective at 
the  time  the  loan  is  originated.  We  also  may  enter  into 
insurance  transactions  with  lenders  and  investors,  under 
which  we  insure  a  portfolio  of  loans  at  or  after 
origination. Although not currently a significant product, 
we  may  offer  mortgage  insurance  on  a  “pool”  basis  in 
the  future.  Under  pool  insurance,  the  mortgage  insurer 
provides  coverage  on  a  group  of  specified  loans, 
typically  for  100%  of  all  contractual  or  policy-defined 
losses on every loan in the portfolio, subject to an agreed 
aggregate loss limit. Pool insurance may be in a first loss 
position  with  respect  to  loans  that  do  not  have  primary 
mortgage  insurance  policies,  or  it  may  be  in  a  second 
loss position, covering losses in excess of those covered 
by the primary mortgage insurance policy.

other 
profitable 
underwriting  opportunities.  Since  2011,  Arch  Insurance 
(EU)  has  offered  mortgage  insurance  to  European 
mortgage  lenders  in  order  to  reduce  lenders’  credit  risk 
and  regulatory  capital  requirements  associated  with  the 
insured  mortgages.  In  certain  European  countries, 
lenders  purchase  mortgage

regulatory compliance with respect to high loan-to-value

insurance  on  both  a  “flow”  basis 
to  cover  new 
originations and through structured transactions to cover 
one  or  more  portfolios  of  previously  originated 
residential loans. Increasingly, Arch Insurance (EU) and 
Arch Re Bermuda are providing protection to European 
banks  on  structured  capital  relief 
transactions.  In 
Australia,  Arch  Indemnity  provides  lenders’  mortgage 
insurance on a flow basis to cover new originations and 
offers  coverage  through  structured  transactions  to  cover 
one  or  more  portfolios  of  previously  originated 
residential loans.

Other  credit  risk-sharing  products.  In  addition  to 
and 
providing 
reinsurance, we offer various credit risk-sharing products 
to government agencies and mortgage lenders. The GSEs 
have reduced their exposure to mortgage risk by shifting 
a portion of it to the private sector, creating opportunities 
for insurers to assume additional mortgage risk. In 2013, 
Arch  Re  Bermuda  became 
the  first  (re)insurance 
company  to  participate  in  Freddie  Mac’s  program  to 
transfer certain credit risk in its single-family portfolio to 
the private sector. Since that time, Arch Re Bermuda and 
its  affiliates  have  regularly  participated  in  both  Fannie 
Mae and Freddie Mac single family and multifamily risk 
sharing programs.

In 2019, we established Arch Credit Risk Services (Bermuda) 
Ltd.  (“Arch  CRS”).  Arch  CRS  is  licensed  by  the  Bermuda 
Monetary  Authority  (“BMA”)  as  an  insurance  agent  in 
Bermuda.  Arch  CRS  offers  mortgage  credit  assessment  and 
underwriting  advisory  services  with  respect  to  participation 
in GSE credit risk transfer transactions. 

Underwriting Philosophy. Our mortgage group believes in a 
disciplined,  analytical  approach  to  underwriting  mortgage 
risks  by  utilizing  proprietary  and  third  party  models, 
including  forecasting  delinquency  and  future  home  price 
movements  with  the  goal  of  ensuring  that  premiums  are 
adequate  for  the  risk  being  insured.  Experienced  actuaries 
and statistical modelers are engaged in analytics to inform the 
underwriting  process.  As  part  of  the  underwriting  process, 
our  mortgage  group  typically  assesses  a  variety  of  factors, 
including the:

•

•

•

•

•

•

ability and willingness of the mortgage borrower to pay 
its obligations under the mortgage loan being insured;

characteristics  of  the  mortgage  loan  being  insured  and 
the value of the collateral securing the mortgage loan;

financial strength, quality of operations and reputation of 
the lender originating the mortgage loan;

home  price  trends  and  expected  future  home  price 
movements which vary by geography;

projections of future loss frequency and severity; and

adequacy of premium rates.

Sales and Distribution. In the U.S., we employ a sales force 
to  directly  sell  mortgage  insurance  products  and  services  to 
our  customers,  which  include  mortgage  originators  such  as 
mortgage  bankers,  mortgage  brokers,  commercial  banks, 
savings institutions, credit unions and community banks. Our 
largest  single  mortgage  insurance  customer  in  the  U.S. 
(including  branches  and  affiliates)  accounted  for  7.3%  and 
7.1%  of  our  gross  premiums  written  for  the  years  ending 
December  31,  2023  and  2022,  respectively.  No  other 
customer  accounted  for  greater  than  2.9%  and  2.8%  of  the 
gross  premiums  written  for  the  years  ending  December  31, 
2023  and  2022,  respectively.  The  percentage  of  gross 
premiums  written  on  our  top  10  customers  was  24.6%  and 
23.6%  as  of  December  31,  2023  and  2022,  respectively.  In 
Europe,  Bermuda  and  Australia,  our  products  and  services 
are  distributed  on  a  direct  basis  and  through  brokers.  Each 
country  represents  a  unique  set  of  opportunities  and 
challenges  that  require  knowledge  of  market  conditions  and 
client needs to develop effective solutions.

Risk  Management.  Exposure  to  mortgage  risk  is  monitored 
globally  and  managed  through  underwriting  guidelines, 
pricing,  reinsurance,  utilization  of  proprietary  risk  models, 
concentration limits and limits on net probable loss resulting 
from  a  severe  economic  downturn  in  the  housing  market. 
Exposure to climate risk has also been incorporated into the 
risk  management  framework  of  our  mortgage  group  to 
monitor  and  manage  our  exposure  to  potential  (i)  losses 
related  to  the  direct  physical  impact  of  extreme  weather 
conditions  or  events  in  certain  transactions;  and/or  (ii) 
adverse  economic  or  housing  market  conditions  caused  by 
the physical impact of extreme weather conditions or events 
on a region or the financial impact of transitioning to a zero 
or  low  carbon  economy  on  a  region.  Generally,  mortgage 
insurance  policies  exclude  direct  physical  losses  resulting 
from physical damages, such as damaged caused by extreme 
weather  events,  though  we  do  have  some  exposure  to 
physical damage in certain GSE credit risk transfer (“CRT”) 
transactions. Additionally, we actively monitor developments 
in the housing market, financial regulation and public policy 
in  the  geographies  where  our  mortgage  group  operates  to 
facilitate  implementation  of  laws,  regulations  and  policies 
which  support  sustainable  environmental  behavior  and 
mitigate the effects of climate change. For a discussion of our 
risk  management  policies,  see  “Management’s  Discussion 
and  Analysis  of  Financial  Condition  and  Results  of 
Operations—Summary  of  Critical  Accounting  Estimates—
Ceded  Reinsurance”  and  “Risk  Factors—Risks  Relating  to 
Our  Industry,  Business  and  Operations—The  failure  of  any 
of  the  loss  limitation  methods  we  employ  could  have  a 
material adverse effect on our financial condition or results of 
operations.” 

Our mortgage group has ceded a portion of its premium on a 
quota share basis through certain reinsurance agreements and 
through  aggregate  excess  of  loss  reinsurance  agreements 
which  provide  reinsurance  coverage  for  delinquencies  on 
portfolios of in-force policies issued between certain periods. 
See  note  8,  “Reinsurance,”  to  our  consolidated  financial 
statements in Item 8 for further details.

Reinsurance arrangements do not relieve our mortgage group 
from  its  primary  obligations  to  insured  parties.  Reinsurance 
recoverables  are  recorded  as  assets,  predicated  on  the 
reinsurers’  ability  to  meet  their  obligations  under  the 
reinsurance agreements. If the reinsurers are unable to satisfy 
their  obligations  under 
the  agreements,  our  mortgage 
subsidiaries would be liable for such defaulted amounts. For 
our U.S. mortgage insurance business, in addition to utilizing 
reinsurance, we have developed a proprietary risk model that 
simulates the maximum loss resulting from severe economic 
events  impacting  the  housing  market.  See  “Management’s 
Discussion  and  Analysis  of  Financial  Condition  and  Results 
of  Operations—Catastrophic  Events  and  Severe  Economic 
Events.”

Claims  Management.  With  respect  to  our  direct  mortgage 
insurance business, the claims process generally begins with 
notification by the insured or servicer to us of a default on an 
insured loan. The insured is generally required to notify us of 
a default after the borrower misses two consecutive monthly 
payments.  Borrowers  default  for  a  variety  of  reasons, 
including  a  reduction  of  income,  unemployment,  divorce, 
illness,  inability  to  manage  credit,  rising  interest  rate  levels 
and  declining  home  prices.  Upon  notice  of  a  default,  in 
certain  cases  we  may  coordinate  with  loan  servicers  to 
facilitate  and  enhance  retention  workouts  on  insured  loans. 
Retention workouts include payment deferral or forbearance, 
loan  modifications  and  other  loan  repayment  options,  which 
may  enable  borrowers  to  cure  mortgage  defaults  and  retain 
ownership of their homes. If a retention workout is not viable 
for a borrower, our loss on a loan may be mitigated through a 
liquidation  workout  option,  including  a  pre-foreclosure  sale 
or a deed-in-lieu of foreclosure. 

In the U.S., our master policies generally provide that within 
60  days  of  the  perfection  of  a  primary  insurance  claim,  we 
have the option of: 

•

•

paying  the  insurance  coverage  percentage  specified  in 
the  certificate  of  insurance  multiplied  by  the  loss 
amount; 

in the event the property is sold pursuant to an approved 
prearranged  sale,  paying  the  lesser  of  (i)  100%  of  the 
loss amount less the proceeds of sale of the property, or 
(ii)  the  specified  coverage  percentage  multiplied  by  the 
loss amount; or

paying  100%  of  the  loss  amount  in  exchange  for  the 
insured’s conveyance to us of good and marketable title 
to the property, with us then selling the property for our 
own account. 

While  we  select  the  claim  settlement  option  that  best 
mitigates  the  amount  of  our  claim  payment,  in  the  U.S.  we 
generally pay the coverage percentage multiplied by the loss 
amount.

Other Operations

In  2014,  we  and  HPS  Investment  Partners,  LLC  (formerly 
Highbridge Principal Strategies, LLC) (“HPS”) sponsored the 
formation  of  Somers.  Arch  Re  Bermuda  invested  $100.0 
million  in  Somers  common  equity.  Somers’  strategy  is  to 
combine  a  diversified  reinsurance  and  insurance  business 
with  a  disciplined 
investment  strategy.  Somers’  own 
management  and  board  of  directors  are  responsible  for  its 
results  and  profitability.  Arch  Re  Bermuda  has  appointed 
three directors to serve on the seven person board of directors 
of Somers. In the 2020 fourth quarter, Arch Capital, Somers 
and Greysbridge, a wholly-owned subsidiary of Arch Capital, 
entered into a Merger Agreement pursuant to which, among 
other  things,  Arch  Capital  agreed  to  acquire  all  of  the 
common  shares  of  Somers  not  owned  by  Arch  for  a  cash 
purchase price of $35.00 per common share. Arch Capital has

financing  closed  on  July  1,  2021.  Effective  July  1,  2021, 
Somers is wholly owned by Greysbridge, and Greysbridge is 
owned  40%  by  Arch,  30%  by  certain  investment  funds 
managed  by  Kelso  and  30%  by  certain  investment  funds

In  2021,  the  Company  completed  the  share  purchase 
agreement  with  Natixis  to  purchase  29.5%  of  the  common

Coface,  and  fits  with  Arch’s  efforts  to  develop  uncorrelated 
sources of underwriting income. Our companies share a focus 

on  specialty  underwriting  where  knowledge  and  expertise 
create  value  for  our  clients,  and  trade  credit  contributes  to 
Arch’s  specialty-driven  business  model.  Arch  has  appointed 
four directors to serve on the ten person board of directors of

RESERVES

Reserves  for  losses  and  loss  adjustment  expenses  (“Loss 
Reserves”)  represent  estimates  of  what  the  insurer  or 
reinsurer ultimately expects to pay on claims at a given time, 
based  on  facts  and  circumstances  then  known,  and  it  is 
probable that the ultimate liability may exceed or be less than 
such  estimates.  Even  actuarially  sound  methods  can  lead  to 
subsequent  adjustments  to  reserves  that  are  both  significant 
and  irregular  due  to  the  nature  of  the  risks  written.  Loss 
Reserves are inherently subject to uncertainty. 

For  detail  on  our  Loss  Reserves  by  segment  and  potential 
variability  in  the  reserving  process,  see  the  Loss  Reserves

Talent  Acquisition,  Development,  Rewards  and  Retention. 
Our employees are integral to the company, and we maintain 
a sharp focus on improving the ways we attract, develop and 
retain  our  high-performing  talent.  Our  goal  is  to  cultivate  a 
workplace  culture  where  all  our  employees  can  thrive  by 
building  awareness  of  inclusive  practices  and  incorporating 
them  into  our  regular  course  of  business.  In  2023,  we 
launched a new talent acquisition model that modernizes our 
approach  to  the  talent  market  and  maximizes  our  ability  to 
find  and  hire  top  talent  across  multiple  talent  pools  and 
proactively  source  pipelines  of  key  talent.  In  addition,  the 
new model has streamlined this process across our Company 
by using a common platform that we can easily scale as we 
grow.

and 

We  provide  career  growth  opportunities 
through  a 
combination of on-the-job training and experience, exposure 
to top-notch colleagues who coach and mentor, and education 
and  training  programs  designed  to  accelerate  learning  and 
applying  new  skills  and  behaviors.  We  offer  competitive 
compensation 
comprehensive  benefits  packages, 
including  an  employee  share  purchase  plan,  parental  leave, 
contributions  to  retirement  savings  plans  and  programs  to 
support  employee  mental  and  physical  well-being.  We 
recognize  the  financial  burden  of  educational  loans  in  the 
United  States  and  have  supported  our  employees  with  a 
student  debt  assistance  program.  Since  the  inception  of  the 
program  in  2018,  Arch  has  contributed  approximately  $5 
million  to  this  program,  including  $0.9  million  in  2023.  We 
also  match  eligible  contributions  to  qualified  charitable 
organizations  and  employees  are  offered  two  paid  volunteer 
time-off  days  per  calendar  year  with  an  eligible  non-profit 
organization.  Our  Arch  Achieve  program  has  recognized 
over  500  employees  for  excellence  since  its  inception  in 
2009,  and  each  recipient  is  awarded  a  cash  bonus  to 
recognize their accomplishments.

In 2023, our senior leadership team met in person to discuss 
our  strategy  and  vision  for  the  future,  foster  continuous 
learning  and  a  growth  mindset  for  leaders  and  provide  a 
forum for global executives to network across the Company.

To  ease  the  impact  on  those  most  affected  by  inflation, 
effective  in  2023,  Arch  introduced  a  salary-based  premium 
structure for medical plans for U.S. based employees to help 
keep  health  care  costs  equitable  and  affordable.  More  than 
65%  of  employees  had  reductions  in  medical  premiums  for 
the same plan and coverage tier.

We  also  encourage  employees  to  continue  their  educational 
and professional development through tuition reimbursement

financial  security  of  companies  in  our  industry.  We  believe 
that the primary users of such ratings include commercial and 
investment  banks,  policyholders,  brokers,  ceding  companies

and  reinsurance  intermediaries  as  an  important  means  of 
assessing  the  financial  strength  and  quality  of  insurers  and 
reinsurers,  and  are  often  an  important  factor  in  the  decision 
by  an  insured  or  intermediary  of  whether  to  place  business 
with a particular insurance or reinsurance provider. 

The financial strength ratings of our operating insurance and 
reinsurance  subsidiaries  are  subject  to  periodic  review  as 
rating  agencies  evaluate  us  to  confirm  that  we  continue  to 
meet their criteria for ratings they have assigned to us. Such

ENTERPRISE RISK MANAGEMENT

General.  Enterprise  Risk  Management  (“ERM”)  is  a  key 
element in our philosophy, strategy and culture. We employ 
an  ERM  framework  that  includes  underwriting,  reserving, 
investment, credit, group and operational risks. Risk appetite 
and  exposure  limits  are  set  by  our  executive  management 
team,  reviewed  with  the  Board  and  its  committees  and 
routinely  discussed  with  business  unit  management.  These 
limits  are  articulated  in  our  risk  appetite  statement,  which 
details risk appetite, tolerances and limits for each major risk 
category,  and  are  integrated  into  our  operating  guidelines. 
Exposures are aggregated and monitored periodically by our 
corporate  risk  management  team.  The  reporting,  review  and 
approval  of  risk  management  information  is  integrated  into 
our annual planning process, capital modeling and allocation, 
and  reinsurance  purchasing  strategy.  Such  information  is 
reviewed  at 
reinsurance 
insurance  business 
underwriting meetings and board level committees.

Risk  Management  Process  and  Procedures.  The  following 
narrative  provides  an  overview  of  our  risk  management 
framework and our methodology for identifying, measuring, 
managing  and  reporting  on  the  key  risks  affecting  us.  It 
outlines  our  approach  to  risk  identification  and  assessment 
and  provides  an  overview  of  our  risk  appetite  and  tolerance 
for  each  of 
the  following  major  risks:  underwriting 
(insurance) risk including pricing, reserving and catastrophe; 
investment  risk  including  market  and  liquidity  risks;  group 
risk  including  strategic,  governance,  rating  agency  and 
capital market risk; credit risk; and operational risk including 
regulatory, 
risk)  and 
outsourcing  risks.  We  view  environmental,  social  and 
governance (“ESG”) related risks not as standalone risks but 
as  an  integral  part  of  our  enterprise-wide  risk  management 
strategy.  Consequently,  evaluations  of 
these  risks  are 
embedded throughout our risk management framework.

(reputational 

relations 

investor 

The  framework  includes  details  of  our  risk  philosophy  and 
policies  to  address  the  material  risks  confronting  us  and  the 
approach  and  procedures  to  control  and  or  mitigate  these 
risks.  The  actions  and  policies  implemented  to  meet  our 
business  management  and  regulatory  obligations  form  the 
core of this framework. We have adopted a holistic approach 
to risk management by analyzing risk from both a top-down 
and bottom-up perspective.

Risk Identification and Assessment. The Finance, Investment 
and  Risk  Committee  (“FIR  Committee”),  Audit  Committee 
and Underwriting Oversight Committee of the Board oversee 
the  top-down  and  bottom-up  review  of  our  risks.  Given  the 
nature and scale of our operations, these committees consider 
all aforementioned risks within the scope of the assessment. 
Arch  Capital’s  Chief  Risk  Officer  (“CRO”)  assists  these 
committees  in  the  identification  and  assessment  of  all  key 
risks. The CRO is responsible for maintaining Arch Capital’s 
risk  register  and  continually  reviewing  and  challenging  risk 
assessments,  including  the  impact  of  emerging  risks  and 
significant business developments. Any new high-level risks 
or changes in inherent or residual designations are brought to 
the Board’s or the relevant committee’s attention.

Risk  Monitoring  and  Control.  Arch  Capital’s 
risk 
management framework requires risk owners to monitor key 
risks  on  a  continuous  basis.  The  highest  residual  risks  are 
actively managed by the Board and relevant committees. The 
remaining risks are managed and monitored at a process level 
by  the  risk  owners  and/or  the  CRO.  Risk  owners  have 
ultimate  responsibility  for  the  day-to-day  management  of 
each designated risk, reporting to the CRO on the satisfactory 
management and control of the risk and timely escalation of 
significant  issues  that  may  arise  in  relation  to  that  risk.  The 
CRO is responsible for overseeing the monitoring of all risks 
across  the  business  and  for  communicating  to  the  relevant 
risk owners if she becomes aware of issues, or potential and 
actual breaches of risk appetite, relevant to the assigned risks. 
A  key  element  of  these  monitoring  activities  is  the  periodic 
evaluation  of  our  position  relative  to  risk  tolerances  and 
limits approved by the Board.

Risk  Reporting.  Quarterly,  the  CRO  compiles  the  results  of 
the  key  risk  review  process  into  a  report  to  the  Board  and 
relevant  committees  for  review  and  discussion  at  their  next 
meeting.  The  report  includes  an  overview  of  selected  key 
risks; a risk dashboard that depicts the status of risk limit and 
tolerance metrics; changes in the rating of high-level risks in 
the  Arch  Capital  risk  register;  and  summaries  of  our  largest 
exposures  and  reinsurance  recoverables.  If  necessary,  risk 
management matters reviewed at the committee meetings are 
presented  for  discussion  by  the  Board.  The  CRO  is 
responsible  for  immediately  escalating  any  significant  risk 
matters  to  executive  management,  the  respective  Board 
Committee  and/or  the  Board  for  approval  of  the  required 
remediation. As part of our corporate governance, the Board

with  members  of  our  management  team.  These  sessions  are 
intended  to  ensure  an  open  and  frank  dialogue  exists  about 
various forms of risk across the organization.

General

Integration.  We  believe 

that  an 
Implementation  and 
integrated  approach  to  developing,  measuring  and  reporting 
our  Own  Risk  and  Solvency  Assessment  (“ORSA”)  is  an 
important  part  of  the  risk  management  framework.  The 
ORSA process provides the link between Arch Capital’s risk 
profile,  its  board-approved  risk  appetite  including  approved 
risk tolerances and limits, its business strategy and its overall 
solvency  requirements.  The  ORSA  is  the  entirety  of  the 
processes  and  procedures  employed  to  identify,  assess, 
monitor, manage, and report the short and long-term risks we 
face  or  may  face  and  to  determine  the  capital  necessary  to 
ensure  that  our  overall  solvency  needs  are  met  at  all  times. 
The  ORSA  also  makes  the  link  between  actual  reported 
results and the capital assessment.

The ORSA is the basis for risk reporting to the Board and its 
committees  and  acts  as  a  mechanism  to  embed  the  risk 
framework  within  our  decision  making 
management 
processes  and  operations.  The  Board  has  delegated 
responsibility  for  supervision  and  oversight  of  the  ORSA  to 
the  FIR  Committee.  This  oversight  includes  regular  reviews 
of  the  ORSA  process  and  output.  An  ORSA  report  is 
produced at least annually, and the results of each assessment 
are reported to the Board. The Board actively participates in 
the  ORSA  process  by  steering  how  the  assessment  is 
performed and challenging its results. This assessment is also 
taken into account when formulating strategic decisions.

The ORSA process and reporting are also important parts of 
our  business  strategy,  tailored  specifically  to  fit  into  our 
organizational  structure  and  risk  management  system  with 
the  appropriate  techniques  in  place  to  assess  our  overall 
solvency  needs,  taking  into  consideration  the  nature,  scale 
and complexity of the risks inherent in the business.

Our  insurance  and  reinsurance  subsidiaries  are  subject  to

jurisdictions  in  which  they  operate.  We  are  subject  to 
extensive  regulation  under  applicable  statutes  in  these

Bermuda

General. Our main Bermuda insurance operating subsidiary, 
Arch Re Bermuda, is a Class 4 general business insurer and a 
Class C long-term insurer and is subject to the Insurance Act 
1978  of  Bermuda  and  related  regulations,  as  amended 
(“Insurance  Act”).  Among  other  matters,  the  Insurance  Act 
imposes  certain  solvency  and  liquidity  standards,  auditing 
and reporting requirements, the submission of certain period 
examinations of its financial conditions and grants the BMA 
powers  to  supervise,  investigate,  require  information  and 
demand  the  production  of  documents  and  intervene  in  the 
affairs  of  insurance  companies.  Significant  requirements 
include  the  appointment  of  an  independent  auditor,  the 
appointment of a loss reserve specialist, the appointment of a 
principal  representative  in  Bermuda,  the  filing  of  annual 
Statutory  Financial  Returns,  the  filing  of  annual  financial 
statements  in  accordance  with  U.S.  generally  accepted 
accounting  principles  (“GAAP”),  the  filing  of  an  annual 
capital  and  solvency  return,  compliance  with  minimum  and 
enhanced  capital  requirements,  compliance  with  certain 
restrictions  on  reductions  of  capital  and  the  payment  of 
dividends and distributions, compliance with group solvency 
and supervision rules, if applicable, and compliance with the 
Insurance Code of Conduct (relating to corporate governance, 
risk management and internal controls). 

Arch  Re  Bermuda  must  also  comply  with  a  minimum 
liquidity ratio and minimum solvency margin in respect of its 
general  business.  The  minimum  liquidity  ratio  requires  that 
the value of relevant assets must not be less than 75% of the 
amount  of  relevant  liabilities.  The  minimum  solvency 
margin, which varies depending on the class of the insurer, is 
determined  as  a  percentage  of  either  net  reserves  for  losses 
and  loss  adjustment  expenses  (“LAE”)  or  premiums  or 
pursuant to a risk-based capital measure. Arch Re Bermuda is 
also  subject  to  an  enhanced  capital  requirement  (“ECR”) 
which  is  established  by  reference  to  either  the  Bermuda 
Solvency  Capital  Requirement  model  (“BSCR”)  or  an 
approved internal capital model. The BSCR model is a risk-
based capital model which provides a method for determining 
an  insurer’s  capital  requirements  (statutory  capital  and

surplus)  by  taking  into  account  the  risk  characteristics  of 
different  aspects  of  the  insurer’s  business.  The  BMA  has 
established  a  target  capital  level  for  each  Class  4  insurer 
equal  to  120%  of  its  ECR.  While  a  Class  4  insurer  is  not 
currently 
its  available  statutory 
economic  capital  and  surplus  at  this  level,  the  target  capital 
level serves as an early warning tool for the BMA, and failure 
to maintain statutory capital at least equal to the target capital 
level will likely result in increased regulatory oversight. As a 
Class  C  insurer,  Arch  Re  Bermuda  is  also  required  to 
maintain  available  statutory  economic  capital  and  surplus  in 
respect  of  its  long-term  business  at  a  level  equal  to  or  in 
excess  of  its  long-term  enhanced  capital  requirement  that  is 
established by reference to either the Class C BSCR model or 
an approved internal capital model.

Arch Re Bermuda is prohibited from declaring or paying any 
dividends  during  any  financial  year  if  it  is  in  breach  of  its 
general  business  or  long-term  business  enhanced  capital 
requirements,  minimum  solvency  margins  or  its  general 
business  minimum  liquidity  ratio  or  if  the  declaration  or 
payment  of  such  dividends  would  cause  such  a  breach.  If  it 
has  failed  to  meet  its  minimum  solvency  margins  or 
minimum liquidity ratio on the last day of any financial year, 
Arch Re Bermuda will be prohibited, without the approval of 
the BMA, from declaring or paying any dividends during the 
next  financial  year.  In  addition,  Arch  Re  Bermuda  is 
prohibited  from  declaring  or  paying  in  any  financial  year 
dividends of more than 25% of its total statutory capital and 
surplus  (as  shown  on  its  previous  financial  year’s  statutory 
balance  sheet)  unless  it  files  (at  least  seven  days  before 
payment  of  such  dividends)  with  the  BMA  an  affidavit 
stating  that  it  will  continue  to  meet  the  required  margins. 
Without  the  approval  of  the  BMA,  Arch  Re  Bermuda  is 
prohibited  from  reducing  by  15%  or  more  its  total  statutory 
capital  as  set  out  in  its  previous  year’s  financial  statements 
and  any  application  for  such  approval  must  include  an 
affidavit  stating  that  it  will  continue  to  meet  the  required 
margins. Where such an affidavit is filed, it shall be available 
for  public  inspection  at  the  offices  of  the  BMA.  Under  the 
Bermuda  Companies  Act  of  1981,  as  amended  (the 
“Companies  Act”),  Arch  Re  Bermuda  may  declare  or  pay  a 
dividend out of distributable reserves only if it has reasonable 
grounds  for  believing  that  it  is,  or  would  after  the  payment 
be,  able  to  pay  its  liabilities  as  they  become  due  and  if  the 
realizable  value  of  its  assets  would  thereby  not  be  less  than 
its liabilities. 

Policyholder  Priority.  The  Insurance  Amendment  (No.  2) 
Act 2018 amended the Insurance Act to provide for the prior 
payment  of  policyholders’ 
liabilities  ahead  of  general 
unsecured creditors in the event of the liquidation or winding 
up  of  an  insurer.  The  amendments  provide  inter  alia  that, 
subject  to  certain  statutorily  preferred  debts,  the  insurance 
debts  of  an  insurer  must  be  paid  in  priority  to  all  other 
unsecured debts of the insurer. Insurance debt is defined as a 

debt to which an insurer is or may become liable pursuant to 
an  insurance  contract  excluding  debts  owed  to  an  insurer 
under  an  insurance  contract  where  the  insurer  is  the  person 
insured.

Group Supervision. The BMA acts as group supervisor of our 
group of insurance and reinsurance companies (“Group”) and 
has  designated  Arch  Re  Bermuda  as  the  designated  insurer 
(“Designated  Insurer”).  As  our  Group  supervisor,  the  BMA 
performs  a  number  of  functions  including:  (i)  coordinating 
the  gathering  and  dissemination  of  relevant  or  essential 
information  for  going  concerns  and  emergency  situations, 
including  the  dissemination  of  information  which  is  of 
importance  for  the  supervisory  task  of  other  competent 
authorities;  (ii)  carrying  out  supervisory  reviews  and 
assessments  of  our  Group;  (iii)  carrying  out  assessments  of 
our  Group's  compliance  with  the  rules  on  solvency,  risk 
concentration, intra-group transactions and good governance 
procedures;  (iv)  planning  and  coordinating  through  regular 
meetings  held  at  least  annually  (or  by  other  appropriate 
means)  with  other  competent  authorities,  supervisory 
activities  in  respect  of  our  Group;  both  as  a  going  concern 
(v)  coordinating  any 
and 
enforcement  action  that  may  need  to  be  taken  against  our 
Group  or  any  Group  members;  and  (vi)  planning  and 
coordinating  meetings  of  colleges  of  supervisors  in  order  to 
facilitate  the  carrying  out  of  these  functions.  As  Designated 
Insurer, Arch Re Bermuda is required to facilitate compliance 
by  our  Group  with  the  group  insurance  solvency  and 
supervision rules.

in  emergency 

situations 

On  an  annual  basis,  the  Group  is  required  to  file  Group 
statutory  financial  statements,  a  Group  statutory  financial 
return,  a  Group  capital  and  solvency  return,  audited  Group 
financial  statements,  a  Group  Solvency  Self-Assessment 
(“GSSA”),  and  a  financial  condition  report  with  the  BMA. 
The  GSSA  is  designed  to  document  our  perspective  on  the 
capital resources necessary to achieve our business strategies 
and remain solvent, and to provide the BMA with insights on 
and 
risk  management,  governance  procedures 
our 
documentation  related  to  this  process.  In  addition,  the 
Designated  Insurer  is  required  to  file  quarterly  group 
financial  returns  with  the  BMA.  The  Group  is  also  required 
to  maintain  available  Group  statutory  economic  capital  and 
surplus  in  an  amount  that  is  at  least  equal  to  the  group 
enhanced  capital  requirement  (“Group  ECR”)  and  the  BMA 
has established a group target capital level equal to 120% of 
the Group ECR.

Fit and Proper Controllers. The BMA maintains supervision 
over  the  controllers  of  all  Bermuda  registered  insurers, 
brokers,  agents  and  insurance  marketplace  providers.  For  so 
long as the shares of Arch Capital are listed on the Nasdaq or 
another recognized stock exchange, any person who, directly 
or indirectly, becomes a holder of at least 10%, 20%, 33% or 
50% of our common shares must notify the BMA in writing

within  45  days  of  becoming  such  a  holder  (or  ceasing  to  be 
such  a  holder).  The  BMA  may  object  to  such  a  person  and 
require  the  holder  to  reduce  its  holding  of  common  shares 
and direct, among other things, that voting rights attaching to 
the common shares shall not be exercisable.

Economic  Substance  Act.  In  December  2018,  Bermuda 
enacted  the  Economic  Substance  Act  2018  (as  amended)  of 
Bermuda and its related regulations (together, the “ES Act”). 
The ES Act came into force on January 1, 2019, and provides 
that a registered entity other than an entity which is resident 
for  tax  purposes  in  certain  jurisdictions  outside  Bermuda 
(“non-resident  entity”)  that  carries  on  as  a  business  any  one 
or more of the “relevant activities” referred to in the ES Act 
must comply with economic substance requirements. The list 
of “relevant activities” includes carrying on any one or more 
of 
fund 
management,  financing, 
leasing,  headquarters,  shipping, 
distribution  and  service  center,  intellectual  property  and 
holding entities. Under the ES Act, if a company is engaged 
in one or more “relevant activities”, it is required to maintain 
a  substantial  economic  presence  in  Bermuda  and  to  comply 
with the economic substance requirements set forth in the ES 
Act. A company will comply with those economic substance 
requirements  if  it:  (a)  is  managed  and  directed  in  Bermuda; 
(b) undertakes “core income generating activities” (as may be 
prescribed  under  the  ES  Act)  in  Bermuda  in  respect  of  the 
relevant activity; (c) maintains adequate physical presence in 
Bermuda;  (d)  has  adequate  full  time  employees  in  Bermuda 
with suitable qualifications; and (e) incurs adequate operating 
expenditure  in  Bermuda  in  relation  to  the  relevant  activity 
undertaken by it.

the  existing  provisions  of  (a) 

Companies  that  are  licensed  under  the  Insurance  Act  and 
thereby carry on insurance as a relevant activity are generally 
considered to operate in Bermuda with adequate substance if 
they  comply  with 
the 
Companies Act relating to corporate governance; and (b) the 
Insurance Act, that are applicable to the economic substance 
requirements,  and  the  Registrar  will  have  regard  to  such 
companies’ compliance in his assessment of compliance with 
the  economic  substance  requirements.  That  being  said,  such 
companies  are  still  required 
to  complete  and  file  a 
Declaration Form, with the Bermuda Registrar of Companies 
and  the  Registrar  will  also  have  regard  to  the  information 
provided in that Declaration Form in making his assessment 
of compliance with the ES Act.

Insurance Sector Operational Cyber Risk Management Code 
of  Conduct  (“Cyber  Risk  Management  Code  of  Conduct”). 
The  BMA  recognized  that  cyber  incidents  can  cause 
significant financial losses and/or reputational impacts across 
the  insurance  industry  and  implemented  the  Cyber  Risk 
Management Code of Conduct in October 2020. All Bermuda 
insurers,  insurance  managers  and  intermediaries  registered 
under  the  Insurance  Act  are  required  to  comply  with  the 

BMA’s  Cyber  Risk  Management  Code  of  Conduct,  which 
established duties, requirements and standards to be complied 
by  each  registrant  in  relation  to  operational  cyber  risk 
management.  This  requires  Arch  Re  Bermuda  to  develop  a 
cyber  risk  policy,  which  is  to  be  delivered  pursuant  to  an 
operational  cyber  risk  management  program  and  appoint  an 
appropriately  qualified  member  of  staff  or  outsourced 
resource  to  the  role  of  Chief  Information  Security  Officer. 
The  role  of  the  Chief  Information  Security  Officer  is  to 
deliver the operational cyber risk management program.

It is expected that the cyber risk policy will be approved by 
the  Arch  Re  Bermuda  board  of  directors  at  least  annually. 
The  BMA  will  assess  Arch  Re  Bermuda’s  compliance  with 
in  a 
the  Cyber  Risk  Management  Code  of  Conduct 
proportionate  manner  relative  to  the  nature,  scale  and 
complexity  of  its  business.  Failure  to  comply  with  the 
requirements  of  the  Cyber  Risk  Management  Code  of 
Conduct  will  be  taken  into  account  by  the  BMA  in 
determining  whether  Arch  Re  Bermuda  is  conducting  its 
business in a sound and prudent manner as prescribed by the 
Insurance  Act  and  may  result  in  the  BMA  exercising  its 
powers of intervention and investigation.

Notification  of  Cyber  Reporting  Events.  Every  Bermuda 
insurer is required to notify the BMA forthwith on it coming 
to  the  knowledge  of  the  insurer,  or  where  the  insurer  has 
reason to believe that a Cyber Reporting Event has occurred. 
Within  fourteen  (14)  days  of  such  notification,  the  insurer 
must also furnish the BMA with a written report setting out 
all  of  the  particulars  of  the  Cyber  Reporting  Event  that  are 
available to it. A Cyber Reporting Event includes any act that 
results in the unauthorized access to, disruption, or misuse of 
electronic  systems  or  information  stored  on  such  systems  of 
an insurer, including breach of security leading to the loss or 
unlawful destruction or unauthorized disclosure of or access 
to such systems or information where there is a likelihood of 
an  adverse  impact  to  policyholders,  clients  or  the  insurer’s 
insurance  business,  or  an  event  that  has  occurred  for  which 
notice  is  required  to  be  provided  to  a  regulatory  body  or 
government agency.

Personal  Information  Protection  Act  2016.  Bermuda’s 
principal  data  protection  and  privacy  legislation  is  the 
Personal  Information  Protection  Act  2016  (“PIPA”).  At 
present,  the  majority  of  the  operative  provisions  of  PIPA, 
which  include  detailed  requirements  around  conditions  for 
use  and  consent  to  use  of  personal  information,  specific 
obligations  on  organizations  that  use  personal  information, 
overseas  data  transfer  assessment  obligations  and  access, 
rectification and erasure rights for individuals, are not yet in 
force  in  Bermuda.  In  June  2023,  the  Bermuda  Government 
and  the  Office  of  the  Privacy  Commissioner  for  Bermuda 
announced  that  the  remaining  operative  provisions  of  PIPA 
will become fully implemented on January 1, 2025.

provisions of PIPA.

U.S. based subsidiaries are required to file detailed quarterly 
and  audited  annual  statutory  financial  statements  with  state 
insurance  regulators.  In  addition,  regulatory  authorities 
conduct  periodic  financial,  claims  and  market  conduct 
examinations.  Certain  insurance  regulatory  requirements  are 
highlighted  below.  In  addition  to  regulation  applicable 
generally  to  U.S.  insurance  and  reinsurance  companies,  our 
U.S.  mortgage  insurance  operations  are  affected  by  federal 
and  state  regulation  relating  to  mortgage  insurers,  mortgage 
lenders, and the origination, purchase and sale of residential 
mortgages.  Arch  Insurance  (U.K.)  is  also  subject  to  certain 
governmental  regulation  and  supervision  in  the  states  where 
it writes excess and surplus lines insurance.

Corporate  Income  Tax  Act  2023  (the  “Bermuda  CIT  Act”). 
On December 27, 2023, Bermuda enacted the Bermuda CIT 
Act.  Entities  subject  to  tax  under  the  Bermuda  CIT  Act  are 
the Bermuda constituent entities of multi-national groups. A 
multi-national  group  is  defined  under  the  Bermuda  CIT  Act 
as  a  group  with  entities  in  more  than  one  jurisdiction  with 
consolidated revenues of at least €750 million for two of the 
four previous fiscal years. If Bermuda constituent entities of a 
multi-national  group  are  subject  to  tax  under  the  Bermuda 
CIT  Act,  such  tax  is  charged  at  a  rate  of  15%  of  the  net 
income  of  such  constituent  entities  (as  determined  in 
accordance  with  the  Bermuda  CIT  Act,  including  after 
adjusting for any relevant foreign tax credits applicable to the 
Bermuda  constituent  entities).  Although  the  commencement 
date  of  the  Bermuda  CIT  Act  is  January  1,  2024,  no  tax  is 
chargeable  under  the  Bermuda  CIT  Act  until  tax  years 
starting  on  or  after  January  1,  2025.  All  Arch  Bermuda 
operations  are  subject  to  the  requirements  of  the  Bermuda 
CIT Act.

United States

General. Our U.S. based insurance operating subsidiaries are 
subject to extensive governmental regulation and supervision 
by  the  states  and  jurisdictions  in  which  they  are  domiciled, 
licensed and/or approved to conduct business. The insurance 
laws  and  regulations  of  the  state  of  domicile  have  the  most 
significant  impact  on  operations.  We  currently  have  U.S. 
insurance  and/or  reinsurance  subsidiaries  domiciled 
in 
Delaware, North Carolina, Missouri, Wisconsin, Kansas and 
the  District  of  Columbia  and  we  may  acquire  insurers 
domiciled  in  other  states  in  the  future.  State  insurance

Holding  Company  Regulation.  All  states  have  enacted 
legislation that regulates insurance holding company systems. 
These  regulations  generally  provide  that  each  insurance 
company  in  the  system  is  required  to  register  with  the 
insurance  department  of  its  state  of  domicile  and  furnish 
information  concerning  the  operations  of  companies  within 
the holding company system which may materially affect the 
operations, management or financial condition of the insurers 
within the system. Notice to the state insurance departments 
is  required  prior  to  the  consummation  of  certain  material 
transactions between an insurer and any entity in its holding 
company  system  and  certain  transactions  may  not  be 
consummated  without  the  applicable  insurance  department’s 
prior approval or non-disapproval after receiving notice. The 
holding company acts also prohibit any person from directly 
or  indirectly  acquiring  control  of  a  U.S.  insurance  or 
that  person  has  filed  an 
reinsurance  company  unless

considered  an  acquisition  of  control  of  the  insurance 
company, although such presumption may be rebutted.

an  annual  enterprise  risk  report  by  the  ultimate  controlling 
person  identifying  the  material  risks  within  the  insurance

Credit for Reinsurance. Arch Re U.S. is subject to insurance 
regulation and supervision that is similar to the regulation of 
licensed  primary  insurers.  However,  except  for  certain 
mandated  provisions  that  must  be  included  in  order  for  a 
ceding  company  to  obtain  credit  for  reinsurance  ceded,  the 
terms and conditions of reinsurance agreements generally are 
not subject to regulation by any governmental authority.

insurer  ordinarily  will  enter 

A  U.S.  primary 
into  a 
reinsurance agreement only if it is able to obtain credit for the 
reinsurance  ceded  on  its  U.S.  statutory-basis  financial 
statements.  As  a  result  of  the  requirements  relating  to  the 
provision  of  credit  for  reinsurance,  Arch  Re  U.S.,  Arch  Re 
Bermuda  and  AGRL  are  indirectly  subject  to  certain 
regulatory  requirements  imposed  by  U.S.  jurisdictions  in 
which ceding companies are domiciled. In general, credit for 
reinsurance  is  allowed  if  the  reinsurer  is  licensed  or 
“accredited”  in  the  state  in  which  the  primary  insurer  is 
domiciled; or if none of the above applies, to the extent that 
the reinsurance obligations of the reinsurer are collateralized 
appropriately,  typically  through  the  posting  of  a  letter  of 
credit for the benefit of the primary insurer or the deposit of 
assets  into  a  trust  fund  established  for  the  benefit  of  the 
primary insurer. 

U.S. primary insurers also may receive credit for reinsurance 
ceded  to  unauthorized  reinsurers  without  collateral  or  with 
less than 100% collateral under revisions to the NAIC Credit 
for  Reinsurance  Model  Law  (#785)  and  the  Credit  for 
Reinsurance  Model  Regulation  (#786)  (collectively,  the 
“NAIC  Model  Law  and  Regulation”).  All  U.S.  states,  the 
District of Columbia and Puerto Rico have adopted revisions 
to the NAIC Model Law and Regulation that allow full credit 
to  U.S.  ceding  insurers  for  reinsurance  ceded  to  reinsurers 
that have been approved as “certified reinsurers” based upon 
less  than  100%  collateralization.  As  of  January  23,  2024, 

Arch  Re  Bermuda  is  approved  as  a  “certified  reinsurer”  for 
the 2024 calendar year in 44 states with applications pending 
in  8  additional  states  and  territories.  In  addition,  2019 
amendments  to  the  NAIC  Model  Law  and  Regulation 
eliminate  reinsurance  collateral  requirements  for  reinsurers 
that  (1)  have  their  head  office  or  are  domiciled  in  EU 
Member States, the U.K., NAIC accredited U.S. jurisdictions 
and  other  jurisdictions  deemed  “reciprocal  jurisdictions”  by 
the  NAIC  (although  individual  states  may  approve  or  reject 
the  designation  of  such  other  jurisdictions  as  a  “reciprocal 
jurisdiction”),  and  (2)  have  been  approved  as  a  “reciprocal 
jurisdiction reinsurer.” The NAIC list of approved reciprocal 
jurisdictions  includes  Bermuda,  Japan  and  Switzerland.  All 
U.S.  states,  the  District  of  Columbia  and  Puerto  Rico  have 
adopted the 2019 amendments to the NAIC Model Law and 
Regulation.  As  of  January  23,  2024,  Arch  Re  Bermuda  is 
approved as a “reciprocal jurisdiction reinsurer” for the 2024 
calendar  year  in  44  states  with  applications  pending  in  8 
additional  states  and  territories.  In  addition,  AGRL  received 
approval as a “reciprocal jurisdiction reinsurer” from its lead 
state  of  Missouri  in  November  2023,  which  is  effective  for 
the 2023 calendar year. AGRL intends to seek renewal of its 
“reciprocal  jurisdiction  reinsurer”  status  from  Missouri  in 
2024  and  will  potentially  seek  approval  from  additional 
states.

Risk  Management  and  ORSA.  The  NAIC  Risk  Management 
and  Own  Risk  Solvency  Assessment  Model  Act  (“ORSA 
Model  Act”)  provides  that  domestic  insurers,  or  their 
insurance group, must regularly conduct an ORSA consistent 
with  a  process  comparable  to  the  ORSA  Guidance  Manual 
process.  The  ORSA  Model  Act  also  provides  that,  no  more 
than  once  a  year,  an  insurer’s  domiciliary  regulator  may 
request that an insurer submit an ORSA summary report, or 
any  combination  of  reports 
the 
information  described  in  the  ORSA  Guidance  Manual,  with 
respect to the insurer and/or the insurance group of which it 
is  a  member.  States  may  impose  additional  internal  review 
and  regulatory  filing  requirements  on  licensed  insurers  and 
their  parent  companies.  All  states  have  enacted  the  ORSA

In  September  2022,  the  Federal  Insurance  Office  (“FIO”) 
within the Department of Treasury requested public comment 
on potential federal insurance responses to catastrophic cyber 
incidents  affecting  critical  infrastructure.  In  July  2023,  the 
Biden  Administration  published  a  National  Cybersecurity 
Strategy  Implementation  Plan  that  includes  as  a  strategic 
objective  the  exploration  of  a  federal  cyber  insurance 
backstop  and  identified  FIO  as  the  responsible  agency  for 
assessing  the  need  for  and  possible  structures  of  a  federal 
insurance  response.  In  November  2023,  the  FIO  announced 
initiatives  to  further  study  the  development  of  a  federal 
insurance backstop for catastrophic cyber events.

The NAIC adopted an Insurance Data Security Model Law in 
2017  that  requires  insurers,  insurance  producers  and  other 
entities required to be licensed under state insurance laws to 
comply with certain requirements under state insurance laws, 
such  as  developing  and  maintaining  a  written  information 
security program, conducting risk assessments overseeing the 
data  security  practices  of  third  party  service  providers  and 
meeting  expanded  breach  notification  requirements.  This 
model  law  has  been  adopted  in  states  in  which  our  U.S. 
subsidiaries are licensed and operate. In addition, certain state 
insurance  regulators  are  developing  or  have  developed 
regulations that may impose regulatory requirements relating 
to  cybersecurity  on  insurance  and  reinsurance  companies 
(potentially  including  insurance  and  reinsurance  companies 
that are not domiciled, but are licensed, in the relevant state). 
Many  regulators,  including  the  Federal  Trade  Commission 
(“FTC”),  the  New  York  Department  of  Financial  Services 
(“NYDFS”),  and  the  U.S.  Department  of  the  Treasury’s 
Office of Foreign Assets Control (“OFAC”), have issued new

Privacy  legislation  and  regulation  has  also  become  an  issue 
of increasing focus in many states. The California Consumer 
Privacy  Act  of  2018  (“CCPA”),  which  went  into  effect 
January 1, 2020 grants California consumers certain rights to, 
among  other  things,  access  and  delete  data  about  them 
subject  to  certain  exceptions,  as  well  as  a  private  right  of 
action  related  to  cybersecurity  breaches  with  statutory 
penalties. Additionally, the California Privacy Rights Act of

2023,  applies  to  some  of  our  data  collecting  and  processing 
activities,  and  it  provides  for  additional  consumer  privacy 
rights, and additional regulatory obligations over certain data. 
It  also  created  a  new  privacy  focused  California  regulatory 
agency  with  enforcement  authority,  the  California  Privacy

and,  as  delayed  by  a  state  court  decision,  are  expected  to 
become  enforceable  in  February  2024.  Rulemaking  is  also 
underway  on  regulations  mandated  by  the  CPRA  governing 
cybersecurity  audits,  risk  assessments,  and  automated 
decision-making,  but  additional  regulations  have  yet  to  be 
proposed.  The  CPPA  draft  rules  govern  consumer  notice, 
access, and opt-out rights with respect to automated decision-
making. Under the draft rules, businesses would also have to 
make  significant  disclosures  about  their  implementation  of 
automated  decision-making.  At  the  CPPA  December  board 
meeting,  the  board  requested  the  CPPA  staff  to  further 
evaluate  the  draft  regulations,  particularly  its  impact  within 
the workplace and in the employment context.

A range of new cybersecurity and privacy laws are also under 
consideration  in  other  states,  as  well  as  by  the  federal 
government. Several states, including Colorado, Connecticut, 
Utah, and Virginia adopted new comprehensive data privacy 
legislation  that  went  into  effect  in  2023.  Additional  states, 
including  Delaware,  Florida,  Iowa,  Montana,  New  Jersey, 
Oregon,  Tennessee,  and  Texas,  adopted  new  data  privacy 
legislation  that  will  go  into  effect  over  the  next  two  years 
(with a new Indiana data privacy law to take effect in 2026). 
While  these  state  laws  provide  consumer  privacy  rights  and 
protections like those in the CCPA and CPRA, they exempt 
entities  subject  to  the  Gramm-Leach-Bliley  Act  from  their 
requirements.

Artificial  Intelligence.  The  increased  use  of  automated 
processes  by 
including  algorithms,  artificial 
intelligence (generative and predictive) (“AI”) and predictive 
models that make use of large datasets and data analytics, has 
led  to  additional  regulatory  attention  to  insurer  practices 
including in relation to risk selection, pricing and claims, as 
well  as  governance  and  oversight  of  AI  and  predictive 
models.

technologies  used 

In  late  2023,  the  NAIC  adopted  a  model  bulletin  entitled 
“Use of Artificial Intelligence Systems by Insurers” that sets 
forth state insurance regulators’ expectations on how insurers 
the  use  of  advanced  analytical  and 
should  govern 
computational 
to  make  or  support 
decisions  impacting  consumers.  Such  expectations  include 
implementation of a written program for the responsible use 
of  AI  systems  that  make  or  support  decisions  related  to 
regulated  insurance  practices,  which  program  should  be 
designed  to  mitigate  certain  risks.  As  of  February  1,  2024, 
only one state has adopted the bulletin, but we expect it to be

and operate.

In  addition,  state  agencies,  departments  and  insurance 
regulators, including the California Department of Insurance, 
California Privacy Protection Agency, Connecticut Insurance 
Department,  New  York  Department  of  Consumer  and  Work 
Protection  and  NYDFS,  have  adopted,  proposed  or  released 
for comment laws, regulations and guidance that may impose 
regulatory  requirements  relating  to  the  use  of  AI  and 
automated  decision-making  on  insurance  and  reinsurance 
companies. Such requirements include (or may include) risk 
management processes and controls, governance frameworks, 
vendor  oversight  and  outcomes  testing  that  may  hinder  or 
delay  the  implementation  of  new  technologies  available  to 
other businesses.

In addition to insurance specific AI regulation there are many 
general  AI  proposals  and  frameworks.  For  example, 
President  Biden’s  Executive  Order  14110  on  Safe,  Secure, 
and  Trustworthy  Development  and  Use  of  Artificial 
Intelligence, 
issued  on  October  30,  2023  establishes 
extensive new standards for AI safety and security. 

Globally,  many  new  AI  laws  are  being  proposed,  the  most 
significant  of  which  may  be  in  the  EU.  See  “Regulation—
Europe” for further details on our insurance operations.

Risk-Based  Capital  Requirements.  Licensed  U.S.  property 
and casualty insurance and reinsurance companies are subject 
to risk-based capital requirements that are designed to assess 
capital  adequacy  and  to  raise  the  level  of  protection  that 
statutory  surplus  provides  for  policyholder  obligations.  The 
risk-based capital model for property and casualty insurance 
companies measures three major areas of risk facing property 
and  casualty  insurers:  underwriting,  which  encompasses  the 
risk  of  adverse  loss  developments  and  inadequate  pricing; 
declines in asset values arising from credit risk; and declines 
in asset values arising from investment risks. An insurer will 
be subject to varying degrees of regulatory action depending 
on how its statutory surplus compares to its risk-based capital 
calculation.  Under  the  approved  formula,  an  insurer’s  total 
adjusted  capital  is  compared  to  its  authorized  control  level 
risk-based capital. If this ratio is above a minimum threshold, 
no  company  or  regulatory  action  is  necessary.  Below  this 
threshold are four distinct action levels at which an insurer’s 
domiciliary  state  regulator  can  intervene  with  increasing 
degrees of authority over an insurer as the ratio of surplus to 
requirement  decreases.  The  mildest 
risk-based  capital 
regulatory  action  requires  an  insurer  to  submit  a  plan  for 
corrective  action;  the  most  severe  requires  an  insurer  to  be 
rehabilitated or liquidated. 

Our  mortgage  insurance  operations  are  not  currently  subject 
to state risk-based capital requirements, but rather are subject 
to  state  risk  to  capital  or  minimum  policyholder  position 

requirements.  The  NAIC  adopted  a  revised  Mortgage 
Guaranty Insurance Model Act in 2023. It is uncertain when 
or if it will be adopted in any jurisdiction.

Guaranty  Funds.  Most  states  require  all  admitted  insurance 
companies  to  participate  in  their  respective  guaranty  funds 
which cover certain claims against insolvent insurers. Solvent 
insurers  licensed  in  these  states  are  required  to  cover  the 
losses  paid  on  behalf  of  insolvent  insurers  by  the  guaranty 
funds and are generally subject to annual assessments in the 
states by the guaranty funds to cover these losses. Mortgage 
guaranty  insurance,  among  other  lines  of  business,  is 
typically exempt from participation in guaranty funds.

Climate  Change  and  Financial  Risks.  U.S.  state  insurance

company governance, reporting and disclosure relating to the 
potential risks presented by climate change and one or more 
states  may  adopt  climate-change-related  requirements  that 
impact  our  insurance  and  reinsurance  companies.  In  2020, 
NYDFS  issued  a  circular  letter  stating  that  NYDFS  expects

strategies, including the designation of a board committee or 
member  and  senior  management  function  to  be  accountable 
for  the  company’s  assessment  and  management  of  the 
financial risks from climate change. In 2021, NYDFS issued 
additional  guidance  for  New  York  Domestic  Insurers  on 
Managing  the  Financial  Risks  from  Climate  Change  that 
reiterates many of the principles outlined in the 2020 circular 
letter.  New  York  and  other  states  also  require  licensed 
insurers  with  countrywide  premium  written  of  at  least  $100 
million  to  annually  provide  disclosure  of  their  assessment 
and management of climate related risks. 

In  November  2023,  the  FIO  published  a  request  to  proceed 
with a climate-related data call that would collect five years 
of  homeowners’  insurance  underwriting  data  to  evaluate  the 
relationship between underwriting trends and weather-related 
events.  Separately,  in  December  2023,  the  NAIC  outlined 
plans  for  its  own  substantially  similar  climate-related  data. 
The  FIO  and  NAIC  climate-related  information  gathering 
could culminate in recommendations for new federal or state 
legislation.

Other  Federal  Regulation.  Although  state  regulation  is  the 
dominant  form  of  regulation  for  insurance  and  reinsurance 
business,  a  number  of  federal  laws  affect  and  apply  to  the 
insurance industry. The Dodd-Frank Wall Street Reform and 
Consumer  Protection  Act  of  2010  (“Dodd-Frank”)  created 
the  FIO,  which  is  not  a  federal  regulator  or  supervisor  of 
insurance,  but  monitors  the  insurance  industry  for  systemic 
risk,  administers  the  Terrorism  Risk  Insurance  Program 
(“TRIP”),  consults  with  the  states  regarding  insurance 
matters,  develops  federal  policy  on  aspects  of  international

the  Treasury 

In  addition  to  provisions  of  Dodd-Frank  pertaining  to 
underwriting  mortgages  and  a  consumer’s  ability  to  repay, 
certain  other  federal  laws  also  directly  or  indirectly  impact 
mortgage  insurers,  including  the  Real  Estate  Settlement 
Procedures  Act  of  1974,  the  Homeowners  Protection  Act  of 
1998,  the  Equal  Credit  Opportunity  Act,  the  Fair  Housing 
Act, the Truth In Lending Act, the Fair Credit Reporting Act 
of 1970, and the Fair Debt Collection Practices Act. Among 
other  things,  these  laws  and  their  implementing  regulations 
prohibit payments for referrals of settlement service business, 
require  fairness  and  non-discrimination  in  granting  or 
facilitating  the  granting  of  credit,  govern  the  circumstances 
under which companies may obtain and use consumer credit 
information,  define  the  manner  in  which  companies  may 
pursue  collection  activities,  and  require  disclosures  of  the 
cost of credit and provide for other consumer protections.

