MARKEL CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Basis of Presentation

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

The consolidated balance sheet as of June 30, 2015, the related consolidated statements of income and comprehensive income (loss) for the quarters and six months ended June 30, 2015 and 2014, and the consolidated statements of changes in equity and cash flows for the six months ended June 30, 2015 and 2014 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, 2014 was derived from Markel Corporation's audited annual consolidated financial statements.

The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) and include the accounts of Markel Corporation and its subsidiaries (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. 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 2014 Annual Report on Form 10-K for a more complete description of the Company's business and accounting policies.

2. Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606), which creates a new comprehensive revenue recognition standard that will serve as a single source of revenue guidance for all companies in all industries. The guidance applies to all companies that either enter into contracts with customers to transfer goods or services or enter into contracts for the transfer of nonfinancial assets, unless those contracts are within the scope of other standards, such as insurance contracts. ASU No. 2014-09's core principle is that a company will recognize 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 doing so, companies will need to use more judgment and make more estimates than under the current guidance. These may include 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. ASU No. 2014-09 becomes effective for the Company during the first quarter of 2017 and may be applied retrospectively or under a modified retrospective method where the cumulative effect is recognized at the date of initial application. Early application is not permitted. In July 2015, the FASB approved a proposed one-year deferral of the effective date for ASU 2014-09. Under the final ASU, which has not yet been issued, early application would be permitted for all entities, but not before the original effective date for public business entities. The Company is currently evaluating ASU No. 2014-09 to determine the potential impact that adopting this standard will have on its consolidated financial statements. Adoption of this ASU is not expected to have a significant impact on the Company's insurance operations, but will impact the Company's non-insurance operations.

Table of Contents

In February 2015, the FASB issued ASU No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis, which changes the way reporting enterprises evaluate whether (a) they should consolidate limited partnerships and similar entities, (b) fees paid to a decision maker or service provider are variable interests in a variable interest entity (VIE), and (c) variable interests in a VIE held by related parties of the reporting enterprise require the reporting enterprise to consolidate the VIE. It also eliminates the VIE consolidation model based on majority exposure to variability that applied to certain investment companies and similar entities. The ASU also significantly changes how to evaluate voting rights for entities that are not similar to limited partnerships when determining whether the entity is a VIE, which may affect entities for which the decision making rights are conveyed through a contractual arrangement. ASU No. 2015-02 becomes effective for the Company during the first quarter of 2016 and may be applied retrospectively or under a modified retrospective method where the cumulative-effect adjustment to retained earnings is recognized as of the beginning of the fiscal year of adoption. Reporting enterprises may also restate previously issued financial statements for one or more years with a cumulative-effect adjustment to retained earnings as of the beginning of the first year restated. Early adoption is allowed. The Company is currently evaluating ASU No. 2015-02 but does not expect adoption of this ASU will have a material impact on the Company's financial position, results of operations or cash flows.

In April 2015, the FASB issued ASU No. 2015-03, Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The ASU requires that debt issuance costs related to a recognized debt liability be presented on the balance sheet as a direct deduction from the debt liability, similar to the presentation of debt discounts. The cost of issuing debt will no longer be recorded as a separate asset on the balance sheet. The amortization of debt issuance costs will continue to be included in interest expense. ASU No. 2015-03 becomes effective for the Company during the first quarter of 2016 and will be applied retrospectively to all prior periods presented. Early application is permitted. The adoption of this ASU is not expected to have a material impact on the Company’s financial position, results of operations or cash flows.

In April 2015, the FASB issued ASU No. 2015-05, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer's Accounting for Fees Paid in a Cloud Computing Arrangement, which clarifies that software licenses contained in a cloud computing arrangement should be capitalized if the customer has the right to take possession of the software and the ability to run the software outside of the cloud computing arrangement. ASU No. 2015-05 becomes effective for the Company during the first quarter of 2016 and may be applied prospectively or retrospectively. Early application is permitted. The adoption of this ASU is not expected to have a material impact on the Company’s financial position, results of operations or cash flows.

In May 2015, the FASB issued ASU No. 2015-09, Financial Services-Insurance (Topic 944): Disclosures about Short-Duration Contracts. The ASU requires significant new disclosures for insurers relating to short-duration insurance contract claims and the unpaid claims liability rollforward for long and short-duration contracts. The guidance requires annual tabular disclosure, on a disaggregated basis, of undiscounted incurred and paid claim and allocated claim adjustment expense development by accident year, on a net basis after reinsurance, for up to 10 years. Tables must also include the total incurred but not reported claims liabilities, plus expected development on reported claims, and claims frequency for each accident year. A description of estimation methodologies and any significant changes in methodologies and assumptions used to calculate the liability and frequency is also required. Based on the disaggregated claims information in the tables, disclosure of historical average annual percentage payout of incurred claims is also required. Interim period disclosures must include a tabular rollforward and related qualitative information for the liability for unpaid losses and loss adjustment expenses for both long-duration and short-duration contracts. ASU No. 2015-09 becomes effective for the Company during 2016, with interim disclosures required beginning in the first quarter of 2017. The ASU must be applied retrospectively by providing comparative disclosures for each period presented. Early application is permitted. The adoption of this ASU is not expected to have a material impact on the Company’s financial position, results of operations or cash flows, but will expand the nature and extent of its insurance contract disclosures as described above.

At December 31, 2014, the Company held 552 securities with a total estimated fair value of $2.0 billion and gross unrealized losses of $35.2 million. Of these 552 securities, 396 securities had been in a continuous unrealized loss position for one year or longer and had a total estimated fair value of $1.3 billion and gross unrealized losses of $22.1 million. All 396 securities were fixed maturities.

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 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 equity securities, the ability and intent to hold the security for a period of time sufficient to allow for anticipated recovery is considered. 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 equity securities, a decline in fair value that is considered to be other-than-temporary 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. 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 (loss). 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.

Table of Contents

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.

4. Fair Value Measurements

FASB ASC 820-10, 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 FASB 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

Table of Contents

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. Investments available-for-sale are recorded at fair value on a recurring basis and include fixed maturities, equity securities and short-term investments. Short-term investments include certificates of deposit, commercial paper, discount notes and treasury bills with original maturities of one year or less. Fair value for investments available-for-sale is 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 and obligations of U.S. government agencies, municipal bonds, foreign government bonds, commercial mortgage-backed securities, residential mortgage-backed securities, asset-backed securities and corporate debt securities.

Fair value for investments available-for-sale 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.

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.

