NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

(1) General

The unaudited consolidated financial statements, which include the accounts of W. R. Berkley Corporation and its subsidiaries (the “Company”), have been prepared on the basis of 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. Reclassifications have been made in the 2022 financial statements as originally reported to conform to the presentation of the 2023 financial statements. For the ~~quarter~~for nine months ended ~~March 31,~~September 30, 2022, the Company did not correct the proceeds from sale of fixed maturity securities and purchase of fixed maturity securities lines within the consolidated statements of cash flows for an incremental inter-company elimination as the effects were not material and had no impact on the total amount of investing activities.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the revenues and expenses reflected during the reporting period. For further information related to 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, 2022.

The income tax provision has been computed based on the Company’s estimated annual effective tax rate. The effective income tax rate differs from the federal income tax rate of 21% primarily due to ~~state~~tax benefits related to equity-based compensation and ~~foreign~~tax-exempt investment income, ~~taxes,~~ which was partially offset by ~~tax-exempt investment income.~~state income taxes.

(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 (including 11,416,856 and 11,592,699 common shares held in a grantor trust as of ~~March 31,~~September 30, 2023 and 2022, respectively). The common shares held in the grantor trust are for delivery upon settlement of vested but mandatorily deferred restricted stock units ("RSUs"). Shares held by the grantor trust do not affect diluted shares outstanding since the shares deliverable under vested RSUs were already included in diluted shares outstanding. Diluted EPS is based upon the weighted average number of basic 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:

During the nine months ended September 30, 2023, the Company increased the allowance for expected credit losses for available for sale securities in part due to changes in economic assumptions utilized in its credit loss model, primarily affecting the financial services and real estate sectors, and an increase in unrealized loss related to the foreign government portfolio. During the nine months ended September 30, 2022, the Company increased the allowance for expected credit losses for available for sale securities mainly due to an increase in unrealized losses primarily associated with foreign government securities.

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 uses put options and call options in order to mitigate the impact of potential changes in market conditions on the merger arbitrage trading account. These options are reported at fair value. As of ~~March 31,~~September 30, 2023, the fair value of long option contracts outstanding was $5$256 thousand (notional amount of $2$50 million) and the fair value of short option contracts was $6 million (notional amount of $50 million). Other than with respect to the use of these trading account securities, the Company does not make use of derivatives.

(10) Investment Funds

The Company evaluates whether it is an investor in a variable interest entity ("VIE"). Such entities do not have sufficient equity at risk to finance their activities without additional subordinated financial support, or the equity investors, as a group, do not have the characteristics of a controlling financial interest (primary beneficiary). The Company determines whether it is the primary beneficiary of an entity subject to consolidation based on a qualitative assessment of the VIE's capital structure, contractual terms, nature of the VIE's operations and purpose, and the Company's relative exposure to the related risks of the VIE on the date it becomes initially involved in the VIE and on an ongoing basis. The Company is not the primary beneficiary in any of its investment funds, and accordingly, carries its interests in investment funds under the equity method of accounting.

The Company’s maximum exposure to loss with respect to these investments is limited to the carrying amount reported on the Company’s consolidated balance sheet and its unfunded commitments, which were ~~$408~~$353 million as of ~~March 31,~~September 30, 2023.

Substantially all of the securities in an unrealized loss position are rated investment grade, except for the securities in the foreign government classification. A significant amount of the unrealized loss on foreign government securities is the result of changes in currency exchange rates.

A summary of the Company’s non-investment grade fixed maturity securities that were in an unrealized loss position at ~~March 31,~~September 30, 2023 is presented in the table below:


($ in thousands)	($ in thousands)	Number of Securities	Aggregate Fair Value		Gross Unrealized Loss		($ in thousands)	Number of Securities	Aggregate Fair Value		Gross Unrealized Loss

For fixed maturity securities that management does not intend to sell or to be required to sell, the portion of the decline in value that is considered to be due to credit factors is recognized in earnings, and the portion of the decline in value that is considered to be due to non-credit factors is recognized in other comprehensive income (loss).

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.

(15) Fair Value Measurements

The Company’s fixed maturity available for sale securities, equity securities and its arbitrage 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.

(16) Reserves for Loss and Loss Expenses

The Company's reserves for losses and loss expenses are comprised of case reserves and incurred but not reported liabilities ("IBNR"). When a claim is reported, a case reserve is established for the estimated ultimate payment based upon known information about the claim. As more information about the claim becomes available over time, case reserves are adjusted up or down as appropriate. Reserves are also established on an aggregate basis to provide for IBNR liabilities and expected loss reserve development on reported claims.

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. 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” 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 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 priced and 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.

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 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.

(1) Claims occurring during the current year are net of loss reserve discounts of ~~$11~~$35 million and $7$26 million for the ~~three~~nine months ended ~~March 31,~~September 30, 2023 and 2022, respectively.

