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;
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, 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;

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, 2014;
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 in our insurance or reinsurance business could cause large losses and substantial volatility in our results of operations;
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;

2



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;
losses relating to aviation business and business produced by a certain managing underwriting agency for which we may be liable to the purchaser of our prior reinsurance business or to others in connection with the May 5, 2000 asset sale described in our periodic reports filed with the SEC;
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;
statutory or regulatory developments, including as to tax policy and 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; 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.

ITEM 1. BUSINESS
As used in this report, references to “we,” “us,” “our” or the “Company” refer to the consolidated operations of Arch Capital Group Ltd. (“ACGL”) and its subsidiaries. Tabular amounts are in U.S. Dollars in thousands, except share amounts, unless otherwise noted. We refer you to Item 1A “Risk Factors” for a discussion of risk factors relating to our business.
OUR COMPANY
General
Arch Capital Group Ltd. is a Bermuda public limited liability company with $7.03 billion in capital at December 31, 2014 and, through operations in Bermuda, the United States, Europe and Canada, writes insurance and reinsurance on a worldwide basis. 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 2014, we wrote $3.62 billion of net premiums and reported net income available to Arch common shareholders of $812.4 million. Book value per common share was $45.58 at December 31, 2014, compared to $39.82 per share at December 31, 2013.
ACGL’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 Road, Pembroke HM 08, Bermuda (telephone number: (441) 278-9250). ACGL makes available free of charge through its website, located at www.archcapgroup.com, its annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and all amendments to those reports as soon as reasonably practicable after such material is electronically filed with, or furnished to, the SEC.

The public may obtain information on the operation of the Public Reference Room by calling 1-800-SEC-0330. The SEC also maintains an Internet site that contains reports, proxy and information statements, and other information regarding issuers that file electronically with the SEC (such as ACGL) and the address of that site is www.sec.gov.
Our History
Our current operations were built on an existing underwriting platform through an underwriting initiative in October 2001 to meet current and future demand in the global insurance and reinsurance markets. 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 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 January 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”). 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 November 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 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. We formed Arch Reinsurance Europe Underwriting Limited (“Arch Re Europe”), our Ireland-based reinsurance company, in 2008. In 2011, we launched treaty operations in Canada through the Canadian branch of Arch Insurance and subsequently through Arch Insurance Canada. Effective January 1, 2015, Canadian reinsurance business is written through the Canadian branch of

Arch Re U.S. (“Arch Re Canada”). We acquired the credit and surety reinsurance operations of Ariel Reinsurance Company Ltd. (“Ariel Re”) in April 2012. See “Operations—Reinsurance Operations” for further details on our reinsurance operations.
Our mortgage group includes direct mortgage insurance in the United States; mortgage reinsurance provided primarily by Arch Re Bermuda to mortgage insurers on both a proportional and non-proportional basis globally; direct mortgage insurance in Europe; and various risk-sharing products provided primarily by Arch Re Bermuda to government agencies and mortgage lenders. In 2011, we formed Arch Mortgage Insurance Limited (“Arch MI Europe”), which is authorized to underwrite mortgage insurance from its base in Ireland. On January 30, 2014, we completed the acquisition of CMG Mortgage Insurance Company from its owners, PMI Mortgage Insurance Co., in Rehabilitation (“PMI”) and CMFG Life Insurance Company (“CUNA Mutual”) and acquired PMI’s mortgage insurance platform and related assets. CMG Mortgage Insurance Company, renamed “Arch Mortgage Insurance Company” (“Arch MI U.S.”), was approved as an eligible mortgage insurer by Federal National Mortgage Association (“Fannie Mae”) and Federal Home Loan Mortgage Corporation (“Freddie Mac”), each a government sponsored enterprise (or “GSE”), and entered the U.S. mortgage insurance marketplace in 2014. Beginning in 2015, our mortgage group will also offer direct mortgage insurance in the United States through an affiliate of Arch MI U.S., Arch Mortgage Guaranty Company (“Arch Mortgage Guaranty”). See “Operations—Mortgage Operations” for further details on our mortgage operations.
On March 20, 2014, we acquired approximately 11% of Watford Holdings Ltd.’s common equity and a warrant to purchase additional common equity for $100 million. Watford Holdings Ltd. is the parent of Watford Re Ltd., a newly-formed multi-line Bermuda reinsurance company (together with Watford Holdings Ltd., “Watford Re”). Watford Re raised approximately $1.1 billion of capital. We serve as Watford Re’s reinsurance underwriting manager and Highbridge Principal Strategies, LLC (“Highbridge”), a subsidiary of JPMorgan Chase & Co., manages Watford Re’s investment assets, each under separate long term services agreements. The results of Watford Re are included in our consolidated financial statements. See “Operations—Other Operations” for further details on Watford Re.
The growth of our insurance and reinsurance platforms was supported through the net proceeds of: (1) an equity capital infusion of $763 million led by funds affiliated with Warburg Pincus LLC and Hellman & Friedman LLC in late 2001; (2) a public offering of 7.5 million of our common shares with net proceeds of $179 million in April 2002; (3) the exercise of class A warrants by our principal shareholders and other investors in September 2002, which provided net proceeds of $74 million; (4) a March 2004 public offering of 4.7 million of our common shares with net proceeds of $179 million; (5) a May 2004 public offering of $300 million principal amount of our 7.35% senior notes due May 2034; (6) a February 2006 public offering of $200 million of our 8.00% series A non-cumulative preferred shares; (7) a May 2006 public offering of $125 million of our 7.875% series B non-cumulative preferred shares; (8) an April 2012 public offering of $325 million of our 6.75% series C non-cumulative preferred shares which was used to redeem all series A and series B preferred shares; and (9) a December 2013 public offering of $500 million principal amount of 5.144% senior notes due November 1, 2043 by Arch Capital Group (U.S.) Inc. (“Arch-U.S.”), a wholly owned subsidiary of ACGL, and fully and unconditionally guaranteed by ACGL.
The board of directors of ACGL has authorized the investment in ACGL’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. Since the inception of the share repurchase program in February 2007 through December 31, 2014, ACGL has repurchased 118.1 million common shares for an aggregate purchase price of $3.24 billion. At December 31, 2014, the total remaining authorization under the share repurchase program was $887.1 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 5, “Segment Information,” of the notes accompanying our consolidated financial statements and “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of Operations.”

Insurance Operations
Our insurance operations are conducted in Bermuda, the United States, Europe, Canada, Australia and South Africa. Our insurance operations in Bermuda are conducted through Arch Insurance (Bermuda), a division of Arch Re Bermuda. In the U.S., our insurance group’s principal insurance subsidiaries are Arch Insurance, Arch Specialty, Arch Indemnity and Arch E&S.

Arch E&S, which is not currently writing business, is an approved excess and surplus lines insurer in 47 states and the District of Columbia and an admitted insurer in one state. Arch Insurance operated a branch office in Canada through January 1, 2013, at which point its operations were assumed by Arch Insurance Canada. Arch Insurance Canada is a Canada domestic company which is authorized in all Canadian provinces and territories. The headquarters for our insurance group’s U.S. support operations (excluding underwriting units) is in Jersey City, New Jersey. The insurance group has additional offices throughout the U.S., including four regional offices located in Alpharetta, Georgia, Chicago, Illinois, New York, New York and San Francisco, California. Arch Insurance Canada is headquartered in Toronto, Ontario with other regional offices in Canada.
Our insurance group’s European operations are conducted on two platforms: Arch Insurance Company Europe and Arch Syndicate 2012 (the U.K. insurance operations are collectively referred to as “Arch Insurance Europe”). Arch Insurance Europe conducts its operations from London. Arch Insurance Company Europe is approved as an excess and surplus lines insurer in 27 states and the District of Columbia and also has branches in Denmark, Germany, Italy and Spain. Arch Underwriting at Lloyd’s Ltd (“AUAL”) is the managing agent of Arch Syndicate 2012 and is responsible for the daily management of Arch Syndicate 2012. Arch Syndicate 2012 has enhanced our underwriting platform by providing us with access to Lloyd’s extensive distribution network and worldwide licenses. Arch Underwriting at Lloyd’s (Australia) Pty Ltd, based in Sydney, Australia, and Arch Underwriting Managers at Lloyd’s (South Africa) (Pty) Limited, based in Johannesburg, South Africa, are Lloyd’s services companies which underwrite exclusively for Arch Syndicate 2012.
As of February 20, 2015, our insurance group had approximately 1,240 employees.
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:
Capitalize on profitable underwriting opportunities. Our insurance group believes that its experienced management and underwriting teams are positioned to locate and identify business with attractive risk/reward characteristics. As profitable underwriting opportunities are identified, our insurance group will continue to seek to make additions to its product portfolio in order to take advantage of market trends. This may include adding underwriting and other professionals with specific expertise in specialty lines of insurance.
Centralize responsibility for underwriting. Our insurance group consists of a range of product lines. The underwriting executive in charge of each product line oversees all aspects of the underwriting product development process within such product line. Our insurance group believes that centralizing the control of such product line with the respective underwriting executive allows for close management of underwriting and creates clear accountability for results. Our U.S. insurance group has 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 observed, with responsibility for the management of each product line residing with the senior underwriting executive in charge of such product line.
Maintain a disciplined underwriting philosophy. Our insurance group’s underwriting philosophy is to generate an underwriting profit through prudent risk selection and proper pricing. Our insurance group believes that the key to this approach is adherence to uniform underwriting standards across all types of business. Our insurance group’s senior management closely monitors the underwriting process.
Focus on providing superior claims management. Our insurance group believes that claims handling is an integral component of credibility in the market for insurance products. Therefore, our insurance group believes that its ability to handle claims expeditiously and satisfactorily is a key to its success. Our insurance group

6



employs experienced claims professionals and also utilizes experienced external claims managers (third party administrators) where appropriate.
Utilize a brokerage distribution system. Our insurance group believes that by utilizing a brokerage distribution system, consisting of select international, national and regional brokers, both wholesale and retail, it can efficiently access a broad customer base while maintaining underwriting control and discipline.
Our insurance group writes business on both an admitted and non-admitted basis. Our insurance group focuses on the following areas:
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, 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: 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, 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 1,000 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

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 provide for the payment of additional commissions based on volume or profitability of business. Currently, some of our contracts with brokers provide for additional commissions based on volume. 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,” of the notes accompanying our consolidated financial statements.
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

8



maintain specific standards of established criteria for financial strength. The RSC evaluates the financial viability of its reinsurers through financial analysis, research and review of rating agencies’ reports and also monitors reinsurance recoverables and collateral with unauthorized reinsurers. The financial analysis includes ongoing qualitative and quantitative assessments of reinsurers, including a review of the financial stability, appropriate licensing, reputation, claims paying ability and underwriting philosophy of each reinsurer. Our insurance group will continue to evaluate its reinsurance requirements. See note 7, “Reinsurance,” of the notes accompanying our consolidated financial statements.
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 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. 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 and the District of Columbia and operates out of its office in Morristown, New Jersey. Our property facultative reinsurance operations are conducted primarily through Arch Re U.S. with certain executive functions conducted through Arch Re Facultative Underwriters Inc. located in Farmington, Connecticut. 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 2011, we formed Arch MI Europe, which was authorized as a non-life insurer in Ireland in December 2011. Our reinsurance operations acquired the credit and surety reinsurance operations of Ariel Re based in Zurich, Switzerland in April 2012. Treaty operations in Canada commenced in 2011 and, effective January 1, 2015, is written through Arch Re Canada, the Canadian branch of Arch Re U.S.
As of February 20, 2015, our reinsurance group had approximately 250 employees.
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 centralized control over reinsurance underwriting guidelines and authorities.
Maintain flexibility and respond to changing market conditions. Our reinsurance group’s organizational 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 and Canada, broad underwriting expertise and substantial capital facilitates 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.

9



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 non-excess motor, including U.K. business primarily emanating from one client, 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 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 on both a proportional and excess of loss basis. In addition, facultative business is written which focuses on 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;

10



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, “Commitments and Contingencies—Concentrations of Credit Risk,” of the notes accompanying our consolidated financial statements.
Risk Management and Retrocession. Our reinsurance group currently purchases a combination of per event excess of loss, per risk excess of loss and proportional retrocessional agreements. Such arrangements reduce the effect of individual or aggregate losses, 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,” of the notes accompanying our consolidated financial statements.
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.”

11



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 group includes direct mortgage insurance in the United States primarily provided by Arch MI U.S., which we acquired in January 2014; mortgage reinsurance provided primarily by Arch Re Bermuda to mortgage insurers on both a proportional and non-proportional basis globally; direct mortgage insurance in Europe provided by Arch MI Europe; and various risk-sharing products provided primarily by Arch Re Bermuda to government agencies and mortgage lenders.
Arch MI U.S., based in Walnut Creek, California, is licensed and operates in all 50 states, the District of Columbia and Puerto Rico. It has been approved as an eligible mortgage insurer by Fannie Mae and Freddie Mac, each a GSE, subject to maintaining certain ongoing requirements. Beginning in 2015, Arch Mortgage Guaranty, an affiliate of Arch MI U.S., will offer 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 is licensed in all states but its licenses in Florida and Connecticut are currently restricted to the servicing of existing business. Arch Mortgage Guaranty is not intended to insure mortgages that will be purchased by the GSEs and it is not approved by either GSE as an eligible mortgage insurer.
Arch MI Europe is licensed and authorized by the Central Bank of Ireland (“CBOI”) to operate on a pan-European basis under the European Freedom of Services Act. Arch MI Europe is headquartered in Dublin, Ireland. Arch Risk Partners Ltd. (“Arch Risk Partners”), a U.K. based, FSA authorized insurance intermediary authorized by the FSA in February 2012 with a representative office in Milan, Italy, and Arch Underwriters Europe Limited (“Arch Underwriters Europe”), an Ireland company, act on behalf of Arch MI Europe and Arch Re Bermuda in the arrangement of mortgage insurance and reinsurance.
As of February 20, 2015, our mortgage group had approximately 340 employees.
Strategy. The mortgage insurance market operates on its own 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, the mortgage insurance technology platform of Arch MI U.S. and its experienced management and operational flexibility to offer mortgage insurance, reinsurance and other risk-sharing products in the United States and around the world. Our mortgage group’s operating principles and goals are to:
Expand Arch MI U.S.’s business. Prior to the acquisition of Arch MI U.S., it was the leading provider of mortgage insurance products and services to credit unions in the U.S. and was approved by the GSEs as an eligible mortgage insurer solely for credit union customers. Our mortgage group’s strategy is to broaden Arch MI U.S.’s customer base to national and regional banks and mortgage originators, while maintaining and increasing Arch MI U.S.’s share of the mortgage insurance credit union market. In 2014, Arch MI U.S. substantially completed the build out of its sales force to serve banks and other mortgage originators, enabling it to serve all lenders nationwide.
Capitalize on profitable underwriting opportunities. Our mortgage group believes that its experienced management, analytics and underwriting teams are positioned to identify and evaluate business with attractive risk/reward 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 adherence to uniform underwriting standards 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 our 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.

Our mortgage group focuses on the following areas:
Direct mortgage insurance in the United States. Under their monoline insurance licenses, Arch MI U.S. and Arch Mortgage Guaranty may only offer private mortgage insurance covering first lien, one-to-four family residential mortgages. Nearly all of Arch MI U.S.’s mortgage insurance written provides first loss protection on loans originated by mortgage lenders and sold to the GSEs. Each GSE’s Congressional charter generally prohibits it from purchasing a mortgage where the principal balance of the mortgage is in excess of 80% of the value of the property securing the mortgage unless the excess portion of the mortgage is protected against default by lender recourse, participation or by a qualified insurer. As a result, such “high loan-to-value mortgages” purchased by Fannie Mae or Freddie Mac generally are insured with private mortgage insurance.
Mortgage insurance protects the insured lender, investor or GSE against loss in the event of a borrower’s default. If a borrower defaults on mortgage payments, private mortgage insurance reduces and may eliminate losses to the insured. Private mortgage insurance may also facilitate the sale of mortgage loans in the secondary mortgage market because of the credit enhancement it provides. Our primary U.S. mortgage insurance policies are predominantly “flow” insurance policies, which cover individual loans at the time the loan is originated. We also may enter into “bulk” insurance transactions with lenders and investors, under which we insure a portfolio of loans at or after origination for a negotiated price and terms. In the future, Arch MI U.S. or Arch Mortgage Guaranty may offer mortgage insurance on a “pool” basis. Under pool insurance, the mortgage insurer provides coverage on a group of specified loans, typically for 100% of all losses on every loan in the portfolio, subject to an agreed aggregate loss limit.
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 insurance to facilitate 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.
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 risk-sharing products. In addition to providing traditional mortgage insurance and reinsurance, we offer various risk-sharing products to government agencies and mortgage lenders. The GSEs are reducing their exposure to mortgage risk and shifting more of it to the private sector, creating opportunities for insurers like Arch. 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.
Underwriting Philosophy. Our mortgage group believes in a disciplined, analytical approach to underwriting mortgage risks by utilizing proprietary and third party models to forecast 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.

