BUSINESS OVERVIEW

We are a diverse financial holding company serving a variety of niche markets. Our principal business markets and underwrites specialty insurance products and programs. We believe that our specialty product focus and niche market strategy enable us to develop expertise and specialized market knowledge. We seek to differentiate ourselves from competitors by our expertise, service, continuity and other value-based considerations. We compete in three segments of the specialty insurance marketplace: the Excess and Surplus Lines, the Specialty Admitted and the London markets. We also own interests in various businesses that operate outside of the specialty insurance marketplace. Our financial goals are to earn consistent underwriting and operating profits and superior investment returns to build shareholder value.

Specialty Insurance

The specialty insurance market differs significantly from the standard market. In the standard market, insurance rates and forms are highly regulated, products and coverages are largely uniform with relatively predictable exposures and companies tend to compete for customers on the basis of price. In contrast, the specialty market provides coverage for hard-to-place risks that generally do not fit the underwriting criteria of standard carriers. For example, United States insurance regulations generally require an Excess and Surplus Lines (E&S) account to be declined by admitted carriers before an E&S company may write the business. Hard-to-place risks written in the Specialty Admitted market cover insureds engaged in similar, but highly specialized activities who require a total insurance program not otherwise available from standard insurers or insurance products that are overlooked by large admitted carriers. Hard-to-place risks in the London market are generally distinguishable from standard risks due to the complexity or significant size of the risk.

Competition in the specialty insurance market tends to focus less on price than in the standard insurance market and more on other value-based considerations, such as availability, service and expertise. While specialty market exposures may have higher perceived insurance risks than their standard market counterparts, we seek to manage these risks to achieve higher financial returns. To reach our financial and operational goals, we must have extensive knowledge and expertise in our chosen markets. Many of our accounts are considered on an individual basis where customized forms and tailored solutions are employed.

By focusing on the distinctive risk characteristics of our insureds, we have been able to identify a variety of niche markets where we can add value with our specialty product offerings. Examples of niche markets that we have targeted include wind and earthquake exposed commercial properties, liability coverage for highly specialized professionals, equine-related risks, workers’ compensation insurance for small businesses, yachts and other watercraft, motorcycles and marine, energy and environmental-related activities. Our market strategy in each of these areas of specialization is tailored to the unique nature of the loss exposure, coverage and services required by insureds. In each of our niche markets, we assign teams of experienced underwriters and claims specialists who provide a full range of insurance services.

Markets

The E&S market focuses on hard-to-place risks and loss exposures that generally cannot be written in the standard market. E&S eligibility allows our insurance subsidiaries to underwrite unique loss exposures with more flexible policy forms and unregulated premium rates. This typically results in coverages that are more restrictive and more expensive than coverages in the standard market.

12  |

In 2009, the E&S market represented approximately $33 billion, or 7%, of the approximately $475 billion United States property and casualty (P&C) industry.⁽¹⁾ We are the sixth largest E&S writer in the United States as measured by direct premium writings.⁽¹⁾ In 2010, we wrote $898 million of business in our Excess and Surplus Lines segment.

We also write business in the Specialty Admitted market. Most of these risks, although unique and hard-to-place in the standard market, must remain with an admitted insurance company for marketing and regulatory reasons. The Specialty Admitted market is subject to more state regulation than the E&S market, particularly with regard to rate and form filing requirements, restrictions on the ability to exit lines of business, premium tax payments and membership in various state associations, such as state guaranty funds and assigned risk plans. In late 2010, we acquired Aspen Holdings, Inc. and began writing workers’ compensation insurance within the Specialty Admitted market. In 2010, we wrote $375 million of business in our Specialty Admitted segment.

The London market, which produced approximately $50 billion of gross written premium in 2009, is the largest insurance market in Europe and third largest in the world.⁽²⁾ The London market is known for its ability to provide innovative, tailored coverage and capacity for unique and hard-to-place risks. It is primarily a broker market, which means that insurance brokers bring most of the business to the market. The London market is also largely a subscription market, which means that loss exposures brought into the market are typically insured by more than one insurance company or Lloyd’s syndicate, often due to the high limits of insurance coverage required. We write business on both a direct and subscription basis in the London market. 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.

In 2009, gross premium written through Lloyd’s syndicates generated approximately two-thirds of the London market’s international insurance business⁽²⁾, making Lloyd’s the world’s second largest commercial surplus lines insurer⁽¹⁾ and fifth largest reinsurer.⁽³⁾ Corporate capital providers often provide a majority of a syndicate’s capacity and also often own or control the syndicate’s managing agent. This structure permits the capital provider to exert greater influence on, and demand greater accountability for, underwriting results. In 2009, corporate capital providers accounted for approximately 95% of total underwriting capacity in Lloyd’s.⁽⁴⁾

We participate in the London market through Markel International, which includes Markel Capital Limited (Markel Capital) and Markel International Insurance Company Limited (MIICL). Markel Capital is the corporate capital provider for our syndicate at Lloyd’s, Markel Syndicate 3000, which is managed by Markel Syndicate Management Limited. In 2010, we wrote $709 million of business in our London Insurance Market segment.

In 2010, 28% of consolidated premium writings related to foreign risks (i.e., coverage for risks located outside of the United States), of which 25% were from the United Kingdom and 17% were from Canada. In 2009, 26% of our premium writings related to foreign risks, of which 28% were from the United Kingdom. In 2008, 23% of our premium writings related to foreign risks, of which 32% were from the United Kingdom. In each of these years, there were no other individual foreign countries from which premium writings were material. Premium writings are attributed to individual countries based upon location of risk.

BUSINESS OVERVIEW (continued)

Competition

We compete with numerous domestic and international insurance companies and reinsurers, Lloyd’s syndicates, risk retention groups, insurance buying groups, risk securitization programs and alternative self-insurance mechanisms. Competition may take the form of lower prices, broader coverages, greater product flexibility, higher quality services or higher ratings by independent rating agencies. In all of our markets, we compete by developing specialty products to satisfy well-defined market needs and by maintaining relationships with agents, brokers and insureds who rely on our expertise. This expertise is our principal means of competing. We offer over 100 product lines. Each of these products has its own distinct competitive environment. With each of our products, we seek to compete with innovative ideas, appropriate pricing, expense control and quality service to policyholders, agents and brokers.

Few barriers exist to prevent insurers from entering our segments of the P&C industry. Market conditions and capital capacity influence the degree of competition at any point in time. Periods of intense competition, which typically include broader coverage terms, lower prices and excess underwriting capacity, are referred to as a “soft market.” A favorable insurance market is commonly referred to as a “hard market” and is characterized by stricter coverage terms, higher prices and lower underwriting capacity. During soft markets, unfavorable conditions exist due, in part, to what many perceive to be excessive amounts of capital in the industry. In an attempt to use their capital, many insurance companies seek to write additional premiums without appropriate regard for ultimate profitability, and standard insurance companies are more willing to write specialty coverages. The opposite is typically true during hard markets.

The Insurance Market Cycle

After a decade of soft market conditions, the insurance industry experienced favorable conditions beginning in late 2000, which continued through 2003 for most product lines. During 2004, the market began to soften and the industry began to show signs of increased competition. Since 2005, we have been in a soft insurance market and have experienced intense competition. During the current soft market cycle, we have experienced price deterioration in virtually all of our product areas due in part to an increased presence of standard insurance companies in our markets. During 2008, given the rapid deterioration in underwriting capacity as a result of the disruptions in the financial markets and losses from catastrophes, the rate of decline in prices began to slow. However, the effects of the economic environment contributed to further declines in gross premium volume in 2009 and 2010. Premiums for many of our product lines are based upon our insureds’ revenues, gross receipts or payroll, which have been negatively impacted by the depressed levels of business activity in recent years. In 2010, we continued to experience pricing pressure due in part to intense competition, which resulted in further price deterioration across many of our product lines, most notably our professional and products liability programs within the Excess and Surplus Lines segment. However, we experienced moderate price increases in several product lines during 2010, most notably those offered by Markel International.

We routinely review the pricing of our major product lines and have pursued price increases in many product areas; however, as a result of continued soft insurance market conditions, our targeted price increases have been met with resistance in the marketplace, particularly within the Excess and Surplus Lines segment. In general, we believe prevailing rates within the property and casualty insurance marketplace are lower than our targeted pricing levels. 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 for many of our product lines, most notably within the Excess and Surplus Lines segment, has declined and, if the competitive environment does not improve, could decline further in the future.

14  |

Underwriting Philosophy

By focusing on market niches where we have underwriting expertise, we seek to earn consistent underwriting profits. Underwriting profits are a key component of our strategy. 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. We use underwriting profit or loss as a basis for evaluating our underwriting performance.

The combined ratio is a measure of underwriting performance and represents the relationship of incurred losses, loss adjustment expenses and underwriting, acquisition and insurance expenses to earned premiums. A combined ratio less than 100% indicates an underwriting profit, while a combined ratio greater than 100% reflects an underwriting loss. In 2010, our combined ratio was 97%. See Management’s Discussion & Analysis of Financial Condition and Results of Operations for further discussion of our underwriting results.

The following graph compares our combined ratio to the P&C industry’s combined ratio for the past five years.

Underwriting Segments

We define our underwriting segments based on the areas of the specialty insurance market in which we compete, the Excess and Surplus Lines, Specialty Admitted and London markets. See note 17 of the notes to consolidated financial statements for additional segment reporting disclosures.

For purposes of segment reporting, our Other Insurance (Discontinued Lines) segment includes lines of business that have been discontinued in conjunction with the acquisitions of insurance operations. 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 product line leadership group is under the direction of our Chief Underwriting Officer, who also is ultimately responsible for the underwriting activities of our Specialty Admitted and London Insurance Market segments.

BUSINESS OVERVIEW (continued)

Markel Specialty. The Markel Specialty unit focuses on providing total insurance programs for businesses engaged in highly specialized activities. These activities typically do not fit the risk profiles of standard insurers and make complete coverage difficult to obtain from a single insurer.

The Markel Specialty unit is organized into product areas that concentrate on particular markets and customer groups. The property and casualty division writes commercial coverages for youth and recreation oriented organizations, such as children’s camps, conference centers, YMCAs, YWCAs, Boys and Girls Clubs, child care centers, nursery schools, private and Montessori schools and gymnastics, martial arts and dance schools. This division also writes commercial coverages for social service organizations, museums and historic homes, performing arts organizations, bed and breakfast inns, outfitters and guides, hunting and fishing lodges, dude ranches and rod and gun clubs. The horse and farm operations specialize in insurance coverages for equine-related risks, such as horse mortality, theft, infertility, transit and specified perils. We also provide property and liability coverages for farms and boarding, breeding and training facilities. The accident and health division writes liability and accident insurance for amateur sports organizations, accident and medical insurance for colleges, universities, public schools and private schools, monoline accident and medical coverage for various niche markets, short-term medical insurance, pet health insurance, stop-loss insurance for self-insured medical plans and medical excess reinsurance coverage. The garage division provides commercial coverages for auto repair garages, gas stations and convenience stores and used car dealers. The general agent programs division develops partnerships with managing general agents to offer single source admitted and non-admitted programs for a specific class or line of business.

The Markel Risk Solutions facility works with select retail producers on a national basis to provide admitted market solutions to accounts having difficulty finding coverage in the standard marketplace. Accounts of various classes and sizes are written with emphasis placed on individual risk underwriting and pricing.

The majority of Markel Specialty business is produced by retail insurance agents. Management grants very limited underwriting authority to a few carefully selected agents and controls agency business through regular audits and pre-approvals. Certain products and programs are also marketed directly to consumers or through wholesale producers. Markel Specialty business is primarily written on Markel Insurance Company (MIC). MIC is domiciled in Illinois and is licensed to write P&C insurance in all 50 states and the District of Columbia.

FirstComp. On October 15, 2010, we completed our acquisition of Aspen Holdings, Inc., a Nebraska-based privately held corporation whose FirstComp insurance group provides workers’ compensation insurance and related services, principally to small businesses, in 31 states. The majority of FirstComp business is produced by retail insurance agents. FirstComp business produced for our benefit is written on FirstComp Insurance Company, which is domiciled in Nebraska, or MIC. FirstComp also produces business for unaffiliated insurance companies through FirstComp Underwriters Group, Inc. and FirstComp Insurance Agency, Inc., which act as managing general agents. FirstComp has distribution relationships with more than 8,000 independent insurance agencies. These agencies are generally located in small towns and have been underserved by other market participants because of their size. For expense efficiency reasons, carriers often will not do business with agencies that do not have large books of business. Utilizing its proprietary technology platform, FirstComp is able to service these small agencies in a cost-efficient manner.

The FirstComp operations collectively produced approximately $290 million of gross written premiums in 2010. During 2010, the Specialty Admitted segment included $40.7 million of gross premium volume produced by FirstComp.

The Non-Marine Property division writes property and liability business for a wide range of insureds, providing coverage ranging from fire to catastrophe perils such as earthquake and windstorm. Business is written in either the open market or delegated authority accounts. The open market account writes direct and facultative risks, typically for Fortune 1000 companies. Open market business is written mainly on a worldwide basis by our underwriters to London brokers, with each risk being considered on its own merits. The delegated authority account focuses mainly on small commercial insureds and is written through a network of coverholders. The delegated authority account is primarily written in the United States. Coverholders underwriting this business are closely monitored, subject to audit and must adhere to strict underwriting guidelines.

The Professional and Financial Risks division underwrites professional indemnity, directors’ and officers’ liability, intellectual property, some miscellaneous defense costs, incidental commercial crime and general liability coverages. The professional indemnity account offers unique solutions in four main professional classes including miscellaneous professionals and consultants, construction professionals, financial service professionals and professional practices. The miscellaneous professionals and consultants class includes coverages for a wide range of professionals including management consultants, publishers, broadcasters, pension trustees and public officials. The construction class includes coverages for surveyors, engineers, architects and estate agents. The financial services class includes coverages for insurance brokers, insurance agents, financial consultants, stockbrokers, fund managers, venture capitalists and bankers. The professional practices class includes coverages for accountants and solicitors. The directors’ and officers’ liability account offers coverage to public, private and non-profit companies of all sizes on either an individual or blanket basis. The Professional and Financial Risks division writes business on a worldwide basis, limiting exposure in the United States.

The Retail division offers a full range of professional liability products, including professional indemnity, directors’ and officers’ liability and employment practices liability, through six branch offices in England and one branch office in Scotland. In addition, coverage is provided for small to

medium-sized commercial property risks on both a stand-alone and package basis. The branch offices provide insureds and brokers with direct access to decision-making underwriters who possess specialized knowledge of their local markets. The division also underwrites certain niche liability products such as coverages for social welfare organizations.

The Specialty division provides property treaty reinsurance on an excess of loss and proportional basis for per risk and catastrophe exposures. A significant portion of the division’s excess of loss catastrophe and per risk treaty business comes from the United States with the remainder coming from international property treaties. The Specialty division also offers direct coverage for a number of specialist classes including financial institutions, contingency and other special risks. Coverage includes bankers blanket bond, computer crime, commercial fidelity, professional sports liability, event cancellation, non-appearance and prize indemnity.

The Equine division writes bloodstock, livestock and aquaculture-related products on a worldwide basis. The bloodstock account provides coverage for risks of mortality, theft, infertility and specified perils for insureds ranging in size from large stud farms to private horse owners. The livestock account provides coverage for farms, zoos, animal theme parks and safari parks. The aquaculture account provides comprehensive coverage for fish at onshore farms, offshore farms and in-transit risks.

The Trade Credit division writes short-term trade credit coverage for commercial risks, including insolvency and protracted default. Political risks are covered in conjunction with commercial risks for currency inconvertibility, government action, import/export license cancellation, public buyer default and war. Products include coverages for captive reinsurance, trade receivables securitization, vendor financing, pre-credit/work in progress, anticipatory credit, factoring and contract replacement. Policy structures are on an excess of loss basis or ground up for specific or named buyer risks.

ESR underwrites a diverse portfolio of property and casualty coverages for Canadian domiciled insureds. ESR provides primary general liability, products liability, excess and umbrella, environmental liability and property coverages. ESR also writes professional indemnity, directors and officers and equine products.

Reinsurance

We purchase reinsurance in order to reduce our retention on individual risks and to have the ability to underwrite policies with sufficient limits to meet policyholder needs. As part of our underwriting philosophy, we seek to offer products with limits that do not require significant amounts of reinsurance. We purchase catastrophe reinsurance coverage for our catastrophe-exposed policies, and we seek to manage our exposures under this coverage so that no exposure to any one reinsurer is material to our ongoing business. Net retention of gross premium volume was 89% in 2010 and 90% in 2009. We do not purchase or sell finite reinsurance products or use other structures that would have the effect of discounting loss reserves.

The ceding of insurance does not legally discharge us from our primary liability for the full amount of the policies, and we will be required to pay the loss and bear collection risk if the reinsurer fails to meet its obligations under the reinsurance agreement. We attempt to minimize credit exposure to reinsurers through adherence to internal reinsurance guidelines. To become our reinsurance partner, prospective companies generally must: (i) maintain an A.M. Best Company (Best) or

24  |

Standard & Poor’s (S&P) rating of “A” (excellent) or better; (ii) maintain minimum capital and surplus of $500 million and (iii) provide collateral for recoverables in excess of an individually established amount. In addition, certain foreign reinsurers for our United States insurance operations must provide collateral equal to 100% of recoverables, with the exception of reinsurers who have been granted authorized status by an insurance company’s state of domicile. Lloyd’s syndicates generally must have a minimum of a “B” rating from Moody’s Investors Service (Moody’s) to be our reinsurers.

When appropriate, we pursue reinsurance commutations that involve the termination of ceded reinsurance contracts. Our commutation strategy related to ceded reinsurance contracts is to reduce credit exposure and eliminate administrative expenses associated with the run-off of reinsurance placed with certain reinsurers.

The following table displays balances recoverable from our ten largest reinsurers by group at December 31, 2010. The contractual obligations under reinsurance agreements are typically with individual subsidiaries of the group or syndicates at Lloyd’s and are not typically guaranteed by other group members or syndicates at Lloyd’s. These ten reinsurance groups represent approximately 68% of our $1.0 billion reinsurance recoverable balance before considering allowances for bad debts.

Reinsurers	A.M. Best Rating	Reinsurance Recoverable
		(dollars in thousands)
Munich Re Group	A+	$	167,148
Lloyd’s of London	A		131,960
Fairfax Financial Group	A		89,166

White Mountains Insurance Group	A-		31,607
Reinsurance recoverable on paid and unpaid losses for ten largest reinsurers			692,503
Total reinsurance recoverable on paid and unpaid losses		$	1,023,848

Reinsurance recoverable balances in the table above are shown before consideration of balances owed to reinsurers and any potential rights of offset, any collateral held by us and allowances for bad debts.

Reinsurance treaties are generally purchased on an annual basis and are subject to yearly renegotiations. In most circumstances, the reinsurer remains responsible for all business produced before termination. Treaties typically contain provisions concerning ceding commissions, required reports to reinsurers, responsibility for taxes, arbitration in the event of a dispute and provisions that allow us to demand that a reinsurer post letters of credit or assets as security if a reinsurer becomes an unauthorized reinsurer under applicable regulations or if its rating falls below an acceptable level.

See note 13 of the notes to consolidated financial statements and Management’s Discussion & Analysis of Financial Condition and Results of Operations for additional information about our reinsurance programs and exposures.

Investments

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

Total investment return includes items that impact net income, such as net investment income and net realized investment gains or losses, as well as changes in net unrealized gains on investments, which do not impact net income. In 2010, net investment income was $272.5 million and net realized investment gains were $36.4 million. During the year ended December 31, 2010, net unrealized gains on investments increased by $243.7 million. We do not lower the quality of our investment portfolio in order to enhance or maintain yields. We focus on long-term total investment return, understanding that the level of realized and unrealized investment gains or losses may vary from one period to the next.

We believe our investment performance is best analyzed from the review of total investment return over several years. The following table presents taxable equivalent total investment return before and after the effects of foreign currency movements.

ANNUAL TAXABLE EQUIVALENT TOTAL INVESTMENT RETURNS

	Years Ended December 31,															Weighted Average Five-Year Annual Return			Weighted Average Ten-Year Annual Return

⁽¹⁾ Includes short-term investments and cash and cash equivalents.

Taxable equivalent total investment return provides a measure of investment performance that considers the yield of both taxable and tax-exempt investments on an equivalent basis.

We monitor our portfolio to ensure that credit risk does not exceed prudent levels. S&P and Moody’s provide corporate and municipal debt ratings based on their assessments of the credit quality of an obligor with respect to a specific obligation. S&P’s ratings range from “AAA” (capacity to pay interest and repay principal is extremely strong) to “D” (debt is in payment default). Securities with ratings of “BBB” or higher are referred to as investment grade securities. Debt rated “BB” and below

26  |

is regarded by S&P as having predominantly speculative characteristics with respect to capacity to pay interest and repay principal. Moody’s ratings range from “Aaa” to “C” with ratings of “Baa” or higher considered investment grade.

Our fixed maturity portfolio has an average rating of “AA,” with approximately 93% 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 December 31, 2010, approximately 2% 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.

The following chart presents our fixed maturity portfolio, at estimated fair value, by rating category at December 31, 2010.

2010 CREDIT QUALITY OF FIXED MATURITY PORTFOLIO ($5.4 BILLION)

See “Market Risk Disclosures” in Management’s Discussion & Analysis of Financial Condition and Results of Operations for additional information about investments.

Non-Insurance Operations (Markel Ventures)

Through our wholly-owned subsidiary Markel Ventures, Inc., we own interests in various businesses that operate outside of the specialty insurance marketplace. These businesses are viewed by management as separate and distinct from our insurance operations. Local management teams oversee the day-to-day operations of these companies, while strategic decisions are made in conjunction with members of our executive management team, principally our President and Chief Investment Officer. The financial results of those companies in which we own controlling interests have been consolidated in our financial statements. The financial results of those companies in which we hold a noncontrolling interest are accounted for under the equity method of accounting.

Our strategy in making these private equity 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.

Markel Corporation & Subsidiaries

BUSINESS OVERVIEW (continued)

Our non-insurance operations, which are referred to collectively as Markel Ventures, are comprised of a diverse portfolio of companies from various industries, including manufacturers of dredging equipment, high-speed bakery equipment, laminated furniture products and food processing equipment, an owner and operator of manufactured housing communities, a real estate investment fund manager, a retail intelligence services company and a manager of behavioral health programs. Our non-insurance operations reported revenues of $166.5 million and net income to shareholders of $4.2 million in 2010.

