PART I. FINANCIAL INFORMATION

Cautionary Note Regarding Forward-Looking Statements

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

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

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

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

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

our ability to maintain or improve our ratings, which may be affected by our ability to raise additional equity or debt financings, by ratings agencies’ existing or new policies and practices, as well as other factors described herein;

general economic and market conditions (including inflation, interest rates, unemployment, housing prices, foreign currency exchange rates, prevailing credit terms and the depth and duration of a ~~recession)~~recession, including those resulting from COVID-19) and conditions specific to the reinsurance and insurance markets ~~(including the length and magnitude of the current “soft” market)~~ in which we operate;

competition, including increased competition, on the basis of pricing, capacity (including alternative sources of capital), coverage terms, or other factors;

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

our ability to successfully enhance, integrate and maintain operating procedures (including information technology) to effectively support our current and new business;

the loss of key personnel;

accuracy of those estimates and judgments utilized in the preparation of our financial statements, including those related to revenue recognition, insurance and other reserves, reinsurance recoverables, investment valuations, intangible assets, bad debts, income taxes, contingencies and litigation, and any determination to use the deposit method of accounting, which for a relatively new insurance and reinsurance company, like our company, are even more difficult to make than those made in a mature company since relatively limited historical information has been reported to us through September 30, 2019;accounting;

greater than expected loss ratios on business written by us and adverse development on claim and/or claim expense liabilities related to business written by our insurance and reinsurance subsidiaries;

severity and/or frequency of losses;

claims for natural or man-made catastrophic events or severe economic events in our insurance, reinsurance and mortgage businesses could cause large losses and substantial volatility in our results of operations;

the effect of climate change on our business;

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

the effect of contagious disease (including COVID-19) on our business;

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;

Table of Contents

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;

changes in the method for determining the London Inter-bank Offered Rate (“LIBOR”) and the potential replacement of LIBOR;

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

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

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

a disruption caused by cyber-attacks or other technology breaches or failures on us or our business partners and service providers, which could negatively impact our business and/or expose us to litigation;

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

•

the other matters set forth under Item 1A “Risk Factors”, Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and other sections of our Annual Report on Form 10-K for the year ended December 31, 2019, “ITEM 1A—Risk Factors” of this Form 10-Q as well as the other factors set forth in our other documents on file with the SEC, and management’s response to any of the aforementioned factors.

Report of Independent Registered Public Accounting Firm

To theBoard of Directors and Shareholders of Arch Capital Group Ltd.

Results of Review of Interim Financial Statements

We have reviewed the accompanying consolidated balance sheet ofArch Capital Group Ltd. and its subsidiaries~~(the~~ (the “Company”) as of~~September~~ June 30, ~~2019,~~2020, and the relatedconsolidatedstatements of income, comprehensive income, and changes in shareholders’ equity for the three-month and ~~nine-month~~six-month periods ended~~September~~ June 30, 2020 and 2019, ~~and2018,~~ and the consolidated statements of cash flows for the ~~nine-month~~six-month periods ended ~~September~~June 30, 2020 and 2019, ~~and 2018,~~including the related notes (collectively referred to as the “interim financialstatements”).Based on our reviews, we are not aware of any material modifications that should be made to the accompanying interim financial statementsfor them to be in conformity with accounting principles generally accepted in the United States of America.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidatedbalance sheet of the Company as of December 31, ~~2018,~~2019, and the related consolidatedstatements of income, comprehensive income, changes in shareholders’ equity, and cash flowsfor the year then ended (not presented herein), and in our report dated February 28, ~~2019,~~2020, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying consolidated balance sheet as of December 31, ~~2018,~~2019, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Basis for Review Results

These interim financial statements arethe responsibility of the Company’s management.We are a public accounting firm registered with the ~~Public Company Accounting Oversight Board (United States) (PCAOB)~~PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our review in accordance with the standards of the PCAOB. A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

ARCH CAPITAL GROUP LTD. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1. Basis of Presentation and Recent Accounting Pronouncements

General

Arch Capital Group Ltd. (“Arch Capital”) is a Bermuda public limited liability company which provides insurance, reinsurance and mortgage insurance on a worldwide basis through its wholly-owned subsidiaries. As used herein, the “Company” means Arch Capital and its subsidiaries. The Company’s consolidated financial statements include the results of Watford Holdings Ltd. and its wholly owned subsidiaries (“Watford”). Watford is a multi-line Bermuda reinsurance company. Watford’s own management and board of directors are responsible for its results and profitability. See note 1112.

On January 1, 2019, the Company’s U.K. insurance operations entered into a transaction with The Ardonagh Group to acquire renewal rights for a U.K. commercial lines book of business, consisting of commercial property, casualty, motor, professional liability, personal accident and travel business.

Basis of Presentation

The interim consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). All significant intercompany transactions and balances have been eliminated in consolidation. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates and assumptions. In the opinion of management, the accompanying unaudited interim consolidated financial statements reflect all adjustments (consisting of normally recurring accruals) necessary for a fair statement of results on an interim basis. The results of any interim period are not necessarily indicative of the results for a full year or any future periods.

Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted; however, management believes that the disclosures are adequate to make the information presented not misleading. This report should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, ~~2018~~2019 (“~~2018~~2019 Form 10-K”), including the Company’s audited consolidated financial statements and related notes.

The Company has reclassified the presentation of certain prior year information to conform to the current presentation. Such reclassifications had no effect on the Company’s net income, comprehensive income, shareholders’ equity or cash flows. Tabular amounts are in U.S. Dollars in thousands, except share amounts, unless otherwise noted.

Recent Accounting Pronouncements

Recently Issued Accounting Standards Adopted

The Company adopted ASU ~~2016-02, “Leases~~2018-13, “Fair Value Measurement (Topic ~~842)”, which provides a new comprehensive model~~820): Disclosure Framework - Changes to the Disclosure Requirements for ~~lease accounting. Topic 842 requires a lessee to recognize a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use~~Fair Value Measurement.” The ASU modifies the ~~underlying asset for the lease term. The Company adopted the modified retrospective approach of this standard, that resulted in the recognition of a right-of-use asset of $147.9 million~~disclosure requirements on fair value measurement as part of ~~other assets and a lease liability~~the disclosure framework project with the objective to improve the effectiveness of ~~$163.6 million as part of other liabilities~~disclosures in the ~~consolidated balance sheet as of January 1, 2019. The Company de-recognized the liability for deferred rent that was required under the previous guidance.~~

In addition, the Company adopted ASU 2018-11, “Leases: Targeted Improvements (Topic 842),” which provides an additional (optional) transition method to adopt the new lease standard. The Company adopted the alternative transition method and elected to utilize a cumulative-effect adjustmentnotes to the ~~opening balance~~financial statements. The amendments in this update allow for removal of (1) the amount and reasons for transfer between Level 1 and Level 2 of the retained earnings for the year of adoption. As such, the Company’s reporting for the comparative periods prior to the adoption continue to be presented in the financial statements in accordance with previous lease accounting guidance. The Company also adopted the practical expedients as a package which allows the Company to not reassess (1) whether any expired or existing contracts are or contain leasesfair value hierarchy; (2) the ~~lease classification~~policy for ~~any expired or existing leases~~transfers between levels; and (3) ~~initial direct costs~~the valuation processes for any existing leases and (4) to account for the lease and non lease components as a single lease component. In addition to electing the practical expedients as a package, the Company elected to include hindsight to determine the lease term of existing leases, and made an accounting policy election to not apply the recognition requirements to short-term leases (lease term of less than twelve months). The cumulative effect adjustment to the opening balance of retained earnings was 0.Level 3 fair value measurements. The adoption of ~~the updated~~this guidance did not have a material effect on the Company’s ~~results of operations or liquidity.~~consolidated financial statements.

The Company adopted ASU ~~2018-07 “Improvements to Nonemployee Share-Based Payment Accounting,~~2018-15, “Intangibles - Goodwill and Other - Internal Use Software (Subtopic 350-40).” ~~which was issued~~This ASU aligns the requirements for capitalizing certain implementation costs incurred in ~~June 2018 to simplify the accounting for share-based payments granted to nonemployees for goods and services. Under this ASU, most of the guidance on such payments to nonemployees would be aligned~~a cloud computing arrangement that is a service contract with the requirements for ~~share-based payments granted~~capitalizing implementation costs incurred to ~~employees.~~develop or obtain internal-use software. The guidance provides flexibility in adoption, allowing for either retrospective adjustment or prospective adjustment for all implementation costs incurred after the date of adoption. The Company adopted this guidance prospectively. The adoption of this guidance did not have a material effect on the Company’s consolidated financial statements.

In March 2020, the SEC amended Rule 3-10 of Regulation S-X regarding financial disclosure requirements for registered debt offerings involving subsidiaries as either issuers or guarantors and affiliates whose securities are pledged as collateral. This new guidance narrows the circumstances that require separate financial statements of subsidiary issuers and guarantors and streamlines the alternative disclosures required in lieu of those statements. The amendment is effective on January 4, 2021 with early adoption permitted. The Company elected to apply the amended requirements for the quarter ended March 31, 2020, and is no longer providing condensed consolidating financial information that resulted from the registered debt obligations of its subsidiaries, Arch Capital Group (U.S.) Inc. and Arch Capital Finance LLC., that were disclosed in Note 26 of the financial statements in the Company’s 2019 Form 10-K.

The Company adopted ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326).” The ASU ~~is effective~~applies a new credit loss model (current expected credit losses) for ~~reporting periods beginning after December 15,~~determining credit related impairments for financial instruments measured at amortized cost, including reinsurance recoverable, contractholder receivables, and premiums receivable, and requires an entity to estimate its lifetime “expected credit loss” and record an allowance that, when deducted from the

The estimate of expected credit losses should consider historical information, current information, as well as reasonable and supportable forecasts, including estimates of prepayments.

The ASU also amends the previous other-than-temporary impairment model for available-for-sale debt securities by requiring the recognition of impairments relating to credit losses through an allowance account and limits the amount of credit loss to the difference between a security’s amortized cost basis and its fair value. In addition, the length of time a security has been in an unrealized loss position ~~results~~will no longer impact the determination of ~~operations or cash flows.~~

whether a credit loss exists.

The Company adopted the ASU ~~2018-02 “Income Statement-Reporting Comprehensive Income (Topic 220) - Reclassification~~for the quarter ending March 31, 2020 by recognizing an after-tax cumulative effect adjustment of ~~Certain Tax Effects from Accumulated Other Comprehensive Income,” which was issued in February 2018~~$22.5 million to ~~allow~~ the ~~reclassification~~opening balance of retained earnings as of January 1, 2020. The cumulative effect adjustment decreased retained earnings and increased the allowance for credit losses.

Significant Accounting Policies

The following accounting policies have been updated to reflect the Company's adoption of the ~~stranded tax effects~~new accounting guidance on credit losses.

Investments

The Company conducts a periodic review to identify and evaluate credit based impairments related to the Company’s available for sale investments. The Company derives estimated credit losses by comparing expected future cash flows to be collected to the amortized cost of the security. Estimates of expected future cash flows consider among other things, macroeconomic conditions as well as the financial condition, near-term and long-term prospects for the issuer, and the likelihood of the recoverability of principal and interest. Effective January 1, 2020, credit losses are recognized through an allowance account subject to reversal, rather than a reduction in ~~accumulated~~amortized cost. Declines in value attributable to factors other than credit are reported in other comprehensive income ~~(“AOCI”) resulting from~~while the ~~Tax Cuts and Jobs Act of 2017 (“Tax Cuts Act”)~~allowance for credit loss is charged to net realized gains (losses). ~~Current guidance requires~~

For available for sale investments that the ~~effect of a change~~Company intends to sell or for which it is more likely than not that the Company would be required to sell before an anticipated recovery in ~~tax laws or rates on deferred tax balances to be reported in income from continuing operations in~~value, the ~~accounting period that includes the period of enactment, even if the related income tax effects were originally charged or credited directly to AOCI. The~~full amount of the ~~reclassification would include the effect~~impairment is included in net realized gains (losses). The new cost basis of the ~~change~~investment is the previous amortized cost basis reduced by the impairment recognized in net realized gains (losses). The new cost basis is not adjusted for any subsequent recoveries in fair value.

