NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Summary of Significant Accounting Policies

Markel Corporation is a diverse financial holding company serving a variety of niche markets. Markel Corporation's principal business markets and underwrites specialty insurance products. Through its wholly owned subsidiary, Markel Ventures, Inc. (Markel Ventures), Markel Corporation also owns interests in various businesses that operate outside of the specialty insurance marketplace. See note 2 for details regarding reportable segments.

a) Basis of Presentation. The consolidated balance sheet as of June 30, 2021 and the related consolidated statements of income (loss) and comprehensive income (loss) and changes in equity for the quarters and six months ended June 30, 2021 and 2020, and the consolidated statements of cash flows for the six months ended June 30, 2021 and 2020 are unaudited. In the opinion of management, all adjustments necessary for fair presentation of such consolidated financial statements have been included. Such adjustments consist only of normal, recurring items. Interim results are not necessarily indicative of results of operations for the entire year. The consolidated balance sheet as of December 31, 2020 was derived from Markel Corporation's audited annual consolidated financial statements.

The accompanying consolidated financial statements have been prepared in accordance with United States (U.S.) generally accepted accounting principles (GAAP) and include the accounts of Markel Corporation and its consolidated subsidiaries, as well as any variable interest entities (VIEs) that meet the requirements for consolidation (the Company). All significant intercompany balances and transactions have been eliminated in consolidation. The Company consolidates the results of its Markel Ventures subsidiaries on a one-month lag, with the exception of significant transactions or events that occur during the intervening period. Certain prior period amounts have been reclassified to conform to the current period presentation.

The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities. Actual results may differ materially from the estimates and assumptions used in preparing the consolidated financial statements.

The consolidated financial statements and notes are presented as permitted by Form 10-Q and do not contain certain information included in the Company's annual consolidated financial statements and notes. Readers are urged to review the Company's 2020 Annual Report on Form 10-K for a more complete description of the Company's business and accounting policies, as well as a description of the risks and uncertainties associated with the COVID-19 pandemic on the Company's businesses and results of operations, financial condition and cash flows, including in note 20 of the notes to consolidated financial statements included under Item 8 Financial Statements and Supplementary Data. There were no material changes in the Company's assessment of the risks and uncertainties associated with the COVID-19 pandemic during the six months ended June 30, 2021.

The Company adopted Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, effective January 1, 2021.

In August 2018, the FASB issued ASU No. 2018-12, Financial Services—Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts. The FASB subsequently issued several ASUs as amendments to ASU No. 2018-12. The standard requires insurance entities with long duration contracts to: (1) review and, if there is a change, update the assumptions used to measure expected cash flows at least annually; (2) update the discount rate assumption at each reporting date; (3) measure all market risk benefits associated with deposit (or account balance) contracts at fair value; and (4) disclose liability rollforwards and information about significant inputs, judgments, assumptions and methods used to measure the liability, including changes thereto and the effect of those changes on measurement. ASU No. 2018-12 becomes effective for the Company during the first quarter of 2023. The standard will, among other things, impact the discount rate used in estimating reserves for the Company's life and annuity reinsurance portfolio, which is in runoff. Currently, the discount rate assumption is locked-in for the life of the contracts, unless there is a loss recognition event. The Company is currently evaluating ASU No. 2018-12 to determine the impact that adopting this standard will have on its consolidated financial statements.

2. Segment Reporting Disclosures

The chief operating decision maker reviews the Company's ongoing underwriting operations on a global basis in the following two segments: Insurance and Reinsurance. In determining how to allocate resources and assess the performance of its underwriting results, management considers many factors, including the nature of the insurance product sold, the type of account written and the type of customer served. The Insurance segment includes all direct business and facultative placements written within the Company's underwriting operations. The Reinsurance segment includes all treaty reinsurance written within the Company's underwriting operations. All investing activities related to the Company's insurance operations are included in the Investing segment.

The chief operating decision maker reviews and assesses Markel Ventures' performance in the aggregate, as a single operating segment. The Markel Ventures segment primarily consists of controlling interests in a diverse portfolio of businesses that operate in various industries.

The Company's other operations primarily consist of the results of the Company's insurance-linked securities operations and program services business. Other operations also include results for lines of business discontinued prior to, or in conjunction with, acquisitions, including development on asbestos and environmental loss reserves and results attributable to the run-off of life and annuity reinsurance business, which are monitored separately from the Company's ongoing underwriting operations. For purposes of segment reporting, none of these other operations are considered to be reportable segments.

Segment profit for each of the Company's underwriting segments is measured by underwriting profit. The property and casualty insurance industry commonly defines underwriting profit as earned premiums net of losses and loss adjustment expenses and underwriting, acquisition and insurance expenses. Underwriting profit does not replace operating income or net income computed in accordance with U.S. GAAP as a measure of profitability. Underwriting profit or loss provides a basis for management to evaluate the Company's underwriting performance. Segment profit for the Company's underwriting segments may also include other revenues and expenses that are attributable to the Company's underwriting operations that are not captured in underwriting profit. Segment profit for the Investing segment is measured by net investment income and net investment gains. Segment profit for the Markel Ventures segment is measured by operating income.

For management reporting purposes, the Company allocates assets to its underwriting operations and to its Investing and Markel Ventures segments and certain of its other operations, including its insurance-linked securities and program services operations. Underwriting assets include assets attributed to the Company's Insurance and Reinsurance segments, discontinued underwriting lines of business, as well as assets that are not specifically allocated to the Company's other operations. Generally, the Company manages its underwriting assets in the aggregate and therefore does not allocate assets to individual underwriting segments.

At December 31, 2020, the Company held 36 available-for-sale securities with a total estimated fair value of $502.0 million and gross unrealized losses of $963 thousand. Of these 36 securities, six securities had been in a continuous unrealized loss position for one year or longer and had a total estimated fair value of $5.5 million and gross unrealized losses of $20 thousand.

Table of Contents

The Company completes a detailed analysis each quarter to assess whether the decline in the fair value of any investment below its cost basis is the result of a credit loss. All available-for-sale securities with unrealized losses are reviewed. The Company considers many factors in completing its quarterly review of securities with unrealized losses for credit-related impairment to determine whether a credit loss exists, including the extent to which fair value is below cost, the implied yield to maturity, rating downgrades of the security and whether or not the issuer has failed to make scheduled principal or interest payments. The Company also takes into consideration information about the financial condition of the issuer and industry factors that could negatively impact the capital markets.

If the decline in fair value of an available-for-sale security below its amortized cost is considered to be the result of a credit loss, the Company compares the estimated present value of the cash flows expected to be collected to the amortized cost of the security. The extent to which the estimated present value of the cash flows expected to be collected is less than the amortized cost of the security represents the credit loss, which is recorded as an allowance and recognized in net income. The allowance is limited to the difference between the fair value and the amortized cost of the security. Any remaining decline in fair value represents the non-credit portion of the impairment, which is recognized in other comprehensive income. The Company did not have an allowance for credit losses as of June 30, 2021 or December 31, 2020.

Quarterly, the Company also considers whether it intends to sell an available-for-sale security or if it is more likely than not that it will be required to sell the security before recovery of its amortized cost. In these instances, a decline in fair value is recognized in net income based on the fair value of the security at the time of assessment, resulting in a new cost basis for the security.

c) The amortized cost and estimated fair value of fixed maturity securities at June 30, 2021 are shown below by contractual maturity.

4. Fair Value Measurements

ASC 820, Fair Value Measurements and Disclosures, establishes a three-level hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). If the inputs used to measure the assets or liabilities fall within different levels of the hierarchy, the classification is based on the lowest level input that is significant to the fair value measurement of the asset or liability.

Classification of assets and liabilities within the hierarchy considers the markets in which the assets and liabilities are traded and the reliability and transparency of the assumptions used to determine fair value. The hierarchy requires the use of observable market data when available. The levels of the hierarchy are defined as follows:

Level 1 – Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities traded in active markets.

Level 2 – Inputs to the valuation methodology include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and market-corroborated inputs.

Level 3 – Inputs to the valuation methodology are unobservable for the asset or liability and are significant to the fair value measurement.

Table of Contents

In accordance with ASC 820, the Company determines fair value based on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In determining fair value, the Company uses various methods, including the market, income and cost approaches. The Company uses valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. The following section describes the valuation methodologies used by the Company to measure assets and liabilities at fair value, including an indication of the level within the fair value hierarchy in which each asset or liability is generally classified.

Available-for-sale investments and equity securities. Available-for-sale investments and equity securities are recorded at fair value on a recurring basis. Available-for-sale investments include fixed maturity securities and short-term investments. Short-term investments include certificates of deposit, commercial paper, discount notes and treasury bills with original maturities of one year or less. Fair value for available-for-sale investments and equity securities are determined by the Company after considering various sources of information, including information provided by a third party pricing service. The pricing service provides prices for substantially all of the Company's fixed maturity securities and equity securities. In determining fair value, the Company generally does not adjust the prices obtained from the pricing service. The Company obtains an understanding of the pricing service's valuation methodologies and related inputs, which include, but are not limited to, reported trades, benchmark yields, issuer spreads, bids, offers, duration, credit ratings, estimated cash flows and prepayment speeds. The Company validates prices provided by the pricing service by reviewing prices from other pricing sources and analyzing pricing data in certain instances.

The Company has evaluated the various types of securities in its investment portfolio to determine an appropriate fair value hierarchy level based upon trading activity and the observability of market inputs. Level 1 investments include those traded on an active exchange, such as the New York Stock Exchange. Level 2 investments include U.S. Treasury securities, U.S. government-sponsored enterprises, municipal bonds, foreign government bonds, commercial mortgage-backed securities, residential mortgage-backed securities, asset-backed securities and corporate debt securities. Level 3 investments include the Company's investments in certain insurance-linked securities funds managed by Markel CATCo Investment Management Ltd. (MCIM), a consolidated subsidiary, that are not traded on an active exchange, as further described and defined in note 10 (the Markel CATCo Funds), and are valued using unobservable inputs.