In December 2010, we acquired controlling interests in RD Holdings, LLC (RetailData), a company that provides retail intelligence services, and Diamond Healthcare Corporation, a company that manages behavioral health programs throughout the United States. Both of these companies are headquartered in Richmond, Virginia. Since we consolidate our non-insurance operations on a one-month lag, the results for these two acquisitions will be included in our consolidated results beginning in the first quarter of 2011.

Shareholder Value

Our financial goals are to earn consistent underwriting and operating profits and superior investment returns to build shareholder value. More specifically, 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. For the year ended December 31, 2010, book value per share increased 16% primarily due to net income to shareholders of $266.8 million and a $163.5 million increase in net unrealized gains on investments, net of taxes. For the year ended December 31, 2009, book value per share increased 27% primarily due to a $374.4 million increase in net unrealized gains on investments, net of taxes, and net income to shareholders of $201.6 million. Over the past five years, we have grown book value per share at a compound annual rate of 13% to $326.36 per share.

The following graph presents book value per share for the past five years.

28  |

Regulatory Environment

Our insurance subsidiaries are subject to regulation and supervision by the insurance regulatory authorities of the various jurisdictions in which they conduct business. This regulation is intended for the benefit of policyholders rather than shareholders or holders of debt securities.

United States Insurance Regulation. In the United States, state regulatory authorities have broad regulatory, supervisory and administrative powers relating to solvency standards, the licensing of insurers and their agents, the approval of forms and policies used, the nature of, and limitations on, insurers’ investments, the form and content of annual statements and other reports on the financial condition of such insurers and the establishment of loss reserves. Additionally, the business written in the Specialty Admitted segment typically is subject to regulatory rate and form review.

As an insurance holding company, we are also subject to certain state laws. Under these laws, insurance departments may, at any time, examine us, require disclosure of material transactions, require approval of certain extraordinary transactions, such as extraordinary dividends from our insurance subsidiaries to us, or require approval of changes in control of an insurer or an insurance holding company. Generally, control for these purposes is defined as ownership or voting power of 10% or more of a company’s shares.

The laws of the domicile states of our insurance subsidiaries govern the amount of dividends that may be paid to our holding company, Markel Corporation. Generally, statutes in the domicile states of our insurance subsidiaries require prior approval for payment of extraordinary as opposed to ordinary dividends. At December 31, 2010, our United States insurance subsidiaries could pay up to $197.0 million during the following 12 months under the ordinary dividend regulations.

United Kingdom Insurance Regulation. With the enactment of the Financial Services and Markets Act, the United Kingdom government authorized the Financial Services Authority (FSA) to supervise all securities, banking and insurance businesses, including Lloyd’s. The FSA oversees compliance with established periodic auditing and reporting requirements, risk assessment reviews, minimum solvency margins and individual capital assessment requirements, dividend restrictions, restrictions governing the appointment of key officers, restrictions governing controlling ownership interests and various other requirements. Both MIICL and Markel Syndicate Management Limited are authorized and regulated by the FSA. We are required to provide 14 days advance notice to the FSA for any dividends from MIICL. In addition, our United Kingdom insurance subsidiaries must comply with the United Kingdom Companies Act of 2006, which provides that dividends may only be paid out of profits available for that purpose.

Ratings

Financial stability and strength are important purchase considerations of policyholders and insurance agents and brokers. Because an insurance premium paid today purchases coverage for losses that might not be paid for many years, the financial viability of the insurer is of critical concern. Various independent rating agencies provide information and assign ratings to assist buyers in their search for financially sound insurers. Rating agencies periodically re-evaluate assigned ratings based upon changes in the insurer’s operating results, financial condition or other significant factors influencing the insurer’s business. Changes in assigned ratings could have an adverse impact on an insurer’s ability to write new business.

Best assigns financial strength ratings (FSRs) to P&C insurance companies based on quantitative criteria such as profitability, leverage and liquidity, as well as qualitative assessments such as the spread of risk, the adequacy and soundness of reinsurance, the quality and estimated market value of assets, the adequacy of loss reserves and surplus and the competence, experience and integrity of management. Best’s FSRs range from “A++” (superior) to “F” (in liquidation).

Six of our insurance subsidiaries rated by Best have been assigned an FSR of “A” (excellent), one is rated “A-” (excellent) and one is rated “B++” (good). Markel Syndicate 3000 has been assigned an FSR of “A” (excellent) by Best.

In addition to Best, seven of our insurance subsidiaries are rated by Fitch Ratings (Fitch), an independent rating agency. All seven of our insurance subsidiaries rated by Fitch have been assigned an FSR of “A” (strong).

The various rating agencies typically charge companies fees for the rating and other services they provide. During 2010, we paid rating agencies, including Best and Fitch, $0.4 million for their services.

Risk Factors

A wide range of factors could materially affect our future prospects and performance. The matters addressed under “Safe Harbor and Cautionary Statements,” “Critical Accounting Estimates” and “Market Risk Disclosures” in Management’s Discussion and Analysis of Financial Condition and Results of Operations and other information included or incorporated in this report describe most of the significant risks that could affect our operations and financial results. We are also subject to the following risks.

We may experience losses from catastrophes. As a property and casualty insurance company, we may experience losses from man-made or natural catastrophes. Catastrophes may have a material adverse effect on operations. Catastrophes include, but are not limited to, windstorms, hurricanes, earthquakes, tornadoes, hail, severe winter weather and fires and may include terrorist events. We cannot predict how severe a particular catastrophe will be before it occurs. The extent of losses from catastrophes is a function of the total amount of losses incurred, the number of insureds affected, the frequency and severity of the events, the effectiveness of our catastrophe risk management program and the adequacy of our reinsurance coverage. Most catastrophes occur over a small geographic area; however, some catastrophes may produce significant damage in large, heavily populated areas. If, as many forecast, climate change results in an increase in the frequency and severity of weather-related catastrophes, we may experience additional catastrophe-related losses.

30  |

Our results may be affected because actual insured losses differ from our loss reserves. Significant periods of time often elapse between the occurrence of an insured loss, the reporting of the loss to us and our payment of that loss. To recognize liabilities for unpaid losses, we establish reserves as balance sheet liabilities representing estimates of amounts needed to pay reported and unreported losses and the related loss adjustment expenses. The process of estimating loss reserves is a difficult and complex exercise involving many variables and subjective judgments. This process may become more difficult if we experience a period of rising inflation. As part of the reserving process, we review historical data and consider the impact of such factors as:

• trends in claim frequency and severity,

• changes in operations,

• emerging economic and social trends,

• uncertainties relating to asbestos and environmental exposures,

• inflation or deflation, and

• changes in the regulatory and litigation environments.

This process assumes that past experience, adjusted for the effects of current developments and anticipated trends, is an appropriate basis for predicting future events. There is no precise method, however, for evaluating the impact of any specific factor on the adequacy of reserves, and actual results will differ from original estimates. As part of the reserving process, we regularly review our loss reserves and make adjustments as necessary. Future increases in loss reserves will result in additional charges to earnings.

We are subject to regulation by insurance regulatory authorities that may affect our ability to implement our business objectives. Our insurance subsidiaries are subject to supervision and regulation by the insurance regulatory authorities in the various jurisdictions in which they conduct business. This regulation is intended for the benefit of policyholders rather than shareholders or holders of debt securities. Insurance regulatory authorities have broad regulatory, supervisory and administrative powers relating to solvency standards, licensing, coverage requirements, policy rates and forms and the form and content of financial reports. In light of recent economic conditions, regulatory and legislative authorities are implementing enhanced or new regulatory requirements intended to prevent future crises or otherwise assure the stability of financial institutions. Regulatory authorities also may seek to exercise their supervisory or enforcement authority in new or more aggressive ways, such as imposing increased capital requirements. Any such actions, if they occurred, could affect the competitive market and the way we conduct our business and manage our capital. As a result, such actions could materially affect our results of operations, financial condition and liquidity.

Our ability to make payments on debt or other obligations depends on the receipt of funds from our subsidiaries. We are a holding company, and substantially all of our operations are conducted through our regulated subsidiaries. As a result, our cash flow and our ability to service our debt are dependent upon the earnings of our subsidiaries and on the distribution of earnings, loans or other payments by our subsidiaries to us. In addition, payment of dividends by our insurance subsidiaries may require prior regulatory notice or approval.

BUSINESS OVERVIEW (continued)

Our investment results may be impacted by changes in interest rates, U.S. and international monetary and fiscal policies as well as broader economic conditions. We receive premiums from customers for insuring their risks. We invest these funds until they are needed to pay policyholder claims or until they are recognized as profits. Fluctuations in the value of our investment portfolio can occur as a result of changes in interest rates, U.S. and international monetary and fiscal policies as well as broader economic conditions (including, for example, equity market conditions and significant inflation or deflation). Our investment results may be impacted by one or more of these factors.

Competition in the property and casualty insurance industry could adversely affect our ability to grow or maintain premium volume. Among our competitive strengths have been our specialty product focus and our niche market strategy. These strengths also make us vulnerable in periods of intense competition to actions by other insurance companies who seek to write additional premiums without appropriate regard for ultimate profitability. During soft markets, it is very difficult for us to grow or maintain premium volume levels without sacrificing underwriting profits. If we are not successful in maintaining rates or achieving rate increases, it may be difficult for us to improve underwriting margins and grow or maintain premium volume levels.

We invest a significant portion of our invested assets in equity securities, which may result in significant variability in our investment results and may adversely impact shareholders’ equity. Additionally, our equity investment portfolio is concentrated and declines in the value of these significant investments could adversely affect our financial results. Equity securities were 54% and 49% of our shareholders’ equity at December 31, 2010 and 2009, respectively. Equity securities have historically produced higher returns than fixed maturities; however, investing in equity securities may result in significant variability in investment returns from one period to the next. If recent levels of market volatility persist, we could experience significant declines in the fair value of our equity investment portfolio, which would result in a material decrease in shareholders’ equity. Our equity portfolio is concentrated in particular issuers and industries and, as a result, a decline in the fair value of these significant investments also could result in a material decrease in shareholders’ equity. A material decrease in shareholders’ equity may adversely impact our ability to carry out our business plans.

Deterioration in financial markets could lead to investment losses and adverse effects on our business. The severe downturn in the public debt and equity markets beginning in 2008, reflecting uncertainties associated with the mortgage and credit crises, worsening economic conditions, widening of credit spreads, bankruptcies and government intervention in large financial institutions, resulted in significant realized and unrealized losses in our investment portfolio. In the event of another major financial crisis (for example, a significant and widespread increase in municipal bond defaults), we could incur substantial realized and unrealized investment losses in future periods, which would have an adverse impact on our results of operations, financial condition, debt and financial strength ratings, insurance subsidiaries’ capital and ability to access capital markets.

We rely on reinsurance and bear collection risk if the reinsurer fails to meet its obligations under the reinsurance agreement. We purchase reinsurance in order to reduce our retention on individual risks and to have the ability to underwrite policies with sufficient limits to meet policyholder needs. The ceding of insurance does not legally discharge us from our primary liability for the full amount of the policies. Such reliance on reinsurance may create credit risk as a result of the reinsurer’s inability or unwillingness to pay reinsurance claims when due. Deterioration in the credit quality of existing reinsurers or disputes over the terms of reinsurance could result in additional charges to earnings, which may adversely impact our results of operations and financial condition.

32  |

Our information technology systems may fail or suffer a security breach, which could adversely affect our business or reputation. Our business is dependent upon the successful functioning and security of our computer systems. Among other things, we rely on these systems to interact with producers and insureds, to perform actuarial and other modeling functions, to underwrite business, to prepare policies and process premiums, to process claims and make claims payments, and to prepare internal and external financial statements and information. A significant failure of these systems, whether because of a breakdown, natural disaster or an attack on our systems, could have a material adverse affect on our business. In addition, a security breach of our computer systems could damage our reputation or result in material liabilities.

The integration of acquired companies may not be as successful as we anticipate. We have recently engaged in a number of acquisitions in an effort to achieve profitable growth in our insurance operations and to create additional value on a diversified basis in our non-insurance operations. Acquisitions present operational, strategic and financial risks, as well as risks associated with liabilities arising from the previous operations of the acquired companies. Assimilation of the operations and personnel of acquired companies (especially those that are outside of our core insurance operations) may prove more difficult than anticipated, which may result in failure to achieve financial objectives associated with the acquisition or diversion of management attention. In addition, integration of formerly privately-held companies into the management and internal control and financial reporting systems of a publicly-held company presents additional risks.

Associates

At December 31, 2010, we had approximately 4,800 employees, of which approximately 2,600 were employed within our insurance operations and approximately 2,200 were employed within our non-insurance operations.

Markel Corporation & Subsidiaries

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Summary of Significant Accounting Policies

Markel Corporation is a diverse financial holding company serving a variety of niche markets. Markel Corporation’s principal business markets and underwrites specialty insurance products and programs and operates in three segments of the specialty insurance marketplace: the Excess and Surplus Lines, the Specialty Admitted and the London markets. Markel Corporation also owns interests in various businesses that operate outside of the specialty insurance marketplace.

a) Basis of Presentation. 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 all subsidiaries (the Company). All significant intercompany balances and transactions have been eliminated in consolidation. The Company consolidates the results of its non-insurance subsidiaries on a one-month lag. Certain prior year amounts have been reclassified to conform to the current presentation.

b) Use of Estimates. 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. Management periodically reviews its estimates and assumptions. These reviews include evaluating the adequacy of reserves for unpaid losses and loss adjustment expenses, litigation contingencies, the reinsurance allowance for doubtful accounts and income tax liabilities, as well as analyzing the recoverability of deferred tax assets, assessing goodwill for impairment and evaluating the investment portfolio for other-than-temporary declines in estimated fair value. Actual results may differ from the estimates and assumptions used in preparing the consolidated financial statements.

c) Investments. Available-for-sale investments are recorded at estimated fair value. Unrealized gains and losses on investments, net of deferred income taxes, are included in accumulated other comprehensive income in shareholders’ equity. 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.

Premiums and discounts are amortized or accreted over the lives of the related fixed maturities as an adjustment to the yield using the effective interest method. Dividend and interest income are recognized when earned. Realized investment gains or losses are included in earnings. Realized gains or losses from sales of investments are derived using the first-in, first-out method.

d) Cash and Cash Equivalents. The Company considers all investments with original maturities of 90 days or less to be cash equivalents. The carrying value of the Company’s cash and cash equivalents approximates fair value.

e) Reinsurance Recoverables. Amounts recoverable from reinsurers are estimated in a manner consistent with the claim liability associated with the reinsured business. Allowances are established for amounts deemed uncollectible and reinsurance recoverables are recorded net of these allowances. The Company evaluates the financial condition of its reinsurers and monitors concentration risk to minimize its exposure to significant losses from individual reinsurers.

f) Deferred Policy Acquisition Costs. Costs directly related to the acquisition of insurance premiums, such as commissions to agents and brokers, are deferred and amortized over the related policy period, generally one year. Commissions received related to reinsurance premiums ceded are netted against broker commissions and other acquisition costs in determining acquisition costs eligible for deferral. To the extent that future policy revenues on existing policies are not adequate to cover related costs and expenses, deferred policy acquisition costs are charged to earnings. The Company does not consider anticipated investment income in determining whether a premium deficiency exists.

1. Summary of Significant Accounting Policies (continued)

g) Goodwill and Intangible Assets. Goodwill and indefinite-lived intangible assets are tested for impairment at least annually. The Company completes its annual test during the fourth quarter of each year based upon the results of operations through September 30. Intangible assets with finite lives are amortized using the straight-line method over their estimated useful lives, generally three to 25 years, and are reviewed for impairment when events or circumstances indicate that their carrying value may not be recoverable.

h) Property and Equipment. Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization of property and equipment are calculated using the straight-line method over the estimated useful lives (generally, the life of the lease for leasehold improvements, 20 to 40 years for buildings, three to 15 years for furniture and equipment and three to 25 years for other property and equipment).

i) Income Taxes. The Company records deferred income taxes to reflect the net tax effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and their tax bases. Deferred tax assets are reduced by a valuation allowance when management believes it is more likely than not that some, or all, of the deferred tax assets will not be realized. The Company recognizes the tax benefit from an uncertain tax position taken or expected to be taken in income tax returns only if it is more likely than not that the tax position will be sustained upon examination by tax authorities, based on the technical merits of the position. Tax positions that meet the more likely than not threshold are then measured using a probability weighted approach, whereby the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement is recognized. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense (benefit).

j) Unpaid Losses and Loss Adjustment Expenses. Unpaid losses and loss adjustment expenses are based on evaluations of reported claims and estimates for losses and loss adjustment expenses incurred but not reported. Estimates for losses and loss adjustment expenses incurred but not reported are based on reserve development studies, among other things. The Company does not discount reserves for losses and loss adjustment expenses to reflect estimated present value. The reserves recorded are estimates, and the ultimate liability may be greater than or less than the estimates.

k) Revenue Recognition. Insurance premiums are earned on a pro rata basis over the policy period, generally one year. The cost of reinsurance is initially recorded as prepaid reinsurance premiums and is amortized over the reinsurance contract period in proportion to the amount of insurance protection provided. Premiums ceded are netted against premiums written. The Company uses the periodic method to account for assumed reinsurance from foreign reinsurers. The Company’s foreign reinsurers provide sufficient information to record foreign assumed business in the same manner as the Company records assumed business from United States reinsurers. Other revenues primarily consist of sales of products manufactured by the Company’s non-insurance operations. Revenue from manufactured products is generally recognized at the time title transfers to the customer, which occurs at the point of shipment or delivery to the customer, depending on the terms of the sales arrangement.

l) Stock-based Compensation. Stock-based compensation expense is recognized as part of underwriting, acquisition and insurance expenses over the requisite service period. Stock-based compensation expense, net of taxes, was $2.1 million in 2010, $1.8 million in 2009 and $1.3 million in 2008.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

1. Summary of Significant Accounting Policies (continued)

m) Foreign Currency Translation. The functional currencies of the Company’s foreign operations are the currencies in which the majority of their business is transacted. Assets and liabilities of foreign operations are translated into the United States Dollar using the exchange rates in effect at the balance sheet date. Revenues and expenses of foreign operations are translated using the average exchange rate for the period. Gains or losses from translating the financial statements of foreign operations are included, net of taxes, in shareholders’ equity as a component of accumulated other comprehensive income. Gains and losses arising from transactions denominated in a foreign currency, other than a functional currency, are included in net income (loss).

The Company manages its exposure to foreign currency risk primarily by matching assets and liabilities denominated in the same currency. To the extent that assets and liabilities in foreign currencies are not matched, the Company is exposed to foreign currency risk. For functional currencies, the related exchange rate fluctuations are reflected in other comprehensive income (loss).

n) Derivative Financial Instruments. Derivative instruments, including derivative instruments resulting from hedging activities, are measured at fair value and recognized as either assets or liabilities on the consolidated balance sheets. The changes in fair value of derivatives are recognized in earnings unless the derivative is designated as a hedge and qualifies for hedge accounting.

The Company’s foreign currency forward contracts are generally designated and qualified as hedges of a net investment in a foreign operation. The effective portion of the change in fair value resulting from these hedges is reported in currency translation adjustments as part of other comprehensive income (loss). The ineffective portion of the change in fair value is recognized in earnings.

o) Comprehensive Income (Loss). Comprehensive income (loss) represents all changes in equity that result from recognized transactions and other economic events during the period. Other comprehensive income (loss) refers to revenues, expenses, gains and losses that under U.S. GAAP are included in comprehensive income (loss) but excluded from net income (loss), such as unrealized gains or losses on investments, foreign currency translation adjustments and changes in net actuarial pension loss.

p) Net Income (Loss) Per Share. Basic net income (loss) per share is computed by dividing net income (loss) to shareholders by the weighted average number of common shares outstanding during the year. Diluted net income (loss) per share is computed by dividing net income (loss) to shareholders by the weighted average number of common shares and dilutive potential common shares outstanding during the year.

q) Recent Accounting Pronouncements. Effective in the first quarter of 2010, the Company adopted Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) No. 2010-06, Improving Disclosures about Fair Value Measurements, which expands disclosure requirements related to fair value measurements. ASU No. 2010-06 requires disclosure of the amounts of and reasons for significant transfers into and out of Level 1 and Level 2 fair value measurements. This guidance also requires gross rather than net disclosures about purchases, sales, issuances and settlements relating to Level 3 fair value measurements. Disclosures about the valuation techniques and inputs used to measure fair value for Level 2 and Level 3 fair value measurements are required as well. Since ASU No. 2010-06 addresses financial statement disclosures only, the adoption of this guidance did not have an impact on the Company’s financial position, results of operations or cash flows. The Company has included the disclosures required by ASU No. 2010-06 in note 12.

1. Summary of Significant Accounting Policies (continued)

In June 2009, the FASB issued Statement of Financial Accounting Standards (Statement) No. 167, Amendments to FASB Interpretation No. 46(R). In December 2009, the FASB issued ASU No. 2009-17, Improvements to Financial Reporting by Enterprises Involved with Variable Interest Entities, to amend their codification for Statement No. 167. This guidance removes the scope exception for qualifying special-purpose entities, includes new criteria for determining the primary beneficiary of a variable interest entity and increases the frequency of required assessments to determine whether an entity is the primary beneficiary of a variable interest entity. In January 2010, the FASB decided to indefinitely defer the consolidation requirements of ASU No. 2009-17 for interests in certain investment entities. The FASB also decided to revise the provisions of ASU No. 2009-17 for determining whether service-provider or decision-maker fee arrangements represent a variable interest. Both the provisions of ASU No. 2009-17 as issued and the subsequent revisions to this guidance became effective for the Company on January 1, 2010. The adoption of this guidance did not have an impact on the Company’s financial position, results of operations or cash flows.

Effective July 1, 2010, the Company adopted ASU No. 2010-11, Scope Exception Related to Embedded Credit Derivatives, which clarifies that the only type of embedded credit derivatives that are exempt from bifurcation requirements are those that relate to the subordination of one financial instrument to another. This guidance requires analysis of embedded credit derivative features other than subordination to determine if they require bifurcation and separate accounting treatment. The adoption of ASU No. 2010-11 did not have an impact on the Company’s financial position, results of operations or cash flows.

In October 2010, the FASB issued ASU No. 2010-26, Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts, to address diversity in practice within the insurance industry regarding the interpretation of which costs relating to the acquisition of new or renewal insurance contracts qualify for deferral. This guidance modifies the definition of the types of costs incurred by insurance companies that can be capitalized in the acquisition of new and renewal contracts. This guidance specifies that a cost must be directly related to the successful acquisition of a new or renewal insurance contract in order to be capitalized. ASU No. 2010-26 becomes effective for the Company beginning January 1, 2012, and would allow, but not require, retrospective application. The Company is currently evaluating ASU No. 2010-26 to determine the potential impact that adopting this standard will have on its consolidated financial statements.