The Company reports accrued investment income separately from investment balances and has elected not to measure an

allowance for credit losses for accrued investment income. Any uncollectible accrued interest income is written off in the ~~U.S. federal corporate income tax rate~~period it is deemed uncollectible.

Reinsurance Recoverables

In the normal course of business, the Company’s subsidiaries cede a portion of their premium and losses through pro rata and excess of loss reinsurance agreements on a treaty or facultative basis. Reinsurance recoverables are recorded as assets, predicated on the ~~gross deferred tax~~reinsurers’ ability to meet their obligations under the reinsurance agreements. In certain instances, the Company obtains collateral, including letters of credit and trust accounts to further reduce the credit exposure on its reinsurance recoverables. The Company reports its reinsurance recoverables net of an allowance for expected credit loss. The allowance is based upon the Company’s ongoing review of amounts outstanding, the financial condition of its reinsurers, amounts and ~~related valuation allowances, if any, at~~form of collateral obtained and other relevant factors. A ratings based probability-of-default and loss-given-default methodology is used to estimate the ~~date~~allowance for expected credit loss. Any allowance for credit losses is charged to net realized gains (losses) in the period the recoverable is recorded and revised in subsequent periods to reflect changes in the Company’s estimate of expected credit losses.

Contractholder Receivables

Certain insurance policies written by the Company’s U.S. insurance operations feature large deductibles, primarily in its construction and national accounts line of business. Under such contracts, the Company is obligated to pay the claimant for the full amount of the ~~enactment~~claim. The Company is subsequently reimbursed by the policy holder for the deductible amount. These amounts are included on a gross basis in the consolidated balance sheet as contractholder payables and contractholder receivables. In the event that the Company is unable to collect from the policyholder, the Company would be liable for such defaulted amounts. Collateral, primarily in the form of letters of credit, cash and trusts, is obtained from the policyholder to mitigate the Company’s credit risk.

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

Premiums Receivable

Premiums receivable include amounts receivable from agents, brokers and insured that are both currently due and amounts not yet due on insurance, reinsurance and mortgage insurance policies. Premiums receivable balances are reported net of an allowance for expected credit losses. The Company monitors credit risk associated with premiums receivable through its ongoing review of amounts outstanding, aging of the ~~Tax Cuts Act~~receivable, historical loss data, and counterparty financial strength measures. The allowance also includes estimated uncollectible amounts related to ~~items~~dispute risk. In certain instances, credit risk may be reduced by the Company’s right to offset loss obligations or unearned premiums against premiums receivable. Any allowance for credit losses is charged to net realized gains (losses) in ~~AOCI.~~the period the receivable is recorded and revised in subsequent periods to reflect changes in the Company’s estimate of expected credit losses.

Recently Issued Accounting Standards Not Yet Adopted

In December 2019, the FASB issued ASU 2019-12, “Simplifying the Accounting for Income Taxes.” This ASU eliminates certain exceptions for recognizing deferred taxes for investments, performing intraperiod tax allocation and calculating income taxes in interim periods. The ~~updated guidance~~ASU also clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. The ASU is effective for ~~reporting periods~~fiscal years beginning after December 15, 2018 and is to be applied retrospectively to each period in which the effect of the Tax Cuts Act related to items remaining in AOCI are recognized or at the beginning of the period of adoption. The adoption of this ASU did not have a material effect on the Company’s results of operations, financial position or liquidity.

The Company adopted ASU 2017-08 “Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities,” which was issued in March, 2017. This ASU shortens the amortization period for certain callable debt securities held at a premium and requires the premium to be amortized to the earliest call date. However, the new guidance does not require an accounting change for securities held at a discount whose discount continues to be amortized to maturity. The standard is effective for financial statements issued for fiscal years,2020 and interim periods within those fiscal years ~~beginning after December 15, 2018,~~ with early adoption permitted. The ~~adoption~~Company is currently evaluating the impact of the new guidance ~~requires a modified retrospective approach with a cumulative-effect adjustment~~on its consolidated financial statements and does not expect this guidance to ~~retained earnings. The adoption of this ASU did not~~ have a material effect on the Company’s consolidated financial statements.

In March 2020, the FASB issued ASU 2020-04, “Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” This ASU provides optional expedients and exceptions for applying GAAP to investments, derivatives, or other transactions that reference the London Interbank Offered Rate (LIBOR) or another reference rate expected to be discontinued because of reference rate reform. Along with the optional expedients, the amendments include a general principle that permits an entity to consider contract modifications due to reference reform to be an event that does not require contract re-measurement at the modification date or reassessment of a previous accounting determination. This standard may be elected over time through December 31, 2022 as reference rate reform activities occur. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements and does not expect this guidance to have a material effect on the Company’s consolidated financial statements.

4. Segment Information

The Company classifies its businesses into 3 underwriting segments — insurance, reinsurance and mortgage — and 2 other operating segments — ‘other’ and corporate (non-underwriting). The Company determined its reportable segments using the management approach described in accounting guidance regarding disclosures about segments of an enterprise and related information. The accounting policies of the segments are the same as those used for the preparation of the Company’s consolidated financial statements. Intersegment business is allocated to the segment accountable for the underwriting results.

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

The insurance segment consists of the Company’s insurance underwriting units which offer specialty product lines on a worldwide basis. Product lines include: construction and national accounts; excess and surplus casualty; lenders products; professional lines; programs; property, energy, marine and aviation; travel, accident and health; and other (consisting of alternative markets, excess workers' compensation and surety business).

The reinsurance segment consists of the Company’s reinsurance underwriting units which offer specialty product lines on a worldwide basis. Product lines include: casualty; marine and aviation; other specialty; property catastrophe; property excluding property catastrophe (losses on a single risk, both excess of loss and pro rata); and other (consisting of life reinsurance, casualty clash and other).

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

The corporate (non-underwriting) segment results include net investment income, other income (loss), corporate expenses, transaction costs and other, interest expense, items related to the Company’s non-cumulative preferred shares, net realized gains or losses (which includes changes in the allowance for credit losses on financial assets and net impairment losses ~~included~~recognized in ~~earnings,~~earnings), equity in net income or loss of investment funds accounted for using the equity method, net foreign exchange gains or losses and income taxes. Such amounts exclude the results of the ‘other’ segment.

The ‘other’ segment includes the results of Watford (see note 1112). For the ‘other’ segment, performance is measured based on net income or loss.

~~property (including special risk other than marine) reserves~~At June 30, 2020 and December 31, 2019, approximately 63.1% and 61.2% of reinsurance recoverables on paid and unpaid losses (not including ceded unearned premiums) of $4.38 billion and $4.35 billion, respectively, were due from ~~the 2010~~carriers which had an A.M. Best rating of “A-” or better while 36.7% and ~~2017 accident years. Net favorable development in long-tailed lines reflected net reductions in executive assurance reserves~~38.8%, respectively, were from companies not rated. For items not rated, over 90% of ~~$8.0 million, primarily~~such amount was collateralized through reinsurance trusts or letters of credit at June 30, 2020 and December 31, 2019. The largest reinsurance recoverables from ~~the 2008 accident year,~~any one carrier were approximately 1.8% and ~~in healthcare reserves~~1.7%, of $8.1 million, primarily from the 2003 accident year. Net adverse development in medium-tailed lines reflected $23.4 million of adverse development in program business, primarily driven by a few inactive programs that were non-renewed in prior periodstotal shareholders’ equity available to Arch at June 30, 2020 and $42.1 million of adverse development on contract binding business, primarily from the 2014 to 2017 accident years. Such amounts were partially offset by $26.2 million of net favorable development in other medium-tailed lines, including professional liability and surety business, across most accident years.

December 31, 2019, respectively.

The reinsurance segment’s net favorable development of $103.9 million, or 11.4 loss ratio points, for the 2018 period consisted of $77.6 million from short-tailed lines and $26.3 million from long-tailed and medium-tailed lines. Favorable development in short-tailed lines included $56.4 million from property catastrophe and property other than property catastrophe reserves, across most underwriting years, reflecting lower levels of reported and paid claims activity than previously anticipated which led to decreases in certain loss ratio selections during the period, and $10.7 million from other specialty reserves, across most underwriting years. Favorable development in long-tailed and medium-tailed lines reflected reductions in casualty reserves of $16.0 million based on varying levels of reported and paid claims activity, primarily from the 2002 to 2010 underwriting years, and favorable development in marine reserves of $10.8 million across most underwriting years.Contractholder Receivables

The ~~mortgage segment’s net favorable development was $74.9 million, or 8.6 loss ratio points,~~following table provides a roll forward of the allowance for expected credit losses of the ~~2018 period.

See “—Securities Lending Agreements.”

Securities Lending Agreements

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

The Company receives collateral (shown as ‘Collateral received under securities lending, at fair value’ on the Company’s balance sheet) in the form of cash or U.S. government and government agency securities. ~~Cash~~At June 30, 2020, the fair value of the cash collateral ~~primarily consists~~received on securities lending was $26.6 million and the fair value of ~~short term investments.~~security collateral received was $447.2 million.

Certain of the Company’s other investments are in investment funds for which the Company has the option to redeem at agreed upon values as described in each investment fund’s subscription agreement. Depending on the terms of the various subscription agreements, investments in investment funds may be redeemed daily, monthly, quarterly or on other terms. Two common redemption restrictions which may impact the Company’s ability to redeem these investment funds are gates and lockups. A gate is a suspension of redemptions which may be implemented by the general partner or investment manager of the fund in order to defer, in whole or in part, the redemption request in the event the aggregate amount of redemption requests exceeds a predetermined percentage of the investment fund’s net assets which may otherwise hinder the general

partner or investment manager’s ability to liquidate holdings in an orderly fashion in order to generate the cash necessary to fund extraordinarily large redemption payouts. A lockup period

is the initial amount of time an investor is contractually required to hold the security before having the ability to redeem. If the investment funds are eligible to be redeemed, the time to redeem such fund can take weeks or months following the notification.

of the funds (which include changes in the market value of the underlying securities in the funds). Such investments are generally recorded on a one to three month lag based on the availability of reports from the investment funds.

~~Net Impairment Losses Recognized in Earnings~~

The Company performs quarterly reviews of its available for sale investments in order to determine whether declines in fair value below the amortized cost basis were considered other-than-temporary in accordance with applicable guidance.

Net impairment losses recognized in earnings $ (2,521 ) $ (1,124 )

~~Net impairment losses recognized in earnings in the 2019 periods were primarily related to foreign currency fluctuations and other impairments on corporate bonds and other securities.~~

The Company believes that the minimal amount of OTTI included in accumulated other comprehensive income at September 30, 2019 on the securities which were considered by the Company to be impaired was due to market and sector-related factors (~~i.e.~~, not credit losses). At September 30, 2019, the Company did not intend to sell these securities, or any other securities which were in an unrealized loss position, and determined that it is more likely than not that the Company will not be required to sell such securities before recovery of their cost basis.

8. Fair Value

Accounting guidance regarding fair value measurements addresses how companies should measure fair value when they are required to use a fair value measure for recognition or disclosure purposes under GAAP and provides a common definition of fair value to be used throughout GAAP. It defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly fashion between market participants at the measurement date. In addition, it establishes a three-level valuation hierarchy for the disclosure of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The level in the hierarchy within which a given fair value measurement falls is determined based on the lowest level input that is significant to the measurement (Level 1 being the highest priority and Level 3 being the lowest priority).