Marketing. Arch MI U.S. employs a sales force located throughout the U.S. to directly sell mortgage insurance products and services to its bank customers. Arch MI U.S. has entered into a distribution services agreement with CUNA Mutual (a former part owner of Arch MI U.S.) pursuant to which CUNA Mutual sales employees exclusively market Arch MI U.S. mortgage insurance products to credit union customers. In Europe and Bermuda, our products and services are distributed on a direct basis and through brokers. Each country represents a unique set of opportunities and challenges that require knowledge of market conditions and client needs to develop effective solutions.
Risk Management. Exposure to mortgage risk is monitored globally and managed through underwriting guidelines, reinsurance, 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. Reinsurance arrangements do not relieve our mortgage group from its primary obligations to insured parties. Reinsurance recoverables are recorded as assets, predicated on the reinsurers’ ability to meet their obligations under the reinsurance agreements. If the reinsurers are unable to satisfy their obligations under the agreements, our mortgage subsidiaries would be liable for such defaulted amounts.
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 sponsored, along with Highbridge, Watford Re, a new property and casualty reinsurer for which we perform underwriting services and Highbridge manages the investments, each under a long term services agreement. Watford Re’s strategy is to combine a diversified reinsurance business with a disciplined investment strategy comprised primarily of non-investment grade credit assets. Watford Re believes this combination will enable it to generate attractive risk-adjusted returns for its shareholders over the long term. Watford Re has its own management and board of directors and is responsible for the overall profitability of its results. John Rathgeber, previously Vice Chairman of Arch Worldwide Reinsurance Group, was named CEO of Watford Re. In addition, Marc Grandisson, Chairman and CEO of Arch Worldwide Reinsurance and Mortgage Groups, and Nicolas Papadopoulo, CEO Reinsurance Group, were appointed as two of the five members of the board of directors of Watford Re. We invested $100.0 million to acquire approximately 11% of Watford Re’s common equity and a warrant to purchase additional common equity. 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.
Employees
As of February 20, 2015, ACGL and its subsidiaries employed approximately 1,920 full-time employees.
Reserves
Reserve estimates are derived after extensive consultation with individual underwriters, 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.
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 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. 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.”

The preceding table does not present accident or policy year development data and, instead, presents an analysis of the claim development of gross and net balance sheet reserves existing at each calendar year-end in subsequent calendar years. The top line of the table shows the reserves, net of reinsurance recoverables, at the balance sheet date for each of the indicated years. This represents the estimated amounts of net losses and loss adjustment expenses arising in all prior years that are unpaid at the balance sheet date, including incurred but not reported (“IBNR”) reserves. The table also shows the re-estimated amount of the previously recorded reserves based on experience as of the end of each succeeding year. The estimate changes as more information becomes known about the frequency and severity of claims for individual years. The “cumulative redundancy (deficiency)” represents the aggregate change in the estimates over all prior years. The table also

16



shows the cumulative amounts paid as of successive years with respect to that reserve liability. In addition, the table reflects the claim development of the gross balance sheet reserves for ending reserves at December 31, 2004 through December 31, 2014.
The following table represents an analysis of losses and loss adjustment expenses and a reconciliation of the beginning and ending reserve for losses and loss adjustment expenses:

2014 amount relates to our acquisition of Arch MI U.S. while the 2012 amount relates to our acquisition of the trade credit and surety operations of Ariel Re.

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 December 31, 2014. 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 Operations.”
Unpaid and paid losses and loss adjustment expenses recoverable were approximately $1.81 billion at December 31, 2014. 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. 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 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.

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. Our fixed maturities, fixed maturities pledged under securities lending agreements and short-term investments had an average credit quality rating of “AA” from S&P and “Aa2” from Moody’s Investors Service (“Moody’s”) at December 31, 2014, compared to “AA-” from S&P and “Aa2” from Moody’s at December 31, 2013. Our investment portfolio had an average effective duration of approximately 3.34 years and 2.62 years at December 31, 2014 and 2013, respectively. At December 31, 2014, 94.4% of our fixed maturities and fixed maturities pledged under securities lending agreements were rated investment grade, compared to 92.6% at December 31, 2013.

For 2014, 2013 and 2012, set forth below is the pre-tax total return (before investment expenses) of the investment portfolio managed by Arch compared to the benchmark return against which we measured our portfolio during the year. 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 (see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—General—Financial Measures—Total Return on Investments”).

Ratings
Our ability to underwrite business is dependent upon 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 competitive positions 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 have become an increasingly important factor in establishing the competitive position of insurance and reinsurance companies. These ratings 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”) maintains a letter scale rating system ranging from “A++” (Superior) to “F” (In Liquidation). Moody’s maintains a letter scale rating from “Aaa” (Exceptional) to “NP” (Not Prime). S&P maintains a letter scale rating system ranging from “AAA” (Extremely Strong) to “R” (Under Regulatory Supervision). Fitch Ratings (“Fitch”) maintains a letter scale rating system ranging from “AAA” (Exceptionally Strong) to “C” (Distressed).
Our reinsurance subsidiaries, Arch Re U.S., Arch Re Bermuda and Arch Re Europe (S&P and Fitch only), and our principal insurance subsidiaries, Arch Insurance, Arch E&S, Arch Specialty, Arch Insurance Company Europe and Arch Insurance Canada (S&P and A.M. Best only), each currently has a financial strength rating of “A+” (the second highest out

19



of fifteen rating levels) with a stable outlook from A.M. Best, “A1” (the fifth highest out of 21 rating levels) with a stable outlook from Moody’s, “A+” (the fifth highest out of 21 rating levels) with a stable outlook from S&P, and “A+” (the fifth highest out of 24 rating levels) with a stable outlook from Fitch. A.M. Best has assigned a financial strength rating of “NR-3” (Rating Procedure Inapplicable) to Arch Indemnity, which is not writing business currently. Lloyd’s has financial strength ratings of “A” (the third highest out of fifteen rating levels) with a stable outlook from A.M. Best, “A+” with a stable outlook from S&P and “A+” with a stable outlook from Fitch. Our U.S. mortgage insurance subsidiary, Arch MI U.S., is rated “BBB+” (the eighth highest out of 21 rating levels) with a positive outlook by S&P and “Baa1” (the eighth highest out of 21 rating levels) by Moody’s with a stable outlook. Arch MI Europe is rated “A+” (the fifth highest out of 21 rating levels) with a stable outlook from S&P. Arch Mortgage Guaranty is rated “A3” (the seventh highest out of 21 rating levels) by Moody’s with a stable outlook. Watford Re currently has a financial strength rating of “A-” (the fourth highest out of fifteen rating levels) with a stable outlook from A.M. Best.
ACGL has received counterparty (issuer) credit ratings of “A-” (seventh highest out of 21 rating levels) with a stable outlook from S&P, “A3” (seventh highest out of 21 rating levels) with a stable outlook from Moody’s and “A” long term issuer rating (sixth highest out of 23 rating levels) with a stable outlook from Fitch. A counterparty credit rating provides an opinion on an issuer’s overall capacity and willingness to meet its financial commitments as they become due, but is not specific to a particular financial obligation.
The financial strength ratings assigned by rating agencies to insurance and reinsurance companies represent independent opinions of financial strength and ability to meet policyholder obligations and are not directed toward the protection of investors, nor are they recommendations to buy, hold or sell any securities. We can offer no assurances that our ratings will remain at their current levels, or that our security will be accepted by brokers and our insureds and reinsureds. A ratings downgrade or the potential for such a downgrade, or failure to obtain a necessary rating, could adversely affect both our relationships with agents, brokers, wholesalers and other distributors of our existing products and services and 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. In the event of a ratings downgrade or other triggering event, the exercise of such contract rights by our clients could have a material adverse effect on our financial condition and results of operations, as well as our ongoing business and operations. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Financial Condition, Liquidity and Capital Resources—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 have had longer-term relationships with insureds and brokers than us. 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 ACE Limited, Alleghany Corporation, Allied World Assurance Company, Ltd., American International Group, Inc., AXIS Capital Holdings Limited, Berkshire Hathaway, Inc., Chubb Corporation, CNA, Endurance Specialty Holdings Ltd., The Hartford Financial Services Group, Inc., HCC Insurance Holdings, Inc., Ironshore Inc., Liberty Mutual Insurance, Lloyd’s, Markel Insurance Company, RLI Corp., The Travelers Companies, W.R. Berkley Corp., XL Group plc and Zurich Insurance Group. In our reinsurance business, we compete with reinsurers that provide property and casualty lines of reinsurance, including ACE Limited, Alleghany Corporation, Argo International Holdings, Ltd., AXIS Capital Holdings Limited, Berkshire Hathaway, Inc., Endurance Specialty Holdings Ltd., Everest Re Group Ltd., Hannover Rückversicherung AG, Lloyd’s, Markel Global Reinsurance, Montpelier Re Holdings Ltd., Munich Re Group, PartnerRe Ltd., Platinum Underwriters Holdings, Ltd., RenaissanceRe Holdings Ltd., Swiss Reinsurance Company, Third Point Reinsurance Ltd., Validus Holdings Ltd. and XL Group plc.

In our mortgage business, we compete with six active U.S. mortgage insurers, which include the mortgage insurance subsidiaries of Essent Group Ltd., Genworth Financial Inc., MGIC Investment Corporation, NMI Holdings Inc., Radian Group Inc. and United Guaranty Corporation. 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”). The mortgage insurance industry’s business has been limited as a result of competition with the FHA, which substantially increased its market share beginning in 2008. Recent and future changes to the FHA program may impact the demand for private mortgage insurance. On our mortgage reinsurance and other risk sharing products, we have seen increased competition from other 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 credit risk is borne by private capital.
Enterprise Risk Management
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 our board of directors and board level committees and routinely discussed with business unit management. These limits are integrated into our operating guidelines and the 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. 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.”
Regulation
Bermuda Insurance Regulation
The Insurance Act 1978 of Bermuda and Related Regulations (“Insurance Act”). Arch Re Bermuda is subject to the Insurance Act, which provides that no person shall carry on any insurance business in or from within Bermuda unless registered as an insurer under the Insurance Act by the Bermuda Monetary Authority (the “BMA”), which is responsible for the day-to-day supervision of insurers. Under the Insurance Act, insurance business includes reinsurance business. We believe that we are in compliance with all applicable regulations under the Insurance Act.
The Insurance Act imposes solvency and liquidity standards and auditing and reporting requirements on Bermuda insurance companies and grants to the BMA powers to supervise, investigate and intervene in the affairs of insurance companies. Certain significant aspects of the Bermuda insurance regulatory framework are set forth below.
Classification of Insurers. The Insurance Act distinguishes between insurers carrying on long-term business, insurers carrying on general business and insurers carrying on special purpose business. There are six general business classifications (Classes 1, 2, 3, 3A, 3B and 4), five long-term business classifications (Classes A, B, C, D and E) and one classification of special purpose insurer.
As Arch Re Bermuda carries on both long-term and general business, it is required to be registered as both a long-term and as a general business insurer under the Insurance Act. Accordingly, Arch Re Bermuda is registered as a Class 4 general business insurer and as a Class C long-term insurer. Class 4 insurers are regarded as large commercial underwriters and are subject to the strictest regulation. Class C insurers are regarded as small commercial underwriters and are subject to less stringent regulation. Watford Re is registered as a Class 4 insurer and subject to similar regulation. The remainder of this section focuses on Arch Re Bermuda only.
Minimum Paid-Up Share Capital. Arch Re Bermuda is required to maintain fully paid-up share capital of $1.25 million.

21



Principal Representative and Principal Office. An insurer is required to maintain a principal office and to appoint and maintain a principal representative in Bermuda. It is the duty of the principal representative upon reaching the view that there is a likelihood of the insurer for which the principal representative acts becoming insolvent or that a reportable “event” has, to the principal representative’s knowledge, occurred or is believed to have occurred, to immediately notify the BMA and to make a report in writing to the BMA within 14 days of the prior notification setting out all the particulars of the case that are available to the principal representative.
Where there has been a significant loss which is reasonably likely to cause the insurer to fail to comply with its enhanced capital requirement (in respect of its general business, as described in more detail below), the principal representative must also furnish the BMA with a capital and solvency return reflecting an enhanced capital requirement prepared using post-loss data. The principal representative must provide this within 45 days of notifying the BMA regarding the loss.
Furthermore, where a notification has been made to the BMA regarding a material change to an insurer’s business or structure (including a merger or amalgamation), the principal representative has 30 days from the date of such notification to furnish the BMA with unaudited interim statutory financial statements in relation to such period if so requested by the BMA, together with a general business solvency certificate in respect of those statements.
Approved Independent Auditor. All insurers must appoint an independent auditor who annually audits and reports on the insurer’s financial statements prepared under generally accepted accounting principles (“GAAP”) or international financial reporting standards (“IFRS”) and statutory financial statements and the statutory financial return of the insurer, all of which, in the case of Arch Re Bermuda, are required to be filed annually with the BMA. The independent auditor must be approved by the BMA.
Approved Actuary. As a Class C insurer, Arch Re Bermuda is required to submit an annual actuary’s certificate when filing its statutory financial returns. The actuary, who is normally a qualified life actuary, must be approved by the BMA.
Approved Loss Reserve Specialist. As a Class 4 insurer, Arch Re Bermuda is required to submit an opinion of its approved loss reserve specialist with its statutory financial return in respect of its loss and loss expense provisions. The loss reserve specialist, who will normally be a qualified casualty actuary, must be approved by the BMA.
Annual Financial Statements, Annual Statutory Financial Return and Annual Capital and Solvency Return. Arch Re Bermuda must prepare annual statutory financial statements as prescribed in the Insurance Act with respect to both its general business and its long-term business. The statutory financial statements are distinct from the annual GAAP basis financial statements referred to below. The statutory financial return for a Class 4 insurer shall include a report of the approved independent auditor on the statutory financial statement of such insurer, solvency certificates, the statutory financial statements for the general business, the opinion of the loss reserve specialist and a schedule of reinsurance ceded. The statutory financial return for a Class C insurer shall include a report of the approved independent auditor on the statutory financial statements of such insurer, the statutory financial statements related to the long-term business, a declaration of the statutory ratios, the long-term business solvency certificate and a certificate from the approved actuary. Arch Re Bermuda is also required to file audited GAAP basis annual financial statements, which must be available to the public. In addition, Arch Re Bermuda is required to file a capital and solvency return in respect of its general business and long-term business. The capital and solvency return includes its relevant regulatory risk-based capital model, a schedule of fixed income investments by ratings categories, a schedule of net reserves for losses and loss expense provisions by line of business, a schedule of premiums written by line of business, a schedule of risk management and a schedule of fixed income securities, a schedule of commercial insurer’s solvency self assessment, a schedule of catastrophe risk return, a schedule of loss triangles or reconciliation of net loss reserves and a schedule of eligible capital.
Minimum Solvency Margins. Arch Re Bermuda, as a Class 4 insurer, must ensure that the value of its general business assets exceeds the amount of its general business liabilities by an amount greater than the prescribed minimum solvency margin ( and enhanced capital requirement pertaining to its general business. Accordingly, Arch Re Bermuda is required, with respect to its general business, to maintain a minimum solvency margin equal to the greatest of (i) $100 million, (ii) 50% of net premiums written (being gross premiums written less any premiums ceded by Arch Re Bermuda, but Arch Re Bermuda may not deduct more than 25% of gross premiums when computing net premiums written), (iii) 15% of net discounted aggregate losses and loss expense provisions and other insurance reserves and (iv) 25% of its enhanced capital requirement. As a long-term insurer, Arch Re Bermuda is also required, with respect to its long-term business, to maintain a minimum solvency margin equal to the greater of $500,000 or 1.5% of its assets. For the purpose of this calculation, assets

22



are defined as the total assets pertaining to its long-term business reported on the balance sheet in the relevant year less the amounts held in a segregated account.
Enhanced Capital Requirement. As a Class 4 insurer, Arch Re Bermuda is required to maintain available statutory capital and surplus pertaining to its general business at a level equal to or in excess of its enhanced capital requirement which is established by reference to either the Bermuda Solvency Capital Requirement model (“BSCR”) or an approved internal capital model. The BSCR 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 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. While not specifically referred to in the Insurance Act, the BMA has also 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 statutory 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 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. The long-term enhanced capital requirement is being phased in and shall be 50%, 75% and 100% of the calculated amount determined by the long-term BSCR model for financial years 2013, 2014 and 2015, respectively.
Eligible Capital. To enable the BMA to better assess the quality of the insurer’s capital resources, as a Class 4 insurer, Arch Re Bermuda is required to disclose the makeup of its capital in accordance with a 3-tiered capital system. Under this system, all of the insurer’s capital instruments will be classified as either basic or ancillary capital, which in turn will be classified into one of three tiers based on their “loss absorbency” characteristics. Highest quality capital will be classified Tier 1 Capital, lesser quality capital will be classified as either Tier 2 Capital or Tier 3 Capital. A minimum threshold of Tier 1 and maximum thresholds of Tier 2 and Tier 3 Capital used to support Arch Re Bermuda’s minimum solvency margin and enhanced capital requirement are specified under the rules. Tier 1, Tier 2 and Tier 3 Capital may, until January 1, 2024, include capital instruments that do not satisfy the requirement that the instrument be non-redeemable or settled only with the issuance of an instrument of equal or higher quality upon a breach, or if it would cause a breach, of the enhanced capital requirement. Where the BMA approved the use of certain instruments for capital purposes prior to the implementation of the eligible capital rules, the BMA’s consent must be obtained if such instruments are to remain eligible for use in satisfying the minimum solvency margin pertaining to its general business and its enhanced capital requirement.
Minimum Liquidity Ratio. Arch Re Bermuda is required to maintain a minimum liquidity ratio for general business equal to the value of its relevant assets at not less than 75% of the amount of its relevant liabilities. Relevant assets include cash and time deposits, quoted investments, unquoted bonds and debentures, first liens on real estate, investment income due and accrued, accounts and premiums receivable and reinsurance balances receivable. The relevant liabilities are total general business insurance reserves and total other liabilities less deferred income tax and sundry liabilities (by interpretation, those not specifically defined).
Restrictions on Dividends and Distributions. Arch Re Bermuda is prohibited from declaring or paying any dividends during any financial year if it is in breach of its enhanced capital requirement or its general business or long-term solvency margins or its minimum liquidity ratio or if the declaration or payment of such dividends would cause such a breach. If it has failed to meet its minimum solvency margins or minimum liquidity ratio on the last day of any financial year, Arch Re Bermuda will be prohibited, without the approval of the BMA, from declaring or paying any dividends during the next financial year. In addition, Arch Re Bermuda is prohibited from declaring or paying in any financial year dividends of more than 25% of its total statutory capital and surplus (as shown on its previous financial year’s statutory balance sheet) unless it files (at least seven days before payment of such dividends) with the BMA an affidavit stating that it will continue to meet the required margins.
Reduction of Capital. 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.
Long-Term Business Fund. An insurer carrying on long-term business is required to keep its accounts in respect of its long-term business separate from any accounts kept in respect of any other business. All receipts of its long-term business form part of its long-term business fund. No payment may be made directly or indirectly from an insurer’s long-term

