To Our Shareholders:

  Arch’s  business  model  is  aimed  at  growing  book  value  per  share. The  Company’s  diversification  across  three 

segments—property casualty insurance, property casualty reinsurance and mortgage insurance and reinsurance—

supports that model by giving us opportunities to invest in the sectors and product lines that offer the best potential 

risk-adjusted returns at any given time. At the same time, we are underweight in those sectors and product lines 

in  which  we  perceive  the  risk-adjusted  returns  to  be  inadequate.  Our  allocation  of  capital  across  segments  is 

dynamic—we increase or reduce our allocation among and within segments as opportunities emerge or diminish.

  The  soundness  of  our  model  proved  itself  again  in  2018  as  we  performed  well  financially,  despite  a  second 

consecutive  year  of  unusually  high  industry-wide  property  casualty  catastrophe  losses.  We  fared  well  in  2018 

compared  to  the  property  casualty  industry  because  we  were  relatively  underweight  in  property  catastrophe 

coverages, where we felt pricing was inadequate, while we allocated a significant portion of our capital to mortgage 

insurance and other sectors that provided favorable expected returns.

Book Value per Share and Operating Return on Equity

  Book value per share is a key measure used to evaluate the Company’s performance, since we believe increases in 

this metric over time are what ensure the creation of long-term value for shareholders. The Company’s book value 

per share rose to $21.52 at the end of 2018, up 6.0% from year-end 2017, the 10th consecutive annual increase. 

Book value per share has now grown at an average annual rate of 14.2% over the past decade. 

* Please refer to “Net Income, Operating Income, Underwriting Results and Cash” for a discussion of the components of net income available 
to common shareholder and after-tax operating income. After-tax operating income, which is a non-GAAP measure of financial performance, 
is defined as net income available to common shareholders, excluding net realized gains or losses, net impairment losses included in earnings, 

equity in net income or loss of investment funds accounted for using the equity method, net foreign exchange gains or losses, transaction costs 

and other and loss on redemption of preferred shares, net of income taxes. The reconciliation of net income available to common shareholders 

to after-tax operating income can be found in the Company’s Annual Report on Form 10-K, filed with the SEC on February 28, 2019, under the 

caption “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” A copy of the Form 10-K is available on the 

Company’s web site and accompanies this letter.

  
 
 
 
  Operating return on equity (“ROE”) is a key driver of book value growth. The Company’s operating ROE was 

10.7% in 2018, up from 5.7% in 2017, and has averaged 10.3% during the past decade. Operating ROE consists 

primarily of underwriting income and net investment income and excludes net realized gains and losses, equity in 

net income and losses of investment funds accounted for using the equity method, net foreign exchange gains and 

losses and other “non-operating” items.

  All financial results in this letter are presented on a core basis, which excludes amounts related to the “other” 

segment, i.e., Watford Holdings Ltd. (“Watford”). In accordance with GAAP, 100% of the results of Watford are 
included in the Company’s consolidated financial statements even though the Company owns only about an 11% 

equity  interest  in  Watford.  We  believe  core  results  offer  a  more  meaningful  way  for  investors,  analysts,  rating 

agencies and others to evaluate the Company’s performance. Results for the “other” segment can be found on pages 

110 to 116 of the Company’s Form 10-K for 2018.

Core Principles, Earnings and Underwriting Results

  The Company writes specialty lines of insurance and reinsurance in which we seek to employ our knowledge, 

skills and strong capital base to competitive advantage. We are deeply committed in all our lines to our operating 

principles of innovation, sound risk selection, underwriting discipline, diversification and deploying our capital only 

when we believe the risk-adjusted return opportunities available to us meet our objectives. 

  The Company’s net income reached $713.6 million, or $1.73 per share, in 2018, rising 27.2% from 2017 on a per-share 

basis. After-tax operating income increased to $909.2 million, or $2.20 per share, up 105.6% on a per-share basis.

  Underwriting income advanced 75.6%, to $897.1 million, as we continued to benefit from our diverse portfolio 

of insurance and reinsurance businesses. The Company’s combined ratio—a measure of underwriting profitability— 

improved to 81.0% in 2018 from 88.8% in 2017. A combined ratio below 100% indicates an underwriting profit. 

All three business segments contributed to the 2018 improvement, led by our mortgage insurance group.

  Results  for  2018  included  $193.3  million  of  catastrophe  losses,  down  from  $385.8  million  in  2017. We  have 

scaled back our participation in the property catastrophe insurance and reinsurance markets over the last several 

years, reflecting the lack of attractiveness in the risk-reward characteristics of these markets. Property catastrophe 

coverage represented 5.8% of our net reinsurance premiums written in 2018, down from 6.0% in 2017 and 25.9% in 

2011. Major natural disasters in 2018 included Hurricane Michael in the southeastern United States and wildfires in 

California, amid ongoing public concern about the impact of climate change. It is uncertain whether climate change 

will lead to an increased pattern of natural disasters and persistently high catastrophe losses, but we remain alert to 

the issue and continue to factor it into our assessment of pricing adequacy.

  Net favorable reserve development was $270.5 million in 2018, essentially unchanged from 2017, as earlier-year 

reserves proved to be more than adequate, resulting in the release of a portion of these reserves to earnings. While 

2018  represented  our  16th  consecutive  year  of  favorable  reserve  development,  we  review  the  adequacy  of  our 

reserves quarterly and there is no guarantee that favorable reserve development will continue in the future.

2

  We continued to generate a healthy level of cash flow. Net cash provided by operating activities was $1.3 billion in 

2018, up from $0.8 billion in 2017, reflecting a variety of factors, including the solid performance of our business units.

Investment Results

  Total investable assets were $19.6 billion at the end of 2018, down slightly from year-end 2017, as we repaid debt 

and returned capital to shareholders through share repurchases. Net investment income was $438.0 million, or $1.06 

per share, in 2018, advancing 16.5% from 2017 on a per-share basis.

  The year was challenging for investors, as both the fixed income and equity markets provided meager or negative 

returns.  The  benchmark  10-year  U.S.  Treasury  note  had  a  total  return  of  -0.03%,  while  the  U.S.  stock  market 

returned -4.38%, as measured by the S&P 500 Index. We maintained a defensive posture through our investments 

in high-quality fixed income securities and the relatively short average duration of our fixed income holdings. At 

year-end 2018, approximately 81% of the portfolio was invested in fixed maturity and short-term securities, with an 

average credit quality of “AA/Aa2.” The average effective duration of the portfolio was 3.38 years at December 31, 

2018, and 2.83 years at the end of 2017. In addition, we allocate a portion of the portfolio to alternative investments 

and equities, which provide diversification and offer the potential for higher returns. Such investments accounted 

for approximately 16% of the portfolio at the end of 2018.

  Our  investment  approach  stresses  preservation  of  capital,  market  liquidity  and  diversification  of  risk. We  also 

focus on maximizing total return, which contributes to increases in book value per common share but may not be 

entirely reflected in operating income or net income. Total return (consisting of net investment income, net realized 

gains and losses, changes in unrealized gains and losses and equity in the net income or losses of investment funds 

accounted for using the equity method) was 0.33% in 2018 compared to 5.87% in 2017. All components of total 

return, except for changes in unrealized gains and losses, are included in the Company’s net income, while only net 

investment income is included in operating income.

  Market values for many types of fixed income securities declined in 2018 as interest rates rose—hence our low 

total  return  for  the  year.  Even  though  higher  interest  rates  negatively  affected  the  market  value  of  many  of  our 

fixed income holdings, they provided opportunities to invest new money at higher yields, which could benefit the 

Company going forward. The pre-tax investment income yield of the portfolio was 2.36% for 2018 and 2.06% for 

2017, while the embedded book yield, before investment expenses, increased to 2.89% at the end of 2018 from 

2.32% a year earlier.

  As  discussed  in  prior  letters,  we  divide  the  portfolio  for  investment  purposes  into  three  main  categories: 

investments generated from our insurance, reinsurance and mortgage operations cash flows; investments supported 

by our debt and hybrid securities; and investments supported by common shareholders’ equity. For our insurance, 

reinsurance and mortgage liabilities, we generally attempt to match, within a reasonable range, the duration of our 

investments to the duration of the underlying claim obligations. We manage the portfolio conservatively to protect 

our reserves on an economic basis and ensure our ongoing ability to pay claims. For our debt and hybrid securities 

3

 
and common shareholders’ equity, we vary the duration of the portfolio based on our view of potential returns and 

the outlook for investments and the economy in general.

Market Segments

  Arch writes property casualty insurance and reinsurance for commercial accounts primarily from operations in 

Bermuda, the United States, Canada and Europe. We write mortgage insurance and reinsurance in the United States, 

Bermuda,  Europe, Australia  and  Hong  Kong.  Companywide,  net  premiums  written  were  $4.7  billion  in  2018,  a 

7.6% increase over 2017.

  Technology continues to be an increasingly powerful tool in all our segments, helping us reduce costs, make more 

informed underwriting decisions and deliver better service to our customers. Our use of data analytics to assess 

risk more accurately and enable risk-based pricing is an example: we pioneered risk-based pricing in the mortgage 

insurance business with RateStar, which tailors pricing to a homebuyer’s individual risk characteristics, rather than 

using a standardized rate card. RateStar allows us to provide more granular pricing on each loan, based on its risk 

characteristics. We continue to expand the use of data analytics in other parts of our business.

  Property  casualty  insurance:  Based  on  premiums  written,  this  is  our  largest  segment,  accounting  for  47%  of 
the Company’s premium volume in 2018. Net premiums written were $2.21 billion in 2018, up 4.2% from 2017. 

Insurance pricing has been under pressure for several years and competition is especially fierce in the insurance 

purchases of the largest corporations. Consequently, our underwriting results have not met our return hurdles for 

the past two years, although they improved significantly in 2018.

  Over  the  past  several  years,  we  have  responded  to  an  extended  soft  market  by  carving  out  positions  in  those 

specialty areas where we see attractive, long-term opportunities. For example, in 2018, we continued to build our 

position in travel and accident insurance. This product line accounted for 13.1% of the segment’s net premiums 

written in 2018, up from 11.7% in 2017 and 4.2% in 2011. In addition, we continued to migrate toward serving 

smaller and mid-sized corporate clients, where insurance is less commoditized and we can get closer to the insured 

and  provide  added  value. We  announced  the  acquisition  of  two  companies  in  2018  in  support  of  this  objective. 

McNeil  &  Co.,  which  provides  risk  management  services  and  insurance  programs  to  businesses  in  the  United 

States,  was  acquired  in  December.  On  January  1,  2019,  we  completed  the  acquisition  of  the  commercial  lines 

business of The Ardonagh Group in the U.K., including commercial property, casualty, motor, professional liability, 

personal accident and travel insurance.

  Property casualty reinsurance: This segment represented 29% of the Company’s premium volume in 2018 as net 
premiums written increased 16.9% to $1.37 billion for the year. In 2018, as in 2017, our growth reflected increased 

writings of motor business in Europe and non-catastrophe exposed property coverages.

4

 
  The  profitability  of  our  reinsurance  segment  improved  in  2018,  despite  industry-wide  overcapacity  in  most 

product lines and continued weak pricing in many lines. Average rate increases for property catastrophe reinsurance 

were positive, but below expectations during the January 2019 renewals. We remain agile in our approach to the 

reinsurance market, allowing us to deliver more solutions to our clients, more quickly than our competitors. We 

reduced our participation in large, commoditized risks and continue to seek attractive opportunities.

  Mortgage insurance and reinsurance: Mortgage insurance and reinsurance was our most profitable segment in 
2018 and represented 24% of the Company’s premium volume. Net premiums written were $1.16 billion for the 

year,  increasing  4.2%  from  2017,  as  we  continued  to  allocate  additional  capital  to  this  segment. The  mortgage 

business  remains  very  attractive  because  of  desirable  market  conditions,  the  visibility  and  sustainability  of  its 

earnings  and  the  low  historical  correlation  of  returns  in  mortgage  insurance  to  returns  in  property  casualty 

insurance and reinsurance. As a result, we continued to grow our mortgage insurance in force (the aggregate dollar 

amount of each insured mortgage loan’s current principal balance) to $384 billion at the end of 2018, from $352 

billion a year earlier. Insurance in force represents a source of future income as insurance premiums are typically 

paid monthly over the period of coverage.

  We are an innovator in mortgage credit risk, as demonstrated by our 2018 launch of Arch Mortgage Risk Transfer. 

This unit is engaged in pilot programs to accept mortgage-related risks from both Fannie Mae and Freddie Mac 

and arrange the transfer of that risk to a panel of approved reinsurance capital providers. The goal is to attract a 

diversified and robust capital base to the U.S. housing market and, in doing so, support market stability through 

economic cycles. 

Managing Third-Party Capital

  We  have  been  intentionally  building  a  third-party  management  capability—that  is,  using  our  underwriting 

platform to generate income by managing risk for others. Insurers and reinsurers are evolving from being risk takers 

exclusively toward newer models where they manage risk for others or utilize pass-through entities to keep some 

risk on their balance sheets and pass along the rest to the capital markets.

  We have had great success in our mortgage insurance segment by sharing risk with the capital markets through a 

series of mortgage insurance-linked securities transactions issued through the Bellemeade special purpose vehicle, 

including three transactions in 2018. Since the inception of the program, these Bellemeade transactions have raised 

nearly $2.5 billion of reinsurance protection for loans representing over $220 billion of unpaid principal balance.

  Other  examples  include  our  ownership  position  in  Premia  Holdings  Ltd.,  formed  in  2017  to  provide  runoff 

solutions for property casualty insurance and reinsurance companies, and our multi-year agreement in 2018 with a 

major European reinsurer to provide mortgage credit assessment and underwriting advisory services related to that 

company’s involvement in credit risk transfer programs offered by Fannie Mae and Freddie Mac.

5

Strong Balance Sheet

  The Company has a healthy, liquid balance sheet with a 22.5% ratio of debt and hybrids to total capital at the 

end of 2018, down from 26.4% a year earlier, as we repaid the remaining balance of our revolving line of credit. 

A  strong  capital  position  underpins  our  ability  to  write  insurance,  serve  clients  and  quickly  adapt  to  business 

opportunities as they arise.

  We have consistently maintained that we are stewards of the capital entrusted to us and seek to create value for 

shareholders  by  deploying  this  capital  profitably  in  the  business. Whenever  the  Company  has  excess  capital  not 

needed in the business, we look to return the excess to Arch shareholders, its rightful owners. One way we do so 

is  by  repurchasing Arch  common  shares  in  the  open  market.  In  2018,  we  repurchased  10.6  million  shares  for  a 

total of $282.8 million, or an average price of $26.78 per share. At year-end, $163.7 million was available for share 

repurchases under the Board of Directors’ authorization. 

Arch People

  Our  success  in  the  highly  competitive  world  of  insurance  and  reinsurance  depends  on  an  ability  to  attract 

and  retain  talented  people  who  fit  well  with  our  culture  of  teamwork,  accountability  and  innovation;  provide 

opportunities  for  them  to  develop  their  skills  and  advance  in  their  careers;  and  reward  them  well  for  long-term 

performance. We pride ourselves on our deep pool of skilled, motivated people and our track record of promoting 

from within.

Board of Directors

  We are pleased to note the election of Laurie S. Goodman to the Arch Board of Directors at the Annual Meeting 

of Shareholders in May. Laurie is the founder and Co-Director of the nonprofit Housing Finance Policy Center at 

the Urban Institute. She brings a wealth of insight and experience to our Board, not only in her current work at the 

Urban Institute, which she joined in 2013, but also in three prior decades at Wall Street firms.

  Yiorgos Lillikas, a member of our Board since 2010, has elected not to stand for re-election at the 2019 annual 

meeting because of new professional responsibilities. We appreciate his involvement as a member of our Board and 

thank him for his contributions to the Company.

Summary

  Taken  together,  2017  and  2018  produced  extreme  property  casualty  insured  losses.  Despite  these  challenging 

market conditions, we grew our book value per share for the 10th consecutive year and generated increased earnings 

in 2018 through the diversity of our product lines and our ability to allocate capital to the best opportunities.

  Five  values  help  distinguish  what  Arch  is  and  what  it  stands  for:  work  hard  and  smart  to  serve  all  of  our 

stakeholders;  embrace  the  power  of  teamwork;  continually  pursue  innovation  and  improvement;  exhibit  honesty 

and integrity in all we do; and strive to make a difference in our communities. With our culture of innovation and 

excellence, and our proven history of underwriting discipline across a diverse portfolio of businesses, we remain 

confident in the Company’s future.

  We  thank  Arch  employees  for  their  dedication  to  the  Company  and  their  indispensable  contributions  to  its 

success. We thank our agents and brokers for their ongoing support, and our customers for choosing to do business 

with us. We recognize that our customers have other choices and it is incumbent upon us to continue to serve their 

needs with the highest quality decisions, products and experiences. And we thank you, our investors, for the trust 

you have placed in us through your ownership of our stock.

Cautionary Note Regarding Forward-Looking Statements 

The Private Securities Litigation Reform Act of 1995 (“PSLRA”) provides a “safe harbor” for forward-looking statements. This 
report or any other written or oral statements made by or on behalf of us may include forward-looking statements, which reflect 
our current views with respect to future events and financial performance. All statements other than statements of historical fact 
included in or incorporated by reference in this report are forward-looking statements. Forward-looking statements, for purposes 
of the PSLRA or otherwise, can generally be identified by the use of forward-looking terminology such as “may,” “will,” “expect,” 
“intend,” “estimate,” “anticipate,” “believe” or “continue” and similar statements of a future or forward-looking nature or their 
negative or variations or similar terminology.

Forward-looking  statements  involve  our  current  assessment  of  risks  and  uncertainties. Actual  events  and  results  may  differ 
materially from those expressed or implied in these statements. Important factors that could cause actual events or results to differ 
materially from those indicated in such statements are discussed below, elsewhere in this report and in our periodic reports filed 
with the Securities and Exchange Commission (“SEC”), and include:

•  our ability to successfully implement our business strategy during “soft” as well as “hard” markets;

•  acceptance of our business strategy, security and financial condition by rating agencies and regulators, as well as by brokers 

and our insureds and reinsureds;

• 

the integration of any businesses we have acquired or may acquire into our existing operations;

•  our ability to maintain or improve our ratings, which may be affected by our ability to raise additional equity or debt financings, 

by ratings agencies’ existing or new policies and practices, as well as other factors described herein;

•  general economic and market conditions (including inflation, interest rates, unemployment, housing prices, foreign currency 
exchange rates, prevailing credit terms and the depth and duration of a recession) and conditions specific to the reinsurance 
and insurance markets (including the length and magnitude of the current “soft” market) in which we operate;

•  competition,  including  increased  competition,  on  the  basis  of  pricing,  capacity  (including  alternative  sources  of  capital), 

coverage terms, or other factors;

•  developments in the world’s financial and capital markets and our access to such markets;

•  our  ability  to  successfully  enhance,  integrate  and  maintain  operating  procedures  (including  information  technology)  to 

effectively support our current and new business;

• 

the loss of key personnel;

•  accuracy of those estimates and judgments utilized in the preparation of our financial statements, including those related to 
revenue recognition, insurance and other reserves, reinsurance recoverables, investment valuations, intangible assets, bad debts, 
income taxes, contingencies and litigation, and any determination to use the deposit method of accounting, which for a relatively 
new insurance and reinsurance company, like our company, are even more difficult to make than those made in a mature 
company since relatively limited historical information has been reported to us through December 31, 2018;

•  greater than expected loss ratios on business written by us and adverse development on claim and/or claim expense liabilities 

related to business written by our insurance and reinsurance subsidiaries;

•  severity and/or frequency of losses;

•  claims for natural or man-made catastrophic events or severe economic events in our insurance, reinsurance and mortgage 

businesses could cause large losses and substantial volatility in our results of operations;

• 

the effect of climate change on our business;

•  acts of terrorism, political unrest and other hostilities or other unforecasted and unpredictable events;

•  availability to us of reinsurance to manage our gross and net exposures and the cost of such reinsurance;

• 

• 

the failure of reinsurers, managing general agents, third party administrators or others to meet their obligations to us;

the timing of loss payments being faster or the receipt of reinsurance recoverables being slower than anticipated by us;

•  our investment performance, including legislative or regulatory developments that may adversely affect the fair value of our 

investments;

•  changes  in  general  economic  conditions,  including  new  or  continued  sovereign  debt  concerns  in  Eurozone  countries  or 
downgrades of U.S. securities by credit rating agencies, which could affect our business, financial condition and results of 
operations;

• 

the volatility of our shareholders’ equity from foreign currency fluctuations, which could increase due to us not matching 
portions of our projected liabilities in foreign currencies with investments in the same currencies;

•  changes in accounting principles or policies or in our application of such accounting principles or policies;

•  changes in the political environment of certain countries in which we operate or underwrite business;

•  a disruption caused by cyber-attacks or other technology breaches or failures on us or our business partners and service providers, 

which could negatively impact our business and/or expose us to litigation;

•  statutory or regulatory developments, including as to tax matters and insurance and other regulatory matters such as the adoption 
of proposed legislation that would affect Bermuda-headquartered companies and/or Bermuda-based insurers or reinsurers and/
or changes in regulations or tax laws applicable to us, our subsidiaries, brokers or customers, including the recently enacted 
Tax Cuts and Jobs Act of 2017; and

• 

the other matters set forth under Item 1A “Risk Factors,” Item 7 “Management’s Discussion and Analysis of Financial Condition 
and Results of Operations” and other sections of this Annual Report on Form 10-K, as well as the other factors set forth in Arch 
Capital Group Ltd.’s other documents on file with the SEC, and management’s response to any of the aforementioned factors.  

All subsequent written and oral forward-looking statements attributable to us or persons acting on our behalf are expressly qualified 
in their entirety by these cautionary statements. The foregoing review of important factors should not be construed as exhaustive 
and should be read in conjunction with other cautionary statements that are included herein or elsewhere. We undertake no obligation 
to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise.

OUR COMPANY

General

Arch Capital, a Bermuda public limited liability company with 
$11.17  billion  in  capital  at  December 31,  2018,  provides 
insurance, reinsurance and mortgage insurance on a 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 2018, we wrote 
$5.35 billion of net premiums and reported net income available 
to Arch common shareholders of $713.6 million. Book value 
per  share  was  $21.52  at  December 31,  2018,  compared  to 
$20.30 per share at December 31, 2017.

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  executive  offices 
are  located  at Waterloo  House,  Ground  Floor,  100  Pitts  Bay

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. Since that time, we 

have  attracted  a  proven  management  team  with  extensive 
industry  experience  and  enhanced  our  existing  global 
underwriting  platform  for  our  insurance  and  reinsurance 
businesses. It is our belief that our underwriting platform, our 
experienced management team and our strong capital base that 
is unencumbered by significant pre-2002 risks have enabled us 
to  establish  a  strong  presence  in  the  global  insurance  and 
reinsurance markets.

Prior  to  the  2001  underwriting  initiative,  our  insurance 
underwriting platform consisted of Arch Insurance (Bermuda), 
a division of Arch Reinsurance Ltd. (“Arch Re Bermuda”), our 
Bermuda-based  reinsurer  and  insurer,  and  our  U.S.-licensed 
insurers, Arch Insurance Company (“Arch Insurance”), Arch 
Excess &  Surplus  Insurance  Company  (“Arch  E&S”), Arch 
Specialty  Insurance  Company  (“Arch  Specialty”)  and Arch 
Indemnity  Insurance  Company  (“Arch  Indemnity”).  We 
established Arch Insurance Company (Europe) Limited (“Arch 
Insurance  Company  Europe”),  our  United  Kingdom-based 
subsidiary,  in  2004,  and  we  expanded  our  North American 
presence  when  Arch  Insurance  opened  a  branch  office  in 
Canada in 2005. In 2013, Arch Insurance Canada Ltd. (“Arch 
Insurance Canada”), a Canada domestic company, commenced 
operations  and  replaced  the  branch  office.  In  2009,  we 
established  a  managing  agent  and  syndicate  2012  (“Arch 
Syndicate  2012”)  at  Lloyd’s  of  London  (“Lloyd’s”).  In 
December 2018, we completed the acquisition of McNeil & 
Company,  Inc.  (“McNeil”),  a  U.S.  nationwide  leader  in 
specialized  risk  management  and  program  administration 
headquartered in Cortland, New York. In addition, we acquired 
U.K.  commercial  lines  business  from  Ardonagh  Group  in 
January  2019.  See  “Operations—Insurance  Operations”  for 
further details on our insurance operations.

Prior  to  the  2001  underwriting  initiative,  our  reinsurance 
underwriting platform consisted of Arch Re Bermuda and Arch 
Reinsurance  Company  (“Arch  Re  U.S.”),  our  U.S.-licensed 
reinsurer. Our reinsurance operations in Europe began in 2006 
with the formation of a Swiss branch of Arch Re Bermuda, and 
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, which replaced the Swiss 
branch. We launched treaty operations in Canada in 2011 and 
the following year we acquired the credit and surety reinsurance 
operations  of Ariel  Reinsurance  Company  Ltd.  In  2015,  we 

ARCH CAPITAL

obtained  complete  ownership  and  effective  control  of  Gulf 
Reinsurance Limited (“Gulf Re”), previously a joint venture. 
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.  Our  mortgage  platform  was 
built  through  the  acquisition  of  CMG  Mortgage  Insurance 
Company  in  2014  (subsequently  renamed  Arch  Mortgage 
Insurance  Company)  and  further  expanded  through  the 
acquisition  of  United  Guaranty  Corporation 
(“UGC”) 
(including United Guaranty Residential Insurance Company), 
from  American  International  Group,  Inc.  (“AIG”),  which 
closed at the end of 2016. In 2017, we completed the acquisition 
of AIG United Guaranty Insurance (Asia) Limited (renamed 
“Arch MI Asia Limited”) from AIG.

Our  U.S.  primary  mortgage  operations  provide  mortgage 
insurance  products  and  services  to  the  U.S.  market.  These 
operations include providers that 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.  Arch  Mortgage  Insurance 
Designated Activity Company (“Arch MI Europe”), provides 
mortgage  insurance  products  and  services  to  the  European 
market. In January 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.

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 along with mortgage reinsurance for the U.S. 
and  Australian  markets.  See 
“Operations—Mortgage 
Operations” for further details on our mortgage operations.

In 2014 we acquired approximately 11% of Watford Holdings 
Ltd. Watford Holdings Ltd. is the parent of Watford Re Ltd., a 
multi-line  Bermuda  reinsurance  company  (together  with 
Watford Holdings Ltd., “Watford Re”). In 2017, we acquired 
approximately 25% of Premia Holdings Ltd. Premia Holdings 
Ltd.  is  the  parent  of  Premia  Reinsurance  Ltd.,  a  multi-line 
Bermuda reinsurance company (together with Premia Holdings 
Ltd., “Premia Re”). See “Operations—Other Operations” for 
further details on Watford Re and Premia Re.

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, 2019. Since the inception of the share repurchase 

program in February 2007 through December 31, 2018, Arch 
Capital has repurchased 386.2 million common shares for an 
aggregate  purchase  price  of  $3.97  billion. At  December 31, 
2018,  the  total  remaining  authorization  under  the  share 
repurchase program was $163.7 million.

OPERATIONS

We classify our businesses into three underwriting segments — 
insurance, reinsurance and mortgage — and two other operating 
segments — ‘other’ and corporate (non-underwriting). For an 
analysis  of  our  underwriting  results  by  segment,  see  note  4,

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:

business  with 

•  Capitalize on profitable underwriting opportunities. Our 
insurance group believes that its experienced management 
and  underwriting  teams  are  positioned  to  locate  and 
identify 
risk/reward 
characteristics. As  profitable  underwriting  opportunities 
are identified, our insurance group will continue to seek to 
make  additions  to  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.

attractive 

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 
the 
group’s  senior  management  closely  monitors 
underwriting process.

•  Focus  on  providing  superior  claims  management.  Our 
insurance group believes that claims handling is an integral 
component  of  credibility  in  the  market  for  insurance 
products. Therefore, our insurance group believes that its 
ability to handle claims expeditiously and satisfactorily is 
a  key  to  its  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.  Our  insurance  group 
works with select international, national and regional retail 
and  wholesale  brokers  and  leading  managing  general 
agencies,  including  McNeil,  to  distribute  our  insurance 
products.

•  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 
to niche opportunities, quality scalable businesses, or lines 
with reliable defensive qualities. 

Our insurance group writes business on both an admitted and 
non-admitted  basis.  Our  insurance  group  focuses  on  the 
following areas:

•  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 
four regional offices, and the executive in charge of each 
region  is  primarily  responsible  for  all  aspects  of  the 
marketing  and  distribution  of  our  insurance  group’s 
products, including the management of broker and other 
producer  relationships  in  such  executive’s  respective 
region.  In  our  non-U.S.  offices,  a  similar  philosophy  is 

•  Construction and national accounts: primary and excess 
casualty  coverages  to  middle  and  large  accounts  in  the 
construction  industry  and  a  wide  range  of  products  for 
middle  and  large  national  accounts,  specializing  in  loss 
sensitive primary casualty insurance programs (including 
large deductible, self-insured retention and retrospectively 
rated programs).

•  Excess and surplus casualty: primary and excess casualty 
insurance  coverages,  including  middle  market  energy 
business, and contract binding, which primarily provides 
casualty coverage through a network of appointed agents 
to small and medium risks.

• 

Lenders products: collateral protection, debt cancellation 
and  service  contract  reimbursement  products  to  banks, 

ARCH CAPITAL

2018 FORM 10-K

credit  unions,  automotive  dealerships  and  original 
equipment  manufacturers  and  other  specialty  programs 
that pertain to automotive lending and leasing.

•  Professional lines: directors’ and officers’ liability, errors 
and  omissions  liability,  employment  practices  liability, 
fiduciary liability, crime, professional indemnity and other 
financial related coverages for corporate, private equity, 
venture  capital,  real  estate  investment  trust,  limited 
partnership, financial institution and not-for-profit clients 
of all sizes and medical professional and general liability 
insurance  coverages  for  the  healthcare  industry.  The 
business is predominately written on a claims-made basis.

•  Programs:  primarily  package  policies,  underwriting 
workers’ compensation and umbrella liability business in 
support of desirable package programs, targeting program 
managers  with  unique  expertise  and  niche  products 
offering general liability, commercial automobile, inland 
marine  and  property  business  with  minimal  catastrophe 
exposure.

•  Property, energy, marine and aviation: primary and excess 
including 
insurance 
general  property 
catastrophe-exposed  property  coverage,  for  commercial 
clients. Coverages for marine include hull, war, specie and 
liability.  Aviation  and  stand-alone  terrorism  are  also 
offered.

coverages, 

• 

Travel, accident and health: specialty travel and accident 
and  related  insurance  products  for  individual,  group 
travelers, travel agents and suppliers, as well as accident 
and health, which provides accident, disability and medical 
plan  insurance  coverages  for  employer  groups,  medical 
plan members, students and other participant groups.

•  Other: includes alternative market risks (including captive 
insurance programs), excess workers’ compensation and 
employer’s liability insurance coverages for qualified self-
insured groups, associations and trusts, statutory Defense 
Base Act workers compensation and employers liability, 
and contract and commercial surety coverages, including 
contract  bonds  (payment  and  performance  bonds) 
primarily  for  medium  and 
large  contractors  and 
commercial surety bonds for Fortune 1000 companies and 
smaller transaction business programs.

Underwriting Philosophy. Our insurance 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  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. In the past, 
our insurance group also entered 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.  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 
due diligence financial and operational 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 
Company—We could be materially adversely affected to the 
extent that managing general agents, general agents and other 
producers exceed their underwriting authorities or if our agents, 
our insureds or other third parties commit fraud or otherwise 
breach  obligations  owed  to  us.”  For  information  on  major 
brokers,  see  note  16,  “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

ongoing qualitative and quantitative assessments of reinsurers, 
including  a  review  of  the  financial  stability,  appropriate 
licensing, reputation, claims paying ability and underwriting

risk  management  policies, 

For  catastrophe-exposed  insurance  business,  our  insurance 
group  seeks  to  limit  the  amount  of  exposure  to  catastrophic 
losses it assumes through a combination of managing aggregate 
limits,  underwriting  guidelines  and  reinsurance.  For  a 
discussion  of  our 
see 
“Management’s  Discussion  and  Analysis  of  Financial 
Condition  and  Results  of  Operations—Critical  Accounting 
Policies, Estimates and Recent Accounting Pronouncements—
Ceded Reinsurance” and “Risk Factors—Risks Relating to Our 
Industry—The failure of any of the loss limitation methods we 
employ could have a material adverse effect on our financial 
condition or results of operations.”

Claims  Management.  Our 
insurance  group’s  claims 
management function is performed by claims professionals, as 
well  as  experienced  external  claims  managers  (third  party 
administrators), where appropriate. In addition to investigating, 
evaluating  and  resolving  claims,  members  of  our  insurance 
group’s  claims  departments  work  with  underwriting 
professionals as functional teams in order to develop products 
and services desired by the group’s clients.

Reinsurance Operations

Our reinsurance operations are conducted on a worldwide basis 
through our reinsurance subsidiaries, Arch Re Bermuda, Arch 
Re U.S. and Arch Re Europe. Arch Re Bermuda is a registered 
Class 4 insurer and long-term insurer and is headquartered in 
Hamilton, Bermuda. Arch Re U.S. is licensed or is an accredited 
or  otherwise  approved  reinsurer  in  50  states,  the  District  of 
Columbia  and  Puerto  Rico,  the  provinces  of  Ontario  and 
Quebec in Canada with its principal U.S. offices in Morristown, 
New Jersey. Treaty operations in Canada are conducted through 
the Canadian branch of Arch Re U.S. (“Arch Re Canada”). Arch 
Re  U.S.  is  also  an  admitted  insurer  in  Guam.  Our  property 
facultative  reinsurance  operations  are  conducted  primarily 
through Arch  Re  U.S.  The  property  facultative  reinsurance 
operations  have  offices  throughout  the  U.S.,  Canada  and  in 
Europe. Arch Re Europe, licensed and authorized as a non-life 
reinsurer and a life reinsurer, is headquartered in Dublin, Ireland 
with branch offices in Zurich and London.

In February 2017, Arch Underwriters (Gulf) Limited (“Arch 
Underwriters Gulf”) was licensed as an Insurance Manager by 

the  Dubai  Financial  Services  Authority.  Arch  Underwriters 
Gulf is based in the Dubai International Financial Centre and 
provides underwriting, administrative and support services to 
Arch  Re  Bermuda  and  certain  employees  and  certain 
administrative support services to Gulf Re.

Strategy. Our reinsurance group’s strategy is to capitalize on 
our 
financial  capacity,  experienced  management  and 
operational flexibility to offer multiple products through our 
operations. The reinsurance group’s operating principles are to:

•  Actively select and manage risks. Our reinsurance group 
only underwrites business that meets certain profitability 
criteria, and it emphasizes disciplined underwriting over 
premium  growth.  To  this  end,  our  reinsurance  group 
maintains 
reinsurance 
centralized 
underwriting guidelines and authorities.

control 

over 

•  Maintain  flexibility  and  respond  to  changing  market 
reinsurance  group’s  organizational 
conditions.  Our 
structure  and  philosophy  allows  it  to  take  advantage  of 
increases or changes in demand or favorable pricing trends. 
Our reinsurance group believes that its existing platforms 
in Bermuda, the U.S., Europe, Dubai and Canada, broad 
underwriting  expertise  and  substantial  capital  facilitate 
adjustments to its mix of business geographically and by 
line and type of coverage. Our reinsurance group believes 
that this flexibility allows it to participate in those market 
opportunities  that  provide  the  greatest  potential  for 
underwriting profitability.

•  Maintain  a  low  cost  structure.  Our  reinsurance  group 
believes that maintaining tight control over its staffing level 
and  operating  primarily  as  a  broker  market  reinsurer 
permits it to maintain low operating costs relative to its 
capital and premiums.

Our reinsurance group writes business on both a proportional 
and  non-proportional  basis  and  writes  both  treaty  and 
facultative business. In a proportional 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,  assessments  and 
miscellaneous 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.

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, 
such as property catastrophe and casualty clash, the reinsurance 
group’s treaty operations participate in a 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 companies for individual risks 
not covered by their reinsurance treaties, for unusual risks or 
for amounts in excess of the limits on their reinsurance treaties.

Our reinsurance group focuses on the following areas:

•  Casualty: provides coverage to ceding company clients on 
third party liability and workers’ compensation exposures 
from ceding company clients, primarily on a treaty basis. 
Exposures  include,  among  others,  executive  assurance, 
professional liability, workers’ compensation, excess and 
umbrella liability, excess motor and healthcare business.

•  Marine and aviation: provides coverage for energy, hull, 
cargo, specie, liability and transit, and aviation business, 
including  airline  and  general  aviation  risks.  Business 
written may also include space business, which includes 
coverages for satellite assembly, launch and operation for 
commercial space programs.

•  Other  specialty:  provides  coverage  to  ceding  company 
clients for proportional motor and other lines, including 
surety,  accident  and  health,  workers’  compensation 
catastrophe, agriculture, trade credit and political risk.

•  Property  catastrophe:  provides  protection  for  most 
catastrophic  losses  that  are  covered  in  the  underlying 
policies  written  by  reinsureds,  including  hurricane, 
earthquake, flood, tornado, hail and fire, and coverage for 
other perils on a case-by-case basis. Property catastrophe 
reinsurance provides coverage on an excess of loss basis 
when aggregate losses and loss adjustment expense from 
a single occurrence or aggregation of losses from a covered 
peril exceed the retention specified in the contract.

•  Property  excluding  property  catastrophe:  provides 
coverage for both personal lines and commercial property 
exposures  and  principally  covers  buildings,  structures, 
equipment and contents. The primary perils in this business 
include  fire,  explosion,  collapse,  riot,  vandalism,  wind, 
tornado, flood and earthquake. Business is assumed on both 
a  proportional  and  excess  of  loss  basis.  In  addition, 
facultative business is written which focuses on individual 
commercial property risks on an excess of loss basis.

•  Other.  includes  life  reinsurance  business  on  both  a 
proportional  and  non-proportional  basis,  casualty  clash 

business and, in limited instances, non-traditional business 
which is intended to provide insurers with risk management 
solutions that complement traditional reinsurance. 

