A.    Accounting Policies

Basis of Presentation   The accompanying consolidated financial statements for American Financial Group, Inc. and its subsidiaries (“AFG”) are unaudited; however, management believes that all adjustments (consisting only of normal recurring accruals unless otherwise disclosed herein) necessary for fair presentation have been made. The results of operations for interim periods are not necessarily indicative of results to be expected for the year. The financial statements have been prepared in accordance with the instructions to Form 10-Q and, therefore, do not include all information and footnotes necessary to be in conformity with U.S. generally accepted accounting principles (“GAAP”).

Certain reclassifications have been made to prior periods to conform to the current year’s presentation. All significant intercompany balances and transactions have been eliminated. The results of operations of companies since their formation or acquisition are included in the consolidated financial statements. Events or transactions occurring subsequent to June 30, 2023, and prior to the filing of this Form 10-Q, have been evaluated for potential recognition or disclosure herein.

The preparation of the financial statements requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Changes in circumstances could cause actual results to differ materially from those estimates.

Fair Value Measurements   Accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants on the measurement date. The standards establish a hierarchy of valuation techniques based on whether the assumptions that market participants would use in pricing the asset or liability (“inputs”) are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect AFG’s assumptions about the assumptions market participants would use in pricing the asset or liability. AFG did not have any material nonrecurring fair value measurements in the first six months of 2023.

Investments   Equity securities other than those accounted for under the equity method are reported at fair value with holding gains and losses generally recorded in realized gains (losses) on securities. However, AFG records holding gains and losses on limited partnerships and similar investments that do not qualify for equity method accounting (and are therefore carried at fair value), and certain other securities classified at purchase as “fair value through net investment income” in net investment income.

Fixed maturity securities classified as “available for sale” are reported at fair value with unrealized gains and losses included in accumulated other comprehensive income (“AOCI”) in AFG’s Balance Sheet. Fixed maturity securities classified as “trading” are reported at fair value with changes in unrealized holding gains or losses during the period included in net investment income. Mortgage loans (net of any allowance) are carried primarily at the aggregate unpaid balance.

Realized gains or losses on the disposal of fixed maturity securities are determined on the specific identification basis. Premiums and discounts on fixed maturity securities are amortized using the effective interest method. Mortgage-backed securities (“MBS”) are amortized over a period based on estimated future principal payments, including prepayments. Prepayment assumptions are reviewed periodically and adjusted to reflect actual prepayments and changes in expectations.

AMERICAN FINANCIAL GROUP, INC. 10-Q

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED

Limited partnerships and similar investments are generally accounted for using the equity method of accounting. Under the equity method, AFG records its share of the earnings or losses of the investee based on when it is reported by the investee in its financial statements rather than in the period in which the investee declares a dividend. AFG’s share of the earnings or losses from equity method investments is generally recorded on a quarter lag due to the timing of the receipt of the investee’s financial statements. AFG’s equity in the earnings (losses) of limited partnerships and similar investments is included in net investment income.

Credit Losses on Fixed Maturity Investments   When a decline in the value of an available for sale fixed maturity is considered to be other-than-temporary at the balance sheet date, an allowance for credit losses (impairment), including any write-off of accrued interest, is charged to earnings (included in realized gains (losses) on securities). If management can assert that it does not intend to sell the security and it is not more likely than not that it will have to sell it before recovery of its amortized cost basis (net of allowance), then the impairment is separated into two components: (i) the allowance related to credit losses (recorded in earnings) and (ii) the amount related to all other factors (recorded in other comprehensive income). The credit-related portion is measured by comparing a security’s amortized cost to the present value of its current expected cash flows discounted at its effective yield prior to the charge. The allowance is limited to the difference between a security’s amortized cost basis and its fair value. Subsequent increases or decreases in expected credit losses are recorded immediately in net earnings through realized gains (losses). If management intends to sell an impaired security, or it is more likely than not that it will be required to sell the security before recovery, an impairment is recorded in earnings to reduce the amortized cost (net of allowance) of that security to fair value.

Credit Losses on Financial Instruments Measured at Amortized Cost   Credit-related impairments for financial instruments measured at amortized cost (mortgage loans, premiums receivable and reinsurance recoverables) reflect estimated credit losses expected over the life of an exposure or pool of exposures. The estimate of expected credit losses considers historical information, current information, as well as reasonable and supportable forecasts, including estimates of prepayments. Expected credit losses, and subsequent increases or decreases in such expected losses, are recorded immediately through net earnings as an allowance that is deducted from the amortized cost basis of the financial asset, with the net carrying value of the financial asset presented on the balance sheet at the amount expected to be collected.

Derivatives   Derivatives included in AFG’s Balance Sheet are recorded at fair value. Changes in fair value of derivatives are included in earnings unless the derivatives are designated and qualify as highly effective cash flow hedges. AFG’s derivatives that do not qualify for hedge accounting under GAAP consist primarily of components of certain fixed maturity securities (convertible fixed maturities and interest-only and principal-only MBS) and a total return swap related to its deferred compensation obligations to employees.

To qualify for hedge accounting, at the inception of a derivative contract, AFG formally documents the relationship between the terms of the hedge and the hedged items and its risk management objective. This documentation includes defining how hedge effectiveness is evaluated at the inception date and over the life of the derivative.

Changes in the fair value of derivatives that are designated and qualify as highly effective cash flow hedges are recorded in AOCI and are reclassified into earnings when the variability of the cash flows from the hedged items impacts earnings. When the change in the fair value of a qualifying cash flow hedge is included in earnings, it is included in the same line item in the statement of earnings as the cash flows from the hedged item. AFG uses interest rate swaps that are designated and qualify as highly effective cash flow hedges to mitigate interest rate risk related to certain floating-rate securities.

Goodwill   Goodwill represents the excess of cost of subsidiaries over AFG’s equity in their underlying net assets at the date of acquisition. Goodwill is not amortized, but is subject to an impairment test at least annually. An entity is not required to complete the quantitative annual goodwill impairment test on a reporting unit if the entity elects to perform a qualitative analysis and determines that it is more likely than not that the reporting unit’s fair value exceeds its carrying amount.

Reinsurance   Amounts recoverable from reinsurers are estimated in a manner consistent with the claim liability associated with the reinsured policies. AFG reports as assets (i) the estimated reinsurance recoverable on paid and unpaid losses, including an estimate for losses incurred but not reported, and (ii) amounts paid or due to reinsurers applicable to the unexpired terms of policies in force. Payable to reinsurers includes ceded premiums due to reinsurers, as well as ceded premiums retained by AFG under contracts to fund ceded losses as they become due. AFG also assumes reinsurance from other companies. Earnings on reinsurance assumed is recognized based on information received from ceding companies.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED

Deferred Policy Acquisition Costs (“DPAC”)   Policy acquisition costs (principally commissions, premium taxes and certain underwriting and policy issuance costs) directly related to the successful acquisition or renewal of an insurance contract are deferred. DPAC is limited based upon recoverability without any consideration for anticipated investment income and is charged against income ratably over the terms of the related policies. A premium deficiency is recognized if the sum of expected claims costs, claims adjustment expenses and unamortized acquisition costs exceed the related unearned premiums. A premium deficiency is first recognized by charging any unamortized acquisition costs to expense to the extent required to eliminate the deficiency. If the premium deficiency is greater than unamortized acquisition costs, a liability is accrued for the excess deficiency and reported with unpaid losses and loss adjustment expenses.

Managed Investment Entities   A company is considered the primary beneficiary of, and therefore must consolidate, a variable interest entity (“VIE”) based primarily on its ability to direct the activities of the VIE that most significantly impact that entity’s economic performance and the obligation to absorb losses of, or receive benefits from, the entity that could potentially be significant to the VIE.

AFG manages, and has investments in, collateralized loan obligations (“CLOs”) that are VIEs (see Note F — “Managed Investment Entities”). AFG has determined that it is the primary beneficiary of these CLOs because (i) its role as asset manager gives it the power to direct the activities that most significantly impact the economic performance of the CLOs and (ii) through its investment in the CLO debt tranches, it has exposure to CLO losses (limited to the amount AFG invested) and the right to receive CLO benefits that could potentially be significant to the CLOs.

Because AFG has no right to use the CLO assets and no obligation to pay the CLO liabilities, the assets and liabilities of the CLOs are shown separately in AFG’s Balance Sheet. AFG has elected the fair value option for reporting on the CLO assets and liabilities to improve the transparency of financial reporting related to the CLOs. The net gain or loss from accounting for the CLO assets and liabilities at fair value is presented separately in AFG’s Statement of Earnings.

The fair values of a CLO’s assets may differ from the separately measured fair values of its liabilities even though the CLO liabilities only have recourse to the CLO assets. AFG has set the carrying value of the CLO liabilities equal to the fair value of the CLO assets (which have more observable fair values) as an alternative to reporting those liabilities at a separately measured fair value. CLO earnings attributable to AFG’s shareholders are measured by the change in the fair value of AFG’s investments in the CLOs and management fees earned.

At June 30, 2023, assets and liabilities of managed investment entities included $105 million in assets and $86 million in liabilities of a temporary warehousing entity that was established to provide AFG the ability to form a new CLO. At closing, all warehoused assets will be transferred to the new CLO and the liabilities will be repaid.

Unpaid Losses and Loss Adjustment Expenses   The net liabilities stated for unpaid claims and for expenses of investigation and adjustment of unpaid claims represent management’s best estimate and are based upon (i) the accumulation of case estimates for losses reported prior to the close of the accounting period on direct business written; (ii) estimates received from ceding reinsurers and insurance pools and associations; (iii) estimates of unreported losses (including possible development on known claims) based on past experience; (iv) estimates based on experience of expenses for investigating and adjusting claims; and (v) the current state of the law and coverage litigation. Establishing reserves for asbestos, environmental and other mass tort claims involves considerably more judgment than other types of claims due to, among other things, inconsistent court decisions, an increase in bankruptcy filings as a result of asbestos-related liabilities, novel theories of coverage, and judicial interpretations that often expand theories of recovery and broaden the scope of coverage.

Loss reserve liabilities are subject to the impact of changes in claim amounts and frequency and other factors. Changes in estimates of the liabilities for losses and loss adjustment expenses are reflected in the statement of earnings in the period in which determined. Despite the variability inherent in such estimates, management believes that the liabilities for unpaid losses and loss adjustment expenses are adequate and reasonable.

Debt Issuance Costs   Debt issuance costs related to AFG’s outstanding debt are presented in its Balance Sheet as a direct reduction in the carrying value of long-term debt and are amortized over the life of the related debt using the effective interest method as a component of interest expense. Debt issuance costs related to AFG’s revolving credit facilities are included in other assets in AFG’s Balance Sheet.

Leases   Leases for terms of longer than one year are recognized as assets and liabilities for the rights and obligations created by those leases on the balance sheet based on the present value of contractual cash flows.

