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 and programs.~~products. Through its ~~wholly-owned~~wholly owned subsidiary, Markel Ventures, Inc. (Markel Ventures), Markel Corporation also owns interests in various businesses that operate outside of the specialty insurance marketplace.

a)Basis of Presentation. The consolidated balance sheet as of September 30, ~~2018~~2019 and the related consolidated statements of income ~~(loss)~~ and comprehensive income ~~(loss)~~and changes in equity for the quarters and nine months ended September 30, ~~2018~~2019 and ~~2017,~~2018, and the consolidated statements of ~~changes in equity and~~ cash flows for the nine months ended September 30, ~~2018~~2019 and ~~2017~~2018 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, ~~2017~~2018 was derived from Markel Corporation's audited annual consolidated financial statements.

The accompanying consolidated financial statements have been prepared in accordance with ~~U.S.~~United States (U.S.) generally accepted accounting principles ~~(U.S. GAAP)~~(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 year amounts have been reclassified to conform to the current 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 ~~2017~~2018 Annual Report on Form 10-K for a more complete description of the Company's business and accounting policies.

b)~~Foreign Currency Transactions.~~ ~~The U.S. Dollar is~~Leases. Following the ~~Company’s reporting currency and the primary functional currency~~adoption of its foreign underwriting operations. The functional currencies of the Company's other foreign operations are the currencies of the primary economic environments in which the majority of their business is transacted.

Foreign currency transaction gains and losses are the result of exchange rate changes on transactions denominated in currencies other than the functional currency at each foreign entity. Monetary assets and liabilities are remeasured to the functional currency at current exchange rates, with resulting gains and losses included in net foreign exchange losses (gains) within net income. Non-monetary assets and liabilities are remeasured to the functional currency at historic exchange rates. Available-for-sale securities are recorded at fair value with resulting gains and losses, including the portion attributable to movements in exchange rates, included in the change in net unrealized gains on available-for-sale investments, net of taxes within other comprehensive income. While we attempt to naturally hedge our exposure to foreign currency fluctuations by matching assets and liabilities in currency, there is a financial statement mismatch between the gains or losses recorded in net income related to insurance reserves denominated in non-functional currencies and the gains or losses recorded in other comprehensive income related to the available-for-sale securities supporting the reserves.

Assets and liabilities of foreign operations denominated in a functional currency other than the U.S. Dollar are translated into the U.S. Dollar at current exchange rates, with resulting gains or losses included, net of taxes, in the change in foreign currency translation adjustments within other comprehensive income.

Historically, the Company also designated certain additional currencies, including the British Pound Sterling, the Euro, and the Canadian Dollar, as functional currencies within its foreign underwriting operations that were deemed to contain distinct and separable operations in those foreign economic environments. However, over time the Company’s foreign underwriting operations have evolved and are now managed on a global basis. Effective January 1, 2018, management reassessed its functional currency determination as required by Financial Accounting Standards Board (FASB) Accounting Standards ~~Codification (ASC) 830,~~ ~~Foreign Currency Matters~~, and concluded that its foreign underwriting operations have evolved to function as an extension, or integral component, of the Company’s global underwriting operations, and are no longer deemed to contain distinct and separable operations. As a result, more foreign currency denominated transactions are designated as non-functional, with related remeasurement gains and losses included in net income. The change in the Company’s functional currency determination has been applied on a prospective basis in accordance with ASC 830. Therefore, any translation gains and losses that were previously recorded in accumulated other comprehensive income through December 31, 2017 remain unchanged as of September 30, 2018.

c)~~Revenue Recognition.~~ ~~Effective January 1, 2018, the Company adopted FASB Accounting Standards~~ Update (ASU) No. ~~2014-09,~~ ~~Revenue from Contracts~~2016-02, Leases (Topic 842), effective January 1, 2019, the present value of future lease payments for the Company’s leases with ~~Customers (Topic 606),~~ terms greater than 12 months are included on the consolidated balance sheet as lease liabilities and ~~related amendments, which created a new comprehensive revenue recognition standard, ASC 606,~~right-of-use lease assets.

The Company’s lease portfolio primarily consists of operating leases for real estate. Total expected lease payments are based on the lease payments specified in the contract and the stated term, including any options to extend or terminate that ~~serves~~the Company is reasonably certain to exercise. The Company has elected the practical expedient to account for lease components and any associated non-lease components as a single ~~source~~lease component, and therefore allocates all of ~~revenue guidance for all contracts with customers to transfer goods or services or contracts for~~ the ~~transfer of nonfinancial assets, unless those contracts are within the scope of other standards, such as insurance contracts. ASC 606 is not applicable~~expected lease payments to the ~~Company's insurance premium revenues or revenues from its investment portfolio but is applicable~~lease component.

The lease liability, which represents the Company’s obligation to ~~most of the Company's other revenues, as described below. See note 2 for further discussion of the impact of adopting this standard.~~

~~Other revenues primarily relate to the Company's Markel Ventures segment and consist of revenues~~make lease payments arising from the ~~sale of products and services. Revenues are recognized when, or as, control of the promised goods or services~~lease, is transferred to the Company's customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. All contracts with customers either have an original expected length of one year or less or the Company recognizes revenue at the amount for which it has a right to invoice for the products delivered or services performed. Certain customers may receive volume rebates or credits for products and services, which are accounted for as variable consideration. The Company estimates these amountscalculated based on the present value of expected ~~amount to be provided to the customer and reduces revenues recognized by a corresponding amount. The Company does not expect significant changes to its estimates of variable consideration~~lease payments over the remaining lease term, ofdiscounted using the ~~contracts.~~

~~Payment terms~~Company’s collateralized incremental borrowing rate at the commencement date. The lease liability is then adjusted for ~~products~~any prepaid rent, lease incentives received or capitalized initial direct costs to determine the lease asset, which represents the Company's right to use the underlying asset for the lease term. Lease liabilities and services vary by the type of product or service offered and the location of the customer, and payment is typically received at or shortly after the point of sale. For certain products, the Company requires partial payment in the form of a deposit before the productslease assets are ~~delivered to the customer, which is~~ included in other liabilities and other assets, respectively, on the ~~Company's~~ consolidated balance sheet.

~~Product revenues~~Total lease costs are primarily ~~generated from the sale~~comprised of ~~ornamental plants, equipment used in baking systems, portable dredges,~~rental expense for operating leases. Rental expense is recognized on a straight line basis over the ~~road transportation equipment, flooring for the trucking industry,~~lease term and ~~residential homes. Most~~includes amortization of the ~~Company's product revenues are recognized when~~right-of-use lease asset and imputed interest on the ~~products are shipped~~lease liability. Rental expense attributable to the ~~customer or the products arrive at the agreed upon destination with the end customer. Some of~~Company's underwriting operations is included in underwriting, acquisition and insurance expenses and rental expense attributable to the Company's ~~contracts include multiple performance obligations. For such arrangements, revenues are allocated to each performance obligation based on the relative standalone selling price, which~~other operations is ~~derived from amounts stated~~included in products expenses and services and other expenses in the ~~contract.~~

~~Service revenues are primarily generated by delivering healthcare services, retail intelligence, consulting services~~consolidated statements of income and investment management services. Service revenues are generally recognized over the term of the contracts based on hours incurred or as services are provided. Investment management fee income is recognized over the period in which investment management services are provided and is calculated and recognized monthly based on the net asset value of the accounts managed. In connection with the investment management services provided, the Company is also entitled to participate, on a fixed-percentage basis, in any net income generated in excess of an agreed-upon threshold as established by the underlying investment management agreements. In general, net income is calculated at the end of each calendar year and performance fees are payable annually. Performance fee income is recognized at the conclusion of the contractual performance period, when the uncertainty related to performance has been resolved.

comprehensive income.

2. Recent Accounting Pronouncements

Effective January 1, ~~2018,~~2019, the Company adopted FASB ASU No. ~~2014-09,~~ ~~Revenue from Contracts with Customers~~2016-02, Leases (Topic ~~606)~~ 842) and several other ~~ASU’s~~ASUs that were issued as amendments to ASU No. ~~2014-09,~~2016-02, which apply to all contracts with customers to transfer goods or services or for the transfer of nonfinancial assets, unless those contracts are within the scope of other standards. ASU No. 2014-09's core principle is that a company recognizes revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In adopting this standard, the Company is required to use more judgment and make more estimates than under the previous guidance, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. The Company adopted ASU No. 2014-09 using the modified retrospective method. Prior periods were not restated and a cumulative-effect adjustment of applying the new standard to all open contracts at January 1, 2018 was $0.3 million, and is included as an adjustment to 2018 beginning retained earnings. The Company's other revenues for the quarter and nine months ended September 30, 2018 and its receivables, other assets and other liabilities as of September 30, 2018 were not materially different from the amounts that would have been recognized under the previous guidance. ASU No. 2014-09 also requires expanded revenue disclosures which are included in note 8.

~~Effective January 1, 2018, the Company adopted ASU No. 2016-01,~~ ~~Financial Instruments (Topic 825): Recognition and Measurement of Financial Assets and Financial Liabilities~~. As a result of adoption of this ASU, equity instruments that do not result in consolidation and are not accounted for under the equity method are measured at fair value and any changes in fair value are recognized in net income. Previously, the Company’s equity securities were classified as available-for-sale and changes in fair value were recorded in other comprehensive income. Upon adoption of this ASU, cumulative net unrealized gains on equity securities of $2.6 billion, net of deferred income taxes of $684.4 million, were reclassified from accumulated other comprehensive income into retained earnings. Prior periods have not been restated to conform to the current presentation. See note 4(e) for details regarding the change in net unrealized gains on equity securities included in net income for the quarter and nine months ended September 30, 2018 and included in other comprehensive income for the quarter and nine months ended September 30, 2017.

~~Effective January 1, 2018, the Company early adopted ASU No. 2018-02,~~ ~~Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.~~ The ASU provides an option to reclassify tax effects remaining in accumulated other comprehensive income as a result of the Tax Cuts and Jobs Act (TCJA) to retained earnings. Upon enactment of the TCJA, the U.S. corporate tax rate was reduced from 35% to 21% and the Company's U.S. deferred tax balances were remeasured to the lower enacted U.S. corporate tax rate. U.S. GAAP requires the effects of changes in tax rates and laws on deferred tax balances to be recorded as a component of income tax expense in the period of enactment, even if the assets and liabilities relate to items of accumulated other comprehensive income. As a result of adopting the ASU, the Company reclassified $401.5 million of previously recognized deferred taxes from accumulated other comprehensive income into retained earnings as of January 1, 2018.

The following ASUs relate to topics relevant to the Company's operations and were adopted effective January 1, 2018. These ASUs did not have a material impact on the Company’s financial position, results of operations or cash flows:

~~ASU No. 2016-16,~~ ~~Income Taxes (Topic 740): Intra-entity Transfers of Assets Other Than Inventory~~

~~ASU No. 2017-07,~~ ~~Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost~~

~~ASU No. 2017-09,~~ ~~Stock Compensation (Topic 718): Scope of Modification Accounting~~

~~In February 2016, the FASB issued ASU No. 2016-02,~~ ~~Leases (Topic 842). The ASU requires~~require lessees to record most leases onin their balance sheets as a lease liability with a corresponding right-of-use asset, but continue to recognize the related ~~leasing~~rent expense within net income. The ~~FASB subsequently issued ASUs with improvements to the guidance, including ASU No. 2018-11,~~ ~~Leases (Topic 842): Targeted Improvements, which provides entities with an additional transition method~~Company elected to apply the ~~new standard.

The ~~ASUs become effective for~~Company continues to apply the previous guidance to 2018 and prior periods. The Company also elected the package of practical expedients permitted under the transition guidance within the new standard, which, among other things, allowed companies to carry forward their historical lease classification. As a result of adopting ASU No. 2016-02, the Company ~~during the first quarter~~recorded a right-of-use lease asset and a lease liability of ~~2019~~$243.7 million and ~~will be applied using a modified retrospective approach.

In June 2016, the FASB issued ASU No. 2016-13, Financial ~~Instruments -~~ Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The FASB subsequently issued several ASUs as amendments to ASU No. 2016-13. The standard replaces the current incurred loss model used to measure impairment losses with ana current expected credit loss (CECL) model for ~~trade, reinsurance, and other receivables as well as~~ financial instruments measured at amortized ~~cost.~~cost, including reinsurance recoverables and trade receivables. For available-for-sale ~~debt securities,~~fixed maturities, which are measured at fair value, the ASU requires entities to record impairments as an allowance, rather than a reduction of the amortized cost, as is currently required under the other-than-temporary impairment model. ASU No. 2016-13 becomes effective for the Company during the first quarter of 2020 and will be applied using a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of ~~the beginning of the first reporting period in which the guidance is effective.~~January 1, 2020. The Company is currently evaluating ASU No. 2016-13 to determine the potential impact that adopting this standard will have on its consolidated financial statements. Application of the ~~new expected loss~~CECL model ~~for measuring impairment losses~~ will not impact the Company's investment portfolio, none of which is measured at amortized cost, but will impact certain of the Company's other financial assets, including its reinsurance ~~recoverables.~~recoverables and receivables. Upon adoption of this ASU, any impairment losses on the Company's available-for-sale ~~debt securities~~fixed maturities will be recorded as an allowance, subject to reversal, rather than as a reduction in amortized cost.

