NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

(1) General

The accompanying unaudited consolidated financial statements of W. R. Berkley Corporation and its subsidiaries (the “Company”) have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information. Accordingly, they do not include all the information and notes required by GAAP for annual financial statements. The unaudited consolidated financial statements reflect all adjustments, consisting only of normal recurring items, which are necessary to present fairly the Company’s financial position and results of operations on a basis consistent with the prior audited consolidated financial statements. Operating results for interim periods are not necessarily indicative of the results that may be expected for the year. All significant intercompany accounts and transactions have been eliminated. The preparation of financial statements requires the use of management estimates. For further information related to a description of areas of judgment and estimates and other information necessary to understand the Company’s financial position and results of operations, refer to the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. Reclassifications have been made in the 2014 financial statements as originally reported to conform to the presentation of the 2015 financial statements.

The income tax provision has been computed based on the Company’s estimated annual effective tax rate. The effective tax rate for the quarter differs from the federal income tax rate of 35% principally because of tax-exempt investment income.

(2) Per Share Data

The Company presents both basic and diluted net income per share (“EPS”) amounts. Basic EPS is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Diluted EPS is based upon the weighted average number of common and common equivalent shares outstanding during the period and is calculated using the treasury stock method for stock incentive plans. Common equivalent shares are excluded from the computation in periods in which they have an anti-dilutive effect.

The weighted average number of common shares used in the computation of basic and diluted earnings per share was as follows:

	For the Three Months		For the Six Months
	Ended June 30,		Ended June 30,
(In thousands)	2015	2014	2015	2014
Basic	123,781	127,668	124,869	128,765
Diluted	129,988	133,304	131,228	134,323

(3) Recent Accounting Pronouncements

All recently issued but not yet effective accounting and reporting standards are either not applicable to the Company or are not expected to have a material impact on the Company.

(4) Acquisitions/Dispositions

In 2014, the Company acquired a specialty property and casualty insurance distribution company for $83 million. The fair values of the assets acquired and liabilities assumed have been estimated based on a valuation prepared by a third party. The estimated useful lives of the intangible assets acquired range from 7 years to 15 years, with approximately $10 million having an indefinite life.

In 2014, the Company sold an aviation-related business for $16 million. The business had a net carrying value of $15 million.

The following table summarizes the estimated fair value of net assets acquired and liabilities assumed for business combinations completed in 2014:

(9) Arbitrage Trading Account

At June 30, 2015 and December 31, 2014, the carrying value of the arbitrage trading account was $830 million and $451 million, respectively. The primary focus of the trading account is merger arbitrage. Merger arbitrage is the business of investing in the securities of publicly held companies which are the targets in announced tender offers and mergers. Arbitrage investing differs from other types of investing in its focus on transactions and events believed likely to bring about a change in value over a relatively short time period (usually four months or less). The Company believes that this makes merger arbitrage investments less vulnerable to changes in general financial market conditions.

Loans receivable in non-accrual status were $9.5 million and $14.2 million as of June 30, 2015 and December 31, 2014, respectively.

The Company monitors the performance of its loans receivable and assesses the ability of the borrower to pay principal and interest based upon loan structure, underlying property values, cash flow and related financial and operating performance of the property and market conditions. Loans receivable with a potential for default are further assessed using discounted cash flow analysis and comparable cost and sales methodologies, if appropriate.

The real estate loans are secured by commercial real estate primarily located in Arizona, Maryland, New York and Texas. These loans generally earn interest at floating LIBOR-based interest rates and have maturities (inclusive of extension options) through August 2025. The commercial loans are with small business owners who have secured the related financing with the assets of the business. Commercial loans generally earn interest on a fixed basis and have varying maturities not exceeding 10 years.

The Company utilizes a risk rating system to assign a risk to each of its real estate loans. The loan rating system takes into consideration credit quality indicators including loan to value ratios, which compare the outstanding loan amount to the estimated value of the property, the borrower’s financial condition and performance with respect to loan terms, the Company’s position in the capital structure, and the overall leverage in the capital structure. Based on this rating system, none of the real estate loans were considered to be impaired at June 30, 2015, and accordingly, the Company determined that a specific valuation allowance was not required.

Fixed Maturity Securities – A summary of the Company’s non-investment grade fixed maturity securities that were in an unrealized loss position at June 30, 2015 is presented in the table below:

($ in thousands)	Number of Securities	Aggregate Fair Value		Gross Unrealized Loss
Mortgage-backed securities	7	$	24,150	$	1,605
Corporate	13	90,216		2,486
Total	20	$	114,366	$	4,091

For OTTI of fixed maturity securities that management does not intend to sell or, more likely than not, would not be required to sell, the portion of the decline in value considered to be due to credit factors is recognized in earnings and the portion of the decline in value considered to be due to non-credit factors is recognized in other comprehensive income. For the six months ended June 30, 2015 and 2014, there were no changes in the portion of impairments recognized in earnings for those securities that have been impaired due to both credit factors and non-credit factors.

The Company has evaluated its fixed maturity securities in an unrealized loss position and believes the unrealized losses are due primarily to temporary market and sector-related factors rather than to issuer-specific factors. None of these securities are delinquent or in default under financial covenants. Based on its assessment of these issuers, the Company expects them to continue to meet their contractual payment obligations as they become due and does not consider any of these securities to be OTTI.

16

Equity Securities – At June 30, 2015, there were eight equity securities in an unrealized loss position, with an aggregate fair value of $83.6 million and a gross unrealized loss of $15 million. Three of these equity securities are preferred stocks that are rated non-investment grade with an aggregate fair value of $3.6 million and a gross unrealized loss of $1.2 million. Based upon management’s view of the underlying value of these securities, the Company does not consider these equity securities to be OTTI.

Loans Receivable – The Company monitors the performance of its loans receivable, including current market conditions for each loan and the ability to collect principal and interest. For loans where the Company determines it is probable that the contractual terms will not be met, an analysis is performed and a valuation reserve is established, if necessary, with a charge to earnings. Loans receivable are reported net of a valuation reserve of $2 million and $3 million at June 30, 2015 and December 31, 2014, respectively.