The levels in the hierarchy are defined as follows:


Level 1:	Inputs to the valuation methodology are observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets


Level 2:	Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument

~~for substantially the full term of the financial instrument~~


Level 3:	Inputs to the valuation methodology are unobservable and significant to the fair value measurement

Following is a description of the valuation methodologies used for securities measured at fair value, as well as the general classification of such securities pursuant to the valuation hierarchy. The Company reviews its securities measured at fair value and discusses the proper classification of such investments with investment advisers and others.

The Company determines the existence of an active market based on its judgment as to whether transactions for the financial instrument occur in such market with sufficient frequency and volume to provide reliable pricing information. The independent pricing sources obtain market quotations and actual transaction prices for securities that have quoted prices in active markets. The Company uses quoted values and other data provided by nationally recognized independent pricing sources as inputs into its process for determining fair values of its fixed maturity investments. To validate the techniques or models used by pricing sources, the Company's review process includes, but is not limited to: (i) quantitative analysis (e.g.,

comparing the quarterly return for each managed portfolio to its target benchmark, with significant differences identified and investigated); (ii) a review of the average number of prices obtained in the pricing process and the range of resulting fair values; (iii) initial and ongoing evaluation of methodologies used by outside parties to calculate fair value; (iv) a comparison of the fair value estimates to the Company’s knowledge of the current market; (v) a comparison of the pricing services' fair values to other pricing services' fair values for the same investments; and (vi) periodic back-testing, which includes randomly selecting purchased or sold securities and comparing the executed prices to the fair value estimates from the pricing service. A price source hierarchy was maintained in order to determine which price source would be used (i.e., a price obtained from a pricing service with more seniority in the hierarchy will be used over a less senior one in all cases). The hierarchy prioritizes pricing services based on availability and reliability and assigns the highest priority to index providers. Based on the above review, the Company will challenge any prices for a security or portfolio which are considered not to be representative of fair value. The Company did not adjust any of the prices obtained from the independent pricing sources at ~~September~~June 30, ~~2019.~~2020.

In certain circumstances, when fair values are unavailable from these independent pricing sources, quotes are obtained directly from broker-dealers who are active in the corresponding markets. Such quotes are subject to the validation procedures noted above. Where quotes are unavailable, fair value is determined by the Investment Manager using quantitative and qualitative assessments such as internally modeled values.

Fixed maturities

The Company uses the market approach valuation technique to estimate the fair value of its fixed maturity securities, when possible. The market approach includes obtaining prices from independent pricing services, such as index providers and pricing vendors, as well as to a lesser extent quotes from broker-dealers. The independent pricing sources obtain market quotations and actual transaction prices for securities that have quoted prices in active markets. Each source has its own proprietary method for determining the fair value of securities that are not actively traded. In general, these methods involve the use of “matrix pricing” in which the independent pricing source uses observable market inputs including, but not limited to, investment yields, credit risks and spreads, benchmarking of like securities, broker-dealer quotes, reported trades and sector groupings to determine a reasonable fair value.

The following describes the significant inputs generally used to determine the fair value of the Company’s fixed maturity securities by asset class:

•U.S. government and government agencies — valuations provided by independent pricing services, with all prices provided through index providers and pricing vendors. The Company determined that all U.S. Treasuries would be classified as Level 1 securities due to observed levels of trading activity, the high number of strongly correlated pricing quotes received on U.S. Treasuries and other factors. The fair values of U.S. government agency securities are generally determined using the spread above the risk-free yield curve. As the yields for the risk-free yield curve and the spreads for these securities are observable market inputs, the fair values of U.S. government agency securities are classified within Level 2.

•Corporate bonds — valuations provided by independent pricing services, substantially all through index providers and pricing vendors with a small amount through broker-dealers. The fair values of these securities are generally determined using the spread above the risk-free yield curve. These spreads are generally obtained from the new issue market, secondary trading and from broker-dealers who trade in the relevant security market. As the significant inputs used in the pricing process for corporate bonds are observable market inputs, the fair value of these securities are classified within Level 2. A small number of securities are included in Level 3 due to a low level of transparency on the inputs used in the pricing process. During the nine months ended September 30, 2019, the Company transferred $25.8 million of corporate bonds from Level 2 to Level 3 based on a review of the pricing of such securities, as described above.

•Mortgage-backed securities — valuations provided by independent pricing services, substantially all through pricing vendors and index providers with a small amount through broker-dealers. The fair values of these securities are generally determined through the use of pricing models (including Option Adjusted Spread) which use spreads to determine the expected average life of the securities. These spreads are generally obtained from the new issue market, secondary trading and from broker-dealers who trade in the relevant security market. The pricing services also review prepayment speeds and other indicators, when applicable. As the significant inputs used in the pricing process for mortgage-backed securities are observable market inputs, the fair value of these securities are classified within Level 2. A small number of securities are included in Level 3 due to a low level of transparency on the inputs used in the pricing process.

•Municipal bonds — valuations provided by independent pricing services, with all prices provided through index providers and pricing vendors. The fair values of these securities are generally determined using spreads obtained from broker-dealers who trade in the relevant security market, trade prices and the new issue market. As the significant inputs used in the pricing process for municipal bonds are observable market inputs, the fair value of these securities are classified within Level 2.

•Commercial mortgage-backed securities — valuations provided by independent pricing services, substantially all through index providers and pricing vendors with a small amount through broker-dealers. The fair values of these securities are generally determined through the use of pricing models which use spreads to determine the appropriate average life of the securities. These spreads are generally obtained from the new issue market, secondary trading and from broker-dealers who trade in the relevant security market. The pricing services also review prepayment speeds and other indicators, when applicable. As the significant inputs used in the pricing process for commercial mortgage-backed securities are observable market inputs, the fair value of these securities are classified within Level 2.

•Non-U.S. government securities — valuations provided by independent pricing services, with all prices provided through index providers and pricing vendors. The fair values of these securities are generally based on international indices or valuation models which include daily observed yield curves, cross-currency basis index spreads and country credit spreads. As the significant inputs used in the pricing process for non-U.S. government securities are observable market inputs, the fair value of these securities are classified within Level 2.

•Asset-backed securities — valuations provided by independent pricing services, substantially all through index providers and pricing vendors with a small amount through broker-dealers. The fair values of these securities are generally determined through the use of pricing models (including Option

Other investments

The Company determined that exchange-traded investments in mutual funds would be included in Level 1 as their fair values are based on quoted market prices in active markets. Other investments also include term loan investments for which fair values are estimated by using quoted prices of term loan investments with similar characteristics, pricing models or matrix pricing. Such investments are generally classified within Level 2. The fair values for certain of the Company’s other investments are determined using net asset values as advised by external fund managers. The net asset value is based on the fund manager’s valuation of the underlying holdings in accordance with the fund’s governing documents. In accordance with applicable accounting guidance, certain investments that are measured at fair value using the net asset value per share (or its equivalent) practical expedient have not

been classified in the fair value hierarchy. A small number of securities are included in Level 3 due to the lack of an available independent price source for such securities. During the nine months ended September 30, 2019, the Company transferred $31.6 million of other investments from Level 2 to Level 3 based on a review of the pricing of such securities, as described above.

Derivative instruments

The Company’s futures contracts, foreign currency forward contracts, interest rate swaps and other derivatives trade in the over-the-counter derivative market. The Company uses the market approach valuation technique to estimate the fair value for these derivatives based on significant observable market inputs from third party pricing vendors, non-binding broker-dealer quotes and/or recent trading activity. As the significant inputs used in the pricing process for these derivative instruments are observable market inputs, the fair value of these securities are classified within Level 2.

Short-term investments

The Company determined that certain of its short-term investments held in highly liquid money market-type funds, Treasury bills and commercial paper would be included in Level 1 as their fair values are based on quoted market prices in active markets. The fair values of other short-term investments are generally determined using the spread above the risk-free yield curve and are classified within Level 2.

~~Contingent consideration liabilities~~

Contingent consideration liabilities (included in ‘other liabilities’ in the consolidated balance sheets) include amounts related to the acquisition of CMG Mortgage Insurance Company and its affiliated mortgage insurance companies and other acquisitions. Such amounts are remeasured at fair value at each balance sheet date with changes in fair value recognized in ‘net realized gains (losses).’ To determine the fair value of contingent consideration liabilities, the Company estimates future payments using an income approach based on modeled inputs which include a weighted average cost of capital. The Company determined that contingent consideration liabilities would be included within Level 3.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Financial Instruments Disclosed, But Not Carried, At Fair Value

The Company uses various financial instruments in the normal course of its business. The carrying values of cash, accrued investment income, receivable for securities sold, certain other assets, payable for securities purchased and certain other liabilities approximated their fair values at ~~September~~June 30, ~~2019,~~2020, due to their respective short maturities. As these financial instruments are not actively traded, their respective fair values are classified within Level 2.

At ~~September~~June 30, 2020, the Company’s senior notes were carried at their cost, net of debt issuance costs, of $2.86 billion and had a fair value of $3.49 billion. At December 31, 2019, the Company’s senior notes were carried at their cost, net of debt issuance costs, of $1.87 billion and had a fair value of ~~$2.35 billion. At December 31, 2018, the Company’s senior notes were carried at their cost, net of debt issuance costs, of $1.73 billion and had a fair value of $1.88~~$2.34 billion. The fair values of the senior notes were obtained from a third party pricing service and are based on observable market inputs. As such, the fair values of the senior notes are classified within Level 2.

8.9. Derivative Instruments

The Company’s investment strategy allows for the use of derivative instruments. The Company’s derivative instruments are recorded on its consolidated balance sheets at fair value. The Company utilizes exchange traded U.S. Treasury note, Eurodollar and other futures contracts and commodity futures to manage portfolio duration or replicate investment positions in its portfolios and the Company routinely utilizes foreign currency forward contracts, currency options, index futures contracts and other derivatives as part of its total return objective. In addition, certain of the Company’s investments are managed in portfolios which incorporate the use of foreign currency forward contracts which are intended to provide an economic hedge against foreign currency movements.

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

The following table summarizes information on the fair values and notional values of the Company’s derivative instruments:


	Estimated Fair Value							Estimated Fair Value

(2)	The fair value of asset derivatives are included in ‘other assets’ and the fair value of liability derivatives are included in ‘other liabilities.’


(3)	The fair value of TBAs are included in ‘fixed maturities available for sale, at fair value.’

The Company did not hold any derivatives which were designated as hedging instruments at ~~September~~June 30, ~~2019~~2020 or December 31, ~~2018.~~2019.

The Company’s derivative instruments can be traded under master netting agreements, which establish terms that apply to all derivative transactions with a counterparty. In the event of a bankruptcy or other stipulated event of default, such agreements provide that the non-defaulting party may elect to terminate all outstanding derivative transactions, in which case all individual derivative positions (loss or gain) with a counterparty are closed out and netted and replaced with a single amount, usually referred to as the termination amount, which is expressed in a single currency. The resulting single net amount, where positive, is payable to the party “in-the-money” regardless of whether or not it is the defaulting party, unless the parties have agreed that only the non-defaulting party is entitled to receive a termination payment where the net amount is positive and is in its favor. Contractual close-out netting reduces derivatives credit exposure from gross to net exposure. ~~The remaining derivatives included in the table above were not subject to a master netting agreement.~~

At ~~September~~June 30, ~~2019,~~2020, asset derivatives and liability derivatives of ~~$105.5~~$87.0 million and ~~$52.7~~$60.3 million, respectively, were subject to a master netting agreement, compared to ~~$80.4~~$97.8 million and ~~$18.9~~$37.8 million, respectively, at December 31, ~~2018.~~2019. The remaining derivatives included in the preceding table were not subject to a master netting agreement.