In August 2018, the FASB issued ASU No. 2018-12, Financial ~~Services-Insurance~~Services—Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts. The ASU requires insurance entities with long duration contracts to: (1) review and, if there is a change, update the assumptions used to measure cash flows at least annually, as well as update the discount rate assumption at each reporting date; (2) measure all market risk benefits associated with deposit (or account balance) contracts at fair value; and (3) disclose liability rollforwards and information about significant inputs, judgments, assumptions and methods used in measurement, including changes thereto and the effect of those changes on measurement. In August 2019, the FASB proposed an update to ASU No. 2018-12 ~~becomes~~to defer its effective date. The proposed update would make the ASU effective for the Company during the first quarter of ~~2021. The~~2022. ASU No. 2018-12 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.

In August 2018, the FASB issued ASU No. 2018-15, ~~Intangibles-Goodwill~~Intangibles—Goodwill and ~~Other-~~ Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The ASU aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software and hosting arrangements that include an internal-use software license. The ASU requires an entity to expense the ~~capitalized~~ implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement. Currently, such costs are generally expensed as incurred. ASU No. 2018-15 becomes effective for the Company during the first quarter of 2020 and may be applied on a prospective or retrospective basis. Early adoption is permitted. The Company is currently evaluating ~~ASU No. 2018-15~~its information technology projects to determine the impact that adopting ~~this standard~~ASU No. 2018-15 will have on its consolidated financial statements.

The following ASUs issued by the FASB are relevant to the Company's operations and are not yet effective. These ASUs are not expected to have a material impact on the Company's financial position, results of operations or cash flows:


•	ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement

⁽¹⁾	Effective January 1, 2018, the Company adopted ASU No. 2016-01 and equity securities are no longer classified as available-for-sale. Prior periods have not been restated to conform to the current presentation. See note 2.

At December 31, ~~2017,~~2018, the Company held ~~739~~1,005 securities with a total estimated fair value of ~~$2.8~~$4.6 billion and gross unrealized losses of ~~$57.3~~$134.0 million. Of these ~~739~~1,005 securities, ~~272~~541 securities had been in a continuous unrealized loss position for one year or longer and had a total estimated fair value of ~~$1.5~~$2.0 billion and gross unrealized losses of ~~$34.3~~$77.5 million. ~~Of these securities, 258 securities were fixed maturities and 14 were equity securities.~~

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 deemed other-than-temporary. 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 other-than-temporary impairment, including the length of time and the extent to which fair value has been below cost and the financial condition and near-term prospects of the issuer.

For fixed maturities, the Company considers whether it intends to sell the security or if it is more likely than not that it will be required to sell the security before recovery, the implied yield-to-maturity, the credit quality of the issuer and the ability to recover all amounts outstanding when contractually due. For fixed maturities where the Company intends to sell the security or it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost, a decline in fair value is considered to be other-than-temporary and 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. If the decline in fair value of a fixed maturity below its amortized cost is considered to be other-than-temporary based upon other considerations, 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-related portion of the other-than-temporary impairment, which is recognized in net income, resulting in a new cost basis for the security. Any remaining decline in fair value represents the non-credit portion of the other-than-temporary impairment, which is recognized in other comprehensive income. The discount rate used to calculate the estimated present value of the cash flows expected to be collected is the effective interest rate implicit for the security at the date of purchase. When assessing whether it intends to sell a fixed maturity or if it is likely to be required to sell a fixed maturity before recovery of its amortized cost, the Company evaluates facts and circumstances including decisions to reposition the investment portfolio, potential sales of investments to meet cash flow needs and, ultimately, current market prices.

Prior to the adoption of ASU No. 2016-01, equity securities were considered available-for-sale and were included in the analysis of other than temporary impairments. For equity securities, the ability and intent to hold the security for a period of time sufficient to allow for anticipated recovery was considered. A decline in fair value of equity securities that was considered to be other-than-temporary was 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.

5. Fair Value Measurements

~~ASC 820-10,~~ Accounting Standards Codification (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.

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.

~~Investments available-for-sale~~Available-for-sale investments and equity securities. ~~Equity~~ Available-for-sale investments and equity securities ~~and available-for-sale investments~~ are recorded at fair value on a recurring basis. Available-for-sale investments include fixed maturities 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 ~~available-for-sale~~ 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 maturities 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 ~~(ILS 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 ~~11,~~14 (the Markel CATCo Funds), and are valued using unobservable inputs.

Fair value for available-for-sale investments ~~available-for-sale~~ 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 maturities are classified as Level 2 investments. The fair value of fixed maturities is normally derived through recent reported trades for identical or similar securities, making adjustments through the reporting date based upon available market observable data described above. If there are no recent reported trades, the fair value of fixed maturities 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 ~~ILS~~Markel CATCo Funds, these investments are classified as Level 3 within the fair value hierarchy. ~~Changes in fair value of the ILS Funds are included in the change in fair value of equity securities in net income.~~ 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 ~~ILS~~Markel CATCo Funds invest. Significant unobservable inputs used in the valuation of these investments include an adjustment to include the fair value of the equity that was issued by one of the Markel CATCo Funds in exchange for notes receivable, rather than cash, which is excluded from NAV. The determination of fair value of the securities also considers external market data, including the trading price relative to its NAV of CATCo Reinsurance Opportunities Fund Ltd. (CROF), a comparable security traded on a market operated by the London Stock Exchange and on the Bermuda Stock Exchange further described in note 14. Generally, the Company's investments in the ~~ILS~~Markel CATCo Funds are redeemable annually as of January 1^st of each calendar year. However, in years with significant loss events on the underlying securitized reinsurance contracts, as was the case in 2018 and 2017, payment for the redemption of certain investments may be restricted ~~from redemption~~ for up to three years.

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, which includes the price of a comparable security and an insurance-linked security index.~~data.

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.

6. Segment Reporting Disclosures

In conjunction with the Company's continued growth and diversification, beginning in the first quarter of 2018 the Company's chief operating decision maker changed the way it reviews the Company's ongoing underwriting results. Effective January 1, 2018, theThe Company's chief operating decision maker reviews the Company's ongoing underwriting operations on a global basis in the following ~~two~~2 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 across the Company. The Reinsurance segment includes all treaty reinsurance written across the Company. All investing activities related to the Company's underwriting operations are included in the Investing segment.

Also during the first quarter of 2018, the Company's chief operating decision maker changed the way it assesses the performance of and allocates resources to its Markel Ventures operations. Historically, the Company’s chief operating decision maker reviewed and assessed the performance of each Markel Ventures business separately with no single business being individually significant. Following the continued growth in the Company’s Markel Ventures operations, effective in the first quarter of 2018, 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 chief operating decision maker reviews and assesses Markel Ventures’ performance in the aggregate, as a single operating segment.

~~The following table summarizes revenue from the Markel Ventures segment by major product grouping.~~

The Company's other operations include the results of the Company's ~~legal and professional consulting~~program services business and the results of the Company's ~~investment management services~~insurance-linked securities operations attributable to ~~Markel CATCo Investment Management Ltd. Also included in the~~MCIM and, beginning November 2018, Nephila. The Company's other operations ~~are~~also include results ~~attributable to the run-off of acquired managing general agent operations and~~for underwriting ~~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. ~~Effective November 17, 2017, the Company's other operations also include the results of the program services business acquired as part of the State National transaction.~~ For purposes of segment reporting, none of the Company's 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 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,~~ investing and Markel Ventures segments and certain of its other operations, including its program services and insurance-linked securities 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 ~~all assets~~ not specifically ~~allocated to the Investing or Markel Ventures segments, or~~attributed to the Company's other operations. Underwriting and investing assets are not allocated to the ~~Insurance and Reinsurance~~Company's underwriting segments since the Company does not manage its assets by underwriting segment. The Company does not allocate capital expenditures for long-lived assets to either of its underwriting segments for management reporting purposes.

a)The following tables summarize the Company's segment disclosures. ~~Prior year amounts have been recast for consistency with the current year presentation.~~

10.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 ~~2018 Catastrophes of $28.6 million. Ceded incurred losses and loss adjustment expenses for both~~investments supporting the policy benefit reserves would result in a reserve deficiency if those gains were realized. During the quarter and nine months ended September 30, ~~2017 included estimated ceded losses~~2019, the Company recognized a reserve deficiency resulting from a decrease in the market yield on the ~~2017 Catastrophes~~investment portfolio supporting the policy benefit reserves by increasing life and annuity benefits by $31.3 million and $93.1 million, respectively, and decreasing the change in net unrealized holding gains included in other comprehensive income by a corresponding amount. As of ~~$464.4~~September 30, 2019, the cumulative adjustment to life and annuity benefits attributable to unrealized gains on the underlying investment portfolio totaled $93.1 million. NaN adjustment was required for the quarter or nine months ended September 30, 2018.

11. Senior Long-Term Debt and Other Debt

In April 2019, the Company entered into a credit agreement for a new revolving credit facility, which provides up to $300 million of capacity for future acquisitions, investments and stock repurchases, and for other working capital and general corporate purposes. At the Company's discretion, up to $200 million of the total capacity may be used for letters of credit. The Company may increase the capacity of the facility by up to $200 million subject to obtaining commitments for the increase and certain other terms and conditions. The Company pays interest on balances outstanding under the facility and a utilization fee for letters of credit issued under the facility. The Company also pays a commitment fee on the unused portion of the facility based on the Company's leverage ratio as calculated under the credit agreement. The credit agreement includes financial covenants that require that the Company not exceed a maximum leverage ratio and maintain a minimum amount of consolidated net worth, as well as other customary covenants and events of default. Markel Corporation, along with Alterra Finance LLC, guaranteed the obligations under the facility. This facility replaced the Company's previous $300 million revolving credit facility and is scheduled to expire in April 2024. There were 0 borrowings outstanding on either credit facility as of September 30, 2019 or December 31, 2018.

In May 2019, the Company issued $600 million of 5.0% unsecured senior notes due May 20, 2049. Net proceeds to the Company were $592.2 million, before expenses. In September 2019, the Company used a portion of these proceeds to retire its 7.125% unsecured senior notes due September 30, 2019 ($234.8 million aggregate principal outstanding at December 31, 2018). The Company expects to use the remainder of the proceeds for general corporate purposes.

In September 2019, the Company issued $300 million of 3.35% unsecured senior notes due September 17, 2029 and $500 million of 4.15% unsecured senior notes due September 17, 2050. Net proceeds to the Company were $297.5 million and $494.5 million, respectively, before expenses. The Company used a portion of these proceeds to purchase $125.2 million of principal on its 6.25% unsecured senior notes due September 30, 2020 and $97.8 million of principal on its 5.35% unsecured senior notes due June 1, 2021 through a tender offer at a total purchase price of $130.1 million and $103.0 million, respectively. In connection with the tender offer and purchase, the Company recognized a loss on early extinguishment of debt of $6.7 million during the quarter and nine months ended September 30, 2019. The Company used a portion of the remaining proceeds to redeem the remaining outstanding balance on its 6.25% and 5.35% unsecured senior notes, as described below, and expects to use the remainder for general corporate purposes.

In October 2019, the Company redeemed the remaining outstanding balance on its 6.25% unsecured senior notes due September 30, 2020 ($224.8 million aggregate principal outstanding at September 30, 2019) and 5.35% unsecured senior notes due June 1, 2021 ($152.2 million aggregate principal outstanding at September 30, 2019) for a total purchase price of $233.4 million and $160.2 million, respectively.

13. Income Taxes

The effective tax rate was 22% and 32% for ~~both~~ the nine months ended September 30, 2019 and 2018, ~~and 2017. During the first quarter of~~respectively. In 2018, the Company decided to ~~make the election~~elect to ~~have~~treat its two ~~of its~~ most significant ~~U.K.~~United Kingdom subsidiaries ~~treated~~ as domestic corporations for U.S. tax purposes. As a result, the earnings and profits of those subsidiaries are no longer considered to be indefinitely reinvested, and during the nine months ended September 30, 2018, the Company recorded a one-time deferred tax charge of $102.0 million ~~provision for deferred U.S. income taxes on~~related to the book and tax basis differences attributable to those ~~subsidiaries, which added~~subsidiaries. This tax charge represented 11% toof the 2018 effective tax rate. ~~The Company continues to be indefinitely reinvested in its other foreign subsidiaries, with the exception of certain Bermuda-based subsidiaries.~~

The Company uses the estimated annual effective tax rate method for calculating its tax provision in interim periods. This method applies the Company's best estimate of the effective tax rate expected for the full year to year-to-date earnings before income taxes. Certain items, including those deemed to be unusual, infrequent or that cannot be reliably estimated (discrete items), such as the deferred tax charge described above, are excluded from the estimated annual effective tax rate and the related tax expense or benefit is reported in the same period as the related item. The Company's estimated annual effective tax rate ~~which excludes the tax attributable to the change in tax status of the two U.K. subsidiaries,~~ was ~~20%~~21% and ~~28%~~20% for the nine months ended September 30, 2019 and 2018, ~~and~~respectively.

The Internal Revenue Service is currently examining the Company’s 2017 ~~respectively. For the nine months ended~~federal income tax return. The Company believes its income tax liabilities were adequate as of September 30, ~~2018 and 2017, the estimated annual effective tax rate differs from the U.S. statutory tax rate of 21% and 35%, respectively, primarily~~2019, however, these liabilities could be adjusted as a result of tax-exempt investment income. The decrease in the estimated annual effective tax rate in 2018 compared to 2017 was primarily attributable to the TCJA, which reduced the U.S. corporate tax rate from 35% to 21%, partially offset by the impact of having higher pre-tax income for the nine months ended September 30, 2018, which reduced the net favorable impact of certain tax adjustments.this examination.