5. Segment Reporting Disclosures

The Company monitors and reports its ongoing underwriting operations in the following three segments: U.S. Insurance, International Insurance and Reinsurance. In determining how to aggregate and monitor its underwriting results, the Company considers many factors, including the geographic location and regulatory environment of the insurance entity underwriting the risk, the nature of the insurance product sold, the type of account written and the type of customer served. The U.S. Insurance segment includes all direct business and facultative placements written by the Company's insurance subsidiaries domiciled in the United States. The International Insurance segment includes all direct business and facultative placements written by the Company's insurance subsidiaries domiciled outside of the United States, including the Company's syndicate at Lloyd's of London. 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 the results attributable to the run-off of life and annuity reinsurance business, are reported in the Other Insurance (Discontinued Lines) segment. All investing activities related to the Company's insurance operations are included in the Investing segment.

The Company's non-insurance operations include the Company's Markel Ventures operations, which primarily consist of controlling interests in various industrial and service businesses. The Company's non-insurance operations also include the results of the Company's legal and professional consulting services. For purposes of segment reporting, the Company's non-insurance operations are not considered to be a reportable segment.

Segment profit for the Investing segment is measured by net investment income and net realized investment gains or losses. Segment profit or loss for each of the Company's underwriting segments is measured by underwriting profit or loss. 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. Underwriting profit or loss 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 or loss for the Company's underwriting segments also includes other revenues and other expenses, primarily related to the run-off of managing general agent operations that were discontinued in conjunction with acquisitions. Other revenues and other expenses in the Other Insurance (Discontinued Lines) segment are comprised of the results attributable to the run-off of life and annuity reinsurance business.

For management reporting purposes, the Company allocates assets to its underwriting, investing and non-insurance operations. Underwriting assets are all assets not specifically allocated to the Investing segment or to the Company's non-insurance operations. Underwriting and investing assets are not allocated to the U.S. Insurance, International Insurance, Reinsurance or Other Insurance (Discontinued Lines) segments since the Company does not manage its assets by underwriting segment. The Company does not allocate capital expenditures for long-lived assets to any of its underwriting segments for management reporting purposes.

The Company's Markel Ventures operations primarily consist of controlling interests in various industrial and service businesses and are viewed by management as separate and distinct from the Company's insurance operations. While each of the companies is operated independently from one another, management aggregates financial results into two industry groups: manufacturing and non-manufacturing.

On April 24, 2015, the Company completed a novation that transferred its obligations under a reinsurance contract for life and annuity benefit policies to a third party in exchange for cash payments totaling $29.0 million, net of commissions. At the time of the transaction, reserves for life and annuity benefits on the novated reinsurance contract totaled $32.6 million, resulting in a gain of $3.6 million that was recorded as an offset to other expenses.

8. Reinsurance

The following tables summarize the effect of reinsurance and retrocessional reinsurance on premiums written and earned.

Net premiums	$	2,069,774		$	1,901,207		$	2,223,642		$	1,914,974

The percentage of ceded earned premiums to gross earned premiums was 19% for the quarters and six months ended June 30, 2015 and 2014. The percentage of assumed earned premiums to net earned premiums was 32% and 35%, respectively for the quarters ended June 30, 2015 and 2014 and 32% and 36%, respectively, for the six months ended June 30, 2015 and 2014.

Incurred losses and loss adjustment expenses were net of reinsurance recoverables (ceded incurred losses and loss adjustment expenses) of $143.3 million and $141.3 million, respectively, for the quarters ended June 30, 2015 and 2014 and $232.1 million and $238.9 million, respectively, for the six months ended June 30, 2015 and 2014.

Table of Contents

On March 9, 2015, the Company completed a retrospective reinsurance transaction to cede a portfolio of policies comprised of liabilities arising from asbestos and environmental exposures that originated before 1992 in exchange for payments totaling $89.0 million, which included cash paid at closing of $69.9 million. At the time of the transaction, reserves for unpaid losses and loss adjustment expenses on the policies ceded totaled $94.1 million, resulting in a deferred gain of $5.1 million which will be recognized in earnings in future periods in proportion to actual reinsurance recoveries received pursuant to the transaction. The ceded reserves represented approximately 35% of our net asbestos and environmental reserves for losses and loss adjustment expenses as of December 31, 2014.

9. Income Taxes

The effective tax rate was 16% and 24% for the six months ended June 30, 2015 and 2014, respectively. For the six months ended June 30, 2015, the effective tax rate differs from the U.S. statutory tax rate of 35% primarily as a result of tax-exempt investment income and foreign tax credits for foreign taxes paid. In previous periods, foreign taxes paid were not available for use as tax credits against the Company's U.S. provision for income taxes. Based on the Company's estimated earnings from foreign operations in 2015, the Company expects that significant foreign taxes paid, both in the current period and prior periods, will be available for use as credits against its U.S. provision for income taxes in 2015. These projected tax credits will expire in 2025. For the six months ended June 30, 2014, the effective tax rate differs from the U.S. statutory tax rate of 35% primarily as a result of tax-exempt investment income. The decrease in the effective tax rate in 2015 compared to 2014 was primarily due to the impact of the foreign tax credits described above. This decrease was partially offset by the impact of anticipating a smaller tax benefit related to tax-exempt investment income, which resulted from having higher estimated income before income taxes in 2015 compared to 2014.

The effective tax rate for the quarter ended June 30, 2015 was 8%. The difference in the effective tax rate for the quarter ended June 30, 2015 compared to the effective tax rate for the six months ended June 30, 2015 is due to a decrease in the 2015 estimated annual effective tax rate as of June 30, 2015 compared to the estimated annual effective tax rate as of March 31, 2015. The decrease in the estimated annual effective tax rate as of June 30, 2015 compared to that estimated as of March 31, 2015 was primarily due to a decrease in the Company's estimate of projected foreign income that is subject to U.S. tax for 2015.

10. Net Income per Share

Net income per share was determined by dividing adjusted net income to shareholders by the applicable weighted average shares outstanding. Diluted net income per share is computed by dividing adjusted net income to shareholders by the weighted average number of common shares and dilutive potential common shares outstanding during the period.

12. Contingencies

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.

Table of Contents

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. generally accepted accounting principles (U.S. GAAP) and include the accounts of Markel Corporation and its subsidiaries (the Company).

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 critical accounting estimates and assumptions quarterly: evaluating the adequacy of reserves for unpaid losses and loss adjustment expenses, 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 estimates and assumptions for 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 2014 Annual Report on Form 10-K for a more complete description of our critical accounting estimates.

We also own interests in various industrial and service businesses that operate outside of the specialty insurance marketplace. Our financial goals are to earn consistent underwriting and operating profits and superior investment returns to build shareholder value.