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

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

• 

• 

• 

• 

• 

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

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

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

projections of future loss frequency and severity; and 

the perceived financial strength of the cedent. 

Marketing.  Our  reinsurance  group  generally  markets  its 
reinsurance  products  through  brokers,  except  our  property 
facultative reinsurance group, which generally deals directly 
with the ceding companies. Brokers do not have the authority 
to  bind  our  reinsurance  group  with  respect  to  reinsurance 
agreements, nor does our reinsurance group commit in advance 
to  accept  any  portion  of  the  business  that  brokers  submit  to 
them. Our reinsurance group generally pays brokerage fees to 
brokers  based  on  negotiated  percentages  of  the  premiums 
written through such brokers. For information on major brokers, 
see  note  16, 
and  Contingencies—
Concentrations of Credit Risk,” to our consolidated financial 
statements in Item 8.

“Commitments 

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

its  net  appetite  for  risk.  See  note  7,  “Reinsurance,”  to  our 
consolidated financial statements in Item 8.

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

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

Mortgage Operations

Our  mortgage  operations  provide  U.S.  and  international 
mortgage  insurance  and  reinsurance  operations  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  and 
United  Guaranty  Residential  Insurance  Company  (together, 
“Arch MI U.S.”); mortgage reinsurance primarily through Arch 
Re Bermuda to mortgage insurers on both a proportional and 
non-proportional basis globally; direct mortgage insurance in 
Europe through Arch MI Europe and in Hong Kong through 
Arch MI Asia Limited (“Arch MI Asia”); and participation in 
various  GSE  credit  risk-sharing  products  primarily  through  
Arch Re Bermuda.

In  2014  we  completed  the  acquisition  of  CMG  Mortgage 
Insurance Company from its owners, PMI Mortgage Insurance 
Co.,  (“PMI”)  and  CMFG  Life  Insurance  Company  (“CUNA 
Mutual”) and acquired PMI’s mortgage insurance platform and 
related  assets.  CMG  Mortgage  Insurance  Company  was 
renamed “Arch Mortgage Insurance Company” and entered the 
U.S.  mortgage 
insurance  marketplace.  Arch  Mortgage 
Insurance Company is licensed and operates in all 50 states, the 
District of Columbia and Puerto Rico.

On December 31, 2016, we completed the acquisition of UGC 
and  its  primary  operating  subsidiary,  United  Guaranty 
Residential Insurance Company, which is licensed and operates 
in all 50 states and the District of Columbia. 

Arch  Mortgage  Insurance  Company  and  United  Guaranty 
Residential Insurance Company have each been approved as an 
eligible  mortgage  insurer  by  Fannie  Mae  and  Freddie  Mac, 
subject to maintaining certain ongoing requirements (“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.

Arch MI Europe was licensed and authorized by the Central 
Bank of Ireland (“CBOI”) in 2011 to operate on a pan-European 
basis under the European Freedom of Services Act. Arch MI 
Europe is headquartered in Dublin, Ireland. Arch Underwriters 
Europe  Limited  (“Arch  Underwriters  Europe”),  an  Irish 
insurance  and  reinsurance 
company  authorized  as  an 
intermediary by the CBOI, acts on behalf of Arch MI Europe 
and Arch Re Europe with branch offices in Italy, Switzerland, 
the U.K., and Finland. In 2017 we completed the acquisition of 
Arch MI Asia from AIG. On January 17, 2019, Arch LMI was 
authorized by APRA to write lenders’ mortgage insurance. Arch 
LMI is headquartered in Sydney, Australia and will focus on 
providing direct lenders’ mortgage insurance 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:

•  Capitalize on profitable underwriting opportunities. Our 
mortgage group believes that its experienced management, 
analytics and underwriting teams are positioned to identify 
risk/reward 
and  evaluate  business  with  attractive 
characteristics.

•  Maintain  a  disciplined  credit  risk  philosophy.  Our 
mortgage  group’s  credit  risk  philosophy  is  to  generate 
underwriting profit through disciplined credit risk analysis 
and proper pricing. Our mortgage group believes that the 
key to this approach is maintaining discipline across all 
phases  of  the  applicable  housing  and  mortgage  lending 
cycles.

•  Provide superior and innovative mortgage products and 
services. Our mortgage group believes that it can leverage

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

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. 

•  Maintain  our  position  as  a  leading  provider  of  U.S. 
mortgage 
to  our  2014 
insurance  business.  Prior 
acquisition, Arch Mortgage Insurance Company was the 
leading  provider  of  mortgage  insurance  products  and 
services  to  credit  unions  in  the  U.S.  We  broadened  our 
customer  base  into  national  and  regional  banks  and 
mortgage originators while maintaining and increasing its 
share of the mortgage insurance credit union market. With 
the acquisition of UGC, a leading provider of mortgage 
insurance products and services to national and regional 
banks  and  mortgage  originators,  we  are  the  leading 
provider of U.S. mortgage insurance.

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 
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.

it 

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 

•  Direct mortgage insurance in Europe and other countries 
where we identify profitable underwriting opportunities. 
Since  2011,  Arch  MI  Europe  has  offered  mortgage 
insurance  to  European  mortgage  lenders.  Arch  MI 
Europe’s  mortgage  insurance  is  primarily  purchased  by 
European  mortgage  lenders  in  order  to  reduce  lenders’ 
credit risk and regulatory capital requirements associated 
with the insured mortgages. In certain European countries, 
lenders  purchase  mortgage

regulatory compliance with respect to high loan-to-value 
residential  lending.  Arch  MI  Europe  offers  mortgage 
insurance on both a “flow” basis to cover new originations 
and through structured transactions to cover one or more 
portfolios  of  previously  originated  residential  loans.  In 
addition, with our acquisition of Arch MI Asia in 2017 and 
regulatory approval of Arch LMI in January 2019, we are 
focused on expanding origination opportunities for lenders 
in Hong Kong and throughout Asia and Australia.

•  Reinsurance.  Arch  Re  Bermuda  provides  quota  share 
reinsurance  covering  U.S.  and  international  mortgages. 
Such amounts include a quota share reinsurance agreement 
with  PMI  pursuant  to  which  it  agreed  to  provide  100% 
quota  share  indemnity  reinsurance  to  PMI  for  all 
certificates  of  insurance  that  were  issued  by  PMI  from 
January 1, 2009 through December 31, 2011 that were not 
in default as of an agreed upon effective date. Other than 
this  quota  share,  no  PMI  legacy  mortgage  insurance 
exposures were assumed.

•  Other credit risk-sharing products. In addition to providing 
traditional mortgage insurance and reinsurance, we offer 
various  credit  risk-sharing  products  to  government 
agencies and mortgage lenders. The GSEs have reduced 
their exposure to mortgage risk and continue to shift more 
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 
risk sharing programs.

In 2017, we established Arch Mortgage Risk Transfer PCC Inc. 
(“Arch  MRT”)  a  District  of  Columbia  based  protected  cell 
captive insurer, licensed by District of Columbia Department 
of  Insurance,  Securities  and  Banking  as  a  mortgage  insurer. 
Arch  MRT  issues  direct  mortgage  insurance  to  the  GSEs

through incorporated protected cells and cedes 100% of the risk 
to GSE approved reinsurers, including Arch Re U.S. Arch MRT 
entered into one pilot transaction with each of the GSEs in 2018.

In  2018  we  established  Arch  Credit  Risk  Services  Inc.
(“ACRS”)  and  licensed  it  as  a  reinsurance  intermediary  in 
several  states. ACRS  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 
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.  We  employ  a  sales  force  located 
throughout the U.S. 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  (including  branches  and  affiliates)  accounted  for 
6.9% of our primary new insurance written during 2018 with 
no  other  customer  accounting  for  greater  than  3.4%.  The 
percentage of our primary new insurance written generated by 
our  top  10  customers  was  25.2%  in  2018.  In  Europe, Asia, 
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. For 

a  discussion  of  our 
risk  management  policies,  see 
“Management’s  Discussion  and  Analysis  of  Financial 
Condition  and  Results  of  Operations—Critical  Accounting 
Policies, Estimates and Recent Accounting Pronouncements—
Ceded Reinsurance” and “Risk Factors—Risks Relating to Our 
Industry—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 7, 
“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 
the  agreements,  our  mortgage 
their  obligations  under 
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 becomes two consecutive monthly 
payments in default. Borrowers default for a variety of reasons, 
including  a  reduction  of  income,  unemployment,  divorce, 
illness, inability to manage credit, rising interest rate levels and 
declining home prices. Upon notice of a default, in certain cases 
we may coordinate with loan servicers to facilitate and enhance 
retention  workouts  on  insured  loans.  Retention  workouts 
include loan modifications and other loan repayment options, 
which  may  enable  borrowers  to  cure  mortgage  defaults  and 
retain ownership of their homes. If a retention workout is not 
viable  for  a  borrower,  our  loss  on  a  loan  may  be  mitigated 
through  a  liquidation  workout  option,  including  a  pre-
foreclosure sale or a deed-in-lieu of foreclosure. 

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

• 

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

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

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

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

Other Operations

In  2014  we  and  HPS  Investment  Partners,  LLC  (formerly 
Highbridge Principal Strategies, LLC) (“HPS”), sponsored the 
formation of Watford Re. Arch Re Bermuda invested $100.0 
million and acquired 2,500,000 common shares, approximately 
11%, of Watford Re and a warrant to purchase up to 975,503 
additional common shares. Watford Re’s strategy is to combine 
a  diversified  reinsurance  and  insurance  business  with  a 
disciplined  investment  strategy  comprised  primarily  of  non-
investment  grade  credit  assets.  Watford  Re  has  its  own 
management and board of directors and is responsible for the 
overall  profitability  of  its  results.  Arch  Re  Bermuda  has 
appointed two directors to serve on the nine person board of 
directors of Watford Re. We performed an analysis of Watford 
Re and concluded that Watford Re is a variable interest entity 
and that we are the primary beneficiary of Watford Re. As such, 
100%  of  the  results  of  Watford  Re  are  included  in  our 
consolidated financial statements.

In 2017 we and Kelso & Company (“Kelso”) sponsored the 
formation of Premia Re. Premia Re’s strategy is to reinsure or 
acquire companies or 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 Re as well 
as warrants to purchase additional common equity. Affiliates of 
Kelso  invested  $300.0  million  and  acquired  the  balance  of 
Premia Re as well as warrants to purchase additional common 
equity. Arch Re Bermuda is providing a 25% whole account 
quota share reinsurance treaty on business written by Premia 
Re,  and  subsidiaries  of  Arch  Capital  are  providing  certain 
administrative and support services to Premia Re, in each case 
pursuant to separate multi-year agreements.  Arch Re Bermuda 
has appointed two directors to serve on the seven person board 
of directors of Premia Re.

Employees

As  of  February  15,  2019, Arch  Capital  and  its  subsidiaries 
employed approximately 3,642 full-time employees.

RESERVES

Reserve estimates are derived after extensive consultation with 
individual  underwriters  and  claims  professionals,  actuarial 
analysis of the loss reserve development and comparison with 
industry  benchmarks.  Our  reserves  are  established  and 
reviewed by experienced internal actuaries. Generally, reserves 
are established without regard to whether we may subsequently 
contest the claim. We do not currently discount our loss reserves 
except  for  excess  workers’  compensation  and  employers’ 
liability loss reserves in our insurance operations.

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. 

In  establishing  Loss  Reserves,  including  loss  adjustment 
expenses (“LAE”), 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.  The  timing  and 
amounts of actual claim payments related to recorded reserves 
vary based on many factors including large individual losses 
and 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. 
This  may  result  in  significant  variability  in  loss  payment 
patterns and, therefore, may impact the related asset/liability 
investment management process in order to be in a position, if 
necessary,  to  make  these  payments.  See  “Management’s 
Discussion and Analysis of Financial Condition and Results of 
Operations—Critical  Accounting  Policies,  Estimates  and 
Recent Accounting Pronouncements—Reserves for Losses and 
Loss Adjustment Expenses.”

Our initial reserving method to date has to a large extent been 
the expected loss method, which is commonly applied when 
limited  loss  experience  exists. We  select  the  initial  expected 
loss and loss adjustment expense ratios based on information 
derived  by  our  underwriters  and  actuaries  during  the  initial 
pricing of the business, supplemented by industry data where 
appropriate.  These  ratios  consider,  among  other  things,  rate 
changes and changes in terms and conditions that have been 
observed in the market. Any estimates and assumptions made 
as part of the reserving process could prove to be inaccurate 
due to several factors, including the fact that relatively limited 
historical  information  has  been  reported  to  us  through

concentrated  risk  exposure  could  materially  adversely  affect 
our financial condition and results of operations. Although we 
monitor  the  financial  condition  of  our  reinsurers  and 
retrocessionaires  and  attempt  to  place  coverages  only  with 
substantial, financially sound carriers, we may not be successful 
in doing so.

December 31, 2018. We employ a number of different reserving 
methods depending on the segment, the line of business, the 
availability of historical loss experience and the stability of that 
loss experience. Over time, we have given additional weight to 
our historical loss experience in our reserving process due to 
the continuing maturation of our reserves, and the increased 
availability and credibility of the historical experience. 

For  additional  information  regarding  the  key  underlying 
movements  in  our  losses  and  loss  adjustment  expenses  by 
segment,  see  “Management’s  Discussion  and  Analysis  of 
Financial  Condition  and  Results  of  Operations—Results  of

During the 2018 second quarter a subsidiary of the Company entered into a 
retroactive reinsurance transaction with a third party reinsurer to reinsure runoff 
liabilities associated with certain discontinued U.S. specialty casualty and

Unpaid  and  paid  losses  and  loss  adjustment  expenses

2018.  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

INVESTMENTS

At  December 31,  2018,  total  investable  assets  held  by Arch 
were $19.57 billion, excluding the $2.76 billion included in the 
‘other’ segment (i.e., attributable to Watford Re). 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, 
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 future expand into areas which 
are not part of our current investment strategy.

In our U.S. mortgage business, we compete with five active 
U.S. mortgage insurers, which include the mortgage insurance 
subsidiaries  of  Essent  Group  Ltd.,  Genworth  Financial Inc., 
MGIC Investment Corporation, NMI Holdings Inc. and Radian 
Group Inc. The private mortgage insurance industry is highly 
competitive. Private mortgage insurers generally compete on 
the  basis  of  underwriting  guidelines,  pricing,  terms  and 
conditions,  financial  strength,  product  and  service  offerings, 
customer relationships, reputation, the strength of management, 
technology,  and  innovation  in  the  delivery  and  servicing  of 
insurance products. Arch MI U.S. and other private mortgage 
insurers compete with federal and state government agencies 
that  sponsor  their  own  mortgage  insurance  programs.  The 
private mortgage insurers’ principal government competitor is 
the Federal Housing Administration (“FHA”) and, to a lesser 
degree, the U.S. Department of Veterans Affairs (“VA”). Future 
changes to the FHA program may impact the demand for private 
mortgage insurance.

Arch MI U.S. and other private mortgage insurers increasingly 
compete  with  multi-line  reinsurers  and  capital  markets 
alternatives to private mortgage insurance. The GSEs continued 
their respective mortgage credit risk transfer (“CRT”) programs 
including  the  use  of  front  and  back-end  transactions  with 
multiline  reinsurers.  These  transactions  continue  to  create 
opportunities  for  multiline  property  casualty  reinsurance 
groups and capital markets participants. The ongoing expansion 
of the GSEs risk transfer programs continue to attract additional 
reinsurers into the market with approximately 40 reinsurers now 
competing for business.

For  other  U.S.  risk  sharing  products  and  non-U.S.  mortgage 
insurance  opportunities,  we  have  also  seen 
increased 
competition from well capitalized and highly rated multiline 
reinsurers. It is our expectation that the depth and capacity of 
competitors from this segment will continue to increase over 
the next several years as more residential mortgage credit risk 
is borne by private capital.

RATINGS

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 
party internationally recognized statistical rating 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 
insurance or reinsurance provider. Periodically, rating agencies 
evaluate us to confirm that we continue to meet their criteria 
for  the  ratings  assigned  to  us  by  them. A.M.  Best  Company 
(“A.M. Best”), Fitch Ratings (“Fitch”), Moody’s and S&P are 
ratings agencies which have assigned financial strength and/or 
issuer  ratings  to  Arch  Capital  and/or  one  or  more  of  its 
subsidiaries.  The  ratings  issued  on  our  companies  by  these 
agencies are announced publicly and are available directly from 
the agencies. For further information on our financial strength 
and/or  issuer  ratings,  see  “Management’s  Discussion  and 
Analysis of Financial Condition and Results of Operations—
Liquidity and Capital Resources.”

COMPETITION

The worldwide reinsurance and insurance businesses are highly 
competitive. We compete, and will continue to compete, with 
major U.S. and non-U.S. insurers and reinsurers, some of which 
have greater financial, marketing and management resources 
than we have and longer-term relationships with insureds and 
brokers than we have had. We compete with other insurers and 
reinsurers primarily on the basis of overall financial strength, 
ratings  assigned  by  independent  rating  agencies,  geographic 
scope of business, strength of client relationships, premiums 
charged, contract terms and conditions, products and services 
offered,  speed  of  claims  payment,  reputation,  employee 
experience, and qualifications and local presence.

In  our  insurance  business,  we  compete  with  insurers  that 
provide  specialty  property  and  casualty  lines  of  insurance, 
including Alleghany Corporation, American Financial Group, 
Inc.,  American  International  Group,  Inc.,  AXA  XL,  AXIS

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 planning 
process,  capital  modeling  and  allocation, 
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 for each of the 
following major risks: underwriting (insurance) risk including 
pricing,  reserving  and  catastrophe;  investment  including 
market and liquidity risks; strategic risk; group risk including 
governance and capital market risk; credit risk; and operational 
risk, including regulatory, investor relations (reputational risk), 
rating agency and outsourcing risks.

The  framework  includes  details  of  our  risk  philosophy  and 
policies  to  address  the  material  risks  confronting  us;  and 
compliance, 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.  Board  approval  is  required  for  any  new  high 
level risks or change in inherent or residual designations.

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  FIR  Committee.  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 he 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  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 FIR Committee for 
review  and  discussion  at  their  quarterly  meeting. The  report 
includes an overview of selected key risks; changes in the rating 
of  high  level  risks  in  the Arch  Capital  risk  register;  a  risk 
dashboard  that  depicts  the  status  of  risk  limit  and  tolerance 
metrics;  a  summary  of  largest  exposures  and  concentration 
risks; and our reinsurance arrangements, including outstanding 
and  uncollectible  recoveries.  If  necessary,  risk  management 
matters reviewed at the FIR Committee meeting are presented 
for  discussion  by  the  Board.  The  CRO  is  responsible  for 
immediately escalating any significant risk matters to executive 
management, the FIR 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.

Implementation and Integration. We believe that an integrated 
approach to developing, measuring and reporting our Own Risk 
and Solvency Assessment (“ORSA”) is an integral 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.  

ARCH CAPITAL

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  integral  parts  of  our 
business  strategy,

We also take the results of the ORSA into account for our system 
of  governance,  including  long-term  capital  management, 
business planning and new product development. The results 
of  the  ORSA  also  contributes  to  various  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 
in  existing 
jurisdictions  or

Bermuda

General. Our 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”). The Insurance Act imposes certain solvency and liquidity 
standards and auditing and reporting requirements and grants 
the  Bermuda  Monetary  Authority  (the  “BMA”)  powers  to 
supervise,  investigate,  require  information  and  demand  the 

production  of  documents  and  intervene  in  the  affairs  of 
insurance  companies.  Significant  requirements  include  the 
appointment of an independent auditor, the appointment of a 
loss  reserve  specialist,  the  appointment  of  a  principal 
representative  in  Bermuda,  the  filing  of  annual  Statutory 
Financial Returns, the filing of annual financial statements in 
accordance with U.S. generally accepted accounting principles 
(“GAAP”), the filing of an annual capital and solvency return, 
compliance with minimum and enhanced capital requirements, 
compliance  with  certain  restrictions  on  reductions  of  capital 
and  the  payment  of  dividends  and  distributions,  compliance 
with group solvency and supervision rules, if applicable, and 
compliance with the Insurance Code of Conduct (relating to 
corporate governance, risk management and internal controls). 

Arch Re Bermuda must also comply with a minimum liquidity 
ratio and minimum solvency margin in respect of its general 
business. The minimum liquidity ratio requires that the value 
of relevant assets must not be less than 75% of the amount of 
relevant  liabilities.  The  minimum  solvency  margin,  which 
varies depending on the class of the insurer, is determined as a 
percentage  of  either  net  reserves  for  losses  and  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 
enhanced capital requirement. While a Class 4 insurer is not 
currently required to maintain 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 which 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 

ARCH CAPITAL

18

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.

On July 30, 2018 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 information for other regulatory 
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 with other authorities, supervisory activities in respect 
of our Group; (v) coordinating any enforcement action that may 
need to be taken against our Group or any Group members; and 
(vi) coordinating meetings of colleges of supervisors in order 
to facilitate the carrying out of these functions. As Designated 
Insurer, Arch Re Bermuda is required to facilitate compliance 
by  our  Group  with  the  group  insurance  solvency  and 
supervision rules.

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

group enhanced capital requirement (“Group ECR”) and the 
BMA has established a group target capital level equal to 120% 
of the Group ECR.

The  BMA  maintains  supervision  over  the  controllers  of  all 
Bermuda registered insurers, and accordingly, any person who, 
directly or indirectly, becomes a holder of at least 10%, 20%, 
33% or 50% of our ordinary shares must notify the BMA in 
writing within 45 days of becoming such a holder (or ceasing 
to be such a holder). The BMA may object to such a person and 
require the holder to reduce its holding of ordinary shares and 
direct, among other things, that voting rights attaching to the 
ordinary shares shall not be exercisable

United States

General. Our U.S. based insurance operating subsidiaries are 
subject to extensive governmental regulation and supervision 
by  the  states  and  jurisdictions  in  which  they  are  domiciled, 
licensed and/or approved to conduct business. The insurance 
laws  and  regulations  of  the  state  of  domicile  have  the  most 
significant  impact  on  operations.  We  currently  have  U.S. 
in 
insurance  and/or  reinsurance  subsidiaries  domiciled 
Delaware, North Carolina, Missouri,Wisconsin and the District 
of  Columbia.  State  insurance  regulation  and  supervision  is 
designed  to  protect  policyholders  rather  than  investors. 
Generally,  state  regulatory  authorities  have  broad  regulatory 
powers over such matters as licenses, standards of solvency, 
premium  rates,  policy  forms,  marketing  practices,  claims 
practices,  investments,  methods  of  accounting,  form  and 
content of financial statements, certain aspects of governance, 
enterprise risk management, 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 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  Company  Europe  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 

ARCH CAPITAL

19

2018 FORM 10-K

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  and  has  obtained 
the commissioner’s prior approval. Under most states’ statutes 
acquiring 10% or more of the voting securities of an insurance 
company or its parent company is presumptively considered an 
acquisition of control of the insurance company, although such 
presumption may be rebutted. 

The  National  Association  of  Insurance  Commissioners 
(“NAIC”) has adopted amendments to the Insurance Holding 
Company  System  Regulatory  Act  and  Regulation,  which, 
among other changes, introduce the concept of “enterprise risk” 
within  an  insurance  holding  company  system.  When  the 
amendments  are  adopted  by  a  particular  state,  the  amended 
Insurance  Holding  Company  System  Regulatory  Act  and 
Regulation impose more 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 controlling interest to make a confidential advance 
notice filing.

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 generally limit the 
payment of dividends or other distributions above a specified 
level.  Dividends  or  other  distributions  in  excess  of  such 
thresholds are “extraordinary” and are subject to prior notice 
and approval, or non-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 ceding 
company to obtain credit for reinsurance ceded, the terms and 
conditions of reinsurance agreements generally are not subject 
to regulation by any governmental authority.

A  primary  insurer  ordinarily  will  enter  into  a  reinsurance 
agreement only if it can obtain credit for the reinsurance ceded 
on its U.S. statutory-basis financial statements. As a result of 
the  requirements  relating  to  the  provision  of  credit  for 
reinsurance,  and  Arch  Re  U.S.  and  Arch  Re  Bermuda  are 

indirectly subject to certain regulatory requirements imposed 
by jurisdictions in which ceding companies are domiciled.

In general, credit for reinsurance is allowed if the reinsurer is 
licensed or “accredited” in the state in which the primary insurer 
is domiciled; or if none of the above applies, to the extent that 
the reinsurance obligations of the reinsurer are collateralized 
appropriately, typically through the posting of a letter of credit 
for the benefit of the primary insurer or the deposit of assets 
into  a  trust  fund  established  for  the  benefit  of  the  primary 
insurer. Most states have adopted provisions of the NAIC Credit 
for  Reinsurance  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. Arch Re Bermuda is approved 
as a “certified reinsurer” in 33 states.

On April  4,  2018  the  U.S.  and  the  European  Union  (“EU”) 
entered into the Bilateral Agreement between the United States 
of America  and  the  European  Union  on  Prudential  Matters 
Regarding Insurance and Reinsurance (the “EU-US Covered 
Agreement”)  that,  among  other  things,  would  eliminate 
reinsurance collateral requirements for qualified U.S. reinsurers 
operating in the EU insurance market, and eliminate reinsurance 
collateral requirements for qualified EU reinsurers operating in 
the  U.S.  insurance  market.  In  December  2018,  the  U.S. 
Secretary of the Treasury and the U.S. Trade Representative 
announced that they had reached agreement with the U.K. on 
a covered agreement (“UK Covered Agreement”) that would 
extend terms nearly identical to the EU Covered Agreement to 
insurers and reinsurers operating in the U.K. should the United 
Kingdom  ultimately  leave  the  EU.  The  NAIC  is  finalizing 
amendments  to  the  Credit  for  Reinsurance  Model  Law  and 
Regulation  that  would  implement  the  EU-US  Covered 
Agreement  and  the  UK  Covered  Agreement  and  eliminate 
reinsurance  collateral  requirements  for  qualified  reinsurers 
domiciled 
jurisdictions  deemed  “Reciprocal 
Jurisdictions”.

Risk Management and ORSA. In 2012, the NAIC adopted the 
Risk  Management  and  Own  Risk  and  Solvency Assessment 
Model Act, which requires domestic insurers to maintain a risk 
management framework and establishes a legal requirement for 
domestic insurers to conduct an ORSA in accordance with the 
NAIC’s  ORSA  Guidance  Manual.  The  ORSA  Model  Act 
provides that domestic insurers, or their insurance group, must 
regularly  conduct  an  ORSA  consistent  with  a  process 
comparable to the ORSA Guidance Manual process. The ORSA 
Model Act  also  provides  that,  no  more  than  once  a  year,  an 
insurer’s  domiciliary  regulator  may  request  that  an  insurer 
submit an ORSA summary report, or any combination of reports 
that together contain the information described in the ORSA 
Guidance  Manual,  with  respect  to  the  insurer  and/or  the 
insurance group of which it is a member. If and when the ORSA 
Model Act  is  adopted  by  an  individual  state,  the  state  may

2018 FORM 10-K

impose  additional  internal  review  and  regulatory  filing 
requirements on licensed insurers and their parent companies.

Cybersecurity.  The  NAIC  has  adopted  an  Insurance  Data 
Security Model Law, which, when adopted by the states, will 
require insurers, insurance producers and other entities required 
to be licensed under state insurance laws to comply with certain 
requirements under state insurance laws, such as developing 
and  maintaining  a  written  information  security  program, 
conducting risk assessments and overseeing the data security 
practices  of  third-party  vendors.  In  addition,  certain  state 
insurance  regulators  are  developing  or  have  developed 
regulations that may impose regulatory requirements relating 
to  cybersecurity  on  insurance  and  reinsurance  companies 
(potentially  including  insurance  and  reinsurance  companies 
that are not domiciled, but are licensed, in the relevant state). 
For  example,  the  New  York  State  Department  of  Financial 
Services has adopted a regulation pertaining to cybersecurity 
for  all  banking  and  insurance  entities  under  its  jurisdiction, 
effective  as  of  March 1,  2017,  and  the  California  legislature 
passed the California Consumer Privacy Act of 2018, which 
takes  effect  January  1,  2020,  both  of  which  apply  to  us.We 
cannot predict the impact these evolving laws and regulations 
may  have  on  our  business,  financial  condition  or  results  of 
operations, but we could incur additional costs resulting from 
compliance with such laws and regulations.

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 risk-based 
capital  requirement  decreases. The  mildest  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 a risk based capital model 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  guaranty 
insurance, among other lines of business, is typically exempt 
from participation in guaranty funds.

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, 
which is not a federal regulator or supervisor of insurance, but 
monitors the insurance industry for systemic risk, administers 
the Terrorism Risk Insurance Program Reauthorization Act of 
2015 (“TRIPRA”), consults with the states regarding insurance 
matters and develops federal policy on aspects of international 
insurance  matters.  See  “Risk  Factors-Risks  Related  to  Our 
Industry-We  could  face  unanticipated  losses  from  war, 
terrorism  and  political  instability,  and  these  or  other 
unanticipated losses could have a material adverse effect on 
our  financial  condition  and  results  of  operations”  for  more 
information on TRIPRA. In addition, FIO is authorized to assist 
the  U.S.  Secretary  of  the  Treasury  in  negotiating  “covered 
agreements”  between  the  U.S.  and  one  or  more  foreign 
governments or regulatory authorities that address insurance 
prudential measures. 

Certain  other  federal  laws  also  directly  or  indirectly  impact 
mortgage  insurers,  including  the  Real  Estate  Settlement 
Procedures  Act  of  1974  (“RESPA”),  the  Homeowners 
Protection Act of 1998 (“HOPA”), the Equal Credit Opportunity 
Act, the Fair Housing Act, the Truth In Lending Act (“TILA”), 
the Fair Credit Reporting Act of 1970 (“FCRA”), and the Fair 
Debt Collection Practices Act. Among other things, these laws 
and  their  implementing  regulations  prohibit  payments  for 
referrals  of  settlement  service  business,  require  fairness  and 
non-discrimination  in  granting  or  facilitating  the  granting  of 
credit, govern the circumstances under which companies may 
obtain and use consumer credit information, define the manner 
in  which  companies  may  pursue  collection  activities,  and 
require disclosures of the cost of credit and provide for other 
consumer protections.

GSE Eligible Mortgage Insurer Requirements. GSEs impose 
requirements on private mortgage insurers so that they may be 
eligible to insure loans sold to the GSEs, known as the Private 
Mortgage Insurer Eligibility Requirements or “PMIERs.” The 

ARCH CAPITAL

21

2018 FORM 10-K

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 and original credit score of performing 
loans, and the delinquency status of non-performing loans). Our 
eligible  mortgage  insurers  satisfied  the  PMIERs’  financial 
requirements as of December 31, 2018. 

On  September  27,  2018,  the  GSEs  released  revised  Private 
Mortgage  Insurer  Eligibility  Requirements  or  “revised 
PMIERs”. The revised PMIERs become effective on March 31, 
2019 and are not expected to have a significant impact on our 
eligible mortgage insurers operations or have a material impact 
on their capital position. While not yet effective, our eligible 
mortgage  insurers  satisfied  the  revised  PMIERs’  financial 
requirements as of December 31, 2018.

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  mediation  activities  operating  in  the  U.K.  both 
under  the  Financial  Services  and  Markets  Act  2000  (the 
“FSMA”). In May 2004, Arch Insurance Company Europe was 
granted the relevant permissions for the classes of insurance 
business which it underwrites in the U.K. In 2009, AUAL was 
licensed and authorized by the relevant U.K. regulator and the 
Lloyd’s Franchise Board and holds the relevant permissions for 
the classes of insurance business which are underwritten in the 
U.K. by Arch Syndicate 2012. Arch Syndicate 2012 has one 
member, Arch Syndicate Investments Ltd. (“ASIL”). 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 Europe and AUAL are subject to periodic 
assessment  by  the  PRA  along  with  all  regulated  firms. Arch 
Insurance Company Europe and AUAL are subject to regulation 
by both the PRA and FCA.

Lloyd’s Supervision. The operations of AUAL and related Arch 
Syndicate 2012 and its corporate member, ASIL, 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, including 
specifying  conditions  in  relation  to  underwriting  and  claims 
operations of Lloyd’s participants. 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. 
ASIL, as a member of Lloyd’s, is required to contribute 0.5% 
of Arch Syndicate 2012’s premium income limit 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. As a member of 
Lloyd’s, ASIL may also be required to contribute to the central 
fund by way of a supplement to a callable layer of up to 3% of 
Arch Syndicate 2012’s premium income limit for the relevant 
year  of  account.  In  addition,  AUAL,  on  behalf  of  Arch 
Syndicate 2012, is approved to underwrite excess and surplus 
lines  insurance  in  most  states  in  the  U.S.  through  Lloyd’s 
licenses. Such activities must be in compliance with the Lloyd’s 
requirements.

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 
and  Reinsurance 
Reinsurance  Regulation—Insurance 
Regulatory Regime” below for additional details.

Arch  Insurance  Company  Europe  and AUAL  (on  behalf  of 
Syndicate  2012)  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 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.

Financial  Services  Compensation  Scheme.  The  Financial 
Services  Compensation  Scheme  (“FSCS”)  is  a  scheme 
established under FSMA to compensate eligible policyholders 
of insurance companies who may become insolvent. The FSCS 
is funded by the levies that it has the power to impose on all 
insurers. Arch Insurance Europe could be required to pay levies 
to the FSCS.

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

Restrictions on Payment of Dividends. Under English law, all 
companies  are  restricted  from  declaring  a  dividend  to  their 
for 
shareholders  unless 
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  and  insurance  intermediaries  maintain  certain 
solvency margins and may restrict the payment of a dividend 
by Arch Insurance Company Europe, AUAL or ASIL. 

European  Union  Considerations.  Through  their  respective 
authorizations in the U.K., a Member State of the EU, Arch 
Insurance Company Europe’s and AUAL’s authorizations are 
recognized throughout the European Economic Area (“EEA”), 
subject  only 
to  certain  notification  and  application 
requirements.  This  authorization  enables  Arch  Insurance 
Company Europe and AUAL to exercise “passporting” rights 
which allows Arch Insurance Company Europe and AUAL to 
establish a branch in any other Member State of the EU, where 
such entity will be subject to the insurance regulations of each 
such Member State with respect to the conduct of its business 
in such Member State, but remain subject only to the financial 
and operational supervision by the PRA or FCA (as applicable). 
The conditions for the establishment of branches in Member 
States  of  the  EU  are  set  out  in  Solvency  II. Arch  Insurance 
Company  Europe  currently  has  branches  in  Germany,  Italy, 
Spain  and  Denmark  and  may  establish  branches  in  other 
Member  States  of  the  EU  in  the  future.  Further,  through  its 
passporting  rights,  Arch  Insurance  Company  Europe  and 
AUAL  have  the  freedom  to  provide  insurance  services 

anywhere in the EEA subject to compliance with certain rules 
governing such provision, including notification to the PRA or 
FCA, as applicable.

Following the referendum in June 2016 in which a majority of 
voting U.K. citizens voted in favor of the U.K. leaving the EU 
(“Brexit”), the U.K. withdrawal from the EU will lead to a loss 
of  passporting  rights  for  financial  institutions  in  the  U.K., 
except to the extent that any aspect of the regime is preserved 
in a separate agreement between the EU and the U.K. See “Risk 
Industry—The  United 
to  Our 
Factors—Risks  Related 
Kingdom’s referendum vote in favor of leaving the EU could 
adversely affect us.”

Canada

Arch  Insurance  Canada  and Arch  Re  Canada  are  subject  to 
federal,  as  well  as  provincial  and  territorial,  regulation  in 
Canada in the provinces and territories in which they underwrite 
insurance/reinsurance.  The  Office  of  the  Superintendent  of 
Financial Institutions (“OSFI”) is the federal regulatory body 
that, under the Insurance Companies Act (Canada), prudentially 
regulates  federal  Canadian  and  non-Canadian  insurance  and 
reinsurance  companies  operating  in  Canada. Arch  Insurance 
Canada is licensed to carry on insurance business by OSFI and 
in each province and territory. Arch Re Canada is licensed to 
carry on reinsurance business by OSFI and in the provinces of 
Ontario and Quebec.

Under the Insurance Companies Act (Canada), Arch Insurance 
Canada is required to maintain an adequate amount of capital 
in Canada, calculated in accordance with a test promulgated by 
OSFI called the Minimum Capital Test, and Arch Re Canada is 
required to maintain an adequate margin of assets over liabilities 
in Canada, calculated in accordance with a test promulgated by 
OSFI  called  the  Branch Adequacy  of Assets Test.  OSFI  has 
implemented  a 
for  assessing 
risk-based  methodology 
insurance/reinsurance companies operating in Canada known 
as its “Supervisory Framework.” In applying the Supervisory 
Framework, OSFI considers the inherent risks of the business 
and the quality of risk management for each significant activity 
of each operating entity. Under the Insurance Companies Act 
(Canada),  approval  of  the  Minister  of  Finance  (Canada)  is 
required in connection with certain acquisitions of shares of, or 
control  of,  Canadian  insurance  companies  such  as  Arch 
Insurance  Canada,  and  notice  to  and/or  approval  of  OSFI  is 
required  in  connection  with  the  payment  of  dividends  by  or 
redemption of shares by Canadian insurance companies such 
as Arch Insurance Canada.

Ireland 

General.  The  CBOI  regulates  insurance  and  reinsurance 
companies and intermediaries authorized in Ireland. Our three 
Irish  operating  subsidiaries  are  Arch  Re  Europe,  Arch  MI 
Europe and Arch Underwriters Europe. Arch Re Europe was

licensed and authorized by the CBOI as a non-life reinsurer in 
October 2008 and as a life reinsurer in November 2009. Arch 
MI Europe was licensed and authorized by the CBOI as a non-
life insurer in December 2011. Arch Underwriters Europe was 
registered  by  the  CBOI  as  an  insurance  and  reinsurance 
intermediary in July 2014. Arch Re Europe, Arch MI Europe 
and Arch Underwriters Europe are subject to the supervision of 
the  CBOI  and  must  comply  with  Irish  insurance  acts  and 
regulations as well as with directions and guidance issued by 
the CBOI.