9.10. Commitments and Contingencies

Senior Notes

On June 30, 2020, Arch Capital completed a public offering of $1.0 billion aggregate principal amount of its 3.635% senior notes with a scheduled maturity of June 30, 2050 (the “2050 notes”). The 2050 notes are Arch Capital’s senior unsecured obligations and rank equally with all of its existing and future senior unsecured indebtedness. Interest payments on the 2050 notes are due semi-annually in arrears on June 30 and December 30, beginning on December 30, 2020, to holders of record on the preceding June 15 or December 15, as the case may be. Interest will be calculated on the basis of a 360-day year of twelve 30-day months. Subject to conditions of redemption, Arch Capital may redeem the 2050 notes at any time and from time to time prior to December 30, 2049, in whole or in part, at a redemption price equal to the “make-whole” redemption price, plus accrued and unpaid interest thereon to, but excluding, the redemption date. Arch Capital is planning to use the net proceeds for general corporate purposes.

Investment Commitments

The Company’s investment commitments, which are primarily related to agreements entered into by the Company to invest in funds and separately managed accounts when called upon, were approximately ~~$1.90~~$1.77 billion at ~~September~~June 30, ~~2019,~~2020, compared to ~~$1.77~~$1.69 billion at December 31, ~~2018.~~2019.

Interest Paid

Interest paid on the Company’s senior notes and other borrowings were $~~68.6~~57.4 million for the ~~nine~~six months ended ~~September~~June 30, ~~2019,~~2020, consistent with ~~$67.6~~$60.9 million for the ~~2018~~2019 period.

~~Letter of Credit and Revolving Credit Facilities~~

In September 2019, Watford entered into an unsecured letter of credit agreement. Watford has access to a $100 million letter of credit facility expiring on September 20, 2020. The Company does not guarantee or provide credit support for Watford, and the Company’s financial exposure to Watford is limited to its investment in Watford’s senior notes, common and preferred shares and counterparty credit risk (mitigated by collateral) arising from the reinsurance transactions.

~~10.~~11. Leases

In the ordinary course of business, the Company renews and enters into new leases for office property and equipment. At the lease inception date, the Company determines whether a contract contains a lease and its classification as a finance or operating lease. Primarily all of the Company’s leases are classified as operating leases. The Company’s operating leases have remaining lease terms of up to 11 years, some of which include options to extend the lease term. The Company considers these options when determining the lease term and measuring its lease liability and right-of-use asset. In addition, the Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants.

Short-term operating leases with an initial term of twelve months or less were excluded on the Company's consolidated balance sheet and represent an inconsequential amount of operating lease expense.

As most leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the lease commencement date in determining the present value of lease payments.

Additional information regarding the Company’s operating leases is as follows:

Bellemeade Re

The Company has entered into various aggregate excess of loss mortgage reinsurance agreements with various special purpose reinsurance companies domiciled in Bermuda (the “Bellemeade Agreements”). At the time the Bellemeade Agreements were entered into, the applicability of the accounting guidance that addresses VIEs was evaluated. As a result of the evaluation of the Bellemeade Agreements, the Company concluded that these entities are VIEs. However, given that the ceding insurers do not have the unilateral power to direct those activities that are significant to their economic performance, the Company does not consolidate such entities in its consolidated financial statements.

The following table presents the total assets of the Bellemeade entities, as well as the Company’s maximum exposure to loss associated with these VIEs, calculated as the maximum historical observable spread between the one month LIBOR, the basis for the contractual payments to bond holders, and short term invested trust asset yields.

ARCH CAPITAL GROUP LTD. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

14. Income Taxes

The Company’s income tax provision on income before income taxes resulted in an ~~expense~~effective tax rate of ~~8.5%~~12.5% for the ~~nine~~six months ended ~~September~~June 30, ~~2019,~~2020, compared to ~~an expense of 10.5%~~8.4% for the ~~2018~~2019 period.

The Company’s effective tax rate, which is based upon the expected annual effective tax rate, may fluctuate from period to period based on the relative mix of income or loss reported by jurisdiction and the varying tax rates in each jurisdiction. For interim reporting purposes, the Company has calculated its annual effective tax rate for the full year ~~of 2019~~2020 by treating excess tax benefits in the U.S. that arise from the accounting for stock based compensation as a discrete item. As such, this amount is not included when projecting the Company’s full year annual effective tax rate but rather is accounted for at the U.S. Federal statutory rate of 21% after applying the projected full year annual effective tax rate to actual nine months results before the discrete item. The impact of the discrete item resulted in a benefit of ~~0.4%~~0.5% for the ~~nine~~six months ended ~~September~~June 30, ~~2019.~~2020.

The Company had a net deferred tax ~~liability~~asset of ~~$55.9~~$9.3 million at ~~September~~June 30, ~~2019,~~2020, compared to a net deferred tax ~~asset~~liability of ~~$22.5~~$53.5 million at December 31, ~~2018.~~2019. The change is primarily a result of fluctuations in the ~~appreciation of the Company’s fixed maturities from December 31, 2018 to September 30, 2019.~~contingency reserve. In addition, the Company paid ~~$47.1~~$10.4 million and ~~recovered $34.0~~$43.5 million of income taxes for the ~~nine~~six months ended ~~September~~June 30, ~~2019~~2020 and ~~2018,~~2019, respectively.

15. Legal Proceedings

The Company, in common with the insurance industry in general, is subject to litigation and arbitration in the normal course of its business. As of ~~September~~June 30, ~~2019,~~2020, the Company was not a party to any litigation or arbitration which is expected by management to have a material adverse effect on the Company’s results of operations and financial condition and liquidity.

~~16. Subsequent Events~~

~~Bellemeade Re 2019-4 Ltd.~~

In October 2019, the Company’s first-lien U.S. mortgage insurance subsidiaries entered into an aggregate excess of loss reinsurance agreement with Bellemeade Re 2019-4 Ltd. (“Bellemeade 2019-4”), a special purpose reinsurance company domiciled in Bermuda. The Bellemeade 2019-4 agreement provides for up to $577.3 million of aggregate excess of loss reinsurance coverage at inception in excess of $162.4 million of aggregate losses for new delinquencies on a portfolio of in-force policies issued in the first half of 2019. The coverage

All of the proceeds paid to Bellemeade 2019-4 from the sale of the Notes were deposited into a reinsurance trust as security for Bellemeade 2019-4’s obligations. At all times, fundsacquire companies or reserve portfolios in the non-life property and casualty insurance and reinsurance ~~trust account are required~~run-off market.

~~Catastrophic Events~~

In the 2019 fourth quarter, Typhoon Hagibis, the ongoing wildfires in California and other catastrophic events may have an impact on the Company’s financial results. It is too early to reasonably estimate losses for these events given the significant uncertainties and the early stageBarbican Group Holdings Limited (“Barbican”), a wholly owned subsidiary of the ~~damage assessment process, among other factors.~~Company, entered into certain reinsurance and related transactions with Premia pursuant to which Premia assumed a transfer of liability for the 2018 and prior years of account of Barbican as of July 1, 2019. Barbicanrecorded reinsurance recoverable on unpaid and paid losses and funds held liability of $181.9 million and $169.0 million, respectively, at June 30, 2020, compared to $177.7 million and $180.0 million, respectively, at December 31, 2019.

ITEM 2.	MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following is a discussion and analysis of our financial condition and results of operations. This should be read in conjunction with our consolidated financial statements included in Item 1 of this report and also our Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in our Annual Report on Form 10-K for the year ended December 31, ~~2018~~2019 (“~~2018~~2019 Form 10-K”). In addition, readers should review “Risk Factors” set forth in Item 1A of Part I of our ~~2018~~2019 Form ~~10-K.~~10-K and “ITEM 1A—Risk Factors” of this Form 10-Q. Tabular amounts are in U.S. Dollars in thousands, except share amounts, unless otherwise noted.

Arch Capital Group Ltd. (“Arch Capital” and, together with its subsidiaries, “Arch”, “we” or “us”) is a Bermuda public limited liability company with approximately ~~$12.89~~$14.7 billion in capital at ~~September~~June 30, ~~2019~~2020 and, through operations in Bermuda, the United States, Europe, Canada, Australia and Hong Kong, writes insurance, reinsurance and mortgage insurance on a worldwide basis.

CURRENT OUTLOOK

Our objective is to achieve an average operating return on average equity of 15% or greater over the insurance cycle, which we believe to be an attractive return to our common shareholders given the risks we assume. We continue to look for opportunities to find acceptable books of business to underwrite without sacrificing underwriting discipline and continue to write a portion of our overall book in catastrophe-exposed business which has the potential to increase the volatility of our operating results. From an operating perspective, the 2020 second quarter reflected the benefits of rate improvements as all three of our underwriting segments are seeing attractive opportunities to grow at acceptable rates of return.

~~Across all lines~~Consequently, these rate improvements enabled us to expand writings in our ~~insurance business, renewal rates experienced a modest increase~~property casualty segments as ~~net premiums grew~~risk adjusted returns are increasingly achieved. We know from experience that this environment is an opportune time to significantly expand our participation into this hardening market. To support this growth, we raised an additional $1.0 billion of capital in the ~~2019 third quarter. Reinsurance pricing tends to follow that~~form of long-term senior notes at the end of the ~~primary insurance industry although catastrophe~~2020 second quarter.

COVID-19 has continued to significantly impact social and ~~large attritional~~economic activity in the U.S. and global markets. We are committed to the safety of our employees, including restricting travel and instituting an extensive work from home policy. These actions have helped prevent a major disruption to our clients and operations. The impact of the spread of COVID-19, a developing recession and related levels of unemployment has changed some of our outlook for 2020, but we are navigating this period with a strong capital base. The extent to which

COVID-19 impacts our business, results of operations and financial results depends on numerous evolving factors including, but not limited to: the magnitude and duration of COVID-19, the extent to which it will impact macroeconomic conditions, the speed of the anticipated recovery and governmental, business and individual reactions to the pandemic. Given the continuing evolution of the COVID-19 outbreak and the response to curb its spread, currently we are not able to estimate the future effects of the COVID-19 outbreak to our results of operations, financial condition, or liquidity.

For the 2020 second quarter and six months ended June 30, 2020, we recorded $173.1 million and $259.7 million, respectively, for COVID-19 losses across our property casualty segments. We continue to have limited information to accurately quantify our potential exposure to the pandemic in certain areas but have established IBNR reserves for occurrences based on policy terms and conditions including limits, sub-limits, and deductibles. These reserves were recorded across a number of lines of business, such as trade credit, travel, workers compensation and property where we have limited exposure to policies that do not contain a specific pandemic exclusion and/or explicitly afford business interruption coverage under a pandemic. Given the ~~Japanese typhoons this year,~~unusual circumstances and breadth of the pandemic, we have classified COVID-19 losses as a catastrophe.

For our U.S. primary mortgage operations, reported delinquencies were 5.14% at June 30, 2020, compared to 1.42% at March 31, 2020 and came in better than our expectations last quarter at the ~~reinsurance market can disproportionately affect results and create opportunities.~~beginning of the COVID-19 pandemic. We believe that ~~property facultative~~the mortgage insurance industry is benefiting from solid credit quality of loan originations in the years after the 2008 Great Financial Crisis, a favorable supply and ~~marine businesses~~demand imbalance in housing and strong and swift government intervention. As a result, we are ~~examples~~seeing better than expected delinquency rates emerging this quarter even as delinquency rates are at elevated levels, reflecting the impact of ~~improving markets.~~the recession and forbearance programs under the CARES Act to borrowers experiencing a hardship during COVID-19. Forbearance allows for mortgage payments to be suspended for up to 360 days along with a suspension of foreclosures and evictions. Our current view equates to a claim rate slightly above 5% primarily as a result of forbearances on newly reported delinquencies. While this claim rate is significantly higher than rates we experienced under other catastrophic events such as forbearance programs related to hurricanes, it is also lower than what the industry experienced in the 2008 Great Financial Crisis. See “Results of Operations—Mortgage Segment” for further details on our mortgage operations.

