TO OUR SHAREHOLDERS

It’s a good time to be at Arch. Last year, the power of our diversified platform 

was on full display as we produced record-breaking results in both premium 

growth and underwriting income while delivering an operating return on 

average common equity of 14.8%*. The accelerated growth in our property 

and casualty (P&C) segments, along with the earnings contributions from 

our mortgage segment, propelled Arch to a leading position in the specialty 

insurance sector. Equally important, our ability to execute our strategy over 

the past several years has positioned Arch and our shareholders to benefit 

from the market opportunities ahead. Creating solutions for managing risk 

is at the core of our company and continues to evolve in an increasingly 

unpredictable world. Our addition to the S&P 500 in the fourth quarter serves 

as a recognition of our ability to navigate uncertainty while delivering long-term 

underwriting excellence. 

While 2022 was a terrific year for Arch and our shareholders, we remain bullish 

about what’s ahead. Overall market conditions continue to be favorable, 

and our diversified platform gives us flexibility on how to maximize our 

opportunities. Our growth in recent years has been rapid, but we firmly believe 

there is more we can do in this market.

Long-term shareholders will not be surprised by our success. Our strategy is 

straightforward. First, focus on underwriting specialty lines where knowledge 

and expertise provide a competitive advantage. Second, hire outstanding, 

solution-oriented people who live our Values. Third, allocate capital to the 

most attractive opportunities while following our cycle management strategy 

that encourages our underwriting teams to grow during favorable market 

conditions and remain cautious in the soft period of the underwriting cycle.

Arch’s accelerated growth and excellent overall results over the past few 

years are the product of successfully executing this strategy. Disciplined cycle 

management during the most recent soft P&C market limited our exposure 

to inadequately priced business and ensured we had ample capacity available 

when opportunities emerged. In addition, as pricing became more favorable, 

our underwriters and claims managers leveraged their specialty experience to 

provide creative solutions to our brokers and clients — resulting in a record 

$15.3 billion of gross premiums written in 2022.

Against the backdrop of a very challenging year for insurers 

INSURANCE

that included the war in Ukraine, persistent inflation, low 

fixed-income and equity returns and another active natural 

catastrophe year, each of our three underwriting segments 

delivered excellent returns. Over the past four years, we 

have nearly tripled our total P&C net premiums written, not 

a small feat given our already robust market presence. At the 

same time, our mortgage group once again demonstrated 

the diversification power of that business by delivering record 

underwriting income. Last year, our shareholders were 

rewarded with a healthy increase in our share price over 2021.

Underwriting Results

Underwriting income across the three underwriting segments 

was a record $1.8 billion* in 2022, advancing 45% from 2021. 

In 2022, net premiums written increased 21% to $5.0 billion and 

underwriting income nearly doubled to $225 million from $117 

million in 2021. Our growth in 2022 is a direct result of our U.S. 

and UK teams’ ability to capitalize on the significant investments 

we’ve made over the past five years to enhance our global 

platform in preparation for hard market opportunities. Since the 

early days of the hard market in 2019, our insurance segment 

has more than doubled its net premiums written and enhanced 

its contribution to the underwriting income of the enterprise.

Rate increases for most lines exceeded loss cost trends 

as our underwriting teams deployed our capacity into the 

most profitable lines. Premium growth in 2022 came from a 

diverse mix of coverages such as travel, accident and health 

insurance and professional lines (including cyber) and excess

Investable assets totaled $28.1 billion at the end of 2022, 

increasing slightly from 2021. Assets were bolstered by $3.8 

billion from net cash flow provided by operating activities. 

While rising interest rates negatively impacted the market 

value of many of the securities in our portfolio, they helped us 

generate more investment income on new money invested. 

Investment income was $497 million in 2022, increasing 43%

We continue to take a cautious approach toward duration

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 2.9 years. 

In addition to investing in fixed-income securities, we invest a 

portion of the portfolio in equities and alternative investments, 

which have both contributed positively to our bottom line over 

the years, albeit with more volatility than our fixed income 

portfolio. 

Capital Management

Our reputation as an astute capital allocator is one we are 

proud of and do not take lightly. We maintain a conservative

obligations to clients and provide the financial resources to 

take advantage of business opportunities as they arise. At 

year-end 2022, we maintained a conservative level of financial

The strength of our balance sheet provided a competitive 

advantage in 2022. As the P&C market hardened further, we 

had ample resources to quickly write more business and serve 

the needs of clients in the marketplace. 

We are responsible stewards of the capital entrusted to us, 

and we carefully weigh opportunities in how we deploy that 

capital. In 2022, we repurchased $586 million of Arch common 

shares, almost entirely in the first half of the year. In the second 

half of the year, burgeoning opportunities in the P&C market 

encouraged us to allocate capital to fuel that growth — which 

should be reflected in our results in the coming years.

10  |  Arch Capital Group Ltd. 2022 Annual Report

In a year when economic uncertainty and increasing mortgage interest rates hampered new mortgage originations 
worldwide, especially in the U.S., Arch MI leveraged the overall strength of its portfolio to deliver a record $1.3 billion of 
underwriting income — a 32% increase from 2021. As a diversified business across industry sectors, Arch MI has the flexibility 
to focus on relative returns and allocate capital to the best opportunities. Insurance in force, the earnings foundation for the 
segment, grew 11% from Dec. 31, 2021, to $513.1 billion in 2022. The credit quality of Arch MI’s embedded book remains 
excellent, and we believe the segment is well positioned for most housing market scenarios.

2022 HIGHLIGHTS

	 Arch MI U.S. had a delinquency rate of 1.77%, 
as of Dec. 31, 2022, which was 59 basis points 
lower than year end 2021.

   Finished 2022 with a -7.7% combined 

ratio — driven by prior year development 
from reserves posted during COVID-19 
uncertainty. 

   Helped more than 211,000 borrowers in the 

U.S. purchase or refinance a home.

	 More than 28% of the segment’s

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 64–66 of the Company’s Annual Report on Form 10-K, filed 
with the SEC on Feb. 24, 2023 (the “Form 10-K”), 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.

Through June 30, 2021, each line item in our consolidated financial data reflected the impact of our percentage ownership of Somers’ (formerly Watford 
Holdings Ltd.) common equity. In July 2021, the Company announced the completion of the previously disclosed acquisition of Somers by Greysbridge Holdings 
Ltd. (“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. Effective July 1, 2021, Arch no longer consolidates the results of Somers in its consolidated financial 
statements and footnotes.

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, income taxes and 
loss on redemption of preferred shares. 

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. Each line item reflects the impact of the Company’s ownership of 
Somers’ outstanding common equity through June 30, 2021:

(in millions)

Net income available to Arch common shareholders (a)

Net realized (gains) losses

Equity in net (income) of investment funds accounted for using the equity method

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 or 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 111-117 to the consolidated financial statements in our 2022 
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, and a combined ratio excluding 
prior year development, for the mortgage segment 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:

Current accident year catastrophic events, net of reinsurance and reinstatement premiums

Net (favorable) adverse development in prior year loss reserves, net of related adjustments

Combined ratio excluding catastrophic activity and prior year development

OUR COMPANY

General

reinsurance  and  mortgage 

Arch Capital is a publicly listed Bermuda exempted company 
with  approximately  $15.6  billion  in  capital  at  December  31, 
2022  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  2022,  we  wrote  $11.1  billion  of  net  premiums  and 
reported net income available to Arch common shareholders 
of  $1.4  billion.  Book  value  per  share  was  $32.62  at 
December  31,  2022,  compared  to  $33.56  per  share  at 
December 31, 2021.

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  reinsurance  operations  in  Europe 
began in 2006 in Zurich, Switzerland and with 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  Re  Europe”),  our 
Ireland-based  reinsurance  company  headquartered  in  Ireland 
with  offices  in  Switzerland  and  the  U.K.  The  acquisition  of 
Barbican  in  2019  also  contributed  to  our  reinsurance 
operations.  In  2021,  Arch  Re  Bermuda  completed  the 
acquisition  of  Somerset  Bridge  Group  Limited,  Southern 
Rock  Holdings  Limited  and  affiliates  (“Somerset  Group”). 
The  acquisition

integrated  claims  operation.  See  “Operations—Reinsurance 
Operations” for further details on our reinsurance operations.

Our  mortgage  operations  include  U.S.  and  international 
mortgage  insurance  and  reinsurance  operations,  as  well  as 
participation  in  government  sponsored  enterprise  (“GSE”) 
credit  risk-sharing  transactions.  The  U.S.  mortgage  platform 
was  established  in  2014  and  expanded  greatly  in  2016 
through  the  acquisition  of  United  Guaranty  Corporation 
(“UGC”).  Our  U.S.  primary  mortgage  operations  provide 
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 
and 
along  with  mortgage 
reinsurance  on  a  global  basis.  Our  European  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 and the company 
relinquished  its  APRA  authorization.  See  “Operations—
Mortgage  Operations”  for  further  details  on  our  mortgage 
operations.

is  our  belief 

It 
that  our  underwriting  platform,  our 
experienced  management  team  and  our  strong  capital  base 
have enabled us to establish a strong presence in the markets 
in which we participate.

In  2014,  we  acquired  approximately  11%  of  Somers 
Holdings  Ltd.  (formerly  Watford  Holdings  Ltd.).  Somers 
Holdings  Ltd.  is  the  parent  of  Somers  Re  Ltd.  (formerly 
Watford Re Ltd.), a multi-line Bermuda reinsurance company 
(together with Somers Holdings Ltd., “Somers”). 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

Premia  Holdings  Ltd.,  “Premia”).  In  2021,  the  Company 
completed  the  share  purchase  agreement  with  Natixis,  a 
French  financial  services  firm,  to  purchase  29.5%  of  the 
common  equity  of  Coface  SA  (“Coface”),  a  France-based 
leader  in  the  global  trade  credit  insurance  market.  See 
“Operations—Other  Operations”  for  further  details  on 
Somers, Premia and Coface.

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, 
2022,  Arch  Capital  has  repurchased  433.6  million  common 
shares  for  an  aggregate  purchase  price  of  $5.9  billion.  At 
December  31,  2022,  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 2022 fiscal 
year,  we  repurchased  12,891,405  shares  for  an  aggregate 
amount  of  $585.8  million  under  our  share  repurchase 
program.

OPERATIONS

We classify our businesses into three underwriting segments– 
insurance,  reinsurance  and  mortgage  and  two  operating 
segments–  corporate  and  ‘other.’  For  an  analysis  of  our 
underwriting  results  by  segment,  see  note  4,  “Segment

Arch  Insurance  Canada  Ltd.  (“Arch  Insurance  Canada”),  a 
Canada  domestic  company  which  is  authorized  in  all 
Canadian provinces and territories. Arch Insurance Canada is

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. As 

of  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 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

As part of the Barbican acquisition, we also acquired Castel 
Underwriting  Agencies  Limited  (“Castel”)  in  the  U.K.  and 
Castel Underwriting Europe BV in the Netherlands, giving us 
additional  underwriting  intermediary  capabilities  for  our 
underwriting  platforms.  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. 

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

in  charge  of  each  region 

is  primarily 
executive 
the  marketing  and 
responsible  for  all  aspects  of 
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.

•  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 
group’s  senior  management  closely  monitors 
the 
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  in  stable  and  niche  areas. 
Our insurance group aims to build more integrated long-
term  alignment  with  strategic  partners  offering  superior 
access 
scalable 
to  niche  opportunities,  quality 
businesses, or lines with reliable defensive qualities. 

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.

Philosophy.  Our 

Underwriting 
group’s 
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 

insurance 

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  provided  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  commissions 
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

trends.  Our  reinsurance  group  believes  that  its  existing

Canada,  broad  underwriting  expertise  and  substantial 
capital  facilitate  adjustments  to  its  mix  of  business

the greatest potential for underwriting profitability.

• Maintain  a  low  cost  structure.  Our  reinsurance  group

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

reinsurance 
arrangement (also known as pro rata reinsurance, quota share 
reinsurance or participating reinsurance), the reinsurer shares 
a proportional part of the original premiums and losses of the 
reinsured. The reinsurer pays the cedent a commission which 
is  generally  based  on  the  cedent’s  cost  of  acquiring  the 
business  being  reinsured  (including  commissions,  premium 
taxes, 
administrative 
expenses)  and  may  also  include  a  profit  factor.  Non-
proportional  (or  excess  of  loss)  reinsurance  indemnifies  the 
reinsured  against  all  or  a  specified  portion  of  losses  on 
underlying  insurance  policies  in  excess  of  a  specified 
amount,  which  is  called  a  “retention.”  Non-proportional 
business  is  written  in  layers  and  a  reinsurer  or  group  of 
reinsurers  accepts  a  band  of  coverage  up  to  a  specified 
amount.  The  total  coverage  purchased  by  the  cedent  is 
referred to as a “program.” Any liability exceeding the upper 
limit of the program reverts to the cedent.

treaty  operations  participate 

The  reinsurance  group’s  treaty  operations  generally  seek  to 
write  significant  lines  on  less  commoditized  classes  of 
coverage, such as specialty property and casualty reinsurance 
treaties.  However,  with  respect  to  other  classes  of  coverage,

relatively  large  number  of  treaties  where  they  believe  that 
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 
their 
companies  for 
reinsurance  treaties,  for  unusual  risks  or  for  amounts  in 
excess of the limits on their reinsurance treaties.

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

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

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.

Mortgage Operations

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 to 
insurers  on  both  a  proportional  and  non-

the acquisition of UGC and its primary operating subsidiary,

(“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 
lenders’  mortgage 
insurance.  In  December  2022,  we 
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:

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 
mortgage  insurance  covering  first  lien,  one-to-four 
family residential mortgages. Nearly all of our mortgage 
insurance  written  provides  first  loss  protection  on  loans 
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.

traditional  mortgage 

Other  credit  risk-sharing  products.  In  addition  to 
providing 
and 
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) 
(“Arch  CRS”)  Ltd.  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;

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  7.1%  and 
6.3%  of  our  gross  premiums  written  for  the  years  ending 
December  31,  2022  and  2021,  respectively.  No  other 
customer  accounted  for  greater  than  2.8%  of  the  gross 
premiums  written  for  the  years  ending  December  31,  2022 
and  2021,  respectively.  The  percentage  of  gross  premiums 
written on our top 10 customers was 23.6% and 22.7% as of 
December  31,  2022  and  2021,  respectively.  In  Europe, 
Bermuda and Australia, our products and services are/or will 
be  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 
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. 

include  payment  forbearance, 

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

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

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 
to

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  2017  we  and  Kelso  sponsored  the  formation  of  Premia. 
Premia’s  strategy  is  to  reinsure  or  acquire  companies  or

insurance and reinsurance run-off market. Arch Re Bermuda 
and  certain  Arch  co-investors  invested  $100.0  million  and 
acquired approximately 25% of Premia as well as warrants to 
purchase  additional  common  equity.  Arch  Re  Bermuda  is 
providing  a  25%  quota  share  reinsurance  treaty  on  certain 
business written by Premia, and subsidiaries of Arch Capital 
are  providing  certain  administrative  and  support  services  to

serve on the seven person board of directors of Premia. In the 
2019 fourth quarter, Barbican entered into certain reinsurance 
and  related  transactions  with  Premia  pursuant  to  which 
Premia assumed a transfer of liability for the 2018 and prior 
years of account of Barbican as of July 1, 2019. See note 16,

In  2021,  the  Company  completed  the  share  purchase

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

We  are  driven  by  our  common  purpose  of  “Enabling 
Possibility”  for  our  customers,  our  communities  and  our 
employees.  This  purpose  is  supported  by  our  collaborative, 
results-driven culture which relies on our dedicated, engaged 
and talented people. By offering a meaningful and inclusive 
employee  experience,  we  not  only  help  people  perform  at 
their  best  among  colleagues  who  care,  but  also  support  our 
strategy  of  delivering  specialty  products  and  innovative 
solutions to our customers in each of our business segments. 
As  of  February  1,  2023,  we  had  just  over  5,800  employees 
globally, compared to around 5,200 last year, which directly 
speaks to our ability to grow and retain our talent despite the 
challenges  we  all  faced  with  the  global  pandemic.  We  have 
approximately  3,300  employees  in  North  America  (U.S., 
Canada  and  Bermuda),  1,500  employees  in  Europe  and  the 
U.K.  and  1,000  employees  in  the  Philippines,  Australia  and 
the rest of the world. 