Arch Re Europe and Arch MI Europe are required to comply 
with Solvency II requirements. See “European Union Insurance 
and  Reinsurance  Regulation—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 MI Europe 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  CBOI  is  required  before  any  person  can  acquire  or 
increase a qualifying holding in an Irish insurer or reinsurer, 
including Arch MI Europe 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 
the 
management of the undertaking.

influence  over 

Restrictions on Payment of Dividends. Under Irish company 
law, Arch Re Europe, Arch MI Europe 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 CBOI has powers to intervene if a dividend payment 
were to lead to a breach of regulatory capital requirements. 

European Union Considerations. As Arch Re Europe, Arch MI 
Europe and Arch Underwriters Europe are authorized by the 
CBOI 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 MI Europe 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, they will remain subject to financial and operational 
supervision by the CBOI only. Arch Re Accident & Health ApS 
(“Arch Re Denmark”) is an underwriting agency underwriting 
accident and health business for Arch Re Europe in Denmark. 
Arch  Re  Europe  also  has  a  branch  in  the  U.K.,  which 
underwrites non-life reinsurance risk for Arch Re Europe. Arch 
Re Europe also has a branch outside the EEA, Arch Reinsurance 
Europe Designated Activity Company, Dublin (Ireland), Zurich 
Branch (“Arch Re Europe Swiss Branch”).

As part of its application for registration, Arch Underwriters 
Europe requested the CBOI to make the necessary notifications 
to permit it to provide insurance and reinsurance intermediary 
services in all EEA Member States. Arch Underwriters Europe 
currently has branches in the following EU countries: the U.K., 
Italy and Finland.

Following Brexit, the U.K.'s withdrawal from the EU will lead 
to  a  loss  of  passporting  rights  for  EEA  financial  institutions 
(including our Irish operating subsidiaries) into the U.K., except 
to  the  extent  that  any  aspect  of  the  regime  is  preserved  in  a 
separate agreement between the EU and the U.K. Absent such 
agreement, 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 “Risks Relating to Our Industry 
—The United Kingdom’s referendum vote in favor of leaving 
the EU could adversely affect us.”

Switzerland 

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

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 II is 
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.

Insurers and reinsurers established in a Member State of the EU 
have the freedom to establish branches in and provide services 
to all EEA states. Arch Insurance Company Europe and AUAL, 
being established in the U.K. and regulated by the PRA and 
FCA,  are  able,  subject  to  regulatory  notifications  and  there 
being  no  objection  from  the  relevant  U.K.  regulator  and  the 
Member States concerned, to establish branches and provide 
insurance and reinsurance services in all EEA Member States.

Following Brexit, the U.K.’s withdrawal from the EU will lead 
to a loss of passporting rights from U.K. financial institutions 
into the EU, except to the extent that any aspect of the regime 
is preserved in a separate agreement between the U.K. and the 
U.K.  See  “Risks  Relating  to  Our  Industry  –The  United 
Kingdom’s referendum vote in favor of leaving the EU could 
adversely affect us.”

Arch  Re  Europe  and Arch  MI  Europe,  being  established  in 
Ireland and authorized by the CBOI are able, subject to similar 
regulatory notifications and there being no objection from the 
CBOI and the Member States concerned, to establish branches 
and provide reinsurance services, and, in respect of Arch MI 
Europe, insurance services in all EEA states.

Solvency  II  does  not  prohibit  EEA  insurers  from  obtaining 
reinsurance from reinsurers licensed outside the EEA, such as 
Arch Re Bermuda. As such, and subject to the specific rules in 
each Member State, Arch Re Bermuda may do business from 
Bermuda with insurers in EEA Member States, but it may not 
directly operate its reinsurance business within the EEA. Article 
172  of  Solvency  II  provides  that  reinsurance  contracts 
concluded by insurance undertakings in the EEA with reinsurers 
having their head office in a country whose solvency regime 
has been determined to be equivalent to Solvency II shall be 

treated  in  the  same  manner  as  reinsurance  contracts  with 
undertakings in the EEA authorized under Solvency II. In this 
regard,  with  effect  from  January  1,  2016,  the  supervisory 
regime, including the solvency regime, in Bermuda has been 
determined to be equivalent to that laid down in Solvency II, 
except  in  relation  to  captives  and  special  purpose  insurers. 
Solvency II also includes specific measures providing for the 
supervision of insurance and reinsurance groups. However, as 
a  consequence  of  the  above  determination  of  equivalence, 
pursuant to Article 260 of Solvency II, regulators within the 
EEA are required to rely on the worldwide group supervision 
exercised by the BMA. EIOPA has also indicated that, on a case 
by case basis, groups subject to this worldwide supervision may 
be exempted from any EEA sub-group 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  all  distributors  of 
insurance  and  reinsurance  products  (including  insurers  and 
reinsurers  selling  directly  to  customers)  and  strengthens  the 
regulatory regime applicable to distribution activities through 
increased transparency, information and conduct requirements. 
The principal impact of the IDD is on the insurance market, 
however,  requirements  that  apply  across  insurance  and 
include  more  specific  conditions  regarding 
reinsurance 
knowledge 
continuing  professional  development 
and 
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  CBOI,  is  able,  subject  to  regulatory 
notifications and there being no objection from the CBOI, to 
establish branches and provide services in all EEA states.

Privacy. The European General Data Protection Regulation (the 
“GDPR”) came into effect on May 25, 2018. The GDPR aims 
to introduce consistent data protection rules across the EU and 
EEA, 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 
GDPR contains a number of new 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 mandatory Data Protection Impact 
Assessments  in  connection  with  higher  risk  data  processing 
activities.

TAX MATTERS

The following summary of the taxation of Arch Capital and the 
taxation of our shareholders is based upon current law and is 
for  general 
judicial  or 
information  only.  Legislative, 
administrative changes may be forthcoming that could affect 
this summary.

The  following  legal  discussion  (including  and  subject  to  the 
matters and qualifications set forth in such summary) of certain 
tax  considerations  (a) under  “—Taxation  of Arch  Capital—
Bermuda”  and  “—Taxation  of  Shareholders—Bermuda”  is 
based  upon  the  advice  of  Conyers  Dill &  Pearman  Limited, 
Hamilton, Bermuda and (b) under “—Taxation of Arch Capital-
United  States,”  “—Taxation  of  Shareholders-United  States 
Taxation,”  “—Taxation  of  Our  U.S.  Shareholders”  and  “—
United  States  Taxation  of  Non-U.S.  Shareholders”  is  based 
upon the advice of Cahill Gordon & Reindel LLP, New York, 
New York (the advice of such firms does not include accounting 
matters, determinations or conclusions relating to the business 
or  activities  of Arch  Capital).  The  summary  is  based  upon 
current  law  and  is  for  general  information  only.  The  tax 
treatment of a holder of our common or preferred shares, or of 
a person treated as a holder of our shares for U.S. federal income, 
state, local or non-U.S. tax purposes, may vary depending on 
the  holder’s  particular  tax  situation.  Legislative,  judicial  or 

administrative changes or interpretations may be forthcoming 
that could be retroactive and could affect the tax consequences 
to us or to holders of our shares.

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. 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 indirectly, to the Bermuda government.

United States. Arch Capital and its non-U.S. subsidiaries intend 
to conduct their operations in a manner that will not cause them 
to be treated as engaged in a trade or business in the U.S. 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 definitive 
identification of activities which constitute being engaged in a 
trade  or  business  in  the  U.S.  is  not  provided  by  the  Internal 
Revenue Code of 1986, as amended (the “Code”), or regulations 
or  court  decisions,  there  can  be  no  assurance  that  the  U.S. 
Internal Revenue Service (“IRS”) will not contend successfully 
that Arch Capital or its non-U.S. subsidiaries are or have been 
engaged in a trade or business in the U.S. A foreign corporation 
deemed to be so engaged would be subject to U.S. 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 regulations. Penalties 
may be assessed for failure to file tax returns. The 30% branch

profits tax is imposed on net income after subtracting the regular 
corporate tax and making certain other adjustments.

Under the income tax treaty between Bermuda and the U.S. (the 
“Treaty”), Arch Capital's Bermuda insurance subsidiaries will 
be subject to U.S. income tax on any insurance premium income 
found to be 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 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 there can be no 
assurances, Arch Capital believes that its Bermuda insurance 
subsidiaries are 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  company's  investment  income 
could be subject to U.S. 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 applicable treaties.

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  tax  (reduced  to  5%  for  the  2018 
taxable year and increased to 12.5% for the 2026 taxable year 
and  the  subsequent  taxable  years)  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

United  Kingdom.  Our  U.K.  subsidiaries  are  companies 
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  Underwriters  Europe  will  be 
subject  to  U.K.  corporation  tax  on  the  profits  (both  income 
profits and chargeable gains) attributable to each branch. The 
main rate of U.K. corporation tax for the financial year starting 
April 1, 2018 is 19% on profits. It has been announced that the 
U.K. corporation tax rate will remain at 19% on profits for the 
financial year starting April 1, 2019, and will reduce to 17% on 
profits for the financial year starting April 1, 2020.

Canada. Arch Insurance Canada, a Canadian federal insurance 
company,  commenced  underwriting  in  2013. Arch  Re  U.S., 
through  a  branch,  commenced  underwriting  reinsurance  in 
Canada in January 2015. 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 11% and 
16%.

Ireland. Each of Arch Re Europe, Arch MI Europe and Arch 
Underwriters Europe is incorporated and resident in Ireland for 
corporation tax purposes and will be subject to Irish corporate 
tax  on  its  worldwide  profits,  including  the  profits  of  the 
branches of Arch Re Europe and Arch Underwriters Europe. 
Any creditable foreign 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 Underwriters Europe’s branches. The current rate of Irish 
corporation tax applicable to such trading profits is 12.5%.

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) who hold their common shares and preferred shares as 
capital  assets  and  as  beneficial  owners.  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 
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 

trusts, 

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  considering 
making 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 partner of a partnership holding 
our common shares or preferred shares, you should consult your 
tax advisor.

For purposes of this discussion, the term “U.S. Person” means:

• 
• 

• 

• 

an individual who is a citizen or resident of the U.S.; 
a corporation or entity treated as 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; 

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; or 

• 

any other person or entity that is treated for U.S. federal 
income tax purposes as if it were one of the foregoing.

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

income” (“RPII”) and passive foreign investment companies 
(“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. Person 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  will  generally  include  its  dividend 
income and its net gains from the disposition of our common 
shares and preferred shares, unless such dividend income or net 
gains are derived in the ordinary course of the conduct of a trade 
or business (other than a trade or business that consists of certain 
passive or trading activities).

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

United States—Sale, Exchange or Other Disposition. Subject 
to the discussions below relating to the potential application of 
the CFC, RPII and PFIC rules, holders of common shares and 
preferred shares generally will recognize capital gain or loss 
for U.S. federal income tax purposes on the sale, exchange or 
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 if we have sufficient earnings and profits, 
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. Person 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  preference  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 will be treated as a CFC with respect to any 
taxable year if at any time during such taxable year, one or more 
“10% 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 regulations thereunder). For taxable years 
beginning on or before December 31, 2017, a 10% Shareholder 
means any shareholder 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% Shareholder also includes any 
shareholder  who 
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% Shareholder. 

is  considered 

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% Shareholder 
with  respect  to  us  or  any  of  such  non-U.S.  subsidiaries  (as 
applicable). If we 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) 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. Generally, we do not 
expect the gross RPII of any of our non-U.S. subsidiaries to 
equal  or  exceed  20%  of  its  gross  insurance  income  in  any 
taxable year for the foreseeable future (the “RPII 20% gross 
income exception”). Consequently, we do not expect any U.S. 
person  owning  common  shares  or  preferred  shares  to  be 
required to include in gross income for U.S. federal income tax 
purposes RPII income, but there can be no assurance that this 
will be the case.

the  Code  generally  provides 

Section 953(c)(7)  of 
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  domestic  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  U.S.  Treasury  Department  (“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  foreign  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 that Section 1248 and the requirement 
to  file  Form 5471  will  not  apply  to  a  less  than  10%  U.S. 
Shareholder because Arch Capital is not directly engaged in the 
insurance business. There can be no assurance, however, that 
the IRS will interpret the proposed 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  Treasury  were  to  make  Section 1248  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 
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.  Prospective  investors  that  are  tax 
exempt entities are urged to 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. 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

FATCA Withholding. Sections 1471 through 1474 to the Code, 
the  Foreign  Account  Tax  Compliance  Act 
known  as 
(“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 
respective 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  into  intergovernmental  agreements  to  implement 
FATCA (“IGAs”) with a number of jurisdictions. Bermuda has 
signed an IGA with the U.S. Different rules than those described 
above may apply under such an IGA.

Although  dividends  with  respect  to  our  common  shares  or 
preferred shares will generally 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.

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

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

insurance business and the failure of the company to satisfy the 
preceding  25%  test  is  due  solely  to  run-off  related  or  other 
specified circumstances involving the insurance business. The 
PFIC statutory provisions contain a look-through rule that states 
that, for purposes of determining whether a foreign corporation 
is  a  PFIC,  such  foreign  corporation  shall  be  treated  as  if  it 
“received directly its proportionate share of the income” and as 
if it “held its proportionate share of the assets” of any other 
corporation  in  which  it  owns  at  least  25%  of  the  stock.  We 
believe that we were not a PFIC for any taxable year beginning 
on or before December 31, 2017 and we are not expecting to 
become a PFIC for any taxable year beginning after December 
31, 2017 and we will use reasonable best efforts to cause us and 
each of our majority owned non-U.S. insurance subsidiaries not 
to constitute a PFIC. 

In April 2015, the IRS issued proposed regulations in an attempt 
to define the foreign insurance company exception to the PFIC 
rules  (the  “proposed  PFIC  insurance  regulations”).  The 
proposed PFIC insurance regulations are likely to be revised in 
light  of  the  modified  active  insurance  company  exception 
contained in the Tax Cuts Act (as described above).

No  regulations  interpreting  the  substantive  PFIC  provisions 
have  yet  been  finalized.  It  is  possible  that  the  regulations 
interpreting the PFIC provisions will be issued in the future and 
contain  rules  different  from  those  in  the  proposed  PFIC 
insurance regulations. 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 
shareholders who are not U.S. Persons (“Non-U.S. holders”) 
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 realized 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 in the U.S. or such person is present in 
the U.S. for 183 days or more in the taxable year the gain is 
realized 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.

ITEM 1A.  RISK FACTORS

Set forth below are risk factors relating to our business. These 
risks and uncertainties are not the only ones we face. There may 
be additional risks that we currently consider not to be material 
or of which we are not currently aware, and any of these risks 
could cause our actual results to differ materially from historical 
or anticipated results. You should carefully consider these risks 
along  with  the  other  information  provided  in  this  report, 
including  our  “Management’s  Discussion  and  Analysis  of 
Financial  Condition  and  Results  of  Operations”  and  our 
accompanying consolidated financial statements, as well as the 
information  under  the  heading  “Cautionary  Note  Regarding 
Forward-Looking Statements” before investing in any of our 
securities. We may amend, supplement or add to the risk factors 
described below from time to time in future reports filed with 
the SEC.

Risks Relating to Our Industry

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. We also compete with new companies that continue to 
be formed to enter the insurance and reinsurance markets, as 
well  as  with  other  capital  market  participants  that  create 
alternative  products  intended  to  compete  with  reinsurance 
products. Certain new companies entering the insurance and 
reinsurance markets are pursuing more aggressive investment 
strategies  than  do  we  and  other  traditional  reinsurers,  which 
may result in downward pressure on premium rates. In our U.S. 
mortgage business, we compete with other private mortgage 
insurers,  with  the  Federal  Housing  Administration,  and, 
increasingly,  with  well  capitalized  multiline  reinsurers  and 
capital  markets  alternatives  to  private  mortgage  insurance. 
Competition  within  the  private  mortgage  insurance  industry 
could result in the loss of customers, lower premiums, riskier 
credit  guidelines  and  other  changes  that  could  lower  our 
revenues or increase our expenses.

increased  competition  as  a  result  of 

In  addition,  there  has  been  significant  consolidation  in  the 
insurance and reinsurance sector in recent years and we may 
experience 
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. 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 expect to continue to experience periods characterized by 
excess underwriting capacity and unfavorable premium rates.

Historically, 
insurers  and  reinsurers  have  experienced 
significant fluctuations in operating results due to competition, 
frequency  of  occurrence  or  severity  of  catastrophic  events, 
levels  of  capacity,  general  economic  conditions,  changes  in 
equity,  debt  and  other  investment  markets,  changes  in 
legislation, case law and prevailing concepts of liability and 
other factors. In particular, 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. The supply of insurance and reinsurance 
has  increased  over  the  past  several  years  and  may  increase 
further, 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.

Claims  for  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.  Catastrophes  can  be  caused  by  various 
events,  including  hurricanes,  floods,  tsunamis,  windstorms, 
earthquakes, hailstorms, tornadoes, explosions, severe winter 
fires,  droughts  and  other  natural  disasters. 
weather, 
Catastrophes  can  also  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

the  inherent  uncertainties  in  making  such  determinations 
resulting  from  several  factors,

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

including 

In  addition,  over  the  past  several  years,  changing  weather 
patterns and climatic conditions, such as global warming, have 
added to the unpredictability and frequency of natural disasters 
in certain parts of the world and created additional uncertainty 
as to future trends and exposures. Although the loss experience 
of  catastrophe  insurers  and  reinsurers  has  historically  been 
characterized as low frequency, there is a growing consensus 
today that climate change increases the frequency and severity 
of extreme weather events and, in recent years, the frequency 
of  major  catastrophes  appears  to  have  increased.  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.

Additionally, we cannot predict how legal, regulatory and/or 
social responses to concerns around global climate change may 
impact  our  business.  Although  we  attempt  to  manage  our 
exposure  to  such  events  through  the  use  of  underwriting 
controls,  risk  models,  and  the  purchase  of  third-party 
reinsurance,  catastrophic  events  are  inherently  unpredictable 
and the actual nature of such events when they occur could be 
more frequent or severe than contemplated in our pricing and 
risk management expectations. As a result, the occurrence of 
one or more catastrophic events could have an adverse effect 
on our results of operations and financial condition.

attacks  and  political

instability,  and 

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. 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  under  the  Terrorism  Risk  Insurance 
Extension  Act  of  2005  and  the  Terrorism  Risk  Insurance 
Program  Reauthorization  Act  of  2007,  and  amended  and 
extended again by TRIPRA, 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 TRIPRA for up to 
81%  for  2019  and  80%  for  2020,  in  each  case  subject  to  a 
mandatory deductible of 20% of our prior year’s direct earned 
premium  for  covered  property  and  liability  coverages.  The 
program  trigger  for  calendar  year  2019  is  $180 million  and 
$200 million in 2020. 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.

Political, regulatory, legislative and industry initiatives could 
adversely affect our business.

Governmental  authorities  in  the  U.S.  and  worldwide  have 
become increasingly interested in potential risks posed by the 
insurance industry as a whole, and to commercial and financial 
systems  in  general  and  there  may  be  increased  regulatory 
intervention in our industry in the future. For example, in the 
U.S.,  the  federal  government  (including  federal  consumer 
protection  authorities)  has  increased  its  scrutiny  of  the 
insurance  regulatory  framework  in  recent  years,  and  various 
state legislators are considering or have enacted laws that will 
alter  and  likely  increase  state  regulation  of  insurance  and 
reinsurance  companies  and  holding  companies.  The  U.S. 
mortgage insurance industry has also been subject to increased 
federal  and  state  regulatory  scrutiny  (including  by  state 
insurance  regulatory  authorities),  which  could  generate  new 
regulations, regulatory actions or investigations.

In the EU, Solvency II imposed economic risk-based solvency 
requirements  across  all  EU  Member  States  covering 
quantitative  capital  requirements,  qualitative  regulatory 
reviews and market discipline. In addition, Solvency II imposes 
significant requirements for our EU-based regulated companies 

ARCH CAPITAL

which require substantial documentation and implementation 
effort.

The  BMA  has  also  implemented  and  imposed  additional 
requirements  on  the  commercial  insurance  companies  it 
regulates, driven, in large part, by Solvency II. The European 
Commission has adopted a decision concluding that Bermuda 
meets the full equivalence criteria under Solvency II. 

While we cannot predict the exact nature, timing or scope of 
any  possible  governmental  initiatives,  such  proposals  could 
adversely affect our business by, among other things: providing 
reinsurance capacity in markets and to consumers that we target; 
requiring  our  further  participation  in  industry  pools  and 
guaranty associations; expanding the scope of coverage under 
existing  policies  (e.g.,  following  large  disasters);  further 
regulating the terms of insurance or reinsurance contracts; or 
disproportionately  benefiting  the  companies  of  one  country 
over those of another.

In  addition,  increased  scrutiny  by  insurance  regulators  of 
investments in or acquisitions of insurers or insurance holding 
companies by private equity firms or hedge funds may result 
in  imposition  of  additional  regulatory  requirements  and 
restrictions. We have in the past partnered with private equity 
firms in making investments and may do so in the future. This 
increased  scrutiny  may  make 
to  complete 
investments with private equity or hedge funds should we seek 
to do so.

it  difficult 

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  involving  actuarial  and 
statistical  projections,  at  a  given  point  in  time,  of  our 
expectations of the ultimate settlement and administration costs 
of  losses  incurred.  We  utilize  actuarial  models  as  well  as 
available historical insurance industry loss ratio experience and 
loss development patterns to assist in the establishment of loss 
reserves.  Most  or  all  of  these  factors  are  not  directly 
quantifiable, particularly on a prospective basis, and the effects 
of  these  and  unforeseen  factors  could  negatively  impact  our 
ability to accurately assess the risks of the policies that we write. 
Changes  in  the  assumptions  used  by  these  models  or  by 
management  could  lead  to  an  increase  in  our  estimate  of 
ultimate  losses  in  the  future.  In  addition,  there  may  be 
significant reporting lags between the occurrence of the insured 
event  and  the  time  it  is  actually  reported  to  the  insurer  and 
additional  lags  between  the  time  of  reporting  and  final 
settlement of claims. Unfavorable development in any of these 
factors could cause the level of reserves to be inadequate. In 
addition, the estimation of loss reserves is also 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 will deviate, perhaps 
substantially,  from  the  reserve  estimates  reflected  in  our 
financial statements.

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

In accordance with mortgage insurance industry practice, we 
establish loss reserves only for loans in our existing delinquency 
inventory. Because our mortgage insurance reserving process 
does not take account of the impact of future losses from loans 
that are not delinquent, mortgage insurance loss reserves are 
not  intended  to  be  an  estimate  of  total  future  losses.  Our 
expectation of total future losses under our mortgage insurance 
policies in force at any period end is not reflected in our financial 
statements.  In  addition  to  establishing  loss  reserves  for 
delinquent loans, under GAAP, we are required to establish a 
premium  deficiency  reserve  for  our  mortgage  insurance 
products if the amount of expected future losses for a particular 
product  and  maintenance  costs  for  such  product  exceeds 
expected future premiums, existing reserves and the anticipated 
investment income. We evaluate whether a premium deficiency 
exists  quarterly.  There  can  be  no  assurance  that  premium 
deficiency reserves will not be required in future periods. If this 
were to occur, our results of operations and financial condition 
could be adversely affected.

As of December 31, 2018, our consolidated reserves for unpaid 
losses and loss adjustment expenses, net of unpaid losses and 
loss  adjustment  expenses  recoverable,  were  approximately 
$9.04  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 relatively limited historical information 
has been reported to us through December 31, 2018.

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

insurance  business, 

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. 
to  utilizing 
mortgage 
reinsurance, we have developed a proprietary risk model that 
simulates the maximum loss resulting from a severe economic 
event impacting the housing market. We cannot be certain that 
any of these loss limitation methods will be effective. We also 
seek to limit our loss exposure by geographic diversification. 
Geographic zone limitations involve significant underwriting 
judgments, 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 
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. No assurances can be made that 
these loss limitation methods will be effective and mitigate our 
loss  exposure.  One  or  more  catastrophic  events  or  severe 
economic events could result in claims 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.  See  “Management’s  Discussion  and 
Analysis of Financial Condition and Results of Operations—
Catastrophic Events and Severe Economic Events.” 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.

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,  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. 
Depending  on  market  conditions,  we  could  incur  additional 
realized and unrealized losses on our investment portfolio in 
future periods, which could have a material adverse effect on 
our  results  of  operations,  financial  condition  and  business. 
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 United Kingdom’s referendum vote in favor of leaving the 
EU could adversely affect us.

In a referendum in June 2016, a majority of voting U.K. citizens 
voted in favor of Brexit, whereby the U.K. will leave the EU. 
The  U.K.  government  invoked Article  50  of  the  Treaty  on 
European  Union  (“Article  50”)  in  2017  and  will  have  to 
withdraw from the EU on March 29, 2019, unless an extension 
to this deadline is agreed between the U.K government and the 
EU. There remains considerable uncertainty as to exactly when 
Brexit  will  take  effect;  the  extent  of  any  transitional  period 
allowing  a  continuation  of  passporting;  and  the  ultimate 
structure of the U.K’s future relationship with the EU. During 
this period and beyond, the impact of the U.K.’s withdrawal on 
the  U.K.  and  European  economies  and  the  broader  global 
economy  could  be  significant, 
in  negative 
consequences, such as increased volatility and illiquidity, and 
potentially lower economic growth in various markets in the 
U.K., Europe and globally and could continue to contribute to 
instability in global financial and foreign exchange markets. 
Brexit  could  also  have  the  effect  of  disrupting  the  free 
movement of goods, services and people between the U.K. and 
the  EU.  We  anticipate  that  Brexit  may  disrupt  our  U.K. 
domiciled entities, including our Lloyd’s syndicate, and their 
ability  to  “passport”  within  the  EU.  Similarly,  Brexit  may 
disrupt the ability of our EU domiciled entities to access the 
U.K. markets although the U.K is attempting to mitigate this 
by introducing a temporary permissions regime which, in the 
event of there being no transitional period, will allow firms that

the longer term to operate in the U.K for a limited period after 
withdrawal,  while  they  seek  authorization  from  the  U.K. 
regulators.  The  full  effects  of  Brexit  are  uncertain  and  will 
depend on any agreements the U.K. may make to retain access 
to EU markets.

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.

The negative impact of these events on economic conditions 
and global markets could have an adverse effect on our business, 
financial condition and liquidity. For example, this crisis may 
cause the value of the European currencies, including the Euro 
and the British Pound Sterling, to further depreciate against the 
U.S. Dollar, which in turn could materially adversely impact 
assets denominated in such currencies held in our investment 
portfolio  or  results  of  our  European  book  of  business.  In 
addition, the applicable legal framework and the terms of our 
Euro-denominated 
reinsurance 
agreements generally do not address withdrawal by a member 
state from the Eurozone or a break-up of the EU, which could 
create uncertainty in our payment obligations and rights under 
those  policies  and  agreements  in  the  event  that  such  a 
withdrawal or break-up does occur.

Additionally, a contagion effect of a possible default of one or 
more  EU  Member  States  and/or  their  withdrawal  from  the 
Eurozone, or the failure of financial institutions, on the global 
economy,  including  other  EU  Member  States  and  our 
counterparties located in those countries, or a break-up of the 
EU  could  have  a  material  adverse  effect  on  our  business, 
financial  condition,  results  of  operations  and  liquidity. As  a 
result of Brexit, other European countries may seek to conduct 
referenda with respect to their continuing membership with the 
EU. Given these possibilities and others we may not anticipate, 
as well as the lack of comparable precedent, the full extent to 
which our business, results of operations and financial condition 
could be adversely affected by Brexit is uncertain.

The  risk  associated  with  underwriting  treaty  reinsurance 
business could adversely affect us.

Like other reinsurers, our reinsurance group does not separately 
evaluate each of the individual risks assumed under reinsurance 
treaties. Therefore,  we  are  largely  dependent  on  the  original 
underwriting  decisions  made  by  ceding  companies.  We  are 
subject  to  the  risk  that  the  ceding  companies  may  not  have 
adequately  evaluated  the  risks  to  be  reinsured  and  that  the 
premiums ceded may not adequately compensate us for the risks 
we assume.

reinsurance 

agreements.  Our 

For  the  purposes  of  managing  risk,  we  use  reinsurance, 
retrocessional coverage and capital markets transactions. In the 
normal course of business, our insurance subsidiaries cede a 
portion of their premiums through pro rata, excess of loss and 
facultative 
reinsurance 
subsidiaries  purchase  a  limited  amount  of  retrocessional 
coverage as part of their aggregate risk management program. 
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 
subsidiaries,  and  the  ceding  company.  Economic  conditions 
could also have a material impact on our ability to manage our 
risk  aggregations  through  reinsurance  or  capital  markets 
transactions.  The  availability  and  cost  of  reinsurance  and 
retrocessional protection is subject to market conditions, which 
are beyond our control. As a result of such market conditions 
and other factors, we may not be able to successfully mitigate 
risk through reinsurance and retrocessional arrangements.

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.  Although  we  have  not  experienced  any 
material credit losses to date, 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. 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.

Our reliance on brokers subjects us to their credit risk.

In accordance with industry practice, we generally pay amounts 
owed on claims under our insurance and reinsurance contracts 
to brokers, and these brokers, in turn, pay these amounts to the 
clients that have purchased insurance or reinsurance from us. 
In some jurisdictions, if a broker fails to make such payment, 
we may remain liable to the insured or ceding insurer for the 

ARCH CAPITAL

36

2018 FORM 10-K

deficiency. Likewise, in certain jurisdictions, when the insured 
or ceding company pays the premiums for these contracts to 
brokers for payment to us, these premiums are considered to 
have  been  paid  and  the  insured  or  ceding  company  will  no 
longer be liable to us for those amounts, whether or not we have 
actually received the premiums from the broker. Consequently, 
we assume a degree of credit risk associated with our brokers. 
To date, we have not experienced any losses related to this credit 
risk.

Emerging claim and coverage issues may adversely affect our 
business.

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

Risks Relating to Our Company

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 
regulatory 
expanded  operations;  obtaining  necessary 
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.

Changes  in  current  accounting  principles  and  practices  and 
financial  reporting  requirements  may  materially  affect  our 
reported financial results and our reported financial condition.

Our  failure  to  manage  successfully  any  of  the  foregoing 
challenges  and  risks  may  adversely  impact  our  results  of 
operations.

Our  financial  statements  are  prepared  in  accordance  with 
GAAP,  which  is  periodically  revised  by  the  Financial 
Accounting Standards Board (“FASB”), and they are subject to 
the accounting-related rules and interpretations of the SEC. We 
are  required  to  adopt  new  and  revised  accounting  standards 
implemented  by  the  FASB.  Unanticipated  developments  in 
accounting  practices  may  require  us  to  incur  considerable 
additional  expenses  to  comply  with  such  developments, 
particularly if we are required to prepare information relating 
to prior periods for comparative purposes or to apply the new 
requirements  retroactively.  The 
in 
accounting  principles,  practices  and  standards,  particularly 
those that apply to insurance companies, cannot be predicted 
but  may  affect  the  calculation  of  net  earnings,  shareholders' 
equity  and  other  relevant  financial  statement  line  items.  In 
addition,  such  changes  may  cause  additional  volatility  in 
reported  earnings,  decrease  the  understandability  of  our 
financial results and affect the comparability of our reported 
results with the results of others.

impact  of  changes 

The  ultimate  performance  of  the  Arch  MI  U.S.  mortgage 
insurance portfolio remains uncertain.

Arch MI U.S. had risk in force of approximately $71.0 billion, 
before  external  reinsurance,  as  of  December 31,  2018, 
including $4.7 billion of risk in force originated in 2008 and 
prior. 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  business  in  our  insured  loan  portfolio  may 
affect losses and remain uncertain.

including, 

The frequency and severity of claims we incur will be uncertain 
and will depend largely on general economic factors outside of

our 
unemployment,  home  prices  and  interest  rates  in  the  U.S. 
Deteriorating economic conditions in the U.S. could adversely

portfolio and could adversely affect our results of operations 
and financial condition.

Generally, we cannot cancel mortgage insurance coverage or 
adjust renewal premiums during the life of a mortgage insurance 

policy. As  a  result,  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 on the acquired UGC insured 
loan portfolio, and the associated investment income, may not 
be adequate to compensate us for the risks and costs associated 
with the insurance coverage provided to customers.

A 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.

Third-party rating agencies, such as A.M. Best, assess and rate 
the  financial  strength  of  insurers  and  reinsurers  based  upon 
criteria established by the rating agencies, which criteria are 
subject  to  change.  Ratings  are  an  important  factor  in 
establishing  the  competitive  position  of  insurance  and 
reinsurance companies. Insureds, ceding insurers, brokers and 
reinsurance intermediaries use these ratings as one measure by 
which to assess the financial strength and quality of insurers 
and reinsurers. These ratings are often an important factor in 
the  decision  by  an  insured,  ceding  insurer,  broker  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 assigned to us by them. Such ratings may be 
revised  downward  or  revoked  at  the  sole  discretion  of  such 
ratings agencies in response to a variety of factors, including a 
minimum  capital  adequacy  ratio,  management,  earnings, 
capitalization and risk profile. For further information on our 
financial  strength  and/or  issuer  ratings,  see  “Management’s 
Discussion and Analysis of Financial Condition and Results of 
Operations—Liquidity and Capital Resources.” We can offer 
no assurances that our ratings will remain at their current levels 
or that any of our ratings which under review or watch by ratings 
agencies will remain unchanged. We believe it is possible that 
rating agencies may heighten the level of scrutiny they apply 
when analyzing companies in our industry, may increase the 
frequency and scope of their reviews, may request additional 
information  from  the  companies  that  they  rate  (including 
additional information regarding the valuation of investment 
securities held), and may adjust upward the capital and other 
requirements  employed  in  their  models  for  maintenance  of 
certain rating levels.

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  products  and 
services, as well as new sales of our products and services. 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. 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 
addition,  a  downgrade  in  ratings  of  certain  of  our  operating 
subsidiaries would in certain cases constitute an event of default 
under our credit facilities. See “Management’s Discussion and 
Analysis of Financial Condition and Results of Operations—
Contractual  Obligations  and  Commercial  Commitments—
Letter  of  Credit  and  Revolving  Credit  Facilities”  for  a 
discussion of our credit facilities.

We can offer no assurances that our ratings will remain at their 
current levels or that any of our ratings under review or watch 
by rating agencies will remain unchanged.

Our success will depend on our ability to maintain and enhance 
effective operating procedures and internal controls and our 
enterprise risk management (“ERM”) program.

Operational risk and losses can result from, among other things, 
fraud, errors, failure to document transactions properly or to 
obtain  proper  internal  authorization,  failure  to  comply  with 
regulatory  requirements,  information  technology  failures, 
failure to appropriately transition new hires or external events. 
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 

ARCH CAPITAL

38

2018 FORM 10-K

inadequate because of changes in conditions, or the degree of 
compliance with the policies or procedures may deteriorate. As 
a result of the inherent limitations in a cost-effective control 
system, misstatement due to error or fraud may occur and not 
be  detected.  Accordingly,  our  disclosure  controls  and 
procedures are designed to provide reasonable, not absolute, 
assurance  that  our  goals  are  met. Any  ineffectiveness  in  our 
controls or procedures could have a material adverse effect on 
our business.

We operate within an ERM framework designed to assess and 
monitor our risks. However, there can be no assurance that we 
can effectively review and monitor all risks or that all of our 
employees will operate within the ERM framework. There can 
be  no  assurance  that  our  ERM  framework  will  result  in  us 
accurately  identifying  all  risks  and  accurately  limiting  our 
exposures based on our assessments.

Our  business  is  dependent  upon  insurance  and  reinsurance 
brokers and intermediaries, and the loss of important broker 
relationships  could  materially  adversely  affect  our  ability  to 
market our products and services.

We market our insurance and reinsurance products primarily 
through  brokers  and  intermediaries.  We  derive  a  significant 
portion  of  our  business  from  a  limited  number  of  brokers. 
During  2018,  approximately  11.4%  and  9.3%  of  our  gross 
premiums  written  were  generated  from  or  placed  by  Aon 
Corporation  and  its  subsidiaries  and  Marsh &  McLennan 
Companies and its subsidiaries, respectively. No other broker 
and no one insured or reinsured accounted for more than 10% 
of gross premiums written for 2018. Some of our competitors 
have higher financial strength ratings, offer a larger variety of 
products, set lower prices for insurance coverage, offer higher 
commissions and/or have had longer term relationships with 
the brokers we use than we have. This may adversely impact 
our  ability  to  attract  and  retain  brokers  to  sell  our  insurance 
products or brokers may increasingly promote products offered 
by other companies. The failure or inability of brokers to market 
our insurance products successfully, or loss of all or a substantial 
portion of the business provided by these brokers could have a 
material adverse impact on our business, financial condition 
and results of operations. 

We  could  be  materially  adversely  affected  to  the  extent  that 
managing general agents, general agents and other producers 
exceed  their  underwriting  authorities  or  if  our  agents,  our 
insureds  or  other  third  parties  commit  fraud  or  otherwise 
breach obligations owed to us.

For  certain  business  conducted  by  our  insurance  group, 
following our underwriting, financial, claims and information 
technology  due  diligence  reviews,  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. To the extent that our agents, our insureds or 
other  third  parties  exceed  their  underwriting  authorities, 
commit fraud or otherwise breach obligations owed to us in the 
future, our financial condition and results of operations could 
be materially adversely affected.

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

for 

the  deductible  amount 

In addition to exposure to credit risk related to our investment 
portfolio, reinsurance recoverables and reliance on brokers and 
other agents (each discussed elsewhere in this section), 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 
exposed to credit risk in our insurance group’s construction and 
national  accounts  units  where  we  write  large  deductible 
insurance  policies.  Under  these  policies,  we  are  typically 
obligated  to  pay  the  claimant  the  full  amount  of  the  claim 
(shown  as  “contractholder  payables”  on  our  consolidated 
balance  sheets).  We  are  subsequently  reimbursed  by  the 
policyholder 
(shown  as 
“contractholder  receivables”  on  our  consolidated  balance 
sheets), which can be a set amount per claim and/or an aggregate 
amount for all covered claims. As such, we are exposed to credit 
risk from the 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. 
Additionally,  we  write  retrospectively  rated  policies  (i.e., 
policies in which premiums are adjusted after the policy period 
based on the actual loss experience of the policyholder during 
the policy period). In this instance, we are exposed to credit risk 
to the extent the adjusted premium is greater than the original 
premium. While we generally seek to mitigate this risk through 
collateral agreements that require the posting of collateral in 
such forms as cash and letters of credit from banks, our efforts 
to mitigate the credit risk that we have to our policyholders may 
not  be  successful.  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.