At June 30, 2023 AFG has a $190 million lease liability included in other liabilities and a lease right-of-use asset of $167 million included in other assets compared to $116 million and $103 million, respectively, at December 31, 2022. The increase in the lease liability and right-of-use asset is due primarily to the renewal of AFG’s largest office lease which extended the term for an additional 10 years.

Premium Recognition   Property and casualty premiums are earned generally over the terms of the policies on a pro rata basis. Unearned premiums represent that portion of premiums written, which is applicable to the unexpired terms of policies in force. On reinsurance assumed from other insurance companies or written through various underwriting organizations, unearned premiums are based on information received from such companies and organizations.

Income Taxes   Deferred income taxes are calculated using the liability method. Under this method, deferred income tax assets and liabilities are determined based on differences between financial reporting and tax bases and are measured using enacted tax rates. A valuation allowance is established to reduce total deferred tax assets to an amount that will more likely than not be realized. The effect of a change in tax rates on deferred tax assets and liabilities is recorded in net earnings in the period that includes the enactment date.

AFG recognizes the tax benefits of uncertain tax positions only when the position is more likely than not to be sustained under examination by the appropriate taxing authority. Interest and penalties on AFG’s reserve for uncertain tax positions are recognized as a component of tax expense.

Stock-Based Compensation   All share-based grants are recognized as compensation expense on a straight-line basis over their vesting periods based on their calculated fair value at the date of grant.

AFG records excess tax benefits or deficiencies for share-based payments through income tax expense in the statement of earnings. In addition, AFG accounts for forfeitures of awards when they occur.

Benefit Plans   AFG provides retirement benefits to qualified employees of participating companies through the AFG 401(k) Retirement and Savings Plan, a defined contribution plan. AFG makes all contributions to the retirement fund portion of the plan and matches a percentage of employee contributions to the savings fund. Company contributions are expensed in the year for which they are declared. AFG and many of its subsidiaries provide health care and life insurance benefits to eligible retirees. AFG also provides postemployment benefits to former or inactive employees (primarily those on disability) who were not deemed retired under other company plans. The projected future cost of providing these benefits is expensed over the period employees earn such benefits.

Earnings Per Share   Although basic earnings per share only considers shares of common stock outstanding during the period, the calculation of diluted earnings per share includes the following adjustments to weighted average common shares related to stock-based compensation plans: second quarter 2023 and 2022 — 0.1 million and 0.2 million; first six months of 2023 and 2022 — 0.1 million and 0.6 million.

There were no anti-dilutive potential common shares for the second quarter or the first six months of 2023 or 2022.

Statement of Cash Flows   For cash flow purposes, “investing activities” are defined as making and collecting loans and acquiring and disposing of debt or equity instruments, property and equipment and businesses. “Financing activities” include obtaining resources from owners and providing them with a return on their investments, borrowing money and repaying amounts borrowed. All other activities are considered “operating.” Short-term investments having original maturities of three months or less when purchased are considered to be cash equivalents for purposes of the financial statements.

B.    Segments of Operations

AFG manages its business as two segments: Property and casualty insurance and Other, which includes holding company costs and operations attributable to the noncontrolling interests of the managed investment entities.

AFG reports its property and casualty insurance business in the following Specialty sub-segments: (i) Property and transportation, which includes physical damage and liability coverage for buses and trucks and other specialty

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED

transportation niches, inland and ocean marine, agricultural-related products and other commercial property coverages, (ii) Specialty casualty, which includes primarily excess and surplus, executive and professional liability, general liability, umbrella and excess liability, specialty coverages in targeted markets, customized programs for small to mid-sized businesses and workers’ compensation insurance, and (iii) Specialty financial, which includes risk management insurance programs for lending and leasing institutions (including equipment leasing and collateral and lender-placed mortgage property insurance), fidelity and surety products and trade credit insurance. Premiums and underwriting profit included under Other specialty represent business assumed by AFG’s internal reinsurance program from the operations that make up AFG’s other Specialty sub-segments and amortization of a deferred gain on a retroactive reinsurance transaction related to the sale of a business. AFG’s reportable segments and their components were determined based primarily upon similar economic characteristics, products and services.

The following tables (in millions) show AFG’s revenues and earnings before income taxes by segment and sub-segment.

C.    Fair Value Measurements

Accounting standards for measuring fair value are based on inputs used in estimating fair value. The three levels of the hierarchy are as follows:

Level 1 — Quoted prices for identical assets or liabilities in active markets (markets in which transactions occur with sufficient frequency and volume to provide pricing information on an ongoing basis). AFG’s Level 1 financial instruments consist primarily of publicly traded equity securities, highly liquid government bonds for which quoted market prices in active markets are available and short-term investments of managed investment entities.

Level 2 — Quoted prices for similar instruments in active markets; quoted prices for identical or similar assets or liabilities in inactive markets (markets in which there are few transactions, the prices are not current, price quotations vary substantially over time or among market makers, or in which little information is released publicly); and valuations based on other significant inputs that are observable in active markets. AFG’s Level 2 financial instruments include corporate and municipal fixed maturity securities, asset-backed securities (“ABS”), mortgage-backed securities (“MBS”), certain non-affiliated common stocks and investments of managed investment entities priced using observable inputs. Level 2 inputs include benchmark yields, reported trades, corroborated broker/dealer quotes, issuer spreads and benchmark securities. When non-binding broker quotes can be corroborated by comparison to similar securities priced using observable inputs, they are classified as Level 2.

Level 3 — Valuations derived from market valuation techniques generally consistent with those used to estimate the fair values of Level 2 financial instruments in which one or more significant inputs are unobservable or when the market for a security exhibits significantly less liquidity relative to markets supporting Level 2 fair value measurements. The unobservable inputs may include management’s own assumptions about the assumptions market participants would use based on the best information available at the valuation date. Financial instruments whose fair value is estimated based on non-binding broker quotes or internally developed using significant inputs not based on, or corroborated by, observable market information are classified as Level 3.

The contingent consideration liability (included in other liabilities in AFG’s Balance Sheet) relates primarily to AFG’s acquisition of Verikai in December 2021. This estimated fair value of this liability is evaluated at each balance sheet date with changes in fair value recognized in net earnings. To estimate the fair value of the contingent consideration liability related to the Verikai acquisition ($23 million at June 30, 2023), AFG uses a weighted probability-based income approach which includes significant unobservable inputs and is classified as Level 3. There was no change to the estimated fair value of this liability during the first six months of 2023.

As discussed in Note A — “Accounting Policies — Managed Investment Entities,” AFG has set the carrying value of its CLO liabilities equal to the fair value of the CLO assets (which have more observable fair values) as an alternative to reporting those liabilities at separately measured fair values. As a result, the CLO liabilities are categorized within the fair value hierarchy on the same basis (proportionally) as the related CLO assets. Since the portion of the CLO liabilities allocated to Level 3 is derived from the fair value of the CLO assets, these amounts are excluded from the progression of Level 3 financial instruments.

AFG’s management is responsible for the valuation process and uses data from outside sources (including nationally recognized pricing services and broker/dealers) in establishing fair value. AFG’s internal investment professionals are a group of approximately 20 investment professionals whose primary responsibility is to manage AFG’s investment portfolio. These professionals monitor individual investments as well as overall industries and are active in the financial markets on a daily basis. The group is led by AFG’s chief investment officer, who reports directly to one of AFG’s Co-CEOs. Valuation techniques utilized by pricing services and prices obtained from external sources are reviewed by AFG’s internal investment professionals who are familiar with the securities being priced and the markets in which they trade to ensure the fair value determination is representative of an exit price. To validate the appropriateness of the prices obtained, these investment managers consider widely published indices (as benchmarks), recent trades, changes in interest rates, general economic conditions and the credit quality of the specific issuers. In addition, AFG communicates directly with the pricing services regarding the methods and assumptions used in pricing, including verifying, on a test basis, the inputs used by the service to value specific securities.

Approximately 7% of the total assets carried at fair value at June 30, 2023, were Level 3 assets. Approximately 10% ($117 million) of those Level 3 assets were priced using non-binding broker quotes, for which there is a lack of transparency as to the inputs used to determine fair value. Details as to the quantitative inputs are neither provided by the brokers nor otherwise reasonably obtainable by AFG. Approximately 3% ($37 million) of the Level 3 assets were priced by pricing services where either a single price was not corroborated, prices varied enough among the providers, or other market factors led management to determine these securities be classified as Level 3 assets. Approximately 27% ($316 million) of the Level 3 assets were equity investments in limited partnerships and similar investments that do not

qualify for equity method accounting whose prices were determined based on financial information provided by the limited partnerships.

Internally developed prices for fixed maturities are estimated using a variety of inputs, including appropriate credit spreads over the treasury yield (of a similar duration), trade information and prices of comparable securities and other security specific features (such as optional early redemption). Internally developed Level 3 asset fair values represent approximately 60% ($690 million) of the total fair value of Level 3 assets at June 30, 2023. Approximately 67% ($462 million) of these internally developed Level 3 assets are priced using a pricing model that uses a discounted cash flow approach to estimate the fair value of fixed maturity securities. The credit spread applied by management is the significant unobservable input of the pricing model. In instances where the security is currently callable at par value and the pricing model suggests a higher price, management caps the fair value at par value. Approximately 18% ($123 million) of the internally developed Level 3 assets are equity securities which are priced primarily using internal models with some inputs that are not market observable. Management believes that any justifiable changes in unobservable inputs used to determine internally developed fair values would not have resulted in a material change in AFG’s financial position.

(*)92% of the carrying value relates to underlying investments in multi-family properties at both June 30, 2023 and December 31, 2022.

The earnings (losses) from these investments are generally reported on a quarter lag due to the timing required to obtain the necessary information from the funds. AFG regularly reviews and discusses fund performance with the fund managers to corroborate the reasonableness of the underlying reported asset values and to assess whether any events have occurred within the lag period that may materially affect the valuation of these investments.

With respect to partnerships and similar investments, AFG had unfunded commitments of $407 million and $396 million as of June 30, 2023 and December 31, 2022, respectively.

At June 30, 2023, the gross unrealized losses on fixed maturities of $627 million relate to approximately 1,800 securities. Investment grade securities (as determined by nationally recognized rating agencies) represented approximately 95% of the gross unrealized loss and 95% of the fair value of securities with unrealized losses.

To evaluate fixed maturities for expected credit losses (impairment), management considers whether the unrealized loss is credit-driven or a result of changes in market interest rates, the extent to which fair value is less than cost basis, historical operating, balance sheet and cash flow data from the issuer, third party research and communications with industry specialists and discussions with issuer management.

AFG analyzes its MBS for expected credit losses (impairment) each quarter based upon expected future cash flows. Management estimates expected future cash flows based upon its knowledge of the MBS market, cash flow projections (which reflect loan to collateral values, subordination, vintage and geographic concentration) received from independent sources, implied cash flows inherent in security ratings and analysis of historical payment data.

Management believes AFG will recover its cost basis (net of any allowance) in the securities with unrealized losses and that AFG has the ability to hold the securities until they recover in value and had no intent to sell them at June 30, 2023.