23



business fund for any purpose other than a purpose related to the insurer’s long-term business, unless such payment can be made out of any surplus certified by the insurer’s approved actuary to be available for distribution otherwise than to policyholders. Arch Re Bermuda may not declare or pay a dividend to any person other than a policyholder unless the value of the assets in its long-term business fund, as certified by its approved actuary, exceeds the extent (as so certified) of the liabilities of the insurer’s long-term business. In addition, the amount of such dividend shall not exceed the aggregate of that excess and any other funds properly available for payment of dividends, being funds arising out of business of the insurer other than its long-term business.
Restrictions on Transfer of Business and Winding-Up. As a long-term insurer, Arch Re Bermuda may only transfer long-term business, other than long-term business that is reinsurance business, with the sanction of the applicable Bermuda court. A long-term insurer may only be wound-up or liquidated by order of the applicable Bermuda court.
Fit and Proper Controllers. The BMA maintains supervision over the controllers of all registered insurers in Bermuda. A controller includes: (i) the managing director of the registered insurer or its parent company; (ii) the chief executive of the registered insurer or of its parent company; (iii) a shareholder controller; and (iv) any person in accordance with whose directions or instructions the directors of the registered insurer or of its parent company are accustomed to act. The definition of shareholder controller is set out in the Insurance Act, but generally refers to (i) a shareholder who holds 10% or more of the shares carrying rights to vote at a shareholders’ meeting of the registered insurer or its parent company, or (ii) a shareholder who is entitled to exercise 10% or more of the voting power at any shareholders’ meeting of such registered insurer or its parent company, or (iii) a shareholder who is able to exercise significant influence over the management of the registered insurer or its parent company by virtue of its shareholding or its entitlement to exercise, or control the exercise of, the voting power at any shareholders’ meeting. A shareholder controller that owns 10% or more but less than 20% of the shares as described above is defined as a 10% shareholder controller; a shareholder controller that owns 20% or more but less than 33% of the shares as described above is defined as a 20% shareholder controller; a shareholder controller that owns 33% or more but less than 50% of the shares as described above is defined as a 33% shareholder controller; and a shareholder controller that owns 50% or more of the shares as described above is defined as a 50% shareholder controller.
Where the shares of the shareholder of a registered insurer, or the shares of its parent company, are traded on a recognized stock exchange, and such shareholder becomes a 10%, 20%, 33% or 50% shareholder controller of the insurer, that shareholder shall, within 45 days, notify the BMA in writing that such shareholder has become such a controller. Any person or entity who contravenes the Insurance Act by failing to give notice or knowingly becoming a shareholder controller before the required 45 days has elapsed is guilty of an offense and liable to a fine.
The BMA may file a notice of objection to any shareholder who has become a controller of any description where it appears that such shareholder is, or is no longer, a fit and proper shareholder to be a controller of the registered insurer. Any person who continues to be a controller of any description after having received a notice of objection shall be guilty of an offense.
Notification by Registered Person of Change of Controllers and Officers. All registered insurers are required to give written notice to the BMA of the fact that a person has become, or ceased to be, a controller or officer of the registered insurer within 45 days of becoming aware of such fact. An officer in relation to a registered insurer means a director, chief executive or senior executive performing duties of underwriting, actuarial, risk management, compliance, internal audit, finance or investment matters.
Notification of Material Changes. All registered insurers are required to give notice to the BMA of their intention to effect a material change within the meaning of the Insurance Act. For the purposes of the Insurance Act, the following changes are material: (i) the transfer or acquisition of insurance business being part of a scheme falling under section 25 of the Insurance Act or section 99 of the Companies Act; (ii) the amalgamation with or acquisition of another firm; (iii) engaging in unrelated business that is retail business, (iv) the acquisition of a controlling interest in an undertaking that is engaged in non-insurance business which offers services and products to persons who are not affiliates of the insurer, (v) outsourcing all or substantially all of the company’s actuarial, risk management and internal audit functions, (vi) outsourcing all or a material part of an insurer’s underwriting activity, (vii) the transfer other than by way of reinsurance of all or substantially all of a line of business, and (viii) the expansion into a material new line of business.
No registered insurer shall take any steps to give effect to a material change unless it has first served notice on the BMA that it intends to effect such material change and before the end of 14 days, either the BMA has notified such

24



company in writing that it has no objection to such change or that period has lapsed without the BMA having issued a notice of objection. Any insurer who fails to give the required notice or which effects a material change, or allows such material change to be effected, before the prescribed period has elapsed or after having received a notice of objection from the BMA shall be guilty of an offense.
Insurance Code of Conduct. Arch Re Bermuda is subject to the Insurance Code of Conduct (the “Insurance Code”), which establishes duties and standards which must be complied with to ensure it implements sound corporate governance, risk management and internal controls. Failure to comply with the requirements under the Insurance Code will be a factor taken into account by the BMA in determining whether an insurer is conducting its business in a sound and prudent manner as prescribed by the Insurance Act. Failure to comply with the requirements of the Insurance Code could result in the BMA exercising its powers of intervention and will be a factor in calculating the operational risk charge applicable in accordance with that insurer’s risk based capital model.
Cancellation of Insurer’s Registration. An insurer’s registration may be canceled by the BMA on certain grounds specified in the Insurance Act, including failure of the insurer to comply with its obligations under the Insurance Act or if, in the opinion of the BMA, the insurer has not been carrying on business in accordance with sound insurance principles.
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”). Pursuant to its powers under the Insurance Act, the BMA maintains a register of particulars for the Group detailing, among other things, the names and addresses of the Designated Insurer; each member company of the Group falling within the scope of supervision; the principal representative of the Group in Bermuda; other competent authorities supervising other member companies of the Group; and the Group auditors. The Designated Insurer must notify the BMA of any changes to the above details entered on the register of the Group.
As Group supervisor, the BMA performs a number of supervisory functions including (i) coordinating the gathering and dissemination of information which is of importance for the supervisory task of other competent authorities; (ii) carrying out a supervisory review and assessment of the Group; (iii) carrying out an assessment of the Group’s compliance with the rules on solvency, risk concentration, intra-Group transactions and good governance procedures; (iv) planning and coordinating, with other competent authorities, supervisory activities in respect of the Group, both as a going concern and in emergency situations; (v) coordinating any enforcement action that may need to be taken against the Group or any of its members; and (vi) planning and coordinating meetings of colleges of supervisors (consisting of insurance regulators) in order to facilitate the carrying out of the functions described above.
In carrying out its functions, the BMA makes rules for (i) assessing the financial situation and the solvency position of the Group and/or its members and (ii) regulating intra-Group transactions, risk concentration, governance procedures, risk management and regulatory reporting and disclosure.
Group Solvency and Group Supervision. The current supervision and solvency rules (together, “Group Rules”) apply to our Group so long as the BMA remains our group supervisor. The BMA has implemented and imposed many of the additional requirements described in this section as part of its efforts to gain equivalence under Solvency II. Due to the delays in the implementation of Solvency II in Europe, it is not expected that the European Commission will take a final decision on whether or not it will recognize the regime in Bermuda to be equivalent to that laid down in Solvency II until 2015, at the earliest. If the European Commission does not recognize the regime in Bermuda, this could mean that Arch Re Bermuda and its European Union-regulated affiliates may be subject to group supervision in Bermuda and the European Union, respectively. In addition, through the Group Rules, the BMA may take action which affects ACGL. A summary of the Group Rules is set forth below.
Annual Group Financial Statements. The Group is required to prepare and submit, on an annual basis, financial statements prepared in accordance with either IFRS or GAAP, together with statutory financial statements. The financial statements must be audited annually by the Group’s approved auditor who is required to prepare an auditor’s report thereon in accordance with generally accepted auditing standards. In addition, the Group must prepare statutory financial statements (which include, in statutory form, a balance sheet, an income statement, a statement of capital and surplus, and notes thereto). The Designated Insurer is required to file with the BMA the statutory financial statements and the audited GAAP financial statements for the Group with the BMA within five months from the end of the relevant financial year (unless specifically extended).

25



Annual Group Statutory Financial Return and Annual Capital and Solvency Return. The Group is required to prepare an annual statutory financial return which shall include, among other things, a report of the approved auditor (for the GAAP financial statements only), a business solvency certificate, the opinion of an actuary (exempt for 2013 filing), a capital and solvency certificate (and a declaration signed by two directors of the parent company, one of which may be the chief executive) and either the chief risk or chief financial officer of the parent company declaring that the return fairly represents the financial condition of the Group in all material respects). Both the annual statutory financial return and the capital and solvency return must be submitted to the BMA by the Designated Insurer within five months after its financial year end (unless specifically extended).
Quarterly Group Financial Statements. The Designated Insurer is required to file quarterly financial returns for the Group with the BMA on or before the last day of the months May, August and November of each year. The quarterly Group financial returns consist of (i) quarterly unaudited (consolidated) financial statements for each financial quarter (which must minimally include a balance sheet and income statement and must also be recent and not reflect a financial position that exceeds two months) and (ii) a list and details of material intra-Group transactions and risk concentrations, details surrounding all intra-Group reinsurance and retrocession arrangements and details of the top ten counterparties and any other counterparty exposures exceeding 10% of Group’s statutory capital and surplus.
Group Solvency Self Assessment (“GSSA”). The Group Rules require the board of directors of the parent company of the insurance group (the “Parent Board”) to establish solvency self assessment procedures for the group that factors in all the foreseeable reasonably material risks. Such procedures should be carried out at least annually and assess the quality and quantity of the capital required to adequately cover the risks to which the insurance group is exposed. Such procedures must also be an integral part of the group’s risk management framework and be reviewed and evaluated on a regular basis by the Parent Board. In particular, the GSSA should, among other things, demonstrate consideration of the relationship between risk management, the quality and quantity of capital resources, the impact of risk mitigation techniques and diversification and correlation effects between material risks; a description of the group’s risk appetite; be forward-looking; include appropriate stress and scenario testing and appropriately reflect all assets and liabilities, material off-balance sheet arrangements, material intra group transactions, relevant managerial practices, systems and controls and a valuation basis that is aligned with the risk characteristics and business model of the group.
Group Minimum Solvency Margin (“Group MSM”) and Group Enhanced Capital Requirement (“Group ECR”). Effective January 1, 2013, the Designated Insurer must ensure that the value of the Group’s assets exceeds the amount of the Group’s liabilities by the aggregate minimum margin of solvency of each qualifying member of the Group. A member is a qualifying member of the Group if it is subject to solvency requirements in the jurisdiction in which it is registered. Where the parent company exercises control in relation to any member of the group, the minimum margin of solvency of such member shall be its individual minimum solvency margin. Where the parent company exercises significant influence on any member of the Group, the minimum margin of solvency applicable to that member for purposes of calculating the Group MSM shall be an amount equal to the parent company’s percentage shareholding in the member multiplied by that member’s minimum margin of solvency. “Control” and “significant influence” shall be determined in accordance with either the IFRS or GAAP used to prepare the Group’s IFRS or GAAP financial statements. The Group is required to maintain available group capital and surplus at a level equal to 50% of the Group ECR and this requirement will increase by increments of 10% in each of the following five years until 100% is required in 2018. This phasing in schedule is conditioned upon the BMA making further adjustments that would be either needed or appropriate once the effective date of Solvency II capital requirements is finalized.
Group Eligible Capital. To enable the BMA to better assess the quality of the group’s capital resources, the Designated Insurer is required to disclose the makeup of the Group’s capital in accordance with a 3-tiered capital system. Under the eligible capital requirements, all of the Group’s capital instruments will be classified as either basic or ancillary capital which in turn will be classified into one of 3 tiers based on their “loss absorbency” characteristics. Highest quality capital will be classified Tier 1 Capital, lesser quality capital will be classified as either Tier 2 Capital or Tier 3 Capital. A minimum threshold of Tier 1 and maximum thresholds of Tier 2 and Tier 3 Capital used to satisfy the Group MSM and Group ECR requirements are specified under the rules. Tier 1, Tier 2 and Tier 3 Capital may, until January 1 2024, include capital instruments that do not satisfy the requirement that the instrument be non-redeemable or settled only with the issuance of an instrument of equal or higher quality upon a breach, or if redemption would cause a breach, of the Group ECR.

26



Group Governance. The Group Rules require the Parent Board to establish and effectively implement corporate governance policies and procedures, which it must be periodically review to ensure they continue to support the overall organizational strategy of the group. In particular, the Parent Board must:
ensure that operational and oversight responsibilities of the group are clearly defined and documented and that the reporting of material deficiencies and fraudulent activities are transparent and devoid of conflicts of interest;
establish systems for identifying on a risk sensitive basis those policies and procedures that must be reviewed annually and those policies and procedures that must be reviewed at other regular intervals;
establish a risk management and internal controls framework and ensure that it is assessed regularly and such assessment is reported to the Parent Board and the chief and senior executives;
establish and maintain sound accounting and financial reporting procedures and practices for the group; and
establish and keep under review group functions relating to actuarial, compliance, internal audit and risk management functions which must address certain specific requirements as set out in the Group Rules.
Designated Insurer Notification Obligations. The Designated Insurer must notify the BMA upon reaching a view that there is a likelihood of the Group or any member of the Group becoming insolvent or that a reportable “event” has, to the Designated Insurer’s knowledge, occurred or is believed to have occurred. Examples of a reportable “event” include a failure by the Group or any member of the Group to comply substantially with a requirement imposed upon it under the Group Rules relating to its solvency position, governance and risk management or supervisory reporting and disclosures; failure by the Designated Insurer to comply with a direction given to it under the Insurance Act in respect of the group or any of its members; a criminal conviction imposed upon any member of the Group whether in Bermuda or abroad; material breaches of any statutory requirements by any member of the Group located outside of Bermuda that could lead to supervisory or enforcement action by a competent authority; or a significant loss that is reasonably likely to cause the Group to be unable to comply with its Group ECR. Within 30 days of such notification to the BMA, the Designated Insurer must furnish the BMA with a written report setting out all the particulars of the case that are available to it and within 45 days it must furnish a Group capital and solvency return that reflects the Group ECR that has been prepared using post-loss data and unaudited financial statements for such period as the BMA shall require together with a declaration of solvency in respect thereof. The Designated Insurer must also notify the BMA in writing within 14 days of becoming aware that a requirement of the Group Rules conflicts with the laws of another jurisdiction where a member of the Group operates.
The following events constitute material changes that must be notified to the BMA: (i) the amalgamation with or acquisition of another firm, (ii) engaging in unrelated business that is retail business, (iii) the acquisition of a controlling interest in an undertaking that is engaged in non-insurance business which offers services and products to persons who are not affiliates, (iv) outsourcing all or substantially all of the actuarial, risk management and internal audit functions, (v) outsourcing all or a material part of underwriting activities, (vi) the transfer other than by way of reinsurance of all or substantially all of a line of business, and (vii) the expansion into a material new line of business.
The Designated Insurer is required to give written notice to the BMA of the fact that a person has become, or ceased to be, a controller or officer of the parent company of the Group within 45 days of becoming aware of such fact. An officer in relation to the parent company of the Group means a director, chief executive or senior executive performing duties of underwriting, actuarial, risk management, compliance, internal audit, finance or investment matters.
If it appears to the BMA that the Designated Insurer is in breach of any provision of the Insurance Act or the Group Rules, the BMA may give the Designated Insurer such directions as appear to the BMA to be desirable for safeguarding the interests of policyholders and potential policyholders of the Group.
BMA’s Powers of Intervention, Obtaining Information, Reports and Documents and Providing Information to other Regulatory Authorities. The BMA may, by notice in writing served on a registered person or a Designated Insurer, require the registered person or a Designated Insurer to provide such information and/or documentation as the BMA may reasonably require with respect to matters that are likely to be material to the performance of its supervisory functions under the Insurance Act. In addition, it may require such person’s auditor, underwriter, accountant or any other person with relevant professional skill to prepare a report on any aspect pertaining thereto. In the case of a report, the person so appointed shall immediately give the BMA written notice of any fact or matter of which he becomes aware or which indicates to him that any condition attaching to his registration under the Insurance Act is not or has not or may not be or may not have been fulfilled and that such matters are likely to be material to the performance of its functions under the