Our investment performance may affect our financial results 
and ability to conduct business.

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 (76.1% as of 
December 31,  2018).  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. Changing market 
conditions  could  materially  affect  the  future  valuation  of 
securities in our investment portfolio, which could cause us to 
impair some portion of those securities. 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 correlating 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. 
Changes  in  foreign  currency  exchange  rates  can  reduce  our 
revenues,  increase  our  liabilities  and  costs  and  cause 
fluctuations in the valuation of our investment portfolio. We 
may therefore suffer losses solely as a result of exchange rate 
fluctuations.  In  order  to  mitigate  our  exposure  to  foreign 
currency fluctuations in our net insurance liabilities, we have 
invested  and  expect  to  continue  to  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. Net foreign 
exchange  gains,  excluding  amounts  reflected  in  the  ‘other’ 
segment, were $58.7 million for 2018, compared to losses of 
$113.3 million for 2017 and gains of $31.4 million for 2016. 
Changes in the value of 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. We have chosen not to hedge certain currency risks on 
capital  contributed  to  certain  subsidiaries,  including  to Arch 
Insurance  Europe  held  in  British  Pound  Sterling,  and  may 
continue to choose not to hedge our currency risks. There can 
be  no  assurances  that  arrangements  to  match  projected 
liabilities in foreign currencies with investments in the same 

currencies or derivative financial instruments will mitigate the 
negative  impact  of  exchange  rate  fluctuations,  and  we  may 
suffer losses solely as a result of exchange rate fluctuations.

We  may  be  adversely  affected  by  changes  in  economic 
conditions, including interest rate changes.

Our operating results are affected by, and we are exposed to, 
significant financial and capital markets risk, including changes 
in interest rates, real estate values, foreign currency exchange 
rates,  market  volatility,  the  performance  of  the  economy  in 
general, the performance of our investment portfolio and other 
factors outside our control. Interest rates are highly sensitive to 
many factors, including the fiscal and monetary policies of the 
U.S.  and  other  major  economies,  inflation,  economic  and 
political  conditions  and  other  factors  beyond  our  control. 
Although we attempt to take measures to manage the risks of 
investing in changing interest rate environments, we may not 
be able to mitigate interest rate sensitivity effectively. Despite 
our mitigation efforts, an increase in interest rates could have 
a material adverse effect on our book value.

Our investment portfolio includes residential mortgage backed 
securities  (“RMBS”).  As  of  December 31,  2018,  RMBS 
constituted approximately 2.7% of cash and invested assets held 
by Arch. As with other fixed income investments, the fair value 
of these securities fluctuates depending on market and other 
general economic conditions and interest rate trends. In periods 
of  declining  interest  rates,  mortgage  prepayments  generally 
increase and RMBS are prepaid more quickly, requiring us to 
reinvest  the  proceeds  at  the  then  current  market  rates. 
Conversely, in periods of rising rates, mortgage prepayments 
generally fall, preventing us from taking full advantage of the 
higher level of rates. The residential mortgage market in the 
U.S  has  experienced  a  variety  of  difficulties  in  certain 
underwriting  periods. A  decline  or  an  extended  flattening  in 
residential property values may result in additional increases in 
delinquencies  and  losses  on  residential  mortgage  loans 
generally, especially with respect to any residential mortgage 
loans  where  the  aggregate  loan  amounts  (including  any 
subordinate  loans)  are  close  to  or  greater  than  the  related 
property values. These developments may have a significant 
adverse effect on the prices of loans and securities, including 
those  in  our  investment  portfolio  and  may  have  other  wide 
ranging  consequences,  including  downward  pressure  on 
economic growth and the potential for increased insurance and 
reinsurance exposures, which could have an adverse impact on 
our  results  of  operations,  financial  condition,  business  and 
operations.

Mortgage  insurance  losses  result  when  a  borrower  becomes 
unable to continue to make mortgage payments and the home 
of  such  borrower  cannot  be  sold  for  an  amount  that  covers 
unpaid  principal  and  interest  and  the  expenses  of  the  sale. 
Deteriorating economic conditions increase the likelihood that 
borrowers will have insufficient income to pay their mortgages 

ARCH CAPITAL

40

2018 FORM 10-K

and can adversely affect housing values. In addition, natural 
disasters or other catastrophic events could result in increased 
claims if such events adversely affected the employment and 
income  of  borrowers  and  the  value  of  homes. Any  of  these 
events or deteriorating economic conditions could cause our 
mortgage insurance losses to increase and adversely affect our 
results  of  operations  and 
financial  condition.  See 
“Management’s  Discussion  and  Analysis  of  Financial 
Condition and Results of Operations—Catastrophic Events and 
Severe Economic Events.”

Our portfolio includes commercial mortgage backed securities 
(“CMBS”).  At  December 31,  2018,  CMBS  constituted 
approximately 3.7% of cash and invested assets held by Arch. 
The  commercial  real  estate  market  may  experience  price 
deterioration, which could lead to delinquencies and losses on 
commercial real estate mortgages. 

In addition, in each year, a significant portion of our mortgage 
insurance premiums will be from mortgage insurance written 
in prior years. The length of time insurance remains in force, 
referred to as persistency, is a significant driver of mortgage 
insurance  revenues.  Factors  affecting  persistency  include: 
current  mortgage  interest  rates  compared  to  those  rates  on 
mortgages in our insurance in force, which affects the likelihood 
of the insurance in force to be subject to cancellation due to 
borrower  refinancing;  the  amount  of  home  equity,  as 
homeowners  with  more  equity  in  their  homes  can  generally 
more readily move to a new residence or refinance their existing 
mortgage;  and  mortgage  insurance  cancellation  policies  and 
practices of mortgage investors and mortgage services and the 
cancellation of borrower-paid mortgage insurance, either upon 
request of the borrower or as required by law based upon the 
amortization of the loan. In 2018, the GSEs announced changes 
to various mortgage insurance termination requirements that 
are  intended  to  further  simplify  the  process  of  evaluating 
borrower-initiated 
insurance 
termination.  Among  other  things,  these  changes  update 
evidence  of  value  requirements  for  borrower  requested 
cancellation based on the original value of the property and the 
current value of the property, raise Fannie Mae’s loan-to-value 
ratio for cancellation based on substantial improvements from 
75% or less to 80% or less, provide clarification regarding what 
constitutes  substantial  improvements  to  the  property,  allow 
servicers  to  respond  to  either  verbal  or  written  requests  for 
mortgage  insurance  cancellation  by  a  borrower,  and  provide 
servicers  flexibility  in  evaluating  the  payment  history  of 
borrowers that have been impacted by certain disaster events. 
Fannie  Mae’s  changes  in  this  area  must  be  implemented  by 
March  1,  2019,  although  certain  requirements  have  been 
implemented as early as January 1, 2019. Freddie Mac’s new 
requirements became effective October 1, 2018. If these or other 
factors cause the length of time our mortgage insurance policies 
remain in force to decline, our mortgage insurance revenues 
could be adversely affected.

Significant, continued volatility in financial markets, changes 
in  interest  rates,  a  lack  of  pricing  transparency,  decreased 
market liquidity, declines in equity prices and the strengthening 
or  weakening  of  foreign  currencies  against  the  U.S.  Dollar,

Uncertainty Relating to the Determination of LIBOR and the 
Potential  Phasing  out  of  LIBOR  after  2021  may  Adversely 
Affect  our  Cost  of  Capital,  Net  Investment  Income  and 
Mortgage Reinsurance Costs.

On  July  27,  2017,  the  U.K.  Financial  Conduct  Authority 
announced  that  it  intends  to  stop  persuading  or  compelling 
banks  to  submit  LIBOR  rates  after  2021. Accordingly,  it  is 
uncertain whether ICE, the entity responsible for administering 
LIBOR, will continue to quote LIBOR after 2021. In addition, 
in  early  2018,  the  ICE  stated  its  intention  to  continue  to 
administer and quote LIBOR after 2021, possibly employing 
an  alternative  methodology.  Therefore,  no  assurance  can  be 
given that LIBOR on any date accurately represents the London 
interbank  rate  or  the  rate  applicable  to  actual  loans  in  U.S. 
dollars for the relevant period between leading European banks, 
or that the underlying methodology for LIBOR will not change. 
Efforts  to  identify  a  set  of  alternative  U.S.  dollar  reference 
interest rates include proposals by the Alternative Reference 
Rates Committee of the Federal Reserve Board and the Federal 
Reserve Bank of New York. There is currently no definitive 
information regarding the future of LIBOR or of any particular 
replacement rate that may be established or any other reforms 
to LIBOR that may be adopted in the United Kingdom, in the 
U.S. or elsewhere.

Uncertainty  as  to  the  nature  of  such  potential  changes, 
alternative reference rates or other reforms may adversely affect 
the value of and trading market for LIBOR-based securities. 
Moreover, any future reform, replacement or disappearance of 
LIBOR  may  adversely  affect  the  value  of  and  return  of  our 
investment portfolio, our cost of capital and our cost of 
issuing Bellemeade mortgage risk transfer securities.

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

On a quarterly basis, we perform reviews of our investments to 
determine whether declines in fair value below the cost basis 
are  considered  other-than-temporary  in  accordance  with 
applicable accounting guidance regarding the recognition and 
presentation of other-than-temporary impairments. The process 
of  determining  whether  a  security  is  other-than-temporarily 
impaired  requires  judgment  and  involves  analyzing  many 
factors.  These  factors  include:  an  analysis  of  the  liquidity, 
business prospects and overall financial condition of the issuer;

the time period in which there was a significant decline in value; 
the significance of the decline; and the analysis of specific credit 
events. There can be no assurance that our management has 
accurately  assessed  the  level  of  impairments  taken  and 
allowances reflected in our financial statements. Furthermore, 
additional  impairments  may  need  to  be  taken  or  allowances 
provided  for  in  the  future.  Historical  trends  may  not  be 
indicative of future impairments or allowances. 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. Decreases in value could have a material adverse 
effect on our financial condition and results of operations.

Certain of our investments are illiquid and are difficult to sell, 
or  to  sell  in  significant  amounts  at  acceptable  prices,  to 
generate cash to meet our needs.

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 strategic investments in joint ventures such as 
Watford  Re,  Premia  Re  and  others,  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.

We may require additional capital or credit in the future, which 
may not be available or may only be available on unfavorable 
terms.

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. 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 
“Management’s  Discussion  and  Analysis  of  Financial 
Condition  and  Results  of  Operations—Financial  Condition, 
Liquidity  and  Capital  Resources—Liquidity  and  Capital 
Resources.”

The loss of our key employees or our inability to retain them 
could negatively impact our business.

Our success has been, and will continue to be, dependent on 
our ability to retain the services of our existing key executive 
officers and to attract and retain additional qualified personnel 
in the future. The pool of talent from which we actively recruit 
is  limited.  Although,  to  date,  we  have  not  experienced 
difficulties  in  attracting  and  retaining  key  personnel,  the 
inability to attract and retain qualified personnel could have a 
material adverse effect on our financial condition and results 
of operations. In addition, our underwriting staff is critical to 
our  success  in  the  production  of  business. While  we  do  not 
consider any of our key executive officers or underwriters to 
be irreplaceable, the loss of the services of our key executive 
officers or underwriters or the inability to hire and retain other 
highly qualified personnel in the future could delay or prevent 
us from fully implementing our business strategy which could 
affect our financial performance.

Our information technology systems may be unable to meet the 
demands of customers.

Our  information  technology  systems  service  our  insurance 
portfolios.  Accordingly,  we  are  highly  dependent  on  the 
effective operation of these systems. While we believe that the 
systems are adequate to service our insurance portfolios, there 
can  be  no  assurance  that  they  will  operate  in  all  manners  in 
which we intend or possess all of the functionality required by 
customers currently or in the future.

Our customers, especially our mortgage insurance customers, 
require  that  we  conduct  our  business  in  a  secure  manner, 
electronically  via 
the  Internet  or  via  electronic  data 
transmission. We must continually invest significant resources 
in  establishing  and  maintaining  electronic  connectivity  with 
customers. In order to integrate electronically with customers 
in  the  mortgage  insurance  industry,  we  require  electronic 
connections between our systems and those of the industry's 
largest mortgage servicing systems and leading loan origination 
systems. Our mortgage group currently possesses connectivity 
with certain of these external systems, but there is no assurance 
that  such  connectivity  is  sufficient  and  we  are  continually 
undertaking new electronic integration efforts with third-party 
loan servicing and origination systems. Our business, financial 
condition and operating results may be adversely affected if we 
do not possess or timely acquire the requisite set of electronic 
integrations  necessary  to  keep  pace  with  the  technological 
demands of customers.

Technology breaches or failures, including, but not limited to, 
those  resulting  from  a  malicious  cyber  attack  on  us  or  our

that  are  critical 
Furthermore,  a  significant  portion  of  the  communications 
between our employees and our business partners and service 
providers  depends  on  information  technology  and  electronic 
information  exchange.  Like  all  companies,  our  information 
technology  systems  are  vulnerable 
to  data  breaches, 
interruptions or failures due to events that may be beyond our 
control, including, but not limited to, natural disasters, power 
outages,  theft,  terrorist  attacks,  computer  viruses,  hackers, 
errors in usage and general technology failures. Additionally, 
our  employees  and  vendors  may  use  portable  computers  or 
mobile  devices  which  may  contain  duplicate  or  similar 
information to that in our computer systems, and these devices 
can be stolen, lost or damaged. Security breaches could expose 
us  to  the  loss  or  misuse  of  our  information,  litigation  and 
potential liability. In addition, cyber incidents that impact the 
availability,  reliability,  speed,  accuracy  or  other  proper 
functioning of these systems could have a significant negative 
impact  on  our  operations  and  possibly  our  results. A  cyber 
incident could also result in a violation of applicable privacy 
and  other  laws,  damage  our  reputation,  cause  a  loss  of 
customers, adversely affect our stock price, cause us to incur 
remediation costs, increased cybersecurity protection costs and/
or increased insurance premiums, and/or give rise to monetary 
fines and other penalties, any of which could be significant and 
could adversely affect our business.

We have outsourced certain technology and business process 
functions to third parties and may continue do so in the future. 
Our  outsourcing  of  certain  technology  and  business  process 
functions to third parties may expose us to increased risk related 
to data security, service disruptions or the effectiveness of our 
control system, which could result in monetary and reputational 
damage  or  harm  to  competitive  position.  These  risks  could 
increase  as  vendors  increasingly  offer  cloud-based  software 
services rather than software services which can be run within 
our data centers.

We  believe  that  we  have  established  and  implemented 
appropriate security measures to provide reasonable assurance 
that  our  information  technology  systems  are  secure  and 
appropriate controls and procedures to enable us to identify and 
respond to unauthorized access to such systems. We regularly 
engage third parties to evaluate and test the adequacy of our 
most  critical  security  measures,  controls  and  procedures. 
Despite  these  security  measures,  controls  and  procedures, 
disruptions  to  and  breaches  of  our  information  technology 

systems  are  possible.  Because  we  rely  on  our  technology 
systems for many critical functions, including connecting with 
our customers, if such systems were to fail or be attacked or 
breached,  we  may  experience  a  significant  disruption  in  our 
operations and in the business we receive and process, which 
could adversely affect our results of operations and financial 
condition.

the 

regulatory  environment 

In  addition, 
surrounding 
information security and privacy is increasingly changing. We 
are subject to EU, U.S. federal, state and other foreign laws and 
regulations  regarding  the  protection  of  personal  data  and 
information.  These  laws  and  regulations  are  complex  and 
sometimes conflict. We could be subject to fines, penalties and/
or regulatory enforcement actions in one or more jurisdictions 
if any person, including any employee, disregards or breaches, 
whether  intentionally  or  negligently,  controls  intended  to 
protect the confidential information of our employees or clients. 
As an example, the New York State Department of Financial 
Services adopted a regulation pertaining to cybersecurity for 
all  banking  and  insurance  entities  under  its  jurisdiction  that 
came into effect March 1, 2017. Additionally, GDPR came into 
effect on May 25, 2018, and requires businesses offering goods 
and services to, or monitoring the behavior of, customers in the 
EU  to  comply  with  onerous  accountability  obligations  and 
significantly enhanced conditions to processing personal data. 
Non-compliance with the GDPR could result in a fine of up to 
4% of a firm’s global annual revenue per violation. As a result, 
our ability to conduct our business and our results of operations 
might be materially and adversely affected.

If  the  volume  of  low  down  payment  mortgage  originations 
declines, 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. A decline in the volume of low down payment home 
mortgage  originations  could  decrease  demand  for  mortgage 
insurance, decrease our U.S. new insurance written and reduce 
mortgage insurance revenues.

If the role of the GSEs in the U.S. housing market changes, or 
if the GSEs change other policies or practices, the amount of 
mortgage insurance that we write could decline, which would 
reduce our mortgage insurance revenues.

The GSEs are the beneficiaries of the significant majority of 
the insurance policies we issue as a result of their purchases, 
statutorily required or otherwise, of qualifying mortgage loans 
from  lenders  or  investors. The  charters  of  the  GSEs  require 
credit enhancement for low down payment mortgages in order 
for such loans to be eligible for purchase or guarantee by the 
GSEs. 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.

The premiums we charge for mortgage insurance on insured 
loans  and  the  associated  investment  income  may  not  be 
adequate to compensate for future losses from these loans.

We set premiums at the time a policy is issued based upon our 
expectations  regarding  likely  performance  over  the  life  of 
insurance  coverage.  We  generally  cannot  cancel  mortgage 
insurance coverage or adjust renewal premiums during the life 
of a mortgage insurance policy. As a result, losses from higher 
than anticipated claims generally cannot be offset by premium 
increases on policies in force or mitigated by non-renewal or 
cancellation of insurance coverage. The premiums we charge 
on our insurance in force and the associated investment income 
may not be adequate to compensate us for the risks and costs 
associated with the insurance coverage provided to customers. 
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.

New GSE eligibility requirements for mortgage insurers could 
require us to contribute additional capital to Arch MI U.S. in 
the future, and 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 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,  procedures  for  claims  handling, 
acceptable  underwriting  practices,  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  of  an  insurer,  to  meet  or  exceed  “minimum  required 
assets” as of each quarter end. Our eligible mortgage insurers 
each  satisfied  the  PMIERs’  financial  requirements  as  of 
December 31, 2018. 

The  revised  PMIERs  also  impose  additional  operational 
requirements in areas such as claim processing, loss mitigation, 
underwriting,  quality  control,  and  reporting.  The  revised 
requirements have caused us to make changes to our business 
practices  and  incur  additional  costs  in  order  to  achieve  and 
maintain compliance with the PMIERs. While we do not expect 
the  revised  PMIERs  to  have  a  significant  impact  on  our 
operations  or  a  material  impact  on  our  capital  position  the 
increase in capital required to satisfy the revised PMIERs may 
decrease our return on capital.

While we intend to continue to comply with these requirements, 
there can be no assurance that the GSEs will continue to treat 
Arch  Mortgage  Insurance  Company  or  United  Guaranty 
Residential Insurance Company 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 mix of business we write affects Arch MI U.S.’s losses and 
will affect the minimum required assets Arch MI U.S. is required 
to  maintain  in  order  to  comply  with  PMIERs  financial 
requirements.

Our mortgage insurance portfolio includes loans with loan-to-
value ratios exceeding 95%, loans with FICO scores below 620, 
adjustable rate mortgages, (“ARMs”), and less-than A quality 
loans. Even when housing values are stable or rising, we expect 
higher  default  and  claim  rates  for  high  loan-to-value  loans, 
loans with lower FICO scores, ARMs and less-than A quality 
loans. Although we attempt to incorporate the higher default 
and  claim  rates  associated  with  these  loans  into  our 
underwriting and pricing models, there can be no assurance that 
the premiums earned and the associated investment income will 
adequately compensate us for future losses from these loans. 
From time to time, we change the types of loans that we insure 
and the requirements under which we insure them. In 2017 and 
2018, we modestly expanded our underwriting guidelines and 
we may further expand such guidelines in the future.

The geographic mix of Arch MI U.S.’s business could increase 
losses and harm our financial performance. We are affected by 
economic downturns and other events in specific regions of the 
United  States  where  a  large  portion  of  our  U.S.  mortgage 
insurance business is concentrated. As of December 31, 2018, 
7.7% of Arch MI U.S.’s primary risk-in-force was located in 
Texas, 6.3% was located in California and 5.0% was located in 
Florida.  See  “Management’s  Discussion  and  Analysis  of 
Financial  Condition  and  Results  of  Operations—Critical 
Accounting  Policies,  Estimates  and  Recent  Accounting 
Pronouncements—Mortgage  Operations

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.

Potential  changes  to  state  mortgage  insurance  regulations 
could  reduce  Arch  MI  U.S.’s  profitability  and  its  ability  to 
compete  with  credit  enhancement  alternatives  to  mortgage 
insurance.

The NAIC, which reviews state insurance laws and regulations, 
has established a Mortgage Guaranty Insurance Working Group 
(“Working Group”) to make recommendations to the NAIC's 
Financial  Condition  Committee  regarding  changes  to  the 
NAIC’s  Mortgage  Guaranty  Insurance  Model  Act.  The 
Working Group has released a drafts of the Model Act which 
includes  proposed  changes  to  minimum  statutory  capital 
requirements.

If the NAIC revises the Model Act, some state legislatures are 
likely  to  enact  and  implement  part  or  all  of  the  revised 
provisions. While we cannot predict the effect that any NAIC 
recommendations or future legislation may have on Arch MI 
U.S., such changes could reduce Arch MI U.S.’s profitability 
and its ability to compete with credit enhancement alternatives 
to  mortgage  insurance,  which  could  adversely  affect  our 
financial condition or results of operations.

If servicers fail to adhere to appropriate servicing standards or 
experience  disruptions  to  their  businesses,  our  mortgage 
insurance operations could be adversely affected.

We depend on reliable, consistent third-party servicing of the 
loans  that  we  insure.  Among  other  things,  our  mortgage 
insurance policies require our customers and their servicers to 
timely submit premium and reports and utilize commercially 
reasonable efforts to limit and mitigate loss when a loan is in 
default. Without reliable, consistent third-party servicing, our 
insurance subsidiaries may be unable to correctly record new 
loans as they are underwritten, receive and process payments 
on  insured  loans  and/or  properly  recognize  and  establish 
reserves  on  loans  when  a  default  exists  or  occurs  but  is  not 
reported to us. In addition, if these servicers fail to limit and 
mitigate losses when appropriate, our losses may unexpectedly 
increase.  If  one  or  more  servicers  failed  to  adhere  to  these 
requirements, our financial results could be adversely affected.

The  implementation  of  the  Basel  III  Capital  Accord  may 
adversely affect the use of mortgage insurance by certain banks.

With certain exceptions, the Basel III Rules became effective 
on January 1, 2014. If further implementation of the Basel III 

ratio  at 

increases

loan-to-value 

Rules 
requirements  of  banking 
organizations  with  respect  to  the  residential  mortgages  we 
insure or does not provide sufficiently favorable treatment for 
the  use  of  mortgage  insurance,  it  could  adversely  affect  the 
demand for mortgage insurance. In December 2017, the Basel 
Committee  published  final  revisions  to  the  Basel  Capital 
Accord that will be implemented by each participating country 
by January 1, 2022. Under these revised rules, 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. Under the standardized 
approach, after the appropriate risk-weight is determined, the 
existence of mortgage insurance could be considered, but only 
if the company issuing the insurance has a lower risk-weight 
than the underlying exposure. Mortgage insurance issued by 
private companies would not meet this test. Therefore, under 
the latest Basel Capital Accord, mortgage insurance could not 
mitigate  credit  and  lower  the  capital  charge  under  the 
standardized  approach.  If  the  Basel  Capital  Accord  is 
implemented  in  the  United  States  in  this  form,  mortgage 
insurance would not lower the loan-to-value ratio of residential 
loans  for  capital  purposes,  and  therefore  may  decrease  the 
demand for this product. It is possible that the U.S. regulatory 
agencies could determine that their current capital rules are at 
least as stringent as the Basel Committee’s 2017 revisions, in 
which case no change would be mandated. However, if the U.S. 
agencies decide to implement the new standards as specifically 
drafted by the Basel Committee, mortgage insurance would not 
lower  the  loan-to-value  ratio  of  residential  loans  for  capital 
purposes,  and  therefore  may  decrease  the  demand  for  this 
product.

Further, it is possible (but not mandated by the Basel Capital 
Accord) that the banking agencies and the GSEs might likewise 
discontinue  taking  mortgage  insurance  into  account  when 
determining  a  mortgage’s  loan-to-value  ratio  for  prudential 
(non-capital) purposes. Additionally, a new riskbased capital 
proposal for the GSEs was published for comment by the FHFA 
in 2018. Under this proposal the capital requirements of these 
GSEs would take into account the existence of credit mitigants, 
such as mortgage insurance. However, as proposed, mortgage 
insurance issued by monoline companies would result in less 
capital relief than the capital relief afforded by other forms of 
credit mitigation, such as the issuance of credit-linked notes. 
The final form ofthe rule is likely to change based on comments 
received from industry participants and the views of the new 
director of the FHFA. However, if adopted as proposed, these 
capital regulations might incent the GSEs to favor these forms 
of credit risk mitigation when they have the option to use these 
instruments.If  these  developments  should  occur,  they  would 
adversely affect the demand for mortgage insurance in the U.S. 
which  would  adversely  affect  our  U.S.  mortgage  insurance 
operations.

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 to a 15% Holder; or amendment of these provisions; 
provided, however, the supermajority vote will not apply to any 
transaction approved by the board.

Among  other  things,  our  bye-laws  provide:  for  a  classified 
board of directors, 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 our 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 our 
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 
which 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) 

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 could also result in the 
entrenchment of incumbent management.

There are regulatory limitations on the ownership and transfer 
of our common shares.

The  jurisdictions  in  which  our  insurance  and  reinsurance 
subsidiaries  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 and 
our subsidiaries, there can be no effective change in our control 
unless the person seeking to acquire control has filed a statement 
with  the  regulators  and  has  obtained  prior  approval  for  the 
proposed change from such regulators. The usual measure for 
a presumptive change in control pursuant to these laws is the 
acquisition of 10% or more of the voting power of the insurance 
company or its parent, although this presumption is rebuttable. 
Consequently, a person may not acquire 10% or more of our 
common  shares  without  the  prior  approval  of  the  applicable 
insurance  regulators.  These  laws  may  discourage  potential 
acquisition proposals and may delay, deter or prevent a change 
in control of us, including transactions that some shareholders 
might consider to be desirable.

Our  insurance  and  reinsurance  subsidiaries  are  subject  to 
regulation in various jurisdictions, and failure to comply with 
existing regulations or material changes in the regulation of 
their operations, or any investigations, inquiries or demands 
by government authorities, could adversely affect us.

Our insurance and reinsurance subsidiaries are subject to the 
laws and regulations of a number of jurisdictions worldwide,

subsidiaries conduct business, the U.K., certain EU Member

our business operations through acquisitions or to pay dividends 
on our ordinary shares. Furthermore, compliance with legal and 
regulatory  requirements  may  result  in  significant  expenses, 
which could have a negative impact on our profitability. 

these 

In addition to legal and regulatory requirements, the insurance 
and reinsurance industry has experienced substantial volatility 
as a result of investigations, litigation and regulatory activity 
by  various 
insurance,  governmental  and  enforcement 
authorities,  including  the  SEC,  concerning  certain  practices 
within the insurance and reinsurance industry. Our involvement 
in  any  investigations,  litigations  or  regulatory  activity, 
including any related lawsuits, would cause us to incur legal 
costs  and,  if  we  or  any  of  our  insurance  or  reinsurance 
subsidiaries  were  found  to  have  violated  any  laws  or 
regulations, we could be required to pay fines and damages and 
incur other sanctions, perhaps in material amounts, which could 
have a material negative impact on our profitability. 

Any such litigation or failure to comply with applicable laws 
could result in the imposition of significant restrictions on our 
ability  to  do  business,  and  could  also  result  in  suspensions, 
injunctions, monetary damages, fines or other sanctions, any or 
all of which could adversely affect our financial condition and 
results of operations.

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.

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 dependent on their ability to meet applicable 
regulatory standards. In addition, the ability of our insurance 
and reinsurance subsidiaries to pay dividends to Arch Capital 
and to intermediate parent companies owned by Arch Capital 
could be constrained by our dependence on financial strength 
ratings  from  independent  rating  agencies.  Our  ratings  from 
these agencies depend to a large extent on the capitalization 
levels of our 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.  See  “Management’s  Discussion  and 
Analysis of Financial Condition and Results of Operations—
Financial  Condition,  Liquidity  and  Capital  Resources—
Liquidity and Capital Resources.”

The service of process and enforcement of judgments against 
us or our directors or officers may be difficult.

We  are  a  Bermuda  company  and  some  of  our  officers  and 
directors are residents of various jurisdictions outside the U.S. 
All or a substantial portion of our assets and the assets of those 
persons may be located outside the U.S. As a result, it may be 
difficult for investors to effect service of process within the U.S. 
upon those persons or to recover against us or those persons on 
judgments of U.S. courts based on civil liabilities provisions of 
the U.S. federal securities laws even though we have appointed 
National Registered Agents, Inc., New York, New York, as our 

ARCH CAPITAL

47

2018 FORM 10-K

agent for service of process with respect to actions based on 
offers and sales of securities made in the U.S. Because there is 
no treaty in effect between the U.S. and Bermuda providing for 
reciprocal recognition and enforcement of judgments of U.S. 
courts in civil and commercial matters, a final judgment for the 
payment of money rendered by a court in the U.S. based on 
civil liability, whether or not predicated solely upon the U.S. 
federal securities laws, would not be automatically enforceable 
in Bermuda, and there are grounds upon which Bermuda courts 
may not enforce judgments of U.S. courts. Further, no claim 
may  be  brought  in  Bermuda  against  us  or  our  directors  and 
officers for violation of U.S. federal securities laws, as such 
laws do not have force of law in Bermuda. A Bermuda court 
may, however, impose civil liability on us or our directors and 
officers in a suit brought in the Supreme Court of Bermuda if 
the facts alleged in the complaint constitute or give rise to a 
cause of action under Bermuda law.

Our international business is subject to applicable laws and 
regulations relating to sanctions and foreign corrupt practices, 
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,  including  the  U.K.  and  the 
European Community. U.S. laws and regulations applicable to 
us 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. In addition, we are subject to the 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  that  are 
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 such event, we 
could be exposed to civil penalties, criminal penalties and other 
sanctions, including fines or other punitive actions. In addition, 
such  violations  could  damage  our  business  and/or  our 
reputation.  Such  criminal  or  civil  sanctions,  penalties,  other 
sanctions, and damage to our business and/or reputation could 
have a material adverse effect on our financial condition and 
results of operations.

Risk Relating to Our Shares

The  market  price  of  our  common  shares  may  experience 
volatility,  thereby  causing  a  potential  loss  of  value  to  our 
investors.

The  market  price  for  our  common  shares  may  fluctuate 
substantially and could cause investment losses. The price of 
our common shares may not remain at or exceed current levels. 

In addition to the risk factors described herein, the following 
factors may have an adverse impact on the market price for our 
common shares: announcements by us or our competitors of 
acquisitions, investments or strategic alliances; changes in the 
value  of  our  assets;  our  actual  or  anticipated  quarterly  and 
annual  operating  results;  changes  in  expectations  of  future 
financial  performance  or  changes  in  estimates  of  securities 
analysts; issuances by us of shares or other securities; sales, or 
the  possibility  or  perception  of  future  sales,  by  our  existing 
shareholders; our share repurchase program; changes in general 
conditions  in  the  economy,  the  insurance  industry  or  the 
financial markets; changes in market valuation of companies 
in the insurance and reinsurance industry; fluctuations in stock 
market processes and volumes; the addition or departure of key 
personnel;  changes  in  tax  law;  and  adverse  press  or  news 
announcements affecting us or the industry.

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,  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 Arch Capital's board of 
directors (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 its board of directors (or a duly authorized 
committee of the board) has not declared such dividend before 
the related dividend payment date; if dividends on our series E 
or series F preferred shares are authorized and declared with 
respect to any subsequent dividend period, Arch Capital will be 

ARCH CAPITAL

48

2018 FORM 10-K

free to pay dividends on any other series of preferred shares 
and/or  our  common  shares.  In  the  past,  we  have  not  paid 
dividends on our common shares.

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

Our preferred shares are equity interests and do not constitute 
indebtedness. As such, these preferred shares will rank junior 
to  all  of  our  indebtedness  and  other  non-equity  claims  with 
respect to assets available to satisfy our claims, including in our 
liquidation. As of December 31, 2018, our total long-term debt 
was $1.73 billion, excluding the ‘other’ segment. We may incur 
additional  debt  in  the  future.  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  of 
directors of Arch Capital (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.

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 E or series F 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 E or series F preferred shares 
will  be  entitled  to  vote  for  the  election  of  two  additional 
directors to our board of directors subject to the terms and to 
the limited extent as set forth in the certificate of designations 
relating to such series of preferred shares.

There is no limitation on our issuance of securities that rank 
equally with or senior to our preferred shares.

We may issue additional securities that rank equally with or 
senior  to  our  series  E  and  series  F  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.

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.

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  taxes  on  insurance  and  reinsurance  premium  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 assurances 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. If 
Arch Capital or any of its non-U.S. subsidiaries were subject 
to U.S. income tax, 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. insurance companies. There is no 
assurance that any such legislative proposal will not be enacted 
into law and any such enacted law would not adversely affect 
income tax liabilities of us or any of our subsidiaries.

The newly enacted U.S. tax law and its implementation may 
have  a  material  and  adverse  impact  on  our  operations  and 
financial condition. 

The Tax Cuts Act includes significant changes to the taxation 
of business entities. These changes include, among others, a 
permanent  reduction  to  the  corporate  income  tax  rate. 
Notwithstanding the reduction in the corporate income tax rate, 
the  overall  impact  of  this  tax  reform  is  uncertain,  and  our 
business  and  financial  condition  could  be  materially  and 
adversely affected.

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 tax 
(reduced to 5% for the 2018 taxable year and increased to 12.5% 
for the 2026 taxable year and the subsequent taxable years) 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). The reinsurance agreements 
between  our  U.S.-based  property  casualty  insurance  and 
reinsurance subsidiaries and Arch Re Bermuda were canceled 
on a cutoff basis as of January 1, 2018. As such, the level of 

ARCH CAPITAL

49

2018 FORM 10-K

subject business ceded to Arch Re Bermuda was substantially 
lower in 2018 than in prior periods. 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. There is no assurance that 
subsequent change in tax laws will materially and adversely 
affect our operations and financial condition.

Our non-U.K. companies may be subject to U.K. tax that may 
have a material adverse effect on our results of operations.

We  intend  to  operate  in  such  a  manner  so  that  none  of  our 
companies,  other  than  our  U.K.  subsidiaries  and  branch 
operations (the “U.K. Group”), should be resident in the U.K. 
for tax purposes or carry on a trade, whether or not through a 
permanent establishment, in the U.K. Accordingly, we do not 
expect that any of our other subsidiaries, other than the U.K. 
Group, should be subject to U.K. tax. Case law has held that 
whether or not a trade is being carried on in the U.K. is a matter 
of fact and emphasis is placed on where the operations take 
place from which the profits in substance arise. HM Revenue 
and Customs might contend successfully that one or more of 
our subsidiaries, in addition to the U.K. Group, is carrying on 
a  trade  in  the  U.K.  For  U.K.  tax  purposes,  a  non-U.K.  tax 
resident company will be subject to U.K. corporation tax only 
if it carries on a trade through a permanent establishment in the 
U.K.  However,  that  subsidiary  may  still  be  subject  to  U.K. 
income  tax  if  it  carries  on  a  trade  in  the  U.K.,  without  a 
permanent establishment, unless it is entitled to the protection 
afforded  by  a  double  tax  treaty  between  the  U.K.  and  the 
jurisdiction in which that company is resident. If any of our 
subsidiaries is treated as resident, or carrying on a trade, in the 
U.K., whether or not through a permanent establishment, and, 
therefore, subject to U.K. tax, our results of operations could 
be materially adversely affected.

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. We could be subject to taxes in Bermuda after 
that  date.  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.

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.

The Organization for Economic Cooperation and Development 
(“OECD”)  has  published  reports  and  launched  a  global 
initiative  among  member  and  non-member  countries  on 
measures to limit harmful tax competition. These measures are 
largely directed at counteracting the effects of tax havens and 
preferential tax regimes in countries around the world. Bermuda 
was not listed in the most recent report as an uncooperative tax 
haven  jurisdiction  because  it  had  previously  committed  to 
eliminate harmful tax practices, to embrace international tax 
standards  for  transparency,  to  exchange  information  and  to 
eliminate  an  environment  that  attracts  business  with  no 
substantial  domestic  activity.  We  are  not  able  predict  what 
changes  will  arise  from  the  commitment  or  whether  such 
changes will subject us to additional taxes.

The  impact  of  commitments  made  by  the  government  of 
Bermuda in order to avoid being named on the EU’s list of non-
cooperative tax jurisdictions is uncertain and could have an 
adverse effect on our results of operations.