We monitor and report our ongoing underwriting operations in the following three segments: U.S. Insurance, International Insurance and Reinsurance. In determining how to aggregate and monitor our underwriting results, management considers many factors, including the geographic location and regulatory environment of the insurance entity underwriting the risk, the nature of the insurance product sold, the type of account written and the type of customer served. The U.S. Insurance segment includes all direct business and facultative placements written by our insurance subsidiaries domiciled in the United States. The International Insurance segment includes all direct business and facultative placements written by our insurance subsidiaries domiciled outside of the United States, including our syndicate at Lloyd's of London (Lloyd's). The Reinsurance segment includes all treaty reinsurance written across the Company. Results for lines of business discontinued prior to, or in conjunction with, acquisitions are reported in the Other Insurance (Discontinued Lines) segment. All investing activities related to our insurance operations are included in the Investing segment.

Our U.S. 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. The following products are included in this segment: catastrophe-exposed property, professional liability, products liability, general liability, commercial umbrella, marine, workers' compensation, classic automobiles, specialty program insurance for well-defined niche markets, personal property and liability coverages and other coverages tailored for unique exposures. Business in this segment is written through our Wholesale, Specialty and Global Insurance divisions. The Wholesale division writes commercial risks, primarily on an excess and surplus lines basis, using a network of wholesale brokers managed on a regional basis. The Specialty division writes program insurance and other specialty coverages for well-defined niche markets, primarily on an admitted basis. The Global Insurance division writes risks outside of the standard market on both an admitted and non-admitted basis. Global Insurance division business written by our U.S. insurance subsidiaries is included in this segment.

Table of Contents

Our International Insurance segment writes risks that are characterized by either the unique nature of the exposure or the high limits of insurance coverage required by the insured. Risks written in the International Insurance segment are written on either a direct basis or a subscription basis, the latter of which means that 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. Products offered within our International Insurance segment include primary and excess of loss property, casualty, excess liability, professional liability, equine, marine, energy and trade credit insurance. Business included in this segment is produced through our Markel International and Global Insurance divisions. The Markel International division writes business worldwide from our London-based platform, which includes our syndicate at Lloyd's. Global Insurance division business written by our non-U.S. insurance subsidiaries, which primarily targets Fortune 1000 accounts, is included in this 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 catastrophe-exposed property), general casualty, credit, surety, workers' compensation, professional liability, and marine and energy. Our reinsurance product offerings are underwritten by our Global Reinsurance division and our Markel International division.

For purposes of segment reporting, the Other Insurance (Discontinued Lines) segment includes lines of business that have been discontinued prior to, or in conjunction with, acquisitions. The lines were discontinued because we believed some aspect of the product, such as risk profile or competitive environment, would not allow us to earn consistent underwriting profits. The Other Insurance (Discontinued Lines) segment also includes development on asbestos and environmental (A&E) loss reserves and the results attributable to the run-off of our life and annuity reinsurance business.

Through our wholly-owned subsidiary Markel Ventures, Inc. (Markel Ventures), we own interests in various industrial and service businesses that operate outside of the specialty insurance marketplace. These businesses are viewed by management as separate and distinct from our insurance operations and are comprised of a diverse portfolio of companies from different industries, including manufacturing, healthcare, consumer and business and financial services. Local management teams oversee the day-to-day operations of these companies, while strategic decisions are made in conjunction with members of our executive management team, principally our President and Chief Investment Officer. While each of these companies is operated independently, we aggregate their financial results into two industry groups: manufacturing and non-manufacturing. Our strategy in making these investments is similar to our strategy for purchasing equity securities. We seek to invest in profitable companies, with honest and talented management, that exhibit reinvestment opportunities and capital discipline, at reasonable prices. We intend to own the businesses acquired for a long period of time.

In July 2014, we acquired 100% of the outstanding shares of Cottrell, Inc. (Cottrell), a privately held company headquartered in Gainesville, Georgia. Cottrell is a leading manufacturer of over-the-road car hauler equipment and related car hauler parts. Results attributable to Cottrell are included with the Company's non-insurance operations, which are not included in a reportable segment.

Key Performance Indicators

We measure financial success by our ability to compound growth in 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 the most comprehensive measure of our success because it includes all underwriting, operating and investing results. We measure underwriting results by our underwriting profit or loss and combined ratio. We measure operating results from our Markel Ventures operations by earnings before interest, income taxes, depreciation and amortization (EBITDA), which is a non-GAAP financial measure, in conjunction with U.S. GAAP measures, including revenues and net income. 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 amortization resulting from purchase accounting. We measure investing results by our taxable equivalent total investment return. Our quarterly performance measures are discussed below in greater detail under "Results of Operations."

Underwriting Results

Underwriting profits are a key component of our strategy to grow book value per share. 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 as a basis for evaluating our underwriting performance.

⁽¹⁾

The U.S. GAAP combined ratio is a measure of underwriting performance and represents the relationship of incurred losses, loss adjustment expenses and underwriting, acquisition and insurance expenses to earned premiums. A combined ratio less than 100% indicates an underwriting profit, while a combined ratio greater than 100% reflects an underwriting loss. The U.S. GAAP combined ratio is the sum of the loss ratio and the expense ratio.The loss ratio represents the relationship of incurred losses and loss adjustment expenses to earned premiums. The expense ratio represents the relationship of underwriting, acquisition and insurance expenses to earned premiums.


⁽²⁾	NM – Ratio is not meaningful.

Our combined ratio was 96% and 90%, respectively for the quarter and six months ended June 30, 2015 compared to 101% and 98%, respectively, for the same periods of 2014.

For the quarter ended June 30, 2015, the decrease in the consolidated combined ratio was driven by more favorable development on prior years' loss reserves in 2015 compared to 2014, partially offset by a higher expense ratio in 2015. The increase in prior year redundancies was primarily attributable to our U.S. Insurance and International Insurance segments. Additionally, prior year losses for the quarter ended June 30, 2014 included $27.2 million of adverse development on asbestos and environmental exposures within our Other Insurance (Discontinued Lines) segment. There was no comparable adverse development during the quarter ended June 30, 2015. The increase in the expense ratio was due in part to higher profit sharing costs in 2015 compared to 2014.