E.    Derivatives

As discussed under “Derivatives” in Note A — “Accounting Policies,” AFG uses derivatives to mitigate certain market risks related to its investment portfolio and deferred compensation obligations to employees.

The following table presents the classification of derivative assets and liabilities included in AFG’s Balance Sheet at fair value (in millions):

		June 30, 2023				December 31, 2022
	Balance Sheet Line	Asset		Liability		Asset		Liability
Derivatives designated and qualifying as cash flow hedges:
Interest rate swaps	Other assets/Other liabilities	$	—	$	41	$	—	$	37
Derivatives not designated as hedging instruments:
Fixed maturities with embedded derivatives	Fixed maturities	92		—		40		—
Total return swap	Other assets/Other liabilities	4		—		—		5
		$	96	$	41	$	40	$	42

AFG’s interest rate swaps are designated and qualify as highly effective cash flow hedges to mitigate interest rate risk related to certain floating-rate securities included in AFG’s portfolio of fixed maturity securities. The purpose of each of these swaps is to effectively convert a portion of AFG’s floating-rate fixed maturity securities to fixed rates by offsetting the variability in cash flows attributable to changes in short-term reference rates (LIBOR or SOFR).

Under the terms of the swaps, AFG receives fixed-rate interest payments in exchange for variable interest payments based on short-term LIBOR or SOFR. The notional amounts of the interest rate swaps generally decline over each swap’s respective life (the swaps expire between July 2024 and July 2028) in anticipation of the expected decline in AFG’s portfolio of fixed maturity securities with floating interest rates based on short-term LIBOR or SOFR. The total outstanding notional amount of AFG’s interest rate swaps was $1.35 billion at June 30, 2023 compared to $1.25 billion at December 31, 2022, reflecting the issuance of four new swaps with a total notional amount of $170 million in the first six months of 2023, partially offset by scheduled amortization. In the second quarter of 2023 and 2022, a loss of $7 million and income of $1 million, respectively, and in the first six months of 2023 and 2022, a loss of $12 million and income of $2 million, respectively, were reclassified from AOCI to net earnings. A collateral receivable supporting these swaps of $68 million and $62 million at June 30, 2023 and December 31, 2022, respectively, is included in other assets in AFG’s Balance Sheet.

AMERICAN FINANCIAL GROUP, INC. 10-Q

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED

The fixed maturities with embedded derivatives consist of convertible fixed maturity securities and interest-only and principal-only MBS. AFG records the change in the fair value of these securities in earnings. These investments are part of AFG’s overall investment strategy and represent a small component of AFG’s overall investment portfolio.

AFG is exposed to fair value changes from certain equity and fixed maturity market-based exposures related to its deferred compensation obligations to certain employees. To mitigate this risk, AFG entered into a total return swap in 2022. A payable of $3 million to return collateral related to this swap is included in other liabilities in AFG’s Balance Sheet at June 30, 2023 and a collateral receivable of $7 million supporting this swap is included in other assets in AFG’s Balance Sheet at December 31, 2022.

The following table summarizes the gains (losses) included in AFG’s Statement of Earnings for changes in the fair value of derivatives for the second quarter and six months ended June 30, 2023 and 2022 (in millions):

		Three months ended June 30,				Six months ended June 30,
	Statement of Earnings Line	2023		2022		2023		2022
Qualifying cash flow hedges - gains (losses) reclassified from AOCI to net earnings:
Interest rate swaps	Net investment income	$	(7)	$	1	$	(12)	$	2
Non-designated hedges - gains (losses) included in net earnings:
Fixed maturities with embedded derivatives	Realized gains (losses) on securities	(4)		(3)		(3)		(8)
Fixed maturities with embedded derivatives	Net investment income	7		—		10		—
Total return swap	Other expenses	3		(4)		9		(4)
Earnings (losses) on non-designated hedges		6		(7)		16		(12)
Total earnings (losses) on derivatives		$	(1)	$	(6)	$	4	$	(10)

Based on forward interest rate curves at June 30, 2023, management estimates that it will reclassify approximately $25 million of pre-tax net losses on interest rate swaps in AOCI to net investment income over the next twelve months. The actual amount will vary based on changes in SOFR.

F.    Managed Investment Entities

AFG is the investment manager and it has investments ranging from 7.4% to 100% of the most subordinate debt tranche of sixteen active collateralized loan obligation entities (“CLOs”), which are considered variable interest entities. AFG also owns portions of the senior debt tranches of certain of these CLOs. Upon formation between 2012 and 2023, these entities issued securities in various senior and subordinate classes and invested the proceeds primarily in secured bank loans, which serve as collateral for the debt securities issued by each CLO. None of the collateral was purchased from AFG. AFG’s investments in the subordinate debt tranches of these entities receive residual income from the CLOs only after the CLOs pay expenses (including management fees to AFG) and interest on and returns of capital to senior levels of debt securities. There are no contractual requirements for AFG to provide additional funding for these entities. AFG has not provided and does not intend to provide any financial support to these entities.

AFG’s maximum exposure to economic loss on the CLOs that it manages is limited to its investment in those CLOs, which had an aggregate fair value of $136 million (including $85 million invested in the most subordinate tranches and $19 million invested in a temporary warehousing entity) at June 30, 2023, and $115 million at December 31, 2022.

In March 2023, AFG formed one new CLO, which issued $407 million face amount of liabilities (including $16 million face amount purchased by AFG). In May 2022, AFG formed one new CLO, which issued $404 million face amount of liabilities (including $13 million face amount purchased by AFG).

(*)Excludes $19 million invested in a temporary warehousing entity at June 30, 2023 that was established to provide AFG the ability to form a new CLO.

The revenues and expenses of the CLOs are separately identified in AFG’s Statement of Earnings, after the elimination of management fees and earnings attributable to AFG as measured by the change in the fair value of AFG’s investments in the CLOs. Selected financial information related to the CLOs is shown below (in millions):

	Three months ended June 30,				Six months ended June 30,
	2023		2022		2023		2022

Management fees paid to AFG	4		4		8		8
CLO earnings (losses) attributable to AFG	5		(12)		6		(14)

(*)Included in revenues in AFG’s Statement of Earnings.

The aggregate unpaid principal balance of the CLOs’ fixed maturity investments exceeded the fair value of the investments by $230 million and $339 million at June 30, 2023 and December 31, 2022, respectively. The aggregate unpaid principal balance of the CLOs’ debt exceeded its carrying value by $353 million and $413 million at those dates. The CLO assets include loans with an aggregate fair value of $5 million at June 30, 2023 and $4 million at December 31, 2022, for which the CLOs are not accruing interest because the loans are in default (aggregate unpaid principal balance of $15 million at June 30, 2023 and $17 million at December 31, 2022).

In addition to the CLOs that it manages, AFG had investments in CLOs that are managed by third parties (therefore not consolidated), which are included in available for sale fixed maturity securities and had a fair value of $1.86 billion at June 30, 2023 and $1.92 billion at December 31, 2022.

G.    Goodwill and Other Intangibles

There were no changes in the goodwill balance of $246 million during the first six months of 2023.

Included in other assets in AFG’s Balance Sheet is $102 million at June 30, 2023 and $108 million at December 31, 2022 in amortizable intangible assets related to acquisitions. These amounts are net of accumulated amortization of $29 million and $24 million, respectively. Amortization of intangibles was $3 million in both the second quarter of 2023 and 2022 and $6 million and $5 million in the first six months of 2023 and 2022, respectively.

J.    Income Taxes

The following is a reconciliation of income taxes at the statutory rate of 21% to the provision for income taxes as shown in AFG’s Statement of Earnings (dollars in millions):

	Three months ended June 30,								Six months ended June 30,

On January 1, 2023, the two major tax provisions of the Inflation Reduction Act (“IRA”) became effective. The IRA created a new corporate alternative minimum tax (“AMT”) based on the earnings that a company reports in its financial statements and imposes a 1% excise tax on corporate stock repurchases. Due to the lack of specific guidance at this time, AFG cannot determine whether it will be subject to the new AMT. Any AMT incurred would be available to offset AFG’s taxes payable under the standard calculation in future periods. Accordingly, the AMT is a timing difference and would result in the recording of an offsetting deferred tax asset with no impact on overall income tax expense. The excise tax on stock repurchases in excess of any issuances is recorded as part of the cost of the repurchases directly in shareholders’ equity.

K.    Contingencies

There have been no significant changes to the matters discussed and referred to in Note N — “Contingencies” of AFG’s 2022 Form 10-K, which covers property and casualty insurance reserves for claims related to environmental exposures, asbestos and other mass tort claims and environmental and occupational injury and disease claims of subsidiaries’ former railroad and manufacturing operations.

L.    Insurance

Property and Casualty Insurance Reserves The following table provides an analysis of changes in the liability for losses and loss adjustment expenses during the first six months of 2023 and 2022 (in millions):

	Six months ended June 30,
	2023		2022
Balance at beginning of year	$	11,974	$	11,074
Less reinsurance recoverables, net of allowance	3,767		3,419
Net liability at beginning of year	8,207		7,655
Provision for losses and LAE occurring in the current period	1,850		1,640
Net decrease in the provision for claims of prior years	(125)		(173)
Total losses and LAE incurred	1,725		1,467
Payments for losses and LAE of:
Current year	(338)		(290)
Prior years	(1,345)		(1,102)
Total payments	(1,683)		(1,392)
Foreign currency translation and other	—		—
Net liability at end of period	8,249		7,730
Add back reinsurance recoverables, net of allowance	3,676		3,471
Gross unpaid losses and LAE included in the balance sheet at end of period	$	11,925	$	11,201

The net decrease in the provision for claims of prior years during the first six months of 2023 reflects (i) lower than anticipated losses in the crop business, lower than expected claim frequency and severity in the trucking business and lower than anticipated claim frequency in the property and inland marine business (within the Property and transportation sub-segment), (ii) lower than anticipated claim severity in the workers’ compensation businesses, lower than expected claim frequency in the executive liability and environmental businesses and favorable reserve development related to COVID-19 losses across several businesses (within the Specialty casualty sub-segment) and (iii) lower than anticipated claim frequency in the trade credit and financial institutions businesses and lower than expected claim frequency and severity in the surety business (within the Specialty financial sub-segment). This favorable development was partially offset by higher than anticipated claim severity in the public sector and excess liability businesses (within the Specialty casualty sub-segment).

The net decrease in the provision for claims of prior years during the first six months of 2022 reflects (i) lower than anticipated losses in the crop business, lower than expected claim frequency in the trucking and ocean marine businesses and at the Singapore branch, lower than expected claim frequency and severity in the aviation business and lower than anticipated claim severity in the property and inland marine business (within the Property and transportation sub-segment), (ii) lower than anticipated claim severity in the workers’ compensation businesses, lower than expected claim frequency in the executive liability business and lower than anticipated claim frequency and severity in the excess and surplus business (within the Specialty casualty sub-segment) and (iii) lower than anticipated claim frequency in the surety, trade credit and financial institutions businesses (within the Specialty financial sub-segment). This favorable development was partially offset by (i) higher than anticipated claim severity in the targeted markets and excess liability businesses (within the Specialty casualty sub-segment) and (ii) net adverse development associated with AFG’s internal reinsurance program (within Other specialty).