GSE Eligible Mortgage Insurer Requirements. GSEs impose 
requirements  on  private  mortgage  insurers  so  that  they  may 
be  eligible  to  insure  loans  sold  to  the  GSEs,  known  as  the 
Private  Mortgage 
Insurer  Eligibility  Requirements 
(“PMIERs”).  The  PMIERs  apply  to  our  eligible  mortgage 
insurers,  but  do  not  apply  to  Arch  Mortgage  Guaranty 
Company, which is not GSE-approved. The PMIERs impose 
limitations  on  the  type  of  risk  insured,  the  forms  and 
insurance  policies  issued,  standards  for  the  geographic  and 
customer  diversification  of  risk,  procedures  for  claims 
handling,  acceptable  underwriting  practices,  standards  for 
certain  reinsurance  cessions  and  financial  requirements, 
among  other  things.  The  financial  requirements  require  an 
eligible mortgage insurer’s available assets to meet or exceed 
“minimum required assets” as of each quarter end. Minimum 
required  assets  are  calculated  from  PMIERs  tables  with 
several  risk  dimensions  including  origination  year,  original 
loan-to-value,  original  credit  score  of  performing  loans,  and 
the delinquency status of non-performing loans. 

Russian  Sanctions.  The  U.S.  first  imposed  sanctions  on  the 
Russian  Federation  following  its  annexation  of  Crimea  in 
2014. Since February 2022, the U.S. has imposed additional 
sanctions  on  Russia  in  response  to  the  Russian  invasion  of 
Ukraine  and  the  ongoing  hostilities.  Given  the  evolving 
situation,  we  are  closely  monitoring  developments  and  the 
sanctions  imposed,  to  ensure  our  business  remains  in 
compliance with any applicable sanctions measures imposed.

General.  The  Prudential  Regulation  Authority  (“PRA”)  and 
the Financial Conduct Authority (“FCA”) regulate insurance 
and  reinsurance  companies  and  the  FCA  regulates  firms 
carrying  on  insurance  distribution  activities  operating  in  the 
U.K. under the Financial Services and Markets Act 2000 (the 
“FSMA”). In May 2004, Arch Insurance (U.K.) was granted 
the relevant permissions for the classes of insurance business 
which  it  underwrites  in  the  U.K.  AMAL  currently  manages 
Arch Syndicate 2012 and Arch Syndicate 1955 pursuant to its 
authorizations  by  the  U.K.  regulators  and  Lloyd’s.  All  U.K. 
companies are also subject to a range of statutory provisions, 
including  the  laws  and  regulations  of  the  Companies  Act 
2006 (as amended) (the “U.K. Companies Act”).

Lloyd’s Supervision. The operations of AMAL (as managing 
agent of Arch Syndicate 2012 and Arch Syndicate 1955) and 
each syndicate’s respective corporate members, are subject to 
the  byelaws  and  regulations  made  by  (or  on  behalf  of)  the 
Council  of  Lloyd’s,  and  requirements  made  under  those 
byelaws.  The  Council  of  Lloyd’s,  established  in  1982  by 
Lloyd’s  Act  1982,  has  overall  responsibility  and  control  of 
Lloyd’s.  Those  byelaws,  regulations  and  requirements 
provide  a  framework  for  the  regulation  of  the  Lloyd’s 
market, 
to 
underwriting  and  claims  operations  of  Lloyd’s  participants. 
The Council of Lloyd’s has discretionary powers to regulate 
corporate members’ underwriting at Lloyd’s. Lloyd’s is also 
subject to the provisions of the FSMA. Lloyd's is authorized 
by  the  PRA  and  regulated  by  the  PRA  and  FCA.  Those 
entities  acting  within  the  Lloyd’s  market  are  required  to 
comply with the requirements of the FSMA and provisions of 
the  PRA’s  or  FCA's  rules,  although  the  PRA  has  delegated 
certain  of  its  powers,  including  some  of  those  relating  to 
prudential requirements, to Lloyd’s. Each corporate member 
of  Lloyd’s  is  required  to  contribute  a  percentage  of  the 
member’s  premium  income  for  each  year  of  account  to  the 
Lloyd’s central fund. The Lloyd’s central fund is available if 
members  of  Lloyd’s  assets  are  not  sufficient  to  meet  claims 
for  which  the  member  is  liable.  Each  corporate  member  of 
Lloyd’s may also be required to contribute to the central fund 
by way of a supplement to a callable layer of up to 5% of the 

corresponding  member’s  premium  income  limit  for  the 
relevant year of account. 

Principles  for  doing  business  at  Lloyd’s  (the  “Principles”) 
replaced  the  Lloyd’s  Minimum  Standards  (the  previous 
regime which set out the Lloyd’s regulatory requirements for 
Lloyd’s  managing  agents)  and  became  effective  from  the 
third quarter of 2022. The Principles set out the fundamental 
responsibilities  expected  of  all  managing  agents,  including 
AMAL,  and  is  the  basis  against  which  Lloyd’s  will  review 
and categorize all syndicates and managing agents in terms of 
their  capacity  and  performance.  While  offering  greater 
flexibility,  the  principles-based  oversight  requires  greater 
reliance on AMAL to interpret and apply the rules.

Financial Resources. The European solvency framework and 
prudential regime for insurers and reinsurers, the Solvency II 
Directive 2009/138/EC (“Solvency II”), took effect in full on 
January  1,  2016.  See  “European  Union—Insurance  and 
Reinsurance  Regulatory  Regime”  below  for  additional 
details.

Arch  Insurance  (U.K.),  and  the  corporate  members  of  Arch 
Syndicate  2012  and  Arch  Syndicate  1955  are  currently 
required to meet economic risk-based solvency requirements 
imposed  under  Solvency  II.  Solvency  II,  together  with 
European Commission “delegated acts” and guidance issued 
by  the  European  Insurance  and  Occupational  Pensions 
Authority  (“EIOPA”)  sets  out  classification  and  eligibility 
requirements,  including  the  features  which  capital  must 
display in order to qualify as regulatory capital. 

On  January  31,  2020,  the  U.K.  withdrew  from  the  EU  with 
the  terms  of  Brexit  set  forth  in  the  Withdrawal  Agreement 
agreed by the U.K. Parliament and the EU Parliament. At the 
expiration  of  the  transition  period  from  January  31,  2020 
until  December  31,  2020  (the  “Transition  Period”),  during 
which time the U.K. remained in the EU customs union and 
single  market,  the  European  Union  (Withdrawal)  Act  2018, 
transposed  all  applicable  direct  EU 
as  amended,  has 
legislation  into  domestic  U.K.  law,  thus  ensuring  the 
continuing  application  of  Solvency  II  under  the  U.K.’s 
financial services regulatory regime.

In  November  2022,  HM  Treasury  set  out 
government’s  final  reform  package  on  the  Solvency  II 
framework in the U.K., in response to an earlier consultation 
paper from April 2022. Significant changes to be introduced 
by  these  reforms  included  the  reduction  in  risk  margin  by 
30% for non-life insurers and the proposal to remove branch 
capital  requirements.  This  will  benefit  branches  of  foreign 
insurers based in the U.K. immediately upon implementation, 
as  well  as  reduce  barriers  for  foreign  insurers  wishing  to 
establish  a  U.K.  branch  in  the  future.  The  U.K.  government 
has also decided to introduce a new mobilization scheme for

FSMA  2023  provides  a  framework  for  the  revocation  of 
retained  EU  law  in  financial  services  and  its  replacement 
with corresponding regulators’ rules (in the case of Solvency 
II,  mainly  in  the  PRA’s  Rulebook).  Since  the  Transition 
Period, Solvency II has been subject to a major review in its 
application in the U.K., corresponding with a parallel review

Restrictions  on  Acquisition  of  Control.  Under  FSMA,  the 
prior consent of the PRA or FCA, as applicable, is required, 
before  any  person  can  become  a  controller  or  increase  its 
including  Arch 
control  over  any  regulated  company, 
Insurance  (U.K.),  or  over  the  parent  undertaking  of  any 
regulated  company.  Therefore,  the  PRA's  or  FCA's  prior 
consent,  as  applicable,  is  required  before  any  person  can 
become  a  controller  of  Arch  Capital.  Prior  consent  is  also 
required  from  Lloyd’s  before  any  person  can  become  a 
controller or increase its control over a corporate member or 
a  managing  agent  or  a  parent  undertaking  of  a  corporate 
member or managing agent. A controller is defined for these 
purposes  as  a  person  who  holds  (either  alone  or  in  concert 
with others) 10% or more of the shares or voting power in the 
relevant company or its parent undertaking.

Restrictions on Payment of Dividends. Under English law, all 
companies  are  restricted  from  declaring  a  dividend  to  their 
shareholders  unless 
for 
distribution.”  The  calculation  as  to  whether  a  company  has 

they  have  “profits  available 

sufficient profits is based on its accumulated realized profits 
minus  its  accumulated  realized  losses.  U.K.  insurance 
regulatory laws do not prohibit the payment of dividends, but 
the  PRA  or  FCA,  as  applicable,  requires  that  insurance 
companies,  insurance  intermediaries  and  other  regulated 
entities  maintain  certain  solvency  margins  and  may  restrict 
the  payment  of  a  dividend  by  Arch  Insurance  (U.K.)  or 
AMAL, for example.

European  Union  Considerations.  During  the  Transition 
Period,  there  was  no  change  in  passporting  rights  for 
financial institutions in the U.K. Under our Brexit plan, since 
January  2020  nearly  all  of  the  EEA  insurance  business  of 
Arch Insurance (U.K.) has been conducted by Arch Insurance 
(EU).  As  part  of  our  Brexit  planning,  and  in  advance  of  the 
Transition  Period  expiring,  a  transfer  of  the  EEA  legacy 
business 
from  Arch

Economic  relations  between  the  U.K.  and  the  EU  are  now 
governed  by  a  Trade  and  Cooperation  Agreement  (the 
“TCA”).  Following  a  report  published  by  the  European 
Affairs Committee in June 2022, which found that the TCA 
is  limited  in  scope  and  silent  as  to  EU  equivalence  in 
decisions  over  financial  services,  a  Memorandum  of 
Understanding  (“MoU”)  on  regulatory  cooperation  between 
the U.K. and the EU was signed in June 2023. However, the 
MoU does not impose binding substantive commitments nor 
is there any mention of taking forward the commitment in the 
Political  Declaration  accompanying  the  TCA  regarding 
mutual  equivalence.  As  a  result,  under  the  provisions  of  the 
institutions  (including  our  Irish 
TCA,  EEA  financial 
operating  subsidiaries)  lost  their  passporting  rights  into  the 
U.K. Absent any future agreement between the U.K. and the 
EU  on  the  provision  of  financial  services  into  the  U.K.,  the 
post-Brexit  status  and  rules  applicable  to  U.K.  branches  of 
EEA  financial  institutions  will  be  primarily  driven  by  U.K.

The  ability  of  U.K.  firms  (including,  Arch  Insurance  (U.K.) 
and AMAL) to continue doing business in the EEA similarly 
depends  on  applicable  EEA  state  local  law  and  regulation. 
There  has  been  no  decision  yet  made  by  the  European 
Commission on whether or not the U.K.’s financial services 
regulatory  regime  will  be  granted  third-country  equivalence 
for  the  purposes  of  reinsurance,  solvency  calculation  and/or 
group supervision under Solvency II. In the absence of such 
declarations,  U.K.  firms  are  subject  to  more  stringent 
requirements in carrying out reinsurance business with EEA 
firms.  See  “Risk  Factors—Risks  Relating  to  Our  Industry, 
Business  and  Operations—New  legislation  or  regulations 
relating  to  the  U.K.’s  withdrawal  from  the  EU  could 
adversely affect us.”

ESG  Considerations.  The  U.K.  government  has  a  long-term 
ambition to “green” the financial system and align it with the 
U.K.’s  2050  “Net  Zero”  target  (i.e.,100%  greenhouse  gas 
emissions reduction) under the Climate Change Act 2008. As 
part  of  those  efforts,  on  January  17,  2022,  the  U.K.  passed 
mandatory  climate  related  financial  disclosure  requirements 
under  the  Companies  (Strategic  Report)  (Climate-related 
Financial  Disclosure)  Regulations  2022.  The  regulations 
apply  to  large  companies  (including  some  of  our  U.K. 
entities) for financial years starting on or after April 6, 2022. 
The  regulations  generally  align  risk  disclosures  with  the 
the  Taskforce  on  Climate-related 
recommendations  of 
Financial Disclosures (“TCFD”).

In 2021, the U.K. government published its Greening Finance 
Roadmap  to  Sustainable  Investing  (the  “Roadmap”),  which 
announced  proposals  to  extend  the  scope  of  the  U.K.’s 
sustainable  finance  framework  beyond  climate  change. 
Further  to  the  Roadmap,  the  FCA  issued  its  final  Policy 
Statement  on  its  sustainability  disclosure  requirements  and 
the  investment  labels  regime.  The  FCA  is,  among  other 
things,  introducing  a  general  ‘anti-greenwashing’  rule  to 
clarify  that  sustainability-related  claims  must  be  clear,  fair 
and  not  misleading.  The  general  ‘anti-greenwashing’  rule 
comes  into  force  on  May  31,  2024  and  the  FCA  is  also 
consulting  on  new  guidance  on  the  expectations  for  FCA-
authorized  firms  subject  to  the  general  ‘anti-greenwashing 
rule’ which will take effect at the same time.

In  October  2023,  the  Green  Technical  Advisory  Group 
("GTAG") published its final advice to the U.K. government 
on the development of the U.K. Green Taxonomy. Whilst not 
binding,  the  GTAG  advice  gives  a  likely  indication  as  to 
what  the  U.K.  Green  Taxonomy  may  look  like  and  how  it 
might  differ  from  the  EU  Sustainable  Finance  Taxonomy 
Regulation  (“EU  Taxonomy”).  The  GTAG  final  report 
outlines  sustainable  governance  arrangements  for  the  U.K. 
Green  Taxonomy  and  sets  out  various  options  for  achieving 
this.  The  recommended  “least  regrets”  option  involves  the 
U.K.  government  establishing  an  advisory  body  to  facilitate 
implementation  and  development.  If  the  GTAG  advice  is 

adopted, the U.K. Green Taxonomy should align with the EU 
Taxonomy  except  where  doing  so  impact  the  simplicity  or 
usability of the activity classification system or increases the 
risk of greenwashing.

On  December  14,  2022,  the  U.K.  government  said  it  would 
delay  secondary  legislation  under  the  taxonomy  regulations 
(originally anticipated by the end of 2022). Instead, the U.K. 
will restate EU law around the taxonomy and take additional 
time to decide the U.K.’s approach. In addition, Lloyd’s has 
that  managing  agents  must  create  an  ESG 
mandated 
framework  and  strategy,  which  was  to  be  considered  in  the 
2023 business planning cycle. Lloyd’s has also imposed ESG 
focused outcomes by way of the Principles with a particular 
focus  on  culture,  investment  and  underwriting  profitability. 
See “Lloyd’s Supervision” above for additional details.

Russian Sanctions. Since the Russian invasion of Ukraine in 
February  2022,  the  U.K.  government  has  instituted  a  new 
sanctions  regime  targeting  Russia.  The  sanctions  imposed 
include  prohibitions  on  providing 
services 
(including  insurance  and  reinsurance)  to  persons  connected 
with  Russia  in  relation  to  certain  restricted  goods  and 
services,  and  the  freezing  of  assets  owned  or  controlled  by 
designated  persons.  The  U.K.,  U.S.  and  EU  often  consult 
with  each  other  with  respect  to  their  respective  sanctions 
programs.

the  GDPR  and 

Privacy  and  Cybersecurity.  The  U.K.  has  implemented  the 
European General Data Protection Regulation (“EU GDPR”) 
as  the  U.K.  GDPR  which  sits  alongside  the  U.K.  Data 
Protection  Act  2018  (the  “U.K.  GDPR”).  The  U.K.  GDPR 
has direct effect where an entity is established in the U.K. (as 
applicable)  and  has  extra-territorial  effect  where  an  entity 
established  outside  of  the  U.K.  processes  personal  data  in 
relation to the offering of goods or services to individuals in 
the EEA and/or the U.K. or the monitoring of their behavior. 
The  U.K.  GDPR 
imposes  obligations  on  controllers, 
including,  among  others:  (i)  accountability  and  transparency 
requirements, requiring controllers to demonstrate and record 
compliance  with 
to  provide  detailed 
information  to  individuals  regarding  the  processing  of  their 
personal  data;  (ii)  requirements  to  process  personal  data 
lawfully  including  specific  requirements  for  obtaining  valid 
consent  where  consent  is  the  legal  basis  for  processing;  (iii) 
obligations  to  consider  data  protection  when  any  new 
products  or  services  are  developed  and  designed  (e.g.,  to 
limit the amount of personal data processed); (iv) obligations 
to comply with individuals’ data protection rights including a 
right: (a) of access to, erasure of, or rectification of personal 
data, (b) to restriction of processing or to withdraw consent to 
processing, (c) to object to processing or to ask for a copy of 
personal data to be provided to a third party, and (d) not to be 
subject  to  solely  automated  decision-making;  and  (v)  an 
obligation  to  report  personal  data  breaches  to:  (i)  the  data 
protection supervisory authority without undue delay (and no

data  breach,  unless  the  personal  data  breach  is  unlikely  to 
result in a risk to the data subjects’ rights and freedoms; and 
(ii)  affected  individuals,  where  the  personal  data  breach  is 
likely  to  result  in  a  high  risk  to  their  rights  and  freedoms. 
Processors are required to notify the controller without undue 
delay after becoming aware of a personal data breach.

The  U.K.  GDPR  also  imposes  similar  international  data 
transfer  restrictions  to  the  EU  (see  below)  on  transfers  of 
personal  data  from  the  U.K.  to  jurisdictions  that  the  U.K. 
government  does  not  consider  adequate,  including  the  U.S. 
The U.K. government has published its own form of the EU 
Standard  Contractual  Clauses  (“SCCs”),  known  as  the 
International  Data  Transfer  Agreement  and  an  International 
Data  Transfer  Addendum  to  the  new  EU  SCCs.  Further,  on 
September  21,  2023,  the  U.K.  Government  established  a 
U.K.-U.S. data bridge or adequacy decision, through the U.K. 
extension to the EU-U.S. Data Privacy Framework (“DPF”). 
Effective  as  of  October  12,  2023,  U.S.  organizations  which 
self-certify  to  the  DPF  can  now  transfer  personal  data  from 
the U.K. to the U.S. without using SCCs.

The  U.K.  Information  Commissioner’s  Office  (“ICO”)  has 
the power under the GDPR to (amongst other things) impose 
fines  for  serious  breaches  of  up  to  the  higher  of  4%  of  the 
organization’s  annual  worldwide  turnover  or  £17.5  million. 
Individuals  also  have  a  right  to  compensation,  as  a  result  of 
an  organization’s  breach  of  the  U.K.  GDPR  which  has 
affected  them,  for  financial  or  non-financial  losses  (e.g., 
distress). 

Cybersecurity requirements are laid down in the U.K. GDPR, 
which  requires  controllers  and  processors  to  implement 
appropriate

safeguard  personal  data  to  a  level  of  security  appropriate  to 
the data protection risk.

technical  and  organizational  measures 

The  U.K.  GDPR  does  not  provide  for  a  specific  set  of 
cybersecurity  requirements  or  measures  to  be  implemented, 
but  rather  requires  a  controller  or  processor  to  implement 
appropriate  cyber  and  data  security  measures  in  accordance 
with  the  then-current  risk,  the  state  of  the  art,  the  costs  of 
implementation  and  the  nature,  scope,  context  and  purposes 
of  the  processing.  The  U.K.  GDPR  however  does  explicitly 
require  that  controllers  notify  personal  data  breaches  under 
certain circumstances.

Artificial  Intelligence.  The  U.K.  has  adopted  a  “soft  law” 
approach to AI regulation meaning it has not adopted formal 
legislation to regulate AI but has adopted soft law guidelines 
in the form of a White Paper published on March 29, 2023. 
The  U.K.  intends  to  develop  a  sector-specific,  principle 
centered approach to AI regulation, with the relevant sectors 
being responsible for enforcement.

Ireland 

General.  The  CBI  regulates  insurance  and  reinsurance 
companies  and  intermediaries  authorized  in  Ireland.  Our 
three  Irish  operating  subsidiaries  are  Arch  Re  Europe,  Arch 
Insurance  (EU)  and  Arch  Underwriters  Europe  Limited 
(“Arch Underwriters Europe”). Arch Re Europe was licensed 
and authorized by the CBI as a non-life reinsurer in October 
2008  and  as  a  life  reinsurer  in  November  2009.  Arch 
Insurance (EU) was licensed and authorized by the CBI as a 
non-life  insurer  in  December  2011.  As  part  of  our  Brexit 
plan, Arch Insurance (EU) received approval from the CBI to 
expand  the  nature  of  its  business  in  2019  and  commenced 
writing expanded insurance lines in the EEA in 2020 with the 
Part  VII  Transfer  completed  at  the  end  of  December  2020. 
Arch  Underwriters  Europe  was  registered  by  the  CBI  as  an 
insurance  and  reinsurance  intermediary  in  July  2014.  Arch 
Re  Europe,  Arch  Insurance  (EU)  and  Arch  Underwriters 
Europe  are  subject  to  the  supervision  of  the  CBI  and  must 
comply  with  Irish  insurance  acts  and  regulations  as  well  as 
with directions and guidance issued by the CBI.

Arch  Re  Europe  and  Arch  Insurance  (EU)  are  required  to 
comply with Solvency II requirements. See “European Union 
—Insurance and Reinsurance Regulatory Regime” below for 
additional  details.  As  an  intermediary,  Arch  Underwriters 
Europe is subject to a different regulatory regime and is not 
subject  to  solvency  capital  rules  but  must  comply  with 
requirements  such  as  to  maintain  professional  indemnity 
insurance  and  to  have  directors  that  are  fit  and  proper.  Our 
Irish subsidiaries are also subject to the general body of Irish 
company laws and regulations including the provisions of the 
Companies Act 2014.

The  CBI  operates  a  risk-based  supervision  framework, 
entitled PRISM, in respect to its regulation of Irish regulated 
entities.  Under  PRISM,  the  CBI  applies  an  impact  rating  to 
each entity it regulates, ranging from Low to High, based on 
the nature, scale and complexity of its business. The level of 
supervision  applied  by  the  CBI  is  commensurate  with  the 
impact rating applied under PRISM with higher rated entities 
subject  to  more  focused  supervision  engagement  from  the 
CBI on a more frequent basis. 

Financial  Resources.  Arch  Re  Europe  and  Arch  Insurance 
(EU)  are  required  to  meet  economic  risk-based  solvency 
requirements  imposed  under  Solvency  II.  Solvency  II, 
together  with  European  Commission  “delegated  acts”  and 
guidance  issued  by  EIOPA  sets  out  classification  and 
eligibility  requirements,  including  the  features  which  capital 
must display in order to qualify as regulatory capital.

Restrictions  on  Acquisitions.  Under  Irish  law,  the  prior 
consent of the CBI is required before any person can acquire 
or  increase  a  qualifying  holding  in  an  Irish  insurer  or 
reinsurer,  including  Arch  Insurance  (EU)  and  Arch  Re 

ARCH CAPITAL

27

2023 FORM 10-K

Europe, or their parent undertakings. A qualifying holding is 
defined for these purposes as a direct or indirect holding that 
represents 10% or more of the capital of, or voting rights, in 
the undertaking or makes it possible to exercise a significant 
influence over the management of the undertaking.

Restrictions on Payment of Dividends. Under Irish company 
law,  Arch  Re  Europe,  Arch  Insurance  (EU)  and  Arch 
Underwriters Europe are permitted to make distributions only 
out of profits available for distribution. A company’s profits 
available for distribution are its accumulated, realized profits, 
so  far  as  not  previously  utilized  by  distribution  or 
capitalization, less its accumulated, realized losses, so far as 
not previously written off in a reduction or reorganization of 
capital duly made. Further, the CBI has powers to intervene if 
a  dividend  payment  were  to  lead  to  a  breach  of  regulatory 
capital requirements. 

In  response  to  the  COVID-19  pandemic,  the  CBI  issued 
guidance in April 2020, based on guidance issued by EIOPA, 
that  insurance  firms  postpone  any  payment  of  dividend 
distributions  or  similar  transactions  until  they  can  forecast 
their  costs  and  future  revenues  with  a  greater  degree  of 
certainty.  However,  the  CBI  modified  its  guidance,  with 
effect  from  October  1,  2021,  so  that  the  general  restrictions 
on 
the  payment  of  dividend  distributions  or  variable 
remuneration  are  no  longer  in  place.  The  CBI  still  requires 
(re)insurance  firms  to  notify  it  in  advance  of  any  proposed 
distribution.

Insurance 

European  Union  Considerations.  As  Arch  Re  Europe,  Arch 
Insurance (EU) and Arch Underwriters Europe are authorized 
by  the  CBI  in  Ireland,  a  Member  State  of  the  EU,  those 
authorizations  are  recognized  throughout  the  EEA.  Subject 
only  to  certain  notification  and  application  requirements, 
(EU)  and  Arch 
Arch  Re  Europe,  Arch 
Underwriters  Europe  can  provide  services,  or  establish  a 
branch, in any other Member State of the EEA. Although, in 
doing  so,  they  may  be  subject  to  the  laws  of  such  Member 
States  with  respect  to  the  conduct  of  business  in  such 
Member State, company law registrations and other matters, 
they  will  remain  subject 
to  financial  and  operational 
supervision  by  the  CBI  only.  Arch  Insurance  (EU)  has 
branches in Italy and the U.K. Arch Re Underwriting ApS in 
Denmark  (“Arch  Re  Denmark”)  is  an  underwriting  agency 
underwriting  accident  and  health  and  other  reinsurance 
business  for  Arch  Re  Europe.  Arch  Re  Europe  also  has 
branches  in  the  U.K.  and  Switzerland  (“Arch  Re  Europe 
Swiss Branch”).

From January 1, 2021, under the provisions of the TCA our 
Irish regulated entities have lost their passporting rights into 
the U.K. See “Risk Factors—Risks Relating to Our Industry, 
Business  and  Operations—New  legislation  or  regulations 
relating  to  the  U.K.’s  withdrawal  from  the  EU  could 
adversely affect us.”

ESG  Considerations.  ESG  matters  have  been  on  the  CBI's 
agenda  for  a  number  of  years.  In  November  2021,  the  CBI 
issued its expectations in respect of climate and broader ESG 
issues 
(including 
(re)insurers). The CBI's expectations focus on five key areas: 
governance,  risk  management,  scenario  analysis  (including, 
but  not  limited  to,  stress  testing  for  the  purposes  of  the 
ORSA),  disclosures  and  strategy  and  business  model  risk. 
The CBI has indicated that its expectations will be applied in 
a proportionate manner. In August 2022, the CBI published a 
Consultation  Paper  setting  out  its  proposed  guidance  on 
climate change risk for the (re)insurance sector. The finalized 
guidance  was  published  by  the  CBI  in  March  2023  and 
clarifies  the  CBI’s  expectations  on  how  (re)insurers  should 
address  climate  change  risks  in  their  business  and  to  assist 
(re)insurers  develop  their  governance  and  risk  management 
frameworks  to  do  this.  It  is  expected  that  over  time, 
disclosures in respect to ESG matters may be captured in the 
Solvency  and  Financial  Condition  Reports  of  Arch's  Irish 
entities.  Arch  continues  to  consider  the  impact  of  this 
guidance  on  its  Irish  entities.  See  also  “European  Union  – 
ESG Considerations.”

into  effect 

Irish  Individual  Accountability  Framework  Act  2023.  The 
Central  Bank  (Individual  Accountability  Framework)  Act 
2023  (the  “IAF  Act”)  was  signed  into  law  in  March  2023 
with  the  relevant  provisions  and  obligations  under  the  IAF 
Act  coming  into  effect  on  a  phased  basis.  The  majority  of 
provisions  came 
in  December  2023,  with 
remaining provisions coming into effect on July 1, 2024 and 
July 1, 2025. The IAF Act implements substantive changes to 
the  fitness  and  probity  regime  maintained  by  the  CBI  in 
Ireland  and  imposes  certain  additional  obligations  and 
liability  for  senior  executives  in  Irish  regulated  financial 
service entities, including (re)insurance companies. Arch has 
considered the impact of the IAF Act on its business and has 
catered  for  this  accordingly.  See  Item  1,  “Business—
Regulation, European Union – ESG Considerations.”

Third  Country  Governance  Arrangements.  In  September 
2023,  in  response  to  a  supervisory  statement  issued  by 
EIOPA  in  February  2023  on  the  use  of  third  country 
governance  arrangements 
(such  as  branches)  by  EU 
authorized  (re)insurers,  the  CBI  published  its  formal  views 
on  the  use  of  third  country  governance  arrangements.  The 
CBI’s  key  expectations  are  that  (i)  third  country  branches 
should  primarily  serve  the  market  in  which  they  are 
established, with their sole objective to not simply support an 
Irish  based  (re)insurer  and  (ii)  third  country  governance 
arrangements  should  not  undermine  the  substance  of  Irish 
based  (re)insurers.  The  CBI  instructed  Irish  (re)insurers  to 
review  their  current  business  models  in  light  of  EIOPA’s 
supervisory statement and the CBI’s own expectations. Arch 
reviewed,  and  continues  to  consider,  the  impact  of  this 
supervisory statement on its Irish and European operations.

Insurance  and  Reinsurance  Regulatory  Regime.  Solvency  II 
took  effect  in  full  on  January  1,  2016.  Solvency  II  imposes 
economic  risk-based  solvency  requirements  across  all  EU 
Member  States  and  consists  of  three  pillars:  Pillar  I-
quantitative capital requirements, based on a valuation of the 
entire  balance  sheet;  Pillar  II-qualitative  regulatory  review, 
which  includes  governance,  internal  controls,  enterprise  risk 
management  and  supervisory  review  process;  and  Pillar  III-
market  discipline,  which  is  accomplished  through  reporting 
of  the  insurer’s  financial  condition  to  regulators  and  the 
public.  Solvency 
supplemented  by  European 
Commission  Delegated  Regulation  (EU)  2015/35  (the 
“Delegated  Regulation”),  other  European  Commission 
“delegated  acts”  and  binding 
technical  standards,  and 
guidelines  issued  by  EIOPA.  The  Delegated  Regulation  sets 
out  more  detailed  requirements  for  individual  insurance  and 
reinsurance undertakings, as well as for groups, based on the 
overarching  provisions  of  Solvency  II,  which  together  make 
up  the  core  of  the  single  prudential  rulebook  for  insurance 
and reinsurance undertakings in the EU.

In  December  2020,  EIOPA  provided  an  opinion  to  the 
European  Commission  in  relation  to  the  review  of  the 
Solvency  II  regime.  This  review  was  initiated  by  the 
European Commission to determine whether the Solvency II 
regime  remains  fit  for  purpose.  In  its  opinion,  EIOPA 
confirms  that  the  overall  Solvency  II  framework  is  working 
well  from  a  prudential  perspective,  suggesting  that  there  are 
no  fundamental  changes  needed  but  that  a  number  of 
amendments are required to ensure the regime continues as a 
well-functioning  risk-based  regime.  In  September  2021,  the 
European  Commission  published  legislative  proposals  for 
amendments  to  the  Solvency  II  Directive  arising  out  of 
EIOPA's  review  of  the  Solvency  II  regime.  The  proposed 
amendments 
including 
proportionality,  quality  of  supervision,  sustainability  risks 
and  group  and  cross-border  supervision.  The  European 
Parliament and the Council reached provisional agreement on

approval expected in 2024.

of the Supervisory Statement on its EU operations. See “Risk 
Factors—Risks  Relating  to  Our  Industry,  Business  and 
Operations—New  legislation  or  regulations  relating  to  the 
U.K.’s withdrawal from the EU could adversely affect us.” 

Arch Re Europe and Arch Insurance (EU), being established 
in  Ireland  and  authorized  by  the  CBI,  are  able  to  establish 
branches and provide reinsurance services and, in respect of 
Arch  Insurance  (EU),  insurance  services  in  all  EEA  states. 
This  is  subject  to  certain  regulatory  notifications  and  there 
being  no  objection  from  the  CBI  and  the  Member  States 
concerned.

Solvency  II  does  not  prohibit  EEA  insurers  from  obtaining 
reinsurance from reinsurers licensed outside the EEA, such as 
Arch Re Bermuda. As such, and subject to the specific rules 
in  each  Member  State,  Arch  Re  Bermuda  may  do  business 
from  Bermuda  with  insurers  in  EEA  Member  States,  but  it 
may  not  directly  operate  its  reinsurance  business  within  the 
EEA.  Article  172  of  Solvency  II  provides  that  reinsurance 
contracts  concluded  by  insurance  undertakings  in  the  EEA 
with  reinsurers  having  their  head  office  in  a  country  whose 
solvency  regime  has  been  determined  to  be  equivalent  to 
Solvency  II  shall  be  treated  in  the  same  manner  as 
reinsurance  contracts  with  undertakings 
the  EEA 
authorized  under  Solvency  II.  From  January  1,  2016, 
Bermuda  was  deemed  by  the  European  Commission  to  be 
equivalent  for  Solvency  II  purposes.  Solvency  II  also 
includes  specific  measures  providing  for  the  supervision  of 
insurance  and 
reinsurance  groups.  However,  as  a 
consequence  of  the  above  determination  of  equivalence, 
pursuant to Article 260 of Solvency II, regulators within the 
EEA are required to rely on the worldwide group supervision 
exercised by the BMA. EIOPA has also indicated that, on a 
case  by  case  basis,  groups  subject  to  this  worldwide 
supervision  may  be  exempted  from  any  EEA  sub-group

The  IDD  was  published  in  February  2016.  EEA  Member 
States  were  required  to  transpose  the  IDD  by  October  1, 
2018.  The  IDD  replaces  the  existing  Insurance  Mediation 
Directive.  The  IDD  applies  to  all  distributors  of  insurance 
and  reinsurance  products  (including  insurers  and  reinsurers 
selling  directly  to  customers)  and  strengthens  the  regulatory 
regime applicable to distribution activities through increased 
transparency,  information  and  conduct  requirements.  The 
principal  impact  of  the  IDD  is  on  the  insurance  market, 
however,  requirements  that  apply  across  insurance  and 
include  more  specific  conditions  regarding 
reinsurance 
knowledge  and  continuing  professional  development  for 
those involved in distribution of (re)insurance products. The 
IDD  continues  the  pre-existing  ability  of  intermediaries 
established in a Member State of the EU to establish branches 
and  provide  services  to  all  EEA  states.  Arch  Underwriters 
Europe,  being  established  in  Ireland  and  authorized  by  the 
CBI,  is  able,  subject  to  regulatory  notifications  and  there 
being  no  objection  from  the  CBI,  to  establish  branches  and 
provide services in all EEA states.

Privacy  and  Cybersecurity.  The  EU  GDPR  came  into  effect 
on May 25, 2018. The EU GDPR governs the collection, use, 
disclosure,  transfer  or  other  processing  of  personal  data.  Its 
scope extends to certain entities not established in the EEA if 
they  process  personal  data  or  offer  goods  or  services  to,  or 
monitor  the  behavior  of,  EEA  data  subjects.  The  EU  GDPR 
contains  a  number  of  requirements  regarding  the  processing 
of  personal  data  about  individuals,  including  mandatory 
security  breach  reporting,  new  and  strengthened  individual 
rights, 
for 
compliance with the GDPR principles (including fairness and 
transparency),  maintenance  of  data  processing  activity 
records  and  the  implementation  of  “privacy  by  design,” 
including 
the  completion  of  mandatory  Data 
Protection Impact Assessments in connection with higher risk 
data processing activities.

Commission  does  not  recognize  as  having  “adequate”  data 
protection laws. In particular, on July 16, 2020, the Court of 
Justice of the EU (Court of Justice) in Schrems II invalidated 
the European Union-United States (EU-U.S.) Privacy Shield 
on the grounds that the EU-U.S. Privacy Shield failed to offer 
adequate  protections  to  EU  personal  information  transferred 
to the U.S. While the Court of Justice upheld the use of other 
data  transfer  mechanisms,  such  as  the  Standard  Contractual 
Clauses  (“EU  SCCs”),  the  decision  has  led  to  some 
uncertainty  regarding  the  use  of  such  mechanisms  for  data 
transfers to the U.S., and the Court of Justice made clear that 
reliance on EU SCCs alone may not necessarily be sufficient 

in  all  circumstances.  The  European  Data  Protection  Board 
issued  additional  guidance  regarding  international  transfers 
which may require us to implement additional safeguards to 
further  enhance  the  security  of  data  transferred  out  of  the 
EEA. The European Commission published new versions of 
the EU SCCs in June 2021, which place onerous obligations 
on  the  parties.  On  October  7,  2022,  the  U.S.  President 
introduced  an  Executive  Order  to  facilitate  a  new  Trans-
Atlantic Data Privacy Framework to act as a successor to the 
invalidated  EU-U.S.  Privacy  Shield.  On  July  10,  2023,  the 
European Commission adopted an adequacy decision relating 
to the transfer of personal data from the EU to the U.S. which 
takes  place  under  the  DPF.  The  DPF  is  the  successor  to  the 
EU-U.S.  Privacy  Shield  and  allows  companies 
that 
participate in the DPF to transfer personal data freely to the 
U.S. without the need for alternative data protection transfer 
mechanisms (such as SCCs or binding corporate rules).

The  EU  GDPR  imposes  substantial  fines  for  breaches  and 
violations  (up  to  the  greater  of  €20  million  or  4%  of  global 
turnover). The EU GDPR allows data subjects and consumer 
associations to lodge complaints with supervisory authorities, 
seek judicial remedies and obtain compensation for damages 
resulting from violations of the EU GDPR.

Cybersecurity  and  information  security  are  an  area  of 
increasing  focus  for  the  EU.  The  Digital  Operational 
Resilience Act (“DORA”) entered into force in January 2023. 
The  core  aim  of  DORA  is  to  prevent  and  mitigate  cyber 
threats  and  sets  uniform  requirements  for  the  security  of 
network  and  information  systems  of  financial  sector  entities 
(including (re)insurers) as well as critical third parties which 
provide  ICT  (information  and  communication  technology)-
related  services,  such  as  cloud  platforms  or  data  analytics 
services. In scope entities will be required to comply with the 
obligations set out under DORA from January 2025.

In addition to the above, EIOPA continues to publish detailed 
guidelines,  recommendations  and  expectations  relating  to 
cyber  matters  and  how  these  should  be  managed  and 
considered by the (re)insurance sector.

Artificial  Intelligence.  On  December  9,  2023,  the  EU 
Parliament and Council reached provisional agreement on the 
text of the Artificial Intelligence Act (the “EU AI Act”). The 
EU AI Act aims to regulate AI and will apply directly, on a 
phased  basis,  in  all  EU  Member  States.  In  February  2024, 
representatives  of  the  governments  of  EU  Member  States 
signed off on the final text of the EU AI Act. A vote in the 
European  Parliament  on  the  adoption  of  the  EU  AI  Act  is 
expected in April 2024.

The EU AI Act will introduce a categorization system for AI 
risks  with  the  level  of  protection  linked  to  the  level  of  risk 
posed by the relevant AI. Based on the final text, certain AI 
applications utilized by (re)insurers will fall within the scope

In  February  2022,  the  European  Commission  adopted  a 
proposal  for  the  Corporate  Sustainability  Due  Diligence 
Directive  (“CSDD”).  Provisional  agreement  was  reached 
between  the  European  Parliament  and  Council  in  December 
2023 however the text of the agreed CSDD has not yet been 
officially  published.  Formal  approval  of  the  CSDD  is 
expected to be provided in early 2024. While the main focus 
of the CSDD is on conducting due diligence on human rights 
and  environmental  impacts  within  a  company  and  across  its 
there  are  also  additional  sustainability 
value  chain, 
requirements  for  certain  in-scope  entities.  It  is  anticipated 
that  certain  obligations  under  the  CSDD  will  apply  to 
financial  services  entities  (including  (re)insurers)  however  it 
is  expected 
that  financial  services  entities  (including 
(re)insurers) will be temporarily excluded from the obligation 
to  conduct  due  diligence  on  their  customers.We  will  closely 
monitor  the  continued  development  of  the  CSDD  and  its 
potential impact on Arch’s European operations.

In tandem with all of the above, EIOPA continues to engage 
with  stakeholders  in  the  (re)insurance  sector  and  publish 
detailed  guidelines, 
recommendations  and  expectations 
relating  to  ESG  matters  and  how  these  should  be  managed 
and considered by the (re)insurance sector.

Russian Sanctions. Since February 2022, the EU has imposed 
significant sanctions on the Russian Federation in response to 
its invasion of Ukraine. These sanctions are similar to those 
imposed by the U.K. and U.S. Given the evolving situation,

continues  to  monitor  development  of  the  EU  AI  Act  and  its

ESG Considerations. A comprehensive package of measures 
to  facilitate  the  progression  towards  sustainable  economic 
activities  was  approved  in  principle  by  the  European 
Commission  in  April  2021.  In  August  2021,  two  delegated 
regulations  (the  “EC  Regulations”)  amending  sectoral 
legislation, including the Solvency II Directive and the IDD, 
were published. The EC Regulations focus on the integration 
of  sustainability 
including  product 
into  key  activities 
oversight  and  governance,  risk  management  and  suitability 
assessment  procedures.  The  EC  Regulations  apply  from 
August 2022. 

The Corporate Sustainability Reporting Directive (“CSRD”), 
which  replaces 
the  Non-Financial  Reporting  Directive 
(“NFRD”),  was  published  in  the  Official  Journal  of  the  EU 
on November 16, 2022 and entered into effect on January 5, 
2023.  Certain  of  our  European  subsidiaries  are  subject  to 
NFRD.  The  CSRD  expands  the  scope  of  sustainability 
reporting obligations to any European listed company or any 
company  (including  (re)insurers)  meeting  certain  criteria. 
Companies  which  are  already  subject  to  NFRD  must  start 
reporting relevant information for financial years starting on 
or  after  January  1,  2024  beginning  in  2025.  Reporting 
obligations for other companies fulfilling certain criteria will 
commence  in  2026  for  financial  years  starting  on  or  after 
January  1,  2025.  In  addition,  the  reporting  standards  under 
the  CSRD,  which  provides  in-scope  companies  with  the 
technical  detail  on  the  information  that  will  need  to  be 
disclosed  and  reported,  were  adopted  by  the  European 
Commission  in  July  2023.  Certain  of  our  European  entities 
will  fall  within  the  scope  of  certain  reporting  obligations 
under the CSRD.

An additional ESG framework, the EU Taxonomy, came into 
force  in  July  2020,  with  in-scope  companies  required  to 
comply  with  certain  reporting  obligations  from  January  1, 
2022. The EU Taxonomy (which is a classification standard 
for  reporting)  sets  out  six  environmental  objectives  with 
which  companies'  economic  activities  must  comply  if  they 
are to be described as environmentally sustainable. These six 
environmental  objectives  are:  (1)  climate  change  mitigation, 
(2)  climate  change  adaptation,  (3)  sustainable  use  and 
protection  of  water  and  marine  resources,  (4)  transition  to  a 
circular  economy,  (5)  pollution  prevention  and  control  and 
(6)  the  protection  and  restoration  of  biodiversity  and 
ecosystems.  In  addition,  reporting  obligations  apply  to  in-
scope  companies  regarding  (1)  the  financial  products  they 
provide  and  (2)  the  environmental  sustainability  of  an  in-
scope  company's  activities,  which  is  to  be  disclosed  in  non-
financial  statements  that  are  required  under  the  NFRD  and 
the CSRD.

In December 2008, Arch Re Europe opened Arch Re Europe 
Swiss  Branch  as  a  branch  office.  As  Arch  Re  Europe  is 
domiciled outside of Switzerland and its activities are limited

Taxation of Arch Capital

Bermuda. Under current Bermuda law, Arch Capital does not 
pay  any  tax  on  income  or  profits,  and  is  not  subject  to 
payment  of  any  tax  on  withholding,  capital  gains  or  capital 
transfers.  Arch  Capital  has  obtained  from  the  Minister  of 
Finance  under  the  Exempted  Undertakings  Tax  Protection 
Act  1966  of  Bermuda  an  assurance  that,  in  the  event  that 

Bermuda  enacts  legislation  imposing  tax  computed  on 
profits, income, any capital asset, gain or appreciation, or any 
tax in the nature of estate duty or inheritance, the imposition 
of any such tax shall not be applicable to Arch Capital or to 
any  of  our  operations  or  our  shares,  debentures  or  other 
obligations until March 31, 2035. However, on December 27, 
2023, the Government of Bermuda enacted the Bermuda CIT 
Act, which will become effective for tax years beginning on 
or  after  January  1,  2025.  Given  the  potential  for  the  new 
corporate  income  tax  regime  in  Bermuda  to  supersede  the 
Minister  of  Finance’s  assurance,  the  Company  is  likely  to 
become subject to taxes in Bermuda before March 31 ,2035. 
See  Item  1A,“Risk  Factors  —  Risks  Relating  to  Taxation” 
for  additional 
information.  We  pay  annual  Bermuda 
government fees, and our Bermuda insurance and reinsurance 
subsidiary pays annual insurance license fees. In addition, all 
entities  employing  individuals  in  Bermuda  are  required  to 
pay a payroll tax and other sundry taxes payable, directly or 
indirectly, to the Bermuda government.

United  States.  Arch  Capital  and  its  non-U.S.  subsidiaries 
believe  they  have  conducted  their  operations  and  currently 
intend to conduct their operations going forward in a manner 
that has not caused them and will not cause them to be treated 
as engaged in a trade or business in the U.S. and, therefore, 
has  not  been  and  will  not  be  required  to  pay  U.S.  federal 
income taxes (other than U.S. excise taxes on insurance and 
reinsurance  premiums  and  withholding  taxes  on  dividends 
and certain other U.S. source investment income). However, 
because definitive identification of activities which constitute 
being  engaged  in  a  trade  or  business  in  the  U.S.  is  not 
provided by the Internal Revenue Code of 1986, as amended 
(the  “Code”),  U.S.  Treasury 
(“Treasury 
Regulations”)  or  court  decisions,  there  can  be  no  assurance 
that  our  position  on  being  engaged  in  a  trade  or  business  in 
the  U.S.  is  correct.  A  foreign  corporation  deemed  to  be  so 
engaged would be subject to U.S. federal income tax, as well 
as  the  branch  profits  tax,  on  its  income,  which  is  treated  as 
effectively  connected  with  the  conduct  of  that  trade  or 
business unless the corporation is entitled to relief under a tax 
treaty.  Such  income  tax,  if  imposed,  would  be  based  on 
effectively  connected 
in  a  manner 
generally  analogous  to  that  applied  to  the  income  of  a 
domestic  corporation,  except  that  deductions  and  credits 
generally are not permitted unless the foreign corporation has 
timely  filed  a  U.S.  federal  income  tax  return  in  accordance 
with  applicable  Treasury  Regulations.  Penalties  may  be 
assessed  for  failure  to  file  tax  returns.  In  addition,  in  such 
case,  a  30%  branch  profits  tax  would  be  imposed  on  net 
income after subtracting the regular corporate tax and making

to  meet  certain  liabilities  to,  persons  who  are  not  Bermuda 
residents  or  U.S.  citizens  or  residents.  While  Arch  Capital 
believes  that  its  Bermuda  insurance  subsidiaries  have  been 
eligible for Treaty benefits to date, there can be no assurance 
that  this  is  the  case  or  that  the  Bermuda  insurance 
subsidiaries will continue to be eligible for Treaty benefits.

The  Treaty  clearly  applies  to  premium  income  but  may  be 
construed  as  not  protecting  investment  income.  If  Arch 
Capital’s Bermuda insurance subsidiaries were considered to 
be  engaged  in  a  U.S.  trade  or  business  and  were  entitled  to 
the benefits of the Treaty in general, but the Treaty were not 
found  to  protect  investment  income,  a  portion  of  such 
subsidiaries’  investment  income  could  be  subject  to  U.S. 
federal income tax.

Non-U.S.  insurance  companies  carrying  on  an  insurance 
business within the U.S. have a certain minimum amount of 
effectively  connected  net  investment  income,  determined  in 
accordance  with  a  formula  that  depends,  in  part,  on  the 
amount of U.S. risk insured or reinsured by such companies. 
If  any  of  Arch  Capital's  non-U.S.  insurance  subsidiaries  is 
considered  to  be  engaged  in  the  conduct  of  an  insurance 
business in the U.S., a significant portion of such subsidiary’s 
investment  income  could  be  subject  to  U.S.  federal  income 
tax.

Non-U.S. corporations not engaged in a trade or business in 
the U.S. are nonetheless subject to U.S. income tax on certain 
“fixed  or  determinable  annual  or  periodic  gains,  profits  and 
income” derived from sources within the U.S. as enumerated 
in Section 881(a) of the Code (such as dividends and certain 
interest on investments), subject to exemption under the Code 
or reduction by an applicable treaty.

The  U.S.  also  imposes  an  excise  tax  on  insurance  and 
reinsurance premiums paid to non-U.S. insurers or reinsurers 
with  respect  to  risks  located  in  the  U.S.  The  rates  of  tax, 
unless  reduced  by  an  applicable  U.S.  tax  treaty,  are  4%  for 
non-life  insurance  premiums  and  1%  for  life  insurance  and 
all reinsurance premiums.

The Tax Cuts and Jobs Act of 2017 (the “Tax Cuts Act”) was 
signed into law by the President of the United States in 2017. 
For  taxable  years  beginning  after  2017,  the  Tax  Cuts  Act 

imposes  a  10%  minimum  base  erosion  and  anti-abuse  tax 
(increased  to  12.5%  for  taxable  years  after  2025)  on  the 
“modified  taxable  income”  of  a  U.S.  corporation  (or  a  non-
U.S.  corporation  engaged  in  a  U.S.  trade  or  business)  over 
such  corporation’s  regular  U.S.  federal  income  tax,  reduced 
by  certain  tax  credits.  The  “modified  taxable  income”  of  a 
corporation  is  determined  without  deduction  for  certain 
payments  by  such  corporation  to  its  non-U.S.  affiliates

United  Kingdom.  Our  U.K.  subsidiaries  are  companies  that 
are  incorporated  and  have  their  central  management  and 
control in the U.K. and are therefore resident in the U.K. for 
corporation tax purposes. As a result, they are subject to U.K. 
corporation tax on their respective profits. The U.K. branches 
of  Arch  Re  Europe  and  Arch  Insurance  (EU)  are  subject  to 
U.K. corporation tax on the profits (both income profits and 
chargeable  gains)  attributable  to  each  branch.  The  blended 
rate  of  U.K.  corporation  tax  for  the  2023  financial  year  is 
approximately 23.5% on profits (the rate increased from 19% 
to 25% with effect from April 1, 2023). 

Canada.  Arch  Insurance  Canada  is  taxed  on  its  worldwide 
income.  Arch  Re  U.S.  is  taxed  on  its  net  business  income 
earned  in  Canada.  The  general  federal  corporate  income  tax 
rate  in  Canada  is  currently  15%.  Provincial  and  territorial 
corporate  income  tax  rates  are  added  to  the  general  federal 
corporate income tax rate and generally vary between 8% and 
16%.

Ireland.  Each  of  Arch  Re  Europe,  Arch  Insurance  (EU)  and 
Arch  Underwriters  Europe  is  incorporated  and  resident  in 
Ireland  for  corporation  tax  purposes  and  will  be  subject  to 
Irish corporate tax on worldwide profits, including the profits 
of the branches of Arch Re Europe, Arch Insurance (EU) and 
Arch Underwriters Europe. Any foreign branch corporate tax 
payable 
is  creditable  against  Arch  Re  Europe’s  Irish 
corporate  tax  liability  on  the  results  of  Arch  Re  Europe’s 
branches  with  the  same  principle  applied  to  Arch  Insurance 
(EU)’s  branches  and  Arch  Underwriters  Europe’s  branches. 
The  current  rate  of  Irish  corporation  tax  applicable  to  such 
trading profits is 12.5%.

Switzerland.  Arch  Re  Europe  Swiss  Branch  and  Arch 
Underwriters  Europe  Swiss  Branch  are  subject  to  Swiss 
corporation  tax  on  the  profit  which  is  allocated  to  each 
branch.  The  effective  tax  rate  is  approximately  19.65%  for 
Swiss  federal,  cantonal  and  communal  corporation  taxes  on 
the  profit.  The  effective  tax  rate  of  the  annual  cantonal  and 
communal  capital  taxes  on  the  equity  which  is  allocated  to 
Arch  Re  Europe  Swiss  Branch  and  Arch  Underwriters 
Europe Swiss Branch is approximately 0.17%.

Arch Re Bermuda, is subject to Danish corporation taxes on 
its profits at a rate of 22%.

Hong Kong. Arch MI Asia is subject to Hong Kong corporate 
tax  on  its  assessable  profits  at  a  rate  of  16.5%.  Assessable 
profits  are  the  net  profits  for  the  basis  period,  arising  in  or 
derived from Hong Kong.

Australia.  Arch  LMI  and  Arch  Indemnity,  Australian

30%.

OECD’s Pillar II.

Under  Pillar  II,  a  global  minimum  tax  at  the  rate  of  15% 
would  be  imposed  on  certain  in-scope  entities.  Under  the 
European  Union’s  minimum  tax  directive,  unanimously 
agreed  by  the  member  states  in  2022,  each  member  state  is 
required  to  adopt  domestic  legislation  implementing  the 
minimum tax rules effective for periods beginning on or after 
December 31, 2023, with the “under-taxed profit rule” to take 
effect for periods beginning on or after December 31, 2024. 
Legislatures  in  multiple  countries  outside  of  the  European 
Union have also drafted legislation to implement the OECD’s 
minimum tax proposal. 

laws 

in  different  manners, 

Given  the  OECD's  continued  release  of  guidance  regarding 
Pillar II, that only certain jurisdictions have currently enacted 
laws  to  give  effect  to  Pillar  II,  and  that  jurisdictions  may 
interpret  such 
the  overall 
implementation  of  Pillar  II  remains  uncertain  and  subject  to 
change,  possibly  on  a  retroactive  basis.  Although  certain 
jurisdictions in which we and our affiliates do business have 
enacted  an  “under-taxed  profit  rule”,  such  rule  is  only 
expected  to  take  effect  for  taxable  periods  beginning  on  or 
after  December  31,  2024.  The  adoption  of  the  tax  laws 
described  above  (in  particular,  the  adoption  of  an  “under-
taxed  profit  rule”  by  certain  countries  in  which  we  and  our 
affiliates do business) are expected to result in an increase to 
our effective tax rate and aggregate tax liability. See Item 1A, 
“Risk  Factors  –  Risk  Relating  to  Taxation”  for  additional 
information.

Taxation of Shareholders

Bermuda. Currently, there is no Bermuda withholding tax on 
dividends paid by us.

United  States—General.  The  following  summary  sets  forth 
certain  U.S.  federal  income  tax  considerations  related  to  the 
purchase,  ownership  and  disposition  of  our  common  shares 
and our non-cumulative preferred shares (“preferred shares”). 
Unless  otherwise  stated,  this  summary  deals  only  with 
shareholders  (“U.S.  holders”)  that  are  U.S.  Persons  (as 
defined  below)  and  to  common  shares  and  preferred  shares

beneficially owned by such holder and held as capital assets. 
The  following  discussion  is  only  a  general  summary  of  the 
U.S.  federal  income  tax  matters  described  herein  and  does 
not  purport  to  address  all  of  the  U.S.  federal  income  tax 
consequences that may be relevant to a particular shareholder 
in  light  of  such  shareholder’s  specific  circumstances.  In 
addition,  the  following  summary  (except  as  to  matters 
explicitly  discussed  therein)  does  not  describe  the  U.S. 
federal  income  tax  consequences  that  may  be  relevant  to 
certain  types  of  shareholders,  such  as  banks,  insurance 
companies,  and  other 
regulated 
financial 
investment companies, real estate investment trusts, financial 
asset  securitization  investment  trusts,  brokers,  dealers  or 
traders  in  securities,  entities  or  arrangements  classified  as 
partnerships or pass-through entities for U.S. federal income 
tax purposes or holders of equity interests therein, tax exempt 
entities,  “individual  retirement  accounts”  or  “Roth  IRAs”, 
expatriates  and  former  citizens  or  long-term  residents  of  the 
United  States,  persons  whose  functional  currency  for  U.S. 
federal  income  tax  purposes  is  not  the  U.S.  dollar,  persons 
that  own,  directly,  indirectly  or  constructively,  ten  percent 
(10%) or more of the total voting power or value of all of our 
outstanding  shares,  persons  owning  our  common  shares  or 
preferred  shares  in  connection  with  a  trade  or  business 
conducted  outside  the  United  States,  U.S.  holders  that  hold 
our  common  shares  or  preferred  shares  through  a  non-U.S. 
broker or other non-U.S. intermediary, persons who hold our 
common  shares  or  preferred  shares  as  part  of  a  hedging  or 
conversion  transaction  or  as  part  of  a  straddle  or  wash  sale, 
who  may  be  subject  to  special  rules  or  treatment  under  the 
Code  or  persons  required  for  U.S.  federal  income  tax 
purposed  to  recognize  income  no  later  than  such  income  is 
reported  on  such  persons’  applicable  financial  statements, 
and  persons  subject  to  the  alternative  minimum  tax.  This 
discussion is based upon the Code, the Treasury Regulations 
promulgated  there  under  and  any  relevant  administrative 
rulings  or  pronouncements  or  judicial  decisions,  all  as  in 
effect  on  the  date  of  this  annual  report  and  as  currently

If an entity that is treated as a partnership holds our common 
shares or preferred shares, the tax treatment of a partner will 
generally  depend  upon  the  status  of  the  partner  and  the 
activities of the partnership. If you are a partnership holding 
or  considering  an  investment  in  our  common  shares  or 
preferred shares or a partner therein, you should consult your 
tax advisor.