Fair value for available-for-sale investments and equity securities is measured based upon quoted prices in active markets, if available. Due to variations in trading volumes and the lack of quoted market prices, fixed maturity securities are classified as Level 2 investments. The fair value of fixed maturity securities is normally derived through recent reported trades for identical or similar securities, making adjustments through the reporting date based upon available market observable data previously described. If there are no recent reported trades, the fair value of fixed maturity securities may be derived through the use of matrix pricing or model processes, where future cash flow expectations are developed based upon collateral performance and discounted at an estimated market rate. Significant inputs used to determine the fair value of obligations of states, municipalities and political subdivisions, corporate bonds and obligations of foreign governments include reported trades, benchmark yields, issuer spreads, bids, offers, credit information and estimated cash flows. Significant inputs used to determine the fair value of commercial mortgage-backed securities, residential mortgage-backed securities and asset-backed securities include the type of underlying assets, benchmark yields, prepayment speeds, collateral information, tranche type and volatility, estimated cash flows, credit information, default rates, recovery rates, issuer spreads and the year of issue.

Due to the significance of unobservable inputs required in measuring the fair value of the Company's investments in the Markel CATCo Funds, these investments are classified as Level 3 within the fair value hierarchy. The fair value of the securities are derived using their reported net asset value (NAV) as the primary input, as well as other observable and unobservable inputs as deemed necessary by management. Management has obtained an understanding of the inputs, assumptions, process and controls used to determine NAV, which is calculated by an independent third party. Unobservable inputs to the NAV calculations include assumptions around premium earnings patterns and loss reserve estimates for the underlying securitized reinsurance contracts in which the Markel CATCo Funds invest. In July 2019, the Markel CATCo Funds were placed into run-off and capital is being returned to investors as it becomes available, the timing of which is impacted by contractual terms regarding release of collateral on the underlying securitized reinsurance contracts, as well as required regulatory approvals.

The Company's valuation policies and procedures for Level 3 investments are determined by management. Fair value measurements are analyzed quarterly to ensure the change in fair value from prior periods is reasonable relative to management's understanding of the underlying investments, recent market trends and external market data.

Table of Contents

Senior long-term debt and other debt. Senior long-term debt and other debt is carried at amortized cost with the estimated fair value disclosed on the consolidated balance sheets. Senior long-term debt and other debt is classified as Level 2 within the fair value hierarchy due to variations in trading volumes and the lack of quoted market prices. Fair value for senior long-term debt and other debt is generally derived through recent reported trades for identical securities, making adjustments through the reporting date, if necessary, based upon available market observable data including U.S. Treasury securities and implied credit spreads. Significant inputs used to determine the fair value of senior long-term debt and other debt include reported trades, benchmark yields, issuer spreads, bids and offers.

The following tables present the balances of assets measured at fair value on a recurring basis by level within the fair value hierarchy.

In connection with the run-off of one of the Markel CATCo Funds and to facilitate the return of capital to third party investors, the Company invested $90.0 million in that fund effective January 1, 2020. This investment replaced collateral previously provided by other investors for risk exposures within the underlying reinsurance contracts in which the fund is invested related to loss events that occur after December 31, 2019 and through the expiration of the reinsurance contracts. All of these reinsurance contracts expired or were commuted in 2020, however, the Company continues to have exposure to adverse loss development on 2020 exposures under these contracts through its investment in the fund.

The Company did not have any assets or liabilities measured at fair value on a non-recurring basis during the six months ended June 30, 2021 and 2020.

For the six months ended June 30, 2021, current accident year losses and loss adjustment expenses included $67.9 million of net losses and loss adjustment expenses from Winter Storm Uri. The net losses and loss adjustment expenses from Winter Storm Uri as of June 30, 2021 represent the Company's best estimates based upon information currently available. The estimates for these losses are based on claims received to date, detailed policy and reinsurance contract level reviews, industry loss estimates and output from both industry and proprietary models, as well as analysis of the Company's ceded reinsurance contracts. These estimates are based on various assumptions about coverage, liability and reinsurance and are therefore subject to change. While the Company believes its reserves for Winter Storm Uri as of June 30, 2021 are adequate, it continues to closely monitor reported claims and will adjust estimates of gross and net losses as new information becomes available.

For the six months ended June 30, 2020, current accident year losses and loss adjustment expenses included $325.0 million of net losses and loss adjustment expenses attributed to the COVID-19 pandemic.

For the six months ended June 30, 2021, prior accident years losses and loss adjustment expenses included $226.1 million of favorable development on prior years loss reserves, which included $213.3 million of favorable development on the Company's general liability, workers' compensation, marine and energy, property and professional liability product lines within the Insurance segment. Favorable development on prior years loss reserves for the six months ended June 30, 2021 was partially offset by $32.8 million of adverse development on the Company's property product lines within the Reinsurance segment, due in part to an increase in our estimate of ultimate losses and loss adjustment expenses directly attributed to COVID-19 in the first quarter of 2021. The Company's estimate of ultimate losses directly attributed to COVID-19 is based on assumptions about coverage, liability and reinsurance, for which significant uncertainty still exists, and represents the Company's best estimate as of June 30, 2021 based upon information currently available. While the Company believes the net reserves for losses and loss adjustment expenses for COVID-19 as of June 30, 2021 are adequate based on information available at this time, the Company continues to closely monitor reported claims, government actions, judicial decisions and changes in the levels of worldwide social disruption and economic activity arising from the pandemic and will adjust the estimates of gross and net losses as new information becomes available. Such adjustments to the Company's reserves for COVID-19 losses and loss adjustment expenses may be material to the Company's results of operations, financial condition and cash flows.

Table of Contents

For the six months ended June 30, 2020, prior accident years losses and loss adjustment expenses included $268.2 million of favorable development on prior years loss reserves, which included $206.6 million of favorable development on the Company's professional liability, general liability and workers' compensation product lines within the Insurance segment and property and general liability product lines within the Reinsurance segment.

The percentage of consolidated assumed earned premiums to net earned premiums was 24% and 25% and for the quarter and six months ended June 30, 2021, respectively, and 27% for both the quarter and six months June 30, 2020.

Substantially all of the incurred losses and loss adjustment expenses in the Company's program services and other fronting operations, which totaled $636.8 million and $1.1 billion for the quarter and six months ended June 30, 2021, respectively, and $394.5 million and $702.5 million for the quarter and six months ended June 30, 2020, respectively, were ceded.

8. Life and Annuity Benefits

Life and annuity benefits are compiled on a reinsurance contract-by-contract basis and are discounted using standard actuarial techniques and cash flow models. Since the development of the life and annuity reinsurance reserves is based upon cash flow projection models, the Company must make estimates and assumptions based on cedent experience, industry mortality tables, and expense and investment experience, including a provision for adverse deviation. The assumptions used to determine policy benefit reserves are generally locked-in for the life of the contract unless an unlocking event occurs. Loss recognition testing is performed to determine if existing policy benefit reserves, together with the present value of future gross premiums and expected investment income earned thereon, are adequate to cover the present value of future benefits, settlement and maintenance costs. If the existing policy benefit reserves are not sufficient, the locked-in assumptions are revised to current best estimate assumptions and a charge to earnings for life and annuity benefits is recognized at that time.

Life and annuity benefits are also adjusted to the extent unrealized gains on the investments supporting the policy benefit reserves would result in a reserve deficiency if those gains were realized. As of June 30, 2021 and December 31, 2020, the cumulative adjustment to life and annuity benefits attributable to unrealized gains on the underlying investment portfolio totaled $69.3 million and $119.6 million, respectively. During the quarter and six months ended June 30, 2021, the Company decreased life and annuity benefits by $0.9 million and $50.3 million, respectively, reflecting an increase in the market yield on the investment portfolio supporting the policy benefit reserves, and increased the change in net unrealized holding gains included in other comprehensive income by a corresponding amount. During the quarter and six months ended June 30, 2020, the Company increased life and annuity benefits by $22.7 million and $35.6 million, respectively, as a result of decreases in the market yield on the investment portfolio supporting the policy benefit reserves, and decreased the change in net unrealized holding gains included in other comprehensive income (loss) by a corresponding amount.

9. Senior Long-Term Debt and Other Debt

In May 2021, the Company issued $600 million of 3.45% unsecured senior notes due May 2052. Net proceeds to the Company were $591.4 million, before expenses. The Company expects to use a portion of these proceeds to retire its 4.9% unsecured senior notes due July 1, 2022 ($350.0 million aggregate principal outstanding at June 30, 2021) and the remainder for general corporate purposes.

10. Variable Interest Entities

MCIM, a wholly-owned consolidated subsidiary of the Company, is an insurance-linked securities investment fund manager and reinsurance manager headquartered in Bermuda. Results attributable to MCIM are not included in a reportable segment.

MCIM serves as the insurance manager for Markel CATCo Re Ltd. (Markel CATCo Re), a Bermuda Class 3 reinsurance company, and as the investment manager for Markel CATCo Reinsurance Fund Ltd., a Bermuda exempted mutual fund company comprised of multiple segregated accounts (Markel CATCo Funds). The Markel CATCo Funds issue multiple classes of nonvoting, redeemable preference shares to investors and the Markel CATCo Funds are primarily invested in nonvoting preference shares of Markel CATCo Re. The underwriting results of Markel CATCo Re are attributed to the Markel CATCo Funds through those nonvoting preference shares. Voting shares in Markel CATCo Reinsurance Fund Ltd. and Markel CATCo Re are held by MCIM.

Table of Contents

The Markel CATCo Funds and Markel CATCo Re are considered VIEs, as their preference shareholders have no voting rights. MCIM has the power to direct the activities that most significantly impact the economic performance of these entities, but does not have a variable interest in any of the entities. With the exception of an investment in one of the Markel CATCo Funds ($41.1 million and $58.5 million as of June 30, 2021 and December 31, 2020, respectively), the Company's involvement is generally limited to that of an investment or insurance manager, receiving fees that are at market and commensurate with the level of effort required. The Company is not the primary beneficiary of the Markel CATCo Funds or Markel CATCo Re and therefore does not consolidate these entities.