Our People and Culture. In 2022, Arch employees began to 
return  to  offices  globally  as  the  pandemic  eased.  We 
recognize  the  incredible  resiliency  of  the  team  to  work 
remotely  for  over  two  years  while  balancing  that  with  the 
opportunity  to  maximize  in-person  collaboration  across 
departments.  Arch  is  providing  flexibility  in  our  return  to 
office model utilizing specific “office days” for teams as part 
of a hybrid working model.

Through the global pandemic, the spirit of agility that is part 
of our entrepreneurial roots allowed us to transition virtually 
overnight  to  a  home-based  employee  population.  Since  the 
start  of  the  pandemic  we  recognized  and  supported  the

in  our  operations.  In  addition 

An  important  part  of  our  culture  is  building  an  inclusive, 
diverse  workforce.  By  better  reflecting  the  demographics  in 
the markets in which we operate while also actively instilling 
norms  for  inclusive  behavior,  we  leverage  all  the  best 
contributions and thinking across our Company. To that end, 
we  are  committed  to  further  integrating  diversity  and 
inclusion  principles 
to 
“embedding” 
talent  processes,  e.g., 
into  our 
promotion  reviews,  over  500  employees  (mostly  managers) 
have  attended  our  intensive,  six-week  Fostering  Inclusive 
Leadership  program.  Importantly,  this  program  requires 
participants to complete a business-related project as well as 
attend group discussions, where participants focus on how to 
apply inclusive techniques into the work experience. Finally, 
in 2022 our six employee networks provided a forum for over 
1,000  employees  to  share  ideas,  build  community  and 
belonging, provide leadership opportunities for members, and 
contribute  meaningfully  to  business  outcomes.  Importantly, 
our  networks  include  significant  ally  representation,  which 
underscores the inclusive behavior of our people.

Talent  Acquisition,  Development,  Rewards  and  Retention. 
Our  employees  are  our  greatest  asset,  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.  We  continue  to 
enhance  our  talent  acquisition  process  through  a  new  model 
which  will  modernize  our  approach  to  talent  acquisition  for 
candidates and hiring managers, while providing an enhanced 
ability  to  proactively  source  and  build  pipelines  for  the  best 
diverse  talent.  The  model  will  help  streamline  this  process 
across  our  Company  by  using  a  common  platform  and 
approach, which we can easily scale as we grow.

We  provide  unique  career  growth  opportunities  through  a 
combination  of  on-the-job  training,  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 and

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

At  December  31,  2022,  total  investable  assets  held  by  Arch 
were  $28.1  billion.  Our  current  investment  guidelines  and

diversification of risk. Our investments are subject to market-
wide  risks  and  fluctuations,  as  well  as  to  risks  inherent  in 
particular  securities.  While  maintaining  our  emphasis  on 
preservation of capital and liquidity, we expect our portfolio 
to  become  more  diversified  and,  as  a  result,  we  may  in  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  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  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 
allocation, 
planning  process, 
reinsurance  purchasing  strategy  and  reviewed  at  insurance 
business  reviews,  reinsurance  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 
the  following  major  risks:  underwriting

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 
throughout  our  risk  management 
risks  are  embedded 
framework.

(reputational 

relations 

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 change 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 
and certain of its committees hold regular executive sessions 
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.

Integration.  We  believe 

Implementation  and 
that  an 
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 
management 
framework  within  our  decision  making 
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.

We also take the results of the ORSA into account within our 
capital 
system  of  governance,

various  elements  of  our  strategic  decision-making  including 
how  best  to  optimize  capital  management,  establishing  the 
most  appropriate  premium  levels  and  deciding  whether  to 
retain or transfer risks.

REGULATION

General

Our  insurance  and  reinsurance  subsidiaries  are  subject  to 
varying degrees of regulation and supervision in the various 
jurisdictions  in  which  they  operate.  We  are  subject  to 
extensive  regulation  under  applicable  statutes  in  these 
countries  and  any  other  jurisdictions  in  which  we  operate. 
The current material regulations under which we operate are 
described  below.  We  may  become  subject  in  the  future  to 
regulation in new jurisdictions or to additional regulations in 
existing jurisdictions.

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

Table of Contents

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

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  company  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.

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

investments,  methods  of  accounting,  form  and  content  of 
financial  statements,  certain  aspects  of  governance,  ERM, 
amounts  we  are  required  to  hold  as  reserves  for  future 
payments, minimum capital and surplus requirements, annual 
and other report filings and transactions among affiliates. Our 
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.

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 
reinsurance  company  unless 
that  person  has  filed  an 
application  with  specified  information  with  such  company’s 
domiciliary

commissioner’s  prior  approval.  Under  most  states’  statutes

insurance  company  or  its  parent  company  is  presumptively 
considered  an  acquisition  of  control  of  the  insurance 
company, although such presumption may be rebutted. 

State  holding  company  acts  and  regulations  also  impose 
extensive  informational  requirements  on  parents  and  other 
affiliates  of  licensed  insurers  or  reinsurers  with  the  purpose 
of  protecting  them  from  enterprise  risk,  including  requiring 
an  annual  enterprise  risk  report  by  the  ultimate  controlling 
person  identifying  the  material  risks  within  the  insurance 
holding company system that could pose enterprise risk to the 
licensed  companies  and  requiring  a  person  divesting  its

of  an  insurance  holding  company  system  to  file  an  annual 
group  capital  calculation,  unless  the  ultimate  controlling 
person  or  its  insurance  holding  company  system  is  exempt 
from the filing requirement. The group capital calculation is 
designed to assist state insurance regulators in understanding 
the financial condition of non-insurance entities that are part 
of  an  insurance  holding  company  system  and  the  degree  to 
which  insurance  companies  are  supporting  those  non-
insurance entities.

Regulation of Dividends and Other Payments from Insurance 
Subsidiaries.  The  ability  of  an  insurer  to  pay  dividends  or 
make  other  distributions  is  subject  to  insurance  regulatory 
limitations  of  the  insurer’s  state  of  domicile.  Such  laws

disapproval after receiving notice.

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

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  February  23,  2023, 
Arch Re Bermuda is approved as a “certified reinsurer” in 44 
states  with  applications  pending  in  8  additional  states  and 
territories. In addition, 2019 amendments to the NAIC Model 
reinsurance  collateral 
Law  and  Regulation  eliminate 
requirements for reinsurers that (1) have their head office or 
are domiciled in member states of the EU, the U.K. and other 
jurisdictions  deemed  “reciprocal  jurisdictions”  by  the  NAIC 
(although individual states may 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  reciprocal  jurisdictions  includes  Bermuda, 
Japan  and  Switzerland.  All  U.S.  states,  the  District  of 
Columbia  and  Puerto  Rico  have  adopted

Privacy  legislation  and  regulation  has  also  become  an  issue 
of increasing focus in many states. The California Consumer 
Privacy Act of 2018 (“CCPA”), came into effect on January 
1,  2020,  and  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 
2020 (“CPRA”) passed as part of the November 2020 ballot 
and  became  fully  effective  on  January  1,  2023.  The  CPRA 
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 
Protection  Agency  (“CPPA”).  The  CPPA  is  also  currently 
finalizing proposed regulations implementing the CPRA, and

is mandated by the CPRA to adopt additional regulations that 
have yet to be proposed.

guaranty  insurance,  among  other  lines  of  business,  is 
typically exempt from participation in guaranty funds.

A range of new cybersecurity and privacy laws are also under 
consideration  in  other  states,  as  well  as  by  the  federal 
government. The American Data Privacy and Protection Act 
introduced in the U.S. Congress, if enacted, would also apply 
to  our  U.S.  operations.  Several  states,  including  Virginia, 
Colorado,  Connecticut  and  Utah,  have  adopted  new 
comprehensive  data  privacy  legislation  that  is  coming  into 
effect  in  2023.  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.

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  has  established  a  Mortgage 
Guaranty  Insurance  Working  Group  which  is  engaged  in 
developing  changes  to  the  Mortgage  Guaranty  Insurers 
Model  Act,  including  the  development  of  supplemental 
disclosures schedules unique to mortgage guaranty insurers. 

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

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

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  Federal 
Insurance Office (“FIO”) within the Department of Treasury 
(“U.S.  Treasury”),  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 insurance matters, and is authorized to assist the 
U.S.  Secretary  of  the  Treasury  in  negotiating  “covered 
agreements” between the U.S. and foreign governments that 
address insurance prudential measures. In 2022 and 2021, the 
FIO  requested  public  comment  on  insurance  responses  to 
climate-related 
risks  and  catastrophic  cyber 
incidents  affecting  critical  infrastructure.  This  information 
gathering  could  culminate  in  recommendations  for  new 
legislation  to  the  U.S.  Congress.  On  October  18,  2022,  the 
FIO issued a proposed data collection from insurers to assess 
climate  related  financial  risk  across  the  United  States.  See 
“Risk Factors—Risks Relating to Our Industry, Business and 
Operations—We  could  face  unanticipated  losses  from  war, 
terrorism,  cyber  attacks,  pandemics  and  political  instability, 
and these or other unanticipated losses could have a material 
adverse  effect  on  our  financial  condition  and  results  of

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 
Insurer  Eligibility  Requirements 
Private  Mortgage 
(“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,  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,  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.

United Kingdom 

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”).

The  objectives  of  the  PRA  are  to  promote  the  safety  and 
soundness  of  all  firms  it  supervises  and  to  secure  an 
appropriate  degree  of  protection  for  policyholders.  The 
objectives  of  the  FCA  are  to  ensure  customers  receive 
financial  services  and  products  that  meet  their  needs,  to 
promote  sound  financial  systems  and  markets  and  to  ensure 
that  firms  are  stable  and  resilient  with  transparent  pricing 
information  and  which  compete  effectively  and  have  the 
interests of their customers and the integrity of the market at 
the  heart  of  how  they  run  their  business.  The  PRA  has 
responsibility  for  the  prudential  regulation  of  banks  and 
insurers, while the FCA has responsibility for the conduct of 
business  regulation  in  the  wholesale  and  retail  markets.  The

PRA  and  the  FCA  adopt  separate  methods  of  assessing 
regulated  firms  on  a  periodic  basis.  Arch  Insurance  (U.K.)

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, 
as  amended,  has 
transposed  all  applicable  direct  EU 
legislation  into  domestic  U.K.  law,  thus  ensuring  the 
continuing  application  of  Solvency  II  under  the  U.K.’s 
financial services regulatory regime. 

The  U.K.  government  commenced  a  post-Brexit  review  of 
Solvency  II  in  June  2020.  The  response  to  the  review, 
published in early July 2021, suggested that there will likely 
be changes in the U.K. Solvency II framework, including the 
removal of certain prescriptive requirements. In parallel, the 
PRA also undertook a review of Solvency II and, launched a 
quantitative  study  which  contained  both  quantitative  studies 
and qualitative questions intended to guide future reforms of 
Solvency  II  in  the  U.K.  Additionally,  the  U.K.  government 
had  undertaken  a  Future  Regulatory  Framework  Review  to 
determine  how  the  financial  services  regulatory  framework 
should  adapt  to  the  U.K.’s  new  position  outside  of  the  EU. 
On  April  28,  2022,  HM  Treasury  announced  a  third 
consultation  period  for  Solvency  II,  which  will  inform  the 
design  of  the  final  reform  package.  In  HM  Treasury’s 
consultation response, published on November 17, 2022, the 
government  stated  it  will  introduce  a  simpler,  clearer  and 
more tailored regime. Significant changes to be introduced by 
these reforms include the proposal to reduce the risk margin 
component  of  the  solvency  capital  calculation  by  30%  for 
general insurers and remove branch capital requirements.

In  January  2022,  the  U.K.  Parliament,  via  its  Industry  and 
Regulators  Committee  (the  “Committee”),  launched  an 
inquiry into the U.K. insurance and reinsurance industry and, 
specifically,  into  the  regulation  of  the  London  market,  the 
U.K.’s market for commercial and wholesale specialty risks. 
The inquiry reviewed the extent to which regulatory policy is 
well-designed  and  proportionately  applied,  the  possibilities 
for  optimizing  policy  following  Brexit,  the  roles  of  the 
current  U.K.  regulators,  such  as  the  FCA  and  the  Bank  of 
England,  as  well  as  the  appropriateness  of  regulation. 
Following  its  enquiry,  the  Committee  outlined  industry

concerns regarding a perceived lack of proportionality in the 
regulation  of  the  London  Market  by  the  PRA  and  FCA, 
which  was  described  as  overly  burdensome  and  demanding. 
The  Committee  explained  industry  concerns  that  an  overly 
inflexible culture within the regulators may inhibit new forms 
of  business  within  the  U.K.’s  commercial  (re)insurance 
industry. The result of these reviews by the U.K. government 
may have an impact on whether the U.K. is granted Solvency 
II  equivalence  status  by  the  EU  in  any  of  the  three  areas  to 
which equivalence applies.

control  over  any  regulated  company,

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 
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.), AMAL 
or Castel, 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 
from  Arch

Insurance  (U.K.)  to  Arch  Insurance  (EU)  was  completed 
under Part VII of the U.K. Financial Services and Market Act 
2000 at the end of December 2020 (“Part VII Transfer”).

Despite  the  loss  of  passporting  rights,  AMAL,  Syndicate 
2012 and Syndicate 1955 are still able to write business in the 
EEA  via  the  Lloyd’s  Insurance  Company,  S.A.  (“Lloyd’s 
Brussels”). Lloyd’s has been in discussions with the Belgium 
Financial  Services  Markets  Authority  (“Belgium  FSMA”) 
and  the  National  Bank  of  Belgium  regarding  the  Lloyd’s 
Brussels operating model. In January 2021, Lloyd’s released 
a communication stating that its discussions with supervisors 
had  focused  on  certain  risk  placement  services  for  open 
market  business  which  was  being  performed  by  managing 
agents on behalf of Lloyd’s Brussels. Lloyd’s Brussels is in 
an ongoing dialogue with the Belgium FSMA in its effort to 
overhaul  its  initial  underwriting  structures  and  is  deploying 
significant  efforts  and  investment  to  adjust  its  operating 
model  to  satisfy  the  Belgian  authority  in  the  post-Brexit 
environment. This may have an impact on the way managing 
agents  and  syndicates  access  and  operate  on  the  Lloyd’s 
platform.  Lloyd’s  Brussels  is  seeking  to  ensure  that  the 
claims  it  pays  and  complaints  it  processes  preserve  the 
objectives  of  policyholder  protection  and  market  discipline 
under the Insurance Distribution Directive. 

The  U.K.  government  established  a  Temporary  Permissions 
Regime  (“TPR”)  which  came  into  force  with  effect  from 
January  1,  2021,  which  allows  EEA  firms  such  as  Arch  Re 
Europe and Arch Insurance (EU), covered by a passport prior 
to  that  date,  who  wish  to  continue  carrying  out  business  in 
the  U.K.  in  the  longer  term,  to  operate  in  the  U.K.  for  a 
limited  period  while  they  seek  authorization  or  recognition 
from  the  U.K.  regulators.  However,  no  TPR-equivalent 
regime  is  in  place  for  U.K.  firms  who  wish  to  continue 
carrying  out  business  in  the  EEA.  In  the  absence  of  a  TPR-
equivalent  regime  for  U.K.  firms,  the  ability  of  U.K.  firms 
(including,  Arch  Insurance  (U.K.),  AMAL  and  Castel)  to 
continue  doing  business  in  the  EEA  depends  on  applicable 
EEA state local law and regulation. Similarly, 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.

The  long-term  implications  of  Brexit  on  the  Solvency  II 
framework  in  the  U.K.  continues  to  remain  uncertain  in 
relation  to  the  arrangements  that  will  allow  U.K.  and  EU-
established firms to continue to effectively transact business 
with each other and how the future relationship between the 
two  parties  will  adversely  affected  regulated  entities.  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.”