At December 31, 2009, the Company held 190 securities with a total estimated fair value of $955.6 million and gross unrealized losses of $54.3 million. Of these 190 securities, 78 securities had been in a continuous unrealized loss position for greater than one year and had a total estimated fair value of $313.4 million and gross unrealized losses of $14.0 million. All 78 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.

46  |

2. Investments (continued)

For equity securities, a decline in fair value that is considered to be other-than-temporary is recognized in net income (loss) 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 (loss) 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 (loss), 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.

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, but not limited to, decisions to reposition the investment portfolio, potential sales of investments to meet cash flow needs and potential sales of investments to capitalize on favorable pricing. Additional information on the methodology and significant inputs, by security type, that the Company used to determine the amount of credit loss recognized on fixed maturities with declines in fair value below amortized cost that were considered to be other-than-temporary is provided below.

Residential mortgage-backed securities. For mortgage-backed securities, credit impairment is assessed by estimating future cash flows from the underlying mortgage loans and interest payments. The cash flow estimate incorporates actual cash flows from the mortgage-backed securities through the current period and then projects the remaining cash flows using a number of assumptions, including prepayment rates, default rates, recovery rates on foreclosed properties and loss severity assumptions. Management develops specific assumptions using market data and internal estimates, as well as estimates from rating agencies and other third party sources. Default rates are estimated by considering current underlying mortgage loan performance and expectations of future performance. Estimates of future cash flows are discounted to present value. If the present value of expected cash flows is less than the amortized cost, the Company recognizes the estimated credit loss in net income (loss).

Corporate bonds. For corporate bonds, credit impairment is assessed by evaluating the underlying issuer. As part of this assessment, the Company analyzes various factors, including the following:

• fundamentals of the issuer, including current and projected earnings, current liquidity position and ability to raise capital;

• fundamentals of the industry in which the issuer operates;

• expectations of defaults and recovery rates;

• changes in ratings by rating agencies;

• other relevant market considerations; and

• receipt of interest payments

Default probabilities and recovery rates from rating agencies are key factors used in calculating the credit loss. Additional research of the industry and issuer is completed to determine if there is any current information that may affect the fixed maturity or its issuer in a negative manner and require an adjustment to the cash flow assumptions.

Foreign income tax expense (benefit) includes United States tax expense (benefit) on foreign operations.

In 2010, income tax expense included a benefit from a reduction in the provision for interest and penalties of $3.9 million. In 2009, income tax benefit included an increase in the provision for interest and penalties of $2.7 million. In 2008, income tax benefit included a benefit from a reduction in the provision for interest and penalties of $3.5 million. At December 31, 2010 and 2009, other liabilities on the consolidated balance sheets included $2.4 million and $6.3 million, respectively, for potential payment of interest and penalties.

State income tax expense is not material to the consolidated financial statements.

The Company made income tax payments of $24.0 million, $21.2 million and $29.0 million in 2010, 2009 and 2008, respectively. Income taxes receivable were $15.9 million and $13.2 million at December 31, 2010 and 2009, respectively, and were included in other assets on the consolidated balance sheets. The income tax receivables at December 31, 2010 and 2009 were due in part to the carryback of $27.5 million and $38.7 million, respectively, of capital losses generated as a result of sales of equity securities and fixed maturities that had tax bases in excess of fair value on the dates of sale.

Reconciliations of the United States corporate income tax rate to the effective tax rate on income (loss) before income taxes are presented in the following table.

The 2010 effective tax rate included a 13% income tax benefit related to foreign operations, of which 11% is a result of a change in the Company’s plans regarding the amount of earnings considered permanently reinvested in foreign subsidiaries. The 2009 effective tax rate included a 21% income tax benefit related to foreign operations, of which 17% is the result of a one-time tax benefit related to a change in the United Kingdom tax law that became effective in the third quarter of 2009.

Total gross deferred tax liabilities		341,578		281,218
NET DEFERRED TAX ASSET	$	63,263	$	161,156

The decrease in the net deferred tax asset in 2010 was primarily due to an increase in net unrealized gains on investments and a decrease in net operating loss carryforwards during 2010. The net deferred tax assets at December 31, 2010 and 2009 were included in other assets on the consolidated balance sheets.

In December 2008, Markel Corporation received $110.0 million in distributions made by Markel International. In January 2009, Markel Corporation received an additional $101.7 million in distributions made by Markel International. Pursuant to guidance included in FASB ASC 740, Income Taxes, approximately $46 million in foreign paid taxes became available for use by the Company as foreign tax credits as a result of these distributions. At December 31, 2010, the Company had tax credit carryforwards of $25.6 million. The earliest any of these credits will expire is 2019.

At December 31, 2010, the Company had net operating losses of $317.6 million. These losses can be carried forward indefinitely to offset future taxable income in the United Kingdom. Of the $317.6 million of net operating losses, $98.9 million also can be utilized to offset future Markel Capital Limited, a wholly-owned subsidiary, income that is taxable in the United States. The Company’s ability to utilize these losses in the United States expires between the years 2019 and 2026.

At December 31, 2010, the Company had unused capital losses of $7.8 million. The Company’s ability to utilize these losses expires in 2015.

The Company estimates that it will realize $341.6 million of the gross deferred tax assets, including net operating losses, recorded at December 31, 2010 through the reversal of existing temporary differences attributable to the gross deferred tax liabilities. The Company believes that it is more likely than not that it will realize $63.3 million of gross deferred tax assets by generating future taxable income and by using

prudent and feasible tax planning strategies if future taxable income is not sufficient. While management believes that a valuation allowance at December 31, 2010 and 2009 was not necessary, changes in management’s estimate of future taxable income to be generated by its foreign subsidiaries, changes in the Company’s ability to use tax planning strategies or significant declines in the estimated fair value of investments could result in a need to record a valuation allowance through a charge to earnings.

At December 31, 2010, the Company had unrecognized tax benefits of $24.6 million. If recognized, $19.3 million of these tax benefits would decrease the annual effective tax rate. The Company does not currently anticipate any significant changes in unrecognized tax benefits during 2011.

The following table presents a reconciliation of beginning and ending unrecognized tax benefits.

	Years Ended December 31,

Settlement with taxing authorities		—			(1,858	)
Lapse of statute of limitations		(816	)		—
UNRECOGNIZED TAX BENEFITS, END OF YEAR	$	24,585		$	24,940

The $42.6 million decrease in 2009 for tax positions taken in prior years represented future tax return benefits that the Company no longer anticipated recognizing in its consolidated financial statements.

Provisions for United States income taxes on undistributed earnings of foreign subsidiaries are made only on those amounts in excess of the amounts that are considered to be permanently reinvested. As of December 31, 2010, earnings of the Company’s foreign subsidiaries through 2010 are considered permanently reinvested and no provision for United States income taxes has been recorded. It is not practicable to determine the amount of unrecognized deferred tax liabilities associated with such earnings due to the complexity of this calculation.

The Company is subject to income tax in the United States and in foreign jurisdictions. With few exceptions, the Company is no longer subject to income tax examination by tax authorities for years ended before January 1, 2007.

GROSS RESERVES FOR LOSSES AND LOSS ADJUSTMENT EXPENSES, END OF YEAR	$	5,398,406		$	5,427,096		$	5,492,339

Beginning of year net reserves for losses and loss adjustment expenses are adjusted, when applicable, for the impact of changes in foreign currency rates, commutations and other items. In 2010, beginning of year net reserves for losses and loss adjustment expenses were decreased by a movement of $19.1 million in foreign currency rates of exchange, which was offset in part by increases for other items including commutations. In 2009, beginning of year net reserves for losses and loss adjustment expenses were increased by a movement of $74.8 million in foreign currency rates of exchange, most notably between the United States Dollar and the United Kingdom Sterling. In 2008, beginning of year net reserves for losses and loss adjustment expenses were decreased by a movement of $195.7 million in foreign currency rates of exchange, most notably between the United States Dollar and the United Kingdom Sterling.

As a result of its acquisition of Aspen Holdings, Inc. (Aspen) in 2010, the Company recorded net reserves for losses and loss adjustment expenses of $182.3 million. These reserves were recorded at fair value as part of the Company’s purchase accounting. See note 21 for a discussion of the Company’s acquisition of Aspen.

In 2010, incurred losses and loss adjustment expenses included $278.0 million of favorable development on prior years’ loss reserves, which was primarily due to $214.4 million of loss reserve redundancies experienced at Markel International and on the professional and products liability programs within the

8. Unpaid Losses and Loss Adjustment Expenses (continued)

Excess and Surplus Lines segment as actual claims reporting patterns on prior accident years have been more favorable than initially anticipated within the Company’s actuarial analyses.

In 2009, incurred losses and loss adjustment expenses included $235.3 million of favorable development on prior years’ loss reserves, which was primarily due to $205.6 million of loss reserve redundancies experienced at Markel International and on the professional and products liability programs within the Excess and Surplus Lines segment as actual claims reporting patterns on prior accident years were more favorable than initially anticipated within the Company’s actuarial analyses. The favorable development on prior years’ loss reserves in 2009 was partially offset by $10.0 million of adverse development on asbestos and environmental loss reserves following the Company’s annual review of these exposures.

Current year incurred losses and loss adjustment expenses for 2008 included $91.1 million of estimated net losses on Hurricanes Gustav and Ike (2008 Hurricanes). The estimated net losses on the 2008 Hurricanes were net of estimated reinsurance recoverables of $58.6 million.

In 2008, incurred losses and loss adjustment expenses included $163.8 million of favorable development on prior years’ loss reserves, which was primarily due to $149.6 million of loss reserve redundancies experienced at Markel International and on the professional and products liability programs within the Excess and Surplus Lines segment as actual claims reporting patterns on prior accident years were more favorable than initially anticipated within the Company’s actuarial analyses. The favorable development on prior years’ loss reserves in 2008 was partially offset by $24.9 million of adverse development on prior years’ loss reserves on asbestos and environmental exposures and related reinsurance bad debt.

During the third quarter of each of the past three years, the Company completed an in-depth, actuarial review of its asbestos and environmental exposures. During the 2010 review, the Company determined that no adjustment to loss reserves was necessary. During the 2009 review, the Company increased its estimate of the number of claims that will ultimately be closed with an indemnity payment. During the 2008 review, the Company noted that claims had been closed with total indemnity payments that were higher than had been anticipated, and as a result of this higher than expected average severity on closed claims, the Company’s actuaries updated their average severity assumptions for both open claims and claims incurred but not yet reported. In 2009 and 2008, the Company’s actuarial estimates of the ultimate liability for asbestos and environmental loss reserves were increased, and management increased prior years’ loss reserves for asbestos and environmental exposures accordingly.

Inherent in the Company’s reserving practices is the desire to establish loss reserves that are more likely redundant than deficient. As such, the Company seeks to establish loss reserves that will ultimately prove to be adequate. Furthermore, the Company’s philosophy is to price its insurance products to make an underwriting profit. Management continually attempts to improve its loss estimation process by refining its ability to analyze loss development patterns, claim payments and other information, but uncertainty remains regarding the potential for adverse development of estimated ultimate liabilities.

The Company uses a variety of techniques to establish the liabilities for unpaid losses and loss adjustment expenses, all of which involve significant judgments and assumptions. These techniques include detailed statistical analysis of past claim reporting, settlement activity, claim frequency and severity, policyholder loss experience, industry loss experience and changes in market conditions, policy forms and exposures. Greater judgment may be required when new product lines are introduced or when there have been changes in claims handling practices, as the statistical data available may be insufficient. The Company’s estimates reflect implicit and explicit assumptions regarding the potential effects of external factors, including economic and social inflation, judicial decisions, law changes, general economic conditions and recent trends in these factors. In some of the Company’s markets, and where the Company acts as a reinsurer, the timing and amount of information reported about underlying claims are in the control of third parties. This can also affect estimates and require re-estimation as new information becomes available.

The Company believes the process of evaluating past experience, adjusted for the effects of current developments and anticipated trends, is an appropriate basis for predicting future events. Management currently believes the Company’s gross and net reserves, including the reserves for environmental and asbestos exposures, are adequate. However, there is no precise method for evaluating the impact of any significant factor on the adequacy of reserves, and actual results will differ from original estimates.

b) The Company’s exposure to asbestos and environmental (A&E) claims results from policies written by acquired insurance operations before their acquisitions by the Company. The Company’s exposure to A&E claims originated from umbrella, excess and commercial general liability (CGL) insurance policies and assumed reinsurance contracts that were written on an occurrence basis from the 1970s to mid-1980s. Exposure also originated from claims-made policies that were designed to cover environmental risks provided that all other terms and conditions of the policy were met.

A&E claims include property damage and clean-up costs related to pollution, as well as personal injury allegedly arising from exposure to hazardous materials. After 1986, the Company began underwriting CGL coverage with pollution exclusions, and in some lines of business the Company began using a claims-made form. These changes significantly reduced the Company’s exposure to future A&E claims on post-1986 business.

The following table provides a reconciliation of beginning and ending A&E reserves for losses and loss adjustment expenses, which are a component of consolidated unpaid losses and loss adjustment expenses.

Incurred losses and loss adjustment expenses for 2009 and 2008 were primarily due to adverse development of asbestos-related reserves. At December 31, 2010, asbestos-related reserves were $270.3 million and $154.4 million on a gross and net basis, respectively.

Net reserves for reported claims and net incurred but not reported reserves for A&E exposures were $131.6 million and $84.4 million, respectively, at December 31, 2010. Inception-to-date net paid losses and loss adjustment expenses for A&E related exposures totaled $355.7 million at December 31, 2010, which includes $67.2 million of litigation-related expense.

8. Unpaid Losses and Loss Adjustment Expenses (continued)

The Company’s reserves for losses and loss adjustment expenses related to A&E exposures represent management’s best estimate of ultimate settlement values. A&E reserves are monitored by management, and the Company’s statistical analysis of these reserves is reviewed by the Company’s independent actuaries. A&E exposures are subject to significant uncertainty due to potential loss severity and frequency resulting from the uncertain and unfavorable legal climate. A&E reserves could be subject to increases in the future; however, management believes the Company’s gross and net A&E reserves at December 31, 2010 are adequate.

On June 9, 2010, the Company entered into a revolving credit facility, which provides $270 million of capacity for working capital and other general corporate purposes. The Company may increase the capacity of the revolving credit facility to $350 million subject to certain terms and conditions. The Company may select from two interest rate options for balances outstanding under the facility and pays a commitment fee (0.38% at December 31, 2010) on the unused portion of the facility based on the Company’s debt to equity leverage ratio as calculated under the agreement. At December 31, 2010, the Company had no borrowings outstanding related to the facility. This facility replaced the Company’s previous $375 million revolving credit facility and expires in June 2013.

At December 31, 2010, the Company was in compliance with all covenants contained in its revolving credit facility. To the extent that the Company is not in compliance with its covenants, the Company’s access to the credit facility could be restricted. While the Company believes this to be unlikely, the inability to access the credit facility could adversely affect the Company’s liquidity.

On September 22, 2009, the Company issued $350 million of 7.125% unsecured senior notes due September 30, 2019. Net proceeds to the Company were $347.2 million, which were used for general corporate purposes, including acquisitions.

9. Senior Long-Term Debt and Other Debt (continued)

The Company’s 7.125% unsecured senior notes are redeemable by the Company at any time. The Company’s 7.50% unsecured senior debentures are redeemable by the Company at any time after August 22, 2011. None of the Company’s other senior long-term debt is redeemable. None of the Company’s senior long-term debt is subject to any sinking fund requirements.

The Company’s subsidiary debt is primarily associated with its non-insurance operations and is non-recourse to the holding company. The debt of the Company’s non-insurance subsidiaries generally is secured by the assets of those subsidiaries.

The estimated fair value based on quoted market prices of the Company’s senior long-term debt and other debt was $1.1 billion and $1.0 billion at December 31, 2010 and 2009, respectively.

The following table summarizes the future principal payments due at maturity on senior long-term debt and other debt as of December 31, 2010.

10. Shareholders’ Equity

a) The Company had 50,000,000 shares of no par value common stock authorized of which 9,717,928 shares and 9,819,151 shares were issued and outstanding at December 31, 2010 and 2009, respectively. The Company also has 10,000,000 shares of no par value preferred stock authorized, none of which were issued or outstanding at December 31, 2010 or 2009.

In November 2010, the Company’s Board of Directors approved the repurchase of up to $200 million of common stock under a share repurchase program (the Program). Under the Program, the Company may repurchase outstanding shares of common stock from time to time, primarily through open-market transactions. The Program has no expiration date but may be terminated by the Board of Directors at any time. This repurchase program replaced a previous repurchase program that had been approved by the Board of Directors in August 2005. As of December 31, 2010, the Company had repurchased 7,956 shares of common stock at a cost of $2.8 million under the Program. As of December 31, 2010, the Company had repurchased 484,750 shares of common stock at a cost of $178.7 million under the previous program, which was terminated upon approval of the Program.

b) Net income (loss) per share is determined by dividing net income (loss) to shareholders by the applicable weighted average shares outstanding.

	Years Ended December 31,
(in thousands, except per share amounts)	2010		2009		2008
Net income (loss) to shareholders	$	266,793	$	201,638	$	(58,767	)

Diluted net income (loss) per share	$	27.27	$	20.52	$	(5.95	)

Average closing common stock market prices are used to calculate the dilutive effect attributable to restricted stock.

Diluted shares outstanding for 2008 excluded 15,376 dilutive potential shares. These shares were excluded due to their antidilutive effect as a result of the Company’s net loss to shareholders for the year ended December 31, 2008.

c) The Company’s Employee Stock Purchase and Bonus Plan provides a method for employees and directors to purchase shares of the Company’s common stock on the open market. The plan encourages share ownership by providing for the award of bonus shares to participants equal to 10% of the net increase in the number of shares owned under the plan in a given year, excluding shares acquired through the plan’s loan program component. Under the loan program, the Company offers subsidized unsecured loans so participants may purchase shares and awards bonus shares equal to 5% of the shares purchased with a loan. The Company has authorized 100,000 shares for purchase under this plan, of which 60,931 and 70,874 shares were available for purchase at December 31, 2010 and 2009, respectively. At December 31, 2010 and 2009, loans outstanding under the plan, which are included in receivables on the consolidated balance sheets, totaled $13.7 million and $15.8 million, respectively.

d) The Markel Corporation Omnibus Incentive Plan (Omnibus Incentive Plan) provides for grants or awards of cash, restricted stock, restricted stock units, performance grants and other stock-based awards to employees and directors. The Omnibus Incentive Plan is administered by the Compensation Committee of the Company’s Board of Directors (Compensation Committee) and will terminate on March 5, 2013. At December 31, 2010, there were 128,834 shares reserved for issuance under the Omnibus Incentive Plan.

Restricted stock units are awarded to certain associates and executive officers based upon meeting performance conditions determined by the Compensation Committee. These awards generally vest at the end of the fifth year following the year for which the Compensation Committee determines performance conditions have been met. At the end of the vesting period, recipients are entitled to receive one share of the Company’s common stock for each vested restricted stock unit. During 2010, the Company awarded 3,186 restricted stock units to certain associates and executive officers based either on performance conditions being met or as an incentive to certain newly hired associates.

During 2010, the Company awarded 1,561 shares of restricted stock to its non-employee directors. The shares awarded to non-employee directors will vest in 2011.

10. Shareholders’ Equity (continued)

In May 2010, the Compensation Committee awarded 26,410 restricted stock units to certain associates and executive officers to assist the Company in retaining the services of key employees. These restricted stock units had a grant-date fair value of $9.5 million. Each restricted stock unit will ultimately allow the recipient to receive one share of the Company’s common stock. Twenty percent of the restricted stock units vest after one year, and the balance after five years, with pro rata vesting in case of death, disability or retirement. Shares will be issued in respect of the initial twenty percent of the restricted stock units promptly after vesting. The remaining shares will be issued only following termination of employment, except that issuance of a portion of the shares may occur earlier if designated share price targets are attained. Violation of non-competition agreements contained in the award agreement may result in cancellation of the award, even after vesting.

The following table summarizes nonvested share-based awards.

	Number of Awards			Weighted Average Grant-Date Fair Value
Nonvested awards at January 1, 2010		23,855		$	415.39
Granted		31,157			358.48
Vested		(4,579	)		309.44
Forfeited		(5,509	)		433.00
Nonvested awards at December 31, 2010		44,924		$	384.54

The fair value of the Company’s share-based awards is determined based on the average price of the Company’s common shares on the grant date. The weighted average grant-date fair value of the Company’s share-based awards granted in 2010, 2009 and 2008 was $358.48, $275.93 and $461.65, respectively. As of December 31, 2010, unrecognized compensation cost related to nonvested share-based awards was $10.6 million, which is expected to be recognized over a weighted average period of 3.7 years. The fair value of the Company’s share-based awards that vested during 2010, 2009 and 2008 was $1.4 million, $2.6 million and $2.1 million, respectively.

e) In connection with the acquisition of Aspen, the Company provided for the conversion of options issued under the Aspen Holdings, Inc. 2008 Stock Option Plan and the Aspen Holdings, Inc. 2008 Stock Option Plan for Non-Employee Directors (the Aspen Option Plans) into options to purchase 58,116 of the Company’s common shares. No further options are available for issuance under the Aspen Option Plans. The options issued were fully vested and exercisable upon conversion and expire ten years from the original date of issue or sooner upon the recipient’s termination of employment or death. The options issued had a weighted average exercise price of $225.94 and a grant-date fair value of $157.15. The fair value of the options was estimated on the grant date using the Black-Scholes option pricing model. Assumptions used in the pricing model included an expected annual volatility of 35%, a risk-free rate of approximately 1% and an expected term of four years. The expected annual volatility was based on the historical volatility of the Company’s stock and other factors. The risk-free rate was based on the U.S. Treasury yield curve, with a remaining term equal to the expected life assumption at the grant date. The expected term of the options granted represents the period of time that the options were expected to be outstanding at the grant date. Historical data was used to estimate option exercises and employee termination within the pricing model.

During 2010, 7,595 options were exercised under the Aspen Option Plans, resulting in cash proceeds of $1.5 million and a current tax benefit of $0.4 million. The intrinsic value of options exercised in 2010 was $1.3 million.