The Company's exposure to risk from unconsolidated Markel CATCo Funds and Markel CATCo Re is generally limited to its investment and any earned but uncollected fees. The Company has not issued any investment performance guarantees to these VIEs or their investors. As of June 30, 2021 and December 31, 2020, net assets under management of MCIM for unconsolidated VIEs were $726.6 million and $929.2 million, respectively.

In July 2019, both the Markel CATCo Funds and Markel CATCo Re were placed into run-off, and MCIM is returning capital to investors as it becomes available. See note 13 for further details regarding developments in the Company's Markel CATCo operations.

11. Related Party Transactions

The Company engages in certain related party transactions in the normal course of business at arm's length.

Insurance-Linked Securities

Within the Company's insurance-linked securities operations, the Company provides investment and insurance management services through Nephila Holdings Ltd. (together with its consolidated subsidiaries, Nephila). Nephila serves as the investment manager to several Bermuda, Ireland and U.S. based private funds (the Nephila Funds). To provide access for the Nephila Funds to the insurance, reinsurance and weather markets, Nephila also provides managing general agent services and acts as an insurance manager to certain Bermuda Class 3 and 3A reinsurance companies and Lloyd's Syndicate 2357 (Syndicate 2357) (collectively, the Nephila Reinsurers), as well as other unaffiliated insurance entities. Nephila receives management fees for investment and insurance management services provided through its insurance-linked securities operations based on the net asset value of the accounts managed, and, for certain funds, incentive fees based on the annual performance of the funds managed. Nephila also receives commissions from the Nephila Reinsurers, which are based on the direct written premiums of the insurance contracts placed. For the quarter and six months ended June 30, 2021, total revenues attributed to unconsolidated entities managed by Nephila were $42.0 million and $70.7 million, respectively. For the quarter and six months ended June 30, 2020, total revenues attributed to unconsolidated entities managed by Nephila were $42.2 million and $83.7 million, respectively.

Through the Company's program services operations and other fronting arrangements, the Company has programs with Nephila through which the Company writes insurance policies that are ceded to Syndicate 2357 and certain other Nephila Reinsurers. Through these programs, Nephila utilizes certain of the Company's licensed insurance companies to write U.S. catastrophe-exposed property risk that is then ceded to Nephila Reinsurers. Gross premiums written through these programs with Nephila were $186.7 million and $304.0 million for the quarter and six months ended June 30, 2021, respectively, and $122.9 million and $213.4 million for the quarter and six months ended June 30, 2020, respectively, all of which were ceded to Nephila Reinsurers. As of June 30, 2021 and December 31, 2020, reinsurance recoverables on the consolidated balance sheets included $466.7 million and $353.8 million, respectively, due from Nephila Reinsurers. Under these programs, the Company bears underwriting risk for annual aggregate agreement year losses in excess of a limit the Company believes is unlikely to be exceeded. To the extent losses under these programs exceed the prescribed limits, the Company is obligated to pay such losses to the cedents without recourse to the Nephila Reinsurers. While the Company believes losses under these programs are unlikely, those losses, if incurred, could be material to the Company's consolidated results of operations and financial condition.

The Company has also entered into other assumed and ceded reinsurance transactions with the Nephila Reinsurers in the normal course of business, which are not material to the Company's consolidated financial statements.

The Hagerty Group, LLC

The Company holds a minority ownership interest in The Hagerty Group, LLC, which is accounted for under the equity method. Hagerty Group primarily operates as a managing general agent under the names Hagerty Insurance Agency and Hagerty Classic Marine Insurance Agency (collectively, Hagerty). Hagerty Group also includes Hagerty Re, a Bermuda Class 3 reinsurance company. Essentia Insurance Company (Essentia), one of the Company's insurance subsidiaries, is the exclusive insurance underwriter for Hagerty in the U.S., and a portion of this insurance is ceded to Hagerty Re. For the quarter and six months ended June 30, 2021, gross written premiums attributable to Hagerty written on Essentia were $176.8 million and $296.7 million, respectively, of which $100.5 million and $168.4 million, respectively, were ceded to Hagerty Re. For the quarter and six months ended June 30, 2020 gross written premiums attributable to Hagerty written on Essentia were $154.0 million and $254.9 million, respectively, of which $72.8 million and $120.6 million, respectively, were ceded to Hagerty Re.

12. Shareholders' Equity

a) The Company has 50,000,000 shares of no par value common stock authorized. The following table presents a rollforward of changes in common shares issued and outstanding.


	Quarter Ended June 30,		Six Months Ended June 30,
(in thousands)	2021	2020	2021	2020
Issued and outstanding common shares, beginning of period	13,765	13,775	13,783	13,794
Issuance of common shares	2	1	3	3
Repurchase of common shares	(33)	—	(52)	(21)
Issued and outstanding common shares, end of period	13,734	13,776	13,734	13,776

b) The Company has 10,000,000 shares of no par value preferred stock authorized, of which 600,000 shares were issued and outstanding at June 30, 2021 and December 31, 2020. The outstanding preferred shares were issued in May 2020 for an aggregate initial purchase price of $600 million and net proceeds of $591.9 million. For the quarter and six months ended June 30, 2021, total dividends declared and paid on preferred shares were $18.0 million, or $30 per share.

c) Net income (loss) per common share was determined by dividing adjusted net income (loss) to common shareholders by the applicable weighted average common shares outstanding. Basic common shares outstanding include restricted stock units that are no longer subject to any contingencies for issuance, but for which corresponding shares have not been issued. Diluted net income (loss) per common share is computed by dividing adjusted net income (loss) to common shareholders by the weighted average number of common shares and dilutive potential common shares outstanding during the period.


	Quarter Ended June 30,				Six Months Ended June 30,
(in thousands, except per share amounts)	2021		2020		2021		2020
Net income (loss) to common shareholders	$	774,110	$	921,768	$	1,347,804	$	(483,995)
Adjustment of redeemable noncontrolling interests	13,717		(13,073)		21,623		2,940
Adjusted net income (loss) to common shareholders	$	787,827	$	908,695	$	1,369,427	$	(481,055)

Basic common shares outstanding	13,793		13,808		13,806		13,812

Dilutive potential common shares from restricted stock units and restricted stock (1)	24		13		22		—
Diluted common shares outstanding	13,817		13,821		13,828		13,812
Basic net income (loss) per common share	$	57.12	$	65.81	$	99.19	$	(34.83)
Diluted net income (loss) per common share (1)	$	57.02	$	65.75	$	99.03	$	(34.83)

(1) The impact of restricted stock units and restricted stock of 11 thousand shares was excluded from the computation of diluted earnings per common share for the six months ended June 30, 2020 because the effect would have been anti-dilutive.

13. Commitments and Contingencies

a) Late in the fourth quarter of 2018, the Company was contacted by and received inquiries from the U.S. Department of Justice, U.S. Securities and Exchange Commission and Bermuda Monetary Authority (collectively, Governmental Authorities) into loss reserves recorded in late 2017 and early 2018 at Markel CATCo Re (the Markel CATCo Inquiries), an unconsolidated subsidiary managed by MCIM. As a result, the Company engaged outside counsel to conduct an internal review.

The internal review was completed in April 2019 and found no evidence that MCIM personnel acted in bad faith in exercising business judgment in the setting of reserves and making related disclosures during late 2017 and early 2018. The Company's outside counsel has met with the Governmental Authorities and reported the findings from the internal review. The Company cannot currently predict the duration, scope or result of the Markel CATCo Inquiries.

The Markel CATCo Inquiries, as well as other matters related to or arising from the Markel CATCo Inquiries, including matters of which the Company is currently unaware, could result in additional claims, litigation, investigations, enforcement actions or proceedings. For example, additional litigation may be filed by investors in the Markel CATCo Funds. The Company also could become subject to increased regulatory scrutiny, investigations or proceedings in any of the jurisdictions where it operates. If any regulatory authority takes action against the Company or the Company enters into an agreement to settle a matter, the Company may incur sanctions or be required to pay substantial fines or implement remedial measures that could prove costly or disruptive to its businesses and operations. Costs associated with the Markel CATCo Inquiries, as well as legal costs incurred in connection with any existing or future litigation or disputes, are being expensed as incurred.

An unfavorable outcome in one or more of these matters, and others the Company cannot anticipate, could have a material adverse effect on the Company's results of operations and financial condition. In addition, the Company may take further steps to mitigate potential risks or liabilities that may arise from the Markel CATCo Inquiries and related developments and some of those steps may have a material impact on the Company's results of operations or financial condition. Even if an unfavorable outcome does not materialize, these matters, and actions the Company may take in response, could have an adverse impact on the Company's reputation and result in substantial expense and disruption.

b) In 2019, the Company established Lodgepine Capital Management Limited (Lodgepine), a new retrocessional insurance-linked securities fund manager in Bermuda. Lodgepine's initial product offering is Lodgepine Fund Limited (Lodgepine Fund), a property catastrophe retrocessional investment fund, and subject to certain conditions, the Company has committed to invest up to $100 million in Lodgepine Fund. Lodgepine Fund launched July 1, 2021 with initial investor capital of $98.9 million, which includes an initial investment by the Company of $18.9 million.

c) Contingencies arise in the normal course of the Company's operations and are not expected to have a material impact on the Company's financial condition or results of operations.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

The accompanying consolidated financial statements and related notes have been prepared in accordance with United States (U.S.) generally accepted accounting principles (GAAP) and include the accounts of Markel Corporation and its consolidated subsidiaries, as well as any variable interest entities that meet the requirements for consolidation (the Company). See note 1(b) of the notes to consolidated financial statements for details of recently issued accounting pronouncements that we have not yet adopted and the expected effects on our consolidated financial position, results of operations and cash flows.