(16)Fair Value Measurements

The Company’s fixed maturity and equity securities classified as available for sale and its trading account securities are carried at fair value. Fair value is defined as “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.” The Company utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels, as follows:

Level 1 - Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.  

Level 2 - Quoted prices for similar assets or valuations based on inputs that are observable.

Level 3 - Estimates of fair value based on internal pricing methodologies using unobservable inputs. Unobservable inputs are only used to measure fair value to the extent that observable inputs are not available.

Substantially all of the Company’s fixed maturity securities were priced by independent pricing services. The prices provided by the independent pricing services are estimated based on observable market data in active markets utilizing pricing models and processes, which may include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, sector groupings, matrix pricing and reference data. The pricing services may prioritize inputs differently on any given day for any security based on market conditions, and not all inputs are available for each security evaluation on any given day. The pricing services used by the Company have indicated that they will only produce an estimate of fair value if objectively verifiable information is available. The determination of whether markets are active or inactive is based upon the volume and level of activity for a particular asset class. The Company reviews the prices provided by pricing services for reasonableness and periodically performs independent price tests of a sample of securities to ensure proper valuation.

If prices from independent pricing services are not available for fixed maturity securities, the Company estimates the fair value. For Level 2 securities, the Company utilizes pricing models and processes which may include benchmark yields, sector groupings, matrix pricing, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, bids, offers and reference data. Where broker quotes are used, the Company generally requests two or more quotes and sets a price within the range of quotes received based on its assessment of the credibility of the quote and its own evaluation of the security. The Company generally does not adjust quotes received from brokers. For securities traded only in private negotiations, the Company determines fair value based primarily on the cost of such securities, which is adjusted to reflect prices of recent placements of securities of the same issuer, financial projections, credit quality and business developments of the issuer and other relevant information.

For Level 3 securities, the Company generally uses a discounted cash flow model to estimate the fair value of fixed maturity securities. The cash flow models are based upon assumptions as to prevailing credit spreads, interest rate and interest rate volatility, time to maturity and subordination levels. Projected cash flows are discounted at rates that are adjusted to reflect illiquidity, where appropriate.

(20) Litigation and Contingent Liabilities

In the ordinary course of business, the Company is subject to disputes, litigation and arbitration arising from its insurance and reinsurance businesses.

The Company expects its ultimate liability with respect to such matters will not be material to its financial condition. However, adverse outcomes on such matters are possible, from time to time, and could be material to the Company’s results of operations in any particular financial reporting period.

(21) Business Segments

The Company’s financial results are presented for the following reportable business segments, plus a corporate segment:

• Insurance-Domestic - commercial insurance business, including excess and surplus lines and admitted lines, primarily throughout the United States;

Berkley Corporation is an insurance holding company that is among the largest commercial lines writers in the United States and operates in three business segments: Insurance-Domestic, Insurance-International and Reinsurance-Global. Our decentralized structure provides us with the flexibility to respond quickly and efficiently to local or specific market conditions and to pursue specialty business niches. It also allows us to be closer to our customers in order to better understand their individual needs and risk characteristics. While providing our business units with certain operating autonomy, our structure allows us to capitalize on the benefits of economies of scale through centralized capital, investment, reinsurance, enterprise risk management, and actuarial, financial and corporate legal staff support. The Company’s primary sources of revenues and earnings are its insurance operations and its investments.

An important part of our strategy is to form new operating units to capitalize on various business opportunities. Since 2006, the Company has formed 24 new operating units that are focused on important parts of the economy in the U.S., including healthcare, energy and agriculture, and on growing international markets, including Scandinavia, Australia, the Asia-Pacific region and South America.

The profitability of the Company’s insurance business is affected primarily by the adequacy of premium rates. The ultimate adequacy of premium rates is not known with certainty at the time an insurance policy is issued because premiums are determined before claims are reported. The ultimate adequacy of premium rates is affected mainly by the severity and frequency of claims, which are influenced by many factors, including natural and other disasters, regulatory measures and court decisions that define and change the extent of coverage and the effects of economic inflation on the amount of compensation for injuries or losses. General insurance prices are also influenced by available insurance capacity, i.e., the level of statutory capital and surplus employed in the industry, and the industry’s willingness to deploy that capital.

From 2005 through 2010, the property casualty insurance market was very competitive and insurance rates decreased across most business lines. Although prices have generally increased since the beginning of 2011, the current market is highly competitive and price levels for certain lines of business remain below the prices required for the Company to achieve its long-term return objectives. Part of the Company's strategy is to selectively reduce its business in areas where it believes returns are not adequate. Price changes are reflected in the Company’s results over time as premiums are earned.

The Company’s profitability is also affected by its investment income and investment gains. The Company’s invested assets, which are derived from its own capital and cash flow from its insurance business, are invested principally in fixed maturity securities. The return on fixed maturity securities is affected primarily by general interest rates, as well as the credit quality and duration of the securities. Returns available on fixed maturity investments are at historically low levels. The Company's investment income has been negatively impacted by the low fixed maturity investment returns, and will be further impacted if investment returns remain at this level.

The Company has increasingly invested in equity securities, merger arbitrage securities, investment funds (including energy related funds), private equity, loans and real estate related assets. The Company's investments in investment funds and its other alternative investments have experienced, and the Company expects to continue to experience, greater fluctuations in investment income.

Critical Accounting Estimates

The following presents a discussion of accounting policies and estimates relating to reserves for losses and loss expenses, assumed premiums and other-than-temporary impairments of investments. Management believes these policies and estimates are the most critical to its operations and require the most difficult, subjective and complex judgments.