Following a year-long screening process, on December 5, 2017 
the Council of the European Union published its list of non-
cooperative jurisdictions for tax purposes (the “EU Blacklist”). 
Bermuda  was  not  named  on  the  EU  Blacklist  due  to 
commitments  made  by  its  government  to  improve  certain 
“substance requirement” deficiencies that were identified by 
the EU during the screening process. This commitment led to

the  passing  of  the  Economic  Substance  Act  2018  (the 
“Substance  Act”)  in  December  2018.  The  Substance  Act 
requires certain entities resident in Bermuda to demonstrate that 
they have adequate economic substance in Bermuda. Broadly, 
this is expected to be the case where an entity can demonstrate 
it  has  adequate  income  generating  activities,  employees, 
premises, and expenditure incurred in Bermuda, although the 
meaning of "adequate" in this context remains unclear. Further, 
the speed with which the Substance Act was implemented, and 
the uncertainties in its interpretation, make it difficult to predict 
its  future  impact. 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). The EU is expected to announce whether 
the  Substance Act  is  sufficient  to  keep  Bermuda  off  the  EU 
Blacklist  in  February  2018.  The  nature  and  scope  of  the 
sanctions  that  may  be  applied  as  a  result  of  Bermuda  being 
included in the EU Blacklist is still being considered. Sanctions 
that the EU has recommended Member States adopt include, 
inter alia, increased auditing of taxpayers using structures or 
arrangements involving listed jurisdictions and the imposition

The EU’s review of harmful tax competition could adversely 
affect  our  business,  financial  condition  and  results  of 
operations.

During 2017, the EU Economic and Financial Affairs Council 
(“ECOFIN”) released a list of noncooperative jurisdictions for 
tax  purposes. The  stated  aim  of  this  list,  and  accompanying 
report, was to promote good governance worldwide in order to 
maximize efforts to prevent tax fraud and tax evasion. Bermuda 
was  not  on  the  list  of  non-cooperative  jurisdictions,  but  did 
feature  in  the  report  (along  with  approximately  40  other 
jurisdictions) as having committed to address concerns relating 
to economic substance by December 31, 2018. In accordance 
with that commitment, Bermuda has enacted legislation that 
requires  certain  entities  in  Bermuda  engaged  in  “relevant 
activities”  to  maintain  a  substantial  economic  presence  in 
Bermuda and to satisfy economic substance requirements. The 
list of “relevant activities” includes carrying on as a business 
any  one  or  more  of:  banking,  insurance,  fund  management, 
financing,  leasing,  headquarters,  shipping,  distribution  and 
service center, intellectual property and holding entities. Any 
entity that must satisfy economic substance requirements but 
fails  to  do  so  could  face  automatic  disclosure  to  competent 
authorities in the EU of the information filed by the entity with 
the Bermuda Registrar of Companies in connection with the 
economic substance requirements and may also face financial 
penalties, restriction or regulation of its business activities and/
or may be struck off as a registered entity in Bermuda.

At  present,  the  impact  of  these  new  economic  substance 
requirements is unclear, and it is impossible to predict the nature 
and  effect  of  these  requirements  on  us.  The  new  economic 
substance requirements may increase the complexity and costs 
of carrying on our business and adversely affect our financial 
condition and results of operations.

of withholding taxes on payments made to such jurisdictions. 
As a result, there is a risk that both the adoption of the Substance 
Act, possible further legislative changes, and the imposition of 
sanctions  in  circumstances  where  Bermuda  is  ultimately 
included  on  the  EU  Blacklist,  could  result  in  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 international tax standards have not 
kept pace with changes in global business practices and 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 
October 2015, the OECD issued “final reports” in connection 
with  the  BEPS  project. The  final  reports  were  approved  for 
adoption by the G20 finance ministers in November 2015. 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). 

Legislation  to  adopt  these  standards  has  been  enacted  or  is 
currently under consideration in a number of jurisdictions to 
implement  these  standards,  including  country  by  country 
reporting. 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 adoption of these standards may increase the 
complexity  and  costs  associated  with  tax  compliance  and 
adversely affect our financial position and results of operations.

GENERAL

Overview

Arch Capital Group Ltd. (“Arch Capital” and, together with its 
subsidiaries, “we” or “us”) is a Bermuda public limited liability 
company  with  approximately  $11.17  billion  in  capital  at 
December 31, 2018 and, through operations in Bermuda, the 
United  States,  Europe  and  Canada,  writes  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 which a hard market (high premium 
rates, restrictive underwriting standards, as well as terms and 
conditions, and underwriting gains) is eventually followed by 
a  soft  market  (low  premium  rates,  relaxed  underwriting 
standards,  as  well  as  broader  terms  and  conditions,  and 
underwriting losses). Property casualty market conditions 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.

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.

Current Outlook

Our  objective  is  to  achieve  an  average  operating  return  on 
average  equity  of  15%  or  greater  over  the  insurance  cycle, 
which  we  believe  to  be  an  attractive  return  to  our  common 
shareholders given the risks we assume. We continue to look 
for  opportunities  to  find  acceptable  books  of  business  to 
underwrite  without  sacrificing  underwriting  discipline  and 
continue to write a portion of our overall book in catastrophe-
exposed  business  which  has  the  potential  to  increase  the 
volatility of our operating results.

The  broad  property  casualty  insurance  market  environment 
continues to be competitive, with only a few specialty areas 
providing opportunities to deploy capital at returns which meet 
our risk-adjusted return requirements. In most of our insurance 
lines of business, rate increases appear to be in excess of loss 
cost trends. However, the spread between rate changes and loss 
trend  is  a  key  variable  in  assessing  expected  returns  and,  in 
specialty lines, is volatile by nature. Our underwriting teams 
continue to execute a disciplined strategy by emphasizing small 
and  medium-sized  accounts  over  large  accounts,  shrinking 
premiums in more commoditized lines such as general liability 
and  directors  and  officers,  and  by  utilizing  reinsurance 
purchases to reduce volatility on large account, high capacity 
business.  Writings  in  property  catastrophe-exposed  business 
continued to remain low in 2018. 

Our  mortgage  segment  continues  to  experience  generally 
favorable market conditions, with pricing in the U.S. stabilizing 
in the third quarter following the rate changes announced in the 
first half of 2018. Our results continue to reflect our success in 
making  high  quality  credit  underwriting  risk  decisions  and 
building customer relationships.

Arch remains committed to providing solutions across many 
offerings as the marketplace evolves, including new mortgage 
credit risk transfer programs initiated by government sponsored 
enterprises, or “GSEs,” in 2018. Such programs have begun 
generating  business  with  banks  developing  new  systems  to 
handle  the  programs  and  momentum  beginning  to  build.  In

addition, we completed multiple Bellemeade risk transfers to 
the capital markets throughout 2018, increasing our protection 
for mortgage tail risk.

FINANCIAL MEASURES

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

Book Value per Share

and 

common 

Book value per share represents total common shareholders’ 
equity  available  to Arch  divided  by  the  number  of  common 
shares 
equivalents  outstanding. 
share 
Management  uses  growth  in  book  value  per  share  as  a  key 
measure of the value generated for our common shareholders 
each period and believes that book value per share is the key 
driver of Arch Capital’s share price over time. Book value per 
share  is  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 
$21.52 at December 31, 2018, a 6.0% increase from $20.30 at 
December 31,  2017.  The  growth  in  2018  reflected  strong 
underwriting results, partially offset by the impact of an increase 
in interest rates on our fixed income securities.

Operating Return on Average Common Equity

Operating  return  on  average  common  equity  (“Operating 
ROAE”)  represents  annualized  after-tax  operating  income 
available  to Arch  common  shareholders  divided  by  average 
common  shareholders’  equity  available  to  Arch  during  the 
period. After-tax operating income available to Arch common 
shareholders, a “non-GAAP measure” as defined in the SEC 
rules,  represents  net  income  available  to  Arch  common 
shareholders,  excluding  net  realized  gains  or  losses,  net 
impairment losses recognized in earnings, equity in net income 
or loss of investments accounted for using the equity method, 
net foreign exchange gains or losses and transaction costs and 
other, net of income taxes. Management uses Operating ROAE 
as  a  key  measure  of  the  return  generated  to Arch  common 
shareholders.  See  “Comment  on  Non-GAAP  Financial 
Measures.”  Our  Operating  ROAE  was  10.7%  for  2018, 
compared  to  5.7%  for  2017  and  9.4%  for  2016. The  higher 
Operating ROAE for 2018 reflected strong mortgage insurance 
underwriting  performance,  while  2017  returns  reflected  a 
higher level of catastrophic loss activity.

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 and losses and the change in 

unrealized  gains  and  losses  generated  by Arch’s  investment 
portfolio. Total return is calculated on a pre-tax basis and 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 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.

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

expenses):

and  0.34%,  respectively,  of  average  invested  assets  in  2018, 
2017 and 2016.

Total return for our investment portfolio outperformed that of 
the  benchmark  return  index  in  2018,  reflecting  strong 
performance  from  our  alternative  investments.  Excluding 
foreign exchange, total return was 1.13% for 2018, compared 
to 4.98% for 2017 and 2.35% for 2016. Total return for 2018 
reflected the impact of rising interest rates and widening credit 
spreads,  which  dampened  the  total  return  on  our  investment 
grade fixed income portfolio, and negative returns on equities.

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 index should not 
be 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, 2018, the benchmark 
return index had an average credit quality of “Aa2” by Moody’s, 
an estimated duration of 3.23 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, net impairment losses recognized 
in  earnings,  equity  in  net  income  or  loss  of  investments 
accounted for using the equity method, net foreign exchange 
gains or losses, transaction costs and other, loss on 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 
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,  net  impairment 
losses recognized in earnings, equity in net income or loss of 
investments accounted for using the equity method, net foreign 

impairment 

losses  recognized 

represent  other-than-temporary  declines 

exchange gains or losses, transaction costs and other and loss 
on redemption of preferred shares in any particular period are 
not indicative of the performance of, or trends in, our business. 
Although net realized gains or losses, net impairment losses 
recognized  in  earnings,  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 investment gains or losses, 
the  recognition  of  the  change  in  the  carrying  value  of 
investments  accounted  for  using  the  fair  value  option  in  net 
realized  gains  or  losses,  the  recognition  of  net  impairment 
losses,  the  recognition  of  equity  in  net  income  or  loss  of 
investments  accounted  for  using  the  equity  method  and  the 
recognition of foreign exchange gains or losses are independent 
of the insurance underwriting process and result, in large part, 
from  general  economic  and  financial  market  conditions. 
Furthermore, certain users of our financial information believe 
that,  for  many  companies,  the  timing  of  the  realization  of 
investment gains or losses is largely opportunistic. In addition, 
in  earnings  on  our 
net 
investments 
in 
expected  recovery  values  on  securities  without  actual 
realization.  The  use  of  the  equity  method  on  certain  of  our 
investments  in  certain  funds  that  invest  in  fixed  maturity 
securities is driven by the ownership structure of such funds 
(either limited partnerships or limited liability companies). In 
applying  the  equity  method,  these  investments  are  initially 
recorded at cost and are subsequently adjusted based on our 
proportionate 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 fixed maturity securities 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.  Transaction  costs  and  other  include  advisory, 
financing, legal, severance, incentive compensation and other 
transaction  costs  related  to  acquisitions,  including  UGC. 
During  the  2016  fourth  quarter,  transaction  costs  and  other 
included non-recurring expenses related to a change in the our 
approach on the deferral of certain internal underwriting costs 
which are no longer being deferred. 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 our Series C preferred shares in September 
2017  and  January  2018  and  had  no  impact  on  shareholders' 
equity  or  cash  flows.  Due  to  these  reasons,  we  exclude  net 
realized gains or losses, net impairment losses recognized in 
earnings, equity in net income or loss of investments accounted 
for  using  the  equity  method,  net  foreign  exchange  gains  or 
losses, transaction costs and other and loss on redemption of 
preferred  shares  from  the  calculation  of  after-tax  operating 
income available to Arch common shareholders. In addition, 
income tax expense for 2017 included a $21.5 million charge

due to the revaluation of the Company’s net deferred tax asset 
resulting from the reduction in the U.S. corporate income tax 
rate from 35% to 21% effective January 1, 2018. Due to the 
non-recurring nature of this item, we excluded it from after-tax 
operating income available to Arch common shareholders.

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

the  presentation  of 
Our  segment 
consolidated  underwriting  income  or  loss  and  a  subtotal  of 
underwriting income or loss before the contribution from the 
‘other’  segment.  Such  measures  represent 
the  pre-tax 
profitability  of  our  underwriting  operations  and  include  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 
individual  underwriting  operations. 
attributable 
Underwriting  income  or  loss  does  not  incorporate  items 
included in our corporate (non-underwriting) segment. While 
these measures are presented in note 4, “Segment Information,” 
to  our  consolidated  financial  statements  in  Item  8,  they  are 
considered  non-GAAP  financial  measures  when  presented 
elsewhere  on  a  consolidated  basis.  The  reconciliations  of 
underwriting income or loss to income before income taxes (the 
most  directly  comparable  GAAP  financial  measure)  on  a 
consolidated basis and a subtotal before the contribution from 
the ‘other’ segment, in accordance with Regulation G, is shown 
in note 4, “Segment Information,” to our consolidated financial 
statements in Item 8.

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

Along with consolidated underwriting income, we provide a 
subtotal of underwriting income or loss before the contribution 
from  the  ‘other’  segment.  Pursuant  to  generally  accepted 
accounting  principles,  Watford  Re  is  considered  a  variable 
interest  entity  and  we  concluded  that  we  are  the  primary 
beneficiary of Watford Re. As such, we consolidate the results 
of  Watford  Re  in  our  consolidated  financial  statements, 
although  we  only  own  approximately  11%  of  Watford  Re’s 
common equity. Watford Re has its own management and board 
of directors that is responsible for its overall profitability. In 
addition,  we  do  not  guarantee  or  provide  credit  support  for 
Watford Re. Since Watford Re is an independent company, the 
assets of Watford Re can be used only to settle obligations of 
Watford Re and Watford Re is solely responsible for its own 
liabilities and commitments. Our financial exposure to Watford 
Re is limited to our investment in Watford Re’s common and 
preferred  shares  and  counterparty  credit  risk  (mitigated  by 
collateral) arising from the reinsurance transactions. We believe 
that  presenting  certain  information  excluding  the  ‘other’ 
segment  enables  investors  and  other  users  of  our  financial 
information to analyze our performance in a manner similar to 
how our management analyzes performance.

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 and losses and the change in 
unrealized  gains  and  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.

2018  versus  2017:  Net  premiums  written  by  the  insurance 
segment were 4.2% higher in 2018 than in 2017. The increase 
in net premiums written reflected growth in travel, due to both 
new business and growth in existing accounts, and in property, 
primarily  due  to  new  business  and  rate  increases.  These 
increases were partially offset by a reduction in contract binding 
and accident and health in response to market conditions.

2017  versus  2016:  Net  premiums  written  by  the  insurance 
segment were 2.4% higher in 2017 than in 2016. The increase 
in net premiums written reflected growth in programs, due to 
the continued effects of two newer programs, in travel, accident 
and health, reflecting both new travel business and continued 
expansion in existing travel accounts, and in professional lines, 
reflecting increases in small and medium sized accounts. Such 
amounts  were  partially  offset  by  a  reduction  in  excess  and

Current Year Loss Ratio. 

2018 versus 2017: The insurance segment’s current year loss 
ratio was 7.2 points lower in 2018 than in 2017. The 2018 loss 
ratio  included  3.4  points  of  current  year  catastrophic  event 
activity, primarily related to Hurricanes Florence and Michael 
and the California wildfires, compared to 10.3 points in 2017, 
primarily  related  to  Hurricanes  Harvey,  Irma  and  Maria  and 
California wildfires. The balance of the change in the 2018 loss 
ratio resulted, in part, from changes in mix of business and the 
level of large attritional losses.

2017 versus 2016: The insurance segment’s current year loss 
ratio was 10.1 points higher in 2017 than in 2016. The 2017 
loss ratio included 10.3 points of current year catastrophic event 
activity, primarily related to Hurricanes Harvey, Irma and Maria 
and the California wildfires, compared to 2.2 points in 2016. 
The  2017  loss  ratio  also  reflected  changes  in  the  level  of 
attritional large losses and changes in the mix of business.

Prior Period Reserve Development.

The insurance segment’s net favorable development was $24.4 
million, or 1.1 points, for 2018, compared to $8.6 million, or

0.4 points, for 2017, and $33.1 million, or 1.6 points, for 2016. 
See  note  5,  “Reserve  for  Losses  and  Loss  Adjustment 
Expenses,” to our consolidated financial statements in Item 8 
for information about the insurance segment’s prior year reserve 
development.

Underwriting Expenses. 

2018  versus  2017:  The  insurance  segment’s  underwriting 
expense ratio was 32.4% in 2018, compared to 32.3% in 2017. 
The  comparison  of  the  underwriting  expense  ratios  reflects 
changes in the mix of business due to growth in lines of business 
with higher acquisition costs.

2017  versus  2016:  The  insurance  segment’s  underwriting 
expense ratio was 32.3% in 2017, compared to 31.6% in 2016

The  reinsurance  segment  consists  of  our  reinsurance 
underwriting  units  which  offer  specialty  product  lines  on  a 
worldwide basis. Product lines include: 

•  Casualty: provides coverage to ceding company clients on 
third party liability and workers’ compensation exposures from 
ceding company clients, primarily on a treaty basis. Exposures 
include,  among  others,  executive  assurance,  professional 
liability, workers’ compensation, excess and umbrella liability, 
excess motor and healthcare business.

•  Marine and aviation: provides coverage for energy, hull, 
cargo,  specie,  liability  and  transit,  and  aviation  business, 
including airline and general aviation risks. Business written 
may also include space business, which includes coverages for 
satellite assembly, launch and operation for commercial space 
programs.

•  Other  specialty:  provides  coverage  to  ceding  company 
clients for proportional motor and other lines, including surety, 
accident  and  health,  workers’  compensation  catastrophe, 
agriculture, trade credit and political risk. 

•  Property  catastrophe:  provides  protection  for  most 
catastrophic losses that are covered in the underlying policies 
written by reinsureds, including hurricane, earthquake, flood, 
tornado, hail and fire, and coverage for other perils on a case-
by-case  basis.  Property  catastrophe  reinsurance  provides 
coverage on an excess of loss basis when aggregate losses and 
loss  adjustment  expense  from  a  single  occurrence  or 
aggregation of losses from a covered peril exceed the retention 
specified in the contract.

•  Property  excluding  property  catastrophe:  provides 
coverage  for  both  personal  lines  and  commercial  property 
exposures  and  principally  covers  buildings,  structures, 
equipment  and  contents. The  primary  perils  in  this  business 
include fire, explosion, collapse, riot, vandalism, wind, tornado,

flood  and  earthquake.  Business  is  assumed  on  both  a 
proportional and excess of loss basis. In addition, facultative 
business  is  written  which  focuses  on  individual  commercial 
property risks on an excess of loss basis.

•  Other:  includes  life  reinsurance  business  on  both  a 
proportional  and  non-proportional  basis,  casualty  clash 
business  and,  in  limited  instances,  non-traditional  business 
which  is  intended  to  provide  insurers  with  risk  management 
solutions that complement traditional reinsurance.

2018 versus 2017: Gross premiums written by the reinsurance 
segment in 2018 were 16.6% higher than in 2017, while net 
premiums written were 16.9% higher than in 2017. The increase 
in net premiums written reflected growth in casualty lines and 
property lines, primarily due to new business and rate increases, 
and in other specialty, primarily due to new international motor 
contracts.  Net  premiums  written  in  2018  also  included 
reinstatement  premiums  of  $4.0  million,  primarily  for 
Hurricanes  Florence  and  Michael,  Typhoon  Jebi,  California 
wildfires and adjustments for other events, compared to $15.9 
million in 2017 for Hurricanes Harvey, Irma, Maria, as well as 
adjustments for other events.

2017 versus 2016: Gross premiums written by the reinsurance 
segment  in  2017  were  9.8%  higher  than  in  2016,  while  net 
premiums written were 11.4% higher than in 2016. Premiums 
written reflected growth in other specialty business, primarily 
in  international  motor  quota  share  contracts,  and  in  casualty 
business,  primarily  due  to  a  $45.4  million  retroactive 
reinsurance  contract  which  was  substantially  earned  in  the 
period and resulted in a corresponding increase to losses and 
loss  adjustment  expenses.  Net  premiums  written  in  2017 
included  reinstatement  premiums  of  $15.9  million  for 
Hurricanes  Harvey,  Irma  and  Maria.  Such  amounts  were 
partially offset by a reduction in property excluding property 
catastrophe business, primarily related to a targeted reduction 
in onshore energy writings.

Net premiums earned in 2018 were 10.4% higher than in 2017, 
reflecting changes in net premiums written over the previous 
five quarters, including the mix and type of business written. 
Net premiums earned in 2017 were 8.2% higher than in 2016. 

Other Underwriting Income (Loss).

Other underwriting loss in 2018 was $0.7 million, compared to 
other underwriting income of $11.3 million in 2017 and $36.4 
million in 2016. The 2016 period included $19.1 million related 
to  a  contract  which  was  commuted  during  the  2016  second 
quarter. This contract had been reflected as a deposit accounting 
liability (i.e., a contract that, in accordance with GAAP, does 
not pass risk transfer) prior to the commutation.

Current Year Loss Ratio.

2018 versus 2017: The reinsurance segment’s current year loss 
ratio was 4.1 points lower in 2018 than in 2017. The 2018 loss 
ratio included 10.1 points for current year catastrophic event 
activity, primarily related to Hurricanes Florence and Michael, 
Typhoon Jebi and the California wildfires, compared to 16.0 
points in 2017, primarily related to Hurricanes Harvey, Irma 
and  Maria  and  the  California  wildfires.  The  2018  loss  ratio 
includes the impact of a large attritional casualty loss arising 
from the California wildfires that increased the loss ratio by 1.7 
points. The balance of the change in the 2018 current year loss 
ratio resulted, in part, from the effects of market conditions and 
changes in the mix of business.

2017 versus 2016: The reinsurance segment’s current year loss 
ratio was 16.5 points higher in 2017 than in 2016. The 2017 
loss  ratio  included  16.0  points  for  current  year  catastrophic 
event activity, primarily related to Hurricanes Harvey, Irma and 
Maria and the California wildfires, compared to 4.1 points in 
2016. In addition, the loss ratio for 2017 reflects the impact of 
the retroactive reinsurance contract noted above (net premiums 
earned at a high loss ratio), which increased the current year 
loss ratio by 1.3 points. The balance of the change in the 2017 
current year loss ratio resulted, in part, from the effects of market 
conditions and changes in the mix of business.

Prior Period Reserve Development.

The  reinsurance  segment’s  net  favorable  development  was 
$138.5 million, or 11.0 points, for 2018, compared to $165.4 
million, or 14.5 points, for 2017, and $218.8 million, or 20.7 
points,  for  2016.  See  note  5,  “Reserve  for  Losses  and  Loss

statements  in  Item  8  for  information  about  the  reinsurance 
segment’s prior year reserve development.

Underwriting Expenses.

2018  versus  2017:  The  underwriting  expense  ratio  for  the 
reinsurance segment was 27.4% in 2018, compared to 32.2%
in 2017, reflecting lower operating expenses of $13.3 million 
due  to  lower  performance  based  compensation  costs,  a 
reduction of 1.1 points in the expense ratio. In addition, federal 
excise  taxes  decreased  by  $19.7  million,  a  reduction  of  1.6 
points in the expense ratio, due to the non-renewal of certain 
reinsurance agreements between our U.S. based insurance and 
reinsurance subsidiaries and Arch Re Bermuda on a cutoff basis 
as of January 1, 2018 and the impact of a loss portfolio transfer 
in 2017. The remainder of the change was due to changes in the 
mix and type of business.

2017  versus  2016:  The  underwriting  expense  ratio  for  the 
reinsurance segment was 32.2% in 2017, compared to 33.6%
in 2016. Due to intercompany loss portfolio transfers effective 
on  December  31,  2017  that  transferred  $1.36  billion  of  net 
retained  reserves  for  losses  and  allocated  loss  adjustment 
expenses between subsidiaries, the reinsurance segment’s 2017 
acquisition expense ratio reflected 1.2 points of federal excise 
taxes in connection with such activity.

Mortgage Segment

Our  mortgage  operations  include  U.S.  and  international 
mortgage  insurance  and  reinsurance  operations  as  well  as 
participation  in  GSE  credit  risk-sharing  transactions.  Our

2018 versus 2017: Gross premiums written by the mortgage 
segment in 2018 were 0.5% lower than in 2017. The reduction 
in gross premiums written primarily reflected a lower level of 
Australian  mortgage  reinsurance  business  partially  offset  by 
higher U.S. premiums due to insurance in force growth. Net 
premiums written for 2018 were 4.2% higher than in the 2017 
period and reflected lower ceded premiums on the quota share 
agreement with AIG that continues to run-off, partially offset 
by higher ceded premiums related to Bellemeade transactions 
in 2018. The 2017 period also reflected higher retrocessions of 
Australian mortgage reinsurance business. The persistency rate 
of the primary portfolio of mortgage loans of Arch MI U.S. was 
81.5%  at  December 31,  2018  compared 
to  81.8%  at 
December 31,  2017.  The  persistency  rate  represents  the 
percentage of mortgage insurance in force at the beginning of 
a 12-month period that remains in force at the end of such period.

2017 versus 2016: Gross premiums written by the mortgage 
segment in 2017 were 173.8% higher than in 2016,  while net 
premiums  written  increased  183.9%,  primarily  reflecting 
growth in insurance in force due to the acquisition of UGC,

Arch MI U.S. generated $69.5 billion of new insurance written 
(“NIW”) during 2018 compared to $62.0 billion during 2017. 
NIW represents the original principal balance of all loans that 
received coverage during the period.

primarily due to growth in insurance in force for Arch MI U.S. 
Growth from 2016 to 2017 primarily reflected the impact of the 
acquisition of UGC, which occurred as of December 31, 2016. 

Other Underwriting Income.

Other underwriting income, which is primarily related to GSE 
risk-sharing  transactions  receiving  derivative  accounting 
treatment,  was  $13.0  million  for  2018,  compared  to  $15.7

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  insurance 
products  if  the  amount  of  expected  future  losses  and 
maintenance costs exceeds expected future premiums, existing 

reserves  and  the  anticipated  investment  income  for  such 
product. We assess the need for a premium deficiency reserve 
on a quarterly basis and perform a full analysis annually. No 
such reserve was established during 2018, 2017 or 2016.

Current Year Loss Ratio.

2018 versus 2017: The mortgage segment’s current year loss 
ratio  was  5.7  points  lower  in  2018  compared  to  2017.  The 
current year loss ratio for 2018 reflects the current favorable 
macroeconomic  environment  as  the  percentage  of  loans  in 
default on first lien business decreased from 2.23% at December 
31, 2017 to 1.60% at December 31, 2018. In addition, the loss 
ratio  for  2017  was  slightly  impacted  by  delinquencies 
emanating from new notices from areas impacted by the 2017 
third quarter hurricanes that subsequently cured during 2018.

2017 versus 2016: The mortgage segment’s current year loss 
ratio  was  4.2  points  higher  in  2017  compared  to  2016.  The 
current year loss ratio for 2017 reflects changes in the mix of 
business due to the UGC acquisition when compared to 2016, 
and  the  minor  impact  of  delinquencies  emanating  from  new 
notices  from  areas  impacted  by  the  2017  third  quarter 
hurricanes.

We insure mortgages for homes in areas that have been impacted 
by  catastrophic  events,  including  2018  events  such  as 
Hurricanes Florence and Michael and the California wildfires, 
and  2017  events  such  as  Hurricanes  Harvey  and  Irma. 
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 $107.6 
million, or 9.1 points, for 2018, compared to $95.0 million, or 
9.0 points, for 2017, and $21.2 million, or 7.4 points, for 2016. 
The 2017 increase in net favorable development was primarily 
on the acquired UGC reserves. 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.

2018  versus  2017:  The  underwriting  expense  ratio  for  the 
mortgage segment was 22.0% for 2018, compared to 23.3% for 
2017, reflecting the increase in net premiums earned combined 

ARCH CAPITAL

67

2018 FORM 10-K

with a $3.9 million decrease in other operating expenses due to 
expense  savings  from  integration  efforts.  This  decrease  was 
partially offset by a higher level of acquisition expenses, due 
to higher NIW.

2017  versus  2016:  The  underwriting  expense  ratio  for  the 
mortgage segment was 23.3% for 2017, compared to 41.3% for 
2016. The decrease in the underwriting expense ratio primarily 
reflects the higher level of net premiums earned from the impact 
of  the UGC acquisition. 

Corporate (Non-Underwriting) Segment

The corporate (non-underwriting) segment results include net 
investment income, other income (loss), corporate expenses, 
transaction costs and other, amortization of intangible assets, 
interest expense, items related to our non-cumulative preferred 
shares,  net  realized  gains  or  losses,  net  impairment  losses 
included in earnings, equity in net income or loss of investments 
accounted for using the equity method, net foreign exchange 
gains or losses and income taxes. Such amounts exclude the 
results of the ‘other’ segment.

Net Investment Income. 

The components of net investment income were derived from 
the following sources:

Fixed maturities
Equity securities
Short-term investments

(1)   Amounts include dividends and other distributions on investment funds, 
term loan investments, funds held balances, cash balances and other.
Investment  expenses  were  approximately  0.36%  of  average  invested 
assets for 2018, compared to 0.30% for 2017 and 0.34% for 2016.

(2) 

The  pre-tax  investment  income  yield  was  2.36%  for  2018, 
compared to 2.06% for 2017 and 1.92% for 2016. The higher 
level of net investment income for 2018 compared to 2017 and 
2016 reflected an increase in the embedded book yield on fixed 
income  securities,  partially  offset  by  a  higher  level  of 
expenses.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.

necessary to support our worldwide insurance and reinsurance 
operations  and  costs  associated  with  operating  as  a  publicly 
traded company. The lower level of corporate expenses in 2018
compared  to  2017  and  2016  was  primarily  due  to  lower 
incentive compensation costs.

Transaction Costs and Other.

Transaction  costs  and  other  were  $11.4  million  for  2018, 
compared to $22.2 million for 2017 and $41.7 million for 2016. 
Amounts for 2018 were primarily attributable to the write off 
of intangible assets related to insurance licenses for a subsidiary 
of UGC which was merged with another subsidiary. For 2017, 
transaction costs and other primarily related to severance and 
severance  related  costs  related  to  the  UGC  acquisition.  For 
2016, transaction costs and other included $32.3 million of non-
recurring costs such as advisory, financing and legal related to 
the UGC acquisition.

Amortization of Intangible Assets.

Amortization of intangible assets for 2018 was $105.7 million, 
compared  to  $125.8  million  for  2017  and  $19.3  million  for 
2016.  Amounts  in  2018  and  2017  primarily  related  to 
amortization of finite-lived intangible assets related to the UGC 
acquisition.

Interest Expense. 

Interest  expense  was  $101.0  million  for  2018,  compared  to 
$103.6 million for 2017 and $53.5 million for 2016. Interest 
expense  reflects  amounts  related  to  our  outstanding  senior 
notes,  revolving  credit  agreement  borrowings  and  other. We 
issued  $950.0  million  of  senior  notes  in  December  2016  in 
connection  with  the  UGC  acquisition  and  borrowed  $400.0 
million on our revolving credit agreement, resulting in higher 
borrowing costs in 2017 when compared to 2016. We repaid 
$375  million  and  $125  million  of  our  revolving  credit 
agreement  borrowings  during  2018  and  2017,  respectively, 
resulting in lower borrowing costs for 2018 than in 2017.

Loss on Redemption of Preferred Shares.

In September 2017, we redeemed $230 million of 6.75% Series 
C preferred shares and, in accordance with GAAP, recorded a 
loss of $6.7 million to remove original issuance costs related 
to  the  redeemed  shares  from  additional  paid-in  capital.  In 
January  2018,  we  redeemed  the  remaining  $92.3  million  of 
6.75%  Series  C  preferred  shares  outstanding  and  recorded  a 
loss of $2.7 million. Such adjustments had no impact on total 
shareholders’ equity or cash flows.

Corporate Expenses. 

Net Realized Gains (Losses). 

Corporate expenses were $58.6 million for 2018, compared to 
$61.6  million  for  2017  and  $49.4  million  for  2016.  Such 
amounts  primarily  represent  certain  holding  company  costs 

We  recorded  net  realized  loss  of  $284.4  million  for  2018, 
compared to net realized gains of $148.8 million for 2017 and 
net  realized  gains  of  $69.6  million  for  2016.  Currently,  our 

ARCH CAPITAL

2018 FORM 10-K

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 and losses as the portfolio is adjusted and 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 
includes realized and unrealized contract gains and losses on 
our derivative instruments, changes in the fair value of assets 
and liabilities accounted for using the fair value option along 
with  re-measurement  of  contingent  consideration  liability 
amounts. 

Net Impairment Losses Recognized in Earnings. 

For  2018,  we  recorded  $2.8  million  of  credit  related 
impairments in earnings, compared to $7.1 million in 2017 and 
$30.4 million in 2016. The impairment losses recorded in 2018 
were  primarily  related  to  foreign  currency.  The  impairment 
losses  recorded  in  2017  were  primarily  related  to  foreign 
currency and the liquidation of one portfolio, while the 2016 
period included reductions on two asset backed securities based 
on  information  received  from  external  investment  managers 
and  a  review  of  cash  flow  projections  in  order  to  determine 
expected recovery values. See note 8, “Investment Information
—Other-Than-Temporary  Impairments,”  to  our  consolidated 
financial statements in Item 8 for additional information.

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

We recorded $45.6 million of equity in net income related to 
investments accounted for using the equity method for 2018, 
compared  to  $142.3  million  for  2017  and  $48.5  million  for 
2016.  The  2017  results  reflected  strong  returns  on  funds 
invested  in  global  equities  and  other  strategies.  Investments 
accounted for using the equity method totaled $1.49 billion at 
December 31, 2018, compared to $1.04 billion at December 31, 
2017. See note 8, “Investments—Equity in Net Income (Loss) 
of Investments Accounted For Using the Equity Method,” to 
our consolidated financial statements in Item 8 for additional 
information.

Net Foreign Exchange Gains or Losses. 

Net  foreign  exchange  gains  for  2018  were  $58.7  million, 
compared to net foreign exchange losses for 2017 of $113.3 
million  and  net  foreign  exchange  gains  for  2016  of  $31.4 
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  13.1%  for  2018,  compared  to  an 
expense of 17.1% for 2017 and an expense of 4.3% for 2016. 
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.  Income  tax 
expense for 2017 included a net $8.1 million charge due to the 
revaluation of our net U.S. deferred tax asset resulting from the 
reduction in the U.S. corporate income tax rate from 35% to 
21% effective January 1, 2018.

See  note  14,  “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 2018, 
2017 and 2016.

Other Segment 

The  ‘other’  segment  includes  the  results  of  Watford  Re. 
Pursuant to generally accepted accounting principles, Watford 
Re is considered a variable interest entity and we concluded 
that we are the primary beneficiary of Watford Re. As such, we 
consolidate  the  results  of  Watford  Re  in  our  consolidated 
financial statements, although we only own approximately 11% 
of Watford Re’s common equity. See note 11, “Variable Interest 
Entity  and  Noncontrolling  Interests,”  and  note  4,  “Segment 
Information,” to our consolidated financial statements in Item 
8 for additional information.

CRITICAL  ACCOUNTING  POLICIES,  ESTIMATES 
AND  RECENT  ACCOUNTING  PRONOUNCEMENTS

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 recognition, insurance and other reserves, reinsurance 
recoverables,  allowance  for  doubtful  accounts,  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.  Estimates  and  judgments  for  a 
relatively  new  insurance  and  reinsurance  company,  like  our 
company, are even more difficult to make than those made in 
a  mature  company  since  relatively 
limited  historical 
information  has  been  reported  to  us  through  December 31, 
2018. Actual results will differ from these estimates and such 
differences  may  be  material.  We  believe  that  the  following 

ARCH CAPITAL

69

2018 FORM 10-K

critical accounting policies affect significant estimates used in 
the preparation of our consolidated financial statements.

Reserves for Losses and Loss Adjustment Expenses

We are required by applicable insurance laws and regulations 
and GAAP to establish reserves for losses and loss adjustment 
expenses,  or  Loss  Reserves,  that  arise  from  the  business  we 
underwrite. Loss Reserves for our insurance, reinsurance and 
mortgage operations are balance sheet liabilities representing 
estimates  of  future  amounts  required  to  pay  losses  and  loss 
adjustment expenses for insured or reinsured events which have 
occurred at or before the balance sheet date. Loss Reserves do 
not reflect contingency reserve allowances to account for future 
loss  occurrences.  Losses  arising  from  future  events  will  be 
estimated and recognized at the time the losses are incurred and 
could be substantial.

See  note  6,  “Short  Duration  Contracts,”  to  our  consolidated 
financial statements in Item 8 for additional information on our 
reserving process.

At  December 31,  2018  and  2017,  our  Loss  Reserves,  net  of 
unpaid losses and loss adjustment expenses recoverable, by type 
and by operating segment were as follows:

Potential Variability in Loss Reserves

The  tables  below  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, 2018 by underwriting 
segment (excluding the ‘other’ segment). The scenarios shown 
in the tables summarize the effect of (i) changes to the expected 
loss  ratio  selections  used  at  December 31,  2018,  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, 2018, 
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 

ARCH CAPITAL

70

2018 FORM 10-K

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, 2018 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,  2018  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 27% of the 
unpaid principal balance at December 31, 2018), we estimated 
that our loss reserves would change by approximately $17.0 
million at December 31, 2018. For every one percentage point 
change  in  our  primary  net  default  to  claim  rate  (which  we

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,  2018,  our  recorded  Loss  Reserves  by 
underwriting segment, net of unpaid losses and 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  $1.40  billion,  or  $3.38  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 $1.31 billion, or 
$3.17 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. We do not have 
significant exposure to pre-2002 liabilities, such as asbestos-
related illnesses and other long-tail liabilities. It is difficult to 
provide  meaningful  trend  information  for  certain  liability/
casualty coverages for which the claim-tail may be especially 
long, as claims are often reported and ultimately paid or settled 
years, or even decades, after the related loss events occur. Any 

estimates and assumptions made as part of the reserving process 
could prove to be inaccurate due to several factors, including 
the fact that relatively limited historical information has been 
reported to us through December 31, 2018.

Ceded Reinsurance

In the normal course of business, our insurance and mortgage 
insurance operations cede a portion of their premium on a quota 
share  or  excess  of  loss  basis  through  treaty  or  facultative 
reinsurance agreements. Our reinsurance operations also obtain 

ARCH CAPITAL

by 

our 

reinsurance 

reinsurance whereby another reinsurer contractually agrees to 
indemnify  it  for  all  or  a  portion  of  the  reinsurance  risks 
underwritten 
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.  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—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.”