For the six months ended June 30, 2015, the decrease in the consolidated combined ratio was driven by more favorable development on prior years' loss reserves in 2015 compared to 2014. The increase in prior year redundancies in 2015 was due in part to a decrease in the estimated volatility of our consolidated net reserves for unpaid losses and loss adjustment expenses as a result of ceding a significant portion of our A&E exposures to a third party during the first quarter of 2015. As a result of this decrease in estimated volatility, our level of confidence in our net reserves for unpaid losses and loss adjustment expenses increased. Therefore, management reduced prior years' loss reserves by $36.0 million, or approximately two points on the consolidated combined ratio, in order to maintain a consolidated confidence level in a range consistent with our historic levels. This reduction in prior years' loss reserves occurred in our U.S. Insurance and International Insurance segments. Prior year losses for the six months ended June 30, 2014 included $27.2 million of adverse development on asbestos and environmental exposures within our Other Insurance (Discontinued Lines) segment, with no comparable adverse development during the six months ended June 30, 2015. Also contributing to the decrease in the consolidated combined ratio for the six months ended June 30, 2015 was a lower current accident year loss ratio. The decrease in the current accident year loss ratio was due to lower attritional losses in our U.S. Insurance and Reinsurance segments in 2015 compared to 2014.

U.S. Insurance Segment

The combined ratio for the U.S. Insurance segment was 93% and 89%, respectively, for the quarter and six months ended June 30, 2015 compared to 100% and 98%, respectively, for the same periods of 2014.

For the quarter ended June 30, 2015, the decrease in the combined ratio was driven by more favorable development of prior accident years' loss reserves and a lower current accident year loss ratio.


•	The decrease in the current accident year loss ratio for the quarter ended June 30, 2015 was due to lower attritional losses compared to 2014, primarily on our inland marine and professional liability lines within the Global Insurance division.

•

The U.S. Insurance segment's combined ratio for the quarter ended June 30, 2015 included $68.6 million of favorable development on prior years' loss reserves compared to $37.9 million for the same period in 2014. Favorable development on prior years' loss reserves experienced within the U.S. Insurance segment in 2015 occurred across several product lines, but was most significant on our casualty product lines, across several accident years, and on our brokerage property line, on the 2013 and 2014 accident years. The redundancies on prior years' loss reserves during 2014 were most significant on our casualty product lines across several accident years. In 2014, favorable development on our casualty product lines was partially offset by adverse development on our architects and engineers product line, primarily on the 2008 through 2013 accident years, and on our brokerage excess and umbrella product line, primarily on the 2012 and 2013 accident years. Adverse development on these two product lines totaled $12.9 million for the quarter ended June 30, 2014.

For the six months ended June 30, 2015, the decrease in the combined ratio was due to more favorable development of prior accident years' loss reserves and a lower current accident year loss ratio.


•	The decrease in the current accident year loss ratio for the six months ended June 30, 2015 was driven by lower attritional losses within each of our divisions, across several product lines.

•

The U.S. Insurance segment's combined ratio for the six months ended June 30, 2015 included $136.2 million of favorable development on prior years' loss reserves compared to $81.4 million for the same period in 2014. The increase in loss reserve redundancies in 2015 was due in part to an increase in the confidence level of our consolidated net reserves for unpaid losses and loss adjustment expenses during the first quarter of 2015, which resulted in a $36.0 million reduction to consolidated prior years' loss reserves, of which $19.0 million was in the U.S. Insurance segment (approximately two points on the segment combined ratio). Other favorable development on prior years' loss reserves experienced within the U.S. Insurance segment during 2015 was most significant on our casualty lines, across several accident years, and on our professional liability, brokerage property and workers compensation product lines, primarily on the 2013 and 2014 accident years. In 2014, the redundancies on prior years' loss reserves were most significant on our casualty product lines across several accident years. Favorable development on our casualty product lines in 2014 was partially offset by $23.3 million of adverse development on our architects and engineers and brokerage excess and umbrella product lines.

International Insurance Segment

The combined ratio for the International Insurance segment was 98% and 86%, respectively, for the quarter and six months ended June 30, 2015 compared to 96% and 93%, respectively for the same periods of 2014.

For the quarter ended June 30, 2015, a higher current accident year loss ratio and higher expense ratio were partially offset by more favorable development on prior years' loss reserves.


•	The increase in the current accident year loss ratio was driven by large losses in our marine and energy and professional liability lines in the second quarter of 2015.

•

The International Insurance segment's combined ratio for the quarter ended June 30, 2015 included $43.4 million of favorable development on prior years' loss reserves compared to $29.6 million in 2014. For the quarter ended June 30, 2015, the favorable development on prior years' loss reserves was most significant on our marine and energy and professional liability product lines on the 2012 and 2013 accident years. The favorable development on prior years' loss reserves in 2014 was primarily within the Markel International division and was spread across several product lines, primarily on the 2011 and 2012 accident years. The increase in loss reserve redundancies in the second quarter of 2015 compared to the second quarter of 2014 was driven by more favorable development on our marine and energy and professional liability product lines within the Markel International division.


•	The increase in the expense ratio was due to higher profit sharing costs and higher general expenses in 2015 compared to 2014.

Table of Contents

For the six months ended June 30, 2015, the decrease in the combined ratio was driven by more favorable development on prior years' loss reserves, which was partially offset by a higher expense ratio.

•

The International Insurance segment's combined ratio for the six months ended June 30, 2015 included $120.0 million of favorable development on prior years' loss reserves compared to $71.9 million in 2014. The increase in loss reserve redundancies in 2015 was due in part to an increase in the confidence level of our consolidated net reserves for unpaid losses and loss adjustment expenses during the first quarter of 2015, which resulted in a $36.0 million reduction to consolidated prior years' loss reserves, of which $17.0 million was in the International Insurance segment (approximately four points on the segment combined ratio). We also experienced favorable prior year development in the Global Insurance division in 2015, compared to slightly adverse development in 2014, driven by reductions in case reserves for losses and loss adjustment expenses on a small number of large general liability and professional liability claims. For the six months ended June 30, 2015, the favorable development on prior years' loss reserves occurred across several product lines, primarily on the 2012 to 2014 accident years. Redundancies in 2015 were most significant on our marine and energy and general liability product lines. The favorable development on prior years' loss reserves in 2014 was primarily on our marine and energy, professional liability and general liability product lines within the Markel International division, on the 2010 to 2012 accident years.


•	The increase in the expense ratio was due to higher profit sharing costs and higher general expenses in 2015 compared to 2014.

Reinsurance Segment

The combined ratio for the Reinsurance segment was 100% and 94%, respectively, for the quarter and six months ended June 30, 2015 compared to 100% and 97%, respectively, for the same periods of 2014.

For the quarter ended June 30, 2015 the combined ratio was flat compared to 2014, as both the loss ratio and expense ratio in 2015 were consistent with 2014.

