Notes to Interim Consolidated Financial Statements (unaudited)
1. GENERAL
     The accompanying consolidated financial statements should be read in conjunction with the following notes and with the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2005. Reclassifications have been made in the 2005 financial statements as originally reported to conform them to the presentation of the 2006 financial statements.
     The income tax provision has been computed based on the Company’s estimated annual effective tax rate, which differs from the federal income tax rate of 35% principally because of tax-exempt investment income.
     The Company presents both basic and diluted earnings per share (EPS) amounts. Basic EPS is calculated by dividing net income by weighted average number of common shares outstanding during the year. Diluted EPS is based upon the weighted average number of common and common equivalent shares outstanding during the year 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. Stock options for which the exercise price exceeds the average market price over the period have an anti-dilutive effect on EPS and, accordingly, are excluded from the calculation. Per share amounts have been adjusted to reflect the 3-for-2 common stock split effected April 4, 2006.
     In the opinion of management, the financial information reflects all adjustments that are necessary for a fair presentation of financial position and results of operations for the interim periods. Seasonal weather variations and natural and man-made catastrophes can have a significant impact on the results of any one or more reporting periods.
2. RECENT ACCOUNTING PRONOUNCEMENTS
     In June 2006, the Financial Accounting Standards Board (the “FASB”) issued interpretation No. 48 (“FIN 48”), Accounting for Uncertainty in Income Taxes. This new interpretation of Statement of Financial Accounting Standards (“FAS”) No. 109 establishes a new accounting model for income tax reserves and contingencies. The adoption of FIN 48 will not have a material impact on the Company’s financial condition or results of operations.
3. COMPREHENSIVE INCOME
     The following is a reconciliation of comprehensive income (dollars in thousands):

4. STOCK-BASED COMPENSATION
     Effective January 1, 2003, the Company adopted the fair value recognition provisions of FAS 123, “Accounting for Stock-Based Compensation”. The fair value provisions of FAS 123 were applied prospectively to all employee awards granted, modified, or settled on or after January 1, 2003. In December 2004, the FASB issued FAS 123R, “Share-Based Payment”, which the Company adopted on January 1, 2006. Under FAS 123R, the cost resulting from all share-based payment transactions with employees, including those awarded prior to January 1, 2003, are recognized in the financial statements using a fair-value-based measurement method. The adoption of FAS 123R resulted in an increase in pretax stock based compensation expense of $0.9 million for the six months ended June 30, 2006.
     The following table illustrates the pro forma effect on net income and earnings per share as if FAS 123R had been adopted on January 1, 2005 (dollars in thousands, except per share data).

7. INDUSTRY SEGMENTS
     The Company’s operations are presently conducted in five segments of the insurance business: specialty lines of insurance, regional property casualty insurance, alternative markets, reinsurance and international.
     Our specialty segment underwrites complex and sophisticated third-party liability risks, principally within the excess and surplus lines. The primary lines of business are premises operations, products liability, commercial automobile, professional liability and property lines. The companies within the segment are divided along the different customer bases and product lines that they serve. The specialty units deliver their products through a variety of distribution channels depending on the customer base and particular risks insured. The customers in this segment are highly diverse.
     Our regional segment provides commercial insurance products to customers primarily in 38 states. Key clients of this segment are small-to-mid-sized businesses and state and local governmental entities. The regional subsidiaries are organized geographically, which provides them with the flexibility to adapt to local market conditions, while enjoying the superior administrative capabilities and financial strength of the Company. The regional operations are conducted through four geographic regions based on markets served: Midwest, New England, Southern (excluding Florida) and Mid Atlantic.