On December 24, 2020, the EU and the U.K. agreed the EU-
U.K.  Trade  Cooperation  Agreement  (the  “TCA”)  which 
details the terms of the future cooperation between the U.K. 
and the EU. The TCA was signed by both the EU and U.K. 
on  December  30,  2020  and  entered  into  force  on  May  1, 
2021.  The  TCA  did  not  preserve  the  status  of  financial 
services  and  as  a  result,  under  the  provisions  of  the  TCA, 
EEA  financial  institutions  (including  our  Irish  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  by  U.K.  financial 
institutions  into  the  EU,  the  post-Brexit  status  and  rules 
applicable to U.K. branches of EEA financial institutions will 
be  primarily  driven  by  U.K.  law  and  regulation.  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.”

In February 2022, a U.K.-EU Financial Services inquiry was 
launched  by  the  U.K.  Parliament.  The  European  Affairs 
Committee  (“EA  Committee”)  published  the  report  in  June 
2022, finding that the TCA contains only limited provisions 
relating  to  insurance  and  financial  services  and  raising 
concerns about the lack of a functioning framework for U.K.-
EU  co-operation.  The  report  also  found  an  absence  of  EU 
equivalence  decisions  over  financial  services,  which  will 
determine  how  London  will  fit  into  the  EU  market  post-
Brexit.  Overall,  the  EA  Committee  called  on  the  U.K. 
government 
its  political  and  diplomatic 
engagement with the EU regarding financial services. In June 
2022, 
the 
formation  of  a  subcommittee  to  scrutinize  proposed  post-
Brexit  financial  regulations  in  the  U.K.,  replacing  the  role 
previously  held  by  the  EU.  See  “Risk  Factors—Risks

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 (aligned with 
the  recommendations  of  the  Taskforce  on  Climate-related 
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 a consultation paper 
in  November  2022  on  its  proposed  regime  of  Sustainability 
Disclosure  Requirements  (“SDR”),  which  would  require 
corporate  disclosures,  asset  manager  and  asset  owner 
disclosures,  and  investment  product  disclosures  covering  a 
broader  range  of  sustainability  topics.  The  SDR  rules  are 
expected  to  be  finalized  in  the  first  half  of  2023,  with 
disclosures applying from 2024 and reporting commencing in 
2025.

In  October  2022,  the  Green  Technical  Advisory  Group 
("GTAG")  published  its  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  report  notes  that 
the primary focus of the U.K. Green Taxonomy should be on 
investors and financial market participants and, as many U.K. 
financial  market  participants  will  also  be  subject  to  the  EU 
Taxonomy, the U.K. should ensure close alignment with the 
EU  Taxonomy  so  as  to  limit  divergence  and  market 
fragmentation.  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 
the  risk  of 
greenwashing.

increases 

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  another 
year to decide the U.K.’s approach. In addition, Lloyd’s has 
mandated 
that  managing  agents  must  create  an  ESG 
framework  and  strategy,  for  sign-off  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 
services 
include  prohibitions  on  providing 
(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.

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.

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 
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.

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, 
Arch  Re  Europe,  Arch 
(EU)  and  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, 
to  financial  and  operational 
they  will  remain  subject 
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 
proposed  guidance  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. While this guidance is currently in draft 
format, Arch is closely monitoring its development given the 
potential impact it may have on Arch's Irish entities. See also 
“European Union – ESG Considerations.”

Irish Individual Accountability Framework Bill. The Central 
Bank  (Individual  Accountability  Framework)  Bill  2022  (the 
“Bill”) was published in July 2022 and legislative scrutiny of 
the Bill is ongoing in the Irish parliament. This Bill proposes 
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 
including 
(re)insurance  companies.  The  Bill  is  expected  to  come  into 
effect in late 2023 or early 2024. See also “European Union –

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.

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, subject to similar 
regulatory notifications and there being no objection from the 
CBI  and  the  Member  States  concerned  and,  in  respect  of 
Arch Insurance (EU), insurance services in all EEA states.

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 if 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 

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

includes  specific  measures  providing  for  the  supervision  of 
reinsurance  groups.  However,  as  a 
insurance  and 
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 
supervision,  where  this  results  in  more  efficient  supervision 
of the group and does not impair EEA supervisors in respect 
of their individual responsibilities.

The Insurance Distribution Directive (“IDD”) was published 
in  February  2016.  EEA  Member  States  were  required  to 
transpose  the  IDD  by  October  1,  2018.  It  replaces  the 
existing  Insurance  Mediation  Directive.  The  IDD  applies  to 
insurance  and  reinsurance  products 
all  distributors  of 
(including 
to 
reinsurers  selling  directly 
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  reinsurance  include  more 
specific  conditions  regarding  knowledge  and  continuing 
professional development requirements for those involved in 
distribution of (re)insurance products. The IDD continues the 
existing  ability  for  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.  The  European  General  Data  Protection  Regulation 
(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,  and  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, evidenced 
data controller accountability for compliance with the GDPR 
principles (including fairness and transparency), maintenance 
of data processing activity records and the implementation of 
“privacy  by  design,”  including  through  the  completion  of

In  addition,  the  EU  GDPR  increases  scrutiny  of  transfers  of 
personal  data 
the  European 
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  (“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 
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  and 
the  European  Commission  published  new  versions  of  the 
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  which  will  act  as  a  successor  to  the 
invalidated  EU-U.S.  Privacy  Shield.  If  approved  by  the 
European Commission and implemented, the agreement will 
facilitate  the  transatlantic  flow  of  personal  data  and  provide 
additional 
transfer 
mechanisms  (including  SCCs)  for  companies  transferring 
personal  data  from  the  EU  to  the  U.S.  However,  before 
entities  rely  on  the  new  EU-U.S.  Privacy  Shield,  there  are 
still legislative and regulatory steps that must be undertaken 
both  in  the  U.S.  and  in  the  EU.  Therefore,  at  present  SCCs 
are  still  the  primary  safeguard  available  for  personal  data 
transfers from the EU to the U.S.

safeguards 

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.

Following the end of the Transition Period on December 31, 
2020,  GDPR  was  implemented  in  the  U.K.  (the  “U.K. 
GDPR”)  with  similar  fines  for  non-compliance.  The 
requirements  of  the  U.K.  GDPR  are  virtually  identical  to 
those  of  the  EU  GDPR,  including  the  prohibition  on  the 
transfer of personal data from the U.K. to other countries that 
are not recognized as having “adequate” data protection laws, 
including the U.S., in a similar manner to the EU. Transfers 
of  personal  data  from  the  U.K.  to  the  EEA  are  unrestricted 
and  do  not  require  additional  safeguards.  In  June,  2021  the 
European  Commission  formally  adopted  an  adequacy

decision for the U.K., meaning data can flow freely from the 
EU to the U.K. This adequacy decision will remain in place 
for four years (until June 27, 2025) after which the adequacy 
decision may be renewed if the U.K. continues to ensure an 
adequate  level  of  data  protection.  However,  the  European 
Commission  retains  the  power  to  suspend,  repeal  or  amend

government  has  published  its  own  form  of  SCCs,  known  as 
the  International  Data  Transfer  Agreement  and  International 
Data  Transfer  Addendum  to  the  EU  SCCs.  The  U.K. 
Information  Commissioner’s  Office  has  also  published  its 
version  of  the  transfer  impact  assessment  and  revised 
guidance  on  international  transfers,  although  entities  may 
choose  to  adopt  either  the  EU  or  U.K.  style  transfer  impact 
assessment.  In  terms  of  international  data  transfers  between 
the U.K. and U.S., it is understood that the U.K. and the U.S. 
are negotiating an adequacy agreement.

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 
Insurance  Distribution  Directive,  were  published.  The  EC 
Regulations focus on the integration of sustainability into key 
activities  including  product  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 in 
November 16, 2022 and enters 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,  are 
the  European 
currently  anticipated 
Commission by June 2023.

to  be  adopted  by 

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  currently  required  under  the 
NFRD  (and  subsequently  under  the  CSRD  once  it  is 
implemented).  Certain  of  our  European  entities  will  fall 
within  the  scope  of  certain  reporting  obligations  following 
the implementation of the CSRD.

In  February  2022,  the  European  Commission  adopted  a 
proposal  for  the  Corporate  Sustainability  Due  Diligence 
Directive  (“CSDD”)  and  negotiation  is  ongoing.  While  the 
main focus of this proposal is on conducting due diligence on 
human  rights  and  environmental  impacts  within  a  company 
and  across 
there  are  also  additional 
sustainability  requirements  for  certain  in  scope  entities.  As 
the  CSDD  is  at  an  early  proposal  stage,  its  applicability  to 
certain  of  our  European  entities  is  unclear,  but  we  will 
monitor the development of the CSDD closely.

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 
sanctions on the Russian Federation in response to the crisis 
in  Ukraine.  Given  the  evolving  situation,  we  are  closely 
monitoring  developments  and  the  sanctions  imposed,  to 
ensure our European entities remain in compliance with any 
sanctions measures imposed.

Cyber Risk. Cyber risk and information security is 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.

Swiss  Branch  as  a  branch  office.  As  Arch  Re  Europe  is 
domiciled outside of Switzerland and its activities are limited 
to  reinsurance,  the  Arch  Re  Europe  Swiss  Branch  in 
Switzerland  is  not  required  to  be  licensed  by  the  Swiss 
insurance regulatory authorities.

In August 2014, Arch Underwriters Europe opened a branch 
office in Zurich (“Arch Underwriters Europe Swiss Branch”) 
to  render  reinsurance  advisory  services  to  certain  group 
companies.  Arch  Underwriters  Europe  Swiss  Branch  is 
registered  with  the  commercial  register  of  the  Canton  of 
Zurich. Since its activities are limited to advisory services for 
reinsurance  matters,  the  Arch  Underwriters  Europe  Swiss 
Branch is not required to be licensed by the Swiss insurance 
regulatory authorities.

Taxation of Arch Capital

Bermuda.  Under  current  Bermuda  law,  Arch  Capital  is  not 
subject to tax on income or profits, 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. Given the limited 
duration of the Minister of Finance's assurance, we could be 
subject  to  taxes  in  Bermuda  after  that  date.  This  assurance 
will be subject to the proviso that it is not to be construed so 
as  to  prevent  the  application  of  any  tax  or  duty  to  such 
persons as are ordinarily resident in Bermuda (we are not so 
currently  affected)  or  to  prevent  the  application  of  any  tax 
payable  in  accordance  with  the  provisions  of  the  Land  Tax 
Act 1967 of Bermuda or otherwise payable in relation to any 
property  leased  to  us  or  our  insurance  subsidiary.  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 
the  Bermuda 
government.

to 

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 

regulations 

(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 the 
permanent  establishment  provisions  of  a  tax  treaty.  Such 
income  tax,  if  imposed,  would  be  based  on  effectively 
connected income computed 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 certain other adjustments.

“Treaty”),  Arch  Capital's  Bermuda 

Under  the  income  tax  treaty  between  Bermuda  and  the  U.S. 
(the 
insurance 
subsidiaries  will  be  subject  to  U.S.  income  tax  on  any 
insurance premium income that is effectively connected with 
a  U.S.  trade  or  business  only  if  that  trade  or  business  is 
conducted through a permanent establishment in the U.S. No 
Treasury  Regulations  interpreting  the  Treaty  have  been 
issued. While there can be no assurances, Arch Capital does 
not believe that any of its Bermuda insurance subsidiaries has 
a  permanent  establishment  in  the  U.S.  Such  subsidiaries 
would not be entitled to the benefits of the Treaty if (i) 50% 
or  less  of  Arch  Capital's  shares  were  beneficially  owned, 
directly  or  indirectly,  by  Bermuda  residents  or  U.S.  citizens 
or residents, or (ii) any such subsidiary's income were used in 
substantial  part  to  make  disproportionate  distributions  to,  or 
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

premiums). 

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 will be subject to 
U.K.  corporation  tax  on  their  respective  profits.  The  U.K. 
branches of Arch Re Europe and Arch Insurance (EU) will be 
subject  to  U.K.  corporation  tax  on  the  profits  (both  income 
profits and chargeable gains) attributable to each branch. The 
rate of U.K. corporation tax for the financial year is 19% on 
profits (increasing 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  will  be  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%.

Denmark.  Arch  Re  Denmark,  established  as  a  subsidiary  of 
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 
incorporated  and  tax  resident  companies,  are  subject  to 
Australian corporate tax on its worldwide profits. The current 
rate of Australian corporation tax applicable to such profits is 
30%.

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  does  not  describe  the  U.S. 
federal  income  tax  consequences  that  may  be  relevant  to 
certain  types  of  shareholders,  such  as  banks,  insurance 
companies,  regulated  investment  companies,  real  estate 
investment  trusts,  financial  asset  securitization  investment 
trusts,  dealers  in  securities  or  traders  that  adopt  a  mark-to-
market  method  of  tax  accounting,  tax  exempt  entities, 
expatriates,  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  the  common  shares  or 
preferred  shares  as  part  of  a  hedging  or  conversion 
transaction  or  as  part  of  a  straddle,  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. 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  interpreted  and  does  not  take  into 
account  possible  changes  in  such  tax  laws  or  interpretations 
thereof, which may apply retroactively. This discussion does 
not  include  any  description  of  the  tax  laws  of  any  state  or 
local  governments  within  the  U.S.,  or  of  any  foreign 
government, that may be applicable to our common shares or 
preferred  shares  or  the  shareholders.  Persons  holding  or 
considering an investment in the common shares or preferred 
shares  should  consult  their  own  tax  advisors  concerning  the 
application  of  the  U.S.  federal  tax  laws  to  their  particular 
situations  as  well  as  any  tax  consequences  arising  under  the 
laws of any state, local or foreign taxing jurisdiction prior to 
making such investment.

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 

ARCH CAPITAL

33

2022 FORM 10-K

Table of Contents

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.

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 
termination  of  the  holder's  stock  interest  in  us  or  (3)  is  “not 
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.  The  determination  as 
to  whether  any  of  the  alternative  tests  of  Section  302(b)  of 
the Code is satisfied with respect to a particular holder of the 
preferred shares depends on the facts and circumstances as of 
the time the determination is made.

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.  For  taxable  years  beginning  on  or  before 
December 31, 2017, 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 of our shares or those of our non-U.S. subsidiaries (as 
applicable).  Under  the  Tax  Cuts  Act,  for  taxable  years 
beginning after December 31, 2017, a 10% U.S. Shareholder 
also  includes  any  U.S.  Person  who  is  considered  to  own, 
actually  or  constructively,  10%  or  more  of  the  value  of  our 
shares  or  those  of  our  non-U.S.  subsidiaries  (as  applicable). 
As  a  result,  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.  For 
taxable  years  beginning  after  December  31,  2017,  a  helpful 
limitation, which provides that a U.S. shareholder would not 
be  subject  to  the  current  inclusion  rules  of  Subpart  F  for  a 
taxable  year  unless  the  non-U.S.  corporation  was  a  CFC  for 
an  uninterrupted  period  of  30  days  or  more  during  such 
taxable year, will no longer apply.

Related  Person  Insurance  Income  Rules.  In  general,  with 
respect  to  RPII  (a  limited  category  of  insurance  income,  as 
defined  below),  the  CFC  rules  are  expanded  in  two 
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 
vote  or  value).  Generally,  RPII

(including reinsurance income) of a foreign corporation with 
respect to which the insured is a United States shareholder of 
the  foreign  corporation  or  a  related  person  to  such  a 
shareholder.

insurance 

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 

that  Section  1248  and 

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.

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 
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  not  a  PFIC,  no 
income tax consequences would result. 

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 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 
insurance  business.  The  PFIC  statutory 
involving 
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,  2022  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.

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  the  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.

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.

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  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

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.

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. 

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

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

• 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.

• As  we  continue  to  incorporate  climate  change  in  our 
business  strategy,  we  cannot  be  certain  that  shareholders, 
investors  and  other  influential  environmental  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. 

• Governmental, regulatory and rating actions in response to 
the  COVID-19  pandemic  have  impacted  us,  and  the 
continuation  or  reinstatement  of  such  actions  may 
adversely affect our financial performance.

• We  could  face  unanticipated  losses  from  war,  terrorism, 
cyber attacks, pandemics and political instability, and these 
or other unanticipated losses could have a material adverse 
effect on our financial condition and results of operations.