Effective July 1, 2018, our insurance operations had in effect a 
reinsurance  program  which  provided  coverage  for  certain 
property-catastrophe  related  losses  equal  to  $275  million  in 
excess of a $75 million retention per occurrence. Such amounts 
compare to $200 million in excess of a $150 million retention 
per occurrence prior to July 1, 2018.

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  23.2%  of  gross  premiums  written  for  2018, 
compared to 22.1% for 2017 and 22.5% for 2016. 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 provide 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. If our analysis indicates 
that  there  is  significant  uncertainty  regarding  our  ability  to 

collect amounts due from reinsurers, managing general agents, 
brokers and other clients, we will record a provision for doubtful 
accounts. See “Risk Factors—Risks Relating to Our Company
—We  are  exposed  to  credit  risk  in  certain  of  our  business 
operations”  and  “Financial  Condition,  Liquidity  and  Capital 
Resources—Financial Condition—Premiums Receivable and 
Reinsurance Recoverables” for further details.

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 
insurance 
include  estimates 
operations’  programs,  specialty  lines,  collateral  protection 
business  and  for  participation  in  involuntary  pools.  Such 
premium  estimates  are  derived  from  multiple  sources  which 
include  the  historical  experience  of  the  underlying  business, 
similar business and available industry information. Unearned 
premium reserves represent the portion of premiums written 
that relates to the unexpired terms of in-force insurance policies.

in  our 

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

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.

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 
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 
reflects 
management’s judgment, as described above in “—Reserves 
for Losses and Loss Adjustment Expenses.”

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, 
management believes that the premium estimates included in 
premiums  receivable  will  be  collectible  and,  therefore,  no 
provision  for  doubtful  accounts  has  been  recorded  on  the 
premium estimates at December 31, 2018.

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  inception  of  the  reinsurance 
transaction, with a corresponding charge or credit to income.

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 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. 

Unearned premiums represent the portion of premiums written

trigger a lender permitted or legally required cancellation, or

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.

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.  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 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 interest 
income. Evaluating the expected profitability of our existing

Fair Value Measurements

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). 

We determine the existence of an active market based on our 
judgment as to whether transactions for the financial instrument 
occur in such market with sufficient frequency and volume to 
provide reliable pricing information. The independent pricing 
sources obtain market quotations and actual transaction prices 
for securities that have quoted prices in active markets. We use 
quoted values and other data provided by nationally recognized 
independent  pricing  sources  as  inputs  into  our  process  for 
determining fair values of our fixed maturity investments. To 
validate the techniques or models used by pricing sources, our 
review  process  includes,  but  is  not  limited  to:  quantitative 
analysis (e.g., comparing the quarterly return for each managed 
portfolio to their target benchmark, with significant differences 
identified and investigated); a review of the average number of 
prices obtained in the pricing process and the range of resulting 
fair  values;  initial  and  ongoing  evaluation  of  methodologies 
used by outside parties to calculate fair value; comparing the 
fair value estimates to our knowledge of the current market; a 
comparison of the pricing services’ fair values to other pricing 
services’ fair values for the same investments; and back-testing, 
which includes randomly selecting purchased or sold securities 
and comparing the executed prices to the fair value estimates 
from the pricing service. Where multiple quotes or prices were 
obtained, 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

other  factors  (e.g.,  interest  rates,  market  conditions,  etc.)  is 
recorded  as  a  component  of  other  comprehensive  income  or 
loss. The amount of the credit loss of an impaired debt security 
is the difference between the amortized cost and the greater of 
(i) the present value of expected future cash flows and (ii) the 
fair value of the security. In instances where no credit loss exists 
but it is more likely than not that we will have to sell the debt 
security  prior  to  the  anticipated  recovery,  the  decline  in  fair 
value  below  amortized  cost  is  recognized  as  an  OTTI  in 
earnings. In periods after the recognition of an OTTI on debt 
securities, we account for such securities as if they had been 
purchased on the measurement date of the OTTI at an amortized 
cost basis equal to the previous amortized cost basis less the 
OTTI  recognized  in  earnings.  For  debt  securities  for  which 
OTTI were recognized in earnings, the difference between the 
new  amortized  cost  basis  and  the  cash  flows  expected  to  be 
collected  will  be  accreted  or  amortized  into  net  investment 
income.

For  2018,  we  recorded  $2.8  million  of  credit  related 
impairments in earnings, compared to $7.1 million in 2017 and 
$30.4 million in 2016. See note 8, “Investment Information—
Other-Than-Temporary  Impairments,”  to  our  consolidated 
financial statements in Item 8 for additional information.

Reclassifications

We  have  reclassified  the  presentation  of  certain  prior  year 
information  to  conform  to  the  current  presentation.  Such 
reclassifications had no effect on our net income, shareholders’ 
equity or cash flows.

Recent Accounting Pronouncements

See  note  3(q),  “Significant  Accounting  Policies—Recent 
Accounting  Pronouncements,”  to  our  consolidated  financial 
statements  in  Item  8  for  disclosures  concerning  recent 
accounting pronouncements.

hierarchy will be used from 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, we will challenge any prices for a 
security  or  portfolio  which  are  considered  not  to  be 
representative of fair value.

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.  In  addition, 
pricing  vendors  use  model  processes,  such  as  an  Option 
Adjusted  Spread  model,  to  develop  prepayment  and  interest 
rate scenarios. The Option Adjusted Spread model is commonly 
used  to  estimate  fair  value  for  securities  such  as  mortgage 
backed and asset backed securities. In certain circumstances, 
when fair values are unavailable from these independent pricing 
sources, quotes are obtained directly from broker-dealers who 
are active in the corresponding markets. Such quotes are subject 
to the validation procedures noted above. 

We review our securities measured at fair value and discuss the 
proper  classification  of  such  investments  with  investment 
advisors  and  others.  See  note  9,  “Fair  Value,”  to  our 
consolidated financial statements in Item 8 for a summary of 
our  financial  assets  and  liabilities  measured  at  fair  value  at 
December 31, 2018 by valuation hierarchy.

Other-Than-Temporary Impairments 

On a quarterly basis, we perform reviews of our investments to 
determine whether declines in fair value below the cost basis 
are  considered  other-than-temporary  in  accordance  with 
applicable accounting guidance regarding the recognition and 
presentation  of  other-than-temporary  impairments  (“OTTI”). 
The process of determining whether a security is other-than-
temporarily impaired requires judgment and involves analyzing 
many factors. These factors include: an analysis of the liquidity, 
business prospects and overall financial condition of the issuer; 
the time period in which there was a significant decline in value; 
the significance of the decline; and the analysis of specific credit 
events.

For debt securities, we separate an OTTI into two components 
when there are credit related losses associated with the impaired 
debt security for which we assert that we do not have the intent 
to sell the security, and it is more likely than not that we will 
not be required to sell the security before recovery of its cost 
basis.  The  amount  of  the  OTTI  related  to  a  credit  loss  is 
recognized in earnings, and the amount of the OTTI related to

Investable Assets

At  December 31,  2018,  total  investable  assets  held  by Arch 
were $19.57 billion, excluding the $2.76 billion included in the 
‘other’ segment (i.e., attributable to Watford Re).

Investable Assets Held by Arch 

The Finance, Investment and Risk Committee (“FIR”) of our 
board of directors 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 strategy in conjunction with the FIR.

Reinsurance Recoverables

At  December 31,  2018  and  2017,  approximately  63.0%  and 
69.9% of reinsurance recoverables on paid and unpaid losses 
(not including ceded unearned premiums) of $2.92 billion and 
$2.54 billion, respectively, were due from carriers which had 
an A.M. Best rating of “A-” or better while 37.0% and 30.1%, 
respectively,  were  from  companies  not  rated.  For  items  not 
rated,  over  90%  of  such  amount  was  collateralized  through 
reinsurance trusts or letters of credit at December 31, 2018 and 
2017. The largest reinsurance recoverables from any one carrier 
was  approximately  2.7%  and  2.2%,  respectively,  of  total 
shareholders’ equity available to Arch at December 31, 2018 
and 2017.

Reserves for Losses and Loss Adjustment Expenses

We  establish  reserves  for  losses  and  LAE  (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,  which  is 
exacerbated by the fact that we have relatively limited historical 
experience  upon  which  to  base  such  estimates.  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  the  reserve  estimates  reflected  in  our 
financial  statements.  See  “Management’s  Discussion  and 
Analysis of Financial Condition and Results of Operations—
Critical Accounting Policies, Estimates and Recent Accounting 
Pronouncements—Reserves for Losses and Loss Adjustment 
Expenses” and “Business—Reserves” for further details.

LIQUIDITY

This section does not include information specific to Watford 
Re. We do not guarantee or provide credit support for Watford 
Re, and our financial exposure to Watford Re is limited to our 
investment in Watford Re’s common and preferred shares and 
counterparty credit risk (mitigated by collateral) arising from 
reinsurance transactions with Watford Re.

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  2018, Arch  Capital  received  dividends  of  $398.7  million 
from  Arch  Re  Bermuda,  our  Bermuda-based  reinsurer  and 
insurer. In 2018, Arch-U.S. received $25.0 million of dividends 
from Arch  Re  U.S.,  our  U.S.  licensed  reinsurer,  and  $525.0 
million of dividends from Arch U.S. MI Holdings. Arch U.S. 
MI Holdings received aggregate dividends and return of capital 
from  subsidiaries  of  $971.1  million  in  2018.  Arch  U.S.  MI 

Holdings used such proceeds to pay down $375.0 million of its 
revolving credit agreement borrowings and pay dividends to 
Arch-U.S.

Our insurance and reinsurance operations provide liquidity in 
that premiums are received 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  future.  Sources  of  liquidity 
include cash flows from operations, financing arrangements or 
routine sales of investments.

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

We expect that our liquidity needs, including our anticipated 
insurance  obligations  and  operating  and  capital  expenditure 
needs, for the next twelve months, at a minimum, 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.

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 
23,  “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 levels of 
our  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,  2018  and  2017,  such  amounts  approximated 
$6.76 billion and $6.01 billion, respectively, excluding amounts 
related to the ‘other’ segment.

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 ventures such as Watford Re 
and  others  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  $1.77  billion  at 
December 31,  2018  and  are  callable  by  our  investment 
managers.  The 
investment 
commitments is uncertain and may require us to access cash on 
short notice.

collateral  related  to  securities  lending  and  a  $125  million 
repayment  of  borrowing  on  our  revolving  credit  agreement. 
Cash provided by financing activities for 2016 reflected various 
capital raising activity, such as the issuance of $950.0 million 
of senior notes and $450.0 million of preferred shares combined 
with $400.0 million of borrowings under our revolving credit 
facility in order to fund some of the cash consideration portion 
of the UGC acquisition. 

CAPITAL RESOURCES

This section does not include information specific to Watford 
Re. We do not guarantee or provide credit support for Watford 
Re, and our financial exposure to Watford Re is limited to our 
investment in Watford Re’s common and preferred shares and 
counterparty credit risk (mitigated by collateral) arising from 
reinsurance transactions with Watford Re.

Investments 

The following table provides an analysis of our capital structure:

At  December 31,  2018,  our  investable  assets  were  $19.57 
billion, excluding the $2.76 billion of investable assets related 
to the ‘other’ segment. The primary goals of our asset liability 
management  process  are  to  satisfy  the  insurance  liabilities, 
manage  the  interest  rate  risk  embedded  in  those  insurance 
liabilities and maintain sufficient liquidity to cover fluctuations 
in  projected  liability  cash  flows,  including  debt  service 
obligations.  Generally,  the  expected  principal  and  interest 
payments produced by our fixed income portfolio adequately 
fund the estimated runoff of our insurance reserves. Although 
this  is  not  an  exact  cash  flow  match  in  each  period,  the 
substantial degree by which the fair value of the fixed income 
portfolio exceeds the expected present value of the net insurance 
liabilities, as well as the positive cash flow from newly sold 
policies  and  the  large  amount  of  high  quality  liquid  bonds, 
provide assurance of our ability to fund the payment of claims 
and  to  service  our  outstanding  debt  without  having  to  sell 
securities at distressed prices or access credit facilities. 

Changes  in  general  economic  conditions,  including  new  or 
continued  sovereign  debt  concerns  in  Eurozone  countries  or 
downgrades of U.S. securities by credit rating agencies, could 
have  a  material  adverse  effect  on  financial  markets  and 
economic conditions in the U.S. and throughout the world. In 
turn, this could have a material adverse effect on our business, 
financial condition and results of operations and, in particular, 
this  could  have  a  material  adverse  effect  on  the  value  and 
liquidity  of  securities  in  our  investment  portfolio.  Our 
investment portfolio as of December 31, 2018 included $415.6 
million  of  securities  issued  and/or  guaranteed  by  Eurozone 
governments at fair value, $3.60 billion of obligations of the 
U.S.  government  and  government  agencies  at  fair  value  and 
$1.01 billion of municipal bonds at fair value. Please refer to 
Item 1A “Risk Factors” for a discussion of other risks relating 
to our business and investment portfolio.

Arch Capital and Arch-U.S. are each holding companies and, 
accordingly, they conduct substantially all of their operations 
through their operating subsidiaries. Arch Capital Finance LLC 
(“Arch Finance”) is a wholly owned subsidiary of Arch U.S. 
MI Holdings Inc., a U.S. holding company. As a result, Arch 
Capital, Arch-U.S.  and Arch  Finance's  cash  flows  and  their 
ability to service their debt depends upon the earnings of their 
operating  subsidiaries  and  on  their  ability  to  distribute  the 
earnings,  loans  or  other  payments  from  such  subsidiaries  to 
Arch Capital, Arch-U.S. and Arch Finance, respectively.

agreement  borrowings.  For  additional  information  on  our 
preferred shares, see note 19, “Shareholders’ Equity,” to our 
consolidated financial statements in Item 8.

During 2018, 2017 and 2016, we made interest payments of 
$100.1 million, $103.7 million and $50.4 million, respectively, 
related to our senior notes and other financing arrangements.

In November 2017, Arch Capital, Arch-U.S. and Arch Finance 
filed a universal shelf registration statement with the SEC. This 
registration statement allows for the possible future offer and 
sale by us of various types of securities, including unsecured 
debt securities, preference shares, common shares, warrants, 
share purchase contracts and units and depositary shares. The 
shelf registration statement enables us to efficiently access the 
public debt and/or equity capital markets in order to meet our 
future capital needs. The shelf registration statement also allows 
selling shareholders to resell common shares that they own in 
one or more offerings from time to time. We will not receive 
any  proceeds  from  any  shares  offered  by  the  selling 
shareholders.

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.

In addition, Arch MI U.S. is required to maintain compliance 
with the GSEs requirements, known as the Private Mortgage 
Insurer Eligibility Requirements or “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, 2018 with a PMIER sufficiency ratio of 141%, 
compared to 129% at December 31, 2017.

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 our board of directors 
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 of directors 
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  U.S.-based 
insurance,  reinsurance  and  mortgage  insurance  subsidiaries 
have entered into separate reinsurance arrangements with Arch 
Re  Bermuda  covering  individual  lines  of  business.  The 
reinsurance  agreements  between  our  U.S.-based  property 
casualty insurance and reinsurance subsidiaries and Arch Re 
Bermuda were canceled on a cutoff basis as of January 1, 2018. 
As  a  result,  the  level  of  subject  business  ceded  to Arch  Re 
Bermuda was substantially lower in 2018 than in prior periods.

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 
or other financial support 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 

The  board  of  directors  of  Arch  Capital  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,  2018,  Arch  Capital  has 
repurchased approximately 386.2 million common shares for 
an aggregate purchase price of $3.97 billion. At December 31, 
2018, approximately $163.7 million 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, 2019. 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. 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)  Pursuant to our 2014 acquisition of the CMG Entities, we are required to make remaining contingent consideration payments as re-calculated over an earn-

out period. For purposes of this table, the maximum exposure has been shown using an estimated payout pattern.

(5)  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.

(6)  As part of our securities lending program, we loan securities to third parties and receive collateral in the form of cash or securities. Such collateral is due 

back to the third parties at the close of the securities lending transactions, a majority of which is overnight and continuous by nature.

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 October 26, 2016, Arch Capital and certain of its subsidiaries 
entered  into  an  $850.0  million  five-year  credit  facility  (the 
“Credit  Facility”)  with  a  syndication  of  lenders.  The  Credit 
Facility consists of a $350.0 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. Subject to the receipt of commitments, the Secured 
Facility  may  be  increased  by  up  to  an  aggregate  of  $350.0 
million,  and  the  Unsecured  Facility  may  be  increased  to  an 
amount not to exceed $750.0 million. 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 LIBOR or an alternative base rate at the 
option of Arch Capital. Secured letters of credit are available 
for  issuance  on  behalf  of  Arch  Capital  insurance  and 
reinsurance subsidiaries. The Credit Facility is structured such

that each party that requests a letter of credit or borrowing does 
so only for itself and for only its own obligations.

have assigned financial strength ratings to one or more of Arch 
Capital’s subsidiaries. 

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, 2018.

Commitments under the Credit Facility will expire on October 
26, 2021, and all loans then outstanding must be repaid. Letters 
of credit issued under the Unsecured Facility will not have an 
expiration date later than October 26, 2022.

Under the $350.0 million secured letter of credit facility, Arch 
Capital’s  subsidiaries  had  $174.8  million  of  letters  of  credit 
outstanding  and  remaining  capacity  of  $175.2  million  at 
December 31,  2018.  In  addition,  certain  of  Arch  Capital’s 
subsidiaries had outstanding letters of credit of $167.5 million, 
which  were  issued  in  the  normal  course  of  business.  When 
issued, these letters of credit are secured by a portion of the 
investment  portfolio. At  December 31,  2018,  these  letters  of 
credit were secured by investments with a fair value of $362.0 
million.

The  Company’s  outstanding  revolving  credit  agreement 
borrowings were as follows:

RATINGS

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 
party internationally recognized statistical rating 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 
insurance or 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 

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 Internet site (www.ir.archcapgroup.com, under 
Credit Ratings) contains information about our ratings, but such 
information on our website is not incorporated by reference into 
this report. 

CATASTROPHIC EVENTS AND SEVERE ECONOMIC 
EVENTS 

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

We  have  substantial  exposure  to  unexpected,  large  losses 
resulting from future man-made catastrophic events, such as 
acts of war, acts of terrorism and political instability. These risks 
are inherently unpredictable. It is difficult to predict the timing 
of such events with statistical certainty or estimate the amount 
of loss any given occurrence will generate. It is not possible to 

ARCH CAPITAL

88

2018 FORM 10-K

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. 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, irrespective of the clarity 
and inclusiveness of policy language, there can be no assurance 
that a court or arbitration panel will limit enforceability of policy 
language or otherwise issue a ruling adverse to us.

We seek to limit our loss exposure by writing a number of our 
reinsurance contracts on an excess of loss basis, adhering to 
maximum  limitations  on  reinsurance  written  in  defined 
geographical zones, limiting program size for each client and 
prudent underwriting of each program written. In the case of 
proportional treaties, we may seek per occurrence limitations 
or loss ratio caps to limit the impact of losses from any one or 
series of events. In our insurance operations, we seek to limit 
our exposure through the purchase of reinsurance. We cannot 
be  certain  that  any  of  these  loss  limitation  methods  will  be 
effective. We also seek to limit our loss exposure by geographic 
diversification. Geographic zone limitations involve significant 
underwriting judgments, including the determination of the area 
of the zones and the inclusion of a particular policy within a 
particular zone's limits. There can 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 total 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, 2019, 
our modeled peak zone catastrophe exposure is a windstorm 
affecting the Northeastern U.S., with a net probable maximum 
pre-tax loss of $374 million, followed by windstorms affecting 
Florida Tri-County and the Gulf of Mexico with net probable 
maximum  pre-tax  losses  of  $330  million  and  $299  million, 
respectively.  Our  exposures  to  other  perils,  such  as  U.S. 
earthquake  and  international  events,  were  less  than  the 
exposures arising from U.S. windstorms and hurricanes in both 
periods.  As  of  January  1,  2019,  our  modeled  peak  zone 
earthquake  exposure 
(San  Francisco  area  earthquake) 
represented approximately 77% of our peak zone catastrophe 
exposure, and our modeled peak zone international exposure 
(Japan earthquake) was substantially less than both our peak 
zone windstorm and earthquake exposures.

We also have significant exposure to losses due to mortgage 
defaults resulting from severe economic events in the future. 
For our U.S. mortgage insurance business, we have developed 
a  proprietary  risk  model  (“Realistic  Disaster  Scenario”  or 
“RDS”)  that  simulates  the  maximum  loss  resulting  from  a 
severe economic downturn impacting the housing market. The 
RDS models the collective impact of adverse conditions for key 
economic indicators, the most significant of which is a decline 
in home prices. The RDS model projects paths of future home 
prices, unemployment rates, income levels and interest rates 
and assumes correlation across states and geographic regions.  
The resulting future performance of our in-force portfolio is 
then estimated under the economic stress scenario, reflecting 
loan and borrower information. 

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  (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,  2019,  our 
modeled RDS loss was less than 12% 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 after income tax. 
Catastrophe loss estimates are reflective of the zone indicated 

ARCH CAPITAL

89

2018 FORM 10-K

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 total shareholders' 
equity  or  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
—Risk  Relating  to  Our  Industry.”  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 “—Critical Accounting Policies, 
Estimates  and  Recent  Accounting  Pronouncements—Ceded 
Reinsurance” for a discussion of our catastrophe reinsurance 
programs.

OFF-BALANCE SHEET ARRANGEMENTS

interest  entities 

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,  2018,  our 
estimated off-balance sheet maximum exposure to loss from 
such entities was $11.2 million. See note 11, “Variable Interest 
Entity  and  Noncontrolling  Interests,”  to  our  consolidated 
financial statements in Item 8 for additional information.

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, 2018. 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, 2018
presents  hypothetical  losses  in  cash  flows,  earnings  and  fair 
values of market sensitive instruments which were held by us 
on December 31, 2018 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.

We have not included Watford Re in the following analyses as 
we do not guarantee or provide credit support for Watford Re, 
and  our  financial  exposure  to  Watford  Re  is  limited  to  its 
investment in Watford Re’s common and preferred shares and 
counterparty credit risk (mitigated by collateral) arising from 
the reinsurance transactions.

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  market  value  of  our  fixed 
maturities,  fixed  maturities  pledged  under  securities  lending 
agreements,  short-term  investments  and  certain  of  our  other 
investments  which  invest  in  fixed  income  securities  and  the 
corresponding change in unrealized appreciation. As interest 
rates  rise,  the  market  value  of  our  interest  rate  sensitive 
securities falls, and the converse is also true. Based on historical 
observations, there is a low probability that all 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,

In addition, we consider the effect of credit spread movements 
on the market value of our fixed maturities, fixed maturities 
pledged  under  securities  lending  agreements,  short-term 
investments  and  certain  of  our  other  investments  and 
investments accounted for using the equity method which invest 
in  fixed  income  securities  and  the  corresponding  change  in

at-Risk  (“VaR”).  VaR  attempts  to  take  into  account  a  broad 
cross-section  of  risks  facing  a  portfolio  by  utilizing  relevant 
securities  volatility  data  skewed  towards  the  most  recent 
months and quarters. VaR measures the amount of a portfolio 
at risk for outcomes 1.65 standard deviations from the mean 

based on normal market conditions over a one year time horizon 
and is expressed as a percentage of the portfolio’s initial value. 
In other words, 95% of the time, should the risks taken into 
account  in  the  VaR  model  perform  per  their  historical 
tendencies,  the  portfolio’s  loss  in  any  one  year  period  is 
expected to be less than or equal to the calculated VaR, stated 
as a percentage of the measured portfolio’s initial value. As of 
December 31, 2018, our portfolio’s VaR was estimated to be 
3.02%, compared to an estimated 3.10% at December 31, 2017.

Equity  Securities,  Privately  Held  Securities  and  Other 
Investments. Our investment portfolio includes an allocation to 
equity  securities,  privately  held  securities  and  certain  other 
investments. At December 31, 2018 and 2017, the fair value of 
our investments in equity securities, privately held securities 
and certain other investments totaled $368.8 million and $576.0 
million, respectively. These securities are exposed to price risk, 
which is the potential loss arising from decreases in fair value. 
An immediate hypothetical 10% depreciation in the value of 
each position would reduce the fair value of such investments 
by  approximately  $36.9  million  and  $57.6  million  at 
December 31,  2018  and  2017,  respectively,  and  would  have 
decreased book value per share by approximately $0.09 and 
$0.14, respectively. 

Investment-Related  Derivatives. At  December 31,  2018,  the 
notional value of all derivative instruments (excluding to-be-
announced mortgage backed securities which are included in 
the fixed income securities analysis above and foreign currency 
forward contracts which are included in the foreign currency 
exchange risk analysis below) was $4.95 billion, compared to 
$2.44 billion at December 31, 2017. If the underlying exposure 
of  each  investment-related  derivative  held  at  December 31, 
2018 depreciated by 100 basis points, it would have resulted in 
a reduction in net income of approximately $49.5 million, and 
a decrease in book value per share of $0.12, compared to $24.4 
million  and  $0.06,  respectively,  on 
investment-related 
derivatives  held  at  December  31,  2017.  If  the  underlying 
exposure  of  each  investment-related  derivative  held  at 
December 31, 2018 appreciated by 100 basis points, it would 
have resulted in an increase in net income of approximately 
$49.5 million, and an increase in book value per share of $0.12, 
compared  to  $24.4  million  and  $0.06,  respectively,  on 
investment-related derivatives held at December 31, 2017. See 
note 10, “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

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 
the Company’s exposure 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

We do not believe that inflation has had a material effect on our 
consolidated results of operations, except insofar as inflation 
may affect our reserves for losses and loss adjustment expenses 
and interest rates. The potential exists, after a catastrophe loss, 
for  the  development  of  inflationary  pressures  in  a  local 
economy.  The  anticipated  effects  of  inflation  on  us  are 
considered in our catastrophe loss models. The actual effects 
of  inflation  on  our  results  cannot  be  accurately  known  until 
claims are ultimately settled.

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  10,  “Derivative  Instruments,”  to  our 
consolidated  financial  statements  in  Item  8  for  additional 
information.

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, 2018 and 2017, 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, 2018, 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, 2018,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, 2018 and 2017, and the results of its operations and its cash flows for each of the three years 
in the period ended December 31, 2018, 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, 2018, 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.

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.

requires  management 

The  preparation  of  financial  statements  in  conformity  with 
GAAP 
to  make  estimates  and 
assumptions  that  affect  the  reported  amounts  of  assets  and 
liabilities and disclosure of contingent assets and liabilities at 
the date of the financial statements and the reported amounts 
of revenues and expenses during the reporting period. Actual 
results  could  differ  materially  from  those  estimates  and 
assumptions. The Company’s principal estimates include:

•  The reserve for losses and loss adjustment expenses;

•  Reinsurance recoverable on unpaid and paid losses and loss 
for 

the  provision 

including 

adjustment  expenses, 
uncollectible amounts;

•  Estimates of written and earned premiums;

•  The valuation of the investment portfolio and assessment 

of other-than-temporary impairments (“OTTI”);

•  The valuation of purchased intangible assets;

•  The  assessment  of  goodwill  and  intangible  assets  for 

impairment; and

• 

the valuation of deferred tax assets.

The Company has reclassified the presentation of certain prior 
year information to conform to the current presentation. Such 
reclassifications had no effect on the Company’s net income, 
shareholders’ equity or cash flows.

In 2018, the shareholders approved a three-for-one stock split 
of the Company's common shares. All historical share and per 
share amounts reflect the effect of the stock split.

(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 in the Company’s 
programs,  specialty  lines,  lenders  products  business  and  for 
participation in involuntary pools. Such premium estimates are 
derived  from  multiple  sources  which  include  the  historical 
experience  of  the  underlying  business,  similar  business  and 
available  industry  information.  Unearned  premium  reserves 
represent  the  portion  of  premiums  written  that  relates  to  the 
unexpired terms of in-force insurance policies.

ARCH CAPITAL

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

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  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 
the  Company.  On  an  ongoing  basis, 
the  Company’s 
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 the Company’s 
historical experience with the brokers or ceding companies. In 
addition,  reinsurance  contracts  under  which  the  Company 
assumes business generally contain specific provisions which 
allow the Company to perform audits of the ceding company 
to  ensure  compliance  with  the  terms  and  conditions  of  the 
contract, 
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.

including  accurate  and 

timely 

Reinsurance premiums written are recorded based on the type 
of contracts the Company writes. Premiums on the 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  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  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.

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.

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  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.

The Company also writes certain reinsurance business that is 
intended to provide insurers with risk management solutions 
that complement traditional reinsurance. Under 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.

Mortgage. 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, 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 

ARCH CAPITAL

102

2018 FORM 10-K

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

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. 

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 contract. The 
Company’s  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  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 
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, the Company estimates the rate of amortization to reflect 
actual  experience  and  any  changes  to  persistency  or  loss 
development. 

insurance 

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 
anticipated 
the  expected 
profitability  of  the  Company’s  existing  mortgage  insurance 
business  and  the  need  for  a  PDR  for  its  mortgage  business 
involves significant reliance upon assumptions and estimates 
with regard to the likelihood, magnitude and timing of potential 
losses and premium revenues. 

income.  Evaluating 

interest 

No premium deficiency charges were recorded by the Company 
during 2018, 2017 or 2016.

(c) Deposit Accounting

Certain assumed reinsurance contracts that are deemed not to 
transfer  insurance  risk,  are  accounted  for  using  the  deposit 
method of accounting. However, it is possible that the Company 
could  incur  financial  losses  on  such  contracts.  Management 
exercises  significant  judgment  in  the  assumptions  used  in 
determining whether assumed contracts should be accounted 
for  as  reinsurance  contracts  or  deposit  contracts.  For  those 
contracts  that  contain  only  significant  underwriting  risk,  the 
estimated  profit  margin  is  deferred  and  amortized  over  the 
contract period and such amount is included in the Company’s 
underwriting  results.  When  the  estimated  profit  margin  is 
explicit, the margin is reflected as other underwriting income 
and any adverse financial results on such contracts are reflected 
as incurred losses. When the estimated profit margin is implicit, 
the margin is reflected as an offset to paid losses and any adverse 
financial  results  on  such  contracts  are  reflected  as  incurred 
losses. Additional judgments are required when applying the 
accounting guidance with respect to the revenue recognition 
criteria  for  contracts  deemed  to  transfer  only  significant 
underwriting  risk.  For  those  contracts  that  contain  only 
significant  timing  risk,  an  accretion  rate  is  established  at 
inception of the contract based on actuarial estimates whereby 
the  deposit  accounting  liability  is  increased  to  the  estimated 
amount payable over the contract term. The accretion on the 
deposit is based on the expected rate of return required to fund 
the  expected  future  payment  obligations.  Periodically  the 
Company  reassesses  the  estimated  ultimate  liability  and  the 
related  expected  rate  of  return. The  accretion  of  the  deposit 
accounting liability as well as changes to the estimated ultimate 
liability  and  the  accretion  rate  would  be  reflected  as  part  of 
interest expense in the Company’s results of operations. Any 
negative accretion in a deposit accounting liability is shown in 
other  underwriting  income  in  the  Company’s  results  of 
operations.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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 Accounting

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 inception 
of the reinsurance transaction, with a corresponding charge or 
credit to income.

(e) Reinsurance Ceded

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 levels of risk with other 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  7,  “Reinsurance”  for  information  on  the 
Company's  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, 
reinsurance 
subsidiaries would be liable for such defaulted amounts.

insurance  or 

(f) Cash

Cash  includes  cash  equivalents,  which  are  investments  with 
original maturities of three months or less that are not managed 
by external or internal investment advisors.

(g) Investments

The Company currently classifies substantially all of its fixed 
maturity investments and short-term 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 equities 
securities  is  generally  determined  from  quotations  received 
from  nationally  recognized  pricing  services,  or  when  such 
prices are not available, by reference to broker or underwriter 
bid indications. Short-term 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 enters into securities lending agreements with 
financial institutions to enhance investment income whereby it 
loans certain of its securities to third parties, primarily major 
brokerage firms, for short periods of time through a lending 
agent.  Such  securities  have  been  reclassified  as  “Securities 
pledged under securities lending, at fair value.” The Company 
maintains legal control over the securities it lends, retains the 
earnings and cash flows associated with the loaned securities 
and receives a fee from the borrower for the temporary use of 
the securities. Collateral received is required at a rate of 102%
or greater of the fair value of the loaned securities including 
accrued investment income and is monitored and maintained 
by the lending agent. Such collateral is reflected as “Collateral 
received under securities lending, at fair value.”

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 includes equity 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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

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

The Company invests in limited partner interests and shares of 
limited  liability  companies.  Such  amounts  are  included  in 
investments  accounted  for  using  the  equity  method,  other 
investments available for sale and investments accounted for 
using the fair value option. 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 that most significantly impact 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 performs quarterly reviews of its investments to 
determine whether declines in fair value below the cost basis 
are  considered  other-than-temporary  in  accordance  with 
applicable accounting guidance regarding the recognition and 
presentation of OTTI. The process of determining whether a 
security is other-than-temporarily impaired requires judgment 
and involves analyzing many factors. These factors include (i) 
an  analysis  of  the  liquidity,  business  prospects  and  overall 
financial condition of the issuer, (ii) the time period in which 
there was a significant decline in value, (iii) the significance of 
the decline and (iv) the analysis of specific credit events.

When  there  are  credit-related  losses  associated  with  debt 
securities for which the Company does not have an intent to 

sell and it is more likely than not that it will not be required to 
sell the security before recovery of its cost basis, the amount of 
the OTTI related to a credit loss is recognized in earnings and 
the amount of the OTTI related to other factors (e.g., interest 
rates, market conditions, etc.) is recorded as a component of 
other comprehensive income (loss). The amount of the credit 
loss of an impaired debt security is the difference between the 
amortized  cost  and  the  greater  of  (i)  the  present  value  of 
expected future cash flows and (ii) the fair value of the security. 
In instances where no credit loss exists but it is more likely than 
not that the Company will have to sell the debt security prior 
to  the  anticipated  recovery,  the  decline  in  fair  value  below 
amortized cost is recognized as an OTTI in earnings. In periods 
after  the  recognition  of  an  OTTI  on  debt  securities,  the 
Company  accounts  for  such  securities  as  if  they  had  been 
purchased on the measurement date of the OTTI at an amortized 
cost basis equal to the previous amortized cost basis less the 
OTTI  recognized  in  earnings.  For  debt  securities  for  which 
OTTI were recognized in earnings, the difference between the 
new  amortized  cost  basis  and  the  cash  flows  expected  to  be 
collected  will  be  accreted  or  amortized  into  net  investment 
income. See note 8, “Investment Information” for additional 
information.

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 differ significantly from anticipated 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 acquisition 
of the security. Such adjustments, if any, are included in net 
investment income when determined.

Investment gains or losses realized on the sale of investments, 
except for certain fund investments, are determined on a first-
in, first-out basis and are reflected in net income. Investment 
gains or losses realized on the sale of 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.

(h) Derivative Instruments

The Company recognizes all derivative instruments, including 
its 
embedded  derivative 
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 

instruments,  at  fair  value 

in

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” 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 2018, 2017, and 
2016,  the  Company  did  not  designate  any  derivative 
instruments as hedges under the relevant accounting guidance. 
See  note  10,  “Derivative  Instruments”  for  additional 
information.

(i) 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  expense  ratios  based  on 
information derived by its 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 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.  Consistent  with 
primary mortgage insurance industry accounting practice, the 
Company does not establish loss reserves for future claims on 
insured loans that are not currently delinquent (defined as two 
consecutive missed payments). 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.

such contracts, the Company is obligated to pay the claimant 
for the full amount of the claim. The Company is subsequently 
reimbursed  by  the  policyholder  for  the  deductible  amount. 
These amounts are included on a gross basis in the consolidated 
balance  sheet  in  contractholder  payables  and  contractholder 
receivables,  respectively.  In  the  event  that  the  Company  is 
unable to collect from the 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.”

(k) Foreign Exchange

Assets  and  liabilities  of  foreign  operations  whose  functional 
currency is not the U.S. Dollar are translated at the prevailing 

ARCH CAPITAL

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

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.

(l) 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  14,  “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.

(m) Share-Based Payment Arrangements

The Company applies a fair value based measurement method 
in accounting for its share-based payment 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 performance criteria. The share-based compensation 
expense  associated  with  awards  that  have  graded  vesting 
features and vest based on service conditions only is calculated 
on a straight-line basis over the requisite service period for the 
entire award. Compensation expense recognized in connection 
with performance awards is based on the achievement of the 
specified  performance  and  service  conditions.  The  final 
measure of compensation expense recognized over the requisite 
service period reflects the final performance outcome. During 
the 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  20,  “Share-Based 
Compensation”  for  information  relating  to  the  Company’s 
share-based payment awards.

(n) 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.

(o) 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.

(p) Goodwill and Intangible Assets

Goodwill  represents  the  excess  of  the  purchase  price  of  an 
acquisition 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 
impairment.  In 
performing  impairment  tests,  the  Company  may  first  assess 

indicate  a  possible 

ARCH CAPITAL

2018 FORM 10-K

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

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  the  two-step 
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  or  liabilities,  including 
favorable  or  unfavorable  contracts,  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.

(q) Recent Accounting Pronouncements

Recently Issued Accounting Standards Adopted

improving 

instruments  and  provides 

The Company adopted Financial Accounting Standards Board 
(“FASB”)  Accounting  Standard  Update  (“ASU”)  2016-01, 
“Financial  Instruments  -  Overall  (Subtopic  825-10)  - 
Recognition  and  Measurement  of  Financial  Assets  and 
Financial Liabilities,” which enhances the reporting model for 
financial 
improved  financial 
information to readers of the financial statements. Among other 
the  recognition  and 
provisions  focused  on 
measurement of financial instruments, the ASU significantly 
changes the income statement impact of equity instruments and 
the recognition of changes in fair value of financial liabilities 
attributable to an entity's own credit risk when the fair value 
option is elected. The ASU requires equity instruments that do 
not result in consolidation and are not accounted for under the 
equity method to be measured at fair value with any changes 
in  fair  value  recognized  in  net  income  rather  than  other 
comprehensive  income.  Upon  adoption  of  this  ASU,  the 
Company recorded a cumulative effect adjustment of $149.8 
million  in  retained  earnings  and  an  offsetting  decrease  in 
accumulated other comprehensive income. The adoption of this 
ASU did not have a material impact on the Company's financial 
position, cash flows, or total comprehensive income, but may 
increase  volatility  in  the  Company's  results  of  operations  in 
future periods.