For  purposes  of  this  discussion,  the  term  “U.S.  Person” 
means a person that is, for U.S. federal income tax purposes:

•

•

•

•

an individual who is a citizen or resident of the U.S.; 

a corporation created or organized under the laws of the 
U.S., any state thereof or the District of Columbia; 

an estate, the income of which is subject to U.S. federal 
income taxation regardless of its source; or 

a  trust,  if  either  (i)  a  court  within  the  U.S.  is  able  to 
exercise  primary  supervision  over  the  administration  of 
such  trust  and  one  or  more  U.S.  persons  have  the 
authority to control all substantial decisions of such trust 
or (ii) the trust has a valid election in effect to be treated 
as a U.S. person for U.S. federal income tax purposes.

United  States—Taxation  of  Dividends.  The  preferred  shares 
should  be  properly  classified  as  equity  rather  than  debt  for 
U.S. federal income tax purposes. Subject to the discussions 
below  relating  to  the  potential  application  of  the  controlled 
foreign  corporation  (“CFC”),  “related  person  insurance 
income”  (“RPII”)  and  passive  foreign  investment  company 
(“PFIC”)  rules,  as  defined  below,  cash  distributions,  if  any, 
made with respect to our common shares or preferred shares 
will  constitute  dividends  for  U.S.  federal  income  tax 
purposes to the extent paid out of our current or accumulated 
earnings and profits (as computed using U.S. tax principles). 
If a U.S. holder of our common shares or our preferred shares 
is  an  individual  or  other  non-corporate  holder,  dividends 
paid,  if  any,  to  that  holder  that  constitute  qualified  dividend 
income  generally  will  be  taxable  at  the  rate  applicable  for 
long-term capital gains (generally up to 20%), provided that 
such  person  meets  a  holding  period  requirement.  Generally, 
in  order  to  meet  the  holding  period  requirement,  the  U.S. 
holder must hold the common shares for more than 60 days 
during  the  121-day  period  beginning  60  days  before  the  ex-
dividend  date  and  must  hold  preferred  shares  for  more  than 
90 days during the 181-day period beginning 90 days before 
the ex-dividend date. Dividends paid, if any, with respect to 
common shares or preferred shares generally will be qualified 
dividend  income,  provided  the  common  shares  or  preferred 
shares are readily tradable on an established securities market 
in the U.S. in the year in which the shareholder receives the 
dividend (which should be the case for shares that are listed 
on  the  Nasdaq  Stock  Market  or  the  New  York  Stock 
Exchange) and Arch Capital is not considered to be a passive 
foreign  investment  company  in  either  the  year  of  the 
distribution  or  the  preceding  taxable  year.  No  assurance  can 
be given that the preferred shares will be considered readily 

tradable  on  an  established  securities  market  in  the  U.S.  See 
“—Taxation of Our U.S. Shareholders” below.

A U.S. holder that is an individual, estate or a trust that does 
not fall into a special class of trusts that is exempt from such 
tax, will be subject to a 3.8% tax on the lesser of (1) the U.S. 
holder’s  “net  investment  income”  for  the  relevant  taxable 
year and (2) the excess of the U.S. holder’s modified adjusted 
gross  income  for  the  taxable  year  over  a  certain  threshold 
(which  in  the  case  of  individual  will  be  between  $125,000 
and $250,000, depending on the individual’s circumstances). 
A U.S. holder’s net investment income generally will include 
its dividend income and its net gains from the disposition of 
our  common  shares  and  preferred  shares,  unless  such 
dividend  income  or  net  gains  are  derived  in  the  ordinary 
course  of  the  conduct  of  a  trade  or  business  (other  than  a 
trade  or  business  that  consists  of  certain  passive  or  trading 
activities).

Distributions  with  respect  to  the  common  shares  and  the 
preferred  shares  will  not  be  eligible  for  the  dividends 
received  deduction  allowed  to  U.S.  corporations  under  the 
Code. To the extent distributions on our common shares and 
preferred shares exceed our earnings and profits, they will be 
treated  first  as  a  return  of  the  U.S.  holder's  basis  in  our 
common shares and our preferred shares to the extent thereof, 
and then as gain from the sale of a capital asset.

United States—Sale, Exchange or Other Disposition. Subject 
to the discussions below relating to the potential application 
of  the  CFC,  RPII  and  PFIC  rules,  U.S  holders  of  common 
shares  and  preferred  shares  generally  will  recognize  capital 
gain or loss, if any, for U.S. federal income tax purposes on 
the  sale,  exchange  or  other  taxable  disposition  of  common 
shares  or  preferred  shares,  as  applicable  in  an  amount  equal 
to  the  difference  between  the  amount  realized  on  the  sale, 
exchange  or  other  taxable  disposition  and  the  U.S  holder’s 
adjusted  tax  basis  in  the  shares.  Such  gain  or  loss  generally 
will  be  long  term  capital  gain  or  loss  if  the  U.S.  holder’s 
holding  period  for  the  shares  exceeds  one  year.  Long-term 
capital gains of certain non-corporate U.S. holders (including 
individuals)  are  generally  eligible  for  reduced  rates  of 
taxation.  The  deductibility  of  capital  losses  is  subject  to 
limitations.

United  States—Redemption  of  Preferred  Shares.  A 
redemption  of  the  preferred  shares  will  be  treated  under 
Section 302 of the Code as a dividend to the extent we have 
earnings  and  profits  allocable  to  such  shares,  unless  the 
redemption  satisfies  one  of  the  tests  set  forth  in  Section 
302(b) of the Code enabling the redemption to be treated as a 
sale or exchange, subject to the discussion herein relating to 
the  potential  application  of  the  CFC,  RPII  and  PFIC  rules. 
Under the relevant Code Section 302(b) tests, the redemption 
should  be  treated  as  a  sale  or  exchange  only  if  it  (1)  is 
substantially  disproportionate,  (2)  constitutes  a  complete

essentially equivalent to a dividend.” In determining whether 
any of these tests are met, shares considered to be owned by 
the  holder  by  reason  of  certain  constructive  ownership  rules 
set forth in the Code, as well as shares actually owned, must 
generally be taken into account. It may be more difficult for a 
U.S.  holder  who  owns,  actually  or  constructively  by 
operation  of  the  attribution  rules,  any  of  our  other  shares  to 
satisfy any of the above requirements.

actually  and  constructively  owned  by  the  U.S.  holder

termination  of  a  U.S.  holder’s  interest  if  either  (i)  all  of  our 
shares actually and constructively owned by the U.S. holder 
are  redeemed  or  (ii)  all  of  our  shares  actually  owned  by  the 
U.S.  holder  are  redeemed  and  the  U.S.  holder  is  eligible  to 
waive,  and  effectively  waives  in  accordance  with  specific 
rules,  the  attribution  of  shares  owned  by  certain  family 
members  and  the  U.S.  holder  does  not  constructively  own 
any  other  of  our  shares.  The  redemption  of  our  shares  will 
not be essentially equivalent to a dividend if such redemption 
results  in  a  “meaningful  reduction”  of  the  U.S.  holder’s 
proportionate  interest  in  us.  Whether  the  redemption  will 
result 
in  a  U.S.  holder’s 
proportionate interest in us will depend on the particular facts 
and  circumstances.  However,  the  IRS  has  indicated  in  a 
published  ruling 
the 
proportionate  interest  of  a  small  minority  shareholder  in  a 
publicly  held  corporation  who  exercises  no  control  over 
corporate  affairs  may  constitute  such  a  “meaningful 
reduction.”  The  determination  as  to  whether  any  of  the 
alternative  tests  of  Section  302(b)  of  the  Code  is  satisfied

If  none  of  the  foregoing  tests  are  satisfied,  then  the 
redemption  of  any  of  our  shares  will  be  treated  as  a

United  States—Taxation  of  Dividends”  above.  After  the 
application of those rules, any remaining tax basis of the U.S. 
holder  in  the  redeemed  shares  will  be  added  to  the  U.S. 
holder’s  adjusted  tax  basis  in  its  remaining  shares,  or, 
possibly,  in  other  shares  constructively  owned  by  it.  A  U.S.

Taxation of Our U.S. Shareholders

Controlled  Foreign  Corporation  Rules.  We  or  any  of  our 
non-U.S. subsidiaries generally will be treated as a CFC with 
respect to any taxable year if at any time during such taxable 
year,  one  or  more  “10%  U.S.  Shareholders”  (as  defined 
below)  collectively  own  more  than  50%  of  us  or  such  non-
U.S.  subsidiary  (as  applicable)  by  vote  or  value  (taking  into 
account shares actually owned by such U.S. holder as well as 
shares  attributed  to  such  U.S.  holder  under  the  Code  or  the 
Treasury Regulations thereunder). Moreover, with respect to 
insurance income (including reinsurance income), the “more 
than 50%” requirement described in the preceding sentence is 
replaced  with  a  more  expansive  “more 
than  25%” 
requirement. A 10% U.S. Shareholder means any U.S. Person 
who was considered to own, actually or constructively, 10% 
or  more  of  the  total  combined  voting  power  or  total 
combined  value  of  our  shares  or  those  of  our  non-U.S. 
subsidiaries (as applicable). As a result of a change in law for 
taxable years beginning after December 31, 2017, the voting 
cut-back  limitation  contained  in  our  bye-laws  that  limits  the 
votes  conferred  by  the  Controlled  Shares  (as  defined  in  our 
bye-laws)  of  any  U.S.  Person  to  9.9%  of  the  total  voting 
power of all our shares entitled to vote will not prevent any 
U.S.  holder  from  being  treated  as  a  10%  U.S.  Shareholder. 
Due to the repeal of Section 958(b)(4) of the Code under the 
Tax Cuts Act, all non-U.S. subsidiaries directly or indirectly 
owned  by  Arch  Capital  are  treated  as  constructively  owned 
by its U.S. subsidiaries, and therefore are treated as CFCs.

Status as a CFC would not cause us or any of our non-U.S. 
subsidiaries  to  be  subject  to  U.S.  federal  income  tax.  Such 
status  also  would  have  no  adverse  U.S.  federal  income  tax 
consequences  for  any  U.S.  holder  that  is  not  a  10%  U.S. 
Shareholder  with  respect  to  us  or  any  such  non-U.S. 
subsidiary  (as  applicable).  If  we  or  any  of  our  non-U.S. 
subsidiaries  are  or  were  a  CFC  with  respect  to  any  taxable 
year, a U.S. holder that is considered a 10% U.S. Shareholder 
would be subject to current U.S. federal income taxation (at 
ordinary income tax rates) to the extent of all or a portion of 
the undistributed earnings and profits of Arch Capital and our 
subsidiaries  attributable  to  “subpart  F  income”  (including 
certain  insurance  premium  income  and  investment  income) 
or global intangible low-taxed income and may be taxable at 
ordinary income tax rates on any gain recognized on a sale or 
other  disposition  (including  by  way  of  repurchase  or 
liquidation) of our common shares or preferred shares to the 
extent  of  the  current  and  accumulated  earnings  and  profits 
attributable to such common shares or preferred shares.

significant respects. First, in determining CFC status, as well 
as determining which U.S. shareholders are subject to current 
taxation  with  respect  to  a  CFC’s  RPII  (whether  or  not 
currently  distributed),  all  U.S.  shareholders  (as  opposed  to 
only 10% U.S. Shareholders) are taken into account. Second, 
the  amount  of  stock  in  a  foreign  corporation  that  all  U.S. 
shareholders, in the aggregate, must own for such corporation 
to  be  treated  as  a  CFC  is  reduced  from  more  than  50%  (by 
vote  or  value),  and  more  than  25%  (by  vote  or  value)  with 
respect  to  insurance  income  generally,  to  25%  or  more  (by

is 

Under  one  exception  to  the  foregoing  RPII  rules,  U.S. 
shareholders  are  not  required  to  include  a  CFC’s  RPII 
currently in income if the CFC’s gross RPII is less than 20% 
of  its  total  gross  insurance  income  for  the  taxable  year  in 
question (the “RPII 20% gross income exception”). 

Under current law, we currently expect each of our non-U.S. 
subsidiaries to satisfy the RPII 20% gross income exception, 
and 
therefore  we  currently  do  not  expect  any  U.S. 
shareholder  to  be  required  to  include  RPII  in  income 
(although  there  can  be  no  assurance  that  this  is  or  will 
continue  be 
the  case).  However,  proposed  Treasury 
Regulations  issued  on  January  24,  2022,  if  finalized  in  their 
current form, would for the first time (on a prospective basis) 
expand the definition of RPII to include certain intercompany 
insurance income (including reinsurance income) in a manner 
that  could  cause  certain  of  our  foreign  subsidiaries  not  to 
satisfy the RPII 20% gross income exception. In such event, 
(1) as noted above, all U.S. shareholders (not just 10% U.S. 
Shareholders)  would  be  required  to  include  RPII  in  income 
currently, whether or not distributed, and (2) as noted below, 
U.S.  shareholders  that  are  tax  exempt  entities  would  be 
required  to  treat  such  RPII  inclusions  as  unrelated  business 
taxable income. Current and prospective U.S. holders should 
consult  their  own  tax  advisors  as  to  the  potential  impact  of 
these proposed Treasury Regulations.

Section 953(c)(7) of the Code generally provides that Section 
1248  of  the  Code  (which  generally  would  require  a  U.S. 
holder to treat certain gains attributable to the sale, exchange 
or  disposition  of  common  shares  or  preferred  shares  as  a 
dividend)  will  apply  to  the  sale  or  exchange  by  a  U.S. 
shareholder  of  shares  in  a  foreign  corporation  that  is 
characterized  as  a  CFC  under  the  RPII  rules  if  the  foreign 
corporation  would  be  taxed  as  an  insurance  company  if  it 
were  a  U.S.  corporation,  regardless  of  whether  the  U.S. 
shareholder  is  a  10%  U.S.  Shareholder  or  whether  the 
corporation  qualifies  for  the  RPII  20%  gross  income 
exception.  Although  existing  Treasury  Regulations  do  not 

address  the  question,  proposed  Treasury  Regulations  issued 
in  April  1991  create  some  ambiguity  as  to  whether  Section 
1248  and  the  requirement  to  file  Form  5471  would  apply 
when  the  non-U.S.  corporation  has  a  foreign  insurance 
subsidiary that is a CFC for RPII purposes and that would be 
taxed  as  an  insurance  company  if  it  were  a  domestic 
corporation.  We  believe 
the 
requirement  to  file  Form  5471  will  not  apply  to  a  less  than 
10%  U.S.  Shareholder  because  Arch  Capital  is  not  directly 
engaged  in  the  insurance  business.  There  can  be  no 
assurance,  however,  that  the  IRS  will  interpret  the  proposed 
Treasury Regulations in this manner or that the Treasury will 
not take the position that Section 1248 and the requirement to 
file  Form  5471  will  apply  to  dispositions  of  our  common 
shares or our preferred shares.

that  Section  1248  and 

If the IRS or U.S. Treasury were to make Section 1248 of the 
Code and the Form 5471 filing requirement applicable to the 
sale of our shares, we would notify shareholders that Section 
1248 of the Code and the requirement to file Form 5471 will 
apply  to  dispositions  of  our  shares.  Thereafter,  we  would 
send  a  notice  after  the  end  of  each  calendar  year  to  all 
persons  who  were  shareholders  during  the  year  notifying 
them  that  Section  1248  of  the  Code  and  the  requirement  to 
file  Form  5471  apply  to  dispositions  of  our  shares  by  U.S. 
holders. We would attach to this notice a copy of Form 5471 
completed  with  all  our  information  and  instructions  for 
completing the shareholder information.

Tax-Exempt  Shareholders.  Tax-exempt  entities  may  be 
required  to  treat  certain  Subpart  F  insurance  income, 
including RPII, that is includible in income by the tax-exempt 
entity  as  unrelated  business  taxable  income.  Current  and 
prospective  U.S.  holders  that  are  tax  exempt  entities  should 
consult  their  own  tax  advisors  as  to  the  potential  impact  of 
the unrelated business taxable income provisions of the Code.

Passive  Foreign  Investment  Companies.  Sections  1291 
through  1298  of  the  Code  contain  special  rules  applicable 
with  respect  to  foreign  corporations  that  are  PFICs.  In 
general, a foreign corporation will be a PFIC if 75% or more 
of its income constitutes “passive income” or 50% or more of 
its  assets  produce  passive  income.  If  we  were  to  be 
characterized  as  a  PFIC,  U.S.  holders  would  be  subject  to  a 
penalty  tax  at  the  time  of  their  sale  of  (or  receipt  of  an 
“excess distribution” with respect to) their common shares or 
preferred shares imposed at the highest applicable rate under 
the Code for the applicable tax year. In general, a shareholder 
receives  an  “excess  distribution”  if  the  amount  of  the 
distribution  is  more  than  125%  of  the  average  distribution 
with respect to the shares during the three preceding taxable 
years  (or  shorter  period  during  which  the  taxpayer  held  the 
stock). In general, the penalty tax is equivalent to an interest 
charge  on  taxes  that  are  deemed  due  during  the  period  the 
shareholder owned the shares, computed by assuming that the 
excess distribution or gain (in the case of a sale) with respect 

ARCH CAPITAL

38

2023 FORM 10-K

to  the  shares  was  taxable  in  equal  portions  throughout  the 
holder’s period of ownership. The interest charge is equal to 
the applicable rate imposed on underpayments of U.S. federal 
income  tax  for  such  period.  A  U.S.  shareholder  may  avoid 
some of the adverse tax consequences of owning shares in a 
PFIC by making a qualified electing fund (“QEF”) election. 
A QEF election is revocable only with the consent of the IRS 
and has the following consequences to a shareholder:

•

•

For  any  year  in  which  Arch  Capital  is  a  PFIC,  the 
shareholder  would  include  in  its  taxable  income  a 
proportionate  share  of  the  net  ordinary  income  and  net 
capital gains of Arch Capital and certain of its non-U.S. 
subsidiaries.

For  any  year  in  which  Arch  Capital  is  not  a  PFIC,  the 
shareholder  would  not  be  subject  to  the  QEF  inclusion 
regime  described  in  the  preceding  paragraph  for  such 
taxable year.

For taxable years beginning on or before December 31, 2017, 
the  determination  of  whether  the  active  insurance  company 
exception  applies  to  an  insurance  company  was  made  on  a 
case-by-case basis and the analysis was inherently subjective. 
Under  the  Tax  Cuts  Act,  for  taxable  years  beginning  after 
December 31, 2017, the active insurance company exception 
applies  only  if  (i)  the  company  would  be  taxed  as  an 
insurance company were it a U.S. corporation and (ii) either 
(A)  loss  and  loss  adjustment  expense  and  certain  reserves 
constitute  more  than  25%  of  the  company’s  gross  assets  for 
the  relevant  year  or  (B)  loss  and  loss  adjustment  expenses 
and  certain  reserves  constitute  more  than  10%  of  the 
company’s  gross  assets  for  the  relevant  year  and,  based  on 
the  applicable  facts  and  circumstances,  the  company  is 
predominantly  engaged  in  an  insurance  business  and  the 
failure  of  the  company  to  satisfy  the  preceding  25%  test  is 
due solely to run-off related or other specified circumstances 
involving 
insurance  business.  The  PFIC  statutory 
provisions  contain  a  look-through  rule  that  states  that,  for 
purposes  of  determining  whether  a  foreign  corporation  is  a 
PFIC,  such  foreign  corporation  shall  be  treated  as  if  it 
“received directly its proportionate share of the income” and 
as if it “held its proportionate share of the assets” of any other 
corporation  in  which  it  owns  at  least  25%  of  the  stock.  We 
believe that we were not a PFIC for any taxable year ended 
on  or  before  December  31,  2023,  and  we  currently  are  not 
expecting to become a PFIC for any subsequent taxable year. 
However, due to the complexity and uncertainty of the PFIC 
rules and the limited guidance interpreting them, there can be 
no assurance that we have not been a PFIC to date or that we 
will  not  become  a  PFIC  at  some  time  in  the  future.  In 
addition, our U.S. counsel expresses no opinion with respect 
to our PFIC status for our current or future taxable years.

application  of  the  insurance  company  exception.  While  we 
believe that the 2020 final PFIC insurance regulations and the 
2020  proposed  PFIC  insurance  regulations  should  not 
adversely impact our ability to satisfy the insurance company 
exception and avoid being treated as a PFIC, there can be no 
assurance  that  such  exception  will  in  fact  apply  and/or  will 
continue to apply at all times in the future. Each U.S. holder 
should  consult  its  own  tax  advisor  as  to  the  effects  of  these 
rules.

Backup Withholding and Information Reporting. Payments of 
dividends and sales proceeds from a sale, exchange or other 
taxable  disposition  (including  redemption)  of  our  common 
shares  or  preferred  shares  that  are  made  within  the  United 
States,  by  a  U.S.  payor  or  through  certain  U.S.-related 
financial intermediaries to a U.S. holder generally are subject 
to  information  reporting,  unless  the  U.S.  holder  is  a 
corporation  or  other  exempt  recipient,  and  if  required, 
demonstrates  that  fact.  In  addition,  such  payments  may  be 
subject to backup withholding, unless (1) the U.S. holder is a 
corporation  or  other  exempt  recipient  or  (2)  the  U.S.  holder 
provides  a  correct  taxpayer  identification  number  and 
certifies  that  it  is  not  subject  to  backup  withholding  in  the 
manner  required.  Backup  withholding  is  not  an  additional 
tax. The amount of any backup withholding from a payment 
to a U.S. holder will generally be allowed as a credit against 
the  U.S.  holder’s  U.S.  federal  income  tax  liability  or  may 
entitle the U.S. holder to a refund, provided that the required 
information is timely furnished to the IRS.

Foreign Financial Asset Reporting. Certain U.S. persons are 
required  to  report  information  relating  to  interests  in 
“specified  foreign  financial  assets”,  including  shares  issued 
by  a  non-U.S.  corporation,  for  any  year  in  which  the 
aggregate  value  of  all  specified  foreign  financial  assets 
exceeds  certain  thresholds,  subject  to  certain  exceptions 
(including an exception for shares held in a custodial account 
maintained  with  a  U.S.  financial  institution).  Penalties  may 
be  imposed  for  a  failure  to  disclose  such  information.  U.S. 
holders  are  urged  to  consult  their  tax  advisers  regarding  the 
effect,  if  any,  of  these  additional  reporting  requirements  on 
their  ownership  and  disposition  of  our  common  shares  or 
preferred shares.

United States Taxation of Non-U.S. Shareholders

Taxation of Dividends. Cash distributions, if any, made with 
respect  to  common  shares  or  preferred  shares  held  by  a 
holder  that  is,  for  U.S.  federal  income  tax  purposes,  an 
individual,  corporation,  estate  or  trust  that  is  not  a  U.S. 
holder (a “Non-U.S. holder”) generally will not be subject to 
U.S. withholding tax (subject to certain exceptions that may 
apply  if  we  were  determined  to  be  engaged  in  a  trade  or 
business in the United States and 25% or more of our gross

income were to be effectively connected to such U.S. trade or 
business).

Sale,  Exchange  or  Other  Disposition.  Non-U.S.  holders  of 
common  shares  or  preferred  shares  generally  will  not  be 
subject  to  U.S.  federal  income  tax  with  respect  to  gain 
recognized  upon  the  sale,  exchange  or  other  disposition  of 
such  shares  unless  such  gain  is  effectively  connected  with  a 
U.S. trade or business of the Non-U.S. holder or such person 
is present in the U.S. for 183 days or more in the taxable year 
the  gain  is  recognized  and  certain  other  requirements  are 
satisfied.

Information  Reporting  and  Backup  Withholding.  Non-U.S. 
holders  of  common  shares  or  preferred  shares  will  not  be 
subject to U.S. information reporting or backup withholding 
with  respect  to  dispositions  of  common  or  preferred  shares 
effected  through  a  non-U.S.  office  of  a  broker,  unless  the 
broker has certain connections to the U.S. or is a U.S. person. 
No  U.S.  backup  withholding  will  apply  to  payments  of 
dividends,  if  any,  on  our  common  shares  or  our  preferred 
shares.

FATCA  Withholding.  Sections  1471  through  1474  to  the 
Code,  known  as  the  Foreign  Account  Tax  Compliance  Act 
(“FATCA”),  impose  a  withholding  tax  of  30%  on  U.S.-
source interest, dividends and certain other types of income, 
which  is  received  by  a  foreign  financial  institution  (“FFI”), 
unless  such  FFI  enters  into  an  agreement  with  the  IRS  to 
obtain certain information as to the identity of the direct and 
indirect owners of accounts in such institution. In addition, a 
30% withholding tax may be imposed on the above payments 
to  certain  non-financial  foreign  entities  which  do  not  (i) 
certify to each applicable withholding agent that they have no 
“substantial U.S. owners” (i.e., a U.S. 10% direct or indirect 
shareholder), or (ii) provide such withholding agent with the 
certain information as to the identity of such substantial U.S. 
owners.  The  U.S.  has  entered 
intergovernmental 
agreements to implement FATCA (“IGAs”) with a number of 
jurisdictions.  Bermuda  has  signed  an  IGA  with  the  U.S. 
Different  rules  than  those  described  above  may  apply  under 
such an IGA.

into 

Although  dividends  with  respect  to  our  common  shares  or 
preferred  shares  generally  will  be  treated  as  foreign  source 
for  U.S.  federal  withholding  tax  purposes,  it  is  unclear 
whether, for FATCA purposes, some or all of our dividends 
may  be  recharacterized  as  U.S.  source  dividends.  Treasury 
Regulations addressing this topic have not yet been issued.

Current  and  prospective  investors  should  consult  their  own 
tax advisors as to the filing and information requirements that 
may be imposed on them in respect of their ownership of our 
common share or preferred shares.

Other  Tax  Laws.  Shareholders  should  consult  their  own  tax 
advisors  with  respect  to  the  applicability  to  them  of  the  tax 
laws of other jurisdictions.

RISK FACTORS SUMMARY

The following is a summary description of the material risks 
and uncertainties to which we may be exposed. Each of these 
risks could adversely affect our business, financial condition 
and  results  of  operations,  and  any  such  effects  may  be 
material. These and other risks are more fully described after 
this summary description.

Risks Relating to Our Industry, Business and Operations

• We operate in a highly competitive environment. 

• The  insurance  and  reinsurance  industry  is  highly  cyclical, 
and  we  may  at  times  experience  periods  characterized  by 
excess  underwriting  capacity  and  unfavorable  premium 
rates.

• The effects of inflation and global recessionary conditions 
impact  the  insurance  and  reinsurance  industry  in  ways 
which  may  negatively  impact  our  business,  financial 
condition and results of operations.

• Claims for natural and man-made catastrophic events could 
cause large losses and substantial volatility in our results of 
operations and could have a material adverse effect on our 
financial position and results of operations.

• The impact of climate change will affect our loss limitation 
methods,  such  as  the  purchase  of  third  party  reinsurance 
and  catastrophe  risk  modeling  and  risk  selection  in  ways 
which  may  adversely  impact  our  business,  financial 
condition and results of operations.

• Our  insurance  and  reinsurance  subsidiaries  are  subject  to 
supervision and regulation. Changes to existing regulation 
and  supervisory  standards,  or  failure  to  comply  with 
applicable 
requirements,  could  adversely  affect  our 
business and results of operations.

• The  Russian  invasion  of  Ukraine  and  the  resulting 
imposition  of  sanctions  by  the  U.S.,  U.K.  and  EU  on 
Russia  and  Russia-related  businesses  created  global 
instability.

• Our customers and policyholders may also be impacted by 
regulatory,  technological,  market  or  other  risks  relating  to 
climate  change  in  ways  which  we  cannot  predict  with 
certainty and adversely impact our results of operations.

shareholders, 

• As  we  continue  to  incorporate  climate  change  and  other 
ESG factors in our business strategy, we cannot be certain 
that 
influential 
environmental  and  social-focused  groups  will  agree  with 
our  approach,  which  may  adversely  impact  our  ability  to 
raise funds in the capital markets, our share price and our 
results of operations.

• We  could  face  unanticipated 

increased 
geopolitical  tensions,  hostilities,  war,  terrorism,  cyber 
attacks and general political instability, and these or other 
unanticipated  losses  could  have  a  material  adverse  effect 
on our financial condition and results of operations.

losses  from 

• Underwriting  risks  and  reserving  for  losses  are  based  on 
probabilities  and  related  modeling,  which  are  subject  to 
inherent uncertainties.

• The  failure  of  any  of  the  loss  limitation  methods  we 
employ  could  have  a  material  adverse  effect  on  our 
financial condition or results of operations.

• The availability of reinsurance, retrocessional coverage and 
capital  market  transactions  to  limit  our  exposure  to  risks 
may  be  limited,  and  counterparty  credit  and  other  risks 
associated with our reinsurance arrangements may result in 
losses which could adversely affect our financial condition 
and results of operations.

• We could be materially adversely affected to the extent that 
important  third  parties  with  whom  we  do  business  do  not 
adequately  or  appropriately  manage  their  risks,  commit 
fraud or otherwise breach obligations owed to us.

• Emerging claim and coverage issues may adversely affect 

our business. 

• Acquisitions,  the  addition  of  new  lines  of  insurance  or 
reinsurance  business,  expansion  into  new  geographic 
regions  and/or  entering  into  joint  ventures  or  partnerships 
expose us to risks.

• Our  information  technology  systems  may  be  unable  to 

meet the demands of customers and our workforce.

• Technology  failures  and  cyber  attacks,  including,  but  not 
limited  to,  ransomware,  exploitation  in  software  or  code 
with  malicious  intent,  state-sponsored  cyber  attacks,  as 
well as vulnerabilities relating to new technologies, such as 
generative AI, may impact us or our business partners and 
service  providers,  causing  a  disruption  in  service  and 
operations  which  could  materially  and  negatively  impact 
our business and/or expose us to litigation. 

• Cyber  incidents  or  data  breaches  caused  by  bad  actors  or 
unintentional  human  error 
including 
personal  data,  we  maintain  or  use  during  our  business 
operations  may  result  in  regulatory  fines  or  action, 
reputation  damage  and  a  disruption  in  our  business 
operations.

impacting  data, 

• Changes  in  criteria  used  by  rating  agencies  which  may 
result in a downgrade in our ratings, our inability to obtain 
a  rating  or  a  change  in  capital  allocation  or  requirements 
for  our  operating  insurance  and  reinsurance  subsidiaries 
may  adversely  affect  our  relationships  with  clients  and 
brokers and negatively impact sales of our products.

• Our  ability  to  execute  our  business  strategy  successfully, 
continue  to  grow  and  innovate  and  offer  our  employees  a 
dynamic  and  supportive  workplace  depends  on 
the 
recruitment,  retention  and  promotion  of  talented,  agile, 
diverse  and  resilient  employees  at  all  levels  of  our 
organization.

• Our  success  will  depend  on  our  ability  to  maintain  and 
internal 

enhance  effective  operating  procedures  and 
controls and our ERM program.

• We  are  exposed  to  credit  risk  in  certain  of  our  business 

operations.

• Our  business  is  subject  to  applicable  laws  and  regulations 
relating  to  economic  trade  sanctions  and  foreign  bribery 
laws,  the  violation  of  which  could  adversely  affect  our 
operations.

• New  legislation  or  regulations  relating  to  the  U.K.’s 

withdrawal from the EU could adversely affect us.

Risks Relating to Financial Markets and Investments

• Adverse developments in the financial markets could have 
a  material  adverse  effect  on  our  results  of  operations, 
financial  position  and  our  businesses,  and  may  also  limit 
our  access  to  capital;  our  policyholders,  reinsurers  and 
retrocessionaires  may  also  be  affected  by 
such 
developments, which could adversely affect their ability to 
meet their obligations to us.

• Disruption  to  the  financial  markets  and  weak  economic 
conditions resulting from situations such as post pandemic 
inflation  and  geopolitical  conflict  may

adversely and materially impact our investments, financial 
condition and results of operation.

• Foreign currency exchange rate fluctuation may adversely 

affect our financial results.

• The determination of the amount of current expected credit 
losses  (“CECL”)  allowances  taken  on  our  investments  is 
highly subjective and could materially impact our results of 
operations or financial position.

• Our  reinsurance  subsidiaries  may  be  required  to  provide 
collateral  to  ceding  companies,  by  applicable  regulators, 
their  contracts  or  other  commercial  considerations.  Their 
ability  to  conduct  business  could  be  significantly  and 
negatively affected if they are unable to do so. 

Risks Relating to Our Mortgage Operations

• The  ultimate  performance  of  our  mortgage  insurance 

portfolios remains uncertain.

• If the volume of low down payment mortgage originations 
declines, or if other government housing policies, practices 
or  regulations  change,  the  amount  of  mortgage  insurance 
we write in the U.S. could decline, which would reduce our 
mortgage insurance revenues.

• Changes to the role of the GSEs in the U.S. housing market 
or to GSE eligibility requirements for mortgage insurers or 
to  the  GSEs’  use  of  CRT  could  negatively  impact  our 
results of operations and financial condition or reduce our 
operating flexibility.

• The  implementation  of  the  Basel  III  Capital  Accord  and 
FHFA’s  Enterprise  Regulator  Capital  Framework  may 
adversely  affect  the  use  of  mortgage  insurance  and  CRT 
opportunities.

Risk Relating to Our Company

• Some  of 

the  provisions  of  our  bye-laws  and  our 
shareholders  agreement  may  have  the  effect  of  hindering, 
delaying or preventing third party takeovers or changes in

Risks Relating to Our Industry, Business and Operations

We operate in a highly competitive environment, and we may 
not be able to compete successfully in our industry.

The insurance and reinsurance industry is highly competitive. 
We  compete  on  an  international  and  regional  basis  with 
major  U.S.  and  non-U.S.  insurers  and  reinsurers,  many  of 
which  have  greater  financial,  marketing  and  management 
resources than we do. See “Competition” in Item 1 for details 
on our competitors in each of the major segments we operate 
in. There has been significant consolidation in the insurance 
and reinsurance sector in recent years and we may experience 
increased  competition  as  a  result  of  that  consolidation,  with 
consolidated  entities  having  enhanced  market  power.  These 
consolidated  entities  may  use  their  enhanced  market  power 
and  broader  capital  base  to  negotiate  price  reductions  for 
products  and  services  that  compete  with  ours,  and  we  may 
experience rate declines and possibly write less business. We 
also  compete  on  the  basis  of  product  offerings  and  other 
factors,  such  as  our  approach  to  ESG  and  our  use  of 
technologies,  and  customers  may  be  drawn 
to  our 
competitors  based  on  these  factors.  Any  failure  by  us  to 
effectively  compete  could  adversely  affect  our  financial 
condition and results of operations.

Historically,

significant 
competition, 
frequency  of  occurrence  or  severity  of 
catastrophic  events,  levels  of  capacity,  general  economic 
conditions,  inflation,  changes  in  equity,  debt  and  other 
investment  markets,  changes  in  legislation,  case  law  and 
prevailing concepts of liability and other factors. Demand for 
reinsurance  is  influenced  significantly  by  the  underwriting 
results  of  primary  insurers  and  prevailing  general  economic 
conditions. The supply of insurance and reinsurance is related 
to  prevailing  prices  and  levels  of  surplus  capacity  that,  in 
turn,  may  fluctuate  in  response  to  changes  in  rates  of  return 
being  realized  in  the  insurance  and  reinsurance  industry  on 
both  underwriting  and  investment  sides.  As  a  result,  the 
insurance  and  reinsurance  business  historically  has  been  a 
cyclical  industry  characterized  by  periods  of  intense  price 
competition due to excessive underwriting capacity as well as 
periods  when  shortages  of  capacity  permitted  favorable 
premium  levels  and  changes  in  terms  and  conditions.  Until 
recently,  the  supply  of  insurance  and  reinsurance  had 
increased  over  the  past  several  years,  and  may  again  in  the 
future, either as a result of capital provided by new entrants 
or  by  the  commitment  of  additional  capital  by  existing 
insurers  or  reinsurers.  Continued  increases  in  the  supply  of 
insurance  and  reinsurance  may  have  consequences  for  us, 
including  fewer  contracts  written,  lower  premium  rates, 
increased  expenses  for  customer  acquisition  and  retention, 
and less favorable policy terms and conditions.

The  effects  of  inflation  and  global  recessionary  conditions 
impact the insurance and reinsurance industry in ways which 
may negatively impact our business, financial condition and 
results of operations.

While  general  economic  inflation  has  eased  in  recent 
quarters,  higher  inflationary  conditions  may  continue  to 
remain in place. The potential also exists, after a catastrophe 
loss  or  pandemic  events  like  COVID-19,  or  geopolitical 
tensions  and  hostilities  for  the  development  of  inflationary 
pressures  in  a  local  or  regional  economy.  This  may  have  a 
material effect on the adequacy of our reserves for losses and 
loss adjustment expenses, especially in longer-tailed lines of 
business.  In  addition,  governmental  actions  in  response  to 
inflationary  pressures,  such  as  increasing  interest  rates,  may 
have a material impact on the market value of our investment 
portfolio.  While  we  consider  the  anticipated  effects  of 
inflation  in  our  pricing  models,  reserving  processes  and 
exposure  management  across  all  lines  of  business  and  types 
of loss including natural catastrophe events, the actual effects 
of  inflation  on  our  results  cannot  be  accurately  known  until 
claims  are  settled.  In  addition,  there  are  different  types  of 

inflation  relevant  to  certain  lines  of  business,  the  impact  of 
which  is  difficult  to  accurately  assess  at  this  time.  For 
example,  in  our  mortgage  business,  the  failure  of  general 
wages  to  keep  pace  with  economic  inflation,  or  increases  in 
unemployment  due  to  prolonged  recessionary  conditions, 
could  prevent  borrowers  from  being  able  to  afford  their 
mortgage  payments  and  thereby  increase  the  frequency  of 
claims  beyond  our  modeled  results.  Global  recessionary 
conditions,  including  inflation,  the  slow  recovery  of  certain 
sectors  from  the  pandemic,  predicted  slow  growth  rates 
across  key  markets  and  other  factors,  will  impact  the 
insurance and reinsurance industry. There is great uncertainty 
around  how  severe  and  how  long  a  recession  will  last  on  a 
global  and  local  basis.  While  our  risk  management  and 
business  strategy  take  recessionary  conditions  into  account, 
we cannot accurately predict the full impact of a recession on 
our results of business operations.

Claims for natural and man-made catastrophic events could 
cause large losses and substantial volatility in our results of 
operations  and  could  have  a  material  adverse  effect  on  our 
financial position and results of operations.

We have large aggregate exposures to natural and man-made 
catastrophic  events.  Natural  catastrophes  can  be  caused  by 
various  events, 
including  hurricanes,  floods,  wildfires, 
tsunamis,  windstorms,  earthquakes,  hailstorms,  tornadoes, 
explosions,  severe  winter  weather,  fires,  droughts  and  other 
natural  disasters.  The  frequency  and  severity  of  natural 
catastrophe activity has also been greater in recent years due 
to climate change caused in part by human actions and other 
related  factors.  Catastrophic  events  caused  by  humans  may 
include acts of war, acts of terrorism and political instability. 
Catastrophes can cause losses in non-property business such 
as workers’ compensation or general liability. In addition to 
the nature of the property business, we believe that economic 
and  geographic  trends  affecting  insured  property,  including 
inflation,  property  value  appreciation  and  geographic 
concentration  tend  to  generally  increase  the  size  of  losses 
from catastrophic events over time. Actual losses from future 
catastrophic events have varied materially from estimates due 
to  the  inherent  uncertainties  in  making  such  determinations 
resulting  from  several  factors, 
the  potential 
inaccuracies and inadequacies in the data provided by clients, 
brokers and ceding companies, the modeling techniques and 
the  application  of  such  techniques,  the  contingent  nature  of 
business  interruption  exposures,  the  effects  of  any  resultant 
demand  surge  on  claims  activity  and  attendant  coverage 
issues. In estimating our losses from catastrophic events our 
considerations  can  include  factors  such  as  overall  market 
losses,  additional  claims  information  from  our  clients, 
multiple model views and proprietary scenario testing. All of 
the  catastrophe  modeling  tools  that  we  use  or  rely  on  to 
evaluate  our  catastrophe  exposures  are  therefore  based  on 
significant  assumptions  and  judgments  and  are  subject  to

could be materially different than our actual results.

transition  that  these  companies  make  towards  addressing 
climate risk in their own businesses. 

The  impact  of  climate  change  will  affect  our  loss  limitation 
methods, such as the purchase of third party reinsurance and 
catastrophe  risk  modeling  and  risk  selection  in  ways  which 
may  adversely  impact  our  business,  financial  condition  and 
results of operations.

Changing  weather  patterns  and  climatic  conditions,  such  as 
global warming, have added to the unpredictability, severity 
and  frequency  of  natural  disasters.  Uncertainty  about 
complexities  of  climate  change  affects  our  ability  to  assess 
with  certainty  the  full  impact  of  climate  change  and  creates 
uncertainty  about  future  trends  and  exposures.  Although  the 
loss  experience  of  catastrophe  insurers  and  reinsurers  has 
historically  been  characterized  as  low  frequency,  climate 
change  has  impacted  the  frequency  and  severity  of  extreme 
weather  events  and  natural  catastrophes  such  as  hurricanes, 
tornado  activity,  other  windstorms,  floods,  wildfires  and 
droughts in recent years and may continue to increase in the 
future. 

Claims  for  catastrophic  events,  or  an  unusual  frequency  of 
smaller losses in a particular period, could expose us to large 
losses, cause substantial volatility in our results of operations 
and  could  have  a  material  adverse  effect  on  our  ability  to 
write  new  business  if  we  are  not  able  to  adequately  assess 
and  reserve  for  the  increased  frequency  and  severity  of 
catastrophes  resulting  from  these  environmental  factors. 
Climate  change  and  increasing  catastrophic  events  could 
increase property damage to residential real estate secured by 
mortgages  owned  by  the  GSEs,  and  by  extension  could 
increase  losses  to  CRT  investors.  Increasing  catastrophic 
events could increase the cost of homeowners insurance and 
could  negatively  impact  mortgagees’  ability  to  meet  their 
monthly  housing  payment  obligations,  and  by  extension 
could increase the frequency of claims. Additionally, climate 
change may make modeled outcomes less certain or produce 
new,  non-modeled  risks.  Catastrophic  events  could  result  in

Changes in security asset prices may impact the value of our 
real  estate  and  commercial  mortgage 
fixed 
investments, resulting in realized or unrealized losses on our 
invested  assets.  These  risks  are  not  limited  to,  but  can 
include:  (i)  changes  in  supply/demand  characteristics  for 
fossil fuels (e.g., coal, oil, natural gas); (ii) advances in low-
carbon  technology  and  renewable  energy  development;  and 
(iii)  effects  of  extreme  weather  events  on  the  physical  and 
operational  exposure  of  industries  and  issuers,  and  the 

We attempt to manage our exposure to these risks relating to 
climate  change  through  the  use  of  underwriting  controls, 
proprietary  and  third  party  risk  models,  and  the  purchase  of 
third  party  reinsurance.  Underwriting  controls  can  include 
more 
restrictive  underwriting  criteria  such  as  higher 
premiums  and  deductibles,  reduction  in  limits  offered  or 
losses  retained,  and  more  specifically  excluded  policy  risks. 
Our  exposure  in  connection  with  a  catastrophic  event  is 
determined by market capacity, pricing conditions, regulatory 
capital  requirements,  our  perceptions  of  underlying  risk  and 
surplus  preservation.  There  can  be  no  assurance  that  our 
reinsurance  coverage  and  other  measures  taken  will  be 
sufficient  to  mitigate  losses  resulting  from  one  or  more 
catastrophic  events.  As  a  result,  the  occurrence  of  one  or 
more catastrophic events and the continuation and worsening 
of recent trends could have an adverse effect on our results of 
operations and financial condition.

Our  insurance  and  reinsurance  subsidiaries  are  subject  to 
supervision  and  regulation.  Changes  to  existing  regulation 
and  supervisory  standards,  or  failure  to  comply  with 
applicable requirements, could adversely affect our business 
and results of operation.

Our insurance and reinsurance subsidiaries conduct business 
globally  and  are  subject  to  varying  degrees  of  regulation  in 
the  various  jurisdictions  in  which  they  conduct  business, 
including by state, federal and national insurance regulators. 
The purpose of insurance laws and regulations generally is to 
protect  policyholders  and  ceding  insurance  companies,  not 
our shareholders. See “Regulation” in Item 1.

We  may  not  be  able  to  comply  fully  with,  or  obtain 
appropriate  exemptions  from,  these  statutes  and  regulations, 
which could result in restrictions on our ability to do business 
or undertake activities that are regulated in one or more of the 
jurisdictions in which we conduct business and could subject 
us  to  fines  and  other  sanctions.  Regulatory  authorities  also 
may  seek  to  exercise  their  supervisory  or  enforcement 
authority  in  new  or  more  extensive  ways,  such  as  imposing 
increased  capital  requirements.  These  actions,  if  they  occur, 
could affect the competitive market and the way we conduct 
our business and manage our capital and could result in lower 
revenues  and  higher  costs.  As  a  result,  such  actions  could 
have  a  material  effect  on  our  results  of  operations  and 
financial condition.

We  are  subject  to  ongoing  legal  and  policy  actions  around 
climate change which may result in additional requirements 
which could prompt us to shift our risk selection and business 
strategy  in  ways  which  may  adversely  impact  our  results  of 
operations.

Governments,  regulators,  legislators  and  influential  non-
governmental  organizations  continue  to  focus  on  enacting 
laws,  regulations  and  other  requirements  relating  to  climate 
change.  We  are  subject  to  some  of  these  changing  laws, 
regulations  and  public  policy  debates,  which  are  difficult  to 
predict and quantify and may have an adverse impact on our 
business.  Legislative  and  regulatory  initiatives  and  court 
decisions following major catastrophes could force expansion 
of  certain  insurance  coverages  for  catastrophe  claims  or 
otherwise  adversely 
impact  our  business.  Additionally, 
changes in regulations or policies relating to climate change 
or  our  own  leadership  decisions  implemented  as  a  result  of 
assessing the impact of climate change on our business may 
result  in  an  increase  in  the  cost  of  doing  business,  or  a 
decrease in premiums in certain lines of business. 

Our  efforts  to  address  these  exposures  are  based  in  part  on 
the  outcomes  of  our  loss  mitigation  measures  and  risk 
modeling,  our  financial  results  of  operations  and  our 
communications  with  our  customers  and  shareholders.  We 
also  continue  to  monitor  changes  across  our  industry  and 
geographies  and 
these  exposures 
the  Board  considers 
regularly.  We  may  make  strategic  business  decisions  to 
address  or  respond  to  some  of  the  legal  and  policy  changes 
relating to climate change, but there is no assurance that these 
decisions will adequately address these exposures or that they 
will  not  result  in  a  material  adverse  effect  on  our  results  of 
operations, financial condition or share price.

The Russian invasion of Ukraine and the resulting imposition 
of sanctions by the U.S., U.K. and EU on Russia and Russia-
related businesses created global instability.

inflationary  pressures, 

The Russian invasion of Ukraine and ongoing hostilities have 
created  a  high  level  of  uncertainty  as  well  as  disruption  in 
certain  sectors  of  the  global  economy.  It  is  impossible  to 
predict  whether  Russia  will  expand  hostilities  to  other 
countries  in  Europe  or  elsewhere.  A  further  prolonged  war 
may  also  create  uncertainty  in  the  global  economy  in  the 
form  of  oil  shortages, 
loss  of 
confidence  and  general  increase  in  risks  worldwide.  In 
response  to  this  aggression,  the  governments  of  the  U.S., 
U.K., EU and other countries implemented several sanctions 
programs  relating  to,  among  other  things,  the  import  and 
transportation  of  Russian  oil  and  gas  and  other  goods 
originating in Russia. Sanctions imposed also target entities, 
individuals  and  financial  institutions  which  support  Russia’s 
military  and  defense  systems.  Certain  lines  of  business  we 
write  have  been  impacted  by  the  sanctions,  such  as  the 
marine  and  energy  lines  of  business,  although  the  extent  of 

the impact will depend on the outcome of the war in Ukraine 
and the nature of future sanctions packages.

Our  customers  and  policyholders  may  also  be  impacted  by 
regulatory,  technological,  market  or  other  risks  relating  to 
climate  change  in  ways  which  we  cannot  predict  with 
certainty and adversely impact our results of operations.

Our  policyholders  and  customers  are  located  primarily  in 
countries  and  regions,  such  as  the  U.S.,  U.K.,  EU  and 
Australia  where  there  are  regulatory,  policy,  legal  and 
technological  changes  resulting  from  actions  relating  to 
climate  change.  In  some  cases,  those  policyholders  and 
customers may not be able to shift their business strategies or 
adjust adequately to these changes, and their businesses may 
be  negatively  impacted  or,  in  some  cases,  cease  to  exist. 
Climate  change  on  a  global  and  regional  level  may  impact 
businesses  on  a  temporary  or  permanent  basis,  resulting  in 
shifting  needs  for  our  products  and  services  in  ways  we 
cannot  predict.  More  stringent  regulations  and  other 
requirements  imposed  on  our  policyholders  may  negatively 
impact their ability to conduct business. As a result of these 
factors, our results of operations may be impacted by the loss 
of  those  customers  or  a  shift  in  their  patterns  or  levels  of 
insurance coverage in ways we cannot predict.

As we continue to incorporate climate change and other ESG 
factors  in  our  business  strategy,  we  cannot  be  certain  that 
shareholders,  investors  and  other  influential  environmental 
and  social-focused  groups  will  agree  with  our  approach, 
which may adversely impact our ability to raise funds in the 
capital  markets,  our  share  price  and  our  results  of 
operations. 

Shareholders and investors have placed increased importance 
on  how  we  are  addressing  ESG  issues.  ESG  encompass  a 
wide  range  of  issues,  including  climate  change  and  other 
environmental risks. ESG also includes social factors, such as 
how we manage our suppliers, the way we interact with our 
employees  and  communities  and  our  diversity  and  inclusion 
efforts.  Our  leadership  and  Board  are  actively  engaged  in 
understanding 
landscape  and 
the  ever-changing  ESG 
assessing our business operations to ensure that our business 
strategy  reflects  our  values.  We  believe  that  our  success 
depends  on  our  commitment  to  a  diverse  workforce,  an 
informed  and  active  dialogue  about  ESG  issues  with  our 
customers  and  shareholders  and  the  strength  of  our  ERM 
framework.  We  cannot  predict  whether  our  business 
decisions,  business  strategy  and  disclosures  relating  to 
climate  change  and  other  ESG

expectations  or  particular  requirements  of  certain  key 
institutional shareholders in particular. We may be adversely 
impacted  if  shareholders  or  investors  do  not  agree  with,  or 
are not satisfied with, our business strategy and approach to 
climate  change  or  social  concerns  and  decide  to  sell  or  not 
purchase our equity or debt instruments or to publicize their

We  have  substantial  exposure  to  unexpected,  large  losses 
resulting from future man-made catastrophic events, such as 
acts  of  war,  regional  hostilities,  acts  of  terrorism,  political 
instability,  social  unrest  and  pandemics  similar  to  the 
inherently 
COVID-19 
unpredictable.  It  is  difficult  to  predict  the  timing  of  such 
events with statistical certainty or estimate the amount of loss 
any  given  occurrence  will  generate.  In  certain  instances,  we 
specifically  insure  and  reinsure  risks  resulting  from  acts  of 
terrorism.  We  may  also  insure  against  risk  related  to 
cybersecurity and cyber attacks. In addition, our exposure to 
cyber  attacks  includes  exposure  to  ‘silent  cyber’  risks, 
meaning  risks  and  potential  losses  associated  with  policies 
where cyber risk is not specifically included nor excluded in 
the  policies.  Even  in  cases  where  we  attempt  to  exclude 
losses from terrorism, cybersecurity and certain other similar 
risks  from  some  coverages  written  by  us,  we  may  not  be 
successful  in  doing  so.  Moreover,  irrespective  of  the  clarity 
and  inclusiveness  of  policy  language,  there  can  be  no 
assurance  that  a  court  or  arbitration  panel  will  not  limit 
enforceability of policy language or otherwise issue a ruling 
adverse to us. Accordingly, while we believe our reinsurance 
programs,  together  with  the  coverage  provided  under  the 
Terrorism Risk Insurance Act of 2002, as amended (“TRIP”) 
are  sufficient  to  reasonably  limit  our  net  losses  relating  to 
potential  future  terrorist  attacks,  we  can  offer  no  assurance 
that  our  available  capital  will  be  adequate  to  cover  losses 
when they materialize. To the extent that an act of terrorism 
is  certified  by  the  Secretary  of  the  Treasury  and  aggregate 
industry  insured  losses  resulting  from  the  act  of  terrorism 
exceeds  the  prescribed  program  trigger,  our  U.S.  insurance 
operations may be covered under TRIP for up to 80% subject 
to  (i)  a  mandatory  deductible  of  20%  of  our  prior  year’s 
direct  earned  premium  for  covered  property  and  liability 
coverages,  and  (ii)  an  industry  aggregate  retention  of  $37.5 
billion. The program trigger for calendar year 2023 and any 
program  year  thereafter  through  2027  is  $200  million.  If  an 
act  (or  acts)  of  terrorism  result  in  covered  losses  exceeding 
the $100 billion annual limit, insurers with losses exceeding 
their deductibles will not be responsible for additional losses. 
It  is  not  possible  to  completely  eliminate  our  exposure  to 
unforecasted  or  unpredictable  events,  and  to  the  extent  that 
losses  from  such  risks  occur,  our  financial  condition  and 
results of operations could be materially adversely affected.

Our  success  is  dependent  upon  our  ability  to  assess 
accurately  the  risks  associated  with  the  businesses  that  we 
insure and reinsure. We establish reserves for losses and loss 
adjustment  expenses  which  represent  estimates  based  on 
actuarial  and  statistical  projections,  at  a  given  point  in  time, 
of  our  expectations  of  the  ultimate  future  settlement  and 
administration  costs  of  losses  incurred.  We  utilize  actuarial 
models as well as available historical insurance industry loss 
ratio experience and loss development patterns to assist in the 
establishment of loss reserves. Most or all of these factors are 
not  directly  quantifiable,  particularly  on  a  prospective  basis, 
and  the  effects  of  these  and  unforeseen  factors  could 
negatively impact our ability to accurately assess the risks of 
the  policies  that  we  write.  Changes  in  the  assumptions  used 
by these models or by management could lead to an increase 
in  our  estimate  of  ultimate  losses  in  the  future.  In  addition, 
there  may  be  significant  reporting 
the 
occurrence of the insured event and the time it is reported to 
the insurer and additional lags between the time of reporting 
and final settlement of claims. In addition, the estimation of 
loss  reserves  is  more  difficult  during  times  of  adverse 
economic  and  market  conditions  due  to  unexpected  changes 
in  behavior  of  claimants  and  policyholders,  including  an 
increase  in  fraudulent  reporting  of  exposures  and/or  losses, 
reduced  maintenance  of  insured  properties  or  increased 
frequency  of  small  claims.  Changes  in  the  level  of  inflation 
also  result  in  an  increased  level  of  uncertainty  in  our 
estimation of loss reserves. As a result, actual losses and loss 
adjustment  expenses  paid  can  deviate,  perhaps  substantially, 
from 
in  our  financial 
statements.

If our loss reserves are determined to be inadequate, we will 
be  required  to  increase  loss  reserves  at  the  time  of  such 
determination  with  a  corresponding  reduction  in  our  net

is possible that claims in respect of events that have occurred 
could exceed our claim reserves and have a material adverse 
effect  on  our  results  of  operations,  in  a  particular  period,  or 
our financial condition in general. As a compounding factor, 
although  most  insurance  contracts  have  policy  limits,  the 
nature of property and casualty insurance and reinsurance is 
such  that  losses  and  the  associated  expenses  can  exceed 
policy limits for a variety of reasons and could significantly 
exceed  the  premiums  received  on  the  underlying  policies, 
thereby further adversely affecting our financial condition.

As  of  December  31,  2023,  our  consolidated  reserves  for 
unpaid  losses  and  loss  adjustment  expenses,  net  of  unpaid 
losses  and  loss  adjustment  expenses  recoverable,  were 
approximately  $16.1  billion.  Such  reserves  were  established 
in  accordance  with  applicable  insurance  laws  and  GAAP. 
Loss  reserves  are  inherently  subject  to  uncertainty.  In 
establishing  the  reserves  for  losses  and  loss  adjustment 
expenses, we have made various assumptions relating to the 
pricing  of  our  reinsurance  contracts  and  insurance  policies 
industry 
and  have  also  considered  available  historical 
experience  and  current  industry  conditions.  Any  estimates 
and assumptions made as part of the reserving process could 
prove  to  be  inaccurate  due  to  several  factors,  including  the 
fact  that  for  certain  lines  of  business  relatively  limited 
historical  information  has  been  reported  to  us  through 
December 31, 2023.