M.    Subsequent Event

On July 3, 2023, AFG completed the acquisition of Crop Risk Services (“CRS”) from American International Group (“AIG”). CRS is a primary crop insurance general agent based in Decatur, Illinois, with crop year 2022 gross written premiums of approximately $1.2 billion and was the seventh largest provider of multi-peril crop insurance in the United States based on 2022 premiums. At closing, AFG paid AIG approximately $235 million (based on an estimated $25 million in net tangible assets) using cash on hand. The sale is subject to post-closing adjustments which are expected to be finalized during the third quarter of 2023. The purchase price in excess of the net tangible assets acquired ($210 million) will be recorded as a combination of amortizing intangible assets (primarily related to existing agency relationships) and goodwill. AFG expensed $3 million of acquisition expenses incurred.

AFG’s Great American Insurance Company has been providing crop-hail coverage since 1915 and began writing multi-peril crop insurance in 1980 after Congress authorized the program. Great American’s existing Crop Division generated gross written premiums of approximately $1.8 billion in 2022 and was the fifth largest provider of multi-peril crop insurance in the United States. As part of the AFG organization, CRS will continue to do business in all 37 states in which it currently operates.

Management’s Discussion and Analysis of Financial Condition and Results of Operations — Continued

The forward-looking statements herein are made only as of the date of this report. The Company assumes no obligation to publicly update any forward-looking statements.

OBJECTIVE

The objective of Management’s Discussion and Analysis is to provide a discussion and analysis of the financial statements and other statistical data that management believes will enhance the understanding of AFG’s financial condition, changes in financial condition and results of operations. The tables and narrative that follow are presented in a manner that is consistent with the information that AFG’s management uses to make operational decisions and allocate capital resources. They are provided to demonstrate the nature of the transactions and events that could impact AFG’s financial results. This discussion should be read in conjunction with the financial statements beginning on page 2.

OVERVIEW

Financial Condition

AFG is organized as a holding company with almost all of its operations being conducted by subsidiaries. AFG, however, has continuing cash needs for administrative expenses, the payment of principal and interest on borrowings, shareholder dividends, and taxes. Therefore, certain analyses are most meaningfully presented on a parent only basis while others are best done on a total enterprise basis. In addition, because its businesses are financial in nature, AFG does not prepare its consolidated financial statements using a current-noncurrent format. Consequently, certain traditional ratios and financial analysis tests are not meaningful.

Results of Operations

Through the operations of its subsidiaries, AFG is engaged primarily in property and casualty insurance, focusing on specialized commercial products for businesses.

AFG reported net earnings of $200 million ($2.34 per share, diluted) for the second quarter of 2023 compared to $167 million ($1.96 per share, diluted) for the second quarter of 2022. The year-over-year increase was due primarily to lower net realized losses on securities and the impact of higher yields on fixed maturity investments. These items were partially offset by lower underwriting profit and lower returns on AFG’s alternative investment portfolio (partnerships and similar investments and AFG-managed CLOs).

AFG reported net earnings of $412 million ($4.83 per share, diluted) for the first six months of 2023 compared to $457 million ($5.36 per share, diluted) for the first six months of 2022. The year-over-year decrease was due primarily to lower underwriting profit and lower returns on AFG’s alternative investment portfolio (partnerships and similar investments and AFG-managed CLOs) when compared to the strong performance of this portfolio in the prior year period. These items were partially offset by the impact of higher yields on fixed maturity investments and lower net realized losses on securities.

Outlook

AFG’s financial condition, results of operations and cash flows are impacted by the economic, legal and regulatory environment. Economic inflation, social inflation, supply chain disruption, labor shortages, banking system instability and other economic conditions may impact premium levels, loss cost trends and investment returns. Management believes that AFG’s strong financial position and current liquidity and capital at its subsidiaries will give AFG the flexibility to continue to effectively address and respond to the ongoing uncertainties presented by the macro-economic environment, the conflict between Russia and Ukraine and any lingering effects of the COVID-19 pandemic. AFG’s insurance subsidiaries continue to have capital at or in excess of the levels required by ratings agencies in order to maintain their current ratings, and the parent company does not have any near-term debt maturities.

Management expects continued premium growth and strong underwriting results in the ongoing favorable property and casualty insurance market. In addition, the deployment of cash during the elevated interest rate environment (since early 2022) will continue to have a positive impact on investment income on fixed maturity investments throughout 2023.

CRITICAL ACCOUNTING POLICIES

Significant accounting policies are summarized in Note A — “Accounting Policies” to the financial statements. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions

33

AMERICAN FINANCIAL GROUP, INC. 10-Q

Management’s Discussion and Analysis of Financial Condition and Results of Operations — Continued

that can have a significant effect on amounts reported in the financial statements. As more information becomes known, these estimates and assumptions change and, thus, impact amounts reported in the future. The areas where management believes the degree of judgment required to determine amounts recorded in the financial statements is most significant are as follows:

•the valuation of investments, including the determination of impairment allowances,

•the establishment of insurance reserves, especially asbestos and environmental-related reserves,

•the recoverability of reinsurance, and

•the establishment of asbestos and environmental liabilities of former railroad and manufacturing operations.

For a discussion of these policies, see Management’s Discussion and Analysis — “Critical Accounting Policies” in AFG’s 2022 Form 10-K.

LIQUIDITY AND CAPITAL RESOURCES

Ratios

AFG’s debt to total capital ratio on a consolidated basis is shown below (dollars in millions):

				December 31,
	June 30, 2023			2022			2021
Principal amount of long-term debt	$	1,498		$	1,521		$	1,993
Total capital	5,988			6,099			6,869
Ratio of debt to total capital:
Including subordinated debt	25.0		%	24.9		%	29.0		%
Excluding subordinated debt	13.7		%	13.9		%	19.2		%

The ratio of debt to total capital is a non-GAAP measure that management believes is useful for investors, analysts and ratings agencies to evaluate AFG’s financial strength and liquidity and to provide insight into how AFG finances its operations. In addition, maintaining a ratio of debt, excluding subordinated debt and debt secured by real estate (if any), to total capital of 35% or lower is a financial covenant in AFG’s bank credit facility. The ratio is calculated by dividing the principal amount of AFG’s long-term debt by its total capital, which includes long-term debt and shareholders’ equity (excluding unrealized gains (losses) related to fixed maturity investments).

Condensed Consolidated Cash Flows

AFG’s principal sources of cash include insurance premiums, income from its investment portfolio and proceeds from the maturities, redemptions and sales of investments. Insurance premiums in excess of acquisition expenses and operating costs are invested until they are needed to meet policyholder obligations or made available to the parent company through dividends to cover debt obligations and corporate expenses, and to provide returns to shareholders through share repurchases and dividends. Cash flows from operating, investing and financing activities as detailed in AFG’s Consolidated Statement of Cash Flows are shown below (in millions):

	Six months ended June 30,
	2023		2022
Net cash provided by operating activities	$	518	$	514
Net cash provided by (used in) investing activities	368		(501)
Net cash used in financing activities	(770)		(1,177)
Net change in cash and cash equivalents	$	116	$	(1,164)

Net Cash Provided by Operating Activities   AFG’s property and casualty insurance operations typically produce positive net operating cash flows as premiums collected and investment income exceed policy acquisition costs, claims payments and operating expenses. AFG’s net cash provided by operating activities is impacted by the level and timing of property and casualty premiums, claim and expense payments and recoveries from reinsurers. Cash flows provided by operating activities also include the activity of AFG’s managed investment entities (collateralized loan obligations (“CLO”)) other than those activities included in investing or financing activities. The changes in the assets and liabilities of the managed investment entities included in operating activities increased cash flows from operating activities by $70 million during the first six months of 2023 and $42 million in the first six months of 2022, accounting for a $28 million increase in cash flows from operating activities in the 2023 period compared to the 2022 period. As discussed in Note A —

“Accounting Policies — Managed Investment Entities” to the financial statements, AFG has no right to use the CLO assets and no obligation to pay the CLO liabilities and such assets and liabilities are shown separately in AFG’s Balance Sheet. Excluding the impact of the managed investment entities, net cash provided by operating activities was $448 million and $472 million in the first six months of 2023 and 2022, respectively.

Net Cash Provided by (Used in) Investing Activities   AFG’s investing activities consist primarily of the investment of funds provided by its property and casualty businesses. Investing activities also include the purchase and disposal of managed investment entity investments, which are presented separately in AFG’s Balance Sheet. Net investment activity in the managed investment entities was a $153 million source of cash in the first six months of 2023 compared to a $245 million use of cash in the comparable 2022 period, accounting for a $398 million increase in net cash provided by investing activities in the first six months of 2023 compared to the same 2022 period. See Note A — “Accounting Policies — Managed Investment Entities” and Note F — “Managed Investment Entities” to the financial statements. Excluding the activity of the managed investment entities, investing activities were a $215 million source of cash in the first six months of 2023 compared to a $256 million use of cash in the first six months of 2022, a change of $471 million reflecting the opportunistic investment of cash on hand in the property and casualty operations during the rising interest rate environment in the first six months of 2022.

Net Cash Used in Financing Activities   AFG’s financing activities consist primarily of issuances and retirements of long-term debt, issuances and repurchases of common stock and dividend payments. Net cash used in financing activities was $770 million for the first six months of 2023 compared to $1.18 billion in the first six months of 2022, a decrease of $407 million. AFG paid cash dividends totaling $446 million in the first six months of 2023 compared to $942 million in the first six months of 2022, a decrease in cash used by financing activities of $496 million. Debt retirements were a $21 million use of cash in the first six months of 2023 compared to $433 million in the first six months of 2022, a decrease in cash used in financing activities of $412 million. During the first six months of 2023, AFG repurchased $67 million of its Common Stock compared to $5 million in the comparable 2022 period, resulting in a $62 million increase in net cash used in financing activities in the first six months of 2023 compared to the first six months of 2022. Financing activities also include issuances and retirements of managed investment entity liabilities, which are nonrecourse to AFG and presented separately in AFG’s Balance Sheet. Retirements of managed investment entity liabilities exceeded issuances by $244 million in the first six months of 2023 compared to issuances exceeding retirements by $194 million in the first six months of 2022, accounting for a $438 million increase in net cash used in financing activities in the 2023 period compared to the 2022 period. See Note A — “Accounting Policies — Managed Investment Entities” and Note F — “Managed Investment Entities” to the financial statements.

Parent and Subsidiary Liquidity

Parent Holding Company Liquidity   Management believes AFG has sufficient resources to meet its liquidity requirements. If funds generated from operations, including dividends, tax payments and borrowings from subsidiaries, are insufficient to meet fixed charges in any period, AFG would be required to utilize parent company cash and investments or to generate cash through borrowings, sales of other assets or similar transactions.