The  Company  adopted  ASU  2014-09,  “Revenue  from 
Contracts with Customers (Topic 606),” which creates a new 
comprehensive revenue recognition standard that serves as a 

single  source  of  revenue  guidance  for  all  companies  in  all 
industries. The  guidance  applies  to  all  companies  that  either 
enter into contracts with customers to transfer goods or services 
or enter into contracts for the transfer of non-financial assets, 
unless those contracts are within the scope of other standards, 
such as insurance contracts or financial instruments. The ASU 
also  requires  enhanced  disclosures  about  revenue.  The 
Company adopted the ASU using the modified retrospective 
method,  whereby  the  cumulative  effect  of  adoption  was 
recognized as an adjustment to retained earnings at the date of 
initial application. The impact of the adoption of this ASU was 
not  material,  mostly  because  the  accounting  for  insurance 
contracts is outside of the scope of ASU 2014-09.

The  Company  adopted  ASU  2016-18,  “Statement  of  Cash 
Flows  (Topic  230)  - Restricted  Cash,”  which  requires  that 
restricted cash and restricted cash equivalents be included with 
cash and cash equivalents in the reconciliation of beginning and 
ending  cash  on  the  statements  of  cash  flows.  As  a  result, 
transfers between cash and cash equivalents and restricted cash 
and restricted cash equivalents will no longer be presented on 
the statement of cash flows. The revised presentation required 
in  this  ASU  is  reflected  in  the  Company’s  consolidated 
statements  of  cash  flows  for  both  periods  presented.  The 
adoption of this ASU did not have any effect on the Company’s 
results  of  operations,  financial  position  or  comprehensive 
income.

The  Company  adopted  ASU  2016-15,  “Statement  of  Cash 
Flows (Topic 230) - Classification of Certain Cash Receipts 
and Cash Payments,” which addresses several clarifications on 
the presentation and classification of certain cash receipts and 
cash payments in the statement of cash flows. Among several 
other  cash  flow  issues,  the  ASU  specifically  addresses  the 
classification  of  debt  prepayment  or  debt  issuance  costs, 
contingent  consideration  payments  made  after  a  business 
combination  and  distributions  received  from  equity  method 
investees.  The  ASU  also  provides  a  broader  principle  on 
identifying the type of activity of the cash flow item by focusing 
on the cash flow item’s nature and the predominant source or 
use  of  that  item.  The  adoption  of  this ASU  did  not  have  a 
material  impact  on  the  Company’s  consolidated  financial 
statements. 

The Company adopted ASU 2016-16, “Income Taxes (Topic 
740) - Intra-Entity Transfers of Assets Other than Inventory,” 
which  requires  entities  to  recognize  current  and  deferred 
income tax resulting from an intra-entity asset transfer when 
the  transfer  occurs.  Previously,  recognition  of  income  tax 
consequences under GAAP was not allowed until the asset had 
been sold to a third party. The adoption of this ASU did not have 
a  material  impact  on  the  Company’s  consolidated  financial 
statements.

ASU 2016-13, “Financial Instruments - Credit Losses (Topic 
326),” was issued in June, 2016. The ASU changes how entities 
will measure credit losses for most financial assets and certain 
other instruments that aren’t measured at fair value through net 
income.  The ASU  requires  an  entity  to  estimate  its  lifetime 
“expected  credit  loss”  and  record  an  allowance  that,  when 
deducted from the amortized cost basis of the financial asset, 
presents the net amount expected to be collected on the financial 
asset. The ASU is effective for the 2020 first quarter, though 
early  application  is  permitted  in  the  2019  first  quarter,  and 
should  be  applied  on  a  modified  retrospective  basis  for  the 
majority of the provisions with a cumulative-effect adjustment 
to retained earnings at the beginning of the year of adoption. 
Upon adoption, the Company expects the new standard to have 
an impact on certain type of investment securities, reinsurance 
recoverables and contractholder receivables. The Company is 
currently assessing the impact the implementation of this ASU 
will have on its consolidated financial statements. 

ASU 2017-08 “Receivables - Nonrefundable Fees and Other 
Costs (Subtopic 310-20), Premium Amortization on Purchased 
Callable  Debt  Securities,”  was  issued  in  March,  2017. This 
ASU shortens the amortization period for certain callable debt 
securities held at a premium and requires the premium to be 
amortized to the earliest call date. However, the new guidance 
does not require an accounting change for securities held at a 
discount whose discount continues to be amortized to maturity. 
The  standard  is  effective  for  financial  statements  issued  for 
fiscal  years,  and  interim  periods  within  those  fiscal  years, 
beginning  after  December  15,  2018,  with  early  adoption 
permitted. The adoption of the guidance requires a modified 
retrospective approach with a cumulative-effect adjustment to 
retained earnings. The adoption of this ASU is not expected to 
have a material effect on the Company’s consolidated financial 
statements. 

ASU 2018-02 “Income Statement-Reporting Comprehensive 
Income (Topic 220) - Reclassification of Certain Tax Effects 
from Accumulated Other Comprehensive Income,” was issued 
in February 2018 to allow the reclassification of the stranded 
tax  effects  in  accumulated  other  comprehensive  income 
(“AOCI”) resulting from the Tax Cuts and Jobs Act of 2017 
(“Tax  Cuts Act”).  Current  guidance  requires  the  effect  of  a 
change  in  tax  laws  or  rates  on  deferred  tax  balances  to  be 
reported  in  income  from  continuing  operations  in  the 
accounting period that includes the period of enactment, even 
if  the  related  income  tax  effects  were  originally  charged  or 
credited directly to AOCI. The amount of the reclassification 
would  include  the  effect  of  the  change  in  the  U.S.  federal 
corporate income tax rate on the gross deferred tax amounts 
and  related  valuation  allowances,  if  any,  at  the  date  of  the 
enactment of the Tax Cuts Act related to items in AOCI. The 
updated guidance is effective for reporting periods beginning 
after December 15, 2018 and is to be applied retrospectively to 

each period in which the effect of the Tax Cuts Act related to 
items remaining in AOCI are recognized or at the beginning of 
the  period  of  adoption.  Early  adoption  is  permitted.  The 
adoption of this ASU is not expected to have a material effect 
on the Company’s results of operations, financial position or 
liquidity. 

ASU  2018-07  “Improvements  to  Nonemployee  Share-Based 
Payment Accounting” was issued in June, 2018 to simplify the 
accounting for share-based payments granted to nonemployees 
for goods and services. Under this ASU, most of the guidance 
on such payments to nonemployees would be aligned with the 
requirements for share-based payments granted to employees. 
The ASU  is  effective  for  reporting  periods  beginning  after 
December  15,  2018.  The  Company  has  granted  share-based 
payment awards only to employees as defined by accounting 
guidance and does not expect this guidance to have a material 
impact on its consolidated financial statements. 

ASU 2018-11,“Leases: Targeted Improvements (Topic 842),” 
was issued in July, 2018. This ASU will ease implementation 
of the lease standard (ASU 2016-02). The guidance provides 
an alternative transition method by which leases are recognized 
at the date of adoption. Entities that elect this transition option 
will still be required to adopt the new leases standard using the 
modified  retrospective  transition  method  required  by  the 
standard,  but 
they  will  recognize  a  cumulative-effect 
adjustment to the opening balance of retained earnings in the 
period of adoption rather than in the earliest period presented. 
The Company will adopt this alternative transition method as 
of January 1, 2019 for leases existing at the date of adoption. 
The Company will also elect certain practical expedients that 
allow the Company not to reassess existing leases under the 
new guidance. Based on the Company’s analysis, the primary 
impact of adoption will be the recognition of a right of use asset 
and  a  lease  liability  for  operating  leases  pertaining  to  the 
Company’s real estate portfolio that are expected to represent 
less than one percent of the Company’s Total Assets and Total 
Liabilities, respectively.

ASU  2018-13,  “Fair  Value  Measurement  (Topic  820): 
Disclosure  Framework 
the  Disclosure 
Requirements  for  Fair  Value  Measurement,”  was  issued  in 
August, 2018. The ASU modifies the disclosure requirements 
on fair value measurement as part of the disclosure framework 
project  with  the  objective  to  improve  the  effectiveness  of 
disclosures  in  the  notes  to  the  financial  statements.  The 
amendments in this update allow for removal of (1) the amount 
and reasons for transfer between Level 1 and Level 2 of the fair 
value hierarchy; (2) the policy for transfers between levels; and 
(3) the valuation processes for Level 3 fair value measurements. 
The ASU is effective for fiscal years beginning after December 
15,  2019  and  interim  periods  within  those  fiscal  years.  The 
Company is currently evaluating the impact of the new guidance 
on its consolidated financial statements.

ASU 2018-15, “Intangibles - Goodwill and Other - Internal-
Use Software (Subtopic 350-40),” was issued in the 2018 third 
quarter.  This  ASU  aligns  the  requirements  for  capitalizing 
certain  implementation  costs  incurred  in  a  cloud  computing 
arrangement that is a service contract with the requirements for 
capitalizing implementation costs incurred to develop or obtain 
internal-use  software. The  standard  is  effective  for  financial 
statements issued for fiscal years, and interim periods within 
those  fiscal  years,  beginning  after  December  15,  2019,  with 
early adoption permitted. The guidance provides flexibility in 
adoption,  allowing  for  either  retrospective  adjustment  or 
prospective adjustment for all implementation costs incurred 
after the date of adoption. The Company is currently evaluating 
the impact of the new guidance on the consolidated financial 
statements.

4.  Segment Information

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

the  Company’s  consolidated 

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

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

• 

Construction and national accounts: primary and excess 
casualty coverages to middle and large accounts in the 
construction industry and a wide range of products for 
middle and large national accounts, specializing in loss 
sensitive primary casualty insurance programs (including

and  service  contract  reimbursement  products  to  banks, 
credit  unions,  automotive  dealerships  and  original 
equipment manufacturers and other specialty programs 
that pertain to automotive lending and leasing.

Professional lines: directors’ and officers’ liability, errors 
and  omissions  liability,  employment  practices  liability, 
fiduciary  liability,  crime,  professional  indemnity  and 
other  financial  related  coverages  for  corporate,  private 
equity, venture capital, real estate investment trust, limited 
partnership, financial institution and not-for-profit clients 
of all sizes and medical professional and general liability 
insurance  coverages  for  the  healthcare  industry.  The 
business is predominately written on a claims-made basis. 

Programs:  primarily  package  policies,  underwriting 
workers’ compensation and umbrella liability business in 
support of desirable package programs, targeting program 
managers  with  unique  expertise  and  niche  products 
offering general liability, commercial automobile, inland 
marine and property business with minimal catastrophe 
exposure. 

Property,  energy,  marine  and  aviation:  primary  and 
excess general property insurance coverages, including 
catastrophe-exposed property coverage, for commercial 
clients.  Coverages  for  marine  include  hull,  war,  specie 
and liability. Aviation and stand-alone terrorism are also 
offered.

Travel, accident and health: specialty travel and accident 
and  related  insurance  products  for  individual,  group 
travelers, travel agents and suppliers, as well as accident 
and  health,  which  provides  accident,  disability  and 
medical plan insurance coverages for employer groups, 
medical  plan  members,  students  and  other  participant 
groups.

other perils on a case-by-case basis. Property catastrophe 
reinsurance provides coverage on an excess of loss basis 
when aggregate losses and loss adjustment expense from 
a single occurrence of a covered peril exceed the retention 
specified in the contract.

Property  excluding  property  catastrophe:  provides 
coverage for both personal lines and commercial property 
exposures  and  principally  covers  buildings,  structures, 
equipment  and  contents.  The  primary  perils  in  this 
business include fire, explosion, collapse, riot, vandalism, 
wind, tornado, flood and earthquake. Business is assumed

that  complement 

The  mortgage  segment  includes  the  Company’s  U.S.  and 
international mortgage insurance and reinsurance operations as 
well as government sponsored enterprise (“GSE”) credit-risk 
sharing transactions. AMIC and UGRIC (combined “Arch MI 
U.S.”) are approved as eligible mortgage insurers by Federal 
National  Mortgage Association  (“Fannie  Mae”)  and  Federal 
Home  Loan  Mortgage  Corporation  (“Freddie  Mac”),  each  a 
government sponsored enterprise, or “GSE.”

investment  income,  other  income  (loss),  other  expenses 
incurred by the Company, interest expense, net realized gains 
or losses, net impairment losses included in earnings, equity in 
net income or loss of investments accounted for using the equity 
method, net foreign exchange gains or losses, transaction costs

results of the ‘other’ segment.

The ‘other’ segment includes the results of Watford Re (see note 
11,  “Variable  Interest  Entity  and  Noncontrolling  Interests”). 
Watford Re has its own management and board of directors that 
is responsible for the overall profitability of the ‘other’ segment. 
For the ‘other’ segment, performance is measured based on net 
income or loss.

(1)  The 2016 amount related to the acquisition of UGC.
(2)  During the 2018 second quarter, a subsidiary of the Company entered into a retroactive reinsurance transaction with a third party 
reinsurer to reinsure runoff liabilities associated with certain discontinued U.S. specialty casualty and program exposures.

2018 Prior Year Reserve Development

During 2018, the Company recorded estimated net favorable 
development  on  prior  year  loss  reserves  of  $272.7  million, 
which  consisted  of  $138.5  million  from  the  reinsurance 
segment,  $24.4  million  from  the  insurance  segment,  $107.6 
million from the mortgage segment and $2.2 million from the 
‘other’ segment. 

The  reinsurance  segment’s  net  favorable  development  of 
$138.5 million, or 11.0 points of net earned premium, consisted 
of $110.4 million from short-tailed lines and $28.1 million of 
net favorable development from medium-tailed and long-tailed 
lines.  Favorable  development  in  short-tailed  lines  included 
$80.8 million from property catastrophe and property other than 
property catastrophe reserves, primarily from the 2008 to 2017 
underwriting years (i.e., losses attributable to contracts having 
an  inception  or  renewal  date  within  the  given  twelve-month 
period). 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 loss ratio selections 
during 2018. Net favorable development of $28.1 million in 
medium-tailed  and  long-tailed  lines  included  reductions  in 
casualty reserves of $12.5 million, primarily from the 2002 to 
2010 underwriting years, and in marine and aviation reserves 
of $15.6 million, spread across most underwriting years. 

from  medium-tailed 

The insurance segment’s net favorable development of $24.4 
million, or 1.1 points of net earned premium, consisted of $48.4 
million  of  net  favorable  development  from  short-tailed  lines 
and  $26.3  million  of  net  favorable  development  from  long-
tailed  lines,  partially  offset  by  $50.3  million  of  net  adverse 
development 
Favorable 
development in short-tailed lines predominantly consisted of 
$50.1 million of net favorable development in property lines, 
primarily from the 2010 to 2017 accident years (i.e., the year 
in which a loss occurred), partially offset by $5.0 million of 
adverse development on travel, accident and health business 
from  the  2013  to  2017  accident  years.  Net  favorable 
development  in  long-tailed  lines  of  $26.3  million  included 
$19.7  million  of  net  favorable  development  on  executive 

lines.

assurance business, primarily from the 2015 accident year, and 
$1.4 million of net favorable development in casualty business, 
primarily from the 2009 to 2015 accident years. Net adverse 
development  in  medium  tailed  lines  of  $50.3  million  was 
primarily due to net adverse development in contract binding 
business for accident years 2013 to 2017.

The mortgage segment’s net favorable development of $107.6 
million, or 9.1 points of net earned premium, included $103.4 
million of favorable development on U.S. primary mortgage 
business. Such development was primarily driven by lower than 
expected claim emergence across most origination years and 
also  reflected  $26.3  million  related  to  second  lien  and  other 
portfolios, primarily due to subrogation recoveries.

2017 Prior Year Reserve Development

During 2017, the Company recorded estimated net favorable 
development  on  prior  year  loss  reserves  of  $238.0  million, 
which  consisted  of  $165.4  million  from  the  reinsurance 
segment, $8.6 million from the insurance segment and $95.0 
million from the mortgage segment, less adverse development 
of $31.0 million from the ‘other’ segment. 

The  reinsurance  segment’s  net  favorable  development  of 
$165.4 million, or 14.5 points of net earned premium, consisted 
of $101.0 million from short-tailed lines and $64.4 million of 
net favorable development from medium-tailed and long-tailed 
lines.  Favorable  development  in  short-tailed  lines  included 
$82.6 million from property catastrophe and property other than 
property catastrophe reserves, primarily from the 2009 to 2016 
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  loss 
ratio  selections  during  2017.  Net  favorable  development  of 
$64.4 million in medium-tailed and long-tailed lines included 
reductions in casualty reserves of $43.7 million, primarily from 
the 2002 to 2013 underwriting years, and in marine and aviation 
reserves  of  $19.6  million,  spread  across  most  underwriting 
years.

from  medium-tailed 

The  insurance  segment’s  net  favorable  development  of  $8.6 
million, or 4.0 points of net earned premium, consisted of $14.9 
million  of  net  favorable  development  from  short-tailed  lines 
and  $11.8  million  of  net  favorable  development  from  long-
tailed  lines,  partially  offset  by  $18.1  million  of  net  adverse 
development 
Favorable 
development in short-tailed lines predominantly consisted of 
$22.8 million of net favorable development in property lines, 
primarily from the 2011 to 2016 accident years, partially offset 
by $11.8 million of adverse development on travel, accident 
and health business from the 2014 to 2016 accident years. Net 
favorable  development  in  long-tailed  lines  of  $11.8  million

executive assurance business, primarily from the 2013 accident 

lines. 

year, and $8.3 million of net favorable development in casualty 
business, primarily from the 2007 to 2013 accident years. Net 
adverse development in medium-tailed lines of $18.1 million
included $56.3 million of net adverse development in program 
business, primarily from the 2013 to 2015 accident years and 
primarily  driven  by  a  few  inactive  programs  that  were  non-
renewed in 2015 and early in 2016, partially offset by $36.2 
million of net favorable development in professional liability 
business, primarily from the 2010 to 2016 accident years.

The mortgage segment’s net favorable development of $95.0 
million, or 9.0 points of net earned premium, for 2017, included 
$89.3  million  of  favorable  development  on  U.S.  primary 
mortgage business. Such development was primarily driven by 
lower than expected claim emergence across most origination 
years and also reflected $33.8 million related to second lien and 
other portfolios, primarily due to subrogation recoveries.

2016 Prior Year Reserve Development

During 2016, the Company recorded estimated net favorable 
development on prior year loss reserves of $270 million, which 
consisted  of  $218.8  million  from  the  reinsurance  segment, 
$33.1 million from the insurance segment, $21.2 million from 
the mortgage segment less adverse development of $3.1 million
from the ‘other’ segment. 

The  reinsurance  segment’s  net  favorable  development  of 
$218.8 million, or 20.7 points of net earned premium, consisted 
of $133.8 million from short-tailed lines and $85.0 million of 
net favorable development from medium-tailed and long-tailed 
lines.  Favorable  development  in  short-tailed  lines  included 
$113.6 million from property catastrophe and property other 
than property catastrophe reserves, primarily from the 2009 to 
2015 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 
loss ratio selections during 2016. Net favorable development 
of $85.0 million in medium-tailed and long-tailed lines included 
reductions in casualty reserves of $86.1 million, primarily from 
the 2002 to 2013 underwriting years.

The insurance segment’s net favorable development of $33.1 
million, or 1.6 points of net earned premium, consisted of $8.7 
million  of  net  favorable  development  from  short-tailed  lines 
and $24.4 million of net favorable development from medium-
tailed and long-tailed lines. Favorable development in short-
tailed  lines  predominantly  consisted  of  $17.2  million  of  net 
favorable  development  in  property  lines,  primarily  from  the 
2008 to 2014 accident years, partially offset by $11.1 million
of adverse development on travel, accident and health business 
from  the  2012  to  2015  accident  years.  Net  favorable

years,  partially  offset  by  $33.1  million  of  net  adverse 
development in program business, primarily from the 2013 to 
2015  accident  years.  The  adverse  development  in  program 
business was primarily driven by a few inactive programs that 
were non-renewed in 2015 and early in 2016.

The mortgage segment’s net favorable development of $21.2 
million, or 7.4 points of net earned premium, for 2016, included 
$18.5  million  of  favorable  development  on  U.S.  primary 
mortgage  business,  reflecting  a  decrease  in  the  number  of 
delinquent loans and a lower claim rate on such loans. Such 
development was primarily from the 2004 to 2008 and 2014 
origination years. The mortgage segment also experienced net 
favorable  development  of  $2.7  million  on  U.S.  mortgage 
reinsurance 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 (1) 
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  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  reserves 
involves  a  considerable  degree  of  judgment  by  management 
and, as of any given date, is inherently uncertain.

The Company determined the following to be insignificant for 
disclosure purposes: (i) amounts included in the ‘other’ segment

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 
in estimating ultimate losses and loss adjustment expenses are 
magnified by the length of the time lag between when a claim 
actually occurs and when it is reported and settled. This time 
lag  is  sometimes  referred  to  as  the  “claim-tail.”  During  this 
period  additional  facts  regarding  coverages  written  in  prior 
accident years, as well as about actual claims and trends, may 
become known and, as a result, may lead to adjustments of the 
related  Loss  Reserves.  If  the  Company  determines  that  an 
adjustment  is  appropriate,  the  adjustment  is  recorded  in  the 
accounting  period  in  which  such  determination  is  made. 
Accordingly,  should  Loss  Reserves  need  to  be  increased  or 
decreased  in  the  future  from  amounts  currently  established, 
future results of operations would be negatively or positively 
impacted  respectively.  The  Company  authorizes  managing 
general  agents,  general  agents  and  other  producers  to  write 
program business on the Company’s behalf within prescribed 
underwriting  authorities.  This  delegated  authority  process 
introduces additional complexity to the actuarial determination 
of unpaid future losses and loss adjustment expenses. In order 
to monitor adherence to the underwriting guidelines given to 
such parties, the Company periodically performs underwriting 
and claims due diligence reviews.

In determining ultimate losses and loss adjustment expenses, 
the cost to indemnify claimants, provide needed legal defense 
and other services for insureds and administer 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 to 
isolate or quantify and 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 the facts and circumstances at the time the 
estimates of Loss Reserves are made. 

These  methods  generally  fall  into  one  of  the  following 
categories  or  are  hybrids  of  one  or  more  of  the  following 
categories:

•  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 typically developed based upon 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 
loss 
known  claims.  However,  historical 
development  methods  necessarily  assume  that  case 
reserving  practices  are  consistently  applied  over  time. 
Therefore,  when  there  have  been  significant  changes  in 
how case reserves are established, using incurred loss data 
to project ultimate losses may be less reliable than other 
methods.

incurred 

•  Historical paid loss development methods - these methods, 
like historical incurred 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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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  losses  than  cumulative 
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  lenders 
products), 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 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  historical  paid  and  incurred  loss 
development methods in the reserving process. The Company 
makes a number of key assumptions in their reserving process, 
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 
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 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  industry  loss  development 
patterns  and  adjusted  to  reflect  differences  in  the  insurance 
segment’s  mix  of  business,  are  reasonable  and  that  claims

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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. 

In 2018, the Company entered into a loss portfolio transfer and 
adverse development cover reinsurance agreement accounted 

for as retroactive reinsurance.  The agreement transfers Loss 
Reserves  and  future  favorable  or  adverse  development  on 
certain runoff programs, within multi-line and other specialty 
business,  and  certain  third  party  occurrence  business  (the 
“Covered  Lines”). As  incurred  losses  and  allocated  loss 
adjustment  expenses  for  the  Covered  Lines  are  ceded  to  the 
reinsurer, the Company is not exposed to changes in the amount, 
timing and uncertainty of cash flows arising from the Covered 
Lines.  To avoid distortion, the incurred losses and allocated 
loss adjustment expenses and cumulative paid losses and loss 
adjustment  expenses  for  the  Covered  Lines  are  excluded 
entirely  from  the  tables  below.   Reinsurance  recoverables  at 
December  31,  2018  included  $245.8  million  related  to  this 
reinsurance agreement.

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 based upon the amount of 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 
liability,  claims  from 
interpretations  of  coverage  and 
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

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

segment  devote 

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

statistics normally include historical premium and loss data by 
class  of  business,  individual  claim  information  for  larger

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

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 
facts  and 
circumstances at the time the estimates of Loss Reserves are 
made.

the 

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, 2018 there were no significant backlogs related 
to  the  processing  of  assumed  reinsurance  information  at  our 
reinsurance operations.

The reinsurance segment relies heavily on information reported 
by ceding companies, as discussed above. In order to determine 
information, 
the  accuracy  and  completeness  of  such 
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 

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 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 to potential 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  structure,  estimates  of 
catastrophe  losses,  terms  and  conditions  and  geographical 
distribution. As losses in 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.

In the initial reserving process for medium-tail and long-tail 
reinsurance lines (consisting of casualty, other specialty, marine 
and aviation and other exposures), the Company primarily relies 
on the expected loss method. The development of medium-tail 
and long-tail business may be unstable, especially if there are 
high severity major events, with business written on an excess 
of loss basis typically having a longer tail than business written 
on a pro rata basis. 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 methods in the reserving process. Our reinsurance 
operations make a number of key assumptions in reserving for 

medium-tail and long-tail lines, including that the pricing loss 
ratio is the best estimate of the ultimate loss ratio at the time 
the  contract  is  entered  into,  historical  paid  and  reported 
development  patterns  are  stable  and  claims  personnel  and 
underwriters  analyses  of  our  exposure  to  major  events  are 
assumed to be our best estimate of our exposure to the known 
claims on those events. The expected loss ratios used in our 
reinsurance operations’ initial reserving process for medium-
tail and long-tail contracts have varied over time due to changes 
in pricing, terms and conditions and reinsurance structure. As 
the credibility of historical experience for earlier underwriting 
years increases, the experience from these underwriting years 
will  be  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.

Mortgage Segment

The Company’s mortgage segment includes (1) direct mortgage 
insurance in the U.S., (2) direct mortgage insurance in Europe, 
(3) global mortgage reinsurance and (4) participation in various 
GSE credit risk-sharing products, with the latter three categories 
along with second lien and student loan exposures excluded on 
the  basis  of  insignificance  for  the  purposes  of  presenting 
disclosures related to short duration contracts.

For  direct  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’s  U.S. 
mortgage insurance operations also reserve 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 payments in arrears. The actuarial reviews 
and  documentation  created  in  the  reserving  process  are 
completed  in  accordance  with  generally  accepted  actuarial 
standards.  The  selected  assumptions  reflect  the  actuary’s 
judgment  based  on  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 accounting 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 lead methodology used by the Company is a frequency-
severity  method  based  on 
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 

the 

provided (“risk size”) on those loans by directly relating the 
reserves to these amounts. The delinquencies are grouped into 
homogeneous cohorts for analysis, reflecting product type and 
age  of  delinquency. A  claim  rate  is  then  developed  for  each 
cohort  which  represents  the  frequency  with  which  the 
delinquencies become claims. The claim 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 
in  home  prices  and  unemployment.  Claim  rates  can  vary 
materially  by  age  of  delinquency,  depending  on  the  mix  of 
delinquencies and economic conditions.

Claim size 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. 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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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.

The tables below include the acquired business of UGC across all periods presented. Due to the length of time for which claims 
incurred typically remain outstanding prior to payment and the Company’s formation of the mortgage segment in 2014, the Company 
determined that seven accident years was sufficient for its current disclosures. The following table presents information on the 
mortgage segment’s short-duration insurance contracts:

Other Segment

Loss  Reserves  for  the  ‘other’  segment  (i.e., Watford  Re)  are 
comprised of case reserves, ACRs and IBNR reserves. For all 
business  assumed  by  Watford  Re,  the  Company  acts  as 
reinsurance underwriting manager, provides actuarial and risk 
management services and recommends a level of Loss Reserves 
to Watford Re. The Company does not guarantee or provide 
credit  support  for Watford  Re,  and  the  Company’s  financial 
exposure to Watford Re is limited to its investment in Watford 
Re’s common and preferred shares and counterparty credit risk 
(mitigated  by  collateral)  arising  from 
the  reinsurance 
transactions. The estimation of Loss Reserves for Watford Re 
is  subject  to  the  same  risk  factors  as  the  estimation  of  Loss 
Reserves  for  the  Company’s  insurance,  reinsurance  and 
mortgage segments as described earlier. Watford Re performs 
its own reserve reviews and sets its reserves independently. As 
noted previously, the Company determined that amounts in the 

‘other’  segment  are  insignificant  for  the  purposes  of  these 
footnote disclosures.

For the year ended December 31, 2018, the Company did not 
make  any  significant  changes  in  its  methodologies  or 
assumptions as described above (a) to determine the presented 
amounts of IBNR reserves, (b) for expected development on 
case reserves.

The  Company  measures  claim  frequency  information  on  an 
individual claim count basis. Claim counts are provided for the 
insurance and mortgage segments, where reliable information 
is available. For insurance business, any claim which is reported 
to  the  Company  is  included  in  the  count,  even  if  it  is 
subsequently  settled  without  liability  to  the  Company.  The 
Company does not include claim count information for losses 
from  U.S.  insurance  pool  business  where  individual  loss 
information  is  unavailable  and  impracticable  to  obtain.  For 
mortgage  business,  only  delinquencies  which  subsequently

130

2018 FORM 10-K

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

become claims are included in the claim count. For reinsurance 
business, claim counts are not provided. A significant amount 
of  the  Company’s  reinsurance  business  is  written  on  a 
proportional  basis,  for  which  individual  loss  information  is 
typically unavailable and impracticable to obtain.

For the year ended December 31, 2018, the Company did not 
make  any  significant  changes  in  its  methodologies  or 
assumptions  as  described  above  to  calculate  the  cumulative 
claim frequency.

7.  Reinsurance

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.  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  reinsurance  subsidiaries  may  purchase 
retrocessional  coverage  as  part  of  their  risk  management 
program.  Reinsurance  recoverables  are  recorded  as  assets, 
predicated on the reinsurers’ ability to meet their obligations 
under the reinsurance agreements. If the reinsurers are unable 
to satisfy their obligations under the agreements, the Company’s 
insurance or reinsurance subsidiaries would be liable for such 
defaulted amounts.

The effects of reinsurance on the Company’s written and earned 
premiums  and  losses  and  loss  adjustment  expenses  with 
unaffiliated reinsurers were as follows:

Reinsurance Recoverables

The Company monitors the financial condition of its reinsurers 
and  attempts  to  place  coverages  only  with  substantial, 
financially  sound  carriers.  Although  the  Company  has  not 
experienced any material credit losses to date, an inability of 
its reinsurers or retrocessionaires to meet their obligations to it 
over the relevant exposure periods for any reason could have a 
material adverse effect on its financial condition and results of 
operations.  The  following  table  summarizes  the  Company’s 
reinsurance  recoverables  on  paid  and  unpaid  losses  (not

The Company has entered into various aggregate excess of loss 
mortgage reinsurance agreements with various special purpose

reinsurance 
“Bellemeade  Agreements”).  For  the  respective  coverage 
periods, the  Company will retain the first layer of the respective 
aggregate losses and the special purpose reinsurance companies

In securities lending transactions, the Company receives collateral in excess of the fair value of the fixed maturities pledged. For purposes of this table, the 
Company has excluded the collateral received under securities lending, at fair value and included the securities pledged under securities lending, at fair value. 
See “—Securities Lending Agreements.”

(2)  Represents the total OTTI recognized in accumulated other comprehensive income (“AOCI”). It does not include the change in fair value subsequent to the 
impairment measurement date. At December 31, 2018, the net unrealized gain related to securities for which a non-credit OTTI was recognized in AOCI 
was nil, compared to a net unrealized loss of $0.3 million at December 31, 2017.

(3)  Effective January 1, 2018, the Company adopted new accounting guidance for financial instruments (see Note 3). As a result, equity securities are no longer 

accounted for as available for sale and are excluded from this table.

In securities lending transactions, the Company receives collateral in excess of the fair value of the fixed maturities pledged. For purposes of this table, the 
Company has excluded the collateral received and reinvested and included the fixed maturities pledged. See “—Securities Lending Agreements.”

Securities Lending Agreements

The Company enters into securities lending agreements with financial institutions to enhance investment income whereby it loans 
certain of its securities to third parties, primarily major brokerage firms, for short periods of time through a lending agent. The 
Company maintains legal control over the securities it lends, retains the earnings and cash flows associated with the loaned securities 
and receives a fee from the borrower for the temporary use of the securities. An indemnification agreement with the lending agent 
protects the Company in the event a borrower becomes insolvent or fails to return any of the securities on loan to the Company.

The Company receives collateral in the form of cash or securities. Cash collateral primarily consists of short-term investments. 
At December 31, 2018, the fair value of the cash collateral received on securities lending was $19.0 million and the fair value of 
security collateral received was $255.1 million. At December 31, 2017, the fair value of the cash collateral received on securities 
lending was $199.9 million and the fair value of security collateral received was $276.7 million.

(1)  The  Company  reviewed  the  accounting  treatment  for  three  limited 
partnership investments which were accounted for as available for sale 
at December 31, 2017 during the 2018 first quarter and determined, based 
on  reconsideration  during  the  period  of  the  Company’s  percentage

investments.

In  applying  the  equity  method,  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.

investments  accounted  for  using  the  equity  method  is  as

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  redemption 
requests exceeds a 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 
the initial amount of time an investor 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.

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.’ Based on the new accounting guidance for 
consolidation,  the  Company  determined  that  these  limited 
partnership interests represented variable interests in the funds 
because the general partner did not have a significant interest 
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.

A description of the methodology and significant inputs used 
to measure the amount of net impairment losses recognized in 
earnings in 2018 is as follows:

•  Corporate  bonds  –  the  Company  reviewed  the  business 
prospects,  credit  ratings,  estimated  loss  given  default 
factors, foreign currency impacts and information received 
from  asset  managers  and  rating  agencies  for  certain 
corporate bonds. Impairment losses were primarily from 
foreign currency impacts;

•  Mortgage  backed  securities  –  the  Company  utilized 
underlying  data  provided  by  asset  managers,  cash  flow 
projections  and  additional 
information  from  credit 
agencies in order to determine an expected recovery value 
for each security;

•  Equity  securities  –  the  Company  utilized  information 
received  from  asset  managers  on  common  stocks, 
including the business prospects, recent events, industry 
and market data and other factors. Impairment losses were 
primarily  on  equities  which  were  in  an  unrealized  loss 
position for a significant length of time.

The Company believes that the OTTI included in accumulated 
other  comprehensive  income  at  December 31,  2018  on  the 
securities  which  were  considered  by  the  Company  to  be 

The Company is required to maintain assets on deposit, which 
primarily consist of fixed maturities, with various regulatory 
authorities to support its insurance and reinsurance operations. 
The  Company’s 
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.

9.  Fair Value

Accounting  guidance  regarding  fair  value  measurements 
addresses how companies should measure fair value when they 
are  required  to  use  a  fair  value  measure  for  recognition  or 
disclosure  purposes  under  GAAP  and  provides  a  common 
definition of fair value to be used throughout GAAP. It defines 
fair value as the price that would be received to sell an asset or 
paid to transfer a liability in an orderly fashion between market 
participants at the measurement date. In addition, it establishes 
a three-level valuation hierarchy for the disclosure of fair value 
measurements.  The  valuation  hierarchy  is  based  upon  the 
transparency of inputs to the valuation of an asset or liability 
as of the measurement date. The level in the hierarchy within 
which a given fair value measurement falls is determined based 
on the lowest level input that is significant to the measurement 
(Level 1 being the highest priority and Level 3 being the lowest 
priority).

The levels in the hierarchy are defined as follows:

Level 1: 

Level 2: 

Level 3: 

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

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 
the  proper  classification  of  such 
value  and  discusses 
investments with investment advisers and others.

The  Company  determines  the  existence  of  an  active  market 
based on its judgment as to whether transactions for the financial 

to  provide 

reliable  pricing 

instrument occur in such market with sufficient frequency and 
information.  The 
volume 
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 
from  broker-dealers  who  are  active  in  the  corresponding 
markets. Such quotes are subject to the validation procedures 
noted  above.  Of  the  $20.4  billion  of  financial  assets  and 
liabilities  measured  at  fair  value  at  December 31,  2018, 
approximately $217.9 million, or 1.1%, were priced using non-
binding broker-dealer quotes. Of the $20.9 billion of financial 
assets  and  liabilities  measured  at  fair  value  at  December 31, 
2017, approximately $181.5 million, or 0.9%, were priced using 
non-binding broker-dealer quotes.

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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

source uses observable market inputs including, but not limited 
to, investment yields, credit risks and spreads, benchmarking 
of  like  securities,  broker-dealer  quotes,  reported  trades  and 
sector  groupings  to  determine  a  reasonable  fair  value.  The 
following  describes  the  significant  inputs  generally  used  to 
determine  the  fair  value  of  the  Company’s  fixed  maturity 
securities by asset class:

•  U.S. government and government agencies — valuations 
provided  by  independent  pricing  services,  with  all  prices 
provided  through  index  providers  and  pricing  vendors.  The 
Company  determined  that  all  U.S.  Treasuries  would  be 
classified as Level 1 securities due to observed levels of trading 
activity, the high number of strongly correlated pricing quotes 
received on U.S. Treasuries and other factors. The fair values 
of U.S. government agency securities are generally determined 
using the spread above the risk-free yield curve. As the yields 
for the risk-free yield curve and the spreads for these securities 
are observable market inputs, the fair values of U.S. government 
agency securities are classified within Level 2.

•  Corporate bonds — valuations provided by independent 
pricing services, substantially all through index providers and 
pricing vendors with a small amount through broker-dealers. 
The  fair  values  of  these  securities  are  generally  determined 
using the spread above the risk-free yield curve. These spreads 
are generally obtained from the new issue market, secondary 
trading  and  from  broker-dealers  who  trade  in  the  relevant 
security market. As the significant inputs used in the pricing 
process for corporate bonds are observable market inputs, the 
fair value of these securities are classified within Level 2.