~~12.~~15. Related Party Transactions

The Company engages in certain related party transactions in the normal course of business at arm's length. Details of the Company's transactions with related parties in its insurance-linked securities operations are included below.

Nephila

In November 2018, the Company expanded its insurance-linked securities operations through the acquisition of Nephila, which 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 as both a service company coverholder and agent with binding authority for Lloyd’s Syndicate 2357 (Syndicate 2357) (collectively, the Nephila Reinsurers). Nephila receives management fees for its investment and insurance management services from the Nephila Funds based on the net asset value of the accounts managed, and, for certain funds, incentive fees based on the annual performance of the funds it manages. Nephila also receives commissions from the Nephila Reinsurers, which are based on the direct written premiums of the insurance contracts placed. Total revenues attributed to services provided to the Nephila Funds and the Nephila Reinsurers for the quarter and nine months ended September 30, 2019 were $42.7 million and $124.7 million, respectively.

Within the Company’s program services business, the Company has a program with Nephila through which the Company writes insurance policies that are ceded to Syndicate 2357 and certain other Nephila Reinsurers. Through this arrangement, 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. For the quarter and nine months ended September 30, 2019, gross premiums written through the Company’s program with Nephila were $126.4 million and $360.6 million, respectively, all of which were ceded to Nephila Reinsurers. As of September 30, 2019 and December 31, 2018, reinsurance recoverables on the consolidated balance sheets included $229.8 million and $179.8 million, respectively, due from Nephila Reinsurers.

Under this program, 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 this program exceed the prescribed limit, the Company is obligated to pay such losses to the cedents without recourse to the Nephila Reinsurers. While the Company believes losses under this program 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 both 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.

Markel CATCo

During the first quarter of 2019, the Company entered into various reinsurance contracts with third parties on behalf of Markel CATCo Re, an unconsolidated subsidiary, in exchange for ceding fees. These reinsurance contracts primarily cover losses for events that may occur during 2019, however, in some instances, coverage is also provided for adverse development on 2018 and prior accident years’ loss events. Incurred losses on these contracts are fully ceded to Markel CATCo Re. The loss exposures on these contracts are fully collateralized by Markel CATCo Re up to an amount that the Company believes is unlikely to be exceeded. The Company has credit risk from Markel CATCo Re for any uncollateralized amounts. Markel CATCo Re's ability to pay losses in excess of the collateralized amounts depends on the availability of funds that are not otherwise needed to pay losses on other contracts. As of September 30, 2019, the Company's maximum exposure to loss on these contracts, representing the net uncollateralized risks, was $191.6 million. Total ceding fees attributed to these contracts were $8.8 million, of which $2.2 million and $6.6 million was earned and included in services and other revenues in the Company's consolidated statements of income and other comprehensive income for the quarter and nine months ended September 30, 2019, respectively. Results attributed to these contracts are not included in a reportable segment.

Within the Company's reinsurance operations, the Company also enters into reinsurance contracts that are ceded to Markel CATCo Re. Under this program, the Company retains 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 this program exceed the prescribed limit, the Company is obligated to pay such losses to the cedents without recourse to Markel CATCo Re. Gross premiums written and ceded to Markel CATCo Re were $0.1 million and $5.5 million for the quarter and nine months ended September 30, 2019, respectively, and $1.0 million and $10.6 million for the quarter and nine months ended September 30, 2018, respectively.

See note 14 for details of the Company's other transactions with Markel CATCo Re and the Markel CATCo Funds.

Effective January 1, 2018, the Company adopted ASU No. 2016-01 and as a result, equity securities are no longer classified as available-for-sale with unrealized gains and losses recognized in other comprehensive income. Rather, changes in the fair value of equity securities are now recognized in net income. Upon adoption of this ASU, cumulative net unrealized gains on equity securities of $2.6 billion, net of deferred income taxes, were reclassified from accumulated other comprehensive income into retained earnings.

Effective January 1, 2018, the Company adopted ASU No. 2018-02, which provided an option to reclassify tax effects remaining in accumulated other comprehensive income as a result of the Tax Cuts and Jobs Act to retained earnings. As a result of adopting the ASU, the Company reclassified $401.5 million of previously recognized deferred taxes from accumulated other comprehensive income into retained earnings as of January 1, 2018.

Effective January 1, 2018, the Company adopted ASU No. 2016-01 and equity securities are no longer classified as available-for-sale with unrealized gains and losses recognized in other comprehensive income, rather, changes in the fair value of equity securities are now recognized in net income.

~~14. Contingencies~~

~~Aspen Holdings.~~ ~~In October 2010,~~18. 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 ~~its acquisition~~in April 2019 and found no evidence that MCIM personnel acted in bad faith in exercising business judgment in the setting of ~~Aspen Holdings, Inc. (Aspen)~~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 Markel CATCo Inquiries are ongoing. The Company cannot currently predict the duration, scope or result of the Markel CATCo Inquiries.

During the internal review, the Company discovered violations of Markel policies by two senior executives of MCIM. As a result, these two executives are no longer with the Company (the MCIM Executive Departures).

Between January 11, 2019 and March 7, 2019, several related putative class actions were filed in the U.S. District Court for the Southern District of New York against Markel Corporation and certain present or former officers and directors alleging violations of the federal securities laws relating to the matters that are the subject of the Markel CATCo Inquiries (the Markel Securities Litigation). The actions were consolidated. On August 6, 2019, the Markel Securities Litigation was voluntarily dismissed.

On February 21, 2019, Anthony Belisle and Alissa Fredricks, two senior executives who are no longer with MCIM, each separately filed suit against MCIM and Markel Corporation, which suits were amended on March 29, 2019 and March 28, 2019, respectively (the MCIM Executive Suits). As ~~part of the consideration~~amended, Mr. Belisle's complaint alleged claims for, that acquisition, Aspen shareholders received contingent value rights (CVRs). Based on a valuation of the CVRs as of their December 31, 2017 maturity date, we paid $9.9 million to the CVR holders on June 5, 2018, which represents 90% of the undisputed portion of the final amount the Company believes it is required to pay under the CVR agreement.

Prior to the December 31, 2017 maturity date, the CVR holder representative, Thomas Yeransian, had disputed the Company's estimation of the value of the CVRs. On September 15, 2016, Mr. Yeransian filed a suit alleging, among other things, ~~that the Company is in default under the CVR agreement. The holder representative seeks: $47.3~~breach of contract, defamation, invasion of privacy, indemnification, intentional interference with contractual relations and deceptive and unfair acts and sought relief of, among other things, $66.0 million in incentive compensation, enhanced compensatory damages, ~~which represents~~consequential damages, damages for emotional distress and injury to reputation, exemplary damages and attorneys' fees. In June 2019, MCIM, Markel Corporation, and Mr. Belisle agreed to commence binding arbitration to finally, fully and confidentially resolve the ~~unadjusted value of~~claims and counterclaims alleged in the ~~CVRs; plus interest ($13.4 million through September 30, 2018)~~action, and ~~default interest (up to an additional $11.5 million through September 30, 2018, depending on~~ the ~~date any default occurred);~~Belisle suit was dismissed with prejudice in July 2019. The arbitrators have been selected and ~~an unspecified amount of punitive damages, costs, and attorneys’ fees.~~

~~Management~~the arbitration proceeding has commenced. The Company believes ~~the holder representative’s suit to be~~that Mr. Belisle's claims are without merit and ~~will vigorously defend against it. Further, management believes that~~ any material loss resulting from the ~~holder representative’s suit~~Belisle binding arbitration to be remote. As amended, Ms. Fredricks' complaint alleged claims for, among other things, breach of contract, defamation, invasion of privacy, indemnification, intentional interference with contractual relations and deceptive and unfair acts and sought relief of, among other things, $7.5 million in incentive compensation, consequential damages, damages for emotional distress and injury to reputation, exemplary damages and attorneys' fees. In June 2019, the action filed by Ms. Fredricks was settled by mutual agreement to the satisfaction of all parties.

The Markel CATCo Inquiries, Markel Securities Litigation, MCIM Executive Departures and MCIM Executive Suits, as well as other related 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 Company's internal review, including legal and investigation costs, as well as legal costs incurred in connection with any existing or future litigation, 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.

In December 2018, investors in the Markel ~~Ventures.~~CATCo Funds were offered an additional redemption opportunity (the Special Redemption). Under the Special Redemption, investors in the Markel CATCo Funds were offered the option, through March 29, 2019, to redeem any or all shares held as of June 30, 2019. Through both the Special Redemption and the annual redemption for January 1, 2019, substantially all of the capital in the Markel CATCo Funds was tendered for redemption. In July 2019, MCIM announced it would cease accepting new investments in the Markel CATCo Funds and would not write any new business in Markel CATCo Re. Both the Markel CATCo Funds and Markel CATCo Re have been placed into run-off, returning capital to investors as it becomes available. The process is expected to take approximately three years. Payment for the redemptions of shares is an obligation of the Markel CATCo Funds, not Markel Corporation or its subsidiaries.

b) The Company has ~~been reviewing~~reviewed events at one of its Markel Ventures products businesses. Since becoming aware of a matter late in the first quarter of 2018 related to the business's manufacture of products, the Company has conducted an investigation, ~~reviewing~~reviewed the business's operations and ~~developing~~developed remediation plans. Upon completion of its review during ~~the second quarter of~~ 2018, the Company ~~recorded~~accrued an expense of $33.5 million in its results of operations. This amount represented management’s best estimate of amounts ~~currently~~ considered probable including: remediation costs associated with the manufacture of products, costs associated with the investigation of this matter, a write down of inventory on hand and settlement costs related to pre-existing litigation. ~~The Company also recorded an impairment charge of $14.9 million during the second quarter of 2018 which reduced the carrying value of intangible assets at this reporting unit to zero.~~

Final resolution of this matter could ultimately result in additional remediation and other costs, the amount of which cannot be estimated at this time, but which could have a material impact on the Company’s income before income taxes. However, management does not expect this matter ultimately will have a material adverse effect on the Company’s results of operations or financial condition. If a determination is made that additional costs associated with this matter are considered probable, these additional costs will be recognized as an expense in the Company's results of operations. As of September 30, 2019, $21.4 million remained accrued for ongoing remediation efforts.

In addition, 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.

c) In September 2019, the Company announced the launch of Lodgepine Capital Management Limited (Lodgepine), its new retrocessional insurance-linked securities fund manager in Bermuda. Lodgepine's initial product offering will be Lodgepine Fund Limited, a property catastrophe retrocessional investment fund, which is expected to launch by January 1, 2020. The Company has committed to invest up to $100 million in Lodgepine Fund Limited.

~~15.~~19. Subsequent Events

In ~~early~~ October ~~2018, the Gulf Coast and southeastern regions of the United States~~2019, Japan sustained losses from ~~Hurricane Michael.~~Typhoon Hagibis. Based on information currently available, the Company estimates its range of net incurred losses and loss adjustment expenses on this event is between $60 million and $120 million before income taxes. This estimated range of losses was derived based on ~~initial~~preliminary industry loss estimates ~~policy level~~and reviews ~~and direct contact with insureds and brokers when possible.~~of in-force contracts. However, ~~the Company is still gathering preliminary~~early industry loss ~~data and few losses~~estimates for Typhoon Hagibis have ~~been reported at this time. Potential losses associated with business interruption are also not yet clear.~~a wide range of variability. The Company ~~continues to closely monitor reported claims and~~ will refine its ~~initial~~ estimate of losses, which will be recorded in the fourth quarter of ~~2018,~~2019, as more details about the actual level of claims ~~becomes more certain.~~emerge.

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 ~~U.S.~~United States (U.S.) generally accepted accounting principles ~~(U.S. GAAP)~~(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).

Our Business

We are a diverse financial holding company serving a variety of niche markets. Our principal business markets and underwrites specialty insurance products. 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. We also own interests in various 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.

Our business is comprised of the following types of operations:

Underwriting - our underwriting operations are comprised of our risk-bearing insurance and reinsurance operations ~~which include the run-off of underwriting operations that were discontinued in conjunction with acquisitions~~

Investing - our investing activities are primarily related to our underwriting operations

Markel Ventures - our Markel Ventures operations include our controlling interests in a diverse portfolio of businesses that operate ~~in various industries~~outside of the specialty insurance marketplace

Insurance-linked securities - our insurance-linked securities operations include investment fund managers that offer a variety of investment products, including insurance-linked securities, catastrophe bonds, insurance swaps and weather derivatives

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

~~Markel CATCo - our Markel CATCo operations include an investment fund manager that offers insurance-linked securities to investors~~

Underwriting and Investing

In conjunction with the continued growth and diversification of our business, beginning the first quarter of 2018 we changed the way we review our ongoing underwriting operations. Effective January 1, 2018, our

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. Results for lines of business discontinued prior to, or in conjunction with, acquisitions, including development on asbestos and environmental loss reserves and the results attributable to the run-off of life and annuity reinsurance business, are monitored separately and are not included in a reportable segment. All investing activities related to our underwriting operations are included in the Investing segment.