• 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.

Risks Relating to Financial Markets and Investments

• 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,  including  issues 
relating to the COVID-19 pandemic, 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,  may 
impact  us  or  our  business  partners  and  service  providers, 
causing a disruption in service and operations which would 
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.

• A  downgrade  in  our  ratings  or  our  inability  to  obtain  a 
rating  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  successfully  our  business  strategy, 
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.

• 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 
imbalances, 
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.

• Uncertainty  relating  to  the  determination  of  the  London

Risk Relating to Our Company

Risks Relating to Our Industry, Business and Operations

• 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.

• There  are  regulatory  limitations  on  the  ownership  and 

transfer of our common shares.

• Arch  Capital  is  a  holding  company  and  is  dependent  on 
dividends  and  other  distributions  from  its  operating 
subsidiaries.

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

• Dividends on our preferred shares are non-cumulative.

• Our preferred shares are equity and are subordinate to our 

existing and future indebtedness.

• The  voting  rights  of  holders  of  our  preferred  shares  are 

limited.

Risks Relating to Taxation

• We  and  our  non-U.S.  subsidiaries  may  become  subject  to 
U.S.  federal  income  taxation  and/or  the  U.S.  federal 
income tax liabilities of our U.S. subsidiaries may increase, 
including as a result of changes in tax law.

• The  continuing  implementation  of  the  Tax  Cuts  Act  may 
have a material and adverse impact on our operations and 
financial condition. 

• Proposed  Treasury  Regulations  issued  on  January  24, 
2022,  if  finalized  in  their  current  form,  could  (on 
prospective  basis)  cause  our  U.S.  shareholders  (including 
tax-exempt U.S. shareholders) to be subject to current U.S. 
federal  income  tax  on  the  portion  of  our  earnings 
attributable  to  certain  intercompany  reinsurance  income 
(whether or not such income is distributed).

• We may become subject to taxes in Bermuda after March 
31, 2035, which may have a material adverse effect on our 
results of operations.

• The  impact  of  Bermuda's  letter  of  commitment  to  the 
OECD  to  eliminate  harmful  tax  practices  is  uncertain  and 
could adversely affect our tax status in Bermuda.

• Legislation enacted in Bermuda as to Economic Substance 

may affect our operations. 

• We may become subject to increased taxation in Bermuda 
and other countries as a result of the OECD's plan on “Base 
erosion and profit shifting.” 

• Application of the EU Anti-Tax Avoidance Directives.

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 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.

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

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.

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.  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  may  vary  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.

including 

The  impact  of  the  COVID-19  pandemic,  the  shift  to  a 
COVID-19  endemic  approach  and  related  risks  could 
materially affect our results of operations, financial position 
and/or liquidity. 

The  COVID-19  pandemic  resulted  in  a  global  slowdown  of 
economic  activity  and  disruption  of  normal  business  travel 
and  working  habits.  While  we  are  shifting  to  a  COVID-19 
endemic approach, there is still uncertainty about the impact 
of  COVID-19  variants  in  the  long-term.  The  COVID-19 
pandemic impacted our results of operations and a reversion 
to the COVID-19 restrictions could have a significant effect 
on  our  future  business,  results  of  operations  and  financial 
performance.  We  may  experience  higher  levels  of  loss  and 
claims activity in certain lines of business, and our premiums 
written  and  earned  could  also  be  adversely  affected  by  a 
suppression  of  global  commercial  activity  that  results  in  a 
reduction  in  insurable  assets  and  other  exposure.  The 
pandemic  initially  resulted  in  a  sharp  contraction  in  the 
global economy, tightening liquidity and increasing volatility 
and  uncertainty  in  the  capital  markets.  Coincident  global 
mitigation  responses  stabilized  markets  and  stimulated 
economic  recovery.  During  the  second  quarter  of  2020, 
pandemic-driven  dislocations  had  a  negative  effect  on  the 
performance  of  our 
investment  portfolio,  after  which 
valuations  recovered.  Continued  macroeconomic  volatility 
may  persist  affecting  our  businesses  and  related  market 
opportunities.  Certain  lines  of  our  business  may  require 
additional forms of collateral in the event of a decline in the 
fair  value  of  securities  and  benchmarks  to  which  those 
repayment mechanisms are linked. The impact of an ongoing 
pandemic on the financial markets may also adversely affect 
our ability to fund through public or private equity offerings, 
debt financings, and through other means at acceptable terms.

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  and  wildfires  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.  Additionally,  climate 
change may make modeled outcomes less certain or produce 
new,  non-modeled  risks.  Additionally,  catastrophic  events 
could  result  in  increased  credit  exposure  to  reinsurers  and 
other counterparties we transact business with, declines in the 
value  of  investments  we  hold  and  significant  disruptions  to 
our  physical  infrastructure,  systems  and  operations.  Climate 
change-related  risks  may  also  specifically  adversely  impact 
the value of the securities that we hold. The effects of climate 
change  could  also  lead  to  increased  credit  risk  of  other 
including 
counterparties  we

transact  business  with, 

income, 

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

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

Governments,  regulators,  legislators  and  influential  non-
governmental  organizations  continue  to  focus  on  enacting

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

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.

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 
loss  of 
form  of  oil  shortages, 
confidence  and  general  increase  in  risks  worldwide.  In 
response  to  this  aggression,  the  governments  of  the  U.S., 
U.K.,  EU  and  other  countries  have  implemented  several 
sanctions  programs  relating  to,  among  other  things,  the 
import  and  transportation  of  Russian  oil  and  gas  and  other 
goods  originating  in  Russia.  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. and EU, 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.  As  a  result,  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 in our business 
strategy,  we  cannot  be  certain  that  shareholders,  investors 
and  other  influential  environmental  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.  Our  leadership  and  Board  are  actively 
engaged  in  understanding  the  ever-changing  ESG  landscape 
and  assessing  our  business  operations  to  ensure  that  our 
business strategy reflects our values, 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

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 and decide 
to  sell  or  not  purchase  our  equity  or  debt  instruments  or  to 
publicize their dissatisfaction.

Actions of the federal, state and local government in the U.S. 
and  other  countries  where  we  do  business,  to  address  and 
mitigate the impact of COVID-19 impacted us. While many 
of those actions have expired, been repealed or removed, it is 
difficult  to  predict  whether  such  legislative  bodies  may 
choose to reintroduce legislation relating to the pandemic or 
continue to update existing regulations. For example, we are 
potentially subject to legislative and/or regulatory action that 
seeks to retroactively mandate coverage for losses which our 
insurance  policies  were  not  designed  or  priced  to  cover. 
There  is  proposed  legislation  in  some  states  to  require

cancel  policies,  our  ability  to  increase  rates  or  our  right  to 
collect premiums. Some state regulators have issued orders to 
review  insurers’  rates  and  prevent  rate  increases,  and 
regulators in other states could take similar actions. It is also 
possible that changes in economic conditions and steps taken 
by  federal,  state  and  local  governments  in  response  to 
COVID-19  could  require  an  increase  in  taxes  at  the  federal, 
state  and  local  levels,  which  would  adversely  impact  our 
results of operations. 

time 

Mortgage defaults related to the pandemic, if not cured, could 
remain in our defaulted loan inventory for a protracted period 
to  forbearance  programs  and 
of 
including  due 
foreclosure  moratoria,  potentially 
in  higher 
resulting 
frequency (claim rate) and severity (amount of the claim) for 
those  loans  that  ultimately  result  in  a  claim.  Accordingly, 
extended  or  extensive  forbearance  programs,  foreclosure 
moratoria  and  other  changes  in  regulations  or  laws  may 
adversely impact our mortgage insurance operations.

In  addition,  the  rating  agencies  continually  review  the 
financial  strength  ratings  assigned  to  the  Company  and  its 
subsidiaries,  and  the  ratings  are  subject  to  change.  The 
COVID-19 pandemic and its impact on financial results and 
condition, could cause one or more of the rating agencies to 
downgrade  the  ratings  assigned  to  the  Company  and  its 
subsidiaries. The pandemic has resulted, and may continue to 
result, in a material increase in new defaults as borrowers fail 
to make timely payments on their mortgages, including as a 
result  of  increases  in  unemployment  and  entering  mortgage 
forbearance programs that allow borrowers to defer mortgage 
payments, which may have an adverse impact on our results 
or operations. 

We  could  face  unanticipated  losses  from  war,  terrorism, 
cyber  attacks,  pandemics  and  political  instability,  and  these 
or other unanticipated losses could have a material adverse 
effect on our financial condition and results of operations.

We  have  substantial  exposure  to  unexpected,  large  losses 
resulting from future man-made catastrophic events, such as 
acts  of  war,  acts  of  terrorism,  pandemics  similar  to  the 
COVID-19  pandemic,  political  instability  and  social  unrest. 
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.  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 2022 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.

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

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

lags  between 

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.

the  reserve  estimates  reflected 

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 
income in the period when the deficiency becomes known. It 
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,  2022,  our  consolidated  reserves  for 
unpaid  losses  and  loss  adjustment  expenses,  net  of  unpaid 
losses  and  loss  adjustment  expenses  recoverable,  were 
approximately  $13.8  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 
and  have  also  considered  available  historical 
industry 
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, 2022.

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 
adverse  effect  on  our  financial  condition  or  our  results  of 
operations,  possibly 
the  extent  of  eliminating  our 
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.

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

in material losses or damage to 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

companies,  including  Arch  Insurance  (U.K.),  to  test  how 
certain  business  interruption  insurance  policies  respond  to

claims  arising  from  COVID-19.  The  High  Court 
September  2020  handed  down  its  judgment  which,  found  in 
favor  of  policyholders  on  the  majority  of  the  key  coverage 
issues  in  the  representative  sample  of  policies  submitted  by 
the defendants. Appeals were filed by six insurers, including 
Arch  Insurance  (U.K.),  and  in  January  2021,  the  Supreme 
Court in the U.K. broadly confirmed the High Court’s rulings 
on  the  business  wordings.  The  impact  of  this  case  on  Arch 
Insurance (U.K.)’s results of operations has been modest, and 
no further litigation has flowed from it that has significantly 
impacted  Arch  Insurance  (U.K.).  Whilst  the  judgment 
amended  the  law  in  some  respects  (namely  the  tests  for 
causation  in  English  litigation),  to  date  this  has  not  had  a 
significant impact on Arch Insurance (U.K.) claims and it is 
not  anticipated  to  do  so,  however  this  cannot  be  ruled  out 
entirely.  See  “Risks  Relating  to  Our  Mortgage  Operations” 
for further details on our mortgage operations.

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 
operational 
reporting  systems;  establishing  satisfactory 
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 
foreign  currency  exchange  rate  fluctuation.  We  may  also  be 

subject to financial exposures in the event that the sellers of 
the entities or business we acquire are unable or unwilling to 
meet their indemnification, reinsurance and other contractual 
obligations  to  us.  Our  failure  to  manage  successfully  any  of 
the foregoing challenges and risks may adversely impact our

for  our  operating  insurance  and  reinsurance  subsidiaries 
may  adversely  affect  our  relationships  with  clients  and 
brokers and negatively impact sales of our products.

Similar  to  our  competitors,  a  ratings  downgrade  or  the 
potential  for  such  a  downgrade,  or  failure  to  obtain  a 
necessary rating, could adversely affect our relationships with 
agents, brokers, wholesalers, intermediaries, clients and other 
distributors  of  our  existing  and  new  products  and  services. 
Some  of  the  reinsurance  agreements  assumed  by  our 
reinsurance  operations  include  provisions  that  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,  provide  our 
ceding company clients certain rights, including, the right to 
terminate the subject reinsurance agreement and/or to require 
us  to  post  additional  collateral.  Any  ratings  downgrade  or 
failure to obtain a necessary rating could adversely affect our 
ability to compete in our markets, could cause our premiums 
and  earnings  to  decrease  and  could  have  a  material  adverse 
impact on our financial condition and results of operations. In 
some  cases,  a  downgrade  in  ratings  of  certain  of  our 
operating  subsidiaries  may  constitute  an  event  of  default 
under our credit facilities.

We  can  offer  no  assurances  that  our  ratings  will  remain  at 
their current levels or that any of our ratings which are under 
review or watch by ratings agencies will remain unchanged. 
It is possible that rating agencies may modify their evaluation 
criteria,  heighten  the  level  of  scrutiny  they  apply  when 
analyzing  companies  in  our  industry,  adjust  upward  the 
capital and other requirements employed in their models and/
or discontinue credit and debt instruments or other structures 
deployed  for  maintenance  of  certain  rating  levels.  We  may 
need  to  raise  additional  funds  through  equity  or  debt 
financings.  Any  equity  or  debt  financing,  if  available  at  all, 
may be on terms that are unfavorable to us. Equity financings 
could be dilutive to our existing shareholders and could result 
in the issuance of securities that have rights, preferences and 
privileges  that  are  senior  to  those  of  our  outstanding 
securities.  If  we  are  not  able  to  obtain  adequate  capital,  our 
business,  results  of  operations  and  financial  condition  could 
be adversely affected. See “Capital Resources” in Item 7 for 
further details.

and  Revolving  Credit  Facilities 

Our  ability  to  execute  successfully  our  business  strategy, 
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.

in  some  cases,  also 

With  the  easing  of  restrictions  relating  to  the  COVID-19 
pandemic, we have adopted a hybrid work model in most of 
our offices with employees returning to the office for part of 
the  work  week.  The  pandemic  impacted  employee  work 
impacted  employee 
models  and, 
workloads  and  attitudes  about  work.  We  provide  a  work 
environment  and  culture  which  reflects  our  goal  to  “Enable 
Possibility”.  We  offer  flexible  work  arrangements,  when 
possible,  for  our  employees  globally,  as  well  as  competitive 
compensation  packages  which  include  participation  in  our 
Employee  Stock  Purchase  Plan  and  the  possibility  of  equity 
awards at certain job levels. Over the past few years, we have 
also  implemented  and  expanded  our  learning  programs, 
career  leveling  and  employee  networks,  all  of  which  we 
believe  will  help  us  retain  talent.  Our  leadership  and  Board 
promote the goals of building a diverse employee population 
and fostering an environment that allows us to fully leverage 
and  engage  that  diversity  as  a  competitive  edge  which 
benefits  both  our  employees  and  our  business.  While  our 
efforts  to  attract,  develop  and  retain  talented  employees 
continues  to  be  a  top  priority,  current  job  market  conditions 
present  challenges  for  us  and  may  adversely  impact  our 
ability to fully realize our business strategy.

Our  success  will  depend  on  our  ability  to  maintain  and 
enhance effective operating procedures and internal controls 
and our ERM program.

We operate within an ERM framework designed to identify, 
assess  and  monitor  our  risks.  We  consider  underwriting, 
reserving, investment, credit and operational risk in our ERM 
framework. Losses, reputational damage, regulatory fines and 
litigation  are  among  the  adverse  impacts  which  can  arise  if 
we fail to operate an effective ERM framework. Operational 
risk  and  losses  can  result  from,  among  other  things,  fraud, 
errors, failure to document transactions properly or to obtain 
to  comply  with 
proper 
regulatory 
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 

internal  authorization,  failure 
information 

requirements,

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 sanction 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 
reinsurers  no  longer  have  automatic  access  to  EU  markets 
and vice versa. Our U.K. domiciled entities and our Lloyd’s 
Syndicates  may  no  longer  “passport”  within  the  EU  and  are 
now  part  of  the  U.K.  temporary  permissions  regime  which 
allows firms to operate in the U.K. for a limited period while 
they  seek  authorization  from  the  U.K.  regulators.  We  have 
implemented  changes  in  our  operations  to  accommodate 
Brexit;  however  we  remain  subject  to  new  proposals  and 
regulations  which  may  negatively  impact  U.K.  underwriting 
activities in respect of EU risks and policyholders.

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, among other factors, has increased uncertainty levels 
and  heightened  volatility  in  the  capital  and  credit  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. More specifically, economic 
conditions  could  also  have  a  material  impact  on  the 
frequency  and  severity  of  claims  and  therefore  could 
negatively  impact  our  underwriting  returns.  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.  The  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  the  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 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. In addition, a lack of pricing transparency, decreased 
market  liquidity,  the  strengthening  or  weakening  of  foreign 
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 
(72.1%  as  of  December  31,  2022).  Although  our  current 
investment  guidelines  and  approach  stress  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 
securities  or 
types  of  securities,  as  well  as  sector 
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.