On March 11, 2020, COVID-19, a novel coronavirus outbreak, was declared a pandemic by the World Health Organization. This pandemic has caused unprecedented social and economic disruption, increased volatility of capital markets and intervention by various governments and central banks around the world. Readers are urged to review our 2020 Annual Report on Form 10-K for a comprehensive description of the impacts of the COVID-19 pandemic on our businesses and results of operations, financial condition and cash flows in 2020, as well as a description of potential future impacts to our businesses and results of operations, financial condition and cash flows, including in "Developments Related to COVID-19" under Item 7 Management's Discussion and Analysis of Financial Condition and Results of Operations. There were no material changes in our assessment of the risks and uncertainties associated with the COVID-19 pandemic during the six months ended June 30, 2021.

Our Business

We are a diverse financial holding company serving a variety of niche markets. We aspire to build one of the world's great companies and deploy three financial engines in pursuit of this goal.

Insurance - Our principal business markets and underwrites specialty insurance products using multiple platforms that enable us to best match risk and capital.

Investing - Our investing activities are primarily related to our underwriting operations. The majority of our investable assets come from premiums paid by policyholders and the remainder is comprised of shareholder funds.

Markel Ventures - Through our Markel Ventures operations, we own controlling interests in a diverse portfolio of businesses that operate outside of the specialty insurance marketplace.

Our financial goals are to earn consistent underwriting and operating profits and superior investment returns to build shareholder value. We measure financial success by our ability to grow book value per common share and the market price per common share of our stock, or total shareholder return, at high rates of return over a long period of time. To mitigate effects of short-term volatility and align with the longer-term perspective we apply to operating our businesses, we generally use five-year time periods to measure our performance. Growth in book value per common share is an important measure of our success because it includes all underwriting, operating and investing results. Over the five-year period ended June 30, 2021, the compound annual growth in book value per common share outstanding was 10%. Growth in total shareholder value is also an important measure of our success, as a significant portion of our operations are not recorded at fair value or otherwise captured in book value. Over the five-year period ended June 30, 2021, our common share price increased at a compound annual rate of 4%.

Insurance

Our insurance engine is comprised of the following types of operations:

•Underwriting - Our underwriting operations are comprised of our risk-bearing insurance and reinsurance operations.

•Insurance-linked securities - Our insurance-linked securities (ILS) operations include investment fund managers that offer a variety of investment products, including insurance-linked securities, catastrophe bonds, insurance swaps and weather derivatives, as well as managing general agents that place risks with the funds managed or with third parties.

•Program services - Our program services business serves as a fronting platform that provides other insurance entities access to the U.S. property and casualty insurance market.

Table of Contents

Through our underwriting, ILS and program services operations, we have a suite of capabilities through which we can access capital to support our customers' risks, which includes our own capital through our underwriting operations, as well as third party capital through our ILS and program services operations. Within each of these platforms, we believe that our specialty product focus and niche market strategy enable us to develop expertise and specialized market knowledge. We seek to differentiate ourselves from competitors by our expertise, service, continuity and other value-based considerations, including the multiple platforms through which we can manage risk and deploy capital. Our ability to access multiple insurance platforms allows us to achieve income streams from our insurance operations beyond the traditional underwriting model.

Underwriting

Our chief operating decision maker allocates resources to and assesses the performance of our ongoing underwriting operations on a global basis in the following two segments: Insurance and Reinsurance. In determining how to monitor our underwriting results, we consider many factors, including the nature of the insurance product sold, the type of account written and the type of customer served. The Insurance segment includes all direct business and facultative placements written across the Company. The Reinsurance segment includes all treaty reinsurance written across the Company.

Our Insurance segment includes both hard-to-place risks written outside of the standard market on an excess and surplus lines basis and unique and hard-to-place risks that must be written on an admitted basis due to marketing and regulatory reasons. Risks written in our Insurance segment are written on either a direct basis or a subscription basis, the latter of which means that the loss exposures brought into the market are typically insured by more than one insurance company or Lloyd's of London (Lloyd's) syndicate. When we write business in the subscription market, we prefer to participate as lead underwriter in order to control underwriting terms, policy conditions and claims handling. The following products are included in this segment: general liability, professional liability, primary and excess of loss property, personal property, workers' compensation, marine and energy and credit and surety coverages, specialty program insurance for well-defined niche markets and liability and other coverages tailored for unique exposures. Business in this segment is primarily written through our Markel Specialty and Markel International divisions. The Markel Specialty division writes business on both an excess and surplus lines and admitted basis, primarily based in the United States, as well as Bermuda, London, and Europe. The Markel International division writes business worldwide from our London and Munich-based platforms, which include branch offices around the world. The Insurance segment also includes collateral protection insurance written on an admitted basis through our State National division.

Our Reinsurance segment includes casualty, specialty and property treaty reinsurance products offered to other insurance and reinsurance companies globally through the broker market. Our treaty reinsurance offerings include both quota share and excess of loss reinsurance and are typically written on a participation basis, which means each reinsurer shares proportionally in the business ceded under the reinsurance treaty written. Principal lines of business include: professional liability, general liability, workers' compensation, credit and surety and property. Business in this segment is written primarily by our Global Reinsurance division. Effective January 2021, we discontinued writing property reinsurance business, including catastrophe-exposed property business, on a risk-bearing basis within our Global Reinsurance division. Instead, any such business written is now ceded to our Nephila ILS operations to be placed with third party capital to the extent it fits the ILS investors' risk profile and will be included with our other fronting operations, which are not included in a reportable segment. However, as some of our reinsurance contracts were written with multi-year terms, we will continue to have property loss exposure, including catastrophe exposure, through the expiration of those contracts, some of which extend into 2023. We also continue to have property loss exposure on our retrocessional reinsurance property business, a portion of which was ceded to Lodgepine Reinsurance Limited (Lodgepine Re) effective July 1, 2021.

Insurance-Linked Securities

Our insurance-linked securities operations are primarily comprised of our Nephila operations and are not included in a reportable segment. Nephila Holdings Ltd. (together with its subsidiaries, Nephila) serves as an insurance and investment fund manager and managing general agent that offers a broad range of investment products, including insurance-linked securities, catastrophe bonds, insurance swaps and weather derivatives. Nephila serves as the investment manager to several Bermuda, Ireland and U.S. based private funds (the Nephila Funds). To provide access for the Nephila Funds to the insurance, reinsurance and weather markets, Nephila acts as an insurance manager to certain Bermuda Class 3 and 3A reinsurance companies and Lloyd's Syndicate 2357 (Syndicate 2357) (collectively, the Nephila Reinsurers). Nephila also serves as a managing general agent that underwrites and administers property insurance policies and provides delegated underwriting services to providers of insurance capital, including Nephila Reinsurers. The results of the Nephila Reinsurers are attributed to the Nephila Funds primarily through derivative transactions between these entities. Neither the Nephila Funds nor the Nephila Reinsurers are subsidiaries of Markel Corporation, and as such, these entities are not included in our consolidated financial statements. See note 11 of the notes to consolidated financial statements for further details regarding our Nephila operations.

Table of Contents

In 2019, we established Lodgepine Capital Management Limited (Lodgepine), our new retrocessional insurance-linked securities fund manager in Bermuda. Lodgepine's initial product offering is Lodgepine Fund Limited (Lodgepine Fund), a property catastrophe retrocessional investment fund, and subject to certain conditions, we have committed to invest up to $100 million in Lodgepine Fund. Lodgepine Fund launched July 1, 2021 with initial investor capital of $98.9 million, which includes our initial investment of $18.9 million. Effective July 1, 2021, we also ceded a portion of the retrocessional reinsurance property business written in our Reinsurance segment to Lodgepine Re, which underwrites the portfolio of risks to which Lodgepine Fund subscribes.

Our insurance-linked securities operations also include our run-off Markel CATCo operations, the results of which are reported separately from our ongoing insurance-linked securities operations. Our Markel CATCo operations are conducted through Markel CATCo Investment Management Ltd. (MCIM), an ILS investment fund manager headquartered in Bermuda. In July 2019, these operations were placed into run-off, and MCIM is returning capital to investors as it becomes available. See note 10 of the notes to consolidated financial statements for further details regarding our Markel CATCo operations.

Program Services

Our program services business generates fee income in the form of ceding fees in exchange for fronting insurance business to other insurance carriers (capacity providers). In general, fronting refers to business in which we write insurance on behalf of a general agent or capacity provider and then cede all, or substantially all, of the risk under these policies to the capacity provider in exchange for ceding fees.

Our program services business, which is provided through our State National division and is separately managed from our underwriting operations, offers issuing carrier capacity to both specialty managing general agents and other producers who sell, control, and administer books of insurance business that are supported by third parties that assume reinsurance risk, including Syndicate 2357 and other Nephila Reinsurers. Through our program services business, we write a wide variety of insurance products, principally including general liability insurance, commercial liability insurance, commercial multi-peril insurance, property insurance and workers' compensation insurance. The results of our program services operations are not included in a reportable segment.

In certain instances, we may also leverage the strength of our underwriting platform to front business to our ILS operations to support their business plans and assist in meeting their desired return objectives. This business is conducted separately from our program services business and primarily consists of the catastrophe-exposed property reinsurance business previously written through our Reinsurance segment. Effective January 1, 2021, any such business written is ceded to our Nephila ILS operations to be placed with third party capital in exchange for ceding fees. Gross and ceded written premiums for this business in the first half of 2021 were not significant.

Although we reinsure substantially all of the risks inherent in our program services business and other fronting arrangements, we have certain programs that contain limits on our reinsurers' obligations to us that expose us to underwriting risk, including loss ratio caps, aggregate reinsurance limits or exclusion of the credit risk of producers. Under certain programs with Nephila Reinsurers, we also bear underwriting risk for annual aggregate agreement year losses in excess of a limit that we believe is unlikely to be exceeded. See note 11 of the notes to consolidated financial statements for further details regarding our programs with Nephila Reinsurers.