AFG's operations continue to generate significant excess capital for returns of capital to shareholders in the form of regular and special cash dividends and through opportunistic share repurchases or to be deployed into its property and casualty businesses as management identifies the potential for profitable organic growth and opportunities to expand through acquisitions of established businesses, such as the July 2023 acquisition of CRS, and acquisitions of or investments in start-ups that meet target return thresholds.

During the first six months of 2023, AFG repurchased 574,720 shares of its Common Stock for $67 million and paid a special cash dividend of $4.00 per share in February totaling $341 million.

AFG may, at any time and from time to time, seek to retire or purchase its outstanding debt through cash purchases or exchanges for equity or debt, in open-market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will be upon such terms and at such prices as management may determine, and will depend on prevailing market conditions, AFG’s liquidity requirements, contractual restrictions and other factors. During the first six months of 2023, AFG repurchased $23 million principal amount of its senior notes for $21 million cash.

During 2022, AFG repurchased 89,368 shares of its Common Stock for $11 million and paid special cash dividends totaling $1.02 billion ($2.00 per share in March, $8.00 per share in May and $2.00 per share in November). In 2022, AFG repurchased $472 million principal amount of its senior notes for $477 million cash.

Management’s Discussion and Analysis of Financial Condition and Results of Operations — Continued

At June 30, 2023, AFG (parent) held $551 million in cash and investments. Management believes that AFG’s cash balances are held at stable banking institutions, although the amounts of many of these deposits are in excess of federally insured balances. In June 2023, AFG replaced its existing credit facility with a new five-year, $450 million revolving credit facility, which expires in June 2028. Amounts borrowed under this agreement bear interest at rates ranging from 1.00% to 1.75% (based on AFG’s credit rating, currently 1.25%) over a SOFR-based floating rate. There were no borrowings under AFG’s credit facilities, or under any other parent company short-term borrowing arrangements, during 2022 or the first six months of 2023.

Under a tax allocation agreement with AFG, all 80% (or more) owned U.S. subsidiaries generally pay taxes to (or recover taxes from) AFG based on each subsidiary’s contribution to amounts due under AFG’s consolidated tax return.

Subsidiary Liquidity   The liquidity requirements of AFG’s insurance subsidiaries relate primarily to the policyholder claims and underwriting expenses and payments of dividends and taxes to AFG. Historically, cash flows from premiums and investment income have generally provided more than sufficient funds to meet these requirements. Funds received in excess of cash requirements are generally invested in marketable securities. In addition, the insurance subsidiaries generally hold a significant amount of highly liquid, short duration investments.

AFG believes its insurance subsidiaries maintain sufficient liquidity to pay claims and underwriting expenses. In addition, these subsidiaries have sufficient capital to meet commitments in the event of unforeseen events such as reserve deficiencies, inadequate premium rates or reinsurer insolvencies. Even in the current uncertain economic environment, management believes that the capital levels in AFG’s insurance subsidiaries are adequate to maintain its business and rating agency ratings. Nonetheless, changes in statutory accounting rules, significant declines in the fair value of the insurance subsidiaries’ investment portfolios or significant ratings downgrades on these investments, could create a need for additional capital.

Investments

AFG’s investment portfolio at June 30, 2023, contained $9.89 billion in fixed maturity securities classified as available for sale and carried at fair value with unrealized gains and losses included in accumulated other comprehensive income and $38 million in fixed maturities classified as trading with holding gains and losses included in net investment income. In addition, AFG’s investment portfolio includes $618 million in equity securities carried at fair value with holding gains and losses included in realized gains (losses) on securities and $430 million in equity securities carried at fair value with holding gains and losses included in net investment income.

Fair values for AFG’s portfolio are determined by AFG’s internal investment professionals using data from nationally recognized pricing services, non-binding broker quotes and other market information. Fair values of equity securities are generally based on published closing prices. For AFG’s fixed maturity portfolio, approximately 89% was priced using pricing services at June 30, 2023 and 5% was priced using non-binding broker quotes. When prices obtained for the same security vary, AFG’s internal investment professionals select the price they believe is most indicative of an exit price.

The pricing services use a variety of observable inputs to estimate fair value of fixed maturities that do not trade on a daily basis. Based upon information provided by the pricing services, these inputs include, but are not limited to, recent reported trades, benchmark yields, issuer spreads, bids or offers, reference data, and measures of volatility. Included in the pricing of mortgage-backed securities (“MBS”) are estimates of the rate of future prepayments and defaults of principal over the remaining life of the underlying collateral. Due to the lack of transparency in the process that brokers use to develop prices, valuations that are based on brokers’ prices are classified as Level 3 in the GAAP hierarchy unless the price can be corroborated, for example, by comparison to similar securities priced using observable inputs.

Valuation techniques utilized by pricing services and prices obtained from external sources are reviewed by AFG’s internal investment professionals who are familiar with the securities being priced and the markets in which they trade to ensure the fair value determination is representative of an exit price. To validate the appropriateness of the prices obtained, these investment managers consider widely published indices (as benchmarks), recent trades, changes in interest rates, general economic conditions and the credit quality of the specific issuers. In addition, AFG communicates directly with pricing services regarding the methods and assumptions used in pricing, including verifying, on a test basis, the inputs used by the services to value specific securities.

In general, the fair value of AFG’s fixed maturity investments is inversely correlated to changes in interest rates. The following table demonstrates the sensitivity of such fair values to reasonably likely changes in interest rates by illustrating the estimated effect on AFG’s fixed maturity portfolio that an immediate increase of 100 basis points in the interest rate yield curve would have had at June 30, 2023 (dollars in millions). Effects of increases or decreases from the 100 basis points illustrated would be approximately proportional.

Fair value of fixed maturity portfolio	$	9,923
Percentage impact on fair value of 100 bps increase in interest rates	(3.0		%)
Pretax impact on fair value of fixed maturity portfolio	$	(298)

Approximately 93% of the fixed maturities held by AFG at June 30, 2023, were rated “investment grade” (credit rating of AAA to BBB) by nationally recognized rating agencies, 4% were rated “non-investment grade” and 3% were not rated. Investment grade securities generally bear lower yields and lower degrees of risk than those that are unrated and non-investment grade. Management believes that the high-quality investment portfolio should generate a stable and predictable investment return.

Municipal bonds represented approximately 10% of AFG’s fixed maturity portfolio at June 30, 2023. AFG’s municipal bond portfolio is high quality, with over 99% of the securities rated investment grade at that date. The portfolio is well diversified across the states of issuance and individual issuers. At June 30, 2023, approximately 92% of the municipal bond portfolio was held in revenue bonds, with the remaining 8% held in general obligation bonds.

AFG has less than $100 million of direct exposure to office commercial real estate through property ownership, mortgages or equity method investments. AFG’s exposure to office commercial real estate within its fixed maturity portfolio includes securities (the majority of which are AAA-rated) with a carrying value of approximately $640 million that have minimal exposure to office commercial real estate.

Summarized information for the unrealized gains and losses recorded in AFG’s Balance Sheet at June 30, 2023, is shown in the following table (dollars in millions). Approximately $208 million of available for sale fixed maturity securities had no unrealized gains or losses at June 30, 2023.

When a decline in the value of a specific investment is considered to be other-than-temporary, an allowance for credit losses (impairment) is charged to earnings (accounted for as a realized loss). The determination of whether unrealized losses are other-than-temporary requires judgment based on subjective as well as objective factors as detailed in AFG’s 2022 Form 10-K under Management’s Discussion and Analysis — “Investments.”

38

AMERICAN FINANCIAL GROUP, INC. 10-Q

Management’s Discussion and Analysis of Financial Condition and Results of Operations — Continued

Based on its analysis, management believes AFG will recover its cost basis (net of any allowance) in the fixed maturity securities with unrealized losses and that AFG has the ability to hold the securities until they recover in value and had no intent to sell them at June 30, 2023. Although AFG has the ability to continue holding its fixed maturity investments with unrealized losses, its intent to hold them may change due to deterioration in the issuers’ creditworthiness, decisions to lessen exposure to a particular issuer or industry, asset/liability management decisions, market movements, changes in views about appropriate asset allocation or the desire to offset taxable realized gains. Should AFG’s ability or intent change regarding a particular security, a charge for impairment would likely be required. While it is not possible to accurately predict if or when a specific security will become impaired, increases in the allowance for credit losses could be material to results of operations in future periods. Significant declines in the fair value of AFG’s investment portfolio could have a significant adverse effect on AFG’s liquidity. For information on AFG’s realized gains (losses) on securities, see “Results of Operations — Realized Gains (Losses) on Securities.”

Uncertainties

Management believes that the areas posing the greatest risk of material loss are the adequacy of its insurance reserves and contingencies arising out of its former railroad and manufacturing operations. See Management’s Discussion and Analysis — “Uncertainties — Asbestos and Environmental-related (“A&E”) Insurance Reserves” in AFG’s 2022 Form 10–K.

MANAGED INVESTMENT ENTITIES

Accounting standards require AFG to consolidate its investments in collateralized loan obligation (“CLO”) entities that it manages and owns an interest in (in the form of debt). See Note A — “Accounting Policies — Managed Investment Entities” and Note F — “Managed Investment Entities” to the financial statements. The effect of consolidating these entities is shown in the tables below (in millions). The “Before CLO Consolidation” columns include AFG’s investment and earnings in the CLOs on an unconsolidated basis.

RESULTS OF OPERATIONS

General

AFG’s net earnings, determined in accordance with GAAP, include certain items that may not be indicative of its ongoing core operations. Core net operating earnings excludes realized gains (losses) on securities because such gains and losses are influenced significantly by financial markets, interest rates and the timing of sales. In addition, special charges related to coverage that AFG no longer writes, such as asbestos and environmental exposures, are excluded from core earnings.

The following table (in millions, except per share amounts) identifies non-core items and reconciles net earnings to core net operating earnings, a non-GAAP financial measure. AFG believes core net operating earnings is a useful tool for investors and analysts in analyzing ongoing operating trends and for management to evaluate financial performance against historical results because it believes this provides a more comparable measure of its continuing business.

Net earnings were $200 million in the second quarter of 2023 compared to $167 million in the second quarter of 2022 reflecting lower net realized losses on securities, partially offset by lower core net operating earnings in the second quarter of 2023 compared to the second quarter of 2022. Core net operating earnings for the second quarter of 2023 decreased $41 million compared to the second quarter of 2022 reflecting lower underwriting profit and lower returns on AFG’s alternative investment portfolio, partially offset by the impact of higher yields on fixed maturity investments and lower interest charges on borrowed money. Net realized losses on securities in the second quarter of 2023 and 2022 include after-tax gains of $1 million and after-tax losses of $65 million, respectively, resulting from the change in fair value of equity securities that were still held at the balance sheet date.