(2) The change in estimates for claims occurring in prior years is net of loss reserve discount. On an undiscounted basis, the estimates for claims occurring in prior years decreased by $12 million and increased by ~~$19 million and decreased by $4~~$20 million for the ~~three~~nine months ended ~~March 31,~~September 30, 2023 and 2022, respectively.

(3) For certain retrospectively rated insurance policies and reinsurance agreements, reserve development is offset by additional or return premiums. Adverse development, net of additional and return premiums, was ~~$24~~$20 million and $37 million for the ~~three~~nine months ended ~~March 31,~~September 30, 2023 and ~~favorable development was $1 million for the three months ended March 31,~~ 2022, respectively.

The COVID-19 global pandemic ~~has~~ impacted, and may further impact, the Company’s results through its effect on claim frequency and severity. Loss cost trends have been impacted and may be further impacted by COVID-19-related claims in certain lines of business. Losses incurred from COVID-19-related claims have been offset, to a certain extent, by lower claim frequency in certain lines of our businesses; however, asloss costs. Accordingly, the ~~economy and legal systems have reopened, the benefit of lower claim frequency has partially abated. The~~ ultimate net impact of COVID-19 on the ~~Company~~Company’s reserves remains uncertain. New variants of the COVID-19 virus continue to create risks with respect to loss costs and the potential for renewed impact of the other effects of COVID-19 associated with economic conditions, inflation, and social distancing and work from home rules.

Most of the COVID-19-related claims reported to the Company to date involve certain short-tailed lines of business, including contingency and event cancellation, business interruption, and film production delay. The Company has also received COVID-19-related claims for longer-tailed casualty lines of business such as workers’ compensation and other liability; however, the estimated incurred loss impact for these reported claims are not material at this time. Given the continuing uncertainty regarding the pandemic's pervasiveness, the future impact that the pandemic may have on claim frequency and severity remains uncertain at this time.

The Company has estimated the potential COVID-19 impact to its contingency and event cancellation, workers’ compensation, and other lines of business under a number of possible scenarios; however, due to COVID-19’s continued evolving impact, there remains uncertainty around the Company’s COVID-19 reserves. In addition, should the pandemic continue or worsen as a result of new COVID-19 variants or otherwise, governments in the jurisdictions where we operate may impose restrictions, including lockdowns, as well as renew their efforts to expand policy coverage terms beyond the policy’s intended coverage. Accordingly, losses arising from these actions, and the other factors described above, could exceed the Company’s reserves established for those related policies.

As of ~~March 31,~~September 30, 2023, the Company had recognized losses for COVID-19-related claims activity, net of reinsurance, of approximately ~~$344~~$354 million, of which ~~$291~~$299 million relates to the Insurance segment and ~~$53~~$55 million relates to the Reinsurance & Monoline Excess segment. Such ~~$344~~$354 million of COVID-19-related losses ~~included $339 million of~~are considered reported ~~losses and $5 million of IBNR.~~losses. For the ~~three~~nine months ended ~~March 31,~~September 30, 2023, the Company recognized current accident year losses for COVID-19-related claims activity, net of reinsurance, of approximately ~~$43~~$670 thousand, all of which relates to the Insurance segment.

During the ~~three~~nine months ended ~~March 31,~~September 30, 2023, adverse prior year development (net of additional and return premiums) of ~~$24~~$20 million included ~~$17~~$26 million of adverse development for the Insurance segment, ~~and $7~~partially offset by $6 million of favorable development for the Reinsurance & Monoline Excess segment.

Such adverse development during the nine months ended September 30, 2023 was concentrated in the first quarter, with $24 million of adverse development (net of additional and return premiums) in the first quarter, partially offset by favorable development of $4 million in the second and third quarters. This overall adverse development ~~for~~during the first quarter in both business segments was ~~primarily attributed~~due to property catastrophe losses related to 2022 events which were still being adjusted and ~~settled during the first quarter of 2023.~~settled. In particular, losses related to U.S. winter storms which occurred during the month of December were a significant driver of the development, as information gathering and evaluation of many of these losses ~~were~~was still ongoing into the new year.

InFor the Insurance segment, in addition to the property prior year adverse development discussed above, the adverse development during the ~~first quarter of~~nine months ended September 30, 2023 ~~the Insurance segment experienced~~included adverse prior year development on casualty lines for the 2016 through 2019 accident years, which was largely offset by favorable prior year development on casualty lines for the 2020 through 2022 accident ~~year.~~years. The adverse development on the 2016 through 2019 accident years was concentrated in the ~~other~~general liability line of business, and to a lesser degree professional liability, including medical ~~professional.~~professional, and commercial auto liability. The development, which particularly impacted business attaching excess of primary policy limits, was driven by a larger than expected number of large losses reported. The Company believes social inflation is contributing to an increase in the frequency of large losses for these accident years. Social inflation can include higher settlement demands from plaintiffs, use of tactics such as litigation funding by the plaintiffs’ bar, negative public sentiment towards large businesses and corporations, and erosion of tort reforms, among others.