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 as well as our syndicate at Lloyd's of London (Lloyd's).~~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 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, including catastrophe-exposed property, personal property, workers' compensation, marine and energy liability coverages, specialty program insurance for well-defined niche markets, and liability and other coverages tailored for unique exposures. Business in this segment is written through our Markel Assurance, Markel Specialty and Markel International divisions. The Markel Assurance division writes commercial ~~risks,~~and Fortune 1000 accounts on an excess and surplus lines ~~basis~~ as well as admitted ~~and non-admitted basis, using a network of brokers managed on a regional~~ basis. The Markel Specialty division writes program insurance and other specialty coverages for well-defined niche markets, primarily on an admitted basis. The Markel International division writes business worldwide, primarily from our London-based platform, which includes our syndicate at Lloyd's.

In November 2017, we completed the acquisition of State National Companies, Inc. (State National), a leading specialty provider of property and casualty insurance. The acquisition of State National adds a premier fronting platform to our insurance operations through which insurance products can be offered throughout the United States. State National also offers collateral protection insurance (CPI) to credit unions and regional banks. Results attributable to CPI business are included in the Insurance segment. Results attributable to the fee-based program services (fronting) operations are reported within our other operations, which are not included in a reportable segment.

In April 2017, we completed the acquisition of SureTec Financial Corp. (SureTec), a Texas-based privately held surety company primarily offering contract, commercial and court bonds. Results attributable to SureTec are included in the Insurance segment.

Our Reinsurance segment includes property, casualty and specialty 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: property, ~~(including~~including catastrophe-exposed ~~property),~~property, professional liability, general casualty, credit, surety, auto, and workers' compensation. Our reinsurance product offerings are underwritten ~~primarily~~principally by our Global Reinsurance division.

Markel Ventures

Through our wholly-owned subsidiary Markel Ventures, Inc. (Markel Ventures), we own interests in various businesses that ~~effective January 1, 2018,~~ we monitor and report in the Markel Ventures segment. These businesses are viewed by management as separate and distinct from our insurance operations and are comprised of a diverse portfolio of businesses from different industries that offer various types of products and services to businesses and consumers, predominately in the United States. Our products group manufactures, builds or produces consumer and industrial products, such as equipment used in baking systems and food processing, portable dredges, over-the-road car haulers and equipment, laminated oak and composite wood flooring used in the trucking industry, ~~dorm~~dormitory furniture, wall systems, medical casework and marine panels, storage and transportation equipment for specialty gas, ornamental plants, fashion handbags and residential homes. The services group offers consumer and business services, such as management and technology consulting, leasing and management of manufactured housing communities, behavioral healthcare, concierge health programs and retail ~~intelligence and management and technology consulting.~~intelligence.

In ~~August 2017,~~October 2018, we acquired ~~81%~~90% of ~~Costa Farms,~~Brahmin Leather Works (Brahmin), a ~~Florida-based~~Massachusetts-based privately held ~~grower~~creator of ~~house and garden plants.~~fashion leather handbags. Results attributable to ~~Costa Farms~~Brahmin are included ~~with~~in our Markel Ventures segment.

Insurance-linked Securities

Our ~~other~~insurance-linked securities operations are comprised of our Nephila and Markel CATCo operations.

In November 2018, we completed the acquisition of all of the outstanding shares of Nephila Holdings Ltd. (together with its subsidiaries, Nephila). Through its subsidiaries, Nephila primarily serves as an insurance and investment fund manager headquartered in Bermuda 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 also ~~include~~provides managing general agent services and acts as an insurance manager to certain Bermuda Class 3 and 3A reinsurance companies and as both a service company coverholder and agent with binding authority for Lloyd’s Syndicate 2357 (Syndicate 2357) (collectively, the 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. Nephila's net assets under management were $10.5 billion and $11.6 billion as of September 30, 2019 and December 31, 2018, respectively.

Our Markel CATCo operations ~~which~~ are conducted through Markel CATCo Investment Management Ltd. (MCIM). MCIM is an insurance-linked securities investment fund manager ~~and reinsurance manager~~ headquartered in Bermuda that focused on building and managing highly diversified, collateralized retrocession and reinsurance portfolios covering global property catastrophe risks. 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). MCIM also serves as the investment manager to CATCo Reinsurance Opportunities Fund Ltd. (CROF), a limited liability closed-end Bermuda exempted mutual fund company listed on a market operated by the London Stock Exchange and on the Bermuda Stock Exchange. CROF invests substantially all of its assets in Markel CATCo Reinsurance Fund Ltd. Both Markel CATCo Re and the Markel CATCo Funds are unconsolidated subsidiaries of Markel Corporation. MCIM's net assets under management were $3.0 billion and $3.4 billion as of September 30, 2019 and December 31, 2018, respectively. In July 2019, MCIM announced it would cease accepting new investments in the Markel CATCo Funds and would not write any new business in Markel CATCo Re. Both the Markel CATCo Funds and Markel CATCo Re have been placed into run-off, returning capital to investors as it becomes available. See note 18 of the notes to consolidated financial statements for further details regarding recent developments within our Markel CATCo operations.

In September 2019, we announced the launch of Lodgepine Capital Management Limited (Lodgepine), our new retrocessional insurance-linked securities fund manager in Bermuda. Lodgepine's initial product offering will be Lodgepine Fund Limited, a property catastrophe retrocessional investment fund, which is expected to launch by January 1, 2020. We have committed to invest up to $100 million in Lodgepine Fund Limited.

Program Services

Our program services business is conducted through our State National division and is separately managed from our underwriting operations. Our program services business generates fee income, in the form of ceding (program service) fees, by offering issuing carrier capacity to both specialty 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. 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, substantially all of which is ceded to third parties. Gross written premiums in our program services business were $619.2 million and $1.8 billion for the quarter and nine months ended September 30, 2019, respectively, and $561.3 million and $1.6 billion for the quarter and nine months ended September 30, 2018, respectively, substantially all of which was ceded.

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, including litigation contingencies. These estimates, by necessity, are based on assumptions about numerous factors.

~~We review the following~~Our critical accounting estimates consist of estimates and assumptions ~~quarterly: evaluating~~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 the reinsurance allowance for doubtful accounts and income tax liabilities, as well as analyzing the recoverability of deferred tax assets, estimating reinsurance premiums written and earned and evaluating the investment portfolio for other-than-temporary declines in estimated fair value. Critical accounting estimatesquarterly. Estimates and assumptions ~~for~~used in the valuation of goodwill and intangible assets are reviewed in conjunction with an acquisition and goodwill and indefinite-lived intangible assets are reassessed at least annually for impairment. Actual results may differ materially from the estimates and assumptions used in preparing the consolidated financial statements.

Readers are urged to review our ~~2017~~2018 Annual Report on Form 10-K for a more complete description of our critical accounting estimates.

~~Recent Changes to Significant Accounting Policies~~

Effective January 1, 2018, as a result of recent significant changes in economic facts and circumstances, management reassessed its functional currency determination as required by Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 830, ~~Foreign Currency Matters~~. As a result of the reassessment, the U.S. Dollar is the only functional currency for most of our foreign underwriting operations. Consequently, more foreign currency denominated transactions are designated as non-functional, with related remeasurement gains and losses included in net foreign exchange gains (losses) within net income. However, available-for-sale securities denominated in non-functional currencies are recorded at fair value with resulting gains and losses, including the portion attributable to movements in exchange rates, included in the change in net unrealized gains on available-for-sale investments, net of taxes, within other comprehensive income. As a result, while we attempt to naturally hedge our exposure to foreign currency fluctuations by matching assets and liabilities in currency, there is a financial statement mismatch between the gains or losses recorded in net income related to insurance reserves denominated in non-functional currencies and the gains or losses recorded in other comprehensive income related to the available-for-sale securities supporting the reserves. The change in our functional currency determination has been applied on a prospective basis in accordance with ASC 830. Therefore, any translation gains and losses that were previously recorded in accumulated other comprehensive income remain unchanged through December 31, 2017. See note 1 of the notes to consolidated financial statements for further details. The quarter ended September 30, 2018 included a pre-tax foreign exchange gain of $1.4 million ($1.1 million, net of taxes) compared to a pre-tax foreign exchange gain of $1.8 million for the quarter ended September 30, 2017. The nine months ended September 30, 2018 included a pre-tax foreign exchange gain of $65.4 million ($51.6 million, net of taxes) compared to a pre-tax foreign exchange gain of $2.7 million for the nine months ended September 30, 2017.

Recent Accounting Pronouncements

The ~~FASB~~following Accounting Standard Updates (ASUs) issued ~~several accounting standards updates (ASUs) that became effective January 1, 2018.~~

~~The adoption of ASU No. 2014-09,~~ ~~Revenue from Contracts with Customers (Topic 606)~~ ~~and several other ASUs that were issued as amendments to ASU No. 2014-09 did not have a material impact on our consolidated financial position, results of operations or cash flows.~~

~~As a result of adopting ASU No. 2016-01,~~ by the Financial ~~Instruments (Topic 825): Recognition and Measurement of Financial Assets and Financial Liabilities,~~ changes in the fair value of equity securities are now recognized in net income rather than other comprehensive income. With this accounting change, we expect more volatility in net income. However, this accounting change does not impact total comprehensive income. On January 1, 2018, cumulative net unrealized gains on equity securities of $2.6 billion, net of deferred income taxes of $684.4 million, were reclassified from accumulated other comprehensive income into retained earnings.

~~As a result of early adopting ASU No. 2018-02,~~ ~~Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income~~, we elected to reclassify tax effects remaining in accumulated other comprehensive income as a result of the Tax Cuts and Jobs Act (TCJA) to retained earnings. Upon enactment of the TCJA, the U.S. corporate tax rate was reduced from 35% to 21% and our U.S. deferred tax balances were remeasured to the lower enacted U.S. corporate tax rate. U.S. GAAP requires the effects of changes in tax rates and laws on deferred tax balances to be recorded as a component of income tax expense in the period of enactment, even if the assets and liabilities relate to items of accumulated other comprehensive income. As a result of adopting the ASU, on January 1, 2018, previously recognized deferred taxes of $401.5 million were reclassified from accumulated other comprehensive income into retained earnings.

~~Other ASUs that we expect~~Accounting Standards Board have the most potential to significantly impact our consolidated financial position, results of operations or cash flows in future periods upon ~~adoption and are currently evaluating are as follows:~~adoption:


•	ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments


•	ASU No. 2018-12, Financial Services—Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts


•	ASU No. 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract

~~Key Performance Indicators~~

An important measure of our financial success is our ability to grow book value per share at a high rate of return over a long period of time. To mitigate the effects of short-term volatility, we measure ourselves over a five-year period. We believe that growth in book value per share is a comprehensive measure of our success because it includes all underwriting, investing and operating results. We measure underwriting results by our underwriting profit or loss and combined ratio. We measure investing results by our net investment income and net investment gains as well as our taxable equivalent total investment return. We measure Markel Ventures' results, by its operating income and net income, as well as earnings before interest, income taxes, depreciation and amortization (EBITDA). These measures are discussed in greater detail under "Results of Operations."

As we have continued to expand and diversify our operations beyond underwriting and investing, we recognize that book value per share does not capture all of the economic value in our business, as a growing portion of our operations are not recorded at fair value or otherwise captured in book value. As a result, we also measure our financial success through the growth in the market price of a share of our stock, or total shareholder return. For the nine months ended September 30, 2018, our share price increased 4%.

Underwriting Results

Underwriting profits are a key component of our strategy to ~~grow book value per share.~~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 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. A combined ratio less than 100% indicates an underwriting profit, while a combined ratio greater than 100% reflects an underwriting loss. 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.

Underwriting results for the quarter and nine months ended September 30, 2019 included $42.6 million of underwriting loss from Hurricane Dorian and Typhoon Faxai (2019 Catastrophes). Estimated net losses and loss adjustment expenses on the 2019 Catastrophes were net of estimated ceded losses of $4.8 million. Both the gross and net loss estimates on the 2019 Catastrophes represent our best estimate of losses based upon information currently available. Our estimate for these losses is based on preliminary industry loss estimates, output from both industry and proprietary models as well as a review of in-force contracts, and for Hurricane Dorian, claims received to date and detailed policy level reviews. Early industry loss estimates for Typhoon Faxai have a wide range of variability. While we believe our reserves for the 2019 Catastrophes as of September 30, 2019 are adequate, we continue to closely monitor industry loss estimates and reported claims and will adjust our estimates of gross and net losses as new information becomes available.

Underwriting results for the quarter and nine months ended September 30, 2018 included $75.7 million of underwriting loss from Hurricane Florence and Typhoon Jebi (2018 Catastrophes). The underwriting loss on the 2018 Catastrophes was comprised of $77.8 million of estimated net losses partially offset by $2.1 million of net assumed reinstatement premiums, or six points and two points on the combined ratio for the quarter and nine months ended September 30, 2018, respectively. The estimatedEstimated net losses and loss adjustment expenses on the 2018 Catastrophes were net of estimated ceded losses of $28.6 million. Both the gross and net loss estimates on the 2018 Catastrophes represent our best estimate of losses based upon information currently available. Our estimate for these losses is based on claims received to date and detailed policy level reviews, industry loss estimates, output from both industry and proprietary models as well as a review of in-force contracts.

Underwriting results for the quarter and nine months ended September 30, 2017 included $503.0 million of underwriting loss from Hurricanes Harvey, Irma and Maria as well as the earthquakes in Mexico (2017 Catastrophes). The underwriting loss on the 2017 Catastrophes was comprised of $521.2 million of estimated net losses partially offset by $18.2 million of net assumed reinstatement premiums, or 46 points and 16 points on the combined ratio for the quarter and nine months ended September 30, 2017, respectively.