27



Insurance Act. If it appears to the BMA to be desirable in the interests of the clients of a registered person or relevant insurance group, the BMA may also exercise these powers in relation to subsidiaries, parent companies and other affiliates of the registered person or designated insurer.
If the BMA deems it necessary to protect the interests of the policyholders or potential policyholders of an insurer or insurance group, it may appoint one or more competent persons to investigate and report on the nature, conduct or state of the insurer’s or the insurance group’s business, or any aspect thereof, or the ownership or control of the insurer or insurance group. If the person so appointed thinks it necessary for the purposes of his investigation, he may also investigate the business of any person who is or has been at any relevant time, a member of the insurance group or of a partnership of which the person being investigated is a member. In this regard, it shall be the duty of every person who is or was a controller, officer, employee, agent, banker, auditor, accountant, barrister and attorney or insurance manager to produce to the person appointed such documentation as he may reasonably require for purposes of his investigation, and to attend and answer questions relevant to the investigation and to otherwise provide such assistance as may be necessary in connection therewith.
Where the BMA suspects that a person has failed to properly register under the Insurance Act or that a registered person or designated insurer has failed to comply with a requirement of the Insurance Act or that a person is not, or is no longer, a fit and proper person to perform functions in relation to a regulated activity, it may, by notice in writing, carry out an investigation into such person (or any other person connected thereto). In connection therewith, the BMA may require every person who is or was a controller, officer, employee, agent, banker, auditor, accountant, barrister and attorney or insurance manager to make a report and produce such documents in his care, custody and control and to attend before the BMA to answer questions relevant to the BMA’s investigation and to take such actions as the BMA may direct. The BMA may also enter any premises for the purposes of carrying out its investigation and may petition the court for a warrant if it believes a person has failed to comply with a notice served on him or there are reasonable grounds for suspecting the completeness of any information or documentation produced in response to such notice or that its directions will not be complied with or that any relevant documents would be removed, tampered with or destroyed.
The BMA has the power to assist other regulatory authorities, including foreign insurance regulatory authorities, with their investigations involving insurance and reinsurance companies in Bermuda if it is satisfied that the assistance being requested is in connection with the discharge of regulatory responsibilities and that such cooperation is in the public interest. The grounds for disclosure by the BMA to a foreign regulatory authority without consent of the insurer are limited and the Insurance Act provides for sanctions for breach of the statutory duty of confidentiality.
Certain Other Bermuda Law Considerations
ACGL and Arch Re Bermuda are incorporated in Bermuda as “exempted companies.” As a result, they are exempt from Bermuda laws restricting the percentage of share capital that may be held by non-Bermudians, but they may not participate in certain business transactions, including (i) the acquisition or holding of land in Bermuda (except that required for their business and held by way of lease or tenancy for terms of not more than 50 years) without the express authorization of the Bermuda legislature, (ii) the taking of mortgages on land in Bermuda to secure an amount in excess of $50,000 without the consent of the Minister of Finance, (iii) the acquisition of any bonds or debentures secured by any land in Bermuda, other than certain types of Bermuda government securities or (iv) the carrying on of business of any kind in Bermuda, except in furtherance of their business carried on outside Bermuda or under license granted by the Minister of Finance. While an insurer is permitted to reinsure risks undertaken by any company incorporated in Bermuda and permitted to engage in the insurance and reinsurance business, generally it is not permitted without a special license granted by the Minister of Finance to insure Bermuda domestic risks or risks of persons of, in or based in Bermuda.
ACGL and Arch Re Bermuda also need to comply with the provisions of The Bermuda Companies Act 1981, as amended (the “Companies Act”) regulating the payment of dividends and making distributions from contributed surplus. A company shall not declare or pay a dividend, or make a distribution out of contributed surplus, if there are reasonable grounds for believing that: (i) the company is, or would after the payment be, unable to pay its liabilities as they become due; or (ii) the realizable value of the company’s assets would thereby be less than its liabilities. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Financial Condition, Liquidity and Capital Resources—Liquidity and Capital Resources” and note 23, “Statutory Information,” of the notes accompanying our financial statements.

Under Bermuda law, only persons who are Bermudians, spouses of Bermudians, holders of a permanent resident’s certificate, holders of a working resident’s certificate or persons who are exempt pursuant to the Incentives for Job Makers Act 2011, as amended (“exempted persons”) may engage in gainful occupation in Bermuda without an appropriate governmental work permit. Our success may depend in part upon the continued services of key employees in Bermuda. Certain of our current key employees are not exempted persons and, as such, require specific approval to work for us in Bermuda. A work permit may be granted or extended upon showing that, after proper public advertisement, no exempted person is available who meets the minimum standards reasonably required by the employer.
U.S. Insurance Regulation
General. In common with other insurers, our U.S. based subsidiaries are subject to extensive governmental regulation and supervision in the various states and jurisdictions in which they are domiciled and licensed and/or approved to conduct business. The laws and regulations of the state of domicile have the most significant impact on operations. This regulation and supervision is designed to protect policyholders rather than investors. Generally, regulatory authorities have broad regulatory powers over such matters as licenses, standards of solvency, premium rates, policy forms, marketing practices, claims practices, investments, security deposits, methods of accounting, form and content of financial statements, reserves and provisions for unearned premiums, unpaid losses and loss adjustment expenses, reinsurance, minimum capital and surplus requirements, dividends and other distributions to shareholders, periodic examinations and annual and other report filings. In addition, transactions among affiliates, including reinsurance agreements or arrangements, as well as certain third party transactions, require prior regulatory approval from, or prior notice to and no disapproval by, the applicable regulator under certain circumstances. Certain insurance regulatory requirements are highlighted below. In addition, regulatory authorities conduct periodic financial, claims and market conduct examinations. Arch Insurance Company Europe is also subject to certain governmental regulation and supervision in the states where it writes excess and surplus lines insurance.
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. The private mortgage insurance industry is, and likely will continue to be, subject to substantial federal and state regulation, which has increased in recent years as a result of the past deterioration of the housing and mortgage markets in the U.S. Increased federal or state regulatory scrutiny could lead to new legal precedents, new regulations, new practices, or regulatory actions or investigations, which could adversely affect our financial condition and operating results.
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. This contrasts with admitted primary insurance policies and agreements, the rates and terms of which generally are regulated by state insurance regulators. As a practical matter, however, the rates charged by primary insurers do have an effect on the rates that can be charged by reinsurers.
Certain provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”), which became effective on July 21, 2011, provide that only the state in which a primary insurer is domiciled may regulate the financial statement credit for reinsurance taken by that primary insurer; other states will no longer be able to impose their own credit for reinsurance laws on primary insurers that are only licensed in such other states.
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. In general, credit for reinsurance is allowed in the following circumstances:
if the reinsurer is licensed in the state in which the primary insurer is domiciled;
if the reinsurer is an “accredited” or otherwise approved reinsurer in the state in which the primary insurer is domiciled;
in some instances, if the reinsurer (a) is domiciled in a state that is deemed to have substantially similar credit for reinsurance standards as the state in which the primary insurer is domiciled and (b) meets certain financial requirements; or

29



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.
Some states have adopted provisions of the National Association of Insurance Commissioners (“NAIC”) adopted amendments to its Credit for Reinsurance Model Law and Regulation (the “NAIC Credit for Reinsurance Model Act”) that allow full credit to U.S. ceding insurers for reinsurance ceded to qualified non-U.S. reinsurers (called “certified reinsurers”) based upon less than 100% collateralization. Under those provisions, collateral requirements may be reduced for international reinsurers meeting certain criteria as to financial strength and reliability that are domiciled in countries that are found to have strong systems of domestic insurance regulation. Applicants for “certified reinsurer” designation must agree to certain financial reporting, consent to jurisdiction and consent to provide collateral for the full amount of their assumed liabilities in specified circumstances. Arch Re Bermuda is approved in 11 states to post reduced collateral and is expected to be designated as a “certified reinsurer” in other U.S. states.
As a result of the requirements relating to the provision of credit for reinsurance, Arch Re U.S. and Arch Re Bermuda are indirectly subject to certain regulatory requirements imposed by jurisdictions in which ceding companies are domiciled.
Arch Re U.S. is licensed or is an accredited or otherwise approved reinsurer in 50 states and the District of Columbia and the province of Ontario, Canada. Arch Insurance is licensed as an insurer in 50 states, the District of Columbia, Puerto Rico, the U.S. Virgin Islands and Guam. Arch Specialty is licensed in one state and approved as an excess and surplus lines insurer in 49 states, the District of Columbia, Puerto Rico and the U.S. Virgin Islands. Arch E&S is licensed in one state and approved as an excess and surplus lines insurer in 47 states and the District of Columbia. Arch Indemnity is licensed as an insurer in 49 states and the District of Columbia. Arch Insurance Company Europe is eligible to write excess and surplus lines insurance in 50 states, the District of Columbia, the U.S. Virgin Islands, Guam, the Northern Mariana Islands and American Samoa by virtue of its listing on the NAIC International Insurers Department's Quarterly Listing of Alien Insurers pursuant to the Nonadmitted and Reinsurance Reform Act of 2010. Neither Arch Re Bermuda nor Arch Re Europe expects to become licensed, accredited or so approved in any U.S. jurisdiction.
Certain state regulatory agencies conduct investigations from time to time of insurance and reinsurance companies’ compliance with various federal and state laws. On June 25, 2013, the New York Department of Financial Services sent a letter to non-U.S. reinsurers approved to post reduced collateral (see “Regulation-U.S. Insurance Regulation- Credit for Reinsurance”), including Arch Re Bermuda, seeking information concerning such reinsurers’ compliance with the Iran Freedom and Counter-Proliferation Act of 2012. We cannot predict the effect or outcome of these investigations on the insurance or reinsurance industry, the regulatory framework, or our business, financial condition and results of operations.
Holding Company Acts. All states have enacted legislation that regulates insurance holding company systems. These regulations generally provide that each insurance company in the system is required to register with the insurance department of its state of domicile and furnish information concerning the operations of companies within the holding company system which may materially affect the operations, management or financial condition of the insurers within the system. All transactions within a holding company system affecting insurers must be fair and reasonable. 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. In addition, certain of such transactions cannot be consummated without the applicable insurance department’s prior approval, or its failure to disapprove after receiving notice. The holding company acts also prohibit any person from directly or indirectly acquiring control of a U.S. insurance company unless that person has filed an application with specified information with the insurance company’s domiciliary commissioner and has obtained the commissioner’s prior approval. Under most states’ statutes, including Delaware and Missouri (the states of domicile of Arch’s U.S. insurance subsidiaries), 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. Accordingly, any person or entity that acquires, directly or indirectly, 10% or more of the voting securities of ACGL without the prior approval of the commissioner will be in violation of these laws and may be subject to injunctive action requiring the disposition or seizure of those securities by the commissioner or prohibiting the voting of those securities, or to other actions that may be taken by the commissioner. In 2010, the NAIC 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. If and when the amendments are adopted by a particular state, the amended Insurance Holding Company System Regulatory Act and Regulation would 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

30



controlling person identifying the material risks within the insurance holding company system that could pose enterprise risk to the licensed companies. The amended Insurance Holding Company System Regulatory Act also requires any controlling person of a U.S. insurance company seeking to divest its controlling interest in the insurance company to file with the commissioner a confidential notice of the proposed divestiture at least 30 days prior to the cessation of control; after receipt of the notice, the commissioner shall determine those instances in which the parties seeking to divest or to acquire a controlling interest will be required to file for or obtain approval of the transaction. The amended Insurance Holding Company System Regulatory Act and Regulation must be adopted by the individual states for the new requirements to apply to U.S. domestic insurers and reinsurers. To date, only 38 states, including states in which our U.S.-based insurance subsidiaries are domiciled or licensed, have enacted legislation adopting the amended Insurance Holding Company System Regulatory Act in some form.
Enterprise Risk. The NAIC has increased its focus on risks within an insurer’s holding company system that may pose enterprise risk to the insurer. “Enterprise risk” is defined as any activity, circumstance, event or series of events involving one or more affiliates of an insurer that, if not remedied promptly, is likely to have a material adverse effect upon the financial condition or the liquidity of the insurer or its insurance holding company system as a whole. As noted above, in 2010, the NAIC adopted amendments to its Model Insurance Holding Company System Regulatory Act and Regulation, which include, among other amendments, a requirement for the ultimate controlling person to file an enterprise risk report annually. In 2012, the NAIC adopted the Risk Management and Own Risk and Solvency Assessment (“ORSA”) 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 impose additional internal review and regulatory filing requirements on licensed insurers and their parent companies.
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 insurance company’s state of domicile. Generally, such laws 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 regulatory approval. Such dividends or distributions may be subject to applicable withholding or other taxes. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Financial Condition, Liquidity and Capital Resources—Liquidity and Capital Resources” and note 23, “Statutory Information,” of the notes accompanying our financial statements.
Insurance Regulatory Information System Ratios. The NAIC Insurance Regulatory Information System (“IRIS”) was developed by a committee of state insurance regulators and is intended primarily to assist state insurance departments in executing their statutory mandates to oversee the financial condition of insurance companies operating in their respective states. IRIS identifies 13 industry ratios (referred to as “IRIS ratios”) and specifies “usual values” for each ratio. Departure from the usual values of the IRIS ratios can lead to inquiries from individual state insurance commissioners as to certain aspects of an insurer’s business. Certain of our U.S.-based subsidiaries generate IRIS ratios that are outside of the usual values. To date, none of these subsidiaries has received any notice of regulatory review regarding the IRIS ratios but there is no assurance that we may not be notified in the future.
Accreditation. The NAIC has instituted its Financial Regulation Accreditation Standards Program (“FRASP”) in response to federal initiatives to regulate the business of insurance. FRASP provides a set of standards designed to establish effective state regulation of the financial condition of insurance companies. Under FRASP, a state must adopt certain laws and regulations, institute required regulatory practices and procedures, and have adequate personnel to enforce such items in order to become an “accredited” state. If a state is not accredited, other states may not accept certain financial examination reports of insurers prepared solely by the regulatory agency in such unaccredited state. The respective states in which our insurance and reinsurance subsidiaries are domiciled are accredited states.
Risk-Based Capital Requirements. In order to enhance the regulation of insurer solvency, the NAIC adopted in December 1993 a formula and model law to implement risk-based capital requirements for property and casualty insurance companies. These risk-based capital requirements 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:

31



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. For equity investments in an insurance company affiliate, the risk-based capital requirements for the equity securities of such affiliate would generally be our U.S.-based subsidiaries’ proportionate share of the affiliate’s risk-based capital requirement.
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 a regulator can intervene with increasing degrees of authority over an insurer as the ratio of surplus to risk-based capital requirement decreases. The four action levels include:
insurer is required to submit a plan for corrective action;
insurer is subject to examination, analysis and specific corrective action;
regulators may place insurer under regulatory control; and
regulators are required to place insurer under regulatory control.
Each of our U.S. subsidiaries’ surplus (as calculated for statutory purposes) is above the risk-based capital thresholds that would require either company or regulatory action.
Guaranty Funds and Assigned Risk Plans. 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. Participation in state-assigned risk plans may take the form of reinsuring a portion of a pool of policies or the direct issuance of policies to insureds. The calculation of an insurer’s participation in these plans is usually based on the amount of premium for that type of coverage that was written by the insurer on a voluntary basis. Assigned risk pools tend to produce losses which result in assessments to insurers writing the same lines on a voluntary basis. Mortgage guaranty insurance, among other lines of business, is typically exempt from participation in guaranty funds and assigned risk plans.
Federal Regulation. Although state regulation is the dominant form of regulation for insurance and reinsurance business, the federal government in recent years has shown some concern over the adequacy of state regulation. It is not possible to predict the future impact of any potential federal regulations or other possible laws or regulations on our U.S. based subsidiaries’ capital and operations, and such laws or regulations could materially adversely affect their business. In addition, a number of federal laws affect and apply to the insurance industry, including various privacy laws and the economic and trade sanctions implemented by the Office of Foreign Assets Control (“OFAC”). OFAC maintains and enforces economic sanctions against certain foreign countries and groups and prohibits U.S. persons from engaging in certain transactions with certain persons or entities. OFAC has imposed civil penalties on persons, including insurance and reinsurance companies, arising from violations of its economic sanctions program.
Certain federal laws, such as the Real Estate Settlement Procedures Act of 1974 (“RESPA”) and the Homeowners Protection Act of 1998 (“HOPA”), directly impact mortgage insurers. Other federal law and regulation relating to mortgage lenders and servicers, the GSEs, the FHA and the VA may also affect mortgage insurers and the demand for private mortgage insurance. Such laws include 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.
The Dodd-Frank Wall Street Reform and Consumer Protection Act. The Dodd-Frank Act 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