Investments

Our business strategy recognizes the importance of both consistent underwriting and operating profits and superior investment returns to build shareholder value. We rely on sound underwriting practices to produce investable funds. The majority of our investable assets come from premiums paid by policyholders. Policyholder funds are invested predominantly in high-quality government, municipal and corporate bonds that generally match the duration and currency of our loss reserves. The balance, comprised of shareholder funds, is available to be invested in equity securities, which over the long run, have produced higher returns relative to fixed maturity investments. When purchasing equity securities, we seek to invest in profitable companies, with honest and talented management, that exhibit reinvestment opportunities and capital discipline, at reasonable prices. We intend to hold these investments over the long-term. Substantially all of our investment portfolio is managed by company employees.

Table of Contents

Markel Ventures

Through our wholly-owned subsidiary Markel Ventures, Inc. (Markel Ventures), we own interests in various businesses that operate outside of the specialty insurance marketplace. These businesses are viewed by management as separate and distinct from our insurance operations. Local management teams oversee the day-to-day operations of these companies, including investment and capital allocation decisions for their respective companies. Our senior management team is responsible for decisions regarding allocation of capital for acquisitions and new investments. Our strategy in making these investments is similar to our strategy for purchasing equity securities. We seek to invest in profitable companies, with honest and talented management, that exhibit reinvestment opportunities and capital discipline, at reasonable prices. We intend to own the businesses acquired for a long period of time.

Our chief operating decision maker allocates resources to and assesses the performance of these various businesses in the aggregate as the Markel Ventures segment. This segment includes a diverse portfolio of businesses from different industries that offer various types of products and services to businesses and consumers. Our Markel Ventures products group is comprised of businesses that manufacture or produce equipment, transportation-related products and consumer and building products. Our Markel Ventures services group is comprised of businesses that provide product distribution, consulting and other types of services to businesses and consumers.

In April 2020, we acquired a controlling interest in Lansing Building Products, LLC, a supplier of exterior building products and materials to professional contractors throughout the U.S., which simultaneously acquired the distribution business of Harvey Building Products to enhance its geographic reach and scale (together, Lansing), bringing our ownership in Lansing to 91%. Results attributable to Lansing are included in our Markel Ventures segment.

(1) Net investment income and net investment gains (losses), if any, attributable to Markel Ventures are included in segment profit for Markel Ventures. All other net investment income and net investment gains (losses) are included in Investing segment profit (loss).

(2) Segment profit for the Markel Ventures segment includes amortization of intangible assets attributable to Markel Ventures.

(3) Other operations include the results attributable to our operations that are not included in a reportable segment, as well as any amortization of intangible assets that is not allocated to a reportable segment. Amortization of intangible assets attributable to our underwriting segments was $10.4 million and $20.8 million for the quarter and six months ended June 30, 2021, respectively, and $10.7 million and $21.1 million for the quarter and six months ended June 30, 2020, respectively; however, we do not allocate amortization of intangible assets between the Insurance and Reinsurance segments.

The decrease in comprehensive income to shareholders from the second quarter of 2020 to the second quarter of 2021 was primarily due to a decrease in pre-tax net investment gains from $911.2 million in 2020 to $674.8 million in 2021.

The change in comprehensive income (loss) to shareholders from the first half of 2020 to the first half of 2021 was primarily due to pre-tax net investment gains of $1.2 billion in 2021 compared to pre-tax net investment losses of $770.2 million in 2020. We also recognized meaningful underwriting profits in 2021 compared to underwriting losses in 2020, which included $325.0 million of pre-tax net losses and loss adjustment expenses attributed to COVID-19.

The components of net income (loss) to shareholders and comprehensive income (loss) to shareholders are discussed in further detail under "Underwriting Results," "Investing Results," "Markel Ventures," "Other Operations," "Interest Expense and Income Taxes" and "Comprehensive Income (Loss) to Shareholders and Book Value per Common Share."

Underwriting Results

Underwriting profits are a key component of our strategy to build shareholder value. We believe that the ability to achieve consistent underwriting profits demonstrates knowledge and expertise, commitment to superior customer service and the ability to manage insurance risk. The property and casualty insurance industry commonly defines underwriting profit or loss as earned premiums net of losses and loss adjustment expenses and underwriting, acquisition and insurance expenses. We use underwriting profit or loss and the combined ratio as a basis for evaluating our underwriting performance. The U.S. GAAP combined ratio is a measure of underwriting performance and represents the relationship of incurred losses, loss adjustment expenses and underwriting, acquisition and insurance expenses to earned premiums. The combined ratio is the sum of the loss ratio and the expense ratio. The loss ratio represents the relationship of incurred losses and loss adjustment expenses to earned premiums. The expense ratio represents the relationship of underwriting, acquisition and insurance expenses to earned premiums. A combined ratio less than 100% indicates an underwriting profit, while a combined ratio greater than 100% reflects an underwriting loss.

Table of Contents

In addition to the U.S. GAAP combined ratio, loss ratio and expense ratio, we also evaluate our underwriting performance using measures that exclude the impacts of certain items on these ratios. We believe these adjusted measures, which are non-GAAP measures, provide financial statement users with a better understanding of the significant factors that comprise our underwriting results and how management evaluates underwriting performance.

When analyzing our combined ratio, we exclude current accident year losses and loss adjustment expenses attributed to natural catastrophes. We also exclude losses and loss adjustment expenses attributed to certain significant, infrequent loss events, for example, the COVID-19 pandemic. Due to the unique characteristics of a catastrophe loss, there is inherent variability as to the timing or loss amount, which cannot be predicted in advance. The same is true for the COVID-19 pandemic, as there are no events in recent history with characteristics similar to COVID-19. We believe measures that exclude the effects of catastrophe events, and COVID-19, are meaningful to understand the underlying trends and variability in our underwriting results that may be obscured by these items.

When analyzing our loss ratio, we evaluate losses and loss adjustment expenses attributable to the current accident year separate from losses and loss adjustment expenses attributable to prior accident years. Prior accident year reserve development, which can either be favorable or unfavorable, represents changes in our estimates of losses and loss adjustment expenses related to loss events that occurred in prior years. We believe a discussion of current accident year loss ratios, which exclude prior accident year reserve development, is helpful since it provides more insight into estimates of current underwriting performance and excludes changes in estimates related to prior year loss reserves. We also analyze our current accident year loss ratio excluding losses and loss adjustment expenses attributable to catastrophes, and in 2020, the COVID-19 pandemic, for the reasons previously discussed. The current accident year loss ratio excluding the impact of catastrophes and significant, infrequent loss events is also commonly referred to as an attritional loss ratio within the property and casualty insurance industry.

Premiums

The increase in gross premium volume in our underwriting operations for both the quarter and six months ended June 30, 2021 reflected significant growth, most notably within our professional liability and general liability product lines, across both of our underwriting segments.

We continue to see more favorable rates across most of our product lines, particularly within our general liability and professional liability product lines, based on general market conditions. Additionally, following the high level of catastrophes that have occurred in recent years, we are also seeing more favorable rates on catastrophe-exposed lines of business. The primary exception to the favorable rate environment is workers' compensation, where we continue to see low single digit rate decreases given generally favorable loss experience in recent years. When we believe the prevailing market price will not support our underwriting profit targets, the business is not written. As a result of our underwriting discipline, gross premium volume may vary when we alter our product offerings to maintain or improve underwriting profitability.

Net retention of gross premium volume in our underwriting operations for the quarter ended June 30, 2021 was 83% compared to 82% for the same period of 2020. Net retention of gross premium volume in our underwriting operations for the six months ended June 30, 2021 was 85% compared to 84% for the same period of 2020. The increase in net retention for both periods was driven by changes in mix of business within our Reinsurance segment. Within our underwriting operations, we purchase reinsurance and retrocessional reinsurance to manage our net retention on individual risks and overall exposure to losses and to enable us to write policies with sufficient limits to meet policyholder needs.

The increase in earned premiums in our underwriting operations for both the quarter and six months ended June 30, 2021 was primarily attributable to the higher gross premium volume within our professional liability and general liability product lines.

Combined Ratio

The decrease in our consolidated combined ratio for the quarter ended June 30, 2021 compared to the same period of 2020 was driven by a lower current accident year loss ratio in our Insurance segment and lower expense ratio across both of our underwriting segments, partially offset by the impact of less favorable development on prior accident years loss reserves in 2021 compared to 2020. Higher earned premiums in 2021 compared to 2020 had a favorable impact on our expense ratio and an unfavorable impact on the prior accident years loss ratio.

Underwriting results for the six months ended June 30, 2021 included $67.9 million of net losses and loss adjustment expenses from Winter Storm Uri as well as $18.5 million of net losses and loss adjustment expenses resulting from an increase in our estimate of ultimate losses and loss adjustment expenses directly attributed to COVID-19. Underwriting results for the six months ended June 30, 2020 included $325.0 million of net losses and loss adjustment expenses attributed to COVID-19. Excluding these losses attributed to Winter Storm Uri and COVID-19, the decrease in our consolidated combined ratio for the six months ended June 30, 2021 compared to the same period of 2020 was driven by a lower current accident year loss ratio and lower expense ratio across both of our underwriting segments, partially offset by the impact of less favorable development on prior accident years loss reserves in 2021 compared to 2020. Higher earned premiums in 2021 compared to 2020 had a favorable impact on our expense ratio and an unfavorable impact on the prior accident years loss ratio.

The net losses and loss adjustment expenses from Winter Storm Uri as of June 30, 2021 represent our best estimates based upon information currently available. Our estimates for these losses are based on claims received to date, detailed policy and reinsurance contract level reviews, industry loss estimates and output from both industry and proprietary models, as well as analysis of our ceded reinsurance contracts. These estimates are based on various assumptions about coverage, liability and reinsurance and are therefore subject to change. While we believe our reserves for Winter Storm Uri as of June 30, 2021 are adequate, we continue to closely monitor reported claims and will adjust our estimates of gross and net losses as new information becomes available.