Uncertainty  relating  to  the  determination  of  LIBOR  and  the 
phasing  out  and  replacement  of  LIBOR  with  alternative 
benchmark rates may adversely impact us.

instruments  denominated 

In order to mitigate the potential adverse effects on our cost 
of capital caused by the uncertainty of the timing and impact 
of  the  phase-out  of  LIBOR,  we  entered  into  certain 
amendments to our credit facilities in 2021 in order to replace 
the  LIBOR-based  benchmarks  for  borrowings  and  letters  of 
credit denominated in British Pounds Sterling and Euros with 
the  Sterling  Overnight  Index  Average  (“SONIA”)  and  the 
Euro Inter-bank Offered Rate (“EURIBOR”), respectively, as 
SONIA and EURIBOR have emerged as preferred alternative 
benchmarks  with  respect  to  certain  indebtedness  and  other 
financial 
these  currencies. 
Similarly,  in  April  2022,  we  entered  into  an  amendment  to 
our  credit  facilities  in  order  to  replace  the  LIBOR-based 
benchmark for borrowings and letters of credit denominated 
in  U.S.  Dollars  with  a  rate  based  on  Secured  Overnight 
Financing  Rate  (“SOFR”).  However,  there  can  be  no 
assurance that these mitigation efforts will adequately protect 
against increases or volatility in our cost of capital. Although 
we  believe  we  have  taken  appropriate  measures  to  adjust  to 
the  replacement  of  LIBOR,  the  transition  from  LIBOR  to 
SOFR  and  other  alternative  reference  rates  may  adversely 
impact  our  investment  portfolio,  our  cost  of  capital  and  our 
cost  of  issuing  Bellemeade  mortgage  risk  transfer  securities 
and  could  require  changes  to  our  current  asset  liability 
strategies.

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  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  the  Arch  MI  U.S.  mortgage 
insurance portfolio remains uncertain.

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 on such a 
loan 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  Arch  MI  U.S.’s  business  could  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. 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.  Further,  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.  The 
premiums  charged,  and  the  associated  investment  income, 
may not be adequate to compensate us for the risks and costs 
to 
associated  with 
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 Arch MI U.S.’s results 
of operations and financial condition. 

insurance  coverage  provided 

the 

including,  among  others,  changes 

The  frequency  and  severity  of  claims  we  incur  is  uncertain 
and will depend largely on general economic factors outside 
in 
of  our  control, 
unemployment,  home  prices  and  interest  rates  in  the  U.S. 
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. Deteriorating economic conditions in 
the U.S., potentially due to prolonged recessionary conditions 
increasing  levels  of  unemployment  and  inflation,  could 
adversely  affect  the  performance  of  our  U.S.  mortgage 
insurance  portfolio  and  could  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”). 
Future changes to the FHA program, including any reduction 
to  mortgage  insurance  premiums  charged  may  negatively 
impact  the  amount  of  mortgage  insurance  we  write  in  the 
U.S. 

(“FHFA”)  as 
The  Federal  Housing  Finance  Agency 
conservator  of  the  GSEs  continues  to  evaluate  loan  level 
price  adjustments  (“LLPAs”)  assessed  by  the  GSEs  when 
purchasing loans. Effective on April 1, 2022, Fannie Mae and 
Freddie  Mac  increased  upfront  fees  for  “high-balance 
loans” (mortgages in excess of $647,000) and mortgages on 
second homes. On October 24, 2022, FHFA announced that 
the  GSEs  are  eliminating  upfront  fees  for  certain  first-time 
low-income  borrowers,  and  underserved 
homebuyers, 
communities  and  is  increasing  fees  for  cash  out  refinance 
loans.  On  January  19,  2023,  FHFA  announced  three  new 
pricing grids that broadly adjusted pricing to GSE purchases. 
These, and future actions 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  groups  to  address  special  social  needs  that 
exist  today.  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  implemented  under  the  GSEs’  Equitable  Housing 
Plans,  may  impact  the  underwriting  and  servicing  standards 
on mortgages purchased by the GSEs and could increase 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 
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.  Any  such  changes  that  come  to  pass  could  have  a 
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,  which  generally  include  only  the 
most  liquid  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,  2022.  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 Capital Rule 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 IV.” The Basel 
Committee expects the new rules to be fully implemented by 
January  2027.  On  September  9,  2022,  the  Federal  banking 
agencies issued a statement reaffirming their commitment to 
implementing the 2017 revisions and stated that a request for 
public  comment  on  new  regulatory  standards  would  be 
forthcoming.  Under  the  Basel  IV  protocols,  banks  using  the 
standardized  approach  for  credit  risk  management  will 
determine the risk-weight for residential mortgages based on 
the 
loan  origination,  without 
consideration  of  mortgage  insurance.  The  U.S.  regulatory 
agencies  could  determine 
that  current  U.S.  rules  for 
residential  mortgages  are  “at  least  as  stringent”  as  the  Basel 
IV  provisions,  and  therefore  do  not  need  to  be  modified. 
However,  if  U.S.  regulators  decide  to  adopt  the  Basel  IV 
approach  to  mortgage  assets,  the  capital  relief  benefits  of 
mortgage  insurance  would  be  diminished,  which  could 
adversely affect the demand for mortgage insurance.

ratio  at 

for  Fannie  Mae  and  Freddie  Mac 

On  December  17,  2020,  the  FHFA  published  a  new  capital 
framework 
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. The rule also imposes a risk-weight floor of 
10 percent on retained CRT positions. In a 2022 amendment, 

ARCH CAPITAL

52

Table of Contents

the  risk-weight  floor  was  reduced  to  5  percent,  and  other 
changes were made to incentivize CRT transactions.

The  new  framework  continues  to  take  into  account  the 
benefits  of  mortgage  insurance,  provided  the  mortgage 
insurer is compliant with the PMIERs. The amount of capital 
relief  afforded  for  mortgage  insurers  will  depend  on  a 
number of factors, including the GSEs’ determination of the 
creditworthiness  of  the  mortgage  insurer.  It  is  possible  that 
the higher capital standards imposed on the GSEs will result 
in increased fees for homebuyers that will reduce the demand 
for  mortgage  loans,  and  therefore  the  demand  for  mortgage 
insurance.  Further,  the  GSEs  will  independently  determine 
the  creditworthiness  of  mortgage  insurance  counterparties, 
which  could  affect  the  competitive  position  of  individual 
mortgage  insurance  providers.  Moreover,  the  higher  risk-
capital  charges 
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.

for 

On January 4, 2023, the unified regulatory agenda issued by 
the Office of Management and Budget referenced that FHFA 
targets  February  2023  for  a  notice  of  proposed  rulemaking 
addressing  capital  requirements  for  derivatives;  market  risk; 
multifamily  loans  in  general  and  multifamily  loans  with 
government  subsidies  specifically,  and  exposures  of  an 
Enterprise to the other Enterprise. There is a risk that future 
changes  to  the  capital  framework  could  adversely  impact 
credit for credit risk transfer or the capital relief afforded 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 
generally at an election of directors. Arch Capital will assume 
that  all  shareholders  (other  than  specified  persons)  are  U.S. 
persons  unless  we  receive  assurance  satisfactory  to  us  that 
they are not U.S. persons.

The bye-laws also provide that the affirmative vote of at least 
66  2/3%  of  the  outstanding  voting  power  of  our  shares 
(excluding  shares  owned  by  any  person  (and  such  person’s 
affiliates and associates) that is the owner of 15% or more (a 
“15%  Holder”)  of  our  outstanding  voting  shares)  shall  be 
required  for  various  corporate  actions,  including:  merger  or 
consolidation of the company into a 15% Holder; sale of any 
or  all  of  our  assets  to  a  15%  Holder;  the  issuance  of  voting 
securities

provisions;  provided,  however,  the  super  majority  vote  will 
not apply to any transaction approved by the Board.

The  provisions  described  above  may  have  the  effect  of 
making  more  difficult  or  discouraging  unsolicited  takeover 
bids from third parties. To the extent that these effects occur, 
shareholders  could  be  deprived  of  opportunities  to  realize 
takeover  premiums  for  their  shares  and  the  market  price  of 
their shares could be depressed. In addition, these provisions

There  are  regulatory  limitations  on  the  ownership  and

The jurisdictions where we operate have laws and regulations 
that require regulatory approval of a change in control of an 
insurer  or  an  insurer's  holding  company.  Where  such  laws 
apply  to  us,  there  can  be  no  effective  change  in  our  control 
unless  the  person  seeking  to  acquire  control  has  filed  a 
statement with the regulators and obtained prior approval for 
the proposed change. Certain regulators may at any time, by 
written notice, object to a person holding shares in an insurer 
or an insurer's holding company if it appears to the regulator 
that the person is not or is no longer fit and proper to be such 
a holder. The regulator may require the shareholder to reduce 
its holding in the insurer or an insurer's holding company and 
direct,  among  other  things,  that  such  shareholder’s  voting 
rights  attaching  to  the  shares  in  an  insurer  or  an  insurer's

from 

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 
any  payments  of  dividends, 
redemption  amounts  or 
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 
subsidiaries to pay dividends or make distributions is subject 
to  legislative  constraints  and  dependent  on  their  ability  to 
meet applicable regulatory standards. In addition, the ability 
to  pay 
insurance  and  reinsurance  subsidiaries 
of  our 
dividends  to  Arch  Capital  and  to  intermediate  parent 
companies  owned  by  Arch  Capital  could  be  constrained  by 
our  dependence  on 
from 
financial 
independent rating agencies. Our ratings from these agencies

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 
limited to:

•

•

•

•

•

whether  dividends  have  been  declared  and  are  likely  to 
be  declared  on  any  series  of  our  preferred  shares  from 
time to time;

our  creditworthiness,  financial  condition,  performance 
and prospects;

whether the ratings on any series of our preferred shares 
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.

Risks Relating to Taxation

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 
restrict  payments  of  dividends  on  our  preferred  shares. 
Additionally,  unlike 
indebtedness,  where  principal  and 
interest would customarily be payable on specified due dates, 
in the case of preferred shares, (1) dividends are payable only 
if declared by the Board (or a duly authorized committee of 
the Board) and (2) as described under “Risks Relating to Our 
Company—Arch  Capital  is  a  holding  company  and  is 
dependent  on  dividends  and  other  distributions  from  its 
operating  subsidiaries,”  we  are  subject  to  certain  regulatory 
and  other  constraints  affecting  our  ability  to  pay  dividends 
and make other payments.

We may issue additional securities that rank equally with or 
senior  to  our  series  F  and  series  G  preferred  shares  without 
limitation. The issuance of securities ranking equally with or 
senior  to  our  preferred  shares  may  reduce  the  amount 
available  for  dividends  and  the  amount  recoverable  by 
holders  of  such  series  in  the  event  of  a  liquidation, 
dissolution or winding-up of Arch Capital.

The  voting  rights  of  holders  of  our  preferred  shares  are 
limited.

Holders  of  our  preferred  shares  have  no  voting  rights  with 
respect  to  matters  that  generally  require  the  approval  of 
voting  shareholders.  The  limited  voting  rights  of  holders  of 
our  preferred  shares  include  the  right  to  vote  as  a  class  on 
certain  fundamental  matters  that  affect  the  preference  or 
special  rights  of  our  preferred  shares  as  set  forth  in  the 
certificate of designations relating to each series of preferred 
shares.  In  addition,  if  dividends  on  our  series  F  or  series  G 
preferred  shares  have  not  been  declared  or  paid  for  the 
equivalent  of  six  dividend  payments,  whether  or  not  for 
consecutive  dividend  periods,  holders  of  the  outstanding 
series  F  or  series  G  preferred  shares  will  be  entitled  to  vote 
for  the  election  of  two  additional  directors  to  the  Board 
subject  to  the  terms  and  to  the  limited  extent  as  set  forth  in 
the  certificate  of  designations  relating  to  such  series  of 
preferred shares.

Arch  Capital  and  its  non-U.S.  subsidiaries  intend  to  operate 
their  business  in  a  manner  that  will  not  cause  them  to  be 
treated as engaged in a trade or business in the U.S. and, thus, 
will not be required to pay U.S. federal income taxes (other 
than  U.S.  excise 
insurance  and  reinsurance 
premiums  and  withholding  taxes  on  certain  U.S.  source 
investment income) on their income. However, because there 
is  uncertainty  as  to  the  activities  which  constitute  being 
engaged  in  a  trade  or  business  in  the  U.S.,  there  can  be  no 
assurance  that  the  IRS  will  not  contend  successfully  that 
Arch  Capital  or  its  non-U.S.  subsidiaries  are  engaged  in  a 
trade or business in the U.S., in which case our shareholders' 
equity and earnings could be adversely affected.

Congress  has  been  considering  several  legislative  proposals 
intended  to  eliminate  certain  perceived  tax  advantages  of 
Bermuda  and  other  non-U.S.  jurisdictions.  There  is  no 
assurance  that  any  such  legislative  proposal  will  not  be 
enacted  into  law  or  that  any  such  enacted  law  would  not 
materially increase our income tax liabilities or those of our 
subsidiaries.

The continuing implementation of the Tax Cuts Act may have 
a  material  and  adverse  impact  on  our  operations  and 
financial condition. 

Certain provisions in the Tax Cuts Act could have a material 
and  adverse  impact  on  our  financial  condition  and  business 
operation. One such provision 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  (including  reinsurance  premiums). 
Other  provisions  of  the  Tax  Cuts  Act  that  could  have  a 
material  and  adverse  impact  on  us  include  a  provision  that 
defers or disallows a U.S. corporation’s deduction of interest 
expense  to  the  extent  such  interest  expense  exceeds  a 
specified  percentage  of  such  U.S.  corporation’s  “adjusted 
taxable  income”  and  a  provision  that  adjusts  the  manner  in 
which  a  U.S.  property  and  casualty  insurance  company 
computes its loss reserve. 

In addition, there is no assurance that subsequent changes in 
tax  laws  or  regulations  will  not  materially  and  adversely 
affect our operations and financial condition.

Proposed Treasury Regulations issued on January 24, 2022, 
if finalized in their current form, could (on prospective basis) 
cause  our  U.S.  shareholders  (including  tax-exempt  U.S. 
shareholders) to be subject to current U.S. federal income tax 
on  the  portion  of  our  earnings  attributable  to  certain 
intercompany  reinsurance  income  (whether  or  not  such 
income is distributed).

Unless an exception applies, U.S. shareholders generally are 
required to include currently in income a portion of any RPII 
recognized  by  our  foreign  subsidiaries,  whether  or  not 
distributed.  Generally,  RPII  is  insurance  income  (including 
reinsurance income) of a foreign corporation with respect to 
which  the  insured  is  a  United  States  shareholder  of  the 
foreign corporation or a related person to such a shareholder.

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  currently  include  RPII  in 
income (although there can be no assurance that this is or will 
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)  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) 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.  shareholders  should  consult  their  own  tax 
advisors as to the potential impact of these recently proposed 
Treasury Regulations.

We may become subject to taxes in Bermuda after March 31, 
2035,  which  may  have  a  material  adverse  effect  on  our 
results of operations.

Under  current  Bermuda  law,  we  are  not  subject  to  tax  on 
income,  profits,  withholding,  capital  gains  or  capital 
transfers.  Furthermore,  we  have  obtained  from  the  Minister 
of  Finance  of  Bermuda  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  tax,  then  the  imposition  of  the  tax  will  not  be 

applicable  to  us  or  our  operations  until  March  31,  2035. 
Given  the  limited  duration  of  the  Minister  of  Finance's 
assurance we cannot be certain that we will not be subject to 
any Bermuda tax after that date, which may have a material 
adverse  effect  on  our  results  of  operations.  This  assurance 
does  not,  however,  prevent  the  imposition  of  taxes  on  any 
person  ordinarily  resident  in  Bermuda  or  any  company  in 
respect of its ownership of real property or leasehold interests 
in Bermuda.