The favorable prior year development on casualty lines for the 2020 through 2022 accident ~~year~~years in the Insurance segment was concentrated in the ~~other liability,~~ professional liability, ~~and~~ workers’ compensation, and general liability lines of business. Due to uncertainty regarding incurred loss frequency and severity in light of ongoing social inflation and the ~~emergence from~~impacts of the COVID-19 pandemic, the Company set its initial loss ratios for the 2020 through 2022 accident ~~year~~years prudently, and largely maintained these estimates through the end of ~~2022.~~each respective accident year. The reported loss experience to date for these lines of business for the 2020 through 2022 accident ~~year~~years has been significantly better than was expected, and the Company has begun to react to this favorable emergence as the accident years mature beyond the age of 12 months. However, commercial auto liability experienced adverse prior year development for the 2020 through 2022 accident years, partially offsetting the favorable development discussed above, which was driven by a larger than expected number of large losses reported.

For the Reinsurance & Monoline Excess segment, the favorable development during the nine months ended September 30, 2023 was driven mainly by favorable development in ~~the first quarter~~excess workers’ compensation, partially offset by adverse development in property (discussed above) and non-proportional reinsurance assumed liability lines of ~~2023 for these lines.~~business. The favorable excess workers’ compensation development was driven by continued lower claim frequency and reported losses relative to our expectations, and to favorable claim settlements. The favorable development was spread across many prior accident years. The adverse development on reinsurance assumed liability was associated primarily with our U.S. assumed reinsurance business, and related to accounts reinsuring excess and umbrella business and construction projects. The adverse development was concentrated mainly in accident years 2017 through 2020.

During the ~~three~~nine months ended ~~March 31,~~September 30, 2022, ~~favorable~~adverse prior year development (net of additional and return premiums) of $1$37 million included $6$33 million ~~of favorable development~~ for the Insurance segment ~~largely offset by $5~~and $4 million ~~of adverse development~~ for the Reinsurance & Monoline Excess segment.

The ~~overall favorable~~adverse development for the Insurance segment ~~was~~primarily related to COVID-19 losses at two businesses. These businesses wrote policies providing coverage for event cancellation and film production delay which were heavily impacted by losses directly caused by the COVID-19 pandemic. Most of this COVID-19-related adverse development emerged during the third quarter as a result of settlements of claims at values higher than our expectations.

The adverse development mentioned above includes favorable prior year development for the Insurance segment primarily attributable to ~~favorable development on~~ the 2020 and 2021 accident ~~year, largely offset by~~years and adverse development on the 2015 through 2019 accident years. The favorable development on the 2020 and 2021 accident ~~year~~years was concentrated in the ~~commercial auto liability,~~ other liability ~~and accident and health (employer stop loss)~~ lines of ~~business.~~business, including professional liability, products liability, commercial multi-peril liability and workers’ compensation.

In the ordinary course of business, the Company is subject to disputes, litigation and arbitration arising from its insurance and reinsurance businesses. These matters are generally related to insurance and reinsurance claims and are considered in the establishment of loss and loss expense reserves. In addition, the Company may also become involved in legal actions which seek extra-contractual damages, punitive damages or penalties, including claims alleging bad faith in handling of insurance claims.

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) Leases

Lessees are required to recognize a right-of-use asset and a lease liability for leases with terms of more than 12 months on the balance sheet. All leases disclosed within this footnote are classified as operating leases. Recognized right-of-use asset and lease liability are reported within other assets and other liabilities, respectively, in the consolidated balance sheet. Lease expense is reported in other operating costs and expenses in the consolidated statement of income and accounted for on a straight-line basis over the lease term.

To determine the discount rate used to calculate present value of future minimum lease payments, the Company uses its incremental borrowing rate during the lease commencement period in line with the respective lease duration. In certain cases, the Company has the option to renew the lease. Lease renewal future payments are included in the present value of the future minimum lease payments when the Company determines it is reasonably certain to renew.

The main leases entered into by the Company are for office space used by the Company’s operating units across the world. Additionally, the Company, to a lesser extent, has equipment leases mainly for office equipment.

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 worldwide in two segments of the property and casualty business: Insurance and Reinsurance & Monoline Excess. 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. Over the years, the Company has formed numerous operating units that are focused on important parts of the economy in the U.S., including healthcare, cyber security, energy and agriculture, and on growing international markets, including the Asia-Pacific region, South America and Mexico.

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 capital employed in the industry, and the industry’s willingness to deploy that capital.

The Company’s profitability is also affected by its investment income and investment gains. The Company’s invested assets 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.