Additionally, our estimate of ultimate net losses and loss adjustment expenses directly attributed to COVID-19, as described in our 2020 Annual Report on Form 10-K in "Underwriting Results" under Item 7 Management's Discussion and Analysis of Financial Condition and Results of Operations, is based on assumptions about coverage, liability and reinsurance, for which significant uncertainty still exists, and represents our best estimate as of June 30, 2021 based upon information currently available. We continue to closely monitor reported claims, government actions, judicial decisions and changes in the levels of worldwide social disruption and economic activity arising from the pandemic and will adjust our estimates of gross and net losses as new information becomes available. Such adjustments to our reserves for COVID-19 losses and loss adjustment expenses may be material to the Company's results of operations, financial condition and cash flows.

Premiums

The increase in gross premium volume in our Insurance segment for both the quarter and six months ended June 30, 2021 was driven by growth across several product lines, most notably within our professional liability and general liability product lines, which experienced higher new business volume and benefited from more favorable rates. Net retention of gross premium volume was 82% for the quarters ended June 30, 2021 and 2020 and 83% for the six months ended June 30, 2021 and 2020. The increase in earned premiums for the quarter and six months ended June 30, 2021 was primarily due to the higher gross premium volume.

Combined Ratio: Quarter-to-Date

The decrease in the Insurance segment's current accident year loss ratio for the quarter ended June 30, 2021 compared to the same period of 2020 was primarily attributable to lower attritional loss ratios within our general liability, property and professional liability product lines, primarily due to the benefit of achieving higher premium rates.

The Insurance segment's combined ratio for the quarter ended June 30, 2021 included $154.5 million of favorable development on prior accident years loss reserves compared to $151.2 million for the same period of 2020. Higher earned premiums in 2021 compared to 2020 had an unfavorable impact on the prior accident years loss ratio, which more than offset the benefit of more favorable prior year loss development in 2021 compared to 2020. The increase in favorable development reflects more favorable development on our professional liability product lines in 2021 compared to 2020, which was offset by less favorable development on our personal lines and workers' compensation product lines in 2021 compared to 2020. For the quarter ended June 30, 2021, favorable development was most significant on our general liability, professional liability and workers' compensation product lines across several accident years and property product lines, primarily on the 2020 accident year. The favorable development on prior years loss reserves in the second quarter of 2020 was most significant on our general liability and workers' compensation product lines.

Table of Contents

The decrease in the Insurance segment's expense ratio for the quarter ended June 30, 2021 compared to the same period of 2020 was primarily due to the favorable impact of higher earned premiums and a lower policy acquisition cost ratio, mostly offset by higher profit sharing expenses in 2021 compared to 2020 as a result of improved profitability.

Combined Ratio: Year-to-Date

The Insurance segment's current accident year losses and loss adjustment expenses for the six months ended June 30, 2021 included $42.9 million of net losses and loss adjustment expenses from Winter Storm Uri. Current accident year losses for the six months ended June 30, 2020 included $293.0 million of net losses and loss adjustment expenses attributed to COVID-19. Excluding these losses attributed to Winter Storm Uri and COVID-19, the decrease in the current accident year loss ratio for the six months ended June 30, 2021 compared to the same period of 2020 was primarily attributable to lower attritional loss ratios within our professional liability, general liability and property product lines, primarily due to the benefit of achieving higher premium rates.

The Insurance segment's combined ratio for the six months ended June 30, 2021 included $273.6 million of favorable development on prior accident years loss reserves compared to $267.3 million for the same period of 2020. Higher earned premiums in 2021 compared to 2020 had an unfavorable impact on the prior accident years loss ratio, which more than offset the benefit of more favorable prior year loss development in 2021 compared to 2020. The increase in favorable development was primarily due to more favorable development on our property and general liability product lines in 2021 compared to 2020, mostly offset by less favorable development on our professional liability and workers' compensation product lines in 2021 compared to 2020. For the six months ended June 30, 2021, favorable development was most significant on our general liability, workers' compensation and professional liability product lines across several accident years, marine and energy product lines, primarily on the 2018 to 2020 accident years, and property product lines, primarily on the 2020 accident year. The favorable development on prior years loss reserves in 2020 was most significant on our professional liability, general liability and workers' compensation product lines.

The decrease in the Insurance segment's expense ratio for the six months ended June 30, 2021 compared to the same period of 2020 was primarily due to the favorable impact of higher earned premiums and a lower policy acquisition cost ratio, partially offset by higher profit sharing expenses in 2021 compared to 2020 as a result of improved profitability.

Premiums

The increase in gross premium volume in our Reinsurance segment for the quarter ended June 30, 2021 was driven by higher gross premiums within our general liability, professional liability and credit and surety product lines, partially offset by lower gross premiums within our property product lines. Higher gross premiums within our general liability and professional liability product lines were primarily due to increased exposures arising from growth in underlying portfolios and improved pricing on renewals. Higher gross premiums within our credit and surety product lines were primarily due to a favorable impact from the timing of renewals. Significant variability in gross premium volume can be expected in our Reinsurance segment due to individually significant contracts and multi-year contracts.

The increase in gross premium volume in our Reinsurance segment for the six months ended June 30, 2021 was primarily attributable to new business and increases on renewals, as previously discussed, within our general liability and professional liability product lines, partially offset by lower gross premiums within our property product lines.

Lower gross premiums within our property product lines for both the quarter and six months ended June 30, 2021 were primarily attributable to non-renewals following our decision to discontinue writing property reinsurance business on a risk-bearing basis effective January 1, 2021. We continue to have property loss exposure, including catastrophe exposure, on property treaties written in prior years with contract terms that extend beyond January 1, 2021 and on our retrocessional reinsurance property business.

Net retention of gross premium volume for the quarter ended June 30, 2021 was 92% compared to 85% for the same period of 2020. Net retention of gross premium volume for the six months ended June 30, 2021 was 93% compared to 87% for the same period of 2020. The increase in net retention was driven by changes in mix of business resulting from the changes in gross premium volume. The new business in our general liability and professional liability product lines was fully retained while the non-renewed property business had a lower retention rate than the rest of the segment.

Table of Contents

The increase in earned premiums for both the quarter and six months ended June 30, 2021 was primarily attributable to growth in gross premium volume within our general liability product lines in recent periods, partially offset by the impact of lower gross premiums within our property product lines as a result of our decision to discontinue writing property reinsurance business, as previously discussed.

Combined Ratio: Quarter-to-Date

The increase in the Reinsurance segment's current accident year loss ratio for the quarter ended June 30, 2021 compared to the same period of 2020 was primarily attributable to less favorable premium adjustments on prior accident years in 2021 compared to 2020 within our professional liability product lines, partially offset by the benefit of lower ceded reinsurance costs in 2021 compared to 2020 within our property product lines. As we are no longer writing property reinsurance business in our Reinsurance segment effective January 1, 2021, earned premiums and exposures on this business are beginning to trend down and will ultimately trend significantly lower in 2021 than 2020 and we modified our ceded reinsurance structures accordingly.

The Reinsurance segment's combined ratio for the quarter ended June 30, 2021 included $21.7 million of adverse development on prior accident years loss reserves, which was primarily attributable to our property product lines, as well as additional exposure recognized related to net favorable premium adjustments on our professional liability product lines, as previously discussed. For the quarter ended June 30, 2021 our property product lines reflected modest net adverse development on catastrophes that occurred in 2018 and 2017, as well as an increase in reserves directly attributed to COVID-19 following changes in the allocation of ceded reinsurance recoveries on our enterprise aggregate treaty between the Insurance segment and Reinsurance segment. There were no changes in our gross or net estimates of losses and loss adjustment expenses attributed to COVID-19 on a consolidated basis during the quarter ended June 30, 2021. For the quarter ended June 30, 2020, the combined ratio included $12.3 million of favorable development on prior accident years loss reserves, which was most significant on our property and general liability product lines, partially offset by additional exposure recognized related to net favorable premium adjustments on our professional liability product lines, as previously discussed.

The decrease in the Reinsurance segment's expense ratio for the quarter ended June 30, 2021 compared to the same period of 2020 was primarily attributable to lower compensation and general expenses due to the discontinuation of our property reinsurance business as well as the favorable impact of higher earned premiums in 2021 compared to 2020.

Combined Ratio: Year-to-Date

The Reinsurance segment's current accident year losses and loss adjustment expenses for the six months ended June 30, 2021 included $25.0 million of net losses and loss adjustment expenses from Winter Storm Uri. Current accident year losses for the six months ended June 30, 2020 included $32.0 million of net losses and loss adjustment expenses attributed to COVID-19. Excluding these losses attributed to Winter Storm Uri and COVID-19, the decrease in the current accident year loss ratio for the six months ended June 30, 2021 compared to the same period of 2020 was primarily attributable to our property product lines, consistent with the quarter-to-date variances previously discussed.

The Reinsurance segment's combined ratio for the six months ended June 30, 2021 included $50.4 million of adverse development on prior accident years loss reserves, which was primarily attributable to our property product lines, as well as additional exposure recognized related to net favorable premium adjustments on our professional liability product lines. Adverse development on our property product lines was primarily attributable an increase in reserves directly attributed to COVID-19 during the first quarter, reflecting changes in our estimates resulting from updated and new loss information from cedents. We also had net adverse development within our property product lines on catastrophes that occurred in recent years. For the six months ended June 30, 2020, the combined ratio included $1.6 million of adverse development on prior accident years loss reserves, which reflects adverse development and additional exposure recognized on net favorable premium adjustments on our professional liability product lines, mostly offset by favorable development on our property product lines.

The decrease in the Reinsurance segment's expense ratio for the six months ended June 30, 2021 compared to the same period of 2020 was primarily attributable to lower compensation and general expenses due to the discontinuation of our property reinsurance business as well as the favorable impact of higher earned premiums in 2021 compared to 2020.

(1) The change in net unrealized gains on available-for-sale securities included an increase related to an adjustment to our life and annuity benefit reserves of $0.9 million and $50.3 million for the quarter and six months ended June 30, 2021, respectively, and a decrease related to an adjustment to our life and annuity benefit reserves of $22.7 million and $35.6 million for the quarter and six months ended June 30, 2020, respectively. See note 8 of the notes to consolidated financial statements for details of our life and annuity benefit reserve adjustments.