At December 31, 2010, there were 50,521 options outstanding and exercisable under the Aspen Option Plans with a weighted average exercise price of $229.80 and a weighted average remaining contractual life of seven years. The outstanding options had an intrinsic value of $7.4 million at December 31, 2010.

12. 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 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.

Markel Corporation & Subsidiaries

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

12. Fair Value Measurements (continued)

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.

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 for fixed maturities, 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.

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, residential mortgage-backed securities and corporate debt securities.

Derivatives. Derivatives are recorded at fair value on a recurring basis and include a credit default swap. The fair value of the credit default swap is measured by the Company using a third party pricing model. See note 20 for a discussion of the valuation model for the credit default swap, including the key inputs and assumptions to the model. Due to the significance of unobservable inputs required in measuring the fair value of the credit default swap, the credit default swap has been classified as Level 3 within the fair value hierarchy.

12. Fair Value Measurements (continued)

There were no transfers into or out of Level 1 and Level 2 during 2010 and 2009. The Company did not have any assets or liabilities measured at fair value on a non-recurring basis during the year ended December 31, 2010. At December 31, 2010, the Company did not hold material investments in auction rate securities, loans held for sale or mortgage-backed securities backed by subprime or Alt-A collateral.

13. Reinsurance

The Company purchases reinsurance in order to reduce its retention on individual risks and enable it to underwrite policies with sufficient limits to meet policyholder needs. In a reinsurance transaction, an insurance company transfers, or cedes, all or part of its exposure in return for a portion of the premium. The ceding of insurance does not legally discharge the Company from its primary liability for the full amount of the policies, and the Company will be required to pay the loss and bear collection risk if the reinsurer fails to meet its obligations under the reinsurance agreement.

A credit risk exists with reinsurance ceded to the extent that any reinsurer is unable to meet the obligations assumed under the reinsurance agreements. Allowances are established for amounts deemed uncollectible. The Company evaluates the financial condition of its reinsurers and monitors concentration of credit risk arising from its exposure to individual reinsurers. At December 31, 2010 and 2009, balances recoverable from the Company’s ten largest reinsurers, by group, represented approximately 68% and 62%, respectively, of the reinsurance recoverable on paid and unpaid losses, before considering reinsurance allowances. At December 31, 2010, the Company’s largest reinsurance balance was due from the Munich Re Group and represented 16% of the reinsurance recoverable on paid and unpaid losses, before considering reinsurance allowances.

To further reduce credit exposure to reinsurance recoverable balances, the Company has received collateral, including letters of credit and trust accounts, from certain reinsurers. Collateral related to these reinsurance agreements is available, without restriction, when the Company pays losses covered by the reinsurance agreements.

The following table summarizes the Company’s reinsurance allowance for doubtful accounts.

	Years Ended December 31,
(dollars in thousands)	2010			2009			2008
REINSURANCE ALLOWANCE, BEGINNING OF YEAR	$	151,339		$	155,882		$	167,465
Additions:

REINSURANCE ALLOWANCE, END OF YEAR	$	155,190		$	151,339		$	155,882

Management believes the Company’s reinsurance allowance for doubtful accounts is adequate at December 31, 2010; however, the deterioration in the credit quality of existing reinsurers or disputes over reinsurance agreements could result in additional charges.

The year ended December 31, 2010 included $43.2 million of estimated reinsurance recoverables related to the Deepwater Horizon drilling rig explosion. Ceded incurred losses and loss adjustment expenses in 2008 included ceded losses on the 2008 Hurricanes of $58.6 million.

The percentage of assumed earned premiums to net earned premiums was 15%, 12% and 10% for the years ended December 31, 2010, 2009 and 2008, respectively.

16. Statutory Financial Information

a) The following table includes unaudited selected information for the Company’s wholly-owned domestic insurance subsidiaries as filed with state insurance regulatory authorities.

	Years Ended December 31,
(dollars in thousands)	2010		2009		2008
Net income (loss)	$	165,605	$	129,035	$	(19,073	)
Statutory capital and surplus	$	1,503,165	$	1,308,437	$	985,675

The laws of the domicile states of the Company’s domestic insurance subsidiaries govern the amount of dividends that may be paid to the Company. Generally, statutes in the domicile states of the Company’s domestic insurance subsidiaries require prior approval for payment of extraordinary as opposed to ordinary dividends. At December 31, 2010, the Company’s domestic insurance subsidiaries could pay up to $197.0 million during the following 12 months under the ordinary dividend regulations.

In converting from statutory accounting principles to U.S. GAAP, typical adjustments include deferral of policy acquisition costs, differences in the calculation of deferred income taxes and the inclusion of net unrealized gains or losses relating to fixed maturities in shareholders’ equity. The Company does not use any permitted statutory accounting practices that are different from prescribed statutory accounting practices.

b) MIICL files an annual audited return with the Financial Services Authority (FSA) in the United Kingdom. Assets and liabilities reported within the annual FSA return are prepared subject to specified rules concerning valuation and admissibility.

The following table summarizes MIICL’s FSA Return net income (loss) and policyholders’ surplus.

	Years Ended December 31,
(dollars in thousands)	2010(1)		2009		2008
Net income (loss)	$	82,984	$	80,193	$	(40,946	)
Policyholders’ surplus	$	522,325	$	382,741	$	264,421

⁽¹⁾ Estimated and unaudited.

MIICL’s ability to pay dividends is limited by applicable FSA requirements, which require MIICL to give 14 days advance notice to the FSA of its intention to declare and pay a dividend. In addition, MIICL must comply with the United Kingdom Companies Act of 2006, which provides that dividends may only be paid out of profits available for that purpose.

17. Segment Reporting Disclosures

The Company operates in three segments of the specialty insurance marketplace: the Excess and Surplus Lines, the Specialty Admitted and the London markets. The Company considers many factors, including the nature of its insurance products, production sources, distribution strategies and regulatory environment in determining how to aggregate operating segments.

All investing activities related to our insurance operations are included in the Investing segment. For purposes of segment reporting, the Other Insurance (Discontinued Lines) segment includes lines of business that have been discontinued in conjunction with an acquisition. The Company’s non-insurance operations primarily consist of controlling interests in various businesses. For purposes of segment reporting, the Company’s non-insurance operations are not considered to be a reportable operating segment.

Segment profit or loss for each of the Company’s operating 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 (loss) or net income (loss) computed in accordance with U.S. GAAP as a measure of profitability. Underwriting profit or loss provides a basis for management to evaluate the Company’s underwriting performance. Segment profit for the Investing segment is measured by net investment income and net realized investment gains or losses.

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 assets are not allocated to the Excess and Surplus Lines, Specialty Admitted, London Insurance Market or Other Insurance (Discontinued Lines) segments since the Company does not manage its assets by operating segment. Invested assets related to our insurance operations are allocated to the Investing segment since these assets are available for payment of losses and expenses for all operating segments. The Company does not allocate capital expenditures for long-lived assets to any of its operating segments for management reporting purposes.

a) The Company maintains defined contribution plans for employees of its United States insurance operations in accordance with Section 401(k) of the Internal Revenue Code. Employees of the Company’s non-insurance subsidiaries are provided post-retirement benefits under separate plans. The Company also provides another defined contribution plan for Markel International employees. This plan is in line with local market terms and conditions of employment. Expenses relating to the Company’s defined contribution plans were $14.4 million, $13.1 million and $13.1 million in 2010, 2009 and 2008, respectively.

18. Employee Benefit Plans (continued)

b) The Terra Nova Pension Plan is a defined benefit plan which covers Markel International employees who meet the eligibility conditions set out in the plan. The plan has been closed to new participants since 2001. The cost of providing pensions for employees is charged to earnings over the average working life of employees according to actuarial recommendations. Final benefits are based on the employee’s years of credited service and the higher of pensionable compensation received in the calendar year preceding retirement or the best average pensionable compensation received in any three consecutive years in the ten years preceding retirement. The Company uses December 31 as the measurement date for the Terra Nova Pension Plan.

The following table summarizes the components of net periodic benefit cost and the weighted average assumptions for the Terra Nova Pension Plan.

Expected return on plan assets		(8,645	)		(6,877	)		(7,208	)
Amortization of net actuarial pension loss		1,931			1,990			1,602
NET PERIODIC BENEFIT COST	$	1,336		$	2,368		$	2,184
Weighted average assumptions as of December 31:
Discount rate		5.4	%		5.8	%		6.0	%
Expected return on plan assets		6.8	%		7.2	%		7.2	%
Rate of compensation increase		4.5	%		4.5	%		4.5	%

The projected benefit obligation and the net periodic benefit cost are determined by independent actuaries using assumptions provided by the Company. In determining the discount rate, the Company uses the current yield on high-quality, fixed-income investments that have maturities corresponding to the anticipated timing of estimated defined benefit payments. The Company’s discount rate approximates a bond yield from a published index that includes “AA” rated corporate bonds with maturities of 15 years or more. The expected return on plan assets is estimated based upon the anticipated average yield on plan assets and reflects expected changes in the allocation of plan assets. Asset returns reflect management’s belief that 4.5% is a reasonable rate of return to anticipate for fixed maturities given current market conditions and future expectations. In addition, the expected return on plan assets includes an assumption that equity securities will outperform fixed maturities by approximately 3.5% over the long term. The rate of compensation increase is based upon historical experience and management’s expectation of future compensation.

Management’s discount rate and rate of compensation increase assumptions at December 31, 2010 were used to calculate the Company’s projected benefit obligation. Management’s discount rate, expected return on plan assets and rate of compensation increase assumptions at December 31, 2009 were used to calculate the net periodic benefit cost for 2010. The Company estimates that net periodic benefit cost in 2011 will include an expense of $1.8 million resulting from the amortization of the net actuarial pension loss included as a component of accumulated other comprehensive income at December 31, 2010.

The fair values of each of the plan’s assets are measured using quoted prices in active markets for identical assets, which represent Level 1 inputs within the fair value hierarchy established in FASB ASC 820-10. The following table summarizes the fair value of plan assets as of December 31, 2010 and 2009.

TOTAL	$	134,589	$	120,092

18. Employee Benefit Plans (continued)

The Company’s target asset allocation for the plan is 73% equity securities and 27% fixed maturities. At December 31, 2010, the actual allocation of assets in the plan was 77% equity securities and 23% fixed maturities. At December 31, 2009, the actual allocation of plan assets was 80% equity securities and 20% fixed maturities.

Investments are managed by a third-party investment manager. Equity securities are invested in two index funds that are allocated 67% to shares of United Kingdom companies and 33% to companies in other markets. The primary objective of investing in these funds is to earn rates of return that are consistently in excess of inflation. Investing in equity securities, historically, has provided rates of return that are higher than investments in fixed maturities. As the Company’s obligations under this pension plan are expected to be paid out over a period in excess of thirty years, the Company primarily invests in equity securities. Fixed maturity investments are allocated between five index funds, two that include United Kingdom government securities, one that includes securities issued by other foreign governments and two that include United Kingdom corporate securities. The assets in these funds are invested to meet the Company’s obligations for current pensioners and those individuals nearing retirement. The plan does not invest in the Company’s common shares.

At December 31, 2010 and 2009, the fair value of plan assets exceeded the plan’s accumulated benefit obligation of $109.8 million and $105.8 million, respectively. The Company expects to make plan contributions of $6.5 million in 2011.

The benefits expected to be paid in each year from 2011 to 2015 are $2.8 million, $2.9 million, $3.0 million, $3.1 million and $3.2 million, respectively. The aggregate benefits expected to be paid in the five years from 2016 to 2020 are $17.3 million. The expected benefits to be paid are based on the same assumptions used to measure the Company’s projected benefit obligation at December 31, 2010 and include estimated future employee service.

20. Derivatives

The Company is a party to a credit default swap agreement, under which third party credit risk is transferred from a counterparty to the Company. The Company entered into the credit default swap agreement for investment purposes. At both December 31, 2010 and 2009, the notional amount of the credit default swap was $33.1 million, which represented the Company’s aggregate exposure to losses if specified credit events involving third party reference entities occur. These third party reference entities are specified under the terms of the agreement and represent a portfolio of names upon which the Company has assumed credit risk from the counterparty. The Company’s exposure to loss from any one reference entity is limited to $20.0 million. The credit default swap has a scheduled termination date of December 2014.

80  |

20. Derivatives (continued)

The credit default swap is accounted for as a derivative instrument and is recorded at fair value with any changes in fair value recorded in net investment income. At December 31, 2010 and 2009, the credit default swap had a fair value of $25.2 million and $27.0 million, respectively. The fair value of the credit default swap is determined by the Company using an external valuation model that is dependent upon several inputs, including changes in interest rates, credit spreads, expected default rates, changes in credit quality, future expected recovery rates and other market factors. The fair value of the credit default swap is included in other liabilities on the consolidated balance sheets. Net investment income in 2010 and 2009 included a favorable change in the fair value of the credit default swap of $1.7 million and $3.0 million, respectively. Net investment income in 2008 included an adverse change in the fair value of the credit default swap of $13.7 million.

Since entering into the credit default swap agreement, the Company has paid $16.9 million to settle its obligations related to credit events. These payments reduced the Company’s liability related to its credit default swap.

See notes 2(i) and 12 for further discussion of the Company’s credit default swap.

The Company had no other material derivative instruments at December 31, 2010.

21. Acquisitions

a) Insurance Acquisition. On October 15, 2010, the Company completed its acquisition of 100% of the outstanding shares of Aspen, a Nebraska-based privately held corporation whose FirstComp insurance group provides workers’ compensation insurance and related services, principally to small businesses, in 31 states. This acquisition will provide the Company with the ability to expand its insurance operations to include workers’ compensation coverage. Results attributable to this acquisition are included in the Specialty Admitted segment.

FirstComp operations collectively produced approximately $290 million of gross written premiums in 2010. A portion of the business FirstComp produces is written on FirstComp Insurance Company, a wholly-owned subsidiary and a Nebraska-domiciled insurance company. FirstComp also produces business for unaffiliated insurance companies through FirstComp Underwriters Group, Inc. and FirstComp Insurance Agency, Inc., which act as managing general agents. During 2010, the Specialty Admitted segment included $40.7 million of gross written premiums produced by FirstComp. The Company expects to significantly increase its share of the premium writings produced by FirstComp in 2011.

Total consideration for this acquisition was $135.6 million, which included cash consideration of $128.9 million. As part of the consideration, outstanding options to purchase shares of Aspen’s common stock were converted into options to purchase 58,116 shares of the Company’s common stock at an average exercise price of $225.94 per share. These options had a fair value at acquisition of $6.7 million, net of taxes. Aspen shareholders also received contingent value rights that may result in the payment of additional cash consideration depending, among other things, upon the development of FirstComp’s loss reserves and loss sensitive profit commissions over time. Based on current expectations, the Company believes that it is unlikely that any contingent consideration will be paid related to the contingent value rights.

The purchase price was allocated to the acquired assets and liabilities of Aspen based on estimated fair values at the acquisition date. The Company recognized goodwill of $67.2 million, which is primarily attributable to synergies that are expected to result upon integration of FirstComp into the Company’s insurance operations. None of the goodwill recognized is expected to be deductible for income tax purposes. The Company also recognized other intangible assets of $70.0 million.

The following table presents, on a pro forma basis, the Company’s unaudited consolidated operating revenues and net income to shareholders as if the acquisition of Aspen had occurred on January 1, 2009 and after certain adjustments, primarily related to amortization of intangible assets, interest expense on debt retired at acquisition and the corresponding income tax effects. The pro forma financial information does not necessarily reflect the results that would have occurred had the acquisition taken place on

January 1, 2009.

Operating revenues	$	2,361,174	$	2,263,321
Net income to shareholders	$	243,795	$	193,729

b) Non-insurance Acquisitions. On May 11, 2010, the Company acquired Solbern, Inc., a privately held company headquartered in Fairfield, New Jersey that manufactures food processing equipment for both domestic and international markets. On December 15, 2010, the Company acquired a 60% controlling interest in RD Holdings, LLC (RetailData), a privately held company headquartered in Richmond, Virginia that provides retail intelligence services. On December 23, 2010, the Company acquired a 75% controlling interest in Diamond Healthcare Corporation (Diamond Healthcare), a privately held company headquartered in Richmond, Virginia that manages behavioral health programs throughout the United States. Under the terms of the acquisition agreements, the Company has the option to acquire the remaining equity interests in RetailData and Diamond Healthcare in the future. Any additional consideration for the remaining equity interests would be based on the future earnings of these companies. Also during 2010, ParkLand Ventures, Inc., a subsidiary that owns and operates manufactured housing communities throughout the United States, made several acquisitions.

Total consideration for the Company’s non-insurance acquisitions in 2010 was approximately $132 million. Since the Company consolidates its non-insurance operations on a one-month lag, the purchase price allocation for RetailData and Diamond Healthcare will be completed in the first quarter of 2011. At December 31, 2010, amounts related to the consideration paid to acquire RetailData and Diamond Healthcare were included in other assets on the consolidated balance sheet. The Company recognized goodwill of $2.6 million and other intangible assets of $12.7 million in connection with the Solbern, Inc. and ParkLand Ventures, Inc. acquisitions completed in 2010.

The Company’s strategy in acquiring controlling interests in businesses that operate outside of the specialty insurance marketplace is similar to the Company’s strategy for purchasing equity securities. The Company seeks to invest in profitable companies, with honest and talented management, that exhibit reinvestment opportunities and capital discipline, at reasonable prices.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders

Markel Corporation:

We have audited the accompanying consolidated balance sheets of Markel Corporation and subsidiaries (the Company) as of December 31, 2010 and 2009, and the related consolidated statements of operations and comprehensive income (loss), changes in equity, and cash flows for each of the years in the three-year period ended December 31, 2010. These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Markel Corporation and subsidiaries as of December 31, 2010 and 2009, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2010, in conformity with U.S. generally accepted accounting principles.

The Company adopted Financial Accounting Standards Board Accounting Standards Codification 320-10-65 related to the recognition and presentation of other-than-temporary impairment of investments on April 1, 2009.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Markel Corporation’s internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 28, 2011 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders

Markel Corporation:

We have audited Markel Corporation’s (the Company) internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (continued)

In our opinion, Markel Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control—Integrated Framework issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Markel Corporation and subsidiaries as of December 31, 2010 and 2009, and the related consolidated statements of operations and comprehensive income (loss), changes in equity, and cash flows for each of the years in the three-year period ended December 31, 2010, and our report dated February 28, 2011 expressed an unqualified opinion on those consolidated financial statements.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934. Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

Management does not expect that its internal control over financial reporting 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. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. 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. The design of any system of internal control over financial reporting 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.

Under the supervision and with the participation of management, including the Chief Executive Officer and the Chief Financial Officer, we evaluated the effectiveness of our internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation, we have concluded that we maintained effective internal control over financial reporting as of December 31, 2010.

KPMG LLP, our independent registered public accounting firm, has issued an attestation report on the effectiveness of the Company’s internal control over financial reporting, which is included herein.

MANAGEMENT’S DISCUSSION & ANALYSIS

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Critical Accounting Estimates

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 all subsidiaries. For a discussion of our significant accounting policies, see note 1 of the notes to consolidated financial statements.

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 our critical accounting estimates and assumptions quarterly. These reviews include evaluating the adequacy of reserves for unpaid losses and loss adjustment expenses, the reinsurance allowance for doubtful accounts and income tax liabilities, as well as analyzing the recoverability of deferred tax assets, assessing goodwill for impairment and evaluating the investment portfolio for other-than-temporary declines in estimated fair value. Actual results may differ materially from the estimates and assumptions used in preparing the consolidated financial statements.

Unpaid Losses and Loss Adjustment Expenses

Our consolidated balance sheet included estimated unpaid losses and loss adjustment expenses of $5.4 billion and reinsurance recoverable on unpaid losses of $0.8 billion at December 31, 2010 compared to $5.4 billion and $0.9 billion, respectively, at December 31, 2009. We do not discount our reserves for losses and loss adjustment expenses to reflect estimated present value.

We accrue liabilities for unpaid losses and loss adjustment expenses based upon estimates of the ultimate amounts payable. We maintain reserves for specific claims incurred and reported (case reserves) and reserves for claims incurred but not reported (IBNR reserves).

Reported claims are in various stages of the settlement process, and the corresponding reserves for reported claims are based primarily on case-by-case evaluations of the individual claims. Case reserves consider our estimate of the ultimate cost to settle the claims, including investigation and defense of lawsuits resulting from the claims, and may be subject to adjustment for differences between costs originally estimated and costs subsequently re-estimated or incurred. Each claim is settled individually based upon its merits, and some claims may take years to settle, especially if legal action is involved.

As of any balance sheet date, all claims have not yet been reported, and some claims may not be reported for many years. As a result, the liability for unpaid losses and loss adjustment expenses includes significant estimates for incurred but not reported claims.

U.S. GAAP requires that IBNR reserves be based on the estimated ultimate cost of settling claims, including the effects of inflation and other social and economic factors, using past experience adjusted for current trends and any other factors that would modify past experience. IBNR reserves are generally calculated by subtracting paid losses and case reserves from estimated ultimate losses. IBNR reserves were 61% of total unpaid losses and loss adjustment expenses at December 31, 2010 compared to 60% at December 31, 2009.

88  |

Our liabilities for unpaid losses and loss adjustment expenses can generally be categorized into two distinct groups, short-tail business and long-tail business. Short-tail business refers to lines of business, such as property, accident and health, motorcycle, watercraft and marine hull exposures for which losses are usually known and paid shortly after the loss actually occurs. Long-tail business describes lines of business for which specific losses may not be known and reported for some period and losses take much longer to emerge. Given the time frame over which long-tail exposures are ultimately settled, there is greater uncertainty and volatility in these lines than in short-tail lines of business. Our long-tail coverages consist of most casualty lines, including professional liability, directors’ and officers’ liability, products liability, general liability and excess and umbrella exposures, as well as workers’ compensation insurance. Some factors that contribute to the uncertainty and volatility of long-tail casualty programs, and thus require a significant degree of judgment in the reserving process, include the inherent uncertainty as to the length of reporting and payment development patterns, the possibility of judicial interpretations or legislative changes that might impact future loss experience relative to prior loss experience and the potential lack of comparability of the underlying data used in performing loss reserve analyses.