•  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.

Other investments

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 a low level 
of transparency on the inputs used in the pricing process. The 
fair values for certain of the Company’s other investments are

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

determined using net asset values as advised by external fund 
managers,  based  on  the  fund  manager’s  valuation  of  the 
underlying holdings in accordance with the fund’s governing 
documents. Certain investments that are measured at fair value 
using the net asset value per share (or its equivalent) practical 
expedient have not been classified in the fair value hierarchy. 

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.

Contingent consideration liabilities

liabilities  (included 

Contingent  consideration 
in  ‘other 
liabilities’ in the consolidated balance sheets) include amounts 
related to the Company’s 2014 acquisition of CMG Mortgage 
Insurance  Company  and  its  affiliated  mortgage  insurance 
companies (the “CMG Entities”) and other acquisitions. Such 
amounts 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 
the  Company  estimates  future 
liabilities, 
payments using an income approach based on modeled inputs 
which include a weighted average cost of capital. The Company 
determined that contingent consideration liabilities would be 
included within Level 3.

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, 2018, 
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,  2018,  the  Company’s  senior  notes  were 
carried at their cost, net of debt issuance costs, of $1.73 billion 
and had a fair value of $1.88 billion. At December 31, 2017, 
the Company’s senior notes were carried at their cost, net of 
debt issuance costs, of $1.73 billion and had a fair value of $2.04 
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.

The Company measures the fair value of certain assets on a 
non-recurring  basis,  generally  quarterly,  annually,  or  when 
events or changes in circumstances indicate that the carrying 
amount  of  the  assets  may  not  be  recoverable.  These  assets 
include  investments  accounted  for  using  the  equity  method, 
certain other investments, goodwill and intangible assets, and 
long-lived assets. The Company uses a variety of techniques to 
measure  the  fair  value  of  these  assets  when  appropriate,  as 
described below: 

Investments accounted for using the equity method. When the 
Company determines that the carrying value of these assets may 
not be recoverable, the Company records the assets at fair value 
with the loss recognized in income. In such cases, the Company 
measures  the  fair  value  of  these  assets  using  the  techniques 
discussed above in “—Fair Value Measurements on a Recurring 
Basis.”

Goodwill and Intangible Assets. The Company tests goodwill 
and  intangible  assets  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. 

10.  Derivative Instruments

The  Company’s  investment  strategy  allows  for  the  use  of 
derivative instruments. The Company’s derivative 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  routinely  utilizes  foreign 
currency  forward  contracts,  currency  options,  index  futures 
contracts  and  other  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.

In addition, the Company purchases to-be-announced mortgage 
backed securities (“TBAs”) as part of its investment strategy. 
TBAs represent commitments to 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 following table summarizes information on the fair values 
and notional values of the Company’s derivative instruments:

contracts, consisting of long and short positions.

(2)  The fair value of asset derivatives are included in ‘other assets’ 
and the fair value of liability derivatives are included in ‘other 
liabilities.’ Such amounts include risk in force on GSE credit-risk 
sharing transactions that are accounted for as derivatives. 
(3)  The fair value of TBAs are included in ‘fixed maturities available 

for sale, at fair value.’

The  Company  did  not  hold  any  derivatives  which  were 
designated  as  hedging  instruments  at  December 31,  2018  or 
2017. 

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. Effectively, 
contractual  close-out  netting  reduces the  derivatives credit 
exposure from a gross to a net exposure. At December 31, 2018, 
$80.4  million  and  $18.9  million,  respectively,  of  asset 
derivatives and liability derivatives were subject to a master 
netting agreement compared to $40.6 million and $19.6 million, 
respectively, at December 31, 2017. The remaining derivatives

be  reflected  in  a  separate  operating  segment  (‘other’)  and 
provides the income statement and total investable assets, total 
assets and total liabilities of Watford Re within Note 4. 

Because Watford Re is an independent company, the assets of 
Watford Re can be used only to settle obligations of Watford 
Re and Watford Re is solely responsible for its own liabilities 
and  commitments.  The  Company’s  financial  exposure  to 
Watford Re is limited to its investment in Watford Re’s common 
shares  and  counterparty  credit  risk  (mitigated  by  collateral) 
arising from the reinsurance transactions.

The following table provides the carrying amount and balance 
sheet caption in which the assets and liabilities of Watford Re 
are reported:

Watford Holdings Ltd.

In March 2014, Watford Re raised approximately $1.1 billion 
of  capital  consisting  of  $907.3  million  in  common  equity 
($895.6 million net of issuance costs) and $226.6 million in 
preference  equity  ($219.2  million  net  of  issuance  costs  and 
discount). The Company invested $100.0 million and acquired 
2,500,000  common  shares,  approximately  11%  of  Watford 
Holdings Ltd.’s common equity, and a warrant to purchase up 
to 975,503 additional common shares. The warrants expire on 
March 31, 2020, and are exercisable at any time following the 
listing  of  the  common  shares  on  a  U.S.  national  securities 
exchange. The exercise price of the warrants is determined on 
the date of exercise based on certain targeted returns for existing 
common shareholders. As of December 31, 2018, the exercise 
price was $77.94 per share.

Bellemeade Re

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). 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.

Non-redeemable noncontrolling interests

The Company accounts for the portion of Watford Re’s common 
equity attributable to third party investors in the shareholders’ 
equity  section  of  its  consolidated  balance  sheets.  The 
noncontrolling ownership in Watford Re’s common shares was 
approximately  89%  at  December 31,  2018.  The  portion  of 
Watford Re’s income or loss attributable to third party investors 
is  recorded  in  the  consolidated  statements  of  income  in  ‘net 
(income) loss attributable to noncontrolling interests.’

The Company accounts for redeemable noncontrolling interests 
in the mezzanine section of its consolidated balance sheet. Such 
redeemable  noncontrolling  interests  relate  to  the  9,065,200 
cumulative redeemable preference shares (“Watford Preference 
Shares”) issued in late March 2014 with a par value of $0.01 
per share and a liquidation preference of $25.00 per share. The 
Watford Preference Shares were issued at a discounted amount 
of $24.50 per share. Holders of the Watford Preference Shares 
will be entitled to receive, if declared by Watford Re’s board, 
quarterly  cash  dividends  on  the  last  day  of  March,  June, 
September,  and  December.  Dividends  will  accrue  from  the 
closing date to June 30, 2019 at a fixed rate of 8.5% per annum. 
From  June  30,  2019  and  subsequent,  dividends  will  accrue 
based on a floating rate equal to the 3 month U.S. dollar LIBOR 
(with a 1% floor) plus a margin based on the difference between 
the fixed rate and the 5 year mid swap rate to the floating rate 
as  set  out  on  the  Bloomberg  Screen  IRSB  18.  The  Watford 
Preference Shares may be redeemed by Watford Re on or after 
June 30, 2019 or at the option of the preferred shareholders at 
any time on or after June 30, 2034. Because the redemption 
features are not solely within the control of Watford Re, the 
Company accounts for the redeemable noncontrolling interests 
in the Watford Preference Shares in the mezzanine section of 
its  consolidated  balance  sheets.  Preferred  dividends  on  the 
Watford  Preference  Shares,  including  the  accretion  of  the 
discount and issuance costs, was $19.6 million for 2018, 2017 
and 2016. Preferred dividends, including the accretion of the 
discount  and  issuance  costs,  are  included  in  ‘amounts 
attributable  to  noncontrolling  interests’  in  the  Company’s 
consolidated statements of income.

13.  Earnings Per Common Share

The calculation of basic earnings per common share is computed by dividing income available to Arch common shareholders by 
the weighted average number of Common Shares and common share equivalents outstanding. The following table sets forth the

(1)   The company has determined that, based on a review of the terms, features and rights of the Company’s non-voting common equivalent preferred shares 
compared to the rights of the Company’s common shareholders, the underlying common shares that the convertible securities convert to were common 
share equivalents at the time of their issuance.

(2)  Certain stock options were not included in the computation of diluted earnings per share where the exercise price of the stock options exceeded the average 
market price and would have been anti-dilutive or where, when applying the treasury stock method to in-the-money options, the sum of the proceeds, 
including unrecognized compensation, exceeded the average market price and would have been anti-dilutive. For 2018, 2017 and 2016, the number of stock 
options excluded were 5,673,821, 2,603,451 and 2,168,187, respectively.

14.   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. tax under 
an applicable income tax treaty with the U.S. 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  its  non-U.S.  subsidiaries  intend  to 
conduct 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 are engaged in a trade or business in the 
United States. If Arch Capital or any of its non-U.S. subsidiaries

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

were subject to U.S. income tax, Arch Capital’s shareholders’ 
equity  and  earnings  could  be  materially  adversely  affected. 
Arch  Capital  has  subsidiaries  and  branches  that  operate  in 
various jurisdictions around the world that are subject to tax in 
the  jurisdictions  in  which  they  operate.  The  significant 
jurisdictions in which Arch Capital’s subsidiaries and branches 
are  subject  to  tax  are  the  United  States,  United  Kingdom, 
Ireland, Canada, Switzerland, Australia and Denmark.

The components of income taxes attributable to operations were 
as follows:

The expected tax provision computed on pre-tax income or loss 
at the weighted average tax rate has been calculated as the sum 
of the pre-tax income in each jurisdiction multiplied by that 
jurisdiction’s applicable statutory tax rate. The 2018 applicable 
statutory  tax  rates  by  jurisdiction  were  as  follows:  Bermuda 
(0.0%),  United  States  (21.0%),  United  Kingdom  (19.0%), 
Ireland (12.5%), Denmark (22.0%), Canada (26.5%), Gibraltar 
(10.0%),  Australia  (30.0%),  Hong  Kong  (16.5%)  and  the 
Netherlands (20.0%). The United States rate was 35% in 2017 
and 2016.

income taxes and the expected tax provision at the weighted 
average tax rate follows:

The effect of a change in tax laws or rates on deferred taxes 
assets and liabilities is recognized in income in the period in 
which such change is enacted. 

On December 22, 2017, the Tax Cuts Act was signed into law 
by  the  President  of  the  United  States  which  significantly 
changes the U.S. tax law in many way including a reduction of 
the U.S. federal income tax rate from 35% to 21% effective 
January 1, 2018. Also on December 22, 2017, the Securities 
and Exchange Commission issued, Staff Accounting Bulletin 
No. 118 (“SAB 118”) which provides guidance on accounting 
for  tax  effects  of  the  Tax  Cuts  Act.  SAB  118  provided  a 
measurement period of up to one year from the enactment date 
to  complete  the  accounting.  During  2018,  the  Company 
finalized its accounting for the income tax impact of the Tax 
Cuts Act resulting in a tax expense of $1.2 million primarily 
attributable  to  the  write  down  of  temporary  differences 
identified following the filing of the Company’s 2017 corporate 
tax return offset by AMT credits that are currently recoverable.

The Company provides a valuation allowance to reduce certain 
deferred tax assets to an amount which management expects to 
more likely than not be realized. As of December 31, 2018, the 
Company’s valuation allowance was $44.7 million, compared 
to  $30.6  million  at  December 31,  2017.  The  valuation 
allowance  in  both  periods  was  primarily  attributable  to 
valuation  allowance  on  the  Company’s  U.K.  Canadian  and 
Australian  operations  and  certain  other  deferred  tax  assets 
relating to loss carryforwards that have a limited use.

At  December 31,  2018,  the  Company’s  net  operating  loss 
carryforwards and tax credits were as follows:

(1) Includes $4.6 million net operating loss carryforwards from Watford Re.

(2) 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 
$9.6 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 $182.7 million at December 31, 2018, 
compared to $177.2 million at December 31, 2017.

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, 2018, the Company’s total unrecognized tax 
benefits, including interest and penalties, were $2.0 million. If 
recognized,  the  full  amount  of  the  unrecognized  tax  benefit 
would generally decrease the current year annual effective tax 
rate. A reconciliation of the beginning and ending amount of

15.  Transactions with Related Parties

Kewsong  Lee,  a  director  of Arch  Capital  until  November  2, 
2017, resigned from Arch Capital’s Board of Directors because 
of the expansion of his duties at The Carlyle Group (“Carlyle”) 
following his promotion to co-CEO effective January 1, 2018. 
As part of its investment philosophy, the Company invests a 
portion  of  its  investment  portfolio  in  alternative  investment 
funds.  As  of  December 31,  2017,  the  total  value  of  the 
Company’s investments in funds or other investments managed 
by Carlyle was approximately $293.0 million, and the Company 
had  aggregate  unfunded  commitments  to  funds  managed  by 
Carlyle of $468.8 million. The Company may make additional 
commitments to funds managed by Carlyle from time to time. 
During 2017 and 2016, the Company made aggregate capital 
contributions to funds managed by Carlyle of $131.8 million
and  $62.1  million,  respectively.  During  2017  and  2016,  the 
Company  received  aggregate  cash  distributions  from  funds 
managed  by  Carlyle  of  $55.6  million  and  $21.5  million, 
respectively. 

Certain directors and executive officers of the Company own 
common  and  preference  shares  of Watford  Re.  See  note  11, 
“Variable  Interest  Entity  and  Noncontrolling  Interests,”  for

16.  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 
the 
assessment  of 
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.

including,  among  others, 

factors, 

losses  and 

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 exists 
with respect to reinsurance recoverables as they may become 
uncollectible.  The  Company  manages  its  credit  risk  in  its 
reinsurance relationships by transacting with reinsurers that it 
considers financially sound and, if necessary, the Company may 
hold  collateral  in  the  form  of  funds,  trust  accounts  and/or 
irrevocable letters of credit. This collateral can be drawn on for 
amounts that remain unpaid beyond specified time periods on 
an  individual  reinsurer  basis.  In  addition,  certain  insurance 
policies written by the Company’s insurance operations feature

$68.2 million over the remaining earn-out period. To the extent 
that the adjusted book value of the CMG Entities drops below

All  of  these  leases  are  for  the  rental  of  office  space,  with 
expiration terms that range from 2019 to 2030. Rental expense, 
net of income from subleases, was approximately $27.6 million, 
$31.1  million  and  $24.2  million  for  2018,  2017  and  2016, 
respectively.

At December 31, 2018, the Company has entered into capital 
lease agreements. The future lease payments for the Company’s 
capital leases are expected to be $6.2 million, $4.8 million and 
$2.1 million for 2019, 2020 and 2021, respectively.

The Company has also entered into certain agreements which 
commit the Company to purchase goods or services, primarily 
related to software and computerized systems. Such purchase 
obligations  were  approximately  $39.5  million  and  $29.7 
million at December 31, 2018 and 2017, respectively.

Employment and Other Arrangements

At  December 31,  2018,  the  Company  has  entered  into 
employment agreements with certain of its executive officers. 
Such employment arrangements provide for compensation in 
the  form  of  base  salary,  annual  bonus,  share-based  awards, 
participation in the Company’s employee benefit programs and 
the reimbursements of expenses.

large  deductibles,  primarily  in  its  construction  and  national 
accounts lines of business. Under such contracts, the Company 
is obligated to pay the claimant for the full amount of the claim. 
The Company is subsequently reimbursed by the policyholder 
for the deductible amount. These amounts are included on a 
gross basis in the consolidated balance sheet in contractholder 
payables  and  contractholder  receivables,  respectively.  In  the 
event  that  the  Company  is  unable  to  collect  from  the 
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 records a 
related liability in “Collateral held for insured obligations.”

In addition, the Company underwrites a significant amount of 
its business through brokers and a credit risk exists should any 
of these brokers be unable to fulfill their contractual obligations 
with  respect  to  the  payments  of  insurance  and  reinsurance 
balances  owed

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 October 26, 2016, Arch Capital and certain of its subsidiaries 
entered  into  an  $850.0  million  five-year  credit  facility  (the 
“Credit  Facility”)  with  a  syndication  of  lenders.  The  Credit 
Facility consists of a $350.0 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. Subject to the receipt of commitments, the Secured 
Facility  may  be  increased  by  up  to  an  aggregate  of  $350.0 
million,  and  the  Unsecured  Facility  may  be  increased  to  an 
amount not to exceed $750.0 million. 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 LIBOR or an alternative base rate at the 
option of Arch Capital. Secured letters of credit are available 
for  issuance  on  behalf  of  Arch  Capital  insurance  and 
reinsurance subsidiaries. The Credit Facility is structured such 
that each party that requests a letter of credit or borrowing does 
so only for itself and for only its own obligations.

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, 2018.

Commitments under the Credit Facility will expire on October 
26, 2021, and all loans then outstanding must be repaid. Letters 
of credit issued under the Unsecured Facility will not have an 
expiration date later than October 26, 2022.

Under the $350.0 million secured letter of credit facility, Arch 
Capital’s  subsidiaries  had  $174.8  million  of  letters  of  credit 
outstanding  and  remaining  capacity  of  $175.2  million  at 
December 31,  2018.  In  addition,  certain  of  Arch  Capital’s 
subsidiaries had outstanding letters of credit of $167.5 million, 
which  were  issued  in  the  normal  course  of  business.  When 
issued, these letters of credit are secured by a portion of the 
investment  portfolio. At  December 31,  2018,  these  letters  of

credit were secured by investments with a fair value of $362.0 
million.

18.  Goodwill and Intangible Assets

Watford Re has access to a $100 million letter of credit facility 
expiring on May 16, 2019 and an $800 million secured credit 
facility  expiring  on  November  30,  2021,  that  provides  for 
borrowings and the issuance of letters of credit not to exceed 
$400 million. Borrowings of revolving loans may be made by 
Watford Re at a variable rate based on LIBOR or an alternative 
base rate at the option of Watford Re. At December 31, 2018, 
Watford Re had $68.9 million in outstanding letters of credit 
under  the  two  facilities  and  $455.7  million  of  borrowings 
outstanding under the secured credit facility, backed by Watford 
Re’s investment portfolio. Watford Re was in compliance with 
all  covenants  contained  in  both  of  its  credit  facilities  at 
December 31,  2018.  The  Company  does  not  guarantee  or 
provide  credit  support  for  Watford  Re,  and  the  Company’s 
financial exposure to Watford Re is limited to its investment in 
Watford Re’s common and preferred shares and counterparty 
credit risk (mitigated by collateral) arising from the reinsurance 
transactions.

The  Company’s  outstanding  revolving  credit  agreement 
borrowings were as follows:

connection with the AIG acquisition.

Three-For-One Common Share Split

In May 2018, shareholders approved a proposal to amend the 
memorandum  of  association  by  sub-dividing  the  authorized 
common shares of Arch Capital to effect a three-for-one split 
of Arch Capital’s common shares. The share split changed the 
Company’s authorized common shares to 1.8 billion common 
shares (600 million previously), with a par value of $.0011 per 
share  ($.0033  previously).  Information  pertaining  to  the 
composition of the Company’s shareholders’ equity accounts, 
shares and earnings per share has been retroactively restated in 
the  accompanying  financial  statements  and  notes  to  the 
consolidated financial statements to reflect the share split.

The estimated remaining useful lives of these assets range from 
one to eighteen years at December 31, 2018. 

Share Repurchase Program

Other  than  the  impairment  described  above,  the  Company’s 
annual impairment reviews for goodwill and intangible assets 
did not result in the recognition of impairment losses for 2018, 
2017 and 2016.

The  board  of  directors  of  Arch  Capital  has  authorized  the 
investment in Arch Capital’s common shares through a share 
repurchase  program.  At  December 31,  2018,  approximately 
$163.7 million of share repurchases were available under the 
program. Repurchases under the program may be effected from 

ARCH CAPITAL

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

time to time in open market or privately negotiated transactions 
through  December  31,  2019. 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, 
2018, Arch Capital held 168.3 million shares for an aggregate 
cost of $2.38 billion in treasury, at cost.

The  Company’s  repurchases  under  the  share  repurchase 
program were as follows:

Since the inception of the share repurchase program through

approximately 386.2 million common shares for an aggregate 
purchase price of $3.97 billion. 

Convertible  Non-Voting  Common  Equivalent  Preferred 
Shares

On December 31, 2016, the Company completed the acquisition 
of all of the outstanding shares of capital stock of UGC. Based 
upon a formula set forth in the Stock Purchase Agreement, AIG 
received 1,276,282 of Arch Capital’s Series D convertible non-
voting  common  equivalent  preferred  shares  (“Series  D 
Preferred Shares”). Each Series D Preferred Share converts to 
10 shares of Arch Capital fully paid non-assessable common 
stock. 

The  Company  determined,  based  on  a  review  of  the  terms 
features and rights of the series D preferred shares compared 
to  the  rights  of  the  Company’s  common  shareholders,  the 
underlying 38,288,460 common shares (split adjusted) that the 
convertible  securities  convert 
to  were  common  share 
equivalents at the time of their issuance. 

In June 2017, Arch Capital completed an underwritten public 
secondary  offering  of  21,265,860  common  shares  (split 
adjusted)  by  AIG  following  transfer  of  708,862  Series  D 
Preferred Shares. In March 2018, Arch Capital completed an 
underwritten public secondary offering of 17,022,600 common 
shares  (split  adjusted)  by AIG  following  transfer  of  567,420 
Series D Preferred Shares. Proceeds from the sale of common 
shares pursuant to the public offering were received by AIG. 

At  December 31,  2018,  no  Series  D  Preferred  Shares  were 
outstanding.

Series F Preferred Shares

In August 2017 and November 2017, Arch Capital completed 
combined $330 million of underwritten public offerings ($230 
million in August 2017 and $100 million in November 2017) 
of  13.2  million  depositary  shares  (the  “Series  F  Depositary 
Shares”), each of which represents a 1/1,000th interest in a share 
of its 5.45% Non-Cumulative Preferred Shares, Series F, have 
a $0.01 par value and $25,000 liquidation preference per share 
(equivalent  to  $25  liquidation  preference  per  Series  F 
Depositary  Share)  (the  “Series  F  Preferred  Shares”).  Each 
Series F 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 F 
Preferred Shares represented thereby (including any dividend, 
liquidation, redemption and voting rights). 

Holders of Series F Preferred Shares will be entitled to receive 
dividend payments only when, as and if declared by our board 
of directors 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  5.45%.  Dividends  on  the  Series  F 
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 
F Preferred Shares. 

Except  in  specified  circumstances  relating  to  certain  tax  or 
corporate  events,  the  Series  F  Preferred  Shares  are  not 
redeemable prior to August 17, 2022 (the fifth anniversary of 
the issue date). On and after that date, the Series F Preferred 
Shares will be redeemable at the Company’s option, in whole 
or in part, at a redemption price of $25,000 per share of the 
Series  F  Preferred  Shares  (equivalent  to  $25  per  depositary 
share),  plus  any  declared  and  unpaid  dividends,  without 
accumulation of any undeclared dividends to, but excluding, 
the redemption date. The Series F Depositary Shares will be 
redeemed  if  and  to  the  extent  the  related  Series  F  Preferred 
Shares  are  redeemed  by  the  Company.  Neither  the  Series  F 
Depositary  Shares  nor  the  Series  F  Preferred  Shares  have  a 
stated maturity, nor will they be subject to any sinking fund or 
mandatory redemption. The Series F Preferred Shares are not 
convertible  into  any  other  securities. The  Series  F  Preferred 
Shares  will  not  have  voting  rights,  except  under  limited 
circumstances. The net proceeds from the Series F Preferred 
Share  offerings  were  used  to  redeem  the  Company’s 
outstanding 6.75% Series C Non-Cumulative Preferred Shares.

Series E Preferred Shares

On September 29, 2016, Arch Capital completed a $450 million
underwritten public offering of 18.0 million depositary shares 

ARCH CAPITAL

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

(the “Series E Depositary Shares”), each of which represents a 
1/1,000th  interest  in  a  share  of  its  5.25%  Non-Cumulative 
Preferred Shares, Series E, have a $0.01 par value and $25,000 
liquidation preference per share (equivalent to $25 liquidation 
preference  per  Series  E  Depositary  Share)  (the  “Series  E 
Preferred Shares”). Each Series E 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 E Preferred Shares represented thereby 
(including  any  dividend,  liquidation,  redemption  and  voting 
rights).

Holders of Series E Preferred Shares will be entitled to receive 
dividend payments only when, as and if declared by our board 
of directors or a duly authorized committee of the board. Any 
such dividends will be payable from, and including, the date of 
original issue on a non-cumulative basis, quarterly in arrears 
on the last day of March, June, September and December of 
each year, at an annual rate of 5.25%. Dividends on the Series 
E 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 
E preferred shares. 

Except  in  specified  circumstances  relating  to  certain  tax  or 
corporate  events,  the  Series  E  Preferred  Shares  are  not 
redeemable prior to September 29, 2021 (the fifth anniversary 
of the issue date). On and after that date, the Series E Preferred 
Shares will be redeemable at the Company’s option, in whole 
or in part, at a redemption price of $25,000 per share of the 
Series  E  Preferred  Shares  (equivalent  to  $25  per  Series  E 
Depositary  Share),  plus  any  declared  and  unpaid  dividends, 
without  accumulation  of  any  undeclared  dividends  to,  but 
excluding, the redemption date. The Series E Depositary Shares 
will  be  redeemed  if  and  to  the  extent  the  related  Series  E 
Preferred Shares are redeemed by the Company. Neither the 
Series E Depositary Shares nor the Series E Preferred Shares 
have a stated maturity, nor will they be subject to any sinking 
fund or mandatory redemption. The Series E Preferred Shares 
are  not  convertible  into  any  other  securities.  The  Series  E 
Preferred  Shares  will  not  have  voting  rights,  except  under 
limited circumstances. 

Series C Preferred Shares

On  January  2,  2018, Arch  Capital  redeemed  all  outstanding 
6.75% Series C non-cumulative preferred shares. The preferred 
shares were redeemed at a redemption price equal to $25 per 
share, plus all declared and unpaid dividends to (but excluding) 
the redemption date. In accordance with GAAP, following the 
redemption, original issuance costs related to such shares have 
been removed from additional paid-in capital and recorded as 
a “loss on redemption of preferred shares.” Such adjustment 
had no impact on total shareholders’ equity or cash flows.

Stock Options and Stock Appreciation Rights

Restricted Common Shares and Restricted Units

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 Company also issues restricted share and unit awards to 
eligible  employees  and  directors,  for  which  the  fair  value  is 
equal  to  the  fair  market  values  of  the  Company’s  Common 
Shares  on  the  grant  dates.  Restricted  share  and  unit  awards 
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-Scholes 
option  valuation  model.  The  expected  life  assumption  was 
based  on  an  expected  term  analysis,  which  incorporated  the 
Company’s historical exercise experience. Expected volatility 
is based on the Company’s daily historical trading data of its 
common shares. The table below summarizes the assumptions 
used.

 Performance Awards

Share-Based Compensation Expense

The Company also issues performance share and unit awards 
(“performance  awards”)  to  eligible  employees,  which  are 
earned based on the achievement of pre-established threshold, 
target  and  maximum  goals  over  three-year  performance 
periods. Final payouts depend on the level of achievement along 
with each employees continued service through the vest date. 
The grant date fair value of the performance awards is measured 
using a Monte Carlo simulation model, which incorporated the 
assumptions summarized in the table below. Expected volatility 
is based on the Company’s daily historical trading data of its 
common  shares.  The  cumulative  compensation  expense 
recognized and unrecognized as of any reporting period date 
represents the adjusted estimate of performance shares and units 
that will ultimately be awarded, valued at their original grant 
date fair values.

statements and statements prepared in accordance with GAAP

The Company has two Bermuda based subsidiaries: Arch Re 
Bermuda, a Class 4 insurer and long-term insurer, and Watford 
Re, a Class 4 insurer. Under the Bermuda Insurance Act 1978 
(the  “Insurance  Act”),  these  subsidiaries  are  required  to 
maintain minimum statutory capital and surplus equal to the 
greater of a minimum solvency margin and the enhanced capital 
requirement as determined by the Bermuda Monetary Authority 
(“BMA”).  The  enhanced  capital  requirement  is  calculated 
based on the Bermuda Solvency Capital Requirement model, 
a  risk-based  model 
the  risk 
characteristics of different aspects of the company’s business. 
At December 31, 2018 and 2017, all such requirements were

that 

The  ability  of  these  subsidiaries  to  pay  dividends  is  limited 
under Bermuda law and regulations. Under the Insurance Act, 
Arch Re Bermuda is restricted with respect to the payment of 
dividends. 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 Bermuda 
Monetary Authority 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  $2.62  billion  to  Arch  Capital  during  2019 
without providing an affidavit to the BMA. 

Ireland

The Company has two Irish subsidiaries: Arch Re Europe, an 
authorized life and non-life reinsurer, and Arch MI Europe, an 
authorized  non-life  insurer.  Irish  authorized  reinsurers  and 
insurers, such as Arch Re Europe and Arch MI Europe, are also 
subject  to  the  general  body  of  Irish  laws  and  regulations 
including the provisions of the Companies Act 2014. Arch Re 
Europe and Arch MI Europe are subject to the supervision of 
the Central Bank of Ireland (“CBOI”) and must comply with 
Irish insurance acts and regulations as well as with directions 
and  guidance  issued  by  the  CBOI.  These  subsidiaries  are

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

required to maintain a minimum level of capital. At December 
31, 2018 and 2017, 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 
the 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 $123.2 million of dividends during 
2019  subject  to  the  approval  of  the  Commissioner  of  the 
Delaware Department of Insurance. 

Arch  Mortgage  Insurance  Company  and  United  Guaranty 
Residential Insurance Company have each been approved as an 
eligible  mortgage  insurer  by  Fannie  Mae  and  Freddie  Mac, 
subject to maintaining certain ongoing requirements (“eligible 
mortgage  insurers”).  In  April  2015,  the  GSEs  published 
comprehensive,  revised  requirements,  known  as  the  Private 
Mortgage Insurer Eligibility Requirements or “PMIERs.” As 
clarified and revised by the Guidance Letters issued by the GSEs 
in December 2016 and March 2017, the PMIERs apply to the 
Company’s eligible mortgage insurers, but do not apply to Arch 
Mortgage Guaranty Company, which is not GSE-approved.

The amount of assets required to satisfy the revised financial 
requirements of the PMIERs at any point in time will be affected 
by  many  factors,  including  macro-economic  conditions,  the 
size  and  composition  of  our  eligible  mortgage  insurers’ 
mortgage  insurance  portfolio  at  the  point  in  time,  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 detailed regulation by their domiciliary and primary 
regulators,  the  Wisconsin  Office  of  the  Commissioner  of 
Insurance  (“Wisconsin  OCI”)  for Arch  Mortgage  Insurance 

Company and Arch Mortgage Guaranty Company, the North 
Carolina  Department  of  Insurance  (“NC  DOI”)  for  United 
Guaranty  Residential  Insurance  Company,  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 restricted to writing a single 
type  of  insurance  business,  such  as  mortgage  insurance 
business. Each company is subject to either Wisconsin or North 
Carolina  statutory  requirements  as  to  payment  of  dividends. 
Generally, both Wisconsin and North Carolina law precludes 
any  dividend  before  giving  at  least  30  days’  notice  to  the 
Wisconsin OCI or NC DOI, as applicable, and prohibits paying 
any dividend unless it is fair and reasonable to do so. In addition, 
the state regulators and the GSEs limit or restrict our eligible 
mortgage  insurers’  ability  to  pay  stockholder  dividends  or 
otherwise return capital to shareholders. Under respective states 
law, our U.S. mortgage subsidiaries can declare a maximum of 
approximately  $324.4  million  of  dividends  during  2019.  In 
certain instances, approval by the GSEs would be required for 
dividends or other forms of return of capital to shareholders due 
to  the  requirements  under  PMIERs,  including  the  minimum 
required assets imposed on our eligible mortgage insurers by 
the GSEs. Such dividend would result in an increase in 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  both  require  a  mortgage  insurer  to  maintain  a 
“minimum  policyholder  position”  calculated  in  accordance 
with  their  respective  regulations.  Policyholders'  position 
consists primarily of statutory policyholders' surplus plus the 
statutory  contingency  reserve,  less  ceded  reinsurance. While 
the statutory contingency reserve is reported as a liability on 
the statutory balance sheet, for risk-to-capital ratio calculations, 
it is included as capital for purposes of statutory capital.

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.  The  Company’s 
European insurance operations are conducted on two platforms: 
Arch  Insurance  Company  Europe  and Arch  Syndicate  2012. 
Arch  Syndicate  2012  has  one  member,  Arch  Syndicate 
is  managed  by  Arch 
Investments  Ltd.  (“ASIL”)  and 
Underwriting at Lloyd’s Ltd (“AUAL”). All U.K. companies 
are also subject to a range of statutory provisions, including the 
laws and regulations of the Companies Acts 2006 (as amended) 
(the “U.K. Companies Acts”).

Arch  Insurance  Company  Europe  and AUAL  (on  behalf  of 
itself, Arch Syndicate 2012 and ASIL) 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. The capital requirements are calculated 
by reference to standard formulae defined in Solvency II. At 
December  31,  2018  and  2017,  our  subsidiaries  were  in 
compliance with these requirements.

As  a  corporate  member  of  Lloyd’s, ASIL  is  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 in the form of pledged 
assets 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 
respect  to  managing  agents  and  corporate  members,  Lloyd’s 
prescribes certain minimum standards relating to management 
and  control,  solvency  and  other  requirements  and  monitors 
managing agents’ compliance with such standards.

Under  U.K.  law,  all  U.K.  companies  are  restricted  from 
declaring  a  dividend  to  their  shareholders  unless  they  have 
“profits  available  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 and insurance intermediaries 
maintain certain solvency margins and may restrict the payment 
of a dividend by Arch Insurance Company Europe, AUAL and 
ASIL.

Canada

Arch Insurance Canada and the Canadian branch of Arch Re 
U.S.  (“Arch  Re  Canada”)  are  subject  to  federal,  as  well  as 
provincial and territorial, regulation in Canada. The Office of 
the  Superintendent  of  Financial  Institutions  (“OSFI”)  is  the 
federal regulatory body that, under the Insurance Companies 
Act  (Canada),  regulates  federal  Canadian  and  non-Canadian 
insurance  companies  operating  in  Canada.  Arch  Insurance 
Canada and Arch Re Canada are subject to regulation in the 
provinces and territories in which they underwrite insurance/
reinsurance,  and  the  primary  goal  of  insurance/reinsurance 
regulation at the provincial and territorial levels is to govern 
the market conduct of insurance/reinsurance companies. Arch 
Insurance Canada is licensed to carry on insurance business by 
OSFI and in each province and territory. Arch Re Canada is 
licensed to carry-on reinsurance business by OSFI and in the 
provinces of Ontario and Quebec. 

Under the Insurance Companies Act (Canada), Arch Insurance 
Canada is required to maintain an adequate amount of capital 
in Canada, calculated in accordance with a test promulgated by 
OSFI called the Minimum Capital Test (“MCT”), and Arch Re 
Canada is required to maintain an adequate margin of assets 
over liabilities in Canada, calculated in accordance with a test 
promulgated by OSFI called the Branch Adequacy of Assets 
Test. Dividends or distributions, if any, made by Arch Insurance 
Canada would result in an increase in available capital at Arch 
Insurance Company (see “—United States” section).

ITEM 9.   CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND 

FINANCIAL DISCLOSURE

Management’s Annual  Report  on  Internal  Control  Over 
Financial Reporting

is  responsible  for  establishing  and 
Our  management 
maintaining adequate internal control over 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, 2018. In 
making this assessment, management used the criteria set forth 
by the Committee of Sponsoring Organizations (COSO) of the 
Treadway  Commission 
Internal  Control-Integrated 
Framework (2013).

in 

Based on our assessment, management determined that, as of 
December 31,  2018,  our  internal  control  over  financial 
reporting was effective. The effectiveness of our internal control 
over  financial  reporting  as  of  December 31,  2018  has  been 
audited  by  PricewaterhouseCoopers  LLP,  an  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, 
2018 that have materially affected, or are reasonably likely to 
materially affect, internal control over financial reporting.

None.

ITEM 9A.  CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

In  connection  with  the  filing  of  this  Form  10-K,  our 
management, including the Chief Executive Officer and Chief 
Financial Officer, conducted an evaluation, as of December 31, 
2018, 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 because of changes 
in conditions, or the degree of compliance with the policies or 
procedures  may  deteriorate.  As  a  result  of  the  inherent 
limitations in a cost-effective control system, misstatement due 
to error or fraud may occur and not be detected. Accordingly, 
our disclosure controls and procedures are designed to provide 
reasonable, not absolute, assurance that the disclosure controls 
and procedures are met.

the President announced that the U.S. would withdraw from the 
Joint  Comprehensive  Plan  of Action  and  begin  reinstituting 
Iranian sanctions. Since May 8, 2018, our non-U.S. subsidiaries 
operating under General License H have not entered into any 
new  transactions  that  had  previously  been  permitted  under 
General License H. On June 27, 2018, OFAC revoked General 
License  H  and  added  regulations  which  authorized  all 
transactions and activities ordinarily incident and necessary to 
the  winding  down  of  activities  previously  approved  under 
General License H through November 4, 2018. Our non-U.S. 
subsidiaries operating under General License H completed their 
wind down activities by November 4, 2018, in accordance with 
all applicable laws and regulations.

ITEM 9B.  OTHER INFORMATION

Disclosure of Certain Activities Under Section 13(r) of the 
Securities Exchange Act of 1934

Section  13(r)  of  the  Securities  Exchange  Act  of  1934,  as 
amended, requires an issuer to disclose in its annual or quarterly 
reports whether it or an affiliate knowingly engaged in certain 
activities described in that section, including certain activities 
related to Iran during the period covered by the report. 

On January 16, 2016, the Office of Foreign Assets Control of 
the  U.S.  Department  of  the  Treasury  (“OFAC”)  adopted 
General License H which authorized non-U.S. entities that are 
owned  or  controlled  by  a  U.S.  person  to  engage  in  certain 
activities  with  Iran  so  long  as  they  complied  with  certain 
specific requirements set forth therein. 

As and when allowed by the applicable law and regulations, 
certain of our non-U.S. subsidiaries provide global marine and 
energy policies and global marine reinsurance which may have 
some  exposure  to  Iran.  The  global  marine  policies  and 
reinsurance provide coverage for vessels navigating into and 
out of ports worldwide. In light of European Union and U.S. 
modifications to Iran sanctions in 2016, including the issuance