OECD has published reports and launched a global initiative

came into force on January 1, 2019, 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  ES  Act  may  require 
in-scope  Bermuda  entities  which  are  engaged  in  such 
“relevant activities” to be directed and managed in Bermuda, 
have  an  adequate  level  of  qualified  employees  in  Bermuda, 
incur  an  adequate  level  of  annual  expenditure  in  Bermuda, 
maintain  physical  offices  and  premises  in  Bermuda  or 
perform  core  income-generating  activities  in  Bermuda.  The 
list  of  “relevant  activities”  includes  carrying  on  any  one  or 
more  of  the  following  activities:  banking,  insurance,  fund 
leasing,  headquarters,  shipping, 
management,  financing, 
distribution  and  service  center,  intellectual  property  and 
holding entities. An in-scope Bermuda entity that carries on a 
relevant  activity  is  obliged  under  the  ES  Act  to  file  a 
declaration with the Bermuda Registrar of Companies on an 
annual basis containing certain information. Any entity found 
to  be  lacking  adequate  economic  substance  may  be  fined  or 
ordered  by  a  court  to  take  action  to  remedy  such  failure  (or

face  being  struck  off  the  companies  register).  As  a  result, 
there  is  a  risk  that  non-compliance  with  its  economic 
substance requirements under the ES Act could require Arch 
to enhance its infrastructure in Bermuda, and this may result 
in  some  additional  operational  expenditures,  increased  tax 
liabilities and/or compliance costs for Arch.

We  may  become  subject  to  increased  taxation  in  Bermuda 
and other countries as a result 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 
from 
in 

local  customer  markets.  However,  profits 

“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  entities  in  low  tax  jurisdictions  by  introducing  a  global 
minimum  tax  (15%)  and  a  proposed  tax  on  base  eroding 
payments,  which  would  operate  through  a  denial  of  a 
deduction  or  imposition  of  source-based  taxation  (including 
withholding tax) on certain payments. 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 
the 
Implementation  Package  and  related  topics  is  expected  in 
early  2023.  The  OECD  expects  the  rules  to  be  enacted  into 
domestic  legislation  in  2023  in  order  for  the  rules  to  be 
effective  from  2023  (with  a  key  element  of  the  rules,  the 
UTPR, deferred for one year until 2025). 

in  March  2022.  Further  details  of 

On  December  15,  2022,  the  EU  formally  adopted  Council 
Directive on ensuring a global minimum level of taxation for 
groups operating in the Union. Member States are required to 
transpose the Directive into their domestic law by December 
31,  2023.The  OECD  expects  the  rules  to  be  enacted  into 
domestic  legislation  in  2023  in  order  for  the  rules  to  be 
effective  from  2023  (with  a  key  element  of  the  rules,  the 
UTPR,  deferred  for  one  year  until  2025).  The  adoption  of 
these rules may increase the complexity and costs associated 
with  tax  compliance  and  may  adversely  affect  our  financial 
position and results of operations.

Application of the EU Anti-Tax Avoidance Directives

As part of the BEPS project, the EU Council adopted on 12 
July 2016 Council Directive (EU) 2016/1164 (“ATAD I”), as 
amended  by  Council  Directive  (EU)  2017/952  (“ATAD  II”, 
together  with  ATAD  I,  “ATAD”),  to  provide  for  minimum 
standards  across  EU  Member  States  for  tackling  aggressive 
tax  planning  involving  hybrid  tax  mismatches  and  interest 
deductibility.  ATAD  I  was  required  to  be  transposed  into 
domestic  Member  State  law  with  effect  from  January  1, 
2019,  whilst  ATAD  II  was  required  to  be  transposed  into 
domestic Member State law with effect from January 1, 2020 
(with  an  exception  in  respect  of  reverse  hybrid  mismatch 
provisions,  which  will  take  effect  on  January  1,  2022).  On 
December  22,  2021,  the  European  Commission  published  a 
proposal  for  a  Directive  (“ATAD  III”)  laying  down  rules  to 
prevent the misuse of shell entities for improper tax purposes 
and  amending  the  Directive  on  administrative  cooperation 
(Directive  2011/16/EU).  If  adopted,  ATAD  III  will  be 
effective from January 1, 2024. ATAD and ATAD III could 
result in increased tax liabilities and/or compliance costs and 
administrative burden for us.

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  $15.6  billion  in 
capital  at  December  31,  2022  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,  our  experienced  management  team  and  our  strong 
capital base have enabled us to establish a strong presence in 
the insurance and reinsurance markets.

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  is  subject  to  similar 
cycles to property casualty except that they have historically 
been more dependent on macroeconomic conditions.

As  we  head  into  2023,  our  objective  remains  the  same,  to 
deliver  long  term  value  for  our  shareholders.  Underwriting 
discipline is core to our culture and we are committed to agile 
cycle  management  with  a  focus  on  risk-adjusted  returns. 
2022  was  our  third  consecutive  year  of  sustained  premium 
and  revenue  growth,  supporting  stronger  and  more  stable 
earnings power for the near term. Reinsurance segment’s net 
premiums  written  grew  51%  as  the  team  seized  on  market 
dislocations while our insurance segment grew a robust 21%. 
We continue to see a broad array of opportunities to allocate 
capital where rates and terms and conditions allow for growth 
in attractive returns.

We  continue  to  execute  our  cycle  management  strategy  by 
actively  allocating  capital  across  a  diversified,  specialty 
portfolio  where  rates  allow  for  returns  that  are  higher  than 
our  cost  of  capital.  While  we  continue  to  allocate  more 
capital to our property and casualty segments, it is important 
to note that we have capitalized on attractive returns from our 
mortgage  segment  with  $1.3  billion  of  underwriting  income 
in 2022.

The  catastrophic  activity  in  2022  has  significantly  increased 
pressure on property catastrophe markets, which could have a 
ripple  effect  across  all  property  and  casualty  lines.  As  a 
result, we continue to show improved underwriting margins, 
partially  due  to  the  compounding  of  rate-on-rate  increases 
and the rebalancing of our mix of business. We believe that 
this proven strategy of protecting capital through soft markets 
and  increasing  writings  in  hard  markets  gives  us  the  best 
chance to generate superior risk adjusted returns over time.

In reinsurance, pricing for the January 1 renewals was strong. 
Property  catastrophe  pricing  and  terms  both  improved, 
leading  to  the  effective  rate  changes  in  the  30%  to  50% 
range.  We  anticipate  that  these  trends  will  continue  to  the 
mid-year  property  catastrophe  renewal  period  and  should 
translate  to  strong  property  growth  in  2023.  As  long  as  rate 
increases  support  returns  above  our  required  thresholds,  we 
expect to continue to grow our writings. Rate improvements 
have  enabled  us  to  continue  to  expand  writings  in  our 
property casualty segments.

In mortgage, we continue to be thoughtful in how we manage

the ability to take a measured view of the business as just one

measure of the value generated for our common shareholders

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 $32.62 at December 31, 2022, a 2.8% decrease 
from  $33.56  at  December  31,  2021.  The  decline  in  2022 
reflected negative total return on investments driven by rising

investments.  Our  Operating  ROAE  was  14.8%  for  2022, 
compared to 11.5% for 2021, with the higher return in 2022 
primarily  resulting  from  strong  underwriting  performance 
and growth in net investment income, reflecting higher yields 
available on fixed income securities.

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 0.28% and 0.32%, 
respectively, of average invested assets in 2022 and 2021.

Total return for the 2022 period reflected rising interest rates 
on  fixed  maturities  and  weak  equity  markets.  The  overall 
position  of  our  investment  portfolio  remains  relatively 
unchanged as we remain cautious relative to duration, credit 
and equity risk.

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,  2022,  the  benchmark 
return  index  had  an  average  credit  quality  of  “Aa3”  by 
Moody’s, an estimated duration of 3.16 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 
loss  on 
gains  or 
redemption of preferred shares and income taxes, 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 
largely 
realization  of 
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.

is 

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 
share  of  the  net  income  or  loss  of  the  funds  (which  include 
changes  in  the  market  value  of  the  underlying  securities  in 
the  funds).  This  method  of  accounting  is  different  from  the 
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. 

severance, 

Transaction  costs  and  other  include  advisory,  financing, 
legal, 
incentive  compensation  and  other 
transaction  costs  related  to  acquisitions.  We  believe  that 
transaction costs and other, due to their non-recurring nature, 
are  not  indicative  of  the  performance  of,  or  trends  in,  our 
business  performance.  The  loss  on  redemption  of  preferred 
shares related to the redemption of the Company’s preferred 
shares had no impact on shareholders' equity or cash flows.

Due  to  these  reasons  noted  above,  we  exclude  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,  transaction  costs  and  other  and  loss  on 
redemption of preferred shares from the calculation of after-
tax  operating 
common 
shareholders.

above  reflects  the  underlying  fundamentals  of  our  business

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

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 
total  return  on  investments  as  a  key  measure  of  the  return 
generated  to  Arch  common  shareholders  on  the  capital  held 
in  the  business,  and  compares  the  return  generated  by  our 
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, 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.

loss ratios resulted, in part, from changes in mix of business.

Prior Period Reserve Development.

The  insurance  segment’s  underwriting  expense  ratio  was 
34.0% in 2022, compared to 32.1% in 2021, with the increase 
primarily  due  to  changing  mix  of  business  and  growth  in

included  13.9  points  for  current  year  catastrophic  event 
activity, primarily related to Hurricane Ian, Russia’s invasion 
of Ukraine and other global events, compared to 16.5 points 
in 2021. The balance of the change in the 2022 current year 
loss  ratio  resulted,  in  part,  from  the  effect  of  rate  increases, 
changes in mix of business and the level of attritional losses.

was  27.3%  in  2022,  compared  to  26.4%  in  2021,  with  the

The  persistency  rate  of  the  U.S.  primary  portfolio  of 
mortgage loans was 79.5% at December 31, 2022 compared 
to 62.4% at December 31, 2021, 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

Net premiums earned for 2022 were 9.7% lower than in 2021 
and reflected a decline in monthly premiums and an increase 
in ceded premiums earned, partially offset by growth in credit 
risk transfer business. 

Other Underwriting Income.

Other  underwriting  income,  which  is  primarily  related  to 
GSE  risk-sharing  transactions  and  our  whole  mortgage  loan 
purchase  and  sell  program,  was  $8.4  million  for  2022,

Unlike property and casualty business for which we estimate 
ultimate  losses  on  premiums  earned,  losses  on  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 

The  mortgage  segment’s  current  year  loss  ratio  was  2.2 
points higher in 2022 compared to 2021. The higher current 
year loss ratio for the 2022 period reflected a lower level of 
premiums  earned  in  the  U.S.  primary  mortgage  insurance 
business combined with an increase in new delinquencies as 
well as an increase in estimated claim rates. 

The percentage of loans in default on U.S. primary mortgage 
insurance  decreased  from  2.36%  at  December  31,  2021  to 
1.77% at December 31, 2022. 

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 
$554.1 million, or 47.8 points, for 2022, compared to $169.6 
million,  or  13.2  points,  for  2021.  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 20.3% for 2022, compared to 22.7% for 2021, with the 
decrease  primarily  due  to  lower  acquisition  expenses  on 
Australian  mortgage  insurance  following  the  acquisition  of 
Westpac  LMI 
third  quarter  and  profit 
commissions adjustments related to favorable development of 
prior  year  loss  reserves.  Such  amounts  were  partially  offset 
by a lower level of net premiums earned in the U.S. primary 
mortgage insurance business.

other.
Investment  expenses  were  approximately  0.28%  of  average  invested 
assets for 2022, compared to 0.32% for 2021.

(2) 

The  pre-tax  investment  income  yield  was  1.99%  for  2022, 
compared  to  1.41%  for  2021.  The  higher  level  of  net 
investment  income  for  2022  compared  to  2021  reflected 
higher  yields  available  in  the  financial  markets.  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 (Losses). 

We  recorded  net  realized  losses  of  $662.7  million  for  2022, 
compared  to  net  realized  gains  of  $299.2  million  for  2021. 
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.

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. 

We  recorded  $115.9  million  of  equity  in  net  income  related 
to  investments  accounted  for  using  the  equity  method  for 
2022,  compared  to  $366.4  million  for  2021.  Investments 
accounted for using the equity method totaled $3.8 billion at 
December  31,  2022,  compared 
to  $3.1  billion  at 
December  31,  2021.  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 (Loss)

Other loss for the 2022 period was $26.2 million, compared 
to  other  income  of  $10.2  million  for  the  2021  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  $94.4  million  for  2022,  compared 
to $77.1 million for 2021. 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  $1.1  million  for  the  2022 
period  consistent  with  $1.1  million  for  2021.  Amounts  in 
both periods are primarily related to acquisition activity.

Amortization of Intangible Assets.

Amortization  of  intangible  assets  for  2022  was  $106.2 
million,  compared  to  $82.1  million  for  2021.  Amounts  in 
2022  and  2021  primarily  related  to  amortization  of  finite-
lived  intangible  assets.  The  increase  in  amortization  of 
intangible  assets  expense  was  a  result  of  acquisitions  closed 
during the 2021 period. See note 2, “Acquisitions." 

Interest Expense. 

Interest  expense  was  $130.3  million  for  2022,  compared  to 
$131.1  million  for  2021.  Interest  expense  primarily  reflects 
amounts related to our outstanding senior notes.

Net Foreign Exchange Gains or Losses. 

Net  foreign  exchange  gains  for  2022  were  $100.9  million, 
compared  to  net  foreign  exchange  gains  for  2021  of  $42.9 
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  an  expense  of  5.1%  for  2022,  compared  to  an 
expense of 5.6% for 2021. The effective tax rate for the 2022 
period included discrete income tax benefits of $40.6 million, 
compared to benefits of $39.3 million for 2021. The discrete 
tax  items  in  both  periods  primarily  related  to  the  release  of 
valuation  allowances  on  certain  deferred  tax  assets.  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 2022 
and 2021.

Income (Loss) from Operating Affiliates.

We recorded $73.9 million of net income from our operating 
affiliates  in  the  2022  period,  compared  to  income  of  $264.7 
million  in  the  2021  period.  Results  for  the  2021  period 
included  a  one-time  gain  of  $95.7  million  recognized  from 
the  Company’s  investment  in  Greysbridge  and  a  one-time 
gain  of  $74.5  million  recognized  from  the  Company’s 
investment  in  Coface  SA  (“Coface”),  a  France-based  leader 
in the global trade credit insurance market.

Loss on Redemption of Preferred Shares.

In  2021,  we  redeemed  all  5.25%  Series  E  preferred  shares 
and  recorded  a  loss  of  $15.1  million  to  remove  original 
issuance costs related to the redeemed shares from additional 
paid-in  capital.  Such  adjustment  had  no  impact  on  total 
shareholders’ equity or cash flows.

SUMMARY OF CRITICAL ACCOUNTING 
ESTIMATES 

and  other 

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.

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, 2021, 27.9% of total net reserves represent policy years 
2012 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,  2022  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,  2022,  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,  2022,  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, 2022 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, 2022 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  30%  of  the  unpaid  principal  balance  at 
December  31,  2022),  we  estimated  that  our  loss  reserves 
would  change  by  approximately  $21.0  million  at 
December  31,  2022.  For  every  one  percentage  point  change 
in our primary net default to claim rate (which we estimate to 
be approximately 37% at December 31, 2022), we estimated 
a $17.0 million change in our loss reserves at December 31, 
2022.

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,  2022.  Accordingly,  the  reserving  for  incurred 
losses  in  these  lines  of  business  could  be  subject  to  greater 
variability.  See  Item  1A,  “Risk  Factors  –  Risks  Relating  to 
Our  Industry,  Business  &  Operations  –  Underwriting  risks 
and reserving for losses are based on probabilities and related 
modeling, which are subject to inherent uncertainties.”

Simulation Results

In  order  to  illustrate  the  potential  volatility  in  our  Loss 
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,  2022,  our  recorded  Loss  Reserves  by 
underwriting  segment,  net  of  unpaid 
loss 
adjustment  expenses  recoverable,  and  the  results  of  the 
simulation were as follows:

indicated amount.

(3)  Simulation  results  indicate  that  a  10%  probability  exists  that  the  net 
reserves for losses and loss adjustment expenses will be at or below the 
indicated amount.