7. INDUSTRY SEGMENTS (continued)
     Our alternative markets operations specialize in developing, insuring, reinsuring and administering self-insurance programs and other alternative risk transfer mechanisms. Our clients include employers, employer groups, insurers, and alternative market funds seeking less costly, more efficient ways to manage exposure to risks. In addition to providing insurance, the alternative markets segment also provides a wide variety of fee-based services, including consulting and administrative services.
     Our reinsurance operations specialize in underwriting property casualty reinsurance on both a treaty and a facultative basis. The principal reinsurance units are facultative reinsurance, which writes individual certificates and program facultative business, treaty reinsurance, which functions as a traditional reinsurer in specialty and standard reinsurance lines, and Lloyd’s reinsurance, which writes property and casualty reinsurance through Lloyd’s.
     Our international segment offers professional indemnity and other lines in the U.K. and Spain, commercial and personal property casualty insurance in Argentina and Brazil and savings and endowment policies to pre-fund education costs in the Philippines.
     The accounting policies of the segments are the same as those described in the summary of significant accounting policies in the Company’s Annual Report on Form 10-K for the year ended December 31, 2005. Income tax expense and benefits are calculated based upon the Company’s effective tax rate.
     Summary financial information about the Company’s operating segments is presented in the following table. Net income by segment consists of revenues less expenses related to the respective segment’s operations, including allocated investment income. Identifiable assets by segment are those assets used in or allocated to the operation of each segment.

8. COMMITMENTS, LITIGATION AND CONTINGENT LIABILITIES
     The Company’s subsidiaries are subject to disputes, including litigation and arbitration, arising in the ordinary course of their insurance and reinsurance businesses. The Company’s estimates of the costs of settling such matters are reflected in its aggregate reserves for losses and loss expenses, and the Company does not believe that the ultimate outcome of such matters will have a material adverse effect on its financial condition or results of operations. However, adverse outcomes are possible and could negatively impact the Company’s financial condition and results of operations.

Item 2.   Management’s Discussion and Analysis of Financial Condition and Results of Operations
Overview
     W. R. Berkley Corporation is an insurance holding company that is among the largest commercial lines writers in the United States and operates in five business segments: specialty insurance, regional property casualty insurance, alternative markets, reinsurance and international. The Company’s primary sources of revenues and earnings are insurance and investments.
     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 a property casualty 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 due for injuries or losses. General insurance prices are also influenced by available insurance capacity, i.e., the level of policyholders’ surplus employed in the industry, and the industry’s willingness to deploy that capital.
     An insurer’s profitability is also affected by its investment income. 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 and the credit quality and duration of the securities. The Company also invests in equity securities, including equity securities related to merger arbitrage and convertible arbitrage strategies.
Critical Accounting Estimates
     The following presents a discussion of accounting policies and estimates relating to reserves for losses and loss expenses and assumed premiums. 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. 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 yet reported to the insurer, potential inadequacy of case reserves and the estimated expenses of settling claims, including legal and other fees and general expenses of administrating the claims adjustment process. Reserves are established based upon the then current legal interpretation of coverage provided.

Table of Contents

     In examining reserve adequacy, several factors are considered in addition to the economic value of losses. These factors include 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 necessarily 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 the 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 future 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 internal and external events, such as inflation and economic volatility, judicial and litigation trends, reinsurance coverage and legislative changes, 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 assure 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 and are based upon an actuarially derived point estimate. 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 ultimate losses and 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 increases, 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 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 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 (“IBNR”) (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, commercial multi-peril business, 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 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. For example, as of December 31, 2005, initial loss estimates for accident years 1996 through 2004 were increased by an average of 6% for lines with short reporting lags and by an average of 37% for lines with long reporting lags. For the latest accident year ended December 31, 2005, initial loss estimates were $1.6 billion for lines with short reporting lags and $0.9 billion for lines 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. For example, in 2005 loss reserves for our commercial, transportation business were increased to reflect an observed trend of higher severity losses, and loss reserves for our California workers’ compensation business were decreased to reflect an observed trend of lower severity losses following the enactment of legislative reforms.