AMERICAN FINANCIAL GROUP, INC. 10-Q

Management’s Discussion and Analysis of Financial Condition and Results of Operations — Continued

Net earnings were $412 million in the first six months of 2023 compared to $457 million in the first six months of 2022 reflecting lower core net operating earnings, partially offset by lower net realized losses on securities in the first six months of 2023 compared to the first six months of 2022. Core net operating earnings for the first six months of 2023 decreased $97 million compared to the first six months of 2022 reflecting lower underwriting profit and lower returns on AFG’s alternative investment portfolio when compared to the strong performance of this portfolio in the prior year period, partially offset by the impact of higher yields on fixed maturity investments and lower interest charges on borrowed money. Net realized losses on securities in the first six months of 2023 and 2022 include after-tax losses of $17 million and $75 million, respectively, resulting from the change in fair value of equity securities that were still held at the balance sheet date.

Segmented Statement of Earnings

AFG reports its operations as two segments: (i) Property and casualty insurance (“P&C”) and (ii) Other, which includes holding company costs and income and expenses related to the managed investment entities (“MIEs”).

AFG’s net earnings, determined in accordance with GAAP, include certain items that may not be indicative of its ongoing core operations. The following tables for the three months ended June 30, 2023 and 2022 identify such items by segment and reconcile net earnings to core net operating earnings, a non-GAAP financial measure that AFG believes is a useful tool for investors and analysts in analyzing ongoing operating trends (in millions):

Property and Casualty Insurance Segment — Results of Operations

Performance measures such as underwriting profit or loss and related combined ratios are often used by property and casualty insurers to help users of their financial statements better understand the company’s performance. Underwriting profitability is measured by the combined ratio, which is a sum of the ratios of losses and loss adjustment expenses, and commissions and other underwriting expenses to premiums. A combined ratio under 100% indicates an underwriting profit. The combined ratio does not reflect net investment income, other income, other expenses or federal income taxes.

AFG’s property and casualty insurance operations contributed $299 million in pretax earnings in the second quarter of 2023 compared to $345 million in the second quarter of 2022, a decrease of $46 million (13%). The decrease in pretax earnings reflects lower underwriting profit, partially offset by higher net investment income in the second quarter of 2023 compared to the second quarter of 2022.

AFG reports the underwriting performance of its Specialty property and casualty insurance business in the following sub-segments: (i) Property and transportation, (ii) Specialty casualty and (iii) Specialty financial.

To understand the overall profitability of particular lines, the timing of claims payments and the related impact of investment income must be considered. Certain “short-tail” lines of business (primarily property coverages) generally have quick loss payouts, which reduce the time funds are held, thereby limiting investment income earned thereon. In contrast, “long-tail” lines of business (primarily liability coverages and workers’ compensation) generally have payouts that are either structured over many years or take many years to settle, thereby significantly increasing investment income earned on related premiums received.

Gross written premiums for the second quarter of 2023 increased $246 million (12%) compared to the second quarter of 2022. Year-over-year premium growth was reported within each of the Specialty property and casualty sub-segments as a result of a combination of new business opportunities, increased exposures and a good renewal rate environment. Overall average renewal rates increased approximately 4% in the second quarter of 2023. Excluding overall rate decreases in the workers’ compensation businesses, renewal rates increased approximately 5%.

Property and transportation Gross written premiums increased $97 million (10%) in the second quarter of 2023 compared to the second quarter of 2022. Factors contributing to the year-over-year growth included the impact of increased rates and exposures in the transportation businesses and, to a lesser extent, the impact of earlier planting of corn and soybeans in the crop insurance business. Average renewal rates increased approximately 6% for this group in the second quarter of 2023. Reinsurance premiums ceded as a percentage of gross written premiums increased 3 percentage points in the second quarter of 2023 compared to the second quarter of 2022 reflecting growth in alternative

risk transfer products in the transportation businesses, which cede a larger percentage of premiums than some of the other businesses in the Property and transportation sub-segment.

Specialty casualty Gross written premiums increased $64 million (7%) in the second quarter of 2023 compared to the second quarter of 2022 due primarily to increased exposures and higher renewal rates in the excess and surplus business, new business opportunities, strong policy retention and rate increases in several of the targeted markets businesses, and payroll growth in the workers’ compensation businesses. This growth was partially offset by lower year-over-year premiums in the executive liability business. Average renewal rates increased approximately 3% for this group in the second quarter of 2023. Excluding overall rate decreases in the workers’ compensation businesses, renewal rates for this group increased approximately 6%. Reinsurance premiums ceded as a percentage of gross written premiums were comparable in the second quarter of 2023 and the second quarter of 2022.

Specialty financial Gross written premiums increased $85 million (40%) in the second quarter of 2023 compared to the second quarter of 2022. Growth in the financial institutions business resulted from market opportunities and the addition of several new accounts. Average renewal rates increased approximately 2% for this group in the second quarter of 2023. Reinsurance premiums ceded as a percentage of gross written premiums increased 2 percentage points in the second quarter of 2023 compared to the second quarter of 2022 reflecting higher cessions in the innovative markets business.

Other specialty The amounts shown as reinsurance premiums ceded represent business assumed by AFG’s internal reinsurance program from the operations that make up AFG’s other Specialty property and casualty insurance sub-segments. Reinsurance premiums assumed increased $5 million in the second quarter of 2023 compared to the second quarter of 2022 reflecting an increase in premiums retained, primarily from businesses in the Specialty casualty sub-segment.

The Specialty property and casualty insurance operations generated an underwriting profit of $123 million in the second quarter of 2023 compared to $197 million in the second quarter of 2022, a decrease of $74 million (38%). This decrease reflects lower underwriting profit in each of the Specialty property and casualty sub-segments. Overall catastrophe losses were $53 million (3.5 points on the combined ratio), including $2 million in net reinstatement premiums, in the second quarter of 2023 compared to catastrophe losses of $22 million (1.5 points) in the second quarter of 2022.

Property and transportation Underwriting profit for this group was $32 million for the second quarter of 2023 compared to $39 million for the second quarter of 2022, a decrease of $7 million (18%). Higher year-over-year underwriting profitability in the property and inland marine and ocean marine businesses was more than offset by lower favorable prior year reserve development in the transportation businesses. Catastrophe losses were $15 million (2.9 points on the combined ratio) in the second quarter of 2023 compared to $19 million (3.8 points) in the second quarter of 2022.

Specialty casualty Underwriting profit for this group was $95 million for the second quarter of 2023 compared to $130 million for the second quarter of 2022, a decrease of $35 million (27%). Lower levels of favorable prior year reserve development in the workers’ compensation businesses and adverse reserve development in the public sector business were partially offset by higher levels of favorable prior year reserve development in the executive liability business. Catastrophe losses were $8 million (1.0 points on the combined ratio), including $2 million in net reinstatement premiums, in the second quarter of 2023 compared to catastrophe losses of less than $1 million (0.1 points) in the second quarter of 2022.

Specialty financial Underwriting profit for this group was $10 million for the second quarter of 2023 compared to $37 million in the second quarter of 2022, a decrease of $27 million (73%). This decrease reflects higher year-over-year catastrophe losses in the financial institutions business and lower underwriting profitability in the surety and fidelity businesses. Catastrophe losses were $19 million (9.6 points on the combined ratio) compared to $3 million (1.6 points) in the second quarter of 2022.

Other specialty This group reported an underwriting loss of $14 million in the second quarter of 2023 compared to $9 million in the second quarter of 2022, an increase of $5 million (56%), reflecting higher losses in the business assumed by AFG’s internal reinsurance program from the operations that make up AFG’s other Specialty sub-segments in the second quarter of 2023 compared to the second quarter of 2022. Catastrophe losses were $11 million in the second quarter of 2023 compared to less than $1 million in the second quarter of 2022.

Aggregate Aggregate underwriting results for AFG’s property and casualty insurance segment includes favorable prior year reserve development of $1 million in the second quarter of 2023 compared to adverse prior year reserve development of $1 million in the second quarter of 2022 related to business outside of the Specialty group that AFG no longer writes.

Current accident year losses and LAE, excluding catastrophe losses

The current accident year loss and LAE ratio, excluding catastrophe losses for AFG’s Specialty property and casualty insurance operations was 60.7% for the second quarter of 2023 compared to 60.1% for the second quarter of 2022, an increase of 0.6 percentage points.

Property and transportation   The 1.2 percentage point decrease in the loss and LAE ratio for the current year, excluding catastrophe losses is due primarily to the impact of elevated large loss activity in the property and inland marine business in the second quarter of 2022 and lower current accident year losses in certain transportation businesses.

Specialty casualty   The 0.3 percentage point increase in the loss and LAE ratio for the current year, excluding catastrophe losses reflects higher claim severity in certain liability and umbrella coverages, partially offset by the impact of an improvement in the estimated 2023 accident year to date losses recorded in the second quarter of 2023 in the executive liability business.

51

AMERICAN FINANCIAL GROUP, INC. 10-Q

Management’s Discussion and Analysis of Financial Condition and Results of Operations — Continued

Specialty financial The 4.0 percentage point increase in the loss and LAE ratio for the current year, excluding catastrophe losses reflects growth in a product offered in the financial institutions business with a higher expected loss ratio compared to some of the other businesses in the Specialty financial sub-segment, and the impact of very strong results reported in the 2022 period in AFG’s European and trade credit businesses.

Net prior year reserve development

AFG’s Specialty property and casualty insurance operations recorded net favorable reserve development related to prior accident years of $61 million in the second quarter of 2023 compared to $86 million in the second quarter of 2022, a decrease of $25 million (29%).

Property and transportation Net favorable reserve development of $21 million in the second quarter of 2023 reflects lower than expected claim frequency and severity in the trucking business, lower than anticipated losses in the crop business and lower than anticipated claim frequency in the ocean marine business. Net favorable reserve development of $30 million in the second quarter of 2022 reflects lower than anticipated losses in the crop business, lower than expected claim frequency in the trucking business, lower than expected claim frequency and severity in the aviation business and lower than anticipated claim severity in the property and inland marine business.

Specialty casualty Net favorable reserve development of $24 million in the second quarter of 2023 reflects lower than anticipated claim severity in the workers’ compensation businesses, lower than expected claim frequency in the executive liability and environmental businesses and favorable reserve development related to COVID-19 losses across several businesses, partially offset by higher than anticipated claim severity in the public sector business. Net favorable reserve development of $49 million in the second quarter of 2022 reflects lower than anticipated claim severity in the workers’ compensation businesses and lower than expected claim frequency in the executive liability and excess and surplus businesses, partially offset by higher than anticipated claim severity in the excess liability businesses.

Specialty financial Net favorable reserve development of $11 million in the second quarter of 2023 reflects lower than anticipated claim frequency in the trade credit and financial institutions businesses and lower than expected claim frequency and severity in the fidelity business. Net favorable reserve development of $15 million in the second quarter of 2022 reflects lower than anticipated claim frequency in the surety and trade credit businesses and lower than expected claim frequency and severity in the fidelity business.