•

The current accident year loss ratio for the quarter ended June 30, 2015 increased slightly compared to 2014, driven by large property and energy losses in the quarter, which were partially offset by a favorable impact from changes in mix of business. During 2014, we ceased writing auto reinsurance in the United Kingdom. This product line generally carries a higher loss ratio than the rest of the segment. Our property business, which generally carries a lower loss ratio than the rest of the segment, comprised a larger portion of the segment in 2015 compared to 2014.

•

The Reinsurance segment's combined ratio for the quarter ended June 30, 2015 included $15.1 million of favorable development on prior years' loss reserves compared to $13.4 million in 2014. The favorable development on prior years' loss reserves in 2015 was most significant on our casualty and short-tail property lines of business, on the 2013 and 2014 accident years. For financial reporting purposes, development on pre-acquisition accident years' loss reserves attributable to business previously written by Alterra Capital Holdings Limited (Alterra) is included in the 2013 accident year. The favorable development on prior years' loss reserves in 2014 was primarily on our property lines on the 2012 and 2013 accident years.

For the six months ended June 30, 2015, the decrease in the combined ratio was driven by a lower current accident year loss ratio.


•	The decrease in the current accident year loss ratio for the six months ended June 30, 2015 was driven by lower property losses in 2015 compared to 2014.

•

The Reinsurance segment's combined ratio for the six months ended June 30, 2015 included $41.5 million of favorable development on prior years' loss reserves compared to $41.6 million in 2014. The favorable development on prior years' loss reserves in 2015 was most significant on our casualty and short-tail property lines of business, on the 2013 and 2014 accident years. The favorable development on prior years' loss reserves in 2014 was primarily on our property lines on the 2012 and 2013 accident years.

Other Insurance (Discontinued Lines)

The Other Insurance (Discontinued Lines) segment produced an underwriting profit of $1.6 million and an underwriting loss of $1.4 million for the quarter and six months ended June 30, 2015, respectively, compared to an underwriting loss of $21.3 million and $27.8 million, respectively, for the same periods of 2014.

The underwriting loss for both the quarter and six months ended June 30, 2014 included $27.2 million of adverse loss reserve development on A&E exposures as a result of our annual review of these exposures. We complete an annual review of A&E exposures during the third quarter of the year unless circumstances suggest an earlier review is appropriate. During 2014, based on recent activity on a small number of claims, we accelerated our annual review to the second quarter. During our 2014 review, we increased our expectation of the severity of the outcome of certain claims subject to litigation. As the ultimate

Table of Contents

outcome of known claims increases, our expected ultimate closure value on unreported claims also increases. As a result of these developments, we increased prior years' loss reserves accordingly. For the quarter ended June 30, 2014, adverse development on A&E exposures was partially offset by favorable movements in prior years loss reserves and allowances for reinsurance bad debt related to discontinued lines of business originally written by our Markel International division. Our 2015 review of A&E exposures will be performed during the third quarter.

Premiums and Net Retentions

We monitor the effect of movements in foreign currency exchange rates on gross premium volume and earned premiums. To the extent there are significant variations in foreign currency exchange rates between the U.S. dollar and the foreign currencies in which our insurance business is transacted, management uses the change in gross premium volume and earned premiums at a constant rate of exchange to evaluate trends in premium volume. The impact of foreign currency translation is excluded, when significant, as the effect of fluctuations in exchange rates could distort the analysis of trends. When excluding the effect of foreign currency translation on changes in premium, management uses the current period average exchange rates to translate both the current period and the prior period foreign currency denominated gross premiums written and earned premiums.

The following tables summarize gross premium volume, net written premiums and earned premiums by segment.



Gross Premium Volume
	Quarter Ended June 30,					Six Months Ended June 30,
(dollars in thousands)	2015		2014			2015		2014
U.S. Insurance	$	668,853	$	681,371		$	1,254,218	$	1,256,604
International Insurance	338,159		359,120			627,386		653,356
Reinsurance	258,745		302,950			636,582		792,911

Total	$	1,265,786	$	1,343,378		$	2,518,259	$	2,703,135

Gross premium volume for the quarter and six months ended June 30, 2015 decreased 6% and 7%, respectively, compared to the same periods of 2014. At a constant rate of exchange, gross premium volume for the quarter and six months ended June 30, 2015 would have decreased 4% and 5%, respectively, compared to the same periods of 2014. In both periods, the decrease was primarily attributable to lower gross premium volume in the Reinsurance segment. For the quarter ended June 30, 2015, the decrease in gross premium volume in the Reinsurance segment compared to the same period of 2014 was due in part to lower gross premium volume in our property product lines. For the six months ended June 30, 2015, the decrease in gross premium volume compared to 2014 was largely due to changes in our auto reinsurance book. During 2014, we ceased writing auto reinsurance in the United Kingdom. Additionally, we decreased our quota share percentage on our non-standard auto reinsurance business. Gross premium volume in our International Insurance segment decreased 6% and 4% for the quarter and six months ended June 30, 2015, respectively, compared to the same periods of 2014, primarily driven by the impact of changes in foreign currency exchange rates. At a constant rate of exchange, gross premium volume in the International Insurance segment would have decreased 1% for the quarter ended June 30, 2015 and increased 1% for the six months ended June 30, 2015, compared to the same periods of 2014.

We have continued to see small price increases across many of our product lines during 2015. However, beginning in 2014 and continuing into 2015, we have experienced softening prices across most of our property product lines, as well as on our marine and energy lines. Our large account business is also subject to more pricing pressure. When we believe the prevailing market price will not support our underwriting profit targets, the business is not written. As a result of our underwriting discipline, gross premium volume may vary when we alter our product offerings to maintain or improve underwriting profitability.

Net retention of gross premium volume for both the quarter and six months ended June 30, 2015 was 82% compared to 81% and 82%, respectively, for the same periods of 2014. The increase in net retention for the quarter ended June 30, 2015 compared to the same period of 2014 was driven by higher retention within the International segment. The professional liability and general liability product lines within the Markel International division carry higher retention rates than the rest of the International Insurance segment and comprised a larger portion of the segment in 2015 compared to 2014. For the six month period ended June 30, 2015, the impact of higher retentions in our International Insurance segment was offset by lower retentions on our property product lines within the Reinsurance segment, which comprised a larger portion of our premium volume in the Reinsurance segment in 2015 compared to 2014. We purchase reinsurance and retrocessional reinsurance in order to manage our net retention on individual risks and enable us to write policies with sufficient limits to meet policyholder needs.