     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 on our loss estimate for claims occurring in 2005 (dollars in thousands):
                         
    Frequency (+/-)

     Our net reserves for losses and loss expenses of $6.4 billion as of June 30, 2006 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 $1.6 billion, or 25%, of the Company’s net loss reserves relate to assumed reinsurance business. 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. 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.

     For the six months ended June 30, 2006, the Company reported losses and loss expenses of $1.4 billion, of which $14 million represented an increase in estimates for claims occurring in prior years. The estimates for claims occurring in prior years were increased by $31 million for assumed reinsurance and decreased by $17 million for primary business. On an accident year basis, the change in prior year reserves is comprised of an increase in estimates for claims occurring in accident years prior to 2003 that was partially offset by a decrease in estimates for claims occurring in accident years 2004 and 2005.
     Case reserves for primary business increased 6% to $1.8 billion as a result of a 4% increase in the number of outstanding claims and a 2% increase in the average case reserve per claim. Reserves for incurred but not reported losses for primary business increased 12% to $3.0 billion at June 30, 2006 from $2.6 billion at December 31, 2005. Prior year reserves decreased by $25 million for the alternative markets segment and increased by $5 million and $3 million, respectively, for the regional and specialty segments. By line of business, prior year reserves decreased by $25 million and $3 million, respectively, for workers’ compensation and general liability and increased by $3 million and $8 million, respectively, for commercial automobile and property lines. The decrease in worker’s compensation prior year reserves reflects the favorable impact of workers’ compensation reforms in California on loss cost trends.
     Case reserves for reinsurance business decreased 5% to $655 million at June 30, 2006 from $687 million at December 31, 2005. Reserves for incurred but not reported losses for reinsurance business increased 21% to $979 million at June 30, 2006 from $810 million at December 31, 2005. Prior year reserves increased $31 million as losses reported by ceding companies for those years were higher than expected. The Company sets its initial loss estimates based principally upon information obtained during the underwriting process and adjusts these estimates as losses are reported by ceding companies and additional information becomes available.

     Premium Estimates. 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 premium, commissions and incurred losses associated with those premiums are recorded. Estimated assumed premiums receivable were approximately $142 million and $90 million at June 30, 2006 and December 31, 2005, respectively. The assumed premium estimates are based upon terms set forth in the reinsurance agreement, information received from ceding companies during the underwriting and negotiation of the agreement, 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 premiums to be received under its assumed reinsurance agreements.
     The Company’s policy is to recognize earned but unbilled audit premiums when they are reliably determinable. As of June 30, 2006 and December 31, 2005, the Company reported an accrual for earned but unbilled audit premiums receivable of $61 million and $47 million, respectively.

     The following table presents the Company’s net income and net income per share for the six months ended June 30, 2006 and 2005 (amounts in thousands, except per share data):
                 
    2006   2005
 
Net income
  $ 327,154     $ 254,950  
Weighted average diluted shares
    202,450       199,915  
Net income per diluted share
  $ 1.62     $ 1.28  
 
     The increase in net income in 2006 compared with 2005 reflects higher investment income and higher profits from underwriting activity. The increase in investment income was the result of an increase in average invested assets as well as an increase in the average yield on investments. The improvement in underwriting results is attributable to a 9% increase in premiums earned and a 0.7 percentage point decrease in the expense ratio (underwriting expenses experienced as a percentage of premiums earned).
     Gross Premiums Written. Gross premiums written were $2.8 billion in 2006, up 6% from 2005. While prices increased significantly in 2002 and 2003, the Company experienced an increased level of price competition in 2004 and 2005. This trend continued in 2006 with price levels for renewal business declining approximately 1% as compared with the prior year period.
     Gross premiums for the regional and alternative markets segments include premiums written on behalf of assigned risk plans managed by the Company. The assigned risk premiums are fully reinsured by the respective state-sponsored assigned risk plans.
     A summary of gross premiums written in 2006 compared with 2005 by business segment follows:
    Specialty gross premiums increased by 4% to $996 million in 2006 from $957 million in 2005. The number of new and renewal policies issued in 2006, net of policy cancellations, increased 2%. Average prices for renewal policies, adjusted for changes in exposure, decreased 1%. Gross premiums written increased 10% for premises operations, 9% for products liability and 17% for property lines. Gross premiums written decreased 9% for professional liability lines and 11% for commercial automobile.
 