The following table summarizes, by segment, the components of the underwriting losses related to the ~~2018~~2019 and ~~2017~~2018 Catastrophes for the quarter and nine months ended September 30, 2019 and 2018, ~~and 2017,~~ respectively.

The decrease in the consolidated combined ratio for the quarter ~~and nine months~~ ended September 30, ~~2018~~2019 was primarily attributable to lower catastrophe losses and more favorable development on prior accident years' loss reserves within our Insurance segment in ~~2018~~2019 compared to ~~2017.~~2018. The ~~decrease~~increase in the consolidated combined ratio for the ~~quarter~~nine months ended September 30, 2019 was ~~partially offset~~driven primarily by less favorable development on prior accident years' loss reserves in 2019 compared to 2018 within ~~both of~~ our ~~underwriting segments and a higher expense ratio in our Reinsurance~~Insurance segment.

Insurance Segment

The combined ratio for the Insurance segment was 92% (including one point for the underwriting loss on the 2019 Catastrophes) for the quarter ended September 30, 2019 compared to 96% (including four points for the underwriting loss on the 2018 Catastrophes) and 92% (including one point for the underwriting loss on the 2018 Catastrophes) for the quarter and nine months ended September 30, 2018, respectively, compared to 119% (including 31 points for the underwriting loss on the 2017 Catastrophes) and 101% (including 11 points for the underwriting loss on the 2017 Catastrophes) for the same ~~periods~~period of ~~2017.~~2018.

For the quarter ended September 30, ~~2018,~~2019, the decrease in the combined ratio was driven by lower catastrophe losses in the third quarter of ~~2018~~2019 compared to ~~2017~~2018 and ~~a decrease in the expense ratio, partially offset by less~~more favorable development on prior accident years' loss reserves. Higher earned premiums in 2019 compared to 2018 had a favorable impact on our expense ratio and an unfavorable impact on the prior years' loss ratio.

The Insurance segment's combined ratio for the quarter ended September 30, ~~2018~~2019 included ~~$111.1~~$135.0 million of favorable development on prior ~~accident~~ years' loss reserves compared to ~~$128.4~~$111.1 million for the same period ~~in 2017. Additionally, the benefit~~ of 2018.

The ~~decrease~~increase in favorable development was primarily due to ~~less~~more favorable development on our professional liability and ~~property~~general liability product lines in 2019 compared to 2018, partially offset by ~~more~~less favorable development on our ~~workers' compensation and~~ marine and energy product ~~lines.~~lines in 2019 compared to 2018. For the quarter ended September 30, ~~2018,~~2019, favorable development was most significant on our general liability ~~and marine and energy~~ product lines, ~~across several~~primarily on the 2014 to 2018 accident years, ~~and on our~~ workers' compensation product lines, primarily on the ~~2015~~2016 to 2018 accident years, and professional liability product lines, primarily on the 2017 and 2018 accident years. The favorable development on prior years' loss reserves in the third quarter of ~~2017~~2018 was most significant on our general liability, workers' compensation and marine and energy product lines.

The expense ratio for the quarter ended September 30, 2019 was flat compared to the same period of the prior year. The favorable impact from higher earned premiums in 2019 compared to 2018 was offset by a lower benefit from ceding commissions in 2019 compared to 2018 due to recent changes in our outwards reinsurance treaty structures. In late 2018, we shifted from buying proportional reinsurance coverages towards excess of loss coverages for our general liability and professional liability product lines.

The combined ratio for the Insurance segment was 94% for the nine months ended September 30, 2019 compared to 92% (including one point for the underwriting loss on the 2018 Catastrophes) for the same period of 2018.

For the nine months ended September 30, 2019, the increase in the combined ratio was driven by less favorable development on prior accident years' loss reserves, partially offset by lower catastrophe losses in 2019 compared to 2018. Higher earned premiums in 2019 compared to 2018 had a favorable impact on our expense ratio and an unfavorable impact on the prior years' loss ratio.

The current accident year loss ratio for the nine months ended September 30, 2019 decreased compared to the prior period, primarily due to lower catastrophe losses in 2019 compared to 2018.

The Insurance segment's combined ratio for the nine months ended September 30, 2019 included $309.3 million of favorable development on prior years' loss reserves compared to $369.8 million for the same period in 2018. The decrease in favorable development was primarily due to less favorable development on our marine and energy and programs products lines in 2019 compared to 2018 and adverse development on our property product lines in 2019 compared to favorable development in 2018. These unfavorable changes were partially offset by more favorable development on our general liability product lines. The adverse development on our property product lines in 2019 was due to adverse development on our brokerage property product line resulting from higher than expected losses, primarily on the 2018 accident year, as well as modest adverse development on prior year catastrophes. Additionally, the benefit of favorable development on the combined ratio was reduced in 2019 as a result of higher earned premiums in 2019 compared to 2018. For the nine months ended September 30, 2019, favorable development was most significant on our general liability product lines, primarily on the 2013 to 2017 accident years, workers' compensation product lines, primarily on the 2015 to 2018 accident years, and professional liability product lines, primarily on the 2017 and 2018 accident years. The favorable development on prior years' loss reserves in 2018 was most significant on our general liability, workers' compensation, marine and energy and professional liability product lines.


•	The expense ratio for the nine months ended September 30, 2019 decreased compared to the same period of 2018, primarily due to the favorable impact of higher earned premiums, partially offset by a lower benefit from ceding commissions due to changes in our outwards reinsurance treaty structures, as described above.

Reinsurance Segment

The combined ratio for the Reinsurance segment was 103% (including 12 points for the underwriting loss on the 2019 Catastrophes) for the quarter ended September 30, 2019 compared to 115% (including 16 points for the underwriting loss on the 2018 Catastrophes) for the same period of 2018.

For the quarter ended September 30, 2019, the decrease in the combined ratio was driven by a lower current accident year loss ratio and a lower expense ratio in 2019 compared to 2018.

The current accident year loss ratio for the quarter ended September 30, 2019 decreased compared to the same period in 2018. The decrease in the current year loss ratio was attributable to the beneficial impact of more favorable premium adjustments in 2019 compared to 2018, primarily on our workers' compensation and credit and surety product lines, partially offset by an unfavorable impact arising from changes in our outwards property reinsurance treaty structures in 2019 related to the elimination of our proportional property reinsurance treaty and the purchase of additional excess of loss property and catastrophe reinsurance coverage. The decrease in the current accident year loss ratio was also attributable to lower catastrophe losses in 2019 compared to 2018.

The Reinsurance segment's combined ratio for the quarter ended September 30, 2019 included $13.8 million of favorable development on prior accident years' loss reserves compared to $12.7 million for the same period of 2018. For the quarter ended September 30, 2019, favorable development was most significant on our property product lines across several accident years. The favorable development on prior years' loss reserves in the third quarter of 2018 was most significant on our credit and surety, marine and energy and workers' compensation product lines.

The expense ratio for the quarter ended September 30, 2019 decreased compared to the ~~prior year,~~same period of 2018 primarily due tolower general expenses, the favorable impact of higher earned premiums and lower profit sharing expenses in ~~the third quarter of 2018~~2019 compared to 2018.

The combined ratio for the Reinsurance segment was 99% (including four points for the underwriting loss on the 2019 Catastrophes) for the nine months ended September 30, 2019 compared to 100% (including five points for the underwriting loss on the 2018 Catastrophes) for the same period of ~~2017 and higher acquisition-related expenses in 2017 compared to~~ 2018. ~~These favorable impacts were partially offset by higher profit sharing in the third quarter of 2018 compared to 2017.~~

For the nine months ended September 30, ~~2018,~~2019, the decrease in the combined ratio was driven by lower catastrophe losses, ~~and lower attritional losses in 2018 compared to 2017,~~ partially offset by a ~~less favorable prior accident years' loss ratio.~~higher expense ratio in 2019 compared to 2018.

Excluding the impact of ~~the~~2019 and 2018 ~~and 2017~~ Catastrophes, the current accident year loss ratio for the nine months ended September 30, 2018 decreased compared to the prior year period primarily due to lower attritional losses across most product lines, partially offset by higher attritional losses on our marine and energy product lines.

The Insurance segment's combined ratio for the nine months ended September 30, 2018 included $369.8 million of favorable development on prior accident years' loss reserves compared to $353.8 million for the same period in 2017. Despite more favorable development on prior years' loss reserves in 2018, the benefit to our prior years' loss ratio was reduced given the impact of higher earned premiums. The increase in favorable development was primarily due to more favorable development on our workers' compensation and marine and energy product lines, partially offset by less favorable development on our professional liability and property product lines in 2018 compared to 2017. The increase in favorable development on the marine and energy product lines was largely attributable to favorable development in 2018 related to the 2017 Catastrophes. For the nine months ended September 30, 2018, favorable development was most significant on our general liability and workers compensation product lines across several accident years, marine and energy product lines, primarily on the 2015 to 2017 accident years and on our professional liability product lines, primarily on the 2016 and 2017 accident years. The favorable development on prior years' loss reserves in 2017 was most significant on our general liability, professional liability, workers' compensation and marine and energy product lines.

~~The expense ratio~~2019 was flat compared to the prior year. Changes in our outwards property reinsurance treaty structures in 2019 as described above resulted in a higher net attritional loss ratio. The ~~favorable~~ impact ~~from higher earned premiums~~of these changes was offset by ~~an unfavorable~~the favorable impact ~~from our new surety business, which carries a higher expense ratio than other products~~of reinstatement premiums and more favorable premium adjustments in ~~the segment, and higher acquisition-related expenses in 2018~~2019 compared to ~~2017.~~

~~Reinsurance Segment~~

~~The combined ratio for the Reinsurance segment was 115% (including 16 points for the underwriting loss on the~~ 2018, Catastrophes) and 100% (including five points for the underwriting loss on the 2018 Catastrophes) for the quarter and nine months ended September 30, 2018, respectively, compared to 183% (including 95 points for the underwriting loss on the 2017 Catastrophes) and 135% (including 34 points for the underwriting loss on the 2017 Catastrophes) for the same periods of 2017.

For the quarter ended September 30, 2018 the decrease in the combined ratio was driven by lower catastrophe losses in 2018 compared to 2017, partially offset by a higher expense ratio, higher attritional losses and less favorable development on prior years' loss reserves in 2018 compared to 2017.

Excluding the impact of the 2018 and 2017 Catastrophes, the current accident year loss ratio for the quarter ended September 30, 2018 increased compared to the same period of 2017 due to higher attritional losses, primarily ~~on our whole account product line.~~

The Reinsurance segment's combined ratio for the quarter ended September 30, 2018 included $12.7 million of favorable development on prior accident years' loss reserves compared to $21.2 million of favorable development in 2017. The decrease in favorable development was primarily due to less favorable development on our property product lines and more adverse development on our general liability product lines, partially offset by more favorable development on our workers' compensation product lines in the third quarter of 2018 compared to the same period of 2017. We also experienced favorable development on our surety product lines in the third quarter of 2018 compared to slightly adverse development in the same period of 2017. Favorable development in 2018 was most significant on our surety product lines, primarily on the 2016 and 2017 accident years, marine and energy product lines, primarily on the 2013 and 2014 accident years and workers' compensation product lines, primarily on the 2013 and 2017 accident years. Favorable development on prior years' loss reserves in 2017 was most significant on our propertyprofessional liability product lines.

The expense ratio increased for the quarter ended September 30, 2018 compared to the same period of 2017, primarily due to the impact of lower assumed reinstatement premiums related to catastrophes, resulting in lower earned premiums, in the third quarter of 2018 compared to the third quarter of 2017.

For the nine months ended September 30, 2018 the decrease in the combined ratio was driven by lower catastrophe losses in 2018 compared to 2017 and favorable development on prior accident years' loss reserves, partially offset by a higher expense ratio.

The Reinsurance segment's combined ratio for the nine months ended September 30, ~~2018~~2019 included ~~$18.1~~$20.7 million of favorable development on prior accident years' loss reserves compared to ~~$22.2~~$18.1 million ~~of adverse~~for the same period in 2018. In both periods, the favorable development ~~in 2017. In 2018,~~on prior years' loss reserves ~~included $18.4 million of~~was partially offset by adverse development ~~or three points~~on prior year catastrophes. For the nine months ended September 30, 2019, favorable development was most significant on our aviation and whole account product lines across several accident years and on our auto product lines, primarily on the ~~Reinsurance segment combined ratio, related~~2012 to ~~the 2017 Catastrophes. In 2017,~~2015 accident years. The favorable development on prior years' loss reserves included $85.0 million of adverse development, or 12 points on the Reinsurance segment combined ratio, related to the decrease in the discount rate, known as the Ogden Rate, used to calculate lump sum awards in United Kingdom (U.K.) bodily injury cases. We also experienced less favorable development on our whole account product lines in 2018 compared to 2017, adverse development on our property product lines in 2018 compared to favorable development on these lines in 2017 and more adverse development on our general liability product lines in 2018. This unfavorable activity was partially offset by favorable development on our surety product lines in 2018 compared to adverse development in 2017. Favorable development in 2018 was most significant on our credit and surety and marine and energy product ~~lines across several accident years. Favorable development on prior years' loss reserves in 2017 was most significant on our whole account product line and on our property product~~ lines.