Total	$	957,557	$	965,599	$	1,901,207	$	1,914,974

Earned premiums for the quarter and six months ended June 30, 2015 decreased 1% compared to the same periods of 2014. The decrease in earned premiums for the quarter and six months ended June 30, 2015 was driven by the effects of foreign currency exchange rate movements in our International Insurance and Reinsurance segments, which more than offset higher earned premiums in the U.S. Insurance segment. Lower earned premiums in the Reinsurance segment were also due to lower gross premium volume. The increase in earned premiums in our U.S. Insurance segment for the quarter and six months ended June 30, 2015 was primarily due to higher earned premiums on various product lines within our Specialty division compared to the same periods of 2014. At a constant rate of exchange, consolidated earned premiums for both the quarter and six months ended June 30, 2015 would have increased 2% compared to the same periods of 2014.

We evaluate our investment performance by analyzing taxable equivalent total investment return. Taxable equivalent total investment return includes items that impact net income, such as coupon interest on fixed maturities, dividends on equity securities and realized investment gains or losses, as well as changes in unrealized gains or losses, 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 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 decrease in net investment income for the quarter ended June 30, 2015 was driven by lower bond income on our fixed maturity portfolio due to lower bond holdings compared to the same period of 2014. This decrease was partially offset by increased dividend income on our equity portfolio due to higher equity security holdings in 2015 compared to 2014. The increase in net investment income for the six months ended June 30, 2015 was primarily attributable to increased dividend income on our equity portfolio due to higher equity security holdings in 2015 compared to 2014. See note 3(d) of the notes to consolidated financial statements for details regarding the components of net investment income. There were no write downs for other-than-temporary declines in the estimated fair value of investments for the quarter ended June 30, 2015. Net realized investment gains for the second quarter of 2014 included $1.0 million of write downs for other-than-temporary declines in the estimated fair value of investments. Net realized investment gains for the six months ended June 30, 2015 included $5.1 million of write downs for other-than-temporary declines in the estimated fair value of investments compared to $1.0 million for the same period of 2014.

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 June 30, 2015, we held securities with gross unrealized losses of $63.8 million, or less than 1% of invested assets. All 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 June 30, 2015. However, given the volatility in the debt and equity markets, 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.

Other Revenues and Other Expenses

Markel Ventures Operations

Operating revenues and expenses associated with our Markel Ventures operations are included in other revenues and other expenses in the consolidated statements of income and comprehensive income (loss). We consolidate our Markel Ventures operations on a one-month lag. The following table summarizes the operating revenues, net income (loss) to shareholders and EBITDA from our Markel Ventures operations.



	Quarter Ended June 30,					Six Months Ended June 30,
(dollars in thousands)	2015			2014		2015		2014
Operating revenues	$	239,553		$	183,642	$	484,996	$	354,848
Net income (loss) to shareholders	$	(2,554	)	$	4,077	$	7,956	$	5,144
EBITDA	$	13,180		$	20,946	$	46,769	$	35,057

Revenues from our Markel Ventures operations increased $55.9 million and $130.1 million for the quarter and six months ended June 30, 2015 compared to the same periods of 2014. For the quarter ended June 30, 2015, the increase in revenues was primarily driven by our acquisition of Cottrell in July 2014, partially offset by lower sales volume in certain of our other manufacturing operations compared to the same period of 2014. For the six months ended June 30, 2015, the increase in revenues is primarily attributable to the acquisition of Cottrell and higher revenues within our other manufacturing operations, due in part to higher sales volume in 2015 compared to 2014. Revenues for the six months ended June 30, 2015 also reflected growth in certain of our non-manufacturing operations, which was partially offset by the impact of slower activity in our residential home sales in 2015 compared to 2014.

Net income (loss) to shareholders and EBITDA from our Markel Ventures operations decreased for the quarter ended June 30, 2015 compared to the same period of 2014 primarily due to an increase in our estimate of the contingent consideration obligation related to the acquisition of Cottrell, partially offset by the contribution of earnings attributable to Cottrell in 2015. A portion of the purchase consideration for Cottrell is based on Cottrell's post-acquisition earnings through 2015, as defined in the purchase agreement, which we now expect will exceed our initial projection. As a result, our estimate of the fair value of the contingent consideration increased by $17.6 million during the second quarter of 2015. As of June 30, 2015, the fair value of our outstanding contingent consideration obligation was $31.1 million, which we expect to pay in 2016. While this obligation is subject to further changes based on Cottrell's actual results through December 31, 2015, we do not believe the impact of such an adjustment would be material to our results of operations or cash flows. Net income to shareholders and EBITDA from our Markel Ventures operations increased for the six months ended June 30, 2015 compared to the same period of 2014 primarily due to our acquisition of Cottrell and more favorable results within certain of our manufacturing operations, partially offset by the increase in our contingent consideration obligation related to the acquisition of Cottrell.

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 revenues and net income (loss), to monitor and evaluate the performance of our Markel Ventures operations. 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 amortization resulting from purchase accounting. The following table reconciles EBITDA of Markel Ventures, net of noncontrolling interests, to consolidated net income to shareholders.

⁽¹⁾	Interest expense for the quarters ended June 30, 2015 and 2014 includes intercompany interest expense of $2.5 million and $1.6 million, respectively. Interest expense for the six months ended June 30, 2015 and 2014 includes intercompany interest expense of $5.1 million and $3.2 million, respectively.

Life and Annuity Benefits

The Other Insurance (Discontinued Lines) segment for the quarter ended June 30, 2015 included other revenues of $0.4 million and other expenses of $3.3 million, compared to other revenues of $0.1 million and other expenses of $8.7 million for the same period of 2014. The Other Insurance (Discontinued Lines) segment for the six months ended June 30, 2015 included other revenues of $0.3 million and other expenses of $10.7 million, compared to other revenues of $0.2 million and other expenses of $17.3 million for the same period of 2014. The other revenues and other expenses included in the Other Insurance (Discontinued Lines) segment are related to the run-off of our life and annuity reinsurance business. The life and annuity benefit reserves were acquired as part of our acquisition of Alterra and are recorded on a discounted present value basis using assumptions that were determined as of May 1, 2013. The accretion of this discount is recognized in the statement of income and comprehensive income (loss) as other expenses. Invested assets and the related investment income that support the life and annuity reinsurance contracts are reported in the Investing segment. As a result, we expect the results reported in the Other Insurance (Discontinued Lines) segment attributable to our life and annuity business will continue to reflect losses in future periods due to the accretion of the discount on the life and annuity benefit reserves, which are forecasted to pay out over the next 40 to 50 years. Other revenues attributable to the life and annuity business included in the Other Insurance (Discontinued Lines) segment represent ongoing premium adjustments on existing contracts.