    Regional gross premiums increased by 2% to $737 million in 2006 from $724 million in 2005. The number of new and renewal policies issued in 2006, net of policy cancellations, decreased 3%. Average prices for renewal policies, adjusted for changes in exposure, decreased 2%. Gross premiums written increased 6% for workers’ compensation and 1% for commercial automobile. Gross premiums include assigned risk premiums of $64 million in 2006 and $67 million in 2005.
 
    Alternative markets gross premiums decreased by 7% to $397 million in 2006 from $427 million in 2005. Gross premiums included gross premiums for assigned risk plans of $39 million in 2006 and $57 million in 2005. Excluding the assigned risk plan premiums, alternative market’s gross premiums decreased by 3%. The number of new and renewal policies issued in 2006, net of policy cancellations, decreased 1%. Average prices for renewal policies, adjusted for changes in exposure, decreased 4%. Gross premiums written decreased 16% for primary workers’ compensation and increased 8% for excess workers’ compensation. The decline in premiums for primary workers’ compensation was primarily due to rate decreases in California.
 
    Reinsurance gross premiums increased by 28% to $506 million in 2006 from $395 million in 2005. Average prices for renewal business increased 2%. Casualty gross premiums written increased 33% to $419 million, and property gross premiums written increased 10% to $87 million. The 2006 premiums include $91 million related to two new medical malpractice reinsurance agreements. While these agreements contain limits on the potential amount of losses to be paid by the Company they also contain limits on the potential amount of profit to be earned by the Company.

    International gross premiums increased by 28% to $116 million in 2006 from $91 million in 2005 due to growth in Europe and Argentina.
     Net Premiums Earned. Net premiums earned increased 9% to $2.3 billion from $2.1 billion in 2005. Insurance premiums are earned ratably over the policy term, and therefore premiums earned in 2006 are related to premiums written during both 2006 and 2005. The 9% growth rate for 2006 earned premiums reflects the underlying growth in net premiums written in those years.
     Net Investment Income. Following is a summary of net investment income for the six months ended June 30, 2006 and 2005 (dollars in thousands):

     Net investment income increased 51% to $277 million in 2006 from $183 million in 2005. Average invested assets (including cash and cash equivalents) increased 24% to $10.6 billion in 2006 from $8.6 billion in 2005 as a result of cash flow from operations and financing activities during the past eighteen months. The average annualized gross yield on investments increased to 5.2% in 2006 from 4.3% in 2005 due to higher short-term interest rates and higher returns on the arbitrage trading account.
     Service Fees. The alternative markets segment offers fee-based services to help clients develop and administer self-insurance programs, primarily for workers’ compensation coverage. Service fees were $54 million in 2006, down from $59 million in 2005, primarily as a result of a decline in fees for managing assigned risk plans.
     Realized Investment Gains (Losses). Realized investment gains (losses) result primarily from sales of securities, as well as from provisions for other than temporary impairment in securities. Realized investment gains were $2 million in 2006 compared with $6 million in 2005. The Company buys and sells securities on a regular basis in order to maximize the 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.
     Losses and Loss Expenses. Losses and loss expenses increased 10% to $1.4 billion in 2006 from $1.3 billion in 2005 due to increased premium volume. The consolidated loss ratio was 61.9% in 2006 compared with 61.8% in 2005. The 2006 loss ratio reflects an increase in the expected loss ratio for accident year 2006, offset by a decrease in prior year adverse reserve development ($14 million in 2006 compared with $70 million in 2005). A summary of loss ratios in 2006 compared with 2005 by business segment follows:
    Specialty’s loss ratio decreased to 60.3% in 2006 from 62.0% in 2005 principally due to lower prior year adverse reserve development.
 