The  failure  of  any  of  the  loss  limitation  methods  we  employ 
could  have  a  material  adverse  effect  on  our  financial 
condition or results of operations.

We  seek  to  limit  our  loss  exposure  by  writing  a  number  of 
our reinsurance contracts on an excess of loss basis, adhering 
to  maximum  limitations  on  reinsurance  written  in  defined 
geographical zones, limiting program size for each client and 
prudent underwriting of each program written. In the case of 
proportional treaties, we may seek per occurrence limitations 
or loss ratio caps to limit the impact of losses from any one or 
series of events. In our insurance operations, we seek to limit 
our  exposure  through  the  purchase  of  reinsurance.  For  our 
U.S.  mortgage  insurance  business,  in  addition  to  utilizing 
reinsurance, we have developed a proprietary risk model that 
simulates the maximum probable loss resulting from a severe 
economic event impacting the housing market. We also seek 
to  limit  our  loss  exposure  by  geographic  diversification, 
including  by  pricing  adjustments  in  our  U.S.  mortgage 
insurance  business.  Geographic  pricing  decisions  and  zone 
limitations 
judgments, 
involve  significant  underwriting 
including the determination of the area of the zones and the 
inclusion  of  a  particular  policy  within  a  particular  zone’s 
limits. Various provisions of our policies, negotiated to limit 
our  risk,  such  as  limitations  or  exclusions  from  coverage  or 
choice  of  forum,  may  not  be  enforceable  in  the  manner  we 
intend,  as  it  is  possible  that  a  court  or  regulatory  authority 
could nullify or void an exclusion or limitation, or legislation 
could  be  enacted  modifying  or  barring  the  use  of  these 
exclusions and limitations. Disputes relating to coverage and 
choice  of  legal  forum  may  also  arise.  Underwriting  is 
inherently  a  matter  of 
important 
assumptions  about  matters  that  are  inherently  unpredictable 
and  beyond  our  control,  and  for  which  historical  experience 
and probability analysis may not provide sufficient guidance. 
One  or  more  catastrophic  events  or  severe  economic  events 
could  result 
that  substantially  exceed  our 
expectations, or the protections set forth in our policies could 
be  voided,  which,  in  either  case,  could  have  a  material

the  extent  of  eliminating  our 
operations,  possibly 
shareholders’  equity.  In  addition,  factors  such  as  global 
climate  change  limit  the  value  of  historical  experience  and 
therefore further limit the effectiveness of our loss limitation 
methods.  See  “Catastrophic  Events  and  Severe  Economic 
Events” in Item 7 for further details. Depending on business 
opportunities and the mix of business that may comprise our 
insurance,  reinsurance  and  mortgage  insurance  portfolio,  we 
may  seek  to  adjust  our  self-imposed  limitations  on  probable 
maximum  pre-tax  loss  for  catastrophe  exposed  business  and 
mortgage default exposed business.

The availability of reinsurance, retrocessional coverage and 
capital market transactions to limit our exposure to risks may 
be limited, and counterparty credit and other risks associated 
with  our  reinsurance  arrangements  may  result  in  losses 
which  could  adversely  affect  our  financial  condition  and 
results of operations.

In 

addition,  our 

We  manage  risk  using  reinsurance,  retrocessional  coverage 
and  capital  markets  transactions.  Our  insurance  subsidiaries 
typically  cede  a  portion  of  their  premiums  through  pro  rata, 
excess  of  loss  and  facultative  reinsurance  agreements.  Our 
reinsurance  subsidiaries  purchase  a  limited  amount  of 
retrocessional  coverage  as  part  of  their  aggregate  risk

subsidiaries  participate  in  “common  account”  retrocessional 
arrangements for certain pro rata treaties. Such arrangements 
reduce  the  effect  of  individual  or  aggregate  losses  to  all 
companies  participating  on  such  treaties,  including  the 
reinsurers,  such  as  our  reinsurance  subsidiaries,  and  the 
ceding  company.  Economic  conditions,  including  but  not 
limited  to  recessionary  conditions,  inflation,  declining  home 
prices  or  the  impact  of  climate  change  could  also  have  a

through 

Further,  we  are  subject  to  credit  risk  with  respect  to  our 
reinsurance  and  retrocessions  because  the  ceding  of  risk  to 
reinsurers  and  retrocessionaires  does  not  relieve  us  of  our 
liability to the clients or companies we insure or reinsure. We 
monitor the financial condition of our reinsurers and attempt 
to place coverages only with carriers we view as substantial 
and  financially  sound.  An  inability  of  our  reinsurers  or 
retrocessionaires to meet their obligations to us could have a 
material adverse effect on our financial condition and results 
of operations. Our losses for a given event or occurrence may 
increase  if  our  reinsurers  or  retrocessionaires  dispute  or  fail

to  meet  their  obligations  to  us  or  the  reinsurance  or 
retrocessional  protections  purchased  by  us  are  exhausted  or 
are otherwise unavailable for any reason. In certain instances, 
we  also  require  collateral  to  mitigate  our  credit  risk  to  our 
reinsurers  or  retrocessionaires.  We  are  at  risk  that  losses 
could exceed the collateral we have obtained. Our failure to 
establish adequate reinsurance or retrocessional arrangements 
or  the  failure  of  our  existing  reinsurance  or  retrocessional 
arrangements  to  protect  us  from  overly  concentrated  risk 
exposure  could  adversely  affect  our  financial  condition  and 
results of operations.

We  could  be  materially  adversely  affected  to  the  extent  that 
important  third  parties  with  whom  we  do  business  do  not 
adequately  or  appropriately  manage  their  risks,  commit 
fraud or otherwise breach obligations owed to us. 

For  certain  lines  of  our  insurance  business,  we  authorize 
managing general agents, general agents and other producers 
to  write  business  on  our  behalf  within  underwriting 
authorities prescribed by us. In addition, our mortgage group 
delegates  the  underwriting  of  a  significant  percentage  of  its 
primary  new  insurance  written  to  certain  mortgage  lenders. 
Under  this  delegated  underwriting  program,  the  approved 
customer  may  determine  whether  mortgage  loans  meet  our 
mortgage  insurance  program  guidelines  and  commit  us  to 
issue  mortgage  insurance.  We  rely  on  the  underwriting 
controls  of  these  agents  to  write  business  within  the 
underwriting  authorities  provided  by  us.  Although  we  have 
contractual  protections  in  some  instances  and  we  monitor 
such  business  on  an  ongoing  basis,  our  monitoring  efforts 
may  not  be  adequate  or  our  agents  may  exceed  their 
underwriting  authorities  or  otherwise  breach  obligations 
owed  to  us.  In  addition,  our  agents,  our  insureds  or  other 
third  parties  may  commit  fraud  or  otherwise  breach  their 
obligations  to  us.  Our  financial  condition  and  results  of 
operations could be materially adversely affected by any one 
of these issues.

While  we  conduct  underwriting,  financial,  claims  and 
information  technology  due  diligence  reviews  and  apply 
rigorous  standards  in  the  selection  of  these  counterparties, 
there  is  no  assurance  they  have  provided  us  accurate  or 
complete  information  to  assess  their  risk  or  that  they  can 
manage  effectively  their  own  risks.  The  counterparties  are 
also  subject  to  the  same  global  increase  in  cyber  incidents, 
including  ransomware,  and  we  cannot  offer  assurances  that

industry  practices  and 

As 
social  and  other 
environmental conditions change, unexpected and unintended 
issues related to claims and coverage may emerge, including 
new or expanded theories of liability. These or other changes 
could  impose  new  financial  obligations  on  us  by  extending 
coverage beyond our underwriting intent or otherwise require 
us  to  make  unplanned  modifications  to  the  products  and 
services that we provide, or cause the delay or cancellation of 
products  and  services  that  we  provide.  In  some  instances, 
these changes may not become apparent until sometime after 
we  have  issued  insurance  or  reinsurance  contracts  that  are 
affected by the changes. As a result, the full extent of liability 
under  our  insurance  or  reinsurance  contracts  may  not  be 
known for many years after a contract is issued. The effects 
of  unforeseen  developments  or  substantial  government 
intervention could adversely impact us.

While we had exposure to a number of lines of business, such 
as  trade  credit,  travel,  workers  compensation  and  property 
where business interruption coverage under a pandemic such 
as COVID-19 was at issue, the number of claims in this area 
has decreased greatly in 2022. and into 2023. We continue to 
monitor  the  impact  of  COVID-19  on  our  claims  process  in 
the U.S and U.K. in particular, although we do not expect the 
impact to be significant.

Acquisitions,  the  addition  of  new  lines  of  insurance  or 
reinsurance business, expansion into new geographic regions 
and/or entering into joint ventures or partnerships expose us 
to risks.

We may seek, from time to time, to acquire other companies, 
acquire  selected  blocks  of  business,  expand  our  business 
lines,  expand  into  new  geographic  regions  and/or  enter  into 
joint  ventures  or  partnerships.  Such  activities  expose  us  to 
challenges  and  risks,  including:  integrating  financial  and 
reporting  systems;  establishing  satisfactory 
operational 
budgetary  and  other  financial  controls;  funding  increased 
capital needs, overhead expenses or cash flow shortages that 
may  occur  if  anticipated  sales  and  revenues  are  not  realized 
or  are  delayed,  whether  by  general  economic  or  market 
conditions  or  unforeseen  internal  difficulties;  obtaining 
management  personnel  required  for  expanded  operations; 
obtaining necessary regulatory permissions; and establishing 
adequate  reserves  for  any  acquired  book  of  business.  In 
addition,  the  value  of  assets  acquired  may  be  lower  than 
expected or may diminish due to credit defaults or changes in 
interest  rates;  the  liabilities  assumed  may  be  greater  than 
expected; and assets and liabilities acquired may be subject to

subject to financial exposures in the event that the sellers of

Our  customers,  require  that  we  conduct  our  business  in  a 
secure  manner,  electronically  via

in  establishing  and  maintaining 
significant 
electronic  connectivity  with  customers.  In  order  to  integrate

systems  and  leading  pricing  and  loan  origination  systems. 
Our  mortgage  group  currently  possesses  connectivity  with 
certain  of  these  external  systems,  but  there  is  no  assurance 
that  such  connectivity  is  sufficient,  and  we  are  continually

malicious  intent,  state-sponsored  cyber  attacks,  as  well  as 
vulnerabilities  relating 
technologies,  such  as 
to  new 
generative  AI,  may  impact  us  or  our  business  partners  and 
service  providers,  causing  a  disruption  in  service  and 
operations which could materially and negatively impact our 
business and/or expose us to litigation. 

We  rely  on  information  technology  systems  to  securely 
process,  transmit,  store  and  protect  the  confidential  and 
electronic information, financial data and proprietary models 
that  are  critical  to  our  business.  Furthermore,  a  significant 
portion  of  the  communications  between  our  employees  and 
our  business  partners  and  service  providers  depends  on 
information technology and electronic information exchange. 
Like all companies, our information technology systems and 
the  systems  of  third  parties  we  do  business  with  are 
vulnerable  to  data  breaches,  interruptions  or  failures  due  to 
events  that  may  be  beyond  our  control,  including,  but  not 
limited  to,  natural  disasters,  power  outages,  theft,  terrorist 
attacks, computer viruses, hackers, employee or vendor error 
or misconduct, malicious actors, errors in usage or deepfake 
or  social  engineering  or  schemes,  phishing  attacks,  other 
external  hazards  and  general  technology  failures.  Security 
breaches  by  third  parties  could  expose  us  to  the  loss  or 
misuse  of  our  information,  financial  losses,  reputational 
damage  and  potential  liability  and  litigation.  In  addition, 
cyber  incidents  and  other  disruptions  that  impact  the 
availability,  reliability,  speed,  accuracy  or  other  proper 
functioning  of  these  systems  could  have  a  significant 
negative impact on our operations and results. While we and 
third  parties  with  which  we  do  business  have  experienced 
cybersecurity  incidents,  to  date,  the  Company  does  not 
believe  that  any  previous  cybersecurity  incidents  have 
materially affected the Company.

The sophistication of cybersecurity threats, including through 
the  use  of  AI,  continues  to  increase,  and  the  controls  and 
preventative  actions  that  we  take  to  reduce  the  risk  of 
cybersecurity  incidents  and  protect  these  systems,  including 
the  regular  testing  of  our  cybersecurity  incident  response 
plan, may be insufficient. Although our use of generative AI 
in business tools is limited and we continue to evaluate how 
to integrate this new technology into our business operations, 
recent  developments  in  AI,  including  generative  AI,  may 
accelerate  or  exacerbate  potential 
to 
technological developments, and we cannot predict how such 
risks  may 
impact  our  strategy,  productivity,  market 
competition and growth.

or 
information  security  failures  and  failure  to  train  employees 
appropriately  or  adequately.  We  continuously  enhance  our 
operating  procedures  and  internal  controls  to  effectively 
support  our  business  and  our  regulatory  and  reporting 
requirements.  As  a  result  of  the  inherent  limitations  in  all 
control  systems,  no  evaluation  of  controls  can  provide 
absolute  assurance  that  all  control  issues  and  instances  of 
fraud, if any, within the company have been detected. These 
inherent  limitations  include  the  realities  that  judgments  in 
decision  making  can  be  faulty,  and  that  breakdowns  can 
occur because of simple error or mistake or circumvention of 
controls.  There  can  be  no  assurance  that  our  control  system 
will  succeed  in  achieving  its  stated  goals  under  all  potential 
future  conditions.  Any  ineffectiveness  in  our  controls  or 
procedures  could  have  a  material  adverse  effect  on  our 

business.  For  further  information  on  our  ERM  framework, 
see “Enterprise Risk Management” in Item 1.

We  are  exposed  to  credit  risk  in  certain  of  our  business 
operations.

In  addition  to  exposure  to  credit  risk  related  to  our 
investment  portfolio,  reinsurance  recoverables  and  reliance 
on brokers and other agents, we are exposed to credit risk in 
other  areas  of  our  business  related  to  policyholders.  We  are 
exposed  to  credit  risk  in  our  insurance  group’s  surety  unit 
where we guarantee to a third party that our policyholder will 
satisfy  certain  performance  or  financial  obligations.  If  our 
policyholder defaults, we may suffer losses and be unable to 
be  reimbursed  by  our  policyholder.  We  are  also  exposed  to 
credit risk from policyholders on smaller deductibles in other 
insurance  group  lines,  such  as  healthcare  and  excess  and 
surplus  casualty.  Although  we  have  not  experienced  any 
material  credit  losses  to  date,  an  increased  inability  of  our 
policyholders  to  meet  their  obligations  to  us  could  have  a 
material adverse effect on our financial condition and results 
of operations. See note 3, “Significant Accounting Policy.”

Our  business  is  subject  to  applicable  laws  and  regulations 
relating  to  economic  trade  sanctions  and  foreign  bribery 
laws,  the  violation  of  which  could  adversely  affect  our 
operations.

We must comply with all applicable economic sanctions and 
anti-bribery  laws  and  regulations  of  the  U.S.  and  other 
foreign  jurisdictions  where  we  operate.  U.S.  laws  and 
regulations applicable to us and others who provide insurance 
and  reinsurance  include  the  economic  trade  sanctions  laws 
and  regulations  administered  by  the  Treasury’s  Office  of 
Foreign  Assets  Control  as  well  as  certain  laws  administered 
by the U.S. Department of State. New sanctions regimes may 
be  initiated,  or  existing  sanctions  expanded,  at  any  time, 
which can immediately impact our business activities. Since 
the Russian invasion of Ukraine in February 2022, there have 
been  several  sanctions  packages  imposed  by  the  U.S.,  U.K. 
and  EU  which  impact  our  business.  The  sanctions  are 
complex, numerous and nuanced, requiring close review and 
assessment  as  they  pertain  to  our  business.  We  are  also 
subject  to  the  U.S.  Foreign  Corrupt  Practices  Act  and  other 
anti-bribery laws such as the U.K. Bribery Act that generally 
bar  corrupt  payments  or  unreasonable  gifts  to  foreign 
governments  or  officials.  Although  we  have  policies  and 
controls  in  place  designed  to  ensure  compliance  with  these 
laws  and  regulations,  it  is  possible  that  an  employee  or 
intermediary  could  fail  to  comply  with  applicable  laws  and 
regulations. In addition, we may interpret a complex sanction 
in  a  way  which  may  differ  from  a  regulator.  In  these  cases, 
we  could  be  exposed  to  fines,  criminal  penalties  and  other 
sanctions.  Such  violations  could  limit  our  ability  to  conduct 
business and/or damage our reputation, resulting in a material 
adverse  effect  on  our  financial  condition  and  results  of 
operations.

New  legislation  or  regulations  relating  to  the  U.K.’s 
Withdrawal from the EU could adversely affect us. 

The U.K. ceased to be a member state of the European Union 
in January 2020. Although the EU and U.K. reached a limited 
agreement  in  relation  to  certain  matters,  U.K.  insurers  and

Risks Relating to Financial Markets and Investments

Adverse developments in the financial markets could have a 
material adverse effect on our results of operations, financial 
position and our businesses, and may also limit our access to 
capital;  our  policyholders,  reinsurers  and  retrocessionaires 
may  also  be  affected  by  such  developments,  which  could 
adversely affect their ability to meet their obligations to us.

Adverse  developments  in  the  financial  markets,  resulting 
from  inflation,  global  recessionary  pressures,  geopolitical 
conflict,  liquidity  conditions  among  other  factors,  can 
increase uncertainty and heighten volatility in the credit and 
equity  markets.  These  developments  may  result  in  realized 
and  unrealized  losses  on  our  investment  portfolio  that  could 
have  a  material  adverse  effect  on  our  results  of  operations, 
financial position and our businesses, and may also limit our 
access to capital required to operate our business. In addition, 
our  policyholders,  reinsurers  and  retrocessionaires  may  be 
affected  by  developments  in  the  financial  markets,  which 
could adversely affect their ability to meet their obligations to 
us.  Volatility  in  the  financial  markets  could  continue  to 
significantly  affect  our  investment  returns,  reported  results 
and shareholders’ equity.

The  capital  requirements  of  our  businesses  depend  on  many 
factors, including regulatory and rating agency requirements, 
the  performance  of  our  investment  portfolio,  our  ability  to 
write  new  business  successfully,  the  frequency  and  severity 
of  catastrophe  events  and  our  ability  to  establish  premium 
rates and reserves at levels sufficient to cover losses.

Disruption  to  the  financial  markets  and  weak  economic 
conditions  resulting  from  situations  such  as  post  pandemic 
imbalances, inflation and geopolitical conflict may adversely 
and  materially  impact  our  investments,  financial  condition 
and results of operation.

Disruption  in  the  financial  markets  and  the  downturn  in 
global economic activity resulting from geopolitical conflict, 
elevated  financing  rates,  housing  market  declines  or  other 
macro-and micro-economic conditions could adversely affect 
the valuation of securities in our investment portfolio. Credit 
deterioration spread widening and/or equity market volatility 
could result in temporary or permanent impairment. Elevated 
levels of inflation could drive higher U.S. and global interest 
rates, negatively impacting asset prices, particularly in fixed 
income  and  financial  flexibility  of  operating  businesses.  In 
addition,  a  lack  of  pricing  transparency,  decreased  market 
liquidity, 
foreign 
the  strengthening  or  weakening  of 
currencies against the U.S. Dollar, individually or in tandem, 
could  have  a  material  adverse  effect  on  our  results  through 
realized  losses,  impairments  and  changes  in  unrealized 
positions in our investment portfolio. Furthermore, issuers of 
the  investments  we  hold  under  the  equity  method  of 
accounting report their financial information to us one month 
to  three  months  following  the  end  of  the  reporting  period. 
Accordingly, the adverse impact of any disruptions in global 
financial  markets  on  equity  method  income  from  these 
investments  would  likely  not  be  reflected  in  our  current 
quarter  results  and  would  instead  be  reported  in  the 
subsequent quarter. 

Our  operating  results  depend  in  part  on  the  performance  of 
our  investment  portfolio.  A  significant  portion  of  cash  and 
invested  assets  held  by  Arch  consists  of  fixed  maturities 
(70.1%  as  of  December  31,  2023).  Although  our  current 
investment  guidelines  and  approach  emphasize  preservation 
of  capital,  market  liquidity  and  diversification  of  risk,  our 
investments are subject to market-wide risks and fluctuations. 
In  addition,  we  are  subject  to  risks  inherent  in  particular 
types  of  securities,  as  well  as  sector 
securities  or 
concentrations. We may not be able to realize our investment 
objectives, which could have a material adverse effect on our 
financial  results.  In  the  event  that  we  are  unsuccessful  in 
calibrating the liquidity of our investment portfolio with our 
expected  insurance  and  reinsurance  liabilities,  we  may  be 
forced  to  liquidate  our  investments  at  times  and  prices  that 
are  not  optimal,  which  could  have  a  material  adverse  effect 
on our financial results and ability to conduct our business.

Foreign  currency  exchange  rate  fluctuation  may  adversely 
affect our financial results.

We  write  business  on  a  worldwide  basis,  and  our  results  of 
operations  may  be  affected  by  fluctuations  in  the  value  of 
currencies  other  than  the  U.S.  Dollar.  The  primary  foreign 
currencies  in  which  we  operate  are  the  Euro,  the  British 
Pound  Sterling,  the  Australian  Dollar  and  the  Canadian 
Dollar. In order to minimize the possibility of losses we may 
suffer  as  a  result  of  our  exposure  to  foreign  currency 
fluctuations  in  our  net  insurance  liabilities,  we  invest  in 
securities  denominated  in  currencies  other  than  the  U.S. 
Dollar. In addition, we may replicate investment positions in 
foreign  currencies  using  derivative  financial  instruments. 
Changes in the value of available-for-sale investments due to 
foreign  currency  rate  movements  are  reflected  as  a  direct 
increase  or  decrease  to  shareholders'  equity  and  are  not 
included in the statement of income.

The  determination  of  the  amount  of  current  expected  CECL 
allowances taken on our investments is highly subjective and 
could materially impact our results of operations or financial 
position.

On a quarterly basis, we review our investments by applying 
an approach based on the CECL and whether declines in fair 
value  below  the  cost  basis  requires  an  estimate  of  the 
expected  credit  loss.  There  can  be  no  assurance  that  our 
management  has  accurately  assessed  the  level  of  the  credit 
loss allowance taken, as reflected in our financial statements. 
Furthermore,  additional  allowance  may  need  to  be  taken  or 
allowances  provided  for  in  the  future.  Further,  rapidly 
changing  and  unpredictable  credit  and  equity  market 
conditions  could  materially  affect  the  valuation  of  securities 
carried  at  fair  value  as  reported  within  our  consolidated 
financial  statements  and  the  period-to-period  changes  in 
value could vary significantly.

Our  reinsurance  subsidiaries  may  be  required  to  provide 
collateral  to  ceding  companies,  by  applicable  regulators, 
their  contracts  or  other  commercial  considerations.  Their 
ability  to  conduct  business  could  be  significantly  and 
negatively affected if they are unable to do so.

Arch  Re  Bermuda  is  a  registered  Bermuda  insurance 
company and is not licensed or admitted as an insurer in any 
jurisdiction in the U.S., although Arch Re Bermuda has been 
approved as a “certified reinsurer” in certain U.S. states that 
allow  reduced  collateral  for  reinsurance  ceded  to  such 
reinsurers.  Arch  Re  Bermuda's  contracts  generally  require  it 
to  post  a  letter  of  credit  or  provide  other  security,  even  in 
U.S. states where it has been approved for reduced collateral. 
State  credit  for  reinsurance  rules  also  generally  provide  that 
certified  reinsurers  such  as  Arch  Re  Bermuda  must  provide 
100%  collateral  in  the  event  their  certified  status  is 
“terminated”  or  upon  the  entry  of  an  order  of  rehabilitation, 
liquidation or conservation against a ceding insurer. 

Although, to date, Arch Re Bermuda has not experienced any 
difficulties  in  providing  collateral  when  required,  if  we  are 
unable to post security in the form of letters of credit or trust 
funds  when  required,  the  operations  of  Arch  Re  Bermuda 
could be significantly and negatively affected.

Risks Relating to Our Mortgage Operations

The  ultimate  performance  of  our  mortgage 
portfolios remains uncertain.

insurance 

The mix of business in our insured loan portfolio may affect 
losses. The presence of multiple higher-risk characteristics in 
a  loan  materially  increases  the  likelihood  of  a  claim  unless 
there are other characteristics to mitigate the risk. The mix of 
higher-risk  loans,  including  affordable  housing  loans  which 
often  have  higher-risk  characteristics,  could  increase  losses 
and harm our financial performance. The geographic mix of 
our insured loan portfolio could also increase losses and harm 
our financial performance.

Mortgage insurance premiums are set at the time coverage is 
procured,  based  in  part  on  the  expected  duration  of  the 
coverage. We cannot cancel mortgage insurance coverage or 
adjust renewal premiums during the life of the policy. Thus, 
higher  than  anticipated  claims  generally  cannot  be  offset  by 
premium  increases  on  policies  in  force  or  mitigated  by  our 
non-renewal  or  cancellation  of  insurance  coverage.  Further, 
in the U.S., to the extent that the insured cancels coverage as 
a  result  of  prior  home  price  appreciation,  the  duration  of 
coverage  will  be  shorter,  and  we  will  receive  less  premium. 
The  premiums  charged,  and  the  associated  investment 
income, may not be adequate to compensate us for the risks 
and costs associated with the insurance coverage provided to 
customers. A decrease in the amount of premium received or 
an increase in the number or size of claims, compared to what 
we anticipate, could adversely affect our results of operations 
and financial condition.

including,  among  others,  changes 

The  frequency  and  severity  of  claims  we  incur  is  uncertain 
and will depend largely on general economic factors outside 
of  our  control, 
in 
unemployment  and  home  prices  affordability.  Inflated  home 
prices  followed  by  a  decline 
in  home  values  could 
significantly  decrease  a  borrower’s  equity  in  their  home, 
which  would  limit  their  ability  to  sell  the  property  without 
incurring a loss and could increase the frequency and severity 
of  claims.  Monthly  interest  rate  changes  in  Australia  or  the 
increasing  cost  of  homeowners  insurance  in  the  U.S.  could 
make  a  borrower’s  monthly  housing-related  payment 
obligations  increase  and  could  increase  the  frequency  of 
claims. Deteriorating economic conditions, potentially due to 
levels  of 
prolonged  recessionary  conditions

adversely  affect  our  results  of  operations  and  financial 
condition.

If  the  volume  of  low  down  payment  mortgage  originations 
declines,  or  if  other  government  housing  policies,  practices 
or regulations change, the amount of mortgage insurance we 
write  in  the  U.S.  could  decline,  which  would  reduce  our 
mortgage insurance revenues.

The  size  of  the  U.S.  mortgage  insurance  market  depends  in 
large  part  upon  the  volume  of  low  down  payment  home 
mortgage  originations.  Factors  affecting  the  volume  of  low 
down payment mortgage originations include, among others: 
restrictions on mortgage credit due to stringent underwriting 
standards  and  liquidity  issues  affecting  lenders;  changes  in 
mortgage interest rates and home prices, and other economic 
conditions  in  the  U.S.  and  regional  economies;  population 
trends,  including  the  rate  of  household  formation;  and  U.S. 
government  housing  policy.  Increases  to  mortgage  interest 
rates  have  materially  increased  financing  costs,  and  as  a 
result  may  decrease  the  number  of  qualified  borrowers  and 
the volume of low down payment mortgage originations.

The  private  mortgage 
insurers’  principal  government 
competitor  is  the  Federal  Housing  Administration  (“FHA”). 
On February 22, 2023, the FHA reduced its annual mortgage 
insurance  premium  rates  by  30bps  for  most  single  family 
mortgages  endorsed  on  or  after  March  20,  2023.  This  takes 
the  annual  premium  from  0.85%  down  to  0.55%  for  most 
FHA borrowers. This change, and any future changes to the 
FHA  program  may,  negatively  impact  the  amount  of 
mortgage insurance we write in the U.S. 

The  Federal  Housing  Finance  Agency 
(“FHFA”)  as 
conservator  of  the  GSEs  continues  to  evaluate  loan  level 
price adjustments (“LLPAs”) and guarantees fees assessed by 
the GSEs when purchasing loans. During 2022 and 2023, the 
FHFA implemented a series of changes to update the GSEs’ 
single-family  guarantee  fee  pricing  framework  to  increase 
support  for  creditworthy  borrowers  limited  by  income  or  by 
wealth,  while  also  increasing  pricing  to  other  categories  of 
loans  (such  as  high  balance  mortgages  and  mortgages  on 
second  homes)  to  foster  capital  accumulation.  On  May  15, 
2023,  FHFA  issued  a  Request  for  Input  (“RFI”)  on  the 
process used for implementing guarantee fee pricing changes, 
and  on  the  goals  and  priorities  that  FHFA,  as  both 
conservator  and  regulator,  should  pursue  in  its  oversight  of 
the  pricing  framework.  These,  and  future  actions  taken  as  a 
result of the RFI could cause a decline in the volume of low-
down payment home mortgage purchases by the GSEs, could 
decrease demand for mortgage insurance, and could decrease 
our  U.S.  new  insurance  written  and  reduce  mortgage 
insurance revenues.

On June 8, 2022, the FHFA announced the GSEs release of 
Fannie  Mae's  and  Freddie  Mac's  Equitable  Housing  Finance 
Plans  for  2022-2024.  These  plans  are  designed  to  foster 
housing  finance  markets  that  provide  equitable  access  to 
affordable and sustainable housing, including through the use 
of  special  purpose  credit  programs  (“SPCPs”).  SPCPs  are 
lending programs designed to expand access to credit among 
disadvantaged  borrowers.  The  Consumer  Finance  Protection 
Bureau, the Department of Housing and Urban Development, 
and other federal agencies have issued guidance encouraging 
the  use  of  SPCPs  and  providing  assurances  that  properly 
structured  SPCPs  are  permissible  under  federal  law.  New 
practices  or  programs 
the  GSEs’ 
Equitable  Housing  Plans,  may  impact  the  underwriting  and 
servicing standards on mortgages purchased by the GSEs and 
could 
the  presence  of  multiple  higher-risk 
characteristics in our insured loan portfolio. Further, the legal 
landscape  applicable  to  SPCPs  remains  untested  and  loans 
originated under these programs could be subject to increased 
risk  of  private  litigation  or  enforcement  actions  under  state 
and federal law.

Changes to the role of the GSEs in the U.S. housing market 
or  to  GSE  eligibility  requirements  for  mortgage  insurers  or 
to the GSEs’ use of CRT could negatively impact our results 
of  operations  and 
financial  condition  or  reduce  our 
operating flexibility.

Substantially  all  of  Arch  MI  U.S.’s  insurance  written  has 
been  for  loans  sold  to  the  GSEs.  The  charters  of  the  GSEs 
require credit enhancement for low down payment mortgages 
to  be  eligible  for  purchase  or  guarantee  by  the  GSEs.  Any 
changes  to  the  charters  or  statutory  authorities  of  the  GSEs 
would  require  congressional  action  to  implement.  If  the 
charters  of  the  GSEs  were  amended  to  change  or  eliminate 
the acceptability of private mortgage insurance, our mortgage 
insurance business could decline significantly. 

In  January  2021,  the  U.S.  Department  of  Treasury  (the 
“Treasury Department”) and FHFA announced an agreement 
to  amend  the  preferred  stock  purchase  agreements  between 
the  Treasury  Department  and  the  GSEs,  originally  entered 
into  in  September  2008,  in  order  to,  among  other  things, 
codify  several  existing  FHFA  conservatorship  practices  for 
the GSEs and outline a plan for the Treasury Department, in 
consultation with FHFA, to develop a proposal for continued 
GSE reform. If any GSE reform is adopted, whether through 
legislation  or  administrative  action,  it  could  impact  the 
current  role  of  private  mortgage 
insurance  as  credit 
enhancement, including its reduction or elimination. Passage 
and timing of any comprehensive GSE reform or incremental 
change (legislative or administrative) is uncertain, making the 
actual impact on the mortgage insurance industry difficult to 
predict. Furthermore, the FHFA and/or the GSEs could chose 
to  reduce  the  amount  of  CRT  protection  purchased  on  their 
loan  portfolios,  which  could  reduce  the  CRT  investment

administrative or changes to business practices related to the

material adverse impact on the Company.

The  PMIERs  apply  to  Arch  Mortgage  Insurance  Company 
and United Guaranty Residential Insurance Company, which 
are  GSE-approved  mortgage  insurers  (“eligible  mortgage 
insurers”).  The  PMIERs  impose  limitations  on  the  type  of 
risk  insured,  the  forms  and  insurance  policies  issued, 
standards for the geographic and customer diversification of 
risk,  acceptable  underwriting  practices,  quality  assurance, 
loss  mitigation,  claims  handling,  standards  for  certain 
reinsurance cessions and financial requirements, among other 
things.  The  financial  requirements  require  a  mortgage 
insurer’s  available  assets  to  meet  or  exceed  “minimum 
required  assets”  as  of  each  quarter  end.  Arch  MI  U.S.’s 
minimum  required  assets  under 
the  PMIERs  will  be 
determined, in part, by the particular risk profiles of the loans 
it  insures.  If,  absent  other  changes,  Arch  MI  U.S.’s  mix  of 
business changes to include more loans with higher loan-to-
value  ratios  or  lower  credit  scores,  it  will  have  a  higher 
minimum  required  asset  amount  under  the  PMIERs  and, 
accordingly,  be  required  to  hold  more  capital  in  order  to 
maintain GSE eligibility. Our eligible mortgage insurers each 
satisfied the PMIERs’ financial requirements as of December 
31, 2023. While we intend to continue to comply with these 
requirements,  there  can  be  no  assurance  that  the  GSEs  will 
not  change  the  PMIERs  or  that  Arch  Mortgage  Insurance 
Company  or  United  Guaranty  Residential 
Insurance 
Company  will  continue  as  eligible  mortgage  insurers.  If 
either  or  both  of  the  GSEs  were  to  cease  to  consider  Arch 
Mortgage 
Insurance  Company  or  United  Guaranty 
Residential Insurance Company as eligible mortgage insurers 
and,  therefore,  cease  accepting  our  mortgage  insurance 
products,  our  results  of  operations  and  financial  condition 
would be adversely affected.

The  implementation  of  the  Basel  III  Capital  Accord  and 
FHFA’s  Enterprise  Regulator  Capital  Framework  may 
adversely  affect  the  use  of  mortgage  insurance  and  CRT 
opportunities.

With certain exceptions, the Basel III Rules became effective 
on January 1, 2014. In December 2017, the Basel Committee 
published final revisions to the Basel Capital Accord which is 
informally denominated in the U.S. as “Basel III Endgame.” 
The  Basel  Committee  expects  the  new  rules  to  be  fully 
implemented by January 2027.

On  July  27,  2023,  the  Federal  banking  agencies  released  a 
proposed  rule  to  implement  the  Basel  III  Endgame  in  the 
United States. The proposal would eliminate the capital relief 
currently  afforded  mortgage  loans  protected  by  private 
mortgage  insurance.  Instead,  the  capital  treatment  would  be 
based  on  the  mortgage’s  loan  to  value  ratio  without 
consideration  of  mortgage  insurance.  The  comment  period 
for  this  proposal  closed  on  January  16,  2024.  If  the  U.S. 
regulators  decide  to  adopt  the  proposed  Basel  III  Endgame 
approach  to  mortgage  assets,  the  capital  treatment  of 
mortgages held in portfolio will increase and the capital relief 
benefits  of  mortgage  insurance  would  be  eliminated,  which 
could adversely affect the volume of mortgages originated by 
banks  subject  to  the  rule  and  the  demand  for  mortgage 
insurance.

On  December  17,  2020,  the  FHFA  published  a  new 
Enterprise  Regulatory  Capital  Framework 
(“ERCF”) 
Enterprise Capital Rule for Fannie Mae and Freddie Mac that 
significantly  increases  minimum  capital  requirements  for 
these  GSEs.  The  new  rule  requires  each  GSE  to  maintain 
both  higher  minimum  capital  ratios  and  capital  “buffers”  to 
avoid  restrictions  on  capital  distributions  and  discretionary 
bonus payments. Changes were made to the ERCF in 2022 to 
incentive  CRT  transactions,  and  in  2023  to  address  capital 
requirements for derivatives; market risk; multifamily loans; 
and exposures of an Enterprise to the other Enterprise.

compliant  with  the  PMIERs.  The  amount  of  capital  relief 
afforded  for  mortgage  insurers  depends  on  a  number  of 
factors, 
the 
creditworthiness of the mortgage insurer, which could affect 
the competitive position of the individual mortgage insurance 
providers.  The  higher  risk-capital  charges  for  residential 
mortgages could be incorporated into the PMIERs standards, 
thereby  requiring  mortgage  insurers  to  hold  higher  capital 
levels  in  order  to  be  recognized  as  approved  counterparties 
for  the  GSEs.  This  could  have  a  negative  impact  on  our 
return on equity.

In  addition,  higher  capital  standards  could  impact  the 
guarantee  fees  charged  to  acquire  loans.  In  January  2023, 
after the Enterprises had fully transitioned to the new ERCF 
capital  regime,  FHFA  announced  new  pricing  matrices 
redesigned  and  recalibrated  to  align  the  fee  structure  more 
closely with the risk factors utilized in the capital framework. 
Future changes to the ERCF, or the guarantee fees charged to 
acquire  loans,  could  adversely  impact  credit  for  credit  risk 
transfer, the capital relief afforded mortgage insurance or the 
volume  of  loans  purchased  by  the  Enterprises  and  the 
demand for mortgage insurance.

Risk Relating to Our Company and Our Shares

Some of the provisions of our bye-laws and our shareholders 
agreement  may  have  the  effect  of  hindering,  delaying  or 
preventing  third  party  takeovers  or  changes  in  management 
initiated by shareholders. These provisions may also prevent 
our  shareholders  from  receiving  premium  prices  for  their 
shares in an unsolicited takeover.

Some  provisions  of  our  bye-laws  could  have  the  effect  of 
discouraging  unsolicited  takeover  bids  from  third  parties  or 
changes  in  management  initiated  by  shareholders.  These 
provisions may encourage companies interested in acquiring 
us  to  negotiate  in  advance  with  our  Board,  since  the  Board 
has  the  authority  to  overrule  the  operation  of  several  of  the 
limitations.

Among  other  things,  our  bye-laws  provide:  for  a  classified 
Board,  in  which  the  directors  of  the  class  elected  at  each 
annual general meeting holds office for a term of three years, 
with  the  term  of  each  class  expiring  at  successive  annual 
general  meetings  of  shareholders;  that  the  number  of 
directors is determined by the Board from time to time by a 
vote of the majority of the Board; that directors may only be 
removed  for  cause,  and  cause  removal  shall  be  deemed  to 
exist only if the director whose removal is proposed has been 
convicted of a felony or been found by a court to be liable for 
gross negligence or misconduct in the performance of his or 
her  duties;  that  the  Board  has  the  right  to  fill  vacancies, 
including  vacancies  created  by  an  expansion  of  the  Board; 
and for limitations on a shareholder’s right to raise proposals 
or  nominate  directors  at  general  meetings.  Our  bye-laws 
provide  that  certain  provisions  that  may  have  anti-takeover 
effects  may  be  repealed  or  altered  only  with  prior  Board 
approval  and  upon  the  affirmative  vote  of  holders  of  shares 
representing  at  least  65%  of  the  total  voting  power  of  our 
shares entitled generally to vote at an election of directors.

The  bye-laws  also  contain  a  provision  limiting  the  rights  of 
any  U.S.  person  (as  defined  in  section  7701(a)(30)  of  the 
Internal  Revenue  Code  of  1986,  as  amended  (the  “Code”)) 
that  owns  shares  of  Arch  Capital,  directly,  indirectly  or 
constructively  (within  the  meaning  of  section  958  of  the 
Code),  representing  more  than  9.9%  of  the  voting  power  of 
all shares entitled to vote generally at an election of directors. 
The votes conferred by such shares of such U.S. person will 
be reduced by whatever amount is necessary so that after any 
such  reduction  the  votes  conferred  by  the  shares  of  such 
person  will  constitute  9.9%  of  the  total  voting  power  of  all 
shares  entitled  to  vote  generally  at  an  election  of  directors. 
Notwithstanding  this  provision,  the  Board  may  make  such 
final adjustments to the aggregate number of votes conferred 
by the shares of any U.S. person that the Board considers fair 
and reasonable in all circumstances to ensure that such votes 
represent  9.9%  of  the  aggregate  voting  power  of  the  votes 
conferred  by  all  shares  of  Arch  Capital  entitled  to  vote

Arch  Capital  is  a  holding  company  whose  assets  primarily 
consist  of  the  shares  in  our  subsidiaries.  Generally,  Arch 
Capital  depends  on  its  available  cash  resources,  liquid 
investments  and  dividends  or  other  distributions  from 
subsidiaries to make payments, including the payment of debt 
service  obligations  and  operating  expenses  it  may  incur  and

liquidation amounts with respect to our preferred shares and 
common  shares,  and  to  fund  the  share  repurchase  program. 
The  ability  of  our  regulated  insurance  and  reinsurance

General  market  conditions  and  unpredictable  factors  could 
adversely affect market prices for our outstanding preferred 
shares.

There  can  be  no  assurance  about  the  market  prices  for  our 
series  of  preferred  shares  that  are  traded  publicly.  Several 
factors, many of which are beyond our control, will influence 
the  fair  value  of  our  preferred  shares,  including,  but  not

provided by any ratings agency have changed;

the market for similar securities; and

economic,  financial,  geopolitical,  social,  regulatory  or 
judicial  events  that  affect  us  and/or  the  insurance  or 
financial markets generally.

Dividends on our preferred shares are non-cumulative.

Dividends  on  our  preferred  shares  are  non-cumulative  and 
payable only out of lawfully available funds of Arch Capital 
under  Bermuda  law.  Consequently,  if  the  Board  (or  a  duly 
authorized  committee  of  the  Board)  does  not  authorize  and 
declare  a  dividend  for  any  dividend  period  with  respect  to 
any  series  of  our  preferred  shares,  holders  of  such  preferred 
shares  would  not  be  entitled  to  receive  any  such  dividend, 
and  such  unpaid  dividend  will  not  accrue  and  will  never  be 
payable.  Arch  Capital  will  have  no  obligation  to  pay 
dividends  for  a  dividend  period  on  or  after  the  dividend 
payment  date  for  such  period  if  the  Board  (or  a  duly 
authorized  committee  of  the  Board)  has  not  declared  such 
dividend  before  the  related  dividend  payment  date;  if 
dividends  on  our  series  F  or  series  G  preferred  shares  are 
authorized  and  declared  with  respect  to  any  subsequent 
dividend  period,  Arch  Capital  will  be  free  to  pay  dividends 
on  any  other  series  of  preferred  shares  and/or  our  common 
shares.  In  the  past,  we  have  not  paid  dividends  on  our 
common shares.

Our  preferred  shares  are  equity  and  are  subordinate  to  our 
existing and future indebtedness.

Our preferred shares are equity interests and do not constitute 
indebtedness. As such, these preferred shares will rank junior 
to  all  of  our  indebtedness  and  other  non-equity  claims  with 
respect to assets available to satisfy our claims, including in 
our  liquidation.  Our  existing  and  future  indebtedness  may

Risks Relating to Taxation

We  expect  to  become  subject  to  increased  taxation  in 
Bermuda  as  a  result  of  the  recently  adopted  Bermuda  CIT 
Act,  and  may  become  subject  to  increased  taxation  in  other 
countries  as  a  result  of  the  implementation  of  the  OECD's 
plan on “Base Erosion and Profit Shifting.”

The OECD, with the support of the G20, initiated the “Base 
Erosion  and  Profit  Shifting”  (“BEPS”)  project  in  2013  in 
response to concerns that changes are needed to international 
tax laws to address situations where multinationals may pay 
little or no tax in certain jurisdictions by shifting profits away 
from  jurisdictions  where  the  activities  creating  those  profits 
may  take  place.  In  November  2015,  “final  reports”  were 
approved  for  adoption  by  the  G20  finance  ministers.  The 
final reports provide the basis for international standards for 
corporate taxation that are designed to prevent, among other 
things, the artificial shifting of income to tax havens and low-
tax jurisdictions, the erosion of the tax base through interest 
deductions on intercompany debt and the artificial avoidance 
of  permanent  establishments  (i.e., 
tax  nexus  with  a 
jurisdiction).

implement 

to  adopt  and 

these  standards, 
Legislation 
including  country  by  country  reporting,  has  been  enacted  or 
is currently under consideration in a number of jurisdictions. 
As a result, our income may be taxed in jurisdictions where it 
is not currently taxed and at higher rates of tax than currently 
taxed, which may substantially increase our effective tax rate. 
Also, the continued adoption of these standards may increase 
the complexity and costs associated with tax compliance and 
adversely  affect  our  financial  position  and  results  of 
operations.

In May 2019, the OECD published a “Programme of Work,” 
divided into two pillars, which is designed to address the tax 
challenges  created  by  an  increasing  digitalized  economy. 
Pillar  I  addresses  the  broader  challenge  of  a  digitalized 
economy  and  focuses  on  the  allocation  of  group  profits 
among taxing jurisdictions based on a market-based concept 
rather than historical “permanent establishment” concepts. In 
January 2020, the OECD released a statement excluding most 
financial  services  activities,  including  insurance  activities, 
from the scope of the profit reallocation mechanism in Pillar 
I.  The  OECD  statement  cited  the  presence  of  commercial 
(rather  than  consumer)  customers  as  grounds  for  the  carve-
out, but also acknowledged that a “compelling case” could be 
made  that  the  consumer-facing  business  lines  of  insurance 
companies  should  be  excluded  from  the  scope  of  Pillar  I 
given  the  impact  of  regulations  and  licensing  requirements 
that typically ensure that residual profits are largely realized 
in 
from 
“unregulated  elements  of  the  financial  services  sector” 
remain in scope but only where revenue exceeds €20 billion.

Pillar II addresses the remaining BEPS risk of profit shifting 
to  certain  in-scope  entities  in  low  tax  jurisdictions  by 
introducing  a  global  minimum  tax  (15%),  which  would 
operate  through  a  denial  of  a  deduction  or  imposition  of 
source-based  taxation  (including  withholding  tax)  on  certain 
payments. In calculating whether the effective tax rate of an 
in-scope entity meets the minimum tax rate, certain deferred 
income tax assets and liabilities reflected or disclosed in the 
financial  accounts  of  an  in-scope  entity  are  taken  into 
account. In October 2021, 136 jurisdictions agreed on a two-
pillar solution to address the tax challenges arising from the 
digitalization of the economy. In December 2021, the OECD 
released  Model  Rules  for  implementation  of  Pillar  II 
followed  by  the  release  of  detailed  commentary  in  March 
2022.  The  OECD  has  released  additional  administrative 
guidance  on  the  global  minimum  tax  in  February,  July  and 
December  of  2023.  Under  the  European  Union’s  minimum 
tax  directive,  unanimously  agreed  by  the  member  states  in 
2022,  each  member  state  is  required  to  adopt  domestic 
legislation implementing the minimum tax rules effective for 
periods  beginning  on  or  after  December  31,  2023,  with  the 
“under-taxed profit rule” to take effect for periods beginning 
on  or  after  December  31,  2024.  Legislatures  in  multiple 
countries  outside  of  the  European  Union  have  also  drafted 
and/or  enacted 
the  OECD’s 
to 
minimum tax proposal. Given the OECD's continued release 
of guidance regarding Pillar II, that only certain jurisdictions 
have currently enacted laws to give effect to Pillar II, and that 
jurisdictions  may  interpret  such  laws  in  different  manners, 
the overall implementation of Pillar II remains uncertain and 
subject to change, possibly on a retroactive basis.

On  August  8,  2023,  the  Bermuda  Ministry  of  Finance 
published  its  first  Public  Consultation  announcing  the 
proposed  implementation  of  a  new  corporate  income  tax 
regime  applicable  to  Bermuda  businesses  that  are  part  of 
Multinational Enterprise Groups with annual revenue of €750 
million  or  more.  A  Second  Public  Consultation  was 
published  on  October  5,  2023  confirming,  inter  alia,  a 
statutory  corporate  tax  rate  of  15%  and  a  Third  Public 
Consultation  was  published  on  November  15,  2023.  The 
Bermuda CIT Act was enacted on December 27, 2023 and is 
to be effective for tax years beginning on or after January 1, 
2025.  The  Bermuda  Government  announced  in  its  Second 
Public Consultation that any new Bermuda corporate income 
tax  regime  would  supersede  existing  Tax  Assurance 
Certificates  held  by  entities  within  the  scope  of  the  new 
Bermuda  corporate  income  tax  (such  as  those  issued  to  us, 
referred  to  above  under  “—Taxation  of  Arch  Capital. 
Bermuda.”).  Given  the  potential  for  the  new  Bermuda 
corporate  income  tax  to  supersede  existing  Tax  Assurance 
Certificates, it is likely that Arch will be subject to Bermuda 
tax for tax years beginning on or after January 1, 2025.

The  adoption  of  the  tax  laws  described  above  (in  particular, 
the  adoption  of  an  “under-taxed  profit  rule”  by  certain 
countries in which we and our affiliates do business and the 
expected implementation of a corporate income tax regime in 
Bermuda)  are  expected  to  result  in  an  increase  to  our 
effective  tax  rate  and  aggregate  tax  liability,  which  may 
adversely  affect  our  financial  position  and  results  of 
operations,  and  is  expected  to  increase  the  complexity  and 
cost  of  our  worldwide  tax  compliance.  Although  certain 
jurisdictions in which we and our affiliates do business have 
enacted  an  “under-taxed  profit  rule”,  such  rule  is  only 
expected  to  take  effect  for  taxable  periods  beginning  on  or 
after December 31, 2024. Such tax laws may not be enacted 
or the form of such tax laws could change on a prospective or 
retroactive  basis.  The  impact  of  any  such  changes  is 
unknown, but such changes could have an adverse effect on 
our  effective  tax  rate  and  aggregate  tax  liability  and  could 
increase  the  complexity  and  costs  associated  with  our  tax 
compliance worldwide.

ITEM 1C. CYBERSECURITY

Risk management and strategy 

We  prioritize  the  management  of  cybersecurity  risk  and  the 
protection of information across our enterprise by embedding 
data  protection  and  cybersecurity  risk  management  in  our 
operations.  Our  processes  for  assessing,  identifying,  and 
managing material risks from cybersecurity threats have been 
integrated  into  our  overall  risk  management  system  and 
processes.  For  example,  to  identify  and  assess  risks  from 
cybersecurity 
threats,  our  enterprise  risk  management 
program  considers  cybersecurity  as  part  of  the  Company’s 
risk assessment process, and our risk management framework 
to  monitor  key  risks  such  as 
requires  risk  owners 
cybersecurity on a continuous basis. See Item 1, “Business—
Enterprise Risk Management” for additional information. 

As  a  foundation  of  our  approach  to  cybersecurity  risk,  we 
have  implemented  processes  at  several  levels  across  our 
enterprise  to  help  assess,  identify  and  manage  cybersecurity 
risks.  Our  privacy  and  information  security  policies  and 
standards  govern  our  business  lines  and  subsidiaries  and 
encompass  incident  response,  access  control,  and  vendor 
management,  among  others.  In  order  to  develop  these 
policies  and  procedures,  we  monitor  the  privacy  and 
cybersecurity laws, regulations and guidance applicable to us 
in the regions where we do business. See Item 1, “Business—
Regulation—Cybersecurity  and  Privacy”  for  additional 
details. 

We annually undergo an external evaluation by a third party 
cybersecurity firm with a specialty in penetration testing. Our 
vendor management group performs information security risk 
assessments on our third party service providers with respect 
to their ability to protect data from unauthorized access, and 
on  a  risk  weighted  basis,  we  perform  re-assessments 
routinely.  The  Company  also  requires  these  vendors  to 
adhere to privacy and cybersecurity measures and has a third 
party  service  provider  monitoring  program  in  place  that 
reviews changes to the security posture of certain higher risk 
third  party  service  providers.  In  addition,  the  Company 
negotiates  appropriately  protective 
legal 
agreements with these providers.

Our  operations  rely  on  the  secure  processing,  storage  and 
transmission  of  confidential  and  other  information  in  our 
computer systems and networks. Computer viruses, hackers, 

employee  or  vendor  error  or  misconduct,  and  other  external 
hazards  could  expose  our  information  systems  and  those  of 
our  vendors  to  security  breaches,  cybersecurity  incidents  or 
other  disruptions,  any  of  which  could  materially  and 
adversely affect our ability to conduct our business. While we 
and third parties with which we do business have experienced 
cybersecurity  incidents,  to  date,  the  Company  does  not 
believe  that  any  previous  cybersecurity  incidents  have 
materially affected the Company. 

The sophistication of cybersecurity threats, including through 
the  use  of  AI,  continues  to  increase,  and  the  controls  and 
preventative  actions  that  we  take  to  reduce  the  risk  of 
cybersecurity incidents and protect our systems, including the 
regular  testing  of  our  cybersecurity  incident  response  plan, 
may  be  insufficient.  In  addition,  new  technology  that  could 
result in greater operational efficiency such as AI may further 
expose  our  information  systems  to  the  risk  of  cybersecurity 
incidents. See Item 1A, “Risk Factors—Risk Relating to Our 
Industry,  Business  &  Operations—Technology  failures  and 
cyber  attacks,  including,  but  not  limited  to,  ransomware, 
exploitation in software or code with malicious intent, state-

new  technologies,  such  as  generative  AI,  may  impact  us  or 
our  business  partners  and  service  providers,  causing  a

OVERVIEW

CURRENT OUTLOOK

Arch  Capital  Group  Ltd.  (“Arch  Capital”  and,  together  with 
its  subsidiaries,  “we”  or  “us”)  is  a  publicly  listed  Bermuda 
exempted  company  with  approximately  $21.1  billion  in 
capital  at  December  31,  2023  and  is  part  of  the  S&P  500 
index.  Through  operations  in  Bermuda,  the  United  States, 
United  Kingdom,  Europe,  Canada  and  Australia,  we  write 
specialty  lines  of  property  and  casualty  insurance  and 
reinsurance,  as  well  as  mortgage  insurance  and  reinsurance, 
on  a  worldwide  basis.  It  is  our  belief  that  our  underwriting 
platform,  experienced  management  team  and  strong  capital 
base  enable  us  to  establish  a  strong  presence  in  the  markets 
where we operate.

The  worldwide  property  casualty  insurance  and  reinsurance 
industry  is  highly  competitive  and  has  traditionally  been 
subject  to  an  underwriting  cycle.  In  that  cycle,  a  “hard” 
market  is  evidenced  by  high  premium  rates,  restrictive 
underwriting  standards,  narrow  terms  and  conditions,  and 
strong  underwriting  profits  for  insurers.  A  “hard”  market 
typically attracts new capital and new entrants to the market 
and  is  eventually  followed  by  a  “soft”  market,  which  has 
characteristics  of  low  premium  rates,  relaxed  underwriting 
standards,  broader 
lower 
underwriting  profits  for  insurers.  Market  conditions  in  the 
property and casualty arena may affect, among other things, 
the demand for our products, our ability to increase premium 
rates,  the  terms  and  conditions  of  the  insurance  policies  we 
write, changes in the products offered by us or changes in our 
business strategy.

terms  and  conditions,  and 

The  financial  results  of  the  property  casualty  insurance  and 
reinsurance  industry  are  influenced  by  factors  such  as  the 
frequency  and/or  severity  of  claims  and  losses,  including 
natural  disasters  or  other  catastrophic  events,  variations  in 
interest  rates  and  financial  markets,  changes  in  the  legal, 
regulatory  and  judicial  environments,  inflationary  pressures 
and  general  economic  conditions.  These  factors  influence, 
among other things, the demand for insurance or reinsurance, 
the supply of which is generally related to the total capital of 
competitors in the market.

Mortgage  insurance  and  reinsurance  are  subject  to  similar 
cycles to property casualty except that they have historically 
been more dependent on macroeconomic conditions.

As we conclude another record year and head into 2024, our 
objective remains the same, to deliver long term value for our 
shareholders. With our commitment to underwriting acumen, 
prudent  reserving  and  cycle-focused  capital  allocation,  we 
were  able  to  deliver  another  profitable  year.  Our  full  year 
financial  performance  was  excellent,  with  an  annualized  net 
income  and  operating  returns  on  average  common  equity  of 
29.7%  and  21.6%,  respectively.  See  “Comment  on  Non-
GAAP Financial Measures.”

We  continue  to  execute  our  cycle  management  strategy  by 
actively  allocating  capital  to  the  segments  with  the  best  risk 
adjusted returns. Growth was strong all year in our property 
and casualty segments which wrote over $17 billion of gross 
premium  written  and  over  $12.4  billion  of  net  premium 
written,  and,  while  most  current  growth  opportunities  are  in 
the property and casualty sector, it is important to recognize 
the  steady  and  quality  underwriting  performance  of  our 
mortgage  group.  Although  mortgage  market  conditions 
meant fewer opportunities for top line growth, the mortgage 
segment  continued  to  generate  significant  profits  totaling 
nearly $1.1 billion of underwriting income for the year. 