(2) Investment yield reflects net investment income as a percentage of monthly average invested assets at amortized cost.

The increase in net investment income for both the quarter and six months ended June 30, 2021 compared to the same periods of 2020 was driven primarily by an increase in income on our equity method investments in 2021 compared to 2020. This increase was partially offset by lower interest income on our short-term investments due to lower short-term interest rates during the quarter and six months ended June 30, 2021 compared to the same periods of 2020. See note 3(d) of the notes to consolidated financial statements for details regarding the components of net investment income.

Net investment gains for both the quarter and six months ended June 30, 2021 were primarily attributable to an increase in the fair value of our equity portfolio driven by favorable market value movements. Net investment gains for the quarter ended June 30, 2020 were also primarily attributable to an increase in the fair value of our equity portfolio driven by favorable market value movements. This followed significant declines in the fair value of our equity portfolio in the first quarter of 2020 driven by unfavorable market value movements resulting from the onset of the COVID-19 pandemic. See note 3(e) of the notes to consolidated financial statements for further details on the components of net investment gains (losses).

The increase in net unrealized gains on available-for-sale investments for the quarter ended June 30, 2021 was primarily attributable to an increase in the fair value of our fixed maturity investment portfolio as a result of a decrease in interest rates during the period. This followed an increase in interest rates during the first quarter of 2021, resulting in an overall net decrease in the fair value of our fixed maturity investment portfolio for the six months ended June 30, 2021. The increase in net unrealized gains on available-for-sale investments for the quarter and six months ended June 30, 2020 was primarily attributable to increases in the fair value of our fixed maturity investment portfolio as a result of decreases in interest rates during the first half of 2020.

Table of Contents

We also evaluate our investment performance by analyzing taxable equivalent total investment return, which is a non-GAAP financial measure. Taxable equivalent total investment return includes items that impact net income, such as coupon interest on fixed maturity securities, changes in fair value of equity securities, dividends on equity securities and realized investment gains or losses on available-for-sale securities, as well as changes in unrealized gains or losses on available-for-sale securities, which do not impact net income. Certain items that are included in net investment income have been excluded from the calculation of taxable equivalent total investment return, such as amortization and accretion of premiums and discounts on our fixed maturity portfolio, to provide a comparable basis for measuring our investment return against industry investment returns. The calculation of taxable equivalent total investment return also includes the current tax benefit associated with income on certain investments that is either taxed at a lower rate than the statutory income tax rate or is not fully included in U.S. taxable income. We believe the taxable equivalent total investment return is a better reflection of the economics of our decision to invest in certain asset classes. We focus on our long-term investment return, understanding that the level of investment gains or losses may vary from one period to the next.

The following table reconciles investment yield to taxable equivalent total investment return.

Markel Ventures

Our Markel Ventures segment includes a diverse portfolio of businesses from different industries that offer various types of products and services to businesses and consumers, predominantly in the United States. We measure Markel Ventures' results by its operating income and net income, as well as earnings before interest, income taxes, depreciation and amortization (EBITDA). We consolidate the results of our Markel Ventures subsidiaries on a one-month lag, with the exception of any significant transactions or events that occur in the intervening period.

The following table summarizes the operating revenues, operating income, EBITDA and net income to shareholders from our Markel Ventures segment.


	Quarter Ended June 30,						Six Months Ended June 30,
(dollars in thousands)	2021		2020		% Change		2021		2020		% Change
Operating revenues	$	1,075,506	$	678,139	59	%	$	1,782,108	$	1,189,360	50	%
Operating income	$	108,665	$	79,404	37	%	$	160,128	$	121,161	32	%
EBITDA	$	138,357	$	105,272	31	%	$	219,535	$	172,732	27	%
Net income to shareholders	$	68,551	$	42,242	62	%	$	101,234	$	59,981	69	%

The increase in operating revenues for the quarter and six months ended June 30, 2021 compared to the same periods of 2020 was driven by increases of $244.6 million and $484.4 million, respectively, from our construction services businesses due to an increased contribution from Lansing, which was acquired in April 2020. Additionally, operating revenues for both periods increased across our consumer and building products businesses, equipment manufacturing businesses and transportation-related businesses, due in part to lower sales volumes at most of these businesses in 2020 as a result of the economic and social disruption caused by the COVID-19 pandemic, as well as further increases in demand within our consumer and building products businesses reflecting increases in consumer spending. These increases were partially offset by lower operating revenues at our healthcare businesses for both periods due to the sale of certain subsidiaries of one of our healthcare businesses in January 2021.

The increase in operating income, EBITDA and net income to shareholders for the quarter and six months ended June 30, 2021 compared to the same periods of 2020 was driven by the impact of higher sales volumes, as previously discussed, and the increased contribution of Lansing. For the six months ended June 30, 2021, the increase in operating income, EBITDA and net income to shareholders was also driven by a pre-tax transaction gain of $22.0 million in the first quarter of 2021, which was included in services and other expenses and recognized in connection with the sale of certain subsidiaries at one of our healthcare businesses, as previously discussed, as well as other associated changes in this business. For both the quarter and year to date periods, these favorable impacts in 2021 were partially offset by a $17.2 million pre-tax increase in our estimate of the contingent consideration obligations during the second quarter of 2021 related to recent acquisitions, a portion of which was paid during the quarter, and the impact of lower revenues and operating margins at one of our consulting services businesses in 2021 compared to 2020.

Markel Ventures EBITDA is a non-GAAP financial measure. We use Markel Ventures EBITDA as an operating performance measure in conjunction with U.S. GAAP measures, including operating revenues, operating income and net income to shareholders, to monitor and evaluate the performance of our Markel Ventures segment. Because EBITDA excludes interest, income taxes, depreciation and amortization, it provides an indicator of economic performance that is useful to both management and investors in evaluating our Markel Ventures businesses as it is not affected by levels of debt, interest rates, effective tax rates or levels of depreciation or amortization resulting from purchase accounting. The following table reconciles Markel Ventures operating income to Markel Ventures EBITDA.

Insurance-Linked Securities

Our insurance-linked securities operations include results from our Nephila operations, as well as start-up costs and operating expenses associated with Lodgepine. For the quarter ended June 30, 2021, the increase in operating revenues in our insurance-linked securities operations was due to growth in our third-party Nephila managing general agent operations. For the six months ended June 30, 2021, the decrease in operating revenues in our insurance-linked securities operations was driven by lower investment management fees at our Nephila operations due in part to lower average assets under management in the first half of 2021 compared to the first half of 2020, partially offset by growth in our third-party Nephila managing general agent operations. Nephila's net assets under management were $9.8 billion as of June 30, 2021.

Program Services and Other Fronting

For both the quarter and six months ended June 30, 2021, the increase in operating revenues in our program services and other fronting operations was primarily due to higher gross premium volume at our program services operations. Gross written premiums in our program services operations were $761.2 million and $1.4 billion for the quarter and six months ended June 30, 2021, respectively, compared to $591.2 million and $984.4 million for the quarter and six months ended June 30, 2020, respectively. The increase in gross premium volume was driven by the expansion of existing programs, as well as growth from new programs. Gross premium volume in the first quarter of 2020 was unfavorably impacted by the cancellation of an in-force book of policies related to a large program resulting in a one-time unfavorable premium adjustment of $55.0 million.

Interest Expense and Income Taxes

Interest Expense

Interest expense was $46.6 million and $89.0 million for the quarter and six months ended June 30, 2021, respectively, compared to $45.4 million and $90.5 million for the same periods of 2020.

Income Taxes

The effective tax rate was 21% for both the six months ended June 30, 2021 and 2020.

Comprehensive Income (Loss) to Shareholders and Book Value per Common Share

Comprehensive income (loss) to shareholders	$	849,654	$	1,092,393	$	1,208,651	$	(260,416)

Book value per common share increased 10% from $885.72 at December 31, 2020 to $974.45 as of June 30, 2021, primarily due to net income to shareholders for the six months ended June 30, 2021.

Financial Condition

Liquidity and Capital Resources

We seek to maintain prudent levels of liquidity and financial leverage for the protection of our policyholders, creditors and shareholders. Our debt to capital ratio was 23% at June 30, 2021 and 21% at December 31, 2020. The increase reflects an increase in senior long-term debt and other debt, primarily attributable to senior notes issued in May 2021.

In May 2021, we issued $600 million of 3.45% unsecured senior notes due May 2052 with net proceeds of $591.4 million, before expenses. See note 9 of the notes to consolidated financial statements for further information regarding our May 2021 debt offering.

Investments, cash and cash equivalents and restricted cash and cash equivalents (invested assets) were $27.3 billion and $24.9 billion at June 30, 2021 and December 31, 2020, respectively. The following table presents the composition of our invested assets.


	June 30, 2021		December 31, 2020
Fixed maturity securities	42	%	43	%
Equity securities	30	%	28	%
Short-term investments, cash and cash equivalents and restricted cash and cash equivalents	28	%	29	%
Total	100	%	100	%

Table of Contents

Our holding company had $4.9 billion and $4.1 billion of invested assets at June 30, 2021 and December 31, 2020, respectively. The increase is primarily due to net proceeds from our May 2021 debt offering. The following table presents the composition of our holding company's invested assets.


	June 30, 2021		December 31, 2020
Fixed maturity securities	5	%	7	%
Equity securities	43	%	45	%
Short-term investments, cash and cash equivalents and restricted cash and cash equivalents	52	%	48	%
Total	100	%	100	%

We have access to various capital sources, including dividends from certain of our insurance and Markel Ventures subsidiaries, holding company invested assets, undrawn capacity under our corporate revolving credit facility and access to the debt and equity capital markets. We believe that we have sufficient liquidity to meet our capital needs. However, the availability of these sources of capital and the availability and terms of future financings will depend on a variety of factors, and could be adversely affected by, among other things, risks and uncertainties related to the COVID-19 pandemic.