    The regional loss ratio increased to 59.4% in 2006 from 55.4% in 2005. The 2006 loss ratio reflects an increase in the expected loss ratio for accident year 2006 as well as higher property losses during the period. Weather-related losses were $25 million in 2006 compared with $15 million in 2005.

Table of Contents

    Alternative market’s loss ratio decreased to 53.6% from 64.3% primarily as a result of the favorable reserve development related to workers’ compensation business in California.
 
    The reinsurance loss ratio increased to 73.6% in 2006 from 68.1% in 2005. The increase reflects the impact of higher loss ratios for the new medical malpractice reinsurance agreements referred to above, partially offset by lower prior year adverse reserve development.
 
    The international loss ratio decreased to 64.0% in 2006 from 64.6% in 2005 primarily as a result of lower losses for business written in Europe.
     Other Operating Costs and Expenses. Following is a summary of other operating costs and expenses for the six months ended June 30, 2006 and 2005 (dollars in thousands):
                 
    2006     2005  
Underwriting expenses
  $ 623,933     $ 583,289  
Service expenses
    45,002       47,754

Total
  $ 714,580     $ 661,405  
 
           
     Underwriting expenses increased 7% primarily as a result of higher premium volume. Underwriting expenses are primarily comprised of commissions paid to agents and brokers, premium taxes and other assessments and internal underwriting costs. The consolidated expense ratio (underwriting expenses expressed as a percentage of premiums earned) decreased to 26.7% in 2006 from 27.4% in 2005. The decrease is primarily due to the impact of lower expense ratios for the new medical malpractice reinsurance agreements referred to above.
     Service expenses, which represent the costs associated with the alternative market’s fee-based business, decreased 6% to $45 million primarily as a result of a decrease in costs associated with the servicing of assigned risk plan business.
     Other costs and expenses, which represent primarily general and administrative expenses for the parent company, increased 50% to $46 million primarily as a result of higher incentive compensation costs.
     Interest Expense. Interest expense increased 25% to $47 million as a result of interest expense related to $200 million of 5.6% senior notes issued in May 2005 and $250 million of 6.75% junior subordinated debentures issued in July 2005. This was partially offset by a reduction in interest expense as a result of the repayment of $100 million 6.25% senior notes in January 2006.
     Income taxes. The effective income tax rate was 29% in 2006 and 30% in 2005. The effective tax rate differs from the federal income tax rate of 35% primarily because of tax-exempt investment income.

     The following table presents the Company’s net income and net income per share for the three months ended June 30, 2006 and 2005 (amounts in thousands, except per share data):
                 
    2006   2005
 
Net income
  $ 165,452     $ 134,079  
Weighted average diluted shares
    202,450       200,051  
Net income per diluted share
  $ .82     $ .67  
 
     The increase in net income in 2006 compared with 2005 reflects higher investment income and higher profits from underwriting activity. The increase in investment income was the result of an increase in average invested assets as well as an increase in the average yield on investments. The improvement in underwriting results is attributable to a 9% increase in premiums earned and a 0.9 percentage point decrease in the expense ratio (underwriting expenses experienced as a percentage of premiums earned). These were partially offset by a 0.6 percentage point increase in the loss ratio (losses and loss expenses incurred expressed as percentage of premiums earned).
     Gross Premiums Written. Gross premiums written were $1.3 billion in 2006, up 7% from 2005. While prices increased significantly in 2002 and 2003, the Company experienced an increased level of price competition in 2004 and 2005. This trend continued in 2006 with price levels for renewal business declining approximately 2%, as compared with the prior year period.
     Gross premiums for the regional and alternative markets segments include premiums written on behalf of assigned risk plans managed by the Company. The assigned risk premiums are fully reinsured by the respective state-sponsored assigned risk plans.
     A summary of gross premiums written in 2006 compared with 2005 by business segment follows:
    Specialty gross premiums increased 2% to $522 million in 2006 from $513 million in 2005. The number of specialty policies issued in 2006 decreased 1%. Average prices for renewal policies, adjusted for changes in exposure, decreased 1%. Gross premiums written increased 8% for premises operations, 15% for products liability and 16% for property lines. Gross premiums written decreased 13% for professional liability lines and 17% for commercial automobile.
 