32



2015 (“TRIPRA”), consults with the states regarding insurance matters and develops federal policy on aspects of international insurance matters. In addition, FIO is authorized to assist the Treasury Secretary in negotiating “covered agreements” between the U.S. and one or more foreign governments or regulatory authorities that address insurance prudential measures. Where a state law is inconsistent with a “covered agreement” and provides less favorable treatment to foreign insurers than U.S. companies, the FIO Director may preempt conflicting state law. In 2013, the FIO issued two reports relating to the insurance industry, one on modernization of the insurance regulatory system and one on the impact of Part II of the Nonadmitted and Reinsurance Reform Act of 2010. In its December 2013 report on modernization of the insurance regulatory system, the FIO recommended that federal standards and oversight for mortgage insurers be developed and implemented. In December 2014, the FIO issued a report on the vital role that the global reinsurance market plays in supporting insurance in the United States. The impact that these reports will have on the regulation of insurance, if any, is yet to be determined. The Dodd-Frank Act also created a uniform system for non-admitted insurance premium tax payments based on the home state of the policyholder and provides for single state regulation for financial solvency and credit for reinsurance as discussed above.
The Dodd-Frank Act established the Consumer Finance Protection Bureau (“CFPB”) to regulate the offering and provision of consumer financial products and services under federal law, including residential mortgages. Pursuant to the Dodd-Frank Act, the CFPB is charged with rulemaking and enforcement with respect to enumerated consumer laws, including RESPA, TILA, HOPA, the Secure and Fair Enforcement for Mortgage Licensing Act (“SAFE Act”) and FCRA. The Dodd-Frank Act also granted to the CFPB certain supervisory powers with respect to “covered persons” and “service providers,” as defined by the Act. The CFPB recently published residential mortgage servicing rules pursuant to TILA and RESPA. The CFPB has issued Civil Investigative Demands to several other mortgage insurers and in 2013 the United States District Court for the Southern District of Florida approved consent orders issued by the CFPB against five other mortgage insurers relating to captive reinsurers.
Under the Dodd-Frank Act, the CFPB is authorized to issue regulations governing a loan originator's determination that, at the time a loan is originated, the consumer has a reasonable ability to repay the loan (“ATR”). The CFPB issued final ATR regulations, effective January 2014, containing detailed requirements on how lenders must verify a borrower's ability to repay a covered mortgage loan. The Dodd-Frank Act provides for a statutory presumption that a borrower will have the ability to repay a loan if the loan has characteristics satisfying the definition of a qualified mortgage (“QM”) as contained in the CFPB’s ATR regulations. Creditors who violate the ATR rule can be liable for interest and fees paid by the borrower as well as actual and statutory damages. A borrower may assert such a violation as a defense by recoupment or set off in a foreclosure action.
Under the CFPB’s ATR rule, a loan is deemed to be a QM if it meets certain requirements, including:
the term of the mortgage is 30 years or less;
there is no negative amortization, interest only or balloon features;
the lender documents the loan in accordance with requirements;
the total “points and fees” do not exceed certain thresholds, generally 3%; and
the total debt-to-income ratio does not exceed 43%.
The QM definition provides a “safe harbor” for QM loans with annual percentage rates, or APRs, below the threshold of 150 basis points over the Average Prime Offer Rate and a “rebuttable presumption” of compliance with ATR requirements for QM loans with an APR above that threshold.
The ATR rule also provides for a second, temporary category that allows for more flexible underwriting requirements. To qualify under the temporary QM definition, a mortgage must meet the general product feature requirements and be eligible to be purchased or guaranteed by the GSEs while they remain under conservatorship, FHA, VA, the Department of Agriculture or the Rural Housing Service. This temporary QM category expires on January 10, 2021, or earlier to the extent that the conservatorship of the Federal Housing Finance Agency (“FHFA”) ends or federal agencies issue their own qualified mortgage rules. In May 2013, the FHFA directed the GSEs to limit purchases after January 10, 2014 to loans that meet certain QM criteria. The U.S. Department of Housing and Urban Development (“HUD”) proposed a separate definition of a qualified mortgage for loans insured by the FHA, which became effective on January 10, 2014. HUD’s QM definition is less restrictive than the CFPB’s definition in certain respects. To the extent that government agencies adopt

33



their own definitions of a qualified mortgage and those definitions are more favorable to lenders than those applicable to the market in which private mortgage insurers participate, our business may be adversely affected.
Under the QM Rule, mortgage insurance premiums that are payable by the consumer at or prior to consummation of the loan are includible in the calculation of points and fees unless, and to the extent that, they are less than or equal to those charged by FHA and are automatically refundable on a pro rata basis upon satisfaction of the loan. Borrower-paid single premium products, both refundable and non-refundable, may be included within the points and fees calculation under the QM Rule. Because inclusion of mortgage insurance premiums in the calculation of points and fees will reduce the capacity for other points and fees in order for lenders to comply with the QM Rule, mortgage originators may be less likely to use those mortgage insurance products. The treatment of mortgage insurance premiums as a component of the points and fees calculation, or the potential indirect impact of mortgage insurance premiums on the total points and fees, may be factors as to whether a loan is in the safe harbor, receives a rebuttable presumption of ability to repay, or receives no presumption.
Because of the QM evidentiary standard that gives presumption of compliance, we believe that most newly-originated mortgages are QMs. Our operating results could be adversely impacted if the QM regulations reduce the size of the origination market, reduce the willingness of lenders to extend low down payment credit, favor alternatives to private mortgage insurance such as government mortgage insurance programs, or change the mix of mortgage insurance business in ways that may be unfavorable to us.
The Dodd-Frank Act generally requires an issuer of an asset-backed security or initiator of an asset-backed transaction (a “securitizer”) to retain at least 5% of the risk associated with securitized mortgage loans, although in some cases the retained risk may be allocated between the securitizer and the mortgage originator. Lenders that originate loans that are sold to the GSEs while they are in conservatorship will not be required to retain risk associated with those loans. Changes in the conservatorship status of the GSEs or capital support provided to the GSEs by the U.S. government could impact the manner in which the credit risk retention rules apply to the GSEs.
This risk-retention requirement also does not apply to a mortgage loan that is a qualified residential mortgage (“QRM”), or that is insured or guaranteed by FHA or certain other federal agencies. In October 2014, federal regulators issued a risk-retention rule that generally defines a QRM as a mortgage meeting the requirements of a QM. As the risk retention rule treats all QM loans as QRMs, low down payment loans with private mortgage insurance that do not meet the requirements of the QM rule can only be securitized with a risk retention requirement, which may deter their origination and adversely affect our business.
The Dodd-Frank Act amended and expanded mortgage servicing requirements under TILA and RESPA. The CFPB published final regulations implementing these mortgage servicing requirements effective January 2014. New loss mitigation procedures include the prohibition of commencement of foreclosure by the loan holder or servicer until 120 days after the borrower's delinquency. This and other loss mitigation requirements could cause delays in default servicing, cause the servicing of mortgage loans to become more costly, and could have an adverse impact on the timely resolution of mortgage insurance claims.
The Homeowners Protection Act of 1998. HOPA provides for the automatic termination, or cancellation upon a borrower's request, of private mortgage insurance upon satisfaction of certain conditions. HOPA requires that lenders give borrowers certain notices with regard to the automatic termination or cancellation of mortgage insurance. These provisions apply to borrower-paid mortgage insurance for purchase money, refinance and construction loans secured by the borrower's principal dwelling. FHA and VA loans are not covered by HOPA. Under HOPA, automatic termination of mortgage insurance generally occurs when the mortgage is first scheduled to reach a loan-to-value of 78% of the home's original value, assuming that the borrower is current on the required mortgage payments. A borrower who has a “good payment history,” as defined by HOPA, may generally request cancellation of mortgage insurance when the loan-to-value is first scheduled to reach 80% of the home's original value or when actual payments reduce the loan balance to 80% of the home's original value.
Real Estate Settlement Procedures Act of 1974. Subject to limited exceptions, RESPA prohibits persons from giving or accepting anything of value in connection with the referral of a settlement service. Mortgage insurance generally has been considered to be a “settlement service” for purposes of RESPA. RESPA authorizes the CFPB, the Department of Justice, state attorneys general and state insurance commissioners to bring civil enforcement actions, and also provides for criminal penalties and private rights of action. In the past, a number of lawsuits have challenged the actions of private mortgage insurers under RESPA, alleging that the insurers violated the referral fee prohibition by entering into captive

34



reinsurance arrangements or providing products or services to mortgage lenders at improperly reduced prices in return for the referral of mortgage insurance, including the provision of contract underwriting services. In addition to these private lawsuits, in 2013, the United States District Court for the Southern District of Florida approved consent orders issued by the CFPB against five other private mortgage insurers relating to captive reinsurance. Under the settlements, the mortgage insurers will end the challenged practices, pay monetary penalties, and be subject to monitoring by the CFPB and required to make reports to the CFPB in order to ensure their compliance with the provisions of the orders.
Home Mortgage Disclosure Act of 1975. The Home Mortgage Disclosure Act of 1975 (“HMDA”) requires most mortgage originators to collect and report to the CFPB data relating to a mortgage loan applicant's race, nationality, gender, marital status, and census tract. Mortgage insurers are not required pursuant to law or regulation to report HMDA data, although, under the laws of several states, mortgage insurers are currently prohibited from discriminating on the basis of certain classifications. In 2014, mortgage insurers, through an industry trade group, voluntarily reported the same data on loans submitted for insurance as is required for most mortgage lenders under HMDA.
Secure and Fair Enforcement for Mortgage Licensing Act. The SAFE Act was enacted in 2008 to enhance consumer protection and reduce fraud by encouraging states to establish minimum standards for the licensing and registration of state-licensed mortgage loan originators. The SAFE Act also requires the establishment of a nationwide mortgage licensing system and registry for the residential mortgage industry. Administration and enforcement of the SAFE Act lies with the CFPB. Arch Fulfillment Operations Inc. (“AFOI”), as an entity engaged in the business of providing contract underwriting services to residential lenders, may be required to obtain certain mortgage lender licenses in order to comply with state specific SAFE Act requirements. AFOI is obtaining licenses in certain states.
Fair Credit Reporting Act. The FCRA imposes restrictions on the permissible use of credit report information. FCRA has been interpreted by some FTC staff and federal courts to require mortgage insurance companies to provide “adverse action” notices to consumers in the event an application for mortgage insurance is declined or offered at less than the best available rate for the loan program applied for on the basis of a review of the consumer's credit. Arch MI U.S. provides notices as required. Although Arch MI U.S. has not been involved, there has been class action litigation over FCRA adverse action notices involving the mortgage industry, including court-approved settlements.
Terrorism Risk Insurance Program Reauthorization Act of 2015. The Terrorism Risk Insurance Act of 2002, which was previously amended and extended by the Terrorism Risk Insurance Extension Act of 2005 and the Terrorism Risk Insurance Program Reauthorization Act of 2007, was amended and extended again by TRIPRA through December 31, 2020. TRIPRA provides a federal backstop for insurance related losses resulting from certain acts of terrorism on U.S. soil or against certain U.S. air carriers, vessels or foreign missions. Under TRIPRA, all U.S. based property and casualty insurers are required to make terrorism insurance coverage available in specified commercial property and casualty insurance lines. Under TRIPRA, the federal government will pay 85% of covered losses after after (i) aggregate industry insured losses resulting from the act of terrorism exceeds a statutorily prescribed program trigger, and (ii) an insurer’s losses exceed a deductible determined by a statutorily prescribed formula, up to a combined annual aggregate limit for the federal government and all insurers of $100 billion. The program trigger for calendar year 2015 is $100 million and will increase by $20 million per year until it becomes $200 million in 2020. Beginning January 1, 2016, the 85% federal share will decrease by 1% per year until it becomes 80% 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. An insurer’s deductible for each year is based on the insurer’s (together with those of its affiliates) direct commercial earned premiums for property and casualty insurance, excluding certain lines of business such as commercial auto, surety, professional liability and earthquake lines of business, for the prior calendar year multiplied by a specified percentage. The specified percentage for 2014 through 2020 is 20%.
Our U.S.-based property and casualty insurers, Arch Insurance, Arch Specialty, Arch E&S and Arch Indemnity, are subject to TRIPRA. TRIPRA specifically excludes reinsurance business and, accordingly, does not apply to our reinsurance operations. Our insurance group’s deductible for 2014 was approximately $257.9 million (i.e., 20.0% of direct earned premiums). Based on 2014 direct commercial earned premiums, our insurance group’s deductible for 2015 will be approximately $303.5 million (i.e., 20.0% of such direct earned premiums).
The Gramm-Leach-Bliley Act. The Gramm-Leach-Bliley Act of 1999 (“GLBA”), which implements fundamental changes in the regulation of the financial services industry in the United States, was enacted on November 12, 1999. The GLBA permits mergers that combine commercial banks, insurers and securities firms under one holding company, a “financial holding company.” Bank holding companies and other entities that qualify and elect to be treated as financial

35



holding companies may engage in activities, and acquire companies engaged in activities, that are “financial” in nature or “incidental” or “complementary” to such financial activities. Such financial activities include acting as principal, agent or broker in the underwriting and sale of life, property, casualty and other forms of insurance and annuities.
Until the passage of the GLBA, the Glass-Steagall Act of 1933 had limited the ability of banks to engage in securities-related businesses, and the Bank Holding Company Act of 1956 had restricted banks from being affiliated with insurers. Since passage of the GLBA, among other things, bank holding companies may acquire insurers, and insurance holding companies may acquire banks. The ability of banks to affiliate with insurers may affect our U.S. subsidiaries’ product lines by substantially increasing the number, size and financial strength of potential competitors.
The GLBA also imposes privacy requirements on financial institutions, including obligations to protect and safeguard consumers' nonpublic personal information and records, and limitations on the re-use of such information. Federal regulatory agencies have issued Interagency Guidelines Establishing Information Security Standards, or “Security Guidelines,” and interagency regulations regarding financial privacy, or “Privacy Rule,” implementing sections of GLBA. The Security Guidelines establish standards relating to administrative, technical, and physical safeguards to ensure the security, confidentiality, integrity, and the proper disposal of consumer information. The Privacy Rule limits a financial institution's disclosure of nonpublic personal information to unaffiliated third parties unless certain notice requirements are met and the consumer does not elect to prevent or “opt out” of the disclosure. The Privacy Rule also requires that privacy notices provided to customers and consumers describe the financial institutions' policies and practices to protect the confidentiality and security of the information. With respect to mortgage insurers, GLBA is enforced by the U.S. Federal Trade Commission, or FTC, and state insurance regulators. Many states have enacted legislation implementing GLBA and establishing information security regulation. Many states have enacted privacy and data security laws which impose compliance obligations beyond GLBA, including obligations to protect social security numbers and provide notification in the event that a security breach results in a reasonable belief that unauthorized persons may have obtained access to consumer nonpublic information.
GSE Qualified Mortgage Insurer Requirements. Pursuant to their charters, the GSEs purchase low down payment loans insured by MIs that they determine to be qualified. Fannie Mae and Freddie Mac have each published comprehensive requirements to become and remain a qualified mortgage insurer (the “Eligibility Requirements”). On July 10, 2014, the conservator of the GSEs, the FHFA, released for comment new Eligibility Requirements, known as the Private Mortgage Insurer Eligibility Requirements or “PMIERs.” The draft PMIERs include revised financial requirements for mortgage insurers that require a mortgage insurer’s available assets, which generally include only the most liquid assets of an insurer (“Available Assets”), to meet or exceed minimum required assets, which are calculated from PMIERs tables with several risk dimensions and are subject to a floor amount (“Minimum Required Assets”).
The comment period for the draft PMIERs closed in September 2014. We currently expect FHFA to publish final PMIERs in the first half of 2015 with an effective date 180 days thereafter. We expect that mortgage insurers will have up to two years after the final PMIERs are published to meet the PMIERs’ financial requirements. As set out in the draft PMIERs, a mortgage insurer that fails to certify by the effective date that it meets the PMIERs’ financial requirements will be subject, at a minimum, to a transition plan to achieve compliance within the two year period.
We estimate that Arch MI U.S.’s Available Assets exceeded its Minimum Required Assets as of December 31, 2014. Our estimate of Arch MI U.S.’s Minimum Required Assets is based upon its risk written as of December 31, 2014 as adjusted to reflect the risk ceded to its affiliate, Arch Re Bermuda, and third parties under quota share reinsurance arrangements. Under the draft PMIERs, risk transferred on a quota share basis to a non-exclusive affiliated reinsurer, such as Arch Re Bermuda, or to non-affiliated reinsurers, may generally be deducted for the purposes of calculating Minimum Required Assets (based upon the projected amount of direct risk in force ceded under a stress economic scenario). However, the draft PMIERs also require a mortgage insurer to seek guidance from the GSEs to determine the amount of ceded risk that may be deducted in calculating Minimum Required Assets. The GSEs approved Arch MI U.S.’s reinsurance arrangements in connection with their approval of Arch MI U.S. as an eligible insurer in January 2014. The GSEs have not yet provided us with guidance as to the treatment of the reinsurance arrangements under the PMIERs.
Arch MI U.S.’s Minimum Required Assets ultimately required by the final PMIERs and its Available Assets will be affected by many factors, including the content and timing of the final PMIERs, macro-economic conditions, the size and composition of Arch MI U.S.’s mortgage insurance portfolio at the applicable time of measurement, and the amount of ceded risk that may be deducted by Arch MI U.S. in its calculation of Minimum Required Assets. Primarily as a result of Arch MI U.S.’s projected insurance portfolio growth in 2015 and thereafter, we expect that we will need to contribute

36



additional capital to Arch MI U.S. during that period to satisfy existing GSE financial conditions and the final PMIERs’ financial requirements.
The draft PMIERs contain extensive requirements related to the operation of our mortgage insurance business, including imposing additional operational requirements in areas such as claim processing, loss mitigation, underwriting, quality control and reporting. The requirements in the draft PMIERs, if adopted in their current form, could require us to make changes to our business practices and incur additional costs in order to achieve and maintain compliance with the PMIERs.
Arch MI U.S. is currently approved by the GSEs as an eligible mortgage insurer. In addition to existing Eligibility Requirements applicable to all eligible mortgage insurers, the GSEs imposed conditions in connection with their approvals of Arch MI U.S. as a qualified mortgage insurer. These conditions require, among other things, that Arch MI U.S.:
maintain, through December 31, 2016, minimum capital funding of $400 million which may consist of statutory capital (policyholders’ surplus plus contingency reserves), dedicated reinsurance trust assets for any primary business reinsured and a value for purchased technology assets;
maintain minimum statutory capital (defined as policyholders’ surplus plus contingency reserves) of no less than $260 million;
maintain a risk-to-capital ratio of no greater than 18 to 1;
refrain from paying dividends to affiliates for three years commencing February 2014;
insure only (i) GSE-eligible loans, (ii) loans that are GSE-eligible, other than as related to loan amount, (iii) loans originated under a state housing finance agency program, (iv) loans that meet the requirements of a “Qualified Mortgage” under federal regulation, or (v) other loans not included in (i) through (iv) provided that such loans in aggregate not constitute more than 2% of Arch MI U.S.’s total outstanding risk in force with a coverage effective date on or after December 31, 2003;
obtain prior written approval to enter into transactions involving the issuance of insurance on other than an individual loan “flow” basis;
not enter into reinsurance or other risk share arrangements without prior written approval; and
re-domicile from Wisconsin to another state if requested by Fannie Mae.
Arch MI U.S.’s GSE approvals include additional conditions with respect to affiliate expense sharing arrangements, requirements to obtain a financial strength rating, provision of ancillary services (i.e., non-insurance) to customers, changes of ownership, and provisions regarding underwriting policies and claims processing.
In 2013, the GSEs also mandated minimum standards for mortgage insurer master policies, including standards relating to limitations of a mortgage insurer's rescission rights. In 2014, we developed and implemented a new master policy that conforms to these minimum standards.
State Insurance Regulation of Mortgage Insurers. Arch MI U.S. is subject to detailed regulation both by its domiciliary and primary regulator, the Wisconsin Office of the Commissioner of Insurance (“Wisconsin OCI”) and by state insurance departments in each state in which it is 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. Arch MI U.S. is subject to Wisconsin statutory requirements as to payment of dividends. The maximum amount of dividends that Arch MI U.S. may pay in any 12-month period without regulatory approval by the Wisconsin OCI is the lesser of adjusted statutory net income or 10% of statutory policyholders' surplus as of the preceding calendar year end. Adjusted statutory net income is defined for this purpose to be the greater of:
net income for the calendar year preceding the date of the dividend, minus realized capital gains for that calendar year; or
aggregate net income for the 3 calendar years preceding the date of the dividend, less realized capital gains for those calendar years and less dividends paid or credited and distributions made within the first 2 of the preceding 3 calendar years.