~~Our underwriting teams continue~~



ARCH CAPITAL	44	2020 SECOND QUARTER FORM 10-Q

Table of Contents

Record mortgage originations fueled by low mortgage rates are creating surges in both refinancing and purchase activity. This favorable financing environment is supporting home prices which we currently estimate to ~~execute~~be rising around 5% annually across the U.S. The early indicators for housing and mortgage insurance specifically bode well for a ~~disciplined strategy by emphasizing small~~better outcome than we expected at the end of the 2020 first quarter. However, there remains significant uncertainty on the path of this recession and ~~medium-sized accounts~~caution is warranted on predicting how this will ultimately affect our results of operations.

We expect that delinquency rates may increase progressively from the current level, as more borrowers request forbearance on their mortgage loans under the CARES Act. We expect to record loss reserves on these delinquencies, which will likely result in elevated levels of incurred losses over ~~large accounts, shrinking premiums in more commoditized lines such~~the coming quarters. Over time, we would expect many of these delinquencies to cure and revert back to performing loans as ~~general liability~~the economy returns to a less-stressed state. At this time, we do not have enough visibility to predictably forecast the rate at which forbearance delinquencies will be reported to us, cure or ultimately turn into claims on an annual, let alone a quarterly basis. That said, based on our current analysis which tells us that the pandemic will represent an earnings event for our mortgage segment and ~~by utilizing reinsurance purchases to reduce volatility on large account, high capacity business. The spread between rate changes and loss trend~~not a capital event, our current expectation continues to be ~~a key variable in assessing expected returns and can be difficult to quantify precisely, particularly in specialty lines.~~

For further discussion of the ~~general economy remain strong. Our results continue to reflect our success in making high quality credit underwriting risk decisions and building customer relationships.~~potential impacts of COVID-19, see “ITEM 1A—Risk Factors”.

Arch remains committed to providing solutions across many offerings as the marketplace evolves, including the mortgage credit risk transfer programs initiated by government sponsored enterprises, or ~~“GSEs,~~“GSEs.” ~~in 2018.~~ Such programs have continued to generate business. In addition, we completed Bellemeade risk ~~transfers~~transfer in ~~March, April, July and October 2019,~~June 2020, increasing our protection for mortgage tail risk. The Bellemeade structures provide approximately $3.1 billion of aggregate reinsurance coverage as of June 30, 2020.

FINANCIAL MEASURES

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

Book Value per Share

Book value per share represents total common shareholders’ equity available to Arch divided by the number of common shares outstanding. Management uses growth in book value per share as a key measure of the value generated for our common shareholders each period and believes that book value per share

is the key driver of Arch Capital’s share price over time. Book value per share is impacted by, among other factors, our underwriting results, investment returns and share repurchase activity, which has an accretive or dilutive impact on book value per share depending on the purchase price.

Book value per share was ~~$25.61~~$27.62 at ~~September~~June 30, ~~2019,~~2020, compared to $26.10 at March 31, 2020 and $24.64 at June 30, ~~2019 and $21.15 at September 30, 2018.~~2019. The ~~3.9%~~5.8% increase for the ~~2019 third~~2020 second quarter reflected ~~strong underwriting results and~~ the impact of ~~a decrease in interest rates~~total return on ~~our fixed income securities~~investments, partially offset by the impact of COVID-19 on underwriting results, while the ~~21.1%~~12.1% increase over the trailing twelve months reflected strong underwriting results and investment returns.

Operating Return on Average Common Equity

Operating return on average common equity (“Operating ROAE”) represents annualized after-tax operating income available to Arch common shareholders divided by the average of beginning and ending common shareholders’ equity available to Arch during the period. After-tax operating income available to Arch common shareholders, a non-GAAP financial

measure as defined in Regulation G, represents net income available to Arch common shareholders, excluding net realized gains or losses (which includes changes in the allowance for credit losses on financial assets and net impairment losses recognized in ~~earnings,~~earnings) equity in net income or loss of investment funds accounted for using the equity method, net foreign exchange gains or losses, transaction costs and other ~~loss on redemption of preferred shares~~ and income taxes. Management uses Operating ROAE as a key measure of the return generated to common shareholders. See “Comment on Non-GAAP Financial Measures.”

Our Operating ROAE was ~~10.3%~~0.6% for the 2020 second quarter, compared to 13.1% for the 2019 ~~third~~second quarter, and 3.8% for six months ended June 30, 2020, compared to ~~11.4%~~12.7% for the ~~2018 third quarter, and 12.0% for the nine months ended September 30,~~ 2019 ~~compared to 11.4% for the 2018~~ period. The ~~2019 and 2018~~lower 2020 returns reflected ~~favorable mortgage insurance~~the impact of COVID-19 on underwriting ~~performance, strong~~results and lower investment ~~returns and a low level of catastrophic activity.~~income than in the 2019 periods.

Total Return on Investments

Total return on investments includes investment income, equity in net income or loss of investment funds accounted for using the equity method, net realized gains and losses (excluding changes in the allowance for credit losses on non-investment related financial assets) and the change in unrealized gains and losses generated by Arch’s investment portfolio. Total return is calculated on a pre-tax basis and before investment expenses, excludes amounts reflected in the ‘other’ segment, and reflects the effect of financial market conditions along with foreign currency fluctuations. In addition, total return incorporates the timing of investment returns during the periods. The following table summarizes our total return compared to the benchmark return against which we measured our portfolio during the periods. See “Comment on Non-GAAP Financial Measures.”

The benchmark return index is a customized combination of indices intended to approximate a target portfolio by asset mix and average credit quality while also matching the approximate estimated duration and currency mix of our insurance and reinsurance liabilities. Although the estimated duration and average credit quality of this index will move as the duration and rating of its constituent securities change, generally we do

not adjust the composition of the benchmark return index except to incorporate changes to the mix of liability currencies and durations noted above. The benchmark return index should not be interpreted as expressing a preference for or aversion to any particular sector or sector weight. The index is intended solely to provide, unlike many master indices that change based on the size of their constituent indices, a relatively stable basket of investable indices. At ~~September~~June 30, ~~2019,~~2020, the benchmark return index had an average credit quality of “Aa3” by Moody’s Investors Service (“Moody’s”), and an estimated duration of ~~2.97~~3.04 years.

COMMENT ON NON-GAAP FINANCIAL MEASURES

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



~~ARCH CAPITAL~~	50	~~2019 THIRD QUARTER FORM 10-Q~~

~~Table of Contents~~

of after-tax operating income available to Arch common shareholders and annualized operating return on average common equity are non-GAAP financial measures as defined in Regulation G. The reconciliation of such measures to net income available to Arch common shareholders and annualized return on average common equity (the most directly comparable GAAP financial

Table of Contents

measures) in accordance with Regulation G is included under “Results of Operations” below.

We believe that net realized gains or losses, ~~net impairment losses recognized in earnings,~~ equity in net income or loss of investment funds accounted for using the equity method, net foreign exchange gains or losses and transaction costs and other ~~and loss on redemption of preferred shares~~ in any particular period are not indicative of the performance of, or trends in, our business. Although net realized gains or losses, ~~net impairment losses recognized in earnings,~~ equity in net income or loss of investment funds accounted for using the equity method and net foreign exchange gains or losses are an integral part of our operations, the decision to realize investment gains or losses, the recognition of the change in the carrying value of investments accounted for using the fair value option in net realized gains or losses, the recognition of net impairment losses, the recognition of equity in net income or loss of investment funds accounted for using the equity method and the recognition of foreign exchange gains or losses are independent of the insurance underwriting process and result, in large part, from general economic and financial market conditions. Furthermore, certain users of our financial information believe that, for many companies, the timing of the realization of investment gains or losses is largely opportunistic. In addition, changes in the allowance for credit losses and net impairment losses recognized in earnings on ~~our~~the Company’s investments represent other-than-temporary declines in expected recovery values on securities without actual realization. The use of the equity method on certain of our investments in certain funds that invest in fixed maturity securities is driven by the ownership structure of such funds (either limited partnerships or limited liability companies). In applying the equity method, these investments are initially recorded at cost and are subsequently adjusted based on our proportionate share of the net income or loss of the funds (which include changes in the market value of the underlying securities in the funds). This method of accounting is different from the way we account for our other fixed maturity securities and the timing of the recognition of equity in net income or loss of investment funds accounted for using the equity method may differ from gains or losses in the future upon sale or maturity of such investments. Transaction costs and other include advisory, financing, legal, severance, incentive compensation and other transaction costs related to acquisitions. We believe that transaction costs and other, due to their non-recurring nature, are not indicative of the performance of, or trends in, our business performance. ~~The loss on redemption of preferred shares related to the redemption of our Series C preferred shares in January 2018 and had no impact on shareholders' equity or cash flows.~~ Due to these reasons, we exclude net realized gains

or losses, ~~net impairment losses recognized in earnings,~~ equity in net income or loss of investment funds accounted for using the equity method, net foreign exchange gains or losses and transaction costs and other ~~and loss on redemption of preferred shares~~ from the calculation of after-tax operating income available to Arch common shareholders.

We believe that showing net income available to Arch common shareholders exclusive of the items referred to above reflects the underlying fundamentals of our business since we evaluate the performance of and manage our business to produce an underwriting profit. In addition to presenting net income

available to Arch common shareholders, we believe that this presentation enables investors and other users of our financial information to analyze our performance in a manner similar to how management analyzes performance. We also believe that this measure follows industry practice and, therefore, allows the users of financial information to compare our performance with our industry peer group. We believe that the equity analysts and certain rating agencies which follow us and the insurance industry as a whole generally exclude these items from their analyses for the same reasons.

Our segment information includes the presentation of consolidated underwriting income or loss and a subtotal of underwriting income or loss before the contribution from the ‘other’ segment. Such measures represent the pre-tax profitability of our underwriting operations and include net premiums earned plus other underwriting income, less losses and loss adjustment expenses, acquisition expenses and other operating expenses. Other operating expenses include those operating expenses that are incremental and/or directly attributable to our individual underwriting operations. Underwriting income or loss does not incorporate items included in our corporate (non-underwriting) segment. While these measures are presented in note 4, “Segment Information,” of the notes accompanying our consolidated financial statements, they are considered non-GAAP financial measures when presented elsewhere on a consolidated basis. The reconciliations of underwriting income or loss to income before income taxes (the most directly comparable GAAP financial measure) on a consolidated basis and a subtotal before the contribution from the ‘other’ segment, in accordance with Regulation G, is shown in note 4, “Segment Information” to our consolidated financial statements.

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

Along with consolidated underwriting income, we provide a subtotal of underwriting income or loss before the contribution

from the ‘other’ segment. The ‘other’ segment includes the results of Watford Holdings Ltd. Watford Holdings Ltd. is the parent of Watford Re Ltd., a multi-line Bermuda reinsurance company (together with Watford Holdings Ltd., “Watford”). Pursuant to generally accepted accounting principles, Watford is considered a variable interest entity and we concluded that we are the primary beneficiary of Watford. As such, we consolidate the results of Watford in our consolidated financial statements, although we only own approximately ~~11%~~13% of Watford’s common equity. Watford’s own management and board of directors are responsible for its results and profitability. In addition, we do not guarantee or provide credit support for

Watford. Since Watford is an independent company, the assets of Watford can be used only to settle obligations of Watford and Watford is solely responsible for its own liabilities and commitments. Our financial exposure to Watford is limited to our investment in Watford’s senior notes, common and preferred shares and counterparty credit risk (mitigated by collateral) arising from the reinsurance transactions. We believe that presenting certain information excluding the ‘other’ segment enables investors and other users of our financial information to analyze our performance in a manner similar to how our management analyzes performance.