Other specialty In addition to the development discussed above, total Specialty prior year reserve development includes net favorable reserve development of $5 million in the second quarter of 2023 and net adverse reserve development of $8 million in the second quarter of 2022 associated with AFG’s internal reinsurance program and the amortization of the deferred gain on the retroactive reinsurance transaction entered into in connection with the sale of a business in 1998. The 2022 period reflects net adverse reserve development primarily related to social inflation exposed business assumed from the Specialty casualty sub-segment.

Aggregate Aggregate net prior accident years reserve development for AFG’s property and casualty insurance segment includes net favorable reserve development of $1 million in the second quarter of 2023 and net adverse reserve development of $1 million in the second quarter of 2022 related to business outside of the Specialty group that AFG no longer writes.

COVID-19 related losses

AFG’s Specialty property and casualty insurance operations released prior accident year COVID-19 reserves of $7 million in the second quarter of 2023 and $4 million in the second quarter of 2022 based on improved loss experience across several businesses. Given the uncertainties surrounding the ultimate number and scope of claims relating to the pandemic, approximately 42% of the $66 million in cumulative COVID-19 related losses are held as incurred but not reported reserves at June 30, 2023.

Catastrophe losses

AFG generally seeks to reduce its exposure to catastrophes (whether resulting from climate change or otherwise) through individual risk selection, including minimizing coastal and known fault-line exposures, and the purchase of reinsurance. Based on data available at December 31, 2022, AFG’s exposure to a catastrophic earthquake or windstorm that industry

models indicate should statistically occur once in every 100, 250 or 500 years as a percentage of AFG’s Shareholders’ Equity is shown below:

	Approximate impact of modeled loss
Industry Model	on AFG’s Shareholders’ Equity
100-year event	2%
250-year event	2%
500-year event	2%

AFG maintains comprehensive property catastrophe reinsurance coverage for its property and casualty insurance operations, including a $50 million per occurrence net retention, for losses up to $125 million in the vast majority of circumstances. In certain unlikely events, AFG’s ultimate loss under this coverage could be as high as $84 million for a single occurrence. AFG further maintains supplemental fully collateralized reinsurance coverage up to 95% of $323 million for catastrophe losses in excess of $127 million of traditional catastrophe reinsurance through a catastrophe bond.

Catastrophe losses of $51 million in the second quarter of 2023 and $22 million in the second quarter of 2022 resulted primarily from storms in multiple regions of the United States.

Commissions and Other Underwriting Expenses

AFG’s property and casualty commissions and other underwriting expenses (“U/W Exp”) were $478 million in the second quarter of 2023 compared to $423 million for the second quarter of 2022, an increase of $55 million (13%). AFG’s underwriting expense ratio, calculated as commissions and other underwriting expenses divided by net premiums earned, was 31.7% for the second quarter of 2023 compared to 30.4% for the second quarter of 2022, an increase of 1.3 percentage points. Detail of AFG’s property and casualty commissions and other underwriting expenses and underwriting expense ratios is shown below (dollars in millions):

Property and transportation   Commissions and other underwriting expenses as a percentage of net earned premiums increased 1.7 percentage points in the second quarter of 2023 compared to the second quarter of 2022 reflecting higher expenses related to certain technology initiatives.

Specialty casualty   Commissions and other underwriting expenses as a percentage of net earned premiums increased 1.2 percentage points in the second quarter of 2023 compared to the second quarter of 2022 reflecting higher expenses related to certain technology initiatives.

Specialty financial   Commissions and other underwriting expenses as a percentage of net earned premiums increased 1.4 percentage points in the second quarter of 2023 compared to the second quarter of 2022 reflecting higher expenses related to certain technology initiatives and higher commissions paid to agents in the surety business, partially offset by the impact of higher premiums on the ratio in the second quarter of 2023 compared to the second quarter of 2022.

Property and Casualty Net Investment Income

Net investment income in AFG’s property and casualty insurance operations was $191 million in the second quarter of 2023 compared to $156 million in the second quarter of 2022, an increase of $35 million (22%). The average invested assets and overall yield earned on investments held by AFG’s property and casualty insurance operations are provided below (dollars in millions):

	Three months ended June 30,
	2023			2022			Change			% Change
Net investment income:
Net investment income, excluding alternative investments	$	136		$	94		$	42		45	%

Tax equivalent yield (*)	5.34		%	4.56		%	0.78		%

(*)Adjusts the yield on equity securities and tax-exempt bonds to the fully taxable equivalent yield.

The increase in the property and casualty insurance segment’s net investment income for the second quarter of 2023 compared to the second quarter of 2022 reflects the impact of higher yields on fixed maturity investments and higher balances of invested assets, partially offset by lower returns on AFG’s alternative investments portfolio (partnerships and similar investments and AFG-managed CLOs). The property and casualty insurance segment’s overall yield on investments (net investment income as a percentage of average invested assets) was 5.27% for the second quarter of 2023 compared to 4.46% for the second quarter of 2022, an increase of 0.81 percentage points reflecting higher returns on fixed maturity investments, partially offset by lower yields on alternative investments. The annualized return earned on alternative investments was 9.6% in the second quarter of 2023 compared to 12.4% in the comparable prior year period.

Property and Casualty Other Income and Expenses, Net

Other income and expenses, net for AFG’s property and casualty insurance operations was a net expense of $16 million for the second quarter of 2023 compared to $7 million for the second quarter of 2022, an increase of $9 million (129%). The table below details the items included in other income and expenses, net for AFG’s property and casualty insurance operations (in millions):

The $3 million (43%) increase in interest expense on funds withheld in the second quarter of 2023 compared to the second quarter of 2022 reflects the impact of higher interest rates on funds withheld.

AFG’s net GAAP pretax loss outside of its property and casualty insurance segment (excluding realized gains and losses) totaled $42 million in the second quarter of 2023 compared to $46 million in the second quarter of 2022, a decrease of $4 million (9%). AFG’s net core pretax loss outside of its property and casualty insurance segment (excluding realized gains and losses) totaled $41 million in the second quarter of 2023 compared to $37 million in the second quarter of 2022, an increase of $4 million (11%).

The following table details AFG’s GAAP and core loss before income taxes from operations outside of its property and casualty insurance segment for the three months ended June 30, 2023 and 2022 (dollars in millions):

(*)Excludes pretax non-core losses on retirement of debt of $1 million in the second quarter of 2023 and $9 million in the second quarter of 2022.

Holding Company and Other — Net Investment Income (Loss)

AFG recorded net investment income on investments held outside of its property and casualty insurance segment of $12 million in the second quarter of 2023 compared to a net loss of less than $1 million in the second quarter of 2022. A small portfolio of equity securities held during the 2022 period at the holding company that were carried at fair value through net investment income declined in value by $7 million. Excluding the change in fair value of these equity securities, net investment income outside of AFG’s property and casualty insurance segment increased $5 million reflecting the impact of higher interest rates on cash and fixed maturity investments, partially offset by lower average balances.

Holding Company and Other — P&C Fees and Related Expenses

Summit, a workers’ compensation insurance subsidiary, collects fees from a small group of unaffiliated insurers for providing underwriting, policy administration and claims services. In addition, certain of AFG’s property and casualty insurance businesses collect fees from customers for ancillary services such as workplace safety programs and premium financing. In the second quarter of 2023, AFG collected $22 million in fees for these services compared to $18 million in the second quarter of 2022. Management views this fee income, net of the $15 million in the second quarter of 2023 and $12 million in the second quarter of 2022 in expenses incurred to generate such fees, as a reduction in the cost of underwriting its property and casualty insurance policies. In addition, AFG’s property and casualty insurance businesses collected $3 million in fees from AFG’s disposed annuity operations during the second quarter of 2022 as compensation for certain services provided under a transition services agreement. The expenses related to providing such services are embedded in property and casualty underwriting expenses. Consistent with internal management reporting, these fees and the related expenses are netted and recorded as a reduction of commissions and other underwriting expenses in AFG’s segmented results.

Holding Company and Other — Other Income

Other income in the table above includes $4 million in both the second quarter of 2023 and the second quarter of 2022, in management fees paid to AFG by the AFG-managed CLOs (AFG’s consolidated managed investment entities). The management fees are eliminated in consolidation — see the other income line in the Consolidate MIEs column under “Results of Operations — Segmented Statement of Earnings.” Excluding amounts eliminated in consolidation, AFG recorded other income outside of its property and casualty insurance segment of less than $1 million in the second quarter of 2023 and $5 million the second quarter of 2022, a decrease of $5 million, due primarily to income from the sale of real estate in the second quarter of 2022.

Holding Company and Other — Other Expenses

Excluding the non-core gain on retirement of debt discussed below, AFG’s holding companies and other operations outside of its property and casualty insurance segment recorded other expenses of $38 million in the second quarter of 2023 compared to $23 million in the second quarter of 2022, an increase of $15 million (65%), reflecting the favorable impact of poor stock market performance in the second quarter of 2022 on expenses related to deferred compensation obligations to employees that are tied to stock market performance. To mitigate the impact of fair value changes related to the equity components of these obligations, AFG entered into a total return swap in May 2022.

Holding Company and Other — Interest Charges on Borrowed Money

AFG’s holding companies and other operations outside of its property and casualty insurance segment recorded interest expense of $19 million in the second quarter of 2023 compared to $23 million in the second quarter of 2022, a decrease of $4 million (17%) reflecting the retirement of AFG’s $425 million principal amount of 3.50% Senior Notes during the first six months of 2022.

Holding Company and Other — Gain (Loss) on Retirement of Debt

During the second quarter of 2023, AFG recorded a $1 million pretax non-core loss related to the write-off of debt issue costs associated with its previous revolving credit facility, which was replaced in June 2023. During the second quarter of 2022, AFG retired its $377 million outstanding principal amount of 3.50% Senior Notes for $383 million cash (including a make-whole premium of $6 million), which resulted in a $9 million pretax non-core loss on retirement of debt.

Realized Gains (Losses) on Securities

AFG’s realized gains (losses) on securities were net losses of $2 million in the second quarter of 2023 compared to $93 million in the second quarter of 2022, a decrease of $91 million (98%). Realized gains (losses) on securities consisted of the following (in millions):

	Three months ended June 30,

Realized gains (losses) before impairment allowances:
Disposals	$	(1)	$	(7)

	(2)		(92)
Change in allowance for impairments on securities	—		(1)
Realized gains (losses) on securities	$	(2)	$	(93)

The $3 million net realized gain from the change in the fair value of equity securities in the second quarter of 2023 includes gains of $3 million on investments in capital goods companies, $2 million on investments in banks and financing companies, $2 million on investments in healthcare companies and $2 million on investments real estate investment trusts, partially offset by losses of $5 million on investments in media companies and $3 million on investments in retail companies. The $82 million net realized loss from the change in the fair value of equity securities in the second quarter of 2022 includes losses of $27 million on investments in banks and financing companies, $19 million on investments in media companies, $9 million on investments in retail companies and $8 million on investments in healthcare companies.