37



Generally, Wisconsin law precludes any dividend before giving at least 30 days notice to the Wisconsin OCI and prohibits paying any dividend unless it is fair and reasonable to do so. In addition to Wisconsin, the GSEs and other states limit or restrict Arch MI U.S.’s ability to pay stockholder dividends.
Mortgage insurance companies licensed in Wisconsin 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. 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 law, as well as that of 15 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 requires a mortgage insurer to maintain a “minimum policyholder position” calculated in accordance with regulations. Policyholders' position consists primarily of statutory policyholders' surplus plus the statutory contingency reserve. 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 NAIC has established a working group to make recommendations to the NAIC's Financial Condition Committee regarding changes to the NAIC’s Mortgage Guaranty Insurance Model Act. The NAIC working group has released several drafts which include proposed changes to minimum statutory capital requirements and changes to the extent to which, and period for which, mortgage insurers must establish and hold contingency reserves. If the NAIC revises the Mortgage Guaranty Insurance Model Act, some state legislatures are likely to enact and implement part or all of the revised provisions.
Mortgage insurance premium rates are also subject to review and approval by state regulators. Any increase in premium rates must be justified, generally on the basis of the insurer's loss and default experience, expenses and future trend analysis. Arch MI U.S. has approved premium rates for credit union and mortgage banking originated mortgage loans in all 50 states.
Legislative and Regulatory Proposals. From time to time various regulatory and legislative changes have been proposed in the insurance and reinsurance industry. Among the proposals that have been considered are the possible introduction of federal regulation in addition to, or in lieu of, the current system of state regulation of insurers and the NAIC. In addition, there are a variety of proposals being considered by various state legislatures. Two ongoing areas of work at the NAIC are model rules relating to corporate governance and consideration of enhanced methods of group supervision.
Since the GSEs were placed into the conservatorship of FHFA in 2008, there has been debate regarding the roles of the GSEs, the federal government and private capital in the U.S. housing finance system. The federal government currently plays a dominant role in the U.S. housing finance system through the GSEs and the FHA, VA and Ginnie Mae. There is broad policy consensus on the need for private capital to play a larger role and government credit risk to be reduced. However, to date there has been a lack of consensus with regard to the specific changes necessary to return a larger role for private capital and reduce the role of government. The size, complexity and centrality of the GSEs to the current housing finance system and the importance of housing to the economy make the transition to any new housing finance system difficult.
GSE and secondary market reform proposals put forward since 2008 include the nearly complete privatization and elimination of the role of the GSEs, recapitalization of the GSEs, and a number of alternatives that combine a federal role with private capital, some of which eliminate the GSEs and others of which envision an on-going role for the GSES. In February 2011, the U.S. Department of the Treasury released a proposal to reform the U.S. housing finance market. While Treasury's proposal did not provide a particular timeline for GSE reform, it included the substantial reduction of government's footprint in housing finance. With respect to long-term reform, Treasury's proposal outlined three options for a future housing finance system, each of which differs in both the structure and scale of the federal government's future role:
Option 1: Privatized system of housing finance with the federal government's role limited to providing assistance for narrowly targeted groups of borrowers, leaving the vast majority of the mortgage market to the private sector;

38



Option 2: Similar to Option 1, but with the ability for the federal government to scale up to a larger share of the market if private capital withdraws in times of financial stress; and
Option 3: Similar to Option 2, but with assistance to low- and moderate-income borrowers and with the federal government providing catastrophic reinsurance behind private capital for securities of a targeted range of mortgages.
In August 2013, the Obama Administration issued a set of core principles for housing finance reform which endorsed Option 3 and intended to ensure widespread and consistent access to 30-year fixed rate mortgages while phasing out the role of the GSEs in the housing finance system. The Obama Administration also endorsed intermediate steps to transition to a new housing finance system, including reducing the government's credit risk exposure at the GSEs through: (i) a capital markets approach in which private investors take on the risk of the portfolio's first losses, and (ii) an insurance approach in which well capitalized and regulated private institutions insure a portfolio of mortgages against default and collect insurance premiums. In January 2015, the Obama Administration called for Congress to “wind down” the GSEs.
Several reform proposals have been considered by Congress. On July 24, 2013, the House Financial Services Committee passed H.R. 2767, “The Protecting American Taxpayers and Homeowners Act of 2013” (the “PATH Act”), a comprehensive secondary market reform plan similar to Option 1 including a very limited risk-bearing role for government and winding down of the GSEs. On May 15, 2014, the Senate Banking Committee passed S. 1217, “The Housing Finance Reform and Taxpayer Protection Act of 2014” (the “Reform Bill”). The Reform Bill would create a general structure for comprehensive reform and transition, including the wind down of the GSEs and the creation of a new entity, the Federal Mortgage Insurance Corporation, or “FMIC.” Under the Reform Bill, private investors in single-family covered securities would be required to hold a 10% first loss position before FMIC, in exchange for a fee, would insure the payment of principal and interest on the covered securities. While the bill explicitly provides a role for mortgage insurance on low down-payment loans, it does not recognize the loss protection provided by mortgage insurance toward the 10% first loss requirement. FMIC would be responsible for promulgating standards for the approval and supervision of mortgage insurers, guarantors, aggregators and servicers.
The prospects for passage of housing finance and GSE reform legislation remain uncertain in both the House and Senate. New federal legislation could reduce the level of private mortgage insurance coverage used by the GSEs as credit enhancement, eliminate the GSE charter requirement altogether or otherwise alter or eliminate the role of the GSEs, and thereby materially affect Arch MI U.S.’s ability to compete and the demand for its products.
As the regulator and conservator of the GSEs, FHFA has the authority to establish the priorities of the GSEs and to control and direct their operations. FHFA has made changes to the business and operations of the GSEs, in part under the direction of annual FHFA-developed strategic plans or scorecards for the conservatorship of the GSEs. The 2014 strategic plan called for the contraction of the role of the GSEs and expansion of the role of private capital through a number of actions, including shrinking the portfolios of the GSEs, and consideration of expanded use of credit risk sharing with private market participants. FHFA’s 2015 scorecard continues these priorities.
Arch MI U.S. competes with the single-family mortgage insurance programs of FHA, which is part of HUD. In January 2015, FHA reduced the annual mortgage insurance premium it charges from 1.35% of the loan amount to 0.85%. This premium reduction will make private mortgage insurance less competitive with the FHA for borrowers with certain credit characteristics. Congress is considering legislation to reform FHA. In July 2013, the House Financial Services Committee passed the PATH Act, which contains extensive reforms to FHA, and the Senate Banking Committee passed “The FHA Solvency Act of 2013.” Despite areas of similarity, there are significant differences between the House and Senate proposed reforms. The prospects for passage of FHA reform legislation in either the House or Senate, and how differences in proposed reforms between the House and Senate might be resolved in any final legislation, are uncertain. If FHA reform were to raise FHA premiums, tighten FHA credit guidelines, make other changes which make lender use of the FHA less attractive, or implement credit risk sharing between the FHA and private mortgage insurers, these changes may be beneficial to Arch MI U.S. However, there can be no assurance that any FHA reform legislation will be enacted into law, and what provisions may be contained in any final legislation, if any.
We are unable to predict whether any of these proposed laws and regulations will be adopted, the form in which any such laws and regulations would be adopted, or the effect, if any, these developments would have on our operations and financial condition. See “—U.S. Insurance Regulation—General.”

Basel III. In 1988, the Basel Committee on Banking Supervision developed the Basel Capital Accord (“Basel I”), which set out international benchmarks for assessing banks' capital adequacy requirements. In 2005, the Basel Committee issued an update to Basel I (“Basel II”), which, among other things, governs the capital treatment of mortgage insurance purchased by domestic and international banks in respect of their origination and securitization activities. In 2013, Federal banking agencies approved new capital regulations implementing in the United States the Basel III international agreement on capital standards. These regulations include an “Advanced Approach” which is only applicable to the very largest banking organizations and other financial companies determined to be “systemically important.” The final regulations also included a simpler framework for smaller banking companies called the “Standardized Approach.” The Standardized Approach is generally applicable to banking companies with less than $250 billion in assets. The Basel III regulations restrict the instruments that can count toward meeting the capital requirements, thereby placing greater emphasis on common equity and retained earnings.
The Advanced Approach framework utilizes models to determine the capital requirements for covered entities. Pursuant to these models, covered companies will determine for each type of mortgage held in portfolio such factors as the probability of default, the loss to the bank in the event of a default, and the bank’s exposure at default. The data must be based on highly stressed economic conditions. The existence of mortgage insurance may be factored into these models, and may result in a lower capital requirement for certain classes of mortgage loans. However, the degree to which mortgage insurance will reduce capital requirements depends on the characteristics of the loans and regulatory approval of the methodology used by the banking companies. Therefore, the full extent to which mortgage insurance will reduce capital requirements under this approach is uncertain.
Under the Standardized Approach, the capital treatment of mortgage loans is essentially unchanged from Basel II. Prudently underwritten first mortgage loans will continue to generally receive a risk weight of 50%. The existence of mortgage insurance will compensate for an original loan-to-value ratio of less than 90%. If a mortgage is originated with a loan-to-value ratio that is greater than 90%, it will not be considered to be prudently underwritten unless the loan is protected by mortgage insurance or other credit support, such as readily marketable collateral.
In December, 2014, the Basel committee issued a new proposal to make further revisions in the Basel III capital rules. Among other things, the new proposal would introduce a table of risk weights for residential mortgages ranging from 25% to 100% based on the loan-to-value ratio. Comments are due on this proposal by March 27, 2015. It is possible that adoption of this proposal, and its implementation in the United States, could have an adverse impact on the mortgage insurance business. We cannot predict what impact the Basel III regulations, as approved in 2013 or as may be amended, will have on the demand for mortgage insurance.
Under both the Advanced and Standardized Approaches, the risk weight for mortgage servicing assets held by banks is sharply increased, and mortgage servicing assets above certain levels must be deducted from capital. Since a significant percentage of the mortgages insured by the mortgage insurance industry are serviced by banks or bank-owned mortgage companies, these changes could cause shifts in the amounts of mortgages serviced by banks and bank affiliates or subsidiaries relative to non-banking organizations. It is difficult to predict the impact these shifts may have on the quality of the servicing of insured mortgages or the ultimate impact on the mortgage insurance industry.
In addition to new capital standards, the Basel III international accord also calls upon the international banking regulators to impose minimum liquidity requirements on banking institutions. In September 2014, Federal banking agencies finalized a regulation implementing this new Basel III liquidity requirement by prescribing a “liquidity coverage ratio” or “LCR.” The LCR will be phased-in over a two year period that began on January 1, 2015.
The LCR requires covered banking organizations (those with $50 billion or more in assets) to maintain sufficient amounts of high quality liquid assets to withstand a specified run on the institution during a period of severe economic stress. Mortgages and mortgage-related securities are not considered to be high quality liquid assets under this test. Therefore, covered banks may decide to reduce their mortgage loan portfolios in order to replace these assets with investments that meet the definition of high quality liquid assets. We cannot predict what, if any, effect this may have on the demand for mortgage insurance.
United Kingdom Insurance Regulation
General. The Financial Services Authority (the “FSA”), which on April 1, 2013 was replaced by the Prudential Regulation Authority (“PRA”) and the Financial Conduct Authority (“FCA”), regulated insurance and reinsurance

40



companies and firms carrying on insurance mediation activities operating in the U.K. under the Financial Services and Markets Act 2000 (the “FSMA”). In May 2004, Arch Insurance Company Europe was licensed and authorized by the FSA. It holds 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 FSA and the Lloyd’s Franchise Board. AUAL 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. Arch Risk Partners was licensed and authorized by the FSA in February 2012 to conduct insurance mediation activities. 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 were assessed by the PRA during 2014. Arch Insurance Company Europe and AUAL are subject to regulation by both the PRA and FCA. Arch Risk Partners is subject to regulation by the FCA only.
Lloyd’s Supervision. The operations of AUAL and related Arch Syndicate 2012 and its corporate member, Arch Syndicate Investments Ltd (“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. Arch Insurance Company Europe and AUAL (on behalf of itself, Arch Syndicate 2012 and ASIL) are each required to demonstrate the adequacy of its financial assets to the PRA, while Arch Risk Partners is required to demonstrate the adequacy of its financial assets to the FCA. On a periodic basis, Arch Insurance Europe is required to provide the PRA and Lloyd’s with its own risk-based assessment of its capital needs, taking into account comprehensive risk factors, including market, credit, operational, liquidity and group risks to generate a revised calculation of its expected liabilities which, in turn, enable the PRA and Lloyd’s to provide individual capital guidance and requirements to Arch Insurance Europe. Arch Insurance Europe’s surplus is above the risk-based capital threshold allowed by the PRA's individual capital assessment of Arch Insurance Europe. The PRA requires that Arch Insurance Europe maintain a margin of solvency calculation based on the classes of business for which it is authorized and within its premium income projections applied to its worldwide general business.
Reporting Requirements. Like all U.K. companies, Arch Insurance Europe and Arch Risk Partners must file and submit their annual audited financial statements in accordance with IFRS and related reports to the Registrar of Companies under the U.K. Companies Act together with an annual return of certain core corporate information and changes from the prior year. This requirement is in addition to the regulatory returns required to be filed annually with the PRA or the FSA (as applicable) for Arch Insurance Company Europe, AUAL and Arch Risk Partners and, in the case of AUAL and ASIL, Lloyd’s.
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 and/or Arch Risk Partners could be required to pay levies to the FSCS.

Restrictions on Acquisition of Control. Under FSMA, the prior consent of the FSA was required, and now 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, AUAL and Arch Risk Partners, or over the parent undertaking of any regulated company. Therefore, the FSA’s prior consent was required, and now the PRA's or FCA's prior consent, as applicable, is required before any person can become a controller of ACGL. 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% (20%, in the case of an intermediary such as Arch Risk Partners) or more of the shares or voting power in the relevant company or its parent undertaking.
Restrictions on Payment of Dividends. Under English law, all companies are restricted from declaring a dividend to their shareholders unless 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 FSA required, and now 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, ASIL or Arch Risk Partners. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Financial Condition, Liquidity and Capital Resources— Liquidity and Capital Resources” and note 23, “Statutory Information,” of the notes accompanying our financial statements.
European Union Considerations. Through their respective authorizations in the U.K., a Member State of the European Union (“EU”), Arch Insurance Company Europe’s, AUAL’s and Arch Risk Partners’ authorizations are recognized throughout the European Economic Area (“EEA”), subject only to certain notification and application requirements. This authorization enables Arch Insurance Company Europe, AUAL and Arch Risk Partners 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 framework for the establishment of branches in Member States of the EU other than the U.K. was generally set forth, and remains subject to, directives adopted by the European Council, the legislative body of the EU, which directives are then implemented in each Member State. Arch Insurance Company Europe currently has branches in Denmark, Germany, Italy, Spain and Sweden and may establish branches in other Member States of the EU in the future. Further, through its authorizations in an EU Member State, Arch Risk Partners, 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.
In November 2009, the EU adopted a new directive directed at insurance and reinsurance companies known as Solvency II, which has been subject to numerous delays and must now be transposed into the national law of each Member State by March 31, 2015 and implemented by firms by January 1, 2016. Arch Insurance Company Europe, AUAL and Syndicate 2012 will be required to comply with Solvency II requirements. See “European Union Insurance and Reinsurance Regulation” below for additional details.
Canada Insurance Regulation
Arch Insurance Canada, which commenced underwriting on January 1, 2013 and Arch Re Canada, which commenced underwriting on January 1, 2015, 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/reinsurance companies operating in Canada. The primary goal of OSFI is to supervise the safety and soundness of insurance/reinsurance companies with the aim of securing the appropriate level of protection of insureds by imposing risk management, solvency and capital requirements on such companies. 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 province of Ontario.
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