At  Arch,  our  primary  focus  has  always  been  on  rate 
adequacy, regardless of market conditions. Our underwriting 
culture dictates that we include a meaningful margin of safety 
in  our  pricing,  especially  in  softer  conditions  and  take  a 
longer  term  view  of  inflation  and  rates.  As  underwriting 
opportunities  arise,  our  reinsurance  segment  is  able  to  react 
quickly  and  significantly  when  markets  pivot.  In  the 
reinsurance property market, our overall exposure to property 
catastrophe  risk  remains  well  below  our  self  imposed 
threshold  (see  “Catastrophic  and  Severe  Economic  Events”) 
and,  because  of  our  diversified  portfolio  and  broad  set  of 
opportunities,  we  retain  the  flexibility  to  pursue  the  most 
attractive  returns  across  lines  and  geographies.  The  hard 
market  conditions  remained  elevated  in  several  lines  during 
the January 1, 2024 renewal cycle. 

In  our  insurance  segment,  we  continue  to  take  advantage  of 
favorable  global  market  conditions  with  net  premiums 
written  up  17%  in  2023.  Although  pricing  has  declined  in 
some lines, such as large public directors and officers liability 
insurance,  the  markets  in  which  our  insurance  segment 
operates  generally  continue  to  provide  adequate  returns.  In 
2023,  the  most  notable  gains  came  in  property,  marine, 
construction and national accounts.

Inflation  continues  to  be  a  focus  for  our  industry.  We 
proactively  analyze  available  data  and  we  incorporate 
emerging  trends  into  our  pricing  and  reserving.  We  believe 
that 
in  future 
investment  returns  and  prudent  reserving,  allows  us  to 
maximize the capabilities of our diversified platform.

this  discipline,  coupled  with 

increases 

Our mortgage segment continues to deliver a steady level of 
earnings  for  our  shareholders.  Higher  persistency  of  our  in 
force  U.S.  primary  mortgage  insurance  portfolio  helped 
offset  the  significant  industry  wide  reduction  in  mortgage 
originations  in  2023.  The  credit  profile  of  our  U.S.  primary 
mortgage  insurance  portfolio  remains  excellent  and  the 
overall  mortgage  market  continues  to  be  disciplined  and 
return focused. We continue to see meaningful opportunities 
for  the  mortgage  segment  outside  of  the  U.S.  and  our 
strategic  decision  to  diversify  our  mortgage  operations  is 
yielding positive results.

FINANCIAL MEASURES

Management uses the following three key financial indicators 
in  evaluating  our  performance  and  measuring  the  overall 
growth  in  value  generated  for  Arch  Capital’s  common 
shareholders:

Book Value per Share

is 

and 

common 

Book value per share represents total common shareholders’ 
equity  available  to  Arch  divided  by  the  number  of  common 
shares 
equivalents  outstanding. 
share 
Management  uses  growth  in  book  value  per  share  as  a  key 
measure of the value generated for our common shareholders 
each period and believes that book value per share is the key 
driver  of  Arch  Capital’s  share  price  over  time.  Book  value 
per  share 
impacted  by,  among  other  factors,  our 
underwriting results, investment returns and share repurchase 
activity,  which  has  an  accretive  or  dilutive  impact  on  book 
value per share depending on the purchase price. Book value 
per  share  was  $46.94  at  December  31,  2023,  a  43.9% 
increase from $32.62 at December 31, 2022. The increase in 
book  value  per  share  in  2023  reflected  strong  underwriting 
and investment results and also reflected the establishment of 
a net deferred income tax asset of $1.18 billion, or $3.16 per 
share,  related  to  the  enactment  of  Bermuda’s  new  corporate 
income tax. 

Operating Return on Average Common Equity

Operating  return  on  average  common  equity  (“Operating 
ROAE”)  represents  annualized  after-tax  operating  income 
available  to  Arch  common  shareholders  divided  by  average 
common  shareholders’  equity  available  to  Arch  during  the 
to  Arch 
period.  After-tax  operating 
common shareholders, a “non-GAAP measure” as defined in 
the  SEC  rules,  represents  net  income  available  to  Arch 
common shareholders, excluding net realized gains or losses

income 

Our annualized net income return on average common equity 
was  29.7%  for  2023,  compared  to  11.6%  for  2022.  Our 
Operating  ROAE  was  21.6%  for  2023,  compared  to  14.8% 
for  2022,  with  the  higher  return  in  2023  primarily  resulting 
from  improved  underwriting  results  and  growth  in  net 
investment income.

Total Return on Investments

Total  return  on  investments  includes  investment  income, 
equity  in  net  income  or  loss  of  investments  accounted  for 
using the equity method, net realized gains or losses and the 
change  in  unrealized  gains  or  losses  generated  by  Arch’s 
investment  portfolio.  Total  return  is  calculated  on  a  pre-tax 
basis  before 
investment  expenses,  excluding  amounts 
reflected  in  the  ‘other’  segment,  and  reflects  the  effect  of 
financial  market  conditions  along  with  foreign  currency 
fluctuations. Management uses total return on investments as 
a  key  measure  of  the  return  generated  for  Arch  common 
shareholders  on  the  capital  held  in  the  business,  and 
compares  the  return  generated  by  our  investment  portfolio 
against  benchmark  returns.  See  “Comment  on  Non-GAAP 
Financial Measures.” 

The  following  table  summarizes  the  pre-tax  total  return 
(before  investment  expenses)  of  investments  held  by  Arch 
compared  to  the  benchmark  return  (both  based  in  U.S. 
Dollars) against which we measured our portfolio during the 
periods:

(1)  Our  investment  expenses  were  approximately  0.26%  and  0.28%, 
respectively, of average invested assets in 2023 and 2022.

Total return for 2023 reflected strong returns in fixed income, 
equity  and  alternative  strategies.  Actual  performance  trailed 
the benchmark return for the year, largely due to the portfolio 
being  underweight  risk  assets  compared  to  the  benchmark. 
We  continue  to  maintain  a  relatively  short  duration  on  our 
portfolio of 2.91 years at December 31, 2023.

The benchmark return index is a customized combination of 
indices  intended  to  approximate  a  target  portfolio  by  asset 
mix  and  average  credit  quality  while  also  matching  the 
approximate  estimated  duration  and  currency  mix  of  our 
insurance and reinsurance liabilities. Although the estimated 
duration and average credit quality of this index will move as 
the  duration  and  rating  of  its  constituent  securities  change, 
generally we do not adjust the composition of the benchmark 
return  index  except  to  incorporate  changes  to  the  mix  of 
liability  currencies  and  durations  noted  above.  The 
benchmark  return 
interpreted  as 
expressing  a  preference  for  or  aversion  to  any  particular 
sector  or  sector  weight.  The  index  is  intended  solely  to 
provide, unlike many master indices that change based on the 
size of their constituent indices, a relatively stable basket of 
investable  indices.  At  December  31,  2023,  the  benchmark 
return  index  had  an  average  credit  quality  of  “A1”  by 
Moody’s, an estimated duration of 2.64 years.

COMMENT ON NON-GAAP FINANCIAL MEASURES

Throughout this filing, we present our operations in the way 
we  believe  will  be  the  most  meaningful  and  useful  to 
investors,  analysts,  rating  agencies  and  others  who  use  our 
financial  information  in  evaluating  the  performance  of  our 
company.  This  presentation  includes  the  use  of  after-tax 
operating  income  available  to  Arch  common  shareholders, 
which  is  defined  as  net  income  available  to  Arch  common 
shareholders,  excluding  net  realized  gains  or  losses  (which 
includes  changes  in  the  allowance  for  credit  losses  on 
financial  assets  and  net  impairment  losses  recognized  in 
earnings),  equity  in  net  income  or  loss  of  investments 
accounted for using the equity method, net foreign exchange 

gains  or  losses,  transaction  costs  and  other,  net  of  income 
taxes (which for the 2023 fourth quarter includes a one-time 
deferred  income  tax  benefit  related  to  the  enactment  of 
Bermuda’s  new  corporate  income  tax),  and  the  use  of 
annualized operating return on average common equity. The 
presentation  of  after-tax  operating  income  available  to  Arch 
common  shareholders  and  annualized  operating  return  on 
average common equity are non-GAAP financial measures as 
defined in Regulation G. The reconciliation of such measures 
to  net  income  available  to  Arch  common  shareholders  and 
annualized net income return on average common equity (the 
most  directly  comparable  GAAP  financial  measures)  in 
accordance with Regulation G is included under “Results of 
Operations” below.

We  believe  that  net  realized  gains  or  losses,  equity  in  net 
income or loss of investments accounted for using the equity 
method, net foreign exchange gains or losses and transaction 
costs and other in any particular period are not indicative of 
the performance of, or trends in, our business. Although net 
realized  gains  or  losses,  equity  in  net  income  or  loss  of 
investments  accounted  for  using  the  equity  method  and  net 
foreign  exchange  gains  or  losses  are  an  integral  part  of  our 
operations, the decision to realize these items are independent 
of  the  insurance  underwriting  process  and  result,  in  large 
part, from general economic and financial market conditions. 
Furthermore,  certain  users  of  our  financial  information 
believe  that,  for  many  companies,  the  timing  of  the 
realization  of 
largely 
opportunistic. In addition, changes in the allowance for credit 
losses  and  net  impairment  losses  recognized  in  earnings  on 
the  Company’s  investments  represent  other-than-temporary 
declines  in  expected  recovery  values  on  securities  without 
actual realization.

The use of the equity method on certain of our investments in 
certain funds that invest in fixed maturity securities is driven 
by  the  ownership  structure  of  such  funds  (either  limited 
partnerships  or  limited  liability  companies).  In  applying  the 
equity method, these investments are initially recorded at cost 
and  are  subsequently  adjusted  based  on  our  proportionate

changes  in  the  market  value  of  the  underlying  securities  in

way we account for our other investments and the timing of 
the recognition of equity in net income or loss of investments 
accounted for using the equity method may differ from gains 
or  losses  in  the  future  upon  sale  or  maturity  of  such 
investments.

are  not  indicative  of  the  performance  of,  or  trends  in,  our

In  the  2023  fourth  quarter,  the  Company  established  a  net 
deferred  income  tax  asset,  resulting  in  a  benefit  of  $1.18 
billion,  consistent  with  the  transition  provisions  specified  in 
the Bermuda CIT Act. Due to the non-recurring nature of this 
one-time item, the Company believes that excluding this item 
from after-tax operating income or loss available to common 
shareholders provides the user with a better evaluation of the 
Company’s ongoing business performance.

income  available 

We  believe  that  showing  net  income  available  to  Arch 
common  shareholders  exclusive  of  the  items  referred  to 
above  reflects  the  underlying  fundamentals  of  our  business 
since  we  evaluate  the  performance  of  and  manage  our 
business  to  produce  an  underwriting  profit.  In  addition  to 
to  Arch  common 
presenting  net 
shareholders,  we  believe  that  this  presentation  enables 
investors  and  other  users  of  our  financial  information  to 
analyze  our  performance  in  a  manner  similar  to  how 
management analyzes performance. We also believe that this 
measure  follows  industry  practice  and,  therefore,  allows  the 
users  of  financial  information  to  compare  our  performance 
with  our  industry  peer  group.  We  believe  that  the  equity 
analysts  and  certain  rating  agencies  that  follow  us  and  the 
insurance  industry  as  a  whole  generally  exclude  these  items 
from their analyses for the same reasons.

in  note  4,  “Segment  Information,” 
they  are

considered  non-GAAP  financial  measures  when  presented

in  Item  8, 

We measure segment performance for our three underwriting 
segments  based  on  underwriting  income  or  loss.  We  do  not 
manage  our  assets  by  underwriting  segment,  with  the 
exception of goodwill and intangible assets, and, accordingly, 
investment  income,  income  from  operating  affiliates  and 
other non-underwriting related items are not allocated to each 
underwriting segment. 

income  or 

loss  before 

Along with consolidated underwriting income, we provide a 
the 
subtotal  of  underwriting 
contribution  from  the  ‘other’  segment.  Through  June  30, 
2021,  the  ‘other’  segment  included  the  results  of  Somers 
Holdings  Ltd.  (formerly  Watford  Holdings  Ltd.).  Somers 
Holdings  Ltd.  is  the  parent  of  Somers  Re  Ltd.,  a  multi-line 
Bermuda  reinsurance  company  (together  with  Somers 
Holdings  Ltd.,  “Somers”).  Pursuant  to  GAAP,  Somers  was 
considered  a  variable  interest  entity  and  we  concluded  that 
we  were  the  primary  beneficiary  of  Somers.  As  such,  we 
consolidated  the  results  of  Somers  in  our  consolidated 
financial  statements  through  June  30,  2021.  In  the  2020 
fourth quarter, Arch Capital, Somers, and Greysbridge Ltd., a 
wholly-owned  subsidiary  of  Arch  Capital,  entered  into  an 
Agreement  and  Plan  of  Merger  (as  amended,  the  “Merger 
Agreement”).  Arch  Capital  assigned  its  rights  under  the 
Merger  Agreement 
to  Greysbridge  Holdings  Ltd. 
(“Greysbridge”).  The  merger  and  the  related  Greysbridge 
equity  financing  closed  on  July  1,  2021.  Effective  July  1, 
2021,  Somers 
is  wholly  owned  by  Greysbridge,  and 
Greysbridge  is  owned  40%  by  Arch  and  30%  by  certain 
funds managed by Kelso and 30% by certain funds managed 
the  governing  documents  of 
by  Warburg.  Based  on 
Greysbridge,  we  concluded  that,  while  we  retain  significant 
influence  over  Greysbridge,  Greysbridge  does  not  constitute 
a variable interest entity. Accordingly, effective July 1, 2021, 
we  no  longer  consolidate  the  results  of  Somers  in  our 
consolidated financial statements and footnotes. See note 12, 
“Variable Interest Entities and Noncontrolling Interests” and 
note 4, “Segment Information,” to our consolidated financial 
statements for additional information on Somers.

Our presentation of segment information includes the use of a 
current  year  loss  ratio  which  excludes  favorable  or  adverse 
development  in  prior  year  loss  reserves.  This  ratio  is  a  non-
GAAP  financial  measure  as  defined  in  Regulation  G.  The 
reconciliation  of  such  measure  to  the  loss  ratio  (the  most 
directly comparable GAAP financial measure) in accordance 
with Regulation G is shown on the individual segment pages. 
Management utilizes the current year loss ratio in its analysis 
of the underwriting performance of each of our underwriting 
segments.

Total  return  on  investments  includes  investment  income, 
equity  in  net  income  or  loss  of  investments  accounted  for 
using  the  equity  method,  net  realized  gains  or  losses 
(excluding changes in the allowance for credit losses on non-
investment  related  financial  assets)  and  the  change  in 
unrealized  gains  or  losses  generated  by  Arch’s  investment 
portfolio.  Total  return  is  calculated  on  a  pre-tax  basis  and 
before  investment  expenses,  excludes  amounts  reflected  in 
the ‘other’ segment, and reflects the effect of financial market 
conditions  along  with  foreign  currency  fluctuations.  In 
addition,  total  return  incorporates  the  timing  of  investment 
returns  during  the  periods.  There  is  no  directly  comparable 
GAAP  financial  measure  for  total  return.  Management  uses

generated  to  Arch  common  shareholders  on  the  capital  held

investment  portfolio  against  benchmark  returns  which  we 
measured our portfolio against during the periods.

Segment Information

We classify our businesses into three underwriting segments 
–  insurance,  reinsurance  and  mortgage  –  and  two  operating 
segments – corporate and ‘other.’ Our insurance, reinsurance 
and  mortgage  segments  each  have  managers  who  are 
responsible  for  the  overall  profitability  of  their  respective 
segments  and  who  are  directly  accountable  to  our  chief 
operating  decision  makers,  the  Chief  Executive  Officer  of 
Arch  Capital,  the  Chief  Financial  Officer  and  Treasurer  of 
Arch  Capital  and  the  President  and  Chief  Underwriting 
Officer of Arch Capital. The chief operating decision makers 
do not assess performance, measure return on equity or make 
resource  allocation  decisions  on  a  line  of  business  basis. 
Management  measures  segment  performance  for  our  three 
underwriting segments based on underwriting income or loss. 
We do not manage our assets by underwriting segment, with 
the  exception  of  goodwill  and 
intangible  assets  and 
accordingly,  investment  income  is  not  allocated  to  each 
underwriting segment.

segments  using 

We  determined  our 
the 
reportable 
management  approach  described  in  accounting  guidance 
regarding  disclosures  about  segments  of  an  enterprise  and 
related information. The accounting policies of the segments 
are  the  same  as  those  used  for  the  preparation  of  our 
consolidated  financial  statements.  Intersegment  business  is 
allocated  to  the  segment  accountable  for  the  underwriting 
results.

Net premiums written by the insurance segment were 16.7% 
higher  in  2023  than  in  2022.  The  increase  in  net  premiums 
written reflected growth in most lines of business, primarily 
due to rate increases, new business opportunities and growth 
in existing accounts.

The  insurance  segment’s  current  year  loss  ratio  was  3.5 
points  lower  in  2023  than  in  2022.  The  2023  loss  ratio 
included 2.7 points of current year catastrophic event activity, 
spread across series of global events, compared to 5.2 points 
in  2022,  primarily  related  to  Hurricane  Ian  and  a  series  of 
global events. The balance of the change in the 2023 current 
year  loss  ratio  resulted,  in  part,  from  the  effect  of  rate 
increases,  changes  in  mix  of  business  and  the  level  of 
attritional losses.

Prior Period Reserve Development.

The insurance segment’s net favorable development was $42 
million, or 0.8 points, for 2023, compared to $25 million, or 
0.6  points,  for  2022.  See  note  5,  “Reserve  for  Losses  and

Underwriting Expenses. 

The  insurance  segment’s  underwriting  expense  ratio  was

Underwriting Expenses.

The  underwriting  expense  ratio  for  the  reinsurance  segment 
was  26.1%  in  2023,  compared  to  27.3%  in  2022,  with  the 
decrease  primarily  due  to  growth  in  net  premiums  earned. 
The  2022  ratio  also  reflected  a  lower  level  of  contingent 
commissions  on  ceded  business,  primarily  due  to  Hurricane 
Ian.

The  persistency  rate  of  the  U.S.  primary  portfolio  of 
mortgage loans was 83.6% at December 31, 2023 compared 
to 79.5% at December 31, 2022, with the increase primarily 
reflecting a lower level of refinancing activity due to a higher 
interest rate environment. The persistency rate represents the 
percentage of mortgage insurance in force at the beginning of 
a  12-month  period  that  remains  in  force  at  the  end  of  such 
period.

Net  premiums  written  for  2023  were  7.1%  lower  than  in 
2022.  The  reduction  in  net  premiums  written  primarily 
reflected  lower  levels  of  mortgage  originations  in  the 
Australian  market  and  a  decrease  in  U.S.  primary  mortgage 
insurance  business,  which  was  partially  offset  by  a  higher 
volume  of  credit  risk  transfer  transactions.  Premiums  ceded 
for 2023 reflected $17 million of one-time payments related 
to the termination of eight Bellemeade agreements.

Other Underwriting Income.

Other  underwriting  income,  which  is  primarily  related  to 
GSE  risk-sharing 
transactions  services  and  our  whole 
mortgage  loan  purchase  and  sell  program,  was  $14  million 
for 2023, compared to $8 million for 2022.

Unlike property and casualty business for which we estimate 
ultimate  losses  on  premiums  earned,  losses  on  U.S.  primary 
mortgage insurance business are only recorded at the time a 
borrower is delinquent on their mortgage, in accordance with 
primary  mortgage  insurance  industry  practice.  Because  our 
primary  mortgage  insurance  reserving  process  does  not  take 
into  account  the  impact  of  future  losses  from  loans  that  are 
not  delinquent,  mortgage  insurance  loss  reserves  are  not  an 
estimate  of  ultimate  losses.  In  addition  to  establishing  loss 
reserves for delinquent loans, under GAAP, we are required 
to  establish  a  premium  deficiency  reserve  for  our  mortgage 
insurance  products  if  the  amount  of  expected  future  losses 
and  maintenance  costs  exceeds  expected  future  premiums, 
existing  reserves  and  the  anticipated  investment  income  for

such  product.  We  assess  the  need  for  a  premium  deficiency 
reserve  on  a  quarterly  basis  and  perform  a  full  analysis 
annually.  No  such  reserve  was  established  during  2023  or 
2022.

Current Year Loss Ratio.

The mortgage segment’s current year loss ratio was 1.0 point 
higher  in  2023  compared  to  2022.  The  higher  current  year 
loss ratio for 2023 reflected an increase in new delinquencies. 
The percentage of loans in default on U.S. primary mortgage 
insurance  decreased  from  1.77%  at  December  31,  2022  to 
1.74% at December 31, 2023. 

We  insure  mortgages  for  homes  in  areas  that  have  been 
impacted  by  catastrophic  events.  Generally,  mortgage 
insurance  losses  occur  only  when  a  credit  event  occurs  and, 
following  a  physical  damage  event,  when  the  home  is 
restored to pre-storm condition. Our ultimate claims exposure 
will  depend  on  the  number  of  delinquency  notices  received 
and  the  ultimate  claim  rate  related  to  such  notices.  In  the 
event  of  natural  disasters,  cure  rates  are  influenced  by  the 
adequacy  of  homeowners  and  flood  insurance  carried  on  a 
related  property,  and  a  borrower's  access  to  aid  from 
government entities and private organizations, in addition to 
other factors which generally impact cure rates in unaffected 
areas.

Prior Period Reserve Development.

The  mortgage  segment’s  net  favorable  development  was 
$344  million,  or  29.7  points,  for  2023,  compared  to  $554 
million,  or  47.8  points,  for  2022.  See  note  5,  “Reserve  for 
Losses and Loss Adjustment Expenses,” to our consolidated 
financial  statements  in  Item  8  for  information  about  the 
mortgage segment’s prior year reserve development.

Underwriting Expenses.

The  underwriting  expense  ratio  for  the  mortgage  segment 
was 18.2% for 2023, compared to 20.3% for 2022, with the 
decrease  primarily  due 
level  of  profit

Corporate Segment

The corporate segment results include net investment income, 
net  realized  gains  or  losses,  equity  in  net  income  or  loss  of 
investments  accounted  for  using  the  equity  method,  other 
income  (loss),  corporate  expenses,  transaction  costs  and 
other, amortization of intangible assets, interest expense, net 
foreign exchange gains or losses, income taxes items (which 
for  2023  reflects  the  establishment  of  a  net  deferred  income 
tax  asset  related  to  the  enactment  of  Bermuda’s  new 
corporate  income  tax),  income  from  operating  affiliates  and 
items related to our non-cumulative preferred shares.

Net Investment Income.

Investment  expenses  were  approximately  0.26%  of  average  invested 
assets for 2023, compared to 0.28% for 2022.

The  pre-tax  investment  income  yield  was  3.53%  for  2023, 
compared  to  1.99%  for  2022.  The  growth  in  net  investment 
income for 2023 compared to 2022 primarily reflected higher 
yields available in the financial markets. Net cash flow from 
operating  activities  contributed  $5.7  billion  in  2023,  which 
increased  our  invested  asset  base  and  contributed  to  the 
growth  in  net  investment  income.  The  pre-tax  investment 
income  yields  were  calculated  based  on  amortized  cost. 
Yields  on  future  investment  income  may  vary  based  on 
financial  market  conditions,  investment  allocation  decisions 
and other factors.

Net Realized Gains or Losses. 

We  recorded  net  realized  losses  of  $165  million  for  2023, 
compared  to  net  realized  losses  of  $663  million  for  2022. 
Currently,  our  portfolio  is  actively  managed  to  maximize 
total  return  within  certain  guidelines.  The  effect  of  financial 
market  movements  on  the  investment  portfolio  will  directly 
impact  net  realized  gains  or  losses  as  the  portfolio  is 
rebalanced. Net realized gains or losses from the sale of fixed 
maturities  primarily  results  from  our  decisions  to  reduce 
credit  exposure,  to  change  duration  targets,  to  rebalance  our 
portfolios or due to relative value determinations.

Interest Expense. 

Interest  expense  was  $133  million  for  2023,  compared  to 
$131  million  for  2022.  Interest  expense  primarily  reflects 
amounts related to our outstanding senior notes. 

Net Foreign Exchange Gains or Losses. 

Net  foreign  exchange  losses  for  2023  were  $60  million, 
compared  to  net  foreign  exchange  gains  for  2022  of  $102 
million.  Amounts  in  such  periods  were  primarily  unrealized 
and  resulted  from  the  effects  of  revaluing  our  net  insurance 
liabilities required to be settled in foreign currencies at each 
balance sheet date.

Income Tax Expense. 

Our  income  tax  provision  on  income  before  income  taxes 
resulted  in  a  benefit  of  24.5%  for  2023,  compared  to  an 
expense  of  5.1%  for  2022.  The  2023  provision  reflected  the 
establishment  of  a  net  deferred  income  tax  asset  of  $1.18 
billion related to the enactment of Bermuda’s new corporate 
income tax. Our effective tax rate fluctuates from year to year 
consistent with the relative mix of income or loss reported by 
jurisdiction and the varying tax rates in each jurisdiction. 

See  note  15,  “Income  Taxes,”  to  our  consolidated  financial 
statements  in  Item  8  for  a  reconciliation  of  the  difference 
between the provision for income taxes and the expected tax 
provision at the weighted average statutory tax rate for 2023 
and 2022.

Income (Loss) from Operating Affiliates.

We recorded $184 million of net income from our operating 
affiliates  in  the  2023  period,  compared  to  income  of  $75 
million  in  the  2022  period  and  primarily  reflects  amounts 
related  to  the  Company’s  investment  in  Somers  Group 
Holdings  Ltd.  and  Coface  SA.  See  note  9,  “Investment 
Information—Investments  in  Operating  Affiliates,”  to  our 
consolidated financial statements for additional information.

Net  realized  gains  or  losses  also  include  realized  and 
unrealized  contract  gains  and  losses  on  our  derivative 
instruments, changes in the fair value of assets accounted for 
using  the  fair  value  option  and  in  the  fair  value  of  equities, 
along  with  changes  in  the  allowance  for  credit  losses  on 
financial  assets  and  net  impairment  losses  recognized  in 
earnings. See note 9, “Investment Information—Net Realized 
Gains  (Losses),”  and  note  9,  “Investment  Information—
Allowance  for  Credit  Losses,”  to  our  consolidated  financial 
statements for additional information.

Equity  in  Net  Income  (Loss)  of  Investments  Accounted  for 
Using the Equity Method. 

the  equity  method 

We recorded $278 million of equity in net income related to 
investments accounted for using the equity method for 2023, 
compared  to  $115  million  for  2022.  Investments  accounted 
totaled  $4.6  billion  at 
for  using 
to  $3.8  billion  at 
December  31,  2023,  compared 
December  31,  2022.  See  note  9,  “Investment  Information—
Equity  in  Net  Income  (Loss)  of  Investments  Accounted  For 
Using  the  Equity  Method,”  to  our  consolidated  financial 
statements in Item 8 for additional information.

Other Income or Losses

Other income for the 2023 period was $27 million, compared 
to a loss of $27 million for the 2022 period. Amounts in both 
periods primarily reflect changes in the cash surrender value 
of our investment in corporate-owned life insurance.

Corporate Expenses. 

Corporate expenses were $96 million for 2023, compared to 
$95  million  for  2022.  Such  amounts  primarily  represent 
certain  holding  company  costs  necessary  to  support  our 
worldwide operations and costs associated with operating as 
a publicly traded company. 

Transaction Costs and Other.

Transaction  costs  and  other  were  $6  million  for  2023, 
compared to nil for 2022. The 2023 expenses were primarily 
related to acquisition activity.

Amortization of Intangible Assets.

Amortization  of  intangible  assets  for  2023  was  $95  million, 
compared  to  $106  million  for  2022.  Amounts  in  2023  and 
to  amortization  of  finite-lived 
2022  primarily  related 
intangible assets. See note 2, “Acquisitions."

SUMMARY OF CRITICAL ACCOUNTING 
ESTIMATES 

At  December  31,  2023  and  2022,  our  Loss  Reserves,  net  of 
unpaid  losses  and  loss  adjustment  expenses  recoverable,  by 
type and by operating segment were as follows:

recognition, 

The  preparation  of  consolidated  financial  statements  in 
accordance with GAAP requires us to make many estimates 
and  judgments  that  affect  the  reported  amounts  of  assets, 
liabilities  (including  reserves),  revenues  and  expenses,  and 
related  disclosures  of  contingent  liabilities.  On  an  ongoing 
basis,  we  evaluate  our  estimates,  including  those  related  to 
revenue 
reserves, 
insurance 
reinsurance  recoverables,  allowance  for  current  expected 
credit  losses,  investment  valuations,  goodwill  and  intangible 
assets, bad debts, income taxes, contingencies and litigation. 
We  base  our  estimates  on  historical  experience,  where 
possible, and on various other assumptions that we believe to 
be reasonable under the circumstances, which form the basis 
for  our  judgments  about  the  carrying  values  of  assets  and 
liabilities  that  are  not  readily  apparent  from  other  sources. 
Actual  results  will  differ  from  these  estimates  and  such 
differences  may  be  material.  We  believe  that  the  following 
critical  accounting  policies  affect  significant  estimates  used 
in the preparation of our consolidated financial statements.

loss 
adjustment expenses, or “Loss Reserves”, that arise from the 
business  we  underwrite.  Loss  Reserves  for  our  insurance, 
reinsurance  and  mortgage  operations  are  balance  sheet 
liabilities  representing  estimates  of  future  amounts  required 
to  pay  losses  and  loss  adjustment  expenses  for  insured  or 
reinsured events which have occurred at or before the balance 
sheet date. Loss Reserves do not reflect contingency reserve 
allowances  to  account  for  future  loss  occurrences.  Losses 
arising from future events will be estimated and recognized at 
the time the losses are incurred and could be substantial. See 
note  6,  “Short  Duration  Contracts,”  to  our  consolidated 
financial  statements  in  Item  8  for  additional  information  on 
our reserving process.

December 31, 2022, 36.1% of total net reserves represent policy years 
2013 and prior and the remainder from later policy years. 

Potential Variability in Loss Reserves

The  following  tables  summarize  the  effect  of  reasonably 
likely  scenarios  on  the  key  actuarial  assumptions  used  to 
estimate  our  Loss  Reserves,  net  of  unpaid  losses  and  loss 
adjustment  expenses  recoverable,  at  December  31,  2023  by 
underwriting segment and reserving lines. See note 6, “Short 
Duration Contracts,” to our consolidated financial statements 
in Item 8 for a description of the lines of business included in 
each reserving line.

The scenarios shown in the tables summarize the effect of (i) 
changes  to  the  expected  loss  ratio  selections  used  at 
December  31,  2023,  which  represent  loss  ratio  point 
increases  or  decreases  to  the  expected  loss  ratios  used,  and 
(ii)  changes  to  the  loss  development  patterns  used  in  our 
reserving  process  at  December  31,  2023,  which  represent 
claims  reporting  that  is  either  slower  or  faster  than  the 
reporting  patterns  used.  We  believe  that  the  illustrated 
sensitivities are indicative of the potential variability inherent 
in  the  estimation  process  of  those  parameters.  The  results 
show  the  impact  of  varying  each  key  actuarial  assumption 
using  the  chosen  sensitivity  on  our  IBNR  reserves,  on  a  net 
basis and across all accident years.

It is not necessarily appropriate to sum the total impact for a 
specific  factor  or  the  total  impact  for  a  specific  business 
category  as 
the  business  categories  are  not  perfectly 
correlated. In addition, the potential variability shown in the 
tables above are reasonably likely scenarios of changes in our 
key assumptions at December 31, 2023 and are not meant to 
be  a  “best  case”  or  “worst  case”  series  of  outcomes  and 
therefore, it is possible that future variations may be more or 
less than the amounts set forth above.

For  our  mortgage  segment,  we  considered  the  sensitivity  of 
loss reserve estimates at December 31, 2023 by assessing the 
potential  changes  resulting  from  a  parallel  shift  in  severity 
and  default  to  claim  rate.  For  example,  assuming  all  other 
factors  remain  constant,  for  every  one  percentage  point 
change  in  primary  claim  severity  (which  we  estimate  to  be 
approximately  29%  of  the  unpaid  principal  balance  at 
December  31,  2023),  we  estimated  that  our  loss  reserves 
would change by approximately $17 million at December 31, 
2023. For every one percentage point change in our primary 
net  default 
to  be 
approximately  27%  at  December  31,  2023),  we  estimated  a 
$18  million  change  in  our  loss  reserves  at  December  31, 
2023.

Reserves,  we  used  a  Monte  Carlo  simulation  approach  to 
simulate  a  range  of  results  based  on  various  probabilities. 
Both  the  probabilities  and  related  modeling  are  subject  to 
inherent  uncertainties.  The  simulation  relies  on  a  significant 
number  of  assumptions,  such  as  the  potential  for  multiple 
entities  to  react  similarly  to  external  events,  and  includes 
other  statistical  assumptions.  The  simulation  results  shown 
for each segment do not add to the total simulation results, as 
the  individual  segment  simulation  results  do  not  reflect  the 
diversification effects across our segments. 

At  December  31,  2023,  our  recorded  Loss  Reserves  by 
underwriting  segment,  net  of  unpaid 
loss 
adjustment  expenses  recoverable,  and  the  results  of  the 
simulation were as follows:

For  informational  purposes,  based  on  the  total  simulation 
results,  a  change  in  our  Loss  Reserves  to  the  amount 
indicated at the 90th percentile would result in a decrease in 
income before income taxes of approximately $2.8 billion, or 
$7.27 per diluted share, while a change in our Loss Reserves 
to the amount indicated at the 10th percentile would result in 
an increase in income before income taxes of approximately 
$2.6 billion, or $6.95 per diluted share. The simulation results 
noted above are informational only, and no assurance can be 
given  that  our  ultimate  losses  will  not  be  significantly 
different  than  the  simulation  results  shown  above,  and  such 
differences  could  directly  and  significantly  impact  earnings

assumptions  made  as  part  of  the  reserving  process  could 
prove  to  be  inaccurate  due  to  several  factors,  including  the 
fact  that  for  certain  lines  of  business  relatively  limited 
historical  information  has  been  reported  to  us  through 
December  31,  2023.  Accordingly,  the  reserving  for  incurred 
losses  in  these  lines  of  business  could  be  subject  to  greater

agreements.  Our 

In the normal course of business, our insurance and mortgage 
insurance  operations  cede  a  portion  of  their  premium  on  a 
quota  share  or  excess  of  loss  basis  through  treaty  or 
facultative 
reinsurance 
operations also obtain reinsurance whereby another reinsurer 
contractually agrees to indemnify it for all or a portion of the 
reinsurance risks underwritten by our reinsurance operations. 
Such arrangements, where one reinsurer provides reinsurance 
to another reinsurer, are usually referred to as “retrocessional 
reinsurance”  arrangements.  In  addition,  our  reinsurance 
subsidiaries  participate  in  “common  account”  retrocessional 
arrangements for certain pro rata treaties. Such arrangements 
reduce  the  effect  of  individual  or  aggregate  losses  to  all 
companies  participating  on  such  treaties,  including  the 
reinsurers, such as our reinsurance operations, and the ceding 
company.  Estimating  reinsurance  recoverables  can  be  more 
subjective than estimating the underlying reserves for losses 
and loss adjustment expenses as discussed above in “—Loss 
Reserves.”  In  particular,  reinsurance  recoverables  may  be 
affected  by  deemed  inuring  reinsurance,  industry  losses

reported  by  various  statistical  reporting  services,  and  other 
factors.  Reinsurance  recoverables  are  recorded  as  assets, 
predicated on the reinsurers’ ability to meet their obligations 
under the reinsurance agreements. If the reinsurers are unable 
to  satisfy  their  obligations  under  the  agreements,  our 
insurance or reinsurance operations would be liable for such 
defaulted amounts.

The  availability  and  cost  of  reinsurance  and  retrocessional 
protection is subject to market conditions, which are beyond 
our  control.  Although  we  believe  that  our  insurance  and 
reinsurance  operations  have  been  successful  in  obtaining 
adequate  reinsurance  and  retrocessional  protection,  it  is  not 
certain  that  they  will  be  able  to  continue  to  obtain  adequate 
protection at cost effective levels. As a result of such market 
conditions  and  other  factors,  our  insurance,  reinsurance  and 
mortgage operations may not be able to successfully mitigate 
risk through reinsurance and retrocessional arrangements and 
may lead to increased volatility in our results of operations in 
future  periods.  See  Item  1A,  “Risk  Factors—Risks  Relating 
to Our Industry, Business and Operations—The failure of any 
of  the  loss  limitation  methods  we  employ  could  have  a 
material adverse effect on our financial condition or results of 
operations.”

For purposes of managing risk, we reinsure a portion of our 
exposures,  paying  to  reinsurers  a  part  of  the  premiums 
received  on  the  policies  we  write,  and  we  may  also  use 
retrocessional  protection.  On  a  consolidated  basis,  ceded 
premiums  written  represented  26.8%  of  gross  premiums 
written  for  2023,  compared  to  27.7%  for  2022.  We  monitor 
the financial condition of our reinsurers and attempt to place 
coverages only with substantial, financially sound carriers. If 
the  financial  condition  of  our  reinsurers  or  retrocessionaires 
deteriorates,  resulting  in  an  impairment  of  their  ability  to 
make  payments,  we  will  be  responsible  for  probable  losses 
resulting from our inability to collect amounts due from such 
parties,  as  appropriate.  We  evaluate  the  credit  worthiness  of 
all  the  reinsurers  to  which  we  cede  business.  We  report 
reinsurance  recoverables  net  of  an  allowance  for  expected 
credit loss. The allowance is based upon our ongoing review 
of  amounts  outstanding,  the  financial  condition  of  our 
reinsurers, amounts and form of collateral obtained and other 
relevant  factors.  A  ratings  based  probability-of-default  and 
loss-given-default  methodology  is  used  to  estimate  the 
allowance  for  expected  credit  loss.  See  Item  1A,  “Risk 
Factors—Risks  Relating  to  Our  Industry,  Business  and 
Operations—We  are  exposed  to  credit  risk  in  certain  of  our 
business operations” and “Financial Condition, Liquidity and 
Capital Resources” for further details.

We  have  entered  into  various  aggregate  excess  of  loss 
reinsurance  agreements  with  various  special  purpose 
reinsurance  companies  domiciled  in  Bermuda.  These  are 
special  purpose  variable 
that  are  not 
consolidated in our financial results because we do not have 

interest  entities 

the  unilateral  power  to  direct  those  activities  that  are 
significant  to  its  economic  performance.  See  note  12, 
“Variable  Interest  Entity  and  Noncontrolling  Interests,”  to 
our consolidated financial statements in Item 8 for additional 
information.

Premium Revenues and Related Expenses

Insurance  premiums  written  are  generally  recorded  at  the 
policy inception and are primarily earned on a pro rata basis 
over  the  terms  of  the  policies  for  all  products,  usually  12 
months. Premiums written include estimates in our insurance 
operations’  programs,  specialty  lines,  collateral  protection 
business  and  for  participation  in  involuntary  pools.  Such 
premium  estimates  are  derived  from  multiple  sources  which 
include  the  historical  experience  of  the  underlying  business, 
similar  business  and  available 
information. 
Unearned  premium  reserves  represent 
the  portion  of 
premiums  written  that  relates  to  the  unexpired  terms  of  in-
force insurance policies.

industry 

Reinsurance  premiums  written  include  amounts  reported  by 
brokers  and  ceding  companies,  supplemented  by  our  own 
estimates of premiums where reports have not been received. 
The determination of premium estimates requires a review of 
our  experience  with  the  ceding  companies,  familiarity  with 
each  market,  the  timing  of  the  reported  information,  an 
analysis and understanding of the characteristics of each line 
of  business,  and  management’s  judgment  of  the  impact  of 
various  factors,  including  premium  or  loss  trends,  on  the 
volume  of  business  written  and  ceded  to  us.  On  an  ongoing 
basis, our underwriters review the amounts reported by these 
third parties for reasonableness based on their experience and 
knowledge  of  the  subject  class  of  business,  taking  into 
account our historical experience with the brokers or ceding 
companies. In addition, reinsurance contracts under which we 
assume business generally contain specific provisions which 
allow us to perform audits of the ceding company to ensure 
compliance  with  the  terms  and  conditions  of  the  contract, 
including accurate and timely reporting of information. Based 
on  a  review  of  all  available  information,  management 
establishes  premium  estimates  where  reports  have  not  been 
received.  Premium  estimates  are  updated  when  new 
is  received  and  differences  between  such 
information 
estimates  and  actual  amounts  are  recorded  in  the  period  in 
which  estimates  are  changed  or  the  actual  amounts  are 
determined. Premiums written are recorded based on the type 
of  contracts  we  write.  Premiums  on  our  excess  of  loss  and 
pro  rata  reinsurance  contracts  are  estimated  when  the 
business  is  underwritten.  For  excess  of  loss  contracts, 
premiums  are  recorded  as  written  based  on  the  terms  of  the 
contract.  Estimates  of  premiums  written  under  pro  rata 
contracts are recorded in the period in which the underlying 
risks  incept  and  are  based  on  information  provided  by  the 
brokers and the ceding companies. For multi-year reinsurance 
treaties  which  are  payable  in  annual  installments,  generally,

a  review  of  the  aging  and  collection  of  premium  estimates. 
Based  on  management’s  review,  the  appropriateness  of  the 
premium estimates is evaluated, and any adjustment to these 
estimates  is  recorded  in  the  period  in  which  it  becomes 
known. Adjustments to premium estimates could be material 
and such adjustments could directly and significantly impact 
earnings  favorably  or  unfavorably  in  the  period  they  are 
determined  because  the  estimated  premium  may  be  fully  or 
substantially earned.

A  significant  portion  of  amounts  included  as  premiums 
receivable,  which  represent  estimated  premiums  written,  net 
of commissions, are not currently due based on the terms of 
the  underlying  contracts.  Based  on  currently  available 
information,  we  report  premiums  receivable  net  of  an 
allowance  for  expected  credit  loss.  We  monitor  credit  risk 
associated  with  premiums  receivable  through  our  ongoing 
review  of  amounts  outstanding,  aging  of  the  receivable, 
historical data and counterparty financial strength measures.

Reinsurance  premiums  assumed,  irrespective  of  the  class  of 
business,  are  generally  earned  on  a  pro  rata  basis  over  the 
terms  of  the  underlying  policies  or  reinsurance  contracts. 
Contracts  and  policies  written  on  a  “losses  occurring”  basis 
cover  claims  that  may  occur  during  the  term  of  the  contract 
or  policy,  which  is  typically  12  months.  Accordingly,  the 
premium is earned evenly over the term. Contracts which are 
written on a “risks attaching” basis cover claims which attach 
to the underlying insurance policies written during the terms 
of such contracts. Premiums earned on such contracts usually 
extend  beyond  the  original  term  of  the  reinsurance  contract, 
typically resulting in recognition of premiums earned over a 
24-month period.

Certain  of  our  reinsurance  contracts  include  provisions  that 
adjust  premiums  or  acquisition  expenses  based  upon  the 
experience under the contracts. Premiums written and earned, 
as  well  as  related  acquisition  expenses,  are  recorded  based 
upon the projected experience under such contracts.

Retroactive  reinsurance  reimburses  a  ceding  company  for 
liabilities incurred as a result of past insurable events covered 
by  the  underlying  policies  reinsured.  In  certain  instances, 
reinsurance contracts cover losses both on a prospective basis 
and on a retroactive basis and, accordingly, we bifurcate the 
prospective  and  retrospective  elements  of  these  reinsurance 
contracts  and  accounts  for  each  element  separately  where 
practical. Underwriting income generated in connection with 
retroactive  reinsurance  contracts  is  deferred  and  amortized 
into  income  over  the  settlement  period  while  losses  are 
charged  to  income  immediately.  Subsequent  changes  in 
estimated  amount  or  timing  of  cash  flows  under  such 
retroactive  reinsurance  contracts  are  accounted  for  by 
adjusting the previously deferred amount to the balance that 
would have existed had the revised estimate been available at 
transaction,  with  a 
the 
corresponding charge or credit to income.

the  reinsurance 

inception  of 

Mortgage  guaranty  insurance  policies  are  contracts  that  are 
generally  non-cancelable  by  the  insurer,  are  renewable  at  a 
fixed  price,  and  provide  for  payment  of  premiums  on  a 
monthly,  annual  or  single  basis.  Upon  renewal,  we  are  not 
able to re-underwrite or re-price our policies. Consistent with 
industry  accounting  practices,  premiums  written  on  a 
monthly basis are earned as coverage is provided. Premiums 
written  on  an  annual  basis  are  amortized  on  a  monthly  pro 
rata  basis  over  the  year  of  coverage.  Primary  mortgage 
insurance  premiums  written  on  policies  covering  more  than 
one year are referred to as single premiums. A portion of the 
revenue  from  single  premiums  is  recognized  in  premiums 
earned  in  the  current  period,  and  the  remaining  portion  is 
deferred as unearned premiums and earned over the estimated 
expiration  of  risk  of  the  policy.  If  single  premium  policies 
related  to  insured  loans  are  canceled  for  any  reason  and  the 
policy  is  a  non-refundable  product,  the  remaining  unearned

premium  related  to  each  canceled  policy  is  recognized  as 
earned premium upon notification of the cancellation. 

Unearned  premiums  represent  the  portion  of  premiums 
written  that  is  applicable  to  the  estimated  unexpired  risk  of 
insured  loans.  A  portion  of  premium  payments  may  be 
refundable  if  the  insured  cancels  coverage,  which  generally 
occurs  when  the  loan  is  repaid,  the  loan  amortizes  to  a 
sufficiently  low  amount  to  trigger  a  lender  permitted  or 
legally required cancellation, or the value of the property has 
increased  sufficiently  in  accordance  with  the  terms  of  the 
contract.  Premium  refunds  reduce  premiums  earned  in  the 
consolidated statements of income. Generally, only unearned 
premiums are refundable.

Acquisition costs that are directly related and incremental to 
the successful acquisition or renewal of business are deferred 
and amortized based on the type of contract. For property and 
insurance  and  reinsurance  contracts,  deferred 
casualty 
acquisition  costs  are  amortized  over  the  period  in  which  the 
related  premiums  are  earned.  Consistent  with  mortgage 
insurance  industry  accounting  practice,  amortization  of 
acquisition costs related to the mortgage insurance contracts 
for each underwriting year’s book of business is recorded in 
proportion to estimated gross profits. Estimated gross profits 
are  comprised  of  earned  premiums  and  losses  and  loss 
adjustment  expenses.  For  each  underwriting  year,  we 
estimate the rate of amortization to reflect actual experience 
and any changes to persistency or loss development.

Acquisition  expenses  and  other  expenses  related  to  our 
underwriting  operations  that  vary  with,  and  are  directly 
related  to,  the  successful  acquisition  or  renewal  of  business 
are deferred and amortized based on the type of contract. Our 
insurance  and  reinsurance  operations  capitalize  incremental 
direct external costs that result from acquiring a contract but 
do  not  capitalize  salaries,  benefits  and  other 
internal 
underwriting  costs.  For  our  mortgage  insurance  operations, 
which  include  a  substantial  direct  sales  force,  both  external 
and  certain  internal  direct  costs  are  deferred  and  amortized. 
Deferred  acquisition  costs  are  carried  at  their  estimated 
realizable value and take into account anticipated losses and 
loss  adjustment  expenses,  based  on  historical  and  current 
experience, and anticipated investment income. 

A premium deficiency occurs if the sum of anticipated losses 
and  loss  adjustment  expenses,  unamortized  acquisition  costs 
and  maintenance  costs  and  anticipated  investment  income 
exceed  unearned  premiums.  A  premium  deficiency  reserve 
(“PDR”) is recorded by charging any unamortized acquisition 
costs  to  expense  to  the  extent  required  in  order  to  eliminate 
the  deficiency. 
the  premium  deficiency  exceeds 
unamortized  acquisition  costs  then  a  liability  is  accrued  for 
the excess deficiency.

income.  Evaluating 

To assess the need for a PDR on our mortgage exposures, we 
develop  loss  projections  based  on  modeled  loan  defaults 
related  to  our  current  policies  in  force.  This  projection  is 
based  on  recent  trends  in  default  experience,  severity  and 
rates  of  defaulted  loans  moving  to  claim,  as  well  as  recent 
trends in the rate at which loans are prepaid, and incorporates 
anticipated 
the  expected 
profitability of our existing mortgage insurance business and 
the  need  for  a  PDR  for  our  mortgage  business  involves 
significant  reliance  upon  assumptions  and  estimates  with 
regard  to  the  likelihood,  magnitude  and  timing  of  potential 
losses and premium revenues. The models, assumptions and 
estimates we use to evaluate the need for a PDR may prove to 
be  inaccurate,  especially  during  an  extended  economic 
downturn  or  a  period  of  extreme  market  volatility  and 
uncertainty.

No premium deficiency charges were recorded by us during 
2023 or 2022.

Net Deferred Income Tax Assets Measurement

On December 27, 2023 the Bermuda government enacted tax 
legislation referred to as the Corporate Income Tax Act 2023 
(“Bermuda  CIT  Act”).  The  Bermuda  CIT  Act  establishes  a 
15% corporate income tax, for in-scope businesses, for fiscal 
years  beginning  on  or  after  January  1,  2025.  The  enacted 
legislation  includes  a  provision  referred  to  as  the  Economic 
Transition  Adjustment,  which  requires  Bermuda  Constituent 
entities  to  establish  tax  basis  in  their  assets  and  liabilities, 
excluding goodwill, based on fair value as of September 30, 
2023.  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.

Using  fair  value  to  establish  tax  basis  in  the  assets  and 
liabilities  of  our  Bermuda  entities  results  in  deductible  and 
taxable temporary differences which are reflected as deferred 
income tax assets and liabilities, respectively, in our financial 
statements.  The  enactment  of  Bermuda  CIT  Act  resulted  in 
the  establishment  of  a  $1.18  billion  net  deferred  income  tax 
asset.  Such  amount  is  included  in  “Other  assets”  on  the 
Company’s balance sheet. 

The  most  significant  deferred  income  tax  assets  recognized 
relate to the fair value adjustments for identifiable intangible 
assets.  We  estimated  the  fair  value  of  the  identifiable 
intangible  assets  of  our  Bermuda  entities  using  discounted 
cash  flow  (“DCF”)  models.  The  significant  assumptions 
utilized  in  the  DCF  models  included  the  future  revenue  and 
profits expected to be generated by the identifiable intangible 
assets and the discount rates. See note 15, “Income Taxes” to 
our  consolidated  financial  statements 
in  Item  8  for 
disclosures  concerning  our  Company’s  deferred  income  tax 
asset.

FINANCIAL CONDITION

Investable Assets

At  December  31,  2023,  total  investable  assets  held  by  Arch 
were $34.6 billion.

Investable Assets Held by Arch 

The  Finance,  Investment  and  Risk  Committee  (“FIR 
Committee”)  of  our  Board  of  Directors  (the  “Board”) 
establishes  our  investment  policies  and  sets  the  parameters 
for creating guidelines for our investment managers. The FIR 
reviews  the  implementation  of  the  investment  strategy  on  a 
regular  basis.  Our  current  approach  stresses  preservation  of 
capital,  market  liquidity  and  diversification  of  risk.  While 
maintaining  our  emphasis  on  preservation  of  capital  and 
liquidity, we expect our portfolio to become more diversified 
and,  as  a  result,  we  may  expand  into  areas  which  are  not 
investment  strategy.  Our  Chief 
currently  part  of  our 
Investment  Officer  administers  the  investment  portfolio, 
oversees our investment managers and formulates investment 
strategy 
the  FIR  Committee.  At 
December 31, 2023, approximately $21.9 billion, or 63%, of 

in  conjunction  with 

total investable assets held by Arch were internally managed, 
compared to $18.8 billion, or 67%, at December 31, 2022.

Reserves for Losses and Loss Adjustment Expenses

We  establish  Loss  Reserves  which  represent  estimates 
involving actuarial and statistical projections, at a given point 
in  time,  of  our  expectations  of  the  ultimate  settlement  and 
administration  costs  of  losses  incurred.  Estimating  Loss 
Reserves  is  inherently  difficult.  We  utilize  actuarial  models 
as  well  as  available  historical  insurance  industry  loss  ratio 
experience  and  loss  development  patterns  to  assist  in  the 
establishment  of  Loss  Reserves.  Actual  losses  and  loss 
adjustment expenses paid will deviate, perhaps substantially, 
from 
in  our  financial 
statements.  See  “Management’s  Discussion  and  Analysis  of 
Financial Condition and Results of Operations—Summary of 
Critical Accounting Estimates—Loss Reserves” and see Item 
1, “Business—Reserves” for further details.

LIQUIDITY

Liquidity is a measure of our ability to access sufficient cash 
flows to meet the short-term and long-term cash requirements 
of our business operations. 

Arch  Capital  is  a  holding  company  whose  assets  primarily 
consist  of  the  shares  in  its  subsidiaries.  Generally,  Arch 
Capital  depends  on  its  available  cash  resources,  liquid 
investments  and  dividends  or  other  distributions  from  its 
subsidiaries to make payments, including the payment of debt 
service  obligations  and  operating  expenses  it  may  incur  and 
any  dividends  or  liquidation  amounts  with  respect  to  our 
preferred and common shares. 

In  2023,  Arch  Capital  received  dividends  of  $164  million 
from  Arch  Reinsurance  Ltd.  (“Arch  Re  Bermuda”),  our 
Bermuda-based reinsurer and insurer. Arch Re Bermuda can 
pay  approximately  $4.8  billion  to  Arch  Capital  in  2024 
without  providing  an  affidavit  to  the  Bermuda  Monetary 
Authority (“BMA”). 

received 

Our insurance and reinsurance operations provide liquidity in 
that  premiums  are 
in  advance,  sometimes 
substantially  in  advance,  of  the  time  losses  are  paid.  The

operations,  financing  arrangements  or  routine  sales  of 
investments.

As  part  of  our  investment  strategy,  we  seek  to  establish  a 
level  of  cash  and  highly  liquid  short-term  and  intermediate-
term securities which, combined with expected cash flow, is 
believed  by  us  to  be  adequate  to  meet  our  foreseeable 
payment  obligations.  However,  due  to  the  nature  of  our 
operations,  cash  flows  are  affected  by  claim  payments  that 
may comprise large payments on a limited number of claims 
and  which  can  fluctuate  from  year  to  year.  We  believe  that 
our  liquid  investments  and  cash  flow  will  provide  us  with 
sufficient  liquidity  in  order  to  meet  our  claim  payment 
obligations. However, the timing and amounts of actual claim 
payments  related  to  recorded  Loss  Reserves  vary  based  on 
many  factors,  including  large  individual  losses,  changes  in 
the legal environment, as well as general market conditions. 
The  ultimate  amount  of  the  claim  payments  could  differ 
materially  from  our  estimated  amounts.  Certain  lines  of 
business  written  by  us,  such  as  excess  casualty,  have  loss 
experience characterized as low frequency and high severity. 
The  foregoing  may  result  in  significant  variability  in  loss 
payment  patterns.  The  impact  of  this  variability  can  be 
exacerbated  by  the  fact  that  the  timing  of  the  receipt  of 
reinsurance  recoverables  owed  to  us  may  be  slower  than 
anticipated  by  us.  Therefore,  the  irregular  timing  of  claim 
payments can create significant variations in cash flows from 
operations  between  periods  and  may  require  us  to  utilize 
other  sources  of  liquidity  to  make  these  payments,  which 
may include the sale of investments or utilization of existing 
or  new  credit  facilities  or  capital  market  transactions.  If  the 
source  of  liquidity  is  the  sale  of  investments,  we  may  be 
forced  to  sell  such  investments  at  a  loss,  which  may  be 
material.

We expect that our liquidity needs, including our anticipated 
insurance  obligations  and  operating  and  capital  expenditure 
needs,  will  be  met  by  funds  generated  from  underwriting 
activities and investment income, as well as by our balance of 
cash, short-term investments, proceeds on the sale or maturity 
of  our  investments,  and  our  credit  facilities,  for  the  next 
twelve months, at a minimum.

Dividend Restrictions 

Arch  Capital  has  no  material  restrictions  on  its  ability  to 
make  distributions  to  shareholders.  However,  the  ability  of 
our  regulated  insurance  and  reinsurance  subsidiaries  to  pay 
dividends  or  make  distributions  or  other  payments  to  us  is 
limited by the applicable local laws and relevant regulations 
of the various countries and states in which we operate. See 
note  25,  “Statutory  Information,” 
to  our  consolidated 
financial  statements  in  Item  8  for  additional  information  on 
dividend restrictions.

The payment of dividends from Arch Re Bermuda is, under 
certain  circumstances,  limited  under  Bermuda  law,  which 
requires  our  Bermuda  operating  subsidiary  to  maintain 
certain measures of solvency and liquidity.

Our  U.S.  insurance  and  reinsurance  subsidiaries  are  subject 
to insurance laws and regulations in the jurisdictions in which 
they  operate.  The  ability  of  our  regulated 
insurance 
subsidiaries  to  pay  dividends  or  make  distributions  is 
dependent  on  their  ability  to  meet  applicable  regulatory 
standards. These regulations include restrictions that limit the 
amount  of  dividends  or  other  distributions,  such  as  loans  or 
cash  advances,  available  to  shareholders  without  prior 
approval  of  the  insurance  regulatory  authorities.  Each  state 
requires  prior  regulatory  approval  of  any  payment  of 
extraordinary dividends.