The Company also invests in equity securities, merger arbitrage securities, investment funds, private equity, loans and real ~~estate related~~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's share of the earnings or losses from investment funds is generally reported on a one-quarter lag in order to facilitate the timely completion of the Company's consolidated financial statements.

In June 2023, the Company completed a sale of the property and casualty insurance services division of Breckenridge IS, Inc. and recognized a pre-tax net realized gain on investment of $88 million.

On March 7, 2022, the Company sold a real estate investment consisting of an office building located in London for £718 million. The Company realized a ~~pretax~~pre-tax gain of $317 million in the first quarter of 2022, before transaction expenses and the impact of foreign currency, including the reversal of the currency translation adjustment. The gain was $251 million after such adjustments.

The COVID-19 pandemic, including the related impact on the U.S. and global economies, continued to affect our results of operations. At the same time, COVID-19 has led to reduced loss frequency in certain lines of business (which partially returned to pre-pandemic levels as many economies and legal systems have reopened). The ultimate impact of COVID-19 on the economy and the Company’s results of operations, financial position and liquidity is not within the Company’s control and remains unclear due to, among other factors, its ongoing impact and uncertainty in connection with its claims, reserves and reinsurance recoverables.

Critical Accounting Estimates

The following presents a discussion of accounting policies and estimates relating to reserves for losses and loss expenses, assumed premiums and allowance for expected credit losses on 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

2831

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 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 uncertainty. 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.

2932

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.

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 the latest reported loss data, 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 2022:


(In thousands)	Frequency (+/-)
Severity (+/-)	1%		5%		10%
1%	$	116,072	$	349,370	$	640,993
5%	349,370		591,908		895,081
10%	640,993		895,081		1,212,690

Our net reserves for losses and loss expenses of approximately ~~$14.6~~$15.3 billion as of ~~March 31,~~September 30, 2023 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. The impact of such changes would likely be manifested gradually over the course of many years, as the magnitude of the changes became evident.

Approximately ~~$3.0~~$3.1 billion, or ~~21%~~20%, of the Company’s net loss reserves as of ~~March 31,~~September 30, 2023 relate to the Reinsurance & Monoline Excess segment. There is a higher degree of uncertainty and greater variability regarding estimates of excess workers' compensation and assumed reinsurance loss reserves. In the case of excess workers’ compensation, our policies generally attach at $1 million or higher. The claims which reach our layer therefore tend to involve the most serious injuries and many remain open for the lifetime of the claimant, which extends the claim settlement tail. These claims also occur less frequently but tend to be larger than primary claims, which increases claim variability. In the case of assumed reinsurance our loss reserve 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 also extended. Management considers the impact of delayed reporting and the extended tail in its selection of loss development factors for these lines of business.

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

3033

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 & Monoline Excess are net of an aggregate net discount of ~~$411~~$390 million and $416 million as of ~~March 31,~~September 30, 2023 and December 31, 2022, respectively.

(2) Short-tail lines include commercial multi-peril (non-liability), inland marine, accident and health, fidelity and surety, boiler and machinery and other lines.

(3) Reinsurance & Monoline Excess includes property and casualty reinsurance, as well as operations that solely retain risk on an excess basis.

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 ~~three~~nine months ended ~~March 31,~~September 30, 2023 and 2022 are as follows:


(In thousands)	(In thousands)	2023		2022		(In thousands)	2023		2022
Increase in prior year loss reserves	Increase in prior year loss reserves	$	(28,205)	$	(3,761)	Increase in prior year loss reserves	$	(27,186)	$	(54,632)

significantly better than was expected, and the Company has begun to react to this favorable emergence as the accident years mature beyond the age of 12 months. However, commercial auto liability experienced adverse prior year development for the 2020 through 2022 accident years, partially offsetting the favorable development discussed above, which was driven by a larger than expected number of large losses reported.

Reserve Discount. The Company discounts its liabilities for certain workers’ compensation reserves. The amount of workers’ compensation reserves that were discounted was ~~$1,448~~$1,356 million and $1,464 million at ~~March 31,~~September 30, 2023 and December 31, 2022, respectively. The aggregate net discount for those reserves, after reflecting the effects of ceded reinsurance, was ~~$411~~$390 million and $416 million at ~~March 31,~~September 30, 2023 and December 31, 2022, respectively. At ~~March 31,~~September 30, 2023, discount rates by year ranged from 0.7% to 6.5%, with a weighted average discount rate of 3.4%.

Substantially all of the workers’ compensation discount (97% of total discounted reserves at ~~March 31,~~September 30, 2023) relates to 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 3% of total discounted reserves at ~~March 31,~~September 30, 2023), 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 ~~$61~~$58 million at ~~March 31,~~September 30, 2023 and $60 million at December 31, 2022. 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.