Reserves for Losses and Loss Expenses.To recognize liabilities for unpaid losses, either known or unknown, insurers establish reserves, which is a balance sheet account representing estimates of future amounts needed to pay claims and related expenses with respect to insured events which have occurred. Estimates and assumptions relating to reserves for losses and loss expenses are based on complex and subjective judgments, often including the interplay of specific uncertainties with related accounting and actuarial measurements. Such estimates are also susceptible to change as significant periods of time may elapse between the occurrence of an insured loss, the report of the loss to the insurer, the ultimate determination of the cost of the loss and the insurer’s payment of that loss.

In general, when a claim is reported, claims personnel establish a “case reserve” for the estimated amount of the ultimate payment based upon known information about the claim at that time. The estimate represents an informed judgment based on general reserving practices and reflects the experience and knowledge of the claims personnel regarding the nature and value of the specific type of claim. Reserves are also established on an aggregate basis to provide for losses incurred but not reported (“IBNR”) to the insurer, potential inadequacy of case reserves and the estimated expenses of settling claims, including legal and

25

other fees and general expenses of administrating the claims adjustment process. Reserves are established based upon the then current legal interpretation of coverage provided.

In examining reserve adequacy, several factors are considered in estimating the ultimate economic value of losses. These factors include, among other things, historical data, legal developments, changes in social attitudes and economic conditions, including the effects of inflation. The actuarial process relies on the basic assumption that past experience, adjusted judgmentally for the effects of current developments and anticipated trends, is an appropriate basis for predicting future outcomes. Reserve amounts are based on management’s informed estimates and judgments using currently available data. As additional experience and other data become available and are reviewed, these estimates and judgments may be revised. This may result in reserve increases or decreases that would be reflected in our results in periods in which such estimates and assumptions are changed.

Reserves do not represent an exact calculation of liability. Rather, reserves represent an estimate of what management expects the ultimate settlement and claim administration will cost. While the methods for establishing reserves are well tested over time, some of the major assumptions about anticipated loss emergence patterns are subject to unanticipated fluctuation. These estimates, which generally involve actuarial projections, are based on management’s assessment of facts and circumstances then known, as well as estimates of trends in claims severity and frequency, judicial theories of liability and other factors, including the actions of third parties which are beyond the Company’s control. These variables are affected by external and internal events, such as inflation and economic volatility, judicial and litigation trends, reinsurance coverage, legislative changes and claim handling and reserving practices, which make it more difficult to accurately predict claim costs. The inherent uncertainties of estimating reserves are greater for certain types of liabilities where long periods of time elapse before a definitive determination of liability is made. Because setting reserves is inherently uncertain, the Company cannot provide assurance that its current reserves will prove adequate in light of subsequent events.

Loss reserves included in the Company’s financial statements represent management’s best estimates based upon an actuarially derived point estimate and other considerations. The Company uses a variety of actuarial techniques and methods to derive an actuarial point estimate for each operating unit. These methods include paid loss development, incurred loss development, paid and incurred Bornhuetter-Ferguson methods and frequency and severity methods. In circumstances where one actuarial method is considered more credible than the others, that method is used to set the point estimate. For example, the paid loss and incurred loss development methods rely on historical paid and incurred loss data. For new lines of business, where there is insufficient history of paid and incurred claims data, or in circumstances where there have been significant changes in claim practices, the paid and incurred loss development methods would be less credible than other actuarial methods. The actuarial point estimate may also be based on a judgmental weighting of estimates produced from each of the methods considered. Industry loss experience is used to supplement the Company’s own data in selecting “tail factors” and in areas where the Company’s own data is limited. The actuarial data is analyzed by line of business, coverage and accident or policy year, as appropriate, for each operating unit.

The establishment of the actuarially derived loss reserve point estimate also includes consideration of qualitative factors that may affect the ultimate losses. These qualitative considerations include, among others, the impact of re-underwriting initiatives, changes in the mix of business, changes in distribution sources and changes in policy terms and conditions. Examples of changes in terms and conditions that can have a significant impact on reserve levels are the use of aggregate policy limits, the expansion of coverage exclusions, whether or not defense costs are within policy limits, and changes in deductibles and attachment points.

The key assumptions used to arrive at the best estimate of loss reserves are the expected loss ratios, rate of loss cost inflation, and reported and paid loss emergence patterns. Expected loss ratios represent management’s expectation of losses at the time the business is written, before any actual claims experience has emerged. This expectation is a significant determinant of the estimate of loss reserves for recently written business where there is little paid or incurred loss data to consider. Expected loss ratios are generally derived from historical loss ratios adjusted for the impact of rate changes, loss cost trends and known changes in the type of risks underwritten. Expected loss ratios are estimated for each key line of business within each operating unit. Expected loss cost inflation is particularly important for the long-tail lines, such as excess casualty, and claims with a high medical component, such as workers’ compensation. Reported and paid loss emergence patterns are used to project current reported or paid loss amounts to their ultimate settlement value. Loss development factors are based on the historical emergence patterns of paid and incurred losses, and are derived from the Company’s own experience and industry data. The paid loss emergence pattern is also significant to excess and assumed workers’ compensation reserves because those reserves are discounted to their estimated present value based upon such estimated payout patterns. Management believes the estimates and assumptions it makes in the reserving process provide the best estimate of the ultimate cost of settling claims and related expenses with respect to insured events which have occurred; however, different assumptions and variables could lead to significantly different reserve estimates.

Loss frequency and severity are measures of loss activity that are considered in determining the key assumptions described in our discussion of loss and loss expense reserves, including expected loss ratios, rate of loss cost inflation and

26

reported and paid loss emergence patterns. Loss frequency is a measure of the number of claims per unit of insured exposure, and loss severity is a measure of the average size of claims. Factors affecting loss frequency include the effectiveness of loss controls and safety programs and changes in economic activity or weather patterns. Factors affecting loss severity include changes in policy limits, retentions, rate of inflation and judicial interpretations.