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

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

RESULTS OF OPERATIONS

The following table summarizes our consolidated financial data, including a reconciliation of net income or loss available to Arch common shareholders to after-tax operating income or loss available to Arch common shareholders. Each line item reflects the impact of our ~~approximate 11%~~percentage ownership of Watford’s common ~~equity.~~equity during such period.

Segment Information

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

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

The insurance segment’s net favorable development was ~~$4.4~~$2.5 million, or ~~0.7~~0.4 points, for the 2020 second quarter, compared to $2.6 million, or 0.4 points, for the 2019 ~~third~~second quarter, ~~compared to $5.9~~and $3.6 million, or ~~1.1~~0.3 points, for the ~~2018 third quarter, and $11.4~~six months ended June 30, 2020, compared to $7.0 million, or ~~0.7~~0.6 points, for the ~~nine months ended September 30,~~ 2019 ~~compared to $14.1 million, or 0.9 points, for the 2018~~ period. ~~The 2019 third quarter loss ratio reflected a lower level of large attritional losses than in the 2018 third quarter.~~ See note 5, “Reserve for Losses and Loss Adjustment Expenses,” to our consolidated financial statements for information about the insurance segment’s prior year reserve development.

Underwriting Expenses.

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

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

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

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

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

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

flood and earthquake. Business is assumed on both a proportional and excess of loss treaty basis and on a facultative 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.

The mortgage segment’s current year loss ratio was ~~2.6~~47.5 points ~~lower~~higher in the ~~2019 third~~2020 second quarter than in the ~~2018 third~~2019 second quarter.

The percentage of loans in default on U.S. primary mortgage business was 5.14% at June 30, 2020, compared to 1.45% at June 30, 2019. For U.S. primary mortgage insurance, loss reserving under GAAP is based on reported delinquencies.

As this exercise cannot be performed accurately, the Company is not reporting COVID-19 provisions separately from its overall loss provisions.

Such expenses are primarily related to the UGC acquisition ~~while the 2019 periods also included amortization related~~and other acquisitions in late 2018 to ~~the previously announced acquisitions of (i) renewal rights of a U.K. commercial lines book of business on January 1, 2019; and (ii) McNeil & Co. on December 6, 2018.~~2019. See the consolidated financial statements contained in our ~~2018~~2019 Form 10-K for disclosures on our amortization pattern.

Interest Expense.

Interest expense was ~~$23.2~~$25.1 million for the 2020 second quarter, compared to the $23.4 million for the 2019 ~~third~~second quarter ~~compared to the $24.7~~and $50.4 million for the ~~2018 third quarter, and $70.1~~six months ended June 30, 2020, compared to $46.9 million for the ~~nine months ended September 30,~~ 2019 ~~compared to $76.6 million for the 2018~~ period. The ~~lower level~~increase in the ~~2019 periods~~2020 period reflected ~~the paydown of revolving credit agreement borrowings~~an increase in ~~the~~funds held liabilities. The second half of ~~2018.~~

~~Loss on Redemption~~2020 will reflect interest expense of ~~Preferred Shares.~~

~~In January 2018, we redeemed all remaining 6.75% Series C preferred shares and, in accordance with GAAP, recorded a loss of $2.7~~$18.3 million ~~to remove original issuance costs~~ related to the ~~redeemed shares from additional paid-in capital. Such adjustment had no impact~~$1.0 billion of new senior notes issued on ~~total shareholders’ equity or cash flows.~~June 30, 2020.

Net Realized Gains or Losses.

We recorded net realized gains of ~~$81.2~~$385.1 million for the ~~2019 third~~2020 second quarter, compared to net realized ~~losses~~gains of ~~$47.0~~$125.1 million for the ~~2018 third~~2019 second quarter, and net realized gains of ~~$318.7~~$313.0 million for the ~~nine~~six months ended ~~September~~June 30, ~~2019,~~2020, compared to net realized ~~losses~~gains of ~~$218.4~~$236.2 million for the ~~2018~~2019 period. Currently, our portfolio is actively managed to maximize total return within certain guidelines. The effect of financial market movements on the investment portfolio will directly impact net realized gains and losses as the portfolio is adjusted and

rebalanced. Net realized gains or losses from the sale of fixed maturities primarily results from our decisions to reduce credit exposure, to change duration targets, to rebalance our portfolios or due to relative value determinations.

Net realized gains or losses also include realized and unrealized contract gains and losses on our derivative instruments, changes in the fair value of assets accounted for using the fair value option and in the fair value of equities, along with ~~re-measurement of contingent consideration liability amounts.~~changes in the allowance for credit losses on financial assets and net impairment losses recognized in earnings. See note 6,7, “Investment Information—Net Realized Gains (Losses),” to our consolidated financial statements for additional information.

~~Net Impairment Losses Recognized in Earnings.~~

We recorded $1.2 million of impairment losses for the 2019 third quarter, compared to $0.5 million for the 2018 third quarter, and $2.5 million for the nine months ended September 30, 2019, compared to $1.1 million for the 2018 period. See note 6,7, “Investment Information—~~Other-Than-Temporary Impairments,~~Allowance for Credit Losses,” to our consolidated financial statements for additional information.

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

We recorded ~~$17.1~~a loss of $65.1 million offor equity in net income or loss related to investment funds accounted for using the equity method in the ~~2019 third~~2020 second quarter, compared to ~~$16.0~~$32.5 million of income for the ~~2018 third~~2019 second quarter, and ~~$96.5~~a loss of $69.3 million for the six months ended June 30, 2020, compared to $79.4 million of income for the ~~nine months ended September 30,~~ 2019 ~~compared~~period. Such investments are generally recorded on a one to ~~$52.5 million for~~three month lag based on the ~~2018 period.~~availability of reports from the investment funds. Investment funds accounted for using the equity method totaled ~~$1.58~~$1.73 billion at ~~September~~June 30, ~~2019,~~2020, compared to ~~$1.49~~$1.66 billion at December 31, ~~2018.~~2019.

Net Foreign Exchange Gains or Losses.

Net foreign exchange ~~gains~~losses for the ~~2019 third~~2020 second quarter were ~~$29.8~~$42.4 million, compared to net foreign exchange ~~gains~~losses for the ~~2018 third~~2019 second quarter of ~~$7.1~~$6.2 million.

Amounts in both periods were primarily unrealized and resulted from the effects of revaluing our net insurance liabilities required to be settled in foreign currencies at each balance sheet date.

Income Tax Expense.

Our income tax provision on income (loss) before income taxes resulted in an expense of ~~8.9%~~8.8% for the 2020 second quarter, compared to 8.7% for the 2019 ~~third~~second quarter and 10.7% for the six months ended June 30, 2020, compared to 9.0% for the ~~nine months ended September 30,~~ 2019 ~~compared to 12.9% for~~period.

Bellemeade Re

We have entered into various aggregate excess of loss mortgage reinsurance agreements with various special purpose reinsurance companies domiciled in Bermuda (the “Bellemeade Agreements”). For the respective coverage periods, we will retain the first layer of the respective aggregate losses and the special purpose reinsurance companies will provide second layer coverage up to the outstanding coverage amount. We will then retain losses in excess of the outstanding coverage limit. The aggregate excess of loss reinsurance coverage generally decreases over a ten-year period as the underlying covered mortgages ~~amortize.~~amortize, unless provisional call options embedded within certain of the Bellemeade Agreements are executed or if pre-defined delinquency triggering events occur.

The following table summarizes the respective coverages and retentions at ~~September~~June 30, ~~2019:~~2020:

Reserve for Losses and Loss Adjustment Expenses

We establish reserve for losses and loss adjustment expenses (“Loss Reserves”) which represent estimates involving



ARCH CAPITAL	61	2020 SECOND QUARTER FORM 10-Q

Table of Contents

actuarial and statistical projections, at a given point in time, of our expectations of the ultimate settlement and administration costs of losses incurred. Estimating Loss Reserves is inherently difficult, which is exacerbated by the fact that we have relatively limited historical experience upon which to base such estimates. We utilize actuarial models as well as available historical insurance industry loss ratio experience and loss development patterns to assist in the establishment of Loss Reserves. Actual losses and loss adjustment expenses paid will deviate, perhaps substantially, from the reserve estimates reflected in our financial statements.

At ~~September~~June 30, ~~2019~~2020 and December 31, ~~2018,~~2019, our Loss Reserves, net of unpaid losses and loss adjustment expenses recoverable, by type and by operating segment were as follows:

LIQUIDITY

Our liquidity and capital resources were not materially impacted by COVID-19 during the second quarter of 2020. For further discussion of the risks related to our potential future impacts of COVID-19 on our liquidity and capital resources, see “ITEM 1A—Risk Factors”.

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

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

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

For the ~~nine~~six months ended ~~September~~June 30, ~~2019,~~2020, Arch Capital received dividends of ~~$86.4~~$143.0 million from Arch Re Bermuda, our Bermuda-based reinsurer and insurer, which can pay approximately ~~$2.54~~$2.96 billion to Arch Capital during the remainder of ~~2019~~2020 without providing an affidavit to the Bermuda Monetary Authority (“BMA”). ~~For the nine months ended September 30, 2019 Arch Capital Group (U.S.) Inc. (“Arch-U.S.”) received $465.0 million of dividends from Arch U.S. MI Holdings Inc., a subsidiary of Arch-U.S.~~

We expect that our liquidity needs, including our anticipated (re)insurance obligations and operating and capital expenditure needs, for the next twelve months, ~~at a minimum,~~ will be met by funds generated from underwriting activities and investment income,

SHARE REPURCHASE PROGRAM

The board of directors of Arch Capital has authorized the investment in Arch Capital’s common shares through a share repurchase program. For the ~~nine~~six months ended ~~September~~June 30, ~~2019,~~2020, Arch Capital repurchased ~~0.1~~2.6 million shares under the share repurchase program with an aggregate purchase price of ~~$2.9~~$75.5 million. Since the inception of the share repurchase program through ~~September~~June 30, ~~2019,~~2020, Arch Capital has repurchased ~~386.3~~388.9 million common shares for an aggregate purchase price of ~~$3.97~~$4.04 billion. At ~~September~~June 30, ~~2019,~~2020, approximately ~~$160.9~~$924.5 million of share repurchases were available under the ~~program. On November 8, 2019, the board of directors of ACGL increased the aggregate purchase amount authorized under the share repurchase~~ program, ~~to $1.0 billion. Repurchases under this authorization~~which may be effected from time to time in open market or privately negotiated transactions through December 31, 2021. The timing and amount of the repurchase transactions under this program will depend on a variety of factors, including market conditions and corporate and regulatory considerations. ~~We will continue to monitor our share price and, depending~~Depending upon results of operations, market conditions and the development of the economy, as well as other factors, generally we will consider share repurchases on an opportunistic ~~basis.~~basis from time to time. During the 2020 second quarter, we have not repurchased any shares under our share repurchase program and we do not expect to repurchase any shares for the remainder of 2020.

CATASTROPHIC EVENTS AND SEVERE ECONOMIC EVENTS

We have large aggregate exposures to natural and man-made catastrophic events, pandemic events like COVID-19 and severe economic events. ~~Catastrophes~~Natural catastrophes can be caused by various events, including hurricanes, floods, windstorms, earthquakes, hailstorms, tornadoes, explosions,

severe winter weather, fires, droughts and other natural disasters. Man-made catastrophic events may include acts of war, acts of terrorism and political instability. Catastrophes can also cause losses in non-property business such as mortgage insurance, workers’ compensation or general liability. In addition to the nature of property business, we believe that economic and geographic trends affecting insured property, including inflation, property value appreciation and geographic concentration, tend to generally increase the size of losses from catastrophic events over time.