On April 24, 2015, we completed a novation that transferred our obligations under a reinsurance contract for life and annuity benefit policies to a third party in exchange for cash payments totaling $29.0 million, net of commissions. At the time of the transaction, reserves for life and annuity benefits on the novated reinsurance contract totaled $32.6 million, resulting in a gain of $3.6 million that was recorded as an offset to other expenses.

Interest Expense and Income Taxes

Interest expense for the quarter and six months ended June 30, 2015 was $29.3 million and $58.6 million, respectively, which is comparable to the quarter and six months ended June 30, 2014 with $29.8 million and $59.5 million of interest expense, respectively.

The effective tax rate was 16% and 24% for the six months ended June 30, 2015 and 2014, respectively. For the six months ended June 30, 2015, the effective tax rate differs from the U.S. statutory tax rate of 35% primarily as a result of tax-exempt investment income and foreign tax credits for foreign taxes paid. In previous periods, foreign taxes paid were not available for use as tax credits against our U.S. provision for income taxes and may not be available in future periods. Based on our estimated earnings from our foreign operations in 2015, we expect that significant foreign taxes paid, both in the current period and prior periods, will be available for use as credits against our U.S. provision for income taxes in 2015. Our anticipated recognition of these tax credits in 2015 has a favorable impact on our 2015 effective tax rate of approximately 12%. We caution readers that a similar benefit may not be recognizable in future years. For the six months ended June 30, 2014, the effective tax rate differs from the U.S. statutory tax rate of 35% primarily as a result of tax-exempt investment income. The decrease in the effective tax rate in 2015 compared to 2014 was primarily due to the impact of the foreign tax credits described above. This decrease was partially offset by the impact of anticipating a smaller tax benefit related to tax-exempt investment income, which resulted from having higher estimated income before income taxes in 2015 compared to 2014.

Table of Contents

The effective tax rate for the quarter ended June 30, 2015 was 8%. The difference in the effective tax rate for the quarter ended June 30, 2015 compared to the effective tax rate for the six months ended June 30, 2015 is due to a decrease in the 2015 estimated annual effective tax rate as of June 30, 2015 compared to the estimated annual effective tax rate as of March 31, 2015. The decrease in the estimated annual effective tax rate as of June 30, 2015 compared to the estimate as of March 31, 2015 was primarily due to a decrease in our estimate of projected foreign income that is subject to U.S. tax for 2015.

Our effective tax rate, which is based upon the expected annual effective tax rate, may fluctuate from period to period based on the relative mix of income or loss reported by jurisdiction and the varying tax rates in each jurisdiction.

Comprehensive Income (Loss) to Shareholders

Comprehensive loss to shareholders was $132.9 million for the second quarter of 2015 compared to comprehensive income to shareholders of $250.6 million for the same period of 2014. Comprehensive loss to shareholders for the second quarter of 2015 included net income to shareholders of $91.4 million, a decrease in net unrealized gains on investments, net of taxes, of $235.2 million and an increase in foreign currency translation adjustments, net of taxes, of $10.4 million. Comprehensive income to shareholders for the second quarter of 2014 included an increase in net unrealized gains on investments, net of taxes, of $203.5 million and net income to shareholders of $40.1 million.

Comprehensive income to shareholders was $148.9 million for the six months ended June 30, 2015 compared to $480.9 million for the same period of 2014. Comprehensive income to shareholders for the six months ended June 30, 2015 included net income to shareholders of $282.4 million, a decrease in net unrealized gains on investments, net of taxes, of $123.0 million and a decrease in foreign currency translation adjustments, net of taxes, of $11.4 million. Comprehensive income to shareholders for the six months ended June 30, 2014 included an increase in net unrealized gains on investments, net of taxes, of $344.9 million and net income to shareholders of $127.8 million.

The decrease in net unrealized gains on investments, net of taxes, for both the quarter and six months ended June 30, 2015 was attributable to a decrease in the fair value of our fixed maturity portfolio as of June 30, 2015 compared to March 31, 2015 and December 31, 2014, respectively. The quarter ended June 30, 2015 also reflected the impact of a decline in the fair value of our equity portfolio.

The increase in net unrealized gains on investments, net of taxes, for both the quarter and six months ended June 30, 2014 was attributable to an increase in the fair value of both our fixed maturity and equity portfolios as of June 30, 2014 compared to March 31, 2014 and December 31, 2013, respectively.

Financial Condition

Investments, cash and cash equivalents and restricted cash and cash equivalents (invested assets) were $18.5 billion at June 30, 2015 compared to $18.6 billion at December 31, 2014. Net unrealized gains on investments, net of taxes, were $1.7 billion at June 30, 2015 compared to $1.8 billion at December 31, 2014. Equity securities were $4.4 billion, or 24% of invested assets, at June 30, 2015 compared to $4.1 billion, or 22% of invested assets, at December 31, 2014.

Net cash provided by operating activities was $238.0 million for the six months ended June 30, 2015 compared to $237.1 million for the same period of 2014. Net cash provided by operating activities for the six months ended June 30, 2015 included higher cash flows attributable to our Markel Ventures operations and lower payments for income taxes compared to the same period of 2014. Net cash provided by operating activities for the six months ended June 30, 2015 was net of a $29.0 million cash payment made to transfer our obligations under a reinsurance contract for life and annuity benefits to a third party. Net cash provided by operating activities for the six months ended June 30, 2015 was also net of a $69.9 million cash payment made in connection with a retrospective reinsurance transaction completed March 9, 2015, in which we ceded a portfolio of policies comprised of liabilities arising from A&E exposures that originated before 1992 to a third party. At the time of the transaction, reserves for unpaid losses and loss adjustment expenses on the policies ceded totaled $94.1 million. The net loss reserves underlying this transaction are expected to be formally transferred to the third party in 2015 by way of a Part VII transfer pursuant to the Financial Services and Markets Act 2000 of the United Kingdom. Due to the unique aspects of A&E exposures, the ultimate estimated value of loss reserves is subject to greater uncertainty than other types of claims. Although we believe our loss reserves for these A&E exposures were adequate, this transaction eliminates the uncertainty regarding the potential for adverse development of estimated ultimate liabilities on the underlying policies. While we recognize that the use of funds for this transaction results in lower investment income in the short term, eliminating these exposures provides us with additional flexibility to allocate capital from our insurance operations to our holding company, where we believe we may have opportunities to invest capital at a higher rate of return.