Our ultimate liability may be greater or less than current reserves. Changes in our estimated ultimate liability for loss reserves generally occur as the result of the emergence of unanticipated loss activity, the completion of specific actuarial or claims studies or changes in internal or external factors. We closely monitor new information on reported claims and use statistical analyses prepared by our actuaries to evaluate the adequacy of our recorded reserves. We are required to exercise considerable judgment when assessing the relative credibility of loss development trends. Our philosophy is to establish loss reserves that are more likely redundant than deficient. This means that we seek to establish loss reserves that will ultimately prove to be adequate. As a result, if new information or trends indicate an increase in frequency or severity of claims in excess of what we initially anticipated, we generally respond quickly and increase loss reserves. If, however, frequency or severity trends are more favorable than initially anticipated, we often wait to reduce our loss reserves until we can evaluate experience in additional periods to confirm the credibility of the trend. In addition, for long-tail lines of business, trends develop over longer periods of time, and as a result, we give credibility to these trends more slowly than for short-tail or less volatile lines of business.

Each quarter, our actuaries prepare estimates of the ultimate liability for unpaid losses and loss adjustment expenses based on established actuarial methods. Management reviews these estimates, supplements the actuarial analyses with information provided by claims, underwriting and other operational personnel and determines its best estimate of loss reserves, which is recorded in our financial statements. Our procedures for determining the adequacy of loss reserves at the end of the year are substantially similar to the procedures applied at the end of each interim period.

Additionally, once a year, generally during the third quarter, we conduct a detailed review of our liability for unpaid losses and loss adjustment expenses for asbestos and environmental (A&E) claims. If there is significant development on A&E claims in advance of the annual review, such development is considered by our actuaries and by management as part of our quarterly review process. We consider a detailed annual review appropriate because A&E claims develop slowly, are typically reported and paid many years after the loss event occurs and, historically, have exhibited a high degree of variability.

Any adjustments resulting from our interim or year-end reviews, including changes in estimates, are recorded as a component of losses and loss adjustment expenses in the period of the change. Reserve changes that increase previous estimates of ultimate claims cost are referred to as unfavorable or adverse development, deficiencies or reserve strengthening. Reserve changes that decrease previous estimates of ultimate claims cost are referred to as favorable development or redundancies.

MANAGEMENT’S DISCUSSION & ANALYSIS

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

In establishing our liabilities for unpaid losses and loss adjustment expenses, our actuaries estimate an ultimate loss ratio, by accident year, for each of our over 100 product lines with input from our underwriting and claims associates. In estimating an ultimate loss ratio for a particular line of business, our actuaries may use one or more actuarial reserving methods and select from these a single point estimate. To varying degrees, these methods include detailed statistical analysis of past claim reporting, settlement activity, claim frequency and severity, policyholder loss experience, industry loss experience and changes in market conditions, policy forms and exposures. The actuarial methods we use include:

Paid Loss Development – This method uses historical loss payment patterns to estimate future loss payment patterns. Our actuaries use the historical loss patterns to develop factors that are applied to current paid loss amounts to calculate expected ultimate losses.

Incurred Loss Development – This method uses historical loss reporting patterns to estimate future loss reporting patterns. Our actuaries use the historical loss patterns to develop factors that are applied to current reported losses to calculate expected ultimate losses.

Bornhuetter-Ferguson Paid Loss Development – This method divides the projection of ultimate losses into the portion that has already been paid and the portion that has yet to be paid. The portion that has yet to be paid is estimated as the product of three amounts: the premium earned for the exposure period, the expected loss ratio and the percentage of ultimate losses that are still unpaid. The expected loss ratio is selected by considering historical loss ratios, adjusted for any known changes in pricing, loss trends, adequacy of case reserves, changes in administrative practices and other relevant factors.

Bornhuetter-Ferguson Incurred Loss Development – This method is identical to the Bornhuetter-Ferguson paid loss development method, except that it uses the percentage of ultimate losses that are still unreported, instead of the percentage of ultimate losses that are still unpaid.

Frequency/Severity – Under this method, expected ultimate losses are equal to the product of the expected ultimate number of claims and the expected ultimate average cost per claim. Our actuaries use historical reporting patterns and severity patterns to develop factors that are applied to the current reported amounts to calculate expected ultimate losses.

Each actuarial method has its own set of assumptions and its own strengths and limitations, with no one method being better than the others in all situations. Our actuaries select the reserving methods that they believe will produce the most reliable estimate for the class of business being evaluated. Greater judgment may be required when we introduce new product lines or when there have been changes in claims handling practices, as the statistical data available may be insufficient. In these instances, we may rely upon assumptions applied to similar lines of business, rely more heavily on industry experience, take into account changes in underwriting guidelines and risk selection or review the impact of changes in claims reserving practices with claims personnel. For example, in 2009, as part of the formation of a shared service claims function, we reassigned certain claims handling responsibilities to different claims personnel based upon our product line groupings and regional office model, and we standardized certain claims handling practices. We believe these changes in claims handling practices impacted the comparability of case reserves between periods. Our actuaries considered these changes and made adjustments to data where appropriate when establishing their actuarial point estimates.

A key assumption in most actuarial analyses is that past development patterns will repeat themselves in the future, absent a significant change in internal or external factors that influence the ultimate cost of our unpaid losses and loss adjustment expenses. Our estimates reflect implicit

90  |

and explicit assumptions regarding the potential effects of external factors, including economic and social inflation, judicial decisions, law changes, general economic conditions and recent trends in these factors. Our actuarial analyses are based on statistical analysis but also consist of reviewing internal factors that are difficult to analyze statistically, including underwriting and claims handling changes. In some of our markets, and where we act as a reinsurer, the timing and amount of information reported about underlying claims are in the control of third parties. This can also affect estimates and require re-estimation as new information becomes available.

As indicated above, we may use one or more actuarial reserving methods, which incorporate numerous underlying judgments and assumptions, to establish our estimate of ultimate loss reserves. While we use our best judgment in establishing our estimate for loss reserves, applying different assumptions and variables could lead to significantly different loss reserve estimates.

Loss frequency and loss severity are two key measures of loss activity that often result in adjustments to actuarial assumptions relative to ultimate loss reserve estimates. Loss frequency measures the number of claims per unit of insured exposure. When the number of newly reported claims is higher than anticipated, generally speaking, loss reserves are increased. Conversely, loss reserves are generally decreased when fewer claims are reported than expected. Loss severity measures the average size of a claim. When the average severity of reported claims is higher than originally estimated, loss reserves are typically increased. When the average claim size is lower than anticipated, loss reserves are typically decreased. For example, in each of the past three years, we have experienced redundancies on prior years’ loss reserves in our professional and products liability lines as a result of decreases in loss severity, while over the past three-year period we have experienced deficiencies on prior years’ loss reserves related to our A&E exposures as a result of increases in loss frequency and severity.

Changes in prior years’ loss reserves, including the trends and factors that impacted loss reserve development, as well as the likelihood that such trends and factors could result in future loss reserve development, are discussed in further detail under “Results of Operations.”

Loss reserves are established for each of our product lines at management’s best estimate, which is generally higher than the corresponding actuarially calculated point estimate. The actuarial point estimate represents our actuaries’ estimate of the most likely amount that will ultimately be paid to settle the loss reserves we have recorded at a particular point in time; however, there is inherent uncertainty in the point estimate as it is the expected value in a range of possible reserve estimates. In some cases, actuarial analyses, which are based on statistical analysis, cannot fully incorporate all of the subjective factors that affect development of losses. In other cases, management’s perspective of these more subjective factors may differ from the actuarial perspective. Subjective factors where management’s perspective may differ from that of the actuaries include: the credibility and timeliness of claims information received from third parties, economic and social inflation, judicial decisions, law changes, changes in underwriting or claims handling practices, general economic conditions, the risk of moral hazard and other current and developing trends within the insurance market, including the effects of competition. As a result, the actuarially calculated point estimates for each of our lines of business represent starting points for management’s quarterly review of loss reserves.

Management’s best estimate of net reserves for unpaid losses and loss adjustment expenses exceeded the actuarially calculated point estimate by $361 million, or 8.5%, at December 31, 2010, compared to $371 million, or 8.9%, at December 31, 2009. In management’s opinion, the actuarially calculated point estimate generally underestimates both the ultimate favorable impact of a hard insurance market and the ultimate adverse impact of a soft insurance market. Therefore, the percentage by which management’s best estimate exceeds the actuarial point estimate will generally be higher during a soft market than during a hard market.

MANAGEMENT’S DISCUSSION & ANALYSIS

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

The difference between management’s best estimate and the actuarially calculated point estimate in both 2010 and 2009 is primarily associated with our long-tail business in the Excess and Surplus Lines and London Insurance Market segments. In both 2010 and 2009, management’s best estimate exceeded the actuarial point estimate as a result of attributing less credibility than our actuaries to favorable trends experienced on our long-tail lines of business in recent years. In particular, given the long-tail and volatile nature of the business in the London Insurance Market segment, as well as past unfavorable development in this segment, management has not incorporated these favorable trends into its best estimate to the same extent as the actuaries. Management also believes that the actuaries’ point estimates for the 2008 to 2010 accident years do not fully reflect the impact of soft insurance market conditions or the recent economic environment. During a recessionary environment, the frequency of insurance claims may increase. Similarly, the risk that an insured will intentionally cause or be indifferent to a loss may increase during an economic downturn, and the attention to loss prevention measures may decrease. These subjective factors affect the development of losses and represent instances where management’s perspectives may differ from those of our actuaries.

Management also considers the range, or variability, of reasonably possible losses determined by our actuaries when establishing its best estimate for loss reserves. The actuarial ranges represent our actuaries’ estimate of a likely lowest amount and highest amount that will ultimately be paid to settle the loss reserves we have recorded at a particular point in time. The range determinations are based on estimates and actuarial judgments and are intended to encompass reasonably likely changes in one or more of the factors that were used to determine the point estimates. Using statistical models, our actuaries establish high and low ends of a range of reasonable reserve estimates for each of our operating segments.

The following table summarizes our reserves for net unpaid losses and loss adjustment expenses and the actuarially established high and low ends of a range of reasonable reserve estimates, by segment, at December 31, 2010.

(dollars in millions)	Net Loss Reserves  Held		Low End  of Actuarial Range(1)		High End of Actuarial Range(1)
Excess and Surplus Lines	$	2,113.2	$	1,711.0	$	2,373.3
Specialty Admitted		550.0		451.0		603.3
London Insurance Market		1,513.0		1,136.7		1,552.6
Other Insurance (Discontinued Lines)		424.1		212.9		948.5

⁽¹⁾ Due to the actuarial methods used to determine the separate ranges for each segment of our business, it is not appropriate to aggregate the high or low ends of the separate ranges to determine the high and low ends of the actuarial range on a consolidated basis.

Undue reliance should not be placed on these ranges of estimates as they are only one of many points of reference used by management to determine its best estimate of ultimate losses. Further, actuarial ranges may not be a true reflection of the potential variability between loss reserves estimated at the balance sheet date and the ultimate cost of settling claims. Actuarial ranges are developed based on known events as of the valuation date, while ultimate losses are subject to events and circumstances that are unknown as of the valuation date. For example, the Claims and Reserves table on page 115, which provides a summary of historical development between originally estimated loss reserves and ultimate claims costs, illustrates this potential variability, reflecting a cumulative deficiency in net

92  |

reserves of 37% for the 2000 and prior accident years. A significant portion of the cumulative deficiency that occurred during those periods included adverse loss reserve development at Markel International, which we acquired in 2000. Historically, we have experienced greater volatility on acquired books of business than on existing books of business. The increases in pre-acquisition loss reserves at Markel International were primarily associated with books of business that were not subject to our underwriting discipline and that subsequently experienced unfavorable loss development that exceeded our initial expectations. We believe that as a result of applying greater underwriting discipline, including improved risk selection and pricing, on the business written since acquisition, total recorded loss reserves at Markel International are unlikely to vary to the same degree as we have experienced on the 2000 and prior accident years.

We place less reliance on the range established for our Other Insurance (Discontinued Lines) segment than on the ranges established for our remaining segments. The range established for our Other Insurance (Discontinued Lines) segment includes exposures related to acquired lines of business, many of which are no longer being written, that were not subject to our underwriting discipline and controls. Additionally, A&E exposures, which are subject to an uncertain and unfavorable legal environment, account for approximately 50% of the loss reserves considered in the range established for our Other Insurance (Discontinued Lines) segment.

Our exposure to A&E claims results from policies written by acquired insurance operations before their acquisitions. The exposure to A&E claims originated from umbrella, excess and commercial general liability (CGL) insurance policies and assumed reinsurance contracts that were written on an occurrence basis from the 1970s to mid-1980s. Exposure also originated from claims-made policies that were designed to cover environmental risks provided that all other terms and conditions of the policy were met. A&E claims include property damage and clean-up costs related to pollution, as well as personal injury allegedly arising from exposure to hazardous materials. After 1986, we began underwriting CGL coverage with pollution exclusions, and in some lines of business we began using a claims-made form. These changes significantly reduced our exposure to future A&E claims on post-1986 business.

There is significant judgment required in estimating the amount of our potential exposure from A&E claims due to the limited and variable historical data on A&E losses as compared to other types of claims, the potential significant reporting delays of claims from insureds to insurance companies and the continuing evolution of laws and judicial interpretations of those laws relative to A&E exposures. Due to these unique aspects of A&E exposures, the ultimate value of loss reserves for A&E claims cannot be estimated using traditional methods and is subject to greater uncertainty than other types of claims. Other factors contributing to the significant uncertainty in estimating A&E reserves include: uncertainty as to the number and identity of insureds with potential exposure; uncertainty as to the number of claims filed by exposed, but not ill, individuals; uncertainty as to the settlement values to be paid; difficulty in properly allocating responsibility and liability for the loss, especially if the claim involves multiple insurance providers or multiple policy periods; growth in the number and significance of bankruptcies of asbestos defendants; uncertainty as to the financial status of companies that insured or reinsured all or part of A&E claims; and inconsistent court decisions and interpretations with respect to underlying policy intent and coverage.

Due to these uncertainties, it is not possible to estimate our ultimate liability for A&E exposures with the same degree of reliability as with other types of exposures. Future development will be affected by the factors mentioned above and could have a material effect on our results of operations, cash flows and financial position. As of December 31, 2010, our consolidated balance sheet included estimated net reserves for A&E losses and loss adjustment expenses of $216.0 million. We seek to establish appropriate reserve levels for A&E exposures; however, these reserves could increase in the future. These reserves are not discounted to present value and are forecasted to pay out over the next 50 years.

MANAGEMENT’S DISCUSSION & ANALYSIS

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

Reinsurance Allowance for Doubtful Accounts

We evaluate and adjust reserves for uncollectible reinsurance based upon our collection experience, the financial condition of our reinsurers, collateral held and the development of our gross loss reserves. Our consolidated balance sheets at December 31, 2010 and 2009 included a reinsurance allowance for doubtful accounts of $155.2 million and $151.3 million, respectively.

Reinsurance recoverables recorded on insurance losses ceded under reinsurance contracts are subject to judgments and uncertainties similar to those involved in estimating gross loss reserves. In addition to these uncertainties, our reinsurance recoverables may prove uncollectible if the reinsurers are unable or unwilling to perform under the reinsurance contracts. In establishing our reinsurance allowance for amounts deemed uncollectible, we evaluate the financial condition of our reinsurers and monitor concentration of credit risk arising from our exposure to individual reinsurers. To determine if an allowance is necessary, we consider, among other factors, published financial information, reports from rating agencies, payment history, collateral held and our legal right to offset balances recoverable against balances we may owe. Our reinsurance allowance for doubtful accounts is subject to uncertainty and volatility due to the time lag involved in collecting amounts recoverable from reinsurers. Over the period of time that losses occur, reinsurers are billed and amounts are ultimately collected, economic conditions, as well as the operational and financial performance of particular reinsurers, may change and these changes may affect the reinsurers’ willingness and ability to meet their contractual obligation to us. It is also difficult to fully evaluate the impact of major catastrophic events on the financial stability of reinsurers, as well as the access to capital that reinsurers may have when such events occur. The ceding of insurance does not legally discharge us from our primary liability for the full amount of the policies, and we will be required to pay the loss and bear collection risk if the reinsurers fail to meet their obligations under the reinsurance contracts.

Income Taxes and Uncertain Tax Positions

The preparation of our consolidated income tax provision, including the evaluation of tax positions we have taken or expect to take on our income tax returns, requires significant judgment. In evaluating our tax positions, we recognize the tax benefit from an uncertain tax position only if, based on the technical merits of the position, it is more likely than not that the tax position will be sustained upon examination by the taxing authorities. Tax positions that meet the more likely than not threshold are then measured using a probability weighted approach, whereby the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement is recognized. The tax positions that we have taken or expect to take are based upon the application of tax laws and regulations, which are subject to interpretation, judgment and uncertainty. As a result, our actual liability for income taxes may differ significantly from our estimates.

We record deferred income taxes as assets or liabilities on our consolidated balance sheets to reflect the net tax effect of the temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and their respective tax bases. Deferred tax assets are reduced by a valuation allowance when management believes it is more likely than not that some, or all, of the deferred tax assets will not be realized. At December 31, 2010 and 2009, our net deferred tax asset was $63.3 million and $161.2 million, respectively. We did not have a valuation allowance on deferred tax assets at December 31, 2010 or 2009. The decrease in the net deferred tax asset in 2010 was due in part to an increase in the deferred tax liability related to accumulated other comprehensive income items resulting from an increase in net unrealized gains on investments during 2010. In evaluating our ability to realize the net deferred tax asset and assessing the need for a valuation allowance at December 31, 2010, we have made estimates regarding the future taxable income of our foreign subsidiaries and judgments about our ability to pursue prudent and feasible tax planning strategies. A change in any of these estimates and

94  |

judgments could result in the need to record a valuation allowance through a charge to earnings. See note 7 of the notes to consolidated financial statements for further discussion of our consolidated income tax provision, uncertain tax positions, net operating losses and valuation allowance.

Goodwill

Our consolidated balance sheet as of December 31, 2010 included goodwill from acquired businesses of $474.7 million. Goodwill is tested for impairment at least annually. We completed our annual test for impairment during the fourth quarter of 2010 based upon results of operations through September 30, 2010. There were no indications of goodwill impairment during 2010.

A significant amount of judgment is required in performing goodwill impairment tests. Such tests include estimating the fair value of our reporting units. We compare the estimated fair value of our reporting units to their respective carrying amounts including goodwill. The methods we use for estimating reporting unit fair values may include market quotations, asset and liability fair values and other valuation techniques, such as discounted cash flows and multiples of earnings or revenues. With the exception of market quotations, all of these methods involve significant estimates and assumptions.

Investments

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. All securities with unrealized losses are reviewed. For equity securities, a decline in fair value that is considered to be other-than-temporary is recognized in net income (loss) 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 we intend to sell the security or it is more likely than not that we 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 (loss) 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, we compare 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 (loss), 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.

We consider many factors in completing our 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 any anticipated recovery is considered. For fixed maturities, we consider whether we intend to sell the security or if it is more likely than not that we 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. When assessing whether we intend to sell a fixed maturity or if it is likely that we will be required to sell a fixed maturity before recovery of its amortized cost, we evaluate facts and circumstances including, but not limited to, decisions to reposition the investment portfolio, potential sales of investments to meet cash flow needs and potential sales of investments to capitalize on favorable pricing.

MANAGEMENT’S DISCUSSION & ANALYSIS

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

Risks and uncertainties are inherent in our other-than-temporary decline in fair value assessment methodology. The risks and uncertainties include, but are not limited to, incorrect or overly optimistic assumptions about the financial condition, liquidity or near-term prospects of an issuer, inadequacy of any underlying collateral, unfavorable changes in economic or social conditions and unfavorable changes in interest rates or credit ratings. Changes in any of these assumptions could result in charges to earnings in future periods.

Losses from write downs for other-than-temporary declines in the estimated fair value of investments, while potentially significant to net income (loss), do not have an impact on our financial position. Since our investment securities are considered available-for-sale and are recorded at estimated fair value, unrealized losses on investments are already included in accumulated other comprehensive income. See note 2(b) of the notes to consolidated financial statements for further discussion of our assessment methodology for other-than-temporary declines in the estimated fair value of investments.

Our Business

The following discussion and analysis should be read in conjunction with Selected Financial Data, the consolidated financial statements and related notes and the discussion under Risk Factors, “Critical Accounting Estimates” and “Safe Harbor and Cautionary Statement.”

We are a diverse financial holding company serving a variety of niche markets. Our principal business markets and underwrites specialty insurance products and programs. We believe that our specialty product focus and niche market strategy enable us to develop expertise and specialized market knowledge. We seek to differentiate ourselves from competitors by our expertise, service, continuity and other value-based considerations. We compete in three segments of the specialty insurance marketplace: the Excess and Surplus Lines, the Specialty Admitted and the London markets. We also own interests in various businesses that operate outside of the specialty insurance marketplace. Our financial goals are to earn consistent underwriting and operating profits and superior investment returns to build shareholder value.

Our Excess and Surplus Lines segment writes property and casualty insurance outside of the standard market for hard-to-place risks including catastrophe-exposed property, professional liability, products liability, general liability, commercial umbrella and other coverages tailored for unique exposures. At the beginning of 2008, our Excess and Surplus Lines segment was comprised of five underwriting units, each with product-focused specialists servicing brokers, agents and insureds across the United States from their respective underwriting unit locations. In early 2008, we decided to close the Markel Re unit. Markel Re’s excess and umbrella program, casualty facultative placements and public entity business remained within the Excess and Surplus Lines segment, while the alternative risk transfer programs were combined with the Markel Specialty unit in the Specialty Admitted segment. In March 2009, we transitioned the four underwriting units included in our Excess and Surplus Lines segment to a customer-focused regional office model as part of our “One Markel” initiative. Each regional office is responsible for serving the wholesale producers located in its region. The underwriters at our regional offices have access to and expertise in all of our product offerings and are located closer to our producers.

Our Specialty Admitted segment writes risks that, although unique and hard-to-place in the standard market, must remain with an admitted insurance company for marketing and regulatory reasons. Our underwriting units in this segment write specialty program insurance for well-defined niche markets, personal and commercial property and liability coverages and workers’ compensation insurance. Our Specialty Admitted segment is comprised of three underwriting units: the Markel Specialty and Markel American Specialty Personal and Commercial Lines units and, beginning in the fourth quarter of 2010, our FirstComp workers’ compensation insurance unit. Our Specialty Admitted segment included an additional underwriting unit, Markel Global Marine and Energy, until late 2008 when we decided to close that unit and place its programs into run-off.

96  |

On October 15, 2010, we completed our acquisition of 100% of the outstanding shares of Aspen Holdings, Inc. (Aspen), a Nebraska-based privately held corporation whose FirstComp insurance group provides workers’ compensation insurance and related services, principally to small businesses, in 31 states. This acquisition will provide us with the ability to expand our insurance operations to include workers’ compensation coverage.