Gross premium volume in our underwriting operations for the quarter and nine months ended September 30, ~~2018~~2019 increased ~~12%~~11% and 9%10%, respectively, compared to the same periods of ~~2017.~~2018. The increase in gross premium volume for the ~~both the~~ quarter ~~and nine months~~ ended September 30, ~~2018~~2019 was attributable to an increase in gross premium volume within our Insurance segment. The increase in gross premium volume for the nine months ended September 30, 2019 was attributable to an increase in gross premium volume within both our Insurance and Reinsurance segments. Also impacting consolidated gross premium volume were gross premiums written from our program services business and other fronting arrangements, which increased 10% and 16% for the quarter and nine months ended September 30, ~~2018 was $561.3 million and $1.6 billion, respectively, of~~2019, respectively.

Substantially all gross premiums written in our program services business~~and other fronting arrangements were ceded to third parties for ~~both~~ the quarter and nine months ended September 30, 2019 and 2018.

Gross premium volume in our Insurance segment increased 14% and ~~15%~~11% for the quarter and nine months ended September 30, ~~2018,~~2019, respectively. The increase in gross premium volume for ~~the~~ both the quarter and nine months ended September 30, ~~2018~~2019 was primarily driven by growth within our ~~general~~professional liability, ~~professional~~general liability and personal lines product ~~lines, as well as increased premiums from our new surety and collateral protection businesses which were acquired in 2017.~~lines.

The ~~increase~~decrease in gross premium volume for the quarter ended September 30, ~~2018~~2019 was driven by certain contracts that were not renewed and lower gross premiums on multi-year contracts, primarily in our property product lines.

Significant variability in gross premium volume can be expected in our Reinsurance segment due to individually significant contracts and multi-year contracts.

When we believe the prevailing market price will not support our underwriting profit targets, the business is not written.

The ~~decrease~~increase in net retention for the quarter and nine months ended September 30, ~~2018~~2019 compared to the same periods of ~~2017~~2018 was ~~primarily~~ driven by an increase in net retention within the Insurance segment resulting from recent changes in our outwards reinsurance treaty structures. In late 2018, we shifted from buying proportional reinsurance coverages towards excess of loss coverages for our general liability and professional liability product lines, which resulted in higher retentions. These increases in net retention were partially offset by lower retention on our personal lines business within the Insurance segment. The decrease in net retention for the nine months ended September 30, 2018 compared to the same period of 2017 was also attributable to a decrease in net retention in the Reinsurance segment, primarily driven by higher cessions on our property product ~~lines and a decrease in gross premium volume on our whole account product line which carries a higher retention rate.~~lines.

Investing Results

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 while minimizing underwriting risk. We measure investing results by our net investment income and net investment gains as well as our taxable equivalent total investment return.

The following table summarizes our investment performance.

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

The increase in net investment income for the quarter and nine months ended September 30, ~~2018~~2019 compared to the same periods of ~~2017~~2018 was driven primarily by anhigher dividend income due to increased equity holdings and dividend rates. The increase in net investment income for the quarter ended September 30, 2019 was partially offset by a decrease in interest income on our fixed maturity portfolio, primarily due to decreased holdings of fixed maturities compared to 2018. The increase in net investment income for the nine months ended September 30, 2019 was also driven by higher short-term investment income, primarily due to higher short-term interest rates. We also recognized higher dividend income due to increased equity holdings and dividend rates and higher interest income on our fixed maturity portfolio, primarily due to increased holdings of fixed maturities. See note 4(d) of the notes to consolidated financial statements for details regarding the components of net investment income.

~~As a result of adopting ASU No. 2016-01, net~~Net investment gains for both the quarter and nine months ended September 30, ~~2018 included~~2019 were primarily attributable to an increase in the fair value of equity securities, ~~of $426.6 million and $417.4 million, respectively.~~

~~For the quarter and nine months ended September 30, 2017, the increase in the fair~~which was driven by market value ~~of equity securities, which totaled $308.3 million and $731.7 million, respectively, was included in the change in net unrealized investment gains in other comprehensive income.~~movements. See note 4(e) of the notes to consolidated financial statements for further details ~~regarding~~on the components of net investment ~~gains and the change in net unrealized gains on investments.~~gains.

Net realized investment losses for the nine months ended September 30, 2018 included losses of $41.0 million on our investment in insurance-linked securities funds (ILS Funds). Net realized investment losses for the quarter and nine months ended September 30, 2017 included losses of $51.6 million and $39.5 million, respectively, on our investment in the ILS Funds. These losses resulted from decreases in the net asset value of the ILS Funds, which were driven by the impact of losses from Hurricanes Harvey, Irma and Maria on the underlying reinsurance contracts in which the ILS Funds are invested. Net realized investment losses for the quarter and nine months ended September 30, 2017 also included write downs for other-than-temporary declines in the estimated fair value of investments of $3.4 million and $7.3 million, respectively, all of which were attributable to equity securities. There were no write downs for other-than-temporary declines in the estimated fair value of investments for the quarter and nine months ended September 30, 2018. We complete a detailed analysis each quarter to assess whether the decline in the fair value of any investment below its cost basis is deemed other-than-temporary. At September 30, 2018, we held fixed maturities with gross unrealized losses of $198.7 million, or less than 1% of invested assets. All available-for-sale securities with unrealized losses were reviewed, and we believe that there were no securities with indications of declines in estimated fair value that were other-than-temporary at September 30, 2018. However, given the volatility in the debt market, we caution readers that further declines in fair value could be significant and may result in additional other-than-temporary impairment charges in future periods. Variability in the timing of realized and unrealized gains and losses is to be expected.

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, ~~(loss),~~ such as coupon interest on fixed maturities, 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 ~~federal~~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 ~~realized and unrealized~~ 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 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 ~~and~~or amortization resulting from purchase accounting. The following table reconciles Markel Ventures operating income to Markel Ventures EBITDA.

Insurance-Linked Securities

The increase in operating revenues and operating expenses in our insurance-linked securities operations for the quarter and nine months ended September 30, 2019 compared to the same periods of ~~2017. Lower operating income and higher interest expense were largely~~2018 reflects the contribution of Nephila, which was acquired in the fourth quarter of 2018. The contribution of revenues from Nephila was partially offset by lower revenues from our Markel CATCo operations, due to lower assets under management during the quarter and nine months ended September 30, 2019 compared to the same periods of 2018 and, effective January 1, 2019, a ~~favorable impact from~~reduction in management fees charged on sidepocket shares, which represent shares that are restricted following the ~~decrease~~occurrence of catastrophic loss events for which uncertainty still exists around the ultimate incurred losses on the underlying reinsurance contracts. Additionally, operating expenses for the quarter and nine months ended September 30, 2019 were impacted by costs associated with the internal review of matters at our Markel CATCo operations and related litigation costs, the effects of which were more than offset by lower retention and incentive compensation costs in our Markel CATCo operations in 2019 compared to 2018. See note 18 of the ~~U.S. tax rate.~~notes to consolidated financial statements for further details around recent developments in our Markel CATCo operations.

Interest Expense, Loss on Early Extinguishment of Debt and Income Taxes

Interest Expense

Interest expense was ~~$38.0~~$47.5 million and ~~$114.7~~$129.0 million for the quarter and nine months ended September 30, ~~2018,~~2019, respectively, compared to ~~$31.8~~$38.0 million and ~~$97.0~~$114.7 million for the same periods of ~~2017.~~2018. The increase in interest expense for both periods of 2019 was ~~primarily~~ due to interest expense associated with our ~~4.30%~~5.0% unsecured senior notes ~~and~~which were issued in the second quarter of 2019.

Loss on Early Extinguishment of Debt

In September 2019, we purchased $125.2 million of principal on our ~~3.50%~~6.25% unsecured senior notes ~~issued in~~due September 30, 2020 and $97.8 million of principal on our 5.35% unsecured senior notes due June 1, 2021 through a tender offer at a total purchase price of $130.1 million and $103.0 million, respectively. In connection with the ~~fourth~~tender offer and purchase, we recognized a loss on early extinguishment of debt of $6.7 million during the quarter ~~of 2017. For the~~and nine months ended September 30, ~~2018, the increase was partially offset by the repayment~~2019. See "Financial Condition" for further discussion of our ~~7.20% unsecured notes in the second quarter of 2017.~~2019 senior long-term debt transactions.

Income Taxes

The effective tax rate was ~~32% for both the nine months ended September 30, 2018~~22% and ~~2017. The effective tax rate~~32% for the nine months ended September 30, 2019 and 2018, ~~reflects the impact of a change in tax status related to certain of our U.K. based operations. During the first quarter of~~respectively. In 2018, ~~after further evaluating opportunities provided by the TCJA,~~ we decided to ~~make the election~~elect to ~~have~~treat our two ~~of our~~ most significant ~~U.K.~~United Kingdom (U.K.) subsidiaries ~~treated~~ as domestic corporations for U.S. tax ~~purposes, which will enable us to manage our global capital in a more tax efficient manner. As a result, we no longer consider~~purposes. Therefore, the earnings and profits from those subsidiaries are no longer considered to be indefinitely reinvested, and ~~for~~during the nine months ended September 30, 2018, we recorded a one-time deferred tax charge of $102.0 million ~~provision for deferred U.S. income taxes on~~related to the book and tax basis differences attributable to those subsidiaries. ~~We continue to be indefinitely reinvested in our other foreign subsidiaries, with the exception of certain Bermuda-based subsidiaries.~~

We use the estimated annual effective tax rate method for calculating our tax provision in interim periods. This method applies our best estimate of the effective tax rate expected for the full year to year-to-date earnings before income taxes. Certain items, including those deemed to be unusual, infrequent or that cannot be reliably estimated (discrete items), are excluded from the estimated annual effective tax rate, and the related tax expense or benefit is reported in the same period as the related item. Therefore, we also analyzed our estimated annual effective tax rate, which excludes the impact of these items. The following table summarizes our effective tax rate and estimated annual effective tax rate for the nine months ended September 30, ~~2018~~2019 and ~~2017.~~2018.


	Nine Months Ended September 30,				Nine Months Ended September 30,
	2018		2017		2019		2018
Effective tax rate	32	%	32	%	22	%	32	%

Impact of other discrete items					(1	)	(1	)
Estimated annual effective tax rate	20	%	28	%	21	%	20	%

For the nine months ended September 30, 2018, the estimated annual effective tax rate was 20%. This differs from the U.S. statutory tax rate of 21% primarily as a result of tax-exempt investment income. For the nine months ended September 30, 2017, the estimated annual effective tax rate of 28% differs from the U.S. statutory tax rate of 35% primarily as a result of tax-exempt investment income. The decrease in the estimated annual effective tax rate for the nine months ended September 30, 2018 compared to the same period of 2017 was primarily attributable to the decrease in the U.S. corporate tax rate from 35% to 21% resulting from the TCJA, partially offset by the impact of having higher pre-tax income for the nine months ended September 30, 2018, which reduced the net favorable impact of certain tax adjustments.

~~Effect~~ive January 1, 2018, the Company adopted ASU No. 2016-01 and equity securities are no longer classified as available-for-sale with unrealized gains and losses recognized in other comprehensive income. Rather, all changes in fair value of equity securities are now recognized in net income. For the quarter and nine months ended September 30, 2018, the change in fair value of equity securities included in net income was a gain of $426.6 million and $417.4 million, respectively, compared to gains of $308.3 million and $731.7 million for the quarter and nine months ended September 30, 2017, respectively, included in other comprehensive income. This change in presentation has no impact on comprehensive income to shareholders.

In January~~2018. During the nine months ended September 30, 2019, we issued unsecured senior notes with net proceeds of $1.4 billion, before expenses. We used a portion of these proceeds to repay the remaining outstanding balance of our 7.125% unsecured senior notes due September 30, 2019 ($234.8 million aggregate principal outstanding at December 31, 2018). We used an additional portion of these proceeds to purchase $223.0 million of principal on two additional series of our other unsecured senior notes through a tender offer at a total purchase price of $233.1 million. See note 11 of the notes to consolidated financial statements for more details regarding the components of senior long-term debt. During the nine months ended September 30, 2018, we repaid $37.5 million of the outstanding note payable that was delivered as part of the consideration provided for the investment held by the Markel Diversified Fund as ~~discussed in note 11 of the notes to consolidated financial statements. During the first nine months of 2018, we also repaid~~well as $44.5 million of debt assumed in connection with the 2017 acquisition of State ~~National.

In August 2019, our Board of Directors approved a new share repurchase program (the 2019 Program) to replace the previous share repurchase program. Consistent with the previous program, the 2019 Program provides for the repurchase of up to $300 million of common stock and has no expiration date but may be terminated by the Board of Directors at any time. As of September 30, 2019, we had repurchased 4,620 shares of common stock under the 2019 program at a cost of $5.4 million.

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%~~27% at September 30, ~~2018~~2019 and 25% at December 31, ~~2017.~~2018.

In October 2019, we redeemed an additional $377.0 million of principal on two series of our unsecured senior notes for a total purchase price of $393.6 million.

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 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 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 recent developments at our Markel CATCo operations. See note 18 of the notes to consolidated financial statements for more details regarding the Markel CATCo developments.

In ~~August 2018,~~April 2019, we entered into a ~~definitive~~credit agreement for a new revolving credit facility, which provides up to ~~acquire all~~$300 million of capacity for future acquisitions, investments and stock repurchases and for other working capital and general corporate purposes. At our discretion, up to $200 million of the ~~outstanding shares~~total capacity may be used for letters of ~~Nephila Holdings Limited (Nephila), a Bermuda-based investment manager offering a broad range~~credit. This facility replaced our previous $300 million revolving credit facility and expires in April 2024. See note 11 of ~~investment products, including insurance-linked securities, catastrophe bonds, insurance swaps and weather derivatives. Total consideration~~the notes to consolidated financial statements for ~~this acquisition is estimated to be $975.0 million, all of which is expected to be paid in cash.