Allowance for Expected Credit Losses on Investments.

Fixed Maturity Securities – For fixed maturity securities in an unrealized loss position where the Company intends to sell, or it is more likely than not that it will be required to sell the security before recovery in value, the amortized cost basis is written down to fair value through net investment gains (losses). For fixed maturity securities in an unrealized loss position where the Company does not intend to sell, or it is more likely than not that it will not be required to sell the security before recovery in value, the Company evaluates whether the decline in fair value has resulted from credit losses or all other factors (non-credit factors). In making this assessment, the Company considers the extent to which fair value is less than amortized cost, changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, an allowance for expected credit losses is recorded for the credit loss through net investment gains (losses), limited by the amount that the fair value is less than the amortized cost basis. The allowance is adjusted for any change in expected credit losses and subsequent recoveries through net investment gains (losses). The impairment related to non-credit factors is recognized in other comprehensive income (loss).

The Company’s credit assessment of allowance for expected credit losses uses a third party model for available for sale and held to maturity securities, as well as loans receivable. The allowance for expected credit losses is generally based on the performance of the underlying collateral under various economic and default scenarios that 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, the ability of the issuer to make scheduled payments, historical performance and other relevant economic and performance factors. A discounted cash flow analysis is used to ascertain the amount of the allowance for expected credit losses, if any. In general, the model reverts to the rating-level long-term average marginal default rates based on 10 years of historical data, beyond the forecast period. For other inputs, the model in most cases reverts to the baseline long-term assumptions linearly over 5 years beyond the forecast period. The long-term assumptions are based on the historical averages.

The Company classifies its fixed maturity securities by credit rating, primarily based on ratings assigned by credit rating agencies. For purposes of classifying securities with different ratings, the Company uses the average of the credit ratings assigned, unless in limited situations the Company’s own analysis indicates an internal 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.

A summary of the Company’s non-investment grade fixed maturity securities that were in an unrealized loss position at ~~March 31,~~September 30, 2023 is presented in the table below:


($ in thousands)	($ in thousands)	Number of Securities	Aggregate Fair Value		Gross Unrealized Loss		($ in thousands)	Number of Securities	Aggregate Fair Value		Gross Unrealized Loss

Total	Total	65	$	167,130	$	71,448	Total	95	$	151,750	$	101,686

As of ~~March 31,~~September 30, 2023, the Company has recorded an allowance for expected credit losses on fixed maturity securities of ~~$37~~$46 million. The Company has evaluated the remaining 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.

Loans Receivable – For loans receivable, the Company estimates an allowance for expected credit losses based on relevant information about past events, including historical loss experience, current conditions and forecasts that affect the expected collectability of the amortized cost of the financial asset. The allowance for expected credit losses is presented as a reduction to amortized cost of the financial asset in the consolidated balance sheet and changes to the estimate for expected credit losses are recognized through net investment gains (losses). Loans receivable are reported net of an allowance for expected credit losses of $4 million and $2 million as of ~~both March 31,~~September 30, 2023 and December 31, 2022, respectively.

Fair Value Measurements. The Company’s fixed maturity available for sale securities, equity securities, and its arbitrage 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 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 ~~March 31,~~September 30, 2023:


($ in thousands)	($ in thousands)	Carrying Value		Percent of Total		($ in thousands)	Carrying Value		Percent of Total

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 ~~March 31,~~September 30, 2023, 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 and subordination levels. Discount rates are adjusted to reflect illiquidity where appropriate. These securities were classified as Level 3.

The Company reported net income to common stockholders of ~~$294~~$984 million in 2023 compared to ~~$591~~$999 million in 2022. The ~~$297~~$15 million ~~decrease~~reduction in net income was primarily due to an after-tax reduction in net investment gains of ~~$270~~$69 million mainly due to the gain on sale of a real estate investment in 2022, ~~and the reduced gain from change in market value on equity securities,~~ an after-tax ~~reduction~~decrease in ~~underwriting income~~foreign currency gains of ~~$31~~$66 million ~~primarily~~mainly due to ~~increased storm and property losses,~~lower strengthening of the U.S. dollar against other currencies in 2023, an increase of ~~$17~~$27 million in tax expense due to a change in the effective tax rate, an after-tax increase in ~~foreign currency losses of $11 million mainly due to the weakening of the U.S. dollar against U.K. sterling and Euro in 2023, an after-tax increase in~~ corporate expenses of ~~$10~~$23 million primarily due to increased ~~performance-based compensation~~compensation-related costs and an after-tax decrease in profits from non-insurance businesses of $1$5 million, partially offset by an after-tax increase in net investment income of ~~$39~~$151 million primarily due to rising interest rates and a larger investment portfolio ~~related to~~of fixed maturity securities, an after-tax increase in underwriting income of $19 million, an after-tax reduction in minority interest of $3 million and an after-tax reduction in interest expense of $2 million due to debt repayments in ~~2022 and an after-tax increase in insurance service income of $2 million.~~2022. The number of weighted average diluted shares decreased by ~~1.8~~5.5 million for 2023 compared to 2022, mainly reflecting shares repurchased in ~~the the first quarter of~~ 2023.