We  also  have  insurance  subsidiaries  that  are  the  parent 
company  for  other  insurance  subsidiaries,  which  means  that 
dividends  and  other  distributions  will  be  subject  to  multiple 
layers of regulations in order for our insurance subsidiaries to 
be able to dividend funds to Arch Capital. The inability of the 
subsidiaries  of  Arch  Capital  to  pay  dividends  and  other 
permitted  distributions  could  have  a  material  adverse  effect 
on Arch Capital’s cash requirements and our ability to make 
principal, interest and dividend payments on the senior notes, 
preferred shares and common shares.

In  addition  to  meeting  applicable  regulatory  standards,  the 
ability  of  our  insurance  and  reinsurance  subsidiaries  to  pay 
dividends  is  also  constrained  by  our  dependence  on  the 
financial  strength  ratings  of  our  insurance  and  reinsurance 
subsidiaries  from  independent  rating  agencies.  The  ratings 
from  these  agencies  depend  to  a  large  extent  on  the 
capitalization 
insurance  and  reinsurance 
subsidiaries. We believe that Arch Capital has sufficient cash 
resources  and  available  dividend  capacity  to  service  its 
indebtedness and other current outstanding obligations.

third  parties.  Our  insurance  and  reinsurance  subsidiaries 
maintain  assets  in  trust  accounts  as  collateral  for  insurance 
and  reinsurance  transactions  with  affiliated  companies  and 
also  have  investments  in  segregated  portfolios  primarily  to 
provide  collateral  or  guarantees  for  letters  of  credit  to  third 
parties.  At  December  31,  2023  and  2022,  such  amounts 
approximated $9.9 billion and $8.7 billion, respectively.

investments  and  investments  in  operating  affiliates  may  be 
illiquid  due  to  contractual  provisions  or  investment  market 
conditions. If we require significant amounts of cash on short 
notice  in  excess  of  anticipated  cash  requirements,  then  we 
may  have  difficulty  selling  these  investments  in  a  timely 
manner  or  may  be  forced  to  sell  or  terminate  them  at 
unfavorable  values.  Our  unfunded  investment  commitments 
totaled approximately $3.6 billion at December 31, 2023 and 
are  callable  by  our  investment  managers.  The  timing  of  the 
funding  of  investment  commitments  is  uncertain  and  may 
require us to access cash on short notice.

Investments 

At  December  31,  2023,  our  investable  assets  were  $34.6 
billion. The primary goals of our asset liability management 
process  are  to  meet  our  insurance  liabilities,  manage  the 
interest  rate  risk  embedded  in  those  insurance  liabilities  and 
maintain sufficient liquidity to cover fluctuations in projected 
liability  cash  flows,  including  debt  service  obligations. 
Generally,  the  expected  principal  and  interest  payments 
produced  by  our  fixed  income  portfolio  adequately  fund  the 
estimated  runoff  of  our  insurance  reserves.  Although  this  is 
not an exact cash flow match in each period, the substantial 
degree by which the fair value of the fixed income portfolio 
exceeds  the  expected  present  value  of  the  net  insurance 
liabilities, as well as the positive cash flow from newly sold 
policies  and  the  large  amount  of  high  quality  liquid  bonds, 
provide  assurance  of  our  ability  to  fund  the  payment  of 
claims and to service our outstanding debt without having to 
sell  securities  at  distressed  prices  or  access  credit  facilities.

Cash provided by operating activities for the 2023 period was 
higher than in the 2022 period. Activity for the 2023 period 
primarily reflected a higher level of premiums collected than

Cash  used  for  investing  activities  for  the  2023  period 
reflected  higher  net  purchases  than  in  the  2022  period, 
primarily reflecting the strong operating cash flows in 2023.

Cash  used  for  financing  activities  for  the  2023  period  was 
lower  than  in  the  2022  period.  Activity  for  the  2022  period 
included $586 million of share repurchases.

Capital Adequacy

We monitor our capital adequacy on a regular basis and will 
seek to adjust our capital base (up or down) according to the 
needs of our business. The future capital requirements of our 
business will depend on many factors, including our ability to 
write  new  business  successfully  and  to  establish  premium 
rates  and  reserves  at  levels  sufficient  to  cover  losses.  Our 
ability to underwrite is largely dependent upon the quality of 
our claims paying and financial strength ratings as evaluated 
by independent rating agencies. In particular, we require (1) 
sufficient capital to maintain our financial strength ratings, as 
issued  by  several  ratings  agencies,  at  a  level  considered 
necessary  by  management  to  enable  our  key  operating 
subsidiaries  to  compete;  (2)  sufficient  capital  to  enable  our 
underwriting  subsidiaries  to  meet  the  capital  adequacy  tests 
performed  by  statutory  agencies  in  the  U.S.  and  other  key 
markets;  and  (3)  our  non-U.S.  operating  companies  are 
required to post letters of credit and other forms of collateral 
that  are  necessary  for  them  to  operate  as  they  are  “non-
admitted” under U.S. state insurance regulations.

required 

to  maintain  compliance  with 

In  addition,  AMIC  and  UGRIC  (together,  “Arch  MI  U.S.”) 
are 
the  GSE 
requirements, known as PMIERs. The financial requirements 
require an eligible mortgage insurer’s available assets, which 
generally include only the most liquid assets of an insurer, to 
meet or exceed “minimum required assets” as of each quarter 
end.  Minimum  required  assets  are  calculated  from  PMIERs 
tables  with  several  risk  dimensions  (including  origination 
year,  original  loan-to-value  and  original  credit  score  of 
performing  loans,  and  the  delinquency  status  of  non-
performing  loans)  and  are  subject  to  a  minimum  amount. 
Arch  MI  U.S.  satisfied  the  PMIERs’  financial  requirements 
as of December 31, 2023 with a PMIER sufficiency ratio of 
213%, compared to 236% at December 31, 2022.

As part of our capital management program, we may seek to 
raise  additional  capital  or  may  seek  to  return  capital  to  our 
shareholders  through  share  repurchases,  cash  dividends  or 
other methods (or a combination of such methods). Any such 
determination will be at the discretion of the Board and will 
be  dependent  upon  our  profits,  financial  requirements  and 
other  factors,  including  legal  restrictions,  rating  agency 
requirements  and  such  other  factors  as  our  Board  deems 
relevant.

To the extent that our existing capital is insufficient to fund 
our  future  operating  requirements  or  maintain  such  ratings, 
we may need to raise additional funds through financings or 
limit  our  growth.  We  can  provide  no  assurance  that,  if 
needed, we would be able to obtain additional funds through 
financing  on  satisfactory  terms  or  at  all.  Any  adverse 
developments  in  the  financial  markets,  such  as  disruptions, 
uncertainty or volatility in the capital and credit markets, may 
result in realized and unrealized capital losses that could have 

a  material  adverse  effect  on  our  results  of  operations, 
financial position and our businesses, and may also limit our 
access to capital required to operate our business. In addition 
to  common  share  capital,  we  depend  on  external  sources  of 
finance  to  support  our  underwriting  activities,  which  can  be 
in  the  form  (or  any  combination)  of  debt  securities, 
preference  shares,  common  equity  and  bank  credit  facilities 
providing loans and/or letters of credit. 

Arch  Capital,  through  its  subsidiaries,  provides  financial 
support to certain of its insurance subsidiaries and affiliates, 
through  certain  reinsurance  arrangements  beneficial  to  the 
ratings  of  such  subsidiaries.  Historically,  our  insurance, 
reinsurance and mortgage insurance subsidiaries have entered 
into  separate  reinsurance  arrangements  with  Arch  Re 
Bermuda covering individual lines of business.

Except as described in the above paragraph, or where express 
reinsurance,  guarantee  or  other  financial  support  contractual 
arrangements are in place, each of Arch Capital’s subsidiaries 
or  affiliates  is  solely  responsible  for  its  own  liabilities  and 
commitments  (and  no  other  Arch  Capital  subsidiary  or 
affiliate  is  so  responsible).  Any  reinsurance  arrangements, 
guarantees 
contractual 
arrangements that are in place are solely for the benefit of the 
Arch Capital subsidiary or affiliate involved and third parties 
(creditors  or  insureds  of  such  entity)  are  not  express 
beneficiaries of such arrangements.

Share Repurchase Program 

Our  Board  has  authorized  the  investment  in  Arch  Capital’s 
common  shares  through  a  share  repurchase  program.  Since 
the  inception  of  the  share  repurchase  program  through 
December  31,  2023,  Arch  Capital  has 
repurchased 
approximately 433.6 million common shares for an aggregate 
purchase  price  of  $5.9  billion.  At  December  31,  2023,  $1.0 
billion  of  share  repurchases  were  available  under  the 
program.  Repurchases  under  the  program  may  be  effected 
from  time  to  time  in  open  market  or  privately  negotiated 
transactions  through  December  31,  2024.  The  timing  and 
amount  of  the  repurchase  transactions  under  this  program 
will  depend  on  a  variety  of  factors,  including  market 
conditions,  the  development  of  the  economy,  corporate  and 
regulatory  considerations.  We  will  continue  to  monitor  our 
share price and, depending upon results of operations, market 
conditions  and  the  development  of  the  economy,  as  well  as 
other  factors,  we  will  consider  share  repurchases  on  an 
opportunistic basis.

(1) The estimated expected contractual commitments related to the reserves for losses and loss adjustment expenses are presented on a gross basis (i.e., not
reflecting any corresponding reinsurance recoverable amounts that would be due to us). It should be noted that until a claim has been presented to us,
determined to be valid, quantified and settled, there is no known obligation on an individual transaction basis, and while estimable in the aggregate, the 
timing and amount contain significant uncertainty.

(2) Certain insurance policies written by our insurance operations feature large deductibles, primarily in construction and national accounts lines. Under such
contracts, we are obligated to pay the claimant for the full amount of the claim and are subsequently reimbursed by the policyholder for the deductible
amount. In the event we are unable to collect from the policyholder, we would be liable for such defaulted amounts.

(3) Unfunded investment commitments are callable by our investment managers. We have assumed that such investments will be funded in the next year but 

the funding may occur over a longer period of time, due to market conditions and other factors.

The  commitments  under  the  Credit  Facility  will  expire  on 
August  23,  2028,  and  all  loans  then  outstanding  under  the 
Credit Facility must be repaid at such time. Letters of credit 
issued  under  the  Credit  Facility  will  not  have  an  expiration

Letter of Credit and Revolving Credit Facilities

In  the  normal  course  of  its  operations,  the  Company  enters 
into  agreements  with  financial  institutions  to  obtain  secured 
and  unsecured  credit  facilities.  On  August  23,  2023,  Arch 
Capital  and  certain  of  its  subsidiaries  amended  the  existing 
credit agreement (the “Credit Facility”). The Credit Facility, 
as  amended,  consists  of  a  $425  million  secured  facility  for 
letters  of  credit  (the  “Secured  Facility”)  and  a  $500  million 
unsecured  facility  for  revolving  loans  and  letters  of  credit 
(the  “Unsecured  Facility”).  At  December  31,  2023,  the 
Secured  Facility  had  $273  million  of  letters  of  credit 
outstanding and remaining capacity of $152 million, and the 
Unsecured  Facility  had  no  outstanding  revolving  loans  or 
letters of credit, with remaining capacity of $500 million.

The  Credit  Facility  contains  certain  restrictive  covenants 
customary for facilities of this type, including restrictions on 
indebtedness,  consolidated  tangible  net  worth,  minimum 
shareholders’  equity  levels  and  minimum  financial  strength 
ratings.  Arch  Capital  and  its  subsidiaries  which  are  party  to 
the  agreement  were  in  compliance  with  all  covenants 
contained therein at December 31, 2023.

internationally 

Our  ability  to  underwrite  business  is  affected  by  the  quality 
of our claims paying ability and financial strength ratings as 
evaluated  by  independent  agencies.  Such  ratings  from  third 
rating 
party 
organizations or agencies are instrumental in establishing the 
financial  security  of  companies  in  our  industry.  We  believe 
that the primary users of such ratings include commercial and 
investment  banks,  policyholders,  brokers,  ceding  companies 
and  investors.  Insurance  ratings  are  also  used  by  insurance 
and  reinsurance  intermediaries  as  an  important  means  of 
assessing  the  financial  strength  and  quality  of  insurers  and 
reinsurers,  and  are  often  an  important  factor  in  the  decision 
by  an  insured  or  intermediary  of  whether  to  place  business 
with  a  particular 
reinsurance  provider. 
Periodically,  rating  agencies  evaluate  us  to  confirm  that  we 
continue  to  meet  their  criteria  for  the  ratings  assigned  to  us 
by  them.  S&P,  Moody’s,  A.M.  Best  Company  and  Fitch 
Ratings  are  ratings  agencies  which  have  assigned  financial 
strength ratings to one or more of Arch Capital’s subsidiaries.

If  we  are  not  able  to  obtain  adequate  capital,  our  business, 
results  of  operations  and  financial  condition  could  be 
adversely affected, which could include, among other things, 
the following possible outcomes: (1) potential downgrades in 
the financial strength ratings assigned by ratings agencies to 
our operating subsidiaries, which could place those operating 
subsidiaries  at  a  competitive  disadvantage  compared  to 
higher-rated  competitors;  (2)  reductions  in  the  amount  of 
business  that  our  operating  subsidiaries  are  able  to  write  in 
order  to  meet  capital  adequacy-based  tests  enforced  by 
statutory  agencies;  and  (3)  any  resultant  ratings  downgrades 
could, among other things, affect our ability to write business 
and  increase  the  cost  of  bank  credit  and  letters  of  credit.  In 
addition,  under  certain  of 
the  reinsurance  agreements 
assumed by our reinsurance operations, upon the occurrence 
of  a  ratings  downgrade  or  other  specified  triggering  event 
with  respect  to  our  reinsurance  operations,  such  as  a 
reduction  in  surplus  by  specified  amounts  during  specified 
periods,  our  ceding  company  clients  may  be  provided  with 
certain  rights,  including,  among  other  things,  the  right  to 
terminate the subject reinsurance agreement and/or to require 
that our reinsurance operations post additional collateral.

The  ratings  issued  on  our  companies  by  these  agencies  are 
announced  publicly  and  are  available  directly  from  the 
agencies.  Our  website  www.archgroup.com

We have large aggregate exposures to natural and man-made 
catastrophic  events,  pandemic  events  like  COVID-19  and 
severe  economic  events.  Natural  catastrophes  can  be  caused 
by  various  events,  including  hurricanes,  floods,  windstorms, 
earthquakes, hailstorms, tornadoes, explosions, severe winter 
weather, 
fires,  droughts  and  other  natural  disasters. 
Catastrophes  can  also  cause  losses  in  non-property  business 
such  as  mortgage  insurance,  workers’  compensation  or 
general  liability.  In  addition  to  the  nature  of  property 
business,  we  believe  that  economic  and  geographic  trends 
affecting insured property, including inflation, property value 
appreciation and geographic concentration, tend to generally 
increase the size of losses from catastrophic events over time.

We  have  substantial  exposure  to  unexpected,  large  losses 
resulting from future man-made catastrophic events, such as 
acts  of  war,  acts  of  terrorism  and  political  instability.  These 
risks are inherently unpredictable. It is difficult to predict the 
timing of such events with statistical certainty or estimate the 
amount  of  loss  any  given  occurrence  will  generate.  It  is  not 
possible 
to 
unforecasted  or  unpredictable  events  and,  to  the  extent  that 
losses  from  such  risks  occur,  our  financial  condition  and 
results  of  operations  could  be  materially  adversely  affected. 
Therefore,  claims  for  natural  and  man-made  catastrophic 
events  could  expose  us  to  large  losses  and  cause  substantial 
volatility in our results of operations, which could cause the 
value  of  our  common  shares  to  fluctuate  widely.  In  certain 
instances,  we  specifically  insure  and  reinsure  risks  resulting 
from  terrorism.  Even  in  cases  where  we  attempt  to  exclude 
losses  from  terrorism  and  certain  other  similar  risks  from 
some  coverages  written  by  us,  we  may  not  be  successful  in 
doing  so.  Moreover, 
the  clarity  and 
inclusiveness  of  policy  language,  there  can  be  no  assurance 
that  a  court  or  arbitration  panel  will  limit  enforceability  of 
policy language or otherwise issue a ruling adverse to us.

We  seek  to  limit  our  loss  exposure  by  writing  a  number  of 
our reinsurance contracts on an excess of loss basis, adhering 
to  maximum  limitations  on  reinsurance  written  in  defined 
geographical zones, limiting program size for each client and 
prudent underwriting of each program written. In the case of 
proportional treaties, we may seek per occurrence limitations 
or loss ratio caps to limit the impact of losses from any one or 
series of events. In our insurance operations, we seek to limit 
our exposure through the purchase of reinsurance. We cannot 
be  certain  that  any  of  these  loss  limitation  methods  will  be 
effective.  We  also  seek  to  limit  our  loss  exposure  by

be no assurance that various provisions of our policies, such 
as  limitations  or  exclusions  from  coverage  or  choice  of 
forum, will be enforceable in the manner we intend. Disputes 
relating to coverage and choice of legal forum may also arise. 
Underwriting  is  inherently  a  matter  of  judgment,  involving 
important  assumptions  about  matters  that  are  inherently 
unpredictable  and  beyond  our  control,  and  for  which 
historical  experience  and  probability  analysis  may  not 
provide  sufficient  guidance.  One  or  more  catastrophic  or 
other  events  could  result  in  claims  that  substantially  exceed 
our expectations, which could have a material adverse effect 
on  our  financial  condition  or  our  results  of  operations, 
possibly to the extent of eliminating our shareholders' equity.

For  our  natural  catastrophe  exposed  business,  we  seek  to 
limit  the  amount  of  exposure  we  will  assume  from  any  one 
insured  or  reinsured  and  the  amount  of  the  exposure  to 
catastrophe  losses  from  a  single  event  in  any  geographic 
zone.  We  monitor  our  exposure  to  catastrophic  events, 
including  earthquake  and  wind  and  periodically  reevaluate 
the  estimated  probable  maximum  pre-tax  loss  for  such 
exposures.  Our  estimated  probable  maximum  pre-tax  loss  is 
determined through the use of modeling techniques, but such 
estimate  does  not  represent  our  total  potential  loss  for  such 
exposures. 

Our  models  employ  both  proprietary  and  vendor-based 
systems  and  include  cross-line  correlations  for  property, 
marine, offshore energy, aviation, workers compensation and 
personal  accident.  We  seek  to  limit  the  probable  maximum 
pre-tax loss to a specific level for severe catastrophic events. 
Currently,  we  seek  to  limit  our  1-in-250  year  return  period 
net probable maximum loss from a severe catastrophic event 
in  any  geographic  zone  to  approximately  25%  of  tangible 
shareholders’  equity  available  to  Arch  (total  shareholders’ 
equity available to Arch less goodwill and intangible assets). 
We reserve the right to change this threshold at any time.

Based on in-force exposure estimated as of January 1, 2024, 
our modeled peak zone catastrophe exposure is a windstorm 
affecting  the  Florida  Tri-County,  with  a  net  probable 
maximum  pre-tax 
loss  of  $1.6  billion,  followed  by 
windstorms  affecting  the  Northeast  U.S.,  and  the  Gulf  of 
Mexico  with  net  probable  maximum  pre-tax  losses  of  $1.4 
billion and $1.3 billion, respectively. As of January 1, 2024, 
our  modeled  peak  zone  earthquake  exposure  (San  Francisco 
area earthquake) represented approximately 54% of our peak 
zone  catastrophe  exposure,  and  our  modeled  peak  zone 
international exposure (German windstorm) was substantially 
less  than  both  our  peak  zone  windstorm  and  earthquake 
exposures.

We also have significant exposure to losses due to mortgage 
defaults resulting from severe economic events in the future. 
For  our  U.S.  mortgage 
insurance  business,  we  have 
developed  a  proprietary  risk  model  (“Realistic  Disaster 

Scenario”  or  “RDS”)  that  simulates  the  maximum  loss 
resulting  from  a  severe  economic  downturn  impacting  the 
housing  market.  The  RDS  models  the  collective  impact  of 
adverse  conditions  for  key  economic  indicators,  the  most 
significant  of  which  is  a  decline  in  home  prices.  The  RDS 
model  projects  paths  of  future  home  prices,  unemployment 
rates, 
interest  rates  and  assumes 
correlation  across  states  and  geographic  regions.  The 
resulting future performance of our in-force portfolio is then 
estimated under the economic stress scenario, reflecting loan 
and borrower information.

levels  and 

income 

Currently,  we  seek  to  limit  our  modeled  RDS  loss  from  a 
severe  economic  event  to  approximately  25%  of  total 
tangible  shareholders’  equity  available  to  Arch.  We  reserve 
the  right  to  change  this  threshold  at  any  time.  Based  on  in-
force exposure estimated as of January 1, 2024, our modeled 
RDS loss was 7.0% of tangible shareholders’ equity available 
to Arch.

Net  probable  maximum  loss  estimates  are  net  of  expected 
reinsurance  recoveries,  before  income  tax  and  before  excess 
reinsurance reinstatement premiums. RDS loss estimates are 
net of expected reinsurance recoveries and before income tax. 
Catastrophe loss estimates are reflective of the zone indicated 
and not the entire portfolio. Since hurricanes and windstorms 
can  affect  more  than  one  zone  and  make  multiple  landfalls, 
our  catastrophe  loss  estimates  include  clash  estimates  from 
other  zones.  Our  catastrophe  loss  estimates  and  RDS  loss 
estimates do not represent our maximum exposures and it is 
highly  likely  that  our  actual  incurred  losses  would  vary 
materially  from  the  modeled  estimates.  There  can  be  no 
assurances that we will not suffer pre-tax losses greater than 
25%  of  our  tangible  shareholders’  equity  from  one  or  more 
catastrophic events or severe economic events due to several 
factors, including the inherent uncertainties in estimating the 
frequency and severity of such events and the margin of error 
in  making  such  determinations  resulting  from  potential 
inaccuracies and inadequacies in the data provided by clients 
and  brokers,  the  modeling  techniques  and  the  application  of 
such  techniques  or  as  a  result  of  a  decision  to  change  the 
percentage  of  shareholders'  equity  exposed  to  a  single 
catastrophic  event  or  severe  economic  event.  In  addition, 
actual losses may increase if our reinsurers fail to meet their 
obligations to us or the reinsurance protections purchased by 
us are exhausted or are otherwise unavailable. See Item 1A, 
“Risk Factors—Risks Relating to Our Industry, Business and 
Operations”  Depending  on  business  opportunities  and  the 
mix of business that may comprise our insurance, reinsurance 
and  mortgage  portfolios,  we  may  seek  to  adjust  our  self-
imposed  limitations  on  probable  maximum  pre-tax  loss  for 
catastrophe  exposed  business  and  mortgage  default  exposed 
business. See “—Summary of Critical Accounting Estimates
—Ceded  Reinsurance”  for  a  discussion  of  our  catastrophe 
reinsurance programs.

MARKET SENSITIVE INSTRUMENTS AND RISK 
MANAGEMENT

Our  investment  results  are  subject  to  a  variety  of  risks, 
including  risks  related  to  changes  in  the  business,  financial 
condition or results of operations of the entities in which we 
invest, as well as changes in general economic conditions and 
overall  market  conditions.  We  are  also  exposed  to  potential 
loss  from  various  market  risks,  including  changes  in  equity 
prices, interest rates and foreign currency exchange rates.

In  accordance  with  the  SEC’s  Financial  Reporting  Release 
No. 48, we performed a sensitivity analysis to determine the 
effects  that  market  risk  exposures  could  have  on  the  future 
earnings,  fair  values  or  cash  flows  of  our  financial 
instruments as of December 31, 2023. Market risk represents 
the risk of changes in the fair value of a financial instrument 
and consists of several components, including liquidity, basis 
and price risks. 

The sensitivity analysis performed as of December 31, 2023 
presents  hypothetical  losses  in  cash  flows,  earnings  and  fair 
values of market sensitive instruments which were held by us 
on December 31, 2023 and are sensitive to changes in interest 
rates  and  equity  security  prices.  This  risk  management 
discussion  and  the  estimated  amounts  generated  from  the 
following  sensitivity  analysis  represent  forward-looking 
statements  of  market  risk  assuming  certain  adverse  market 
conditions  occur.  Actual  results  in  the  future  may  differ 
materially  from 
to  actual 
developments  in  the  global  financial  markets.  The  analysis 
methods used by us to assess and mitigate risk should not be 
considered projections of future events of losses.

The focus of the SEC’s market risk rules is on price risk. For 
purposes  of  specific  risk  analysis,  we  employ  sensitivity 
analysis  to  determine  the  effects  that  market  risk  exposures 
could have on the future earnings, fair values or cash flows of 
our financial instruments. The financial instruments included 
in  the  following  sensitivity  analysis  consist  of  all  of  our 
investments and cash.

Investment Market Risk

Fixed  Income  Securities.  We  invest  in  interest  rate  sensitive 
securities, primarily debt securities. We consider the effect of 
interest  rate  movements  on  the  fair  value  of  our  fixed 
maturities,  short-term  investments  and  certain  of  our  other 
investments,  equity 
funds 
securities  and 
accounted for using the equity method which invest in fixed 
income  securities  (collectively,  “Fixed  Income  Securities”) 
and the corresponding change in unrealized appreciation. As 
interest  rates  rise,  the  fair  value  of  our  Fixed  Income 
Securities  falls,  and  the  converse  is  also  true.  Based  on 
historical  observations,  there  is  a  low  probability  that  all 

investment 

interest rate yield curves would shift in the same direction at 
the same time. Furthermore, at times interest rate movements 
in  certain  credit  sectors  exhibit  a  much  lower  correlation  to 
changes  in  U.S.  Treasury  yields.  Accordingly,  the  actual 
effect of interest rate movements may differ materially from 
the amounts set forth in the following tables. 

The following table summarizes the effect that an immediate, 
parallel shift in the interest rate yield curve would have had 
on our investment portfolio at December 31, 2023 and 2022:

In  addition,  we  consider 
the  effect  of  credit  spread 
movements  on  the  market  value  of  our  Fixed  Income 
Securities and the corresponding change in unrealized value. 
As credit spreads widen, the fair value of our Fixed Income 
Securities  falls,  and  the  converse  is  also  true.  In  periods 
where the spreads on our Fixed Income Securities are much 
higher than their historical average due to short-term market 
dislocations,  a  parallel  shift  in  credit  spread  levels  would 
result  in  a  much  more  pronounced  change  in  unrealized 
value.

Investment-Related  Derivatives.  At  December  31,  2023,  the 
notional  value  of  all  derivative  instruments  (excluding 
foreign currency forward contracts which are included in the 
foreign  currency  exchange  risk  analysis  below)  was  $4.2 
billion, compared to $6.6 billion at December 31, 2022. If the 
underlying  exposure  of  each  investment-related  derivative 
held at December 31, 2023 depreciated by 100 basis points, it 
would  have  resulted  in  a  reduction  in  net  income  of 
approximately $42 million, and a decrease in book value per 
share  of  $0.11,  compared  to  $66  million  and  $0.18, 
respectively,  on 
investment-related  derivatives  held  at 
December  31,  2022.  If  the  underlying  exposure  of  each 
investment-related  derivative  held  at  December  31,  2023 
appreciated by 100 basis points, it would have resulted in an 
increase in net income of approximately $42 million, and an 
increase  in  book  value  per  share  of  $0.11,  compared  to  $66 
million  and  $0.18,  respectively,  on 
investment-related 
derivatives  held  at  December  31,  2022.  See  note  11, 
“Derivative  Instruments,”  to  our  consolidated  financial 
statements  in  Item  8  for  additional  disclosures  concerning 
derivatives.

For further discussion on investment activity, please refer to 
“—Financial  Condition,  Liquidity  and  Capital  Resources—
Financial Condition—Investable Assets.”

Another  method  that  attempts  to  measure  portfolio  risk  is 
Value-at-Risk  (“VaR”).  VaR  measures  the  worst  expected 
loss  under  normal  market  conditions  over  a  specific  time 
interval  at  a  given  confidence  level.  The  1-year  95th 
percentile parametric VaR reported herein estimates that 95% 
of the time, the portfolio loss in a one-year horizon would be 
less  than  or  equal  to  the  calculated  number,  stated  as  a 
percentage of the measured portfolio’s initial value. The VaR 
is  a  variance-covariance  based  estimate,  based  on  linear 
sensitivities of a portfolio to a broad set of systematic market 
risk  factors  and  idiosyncratic  risk  factors  mapped  to  the 
portfolio  exposures.  The  relationships  between  the  risk 
factors  are  estimated  using  historical  data,  and  the  most 
recent  data  points  are  generally  given  more  weight.  As  of 
December 31, 2023, our portfolio’s 95th percentile VaR was 
estimated  to  be  7.8%,  compared  to  an  estimated  8.8%  at 
December 31, 2022. In periods where the volatility of the risk 
factors mapped to our portfolio’s exposures is higher due to 
market  conditions,  the  resulting  VaR  is  higher  than  in  other 
periods.

Equity  Securities.  At  December  31,  2023  and  2022,  the  fair 
value  of  our  investments  in  equity  securities  and  certain 
investments  accounted  for  using  the  equity  method  with 
underlying  equity  strategies  totaled  $1.0  billion  and  $0.8 
billion, respectively. These investments are exposed to price 
risk, which is the potential loss arising from decreases in fair 
value. An immediate hypothetical 10% decline in the value of 
each position would reduce the fair value of such investments 
by  approximately  $101  million  and  $79  million  at 
December 31, 2023 and 2022, respectively, and would have 
decreased book value per share by approximately  $0.27 and 
$0.21, respectively. An immediate hypothetical 10% increase 
in the value of each position would increase the fair value of 
such  investments  by  approximately  $101  million  and  $79 
million  at  December  31,  2023  and  2022,  respectively,  and 
would have increased book value per share by approximately 
$0.27 and $0.21, respectively.

Foreign Currency Exchange Risk

Foreign  currency  rate  risk  is  the  potential  change  in  value, 
income  and  cash  flow  arising  from  adverse  changes  in 
foreign  currency  exchange  rates.  Through  our  subsidiaries 
and branches located in various foreign countries, we conduct 
our insurance and reinsurance operations in a variety of local 
currencies  other  than  the  U.S.  Dollar.  We  generally  hold 
investments  in  foreign  currencies  which  are  intended  to 
mitigate our exposure to foreign currency fluctuations in our 
net insurance liabilities. We may also utilize foreign currency 
forward  contracts  and  currency  options  as  part  of  our 
investment  strategy.  See  note  11,  “Derivative  Instruments,” 
to  our  consolidated  financial  statements  in  Item  8  for

Although  the  Company  generally  attempts  to  match  the 
currency  of  its  projected  liabilities  with  investments  in  the 
same currencies, from time to time the Company may elect to 
over  or  underweight  one  or  more  currencies,  which  could 
increase 
to  foreign  currency 
fluctuations  and  increase  the  volatility  of  the  Company’s 
shareholders’  equity.  Historical  observations  indicate  a  low 
probability  that  all  foreign  currency  exchange  rates  would 
shift against the U.S. Dollar in the same direction and at the 
same  time  and,  accordingly,  the  actual  effect  of  foreign 
currency  rate  movements  may  differ  materially  from  the 
amounts  set  forth  above.  For  further  discussion  on  foreign 
exchange activity, please refer to “—Results of Operations.”

Effects of Inflation

General  economic  inflation  has  increased  in  recent  quarters 
and may continue to remain at elevated levels for an extended 
period  of  time.  The  potential  also  exists,  after  a  catastrophe 
loss or pandemic events like COVID-19, for the development 
of inflationary pressures in a local economy. This may have a 
material effect on the adequacy of our reserves for losses and 
loss adjustment expenses, especially in longer-tailed lines of 
business, and on the market value of our investment portfolio 
through  rising  interest  rates.  The  anticipated  effects  of 
inflation  are  considered  in  our  pricing  models,  reserving 
processes  and  exposure  management,  across  all  lines  of 
business  and  types  of  loss  including  natural  catastrophe 
events. The actual effects of inflation on our results cannot be 
accurately known until claims are ultimately settled and will 
vary  by  the  specific  type  of  inflation  affecting  each  line  of 
business.

Report of Independent Registered Public Accounting Firm 

To the Board of Directors and Shareholders of Arch Capital Group Ltd. 

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Arch Capital Group Ltd. and its subsidiaries (the 
“Company”) as of December 31, 2023 and 2022, and the related consolidated statements of income, of comprehensive income, 
of changes in shareholders’ equity and of cash flows for each of the three years in the period ended December 31, 2023, 
including the related notes and financial statement schedules listed in the index appearing under Item 15(a)(2) (collectively 
referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial 
reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by 
the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial 
position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the 
three years in the period ended December 31, 2023 in conformity with accounting principles generally accepted in the United 
States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over 
financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) 
issued by the COSO. 

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal 
control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included 
in Management’s Annual Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to 
express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial 
reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight 
Board (United States) (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 
audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, 
whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material 
respects.

Our audits of the consolidated financial statements 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. Our audit of internal 
control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the 
risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based 
on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the 
circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the 
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally 
accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures 
that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit 
preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and 
expenditures of the company are being made only in accordance with authorizations of management and directors of the 
company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or 
disposition of the company’s assets that could have a material effect on the financial statements.

ARCH CAPITAL

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial 
statements that were communicated or required to be communicated to the audit committee and that (i) relate to accounts or 
disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or 
complex judgments. The communication of critical audit matters 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 matters below, providing separate 
opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Valuation of Reserve for Losses and Loss Adjustment Expenses

As described in Notes 3, 5 and 6 to the consolidated financial statements, the reserve for losses and loss adjustment expenses 
represents estimates of future amounts required to pay losses and loss adjustment expenses for insured or reinsured events 
which have occurred at or before the balance sheet date. As of December 31, 2023, the Company’s total reserve for losses and 
loss adjustment expenses was $22.8 billion. For the insurance and reinsurance segments, management estimates ultimate losses 
and loss adjustment expenses using various generally accepted actuarial methods applied to known losses and other relevant 
information. Ultimate losses and loss adjustment expenses are generally determined by extrapolation of claim emergence and 
settlement patterns observed in the past that can reasonably be expected to persist into the future. Management makes a number 
of key assumptions in their reserving process, including estimating loss development patterns and expected loss ratios. For the 
mortgage segment, the lead actuarial methodology used by management is a frequency-severity method based on the inventory 
of pending delinquencies. The assumptions of frequency and severity reflect judgments based on historical data and experience. 

The principal considerations for our determination that performing procedures relating to the valuation of the reserve for losses 
and loss adjustment expenses is a critical audit matter are (i) the significant judgment by management when developing their 
estimate, (ii) a high degree of auditor judgment, subjectivity and effort in performing procedures and evaluating audit evidence 
relating to the aforementioned key actuarial methods and key assumptions, and (iii) the audit effort involved the use of 
professionals with specialized skill and knowledge. 

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall 
opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the 
valuation of the reserve for losses and loss adjustment expenses, including controls over the selection of key actuarial methods 
and development of key assumptions. These procedures also included, among others, the involvement of professionals with 
specialized skill and knowledge to assist in performing one or a combination of procedures, including (i) developing an 
independent estimate, on a test basis, of the reserve for losses and loss adjustment expenses, and comparing the independent 
estimate to management’s actuarially determined reserve for losses and loss adjustment expenses to evaluate the reasonableness 
of the reserve for losses and loss adjustment expenses and (ii) evaluating the appropriateness of the actuarial methods and 
reasonableness of the assumptions related to loss development patterns, expected loss ratios, frequency, and severity used by 
management to determine the Company’s reserve for losses and loss adjustment expenses. Developing the independent estimate 
and evaluating the appropriateness of the key methods and reasonableness of the key assumptions related to loss development 
patterns, expected loss ratios, frequency and severity, as applicable, involved testing the completeness and accuracy of 
historical data provided by management.

Measurement of Deferred Tax Assets related to Certain Identifiable Intangible Assets in Bermuda Entities

As described in Note 15 to the consolidated financial statements, as of December 31, 2023, the Company recognized $1.2 
billion in net deferred tax assets related to the Bermuda government’s enactment of the Bermuda Corporate Income Tax Act 
2023. As disclosed by management, the enacted legislation includes a provision referred to as the Economic Transition 
Adjustment, which requires Bermuda entities to establish tax basis in their assets and liabilities, excluding goodwill, based on 
fair value as of September 30, 2023. The most significant deferred tax assets recognized relates to identifiable intangible assets. 
Management estimated the fair value of the identifiable intangible assets using discounted cash flow models. The significant 
assumptions utilized in the discounted cash flow models included the future revenue and profits expected to be generated by the 
identifiable intangible assets and the discount rates. 

The principal considerations for our determination that performing procedures relating to the measurement of deferred tax 
assets related to certain identifiable intangible assets in Bermuda entities is a critical audit matter are (i) the significant judgment 
by management when developing the fair value estimate of certain identifiable intangible assets, (ii) a high degree of auditor 
judgment, subjectivity and effort in performing procedures and evaluating management’s significant assumptions related to the 
future revenue and profits expected to be generated by the certain identifiable intangible assets and the discount rates, and (iii) 
the audit effort involved the use of professionals with specialized skill and knowledge. 

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall 
opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the 
enactment of the Bermuda Corporate Income Tax Act 2023 including controls over the valuation of certain identifiable 
intangible assets related to the enactment of the Bermuda Corporate Income Tax Act 2023. These procedures also included, 
among others, (i) testing management’s process for developing the fair value estimate of the certain identifiable intangible 
assets, (ii) evaluating the appropriateness of the discounted cash flow models used by management, (iii) testing the 
completeness and accuracy of the data used in the models, and (iv) evaluating the reasonableness of the significant assumptions 
used by management related to the future revenue and profits expected to be generated by the certain identifiable intangible 
assets and the discount rates. Evaluating management’s assumptions related to the future revenue and profits expected to be 
generated by the identifiable intangible assets involved evaluating whether the assumptions used were reasonable considering 
(i) the consistency with historical revenue and profits generated by the Bermuda entities and (ii) whether the assumptions were
consistent with evidence obtained in other areas of the audit. Professionals with specialized skill and knowledge were used to
assist in evaluating (i) the appropriateness of the discounted cash flow models and (ii) the reasonableness of the discount rate
assumptions.

(b) Premium Revenues and Related Expenses

Insurance. 
Insurance  premiums  written  are  generally 
recorded at the policy inception and are primarily earned on a 
pro rata basis over the terms of the policies for all products, 
usually  12  months.  Premiums  written  include  estimates  that 
are  derived  from  multiple  sources  which

historical  experience  of  the  underlying  business,  similar 
business  and  available 
information.  Unearned

policies.

the  reported 

Reinsurance. Reinsurance premiums written include amounts 
reported by brokers and ceding companies, supplemented by 
the  Company’s  own  estimates  of  premiums  where  reports 
have  not  been  received.  The  determination  of  premium 
estimates  requires  a  review  of  the  Company’s  experience 
with the ceding companies, familiarity with each market, the 
timing  of 
information,  an  analysis  and 
understanding of the characteristics of each line of business, 
and management’s judgment of the impact of various factors, 
including premium or loss trends, on the volume of business 
written and ceded to the Company. On an ongoing basis, the 
Company’s  underwriters  review  the  amounts  reported  by 
these 
their 
third  parties  for  reasonableness  based  on 
experience  and  knowledge  of  the  subject  class  of  business, 
taking into account the Company’s historical experience with 
the  brokers  or  ceding  companies.  In  addition,  reinsurance 
contracts  under  which  the  Company  assumes  business 
the 
generally  contain  specific  provisions  which  allow 
Company to perform audits of the ceding company to ensure 
compliance  with  the  terms  and  conditions  of  the  contract, 
including accurate and timely reporting of information. Based 
on  a  review  of  all  available  information,  management 
establishes  premium  estimates  where  reports  have  not  been 
received.  Premium  estimates  are  updated  when  new 
information 
is  received  and  differences  between  such 
estimates  and  actual  amounts  are  recorded  in  the  period  in 
which  estimates  are  changed  or  the  actual  amounts  are 
determined.

Reinsurance premiums written are recorded based on the type 
the 
of  contracts 
Company’s excess of loss and pro rata reinsurance contracts 
are  estimated  when  the  business  is  underwritten.  For  excess 
of loss contracts, premiums are recorded as written based on 

the  brokers  and 

the  terms  of  the  contract.  Estimates  of  premiums  written 
under  pro  rata  contracts  are  recorded  in  the  period  in  which 
the underlying risks are expected to incept and are based on 
information  provided  by 
the  ceding 
companies.  For  multi-year  reinsurance  treaties  which  are 
payable  in  annual  installments,  generally,  only  the  initial 
annual installment is included as premiums written at policy 
inception  due  to  the  ability  of  the  reinsured  to  commute  or 
cancel coverage during the term of the policy. The remaining 
annual installments are included as premiums written at each 
successive anniversary date within the multi-year term.

Reinsurance  premiums  written,  irrespective  of  the  class  of 
business,  are  generally  earned  on  a  pro  rata  basis  over  the 
terms  of  the  underlying  policies  or  reinsurance  contracts. 
Contracts  and  policies  written  on  a  “losses  occurring”  basis 
cover  claims  that  may  occur  during  the  term  of  the  contract 
or  policy,  which  is  typically  12  months.  Accordingly,  the 
premium is earned evenly over the term. Contracts which are 
written on a “risks attaching” basis cover claims which attach 
to the underlying insurance policies written during the terms 
of such contracts. Premiums earned on such contracts usually 
extend  beyond  the  original  term  of  the  reinsurance  contract, 
typically resulting in recognition of premiums earned over a 
24-month  period.  Certain  of  the  Company’s  reinsurance
contracts 
that  adjust  premiums  or
acquisition  expenses  based  upon  the  experience  under  the
contracts.  Premiums  written  and  earned,  as  well  as  related
acquisition  expenses,  are  recorded  based  upon  the  projected
experience under such contracts.

The Company also writes certain reinsurance business that is 
intended to provide insurers with risk management solutions 
that  complement 
these 
contracts,  the  Company  assumes  a  measured  amount  of 
insurance  risk  in  exchange  for  an  anticipated  margin,  which 
is  typically  lower  than  on  traditional  reinsurance  contracts. 
The  terms  and  conditions  of  these  contracts  may  include 
additional or return premiums based on loss experience, loss 
corridors,  sublimits  and  caps.  Examples  of  such  business 
include  aggregate  stop-loss  coverages,  financial  quota  share 
coverages and multi-year retrospectively rated excess of loss 
coverages. If these contracts are deemed to transfer risk, they 
are  accounted  for  as  reinsurance.  Otherwise,  such  contracts 
are accounted for under the deposit method.

insurance  policies  are 
contracts that are generally non-cancelable by the insurer, are 
renewable  at  a  fixed  price,  and  provide  for  payment  of 
premiums  on  a  monthly,  annual  or  single  basis.  Upon 
renewal, the Company is not able to re-underwrite or re-price 
its  policies.  Consistent  with  industry  accounting  practices, 
premiums written on a monthly basis are earned as coverage 
is  provided.  Premiums  written  on  an  annual  basis  are 
amortized  on  a  monthly  pro  rata  basis  over  the  year  of 
coverage.  Primary  mortgage  insurance  premiums  written  on

policies covering more than one year are referred to as single 
premiums. A portion of the revenue from single premiums is 
recognized in premiums earned in the current period, and the 
remaining  portion  is  deferred  as  unearned  premiums  and 
earned over the estimated expiration of risk of the policy. If 
single premium policies related to insured loans are canceled 
due  to  repayment  by  the  borrower  and  the  policy  is  a  non-
refundable product, the remaining unearned premium related 
to  each  canceled  policy  is  recognized  as  earned  premium 
upon notification of the cancellation. 

counterparty financial strength measures. The allowance also 
includes  estimated  uncollectible  amounts  related  to  dispute 
risk.  In  certain  instances,  credit  risk  may  be  reduced  by  the 
Company’s  right  to  offset  loss  obligations  or  unearned 
premiums  against  premiums  receivable.  Any  allowance  for 
credit  losses  is  charged  to  net  realized  gains  (losses)  in  the 
period  the  receivable  is  recorded  and  revised  in  subsequent 
periods  to  reflect  changes  in  the  Company’s  estimate  of 
expected credit losses. See note 7, “Allowance for Expected 
Credit Losses” for additional information.

Unearned premiums for the Company’s mortgage operations 
represent the portion of premiums written that is applicable to 
the  estimated  unexpired  risk  of  insured  loans.  A  portion  of 
premium payments may be refundable if the insured cancels 
coverage, which generally occurs when the loan is repaid, the 
loan amortizes to a sufficiently low amount to trigger a lender 
permitted or legally required cancellation, or the value of the 
property  has  increased  sufficiently  in  accordance  with  the 
terms  of  the  contract.  Premium  refunds  reduce  premiums 
earned  in  the  consolidated  statements  of  income.  Generally, 
only unearned premiums are refundable.

Reinstatement  premiums  for  the  Company’s  insurance  and 
reinsurance operations are recognized at the time a loss event 
occurs,  where  coverage  limits  for  the  remaining  life  of  the 
contract  are  reinstated  under  pre-defined  contract  terms. 
Reinstatement premiums, if obligatory, are fully earned when 
recognized.  The  accrual  of  reinstatement  premiums  is  based 
on an estimate of losses and loss adjustment expenses, which 
reflects management’s judgment. 

Premium  estimates  are  reviewed  by  management  at  least 
quarterly.  Such  review  includes  a  comparison  of  actual 
reported premiums to expected ultimate premiums along with 
a  review  of  the  aging  and  collection  of  premium  estimates. 
Based  on  management’s  review,  the  appropriateness  of  the 
premium estimates is evaluated, and any adjustment to these 
estimates  is  recorded  in  the  period  in  which  it  becomes 
known. Adjustments to premium estimates could be material 
and such adjustments could directly and significantly impact 
earnings  favorably  or  unfavorably  in  the  period  they  are 
determined  because  the  estimated  premium  may  be  fully  or 
substantially  earned.  A  significant  portion  of  amounts 
included  as  premiums  receivable,  which  represent  estimated 
premiums written, net of commissions, are not currently due

Acquisition  Costs.  Acquisition  costs  that  are  directly  related 
and  incremental  to  the  successful  acquisition  or  renewal  of 
business  are  deferred  and  amortized  based  on  the  type  of 
reinsurance 
contract.  The  Company’s 
operations  capitalize  incremental  direct  external  costs  that 
result from acquiring a contract but do not capitalize salaries, 
benefits  and  other  internal  underwriting  costs.  For  the 
Company’s  mortgage  insurance  operations,  which  include  a 
substantial  direct  sales  force,  both  external  and  certain 
internal direct costs are deferred and amortized. For property 
and  casualty  insurance  and  reinsurance  contracts,  deferred 
acquisition  costs  are  amortized  over  the  period  in  which  the 
related  premiums  are  earned.  Consistent  with  mortgage 
insurance  industry  accounting  practice,  amortization  of 
acquisition costs related to the mortgage insurance contracts 
for each underwriting year’s book of business is recorded in 
proportion to estimated gross profits. Estimated gross profits 
are  comprised  of  earned  premiums  and  losses  and  loss

Deferred  acquisition  costs  are  carried  at  their  estimated

experience, and anticipated investment income. 

A premium deficiency occurs if the sum of anticipated losses 
and  loss  adjustment  expenses,  unamortized  acquisition  costs 
and maintenance costs exceed unearned premiums (including 
expected  future  premiums)  and  anticipated 
investment 
income.  A  premium  deficiency  reserve  (“PDR”)  is  recorded 
by charging any unamortized acquisition costs to expense to 
the extent required in order to eliminate the deficiency. If the 
premium  deficiency  exceeds  unamortized  acquisition  costs 
then a liability is accrued for the excess deficiency. 

To  assess  the  need  for  a  PDR  on  mortgage  exposures,  the 
Company  develops  loss  projections  based  on  modeled  loan 
defaults related to its current policies in force. This projection 
is  based  on  recent  trends  in  default  experience,  severity  and 
rates  of  defaulted  loans  moving  to  claim,  as  well  as  recent 
trends in the rate at which loans are prepaid, and incorporates

profitability  of  the  Company’s  existing  mortgage  insurance 
business  and  the  need  for  a  PDR  for  its  mortgage  business 
involves significant reliance upon assumptions and estimates 
with  regard  to  the  likelihood,  magnitude  and  timing  of 
potential 
losses  and  premium  revenues.  No  premium

Certain assumed reinsurance contracts that are deemed not to

assumptions  used  in  determining  whether  assumed  contracts 
should  be  accounted  for  as  reinsurance  contracts  or  deposit 
contracts.  For  those  contracts  that  contain  only  significant 
underwriting risk, the estimated profit margin is deferred and 
amortized  over  the  contract  period  and  such  amount  is 
included  in  the  Company’s  underwriting  results.  When  the 
estimated profit margin is explicit, the margin is reflected as 
other  underwriting  income  and  any  adverse  financial  results 
on  such  contracts  are  reflected  as  incurred  losses.  When  the 
estimated profit margin is implicit, the margin is reflected as 
an  offset  to  paid  losses  and  any  adverse  financial  results  on 
such  contracts  are  reflected  as  incurred  losses.  Additional 
judgments  are  required  when  applying  the  accounting 
guidance  with  respect  to  the  revenue  recognition  criteria  for 
contracts  deemed  to  transfer  only  significant  underwriting 
risk.  For  those  contracts  that  contain  only  significant  timing 
risk,  an  accretion  rate  is  established  at  inception  of  the 
contract  based  on  actuarial  estimates  whereby  the  deposit

future  payment  obligations.  Periodically 

Under  some  of  these  contracts,  the  ceding  company  retains 
the  related  assets  on  a  funds  held  basis.  Such  amounts  are 
included  in  “Other  assets”  on  the  Company’s  balance  sheet. 
Interest income produced by those assets are recorded as part 
of  net  investment  income  in  the  Company's  results  of 
operations.

(d) Retroactive Reinsurance

Retroactive  reinsurance  reimburses  a  ceding  company  for 
liabilities incurred as a result of past insurable events covered 
by  the  underlying  policies  reinsured.  In  certain  instances, 
reinsurance contracts cover losses both on a prospective basis 
and  on  a  retroactive  basis  and,  accordingly,  the  Company 
bifurcates the prospective and retrospective elements of these 
reinsurance  contracts  and  accounts  for  each  element 
separately where practical. Underwriting income generated in 
connection  with  retroactive  reinsurance  contracts  is  deferred 
and  amortized  into  income  over  the  settlement  period  while 
losses  are  charged  to  income  immediately.  Subsequent 
changes  in  estimated  amount  or  timing  of  cash  flows  under 
such  retroactive  reinsurance  contracts  are  accounted  for  by 
adjusting the previously deferred amount to the balance that 
would have existed had the revised estimate been available at 
the 
transaction,  with  a 
corresponding charge or credit to income.

levels  of  risk  with  other 

In  the  normal  course  of  business,  the  Company  purchases 
reinsurance  to  increase  capacity  and  to  limit  the  impact  of 
individual  losses  and  events  on  its  underwriting  results  by 
reinsuring  certain 
insurance 
enterprises or reinsurers. The Company uses pro rata, excess 
of  loss  and  facultative  reinsurance  contracts.  Reinsurance 
ceding  commissions  that  represent  a  recovery  of  acquisition 
costs are recognized as a reduction to acquisition costs while 
the  remaining  portion 
is  deferred.  The  accompanying 
consolidated  statement  of  income  reflects  premiums  and 
losses and loss adjustment expenses and acquisition costs, net

allowance  for  credit  losses  is  charged  to  net  realized  gains 
(losses) in the period the recoverable is recorded and revised 
in  subsequent  periods  to  reflect  changes  in  the  Company’s 
estimate of expected credit losses. See note 7, “Allowance for 
Expected Credit Losses” for additional information.

(f) Cash

Cash  includes  cash  equivalents,  which  are  investments  with 
original maturities of three months or less which are not part 
of the investment portfolio.

(g) Restricted Cash

Restricted  cash  represents  amounts  held  for  the  benefit  of 
third  parties  or  is  legally  or  contractually  restricted  as  to 
withdrawal  or  usage  by  the  Company.  Such  amounts  are 
included in “Other assets” on the Company’s balance sheet.

(h) Investments

short-term 

investments  and 

The Company currently classifies substantially all of its fixed 
maturity 
investments  as 
“available  for  sale”  and,  accordingly,  they  are  carried  at 
estimated  fair  value  (also  known  as  fair  value)  with  the 
changes  in  fair  value  recorded  as  an  unrealized  gain  or  loss 
component  of  accumulated  other  comprehensive  income  in 
shareholders’  equity.  The  fair  value  of  fixed  maturity 
securities and equity securities is generally determined from 
quotations  received  from  nationally  recognized  pricing 
services, or when such prices are not available, by reference 
indications.  Short-term 
to  broker  or  underwriter  bid 
investments  comprise  securities  due  to  mature  within  one 
year  of  the  date  of  issue.  Short-term  investments  include 
certain  cash  equivalents  which  are  part  of  investment 
portfolios  under  the  management  of  external  and  internal 
investment managers.

The  Company’s  investment  portfolio  includes  certain  funds 
that,  due  to  their  ownership  structure,  are  accounted  for  by 
the Company using the equity method. In applying the equity 
method,  these  investments  are  initially  recorded  at  cost  and 
are  subsequently  adjusted  based  on 
the  Company’s 
proportionate  share  of  the  net  income  or  loss  of  the  funds 
(which  include  changes  in  the  fair  value  of  the  underlying 
securities  in  the  funds).  Such  investments  are  generally 
recorded on a one to three month lag based on the availability 
of reports from the investment funds. Changes in the carrying 
value  of  such  investments  are  recorded  in  net  income  as 
“Equity  in  net  income  (loss)  of  investments  accounted  for 
using  the  equity  method.”  As  such,  fluctuations  in  the 
carrying  value  of  the  investments  accounted  for  using  the 
equity method may increase the volatility of the Company’s 
reported results of operations.

The  Company’s 
includes  equity 
investment  portfolio 
securities that are accounted for at fair value. Such holdings 
primarily  include  publicly  traded  common  stocks.  Dividend 
income  on  equities  is  reflected  in  net  investment  income. 
Changes  in  fair  value  on  equity  securities  are  included  in 
“Net realized gains (losses)” in the consolidated statement of 
income.

The  Company  elected  to  carry  certain  fixed  maturity 
securities, equity securities, short-term investments and other 
investments at fair value under the fair value option afforded 
by  accounting  guidance  regarding  the  fair  value  option  for 
financial  assets  and  liabilities.  The  fair  value  for  certain  of 
the  Company’s  other  investments  are  determined  using  net 
asset values (“NAVs”) as advised by external fund managers. 
The  NAV  is  based  on  the  fund  manager’s  valuation  of  the 
underlying holdings in accordance with the fund’s governing 
documents.

Changes in fair value of investments accounted for using the 
fair value option are included in “Net realized gains (losses).” 
The primary reasons for electing the fair value option were to 
address simplification and cost-benefit considerations.

The  Company  invests  in  reverse  repurchase  agreements  that 
are  generally

Receivables  for  reverse  repurchase  agreements  are  reflected 
in  “Other  investments”  or  “Short-term  investments”  in  the 
Company's  consolidated  balance  sheet  depending  on  their

In 

The  Company  invests  in  limited  partner  interests  and  shares 
of limited liability companies. Such amounts are included in 
investments accounted for using the equity method and other 
investments. These investments can often have characteristics 
of a variable interest entity (“VIE”). A VIE refers to entities 
that have characteristics such as (i) insufficient equity at risk 
to allow the entity to finance its activities without additional 
financial support or (ii) instances where the equity investors, 
as  a  group,  do  not  have  the  characteristic  of  a  controlling 
financial  interest.  If  the  Company  is  determined  to  be  the 
primary beneficiary, it is required to consolidate the VIE. The 
primary beneficiary is defined as the variable interest holder 
that is determined to have the controlling financial interest as 
a result of having both (i) the power to direct the activities of 
a  VIE 
the  economic 
performance  of  the  VIE  and  (ii)  the  obligation  to  absorb 
losses  or  right  to  receive  benefits  from  the  VIE  that  could 
potentially be significant to the VIE. At inception of the VIE 
as  well  as  on  an  ongoing  basis,  the  Company  determines 
whether it is the primary beneficiary based on an analysis of 
the  Company’s  level  of  involvement  in  the  VIE,  the

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

contractual  terms,  and  the  overall  structure  of  the  VIE.  The 
Company's  maximum  exposure  to  loss  with  respect  to  these 
investments  is  limited  to  the  investment  carrying  amounts 
reported  in  the  Company's  consolidated  balance  sheet  and 
any unfunded commitment.

The  Company  conducts  a  periodic  review  to  identify  and 
evaluate  credit  based  impairments  related  to  the  Company’s 
available  for  sale 
investments.  The  Company  derives 
estimated  credit  losses  by  comparing  expected  future  cash 
flows  to  be  collected  to  the  amortized  cost  of  the  security. 
Estimates  of  expected  future  cash  flows  consider  among 
other  things,  macroeconomic  conditions  as  well  as  the 
financial condition, near-term and long-term prospects for the 
issuer,  and  the  likelihood  of  the  recoverability  of  principal 
and  interest.  Effective  January  1,  2020,  credit  losses  are 
recognized through an allowance account subject to reversal, 
rather  than  a  reduction  in  amortized  cost.  Declines  in  value 
attributable  to  factors  other  than  credit  are  reported  as  an 
unrealized  loss  in  other  comprehensive  income  while  the 
allowance  for  credit  loss  is  charged  to  net  realized  gains 
(losses) in the consolidated statement of income.