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 $2.3 billion, or 
$6.14 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 
$2.2 billion, or $5.85 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 
favorably  or  unfavorably  in  the  period  they  are  determined.

Ceded Reinsurance

reinsurance 

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 
reinsurance 
facultative 
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  “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  27.7%  of  gross  premiums 
written  for  2022,  compared  to  29.3%  for  2021.  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 “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

the  unilateral  power  to  direct  those  activities  that  are 
significant to its economic performance. As of December 31, 
2022, our estimated off-balance sheet maximum exposure to 
loss  from  such  entities  was  $26.8  million.  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, 
information. 
similar  business  and  available 
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 
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. 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, 
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.

reinstated 

Reinstatement  premiums  for  our  insurance  and  reinsurance 
operations  are  recognized  at  the  time  a  loss  event  occurs, 
where  coverage  limits  for  the  remaining  life  of  the  contract 
are 
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,  as  described  above  in  “—
Loss Reserves.”

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 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 
the 
transaction,  with  a 
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 
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 
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 
2022 or 2021.

Fair Value Measurements

We review our securities measured at fair value and discuss 
the proper classification of such investments with investment 
advisors  and  others.  See  note  10,  “Fair  Value,”  to  our

Investable Assets

At  December  31,  2022,  total  investable  assets  held  by  Arch 
were $28.1 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 
currently  part  of  our 
investment  strategy.  Our  Chief 
Investment  Officer  administers  the  investment  portfolio, 
oversees our investment managers and formulates investment 
the  FIR  Committee.  At 
strategy 
December 31, 2022, approximately $18.8 billion, or 67%, of 
total investable assets held by Arch were internally managed, 
compared to $18.5 billion, or 67%, at December 31, 2021.

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

Shareholders’ Equity and Book Value per Share

Total  shareholders’  equity  available  to  Arch  was  $12.9 
billion  at  December  31,  2022,  compared  to  $13.5  billion  at 
December 31, 2021. The 2022 period primarily reflected the

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 2022, Arch Capital received dividends of $0.7 billion from 
Arch Reinsurance Ltd. (“Arch Re Bermuda”), our Bermuda-
based  reinsurer  and  insurer  which  can  pay  approximately 
$3.7  billion  to  Arch  Capital  in  2023  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 
period  of  time  from  the  occurrence  of  a  claim  through  the 
settlement  of  the  liability  may  extend  many  years  into  the 
include  cash  flows  from 
future.  Sources  of 
operations,  financing  arrangements  or  routine  sales  of 
investments.

liquidity 

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.

Restricted Assets 

insurance, 

reinsurance  and  mortgage 

Our 
insurance 
subsidiaries are required to maintain assets on deposit, which 
primarily consist of fixed maturities, with various regulatory 
authorities to support their operations. The assets on deposit 
are available to settle insurance and reinsurance liabilities to 
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,  2022  and  2021,  such  amounts 
approximated $8.7 billion and $8.2 billion, respectively.

Our investments in certain securities, including certain fixed 
income  and  structured  securities,  investments  in  funds 
accounted  for  using  the  equity  method,  other  alternative 
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 $2.9 billion at December 31, 2022 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.

Cash  provided  by  operating  activities  for  the  2022  period

2021 period.

Cash  used  for  investing  activities  for  the  2022  period 
reflected  a  higher  level  of  purchases  of  fixed  income 
securities  than  in  the  2021  period,  while  the  2021  period 
reflected cash used for our investment in Coface and Somers.

Cash  used  for  financing  activities  for  the  2022  period 
primarily  reflected  $585.8  million  of  repurchases  under  our 
share  repurchase  program,  compared  to  $1.2  in  the  2021 
period.

Investments 

At  December  31,  2022,  our  investable  assets  were  $28.1 
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

structure.

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, 2022 with a PMIER sufficiency ratio of 
236%, compared to 197% at December 31, 2021.

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,  2022,  Arch  Capital  has 
repurchased 
approximately 433.6 million common shares for an aggregate 
purchase  price  of  $5.9  billion.  At  December  31,  2022,  $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) The  estimated  expected  contractual  commitments  related  to  deposit  accounting  liabilities  have  been  estimated  using  projected  cash  flows  from  the 

underlying contracts. It should be noted that, due to the nature of such liabilities, the timing and amount contain significant uncertainty.

(3) 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.

(4) 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  Secured  Facility  had  $323.1  million  of  letters  of  credit 
outstanding  and  remaining  capacity  of  $101.9  million,  and 
the Unsecured Facility had no outstanding revolving loans or 
letters of credit, with remaining capacity of $500.0 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, 2022.

See  note  19,  “Debt  and  Financing  Arrangements,”  to  our 
consolidated  financial  statements  in  Item  8  for  additional 
disclosures concerning our senior notes and revolving credit 
agreement borrowings.

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  April  7,  2022,  Arch 
Capital  and  certain  of  its  subsidiaries  amended  its  existing 
credit  agreement  into  a  $925.0  million  facility  (the  “Credit 
Facility”) with a syndication of lenders. The Credit Facility, 
as amended, consists of a $425.0 million secured facility for 
letters of credit (the “Secured Facility”) and a $500.0 million 
unsecured  facility  for  revolving  loans  and  letters  of  credit 
(the  “Unsecured  Facility”).  Obligations  of  each  borrower 
under the Secured Facility for letters of credit are secured by 
cash  and  eligible  securities  of  such  borrower  held  in 
collateral  accounts.  Commitments  under  the  Credit  Facility 
may  be  increased  up  to,  but  not  exceeding,  an  aggregate  of 
$1.25 billion. Arch Capital has a 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 terms as the revolving 
loans  except  that  any  prepayments  may  not  be  re-borrowed. 
Arch-U.S.  guarantees  the  obligations  of  Arch  Capital,  and 
Arch  Capital  guarantees 
the  obligations  of  Arch-U.S. 
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. At December 31, 2022,

RATINGS

statistical 

recognized 

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. 

insurance  or 

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

CATASTROPHIC EVENTS AND SEVERE 
ECONOMIC EVENTS 

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.

eliminate  our 

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.

irrespective  of 

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, 2023, 
our modeled peak zone catastrophe exposure is a windstorm 
affecting  the  Florida  Tri-County,  with  a  net  probable 
maximum  pre-tax 
loss  of  $970  million,  followed  by 
windstorms  affecting  the  Northeast  U.S.,  and  the  Gulf  of 
Mexico  with  net  probable  maximum  pre-tax  losses  of  $908 
million  and  $903  million,  respectively.  As  of  January  1, 
2023,  our  modeled  peak  zone  earthquake  exposure  (San 
Francisco  area  earthquake)  represented  approximately  60% 
of our peak zone catastrophe exposure, and our modeled peak 
zone 
(U.K.  windstorm)  was 
substantially  less  than  both  our  peak  zone  windstorm  and 
earthquake exposures.

exposure 

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,

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, 2023, our modeled 
RDS  loss  was  12.3%  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  “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

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, 2022. 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, 2022 
presents  hypothetical  losses  in  cash  flows,  earnings  and  fair 
values of market sensitive instruments which were held by us 
on December 31, 2022 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.

these  projected  results  due 

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, 2022 and 2021:

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.

parallel  shift  in  credit  spreads  in  a  static  interest  rate 
environment  would  have  had  on

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

Table of Contents

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, 2022, our portfolio’s 95th percentile VaR was 
estimated  to  be  8.8%,  compared  to  an  estimated  4.8%  at 
December 31, 2021. 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,  2022  and  2021,  the  fair 
value  of  our  investments  in  equity  securities  and  certain 
investments  accounted  for  using  the  equity  method  with 
underlying  equity  strategies  totaled  $0.8  billion  and  $1.4 
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  $79.1  million  and  $137.5  million  at 
December 31, 2022 and 2021, respectively, and would have 
decreased book value per share by approximately  $0.21 and 
$0.36, respectively. An immediate hypothetical 10% increase 
in the value of each position would increase the fair value of 
such investments by approximately $79.1 million and $137.5 
million  at  December  31,  2022  and  2021,  respectively,  and 
would have increased book value per share by approximately 
$0.21 and $0.36, respectively.

Investment-Related  Derivatives.  At  December  31,  2022,  the 
notional  value  of  all  derivative  instruments  (excluding 
foreign currency forward contracts which are included in the 
foreign  currency  exchange  risk  analysis  below)  was  $6.6 
billion, compared to $6.4 billion at December 31, 2021. If the 
underlying  exposure  of  each  investment-related  derivative 
held at December 31, 2022 depreciated by 100 basis points, it 
would  have  resulted  in  a  reduction  in  net  income  of 
approximately  $66.3  million,  and  a  decrease  in  book  value 
per  share  of  $0.18,  compared  to  $63.8  million  and  $0.17, 
respectively,  on 
investment-related  derivatives  held  at 
December  31,  2021.  If  the  underlying  exposure  of  each 
investment-related  derivative  held  at  December  31,  2022 
appreciated by 100 basis points, it would have resulted in an 
increase  in  net  income  of  approximately  $66.3  million,  and 
an  increase  in  book  value  per  share  of  $0.18,  compared  to 
$63.8  million  and  $0.17,  respectively,  on  investment-related 
derivatives  held  at  December  31,  2021.  See  note  11, 
“Derivative  Instruments,”  to  our  consolidated  financial 
statements  in  Item  8  for  additional  disclosures  concerning 
derivatives.

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 
additional information.

The  following  table  provides  a  summary  of  our  net  foreign

the  Company’s  exposure 

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, 2022 and 2021, 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, 2022, 
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, 2022, 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, 2022 and 2021, and the results of its operations and its cash flows for each of the 
three years in the period ended December 31, 2022, 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, 2022, 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.

Table of Contents

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 matter communicated below is a matter arising from the current period audit of the consolidated financial 
statements that was communicated or required to be communicated to the audit committee and that (i) relates 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 matter below, providing a separate 
opinion on the critical audit matter or on the accounts or disclosures to which it relates.

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, 2022, the Company’s total reserve for losses and 
loss adjustment expenses was $20.0 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, which in turn led to a high degree of auditor subjectivity and judgment in performing procedures related to the 
valuation of the reserve for losses and loss adjustment expenses, (ii) the significant auditor effort and judgment in evaluating 
audit evidence related to the aforementioned key actuarial methods and key assumptions, and (iii) the audit effort included the 
involvement of professionals with specialized skill and knowledge to assist in performing these procedures and evaluating the 
audit evidence obtained.

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.

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

that  relates  to  the  unexpired  terms  of  in-force  insurance 
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

acquisition  expenses  based  upon  the  experience  under  the

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.

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 
based on the terms of the underlying contracts.

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.  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 
adjustment  expenses.  For  each  underwriting  year,

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 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

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

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 
of  reinsurance  ceded.  See  note  8,  “Reinsurance”  for 
information  on 
reinsurance  usage. 
Reinsurance  premiums  ceded  and  unpaid  losses  and  loss 
adjustment  expenses  recoverable  are  estimated  in  a  manner 
consistent  with  that  of  the  original  policies  issued  and  the 
terms of the reinsurance contracts. 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.

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

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.

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

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 
prepayments

significantly 
prepayments,  the  effective  yield  is  recalculated  to  reflect 
actual payments to date and anticipated future payments. The 
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  2022,  2021,  and  2020,  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

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 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.

(n) Share-Based Payment Arrangements

its 

in  accounting 

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

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. 
See  note  22,  “Share-Based  Compensation”  for  information 
relating to the Company’s share-based payment awards.

(o) Guaranty Fund and Other Related Assessments

Liabilities for guaranty fund and other related assessments in 
the  Company’s  insurance  and  reinsurance  operations  are 
accrued when the Company receives notice that an amount is 
payable, or earlier if a reasonable estimate of the assessment 
can be made.

(p) Treasury Shares

Treasury  shares  are  common  shares  purchased  by  the 
Company  and  not  subsequently  canceled.  These  shares  are 
recorded  at  cost  and  result  in  a  reduction  of  the  Company’s 
shareholders’ equity in its Consolidated Balance Sheets.

(q) Goodwill and Intangible Assets

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 

ARCH CAPITAL

Table of Contents

ARCH CAPITAL GROUP LTD. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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.

(s) Funds Held Arrangements

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 Adopted

The  Company  adopted  ASU  2019-12,  “Simplifying  the 
Accounting for Income Taxes.” This ASU eliminates certain 
exceptions  for  recognizing  deferred  taxes  for  investments, 
performing intraperiod tax allocations and calculating income 
taxes  in  interim  periods.  The  ASU  also  clarifies  the 
accounting for transactions that result in a step-up in the tax 
basis of goodwill. The adoption of this guidance did not have 
a  material  effect  on  the  Company’s  consolidated  financial 
statements.

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.

determined  its  reportable  segments  using  the  management 
approach  described 
regarding 
disclosures  about  segments  of  an  enterprise  and  related

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 includes

Year Ended December 31, 2022

During 2022, the Company recorded estimated net favorable 
development  on  prior  year  loss  reserves  of  $771.0  million, 
which  consisted  of  net  favorable  development  of  $25.3 
million from the insurance segment, $191.6 million from the 
reinsurance  segment  and  $554.1  million  from  the  mortgage

The insurance segment’s net favorable development of $25.3 
million,  or  0.6  points  of  net  earned  premium,  consisted  of 
$55.3  million  of  net  favorable  development  in  short-tailed 
lines  partially  offset  by  $29.9  million  of  net  adverse 
development  from  medium-tailed  and  long-tailed  lines.  Net 
favorable  development 
reflected 
$37.4  million  of  favorable  development  in  warranty  and 
lenders solutions, primarily from the 2021 accident year (i.e., 
the  year  in  which  a  loss  occurred),  and  $14.8  million  of 
travel  and  accident

in  short-tailed 

lines 

to 

business,  primarily  from  the  2020  and  2021  accident  years. 
Net  adverse  development  in  medium-tailed  lines  reflected 
$24.7 million of adverse development in professional liability 
business, primarily from the 2013 to 2015 and 2018 to 2020 
accident  years,  and  $6.4  million  of  adverse  development  in 
contract  binding  business,  across  most  accident  years, 
partially offset by $12.9 million of favorable development in 
marine  business,  across  most  accident  years.  Net  adverse 
development  in  long-tail  lines  reflected  $18.5  million  of 
adverse  development  related  to  casualty  business,  primarily 
from  the  2020  and  2021  accident  years,  and  $7.3  million  of 
adverse  development  on  construction  and  national  accounts, 
primarily from the 2017, 2020 and 2021 accident years. This 
is partially offset by $21.5 million of favorable development 
in  other  business,  including  alternative  markets  and  excess 
workers’  compensation,  primarily  from  the  2019  and  prior 
accident years.

lien  portfolio  from  the  2020  and  2021  accident  years.  The 
Company’s credit risk transfer, international, second lien and 
student  loan  businesses  also  contributed  to  the  favorable 
development.

improving  economic  conditions  and  rising  home  prices, 
in  reduced  claim  rate  assumptions  primarily 
resulting

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.

from 

The  reinsurance  segment’s  net  favorable  development  of 
$134.0  million,  or  6.2  points  of  net  earned  premium, 
consisted  of  $155.9  million  of  net  favorable  development 
from short-tailed and medium-tailed lines, partially offset by 
$21.9  million  of  net  adverse  development  from  long-tailed 
lines. Net favorable development of $144.0 million in short-

business,  primarily  from  the  2015  to  2019  underwriting 
years,  and  $53.6  million  from  other  specialty  lines,  across 
most underwriting years. The net reduction of loss estimates 
for  the  reinsurance  segment’s  short-tailed  lines  primarily 
resulted  from  varying  levels  of  reported  and  paid  claims 
activity than previously anticipated which led to decreases in
certain 
selections  during  2020.  Adverse 
development  in  long-tailed  lines  reflected  an  increase  in 
casualty, primarily from the 2012 to 2015 underwriting years.

The  mortgage  segment’s  net  favorable  development  of 
$19.0 million, or 1.4 points of net earned premium, included 
$16.2  million  of  favorable  development  on  U.S.  primary 
mortgage 
insurance  business.  Such  development  was 
primarily  driven  by  subrogation  recoveries  on  second  lien 
business and student loan business.