Premiums. Gross premiums written were ~~$3,049~~$9,739 million in 2023, an increase of 7%8% from ~~$2,860~~$8,994 million in 2022. The increase was due to a ~~$167~~$683 million increase in the Insurance segment and a ~~$22~~$62 million increase in the Reinsurance & Monoline

3740

Excess segment. Approximately ~~79%~~80% of premiums expiring in 2023 were renewed, and 82% of premiums expiring in 2022 were renewed.

Average renewal premium rates for insurance and facultative reinsurance increased 7.2% in 2023 when adjusted for changes in exposures, and increased 8.3% excluding workers' compensation.

A summary of gross premiums written in 2023 compared with 2022 by line of business within each business segment follows:

•Insurance - gross premiums increased 7%9% to ~~$2,652~~$8,659 million in 2023 from ~~$2,485~~$7,976 million in 2022. Gross premiums increased ~~$94~~$360 million (12%) for other liability, $325 million (18%) for short-tail lines, $101 million (10%) for ~~other liability, $80~~commercial automobile and $1 million ~~(14%) for short-tail lines, $21 million (7%) for commercial auto and $8 million (3%~~(less than 1%) for workers' compensation, partially offset by a reduction of ~~$36~~$104 million ~~(9%~~(8%) for professional liability.

•Reinsurance & Monoline Excess - gross premiums increased 6% to ~~$397~~$1,080 million in 2023 from ~~$375~~$1,018 million in 2022. Gross premiums increased ~~$12~~$54 million ~~(12%) for monoline excess, $6 million (9%~~(28%) for property reinsurance and $4$22 million (10%) for monoline excess, partially offset by a reduction of $14 million (2%) for casualty reinsurance.

Net premiums written were ~~$2,575~~$8,235 million in 2023, an increase of 7%9% from ~~$2,413~~$7,576 million in 2022. Ceded reinsurance premiums as a percentage of gross written premiums were 15% in 2023 and 16% in ~~both 2023 and~~ 2022.

Premiums earned increased ~~11%~~9% to ~~$2,491~~$7,686 million in 2023 from ~~$2,249~~$7,048 million in 2022. 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 2023 are related to business written during both 2023 and 2022. Audit premiums were ~~$91~~$271 million in 2023 compared with ~~$70~~$219 million in 2022 due to an increase in exposures.

The Company maintained the shortened duration of its fixed maturity security portfolio, thereby reducing the potential impact of mark-to-market on the portfolio and positioning the Company to react quickly to changes in the current interest rate environment. We expect investment income to increase as we reinvest our fixed maturity portfolio at the current higher rates. Average invested assets, at cost (including cash and cash equivalents), were ~~$25.7~~$26.1 billion in 2023 up ~~8.3%~~8.1% from ~~$23.7~~$24.2 billion in 2022.

Insurance Service Fees. The Company earns fees from an insurance distribution business (part of which was sold in June 2023), a third-party administrator and as a servicing carrier of workers' compensation assigned risk plans for certain states. Insurance service fees ~~increased to $33~~were $81 million in 2023 ~~from $28~~and $82 million in ~~2022, mainly due to organic growth within the business.~~2022.

Net Realized and Unrealized Gains on Investments. The Company buys and sells securities and other investment assets on a regular basis in order to maximize its total return on investments. Decisions to sell securities and other investment assets are based on management’s view of the underlying fundamentals of specific investments as well as management’s expectations

regarding interest rates, credit spreads, currency values and general economic conditions. Net realized and unrealized gains on investments were ~~$23~~$50 million in 2023 compared with ~~$370~~$140 million in 2022. The gains of ~~$23~~$50 million in 2023 reflected annet realized gains on investments of $5 million (primarily a pre-tax net realized gain of $88 million on the sale of the property

and casualty insurance services division of Breckenridge IS, Inc., partially offset by the impairment of $72 million recognized on the real estate investments) and an increase in unrealized gains on equity securities of ~~$43 million partially offset by net realized losses on investments of $20~~$45 million. The gains of ~~$370~~$140 million in 2022 reflected net realized gains on investments of ~~$277~~$228 million (primarily a $251 million net gain from the sale of a real estate investment in London after transaction expenses and the foreign currency impact, including the reversal of the currency translation adjustment)~~, and~~ partially offset by an increase in unrealized ~~gains~~losses on equity securities of ~~$93~~$89 million.