Our London Insurance Market segment writes specialty property, casualty, professional liability, equine, marine, energy and trade credit insurance and reinsurance on a worldwide basis. We participate in the London market through Markel International, which includes Markel Capital Limited and Markel International Insurance Company Limited (MIICL), wholly-owned subsidiaries. Markel Capital Limited is the corporate capital provider for Markel Syndicate 3000 at Lloyd’s, which is managed by Markel Syndicate Management Limited, a wholly-owned subsidiary.

For purposes of segment reporting, the Other Insurance (Discontinued Lines) segment includes lines of business that have been discontinued in conjunction with an acquisition. This segment also includes development on asbestos and environmental loss reserves.

A favorable insurance market is commonly referred to as a “hard market” within the insurance industry and is characterized by stricter coverage terms, higher prices and lower underwriting capacity. Periods of intense competition, which typically include broader coverage terms, lower prices and excess underwriting capacity, are referred to as a “soft market.” After a decade of soft market conditions, the insurance industry experienced favorable conditions beginning in late 2000, which continued through 2003 for most product lines. During 2004, the market began to soften and the industry began to show signs of increased competition. Since 2005, we have been in a soft insurance market and have experienced intense competition. During the current soft market cycle, we have experienced price deterioration in virtually all of our product areas due in part to an increased presence of standard insurance companies in our markets. During 2008, given the rapid deterioration in underwriting capacity as a result of the disruptions in the financial markets and losses from catastrophes, the rate of decline in prices began to slow. However, the effects of the economic environment contributed to further declines in gross premium volume in 2009 and 2010. Premiums for many of our product lines are based upon our insureds’ revenues, gross receipts or payroll, which have been negatively impacted by the depressed levels of business activity in recent years. In 2010, we continued to experience pricing pressure due in part to intense competition, which resulted in further price deterioration across many of our product lines, most notably our professional and products liability programs within the Excess and Surplus Lines segment. However, we experienced moderate price increases in several product lines during 2010, most notably those offered by Markel International.

We routinely review the pricing of our major product lines and have pursued price increases in many product areas; however, as a result of continued soft insurance market conditions, our targeted price increases have been met with resistance in the marketplace, particularly within the Excess and Surplus Lines segment. In general, we believe prevailing rates within the property and casualty insurance marketplace are lower than our targeted pricing levels. 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 for many of our product lines, most notably within the Excess and Surplus Lines segment, has declined and, if the competitive environment does not improve, could decline further in the future.

Through our wholly-owned subsidiary Markel Ventures, Inc., we own interests in various businesses that operate outside of the specialty insurance marketplace. These businesses are viewed by management as separate and distinct from our insurance operations. Local management teams oversee the day-to-day operations of these companies, while strategic decisions are made in conjunction with members of our executive management team, principally our President and Chief Investment Officer. The financial results of those companies in which we own controlling interests have been consolidated in our financial statements. The financial results of those companies in which we hold a noncontrolling interest are accounted for under the equity method of accounting.

MANAGEMENT’S DISCUSSION & ANALYSIS

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

Our strategy in making these private equity investments is similar to our strategy for purchasing equity securities. We seek to invest in profitable companies, with honest and talented management, that exhibit reinvestment opportunities and capital discipline, at reasonable prices. We intend to own the businesses acquired for a long period of time.

Our non-insurance operations, which are referred to collectively as Markel Ventures, are comprised of a diverse portfolio of companies from various industries, including manufacturers of dredging equipment, high-speed bakery equipment and laminated furniture products and an owner and operator of manufactured housing communities. During the second quarter of 2010, we acquired a controlling interest in a manufacturer of food processing equipment, and we acquired a noncontrolling interest in a real estate investment fund manager. During the fourth quarter of 2010, we acquired controlling interests in a company that provides retail intelligence services and a company that manages behavioral health programs.

For further discussion of our lines of business, principal products offered, distribution channels, competition, underwriting philosophy and our non-insurance operations, see the discussion under Business Overview beginning on page 12.

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 and investing results. We measure underwriting results by our underwriting profit or loss and combined ratio. We measure investing results by our total investment return. These measures are discussed in greater detail under “Results of Operations.”

Net income to shareholders for 2010 increased 32% compared to 2009 as a result of improved investment returns, which was partially offset by an increase in income taxes and a deterioration in underwriting results due in part to higher losses from catastrophes and losses associated with the adverse conditions in the residential mortgage market. The results for 2009 improved $260.4 million compared to 2008 primarily due to lower net realized investment losses, as well as better underwriting performance as a result of a benign hurricane season and increased underwriting profits from our international operations, which were offset in part by a lower income tax benefit as compared to 2008. For both 2010 and 2009,

lower write downs for other-than-temporary declines in the estimated fair value of investments contributed to improved investment returns. Net income to shareholders for 2010 included $12.2 million of write downs for other-than-temporary declines in the estimated fair value of investments compared to $90.0 million and $339.2 million in 2009 and 2008, respectively. The components of net income (loss) to shareholders are discussed in further detail under “Underwriting Results,” “Investing Results,” “Non-Insurance Operations” and “Interest Expense and Income Taxes.”

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.

The following table presents selected data from our underwriting operations.

⁽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.

⁽²⁾ NM—Ratio is not meaningful. Further discussion of Other Insurance (Discontinued Lines) underwriting loss follows.

The 2010 combined ratio increased from 2009 due to a higher current accident year loss ratio and a higher expense ratio, partially offset by more favorable development of prior years’ loss reserves. The 2010 combined ratio included $33.0 million, or two points, of underwriting loss on the Chilean earthquake and the Deepwater Horizon drilling rig explosion. The 2009 combined ratio decreased from 2008 due to more favorable development of prior years’ loss reserves and a lower current accident year loss ratio, which were partially offset by a higher expense ratio. The lower current accident year loss ratio in 2009 was due to a benign hurricane season in 2009. The higher expense ratios in 2010 and 2009 were primarily due to declines in earned premiums and to costs associated with the implementation of our Atlas system and business process initiative.

MANAGEMENT’S DISCUSSION & ANALYSIS

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

The 2010 expense ratio included $46 million, or three points, of costs associated with the implementation of our Atlas system and business process initiative compared to $33 million, or two points, for 2009 and $20 million, or one point, for 2008. During the third quarter of 2010, in response to continuous assessments of cost, organizational effort, program complexity and enterprise risks associated with the Atlas initiative, we re-focused and simplified our implementation approach. While our ultimate objectives remain unchanged, we focused our attention on the successful delivery of the billing and collections system in October 2010 and the development and delivery of a data warehouse and agency internet functionality in 2011. We believe we can be more successful by completing these projects before proceeding with development of the remaining initiatives. Previously capitalized costs of $7.7 million were expensed during the third quarter of 2010.

The 2010 combined ratio included $74.7 million, or four points, of underwriting loss for two programs previously underwritten in the Excess and Surplus Lines segment that were exposed to losses associated with the adverse conditions in the residential mortgage market in recent years. The 2009 combined ratio included $35.5 million, or two points, of underwriting loss from these same two programs. The first of these programs provided coverage to financial institutions for losses on defaults by borrowers on second mortgages and home equity loans. We have been in the process of exiting this program since the first quarter of 2009. During the third quarter of 2010, we settled litigation related to this program with Guaranty Bank, the program’s largest insured, and recognized an underwriting loss of $19.9 million. The second of these programs was an errors and omissions program for mortgage servicing companies, which primarily experienced losses on the 2008 and 2007 accident years. We placed this program into run-off in the third quarter of 2010. Exposure on both programs is principally with regard to loan transactions that occurred before the end of 2008. Delinquencies and losses with regard to these loans have been greater than anticipated, resulting in greater frequency and severity of claims under both programs. Our loss reserves are based on judgments about the future performance of the underlying loans; however, continued weakness or other disruptions in the residential housing markets may result in additional loss experience and require strengthening of our loss reserves.

The 2010 combined ratio included $278.0 million of favorable development on prior years’ loss reserves compared to $235.3 million in 2009 and $163.8 million in 2008. The favorable development on prior years’ loss reserves during the past three years was primarily due to loss reserve redundancies at Markel International and on our professional and products liability programs within the Excess and Surplus Lines segment. Loss reserve redundancies at Markel International were $117.7 million, $108.1 million and $58.3 million in 2010, 2009 and 2008, respectively. Loss reserve redundancies on our professional and products liability programs within the Excess and Surplus Lines segment were $96.7 million, $97.5 million and $91.3 million in 2010, 2009 and 2008, respectively.

Over the past three years, we have experienced significant redundancies in prior years’ loss reserves. The product lines that have produced these redundancies are primarily long-tail books of business that take many years to fully develop. The positive trend in these prior years’ loss reserves was partially the result of the more favorable rates and terms associated with the hard insurance market that we experienced from 2000 through 2004. Although the favorable rates and terms obtained during the hard insurance market created expectations of improved underwriting results, the full impact from this favorable environment could not be quantified when we initially established loss reserves for these years. Additionally, the positive trend in these prior years’ loss reserves was due in part to the adverse impact of softening insurance market conditions and poor economic conditions experienced in recent years not being as significant as initially anticipated. Since 2005, we have been in a soft insurance market. In 2008 and 2009, we experienced a significant economic slowdown from the recessionary environment. Given the volatile nature of our long-tail books of business, the ultimate adverse impact of the soft insurance market and unfavorable economic environment could not be quantified when we initially established loss reserves for these years. In each

100  |

of the past three years, actual claims reporting patterns have been more favorable than we initially anticipated.

In connection with our quarterly reviews of loss reserves, the actuarial methods we used have exhibited a favorable trend for the 2003 to 2009 accident years. This trend was observed using statistical analysis of actual loss experience for those years, particularly with regard to our long-tail books of business within the Excess and Surplus Lines and London Insurance Market segments, which developed more favorably than we had expected based upon our historical experience. As actual losses experienced on these accident years have continued to be lower than anticipated, it has become more likely that the underwriting results will prove to be better than originally estimated. Additionally, as most actuarial methods rely upon historical reporting patterns, the favorable trends experienced on earlier accident years have resulted in a re-estimation of our ultimate incurred losses on more recent accident years. When we experience loss frequency or loss severity trends that are more favorable than we initially anticipated, we often evaluate the loss experience over a period of several years in order to assess the relative credibility of loss development trends. In each of the past three years, based upon our evaluations of claims development patterns in our long-tail, and often volatile, lines of business, we gave greater credibility to the favorable trend. As a result, our actuaries reduced their estimates of ultimate losses, and management incorporated this favorable trend into its best estimate and reduced prior years’ loss reserves accordingly.

While we believe it is possible that there will be additional redundancies on prior years’ loss reserves in 2011, we caution readers not to place undue reliance on this favorable trend. In 2004, we began to see a softening of the insurance market and experienced a slow down in the rate of increase in prices as a result of increased competition. Competition remained strong in 2005 and increased further from 2006 through 2010, resulting in deterioration in pricing over this period of time. Further, the ultimate impact that the financial crisis and related economic recession of 2008 and 2009 will have on our underwriting results is difficult to quantify. Redundancies on prior years’ loss reserves also will be impacted by the decline in earned premiums, which have decreased each of the past four years. Similar to the impact of the hardening of the insurance market that began in 2000, the impact on our underwriting results from the soft insurance market and adverse economic conditions cannot be fully quantified in advance.

The following discussion provides more detail by segment of the underwriting results described above. This segment-based discussion is supplemented by a summary of prior years’ loss reserve development on page 106.

Excess and Surplus Lines Segment

The Excess and Surplus Lines segment’s combined ratio for 2010 was 96% compared to 96% in 2009 and 92% (including three points of losses on Hurricanes Gustav and Ike) in 2008. In 2010, a higher current accident year loss ratio and a higher expense ratio were offset by more favorable development of prior years’ loss reserves compared to 2009. The 2010 combined ratio included $74.7 million, or ten points, of underwriting loss on two programs described earlier that were impacted by the adverse conditions in the residential mortgage market in recent years. The 2009 combined ratio included $35.5 million, or four points, of underwriting loss from these same two programs. The combined ratio increased in 2009 due to a higher expense ratio and a higher current accident year loss ratio on non-catastrophe-exposed lines of business, which were partially offset by more favorable development of prior years’ loss reserves compared to 2008. The higher expense ratios in 2010 and 2009 were primarily due to declines in earned premiums and to costs associated with the implementation of our Atlas initiative. The higher current accident year loss ratio in 2009 was due in part to higher than expected incurred losses during 2009 in certain professional liability programs, most notably our architects and engineers book of business, as a result of adverse economic conditions.

MANAGEMENT’S DISCUSSION & ANALYSIS

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

In 2010, the Excess and Surplus Lines segment’s results included $159.0 million of favorable development on prior years’ loss reserves compared to $130.8 million in 2009 and $118.8 million in 2008. The redundancies on prior years’ loss reserves experienced within the Excess and Surplus Lines segment during 2010, 2009 and 2008 were primarily on our professional and products liability programs due to lower loss severity than originally anticipated. As the average claim severity estimates on these long-tail books of business have decreased, our actuarial estimates of the ultimate liability for unpaid losses and loss adjustment expenses were reduced, and management reduced prior years’ loss reserves accordingly. In 2010, the increase in favorable development on prior year’s loss reserves compared to 2009 was primarily due to more favorable loss reserve development on certain long-tail casualty lines of business, most notably our brokerage general liability, excess and umbrella and environmental programs. In 2009, the increase in favorable development on prior year’s loss reserves compared to 2008 was primarily due to less adverse loss reserve development at the Markel Re unit.

The favorable development of prior years’ loss reserves during 2010 included $96.7 million of redundancies on our professional and products liability programs, of which $79.8 million was on the 2006 to 2009 accident years. The favorable development of prior years’ loss reserves during 2009 included $97.5 million of redundancies on our professional and products liability programs, of which $91.0 million was on the 2004 to 2008 accident years. The favorable development of prior years’ loss reserves during 2008 included $91.3 million of redundancies on our professional and products liability programs, of which $84.9 million was on the 2004 to 2007 accident years. The favorable development experienced in 2010, 2009 and 2008 on our long-tail professional and products liability books of business was primarily the result of lower loss severity than was originally anticipated. In each of the periods presented, the product lines that produced the majority of the redundancy were the specified medical, medical malpractice and products liability programs. In 2010, the average claim severity estimate on the 2006 to 2009 accident years for these product lines declined by 11% compared to 2009. In 2009, the average claim severity estimate on the 2004 to 2008 accident years for these product lines declined by 13% compared to 2008. As a result of these decreases in severity, our actuarial estimates of the ultimate liability for unpaid losses and loss adjustment expenses were reduced, and management reduced prior years’ loss reserves accordingly.

In 2010, we experienced $55.4 million of redundancies on our brokerage general liability, excess and umbrella and environmental programs on the 2003 to 2009 accident years. In 2003, as a result of previous adverse loss experience, we took significant corrective actions within our brokerage casualty operations, including the re-underwriting and re-pricing of the ongoing business. Our brokerage casualty business includes product lines that are long-tail and volatile in nature. During 2010, actual incurred losses and loss adjustment expenses on reported claims for the 2003 to 2009 accident years were $12.9 million less than we anticipated in our actuarial analyses. As a result, our actuaries reduced their estimates of ultimate losses, and management assigned greater credibility to this favorable experience and reduced prior years’ loss reserves accordingly.

The favorable development of prior years’ loss reserves during 2008 included $25.6 million of redundancies at the Markel Essex Excess and Surplus Lines unit, of which $21.6 million was on the 2005 to 2007 accident years. In 2008, the favorable development on prior years’ loss reserves at the Markel Essex Excess and Surplus Lines unit was primarily within the casualty programs and resulted from better than expected case loss activity.

The adverse loss experience at the Markel Re unit during 2008 primarily resulted from higher than expected average claim frequency and severity on two general liability programs that were cancelled in the first quarter of 2007. In 2008, the Markel Re unit experienced $30.9 million of adverse development on prior years’ loss reserves, of which $27.9 million related to these two programs. This adverse development was primarily on the 2005 to 2007 accident years.

102  |

Specialty Admitted Segment

The Specialty Admitted segment’s combined ratio for 2010 was 100% compared to 99% in 2009 and 106% (including five points of losses on Hurricanes Gustav and Ike) in 2008. The combined ratio increased in 2010 compared to 2009 due to a higher current accident year loss ratio and higher expense ratio, partially offset by more favorable development of prior years’ loss reserves. Aside from the impact of Hurricanes Gustav and Ike, the combined ratio decreased in 2009 due to a lower current accident year loss ratio and a lower expense ratio compared to 2008. Due to corrective actions taken during late 2008 and early 2009, we did not experience the same pattern of adverse loss development on the 2009 accident year for our specialty program business as we experienced in 2008. The decrease in the expense ratio for 2009 was primarily due to our decision in the fourth quarter of 2008 to close the Markel Global Marine and Energy unit.

The Specialty Admitted segment’s results included $4.7 million of favorable development on prior years’ loss reserves in 2010 compared to adverse development of $0.3 million and favorable development of $16.5 million in 2009 and 2008, respectively. The favorable development in 2010 was primarily due to redundancies of prior years’ loss reserves at the Markel American Specialty Personal and Commercial Lines unit. The redundancies at the Markel American Specialty Personal and Commercial Lines unit during 2010 were primarily on the 2007 to 2009 accident years. In 2009, favorable development on prior years’ loss reserves at the Markel American Specialty Personal and Commercial Lines unit, primarily on the 2008 accident year, was more than offset by adverse development on prior years’ loss reserves at the Markel Global Marine and Energy and Markel Specialty units. In 2008, $12.6 million of the favorable development on prior years’ loss reserves was on the 2006 and 2007 accident years. The favorable development in 2008 was primarily due to better than expected case loss activity at the Markel Specialty unit.

Beginning in the fourth quarter of 2010, the Specialty Admitted segment’s results included our FirstComp workers’ compensation operations. The workers’ compensation insurance market continues to be adversely impacted by high rates of unemployment, unfavorable economic conditions and a challenging pricing environment. As a result, we believe that it is likely that our FirstComp operations will produce an underwriting loss in 2011, which could approximate $30 million.

London Insurance Market Segment

The London Insurance Market segment’s combined ratio for 2010 was 95% compared to 91% in 2009 and 104% (including eight points of losses on Hurricanes Gustav and Ike) in 2008. The 2010 combined ratio included $33.0 million, or six points, of underwriting loss on the Chilean earthquake and the Deepwater Horizon drilling rig explosion. Excluding the effects of losses from these two catastrophes, the London Insurance Market segment’s combined ratio for 2010 decreased compared to 2009 primarily due to more favorable development on prior years’ loss reserves. Aside from the impact of Hurricanes Gustav and Ike, the combined ratio decreased in 2009 due to greater favorable development of prior years’ loss reserves as compared to 2008.

The London Insurance Market segment’s 2010 combined ratio included $117.7 million of favorable development on prior years’ loss reserves, of which $76.3 million was on the 2004 to 2007 accident years. This favorable development of prior years’ loss reserves occurred in a variety of programs across each of our divisions and was due in part to the adverse impact of softening insurance market conditions since 2005 and recent poor economic conditions not being as significant as initially anticipated. During 2010, actual incurred losses and loss adjustment expenses on reported claims for the 2004 to 2007 accident years were less than we originally expected. As a result of this favorable experience, our actuarial estimates of the ultimate liability for unpaid losses and loss adjustment expenses were reduced by $29.9 million, and management reduced prior years’ loss reserves accordingly.

MANAGEMENT’S DISCUSSION & ANALYSIS

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

The favorable development of prior years’ loss reserves experienced in 2010 included $33.7 million of redundancies on the 2001 and prior accident years. These redundancies predominantly related to marine and aviation liability and professional indemnity business written prior to our acquisition of Markel International in 2000. During 2010, we completed a comprehensive claims file review of all significant open claims for these older accident years. The claims file review highlighted better than expected case loss activity due in part to favorable claims settlements experienced in 2010. Based on the results of the claims file review, there was less uncertainty with regard to the ultimate settlement amount of the remaining open claims, and we reduced prior years’ loss reserves accordingly.

In 2010, the loss reserve redundancies in the London Insurance Market segment were partially offset by $35.0 million of adverse loss reserve development on prior years’ loss reserves in the Professional and Financial Risks division related to medical malpractice coverage for Italian hospitals. In 2005, we started writing medical malpractice coverage for Italian hospitals. This business was written until late 2008 when, as a result of higher than expected loss frequency and severity, we exited this class. During 2010, we completed a detailed review of all reported claims within the medical malpractice class, which highlighted that ultimate loss severity is expected to be greater than previously anticipated due in part to an increasingly adverse legal environment for medical malpractice insurers in Italy. As a result, our actuaries increased their estimates of ultimate losses, and management increased prior years’ loss reserves accordingly.

The London Insurance Market segment’s 2009 combined ratio included $108.1 million of favorable development on prior years’ loss reserves, of which $84.5 million related to the 2003 to 2007 accident years. This favorable development on prior years’ loss reserves occurred in a variety of programs across each of our divisions, most notably the professional liability programs in the Retail and the Professional and Financial Risks divisions. During 2009, actual incurred losses and loss adjustment expenses on reported claims for the 2003 to 2007 accident years were $39.9 million less than we expected in our actuarial analyses. As a result of this favorable experience, our actuarial estimates of the ultimate liability for unpaid losses and loss adjustment expenses were reduced, and management reduced prior years’ loss reserves accordingly.

The London Insurance Market segment’s 2008 combined ratio included $58.3 million of favorable development on prior years’ loss reserves of which $36.5 million was on the professional liability programs at the Professional and Financial Risks and the Retail divisions on the 2002 to 2005 accident years. This favorable development on prior years’ loss reserves was primarily due to the favorable rates and terms associated with the London market in those years. During 2008, actual incurred losses and loss adjustment expenses on reported claims for the 2002 to 2005 accident years at the Professional and Financial Risks and the Retail divisions were $26.4 million less than we expected in our actuarial analyses. As a result of this favorable experience, our actuarial estimates of the ultimate liability for unpaid losses and loss adjustment expenses were reduced, and management reduced prior years’ loss reserves accordingly.

In 2008, the London Insurance Market segment’s results included $28.9 million of adverse development on prior years’ loss reserves within the Professional and Financial Risks division on the 2006 and 2007 accident years related to our medical malpractice coverage for Italian hospitals. During 2008, losses on reported claims for this book of business were higher than expected. In addition to increased severity on reported claims, we experienced a higher than expected incidence of newly reported claims. As a result of the increase in loss frequency and severity experienced during 2008 for this class, our actuaries increased their estimates of ultimate losses, and management increased prior years’ loss reserves accordingly. This adverse experience on the 2006 and 2007 accident years was offset by favorable development on prior years’ loss reserves in other classes on the same accident years.