For available for sale investments that the Company intends 
to  sell  or  for  which  it  is  more  likely  than  not  that  the 
Company  would  be  required  to  sell  before  an  anticipated 
recovery  in  value,  the  full  amount  of  the  impairment  is 
included in net realized gains (losses). The new cost basis of 
the  investment  is  the  previous  amortized  cost  basis  reduced 
by  the  impairment  recognized  in  net  realized  gains  (losses). 
The  new  cost  basis  is  not  adjusted  for  any  subsequent 
recoveries in fair value. 

The Company reports accrued investment income separately 
from investment balances and has elected not to measure an 
allowance  for  credit  losses  for  accrued  investment  income. 
Any  uncollectible  accrued  interest  income  is  written  off  in 
the period it is deemed uncollectible.

Net investment income includes interest and dividend income 
together with amortization of market premiums and discounts 
and  is  net  of  investment  management  and  custody  fees. 
Anticipated prepayments and expected maturities are used in 
applying the interest method for certain investments such as 
mortgage  and  other  asset-backed  securities.  When  actual

net  investment  in  such  securities  is  adjusted  to  the  amount 
that  would  have  existed  had  the  new  effective  yield  been 
applied  since 
the  security.  Such 
adjustments,  if  any,  are  included  in  net  investment  income

certain  fund  investments  are  determined  on  an  average  cost 
basis.  Unrealized  appreciation  or  decline  in  the  value  of 
available for sale securities, which are carried at fair value, is 
excluded  from  net  income  and  recorded  as  a  separate 
component of accumulated other comprehensive income, net 
of applicable deferred income tax.

(i) Derivative Instruments

recognizes  all  derivative 

The  Company 
instruments, 
including  embedded  derivative  instruments,  at  fair  value  in 
its  consolidated  balance  sheets.  The  Company  employs  the 
use of derivative instruments within its operations to mitigate 
risks  arising  from  assets  and  liabilities  held  in  foreign 
currencies  as  well  as  part  of  its  overall  investment  strategy. 
For  such  instruments,  changes  in  assets  and  liabilities 
measured  at  fair  value  are  recorded  as  “Net  realized  gains 
(losses)”  in  the  consolidated  statements  of  income.  In 
addition,  the  Company’s  derivative  instruments  include 
amounts related to underwriting activities where an insurance 
or  reinsurance  contract  meets  the  accounting  definition  of  a 
derivative  instrument.  For  such  contracts,  changes  in  fair 
value  are  reflected  in  “Other  underwriting  income”  in  the 
consolidated statements of income as the underlying contract 
originates from the Company’s underwriting operations. For 
the  periods  ended  2023,  2022,  and  2021,  the  Company  did 
not designate any derivative instruments as hedges under the 
relevant  accounting  guidance.  See  note  11,  “Derivative 
Instruments” for additional information.

(j) Reserves for Losses and Loss Adjustment Expenses

Insurance  and  Reinsurance.  The  reserve  for  losses  and  loss 
adjustment expenses consists of estimates of unpaid reported 
losses and loss adjustment expenses and estimates for losses 
incurred  but  not  reported.  The  reserve  for  unpaid  reported 
losses  and 
loss  adjustment  expenses,  established  by 
management  based  on  reports  from  ceding  companies  and 
claims  from  insureds,  excludes  estimates  of  amounts  related 
to  losses  under  high  deductible  policies,  and  represents  the 
estimated ultimate cost of events or conditions that have been 
reported  to  or  specifically  identified  by  the  Company.  Such 
reserves  are  supplemented  by  management’s  estimates  of 
reserves for losses incurred for which reports or claims have 
not  been  received.  The  Company’s  reserves  are  based  on  a 
combination  of  reserving  methods, 
incorporating  both 
Company  and  industry  loss  development  patterns.  The 
Company selects the initial expected loss and loss adjustment 
its 
expense  ratios  based  on 
underwriters  and  actuaries  during  the  initial  pricing  of  the 
business,  supplemented  by  industry  data  where  appropriate. 
Such  ratios  consider,  among  other  things,  rate  changes  and 

information  derived  by

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

changes  in  terms  and  conditions  that  have  been  observed  in 
the  market.  These  estimates  are  reviewed  regularly  and,  as 
experience  develops  and  new  information  becomes  known, 
the  reserves  are  adjusted  as  necessary.  Such  adjustments,  if 
any,  are  reflected  in  income  in  the  period  in  which  they  are 
determined. As actual loss information has been reported, the 
Company  has  developed  its  own  loss  experience  and  its 
reserving  methods  include  other  actuarial  techniques.  Over 
time,  such  techniques  have  been  given  further  weight  in  its 
reserving  process  based  on  the  continuing  maturation  of  the 
Company’s  reserves.  Inherent  in  the  estimates  of  ultimate 
losses  and  loss  adjustment  expenses  are  expected  trends  in 
claims  severity  and  frequency  and  other  factors  which  may 
vary significantly as claims are settled. Accordingly, ultimate 
losses  and  loss  adjustment  expenses  may  differ  materially 
from the amounts recorded in the accompanying consolidated 
financial statements. Losses and loss adjustment expenses are 
recorded  on  an  undiscounted  basis,  except  for  excess 
workers’  compensation  and  employers’  liability  business 
written by the Company’s insurance operations.

Mortgage.  The  reserves  for  mortgage  guaranty  insurance 
losses  and  loss  adjustment  expenses  are  the  estimated  claim 
settlement  costs  on  notices  of  delinquency  that  have  been 
received by the Company, as well as loan delinquencies that 
have been incurred but have not been reported by the lenders. 
industry 
Consistent  with  primary  mortgage 
accounting  practice,  the  Company  does  not  establish  loss 
reserves  for  future  claims  on  insured  loans  that  are  not 
currently  delinquent  (defined  as  two  or  more  payments  in 
arrears). The Company establishes loss reserves on a case-by-
case  basis  when  insured  loans  are  reported  delinquent  using 
estimated claim rates and average claim sizes for each cohort, 
net  of  any  salvage  recoverable.  The  Company  also  reserves 
for  delinquencies  that  have  occurred  but  have  not  yet  been 
reported to the Company prior to the close of an accounting 
period. To determine this reserve, the Company estimates the 
number  of  delinquencies  not  yet  reported  using  historical 
information regarding late reported delinquencies and applies 
estimated  claim  rates  and  claim  sizes  for  the  estimated 
delinquencies not yet reported.

The  establishment  of  reserves  across 
the  Company’s 
segments  is  an  inherently  uncertain  process,  are  necessarily 
based on estimates, and the ultimate net cost may vary from 
such  estimates.  The  methods  for  making  such  estimates  and 
for  establishing  the  resulting  liability  are  reviewed  and 
updated  using  the  most  current  information  available.  Any 
resulting adjustments, which may be material, are reflected in 
current operations.

basis  in  the  consolidated  balance  sheet  as  contractholder 
payables and contractholder receivables. In the event that the 
Company  is  unable  to  collect  from  the  policyholder,  the 
Company  would  be  liable  for  such  defaulted  amounts. 
Collateral, primarily in the form of letters of credit, cash and 
trusts,  is  obtained  from  the  policyholder  to  mitigate  the 
Company’s  credit  risk.  In  the  instances  where  the  Company 
receives collateral in the form of cash, the Company reflects 
it in “Collateral held for insured obligations.”

probability-of-default 

Contractholder  receivables  are  reported  net  of  an  allowance 
for  expected  credit  losses.  The  allowance  is  based  upon  the 
Company’s ongoing review of amounts outstanding, changes 
in  policyholder  credit  standing,  amounts  and  form  of 
collateral  obtained,  and  other  relevant  factors.  A  ratings 
based 
loss-given-default 
methodology  is  used  to  estimate  the  allowance  for  expected 
credit  losses.  Any  allowance  for  credit  losses  is  charged  to 
net  realized  gains  (losses)  in  the  period  the  receivable  is 
recorded and revised in subsequent periods to reflect changes 
in the Company’s estimate of expected credit losses. See note 
7,  “Allowance  for  Expected  Credit  Losses”  for  additional 
information.

and 

(l) Foreign Exchange

Assets  and  liabilities  of  foreign  operations  whose  functional 
currency is not the U.S. Dollar are translated at the prevailing 
exchange  rates  at  each  balance  sheet  date.  Revenues  and 
expenses of such foreign operations are translated at average 
exchange  rates  during  the  year.  The  net  effect  of  the 
translation  adjustments  for  foreign  operations  is  included  in 
accumulated  other  comprehensive  income,  net  of  applicable 
deferred income tax. Monetary assets and liabilities, such as 
premiums  receivable  and  the  reserve  for  losses  and  loss 
adjustment  expenses,  denominated  in  foreign  currencies  are 
revalued  at  the  exchange  rate  in  effect  at  the  balance  sheet 
date  with  the  resulting  foreign  exchange  gains  and  losses 
included  in  net  income.  Accounts  that  are  classified  as  non-
monetary, such as deferred acquisition costs and the unearned 
premium  reserves,  are  not  revalued.  In  the  case  of  foreign 
currency  denominated  fixed  maturity  securities  which  are 
classified  as  “available  for  sale,”  the  change  in  exchange 
rates between the local currency in which the investments are 
denominated and the Company’s functional currency at each 
balance  sheet  date  is  included  in  unrealized  appreciation  or

decline  in  value  of  securities,  a  component  of  accumulated 
other  comprehensive  income,  net  of  applicable  deferred 
income tax.

(m) Income Taxes

Deferred  income  taxes  reflect  the  expected  future  tax 
consequences of temporary differences between the carrying 
amounts  of  assets  and  liabilities  for  financial  reporting 
purposes  and  amounts  used  for  income  tax  purposes.  A 
valuation  allowance  is  recorded  if  it  is  more  likely  than  not 
that  some  or  all  of  a  deferred  income  tax  asset  may  not  be 
realized.  The  Company  considers  future  taxable  income  and 
feasible  tax  planning  strategies  in  assessing  the  need  for  a 
valuation  allowance.  In  the  event  the  Company  determines 
that  it  will  not  be  able  to  realize  all  or  part  of  its  deferred 
income tax assets in the future, an adjustment to the deferred 
income tax assets would be charged to income in the period 
in  which  such  determination  is  made.  In  addition,  if  the 
Company subsequently assesses that the valuation allowance 
is no longer needed, a benefit would be recorded to income in 
the period in which such determination is made. See note 15, 
“Income Taxes” for additional information.

The  Company  recognizes  a  tax  benefit  where  it  concludes 
that  it  is  more  likely  than  not  that  the  tax  benefit  will  be 
sustained on audit by the taxing authority based solely on the 
technical  merits  of  the  associated  tax  position.  If  the 
recognition  threshold  is  met,  the  Company  recognizes  a  tax 
benefit measured at the largest amount of the tax benefit that, 
in the Company’s judgment, is greater than 50% likely to be 
realized. The Company records interest and penalties related 
to  unrecognized  tax  benefits  in  the  provision  for  income 
taxes.

On December 27, 2023 the Bermuda government enacted tax 
legislation referred to as the Corporate Income Tax Act 2023 
(“Bermuda  CIT  Act”).  The  Bermuda  CIT  Act  establishes  a 
15% corporate income tax, for in-scope businesses, for fiscal 
years  beginning  on  or  after  January  1,  2025.  The  enacted 
legislation  includes  a  provision  referred  to  as  the  Economic 
Transition  Adjustment,  which  requires  Bermuda  Constituent 
entities  to  establish  tax  basis  in  their  assets  and  liabilities, 
excluding goodwill, based on fair value as of September 30, 
2023.  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.  See  note  15,  “Income  Taxes”  for

The  Company  applies  a  fair  value  based  measurement 
method 
share-based  payment 
for 
arrangements  with  eligible  employees  and  directors. 
Compensation expense is estimated based on the fair value of 
the  award  at  the  grant  date  and  is  recognized  in  net  income 
over  the  requisite  service  period  with  a  corresponding 
increase  in  shareholders’  equity.  No  value  is  attributed  to 
awards  that  employees  forfeit  because  they  fail  to  satisfy 
vesting  conditions.  The  Company’s  (i)  time-based  awards 
generally vest over a three year period with one-third vesting 
on  the  first,  second  and  third  anniversaries  of  the  grant  date 
and (ii) performance-based awards cliff vest after each three 
year  performance  period  based  on  achievement  of  the 
specified 
share-based 
compensation  expense  associated  with  awards  that  have 
graded vesting features and vest based on service conditions 
only  is  calculated  on  a  straight-line  basis  over  the  requisite 
service  period  for  the  entire  award.  Compensation  expense 
recognized  in  connection  with  performance  awards  is  based 
on the achievement of the specified performance and service 
conditions.  The  final  measure  of  compensation  expense 
recognized over the requisite service period reflects the final 
performance  outcome.  During 
recognition  period 
compensation  expense  is  accrued  based  on  the  performance 
condition  that  is  probable  of  achievement.  For  awards 
granted to retirement-eligible employees where no service is 
required for the employee to retain the award, the grant date 
fair  value  is  immediately  recognized  as  compensation 
expense  at  the  grant  date  because  the  employee  is  able  to 
retain  the  award  without  continuing  to  provide  service.  For 
employees  near 
retirement  eligibility,  attribution  of 
compensation  cost  is  over  the  period  from  the  grant  date  to 
the  retirement  eligibility  date.  These  charges  had  no  impact 
on  the  Company’s  cash  flows  or  total  shareholders’  equity.

(q) Goodwill and Intangible Assets

(s) Funds Held Arrangements

Goodwill  represents  the  excess  of  the  purchase  price  of 
business  combination  over  the  fair  value  of  the  net  assets 
acquired  and  is  assigned  to  the  applicable  reporting  unit  at 
acquisition.  Goodwill  is  evaluated  for  impairment  on  an 
annual  basis.  Impairment  tests  may  be  performed  more 
frequently  if  the  facts  and  circumstances  indicate  a  possible 
impairment.  In  performing  impairment  tests,  the  Company 
may first assess qualitative factors to determine whether it is 
more  likely  than  not  (that  is,  more  than  a  50%  probability) 
that  the  fair  value  of  a  reporting  unit  exceeds  its  carrying 
amount as a basis for determining whether it is necessary to 
perform goodwill impairment test described in the accounting 
guidance. 

Indefinite-lived  intangible  assets,  such  as  insurance  licenses 
are evaluated for impairment similar to goodwill. Finite-lived 
intangible assets and liabilities include the value of acquired 
insurance  and  reinsurance  contracts,  which  are  estimated 
based on the present value of future expected cash flows and 
amortized  in  proportion  to  the  estimated  profits  expected  to 
be  realized.  Other  finite-lived  intangible  assets,  including 
customer  lists,  trade  name  and  IT  platforms,  are  amortized 
over  their  useful  lives.  Finite-lived  intangible  assets  and 
liabilities  are  periodically  reviewed  for 
indicators  of 
impairment. An impairment is recognized when the carrying 
amount  is  not  recoverable  from  its  undiscounted  cash  flows 
and  is  measured  as  the  difference  between  the  carrying 
amount and fair value.

If goodwill or intangible assets are impaired, such assets are 
written  down  to  their  fair  values  with  the  related  expense 
recorded in the Company’s results of operations.

(r) Investment in Operating Affiliates

Investment  in  operating  affiliates  primarily  represent  the 
Company’s investments in which it has significant influence 
and  which  are  accounted  for  under  the  equity  method  of 
accounting.  In  applying  the  equity  method  of  accounting, 
investments  in  operating  affiliates  are  initially  recorded  at 
cost  and  are  subsequently  adjusted  based  on  the  Company’s 
proportionate  share  of  net  income  or  loss  of  the  operating 
affiliate.  The  Company  records  its  proportionate  share  of 
other comprehensive income or loss of the operating affiliate 
as a component of other comprehensive income. Adjustments 
are based on the most recently available financial information 
from the operating affiliate. Changes in the carrying value of 
these  investments  are  recorded  in  income  (loss)  from 
operating affiliates.

Funds  held  arrangements  are  agreements  with  a  third  party 
reinsurance company, where the reinsured retains the related 
assets  on  a  funds  held  basis.  Such  amounts  are  included  in 
“Other  assets”  on  the  Company’s  balance  sheet.  Investment 
returns  produced  by  those  assets  are  recorded  as  part  of  net 
investment  income  and  net  realized  gains  (losses)  in  the 
Company's consolidated results of operations. Funds held as 
collateral by the Company are included in “Other liabilities” 
and changes to the funds held liability are reflected as part of 
interest  expense  in  the  Company’s  consolidated  results  of 
operations.

(t) Recent Accounting Pronouncements

Recently Issued Accounting Standards Not Yet Adopted

ASU 2020-04, “Facilitation of the Effects of Reference Rate 
Reform  on  Financial  Reporting,”  was  issued  in  March  2020 
and  amended  in  December  2022  with  ASU  2022-06, 
“Reference  Rate  Reform  (Topic  848)”.  This  ASU  provides 
optional  expedients  and  exceptions  for  applying  GAAP  to 
investments,  derivatives,  or  other  transactions  that  reference 
the  London  Interbank  Offered  Rate  (“LIBOR”)  or  another 
reference  rate  expected  to  be  discontinued  because  of 
reference rate reform. Along with the optional expedients, the 
amendments include a general principle that permits an entity 
to consider contract modifications due to reference reform to 
be an event that does not require contract re-measurement at 
the  modification  date  or  reassessment  of  a  previous 
accounting  determination.  The  amendment  deferred  the 
sunset date from December 31, 2022 to December 31, 2024. 
As  a  result,  this  standard  can  be  adopted  no  later  than 
December 31, 2024, with early adoption permitted. Based on 
its  current  analysis,  the  Company  does  not  expect  that  the 
new  guidance  will  have  a  material  effect  on  the  Company’s 
consolidated financial statements.

ASU  2023-07,  “Segment  Reporting  –  Improvements  to 
Reportable Segments Disclosures,” was issued in November 
2023. This ASU enhances disclosures of significant segment 
expenses  by  requiring 
to  disclose  significant  segment 
expenses  regularly  provided  to  the  chief  operating  decision 
maker  (“CODM”),  extend  certain  annual  disclosures  to 
interim  periods,  and  permit  more  than  one  measure  of 
segment profit or loss to be reported under certain conditions. 
The  amendments  are  effective  for  the  Company  in  fiscal 
years  beginning  after  December  15,  2023,  and  interim 
periods  within  fiscal  years  beginning  after  December  15, 
2024.  Early  adoption  of  the  amendment  is  permitted, 
including adoption in any interim periods for which financial 
statements  have  not  been  issued.  Based  on  its  current 
analysis, the Company does not expect that the new guidance 
will  have  a  material  effect  on  the  Company’s  consolidated 
financial statements.

Segment Information

The Company classifies its businesses into three underwriting 
segments  –  insurance,  reinsurance  and  mortgage  –  and  two 
operating  segments  –  corporate  and  ‘other.’  The  Company 
determined  its  reportable  segments  using  the  management 
approach  described 
regarding 
disclosures  about  segments  of  an  enterprise  and  related 
information. The accounting policies of the segments are the 
same  as  those  used  for  the  preparation  of  the  Company’s 
consolidated  financial  statements.  Intersegment  business  is 
allocated  to  the  segment  accountable  for  the  underwriting 
results.

in  accounting  guidance 

insurance, 

The  Company’s 
reinsurance  and  mortgage 
segments  each  have  managers  who  are  responsible  for  the 
overall profitability of their respective segments and who are 
directly  accountable  to  the  Company’s  chief  operating 
decision makers, the Chief Executive Officer of Arch Capital, 
Chief Financial Officer and Treasurer of Arch Capital and the 
President  and  Chief  Underwriting  Officer  of  Arch  Capital. 
The  chief  operating  decision  makers  do  not  assess 
performance,  measure  return  on  equity  or  make  resource 
allocation decisions on a line of business basis. Management 
measures  segment  performance  for  its  three  underwriting 
segments  based  on  underwriting  income  or  loss.  The 
Company  does  not  manage  its  assets  by  underwriting 
segment,  with  the  exception  of  goodwill  and  intangible 
assets,  and,  accordingly,  investment  income  is  not  allocated 
to each underwriting segment. 

The insurance segment consists of the Company’s insurance 
underwriting  units  which  offer  specialty  product  lines  on  a 
worldwide basis. Product lines include:

expense  from  a  single  occurrence  or  aggregation  of
losses  from  a  covered  peril  exceed  the  retention
specified in the contract.

Property  excluding  property  catastrophe:  provides
coverage for personal lines and/or commercial property

products on a worldwide basis. Underwriting units include:

• U.S.  primary  mortgage  insurance:  offers  private  mortgage
insurance  through  Arch  Mortgage  Insurance  Company  and
United Guaranty Residential Insurance Company (combined
“Arch MI U.S.”), both approved eligible mortgage insurers
by  Fannie  Mae  and  Freddie  Mac.  Arch  MI  U.S.  also

results of Somers. In July 2021, the Company announced the
completion of the previously disclosed acquisition of Somers
by  Greysbridge.  Based  on  the  governing  documents  of
Greysbridge,  the  Company  has  concluded  that,  while  it
retains  significant  influence  over  Somers,  Somers  no  longer
constitutes  a  variable  interest  entity.  Accordingly,  effective
July  1,  2021,  Arch  no  longer  consolidates  the  results  of
Somers in its consolidated financial statements. See note 12,
“Variable Interest Entity and Noncontrolling Interests.”

favorable 
development  of  $170  million,  or  13.2  points  of  net  earned 
premium.  Approximately  a  third  of  this  development  came 
from  the  U.S.  first  lien  portfolio,  which  benefited  from 
improving  economic  conditions  and  rising  home  prices, 
resulting 
in  reduced  claim  rate  assumptions  primarily 
associated with pre-pandemic delinquencies. Various vintage 
CRT  contracts  also  experienced  similar  effects  and 
contributed to the favorable development, including the effect 
of  contracts  called  by  the  GSEs.  Subrogation  recoveries  on 
second  lien  and  student  loan  business  and  international 
business also contributed to the favorable development.

Retroactive Reinsurance Transactions

In 2021, the Company entered into a retroactive reinsurance 
transaction  with  third  party  reinsurer  to  reinsure  run-off 
liabilities associated with certain U.S. insurance exposures. 

In  2021,  the  Company  entered  into  a  reinsurance  to  close 
with the related party, in connection with the 2018 and prior 
years  of  account  for  certain  London  syndicate  business.  See 
note 16, “Transactions with Related Parties”.

The  Company’s  reserves  for  losses  and  loss  adjustment 
expenses  primarily  relate  to  short-duration  contracts  with 
various  characteristics  (e.g.,  type  of  coverage,  geography, 
claims duration). The Company considered such information

reinsurance 

The Company is required to establish reserves for losses and 
loss  adjustment  expenses  (“Loss  Reserves”)  that  arise  from 
the business the Company underwrites. Loss Reserves for the 
insurance,  reinsurance  and  mortgage  segments  represent 
estimates  of  future  amounts  required  to  pay  losses  and  loss 
adjustment  expenses  for  insured  or  reinsured  events  which 
have  occurred  at  or  before  the  balance  sheet  date.  Loss 
Reserves  do  not  reflect  contingency  reserve  allowances  to 
account  for  future  loss  occurrences.  Losses  arising  from 
future events will be estimated and recognized at the time the 
losses are incurred and could be substantial.

Insurance Segment

Loss  Reserves  for  the  insurance  segment  are  comprised  of 
estimated  amounts  for  (1)  reported  losses  (“case  reserves”) 
and  (2)  incurred  but  not  reported  losses  (“IBNR  reserves”). 
Generally, claims personnel determine whether to establish a 
case  reserve  for  the  estimated  amount  of  the  ultimate 
settlement  of  individual  claims.  The  estimate  reflects  the 
judgment  of  claims  personnel  based  on  general  corporate 
reserving  practices,  the  experience  and  knowledge  of  such 
personnel regarding the nature and value of the specific type 
of  claim  and,  where  appropriate,  advice  of  counsel.  The 
Company also contracts with a number of outside third party 
administrators  in  the  claims  process  who,  in  certain  cases, 
have limited authority to establish case reserves. The work of 
such administrators is reviewed and monitored by our claims 
personnel.  Loss  Reserves  are  also  established  to  provide  for 
loss adjustment expenses and represent the estimated expense 
of  settling  claims,  including  legal  and  other  fees  and  the 
general  expenses  of  administering  the  claims  adjustment 
process. Periodically, adjustments to the case reserves may be 
made  as  additional  information  is  reported  or  payments  are 
made. IBNR reserves are established to provide for incurred 
claims which have not yet been reported at the balance sheet 
date  as  well  as  to  adjust  for  any  projected  variance  in  case 
reserving.  Actuaries  estimate  ultimate 
loss 
adjustment  expenses  using  various  generally  accepted 
actuarial methods applied to known losses and other relevant 
information.  Like  case  reserves,  IBNR  reserves  are  adjusted 
as  additional  information  becomes  known  or  payments  are 
made.  The  process  of  estimating  reserves 
involves  a 
considerable  degree  of  judgment  by  management  and,  as  of 
any given date, is inherently uncertain.

in  estimating  ultimate 

Ultimate  losses  and  loss  adjustment  expenses  are  generally 
determined by projection of claim emergence and settlement 
patterns observed in the past that can reasonably be expected 
to  persist  into  the  future.  In  forecasting  ultimate  losses  and 
loss adjustment expenses with respect to any line of business, 
past  experience  with  respect  to  that  line  of  business  is  the 
primary  resource,  developed  through  both  industry  and 
company  experience,  but  cannot  be  relied  upon  in  isolation. 
Uncertainties 
loss 
adjustment expenses are magnified by the length of the time 
lag  between  when  a  claim  actually  occurs  and  when  it  is 
reported and settled. This time lag is sometimes referred to as 
the “claim-tail.” During this period additional facts regarding 
coverages  written  in  prior  accident  years,  as  well  as  about 
actual claims and trends, may become known and, as a result, 
may lead to adjustments of the related Loss Reserves. If the 
Company  determines  that  an  adjustment  is  appropriate,  the 
adjustment  is  recorded  in  the  accounting  period  in  which 
such  determination  is  made.  Accordingly,  should  Loss 
Reserves need to be increased or decreased in the future from 
amounts  currently  established,  future  results  of  operations 
would be negatively or positively impacted respectively. The 

Company authorizes managing general agents, general agents 
and  other  producers  to  write  program  business  on  the 
Company’s behalf within prescribed underwriting authorities. 
This  delegated  authority  process 
introduces  additional 
complexity  to  the  actuarial  determination  of  unpaid  future 
losses  and  loss  adjustment  expenses.  In  order  to  monitor 
adherence  to  the  underwriting  guidelines  given  to  such 
parties, the Company periodically performs underwriting and 
claims due diligence reviews.

In determining ultimate losses and loss adjustment expenses, 
the cost to indemnify claimants, provide needed legal defense 
and  other  services 
the 
investigation and adjustment of claims are considered. These 
claim costs are influenced by many factors that change over 
time,  such  as  expanded  coverage  definitions  as  a  result  of 
new  court  decisions,  inflation  in  costs  to  repair  or  replace 
damaged  property,  inflation  in  the  cost  of  medical  services 
and legislated changes in statutory benefits, as well as by the 
particular, unique facts that pertain to each claim. As a result, 
the  rate  at  which  claims  arose  in  the  past  and  the  costs  to 
settle  them  may  not  always  be  representative  of  what  will 
occur in the future. The factors influencing changes in claim 
costs  are  often  difficult 
isolate  or  quantify  and 
to 
developments  in  paid  and  incurred  losses  from  historical 
trends  are  frequently  subject  to  multiple  and  conflicting 
interpretations. Changes in coverage terms or claims handling 
practices  may  also  cause 
future  experience  and/or 
development patterns to vary from the past. A key objective 
of  actuaries  in  developing  estimates  of  ultimate  losses  and 
loss adjustment expenses, and resulting IBNR reserves, is to 
identify  aberrations  and  systemic  changes  occurring  within 
historical  experience  and  adjust  for  them  so  that  the  future 
can  be  projected  more  reliably.  Because  of  the  factors 
previously discussed, this process requires the substantial use 
of informed judgment and is inherently uncertain.

Although  Loss  Reserves  are  initially  determined  based  on 
underwriting and pricing analyses, the Company’s insurance 
segment  applies  several  generally  accepted  actuarial 
methods, as discussed below, on a quarterly basis to evaluate 
the Loss Reserves, in addition to the expected loss method, in 
particular for Loss Reserves from more mature accident years 
(the  year  in  which  a  loss  occurred).  Each  quarter,  as  part  of 
the  reserving  process,  the  segments’  actuaries  reaffirm  that 
the  assumptions  used  in  the  reserving  process  continue  to 
form  a  sound  basis  for  the  projection  of  liabilities.  If  actual 
loss activity differs substantially from expectations based on 
historical  information,  an  adjustment  to  Loss  Reserves  may 
be supported. The Company places more or less reliance on a 
particular  actuarial  method  based  on 
facts  and 
circumstances at the time the estimates of Loss Reserves are 
made.

typically  developed  based  upon 

Expected loss methods - these methods are based on the
assumption that ultimate losses vary proportionately with
premiums.  Expected  loss  and  loss  adjustment  expense
ratios  are 
the
information derived by underwriters and actuaries during
the  initial  pricing  of  the  business,  supplemented  by
industry  data  available  from  organizations,  such  as
statistical  bureaus  and  consulting 
firms,  where
appropriate.  These  ratios  consider,  among  other  things,
rate  increases  and  changes  in  terms  and  conditions  that
have  been  observed  in  the  market.  Expected  loss
methods  are  useful  for  estimating  ultimate  losses  and
loss adjustment expenses in the early years of long-tailed
lines of business, when little or no paid or incurred loss
information is available, and is commonly applied when
limited loss experience exists for a company.

Historical  incurred  loss  development  methods  -  these
methods assume that the ratio of losses in one period to
losses  in  an  earlier  period  will  remain  constant  in  the
future. These methods use incurred losses (i.e., the sum
of  cumulative  historical  loss  payments  plus  outstanding
case  reserves)  over  discrete  periods  of  time  to  estimate
future  losses.  Historical  incurred  loss  development
methods  may  be  preferable  to  historical  paid  loss
development  methods  because  they  explicitly  take  into
account open cases and the claims adjusters’ evaluations
of  the  cost  to  settle  all  known  claims.  However,
historical incurred loss development methods necessarily
assume  that  case  reserving  practices  are  consistently
applied  over  time.  Therefore,  when  there  have  been
significant changes in how case reserves are established,
using incurred loss data to project ultimate losses may be
less reliable than other methods.

incurred 

like  historical 

Historical  paid  loss  development  methods  -  these
methods, 
loss  development
methods, assume that the ratio of losses in one period to
losses  in  an  earlier  period  will  remain  constant.  These
methods  use  historical  loss  payments  over  discrete
periods of time to estimate future losses and necessarily
assume that factors that have affected paid losses in the
past,  such  as  inflation  or  the  effects  of  litigation,  will
remain  constant  in  the  future.  Because  historical  paid
loss development methods do not use incurred losses to
estimate ultimate losses, they may be more reliable than
the  other  methods  that  use  incurred  losses  in  situations
where  there  are  significant  changes  in  how  incurred
losses  are  established  by  a  company’s  claims  adjusters.
However,  historical  paid  loss  development  methods  are
more leveraged (meaning that small changes in payments
have a larger impact on estimates of ultimate losses) than

actuarial  methods  that  use  incurred  losses  because 
cumulative loss payments take much longer to equal the 
expected  ultimate 
incurred 
amounts.  In  addition,  and  for  similar  reasons,  historical 
paid loss development methods are often slow to react to 
situations when new or different factors arise than those 
that have affected paid losses in the past.

Adjusted  historical  paid  and  incurred  loss  development
methods  -  these  methods  take  traditional  historical  paid
and incurred loss development methods and adjust them
for  the  estimated  impact  of  changes  from  the  past  in
factors such as inflation, the speed of claim payments or
the  adequacy  of  case  reserves.  Adjusted  historical  paid
and  incurred  loss  development  methods  are  often  more
reliable methods of predicting ultimate losses in periods
of significant change, provided the actuaries can develop
methods  to  reasonably  quantify  the  impact  of  changes.
As  such,  these  methods  utilize  more  judgment  than
historical paid and incurred loss development methods.

Bornhuetter-Ferguson  (“B-F”)  paid  and  incurred  loss
methods - these methods utilize actual paid and incurred
losses and expected patterns of paid and incurred losses,
taking the initial expected ultimate losses into account to
determine  an  estimate  of  expected  ultimate  losses.  The
B-F  paid  and  incurred  loss  methods  are  useful  when
there are few reported claims and a relatively less stable
pattern of reported losses.

Frequency-Severity  methods  -  These  methods  utilize
actual paid and incurred claim experience, but break the
data down into its component pieces: claim counts, often
expressed as a ratio to exposure or premium (frequency),
and average claim size (severity). The component pieces
are projected to an ultimate level and multiplied together
to  result  in  an  estimate  of  ultimate  loss.  These  methods
are especially useful when the severity of claims can be
confined  to  a  relatively  stable  range  of  estimated
ultimate average claim value.

Additional analyses - other methodologies are often used
in  the  reserving  process  for  specific  types  of  claims  or
events,  such  as  catastrophic  or  other  specific  major
events. These include vendor catastrophe models, which
are  typically  used  in  the  estimation  of  Loss  Reserves  at
the  early  stage  of  known  catastrophic  events  before
information has been reported to an insurer or reinsurer.

In  the  initial  reserving  process  for  short-tail  insurance  lines 
(consisting  of  property,  energy,  marine  and  aviation  and 
other  exposures  including  travel,  accident  and  health,  and 
warranty  and  lenders  solutions),  the  Company  relies  on  a 
combination  of  the  reserving  methods  discussed  above.  For 
catastrophe-exposed  business,  the  reserving  process  also 
includes  the  usage  of  catastrophe  models  for  known  events

that  historical  paid  and 

and  a  heavy  reliance  on  analysis  of  individual  catastrophic 
events  and  management  judgment.  The  development  of 
losses  on  short-tail  business  can  be  unstable,  especially  for 
policies characterized by high severity, low frequency losses. 
As time passes, for a given accident year, additional weight is 
given to the paid and incurred B-F loss development methods 
and  eventually  to  the  historical  paid  and  incurred  loss 
development methods in the reserving process. The Company 
makes  a  number  of  key  assumptions  in  their  reserving 
reported 
process, 
development  patterns  are  stable,  catastrophe  models  provide 
useful information about our exposure to catastrophic events 
that have occurred and underwriters’ judgment as to potential 
loss exposures can be relied on. The expected loss ratios used 
in  the  initial  reserving  process  for  short-tail  business  have 
varied  over  time  due  to  changes  in  pricing,  reinsurance 
structure,  estimates  of  catastrophe  losses,  policy  changes 
(such as attachment points, class and limits) and geographical 
distribution.  As  losses  in  short-tail  lines  are  reported 
relatively  quickly,  expected  loss  ratios  are  selected  for  the 
current accident year based upon actual attritional loss ratios 
for earlier accident years, adjusted for rate changes, inflation, 
changes  in  reinsurance  programs  and  expected  attritional 
losses  based  on  modeling.  Furthermore,  ultimate  losses  for 
short-tail business are known in a reasonably short period of 
time.

In the initial reserving process for medium-tail and long-tail 
insurance lines (consisting of third party occurrence business, 
third  party  claims  made  business,  and  other  exposures 
including  surety,  programs  and  contract  binding  exposures), 
the  Company  primarily  relies  on  the  expected  loss  method. 
The  development  of  the  Company’s  medium-tail  and  long-
tail  business  may  be  unstable,  especially  if  there  are  high 
severity major events, as a portion of the Company’s casualty 
business is in high excess layers. As time passes, for a given 
accident  year,  additional  weight  is  given  to  the  paid  and 
incurred  B-F  loss  development  methods  and  historical  paid 
and  incurred  loss  development  methods  in  the  reserving 
process. The Company makes a number of key assumptions 

industry 

in  reserving  for  medium-tail  and  long-tail  lines,  including 
that the pricing loss ratio is the best estimate of the ultimate 
loss  ratio  at  the  time  the  policy  is  entered  into,  that  the  loss 
development  patterns,  which  are  based  on  a  combination  of 
company  and 
loss  development  patterns  and 
adjusted to reflect differences in the insurance segment’s mix 
of  business,  are  reasonable  and  that  claims  personnel  and 
underwriters  analyses  of  our  exposure  to  major  events  are 
assumed  to  be  the  best  estimate  of  exposure  to  the  known 
claims  on  those  events.  The  expected  loss  ratios  used  in  the 
initial  reserving  process  for  medium-tail  and  long-tail 
business  for  recent  accident  years  have  varied  over  time,  in 
some cases significantly, from earlier accident years. As the 
credibility  of  historical  experience  for  earlier  accident  years 
increases,  the  experience  from  these  accident  years  will  be 
given  a  greater  weighting  in  the  actuarial  analysis  to 
determine future accident year expected loss ratios, adjusted 
for changes in pricing, loss trends, terms and conditions and 
reinsurance structure. 

From  time  to  time,  the  Company  enters  into  loss  portfolio 
transfer  and  adverse  development  cover 
reinsurance 
agreements  accounted  for  as  retroactive  reinsurance.  These 
agreements  transfer  Loss  Reserves  and  future  favorable  or 
adverse development on certain runoff programs and certain 
third  party  occurrence  business,  within  multi-line  and  other 
specialty business (the “Covered Lines”). As incurred losses 
and allocated loss adjustment expenses for the Covered Lines 
are  ceded  to  the  reinsurer,  the  Company  is  not  exposed  to 
changes in the amount, timing and uncertainty of cash flows 
arising  from  the  Covered  Lines.  To  avoid  distortion,  the 
incurred  losses  and  allocated  loss  adjustment  expenses  and 
cumulative  paid  losses  and  loss  adjustment  expenses  for  the 
Covered  Lines  are  excluded  entirely  from  the  tables  below.

reinsurance agreements.

Reinsurance Segment

the  amount  of 

reserves  based  upon 

Loss  Reserves  for  the  Company’s  reinsurance  segment  are 
comprised  of  (1)  case  reserves,  (2)  additional  case  reserves 
(“ACRs”)  and  (3)  IBNR  reserves.  The  Company  receives 
reports of claims notices from ceding companies and records 
case 
reserves 
recommended by the ceding company. Case reserves may be 
supplemented  by  ACRs,  which  may  be  estimated  by  the 
Company’s  claims  personnel  ahead  of  official  notification 
from  the  ceding  company,  or  when  judgment  regarding  the 
size  or  severity  of  the  known  event  differs  from  the  ceding 
company.  In  certain  instances,  the  Company  establishes 
ACRs  even  when  the  ceding  company  does  not  report  any 
liability  on  a  known  event.  In  addition,  specific  claim 
information  reported  by  ceding  companies  or  obtained 
through  claim  audits  can  alert  the  Company  to  emerging 
trends such as changing legal interpretations of coverage and 
liability,  claims  from  unexpected  sources  or  classes  of 
business, and significant changes in the frequency or severity 
of  individual  claims.  Such  information  is  often  used  in  the 
process  of  estimating  IBNR  reserves.  IBNR  reserves  are 
established to provide for incurred claims which have not yet 
been reported at the balance sheet date as well as to adjust for 
any  projected  variance  in  case  reserving.  Actuaries  estimate 
ultimate  losses  and  loss  adjustment  expenses  using  various 
generally accepted actuarial methods applied to known losses 
and  other  relevant  information.  Like  case  reserves,  IBNR 
reserves  are  adjusted  as  additional  information  becomes 
known or payments are made. The process of estimating Loss 
Reserves  involves  a  considerable  degree  of  judgment  by 
management  and,  as  of  any  given  date,  is  inherently 
uncertain.

The estimation of Loss Reserves for the reinsurance segment 
is  subject  to  the  same  risk  factors  as  the  estimation  of  Loss 
Reserves for the insurance segment. In addition, the inherent 
uncertainties of estimating such reserves are even greater for 
reinsurers,  due  primarily  to  the  following  factors:  (1)  the 
claim-tail  for  reinsurers  is  generally  longer  because  claims 
are  first  reported  to  the  ceding  company  and  then  to  the 
reinsurer through one or more intermediaries, (2) the reliance 
on premium estimates, where reports have not been received 
from  the  ceding  company,  in  the  reserving  process,  (3)  the 
potential  for  writing  a  number  of  reinsurance  contracts  with 
different  ceding  companies  with  the  same  exposure  to  a 
single  loss  event,  (4)  the  diversity  of  loss  development 

patterns  among  different  types  of  reinsurance  contracts,  (5) 
the  ceding  companies  for 
the  necessary  reliance  on 
information  regarding  reported  claims  and  (6)  the  differing 
reserving practices among ceding companies.

Ultimate  losses  and  loss  adjustment  expenses  are  generally 
determined by projection of claim emergence and settlement 
patterns observed in the past that can reasonably be expected 
to persist into the future. As with the insurance segment, the 
process  of  estimating  Loss  Reserves  for  the  reinsurance 
segment  involves  a  considerable  degree  of  judgment  by 
management  and,  as  of  any  given  date,  is  inherently 
uncertain. As discussed above, such uncertainty is greater for 
reinsurers compared to insurers. As a result, our reinsurance 
operations  obtain  information  from  numerous  sources  to 
assist  in  the  process.  Pricing  actuaries  from  the  reinsurance 
segment  devote  considerable  effort  to  understanding  and 
analyzing  a  ceding  company’s  operations  and  loss  history 
during the underwriting of the business, using a combination 
of  ceding  company  and  industry  statistics.  Such  statistics 
normally include historical premium and loss data by class of 
business,  individual  claim  information  for  larger  claims, 
distributions of insurance limits provided, loss reporting and 
payment  patterns,  and  rate  change  history.  This  analysis  is 
used to project expected loss ratios for each treaty during the 
upcoming contract period.

As  mentioned  above,  there  can  be  a  considerable  time  lag 
from the time a claim is reported to a ceding company to the 
time  it  is  reported  to  the  reinsurer.  The  lag  can  be  several 
years  in  some  cases  and  may  be  attributed  to  a  number  of 
reasons,  including  the  time  it  takes  to  investigate  a  claim, 
delays associated with the litigation process, the deterioration 
in  a  claimant’s  physical  condition  many  years  after  an 
accident  occurs,  the  case  reserving  approach  of  the  ceding 
company,  etc.  In  the  reserving  process,  the  Company 
assumes that such lags are predictable, on average, over time 
and therefore the lags are contemplated in the loss reporting 
patterns used in their actuarial methods. This means that the 
reinsurance  segment  must  rely  on  estimates  for  a  longer 
period of time than does an insurance company. Backlogs in 
the recording of assumed reinsurance can also complicate the 
accuracy  of  loss  reserve  estimation.  As  of  December  31, 
2023  there  were  no  significant  backlogs  related  to  the 
processing  of  assumed  reinsurance  information  at  our 
reinsurance operations.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The  reinsurance  segment  relies  heavily  on  information 
reported  by  ceding  companies,  as  discussed  above.  In  order 
to  determine 
the  accuracy  and  completeness  of  such 
information,  underwriters,  actuaries,  and  claims  personnel 
often  perform  audits  of  ceding  companies  and  regularly 
review  information  received  from  ceding  companies  for 
unusual  or  unexpected  results.  Material  findings  are  usually 
discussed  with 
the  ceding  companies.  The  Company 
sometimes encounters situations where they determine that a 
claim  presentation  from  a  ceding  company  is  not  in 
accordance  with  contract  terms.  In  these  situations,  the 
Company  attempts  to  resolve  the  dispute  with  the  ceding 
company. Most situations are resolved amicably and without 
the  need  for  litigation  or  arbitration.  However,  in  the 
infrequent  situations  where  a  resolution  is  not  possible,  the 
Company will vigorously defend its position in such disputes.

Although  Loss  Reserves  are  initially  determined  based  on 
underwriting  and  pricing  analysis,  the  Company  applies 
several  generally  accepted  actuarial  methods,  as  discussed 
above,  on  a  quarterly  basis  to  evaluate  its  Loss  Reserves  in 
addition  to  the  expected  loss  method,  in  particular  for 
reserves  from  more  mature  underwriting  years  (the  year  in 
which business is underwritten). Each quarter, as part of the 
reserving process, the Company’s actuaries reaffirm that the 
assumptions used in the reserving process continue to form a 
sound basis for projection of liabilities. If actual loss activity 
differs  substantially  from  expectations  based  on  historical 
information,  an  adjustment  to  Loss  Reserves  may  be 
supported.  Estimated  Loss  Reserves  for  more  mature 
underwriting years are now based more on actual loss activity 
and  historical  patterns  than  on  the  initial  assumptions  based 
on  pricing  indications.  More  recent  underwriting  years  rely 
more heavily on internal pricing assumptions. The Company 
places more or less reliance on a particular actuarial method 
based on the facts and circumstances at the time the estimates 
of Loss Reserves are made.

In the initial reserving process for short-tail reinsurance lines 
(consisting  of  property  excluding  property  catastrophe  and 
property  catastrophe  exposures),  the  Company  relies  on  a 
combination  of  the  reserving  methods  discussed  above.  For 
known  catastrophic  events, 
the  reserving  process  also 
includes  the  usage  of  catastrophe  models  and  a  heavy 
reliance on analysis which includes ceding company inquiries 
and  management  judgment.  The  development  of  property 
losses  may  be  unstable,  especially  where  there  is  high 
catastrophic exposure, may be characterized by high severity, 
low  frequency  losses  for  excess  and  catastrophe-exposed 
business  and  may  be  highly  correlated  across  contracts.  As 
time passes, for a given underwriting year, additional weight 
is  given  to  the  paid  and  incurred  B-F  loss  development 
methods  and  historical  paid  and  incurred  loss  development 

to  potential 

methods  in  the  reserving  process.  The  Company  makes  a 
number  of  key  assumptions  in  reserving  for  short-tail  lines, 
including  that  historical  paid  and  reported  development 
patterns  are  stable,  catastrophe  models  provide  useful 
information  about  our  exposure  to  catastrophic  events  that 
have occurred and our underwriters’ judgment and guidance 
received  from  ceding  companies  as 
loss 
exposures may be relied on. The expected loss ratios used in 
the  initial  reserving  process  for  property  exposures  have 
varied  over  time  due  to  changes  in  pricing,  reinsurance 
terms  and 
structure,  estimates  of  catastrophe 
conditions  and  geographical  distribution.  As 
in 
losses 
property  lines  are  reported  relatively  quickly,  expected  loss 
ratios  are  selected  for 
the  current  underwriting  year 
incorporating  the  experience  for  earlier  underwriting  years, 
adjusted  for  rate  changes,  inflation,  changes  in  reinsurance 
programs,  expectations  about  present  and  future  market 
conditions and expected attritional losses based on modeling. 
Due  to  the  short-tail  nature  of  property  business,  reported 
loss  experience  emerges  quickly  and  ultimate  losses  are 
known in a reasonably short period of time.

assumptions in reserving for medium-tail and long-tail lines, 
including that the pricing loss ratio is the best estimate of the 
ultimate  loss  ratio  at  the  time  the  contract  is  entered  into, 
historical  paid  and  reported  development  patterns  are  stable 
and  claims  personnel  and  underwriters’  analyses  of  our 
exposure  to  major  events  are  our  best  estimate  of  our 
exposure to the known claims on those events. The expected 
loss  ratios  used  in  our  reinsurance  operations’  initial 
reserving  process  for  medium-tail  and  long-tail  contracts 
have  varied  over  time  due  to  changes  in  pricing,  terms  and 
conditions  and  reinsurance  structure.  As  the  credibility  of 
historical experience for earlier underwriting years increases, 
the  experience  from  these  underwriting  years  is  used  in  the 
actuarial  analysis  to  determine  future  underwriting  year 
expected  loss  ratios,  adjusted  for  changes  in  pricing,  loss 
trends, terms and conditions and reinsurance structure.

The Company’s mortgage segment includes (1) U.S. primary 
mortgage  insurance  (2)  U.S.  credit  risk  transfer  and  other, 
and  (3)  international  mortgage  insurance  and  reinsurance. 
The latter two categories along with second lien and student 
loan exposures are excluded on the basis of insignificance for 
the  purposes  of  presenting  disclosures  related  to  short 
duration contracts.

For  primary  mortgage  insurance  business,  the  Company 
establishes case reserves for loans that have been reported as 
delinquent  by  loan  servicers  as  well  as  those  that  are 
delinquent  but  not  reported  (IBNR  reserves).  The  Company 
also  reserves  for  the  expenses  of  adjusting  claims  related  to 
these  delinquencies.  The  trigger  that  creates  a  case  reserve 
estimate is that an insured loan is reported to us as being two 
and 
payments 

arrears.  The 

actuarial 

reviews 

in 

documentation created in the reserving process are completed 
in  accordance  with  generally  accepted  actuarial  standards. 
The selected assumptions reflect actuarial judgment based on 
the analysis of historical data and experience combined with 
information  concerning  current  underwriting,  economic, 
judicial,  regulatory  and  other  influences  on  ultimate  claim 
settlements.

Because  the  reserving  process  requires  the  Company  to 
forecast  future  conditions,  it  is  inherently  uncertain  and 
requires  significant  judgment  and  estimation.  The  use  of 
different  estimates  would  result  in  the  establishment  of 
different  reserve  levels.  Additionally,  changes  in  estimates 
are  likely  to  occur  from  period  to  period  as  economic 
conditions  change,  and  the  ultimate  liability  may  vary 
significantly  from  the  estimates  used.  Major  risk  factors 
include  (but  are  not  limited  to)  changes  in  home  prices  and 
borrower equity, which can limit the borrower’s ability to sell

the  property  and  satisfy  the  outstanding  loan  balance,  and 
changes  in  unemployment,  which  can  affect  the  borrower’s 
income and ability to make mortgage payments. The unique 
nature  of  the  COVID-19  pandemic,  with  no  historical 
precedent,  adds  further  uncertainty 
to  current  reserve 
estimates.

The  lead  actuarial  methodology  used  by  the  Company  is  a 
frequency-severity method based on the inventory of pending 
delinquencies.  Each  month  the  loan  servicers  report  the 
delinquency status of each insured loan. Using the frequency-
severity method allows the Company to take advantage of its 
knowledge  of  the  number  of  delinquent  loans  and  the 
coverage  provided  (“risk  size”)  on  those  loans  by  directly 
relating the reserves to these amounts. The delinquencies are 
grouped  into  homogeneous  cohorts  for  analysis,  reflecting 
the  age  of  delinquency.  A  claim  rate  is  then  developed  for 
each  cohort  which  represents  the  frequency  with  which  the 
delinquencies become claims. The claim frequency rates are 
based on an analysis of the patterns of emerging cure counts 
and  claim  counts,  the  foreclosure  status  of  the  pending 
delinquencies,  the  product  and  geographical  mix  of  the 
delinquencies  and  our  view  of  future  economic  and  claim 
conditions,  which 
in  home  prices  and 
unemployment.  Claim  rates  can  vary  materially  by  age  of 
delinquency,  depending  on  the  mix  of  delinquencies  and 
economic conditions.

include 

trends 

Claim  size  severity  estimates  are  determined  by  examining 
the  risk  sizes  on  the  delinquent  loans  and  estimating  the 
portion of risk that will be paid, as well as any expenses. This 
is done based on a review of historical development patterns, 
an assessment of economic conditions and the level of equity 
the  borrowers  may  have  in  their  homes,  as  well  as 
considering  economic  conditions  and 
loss  mitigation 
opportunities. Mortgage insurance is generally not subject to 
large  claim  sizes,  as  with  some  other  lines  of  insurance.  A 

claim  size  over  $250,000  is  rare,  and  this  helps  reduce  the 
volatility of claim size estimates.

The  claim  rate  and  claim  size  assumptions  generate  case 
reserves  for  the  population  of  reported  delinquencies.  The 
reserve  for  unreported  delinquencies  (included  in  IBNR 
reserves)  is  estimated  by  looking  at  historical  patterns  of 
reporting. Claim rates and claim sizes can then be assigned to 
estimated  unreported  delinquencies  using  assumptions  made 
in the establishment of case reserves.

Mortgage insurance Loss Reserves are short-tail, in the sense 
that  the  vast  majority  of  delinquencies  are  resolved  within 
two  years  of  being  reported.  Due  to  the  forbearances  and 
foreclosure  moratoriums  associated  with  COVID-19, 
settlement timelines have been extended. While reserves are 
initially analyzed by reserve cohort, as described above, they 
are also rolled up by underwriting year to ensure that reserve 
assumptions  are  consistent  with  the  performance  of  the 
underwriting year. The accuracy of prior reserve assumptions 
is also checked in hindsight to determine if adjustments to the 
assumptions are needed.

Loss  Reserves  for  the  Company’s  mortgage  reinsurance 
business  and  GSE  credit  risk  sharing  transactions  are 
comprised  of  case  reserves  and  IBNR  reserves.  The 
Company’s  mortgage  reinsurance  operations  receive  reports 
loans  and  claims  notices  from  ceding 
of  delinquent 
companies  and  record  case  reserves  based  upon  the  amount 
of  reserves  recommended  by  the  ceding  company.  In 
addition, specific claim and delinquency information reported 
by  ceding  companies  is  used  in  the  process  of  estimating 
IBNR reserves.

In  the  normal  course  of  business,  the  Company’s  insurance 
subsidiaries cede a portion of their premium through pro rata 
and  excess  of  loss  reinsurance  agreements  on  a  treaty  or 
facultative basis to third parties. The Company’s reinsurance 
subsidiaries  participate  in  “common  account”  retrocessional 
arrangements for certain pro rata treaties. Such arrangements 
reduce  the  effect  of  individual  or  aggregate  losses  to  all 
companies  participating  on  such  treaties,  including  the 
reinsurers,  such  as  the  Company’s  reinsurance  subsidiaries, 
and  the  ceding  company.  In  addition,  the  Company’s 
retrocessional 
subsidiaries  may  purchase 
reinsurance 
coverage  as  part  of  their  risk  management  program.  The 
Company’s  mortgage  subsidiaries  cede  a  portion  of  their 
premium  through  quota  share  arrangements  and  enter  into 
various  aggregate  excess  of  loss  mortgage  reinsurance 
reinsurance 
agreements  with  various  special  purpose 
companies.  Reinsurance  recoverables  are  recorded  as  assets, 
predicated on the reinsurers’ ability to meet their obligations 
under the reinsurance agreements. If the reinsurers are unable 
to  satisfy  their  obligations  under  the  agreements,  the 
Company’s  insurance  or  reinsurance  subsidiaries  would  be 
liable for such defaulted amounts.

The  effects  of  reinsurance  on  the  Company’s  written  and

The  Company  has  entered  into  various  aggregate  excess  of 
loss  mortgage  reinsurance  agreements  with  various  special 
purpose  reinsurance  companies  domiciled  in  Bermuda  (the 
“Bellemeade  Agreements”).  For  the  respective  coverage 
periods,  the  Company  will  retain  the  first  layer  of  the 
respective  aggregate 
the  special  purpose 
losses  and 
reinsurance companies will provide second layer coverage up 
to the outstanding coverage amount. The Company will then 
retain losses in excess of the outstanding coverage limit. The 
aggregate excess of loss reinsurance coverage decreases over 
a  ten-year  period  as  the  underlying  covered  mortgages 
amortize.  See  note  12,  “Variable  Interest  Entity  and

Company’s  proportionate  share  of  the  net  income  or  loss  of 
the  funds  (which  include  changes  in  the  fair  value  of  the

Certain of the Company’s other investments and investments 
accounted  for  using  the  equity  method  are  in  investment 
funds  for  which  the  Company  has  the  option  to  redeem  at 
agreed  upon  values  as  described  in  each  investment  fund’s 
subscription  agreement.  Depending  on  the  terms  of  the 
various  subscription  agreements,  investments  in  investment 
funds may be redeemed daily, monthly, quarterly or on other 
terms.  Two  common  redemption  restrictions  which  may 
impact  the  Company’s  ability  to  redeem  these  investment 
funds  are  gates  and  lockups.  A  gate  is  a  suspension  of 
redemptions  which  may  be  implemented  by  the  general 
partner or investment manager of the fund in order to defer, 
in  whole  or  in  part,  the  redemption  request  in  the  event  the 
requests  exceeds  a 
redemption 
aggregate  amount  of 
predetermined percentage of the investment fund's net assets 
which  may  otherwise  hinder 
the  general  partner  or 
investment  manager's  ability  to  liquidate  holdings  in  an 
orderly  fashion  in  order  to  generate  the  cash  necessary  to 
fund  extraordinarily  large  redemption  payouts.  A  lockup 
period 
is 
contractually required to hold the security before having the 
ability  to  redeem.  If  the  investment  funds  are  eligible  to  be 
redeemed,  the  time  to  redeem  such  fund  can  take  weeks  or 
months following the notification.

Limited Partnership Interests

In the normal course of its activities, the Company invests in 
limited partnerships as part of its overall investment strategy. 
Such  amounts  are  included  in  ‘investments  accounted  for 
using  the  equity  method’  and  ‘investments  accounted  for 
using  the  fair  value  option.’  The  Company  determined  that 
these 
interests  represented  variable 
interests in the funds. The Company’s maximum exposure to 

limited  partnership 

loss  with  respect  to  these  investments  is  limited  to  the 
investment  carrying  amounts  reported  in  the  Company’s 
consolidated balance sheet and any unfunded commitment.