Change in Allowance for Expected Credit Losses on Investments. Based on credit factors, the allowance for expected credit losses is increased or decreased depending on the percentage of unrealized loss relative to amortized cost by security, changes in rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. For the three months ended March 31, 2023, the pre-tax change in allowance for expected credit losses on investments decreased by $399 thousand ($315 thousand after-tax), which is reflected in net investment gains, primarily due to change in estimate. For the three months ended March 31, 2022, theThe pre-tax change in allowance for expected credit losses on investments increased by $4$11 million ($39 million after-tax), and $12 million ($10 million after-tax) in 2023 and 2022, respectively, which isare both reflected in net investment gains (losses), primarily due to change in estimate.

Revenues from non-insurance businesses were ~~$124~~$375 million in 2023 and ~~$98~~$345 million in 2022. The increase mainly relates to aviation-related business and the commercial and residential textile business, which we acquired in 2022, partially offset by the decrease of promotional merchandise and existing textile business.

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 three months ended September 30, 2023 and 2022:


(In thousands, except per share data)	2023		2022
Net income to common stockholders	$	333,586	$	228,879
Weighted average diluted shares	271,439		279,642
Net income per diluted share	$	1.23	$	0.82

The Company reported net income to common stockholders of $334 million in 2023 compared to $229 million in 2022. The $105 million increase in net income was primarily due to an after-tax increase in net investment income of $54 million primarily due to rising interest rates and a larger investment portfolio of fixed maturity securities, an after-tax increase in underwriting income of $53 million mainly due to the growth in premium rates, an after-tax decrease in net investment losses of $20 million mainly due to the change in market value on equity securities, and an after-tax reduction in minority interest of $2 million, partially offset by an after-tax decrease in foreign currency gains of $15 million mainly due to lower strengthening of the U.S. dollar against other currencies in 2023, an after-tax increase in corporate expenses of $5 million due to increased compensation-related costs, an increase of $3 million in tax expense due to a change in the effective tax rate and an after-tax decrease in profits from insurance service income of $1 million. The number of weighted average diluted shares decreased by 8.2 million for 2023 compared to 2022, mainly reflecting shares repurchased in 2023.

Premiums. Gross premiums written were $3,353 million in 2023, an increase of 9% from $3,082 million in 2022. The increase was due to a $271 million increase in the Insurance segment and a $222 thousand increase in the Reinsurance & Monoline Excess segment. Approximately 80.5% of premiums expiring in 2023 were renewed, and 81% of premiums expiring in 2022 were renewed.

Average renewal premium rates for insurance and facultative reinsurance increased 7.2% in 2023 when adjusted for changes in exposures, and increased 8.5% excluding workers' compensation.

A summary of gross premiums written in 2023 compared with 2022 by line of business within each business segment follows:

•Insurance - gross premiums increased 10% to $2,991 million in 2023 from $2,720 million in 2022. Gross premiums increased $135 million (13%) for other liability, $122 million (20%) for short-tail lines, and $58 million (16%) for commercial automobile, and decreased $40 million (9%) for professional liability and $4 million (1%) for workers' compensation.

•Reinsurance & Monoline Excess - gross premiums remained flat in 2023 with 2022 at $362 million. Gross premiums increased $9 million (11%) for property reinsurance and $9 million (12%) for monoline excess, and decreased $18 million (9%) for casualty reinsurance.

Net premiums written were $2,848 million in 2023, an increase of 11% from $2,577 million in 2022. Ceded reinsurance premiums as a percentage of gross written premiums were 15% in 2023 and 16% in 2022.

Premiums earned increased 8% to $2,642 million in 2023 from $2,442 million in 2022. 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 2023 are related to business written during both 2023 and 2022. Audit premiums were $88 million in 2023 compared with $77 million in 2022 due to an increase in exposures.

Net Investment Income. Following is a summary of net investment income for the three months ended September 30, 2023 and 2022:

Investment expenses	(1,837)		(2,327)		—		—
Total	$	270,944	$	202,816	4.1	%	3.3	%

Net investment income increased 34% to $271 million in 2023 from $203 million in 2022 due primarily to a $94 million increase in income from fixed maturity securities mainly driven by rising interest rates and a larger investment portfolio, a $7 million increase from arbitrage trading account (including investment income from trading account receivables from brokers and clearing organizations) and a $1 million reduction from investment expenses, partially offset by a $32 million decrease in income from investment funds primarily due to real estate funds and transportation funds and a $2 million decrease from equity securities. The Company maintained the short duration of its fixed maturity security portfolio, thereby reducing the potential impact of mark-to-market on the portfolio and positioning the Company to react quickly to changes in the current interest rate environment. We expect investment income to increase as we reinvest our fixed maturity portfolio at the current higher rates. Average invested assets, at cost (including cash and cash equivalents), were $26.7 billion in 2023 and $24.6 billion in 2022.