104  |

The underwriting performance for this segment may vary to a greater degree than our other segments due to Markel International’s current mix of business, which includes a high percentage of catastrophe-exposed business, higher average policy limits and lower use of reinsurance.

Results for the London Insurance Market segment for 2010 and 2009 also included the results of Elliott Special Risks (ESR), a Canadian managing general agent that we acquired in October 2009. ESR had operating revenues of $6.8 million and $4.1 million in 2010 and 2009, respectively. Operating revenues were primarily related to commission income from third party insurance entities. Operating revenues and expenses for ESR are included in other revenues and other expenses in the consolidated statement of operations and comprehensive income (loss).

Other Insurance (Discontinued Lines) Segment

The majority of the losses and loss adjustment expenses and the underwriting, acquisition and insurance expenses for the Other Insurance (Discontinued Lines) segment are associated with asbestos and environmental exposures or discontinued Markel International programs, most of which were discontinued upon acquisition, or shortly thereafter. Given the insignificant amount of premium earned in the Other Insurance (Discontinued Lines) segment, we evaluate this segment’s underwriting performance in terms of dollars of underwriting loss instead of its combined ratio.

The Other Insurance (Discontinued Lines) segment produced an underwriting loss of $3.1 million in 2010 compared to $4.7 million in 2009 and $28.1 million in 2008. Following the completion of our annual review of asbestos and environmental exposures, we increased loss reserves by $10.0 million and $24.9 million in 2009 and 2008, respectively. In 2009, the increase in loss reserves for asbestos and environmental exposures was partially offset by favorable development of loss reserves in other discontinued lines of business.

During the third quarter of each of the past three years, we completed an in-depth, actuarial review of our asbestos and environmental exposures. During our 2010 review, we determined that no adjustment to loss reserves was necessary. During our 2009 review, we increased our estimate of the number of claims that would ultimately be closed with an indemnity payment. During our 2008 review, we noted that claims had been closed with total indemnity payments that were higher than had been anticipated, and as a result of this higher than expected average severity on closed claims, our actuaries updated their average severity assumptions for both open claims and claims incurred but not yet reported. In 2009 and 2008, our actuarial estimates of the ultimate liability for asbestos and environmental loss reserves were increased, and management increased prior years’ loss reserves for asbestos and environmental exposures accordingly.

Asbestos and environmental loss reserves are subject to significant uncertainty due to potential loss severity and frequency resulting from an uncertain and unfavorable legal climate. Our asbestos and environmental reserves are not discounted to present value and are forecasted to pay out over the next 50 years. We seek to establish appropriate reserve levels for asbestos and environmental exposures; however, these reserves could be subject to increases in the future. See note 8 of the notes to consolidated financial statements for further discussion of our exposures to asbestos and environmental claims.

Over the past three years, we have experienced favorable development on prior years’ loss reserves ranging from 4% to 6% of beginning of year net loss reserves. In 2010, we experienced favorable development of $278.0 million, or 6% of beginning of year net loss reserves, compared to $235.3 million, or 5% of beginning of year net loss reserves, in 2009 and $163.8 million, or 4% of beginning of year net loss reserves, in 2008.

It is difficult for management to predict the duration and magnitude of an existing trend and, on a relative basis, it is even more difficult to predict the emergence of factors or trends that are unknown today but may have a material impact on loss reserve development. In assessing the likelihood of whether the above favorable trends will continue and whether other trends may develop, we believe that a reasonably likely movement in prior years’ loss reserves during 2011 would range from a deficiency of approximately 1%, or $50 million, to a redundancy of approximately 6%, or $275 million, of December 31, 2010 net loss reserves.

Premiums

The following table summarizes gross premium volume by segment.

GROSS PREMIUM VOLUME	Years Ended December 31,
(dollars in thousands)	2010		2009		2008
Excess and Surplus Lines	$	898,409	$	962,702	$	1,163,992
Specialty Admitted		375,036		301,827		355,061
London Insurance Market		708,968		641,226		693,138
Other Insurance (Discontinued Lines)		54		138		593
TOTAL	$	1,982,467	$	1,905,893	$	2,212,784

Excess and Surplus Lines segment gross premium volume decreased 7% in 2010 compared to 2009 and decreased 17% in 2009 compared to 2008. The decrease in both periods was primarily the result of continued intense competition across many of our product lines and the effects of the economic environment. Premiums for many of our product lines are based upon our insureds’ revenues, gross receipts or payroll, which have been negatively impacted by the depressed levels of business activity that began in 2008. In 2010, the Excess and Surplus Lines segment included $18.8 million of gross premium volume related to our settlement with Guaranty Bank.

In 2010, gross premium volume in both the Excess and Surplus Lines and Specialty Admitted segments was impacted by the transfer of certain programs from the Excess and Surplus Lines segment to the Specialty Admitted segment. This transfer had no impact on total gross premium volume and was made to better align the reporting of these programs with their distribution strategy. In 2010, the Specialty Admitted segment included approximately $25 million of gross premium volume on these transferred programs.

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

Specialty Admitted segment gross premium volume increased 24% in 2010 compared to 2009. In 2010, the Specialty Admitted segment included $40.7 million of gross premium volume from FirstComp. The increase in 2010 also was due to the transfer of certain programs from the Excess and Surplus Lines segment. Specialty Admitted segment gross premium volume decreased 15% in 2009 compared to 2008. In late 2008, we decided to close the Markel Global Marine and Energy unit and place its programs into run-off, which accounted for $28.1 million of the decline in gross premium volume in 2009. The decline in gross premium volume in 2009 was also partially the result of competition across many of our product lines and the effects of the economic environment.

London Insurance Market segment gross premium volume increased 11% in 2010 compared to 2009. This increase was due in part to our acquisition of ESR in October 2009. Foreign currency exchange rate movements did not have a significant impact on gross premium volume in 2010. London Insurance Market segment gross premium volume decreased 7% in 2009 compared to 2008. Had currency exchange rates remained constant in 2009, gross written premiums would have decreased less than 1% compared to 2008.

The following table summarizes net written premiums by segment.

NET WRITTEN PREMIUMS	Years Ended December 31,
(dollars in thousands)	2010		2009			2008
Excess and Surplus Lines	$	797,518	$	869,695		$	1,028,816

Other Insurance (Discontinued Lines)		167		(598	)		625
TOTAL	$	1,769,118	$	1,714,409		$	1,968,496

Net retention of gross premium volume was 89% in 2010 compared to 90% in 2009 and 89% in 2008. In 2010, net written premiums in the London Insurance Market segment were reduced by $11.0 million of additional reinsurance costs resulting from the Deepwater Horizon loss. As part of our underwriting philosophy, we seek to offer products with limits that do not require significant amounts of reinsurance. We purchase reinsurance in order to reduce our retention on individual risks and enable us to write policies with sufficient limits to meet policyholder needs.

The following table summarizes earned premiums by segment.

EARNED PREMIUMS	Years Ended December 31,
(dollars in thousands)	2010		2009			2008
Excess and Surplus Lines	$	809,672	$	940,098		$	1,089,967

Other Insurance (Discontinued Lines)		168		(598	)		625
TOTAL	$	1,730,921	$	1,815,835		$	2,022,184

Excess and Surplus Lines earned premiums decreased 14% in 2010 compared to 2009 and decreased 14% in 2009 compared to 2008. The decrease in both periods was a result of lower gross premium volume across most of the product lines included in this segment. In 2010, the Excess and Surplus Lines segment included $18.8 million of earned premiums related to our settlement with Guaranty Bank.

108  |

Specialty Admitted earned premiums increased 13% in 2010 compared to 2009. In 2010, the Specialty Admitted segment included $36.9 million of earned premiums from FirstComp. The increase in 2010 also was due to the transfer of certain programs from the Excess and Surplus Lines segment. Specialty Admitted earned premiums decreased 4% in 2009 compared to 2008. This decrease was primarily due to lower earned premiums at the Markel Global Marine and Energy unit as a result of our decision in late 2008 to close this unit and place its programs into run-off.

London Insurance Market earned premiums increased 1% in 2010 compared to 2009. This increase was primarily a result of higher gross premium volume. In 2010, earned premiums in the London Insurance Market segment were reduced by $11.0 million of additional reinsurance costs resulting from the Deepwater Horizon loss. Foreign currency exchange rate movements did not have a significant impact on earned premiums in 2010. London Insurance Market earned premiums decreased 7% in 2009 compared to 2008 due to the effects of foreign currency exchange rate movements. Had currency exchange rates remained constant in 2009, earned premiums would have decreased 1% compared to 2008.

Investing Results

Our business strategy recognizes the importance of both consistent underwriting and operating profits and superior investment returns to build shareholder value. We rely on sound underwriting practices to produce investable funds while minimizing underwriting risk. We believe it is important to evaluate investment performance by measuring total investment return. Total investment return includes items that impact net income (loss), such as net investment income and realized investment gains or losses, as well as changes in unrealized gains or losses, which do not impact net income (loss). We focus on long-term total investment return, understanding that the level of realized and unrealized investment gains or losses may vary from one period to the next. Taxable equivalent total investment return provides a measure of investment performance that considers the yield of both taxable and tax-exempt investments on an equivalent basis.

Our investment results over the past three years were impacted by the considerable dislocation of global financial markets that began in 2008 and included the worst declines in the U.S. equity markets since the Great Depression, which were followed by significant recoveries beginning in the latter half of 2009. During 2009 and 2008, we increased our holdings of short-term investments and cash and cash equivalents and also shifted the allocation of our fixed maturity portfolio from corporate bonds to government and municipal bonds. In addition, as bonds matured, we reinvested a portion of the proceeds in short-term investments. During 2010, given the improvement in the financial markets over the latter half of 2009 and continuing into 2010, we increased our purchases of fixed maturities and equity securities and have been gradually shifting our investment portfolio’s allocation from short-term investments and cash and cash equivalents to higher yielding investment securities. At December 31, 2010, equity securities represented 21% of our invested assets compared to 17% at December 31, 2009. At December 31, 2010, short-term investments and cash and cash equivalents represented 13% of our invested assets compared to 17% at December 31, 2009.

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

The following table summarizes our investment performance.

	Years Ended December 31,
(dollars in thousands)	2010			2009			2008
Net investment income	$	272,530		$	259,809		$	282,148

Invested assets, end of year	$	8,223,796		$	7,848,673		$	6,892,806

⁽¹⁾ Investment yield reflects net investment income as a percentage of average invested assets.

⁽²⁾ Taxable equivalent total investment return includes net investment income, realized investment gains or losses, the change in fair value of the investment portfolio and the effect of foreign currency exchange rate movements during the period as a percentage of average invested assets. Tax-exempt interest and dividend payments are grossed up using the U.S. corporate tax rate to reflect an equivalent taxable yield.

Investments and cash and cash equivalents (invested assets) increased 5% in 2010. The increase in the investment portfolio in 2010 was primarily due to an increase in net unrealized gains on investments of $243.7 million and cash flows from operations of $223.3 million. Invested assets increased 14% in 2009. The increase in the investment portfolio in 2009 was primarily due to an increase in net unrealized gains on investments of $566.7 million and cash flows from operations of $282.5 million.

Net investment income increased 5% in 2010, which was primarily due to having higher average invested assets and dividend income compared to 2009. Net investment income decreased 8% in 2009, which was primarily due to having lower yields and average invested assets. Our investment yields declined in 2009 as we increased our allocation to short-term investments and cash and cash equivalents and short-term interest rates declined. Also, dividend income in 2009 was lower than dividend income in 2008.

Net investment income in 2010 and 2009 included favorable changes in the fair value of our credit default swap of $1.7 million and $3.0 million, respectively. Net investment income in 2008 included an adverse change in the fair value of our credit default swap of $13.7 million. The fair value of the credit default swap was $25.2 million and $27.0 million at December 31, 2010 and December 31, 2009, respectively.

Net realized investment gains were $36.4 million in 2010 compared to net realized investment losses of $96.1 million in 2009 and net realized investment losses of $407.6 million in 2008. Net realized investment gains (losses) include both gains (losses) from sales of securities and losses from write downs for other-than-temporary declines in the estimated fair value of investments. In 2010, net realized investment gains included $12.2 million of write downs for other-than-temporary declines in the estimated fair value of investments compared to $90.0 million and $339.2 million in 2009 and 2008, respectively. In 2010, net realized investment gains were primarily related to equity securities and fixed maturities that were sold because of tax planning strategies or our decision to reallocate capital to other equity securities and fixed maturities with greater potential for long-term investment returns.

110  |

In 2010, net realized investment gains included $1.5 million of realized losses from sales of fixed maturities and equity securities. Net realized investment losses in 2009 and 2008 included $25.3 million and $142.8 million, respectively, of realized losses from sales of fixed maturities and equity securities. Proceeds received on securities sold at a loss were $36.0 million in 2010, $124.2 million in 2009 and $329.1 million in 2008.

Approximately 84% of the gross realized losses in 2010 related to securities that had been in a continuous unrealized loss position for less than one year. Gross realized losses in 2010 included $12.2 million of write downs for other-than-temporary declines in the estimated fair value of investments. These write downs were made with respect to eight equity securities, four fixed maturities and four real estate investments.

Approximately 69% of the gross realized losses in 2009 related to securities that had been in a continuous unrealized loss position for less than one year. Gross realized losses in 2009 included $90.0 million of write downs for other-than-temporary declines in the estimated fair value of investments. These write downs were made with respect to 29 equity securities, 15 fixed maturities and two investments in affiliates.

Write downs for other-than-temporary declines in the estimated fair value of investments for 2009 included write downs related to our equity holdings in General Electric Company and United Parcel Service, Inc. of $21.0 million and $9.5 million, respectively. Given the extent to which the fair value of these equity securities was below cost and management’s belief that these securities were unlikely to recover in the near term, the decline in fair value for these securities was deemed other-than-temporary and was recognized in net income. Write downs for other-than-temporary declines in the estimated fair value of investments for 2009 also included a $20.5 million write down related to our investment in First Market Bank due to an anticipated merger with Union Bankshares Corporation that was expected to reduce the value of our investment. In the first quarter of 2010, this merger was completed and did not result in a material adjustment to net income.

Approximately 70% of the gross realized losses in 2008 related to securities that had been in a continuous unrealized loss position for less than one year. Gross realized losses in 2008 included a $29.2 million loss on the sale of our equity holdings in LandAmerica Financial Group, Inc. and losses on the sales of our investments in fixed maturities issued by Lehman Brothers and Washington Mutual of $40.9 million and $32.1 million, respectively. All three of these companies filed for bankruptcy during 2008. These losses were partially offset by a $34.6 million gain in 2008 on the sale of our holdings in Anheuser-Busch Companies, Inc., which we sold as a result of this company being acquired.

Gross realized losses in 2008 also included $339.2 million of write downs for other-than-temporary declines in the estimated fair value of investments. These write downs were made with respect to 52 equity securities, two nonredeemable preferred stocks and 15 fixed maturities. Approximately 23% of the write downs in 2008 were due to the determination that we no longer had the intent to hold these securities until they fully recovered in value as we began selling a portion of the securities in order to allocate capital to other securities with greater potential for long-term investment returns. The remainder of the write downs related to securities that had other indications of other-than-temporary impairment.

The most significant write downs of equity securities during 2008 related to our investments in General Electric Company, Citigroup Inc., Bank of America Corporation and International Game Technology, for which we had write downs of $64.9 million, $37.6 million, $23.4 million and $21.7 million, respectively. The General Electric Company, Bank of America Corporation and International Game Technology securities had significant declines in fair value that we believed

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

were unlikely to recover in the near term. As a result, the decline in fair value for these securities was deemed other-than-temporary and was charged to earnings. During 2008, we sold a portion of our holdings in Citigroup Inc. and, as a result, we determined that we no longer had the intent to hold this investment until it fully recovered its value. The two nonredeemable preferred stock write downs related to our holdings in Fannie Mae and Freddie Mac and totaled $9.0 million. The most significant write downs of fixed maturities related to our investments in Morgan Stanley and Kaupthing Bank, an Icelandic financial institution, for which we had write downs of $18.4 million and $12.1 million, respectively. During 2008, we sold a portion of our holdings in Morgan Stanley and, as a result, we determined that we no longer had the intent to hold this investment until it fully recovered its value. The write down on Kaupthing Bank was made because we believed we would not receive all interest and principal payments when due. The eight investments discussed above represent 55% of the total write down for other-than-temporary declines in the estimated fair value of investments during 2008.

In 2010 and 2009, net unrealized gains on investments increased $243.7 million and $566.7 million, respectively, due to increases in the estimated fair value of both our fixed maturity and equity portfolios as a result of improved financial market conditions during the latter half of 2009 and 2010. In 2008, net unrealized gains on investments decreased $507.5 million due to a decline in the estimated fair value of both our fixed maturity and equity portfolios as a result of disruptions in the financial markets.

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 December 31, 2010, we held securities with gross unrealized losses of $56.2 million, or less than 1% of our total invested assets. All securities with unrealized losses were reviewed, and we believe that there were no other securities with indications of declines in estimated fair value that were other-than-temporary at December 31, 2010. 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. See note 2(b) of the notes to consolidated financial statements for further discussion of unrealized losses.

Non-Insurance Operations (Markel Ventures)

Our non-insurance operations, which are referred to collectively as Markel Ventures, include the results of AMF Bakery Systems, ParkLand Ventures, Inc., Panel Specialists, Inc., Ellicott Dredge Enterprises, LLC, Solbern, Inc. and Markel Eagle Partners, LLC. In May 2010, we acquired a controlling interest in Solbern, Inc., a company based in Fairfield, New Jersey that manufactures food processing equipment, and we acquired a noncontrolling interest in Markel Eagle Partners, LLC, a real estate investment fund manager based in Glen Allen, Virginia. In December 2010, we acquired controlling interests in RD Holdings, LLC (RetailData), a company that provides retail intelligence services, and Diamond Healthcare Corporation, a company that manages behavioral health programs throughout the United States. RetailData and Diamond Healthcare Corporation are headquartered in Richmond, Virginia. Since we consolidate our non-insurance operations on a one-month lag, the results for these two acquisitions will be reported on a one-month lag and included in our consolidated results beginning in the first quarter of 2011.

112  |

Operating revenues and expenses associated with our non-insurance operations are included in other revenues and other expenses in the consolidated statements of operations and comprehensive income (loss). Revenues for our non-insurance operations were $166.5 million, $85.7 million and $79.8 million in 2010, 2009 and 2008, respectively. Revenues for our non-insurance operations increased in 2010 compared to 2009 primarily due to our acquisitions of Ellicott Dredge Enterprises, LLC and Panel Specialists, Inc. in late 2009. We anticipate that revenues for our non-insurance operations will exceed $250 million in 2011.

Interest Expense and Income Taxes

Interest expense was $73.7 million in 2010 compared to $54.0 million in 2009 and $48.2 million in 2008. The increases in interest expense in 2010 compared to 2009 and in 2009 compared to 2008 were primarily due to our issuance of $350 million of 7.125% unsecured senior notes in September 2009.

The effective tax rate was 9% in 2010, which included tax benefits associated with our foreign operations. Before considering the tax benefits related to foreign operations, the effective tax rate in 2010 was 22%, which differs from the statutory tax rate of 35% primarily as a result of tax-exempt investment income. The effective tax rate in 2010 included an 11% income tax benefit related to foreign operations as a result of a change in our plans regarding the amount of earnings considered permanently reinvested in foreign subsidiaries. The income tax benefit in 2009 was 2% of income before income taxes, which included tax benefits associated with our foreign operations. Before considering the tax benefits related to foreign operations, the effective tax rate in 2009 was 19%, which differs from the statutory tax rate of 35% primarily as a result of tax-exempt investment income. The effective tax rate in 2009 included a 17% income tax benefit that resulted from a one-time tax benefit related to a change in United Kingdom tax law that became effective in the third quarter of 2009. The income tax benefit in 2008 was 63% of loss before income taxes. The rate of tax benefit was higher than that obtained by applying the statutory rate of 35% to loss before income taxes due to the additional tax benefits associated with favorable permanent differences, principally tax-exempt investment income and tax credits recognized during 2008. As a result of the tax attributes related to our foreign operations, our effective tax rate may vary in the future.

With few exceptions, we are no longer subject to income tax examination by tax authorities for years ended before January 1, 2007. See note 7 of the notes to consolidated financial statements for a discussion of factors affecting the realization of our gross deferred tax assets and unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in our income tax returns.

Comprehensive Income (Loss) To Shareholders

Comprehensive income to shareholders was $430.6 million in 2010 compared to comprehensive income to shareholders of $591.0 million in 2009 and comprehensive loss to shareholders of $403.3 million in 2008. Comprehensive income to shareholders for 2010 included an increase in net unrealized gains on investments, net of taxes, of $163.5 million and net income to shareholders of $266.8 million. Comprehensive income to shareholders for 2009 included an increase in net unrealized gains on investments, net of taxes, of $374.4 million and net income to shareholders of $201.6 million. Comprehensive loss to shareholders for 2008 included a decrease in net unrealized gains on investments, net of taxes, of $329.9 million and net loss to shareholders of $58.8 million.

Claims And Reserves

We maintain reserves for specific claims incurred and reported, reserves for claims incurred but not reported and reserves for uncollectible reinsurance. Our ultimate liability may be greater or less than current reserves. In the insurance industry, there is always the risk that reserves may prove inadequate. We continually monitor reserves using new information on reported claims and a variety of statistical techniques. Anticipated inflation is reflected implicitly in the reserving process through analysis of cost trends and the review of historical development. We do not discount our reserves for losses and loss adjustment expenses to reflect estimated present value.

The first line of the following table shows our net reserves for losses and loss adjustment expenses adjusted for commutations, foreign currency movements and other items. This adjustment is accomplished by revising the reserves for losses and loss adjustment expenses as originally estimated at the end of each year and all prior years for reserves either reassumed from reinsurers or ceded back to cedents through reinsurance commutation agreements. Adjustments also are made for the effects of changes in foreign currency rates since the reserves for losses and loss adjustment expenses were originally estimated. Net reserves for losses and loss adjustment expenses of acquired insurance companies are included in the year of acquisition.