Another factor affecting estimates of loss frequency and severity is the loss reporting lag, which is the period of time between the occurrence of a loss and the date the loss is reported to the Company. The length of the loss reporting lag affects our ability to accurately predict loss frequency (loss frequencies are more predictable for lines with short reporting lags) as well as the amount of reserves needed for incurred but not reported losses (less IBNR is required for lines with short reporting lags). As a result, loss reserves for lines with short reporting lags are likely to have less variation from initial loss estimates. For lines with short reporting lags, which include commercial automobile, primary workers’ compensation, other liability (claims-made) and property business, the key assumption is the loss emergence pattern used to project ultimate loss estimates from known losses paid or reported to date. For lines of business with long reporting lags, which include other liability (occurrence), products liability, excess workers’ compensation and liability reinsurance, the key assumption is the expected loss ratio since there is often little paid or incurred loss data to consider. Historically, the Company has experienced less variation from its initial loss estimates for lines of businesses with short reporting lags than for lines of business with long reporting lags.

The key assumptions used in calculating the most recent estimate of the loss reserves are reviewed each quarter and adjusted, to the extent necessary, to reflect historical changes, current trends and other factors observed. If the actual level of loss frequency and severity are higher or lower than expected, the ultimate losses will be different than management’s estimate. The following table reflects the impact of changes (which could be favorable or unfavorable) in frequency and severity, relative to our assumptions, on our loss estimate for claims occurring in 2014:

(In thousands)	Frequency (+/-)
Severity (+/-)	1%		5%		10%
1%	$	70,266	$	211,497	$	388,037
5%	211,497		358,222		541,853
10%	388,037		541,853		734,123

Our net reserves for losses and loss expenses of approximately $9.2 billion as of June 30, 2015 relate to multiple accident years. Therefore, the impact of changes in frequency or severity for more than one accident year could be higher or lower than the amounts reflected above.

Approximately $1.4 billion, or 15.6%, of the Company’s net loss reserves as of June 30, 2015 relate to the Reinsurance-Global segment. There is a higher degree of uncertainty and greater variability regarding estimates of assumed loss reserves because those estimates are based, in part, upon information received from ceding companies. If information received from ceding companies is not timely or correct, the Company’s estimate of ultimate losses may not be accurate. Furthermore, due to delayed reporting of claim information by ceding companies, the claim settlement tail for assumed reinsurance is extended. Management considers the impact of delayed reporting in its selection of assumed loss development factors.

Information received from ceding companies is used to set initial expected loss ratios, to establish case reserves and to estimate reserves for incurred but not reported losses on assumed reinsurance business. This information, which is generally provided through reinsurance intermediaries, is gathered through the underwriting process and from periodic claim reports and other correspondence with ceding companies. The Company performs underwriting and claim audits of selected ceding companies to determine the accuracy and completeness of information provided to the Company. The information received from the ceding companies is supplemented by the Company’s own loss development experience with similar lines of business as well as industry loss trends and loss development benchmarks.

___________

(1) Reserves for workers’ compensation and reinsurance are net of an aggregate net discount of $727 million and $746 million as of June 30, 2015 and December 31, 2014, respectively.

The Company evaluates reserves for losses and loss adjustment expenses on a quarterly basis. Changes in estimates of prior year losses are reported when such changes are made. The changes in prior year loss reserve estimates are generally the result of ongoing analysis of recent loss development trends. Original estimates are increased or decreased as additional information becomes known regarding individual claims and aggregate claim trends.

Certain of the Company's insurance and reinsurance contracts are retrospectively rated, whereby the Company collects more or less premiums based on the level of loss activity. For those contracts, changes in loss and loss adjustment expenses for prior years may be fully or partially offset by additional or return premiums.

Net prior year development (i.e, the sum of prior year reserve changes and prior year earned premiums changes) for the six months ended June 30, 2015 and 2014 are as follows:

(In thousands)	2015		2014
Net decrease in prior year loss reserves	$	27,478	$	43,225
Increase in prior year earned premiums	6,645		6,003
Net favorable prior year development	$	34,123	$	49,228

In 2015, favorable prior year development (net of additional and return premiums) was $34 million, and included $28 million for the Insurance-Domestic segment, $3 million for the Insurance-International segment and $3 million for the Reinsurance-Global segment. The favorable development for the Insurance-Domestic segment was primarily attributable to excess and surplus lines business and to accident years 2007 through 2010. The favorable development for excess and surplus lines reflects the continuation of favorable claim frequency trends (i.e., number of reported claims per unit of exposure).

In 2014, favorable reserve development (net of additional and return premiums) of $49 million was primarily related to the Insurance-Domestic segment and was also driven by excess and surplus lines casualty business.

28

Reserve Discount. The Company discounts its liabilities for certain workers’ compensation reserves. The amount of workers’ compensation reserves that were discounted was $2,064 million and $2,187 million at June 30, 2015 and December 31, 2014, respectively. The aggregate net discount for those reserves, after reflecting the effects of ceded reinsurance, was $727 million and $746 million at June 30, 2015 and December 31, 2014, respectively. At June 30, 2015, discount rates by year ranged from 2.0% to 6.5%, with a weighted average discount rate of 4.0%.

Substantially all of discounted workers’ compensation reserves (98% of total discounted reserves at June 30, 2015) are excess workers’ compensation reserves. In order to properly match loss expenses with income earned on investment securities supporting the liabilities, reserves for excess workers’ compensation business are discounted using risk-free discount rates determined by reference to the U.S. Treasury yield curve. These rates are determined annually based on the weighted average rate for the period. Once established, no adjustments are made to the discount rate for that period, and any increases or decreases in loss reserves in subsequent years are discounted at the same rate, without regard to when any such adjustments are recognized. The expected loss and loss expense payout patterns subject to discounting are derived from the Company’s loss payout experience.  

The Company also discounts reserves for certain other long-duration workers’ compensation reserves (representing approximately 2% of total discounted reserves at June 30, 2015), including reserves for quota share reinsurance and reserves related to losses regarding occupational lung disease.  These reserves are discounted at statutory rates permitted by the Department of Insurance of the State of Delaware.