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~~tangible shareholders’ equity available to ~~Arch.~~Arch (total shareholders’ equity available to Arch less goodwill and intangible assets). We reserve the right to change this threshold at any time.

Based on in-force exposure estimated as of ~~October~~July 1, ~~2019,~~2020, our modeled peak zone catastrophe exposure was a windstorm affecting the ~~Northeastern U.S.,~~Florida Tri-County, with a net probable maximum pre-tax loss of ~~$414~~$832 million, followed by windstorms affecting ~~Florida Tri-County~~Northeastern U.S. and the Gulf of Mexico regions with net probable maximum pre-tax losses of ~~$398 million~~$658 and ~~$357~~$621 million, respectively. Our exposures to other perils, such as U.S. earthquake and international events, were less than the exposures arising from U.S. windstorms and hurricanes. As of ~~October~~July 1, ~~2019,~~2020, our modeled peak zone earthquake exposure (San Francisco earthquake) represented approximately ~~70%~~58% of our peak zone catastrophe exposure, and our modeled peak zone international exposure (Japan earthquake) was substantially less than both our peak zone windstorm and earthquake exposures.

Effective July 1, ~~2019,~~2020, our insurance operations had in effect a reinsurance program which provided coverage for certain property-catastrophe related losses equal to ~~$275~~$243 million in excess of various retentions per occurrence.

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

~~Table of Contents~~

Currently, we seek to limit our modeled RDS loss from a severe economic event to approximately 25% of ~~total~~ tangible shareholders’ equity available to ~~Arch (total shareholders’ equity available to Arch less goodwill and intangible assets).~~Arch. We reserve the right to change this threshold at any time. Based on in-force exposure estimated as of ~~October~~July 1, ~~2019,~~2020, our modeled RDS loss was approximately 9%8% of tangible shareholders’ equity available to Arch.

Net probable maximum loss estimates are net of expected reinsurance recoveries, before income tax and before excess reinsurance reinstatement premiums. RDS loss estimates are net of expected reinsurance recoveries and ~~after~~before income tax. Catastrophe loss estimates are reflective of the zone indicated and not the entire portfolio. Since hurricanes and windstorms can affect more than one zone and make multiple landfalls, our catastrophe loss estimates include clash estimates from other zones. Our catastrophe loss estimates and RDS loss estimates do not represent our maximum exposures and it is highly likely that our actual incurred losses would vary materially from the modeled estimates. There can be no assurances that we will not suffer pre-tax losses greater than 25% of our ~~total shareholders' equity or~~ tangible

These factors ~~including~~include the inherent uncertainties in estimating the frequency and severity of such events and the margin of error in making such determinations resulting from potential inaccuracies and inadequacies in the data provided by clients and brokers, the modeling techniques and the application of such techniques or as a result of a decision to change the percentage of shareholders' equity exposed to a single catastrophic event or severe economic event. In addition, actual losses may increase if our reinsurers fail to meet their obligations to us or the reinsurance protections purchased by us are exhausted or are otherwise unavailable.

MARKET SENSITIVE INSTRUMENTS AND RISK MANAGEMENT

In accordance with the SEC’s Financial Reporting Release No. 48, we performed a sensitivity analysis to determine the effects that market risk exposures could have on the future earnings, fair values or cash flows of our financial instruments as of ~~September~~June 30, ~~2019.~~2020. Market risk represents the risk of changes in the fair value of a financial instrument and is comprised of

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

An analysis of material changes in market risk exposures at ~~September~~June 30, ~~2019~~2020 that affect the quantitative and qualitative disclosures presented in our ~~2018~~2019 Form 10-K (see section captioned “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Market Sensitive Instruments and Risk Management”) were as follows:

Investment Market Risk

Fixed Income Securities. We invest in interest rate sensitive securities, primarily debt securities. We consider the effect of interest rate movements on the fair value of our fixed maturities, fixed maturities pledged under securities lending agreements, short-term investments and certain of our other investments, equity securities and investment funds accounted for using the

equity method which invest in fixed income securities (collectively, “Fixed Income Securities”) and the corresponding change in unrealized appreciation. As interest rates rise, the fair value of our ~~interest rate sensitive securities~~Fixed Income Securities falls, and the converse is also true. Based on historical observations, there is a low probability that all interest rate yield curves would shift in the same direction at the same time. Furthermore, at times interest rate movements in certain credit sectors exhibit a much lower correlation to changes in U.S. Treasury yields. Accordingly, the actual effect of interest rate movements may differ materially from the amounts set forth in the following tables.

The following table summarizes the effect that an immediate, parallel shift in the interest rate yield curve would have had on our ~~fixed income securities:~~Fixed Income Securities:

As credit spreads widen, the fair value of our ~~fixed income securities~~Fixed Income Securities falls, and the converse is also true.

Another method that attempts to measure portfolio risk is Value-at-Risk (“VaR”). VaR ~~attempts to take into account a broad cross-section of risks facing a portfolio by utilizing relevant securities volatility data skewed towards the most recent months and quarters. VaR~~ measures the ~~amount of a portfolio at risk for outcomes 1.65 standard deviations from the mean based on~~worst expected loss under normal market conditions over a ~~one year~~specific time ~~horizon and is expressed as~~interval at a ~~percentage of the portfolio’s initial value. In other words,~~given confidence level. The 1-year 95th percentile parametric VaR reported herein estimates that 95% of the time, ~~should~~ the ~~risks taken into account in the VaR model perform per their historical tendencies, the portfolio’s~~portfolio loss in ~~any one year period is expected to~~a one-year horizon would be less than or equal to the calculated ~~VaR,~~number, stated as a percentage of the measured portfolio’s initial value. The VaR is a variance-covariance based estimate, based on linear sensitivities of a portfolio to a broad set of systematic market risk factors and idiosyncratic risk factors mapped to the portfolio exposures. The relationships between the risk factors are estimated using historical data, and the most recent data points are generally given more weight. As of ~~September~~June 30, ~~2019,~~2020, our portfolio’s VaR was estimated to be ~~3.34%~~10.1% compared to an estimated ~~3.02%~~3.19% at December 31, ~~2018.~~2019. In periods where the volatility of the risk factors mapped to our portfolio’s exposures is higher due to market conditions, the resulting VaR is higher than in other periods.

Equity Securities. At ~~September~~June 30, ~~2019~~2020 and December 31, ~~2018,~~2019, the fair value of our investments in equity securities (excluding securities included in Fixed Income Securities above) totaled ~~$559.1~~$814.4 million and ~~$368.8~~$827.8 million, respectively. These investments are exposed to price risk, which is the potential loss arising from decreases in fair value. An immediate hypothetical 10% decline in the value of each position would reduce the fair value of such investments by approximately ~~$55.9~~$81.4 million and ~~$36.9~~$82.8 million at ~~September~~June 30, ~~2019~~2020 and December 31, ~~2018,~~2019, respectively, and would have decreased book value per share by approximately ~~$0.14~~$0.20 and ~~$0.09,~~$0.20, respectively. An immediate hypothetical 10% increase in the value of each position would increase the fair value of such investments by approximately ~~$55.9~~$81.4 million and ~~$36.9~~$82.8 million at ~~September~~June 30, ~~2019~~2020 and December 31, ~~2018,~~2019, respectively, and would have increased book value per share by approximately ~~$0.14~~$0.20 and ~~$0.09,~~$0.20, respectively.

Investment-Related Derivatives. At ~~September~~June 30, ~~2019,~~2020, the notional value of all derivative instruments (excluding to-be-announced mortgage backed securities which are included in the fixed income securities analysis above and foreign currency forward contracts which are included in the foreign currency exchange risk analysis below) was ~~$7.53~~$5.66 billion, compared to ~~$4.95~~$8.04 billion at December 31, ~~2018.~~2019. If the underlying exposure of each investment-related derivative held at ~~September~~June 30, ~~2019~~2020 depreciated by 100 basis points, it would have resulted in a reduction in net income of approximately ~~$75.3~~$56.6 million, and a decrease in book value per share of approximately ~~$0.19~~$0.14 per share, compared to ~~$49.5~~$80.4 million and ~~$0.12~~$0.20 per share, respectively, on investment-related derivatives held at December 31, ~~2018.~~2019. If the underlying exposure of each investment-related derivative held at ~~September~~June 30, ~~2019~~2020 appreciated by 100 basis points, it would have resulted in an increase in net income of approximately ~~$75.3~~$56.6 million, and an increase in book value per share of approximately ~~$0.19~~$0.14 per share, compared to ~~$49.5~~$80.4 million and ~~$0.12~~$0.20 per share, respectively, on ~~investment-related~~investment-

related derivatives held at December 31, ~~2018.~~2019. See note 8,9, “Derivative Instruments,” to our consolidated financial statements for additional disclosures concerning derivatives.

Foreign Currency Exchange Risk

Foreign currency rate risk is the potential change in value, income and cash flow arising from adverse changes in foreign currency exchange rates. Through our subsidiaries and branches located in various foreign countries, we conduct our insurance and reinsurance operations in a variety of local currencies other than the U.S. Dollar. We generally hold investments in foreign currencies which are intended to mitigate our exposure to foreign currency fluctuations in our net insurance liabilities. We may also utilize foreign currency forward contracts and currency options as part of our investment strategy. See note 8,9, “Derivative Instruments,” to our consolidated financial statements for additional information.

For further discussion on foreign exchange activity, please refer to ~~“—Results~~“Results of Operations.”

Effects of Inflation

We do not believe that inflation has had a material effect on our consolidated results of operations, except insofar as inflation may affect our reserve for losses and loss adjustment expenses and interest rates. The potential exists, after a catastrophe loss or pandemic events like COVID-19, for the development of inflationary pressures in a local economy. The anticipated effects of inflation on us are considered in our catastrophe loss models. The actual effects of inflation on our results cannot be accurately known until claims are ultimately settled.

OTHER FINANCIAL INFORMATION

The consolidated financial statements as of ~~September~~June 30, ~~2019~~2020 and for the three month and ~~nine~~six month periods ended ~~September~~June 30, ~~2019~~2020 and ~~2018~~2019 have been reviewed by PricewaterhouseCoopers LLP, the registrant's independent public accountants, whose report is included as an exhibit to this filing. The report of PricewaterhouseCoopers LLP states that they did not audit and they do not express an opinion on that unaudited financial information. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied. PricewaterhouseCoopers LLP is not subject to the liability provisions of Section 11 of the Securities Act of 1933 for their report on the unaudited financial information because that report is not a "report" or a "part" of the registration statement prepared or certified by PricewaterhouseCoopers LLP within the meaning of Sections 7 and 11 of the Securities Act of 1933.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

In connection with the filing of this Form 10-Q, our management, including the Chief Executive Officer and Chief Financial Officer, conducted an evaluation of the effectiveness of disclosure controls and procedures pursuant to applicable Exchange Act Rules as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the disclosure controls and procedures were effective as of the end of and during the period covered by this report with respect to information being recorded, processed, summarized and reported within time periods specified in the SEC’s rules and forms and with respect to timely communication to them and other members of management responsible for preparing periodic reports of all material information required to be disclosed in this report as it relates to Arch Capital and its consolidated subsidiaries.

We continue to enhance our operating procedures and internal controls 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.

Changes in Internal Controls Over Financial Reporting

There have been no changes in internal control over financial reporting that occurred during the quarter ended ~~September~~June 30, ~~2019~~2020 that have materially affected, or are reasonably likely to materially affect, internal control over financial reporting. We have not experienced any material impact to our internal controls over financial reporting despite the fact that most of our employees are working remotely due to the COVID-19. We are continually monitoring and assessing COVID-19 situation on our internal controls to minimize the impact on their design and operating effectiveness.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

We, in common with the insurance industry in general, are subject to litigation and arbitration in the normal course of our business. As of ~~September~~June 30, ~~2019,~~2020, we were not a party to any litigation or arbitration which is expected by management to have a material adverse effect on our results of operations and financial condition and liquidity.