Insurance Service Fees. The Company earns fees from an insurance distribution business, a third-party administrator and as a servicing carrier of workers' compensation assigned risk plans for certain states.

Net realized and unrealized losses on investments were $41 million in 2023 and $66 million in 2022. The losses of $41 million in

2023 reflected net realized losses on investments of $22 million (primarily due to an impairment of $21 million recognized on a real estate investment) and an increase in unrealized losses on equity securities of $19 million. The losses of $66 million in 2022 reflected net realized losses on investments of $16 million (primarily due to foreign exchange losses on investments) and an increase in unrealized losses on equity securities of $50 million.

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. In addition to fixed maturity securities, the Company invests 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).

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 or losses; however, there is no reason to expect these gains or losses to continue in future periods.

Equity Securities. Equity securities primarily represent investments in common and preferred stocks in companies with potential growth opportunities in different sectors, mainly in the financial institutions, energy and ~~energy~~technology sectors.

Investment Funds. At ~~March 31,~~September 30, 2023, the carrying value of investment funds was ~~$1,602 million,~~$1.6 billion, including investments in financial services funds of ~~$445~~$430 million, other funds of ~~$367~~$403 million (which includes a deferred compensation trust asset of ~~$34~~$31 million), transportation funds of ~~$337~~$336 million, real estate funds of ~~$217~~$191 million, infrastructure funds of ~~$119~~$125 million and energy funds of ~~$117~~$115 million. Investment funds are generally reported on a one-quarter lag.

Real Estate. Real estate is directly owned property held for investment. At ~~March 31,~~September 30, 2023, real estate properties in operation included a long-term ground lease in Washington D.C., an office complex in New York City and the completed portion of a mixed-use project in Washington D.C. In addition, part of the previously mentioned mixed-use project in Washington D.C. is under development. The Company expects to fund further development costs for the project with a combination of its own funds and external financing. The Company recognized impairments on real estate of $21 million and $72 million in the three months and nine months ended September 30, 2023, respectively. During the first quarter of 2022, the Company sold an office building in London.

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 (net of allowance for expected credit losses), had an amortized cost of ~~$195~~$178 million and an aggregate fair value of ~~$187~~$174 million at ~~March 31,~~September 30, 2023. The amortized cost of loans receivable is net of an allowance for expected credit losses of $2$4 million as of ~~March 31,~~September 30, 2023. Loans receivable include real estate loans of ~~$176~~$160 million that are secured by commercial and residential real estate located primarily in London and

New York. Real estate loans generally earn interest at fixed or stepped interest rates and have maturities through 2026. Loans receivable include commercial loans of ~~$19~~$18 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 effective duration of the investment portfolio and the approximate duration of its liabilities (i.e., policy claims and debt obligations). The effective duration for the fixed maturity portfolio (including cash and cash equivalents) was 2.4 years at both ~~March 31,~~September 30, 2023 and December 31, 2022.

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 ~~decreased~~increased to ~~$445~~$2,231 million in the ~~three~~nine months ended ~~March 31,~~September 30, 2023 from ~~$478~~$1,773 million in the ~~three~~nine months ended ~~March 31,~~September 30, 2022, primarily due to increased ~~loss and loss expense payments~~premium receipts, partially offset by an increase in ~~premium receipts.~~loss and loss 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 generally targets an average duration for its investment portfolio that is within 1.5 years 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 ~~79%~~80% invested in cash, cash equivalents and marketable fixed maturity securities as of ~~March 31,~~September 30, 2023. 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 ~~March 31,~~September 30, 2023, the Company had senior notes, subordinated debentures and other debt outstanding with a carrying value of $2,837 million and a face amount of $2,865 million. In the first quarter of 2022, the Company repaid at maturity its $77 million aggregate principal amount of 8.7% senior notes in January and its $350 million aggregate principal amount of 4.625% senior notes in March. The maturities of the outstanding debt are $5$7 million in 2024, $5$3 million in 2025, $250 million in 2037, $350 million in 2044, $470 million in 2050, $400 million in 2052, $185 million in 2058, $300 million in 2059, $250 million in 2060, and $650 million in 2061.

On April 1, 2022, the Company entered into a senior unsecured revolving credit facility that provides for revolving, unsecured borrowings up to an aggregate of $300 million with a $50 million sublimit for letters of credit. The Company may increase the amount available under the facility to a maximum of $500 million subject to obtaining lender commitments for the increase and other customary conditions. Borrowings under the facility may be used for working capital and other general corporate purposes. All borrowings under the facility must be repaid by April 1, 2027, except that letters of credit outstanding on that date may remain outstanding until April 1, 2028 (or such later date approved by all lenders). Our ability to utilize the facility is conditioned on the satisfaction of representations, warranties and covenants that are customary for facilities of this type. As of ~~March 31,~~September 30, 2023, there were no borrowings outstanding under the facility.