Assumed Reinsurance Premiums. The Company estimates the amount of assumed reinsurance premiums that it will receive under treaty reinsurance agreements at the inception of the contracts. These premium estimates are revised as the actual amount of assumed premiums is reported to the Company by the ceding companies. As estimates of assumed premiums are made or revised, the related amount of earned premiums, commissions and incurred losses associated with those premiums are recorded. Estimated assumed premiums receivable were approximately $65 million at June 30, 2015 and $85 million at December 31, 2014. The assumed premium estimates are based upon terms set forth in reinsurance agreements, information received from ceding companies during the underwriting and negotiation of agreements, reports received from ceding companies and discussions and correspondence with reinsurance intermediaries. The Company also considers its own view of market conditions, economic trends and experience with similar lines of business. These premium estimates represent management’s best estimate of the ultimate amount of premiums to be received under its assumed reinsurance agreements.

Other-Than-Temporary Impairments (OTTI) of Investments. The cost of securities is adjusted where appropriate to include a provision for decline in value which is considered to be other-than-temporary. An other-than-temporary decline is considered to occur in investments where there has been a sustained reduction in fair value and where the Company does not expect the fair value to recover prior to the time of sale or maturity. Since equity securities do not have a contractual cash flow or maturity, the Company considers whether the price of an equity security is expected to recover within a reasonable period of time.

The Company classifies its fixed maturity securities and preferred stocks by credit rating, primarily based on ratings assigned by credit rating agencies. For purposes of classifying securities with different ratings, the Company uses the lower rating if two ratings were assigned and the middle rating if three ratings were assigned, unless the Company’s own analysis indicates that the lower rating is more appropriate. Securities that are not rated by a rating agency are evaluated and classified by the Company on a case-by-case basis.

Fixed Maturity Securities – For securities that we intend to sell or, more likely than not, would be required to sell, a decline in value below amortized cost is considered to be OTTI. The amount of OTTI is equal to the difference between amortized cost and fair value at the balance sheet date. For securities that we do not intend to sell or expect to be required to sell, a decline in value below amortized cost is considered to be an OTTI if we do not expect to recover the entire amortized cost basis of a security (i.e., the present value of cash flows expected to be collected is less than the amortized cost basis of the security).

The portion of the decline in value considered to be a credit loss (i.e., the difference between the present value of cash flows expected to be collected and the amortized cost basis of the security) is recognized in earnings. The portion of the decline in value not considered to be a credit loss (i.e., the difference in the present value of cash flows expected to be collected and the fair value of the security) is recognized in other comprehensive income.

Impairment assessments for structured securities, including mortgage-backed securities and asset-backed securities, collateralized debt obligations and corporate debt, are generally evaluated based on the performance of the underlying collateral under various economic and default scenarios that may involve subjective judgments and estimates by management. Modeling these securities involves various factors, such as projected default rates, the nature and realizable value of the collateral, if any,

29

the ability of the issuer to make scheduled payments, historical performance and other relevant economic and performance factors. If an OTTI determination is made, a discounted cash flow analysis is used to ascertain the amount of the credit impairment.

The following table provides a summary of fixed maturity securities in an unrealized loss position as of June 30, 2015:

($ in thousands)	Number of Securities	Aggregate Fair Value		Unrealized Loss
Unrealized loss less than 20% of amortized cost	451	$	3,522,678	$	62,691
Unrealized loss of 20% or greater of amortized cost:
Less than twelve months	1	342		169
Twelve months and longer	13	49,463		17,723
Total	465	$	3,572,483	$	80,583

A summary of the Company’s non-investment grade fixed maturity securities that were in an unrealized loss position at June 30, 2015 is presented in the table below:

($ in thousands)	Number of Securities	Aggregate Fair Value		Unrealized Loss
Mortgage-backed securities	7	$	24,150	$	1,605
Corporate	13	90,216		2,486
Total	20	$	114,366	$	4,091

The Company has evaluated its fixed maturity securities in an unrealized loss position and believes the unrealized loss is due primarily to temporary market and sector-related factors rather than to issuer-specific factors. None of these securities are delinquent or in default under financial covenants. Based on its assessment of these issuers, the Company expects them to continue to meet their contractual payment obligations as they become due and does not consider any of these securities to be OTTI.

Equity Securities – At June 30, 2015, there were eight equity securities in an unrealized loss position, with an aggregate fair value of $83.6 million and a gross unrealized loss of $15.0 million. Three of these equity securities are preferred stocks that are rated non-investment grade with an aggregate fair value of $3.6 million and a gross unrealized loss of $1.2 million. Based upon management’s view of the underlying value of these securities, the Company does not consider these equity securities to be OTTI.

Loans Receivable – The Company monitors the performance of its loans receivable, including current market conditions for each loan and the ability to collect principal and interest. For loans where the Company determines it is probable that the contractual terms will not be met, an analysis is performed and a valuation reserve is established, if necessary, with a charge to earnings. Loans receivable are reported net of a valuation reserve of $2 million and $3 million at June 30, 2015 and December 31, 2014, respectively.

The Company monitors the performance of its loans receivable and assesses the ability of each borrower to pay principal and interest based upon loan structure, underlying property values, cash flow and related financial and operating performance of the property and market conditions. Loans receivable with a potential for default are further assessed using discounted cash flow analysis and comparable cost and sales methodologies, if appropriate.

Fair Value Measurements.The Company’s fixed maturity and equity securities available for sale and its trading account securities are carried at fair value. Fair value is defined as “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.” The Company utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for similar assets in active markets. Level 3 inputs are unobservable inputs for the asset or liability. Unobservable inputs may only be used to measure fair value to the extent that observable inputs are not available. The fair value of the vast majority of the Company’s portfolio is based on observable data (other than quoted prices) and, accordingly, is classified as Level 2.