Investments in Operating Affiliates

Investments in which the Company has significant influence 
over  the  operating  and  financial  policies  are  classified  as 
‘investments  in  operating  affiliates’  on  the  Company’s 
balance  sheets  and  are  accounted  for  under  the  equity 
method.  Such  investments  primarily  include  the  Company’s 
investment  in  Coface  SA  (“Coface”),  Greysbridge  and 
Premia.  Investments  in  Coface  and  Premia  are  generally 
recorded  on  a  three  month  lag,  while  the  Company’s 
investment in Greysbridge is not recorded on a lag.

In  2021,  the  Company  completed  the  share  purchase 
agreement  with  Natixis  to  purchase  29.5%  of  the  common 
equity  of  Coface,  a  France-based  leader  in  the  global  trade 
credit  insurance  market.  The  consideration  paid  was  €9.95 
per  share,  or  an  aggregate  €453  million  (approximately 
$546  million)  including  related  fees.  Income  (loss)  from 
operating  affiliates  reflected  a  one-time  gain  of  $75  million 
realized  from  the  acquisition.  As  a  result  of  equity  method 
accounting  rules,  approximately  $36  million  of  additional 
gain was deferred and will generally be recognized over the 
next  five  years.  As  of  December  31,  2023,  the  Company 
owned approximately 29.9% of the issued shares of Coface, 
or 30.1% excluding treasury shares, with a carrying value of 
$570  million,  compared  to  $563  million  at  December  31, 
2022.

In July 2021, the Company announced the completion of the 
previously  disclosed  acquisition  of  Somers  by  Greysbridge 
for a cash purchase price of $35.00 per common share. 

Effective  July  1,  2021,  Somers  is  wholly  owned  by 
Greysbridge,  and  Greysbridge

10. Fair Value

Accounting  guidance  regarding  fair  value  measurements 
addresses  how  companies  should  measure  fair  value  when 
they are required to use a fair value measure for recognition 
or disclosure purposes under GAAP and provides a common 
definition  of  fair  value  to  be  used  throughout  GAAP.  It 
defines fair value as the price that would be received to sell 
an  asset  or  paid  to  transfer  a  liability  in  an  orderly  fashion 
between  market  participants  at  the  measurement  date.  In 
addition,  it  establishes  a  three-level  valuation  hierarchy  for 
the  disclosure  of  fair  value  measurements.  The  valuation 
hierarchy  is  based  upon  the  transparency  of  inputs  to  the 
valuation of an asset or liability as of the measurement date. 
The  level  in  the  hierarchy  within  which  a  given  fair  value 
measurement  falls  is  determined  based  on  the  lowest  level 
input  that  is  significant  to  the  measurement  (Level  1  being 
the highest priority and Level 3 being the lowest priority).

The levels in the hierarchy are defined as follows:

Level 1:

Level 2:

to 

Inputs 
the  valuation  methodology  are 
observable  inputs  that  reflect  quoted  prices 
(unadjusted)  for  identical  assets  or  liabilities  in 
active markets

Inputs  to  the  valuation  methodology  include 
quoted prices for similar assets and liabilities in 
active markets, and inputs that are observable for 
the asset or liability, either directly or indirectly, 
for  substantially  the  full  term  of  the  financial 
instrument

Level 3:

to 

Inputs 
the  valuation  methodology  are 
unobservable  and  significant  to  the  fair  value 
measurement

Following  is  a  description  of  the  valuation  methodologies 
used  for  securities  measured  at  fair  value,  as  well  as  the 
general  classification  of  such  securities  pursuant  to  the 
valuation  hierarchy.  The  Company  reviews  its  securities 
measured at fair value and discusses the proper classification 
of such investments with investment advisers and others.

to  provide 

The  Company  determines  the  existence  of  an  active  market 
based  on  its  judgment  as  to  whether  transactions  for  the 
financial  instrument  occur  in  such  market  with  sufficient 
frequency  and  volume 
reliable  pricing 
information.  The  independent  pricing  sources  obtain  market 
quotations  and  actual  transaction  prices  for  securities  that 
have  quoted  prices  in  active  markets.  The  Company  uses 
quoted  values  and  other  data  provided  by  nationally 
recognized  independent  pricing  sources  as  inputs  into  its 
process  for  determining  fair  values  of  its  fixed  maturity 
investments.  To  validate  the  techniques  or  models  used  by 
pricing sources, the Company's review process includes, but 
is not limited to: (i) quantitative analysis (e.g., comparing the 
quarterly  return  for  each  managed  portfolio  to  its  target 

benchmark,  with  significant  differences 
identified  and 
investigated);  (ii)  a  review  of  the  prices  obtained  in  the 
pricing  process  and  the  range  of  resulting  fair  values;  (iii) 
initial  and  ongoing  evaluation  of  methodologies  used  by 
outside  parties  to  calculate  fair  value;  (iv)  a  comparison  of 
the  fair  value  estimates  to  the  Company’s  knowledge  of  the 
current market; (v) a comparison of the pricing services' fair 
values  to  other  pricing  services'  fair  values  for  the  same 
investments;  and  (vi)  periodic  back-testing,  which  includes 
randomly  selecting  purchased  or  sold  securities  and 
comparing  the  executed  prices  to  the  fair  value  estimates 
from  the  pricing  service.  A  price  source  hierarchy  was 
maintained  in  order  to  determine  which  price  source  would 
be  used  (i.e.,  a  price  obtained  from  a  pricing  service  with 
more seniority in the hierarchy will be used over a less senior 
one  in  all  cases).  The  hierarchy  prioritizes  pricing  services 
based  on  availability  and  reliability  and  assigns  the  highest 
priority  to  index  providers.  Based  on  the  above  review,  the 
Company will challenge any prices for a security or portfolio 
which are considered not to be representative of fair value. 

In  certain  circumstances,  when  fair  values  are  unavailable 
from  these  independent  pricing  sources,  quotes  are  obtained 
directly 
the 
from  broker-dealers  who  are  active 
corresponding  markets.  Such  quotes  are  subject  to  the 
validation  procedures  noted  above.  Of  the  $29.6  billion  of 
financial  assets  and  liabilities  measured  at  fair  value  at 
December  31,  2023,  approximately  $14  million,  or  0.0%, 
were  priced  using  non-binding  broker-dealer  quotes.  Of  the 
$23.8  billion  of  financial  assets  and  liabilities  measured  at 
fair value at December 31, 2022, approximately $13 million, 
or 0.1%, were priced using non-binding broker-dealer quotes.

in 

Fixed maturities

The Company uses the market approach valuation technique 
to  estimate  the  fair  value  of  its  fixed  maturity  securities, 
when  possible.  The  market  approach  includes  obtaining 
prices  from  independent  pricing  services,  such  as  index 
providers  and  pricing  vendors,  as  well  as  to  a  lesser  extent 
quotes from broker-dealers. The independent pricing sources 
obtain  market  quotations  and  actual  transaction  prices  for 
securities  that  have  quoted  prices  in  active  markets.  Each 
source  has  its  own  proprietary  method  for  determining  the 
fair value of securities that are not actively traded. In general, 
these  methods  involve  the  use  of  “matrix  pricing”  in  which 
the independent pricing source uses observable market inputs 
including,  but  not  limited  to,  investment  yields,  credit  risks 
and  spreads,  benchmarking  of  like  securities,  broker-dealer 
quotes,  reported  trades  and  sector  groupings  to  determine  a 
reasonable fair value. The following describes the significant 
inputs  generally  used  to  determine  the  fair  value  of  the 
Company’s fixed maturity securities by asset class:

U.S.  government  and  government  agencies  –  valuations 
provided  by  independent  pricing  services,  with  all  prices 
provided  through  index  providers  and  pricing  vendors.  The 
Company  determined  that  all  U.S.  Treasuries  would  be 
classified  as  Level  1  securities  due  to  observed  levels  of 
trading  activity,  the  high  number  of  strongly  correlated 
pricing quotes received on U.S. Treasuries and other factors. 
The  fair  values  of  U.S.  government  agency  securities  are 
generally  determined  using  the  spread  above  the  risk-free 
yield curve. As the yields for the risk-free yield curve and the 
spreads for these securities are observable market inputs, the 
fair  values  of  U.S.  government  agency  securities  are 
classified within Level 2.

Corporate  bonds  –  valuations  provided  by  independent 
pricing services, substantially all through index providers and 
pricing vendors with a small amount through broker-dealers. 
The  fair  values  of  these  securities  are  generally  determined 
using  the  spread  above  the  risk-free  yield  curve.  These 
spreads  are  generally  obtained  from  the  new  issue  market, 
secondary  trading  and  from  broker-dealers  who  trade  in  the 
relevant security market. As the significant inputs used in the 
pricing  process  for  corporate  bonds  are  observable  market 
inputs, the fair value of these securities are classified within 
Level 2. A small number of securities are included in Level 3 
due  to  the  lack  of  an  available  independent  price  source  for 
such  securities.  As  the  significant  inputs  used  to  price  these 
securities  are  unobservable,  the  fair  value  of  such  securities 
are classified as Level 3.

Residential mortgage-backed securities – valuations provided 
by  independent  pricing  services,  substantially  all  through 
pricing  vendors  and  index  providers  with  a  small  amount 
through broker-dealers. The fair values of these securities are 
generally  determined  through  the  use  of  pricing  models 
(including  Option  Adjusted  Spread)  which  use  spreads  to 
determine  the  expected  average  life  of  the  securities.  These 
spreads  are  generally  obtained  from  the  new  issue  market, 
secondary  trading  and  from  broker-dealers  who  trade  in  the 
relevant  security  market.  The  pricing  services  also  review 
prepayment speeds and other indicators, when applicable. As 
the  significant  inputs  used  in  the  pricing  process  for 
mortgage-backed securities are observable market inputs, the 
fair value of these securities are classified within Level 2.

Municipal  bonds  –  valuations  provided  by  independent 
pricing  services,  with  all  prices  provided  through  index 
providers  and  pricing  vendors.  The  fair  values  of  these 
securities  are  generally  determined  using  spreads  obtained 
from  broker-dealers  who  trade  in  the  relevant  security 
market,  trade  prices  and  the  new  issue  market.  As  the 
significant  inputs  used  in  the  pricing  process  for  municipal 
bonds  are  observable  market  inputs,  the  fair  value  of  these 
securities are classified within Level 2.

Commercial  mortgage-backed 
securities  –  valuations 
provided  by  independent  pricing  services,  substantially  all 
through  index  providers  and  pricing  vendors  with  a  small 
amount  through  broker-dealers.  The  fair  values  of  these 
securities are generally determined through the use of pricing 
models  which  use  spreads  to  determine  the  appropriate 
average  life  of  the  securities.  These  spreads  are  generally 
obtained  from  the  new  issue  market,  secondary  trading  and 
from  broker-dealers  who  trade  in  the  relevant  security 
market. As the significant inputs used in the pricing process 
for  commercial  mortgage-backed  securities  are  observable 
market inputs, the fair value of these securities are classified 
within Level 2.

Non-U.S.  government  securities  –  valuations  provided  by 
independent  pricing  services,  with  all  prices  provided 
through index providers and pricing vendors. The fair values 
of these securities are generally based on international indices 
or  valuation  models  which  include  daily  observed  yield 
curves, cross-currency basis index spreads and country credit 
spreads. As the significant inputs used in the pricing process 
for  non-U.S.  government  securities  are  observable  market 
inputs, the fair value of these securities are classified within 
Level 2.

Asset-backed securities – valuations provided by independent 
pricing services, substantially all through index providers and 
pricing vendors with a small amount through broker-dealers. 
The  fair  values  of  these  securities  are  generally  determined 
through the use of pricing models (including Option Adjusted 
Spread)  which  use  spreads  to  determine  the  appropriate 
average  life  of  the  securities.  These  spreads  are  generally 
obtained  from  the  new  issue  market,  secondary  trading  and 
from  broker-dealers  who  trade  in  the  relevant  security 
market. As the significant inputs used in the pricing process 
for  asset-backed  securities  are  observable  market  inputs,  the 
fair value of these securities are classified within Level 2. A 
small  number  of  securities  are  included  in  Level  3  due  to  a 
low  level  of  transparency  on  the  inputs  used  in  the  pricing 
process.

Equity securities

The  Company  determined 
that  exchange-traded  equity 
securities  would  be  included  in  Level  1  as  their  fair  values 
are  based  on  quoted  market  prices  in  active  markets.  Other 
equity  securities  are  included  in  Level  2  of  the  valuation 
hierarchy. A small number of securities are included in Level 
3 due to the lack of an available independent price source for 
such  securities.  As  the  significant  inputs  used  to  price  these 
securities  are  unobservable,  the  fair  value  of  such  securities 
are classified as Level 3.

Other investments

Residential mortgage loans

The  Company’s  residential  mortgage  loans  (included  in 
‘other  assets’  in  the  consolidated  balance  sheets)  include 
amounts  related  to  the  Company’s  whole  mortgage  loan 
purchase  and  sell  program.  Fair  values  of  residential 
mortgage  loans  are  generally  determined  based  on  market 
prices. As significant inputs used in pricing process for these 
residential  mortgage  loans  are  observable  market  inputs,  the 
fair value of these securities are classified within Level 2.

Other liabilities

liabilities 

consideration 

The  Company’s  other  liabilities  include  contingent  and 
deferred  consideration  liabilities  related  to  the  Company’s 
acquisitions.  Contingent 
are 
remeasured  at  fair  value  at  each  balance  sheet  date  with 
changes  in  fair  value  recognized  in  ‘net  realized  gains 
the  fair  value  of  contingent 
(losses).’  To  determine 
consideration  liabilities,  the  Company  estimates  the  future 
payments using an income approach based on modeled inputs 
which  include  a  weighted  average  cost  of  capital.  Deferred 
consideration  liabilities  are  measured  at  fair  value  on  the 
transaction  date.  The  Company  determined  that  contingent 
and  deferred  consideration  liabilities  would  be  included 
within Level 3.

The  Company  determined  that  exchange-traded  investments 
would be included in Level 1 as their fair values are based on 
quoted  market  prices  in  active  markets.  Other  investments 
also include term loan investments for which fair values are 
estimated  by  using  quoted  prices  of  term  loan  investments 
with similar characteristics, pricing models or matrix pricing. 
Such  investments  are  generally  classified  within  Level  2.  A 
small number of securities are included in Level 3 due to the 
lack  of  an  available  independent  price  source  for  such 
securities. 

Derivative instruments

The  Company’s  futures  contracts,  foreign  currency  forward 
contracts,  interest  rate  swaps  and  other  derivatives  trade  in 
the  over-the-counter  derivative  market.  The  Company  uses 
the market approach valuation technique to estimate the fair 
value  for  these  derivatives  based  on  significant  observable 
market  inputs  from  third  party  pricing  vendors,  non-binding 
broker-dealer  quotes  and/or  recent  trading  activity.  As  the 
significant  inputs  used  in  the  pricing  process  for  these 
derivative  instruments  are  observable  market  inputs,  the  fair 
value of these securities are classified within Level 2. 

Short-term investments

The  Company  determined  that  certain  of  its  short-term 
investments  held  in  highly  liquid  money  market-type  funds, 
Treasury  bills  and  commercial  paper  would  be  included  in 
Level 1 as their fair values are based on quoted market prices 
in  active  markets.  The  fair  values  of  certain  short-term 
investments are generally determined using the spread above 
the  risk-free  yield  curve  and  are  classified  within  Level  2. 
Other short-term investments are included in Level 3 due to 
the  lack  of  an  available  independent  price  source  for  such 
securities. As the significant inputs used to price these short-
term  securities  are  unobservable,  the  fair  value  of  such 
securities are classified as Level 3.

Financial  Instruments  Disclosed,  But  Not  Carried,  At  Fair 
Value

The  Company  uses  various  financial  instruments  in  the 
normal  course  of  its  business.  The  carrying  values  of  cash, 
accrued  investment  income,  receivable  for  securities  sold, 
certain  other  assets,  payable  for  securities  purchased  and 
certain  other  liabilities  approximated  their  fair  values  at 
December 31, 2023, due to their respective short maturities. 
As  these  financial  instruments  are  not  actively  traded,  their 
respective fair values are classified within Level 2.

At  December  31,  2023,  the  Company’s  senior  notes  were 
carried at their cost, net of debt issuance costs, of $2.7 billion 
and had a fair value of $2.5 billion. At December 31, 2022, 
the Company’s senior notes were carried at their cost, net of 
debt  issuance  costs,  of  $2.7  billion  and  had  a  fair  value  of 
$2.4 billion. The fair values of the senior notes were obtained 
from a third party pricing service and are based on observable 
market  inputs.  As  such,  the  fair  value  of  the  senior  notes  is 
classified within Level 2.

Fair Value Measurements on a Non-Recurring Basis

The Company measures the fair value of certain assets on a 
non-recurring  basis,  generally  quarterly,  annually,  or  when 
events or changes in circumstances indicate that the carrying 
amount  of  the  assets  may  not  be  recoverable.  These  assets 
include  investments  accounted  for  using  the  equity  method, 
certain other investments, goodwill and intangible assets, and 
long-lived assets. The Company uses a variety of techniques 
to measure the fair value of these assets when appropriate, as 
described below: 

Investments accounted for using the equity method. When the 
Company  determines  that  the  carrying  value  of  these  assets 
may  not  be  recoverable,  the  Company  records  the  assets  at 
fair value with the loss recognized in income. In such cases, 
the Company measures the fair value of these assets using the 
techniques  discussed  above  in  “—Fair  Value  Measurements 
on a Recurring Basis.”

Goodwill and Intangible Assets. The Company tests goodwill 
and  intangible  assets  annually  for  impairment  whenever 
events  or  changes  in  circumstances  indicate  the  carrying 
amount  may  not  be  recoverable.  When  the  Company 
determines  goodwill  and  intangible  assets  may  be  impaired, 
the Company uses techniques including discounted expected 
future cash flows, to measure fair value.

Long-Lived  Assets.  The  Company  tests  its  long-lived  assets 
for impairment whenever events or changes in circumstances 
indicate the carrying amount of a long-lived asset may not be 
recoverable. 

11. Derivative Instruments

The  Company’s  investment  strategy  allows  for  the  use  of 
derivative 
derivative 
instruments.  The  Company’s 
instruments are recorded on its consolidated balance sheets at 
fair  value.  The  Company  utilizes  exchange  traded  U.S. 
Treasury  note,  Eurodollar  and  other  futures  contracts  and 
commodity futures to manage portfolio duration or replicate 
investment  positions  in  its  portfolios  and  the  Company 
foreign  currency 
routinely  utilizes 
forward  contracts, 
futures  contracts  and  other 
index 
currency  options, 
derivatives  as  part  of  its  total  return  objective.  In  addition, 
certain  of  the  Company’s  investments  are  managed  in 
portfolios  which  incorporate  the  use  of  foreign  currency 
forward contracts which are intended to provide an economic 
hedge against foreign currency movements.

TBAs in both long and short positions to enhance investment 
performance and as part of its overall investment strategy.

The  Company  did  not  hold  any  derivatives  which  were 
designated  as  hedging  instruments  at  December  31,  2023  or 
2022. 

The  Company’s  derivative  instruments  can  be  traded  under 
master  netting  agreements,  which  establish  terms  that  apply 
to all derivative transactions with a counterparty. In the event 
of  a  bankruptcy  or  other  stipulated  event  of  default,  such 
agreements provide that the non-defaulting party may elect to 
terminate  all  outstanding  derivative  transactions,  in  which 
case  all  individual  derivative  positions  (loss  or  gain)  with  a 
counterparty  are  closed  out  and  netted  and  replaced  with 
a  single  amount,  usually  referred  to  as  the  termination 
amount,  which  is  expressed  in  a  single  currency.  The 
resulting single net amount, where positive, is payable to the 
party  “in-the-money”  regardless  of  whether  or  not  it  is  the 
defaulting party, unless the parties have agreed that only the 
non-defaulting  party  is  entitled  to  receive  a  termination 
payment where the net amount is positive and is in its favor.

12. Variable Interest Entity and Noncontrolling Interests

Somers Holdings Ltd.

In  March  2014,  the  Company  invested  $100  million  and 
acquired  2,500,000  common  shares  of  Somers.  Somers  was 
considered a VIE and the Company concluded that it was the 
primary  beneficiary  of  Somers.  In  the  2020  fourth  quarter, 
Arch  Capital,  Somers  and  Greysbridge,  a  wholly-owned 
subsidiary  of  Arch  Capital,  entered  into  an  Agreement  and 
Plan of Merger (as amended, the “Merger Agreement”). The 
merger  and  the  related  Greysbridge  equity  financing  closed 
on  July  1,  2021.  Effective  July  1,  2021,  Somers  is  wholly 
owned  by  Greysbridge,  and  Greysbridge  is  owned  40%  by 
the Company, 30% by certain investment funds managed by 
Kelso  and  30%  by  certain  investment  funds  managed  by 
Warburg. Based on the governing documents of Greysbridge, 
the  Company  concluded  that,  while  it  retains  significant 
influence  over  Somers,  Somers  no  longer  constitutes  a 
variable  interest  entity.  Accordingly,  effective  July  1,  2021, 
the Company no longer consolidates the results of Somers in 
its  consolidated  financial  statements  and  footnotes.  The 
Company  classifies

The  Company  has  entered  into  aggregate  excess  of  loss 
mortgage  reinsurance  agreements  with  various  special 
purpose  reinsurance  companies  domiciled  in  Bermuda  (the 
“Bellemeade  Agreements”).  At  the  time  the  Bellemeade 
Agreements  were  entered  into,  the  applicability  of  the 
accounting guidance that addresses VIEs was evaluated. As a 
result  of  the  evaluation  of  the  Bellemeade  Agreements,  the 
Company  concluded  that  these  entities  are  VIEs.  However, 
given  that  the  ceding  insurers  do  not  have  the  unilateral 
power  to  direct  those  activities  that  are  significant  to  their 
economic  performance,  the  Company  does  not  consolidate 
such  entities  in  its  consolidated  financial  statements.  The 
reinsurance  premium  paid  in  regard  to  the  Bellemeade 
Agreements  is  calculated  by  multiplying  the  outstanding 
reinsurance  coverage  amount  at  the  beginning  of  the  period 
by the coupon rate, which is the SOFR plus a contractual risk 
margin,  less  the  actual  investment  income  collected  during 
the preceding month on the assets included in the underlying 
reinsurance  trusts.  In  the  event  the  assets  included  in  the 
underlying  reinsurance  trusts  (became  severely  impaired  or 
worthless  and  the  special  purpose  reinsurance  companies 
were unable to meet their future obligations, the Company’s 
mortgage  insurance  subsidiaries  would  be  liable  to  fulfill 
claim payments to policyholders. The Company’s maximum 
exposure to loss associated with these VIEs is determined as 
the  amount  of  mortgage  insurance  claim  payments  on  the 
insured  policies,  net  of  aggregate  reinsurance  payments 
previously  received,  up  to  the  full  aggregate  excess  of  loss 
reinsurance coverage amounts.

Income Taxes

Arch Capital is incorporated under the laws of Bermuda and, 
under current Bermuda law, is not obligated to pay any taxes 
in  Bermuda  based  upon  income  or  capital  gains.  The 
Company  has  received  a  written  undertaking  from  the 
Minister  of  Finance  in  Bermuda  under  the  Exempted 
Undertakings  Tax  Protection  Act  1966  assuring  that,  in  the 
event  that  any  legislation  is  enacted  in  Bermuda  imposing 
any tax computed on profits, income, gain or appreciation on 
any  capital  asset,  or  any  tax  in  the  nature  of  estate  duty  or 
inheritance  tax,  such  tax  will  not  be  applicable  to  Arch 
Capital  or  any  of  its  operations  until  March  31,  2035. 
However,  on  December  27,  2023,  the  Government  of 
Bermuda enacted the Bermuda CIT Act, which will become 
effective for tax years beginning on or after January 1, 2025. 
Given the potential for the new corporate income tax regime 
in Bermuda to supersede the Minister of Finance’s assurance, 
the Company is likely to become subject to taxes in Bermuda 
before March 31, 2035.

The Bermuda CIT Act will apply a 15% corporate income tax 
to  certain  Bermuda  constituent  entities  of  multi-national 

groups in fiscal years beginning on or after January 1, 2025. 
The  act  includes  a  provision  referred  to  as  the  economic 
transition adjustment, which is intended to provide a fair and 
equitable  transition  into  the  tax  regime.  Pursuant  to  this 
legislation,  the  Company  recorded  a  $1.18  billion  net 
deferred  income  tax  asset  in  the  fourth  quarter  of  2023, 
expected to be utilized predominantly over a 10-year period. 
The  Company  expects  to  incur  and  pay  increased  taxes  in 
Bermuda beginning in 2025.

Arch Capital and its non-U.S. subsidiaries will be subject to 
U.S.  federal  income  tax  only  to  the  extent  that  they  derive 
U.S. source income that is subject to U.S. withholding tax, or 
income  that  is  effectively  connected  with  the  conduct  of  a 
trade or business within the U.S. and is not exempt from U.S. 
tax  under  an  applicable  income  tax  treaty  with  the  U.S.,  or 
because  a  non-U.S.  subsidiary  has  elected  to  be  treated  as  a 
U.S. taxpayer. Arch Capital and its non-U.S. subsidiaries will 
be  subject  to  a  withholding  tax  on  dividends  from  U.S. 
investments and interest from certain U.S. payors (subject to 
reduction by any applicable income tax treaty). Arch Capital 
their 
and 
operations in a manner that will not cause them to be treated 
as  engaged  in  a  trade  or  business  in  the  United  States  and, 
therefore,  will  not  be  required  to  pay  U.S.  federal  income 

its  non-U.S.  subsidiaries

taxes  (other  than  U.S.  excise  taxes  on  insurance  and 
reinsurance premium and withholding taxes on dividends and 
certain  other  U.S.  source  investment  income).  However, 
because  there  is  uncertainty  as  to  the  activities  which 
constitute  being  engaged  in  a  trade  or  business  within  the 
United  States,  there  can  be  no  assurances  that  the  U.S. 
Internal  Revenue  Service  will  not  contend  successfully  that 
Arch Capital, or its non-U.S. subsidiaries that do not elect to 
become U.S. taxpayers, are engaged in a trade or business in 
the  United  States.  If  Arch  Capital  or  any  of  its  non-U.S. 
subsidiaries were subject to U.S. income tax, Arch Capital’s 
shareholders’  equity  and  earnings  could  be  materially 
adversely  affected.  Arch  Capital  has  subsidiaries  and 
branches  that  operate  in  various  jurisdictions  around  the 
world that are subject to tax in the jurisdictions in which they 
operate. The significant jurisdictions in which Arch Capital’s 
subsidiaries  and  branches  are  subject  to  tax  are  the  United 
States,  United  Kingdom,  Ireland,  Canada,  Switzerland, 
Australia and Denmark.

The effect of a change in tax laws or rates on deferred income 
tax assets and liabilities is recognized in income in the period 
in which such change is enacted. 

Deferred  income  tax  assets  and  liabilities  reflect  temporary 
differences  based  on  enacted  tax  rates  between  the  carrying 
amounts  of  assets  and  liabilities  for  financial  reporting  and 
income tax purposes.

The  Company  provides  a  valuation  allowance  to  reduce  the 
net value of certain deferred income tax assets to an amount 
which  management  expects  to  more  likely  than  not  be 
realized. As of December 31, 2023, the Company’s valuation 
allowance  was  $15  million,  compared  to  $7  million  at 
December  31,  2022.  The  valuation 
at 
December  31,  2023,  was  primarily  attributable  to  valuation 
allowances on the Company’s Australia, Gibraltar and Hong 
Kong operations and certain other deferred income tax assets 
relating to tax attributes that have a limited use.

operating  loss  (“NOL”)  carryforwards  that  are  subject  to  annual  usage
limitations  under  Section  382  of  the  Internal  Revenue  Code  (“the  Code”).
The  NOL  limitations  are  related  to  acquisitions  of  the  CMG  entities  in 
January  2014,  Ventus  Risk  Management  Inc.  in  August  2019,  and  Verifly 
Insurance Services, LLC, and Verifly USA Inc. in April 2023. In accordance
with Section 382 of the Code, utilization of the acquired NOLs is limited to
approximately  $2  million  per  year 
through  December  31,  2027,
approximately  $1  million  through  December  31,  2038,  and  $0.3  million 
thereafter.

The  Company’s  U.S.  mortgage  operations  are  eligible  for  a 
tax  deduction,  subject  to  certain  limitations,  under  Section 
832(e)  of  the  Code  for  amounts  required  by  state  law  or 
regulation  to  be  set  aside  in  statutory  contingency  reserves. 
The deduction is allowed only to the extent that the Company 
purchases  non-interest  bearing  U.S.  Mortgage  Guaranty  Tax 
and Loss Bonds (“T&L Bonds”) issued by the U.S. Treasury 
Department  in  an  amount  equal  to  the  tax  benefit  derived 
from  deducting  any  portion  of  the  statutory  contingency 
reserves.  T&L  Bonds  are  reflected  in  ‘other  assets’  on  the 
Company’s  balance  sheet  and  totaled  approximately  $42 
million  at  December  31,  2023,  compared  to  $12  million  at 
December 31, 2022.

Deferred  income  tax  liabilities  have  not  been  accrued  with 
respect to the undistributed earnings of the Company's U.S., 
U.K. and Ireland subsidiaries as it is the Company’s intention 
that  all  such  earnings  will  be  indefinitely  reinvested.  If  the 
earnings  were  to  be  distributed,  as  dividends  or  otherwise, 
such  amounts  may  be  subject  to  withholding  tax  in  the 
jurisdiction  of  the  paying  entity.  The  Company  does  not 
intend  to  indefinitely  reinvest  earnings  from  the  Company's 
Canada subsidiary, however, no income or withholding taxes 
have  been  accrued  as  the  Canada  subsidiary  does  not  have 
positive  cumulative  earnings  and  profits  and  therefore  a 
distribution  from  this  particular  subsidiary  would  not  be 
subject  to  income  taxes  or  withholding  taxes.  Potential  tax 
implications  of  repatriation  from  the  Company’s  unremitted 
earnings that are indefinitely reinvested are driven by facts at

the  time  of  distribution.  Therefore,  it  is  not  practicable  to 
estimate  the  income  tax  liabilities  that  might  be  incurred  if 
such  earnings  were  remitted.  Distributions  from  the  U.K.  or 
Ireland  would  not  be  subject  to  withholding  tax  and  no 
deferred income tax liability would need to be accrued. 

The  Company  recognizes  interest  and  penalties  relating  to 
unrecognized tax benefits in the provision for income taxes. 
As of December 31, 2023, the Company’s total unrecognized 
tax benefits, including interest and penalties, were $2 million.

As of December 31, 2023, the Company owns $35 million in 
aggregate principal amount of Somers 6.5% senior notes, due 
July 2, 2029.

The following table presents the contractual maturities of the 
Company's operating lease liabilities at December 31, 2023:

17. Leases

In the ordinary course of business, the Company renews and 
enters into new leases for office property and equipment. At 
the lease inception date, the Company determines whether a 
contract contains a lease and its classification as a finance or 
operating  lease.  Primarily  all  of  the  Company’s  leases  are 
classified  as  operating  leases.  The  Company’s  operating 
leases have remaining lease terms of up to 14 years, some of 
which include options to extend the lease term. The Company 
considers these options when determining the lease term and 
measuring  its  lease  liability  and  right-of-use  asset.  In 
addition, the Company’s lease agreements do not contain any 
material  residual  value  guarantees  or  material  restrictive 
covenants.

Short-term  operating  leases  with  an  initial  term  of  twelve 
months or less were excluded on the Company's consolidated 
balance  sheet  and  represent  an  inconsequential  amount  of 
operating lease expense. 

As most leases do not provide an implicit rate, the Company 
uses its incremental borrowing rate based on the information 
available at the lease commencement date in determining the 
present value of lease payments. 

Additional  information  regarding  the  Company’s  operating 
leases is as follows:

18. Commitments and Contingencies

Concentrations of Credit Risk

The  creditworthiness  of  a  counterparty  is  evaluated  by  the 
Company,  taking  into  account  credit  ratings  assigned  by 
independent  agencies.  The  credit  approval  process  involves 
an  assessment  of  factors,  including,  among  others,  the 
counterparty,  country  and  industry  credit  exposure  limits. 
Collateral may be required, at the discretion of the Company, 
on  certain  transactions  based  on  the  creditworthiness  of  the 
counterparty.

losses  and 

The areas where significant concentrations of credit risk may 
exist  include  unpaid  losses  and  loss  adjustment  expenses 
recoverable,  contractholder  receivables,  ceded  unearned 
premiums,  paid 
loss  adjustment  expenses 
recoverable net of reinsurance balances payable, investments 
and  cash  and  cash  equivalent  balances.  A  credit  exposure 
exists  with  respect  to  reinsurance  recoverables  as  they  may 
become  uncollectible.  The  Company  manages  its  credit  risk 
in its reinsurance relationships by transacting with reinsurers 
that  it  considers  financially  sound  and,  if  necessary,  the 
Company  may  hold  collateral  in  the  form  of  funds,  trust 
accounts  and/or  irrevocable  letters  of  credit.  This  collateral 
can  be  drawn  on  for  amounts  that  remain  unpaid  beyond 
specified  time  periods  on  an  individual  reinsurer  basis.  In 
addition, certain insurance policies written by the Company’s 
insurance operations feature large deductibles, primarily in its 
construction  and  national  accounts  lines  of  business.  Under 
such contracts, the Company is obligated to pay the claimant 
is 
for 
the  full  amount  of 
subsequently  reimbursed  by 
the 
deductible  amount.  These  amounts  are  included  on  a  gross 
basis  in  the  consolidated  balance  sheet  in  contractholder 
payables  and  contractholder  receivables,  respectively.  In  the 
event  that  the  Company  is  unable  to  collect  from  the 
liable  for  such 
policyholder, 

the  claim.  The  Company 

the  Company  would  be 

the  policyholder  for

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

defaulted amounts. Collateral, primarily in the form of letters 
of credit, cash and trusts, is obtained from the policyholder to 
mitigate the Company’s credit risk. In the instances where the 
company  receives  collateral  in  the  form  of  cash,  the 
Company  records  a  related  liability  in  “Collateral  held  for 
insured obligations.”

In addition, the Company underwrites a significant amount of 
its  business  through  brokers  and  a  credit  risk  exists  should 
any  of  these  brokers  be  unable  to  fulfill  their  contractual 
obligations  with  respect  to  the  payments  of  insurance  and 
reinsurance  balances  owed  to  the  Company.  The  following 
table  summarizes  the  percentage  of  the  Company’s  gross 
premiums  written  generated  from  or  placed  by  the  largest 
brokers:

Employment and Other Arrangements

At  December  31,  2023,  the  Company  has  entered  into

Letter of Credit and Revolving Credit Facilities

In  the  normal  course  of  its  operations,  the  Company  enters 
into  agreements  with  financial  institutions  to  obtain  secured 
and  unsecured  credit  facilities.  On  August  23,  2023,  Arch 
Capital  and  certain  of  its  subsidiaries  amended  the  existing 
credit agreement (the “Credit Facility”). The Credit Facility, 
as  amended,  consists  of  a  $425  million  secured  facility  for 
letters  of  credit  (the  “Secured  Facility”)  and  a  $500  million 
unsecured  facility  for  revolving  loans  and  letters  of  credit 
(the  “Unsecured  Facility”).  At  December  31,  2023,  the 
Secured  Facility  had  $273  million  of  letters  of  credit 
outstanding and remaining capacity of $152 million, and the 
Unsecured  Facility  had  no  outstanding  revolving  loans  or 
letters of credit, with remaining capacity of $500 million.

The  Credit  Facility  contains  certain 
restrictive  and 
maintenance  covenants  customary  for  facilities  of  this  type, 
including 
indebtedness,  minimum 
consolidated  tangible  net  worth,  maximum  leverage  levels 
and minimum financial strength ratings. Arch Capital and its 
subsidiaries  which  are  party  to  the  agreement  were  in 
compliance  with  all  covenants  contained 
therein  at 
December 31, 2023.

Obligations  of  each  borrower  for  letters  of  credit  under  the 
Secured Facility are secured by cash and eligible securities of 
such borrower and held in collateral accounts. Commitments 
under  the  Credit  Facility  may  be  increased  up  to,  but  not 
exceeding,  an  aggregate  of  $1.5  billion.  Arch  Capital  has  a

the  revolving 

one-time  option  to  convert  any  or  all  outstanding  revolving 
loans of Arch Capital and/or Arch-U.S. to term loans with the 
same 
that  any 
prepayments  may  not  be  re-borrowed.  Borrowings  of 
revolving  loans  may  be  made  at  a  variable  rate  based  on 
Secured Overnight Financing Rate (“SOFR”). Secured letters 
of credit are available for issuance on behalf of certain Arch 
Capital subsidiaries. Arch Capital guarantees the obligations 
of  Arch-U.S.  and  Arch  U.S.  MI  Holdings  Inc.,  Arch-U.S. 
guarantees the obligations of Arch Capital, and Arch Capital 
Finance LLC guarantees the obligations of Arch Capital and 
Arch-U.S. 

The  commitments  under  the  Credit  Facility  will  expire  on 
August  23,  2028,  and  all  loans  then  outstanding  under  the 
Credit Facility must be repaid at such time. Letters of credit 
issued  under  the  Credit  Facility  will  not  have  an  expiration 
date later than August 23, 2029.

On September 27, 2023, Arch Re Bermuda a wholly-owned 
subsidiary  of  Arch  Capital,  entered  as  the  borrower  into  a 
Letter  of  Credit  Facility  Agreement  with  Lloyds  Bank 
Corporate  Markets  plc.  Such  agreement  provides  for  a 
$175  million  unsecured  facility  for  letters  of  credit  with 
commitments  expiring  on  September  27,  2025.  At 
December  31,  2023,  this  facility  had  $114  million  of  letters 
of credit outstanding and remaining capacity of $61 million.

On  October  25,  2023,  Arch  Re  Bermuda  entered  into 
Amendment No. 3 and Joinder to a Letter of Credit Facility 
Agreement with Lloyds Bank Corporate Markets plc., which 
amends  the  agreement  dated  as  of  November  3,  2020,  as 
amended  on  October  29,  2021  and  as  further  amended  on 
October  27,  2022.  Such  agreement  provides 
for  a 
$530 million facility for letters of credit in respect of Tier 2 
Funds  at  Lloyds.  As  of  December  31,  2023,  $530  million 
face  amount  of  letters  of  credit  had  been  issued  under  this 
facility. The availability period ends on May 31, 2024.

In  addition,  certain  of  Arch  Capital’s  subsidiaries  had 
outstanding secured letters of credit through other facilities of 
$38  million,  which  were  issued  in  the  normal  course  of 
business  (“LOC  Facilities”).  The  principal  purpose  of  the 
LOC  Facilities  is  to  issue,  as  required,  evergreen  standby 
letters of credit in favor of primary insurance or reinsurance 
counterparties  with  which  certain  of  Arch  Capital’s 
subsidiaries has entered into reinsurance arrangements. 

When  issued,  all  secured  letters  of  credit  are  secured  by  a 
portion  of  the  investment  portfolio.  At  December  31,  2023, 
these letters of credit were secured by investments with a fair 
value  of  $550  million.  The  Company  had  no  outstanding 
revolving credit agreement borrowings at December 31, 2023 
and 2022.

Share Repurchase Program

The  Board  of  Directors  of  Arch  Capital  (the  “Board”)  has 
authorized  the  investment  in  Arch  Capital’s  common  shares 
through a share repurchase program. At December 31, 2023, 
$1.0  billion  of  share  repurchases  were  available  under  the 
program.  Repurchases  under  the  program  may  be  effected 
from  time  to  time  in  open  market  or  privately  negotiated 
transactions  through  December  31,  2024.  The  timing  and 
amount  of  the  repurchase  transactions  under  this  program 
will  depend  on  a  variety  of  factors,  including  market 
conditions and corporate and regulatory considerations. 

Repurchases of Arch Capital’s common shares in connection 
with  the  share  repurchase  plan  and  other  share-based 
transactions were held in the treasury under the cost method, 
and  the  cost  of  the  common  shares  acquired  is  included  in 
‘Common shares held in treasury, at cost.’ At December 31, 
2023, Arch Capital held 218.5 million shares for an aggregate 
cost of $4.4 billion in treasury, at cost.

The  Company’s  repurchases  under  the  share  repurchase 
program were as follows:

Series G Preferred Shares

In  June  2021,  Arch  Capital  completed  a  $500  million 
underwritten public offering of 20.0 million depositary shares
(the  “Depositary  Shares”),  each  of  which  represents  a

Preferred  Shares”).  Each  Depositary  Share,  evidenced  by  a 
depositary receipt, entitles the holder, through the depositary,
to  a  proportional  fractional  interest  in  all  rights  and 
preferences  of  the  Series  G  Preferred  Shares  represented 
thereby (including any dividend, liquidation, redemption and 
voting rights).

(equivalent 

Holders  of  Series  G  Preferred  Shares  will  be  entitled  to 
receive dividend payments only when, as and if declared by 
the Board or a duly authorized committee of the Board. Any 
such dividends will be payable from, and including, the date 
of  original  issue  on  a  noncumulative  basis,  quarterly  in 
arrears  on  the  last  day  of  March,  June,  September  and 
December  of  each  year,  at  an  annual  rate  of  4.55%. 
Dividends  on  the  Series  G  Preferred  Shares  are  not 
cumulative.  The  Company  will  be  restricted  from  paying 
dividends  on  or  repurchasing  its  common  shares  unless 
certain  dividend  payments  are  made  on  the  Series  G 
Preferred  Shares.  The  Company  may  not  declare  or  pay  a 
dividend  on  the  Series  G  Preferred  Shares  under  certain 
circumstances,  including  if  the  Company  is  or,  after  giving 
effect  to  such  payment,  would  be  in  breach  of  applicable 
individual  or  group  solvency  and  liquidity  requirements  or 
applicable individual or group enhanced capital requirements 
(“ECR”).  The  Series  G  Preferred  Shares  may  not  be 
redeemed  at  any  time  if  the  ECR  would  be  breached 
immediately before or after giving effect to such redemption, 
unless  the  Company  replaces  the  capital  represented  by 
preference shares to be redeemed with capital having equal or 
better capital treatment.

Long Term Incentive and Share Award Plans

The  Company  utilizes  share-based  compensation  plans  for 
officers,  other  employees  and  directors  of  Arch  Capital  and 
its  subsidiaries 
to  provide  competitive  compensation 
opportunities,  to  encourage  long-term  service,  to  recognize

individual  contributions  and 
performance  goals  and  to  promote  the  creation  of  long-term 
value  for  shareholders  by  aligning  the  interests  of  such 
persons with those of shareholders.

The 2022 Long-Term Incentive and Share Award Plan (“the 
2022  Plan”)  became  effective  as  of  May  4,  2022  following 
approval  by  shareholders  of  the  Company.  The  2022  Plan

rights,  restricted  shares,  restricted  share  units  payable  in 
common  shares  or  cash,  dividend  equivalents,  performance 
shares  and  performance  units  and  other  share-based  awards 
to  Arch  Capital’s  eligible  employees  and  directors.  The

The  Company’s  Bermuda 
reinsurance 
subsidiaries  are  subject  to  the  Bermuda  Insurance  Act  1978 
and  related  regulations,  each  as  amended  (the  “Insurance 
the  Company’s  principal 
Act”).  Arch  Re  Bermuda, 
reinsurance and insurance subsidiary, is registered as a Class 
4 
insurer  while  Arch  Group 
Reinsurance  Ltd.  (“AGRL”)  is  registered  as  a  Class  3A 
general  business  insurer  and  provides  affiliated  quota  share 
reinsurance  covering  certain  U.S.  business.  The  Insurance 
Act  requires  that  both  entities  maintain  minimum  statutory 
capital  and  surplus  equal  to  the  greater  of  a  minimum 
solvency  margin  and  the  enhanced  capital  requirement 
(“ECR”) as determined by the Bermuda Monetary Authority 
(“BMA”).  The  ECR  is  calculated  based  on  the  Bermuda 
Solvency  Capital  Requirement  model,  a  risk-based  model 
that  takes  into  account  the  risk  characteristics  of  different 
aspects  of  the  company’s  business.  At  December  31,  2023 
and  2022,  the  actual  and  required  capital  and  surplus  were 
based on the economic balance sheet requirements.

Under  the  Insurance  Act,  Arch  Re  Bermuda  and  AGRL  are 
restricted  with  respect  to  the  payment  of  dividends.  Each 
entity is prohibited from declaring or paying in any financial 
year dividends of more than 25% of its total statutory capital 

and  surplus  (as  shown  on  its  previous  financial  year’s 
statutory  balance  sheet)  unless  it  files,  at  least  seven  days 
before payment of such dividends, with the BMA an affidavit 
stating  that  it  will  continue  to  meet  the  required  margins 
following  the  declaration  of  those  dividends.  Accordingly, 
Arch  Re  Bermuda  can  pay  approximately  $4.8  billion  to 
Arch  Capital  during  2024  without  providing  an  affidavit  to 
the BMA. Dividends or distributions, if any, made by AGRL 
would result in an increase in available capital at Arch-U.S.

Ireland

The  Company  has  three  Irish  subsidiaries:  Arch  Re  Europe, 
an  authorized  life  and  non-life  reinsurer,  Arch  Insurance 
(EU),  an  authorized  non-life  insurer  and  Arch  Underwriting 
Europe, a registered insurance and reinsurance intermediary. 
Irish  authorized  reinsurers  and  insurers,  such  as  Arch  Re 
Europe,  Arch  Insurance  (EU)  and  Irish  intermediaries,  such 
as Arch Underwriters Europe, are also subject to the general 
body of Irish laws and regulations including the provisions of 
the  Companies  Act  2014.  As  part  of  the  Company’s  Brexit 
plan,  Arch  Insurance  (EU)  received  approval  from  the 
Central  Bank  of  Ireland  (“CBI”)  to  expand  the  nature  of  its 
business  in  2019  commenced  writing  insurance  lines  in  the 
European Economic Area in 2020, and the Part VII Transfer 
was  completed  at  the  end  of  December  2020.  Arch  Re 
Europe, Arch Insurance (EU) and Arch Underwriters Europe 
are  subject  to  the  supervision  of  the  CBI  and  must  comply 
with  Irish  insurance  acts  and  regulations  as  well  as  with 
directions and guidance issued by the CBI. Arch Re Europe 
and Arch Insurance (EU) are required to maintain a minimum 
level  of  capital.  At  December  31,  2023  and  2022,  these 
requirements were met.

The  amount  of  dividends  these  subsidiaries  are  permitted  to 
declare  is  limited  to  accumulated,  realized  profits,  so  far  as 
not  previously  utilized  by  distribution  or  capitalization,  less 
its  accumulated,  realized  losses,  so  far  as  not  previously 
written  off  in  a  reduction  or  reorganization  of  capital  duly 
made.  The  solvency  and  capital  requirements  must  still  be 
met following any distribution. Dividends or distributions, if 
any, made by Arch Re Europe would result in an increase in 
available capital at Arch Re Bermuda.

United States

The  Company’s  U.S.  insurance  and  reinsurance  subsidiaries 
are  subject  to  insurance  laws  and  regulations  in  the 
jurisdictions  in  which  they  operate.  The  ability  of  the 
Company’s regulated insurance subsidiaries to pay dividends 
or  make  distributions  is  dependent  on  their  ability  to  meet 
applicable  regulatory  standards.  These  regulations  include 
restrictions  that  limit  the  amount  of  dividends  or  other 
distributions,  such  as  loans  or  cash  advances,  available  to 
shareholders  without  prior  approval  of 
insurance 
regulatory authorities.

Dividends  or  distributions,  if  any,  made  by  Arch  Re  U.S. 
would result in an increase in available capital at Arch-U.S., 
the  Company’s  U.S.  holding  company.  Arch  Re  U.S.  can 
declare  a  maximum  of  approximately  $329  million  of 
dividends  during  2024  subject  to  the  approval  of  the 
Commissioner of the Delaware Department of Insurance. 

AMIC  and  UGRIC  are  approved  as  eligible  mortgage 
insurers  by  Fannie  Mae  and  Freddie  Mac,  subject  to 
(“eligible  mortgage

comprehensive, 
the  Private 
Mortgage  Insurer  Eligibility  Requirements  or  “PMIERs.” 
Revised  and  restated  in  September  2018,  and  clarified

by  the  GSEs  in  2020  and  2021,  respectively,  the  PMIERs

not apply to AMG, which is not GSE-approved.

requirements,  known  as 

The amount of assets required to satisfy the revised financial 
requirements  of  the  PMIERs  may  be  affected  by  many 
factors,  including  macro-economic  conditions,  the  size  and 
composition  of  our  mortgage  insurance  portfolio,  and  the 
amount  of  risk  ceded  to  reinsurers  that  may  be  deducted  in 
our calculation of “minimum required assets.” 

The  Company’s  U.S.  mortgage  insurance  subsidiaries  are 
subject  to  regulation  by  their  domiciliary  and  primary 
regulators,  the  Wisconsin  Office  of  the  Commissioner  of 
Insurance (“Wisconsin OCI”) for AMIC and AMG, the North 
Carolina  Department  of  Insurance  (“NC  DOI”)  for  UGRIC, 
and  by  state  insurance  departments  in  each  state  in  which 
they  are  licensed.  As  mandated  by  state  insurance  laws, 
mortgage  insurers  are  generally  mono-line  companies.  Each 
company  is  subject  to  the  statutory  requirements  of  their 
domiciliary  regulator  as  to  payment  of  dividends  and  return 
of  capital;  the  GSEs  may  also  impart  limitations  on  the 
Company’s  eligible  mortgage  insurers,  such  as  required 
minimum assets. Under respective state law, the Company’s 
U.S.  mortgage  subsidiaries  can  declare  a  maximum  of 
approximately  $180  million  of  ordinary  dividends  in  2024, 
however,  dividend  capacity  is  limited  by  the  respective 
companies  unassigned  surplus  amounts.  Such  dividends 
would  increase  the  available  capital  at  Arch  U.S.  MI 
Holdings Inc., a subsidiary of Arch-U.S. 

Mortgage  insurance  companies  licensed  in  Wisconsin  or 
North  Carolina  are  required  to  establish  contingency  loss 
reserves  for  purposes  of  statutory  accounting  in  an  amount 
equal to at least 50% of net earned premiums. These amounts 
generally  cannot  be  withdrawn  for  a  period  of  10  years  and 
are  separate  liabilities  for  statutory  accounting  purposes, 
which  affects  the  ability  to  pay  dividends.  However,  with 
prior  regulatory  approval,  a  mortgage  insurance  company 
may  make  early  withdrawals  from  the  contingency  reserve 

when incurred losses exceed 35% of net premiums earned in 
a calendar year.

Under Wisconsin and North Carolina law, as well as that of 
14 other states, a mortgage insurer must maintain a minimum 
amount of statutory capital relative to its risk in force in order 
for  the  mortgage  insurer  to  continue  to  write  new  business. 
While  formulations  of  minimum  capital  vary  in  certain 
jurisdictions, the most common measure applied allows for a 
maximum  risk-to-capital  ratio  of  25  to  1.  Wisconsin  and 
North  Carolina  require  mortgage  insurers  to  maintain  a 
“minimum  policyholder  position”  calculated  in  accordance 
with  their  respective  regulations.  Policyholders'  position 
consists primarily of statutory policyholders' surplus plus the 
contingency loss reserves.

United Kingdom

The  Prudential  Regulation  Authority  (“PRA”)  and  the 
Financial Conduct Authority (“FCA”) regulate insurance and 
reinsurance companies and the FCA regulates firms carrying 
on insurance mediation activities operating in the U.K., both 
under the Financial Services and Markets Act 2000. In May 
2004,  Arch  Insurance  (U.K.)  was  granted  the  relevant 
permissions  for  the  classes  of  insurance  business  which  it 
underwrites  in  the  U.K.  AMAL  currently  manages  Arch 
Syndicate  2012  and  Arch  Syndicate  1955  pursuant  to  its 
authorizations  by  the  U.K.  regulators  and  Lloyd’s.  All  U.K. 
companies are also subject to a range of statutory provisions, 
including  the  laws  and  regulations  of  the  Companies  Act 
2006 (as amended) (the “U.K. Companies Act”).

Arch Insurance (U.K.) and AMAL must maintain a margin of 
solvency at all times under the Solvency II Directive from the 
European  Insurance  and  Occupational  Pensions  Authority. 
The  regulations  stipulate  that  insurers  are  required  to 
maintain  the  minimum  capital  requirement  and  solvency 
capital  requirement  at  all  times.  At  December  31,  2023  and 
2022, these requirements were met.

As  corporate  members  of  Lloyd’s,  AMAL  (as  managing 
agent  of  the  Company’s  Lloyd’s  Syndicates)  and  each 
syndicate’s  respective  corporate  members  are  subject  to  the 
oversight  of  the  Council  of  Lloyd’s.  The  capital  required  to 
support  a  Syndicate’s  underwriting  capacity,  or  funds  at 
Lloyd’s, is assessed annually and is determined by Lloyd’s in 
accordance with the capital adequacy rules established by the 
PRA.  The  Company  has  provided  capital  to  support  the 
underwriting  of  Arch  Syndicate  2012  and  Arch  Syndicate 
1955  in  the  form  of  pledged  assets  and  letters  of  credit 
provided  by  Arch  Re  Bermuda.  The  amount  which  the 
Company  provides  as  funds  at  Lloyd’s  is  not  available  for 
distribution  to  the  Company  for  the  payment  of  dividends. 
Lloyd’s is supervised by the PRA and required to implement 
certain rules prescribed by the PRA under the Lloyd’s Act of 
1982  regarding  the  operation  of  the  Lloyd’s  market.  With

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

In  connection  with  the  filing  of  this  Form  10-K,  our 
management,  including  the  Chief  Executive  Officer  and 
Chief  Financial  Officer,  conducted  an  evaluation  of  our 
disclosure controls and procedures, as of December 31, 2023, 
for  the  purposes  set  forth  in  the  applicable  rules  under  the 
Securities  and  Exchange  Act  of  1934,  as  amended  (the 
“Exchange  Act”).  Based  on  that  evaluation,  the  Chief 
Executive Officer and Chief Financial Officer concluded that, 
as  of  December  31,  2023,  the  disclosure  controls  and 
procedures were effective.

We  continue  to  enhance  our  operating  procedures  and 
internal controls (including information technology initiatives 
and  controls  over  financial  reporting)  to  effectively  support 
our  business  and  our  regulatory  and  reporting  requirements. 
Our management does not expect that our disclosure controls 
or our internal controls will prevent all errors and all fraud. A 
control system, no matter how well conceived and operated, 
can provide only reasonable, not absolute, assurance that the 
objectives of the control system are met. Further, the design 
of  a  control  system  must  reflect  the  fact  that  there  are 
resource  constraints,  and  the  benefits  of  controls  must  be 
considered relative to their costs. As a result of the inherent 
limitations  in  all  control  systems,  no  evaluation  of  controls 
can  provide  absolute  assurance  that  all  control  issues  and 
instances  of  fraud,  if  any,  within  the  company  have  been 
detected. These inherent limitations include the realities that 
judgments  in  decision  making  can  be  faulty,  and  that 
breakdowns  can  occur  because  of  simple  error  or  mistake. 
Additionally, controls can be circumvented by the individual 
acts of some persons or by collusion of two or more people. 

The  design  of  any  system  of  controls  also  is  based  in  part 
upon  certain  assumptions  about  the  likelihood  of  future 
events,  and  there  can  be  no  assurance  that  any  design  will 
succeed in achieving its stated goals under all potential future 
conditions;  over  time,  controls  may  become  inadequate 

in  conditions,  or 

because  of  changes 
the  degree  of 
compliance  with  the  policies  or  procedures  may  deteriorate. 
As  a  result  of  the  inherent  limitations  in  a  cost-effective 
control system, misstatement due to error or fraud may occur 
and not be detected. Accordingly, our disclosure controls and 
procedures are designed to provide reasonable, not absolute, 
assurance that the disclosure controls and procedures are met.

Management’s  Annual  Report  on  Internal  Control  Over 
Financial Reporting

internal  control  over 

Our  management 
is  responsible  for  establishing  and 
financial 
maintaining  adequate 
reporting, as defined in Rules 13a-15(f) and 15d-15(f) under 
the  Exchange  Act.  Our  management  assessed 
the 
effectiveness  of  our  internal  control  over  financial  reporting 
as  of  December  31,  2023.  In  making  this  assessment, 
management  used  the  criteria  set  forth  by  the  Committee  of 
Sponsoring  Organizations 
the  Treadway 
(COSO)  of 
Commission 
in  Internal  Control-Integrated  Framework 
(2013).

Based on our assessment, management determined that, as of 
December  31,  2023,  our  internal  control  over  financial 
reporting  was  effective.  The  effectiveness  of  our  internal 
control over financial reporting as of December 31, 2023 has 
been 
an 
audited  by  PricewaterhouseCoopers  LLP, 
independent  registered  public  accounting  firm,  as  stated  in 
their report included in Item 8.

Changes in Internal Control Over Financial Reporting

There have been no changes in internal control over financial 
reporting  that  occurred  in  connection  with  our  evaluation 
required  pursuant  to  Rules  13a-15  and  15d-15  under  the