    Regional gross premiums increased by 4% to $372 million in 2006 from $356 million in 2005. The number of policies issued in 2006 was unchanged. Average prices for renewal policies, adjusted for changes in exposure, decreased 3%. Gross premiums written increased 4% for workers’ compensation, 4% for commercial multiple peril and 6% for commercial automobile. Gross premiums include assigned risk premiums of $31 million in 2006 and $32 million in 2005.
 
    Alternative markets gross premiums decreased by 14% to $124 million in 2006 from $144 million in 2005. Gross premiums included gross premiums for assigned risk plans of $16 million in 2006 and $20 million in 2005. Excluding the assigned risk plan premiums, alternative market’s gross premiums decreased by 13%. The number of policies issued in 2006 decreased 2%. Average prices for renewal policies, adjusted for changes in exposure, decreased 9%. Gross premiums written decreased 21% for primary workers’ compensation and increased 2% for excess workers’ compensation. The decline in premiums for primary workers’ compensation was primarily due to rate decreases in California.
 
    Reinsurance gross premiums increased 35% to $259 million in 2006 from $192 million in 2005. Average prices for renewal business increased 3%. Casualty gross premiums written increased 40% to $217 million, and property gross premiums written increased 11% to $42 million. The 2006 premiums include $42 million related to the new medical malpractice reinsurance agreements referred to above.

    International gross premiums increased by 46% to $65 million in 2006 from $44 million in 2005 due to growth in Europe and Argentina.
     Net Premiums Earned. Net premiums earned increased 9% to $1.2 billion from $1.1 billion in 2005. Insurance premiums are earned ratably over the policy term, and therefore premiums earned in 2006 are related to premiums written during both 2006 and 2005. The 9% growth rate for 2006 earned premiums reflects the underlying growth in net premiums written in those years.
     Net Investment Income. Following is a summary of net investment income for the three months ended June 30, 2006 and 2005 (dollars in thousands):
                                 
                    Average Annualized

Total
  $ 145,067     $ 93,622                  
 
                           
     Net investment income increased 55% to $145 million in 2006 from $94 million in 2005. Average invested assets (including cash and cash equivalents) increased 22% to $10.8 billion in 2006 from $8.8 billion in 2005 as a result of cash flow from operations and financing activity over the last fifteen months. The average annualized gross yield on investments increased to 5.4% in 2006 from 4.3% in 2005 due primarily to higher short-term interest rates and higher returns on the arbitrage trading account.
     Service Fees. The alternative markets segment offers fee-based services to help clients develop and administer self-insurance programs, primarily for workers’ compensation coverage. Service fees decreased to $27 million in 2006 from $29 million in 2005 primarily as a result of a decline in fees for managing assigned risk plans.
     Realized Investment Gains (Losses). Realized investment gains (losses) result primarily from sales of securities, as well as from provisions for other than temporary impairment in securities. Realized investment losses were $0.7 million in 2006 compared with realized investment gains of $6 million in 2005. The Company buys and sells securities on a regular basis in order to maximize the 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.
     Losses and Loss Expenses. Losses and loss expenses increased 10% to $742 million in 2006 from $675 million in 2005 due to increased premium volume. The consolidated loss ratio increased to 62.5% in 2006 from 61.9% in 2005. The 2006 loss ratio reflects an increase in the expected loss ratio for accident year 2006, partially offset by a decrease in prior year adverse reserve development ($7 million in 2006 compared with $42 million in 2005). A summary of loss ratios in 2006 compared with 2005 by business segment follows:
    Specialty’s loss ratio decreased to 60.7% in 2006 from 62.6% in 2005 principally due to lower prior year adverse reserve development.