ITEM 1A. RISK FACTORS

~~There were~~Our business is subject to a number of risks, including those identified in Part I—Item 1A of our 2019 Form 10-K, that could have a material adverse effect on our business, results of operations, financial condition and/or liquidity and that could cause our operating results to vary significantly from period to period. The risks described in our 2019 Form 10-K are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also could have a material adverse effect on our business, results of operations, financial condition and/or liquidity. Other than as described below, there have been no material changes ~~from~~to the risk factors ~~previously~~ disclosed in Part I—Item 1A of our ~~Annual Report~~2019 Form 10-K.

The impact of COVID-19 and related risks could materially affect our results of operations, financial position and/or liquidity.

The continuing global pandemic related to the novel coronavirus COVID-19 has impacted the global economy, financial markets and our results of operations. In addition, COVID-19 could materially disrupt the business operations of third parties with whom we interact. Because of the size and breadth of this pandemic, all of the direct and indirect consequences of COVID-19 are not yet known and may not emerge for some time.

The pandemic could have a significant effect on our Company’s business, results of operations, and current and future financial performance. We may experience higher levels of loss and claims activity in certain lines of business and our premiums written and earned could also be adversely affected by a suppression of global commercial activity that results in a reduction in insurable assets and other exposure. Conditions of the financial markets resulting from the virus may also have a negative effect on the value and quality of the assets we hold within our portfolio of invested assets, thereby adversely affecting our investment income and increasing our credit and related risk. Certain lines of our business may require additional forms of collateral in the event of a decline in the fair value of securities and benchmarks to which those repayment mechanisms are linked. The continued impacts of the pandemic to the financial markets may also adversely affect our ability to fund through public or private equity offerings, debt financings, and through other means at acceptable terms. For a further discussion, see “We could face unanticipated losses from war, terrorism, cyber-attacks, pandemics and political instability, and these or other unanticipated losses could have a material adverse effect on our financial condition and results of operations” and “Emerging claim and coverage issues may adversely affect our business” included in “Part I-Item 1A-Risk Factors” in our 2019 Form ~~10-K~~10-K.

The disruption in the financial markets related to COVID-19 has contributed to net realized losses, primarily due to the impact of changes in fair value on our equity investments and, to a lesser extent, our fixed-income investment portfolio. Our corporate fixed income portfolio may be adversely impacted by ratings downgrades, increased bankruptcies and credit spread widening in distressed industries, such as energy, gaming, lodging and leisure, autos, airlines and retail. In addition, in recent years, many state and local governments have been operating under deficits or projected deficits. These deficits may be exacerbated by the costs of responding to COVID-19 and reduced tax revenues due to adverse economic conditions. The severity and duration of these deficits could have an adverse impact on the collectability and valuation of our municipal bond portfolio. Our investment portfolio also includes residential mortgage-backed securities, commercial mortgage-backed securities and commercial mortgage loans, all of which could be adversely impacted by declines in real estate valuations and/or financial market disruption, including a heightened collection risk on the underlying mortgages and on rent receivables. Further disruptions in global financial markets due to the continuing impact of COVID-19 could result in additional net realized investment losses, including potential impairments in our fixed income portfolio. In addition, declines in fixed income yields would result in decreases in net investment income from future investment activity, including re-investments. Furthermore, issuers of the investments we hold under the equity method of accounting report their financial information to us one month to three months following

the end of the reporting period. Accordingly, the adverse impact of any disruptions in global financial markets on equity method income from these investments would likely not be reflected in our current quarter results and would instead be reported in the subsequent quarter. Further disruptions in global financial markets could adversely impact our net investment income in future periods from its non-fixed income investment portfolio. For further discussion of the risks related to our investment portfolio see “We may be adversely affected by changes in economic conditions, including interest rate changes” and “The determination of the amount of allowances and impairments taken on our investments is highly subjective and could materially impact our results of operations or financial position” included in “Part I—Item 1A—Risk Factors” in our 2019 Form 10-K.

Governmental, regulatory and rating actions in response to the COVID-19 pandemic may adversely affect our financial performance and our ability to conduct our businesses as we have in the past.

Federal, state and local government actions in the U.S. and other countries where we do business to address and mitigate the impact of COVID-19 may adversely affect us. For example, we are potentially subject to legislative and/or regulatory action that seeks to retroactively mandate coverage for losses which our insurance policies were not designed or priced to cover. Currently, in some states there is proposed legislation to require insurers to cover business interruption claims irrespective of terms, exclusions or other conditions included in the ~~year ended~~policies that would otherwise preclude coverage. In addition, a number of states have instituted, and other states are considering instituting, changes designed to effectively expand workers' compensation coverage by creating presumptions of compensability of claims for certain types of workers. Regulatory restrictions or requirements could also impact pricing, risk selection and our rights and obligations with respect to our policies and insureds, including our ability to cancel policies or our right to collect premiums. Some state regulators have issued orders to review insurers’ rates to determine whether premium refunds are required, and regulators in other states could take similar actions. Many insurers, including us, have also voluntarily provided, and may further provide, premium refunds to their customers. It is also possible that changes in economic conditions and steps taken by federal, state and local governments in response to COVID-19 could require an increase in taxes at the federal, state and local levels, which would adversely impact our results of operations.

We expect the pandemic to result in a material increase in new defaults as borrowers fail to make timely payments on their mortgages, including as a result of entering mortgage forbearance programs that allow borrowers to defer mortgage payments, which may impact our eligible insurers’ ability to remain compliant with the Private Mortgage Insurers Eligibility

Requirements (“PMIERs”) financial requirements. On March 18, 2020, the Federal Housing Finance Agency (“FHFA”) directed Fannie Mae and Freddie Mac (the “GSEs”), the primary purchasers of mortgages insured by the Company, to suspend foreclosures and evictions for at least 60 days and to provide payment forbearance to borrowers impacted by COVID-19. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act") was enacted. The CARES Act suspends foreclosures and evictions for at least 60 days from March 18, 2020, on mortgages purchased or securitized by the GSEs. In addition, the CARES Act provides for payment forbearance for up to 360 days to borrowers experiencing a hardship during the COVID-19 emergency. On June 17, 2020, FHFA directed Fannie Mae and Freddie Mac to extend the suspension of eviction and foreclosure-related activities through at least August 31, 2020.

Consistent with the CARES Act, the GSEs will provide a forbearance plan to any borrower who requests a forbearance with an attestation of the financial hardship caused by the COVID-19 emergency; and no additional documentation other than the borrower’s attestation to a financial hardship caused by the COVID-19 emergency is required. It is unclear how many borrowers will obtain forbearance plans, the length of assistance borrowers will require, and whether borrowers will be able to resume their mortgage payments thereafter. Increases in unemployment as well as borrowers entering into forbearance plans will result in higher notices of delinquency (“NODs”) which may have an adverse impact on our results or operations. In addition, as a result of COVID-19-related relief programs, the defaults related to the pandemic, if not cured, could remain in our defaulted loan inventory for a protracted period of time, potentially resulting in higher frequency (claim rate) and severity (amount of the claim) for those loans that ultimately result in a claim. Accordingly, extended or extensive forbearance programs and other changes in regulations or laws may adversely impact our mortgage insurance segment.

When a borrower obtains a forbearance plan and does not make their mortgage payment for two consecutive months, the servicer will report the NOD with a special code that indicates the loan is subject to a COVID-19 related forbearance plan. Under PMIERs, eligible insurers are required to hold additional risk-based required assets for delinquent mortgages. However, this amount is reduced for mortgages backed by a property located in a FEMA Declared Major Disaster Area that are either 1) subject to a forbearance plan executed in response to a FEMA Declared Major Disaster Area eligible for Individual Assistance, or 2) has an initial default date occurring up to either (i) 30 days prior to or (ii) 90 days following the Major Disaster event. FEMA has issued Major Disaster Area declarations in all states related to COVID-19, noting the incident date as January 20, 2020. On June 30, 2020, the GSEs published guidance clarifying the applicability of the reduced delinquent loan charges on loans with their first missed payments occurring between March 1, 2020 and December 31, ~~2018.~~2020 in response to



ARCH CAPITAL	73	2020 SECOND QUARTER FORM 10-Q

Table of Contents

a hardship related to Covid-19. Additionally, through March 31, 2021, the GSEs have temporarily required eligible insurers to obtain prior approval of dividends or entering into any new arrangements or altering any existing arrangements under tax sharing and intercompany expense-sharing agreements. The Company is reliant on the accurate reporting of servicers to correctly identify which NODs are subject to COVID-19 related forbearance plans and, the reduced delinquent loan charge. In addition, the rating agencies continually review the financial strength ratings assigned to the Company and its subsidiaries, and the ratings are subject to change. The COVID-19 pandemic and its impact on financial results and condition, could cause one or more of the rating agencies to downgrade the ratings assigned to the Company and its subsidiaries.

The disruption and other effects caused by COVID-19 could adversely impact our business operations, which could adversely affect our financial performance and results.

To protect our employees and in response to the global and regional restrictions on interpersonal contact and travel because of the COVID-19 pandemic, our work force (other than a small percentage of workers performing services which require them to visit the office) is working remotely, placing increased demands on our IT systems. Remote working arrangements may increase the risk of cyber-security attacks or data security incidents. While we have continued to conduct our business effectively, there is no assurance that our ability to continue to function in this new environment will not be adversely affected by an extended period of limited access to our physical facilities or by other developments such as an extended disruption to our systems that support our remote work capability. We depend on third-party platforms and other infrastructure to provide certain of our products and services, and such third-party infrastructures face similar risks. In addition, the continuation of the COVID-19 pandemic may continue to adversely affect our business operations, including our ability to carry on business development activities and unavailability of employees due to illness or quarantines, among others. For a further discussion, see “Our information technology systems may be unable to meet the demands of customers” and “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 and/or expose us to litigation” included in “Part I—Item 1A-Risk Factors” in our 2019 Form 10-K.

ITEM 5. OTHER INFORMATION

In accordance with Section 10a(i)(2) of the Securities Exchange Act of 1934, as amended, we are responsible for disclosing non-audit services to be provided by our independent auditor, PricewaterhouseCoopers LLP, which are approved by the Audit Committee of our board of directors. During the ~~2019 third~~2020 second quarter, the Audit Committee approved engagements of PricewaterhouseCoopers LLP for permitted non-audit services, which consisted of tax consulting services, tax compliance services and other accounting consulting services.

Disclosure of Certain Activities Under Section 13(r) of the Securities Exchange Act of 1934

Section 13(r) of the Securities Exchange Act of 1934, as amended, requires an issuer to disclose in its annual or quarterly reports whether it or an affiliate knowingly engaged in certain activities described in that section, including certain activities related to Iran during the period covered by the report.

Certain of our non-U.S. subsidiaries underwrite insurance and facultative reinsurance on a global basis to non-U.S. insureds and insurers, including for liability, marine, aviation and energy risks. Coverage provided to non-Iranian business may indirectly cover an exposure in Iran. For example, certain of our operations underwrite global marine hull and cargo policies that provide coverage for vessels navigating into and out of ports worldwide, including Iran. For the quarter ended ~~September~~June 30, ~~2019,~~2020, there has been no material amount of premium allocated or apportioned to activities relating to Iran, and we are unable to attribute gross revenues or net profits from any such policies because they insure multiple voyages and fleets containing multiple ships. Such non-U.S. subsidiaries will continue to provide such coverage only to the extent permitted by applicable law.