In classifying particular financial securities in the fair value hierarchy, the Company uses its judgment to determine whether the market for a security is active and whether significant pricing inputs are observable. The Company determines the existence of an active market by assessing whether transactions occur with sufficient frequency and volume to provide reliable

30

pricing information. The Company determines whether inputs are observable based on the use of such information by pricing services and external investment managers, the uninterrupted availability of such inputs, the need to make significant adjustments to such inputs and the volatility of such inputs over time. If the market for a security is determined to be inactive or if significant inputs used to price a security are determined to be unobservable, the security is categorized in Level 3 of the fair value hierarchy.

Because many fixed maturity securities do not trade on a daily basis, the Company utilizes pricing models and processes which may include benchmark curves, benchmarking of like securities, sector groupings and matrix pricing. Market inputs used to evaluate securities include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data. Quoted prices are often unavailable for recently issued securities that are infrequently traded or securities that are only traded in private transactions. For publicly traded securities for which quoted prices are unavailable, the Company determines fair value based on independent broker quotations and other observable market data. For securities traded only in private negotiations, the Company determines fair value based primarily on the cost of such securities, which is adjusted to reflect prices of recent placements of securities of the same issuer, financial data, projections and business developments of the issuer and other relevant information.

The following is a summary of pricing sources for the Company's fixed maturity securities available for sale as of June 30, 2015:

(In thousands)	Carrying Value		Percent of Total
Pricing source:
Independent pricing services	$	12,030,267	97.9	%

*Less than 0.1%.

Independent pricing services – Substantially all of the Company’s fixed maturity securities available for sale were priced by independent pricing services (generally one U.S. pricing service plus additional pricing services with respect to a limited number of foreign securities held by the Company). The prices provided by the independent pricing services are generally based on observable market data in active markets (e.g., broker quotes and prices observed for comparable securities). The determination of whether markets are active or inactive is based upon the volume and level of activity for a particular asset class. The Company reviews the prices provided by pricing services for reasonableness based upon current trading levels for similar securities. If the prices appear unusual to the Company, they are re-examined and the value is either confirmed or revised. In addition, the Company periodically performs independent price tests of a sample of securities to ensure proper valuation and to verify our understanding of how securities are priced. As of June 30, 2015, the Company did not make any adjustments to the prices provided by the pricing services. Based upon the Company’s review of the methodologies used by the independent pricing services, these securities were classified as Level 2.

Syndicate manager – The Company has a 15% participation in a Lloyd’s syndicate, and the Company’s share of the securities owned by the syndicate is priced by the syndicate’s manager. The majority of the securities are liquid, short duration fixed maturity securities. The Company reviews the syndicate manager’s pricing methodology and audited financial statements and holds discussions with the syndicate manager as necessary to confirm its understanding and agreement with security prices. Based upon the Company’s review of the methodologies used by the syndicate manager, these securities were classified as Level 2.

Observable data – If independent pricing is not available, the Company prices the securities directly. Prices are based on observable market data where available, including current trading levels for similar securities and non-binding quotations from brokers. The Company generally requests two or more quotes. If more than one quote is received, the Company sets a price within the range of quotes received based on its assessment of the credibility of the quote and its own evaluation of the security. The Company generally does not adjust quotes obtained from brokers. Since these securities were priced based on observable data, they were classified as Level 2.

Cash flow model – If the above methodologies are not available, the Company prices securities using a discounted cash flow model based upon assumptions as to prevailing credit spreads, interest rates and interest rate volatility, time to maturity

31

and subordination levels. Discount rates are adjusted to reflect illiquidity where appropriate. These securities were classified as Level 3.

Net Income to Common Stockholders. The following table presents the Company’s net income to common stockholders and net income per diluted share for the six months ended June 30, 2015 and 2014:

(In thousands, except per share data)	2015		2014
Net income to common stockholders	$	241,342	$	349,634
Weighted average diluted shares	131,228		134,323
Net income per diluted share	$	1.84	$	2.60

The Company reported net income of $241 million in 2015 compared to $350 million in 2014. The 31% decrease in net income was primarily due to a decrease in after-tax net investment gains of $75 million and a decrease in after-tax net investment income of $38 million. The number of weighted average diluted shares decreased as a result of the Company’s repurchases of its common stock in 2015 and 2014.

Premiums. Gross premiums written were $3,663 million in 2015, an increase of 2% from $3,578 million in 2014. The growth was due primarily to rate increases. Approximately 79.2% of policies expiring in 2015 were renewed, compared with a 79.3% renewal retention rate for policies expiring in 2014.

Average renewal premium rates (adjusted for change in exposures) increased 1.9% in 2015. However, overall loss costs are also increasing, and current market price levels for certain lines of business remain below the prices required for the Company to achieve its long-term return objectives.

A summary of gross premiums written in 2015 compared with 2014 by line of business within each business segment follows:

• Insurance-Domestic gross premiums increased 5% to $2,831 million in 2015 from $2,695 million in 2014. Gross premiums increased $47 million (6%) for workers' compensation, $41 million (20%) for professional liability, $24 million (3%) for other liability, $19 million (3%), for short-tail lines and $5 million (2%) for commercial auto.

• Insurance-International gross premiums decreased 4% to $520 million in 2015 from $542 million in 2014. Gross premiums increased $16 million (29%) for other liability, $11 million (31%) for workers' compensation and $4 million (7%) for commercial auto. Insurance-International gross premiums decreased $49 million (15%) for short-tail lines and $4 million (8%) for professional liability. In local currency terms, international gross premiums increased 6% in 2015.

• Reinsurance-Global gross premiums decreased 9% to $312 million in 2015 from $341 million in 2014, due to increasingly competitive conditions. Gross premiums written decreased $20 million (9%) for casualty lines and $9 million (8%) for property lines.

Net premiums written were $3,119 million in 2015, an increase of 3% from $3,016 million in 2014. Ceded reinsurance premiums as a percentage of gross written premiums were 15% in 2015 and 16% in 2014.