24


Table of Contents

    The regional loss ratio increased to 62.0% in 2006 from 57.6% in 2005. The 2006 loss ratio reflects an increase in the expected loss ratio for accident year 2006 as well as higher property losses during the period. Weather-related losses were $20 million in 2006 compared with $12 million in 2005.
 
    Alternative market’s loss ratio decreased to 51.8% from 60.7% primarily as a result of favorable reserve development related to workers’ compensation business in California.
 
    The reinsurance loss ratio increased to 74.5% in 2006 from 67.2% in 2005. The increase reflects the impact of higher loss ratios for the new medical malpractice reinsurance agreements referred to above, partially offset by lower prior year adverse reserve development.
 
    The international loss ratio decreased to 62.4% in 2006 from 64.0% in 2005 primarily as a result of lower losses for business written in Europe.
     Other Operating Costs and Expenses. Following is a summary of other operating costs and expenses for the three months ended June 30, 2006 and 2005 (dollars in thousands):
                 
    2006     2005  
Underwriting expenses
  $ 313,843     $ 297,538  
Service expenses
    21,817       23,527  
Other costs and expenses
    23,266       13,535  
 
           
Total
  $ 358,926     $ 334,600  
 
           
     Underwriting expenses increased 5% in 2006 compared with 2005 primarily as a result of higher premium volume. Underwriting expenses are primarily comprised of commissions paid to agents and brokers, premium taxes and other assessments and internal underwriting costs. The consolidated expense ratio (underwriting expenses expressed as a percentage of premiums earned) decreased to 26.4% in 2006 from 27.3% in 2005. The decrease is primarily due to the impact of lower expense ratios for the new medical malpractice reinsurance agreements referred to above.
     Service expenses, which represent the costs associated with the alternative market’s fee-based business, decreased 7% to $22 million primarily as a result of a decrease in costs associated with the servicing of assigned risk plan business.
     Other costs and expenses, which represent primarily general and administrative expenses for the parent company, increased 72% to $23 million primarily as a result of higher incentive compensation costs.
     Interest Expense. Interest expense increased 21% to $23 million as a result of interest expense related to $200 million of 5.6% senior notes issued in May 2005 and $250 million of 6.75% junior subordinated debentures issued in July 2005. This was partially offset by a reduction of interest expense as a result of the repayment of $100 million 6.25% senior notes in January 2006.
     Income taxes. The effective income tax rate was 29% in 2006 and 2005. The effective tax rate differs from the federal income tax rate of 35% primarily because of tax-exempt investment income.

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 adequate to meet payment obligations. 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 carrying value of the Company’s investment portfolio and investment-related assets as of June 30, 2006 and December 31, 2005 were as follows (dollars in thousands):
                 
    June 30,     December 31,

     Fixed Maturities. 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, active 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. At June 30, 2006 (as compared to December 31, 2005), the fixed maturities portfolio mix was as follows: U.S. Government securities were 16% (15% in 2005); state and municipal securities were 53% (55% in 2005); corporate securities were 9% (9% in 2005); mortgage-backed securities were 18% (18% in 2005); and foreign bonds were 4% (3% in 2005).
     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 market 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.
     Equity Securities Available for Sale. Equity securities available for sale primarily represent investments in common and preferred stocks of publicly traded real estate investment trusts, banks and utilities.