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”.

In  2020,  the  Company  entered  into  a  reinsurance-to-close 
agreement  related  to  a  third  party  arrangement  covering  the 
2017 and prior years of account for certain London syndicate 
business. 

6.  Short Duration Contracts

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 
in  determining  the  level  of  disaggregation  for  disclosures 
related to its short-duration contracts, as detailed in the table

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.

losses  and 

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.

insureds  and  administer 

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.

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

including 

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. 
Unpaid  loss  and  loss  adjustment  expenses  recoverable  at

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, 
2022  there  were  no  significant  backlogs  related  to  the 
processing  of  assumed  reinsurance  information  at  our 
reinsurance operations.

ARCH CAPITAL GROUP LTD. AND SUBSIDIARIES
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,

ultimate  loss  ratio  at  the  time  the  contract  is  entered  into,

and  claims  personnel  and  underwriters’  analyses  of  our

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

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

to  current  reserve 

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

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 
of  delinquent 
loans  and  claims  notices  from  ceding 
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

agreements  with  various  special  purpose

to  satisfy  their  obligations  under  the  agreements,  the 
Company’s  insurance  or  reinsurance  subsidiaries  would  be 
liable for such defaulted amounts.

ARCH CAPITAL GROUP LTD. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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 
Noncontrolling Interests.”

The following table summarizes the respective coverages and 
retentions at December 31, 2022:

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.

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 
aggregate  amount  of 
requests  exceeds  a 
redemption 
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 
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 $74.5 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,  2022,  the  Company 
owned approximately 29.9% of the issued shares of Coface, 
or 30.1% excluding treasury shares, with a carrying value of 
$562.9 million, compared to $630.5 million at December 31, 
2021.

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.

with income (loss) from operating affiliates, which included a 
one-time  gain  of  $95.7  million  recognized  from 
the 
acquisition.  In  addition,  the  ‘net  realized  gains  (losses)’  line

10.  Fair Value

ARCH CAPITAL GROUP LTD. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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  $23.8  billion  of 
financial  assets  and  liabilities  measured  at  fair  value  at 
December  31,  2022,  approximately  $12.6  million,  or  0.1%, 
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, 2021, approximately $7.7 million, 
or 0.0%, 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:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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.

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  other  short-term 
investments are generally determined using the spread above 
the risk-free yield curve and are classified within Level 2.

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, 2022, 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,  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. At December 31, 2021, 
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 
$3.3 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:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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 
forward  contracts, 
foreign  currency 
routinely  utilizes 
currency  options, 
futures  contracts  and  other 
index 
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.

to-be-announced 
In  addition, 
the  Company  purchases 
its 
mortgage  backed  securities  (“TBAs”)  as  part  of 
investment  strategy.  TBAs 
to 
represent  commitments 
purchase  a  future  issuance  of  agency  mortgage  backed 
securities.  For  the  period  between  purchase  of  a  TBA  and 
issuance  of  the  underlying  security,  the  Company’s  position 
is  accounted  for  as  a  derivative.  The  Company  purchases 
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,  2022  or 
2021. 

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. 

At  December  31,  2022,  $147.4  million  and  $73.2  million, 
respectively,  of  asset  derivatives  and  liability  derivatives 
were  subject  to  a  master  netting  agreement  compared  to 
$122.3  million  and  $53.9  million, 
respectively,  at 
December  31,  2021.  The  remaining  derivatives  included  in 
the  table  above  were  not  subject  to  a  master  netting 
agreement.

Somers Holdings Ltd.

In  March  2014,  the  Company  invested  $100.0  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

Bellemeade Re

ARCH CAPITAL GROUP LTD. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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.

exposure to loss associated with these VIEs, calculated as the

maximum  historical  observable 
benchmark  index  for  each  respective  transaction  and  short 
term  invested  trust  asset  yields.  The  benchmark  index  for 
agreements  effective  prior  to  2021  is  based  on  one-month 
LIBOR,  while  the  2021  and  later  agreements  benchmark 
index  is  based  on  the  Secured  Overnight  Financing  Rate 
(“SOFR”). SOFR is a measure of the cost of borrowing cash 
overnight,  collateralized  by  U.S.  Treasury  securities,  and  is 
based  on  directly  observable  U.S.  Treasury-backed 
repurchase transactions.

15.   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 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.  This 
undertaking  does  not,  however,  prevent  the  imposition  of 
taxes  on  any  person  ordinarily  resident  in  Bermuda  or  any 
company  in  respect  of  its  ownership  of  real  property  or 
leasehold interests in Bermuda.

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. 

intend 

to  conduct 

its  non-U.S.  subsidiaries 

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 
and 
their 
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 
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

(1)  On  January  30,  2014,  the  Company’s  U.S.  mortgage  operations 
underwent  an  ownership  change  for  U.S.  federal  income  tax  purposes  as  a 
result of the Company’s acquisition of the CMG Entities. As a result of this 
ownership  change,  a  limitation  has  been  imposed  upon  the  utilization  of 
approximately  $7.0  million  of  the  Company’s  existing  U.S.  net  operating 
loss  carryforwards.  Utilization  is  limited  to  approximately $0.6  million  per 
year in accordance with Section 382 of the Internal Revenue Code of 1986 
as amended (“the Code”).

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  $12.4 
million at December 31, 2022, compared to $31.6 million at 
December 31, 2021.

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  no  longer 
intends 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, 2022, the Company’s total unrecognized 
tax  benefits,  including  interest  and  penalties,  were  $2.0 
million.  If  recognized,  the  full  amount  of  the  unrecognized

Inflation Reduction Act of 2022. 

On  August  16,  2022,  the  U.S.  government  enacted  the 
Inflation  Reduction  Act  of  2022,  which  among  other  things 
implements  a  15%  minimum  tax  on  book  income  of  certain 
large corporations, a 1% excise tax on net stock repurchases 
and  several  tax  incentives  to  promote  clean  energy.  The 
effective  date  of  these  provisions  is  January  1,  2023.  Based 
on  its  current  analysis  of  the  provisions,  the  Company  does 
not expect that this legislation will have a material effect on 
the Company’s consolidated financial statements.

reserve  portfolios  in  the  non-life  property  and  casualty 
insurance and reinsurance run-off market. Arch Re Bermuda 
and  certain  Arch  co-investors  invested  $100.0  million  and 
acquired approximately 25% of Premia as well as warrants to 
purchase additional common equity. Arch has appointed two 
directors  to  serve  on  the  seven  person  board  of  directors  of 
Premia.  Arch  Re  Bermuda  is  providing  a  25%  quota  share 
reinsurance  treaty  on  certain  business  written  by  Premia. 
During  2022,  Arch  Re  Bermuda  entered 
into  certain 
reinsurance  transactions  with  Premia  which  generated  net 
premiums  written  and  earned  of  $121.1  million  and 
$119.9  million,  respectively,  compared  to  $40.4  million  of 
net  premiums  written  and  earned  in  2021.  At  December  31, 
2022,  Arch  Re  Bermuda  recorded  a  funds  held  asset  from 
Premia  of  $118.7  million,  compared  to  $53.5  million  at 
December 31, 2021.

In the 2021 first quarter, as part of the Company’s acquisition 
of  Barbican,  the  Company  entered  into  an  agreement  with 
Premia  Managing  Agency  Limited  for  the  reinsurance  to 
close of Syndicate 1955’s 2018 underwriting year of account 
into  Premia  Syndicate  1884’s  2021  underwriting  year  of 
account.  The  reinsurance  to  close  covers  legacy  business 
underwritten  by  Syndicate  1955  on  the  underwriting  2018 
and  prior  years  of  account  and  under  the  agreement, 
approximately $380 million of net liabilities was transferred 
to Syndicate 1884, with an effective date of January 1, 2021. 
The Company had no reinsurance recoverable on unpaid and 
paid losses or funds held liability at December 31, 2022 and 
December 31, 2021.

pursuant  to  which  Somers  became  wholly  owned  by 
Greysbridge,  and  Greysbridge 
the 
Company, 30% by certain funds managed by Kelso and 30% 
by certain funds managed by Warburg. During the 2022 and 
2021  period,  the  Company  entered  into  certain  reinsurance 
transactions  with  Somers.  The  Company’s  net  premiums 
written  was  reduced  by  $519.4  million  and  $379.1  million, 
for the 2022 and 2021 periods, respectively (which included 
reinsurance  transactions  as  well  as  those  entered  into  in 
conjunction  with  the  Merger  Agreement).  In  addition, 
Somers paid certain acquisition costs and administrative fees 
to  the  Company.  At  December  31,  2022,  the  Company 
recorded a reinsurance recoverable on unpaid and paid losses 
from  Somers  of  $1.2  billion  and  a  reinsurance  balance 
payable to Somers of $413.8 million. At December 31, 2021,

reinsurance  recoverable  on  unpaid  and  paid  losses  from 
Somers  was  $902.8  million,  with  a  reinsurance  balance 
payable to Somers of $258.4 million. See note 12, “Variable 
Interest Entity and Noncontrolling Interests.”

The  Company  has  a  put/call  option  that  was  entered  into  in 
connection  with  the  Greysbridge  equity  financing,  whereby 
beginning January 1, 2024 the Company will have a call right 
(but  not  the  obligation)  and  Warburg  and  Kelso  will  each 
have a put right (but not the obligation) to buy/sell one third 
of their initial shares annually at the tangible book value per 
share  of  Greysbridge  for  the  most  recently  ended  fiscal 
quarter.

As of December 31, 2022, the Company owns $35.0 million 
in  aggregate  principal  amount  of  Somers  6.5%  senior  notes, 
due July 2, 2029.

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 10 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.

The areas where significant concentrations of credit risk may 
exist  include  unpaid  losses  and  loss  adjustment  expenses 
recoverable,  contractholder  receivables,  ceded  unearned 
loss  adjustment  expenses 
premiums,  paid 
recoverable net of reinsurance balances payable, investments 
and  cash  and  cash  equivalent  balances.  A  credit  exposure

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

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  April  7,  2022,  Arch 
Capital  and  certain  of  its  subsidiaries  amended  its  existing 
credit  agreement  into  a  $925.0  million  facility  (the  “Credit 
Facility”) with a syndication of lenders. The Credit Facility, 
as amended, consists of a $425.0 million secured facility for 
letters of credit (the “Secured Facility”) and a $500.0 million 
unsecured  facility  for  revolving  loans  and  letters  of  credit 
(the  “Unsecured  Facility”).  Obligations  of  each  borrower 
under the Secured Facility for letters of credit are secured by 
cash  and  eligible  securities  of  such  borrower  held  in 
collateral  accounts.  Commitments  under  the  Credit  Facility 
may  be  increased  up  to,  but  not  exceeding,  an  aggregate  of 
$1.25 billion. Arch Capital has a 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 terms as the revolving 
loans  except  that  any  prepayments  may  not  be  re-borrowed. 
Arch-U.S.  guarantees  the  obligations  of  Arch  Capital,  and 
Arch  Capital  guarantees 
the  obligations  of  Arch-U.S. 
Borrowings of revolving loans may be made at a variable rate 
based  on  SOFR.  Secured  letters  of  credit  are  available  for 
issuance  on  behalf  of  certain  Arch  Capital  subsidiaries.  At 
December 31, 2022, the Secured Facility had $323.1 million 
of  letters  of  credit  outstanding  and  remaining  capacity  of 
the  Unsecured  Facility  had  no 
$101.9  million,  and

Commitments  under  the  Credit  Facility  will  expire  on

will  not  have  an  expiration  date  later  than  December  17, 
2025.

In  addition,  certain  of  Arch  Capital’s  subsidiaries  had 
outstanding  secured  and  unsecured  letters  of  credit  through 
other  facilities  of  $24.6  million  and  $400.0  million 
respectively,  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.  This 
is required to ensure that such counterparties are permitted to 
take  credit  for  reinsurance  obtained 
in  United  States 
jurisdictions  where  such  subsidiaries  are  not  licensed  or 
otherwise admitted as an insurer, as required under insurance 
regulations  in  the  United  States,  and  to  comply  with 
requirements  of  Lloyd’s  of  London  in  connection  with 
qualifying  quota  share  and  other  arrangements.  The  amount 
of  letters  of  credit  issued  is  driven  by,  among  other  things,

such reserves, the further expansion of business and the loss

value  of  $465.2  million.  The  Company  had  no  outstanding 
revolving credit agreement borrowings at December 31, 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, 2022, 
$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, 
2022, Arch Capital held 217.9 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:

repurchased 
approximately 433.6 million common shares for an aggregate 
purchase price of $5.9 billion. 

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 
1/1,000th  interest  in  a  share  of  its  4.55%  Non-Cumulative 
Preferred  Shares,  Series  G,  $0.01  par  value  and  $25,000

liquidation  preference  per  share 
liquidation  preference  per  Depositary  Share)  (the  “Series  G 
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.

preferred  shares  were  redeemed  at  a  redemption  price  equal 
to  $25  per  share,  plus  all  declared  and  unpaid  dividends  to

Stock Options and Stock Appreciation Rights

The  Company  generally  issues  stock  options  and  SARs  to 
eligible  employees,  with  exercise  prices  equal  to  the  fair 
market  values  of  the  Company’s  Common  Shares  on  the 
grant  dates.  Such  grants  generally  vest  over  a  three  year 
period  with  one-third  vesting  on  the  first,  second  and  third 
anniversaries of the grant date.

The  grant  date  fair  value  is  determined  using  the  Black-
life 
Scholes  option  valuation  model.  The  expected 
assumption  is  based  on  an  expected  term  analysis,  which 
incorporates  the  Company’s  historical  exercise  experience.

The aggregate intrinsic value of restricted units outstanding at

The Company also issues performance share and unit awards 
(“performance  awards”)  to  eligible  employees,  which  are 
the  achievement  of  pre-established 
earned  based  on 
three-year 
target  and  maximum  goals  over

There  were  no  state-prescribed  or  permitted  regulatory 
accounting  practices  for  any  of  the  Company’s  insurance  or 
reinsurance entities that resulted in reported statutory surplus 
that differed from that which would have been reported under 
the  prescribed  practices  of 
regulatory 
authorities,  including  the  National  Association  of  Insurance 
Commissioners.  The  differences  between  statutory  financial 
statements  and  statements  prepared  in  accordance  with 
GAAP  vary  by  jurisdiction,  however,  with  the  primary 
differences being that statutory financial statements may not 
reflect  deferred  acquisition  costs,  certain  net  deferred  tax 
assets, goodwill and intangible assets, unrealized appreciation 
or  depreciation  on  debt  securities  and  certain  unauthorized 
reinsurance recoverables and include contingency reserves.

The statutory net income (loss) for the Company’s principal 
operating  subsidiaries  for  2022,  2021  and  2020  was  as

reinsurance 
The  Company’s  Bermuda 
subsidiaries  are  subject  to  the  Bermuda  Insurance  Act  1978 
and  related  regulations,  each  as  amended  (the  “Insurance 
Act”).  Arch  Re  Bermuda, 
the  Company’s  principal 
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,  2022 
and  2021,  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  $3.7  billion  to 
Arch  Capital  during  2023  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,  2022  and  2021,  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  $255.4  million  of 
dividends  during  2023  subject  to  the  approval  of  the 
Commissioner of the Delaware Department of Insurance.

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 $156.5 million of ordinary dividends in 2023, 
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,  2022  and 
2021, 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

In  connection  with  the  filing  of  this  Form  10-K,  our 
management,  including  the  Chief  Executive  Officer  and 
Chief  Financial  Officer,  conducted  an  evaluation,  as  of 
December  31,  2022,  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 the disclosure controls and procedures 
are 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 
the  degree  of 
because  of  changes 

in  conditions,  or 

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 

is  responsible  for  establishing  and 
Our  management 
maintaining  adequate 
financial 
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,  2022.  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,  2022,  our  internal  control  over  financial 
reporting  was  effective.  The  effectiveness  of  our  internal 
control over financial reporting as of December 31, 2022 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 
Exchange  Act  during  the  fiscal  quarter  ended  December  31, 
2022 that have materially affected, or are reasonably likely to 
materially affect, internal control over financial reporting.