42



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. Arch Insurance Canada and Arch Re Canada are required to file financial information with OSFI on an ongoing basis, including annual audited financial statements in accordance with IFRS. The appointed actuary of our Canadian operations must report annually on the adequacy of their reserves. OSFI’s continuing supervision includes analysis of this information and periodic examinations of Arch Insurance Canada and Arch Re Canada. OSFI has implemented a risk-based methodology for assessing 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.
Ireland Insurance and Reinsurance Regulation
General. The Central Bank of Ireland (“CBOI”) regulates insurance and reinsurance companies and intermediaries authorized in Ireland. We have three Irish operating subsidiaries: 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. Under the regulatory and legislative framework that applies to insurers and reinsurers, Arch Re Europe and Arch MI Europe are obliged to maintain capital reserves, to employ fit and proper personnel, and to comply with governance requirements. As an intermediary, Arch Underwriters Europe is subject to a different regulatory regime and is not subject to capital reserving 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 Acts 1963-2013.
Financial Resources. Both Arch Re Europe and Arch MI Europe are required to maintain reserves, particularly in respect of underwriting liabilities and a solvency margin as provided for in the Irish insurance acts and regulations mentioned above. Arch Re Europe must maintain assets constituting statutory reserves which must comply with principles including obligations to secure sufficiency, liquidity, security, quality, profitability and currency matching of investments. An appointed actuary must opine on the adequacy of the statutory reserves of both Arch Re Europe and Arch MI Europe annually.
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 to exercise a significant influence over the management of the undertaking.
Reporting Requirements. Like most Irish companies, Arch Re Europe, Arch MI Europe and Arch Underwriters Europe must file and submit their annual audited financial statements in accordance with Irish generally accepted accounting principles and related reports to the Registrar of Companies (“Registrar”) under the Companies Acts 1963-2013 together with an annual return of certain core corporate information. Changes to core corporate information during the year must also be notified to the Registrar. These requirements are in addition to the regulatory returns required to be filed annually with the CBOI.
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. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Financial Condition, Liquidity and Capital Resources—Liquidity and Capital Resources” and note 23, “Statutory Information,” of the notes accompanying our financial statements.
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

43



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 Europe has a branch in Denmark, Arch Re Accident & Health ApS (“Arch Re Denmark”), which is an underwriting agency underwriting accident and health business for Arch Re Europe. Arch Re Europe also has a branch in the U.K., which underwrites non-life reinsurance risk for Arch Re Europe. Finally, Arch Re Europe also has a branch outside the EEA, Arch Reinsurance Europe Underwriting Limited, 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 has not yet availed of any permit to provide services in an EEA Member State outside Ireland.
In November 2009, the EU adopted a new directive directed at insurance and reinsurance companies known as Solvency II, which has been subject to numerous delays and must now be transposed into the national law of each Member State by March 31, 2015 and implemented by firms by January 1, 2016. Arch Re Europe, Arch MI Europe and Arch Underwriters Europe will be required to comply with Solvency II requirements. See “-European Union Insurance and Reinsurance Regulation” below for additional details.
Switzerland Reinsurance Regulation
In November 2006, Arch Re Bermuda opened Arch Reinsurance Ltd., Hamilton (Bermuda), European Branch Zurich (“Arch Re Bermuda Swiss Branch”). In December 2008, Arch Re Europe opened Arch Re Europe Swiss Branch as a branch office. Upon the opening of this branch in the fourth quarter of 2008, the operations of Arch Re Bermuda Swiss Branch were transferred to Arch Re Europe Swiss Branch. Arch Re Bermuda Swiss Branch was formally de-registered from the commercial register of the Canton of Zurich in early 2009. As both Arch Re Europe and Arch Re Bermuda are domiciled outside of Switzerland and their activities were and are limited to reinsurance, their respective branches in Switzerland were and are not required to be licensed by the Swiss insurance regulatory authorities.
European Union Insurance and Reinsurance Regulation
Insurance. On November 25, 2009, the EU adopted a new directive directed at insurance and reinsurance companies known as Solvency II. Solvency II is a new regulatory regime which will impose economic risk-based solvency requirements across all EU Member States and consists of three pillars: (1) Pillar I-quantitative capital requirements, based on a valuation of the entire balance sheet; (2) Pillar II-qualitative regulatory review, which includes governance, internal controls, enterprise risk management and supervisory review process; and (3) Pillar III-market discipline, which is accomplished through reporting of the insurer’s financial condition to regulators and the public. Solvency II has been the subject of a number of delays in its implementation, and two “quick-fix” directives each pushed the implementation date back from an original implementation date of November 1, 2012. The most recent directive that amends Solvency II, the Omnibus II directive (Directive 2014/51/EU), was published and came into force in May 2014. Solvency II must now be transposed into the national law of each Member State by March 31, 2015 and implemented by firms by January 1, 2016. The detail of the Solvency II project will be set out in “delegated acts” and binding technical standards which will be issued by the European Commission and will be legally binding. A delegated act, which sets out more detailed requirements for individual insurance undertakings as well as for groups based on the overarching provisions of Solvency II and which will make up the core of the single prudential rulebook for insurance and reinsurance undertakings in the EU, was published by the European Commission on October 10, 2014 and came into force on January 18, 2015 (the “Delegated Act”).
Reinsurance. The single system established in the EU for regulation and supervision of the general insurance sector and its single passport regime had until 2007 applied only to direct insurance, and there was no common regulation of reinsurance in the EU. However, direct insurers established in a Member State of the EEA who were also authorized by their domestic regulatory authorities to transact reinsurance have had freedom to establish branches in and provide insurance services to all EEA states and that freedom has in practice been extended to their reinsurance activities. In December 2005, the EU published the Reinsurance Directive (the “Directive”) as a first step in harmonization of reinsurance regulation in the single market. Member States of the EU and the EEA were required to implement the Directive by December 2007. Pure reinsurers established in a Member State of the EU now have freedom to establish branches in and provide services to all EEA states under a regime comparable to that enjoyed by direct insurers, and they will be subject to similar rules in relation to licensing and financial supervision.

44



Arch Insurance Company Europe, AUAL and Arch Risk Partners, being established in the U.K. and authorized 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. Arch Re Europe, being established in Ireland and authorized by the CBOI to write reinsurance, is 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 in those EEA states which have implemented the Directive. The Directive itself 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 particular Member States, 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. Unless agreement is reached between the European Commission and Bermuda to accord Bermuda based reinsurers with market access on the basis of the equivalent nature of Bermuda regulation, each individual EEA Member State may impose conditions on reinsurance provided by Bermuda based reinsurers which could restrict their future provision of reinsurance to the EEA Member State concerned. A number of EEA Member States currently restrict the extent to which Bermudian reinsurers may promote their services in those Member States, and a few have certain prohibitions on the purchase of insurance from reinsurers not authorized in the EEA. The Directive is scheduled to be repealed and replaced by new provisions under Solvency II on January 1, 2016. However, this may change depending on whether the implementation date for Solvency II is extended again from January 1, 2016.
Article 172 of Solvency II will, when it comes into force, provide 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. The European Commission is considering whether the solvency regime in Bermuda is equivalent to that laid down in Solvency II. In October 2011, the European Insurance and Occupational Pension Authority (“EIOPA”), which is established under European Law as an independent advisory body to the European Parliament, the European Council and the European Commission and specifically to assist in preparing equivalence decisions, advised that Bermuda meets the criteria set out in EIOPA’s methodology for equivalence assessments under Solvency II subject to certain caveats set out in EIOPA’s report. This advice has recently been updated pursuant to a request by the European Commission and, on December 19, 2014, EIOPA published a consultation paper presenting draft advice to the European Commission in which it supported key aspects of Bermuda’s regulatory regime with certain caveats. The next substantive step will be the publication of EIOPA’s final report, which will be submitted to EIOPA’s Board of Supervisors before being sent to the European Commission. EIOPA's advice is expected to allow the European Commission to take informed decisions this year on whether solvency and prudential regimes in Bermuda (as well as Japan and Switzerland) are equivalent to Solvency II.
TAX MATTERS
The following summary of the taxation of ACGL and the taxation of our shareholders is based upon current law and is for general information only. Legislative, judicial or 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 ACGL—Bermuda” and “—Taxation of Shareholders—Bermuda Taxation” is based upon the advice of Conyers Dill & Pearman Limited, Hamilton, Bermuda and (b) under “—Taxation of ACGL—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 ACGL). The summary is based upon current law and is for general information only. The tax treatment of a holder of our shares (common shares or series C non-cumulative 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 ACGL
Bermuda
Under current Bermuda law, ACGL is not subject to tax on income or profits, withholding, capital gains or capital transfers. ACGL has obtained from the Minister of Finance under the Exempted Undertakings Tax Protection Act 1966 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 ACGL 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 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
ACGL 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 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 ACGL or its non-U.S. subsidiaries are or have been engaged in a trade or business in the United States. 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 United States (the “Treaty”), ACGL'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 United States. No regulations interpreting the Treaty have been issued. While there can be no assurances, ACGL does not believe that any of its Bermuda insurance subsidiaries has a permanent establishment in the United States. Such subsidiaries would not be entitled to the benefits of the Treaty if (i) less than 50% of ACGL'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, ACGL 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 ACGL’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 United States 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 ACGL's non-U.S. insurance subsidiaries is considered to be engaged in the conduct of an insurance business in the United States, a significant portion of such company's investment income could be subject to U.S. income tax.

46



Non-U.S. corporations not engaged in a trade or business in the United States 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 United States 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 United States 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 United States. 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.
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 worldwide profits. Arch Re Europe U.K. Branch will be subject to U.K. corporation tax on the profits (both income profits and chargeable gains) attributable to the branch. The main rate of U.K. corporation tax for the financial year starting April 1, 2014 is 21% on profits. It has been announced that the U.K. corporation tax rate for the financial year starting April 1, 2015 will be 20% on profits.
Canada
In January 2005, Arch Insurance received its federal license to commence underwriting in Canada and began writing business in the first quarter of 2005 through its branch operation. Effective January 1, 2013, the branch operation was domesticated into Arch Insurance Canada, a Canadian federal insurance company subsidiary of Arch Insurance. 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 10% and 16%.
Ireland
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 2011. Arch Underwriters Europe Limited was registered by the CBOI as an insurance and reinsurance intermediary in July 2014. 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 Arch Re Europe Swiss Branch and its U.K. branch. Any creditable foreign tax (i.e., Swiss or U.K.) payable will be creditable against Arch Re Europe’s Irish corporate tax liability on the results of Arch Re Europe’s Swiss and U.K. branches. The current rate of Irish corporation tax applicable to such profits is 12.5%.
Switzerland
Arch Re Europe Swiss Branch and Arch Underwriters Europe Swiss Branch are subject to Swiss corporation tax on the profit which is allocated to the branch. The effective tax rate is approximately 21.12% for Swiss federal, cantonal and communal corporation taxes on the profit. The effective tax rate of the annual cantonal and communal capital taxes on the equity which is allocated to Arch Re Europe Swiss Branch and Arch Underwriters Europe Swiss Branch is approximately 0.14%.
Denmark
Arch Re Denmark, established as a subsidiary of Arch Re Bermuda, is subject to Danish corporation taxes on its profits at a rate of 25% for 2013 and the preceding years. For 2014, the corporate tax rate has been reduced to 24.5%, for 2015 to 23.5% and for 2016 and onwards to 22%.
Taxation of Shareholders
The following summary sets forth certain United States federal income tax considerations related to the purchase, ownership and disposition of our common shares and our series C non-cumulative preferred shares (“preferred shares”). Unless otherwise stated, this summary deals only with shareholders (“U.S. Holders”) that are United States Persons (as

47



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 United States federal income tax matters described herein and does not purport to address all of the United States 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 United States federal income tax consequences that may be relevant to certain types of shareholders, such as banks, insurance companies, regulated investment companies, real estate investment trusts, financial asset securitization investment trusts, dealers in securities or traders that adopt a mark-to-market method of tax accounting, tax exempt organizations, expatriates or 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. This discussion is based upon the Code, the Treasury regulations promulgated there under and any relevant administrative rulings or pronouncements or judicial decisions, all as in effect on the date of this annual report and as currently interpreted, and does not take into account possible changes in such tax laws or interpretations thereof, which may apply retroactively. This discussion does not include any description of the tax laws of any state or local governments within the United States, 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 United States 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 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 “United States Person” means:
a citizen or resident of the United States,
a corporation or entity treated as a corporation created or organized in or under the laws of the United States, any state thereof, or the District of Columbia,
an estate the income of which is subject to United States federal income taxation regardless of its source,
a trust if either (x) a court within the United States is able to exercise primary supervision over the administration of such trust and one or more United States persons have the authority to control all substantial decisions of such trust or (y) the trust has a valid election in effect to be treated as a United States 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.
Bermuda Taxation
Currently, there is no Bermuda withholding tax on dividends paid by us.
United States Taxation
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 CFC, “related person insurance income” (“RPII”) and 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 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 United States 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 ACGL 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

48



preferred shares will be considered readily tradable on an established securities market in the United States. 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.
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.
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 United States 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
Under our bye-laws, the 9.9% voting restriction applicable to the Controlled Shares of a U.S. Person (as defined in our bye-laws) generally does not apply to certain of our investors. Depending upon the ownership of these investors and as a result of certain attribution rules, we and our foreign subsidiaries could be controlled foreign corporations (“CFCs”). That status as a CFC would not cause us or any of our 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 considered to own less than 10% of the total combined voting power of our shares or those of our foreign subsidiaries. Only U.S. Holders that are considered to own 10% or more of the total combined voting power of our shares or those of our foreign subsidiaries (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 there under) (a “10% U.S. Voting Shareholder”) would be affected by our status as a CFC. The preferred shares generally should not be considered voting stock for purposes of determining whether a United States Person would be a 10% U.S. Voting Shareholder. The shares may, however, become entitled to vote (as a class along with any other class of preferred shares of ACGL then outstanding) for the election of two additional members of the board of directors of ACGL if ACGL does not declare and pay dividends for the equivalent of six or more dividend periods. In such case, the preferred shares should be treated as voting stock for as long as such voting rights continue. Our bye-laws are intended to prevent any U.S. Holder from being considered a 10% U.S. Voting Shareholder by limiting 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. However, because under our bye-laws certain funds associated with Warburg Pincus LLC and Hellman & Friedman LLC generally are entitled to vote their directly owned common shares in full, a U.S. Holder that is attributed (under the Code or the regulations there under) common shares owned by such funds may be considered a 10% U.S. Voting Shareholder. If we

are a CFC, a U.S. Holder that is considered a 10% U.S. Voting 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 ACGL 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 realized on a sale or other disposition (including by way of repurchase or liquidation) of our shares to the extent of the current and accumulated earnings and profits attributable to such shares.
While our bye-laws are intended to prevent any member from being considered a 10% U.S. Voting Shareholder (except as described above), there can be no assurance that a U.S. Holder will not be treated as a 10% U.S. Voting Shareholder, by attribution or otherwise, under the Code or any applicable regulations there under.
Related Person Insurance Income Rules
Generally, we do not expect the gross RPII (related person insurance income) 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 and do not expect the direct or indirect insureds (and related persons) of any such subsidiary to directly or indirectly own 20% or more of either the voting power or value of our stock. 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.
Section 953(c)(7) of the Code generally provides that Section 1248 of the Code (which generally would require a U.S. Holder to treat certain gains attributable to the sale, exchange or disposition of common shares or preferred shares as a dividend) will apply to the sale or exchange by a U.S. shareholder of shares in a foreign corporation that is characterized as a CFC under the RPII rules if the foreign corporation would be taxed as an insurance company if it were a domestic corporation, regardless of whether the U.S. shareholder is a 10% U.S. Voting Shareholder or whether the corporation qualifies for either the RPII 20% ownership exception or 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 ACGL 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 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 “passive foreign investment companies” (“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

50



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 ACGL is not a PFIC, no income tax consequences would result.
For any year in which ACGL is a PFIC, the shareholder would include in its taxable income a proportionate share of the net ordinary income and net capital gains of ACGL and certain of its non-U.S. subsidiaries.
The PFIC statutory provisions contain an express exception for income “derived in the active conduct of an insurance business by a corporation which is predominantly engaged in an insurance business…” This exception is intended to ensure that income derived by a bona fide insurance company is not treated as passive income, except to the extent such income is attributable to financial reserves in excess of the reasonable needs of 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 are not a PFIC, 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.
No regulations interpreting the substantive PFIC provisions have yet been issued. The Commissioner of the IRS has indicated that guidance on certain PFIC issues should be issued shortly. Each U.S. Holder should consult his tax advisor as to the effects of these rules.
Proposed Legislation
On November 19, 2013, Senate Finance Committee then-Chairman Max Baucus (D-MT) released a tax reform discussion draft on international tax issues. A provision in the discussion draft would change the definition of a U.S. shareholder for CFC purposes and overhaul the PFIC rules, including eliminating the PFIC exception for certain insurance companies. On February 26, 2014, the House Ways and Means Committee Chairman Dave Camp published a tax reform proposal titled “Tax Reform Act of 2014,” which was subsequently introduced to the Congress on December 11, 2014. The bill contains a provision that would significantly modify the PFIC exception for certain insurance companies.
Prospective investors should consult their own tax advisor regarding the likelihood that the provisions in these discussion drafts and tax reform proposal are enacted and any effect of such provisions.
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 United States Persons (“Non-U.S. holders”) generally will not be subject to United States 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 United States or such person is present in the United States 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 United States or is a United States person. No U.S. backup withholding will apply to payments of dividends, if any, on our common shares or our preferred shares.