Premiums earned increased 7% to $2,965 million in 2015 from $2,781 million in 2014. Insurance premiums (including the impact of rate changes) are generally earned evenly over the policy term, and accordingly recent rate increases will be earned over the upcoming quarters. Premiums earned in 2015 are related to business written during both 2015 and 2014. Audit premiums were $73 million in 2015 compared with $60 million in 2014.

Investment expenses	(5,396		)	(6,048		)
Total	$	251,822		$	307,440		3.2		4.0

Net investment income decreased 18% to $252 million in 2015 from $307 million in 2014 due primarily to a $48 million decrease in income from investment funds. The decrease in investment income from investment funds (reported on a one-quarter lag) was primarily due to losses from energy funds, partially offset by higher earnings from real estate funds. Average invested assets, at cost (including cash and cash equivalents) were $15.9 billion in 2015 and $15.2 billion in 2014.

Insurance Service Fees. The Company earns fees from an insurance distribution business and as a servicing carrier of workers' compensation assigned risk plans for certain states. Service fees increased to $72 million in 2015 from $56 million in 2014 as a result of the acquisition of a specialty property and casualty insurance distribution company in late 2014.

Net Realized Gains on Investment Sales. The Company buys and sells securities on a regular basis in order to maximize its total return on investments. Decisions to sell securities are based on management’s view of the underlying fundamentals of specific securities as well as management’s expectations regarding interest rates, credit spreads, currency values and general economic conditions. Net realized gains on investment sales were $47 million in 2015 compared with $162 million in 2014. The realized gains in 2014 included a gain of $86 million from the sale of an investment in a commercial real estate investment fund.

Favorable prior year reserve development (net of premium offsets) was $34 million in 2015 compared with $49 million in 2014, a difference of 0.6 loss ratio point. The loss ratio excluding catastrophe losses and prior year reserve development increased 0.1 points to 60.7% in 2015 from 60.6% in 2014. A summary of loss ratios in 2015 compared with 2014 by business segment follows:

Other Operating Costs and Expenses. Following is a summary of other operating costs and expenses:

(In thousands)	2015		2014
Underwriting expenses	$	982,294	$	928,434
Service expenses	63,458		45,864
Net foreign currency loss	2,509		1,659
Other costs and expenses	76,367		73,359
Total	$	1,124,628	$	1,049,316

Underwriting expenses are comprised of commissions paid to agents and brokers, premium taxes and other assessments and internal underwriting costs. Underwriting expenses increased 6% compared with an increase in net premiums earned of 7%. The expense ratio (underwriting expenses expressed as a percentage of premiums earned) was 33.1% in 2015, down from 33.4% in 2014, primarily due to higher earned premiums and to the impact of expense reduction initiatives.

Service expenses, which represent the costs associated with the fee-based businesses, increased to $63 million in 2015 from $46 million in 2014 as a result of the acquisition of a specialty property and casualty insurance distribution company in late 2014.

Foreign currency gains and losses result from transactions denominated in a currency other than a company's operating functional currency. Net foreign currency losses were $3 million in 2015 compared to a net foreign currency loss of $2 million in 2014.

Other costs and expenses represent general and administrative expenses of the parent company and other expenses not allocated to business segments, including the cost of certain long-term incentive plans. Other costs and expenses increased to $76 million in 2015 from $73 million in 2014 due primarily to higher compensation costs, including costs relating to long-term incentive plans.

Expenses from Wholly-Owned Investees. Expenses from wholly-owned investees represent costs associated with aviation-related businesses that include (i) cost of goods sold related to aircraft and products sold and services provided, and (ii) general and administrative expenses. Expenses from wholly-owned investees were $188 million in 2015 compared to $193 million in 2014.

Interest Expense. Interest expense was $68 million in 2015 compared with $61 million in 2014. In August 2014, the Company issued $350 million of 4.75% senior notes due 2044. A portion of the proceeds were used to repay $200 million of 5.60% senior notes at maturity on May 15, 2015.

Income Taxes. The effective income tax rate was 30% in 2015 compared to 32% in 2014. The effective income tax rate differs from the federal income tax rate of 35% primarily because interest on the Company's state and local bonds is taxed at a lower rate. The decrease in the effective tax rate in 2015 compared with 2014 is due to lower income from investment funds and investment gains, which are generally taxed at the 35% federal income tax rate.

The Company has not provided U.S. deferred income taxes on the undistributed earnings of approximately $55 million of its non-U.S. subsidiaries since these earnings are intended to be permanently reinvested in the non-U.S. subsidiaries. However, in the future, if such earnings were distributed to the Company, taxes of approximately $2.6 million, assuming all tax credits are realized, would be payable on such undistributed earnings and would be reflected in the tax provision for the year in which these earnings are no longer intended to be permanently reinvested in the foreign subsidiary.

Investments

As part of its investment strategy, the Company establishes a level of cash and highly liquid short-term and intermediate-term securities that, combined with expected cash flow, it believes is adequate to meet its payment obligations. Due to the historically low fixed maturity investment returns, the Company has increasingly invested in equity securities, merger arbitrage securities, investment funds, private equity, loans and real estate related assets. The Company's investments in investment funds and its other alternative investments have experienced, and the Company expects to continue to experience, greater fluctuations in investment income.

The Company also attempts to maintain an appropriate relationship between the average duration of the investment portfolio and the approximate duration of its liabilities (i.e., policy claims and debt obligations). The average duration of the fixed maturity portfolio was 3.3 years at June 30, 2015 and 3.2 years at December 31, 2014. The Company’s fixed maturity investment portfolio and investment-related assets as of June 30, 2015 were as follows:

Fixed Maturity Securities. The Company’s investment policy with respect to fixed maturity securities is generally to purchase instruments with the expectation of holding them to their maturity. However, management of the available for sale portfolio is considered necessary to maintain an approximate matching of assets and liabilities as well as to adjust the portfolio as a result of changes in financial market conditions and tax considerations.