26


Table of Contents

     Equity Securities Trading Account. The trading account is comprised of direct investments in arbitrage securities and investments in arbitrage-related limited partnerships that specialize in merger arbitrage and convertible arbitrage strategies. Merger arbitrage is the business of investing in the securities of publicly held companies that are the targets in announced tender offers and mergers. Convertible arbitrage is the business of investing in convertible securities with the goal of capitalizing on price differentials between these securities and their underlying equities.
     Investments in Partnerships and Affiliates. At June 30, 2006 (as compared to December 31, 2005), investments in partnerships and affiliates were as follows: equity in Kiln plc was $81 million ($74 million in 2005); real estate funds were $253 million ($160 million in 2005); fixed income relative value funds were $12 million ($52 million in 2005); and other investments were $39 million ($36 million in 2005).
     Securities in an Unrealized Loss Position. The following table summarizes all securities in an unrealized loss position at June 30, 2006 and December 31, 2005 by the length of time those securities have been continuously in an unrealized loss position:

Table of Contents

     At June 30, 2006, gross unrealized gains were $130 million, or 1% of total investments, and gross unrealized losses were $157 million, or 1% of total investments. There were 401 securities that have been continuously in an unrealized loss position for more than six months. Those securities had an aggregate fair value of $4.1 billion and an aggregate unrealized loss of $119 million. The decline in market value for these securities is primarily due to an increase in market interest rates. Management regularly reviews its investment portfolio to determine whether a decline in value as a result of deterioration in the financial position or future prospects of the issuer is considered to be other than temporary. A decline is value is considered to be other than temporary where there has been a sustained reduction in market value and there are no mitigating circumstances. If a decline in value is considered other than temporary, the Company reduces the carrying value of the security and reports a realized loss on its statement of income.
Liquidity and Capital Resources
     Cash Flow. Cash flow provided from operating activities was $562 million in 2006 and $742 million in 2005. The decrease is primarily a result of higher cash transfers to the arbitrage trading account ($225 million in 2006 compared with $75 million in 2005).
     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 85% invested in cash, cash equivalents and marketable fixed income securities as of June 30, 2006. If the sale of fixed income 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.
     Financing Activity. At June 30, 2006, the Company had senior notes, junior subordinated debentures and other debt outstanding with a carrying value of $1,320 million and a face amount of $1,337 million. The maturities of the outstanding debt are $89 million in 2008, $150 million in 2010, $200 million in 2013, $200 million in 2015, $150 million in 2019, $76 million in 2022, $12 million in 2023 and $460 million in 2045 (of which $210 million is prepayable in 2006 and $250 million is prepayable in 2010). The Company repaid $100 million of 6.25% senior notes in January 2006.
     As of June 30, 2006, the Company has repurchased preferred securities of the W. R. Berkley Capital Trust with an aggregate principal amount of $84 million and a carrying value of $83 million. The preferred securities, which are secured by the Company’s junior subordinated debentures, are reported as investments in fixed income securities on the accompanying balance sheet and have not been deducted from the outstanding debt amounts referred to in the preceding paragraph.
     At June 30, 2006, stockholders’ equity was $2.8 billion and total capitalization (stockholders’ equity, senior notes, junior subordinated debentures and other debt) was $4.1 billion. The percentage of the Company’s capital attributable to senior notes and other debt and junior subordinated debentures was 32% at June 30, 2006, compared with 36% at December 31, 2005.

Item 3. Quantitative and Qualitative Disclosure About Market Risk
     The Company’s market risk generally represents the risk of loss that may result from the potential change in the fair value of the Company’s investment portfolio as a result of fluctuations in prices, interest rates and currency exchange rates. The Company attempts to manage its interest rate risk by maintaining an appropriate relationship between the average duration of its investment portfolio and the approximate duration of its liabilities, i.e., policy claims and debt obligations.
     The duration of the investment portfolio increased to 3.9 years at June 30, 2006 from 3.8 years at December 31, 2005. The overall market risk relating to the Company’s portfolio has remained similar to the risk at December 31, 2005.
Item 4. Controls and Procedures
     Disclosure Controls and Procedures. The Company’s management, including its Chief Executive Officer and Chief Financial Officer, has conducted an evaluation of the effectiveness of the Company’s disclosure controls and procedures pursuant to Securities Exchange Act Rule 13a-14 as of the end of the period covered by this quarterly report.