In October 2018, we acquired 90% of Brahmin Leather Works (Brahmin), a Massachusetts-based privately held creator of fashion leather handbags. Total consideration for the acquisition of Brahmin included cash consideration of $173.3 million.

Our holding company had ~~$3.1~~$3.3 billion and ~~$2.7~~$2.6 billion of invested assets at September 30, ~~2018~~2019 and December 31, ~~2017,~~2018, respectively. The increase in invested assets is primarily due to ~~dividends received~~the net proceeds from the issuance of our ~~subsidiaries,~~new unsecured senior notes during the nine months ended September 30, 2019, partially offset by ~~interest payments associated with our~~the repayment and purchase of certain unsecured senior notes, as described above, and ~~loans and capital contributions made~~cash used to ~~our subsidiaries.~~acquire a minority ownership interest in Hagerty Group.

Brexit Developments

On June 23, 2016, the U.K. voted to exit the European Union (E.U.) (Brexit), ~~and on March 29, 2017, the U.K. government delivered formal notice~~which was originally set to the other E.U. member states that it is leaving the E.U. A two-year period then commenced during which the U.K. and the E.U. are negotiating the future terms of the U.K.'s relationship with the E.U., including the terms of trade between the U.K. and the E.U. Unless this period is extended, the U.K. will automatically exit the E.U., with or without an agreement in place, after two yearsoccur on March 29, 2019. During this period the U.K. remains a part of the E.U. If Brexit terms are agreed and ratified, Brexit could be implemented in stages over a multi-year transitional period. No member state has left the E.U., and the rules for exit (contained in Article 50 of the Treaty on European Union) are brief. The U.K. and the E.U. have agreed to certain Brexit terms, including the financial settlement to be paid by the U.K. upon leaving the E.U. and a transitional period that would last until December 31, 2020 and provide the U.K. and the E.U. additional time to prepare for the post-Brexit period. However, the U.K. and the E.U. still must agree on the terms of the future relationship between the U.K. and the E.U., including matters such as trade, travel and security, and all Brexit terms must be ratified by the U.K. Parliament and the legislative bodies of the remaining 27 E.U. member states.

Accordingly, there are significant uncertainties related to the political, monetary and economic impacts of Brexit, including related tax, accounting and financial reporting implications. Brexit could also lead to legal uncertainty and potentially a large number of new and divergent national laws and regulations, including new tax rules, as the U.K. determines which E.U. laws to replace or replicate.

The effects of Brexit will depend in part on agreements, if any, the U.K. makes to retain access to E.U. ~~markets either during~~markets. For over two years the U.K. and E.U. have been negotiating the future terms of the U.K.’s relationship with the E.U., including the terms of trade between the U.K. and the E.U. On April 10, 2019, the E.U. granted the U.K. an extension until October 31, 2019 to allow the U.K. to ratify a ~~transitional period~~proposed agreement between the E.U. and the U.K. for the orderly exit of the U.K. from the E.U.

A renegotiated agreement was agreed between the U.K. government and the E.U. in October 2019. The U.K. Parliament approved the agreement in principle, but requested an additional extension to allow the U.K. Parliament to consider the proposed agreement further. The E.U. granted a further extension to January 31, 2020. The U.K. Parliament must fully ratify this new proposed agreement or ~~more permanently.~~ the U.K. will leave the E.U. without an agreement when the extension expires. Under the proposed agreement, the final terms of the future relationship between the U.K. and the E.U. remain to be negotiated. Ultimately, all Brexit terms also must be ratified by the legislative bodies of the 27 E.U. member states.

Brexit could impair or end the ability of both Markel International Insurance Company Limited (MIICL) and our ~~Lloyd's~~Lloyd’s syndicate to transact business in E.U. ~~member states~~countries from our U.K. offices and ~~MIICL's~~MIICL’s ability to maintain its current branches in E.U. member ~~states and in Switzerland.~~

states. In order to continue transacting E.U. business if U.K. access to E.U. markets ceases or is materially impaired, we have established a regulated insurance carrier, Markel Insurance SE (MISE), in Munich, Germany. From its offices in Germany, MISE can transact business in all remaining E.U. member states and throughout the European Economic Area (EEA). MISE ~~is also establishing~~has established branches in Ireland, the Netherlands, Spain, ~~Switzerland~~ and the U.K. ~~However, the regulatory regime for the MISE branch in the U.K. is uncertain and may impact our Brexit mitigation plans.~~ In addition, ~~The~~the Society of ~~Lloyd's~~Lloyd’s has organized a new insurance company in Brussels, Belgium, in order to maintain access to E.U. business for ~~Lloyd's~~Lloyd’s syndicates. We expect that the new Lloyd’s Brussels insurance company will supplement, or serve as an alternative to, MISE for access to E.U. markets.

Without a Brexit agreement, U.K. based insurers may be prohibited from administering policies for, or paying claims to, EEA policyholders post Brexit. In order to provide certainty for its EEA policyholders, MIICL ~~intends to transfer~~transferred its legacy EEA exposures, claims and policies to ~~MISE to provide certainty for MIICL’s policyholders if MIICL were to be prevented from paying claims and administering policies post Brexit. However, this~~MISE. This transfer ~~must be~~was approved by the U.K. High Court and became effective on March 29, 2019. Lloyd’s also has commenced its transfer of legacy EEA exposures. However, that transfer is not expected to be completed prior to January 31, 2020, and there is no ~~certainty~~assurance that ~~this~~ approval of that transfer will be granted or on what terms and conditions. Lloyd’s has indicated that it intends to honor contractual commitments, including the payment of valid claims, and expects that its approach will be respected by EEA regulators pending the completion of its transfer of legacy EEA exposures. The European Insurance and Occupational Pensions Authority has issued its recommendation to E.U. member states that they adopt legislation to permit the orderly run-off of legacy EEA exposures, claims and policies by U.K. insurers. While some E.U. member states have adopted such legislation, no E.U. member state is obligated to do so, and the terms of any such legislation may vary significantly among the E.U. member states. Without an orderly run-off regime for legacy business in every E.U. member state, Lloyd’s, and in turn, our Lloyd’s syndicate, may be impaired in running-off business, including paying claims, in the E.U. member states.

~~Disclosure of Certain Activities Relating to Iran~~

Under the Iran Threat Reduction and Syria Human Rights Act of 2012, non-U.S. entities owned or controlled by U.S. persons have been prohibited from engaging in activities, transactions or dealings with Iran to the same extent as U.S. persons. Effective January 16, 2016, the Office of Foreign Assets Control of the U.S. Department of the Treasury (OFAC) issued General License H, which authorized non-U.S. entities that are owned or controlled by a U.S. person to engage in most activities with Iran permitted for other non-U.S. entities so long as they met certain requirements.

On May 8, 2018, President Trump announced that the United States would no longer participate in the Joint Comprehensive Plan of Action, which was intended to ensure that Iran’s nuclear program remains peaceful. As a result, all previously suspended sanctions will “snap back” into effect. On June 27, 2018, OFAC revoked General License H and, at the same time, issued a license authorizing, through November 4, 2018, foreign entities owned or controlled by a U.S. person to engage in “all transactions and activities that are ordinarily incident and necessary to the wind-down” of transactions previously authorized under General License H (the Wind-Down License).

Section 13(r) of the Securities Exchange Act of 1934 requires reporting of certain Iran-related activities, including underwriting, insuring and reinsuring certain activities previously permitted under General License H related to the importation of refined petroleum products by Iran and vessels involved in the transportation of crude oil from Iran.

Certain of our non-U.S. insurance operations underwrite global marine hull policies and global marine hull war policies that provide coverage for vessels or fleets navigating into and out of ports worldwide, potentially including Iran under policies entered into before May 8, 2018. Under a global marine hull war policy, the insured is required to give notice before entering designated areas, including Iran. During the quarter ended September 30, 2018, we received notice that one or more vessels covered by a global marine hull war policy were entering Iranian waters. However, no additional premium is required under global marine hull policies or global marine hull war policies for calling into Iran. During the quarter ended September 30, 2018, we were not asked to cover a specific voyage into or out of Iran that would result in a separate, allocable premium for that voyage.

Certain of our non-U.S. reinsurance operations underwrite marine, energy, aviation and trade credit liability treaties on a worldwide basis and, as a result, it is possible that the underlying insurance portfolios may have exposure to the Iranian petroleum industry and its related products and service providers under reinsurance treaties entered into before May 8, 2018.

Prior to May 8, 2018, we entered into two energy construction reinsurance contracts in Iran, two Iran-related marine liability contracts, two Iran-related marine cargo contracts and one Iran-related hull war contract. These contracts were underwritten through our syndicate at Lloyd's and one of our non-U.S. insurance companies. Our portion of the annual premium for these contracts was approximately $1 million in the aggregate. Except for these contracts, we are not aware of any premium apportionment with respect to underwriting, insurance or reinsurance activities of our non-U.S. insurance subsidiaries reportable under Section 13(r). Should any such risks have entered into the stream of commerce covered by the insurance portfolios underlying our reinsurance treaties, we believe that the premiums associated with such business were immaterial.

Since May 8, 2018, our non-U.S. subsidiaries, including our non-U.S. insurance subsidiaries, have not entered into any new transactions that had previously been permitted under General License H. With respect to activities, transactions or dealings with Iran, our non-U.S. subsidiaries are now engaging only in "transactions and activities that are ordinarily incident and necessary to the wind-down" of transactions previously authorized under General License H in the manner permitted under, and in accordance with, the Wind-Down License or other applicable economic or trade sanctions requirements or licenses.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market Risk Disclosures

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 have been equity price risk associated with investments in equity securities, interest rate risk associated with investments in fixed maturities and foreign currency exchange rate risk associated with our international operations. ~~Various companies~~Some businesses within our Markel Ventures operations are ~~subject~~exposed to commodity price ~~risk;~~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.

We have foreign currency exchange rate risk associated with certain of our assets and liabilities. We manage this risk primarily by matching assets and liabilities in each foreign currency as closely as possible. However, the carrying value of non-monetary assets and liabilities, such as goodwill and intangible assets, of certain foreign operations is not matched or hedged. As of September 30, 2018 and December 31, 2017, the carrying value of goodwill and intangible assets related to these foreign operations was $134.5 million and $225.9 million, respectively. The decrease is due to the reassessment of our functional currency determination as of January 1, 2018, resulting in the U.S. Dollar being the only functional currency for most of our foreign underwriting operations. Consequently, goodwill and intangible assets of certain foreign operations denominated in a currency other than the U.S. Dollar are now remeasured into the U.S. Dollar at historic exchange rates and are no longer impacted by changes in foreign currency exchange rates.

During the nine months ended September 30, ~~2018,~~2019, there were no ~~other~~ material changes to the market risk components described in our Annual Report on Form 10-K for the year ended December 31, ~~2017.~~2018.

The estimated fair value of our investment portfolio at September 30, ~~2018~~2019 was ~~$21.0~~$21.9 billion, ~~69%~~68% of which was invested in fixed maturities, short-term investments, cash and cash equivalents and restricted cash and cash equivalents and ~~31%~~32% of which was invested in equity securities. At December 31, ~~2017,~~2018, the estimated fair value of our investment portfolio was ~~$20.6~~$19.2 billion, ~~71%~~70% of which was invested in fixed maturities, short-term investments, cash and cash equivalents and restricted cash and cash equivalents and ~~29%~~30% of which was invested in equity securities.

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. We monitor our investment portfolio to ensure that credit risk does not exceed prudent levels. We have consistently invested in high credit quality, investment grade securities. Our fixed maturity portfolio has an average rating of "AA," with 98% 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 maturities that are unrated or rated below investment grade. At September 30, ~~2018,~~2019, 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 maturities based on our assessment of the credit quality of the underlying assets without regard to insurance.

Our fixed maturity portfolio includes securities issued by foreign governments and non-sovereign foreign institutions. General concern exists about the financial difficulties facing certain foreign countries in light of the adverse economic conditions experienced over the past several years. We monitor developments in foreign countries, currencies and issuers that could pose risks to our fixed maturity portfolio, including ratings downgrades, political and financial changes and the widening of credit spreads. We believe that our fixed maturity portfolio is highly diversified and is comprised of high quality securities. During the nine months ended September 30, ~~2018,~~2019, there were no material changes in our foreign government fixed maturity holdings.

General concern ~~also~~ exists about municipalities that experience financial difficulties during periods of adverse economic conditions. We manage the exposure to credit risk in our municipal bond portfolio by investing in high quality securities and by diversifying our holdings, which are typically either general obligation or revenue bonds related to essential products and services.

Our fixed maturities, equity securities and short-term investments are recorded at fair value, which is measured based upon quoted prices in active markets, if available. We determine fair value for these investments after considering various sources of information, including information provided by a ~~third-party~~third party pricing service. The pricing service provides prices for substantially all of our fixed maturities and equity securities. In determining fair value, we generally do not adjust the prices obtained from the pricing service. We obtain 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. We validate prices provided by the pricing service by reviewing prices from other pricing sources and analyzing pricing data in certain instances.

Item 4. Controls and Procedures

As of the end of the period covered by this quarterly report, we carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Securities Exchange Act Rule 13a-15 (Disclosure Controls). 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).

Our management, including the Co-PEOs and PFO, does not expect that our Disclosure Controls will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision making can be faulty, and that breakdowns can occur because of simple error or mistake. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Based upon our controls 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 Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms.