Table of Contents

Net cash used by investing activities was $288.3 million for the six months ended June 30, 2015 compared to $243.5 million for the same period of 2014. Due to the low interest rate environment, during 2015, we continued to purchase equity securities and limit our allocation of funds for purchases of fixed maturities. We also allocated more cash and cash equivalents to short-term investments to maintain adequate liquidity and diversification. Cash flow from investing activities is affected by various factors such as anticipated payment of claims, financing activity, acquisition opportunities and individual buy and sell decisions made in the normal course of our investment portfolio management.

Net cash used by financing activities was $48.3 million for the six months ended June 30, 2015 compared to $38.8 million for the same period of 2014. Cash of $22.7 million and $17.4 million was used to repurchase shares of our common stock during the first six months of 2015 and 2014, respectively.

We seek to maintain prudent levels of liquidity and financial leverage for the protection of our policyholders, creditors and shareholders. Our target capital structure includes approximately 30% debt. Our debt to capital ratio was 22% at June 30, 2015 and 23% at December 31, 2014. From time to time, our debt to capital ratio may increase due to business opportunities that may be financed in the short term with debt. Alternatively, our debt to capital ratio may fall below our target capital structure, which provides us with additional borrowing capacity to respond when future opportunities arise.

We have access to various capital sources, including dividends from certain of our insurance subsidiaries, holding company invested assets, undrawn capacity under our revolving and secured credit facilities and access to the debt and equity capital markets. We believe that we have sufficient liquidity to meet our capital needs.

On May 19, 2015, we reduced the capacity of our $650 million secured credit facility, which expires in December 2015, to $550 million. We do not intend to renew this secured credit facility when it expires, however, we believe the capacity of our other credit facilities is sufficient to meet our needs.

Our holding company had $1.4 billion and $1.5 billion of invested assets at June 30, 2015 and December 31, 2014, respectively.

Shareholders' equity was $7.7 billion at June 30, 2015 and $7.6 billion at December 31, 2014. Book value per share increased to $554.97 at June 30, 2015 from $543.96 at December 31, 2014 primarily due to $148.9 million of comprehensive income to shareholders for the six months ended June 30, 2015.

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 within our Markel Ventures operations are subject to commodity risk; however, this risk is not material to the Company.

As of June 30, 2015, the carrying value of goodwill and intangible assets denominated in a foreign currency, which is not matched or hedged, was $252.4 million, compared to $262.9 million as of December 31, 2014. The decrease is primarily due to the impact of the strengthening of the U.S. dollar against the Canadian dollar and the euro during the first quarter of 2015. During the six months ended June 30, 2015, 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, 2014.

Credit risk is the potential loss resulting from adverse changes in an issuer's ability to repay its debt obligations. General concern 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.

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 approximately 97% 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 June 30, 2015, 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. General concern exists about the financial difficulties facing certain European 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 six months ended June 30, 2015, there were no material changes in our foreign government fixed maturity holdings.

The estimated fair value of our investment portfolio at June 30, 2015 was $18.5 billion, 76% of which was invested in fixed maturities, short-term investments, cash and cash equivalents and restricted cash and cash equivalents and 24% of which was invested in equity securities. At December 31, 2014, the estimated fair value of our investment portfolio was $18.6 billion, 78% of which was invested in fixed maturities, short-term investments, cash and cash equivalents and restricted cash and cash equivalents and 22% of which was invested in equity securities.

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 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 Chief Executive Officer (CEO) and the Chief Financial Officer (CFO).

Our management, including the CEO and CFO, 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 CEO and CFO 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 second quarter of 2015 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 "Risk Factors" and "Safe Harbor and Cautionary Statement" in our 2014 Annual Report on Form 10-K or are included in the items listed below:


•	our anticipated premium volume is based on current knowledge and assumes 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, including demand and pricing in the insurance and reinsurance markets;


•	actions by competitors, including 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 and weather-related catastrophes) may exceed expectations, are unpredictable and, in the case of 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 (including but not limited to those uncertainties associated with our A&E reserves) 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;


•	the failure of any loss limitation methods we employ;


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


•	industry and economic conditions, deterioration in reinsurer credit quality and coverage disputes can affect the ability or willingness of reinsurers to pay balances due;


•	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;

•

economic conditions, actual or potential defaults in 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 maturities and equity securities, as well as the carrying value of our other assets and liabilities, and this impact may be heightened by market volatility;

•

a number of factors may adversely affect the markets served by our Markel Ventures operations and negatively impact their revenues and profitability, including, among others: economic conditions; changes in government support for education, healthcare and infrastructure projects; changes in capital spending levels; changes in the housing market; and volatility in interest and foreign currency exchange rates;


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


•	we have substantial investments in municipal bonds (approximately $4.0 billion at June 30, 2015) and, although less than 15% of our municipal bond portfolio is tied to any one state, widespread defaults could adversely affect our results of operations and financial condition;

•

the impacts of periods of slow economic growth; the continuing effects of government intervention into the markets to address financial downturns (including, among other things, the effects of the Dodd-Frank Wall Street Reform and Consumer Protection Act and regulations adopted thereunder); the outcome of economic and currency concerns in the Eurozone; material changes to the monetary policies of central banks, including the U.S. Federal Reserve and the European Central Bank; and the combined impact of the foregoing on our industry, business and investment portfolio;


•	the impacts that the political and civil unrest in Ukraine and related sanctions imposed on Russia by the U.S. and other Western European governments may have on our businesses and the markets they serve or that any disruption in European or worldwide economic conditions generally arising from this situation may have on our business, industry or investment portfolio;


•	the impacts that the Israeli-Palestinian conflict may have on our businesses and the markets they serve or that any disruptions in Middle Eastern or worldwide economic conditions generally arising from this conflict may have on our business, industry or investment portfolio;


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


•	the impact of the implementation of U.S. health care reform legislation and regulations under that legislation on our business;


•	our business is dependent upon the successful functioning and security of our computer systems; if our information technology systems fail or suffer a security breach, our business or reputation could be adversely impacted;


•	we have recently completed a number of acquisitions, which 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 loss of services of any executive officer or other key personnel could adversely impact our operations;


•	our expanding international operations expose us to increased investment, political and economic risks, including foreign currency exchange rate and credit risk;


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


•	adverse changes in our assigned financial strength or debt ratings could adversely impact our ability to attract and retain business or obtain capital.

Our premium volume, underwriting and investment results and results from our non-insurance operations have been and will continue to be potentially materially affected by these factors. 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.