51



Sections 1471 through 1474 to the Code, known as the Foreign Account Tax Compliance Act (“FATCA”), impose a withholding tax of 30% on (i) U.S.-source interest, dividends and certain other types of income, and (ii) the gross proceeds from the sale or disposition of assets which produce such types of income, which are 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 United States is in the process of negotiating intergovernmental agreements to implement FATCA (“IGAs”) with a number of jurisdictions. Bermuda has signed an IGA with the United States. Different rules than those described above may apply under such an IGA.
Withholding on U.S.-source interest, dividends and certain other types of income applies from July 1, 2014, and withholding on gross proceeds will apply beginning on January 1, 2017. 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.
ITEM 1A. RISK FACTORS
Set forth below are risk factors relating to our business. You should also refer to 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.”
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 with major U.S. and non-U.S. insurers and reinsurers, many of which have greater financial, marketing and management resources than we do, as well as other potential providers of capital willing to assume insurance and/or reinsurance risk. We also compete with new companies that continue to be formed to enter the insurance and reinsurance markets. In addition, continued consolidation within the insurance and reinsurance industry will further enhance the already competitive underwriting environment. 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. In our insurance business, we compete with insurers that provide specialty property and casualty lines of insurance, including ACE Limited, Alleghany Corporation, Allied World Assurance Company, Ltd., American International Group, Inc., AXIS Capital Holdings Limited, Berkshire Hathaway, Inc., Chubb Corporation, CNA, Endurance Specialty Holdings Ltd., The Hartford Financial Services Group, Inc., HCC Insurance Holdings, Inc., Ironshore Inc., Liberty Mutual Insurance, Lloyd’s, Markel Insurance Company, RLI Corp., The Travelers Companies, W.R. Berkley Corp., XL Group plc and Zurich Insurance Group. In our reinsurance business, we compete with reinsurers that provide property and casualty lines of reinsurance, including ACE Limited, Alleghany Corporation, Argo International Holdings, Ltd., AXIS Capital Holdings Limited, Berkshire Hathaway, Inc., Endurance Specialty Holdings Ltd., Everest Re Group Ltd., Hannover Rückversicherung AG, Lloyd’s, Markel Global Reinsurance, Montpelier Re Holdings Ltd., Munich Re Group, PartnerRe Ltd., Platinum Underwriters Holdings, Ltd., RenaissanceRe Holdings Ltd., Swiss Reinsurance Company, Third Point Reinsurance Ltd., Validus Holdings Ltd. and XL Group plc. We do not believe that we have a significant market share in any of our markets.
Financial institutions and other capital markets participants also offer alternative products and services similar to our own or alternative products that compete with insurance and reinsurance products, such as insurance/risk-linked securities, catastrophe bonds and derivatives. In recent years, capital market participants have been increasingly active in the reinsurance market and markets for related risks. Certain of the 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 further downward pressure on premium rates. In this regard, in 2014 we sponsored a new property and casualty reinsurer,

52



Watford Re, along with Highbridge. We perform underwriting services and Highbridge manages the investments, seeking higher yields and potentially assuming more risk than in our investment portfolio. If the investment and/or insurance underwriting strategy is not successful, we may be exposed to a risk of loss on our investment and in respect of the reinsurance cessions. In addition, we may not be aware of other companies that may be planning to enter the segments of the insurance and reinsurance market in which we operate.
Our competitive position is based on many factors, including our perceived overall financial strength, ratings assigned by independent rating agencies, geographic scope of business, client and broker relationships, premiums charged, contract terms and conditions, products and services offered (including the ability to design customized programs), appropriate and timely claim payments, reputation, experience and qualifications of employees and local presence. We may not be successful in competing with others on any of these bases, and the intensity of competition in our industry may erode profitability and result in less favorable policy terms and conditions for insurance and reinsurance companies generally, including us.
In our mortgage business, we compete with six active U.S. mortgage insurers, which include the mortgage insurance subsidiaries of Essent Group Ltd., Genworth Financial Inc., MGIC Investment Corporation, NMI Holdings Inc., Radian Group Inc. and United Guaranty Corporation. The level of competition within the private mortgage insurance industry has been intense and is not expected to diminish. In response to competitive pressures, among other factors, we reduced premium rates for both borrower-paid and lender-paid products in 2014. We are observing an increase in the number of lenders requesting customized lender-paid premium rate programs. In addition to pricing, we compete with other private mortgage insurers on the basis of terms and conditions, underwriting guidelines, loss mitigation practices, financial strength, reputation, customer relationships, technology, service and other factors. One or more private mortgage insurers may seek increased market share by reducing pricing, or loosening their underwriting guidelines or practices, which could adversely affect our mortgage insurance operations. 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.
The mortgage insurance industry’s business has been limited as a result of competition with the FHA, which substantially increased its market share beginning in 2008. In January 2015, FHA reduced the annual mortgage insurance premium it charges from 1.35% of the loan amount to 0.85%. This premium reduction will make private mortgage insurance less competitive with the FHA for borrowers with certain credit characteristics. Other factors that could cause FHA to maintain or increase its share of the mortgage insurance market include:
a further reduction in the premiums charged for government mortgage insurance or a loosening of underwriting guidelines;
imposition of additional loan level fees by the government sponsored entities (“GSEs”), Fannie Mae and Freddie Mac, on loans that require mortgage insurance;
increases in GSE guaranty fees and the difference in the spread between Fannie Mae mortgage-backed securities (“MBS”) and Ginnie Mae MBS; and
the implementation of new regulations under the Dodd-Frank Act and the Basel III Rules.
If the FHA or other government-sponsored mortgage insurance programs maintain or increase their share of the mortgage insurance market, our mortgage insurance business could be adversely affected.
In addition to FHA and other federal mortgage insurance programs, lenders and investors may select other alternatives to private mortgage insurance, including:
state-supported mortgage insurance funds in several states;
lenders and other investors holding mortgages in portfolio and self-insuring;
investors using credit enhancements other than mortgage insurance, using other credit enhancements in conjunction with reduced levels of mortgage insurance coverage, or accepting credit risk without credit enhancement; and
lenders originating mortgages using “piggy-back” structures to avoid mortgage insurance, such as a first mortgage with an 80% loan-to-value and a second mortgage with a 10%, 15% or 20% loan-to-value (referred to

53



as 80-10-10, 80-15-5 or 80-20 loans, respectively) rather than a first mortgage with a 90%, 95% or 100% loan-to-value that has mortgage insurance.
In our reinsurance and other risk sharing products, we have seen increased competition from other 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 credit risk is borne by private capital.
Any alternatives to private mortgage insurance that develop could adversely affect our operations. Any failure by us to effectively compete within and outside the mortgage insurance industry 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. As a result, the value of our securities, including our common shares and preferred shares, may fluctuate widely.
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, tornados, explosions, severe winter weather, fires, droughts and other natural disasters. 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 catastrophic events may vary materially from estimates due to the inherent uncertainties in making such determinations resulting from several factors, including the potential inaccuracies and inadequacies in the data provided by clients, brokers and ceding companies, the modeling techniques and the application of such techniques, the contingent nature of business interruption exposures, the effects of any resultant demand surge on claims activity and attendant coverage issues.
In 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 and cause substantial volatility in our results of operations, which could have a material adverse effect on our ability to write new business and cause the value of our securities, including our common shares and preferred shares, to fluctuate widely.
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.

54



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. 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 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 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 85% of their respective losses for 2015, 84% for 2016, 83% for 2017, 82% for 2018, 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 2015 is $100 million and will increase by $20 million per year until it becomes $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.
The insurance and reinsurance industry is subject to regulatory and legislative initiatives or proposals from time to time which could adversely affect our business.
From time to time, various regulatory and legislative changes have been proposed in the insurance and reinsurance industry. Among the proposals that are at present being considered are the possible introduction of global regulatory standards for the amount of capital that insurance groups must maintain across the group.
The extreme turmoil in the financial markets has increased the likelihood of changes in the way the financial services industry is regulated. 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. While we cannot predict the exact nature, timing or scope of possible governmental initiatives, there may be increased regulatory intervention in our industry in the future. For example, the U.S. federal government has increased its scrutiny of the insurance regulatory framework in recent years, and some state legislators have considered or enacted laws that will alter and likely increase state regulation of insurance and reinsurance companies and holding companies. Moreover, the NAIC, which is an association of the insurance commissioners of all 50 states and the District of Columbia, regularly reexamines existing laws and regulations. There are also a variety of proposals being considered by various state legislatures.
Solvency II, the EU regulatory regime which was adopted in November 2009, imposes new solvency and governance requirements across all EU Member States. Although Solvency II was originally supposed to have become effective by November 1, 2012, it has been the subject of a number of delays in its implementation, and two “quick-fix” directives each pushed the implementation date back from an original implementation date of November 1, 2012. The most recent directive that amends Solvency II, the Omnibus II directive (Directive 2014/51/EU), was published and came into force in May 2014. Solvency II must now be transposed into the national law of each Member State by March 31, 2015 and implemented by firms by January 1, 2016.
The detail of the Solvency II project will be set out in “delegated acts” and binding technical standards which will be issued by the European Commission and will be legally binding. A delegated act, which sets out more detailed requirements for individual insurance undertakings as well as for groups based on the overarching provisions of Solvency II and which will make up the core of the single prudential rulebook for insurance and reinsurance undertakings in the EU, was published by the European Commission on October 10, 2014 and came into force on January 18, 2015. Solvency II imposes significant requirements for our EU-based regulated companies which require substantial documentation and implementation effort. Regulators in Bermuda and other jurisdictions in which we operate are also considering various proposals for financial and regulatory reform. The BMA has implemented and imposed additional requirements on the companies it regulates, such as Arch Re Bermuda, as part of its efforts to achieve equivalence under Solvency II. While the BMA regulates Arch Re Bermuda as a long-term and general business insurer under the Insurance Act in Bermuda, the impact of the Group Rules may have an adverse effect on ACGL and our operations. The future impact of such initiatives, if any, on our results of operations or our financial condition cannot be determined at this time. We are unable to predict

55



whether any of these laws and regulations will be adopted, the form in which any such laws and regulations would be adopted, or the effect, if any, these developments would have on our operations and financial condition, including the capital we are required to hold. Although EIOPA published draft advice to the European Commission on December 19, 2014 supporting key aspects of Bermuda’s regulatory regime, with certain caveats, and is due to publish its final report on this issue, it is unclear exactly when the European Commission will take a final decision on whether or not it will recognize the solvency regime in Bermuda to be equivalent to that laid down in Solvency II. If the European Commission does not recognize the regime in Bermuda to be equivalent, this could have an adverse effect on our operations.
The U.S. mortgage insurance industry is subject to substantial federal and state regulation, which has increased in recent years. The U.S. mortgage insurance industry is also subject to increased federal and state regulatory scrutiny (including by state insurance regulatory authorities), which could generate new regulations, regulatory actions or investigations. Failure to comply with federal and state regulations promulgated by federal consumer protection authorities and state insurance regulatory authorities could lead to enforcement or disciplinary action, including the imposition of penalties and the revocation of our authorization to operate.
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.
As of December 31, 2014, our reserves for unpaid losses and loss adjustment expenses, net of unpaid losses and loss adjustment expenses recoverable, were approximately $7.26 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, 2014.
In accordance with mortgage insurance industry practice, we only establish loss reserves for loans in our existing default inventory. Because our mortgage insurance reserving process does not take account of the impact of future losses from loans that are not in default, 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 loans in default, 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

56



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.
The failure of any of the loss limitation methods we employ could have a material adverse effect on our financial condition or results of operations.
We have large aggregate exposures to natural and man-made catastrophic events. 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 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 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. One or more catastrophic or other 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 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. We reserve the right to change this threshold at any time. Net probable maximum loss estimates are net of expected reinsurance recoveries, before income tax and before excess reinsurance reinstatement premiums. Loss estimates are reflective of the zone indicated and not the entire portfolio. Since hurricanes and windstorms can affect more than one zone and make multiple landfalls, our loss estimates include clash estimates from other zones. Our 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 from one or more catastrophic 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. Catastrophe modeling is a relatively new discipline that utilizes a mix of historical data, scientific theory and mathematical methods. We believe that there is considerable uncertainty in the data and parameter inputs for insurance industry catastrophe models. In that regard, there is no universal standard in the preparation of insured data for use in the models and the running of modeling software. In our view, the accuracy of the models depends heavily on the availability of detailed insured loss data from actual recent large catastrophes. Due to the limited number of events, there is significant potential for substantial differences between the modeled loss estimate and actual company experience for a single large catastrophic event. This potential difference could be even greater for perils with less modeled annual frequency, such as U.S. earthquake, or less modeled annual severity, such as European windstorm. We are also reliant upon third-party estimates of industry insured exposures and there is significant variation possible around the relationship between our loss and that of the industry following a catastrophic 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” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Natural and Man-Made Catastrophic Events.” Depending on business opportunities and the mix of business that may comprise our insurance and reinsurance portfolio, we may seek to adjust our self-imposed limitations on probable maximum pre-tax loss for catastrophe exposed business.
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.
While reinsurance and retrocessional coverage will be used to limit our exposure to risks, the availability of such arrangements 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.
For the purposes of managing risk, we use reinsurance and also may use retrocessional arrangements. In the normal course of business, our insurance subsidiaries cede a portion of their premiums through pro rata, excess of loss and facultative reinsurance agreements. Our reinsurance subsidiaries purchase a limited amount of retrocessional coverage as part of their aggregate risk 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. 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 retrocessionnaires 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 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

58



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.
Unexpected political legislative or judicial developments related to coverage may adverse affect us.
The effects of emerging claims and coverage issues are uncertain. The insurance industry is also affected by political, judicial and legal developments which have in the past resulted in 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.
The insurance businesses in which we operate may be subject to periodic negative publicity which may negatively impact our financial results.
Our products and services are ultimately distributed to individual and business customers. From time to time, consumer advocacy groups or the media may focus attention on insurance products and services, thereby subjecting the industry to periodic negative publicity. We also may be negatively impacted if competitors in one or more of our markets engage in practices resulting in increased public attention to our business. These factors may further increase our costs of doing business and adversely affect our profitability by impeding our ability to market our products and services, requiring us to change our products or services or by increasing the regulatory burdens under which we operate.
Changes in current accounting practices and future pronouncements may materially impact our reported financial results.
Developments in accounting practices, for example a convergence of U.S. GAAP with IFRS, may require considerable additional expense to comply with, particularly if we are required to prepare information relating to prior periods for comparable purposes or to apply the new requirements retroactively. The impact of changes in current accounting practices and future pronouncements cannot be predicted, but may affect the results of our operations, including among other things, the calculation of net income.
Risks Relating to Our Company
Our success will depend on our ability to maintain and enhance effective operating procedures and internal controls and our 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 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. Any ineffectiveness in our controls or procedures could have a material adverse effect on our business.

The NAIC has increased its focus on risks within an insurer’s holding company system that may pose enterprise risk to the insurer. In 2010, the NAIC adopted amendments to its Model Insurance Holding Company System Regulatory Act and Regulation, which include, among other amendments, a requirement for the ultimate controlling person to file an enterprise risk report. In 2012, the NAIC adopted the ORSA 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 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, applicable to the insurer and/or the insurance group of which it is a member. 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.
A downgrade in our ratings or our inability to obtain a rating for our operating insurance and reinsurance subsidiaries may adversely affect our relationships with clients and brokers and negatively impact sales of our products.
Our operating insurance and reinsurance subsidiaries are rated by ratings agencies. Brokers negotiate contracts of insurance between insured and insurer on behalf of the insured and intermediaries negotiate contracts of reinsurance between a primary insurer and reinsurer, on behalf of the primary insurer. 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, insurers, ceding insurers and 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. Our financial strength ratings 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. We can offer no assurances that our ratings will remain at their current 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 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.
In light of the difficulties experienced recently by many financial institutions, including our competitors in the insurance industry, 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.
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.

Technology breaches or failures, including, but not limited to, those resulting from a malicious cyber attack on us or our business partners and service providers, could disrupt or otherwise negatively impact our business.
We rely on information technology systems to process, transmit, store and protect the electronic information, financial data and proprietary models that are critical to our business. Furthermore, a significant portion of the communications between our employees and our business partners and service providers depends on information technology and electronic information exchange. Like all companies, our information technology systems 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 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. An incident could also result in a violation of applicable privacy and other laws, damage our reputation, cause a loss of customers or give rise to monetary fines and other penalties, which could be significant.
We believe that we have established and implemented appropriate security measures, controls and procedures to safeguard our information technology systems and to prevent unauthorized access to such systems and any data processed and/or stored in such systems, and we periodically employ third parties to evaluate and test the adequacy of such systems, controls and procedures. In addition, we have established a comprehensive business continuity plan which is designed to ensure that we are able to maintain all aspects of our key business processes functioning in the midst of certain disruptive events, including any disruptions to or breaches of our information technology systems. Our business continuity plan is routinely tested and evaluated for adequacy. Despite these safeguards, disruptions to and breaches of our information technology systems are possible and because we rely on our technology systems for many critical functions, including connecting with our customers, if such systems were to fail or become outmoded, 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.
It is possible that insurance policies we have in place with third parties would not entirely protect us in the event that we experienced a breach, interruption or widespread failure of our information technology systems. Furthermore, we have not secured any insurance coverage designed to specifically protect us from the result of such events. Although we have experienced no known or threatened cases involving unauthorized access to our information technology systems and data or unauthorized appropriation of such data to date, we have no assurance that such technology breaches will not occur in the future.
The preparation of our financial statements requires us to make many estimates and judgments, which are even more difficult than those made in a mature company since relatively limited historical information has been reported to us through December 31, 2014.
The preparation of consolidated financial statements 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, investment valuations, 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, 2014. Instead, our current loss reserves are primarily based on estimates of exposures on reported claims and estimates involving actuarial and statistical projections of our expectations of the ultimate settlement and administration costs of claims incurred but not yet reported. We utilize actuarial models as well as historical insurance industry loss development patterns to establish our initial loss reserves. Over time, other common reserving methodologies have begun to be employed. Actual claims and claim expenses paid may deviate, perhaps substantially, from the reserve estimates reflected in our financial statements.
The price of our common shares may be volatile.
There has been significant volatility in the market for equity securities. During 2014 and 2013, the price of our common shares fluctuated from a low of $52.23 to a high of $60.10 and from a low of $44.00 to a high of $59.78, respectively. On February 20, 2015, our common shares closed at a price of $60.04. The price of our common shares may not remain at or

61



exceed current levels. The following factors, in addition to those described in other risk factors above, may have an adverse impact on the market price of our common stock:
actual or anticipated variations in our quarterly results, including as a result of catastrophes or our investment performance;