The Company’s philosophy related to holding or selling fixed maturity securities is based on its objective of maximizing total return. The key factors that management considers in its investment decisions as to whether to hold or sell fixed maturity securities are its view of the underlying fundamentals of specific securities as well as its expectations regarding interest rates, credit spreads and currency values. In a period in which management expects interest rates to rise, the Company may sell longer duration securities in order to mitigate the impact of an interest rate rise on the fair value of the portfolio. Similarly, in a period in which management expects credit spreads to widen, the Company may sell lower quality securities, and in a period in which management expects certain foreign currencies to decline in value, the Company may sell securities denominated in those foreign currencies. The sale of fixed maturity securities in order to achieve the objective of maximizing total return may result in realized gains; however, there is no reason to expect these gains to continue in future periods.

At June 30, 2015, investments in foreign government fixed maturity securities (which are generally held by the Company's foreign operations) were as follows:

(In thousands)	Carrying Value
Australia	$	244,374
United Kingdom	188,127
Canada	162,441
Argentina	160,430

(1) Supranational represents investments in the North American Development Bank, European Investment Bank and Inter-American Development Bank.

Equity Securities. Equity securities primarily represent investments in high-dividend yielding common and preferred stocks issued by large market capitalization companies.

Investment Funds. At June 30, 2015, the carrying value of investment funds was $1,124 million, including investments in real estate funds of $507 million, energy funds of $114 million and arbitrage funds of $73 million. Investment funds are primarily reported on a one-quarter lag.

Real Estate. Real estate is directly owned property held for investment. At June 30, 2015, real estate properties in operation included a long-term ground lease in Washington D.C. and an office building in West Palm Beach, Florida. In addition, there are three properties under development: an office building in London, a mixed-use project in Washington D.C. and an office complex in New York City. The Company expects to fund further development costs for these projects with a combination of its own funds and external financing.

Arbitrage Trading Account. The arbitrage trading account is comprised of direct investments in arbitrage securities. Merger arbitrage is the business of investing in the securities of publicly held companies that are the targets in announced tender offers and mergers.

Loans Receivable. Loans receivable, which are carried at amortized cost, had an aggregate cost of $259 million and an aggregate fair value of $262 million at June 30, 2015. The amortized cost of loans receivable is net of a valuation allowance of $2 million as of June 30, 2015. Loans receivable include real estate loans of $175 million that are secured by commercial real estate located primarily in Arizona, Maryland, New York and Texas. Real estate loans receivable generally earn interest at floating LIBOR-based interest rates and have maturities (inclusive of extension options) through August 2025. Loans

42

receivable include commercial loans of $84 million that are secured by business assets and have fixed interest rates with varying maturities not exceeding 10 years.

Market Risk. The fair value of the Company’s investments is subject to risks of fluctuations in credit quality and interest rates. The Company uses various models and stress test scenarios to monitor and manage interest rate risk. The Company attempts to manage its interest rate risk by maintaining an appropriate relationship between the average duration of the investment portfolio and the approximate duration of its liabilities (i.e., policy claims and debt obligations). The average duration for the fixed maturity portfolio was 3.3 years at June 30, 2015 and 3.2 years at December 31, 2014. In addition, the fair value of the Company’s international investments is subject to currency risk. The Company attempts to manage its currency risk by matching its foreign currency assets and liabilities where considered appropriate.

Liquidity and Capital Resources

Cash Flow. Cash flow provided from operating activities increased to $333 million in the first six months of 2015 from $255 million in the comparable period in 2014, primarily due to the timing of tax payments, premium collections and expense payments.

The Company's insurance subsidiaries' principal sources of cash are premiums, investment income, service fees and proceeds from sales and maturities of portfolio investments. The principal uses of cash are payments for claims, taxes, operating expenses and dividends. The Company expects its insurance subsidiaries to fund the payment of losses with cash received from premiums, investment income and fees. The Company targets an average duration for its investment portfolio that is within one year of the average duration of its liabilities so that portions of its investment portfolio mature throughout the claim cycle and are available for the payment of claims if necessary. In the event operating cash flow and proceeds from maturities and prepayments of fixed income securities are not sufficient to fund claim payments and other cash requirements, the remainder of the Company's cash and investments is available to pay claims and other obligations as they become due. The Company's investment portfolio is highly liquid, with approximately 81% invested in cash, cash equivalents and marketable fixed maturity securities as of June 30, 2015. If the sale of fixed maturity securities were to become necessary, a realized gain or loss equal to the difference between the cost and sales price of securities sold would be recognized.

Debt. At June 30, 2015, the Company had senior notes, subordinated debentures and other debt outstanding with a carrying value of $2,184 million and a face amount of $2,208 million. The maturities of the outstanding debt are $2 million in 2015, $37 million in 2016, $40 million in 2017, $450 million in 2019, $300 million in 2020, $427 million in 2022, $2 million in 2029, $250 million in 2037, $350 million in 2044 and $350 million in 2053.

In August 2014, the Company issued $350 million of 4.75% senior notes due 2044. A portion of the proceeds was used to repay $200 million of 5.60% senior notes at maturity on May 15, 2015. In addition, in May 2015 the Company repaid $71 million of debt that it had assumed in 2014 in conjunction with the purchase of an office building in West Palm Beach, Florida.

Equity. At June 30, 2015, total common stockholders’ equity was $4.5 billion, common shares outstanding were approximately 122 million and stockholders’ equity per outstanding share was $36.76. During the six months ended June 30, 2015, the Company repurchased 4,395,912 shares of its common stock for $218 million.

In June 2015, the Board of Directors increased the Company's share repurchase authorization to 10 million shares of common stock, of which 9,353,091 remain available as of June 30, 2015. Repurchases may be made by the Company from time to time at prevailing prices in the open market in privately negotiated transactions, subject to market conditions and other factors.

Total Capital.Total capitalization (equity, debt and subordinated debentures) was $6.7 billion at June 30, 2015. The percentage of the Company’s capital attributable to debt and subordinated debentures was 33% at June 30, 2015 and 35% at December 31, 2014.