The upper portion of the table shows the cumulative amount paid with respect to the previously recorded reserves as of the end of each succeeding year. The lower portion of the table shows the re-estimated amount of the previously recorded reserves based on experience as of the end of each succeeding year, including cumulative payments made since the end of the respective year. For example, the liability for losses and loss adjustment expenses at the end of 2005 for 2005 and all prior years, adjusted for commutations, foreign currency movements and other items, was originally estimated to be $4,182.2 million. Five years later, as of December 31, 2010, this amount was re-estimated to be $3,574.1 million, of which $2,243.3 million had been paid, leaving a reserve of $1,330.8 million for losses and loss adjustment expenses for 2005 and prior years remaining unpaid as of December 31, 2010.

MANAGEMENT’S DISCUSSION & ANALYSIS

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

Net cumulative redundancy (deficiency) represents the change in the estimate from the original balance sheet date to the date of the current estimate. For example, the liability for losses and loss adjustment expenses developed a $608.1 million redundancy from December 31, 2005 to December 31, 2010. Conditions and trends that have affected the development of loss reserves in the past may not necessarily occur in the future. Accordingly, it may not be appropriate to extrapolate future redundancies or deficiencies based on the table. Gross cumulative redundancy (deficiency) is presented before deductions for reinsurance. Gross deficiencies and redundancies may be significantly more or less than net deficiencies and redundancies due to the nature and extent of applicable reinsurance. The net and gross cumulative redundancies as of December 31, 2010 for 2009 and prior years were primarily due to redundancies that developed during 2010 at Markel International and on our professional and products liability programs within the Excess and Surplus Lines segment on the 2003 to 2009 accident years. See “Underwriting Results” for further discussion of changes in prior years’ loss reserves.

See note 8 of the notes to consolidated financial statements and the discussion under “Critical Accounting Estimates” for a discussion of estimates and assumptions related to the reserves for losses and loss adjustment expenses.

Liquidity And Capital Resources

We seek to maintain prudent levels of liquidity and financial leverage for the protection of our policyholders, creditors and shareholders. Our target capital structure includes approximately 30% debt. Our debt to total capital ratio was 24% at December 31, 2010 and 26% at December 31, 2009. From time to time, our debt to total capital ratio may increase due to business opportunities that may be financed in the short term with debt. Alternatively, our debt to total capital ratio may fall below our target capital structure, which provides us with additional borrowing capacity to respond quickly when future opportunities arise.

At December 31, 2010, our holding company (Markel Corporation) held $885.6 million of invested assets, which approximated 12 times annual interest expense, compared to $1,020.9 million of invested assets at December 31, 2009. In order to maintain prudent levels of liquidity, we seek to maintain invested assets at Markel Corporation of at least two times annual interest expense. The excess liquidity at Markel Corporation is available to increase capital at our insurance subsidiaries, complete acquisitions, repurchase shares of our common stock or retire debt.

In October 2010, we completed our acquisition of Aspen. Total consideration for this acquisition was $135.6 million. As part of the consideration, outstanding options to purchase shares of Aspen’s common stock were converted into options to purchase 58,116 shares of our common stock at an average exercise price of $225.94 per share. These options had a fair value at acquisition of $6.7 million, net of taxes. Aspen shareholders also received contingent value rights that may result in the payment of additional cash consideration depending, among other things, upon the development of FirstComp’s loss reserves and loss sensitive profit commissions over time. Based on current expectations, we believe that it is unlikely that any contingent consideration will be paid related to the contingent value rights.

In November 2010, our Board of Directors approved the repurchase of up to $200 million of common stock under a share repurchase program (the Program). Under the Program, we may repurchase outstanding shares of common stock from time to time, primarily through open-market transactions. The Program has no expiration date but may be terminated by the Board of Directors at any time.

116  |

This repurchase program replaced a previous repurchase program that had been approved by the Board of Directors in August 2005. As of December 31, 2010, we had repurchased 7,956 shares of our common stock at a cost of $2.8 million under the Program.

Our insurance operations collect premiums and pay claims, reinsurance costs and operating expenses. Premiums collected and positive cash flows from the insurance operations are invested primarily in short-term investments and long-term fixed maturities. Short-term investments held by our insurance subsidiaries provide liquidity for projected claims, reinsurance costs and operating expenses. As a holding company, Markel Corporation receives cash from its subsidiaries as reimbursement for operating and other administrative expenses it incurs. The reimbursements are made within the guidelines of various management agreements between the holding company and its subsidiaries.

The holding company has historically relied upon dividends from its subsidiaries to meet debt service obligations. Under the insurance laws of the various states in which our domestic insurance subsidiaries are incorporated, an insurer is restricted in the amount of dividends it may pay without prior approval of regulatory authorities. At December 31, 2010, our domestic insurance subsidiaries could pay dividends of $197.0 million during the following twelve months under these laws. There are also regulatory restrictions on the amount of dividends that our foreign insurance subsidiaries may pay. We must provide 14 days advance notice to the Financial Services Authority before receiving dividends from MIICL. In addition, our foreign insurance subsidiaries must comply with the United Kingdom Companies Act of 2006, which provides that dividends may only be paid out of profits available for that purpose.

Net cash provided by operating activities decreased to $223.3 million in 2010 from $282.5 million in 2009 and $397.0 million in 2008. The decrease in 2010 compared to 2009 was due to lower cash flows from underwriting activities in the Excess and Surplus Lines segment and the receipt, in 2009, of $33.6 million related to our 2008 federal income tax refund. The decrease in 2009 compared to 2008 was due to lower cash flows from underwriting activities in the Excess and Surplus Lines segment, which was partially offset by the receipt of our 2008 federal income tax refund and lower income tax payments in 2009 compared to 2008.

Net cash used by investing activities was $283.3 million, $333.7 million and $152.0 million in 2010, 2009 and 2008, respectively. During 2010, given the improvement in the financial markets over the latter half of 2009 and continuing into 2010, we increased our purchases of fixed maturities and equity securities and have been gradually shifting our investment portfolio’s allocation from short-term investments and cash and cash equivalents to higher yielding investment securities. Net cash used by investing activities included $214.2 million, $154.9 million and $10.1 million of cash, net of cash acquired, used to complete acquisitions in 2010, 2009 and 2008, respectively. See note 21 of the notes to consolidated financial statements for a discussion of acquisitions.

Invested assets increased to $8.2 billion at December 31, 2010 from $7.8 billion at December 31, 2009. Net unrealized gains on investments, net of taxes, were $581.3 million at December 31, 2010 compared to $417.8 million at December 31, 2009. The increase in net unrealized gains on investments, net of taxes, in 2010 was primarily due to an increase in the estimated fair value of both our fixed maturity and equity portfolios as a result of continued recovery following the disruptions in the financial markets during 2008 and the first half of 2009. Equity securities were $1.7 billion, or 21% of invested assets, at December 31, 2010 compared to $1.3 billion, or 17% of invested assets, at December 31, 2009. See note 2(i) of the notes to consolidated financial statements for a discussion of restricted assets.

MANAGEMENT’S DISCUSSION & ANALYSIS

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

Net cash used by financing activities was $45.6 million in 2010 compared to net cash provided by financing activities of $251.6 million in 2009 and net cash used by financing activities of $58.3 million in 2008. During 2010, cash of $45.2 million was used to repurchase shares of our common stock. During 2009, we received net proceeds of $347.2 million associated with the issuance of $350 million of 7.125% unsecured senior notes due September 30, 2019, and we repaid $150 million of borrowings that were outstanding under our $375 million revolving credit facility. During 2008, we borrowed $100 million under our revolving credit facility, repaid $93.1 million on our 7.00% unsecured senior notes, which matured May 15, 2008, and used cash of $60.6 million to repurchase shares of our common stock.

Reinsurance recoverable on paid and unpaid losses was $0.9 billion at December 31, 2010 compared to $1.0 billion at December 31, 2009. The decrease in 2010 was due in part to a reduction in the reinsurance recoverable on unpaid losses related to favorable development on prior years’ loss reserves. Reinsurance recoverable on paid and unpaid losses at December 31, 2010 included $41.3 million of estimated reinsurance recoverables related to the Deepwater Horizon drilling rig explosion in April 2010.

In recent years, we have completed numerous reinsurance commutations, which involve the termination of ceded or assumed reinsurance contracts. Our commutation strategy related to ceded reinsurance contracts is to reduce credit exposure and eliminate administrative expenses associated with the run-off of reinsurance placed with certain reinsurers. Our commutation strategy related to assumed reinsurance contracts is to reduce our loss exposure to long-tailed liabilities assumed under reinsurance agreements entered into prior to our acquisition of Markel International. We will continue to pursue commutations when we believe they meet our objectives.

We have credit risk to the extent any of our reinsurers are unwilling or unable to meet their obligations under our reinsurance agreements. We attempt to minimize credit exposure to reinsurers through adherence to internal reinsurance guidelines. We monitor changes in the financial conditions of our reinsurers, and we assess our concentration of credit risk on a regular basis. At December 31, 2010, our reinsurance recoverable balance for the ten largest reinsurers was $692.5 million, representing 68% of our consolidated balance, before considering allowances for bad debts. Of the amounts due from the ten largest reinsurers, 95% was due from reinsurers rated “A” or better by A.M. Best. We are the beneficiary of letters of credit, trust accounts and funds withheld in the aggregate amount of $247.3 million at December 31, 2010, collateralizing reinsurance recoverable balances due from our ten largest reinsurers. See note 13 of the notes to consolidated financial statements for further discussion of reinsurance recoverables and exposures. While we believe that reinsurance recoverable balances are collectible, deterioration in reinsurers’ ability to pay or collection disputes could adversely affect our operating cash flows, financial position and results of operation.

Unpaid losses and loss adjustment expenses at December 31, 2010 decreased 1% compared to 2009 due in part to experiencing $278.0 million of favorable development on prior years’ loss reserves. The increase in the Specialty Admitted segment’s loss reserves in 2010 was primarily due to the acquisition of Aspen. See note 8 of the notes to consolidated financial statements and “Critical Accounting Estimates” for a discussion of estimates and assumptions related to unpaid losses and loss adjustment expenses.

The following table summarizes our contractual cash payment obligations at December 31, 2010.

⁽¹⁾ See notes 8, 9 and 14 of the notes to consolidated financial statements for further discussion of these obligations.

Senior long-term debt and other debt, excluding unamortized discount, was $1.0 billion and $974.1 million at December 31, 2010 and 2009, respectively. On June 9, 2010, we entered into a new revolving credit facility, which provides $270 million of capacity for working capital and other general corporate purposes. This facility replaced our previous $375 million revolving credit facility and expires in June 2013. We had no borrowings outstanding related to revolving credit facilities during 2010.

We were in compliance with all covenants contained in our revolving credit facility at December 31, 2010. To the extent that we are not in compliance with our covenants, our access to the credit facility could be restricted. While we believe this to be unlikely, the inability to access the credit facility could adversely affect our liquidity. See note 9 of the notes to consolidated financial statements for further discussion of our revolving credit facility.

Reserves for unpaid losses and loss adjustment expenses represent future contractual obligations associated with insurance and reinsurance contracts issued to our policyholders. Information presented in the table of contractual cash payment obligations is an estimate of our future payment of claims as of

MANAGEMENT’S DISCUSSION & ANALYSIS

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

December 31, 2010. Payment patterns for losses and loss adjustment expenses were generally based upon paid development factors over the past 10 years for each of our insurance subsidiaries. Each claim is settled individually based upon its merits and certain claims may take years to settle, especially if legal action is involved. The actual cash payments for settled claims will vary, possibly significantly, from the estimates shown in the preceding table.

At December 31, 2010, we had unrecognized tax benefits of $24.6 million related to uncertain tax positions. Due to the high degree of uncertainty regarding the timing of potential future cash flows associated with our unrecognized tax benefits, we are unable to make a reasonably reliable estimate of the amount and period in which any liabilities might be paid. See note 7 of the notes to consolidated financial statements for further discussion of our expectations regarding changes in unrecognized tax benefits during 2011.

At December 31, 2010, we had $1.6 billion of invested assets held in trust or on deposit for the benefit of policyholders, reinsurers or banks in the event of a default on our obligations. These invested assets and the related liabilities are included on our consolidated balance sheet. See note 2(i) of the notes to consolidated financial statements for further discussion of restrictions over our invested assets.

Our insurance operations require capital to support premium writings, and we remain committed to maintaining adequate capital and surplus at each of our insurance subsidiaries. The National Association of Insurance Commissioners (NAIC) developed a model law and risk-based capital formula designed to help regulators identify domestic property and casualty insurers that may be inadequately capitalized. Under the NAIC’s requirements, a domestic insurer must maintain total capital and surplus above a calculated threshold or face varying levels of regulatory action. At December 31, 2010, the capital and surplus of each of our domestic insurance subsidiaries was above the minimum regulatory thresholds.

Capital adequacy of our international insurance subsidiaries is regulated by the Financial Services Authority. At December 31, 2010, the capital and surplus of each of our international insurance subsidiaries was above the minimum regulatory thresholds.

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

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. Historically, 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. We have no material commodity risk.

120  |

Credit risk is the potential loss resulting from adverse changes in an issuer’s ability to repay its debt obligations. Beginning in 2008 and continuing through the first half of 2009, there were significant disruptions in the financial markets. These market disruptions resulted in a lack of liquidity within the credit markets, which increased credit risk in the financial markets and resulted in the widening of credit spreads. Net unrealized investment gains on fixed maturities were $174.2 million at December 31, 2010 compared to net unrealized investment gains on fixed maturities of $150.4 million at December 31, 2009 and net unrealized investment losses on fixed maturities of $129.8 million at December 31, 2008. The favorable change in the estimated fair value of our fixed maturity portfolio during both 2010 and 2009 was due in part to decreased credit risk as the financial markets improved and credit spreads narrowed during the latter half of 2009 and into 2010.

During the latter half of 2010, credit spreads on our municipal bond holdings widened, reflecting general concern about the growing number of municipalities experiencing financial difficulties in light of the adverse economic conditions experienced over the past several years. 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 general obligation or revenue bonds related to essential products and services.

We monitor our 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 93% 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 December 31, 2010, approximately 2% 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.

The estimated fair value of our investment portfolio at December 31, 2010 was $8.2 billion, 79% of which was invested in fixed maturities, short-term investments and cash and cash equivalents and 21% of which was invested in equity securities. At December 31, 2009, the estimated fair value of our investment portfolio was $7.8 billion, 82% of which was invested in fixed maturities, short-term investments and cash and cash equivalents and 18% of which was invested in equity securities and investments in affiliates.

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. At December 31, 2010, we did not hold material investments in auction rate securities, loans held for sale or mortgage-backed securities backed by subprime or Alt-A collateral.

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

Equity Price Risk

We invest a portion of shareholder funds in equity securities, which have historically produced higher long-term returns relative to fixed maturities. We seek to invest in profitable companies, with honest and talented management, that exhibit reinvestment opportunities and capital discipline, at reasonable prices. We intend to hold these investments over the long term and focus on long-term total investment return, understanding that the level of unrealized gains or losses on investments may vary from one period to the next. The changes in the estimated fair value of the equity portfolio are presented as a component of shareholders’ equity in accumulated other comprehensive income, net of taxes. See note 2(a) of the notes to consolidated financial statements for disclosure of gross unrealized gains and losses by investment category.

At December 31, 2010, our equity portfolio was concentrated in terms of the number of issuers and industries. Such concentrations can lead to higher levels of price volatility. At December 31, 2010, our ten largest equity holdings represented $941.9 million, or 55%, of the equity portfolio. Investments in the property and casualty insurance industry represented $413.4 million, or 24%, of our equity portfolio at December 31, 2010. Our investments in the property and casualty insurance industry included a $230.1 million investment in the common stock of Berkshire Hathaway Inc., a company whose subsidiaries engage in a number of diverse business activities in addition to insurance. We have investment guidelines that set limits on the amount of equity securities our insurance subsidiaries can hold.

The following table summarizes our equity price risk and shows the effect of a hypothetical 35% increase or decrease in market prices as of December 31, 2010 and 2009. The selected hypothetical changes do not indicate what could be the potential best or worst case scenarios.

(dollars in millions)	Estimated Fair Value		Hypothetical Price Change		Estimated Fair Value after Hypothetical Change in Prices		Estimated Hypothetical Percentage Increase (Decrease) in Shareholders’ Equity
As of December 31, 2010
Equity Securities	$	1,722		35% increase	$	2,325		12.5	%

Interest Rate Risk

Our fixed maturity investments and borrowings are subject to interest rate risk. Increases and decreases in interest rates typically result in decreases and increases, respectively, in the fair value of these financial instruments.

Approximately two-thirds of our investable assets come from premiums paid by policyholders. These funds are invested predominantly in high quality corporate, government and municipal bonds with relatively short durations. The fixed maturity portfolio, including short-term investments and cash and cash equivalents, has an average duration of 3.5 years and an average rating of “AA.” See note 2(c) of the notes to consolidated financial statements for disclosure of contractual maturity dates of our fixed maturity portfolio. The changes in the estimated fair value of the fixed maturity portfolio are presented as a component of shareholders’ equity in accumulated other comprehensive income, net of taxes.

We work to manage the impact of interest rate fluctuations on our fixed maturity portfolio. The effective duration of the fixed maturity portfolio is managed with consideration given to the estimated duration of our liabilities. We have investment guidelines that limit the maximum duration and maturity of the fixed maturity portfolio.

We use a commercially available model to estimate the effect of interest rate risk on the fair values of our fixed maturity portfolio and borrowings. The model estimates the impact of interest rate changes on a wide range of factors including duration, prepayment, put options and call options. Fair values are estimated based on the net present value of cash flows, using a representative set of possible future interest rate scenarios. The model requires that numerous assumptions be made about the future. To the extent that any of the assumptions are invalid, incorrect estimates could result. The usefulness of a single point-in-time model is limited, as it is unable to accurately incorporate the full complexity of market interactions.

Foreign Currency Exchange Rate Risk

We have foreign currency exchange rate risk associated with our assets and liabilities. We manage this risk primarily by matching assets and liabilities in each foreign currency as closely as possible. To assist with the matching of assets and liabilities in foreign currencies, we periodically purchase foreign currency forward contracts and we purchase or sell foreign currencies in the open market. Our forward contracts are generally designated as specific hedges for financial reporting purposes. As such, realized and unrealized gains and losses on these hedges are recorded as currency translation adjustments and are part of other comprehensive income (loss). Our contracts generally have maturities of three months.

At December 31, 2010 and 2009, approximately 89% and 87%, respectively, of our invested assets were denominated in United States Dollars. At those dates, the largest foreign currency exposure was United Kingdom Sterling. If Sterling assets and liabilities had been mismatched by 10% and the United States Dollar/United Kingdom Sterling exchange rate increased by 25%, shareholders’ equity at December 31, 2010 and 2009 would have changed by approximately $10.8 million and $14.3 million, respectively. If Sterling assets and liabilities had been mismatched by 10% and the United States Dollar/United Kingdom Sterling exchange rate decreased by 25%, shareholders’ equity at December 31, 2010 and 2009 would have changed by approximately $8.8 million and $11.7 million, respectively. The selected hypothetical changes do not indicate what could be the potential best or worst case scenarios.

Impact of Inflation

Property and casualty insurance premiums are established before the amount of losses and loss adjustment expenses, or the extent to which inflation may affect such expenses, is known. Consequently, in establishing premiums, we attempt to anticipate the potential impact of inflation. We also consider inflation in the determination and review of reserves for losses and loss adjustment expenses since portions of these reserves are expected to be paid over extended periods of time. The importance of continually reviewing reserves is even more pronounced in periods of extreme inflation.

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

Controls and Procedures

As of December 31, 2010, 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.

Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, we carried out an evaluation, under the supervision and with the participation of our management, including the CEO and the CFO, of the effectiveness of our internal control over financial reporting as of December 31, 2010. See Management’s Report on Internal Control over Financial Reporting and our independent registered public accounting firm’s attestation report on the effectiveness of our internal control over financial reporting beginning on page 85.

During the fourth quarter of 2010, we completed the implementation of a new billing and collections system that provides a single billing and collections solution for our wholesale insurance operations.

There were no other changes in our internal control over financial reporting during the fourth quarter of 2010 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.

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 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;

• we are legally required in certain instances to offer terrorism insurance and actively manage our exposure; however, if there is a covered terrorist attack, we could sustain material losses;

• the impact of the events of September 11, 2001 will depend on the resolution of on-going insurance coverage litigation and arbitrations;

• the frequency and severity of catastrophic events (including earthquakes and weather-related catastrophes) is 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 or other adverse weather-related activity;

• changing legal and social trends and inherent uncertainties (including but not limited to those uncertainties associated with our asbestos and environmental reserves) in the loss estimation process can adversely impact the adequacy of loss reserves and the allowance for reinsurance recoverables;

• we have exposure to losses associated with the adverse conditions in the residential mortgage market, principally with respect to loan transactions that occurred before the end of 2008; our loss reserves are based on judgments about the future performance of the underlying loans; however, continued weakness or other disruptions in the residential housing markets may result in additional loss experience and require strengthening of our loss reserves;

• adverse developments in insurance coverage litigation could result in material increases in our estimates of loss reserves;

• the loss estimation process may become more uncertain if we experience a period of rising inflation;

• the costs and availability of reinsurance may impact our ability to write certain lines of business;

• industry and economic conditions can affect the ability and/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;

Markel Corporation & Subsidiaries

MANAGEMENT’S DISCUSSION & ANALYSIS

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

• economic conditions, 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 fixed maturities and equity securities, as well as the carrying value of other assets and liabilities, and this impact may be heightened by market volatility;

• economic conditions, changes in government support for education, healthcare and infrastructure projects and foreign currency exchange rates, among other factors, may adversely affect the markets served by our non-insurance operations and negatively impact their revenues and profitability;

• we have substantial investments in municipal bonds (approximately $2.8 billion at December 31, 2010) and, although no more than 10% of our municipal bond portfolio is tied to any one state, widespread defaults could adversely affect our results of operations and financial condition;

• we cannot predict the extent and duration of the current economic slowdown; the effects of government intervention into the markets to address the financial crisis of 2008 and 2009 (including, among other things, financial stability and recovery initiatives; changes in tax policy; and the effects of the Dodd-Frank Wall Street Reform and Consumer Protection Act and regulations adopted thereunder); and their combined impact on our industry, business and investment portfolio;

• we cannot predict the impact of U.S. health care reform legislation and regulations under that legislation on our business;

• our Atlas system and business process initiative may take longer to implement and cost more than we anticipate and may not achieve all of its objectives;

• we have recently completed a number of acquisitions and may engage in additional acquisition activity in the future, which may increase operational and control risks for a period of time;

• loss of services of any executive officers could impact our operations; and

• adverse changes in our assigned financial strength or debt ratings could 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.