Cash Flows

Net cash provided by operating activities was $813.2 million for the six months ended June 30, 2021 compared to $488.7 million for the same period of 2020. The increase in net cash flows from operating activities for the six months ended June 30, 2021 was primarily driven by higher net premium volumes in our Insurance segment, partially offset by higher claims settlement activity across both of our underwriting segments.

Net cash used by investing activities was $2.2 billion for the six months ended June 30, 2021 compared to net cash provided by investing activities of $1.1 billion for the same period of 2020. During the six months ended June 30, 2021, net cash used by investing activities included net purchases of short-term investments of $1.2 billion and purchases of fixed maturity securities of $1.0 billion, net of proceeds from maturities and sales of fixed maturity securities. During the six months ended June 30, 2020, net cash provided by investing activities included $1.2 billion from net sales of equity securities, which was partially offset by $547.9 million of net cash used for the acquisition of Lansing. During the six months ended June 30, 2020, net cash provided by investing activities reflected several actions taken within our investment portfolio to increase our allocation to cash in response to uncertainties related to COVID-19. Cash flow from investing activities is affected by various factors such as anticipated payment of claims, financing activity, acquisition opportunities and individual buy and sell decisions made in the normal course of our investment portfolio management.

Net cash provided by financing activities was $564.3 million for the six months ended June 30, 2021, which included net proceeds of $591.4 million from our May 2021 debt offering, as previously discussed. We paid dividends of $18.0 million on our preferred shares during the six months ended June 30, 2021. Net cash provided by financing activities was $607.5 million for the six months ended June 30, 2020, which included net proceeds of $591.9 million from our May 2020 preferred shares offering. Cash of $60.8 million and $23.9 million was used to repurchase outstanding common shares of our stock during the first six months of 2021 and 2020, respectively.

Critical Accounting Estimates

Critical accounting estimates are those estimates that both are important to the portrayal of our financial condition and results of operations and require us to exercise significant judgment. The preparation of financial statements in accordance with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of material contingent assets and liabilities. These estimates, by necessity, are based on assumptions about numerous factors.

Our critical accounting estimates consist of estimates and assumptions used in determining the reserves for unpaid losses and loss adjustment expenses and life and annuity reinsurance benefit reserves as well as estimates and assumptions used in the valuation of goodwill and intangible assets. We review the adequacy of reserves for unpaid losses and loss adjustment expenses and life and annuity reinsurance benefit reserves quarterly. Estimates and assumptions for goodwill and intangible assets are reviewed in conjunction with acquisitions and goodwill and indefinite-lived intangible assets are reassessed for impairment at least annually or when events or circumstances indicate that their carrying value may not be recoverable. Actual results may differ materially from the estimates and assumptions used in preparing the consolidated financial statements.

Readers are urged to review our 2020 Annual Report on Form 10-K for a more complete description of our critical accounting estimates.

Safe Harbor and Cautionary Statement

This report contains statements concerning or incorporating our expectations, assumptions, plans, objectives, future financial or operating performance and other statements that are not historical facts. These statements are "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Such statements may use words such as "anticipate," "believe," "estimate," "expect," "intend," "predict," "project" and similar expressions as they relate to us or our management.

There are risks and uncertainties that may cause actual results to differ materially from predicted results in forward-looking statements. Factors that may cause actual results to differ are often presented with the forward-looking statements themselves. Additional factors that could cause actual results to differ from those predicted are set forth under "Business Overview," "Risk Factors," and "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our 2020 Annual Report on Form 10-K, or are included in the items listed below:

•our efforts to develop new products, expand in targeted markets or improve business processes and workflows may not be successful and may increase or create new risks (e.g., insufficient demand, change to risk exposures, distribution channel conflicts, execution risk, increased expenditures);

•the frequency and severity of man-made and natural catastrophes (including earthquakes, wildfires and weather-related catastrophes) may exceed expectations, are unpredictable and, in the case of wildfires and weather-related catastrophes, may be exacerbated if, as many forecast, changing conditions in the oceans and atmosphere result in increased hurricane, flood, drought or other adverse weather-related activity;

•we offer insurance and reinsurance coverage against terrorist acts in connection with some of our programs, and in other instances we are legally required to offer terrorism insurance; in both circumstances, we actively manage our exposure, but if there is a covered terrorist attack, we could sustain material losses;

•emerging claim and coverage issues, changing legal and social trends, and inherent uncertainties in the loss estimation process can adversely impact the adequacy of our loss reserves and our allowance for reinsurance recoverables;

•reinsurance reserves are subject to greater uncertainty than insurance reserves, primarily because of reliance upon the original underwriting decisions made by ceding companies and the longer lapse of time from the occurrence of loss events to their reporting to the reinsurer for ultimate resolution;

•inaccuracies (whether due to data error, human error or otherwise) in the various modeling techniques and data analytics (e.g., scenarios, predictive and stochastic modeling, and forecasting) we use to analyze and estimate exposures, loss trends and other risks associated with our insurance and insurance-linked securities businesses could cause us to misprice our products or fail to appropriately estimate the risks to which we are exposed;

•changes in the assumptions and estimates used in establishing reserves for our life and annuity reinsurance book (which is in runoff), for example, changes in assumptions and estimates of mortality, longevity, morbidity and interest rates, could result in material increases in our estimated loss reserves for such business;

•adverse developments in insurance coverage litigation or other legal or administrative proceedings could result in material increases in our estimates of loss reserves;

•initial estimates for catastrophe losses are often based on limited information, are dependent on broad assumptions about the nature and extent of losses, coverage, liability and reinsurance, and those losses may ultimately differ materially from our expectations;

•a number of additional factors may adversely affect our Markel Ventures operations, and the markets they serve, and negatively impact their revenues and profitability, including, among others: adverse weather conditions, plant disease and other contaminants; changes in government support for education, healthcare and infrastructure projects; changes in capital spending levels; changes in the housing and commercial construction markets; liability for environmental matters; volatility in the market prices for their products; and volatility in commodity prices and interest and foreign currency exchange rates.

Results from our underwriting, investing, Markel Ventures and other operations have been and will continue to be potentially materially affected by these factors. In addition, with respect to previously reported developments at Markel CATCo and the decision to place both the Markel CATCo Reinsurance Fund Ltd., a Bermuda exempted mutual fund company comprised of multiple segregated accounts, and Markel CATCo Re Ltd. (Markel CATCo Re) into run-off:

•the inquiries by the U.S. Department of Justice, U.S. Securities and Exchange Commission and Bermuda Monetary Authority into loss reserves recorded in late 2017 and early 2018 at Markel CATCo Re (the Markel CATCo Inquiries) may result in adverse findings, reputational damage, the imposition of sanctions, increased costs, litigation and other negative consequences; and

•management time and resources may be diverted to address the Markel CATCo Inquiries, as well as related litigation.

By making forward-looking statements, we do not intend to become obligated to publicly update or revise any such statements whether as a result of new information, future events or other changes. Readers are cautioned not to place undue reliance on any forward-looking statements, which speak only as at their dates.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market risk is the risk of economic losses due to adverse changes in the estimated fair value of a financial instrument as the result of changes in equity prices, interest rates, foreign currency exchange rates and commodity prices. Our consolidated balance sheets include assets and liabilities with estimated fair values that are subject to market risk. Our primary market risks are equity price risk associated with investments in equity securities, interest rate risk associated with investments in fixed maturity securities and foreign currency exchange rate risk associated with our international operations. Some businesses within our Markel Ventures operations are exposed to commodity price risk resulting from changes in the price of raw materials, parts and other components necessary to manufacture products, however, this risk is not material to the Company. The operating results of these businesses could be adversely impacted should they be unable to obtain price increases from customers in response to significant increases in raw materials, parts and other component prices. During the six months ended June 30, 2021, there were no material changes to the market risk components described in our Annual Report on Form 10-K for the year ended December 31, 2020.

Our fixed maturity portfolio includes corporate bonds, mortgage-backed securities and securities issued by municipalities, foreign governments and non-sovereign foreign institutions. Credit risk exists within our fixed maturity portfolio from the potential for loss resulting from adverse changes in an issuer's ability to repay its debt obligations. During the six months ended June 30, 2021, there were no material changes in our corporate bond, mortgage-backed security, municipal bond or foreign government fixed maturity holdings.

We believe that our fixed maturity portfolio is highly diversified and comprised of high quality securities. Our fixed maturity portfolio has an average rating of "AAA," with 99% rated "A" or better by at least one nationally recognized rating organization. Our policy is to invest in investment grade securities and to minimize investments in fixed maturity securities that are unrated or rated below investment grade. At June 30, 2021, less than 1% of our fixed maturity portfolio was unrated or rated below investment grade. Our fixed maturity portfolio includes securities issued with financial guaranty insurance. We purchase fixed maturity securities based on our assessment of the credit quality of the underlying assets without regard to insurance.

We also have credit risk to the extent any of our reinsurers are unwilling or unable to meet their obligations under our ceded reinsurance agreements. As of December 31, 2020, all of our ten largest reinsurers within our underwriting operations were rated "A" or better by A.M. Best and within our program services business, six of our ten largest reinsurers were rated "A" or better by A.M. Best. For reinsurers within our program services business with a credit rating of lower than "A" we employ a stringent collateral monitoring program, under which the majority of the reinsurance recoverable balances are fully collateralized. During the six months ended June 30, 2021, there were no material changes to the credit ratings of our top ten reinsurers within our underwriting and program services operations as reported in our Annual Report on Form 10-K for the year ended December 31, 2020.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this quarterly report, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures (Disclosure Controls), as defined under Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934 (Exchange Act). This evaluation was conducted under the supervision and with the participation of our management, including the Co-Principal Executive Officers (Co-PEOs) and the Principal Financial Officer (PFO).

Based upon this evaluation, the Co-PEOs and PFO concluded that effective Disclosure Controls were in place to ensure that the information required to be disclosed in reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the second quarter of 2021 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