There were no changes in our internal control over financial reporting during the third quarter of ~~2018~~2019 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

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"~~Factors," "Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Safe Harbor and Cautionary Statement" in our ~~2017~~2018 Annual Report on Form 10-K and under "Risk Factors" in this report, or are included in the items listed below:

our expectations about future results of our underwriting, investing, Markel Ventures and other operations are based on current knowledge and assume no significant man-made or natural catastrophes, no significant changes in products or personnel and no adverse changes in market conditions;

the effect of cyclical trends on our underwriting, investing, Markel Ventures and other operations, including demand and pricing in the insurance, reinsurance and other markets in which we operate;

actions by competitors, including the application of new or "disruptive" technologies or business models and consolidation, and the effect of competition on market trends and pricing;

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;

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

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;

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 ~~failure or inadequacy~~nature and extent of ~~any loss limitation methods we employ;~~losses, coverage, liability and reinsurance, and those losses may ultimately differ materially from our expectations;

changes in the availability, costs and quality of reinsurance coverage, which may impact our ability to write or continue to write certain lines of business;

the ability or willingness of reinsurers to pay balances due may be adversely affected by industry and economic conditions, deterioration in reinsurer credit quality and coverage disputes, and collateral we hold, if any, may not be sufficient to cover a reinsurer's obligation to us;

after the commutation of ceded reinsurance contracts, any subsequent adverse development in the re-assumed loss reserves will result in a charge to earnings;

regulatory actions can impede our ability to charge adequate rates and efficiently allocate capital;

general economic and market conditions and industry specific conditions, including extended economic recessions or expansions; prolonged periods of slow economic growth; inflation or deflation; fluctuations in foreign currency exchange rates, commodity and energy prices and interest rates; volatility in the credit and capital markets; and other factors;

economic conditions, actual or potential defaults in municipal bonds or sovereign debt obligations, volatility in interest and foreign currency exchange rates and changes in market value of concentrated investments can have a significant impact on the fair value of our fixed maturity and equity securities, as well as the carrying value of our other assets and liabilities, and this impact may be heightened by market volatility;

economic conditions may adversely affect our access to capital and credit markets;

the effects of government intervention, including material changes in the monetary policies of central banks, to address financial downturns and economic and currency concerns;

the impacts that political and civil unrest and regional conflicts may have on our businesses and the markets they serve or that any disruptions in regional or worldwide economic conditions generally arising from these situations may have on our businesses, industries or investments;

the impacts that health epidemics and pandemics may have on our business operations and claims activity;

the impact on our businesses in the event of ~~the~~a repeal, in part or in whole, or modification of U.S. health care reform legislation and regulations;

changes in U.S. tax laws, regulations or interpretations, including those relating to the Tax Cuts and Jobs Act, or in the tax laws, regulations or interpretations of other jurisdictions in which we operate and adjustments we may make in our operations or tax strategies in response to those changes;

a failure of our enterprise information technology systems orand those ofmaintained by third parties upon which we may rely, or a failure to comply with data protection or privacy regulations;

our acquisitions may increase our operational and control risks for a period of time;

we may not realize the contemplated benefits, including cost savings and synergies, of our acquisitions;

any determination requiring the write-off of a significant portion of our goodwill and intangible assets;

the failure or inadequacy of any loss limitation methods we employ;

the loss of services of any executive officer or other key personnel could adversely impact one or more of our operations;

our substantial international operations and investments expose us to increased political, operational and economic risks, including foreign currency exchange rate and credit risk;

the political, legal, regulatory, financial, tax and general economic impacts, and other impacts we cannot anticipate, related to the vote by the United Kingdom to leave the European Union (Brexit), which could have adverse consequences for our businesses, particularly our London-based international insurance operations;

our ability to obtain additional capital for our operations on terms favorable to us;

our compliance, or failure to comply, with covenants and other requirements under our revolving credit facility, senior debt and other indebtedness;

our ability to maintain or raise third party capital for existing or new investment vehicles and risks related to our management of third party capital;

the effectiveness of our procedures for compliance with existing and ~~ever increasing~~future guidelines, policies and legal and regulatory standards, rules, laws and regulations;

the impact of economic and trade sanctions and embargo programs on our businesses, including instances in which the requirements and limitations applicable to the global operations of U.S. companies and their affiliates are more restrictive than, or conflict with, those applicable to non-U.S. companies and their affiliates;

regulatory changes, or challenges by regulators, regarding the use of certain issuing carrier or fronting arrangements;

our dependence on a limited number of brokers for a large portion of our ~~revenues;~~revenues and third-party capital;

adverse changes in our assigned financial strength or debt ratings could adversely impact us, including our ability to attract and retain business, the amount of capital our insurance subsidiaries must hold and the availability and cost of capital;

changes in the ~~political, legal,~~amount of statutory capital our insurance subsidiaries are required to hold, which can vary significantly and is based on many factors outside our control;

losses from litigation and regulatory ~~financial, tax~~investigations and ~~general economic impacts, and others we cannot anticipate, of Brexit;~~actions; and

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 market; liability for environmental matters; volatility in the market prices for their products; and volatility in commodity prices and interest and foreign currency exchange rates.

Our premium volume, underwriting and investment results and results from our other operations have been and will continue to be potentially materially affected by these factors. In addition, with respect to previously reported developments at MCIM and the decision to place both the Markel CATCo Funds and 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.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

~~Thomas Yeransian~~Markel CATCo Inquiries

We previously reported that the U.S. Department of Justice, U.S. Securities and Exchange Commission and Bermuda Monetary Authority (together, the Governmental Authorities) are conducting inquiries into loss reserves recorded in late 2017 and early 2018 at our Markel CATCo operations. Those reserves are held at Markel CATCo Re, an unconsolidated subsidiary of MCIM. The Markel CATCo Inquiries are limited to MCIM and its subsidiaries and do not involve other Markel subsidiaries.

We retained outside counsel to conduct an internal review of Markel CATCo’s loss reserving in late 2017 and early 2018. The internal review was completed in April 2019 and found no evidence that Markel CATCo personnel acted in bad faith in exercising business judgment in the setting of reserves and making related disclosures during late 2017 and early 2018. Our outside counsel has met with the Governmental Authorities and reported the findings from the internal review.

The Markel CATCo Inquiries are ongoing and we continue to fully cooperate with the Governmental Authorities. At this time, we are unable to predict the duration, scope or result of the Markel CATCo Inquiries.

Markel Securities Litigation

Between January 11, 2019 and March 7, 2019, several related putative class actions were filed in the U.S. District Court for the Southern District of New York against Markel Corporation and certain present or former officers and directors alleging violations of the federal securities laws relating to the matters that are the subject of the Markel CATCo Inquiries. Plaintiffs sought to represent a class of persons or entities that purchased Markel securities between July 26, 2017 and December 6, 2018. The actions were consolidated. The plaintiff in the consolidated action voluntarily dismissed that action without prejudice on August 6, 2019.

Belisle Arbitration

On February 21, 2019, Anthony Belisle filed a lawsuit, Anthony Belisle v. Markel ~~Corporation~~CATCo Investment Management Ltd and Markel Corp. (U.S. District Court for the District of ~~Delaware)~~New Hampshire), which suit was amended on March 29, 2019. As amended, the complaint alleged claims for, among other things, breach of contract, defamation, invasion of privacy, indemnification, intentional interference with contractual relations and deceptive and unfair acts and sought relief of, among other things, $66.0 million in incentive compensation, enhanced compensatory damages, consequential damages, damages for emotional distress and injury to reputation, exemplary damages and attorneys' fees. In June 2019, MCIM, Markel Corporation, and Mr. Belisle agreed to commence binding arbitration to finally, fully and confidentially resolve the claims and counterclaims alleged in the action, and the Belisle suit was dismissed with prejudice in July 2019. The arbitrators have been selected and the arbitration proceeding has commenced. We believe that Mr. Belisle's claims are without merit.

Thomas Yeransian v. Markel Corporation

In October 2010, we completed ~~our~~the acquisition of Aspen Holdings, Inc. (Aspen). As part of the consideration for that acquisition, Aspen shareholders received contingent value rights (CVRs). Based on a valuation of the CVRs as of their December 31, 2017 maturity date, we paid $9.9 million to the CVR holders on June 5, 2018, which represents 90% of the undisputed portion of the final amount we believe we are required to pay under the CVR agreement.

Prior to the December 31, 2017 CVR maturity date, the CVR holder representative, Thomas Yeransian, had disputed our prior estimation of the value of the CVRs. On September 15, 2016, Mr. Yeransian filed a suit, Thomas Yeransian v. Markel Corporation (U.S. District Court for the District of Delaware), alleging, among other things, that we are in default under the CVR agreement. The ~~holder representative~~suit seeks: $47.3 million in damages, which represents the unadjusted value of the CVRs; plus interest ($~~13.4~~16.4 million through September 30, ~~2018)~~2019) and default interest (up to an additional ~~$11.5~~$13.6 million through September 30, ~~2018,~~2019, depending on the date any default occurred); and an unspecified amount of punitive damages, costs, and attorneys’ fees.

At the initial hearing held February 21, 2017, the court stayed the proceedings and ordered the parties to discuss resolving the dispute pursuant to the independent CVR valuation procedure under the CVR agreement. The parties met on April 5, 2017, but were unsuccessful in reaching agreement on a process for resolving the dispute. We subsequently filed a motion to stay the litigation and compel arbitration, and, on July 31, 2017, the court issued an order granting that motion. ~~Mr. Yeransian has filed a motion requesting that the court reconsider that order.~~

On September 20, 2018, a new judge was assigned to the case. On October 12, 2018, the court denied both Mr. Yeransian's motion to reconsider the order staying the litigation and compelling arbitration and aour motion ~~by the Company~~ for sanctions against Mr. Yeransian for violating the confidentiality of mediation proceedings. ~~Two motions are pending before~~The court subsequently (1) on December 3, 2018 ordered Mr. Yeransian to provide the ~~court:~~court and us with the ~~Company’s motion~~identity of an actuarial firm to ~~dismiss~~participate in the ~~case~~selection of independent experts for ~~Yeransian's violation of~~ the ~~order staying~~CVR valuation process under the ~~litigation~~CVR agreement and ~~compelling arbitration; and~~(2) on December 11, 2018 denied Mr. Yeransian's motion for judgment that ~~the Company has~~we had waived ~~its~~our right to require Mr. Yeransian's participation in the ~~arbitration.~~CVR valuation process. On July 8, 2019, the Court granted our motion for instructions as to how the independent experts are to conduct the CVR valuation process and denied Mr. Yeransian’s motion to have a hearing officer appointed to oversee the valuation process. The independent experts, who were jointly selected by the parties, have been engaged for the valuation process.

On November 13, 2018, Mr. Yeransian filed a second suit, Thomas Yeransian v. Markel Corporation (U.S. District Court for the District of Delaware), which also alleges that the Company is in default under the CVR agreement. The second suit seeks the same damages and relief as the original suit. We filed a motion to stay this suit until the arbitration for the original suit has concluded and the CVR holders have received the remainder of the final amount due under the CVR Agreement. The court granted that motion on August 6, 2019.

We believe ~~the holder representative’s suit~~Mr. Yeransian's suits to be without ~~merit and will vigorously defend against it.~~merit. We further believe that any material loss resulting from the ~~holder representative’s suit~~suits to be remote. We do not believe the contractual contingent consideration payments related to the CVRs will have a material impact on ~~our~~the Company’s liquidity.

Additional information regarding legal proceedings can be found under “Legal Proceedings” in our 2018 Annual Report on Form 10-K and our Quarterly Reports on Form 10-Q for the quarters ended June 30, 2019 and March 31, 2019.

Item 1A. Risk Factors

Other than the risk factor discussed below, or as discussed in note 18 (Commitments and Contingencies) of the notes to consolidated financial statements or under "Brexit Developments" or "Legal Proceedings" in this report, there have been no material changes with regard to the risk factors previously disclosed in our 2018 Annual Report on Form 10-K.

The effects of emerging claim and coverage issues on our business are uncertain. As industry practices and legal, judicial, social and other environmental conditions change, unexpected and unintended issues related to claims and coverage may emerge. These issues may have a material adverse effect on our business by either broadening coverage beyond our underwriting intent or by increasing the number or size of claims. In some instances, these changes may not become apparent until after we have issued insurance or reinsurance contracts that are affected by the changes. As a result, the full extent of liability under our insurance or reinsurance contracts may not be known for many years after a contract is issued. For example, many states have recently extended the statute of limitations for certain victims of sexual abuse. This may result in a higher frequency of claims over a more extended reporting period than originally expected.

For other factors that may cause actual results to differ materially from those indicated in any forward-looking statement contained in this report, see "Safe Harbor and Cautionary Statement".

The Board of Directors approved the repurchase of up to $300 million of our common stock pursuant to a share repurchase program publicly announced on August 21, 2019 (the 2019 Program). The 2019 Program terminated and replaced a similar $300 million program authorized on May 14, 2018 (the 2018 Program). Under the 2019 Program, as under the 2018 Program, we may repurchase outstanding shares of our common stock from time to time in privately negotiated or open market transactions, including under plans complying with Rule 10b5-1 under the Securities Exchange Act of 1934. The 2019 Program has no expiration date, but may be terminated by the Board of Directors at any time. As of August 21, 2019, no further share repurchases may be made under the 2018 Program; future share repurchases will be made pursuant to the 2019 Program.