Segmented Statement of Earnings

AFG reports its operations as two segments: (i) Property and casualty insurance (“P&C”) and (ii) Other, which includes holding company costs and income and expenses related to the managed investment entities (“MIEs”).

AFG’s net earnings, determined in accordance with GAAP, include certain items that may not be indicative of its ongoing core operations. The following tables for the six months ended June 30, 2023 and 2022 identify such items by segment and reconcile net earnings to core net operating earnings, a non-GAAP financial measure that AFG believes is a useful tool for investors and analysts in analyzing ongoing operating trends (in millions):

Property and Casualty Insurance Segment — Results of Operations

AFG’s property and casualty insurance operations contributed $649 million in pretax earnings in the first six months of 2023 compared to $767 million in the first six months of 2022, a decrease of $118 million (15%). The decrease in pretax earnings reflects lower underwriting profit, partially offset by higher net investment income in the first six months of 2023 compared to the first six months of 2022.

Gross written premiums for the first six months of 2023 increased $465 million (11%) compared to the first six months of 2022. Year-over-year premium growth was reported within each of the Specialty property and casualty sub-segments as a result of a combination of new business opportunities, increased exposures and a good renewal rate environment. Overall average renewal rates increased approximately 4% in the first six months of 2023. Excluding the workers’ compensation businesses, renewal pricing increased approximately 5%.

Property and transportation Gross written premiums increased $209 million (12%) in the first six months of 2023 compared to the first six months of 2022. Factors contributing to the year-over-year growth included the impact of increased rates and exposures in the transportation businesses, new business opportunities in the crop insurance operations and to a lesser extent, the impact of earlier planting of corn and soybeans in the crop insurance business. Average renewal rates increased approximately 6% for this group in the first six months of 2023. Reinsurance premiums ceded as a percentage of gross written premiums increased 3 percentage points in the first six months of 2023 compared to the first six months of 2022 reflecting growth in alternative risk transfer products in the transportation businesses, which cede a larger percentage of premiums than some of the other businesses in the Property and transportation sub-segment.

Specialty casualty Gross written premiums increased $149 million (8%) in the first six months of 2023 compared to the first six months of 2022 due primarily to increased exposures and higher renewal rates in the excess and surplus business, new business opportunities, strong policy retention and rate increases in several of the targeted markets businesses, and increased exposures from payroll growth and new business in the workers’ compensation businesses. This growth was partially offset by lower premiums in the mergers and acquisitions liability and executive liability businesses. Average renewal rates increased approximately 3% for this group in the first six months of 2023. Excluding overall rate decreases in the workers’ compensation businesses, renewal rates for this group increased approximately 5%. Reinsurance premiums ceded as a percentage of gross written premiums decreased 1 percentage point in the first six months of 2023 compared to the first six months of 2022 reflecting growth in the workers’ compensation businesses, which cede a lower percentage of premiums than some of the other businesses in the Specialty casualty sub-segment, and lower cessions in the environmental and mergers and acquisition businesses and at ABA Insurance Services.

Specialty financial Gross written premiums increased $107 million (26%) in the first six months of 2023 compared to the first six months of 2022 due primarily to growth in the financial institutions, surety and commercial equipment leasing businesses. Average renewal rates increased approximately 2% for this group in the first six months of 2023. Reinsurance premiums ceded as a percentage of gross written premiums were comparable for the first six months of 2023 and the first six months of 2022.

Other specialty The amounts shown as reinsurance premiums ceded represent business assumed by AFG’s internal reinsurance program from the operations that make up AFG’s other Specialty property and casualty insurance sub-segments. Reinsurance premiums assumed increased $8 million (7%) in the first six months of 2023 compared to the first six months of 2022, reflecting an increase in premiums retained, primarily from businesses in the Specialty casualty sub-segment.

The Specialty property and casualty insurance operations generated an underwriting profit of $278 million for the first six months of 2023 compared to $405 million for the first six months of 2022, a decrease of $127 million (31%). This decrease reflects lower underwriting profit in each of the Specialty property and casualty sub-segments. Overall catastrophe losses were $84 million (2.7 points on the combined ratio), including $2 million in net reinstatement premiums, in the first six months of 2023 compared to catastrophe losses of $31 million (1.2 points) in the first six months of 2022.

Property and transportation Underwriting profit for this group was $75 million for the first six months of 2023 compared to $101 million for the first six months of 2022, a decrease of $26 million (26%), reflecting lower profitability in the property and inland marine business, which was primarily the result of elevated catastrophe losses in the 2023 period, and lower underwriting profit in the crop insurance business. Catastrophe losses were $34 million (3.3 points on the combined ratio) in the first six months of 2023 compared to $25 million (2.7 points) in the first six months of 2022.

Specialty casualty Underwriting profit for this group was $183 million for the first six months of 2023 compared to $254 million for the first six months of 2022, a decrease of $71 million (28%). The lower year-over-year underwriting profit was due primarily to lower favorable prior year reserve development in the workers’ compensation businesses and higher adverse reserve development in the public sector business, partially offset by favorable prior year reserve development in the social services, environmental and executive liability businesses. Catastrophe losses were $11 million (0.7 points on the combined ratio), including $2 million in net reinstatement premiums, in the first six months of 2023 compared to catastrophe losses of $1 million in the first six months of 2022.

Specialty financial Underwriting profit for this group was $36 million for the first six months of 2023 compared to $66 million for the first six months of 2022, a decrease of $30 million (45%). This decrease reflects higher year-over-year

Catastrophe losses were $23 million (5.8 points on the combined ratio) in the first six months of 2023 compared to $5 million (1.4 points) in the first six months of 2022.

Other specialty This group reported an underwriting loss of $16 million in both the first six months of 2023 and the first six months of 2022, reflecting losses in the business assumed by AFG’s internal reinsurance program from the operations that make up AFG’s other Specialty sub-segments. Catastrophe losses were $16 million in the first six months of 2023 compared to less than $1 million in the first six months of 2022.

Current accident year losses and LAE, excluding catastrophe losses

The current accident year loss and LAE ratio, excluding catastrophe losses for AFG’s Specialty property and casualty insurance operations was 60.1% for the first six months of 2023 compared to 59.6% for the first six months of 2022, an increase of 0.5 percentage points.

Property and transportation   The 0.2 percentage point decrease in the loss and LAE ratio for the current year, excluding catastrophe losses reflects is due primarily to the impact of elevated large loss activity in the property and inland marine business in the first six months of 2022 and lower current accident year losses in certain transportation businesses.

Specialty casualty   The 0.7 percentage point increase in the loss and LAE ratio for the current year, excluding catastrophe losses reflects higher claim severity in certain liability and umbrella coverages and an increase in the loss and LAE ratios of certain alternative markets businesses.

Specialty financial   The 1.6 percentage point increase in the loss and LAE ratio for the current year, excluding catastrophe losses reflects growth in a product offered in the financial institutions business with a higher expected loss ratio compared to some of the other businesses in the Specialty financial sub-segment, and the impact of very strong results reported in the 2022 period in AFG’s European and trade credit businesses. These increases were partially offset by a decrease in the loss and LAE ratio of the fidelity business.

Net prior year reserve development

AFG’s Specialty property and casualty insurance operations recorded net favorable reserve development related to prior accident years of $125 million in the first six months of 2023 compared to $175 million in the first six months of 2022, a decrease of $50 million (29%).

Property and transportation Net favorable reserve development of $58 million in the first six months of 2023 reflects lower than anticipated losses in the crop business, lower than expected claim frequency and severity in the trucking business and lower than anticipated claim frequency in the property and inland marine business. Net favorable reserve development of $64 million in the first six months of 2022 reflects lower than anticipated losses in the crop business, lower than expected claim frequency in the trucking and ocean marine businesses and at the Singapore branch, lower than expected claim frequency and severity in the aviation business and lower than anticipated claim severity in the property and inland marine business.

Specialty casualty Net favorable reserve development of $51 million in the first six months of 2023 reflects lower than anticipated claim severity in the workers’ compensation businesses, lower than expected claim frequency in the executive liability and environmental businesses and favorable reserve development related to COVID-19 losses across several businesses, partially offset by higher than anticipated claim severity in the public sector and excess liability businesses. Net favorable reserve development of $98 million in the first six months of 2022 reflects lower than anticipated claim severity in the workers’ compensation businesses, lower than expected claim frequency in the executive liability business and lower than anticipated claim frequency and severity in the excess and surplus business, partially offset by higher than anticipated claim severity in the targeted markets and excess liability businesses.

Specialty financial Net favorable reserve development of $14 million in the first six months of 2023 reflects lower than anticipated claim frequency in the trade credit and financial institutions businesses and lower than expected claim frequency and severity in the surety business. Net favorable reserve development of $28 million in the first six months of 2022 reflects lower than anticipated claim frequency in the surety, trade credit and financial institutions businesses.

Other specialty In addition to the development discussed above, total Specialty prior year reserve development includes net favorable reserve development of $2 million in the first six months of 2023 and net adverse reserve development of $15 million in the first six months of 2022 associated with AFG’s internal reinsurance program and the amortization of the deferred gain on the retroactive reinsurance transaction entered into in connection with the sale of a business in 1998. The 2022 period reflects net adverse reserve development primarily related to social inflation exposed business assumed from the Specialty casualty sub-segment.

Aggregate Aggregate net prior accident years reserve development for AFG’s property and casualty insurance segment includes net adverse reserve development of $2 million in the first six months of 2022 related to business outside the Specialty group that AFG no longer writes.

COVID-19 related losses

AFG’s Specialty property and casualty insurance operations released prior accident year COVID-19 reserves of $8 million in the first six months of 2023 and $6 million in the first six months of 2022 based on improved loss experience across several businesses. Given the uncertainties surrounding the ultimate number and scope of claims relating to the pandemic, approximately 42% of the $66 million in cumulative COVID-19 related losses are held as incurred but not reported reserves at June 30, 2023.

Catastrophe losses

Catastrophe losses of $82 million in the first six months of 2023 and $31 million in the first six months of 2022 resulted primarily from storms in multiple regions of the United States.

Commissions and Other Underwriting Expenses

AFG’s property and casualty commissions and other underwriting expenses (“U/W Exp”) were $941 million in the first six months of 2023 compared to $825 million for the first six months of 2022, an increase of $116 million (14%). AFG’s underwriting expense ratio was 32.0% for the first six months of 2023 compared to 30.6% for the first six months of 2022, an increase of 1.4 percentage points. Detail of AFG’s property and casualty commissions and other underwriting expenses and underwriting expense ratios is shown below (dollars in millions):

	Six months ended June 30,

Property and transportation   Commissions and other underwriting expenses as a percentage of net earned premiums increased 1.8 percentage points in the first six months of 2023 compared to the first six months of 2022 reflecting higher expenses related to certain technology initiatives.

Specialty casualty   Commissions and other underwriting expenses as a percentage of net earned premiums increased 1.4 percentage points in the first six months of 2023 compared to the first six months of 2022 reflecting higher expenses related to certain technology initiatives.

Specialty financial   Commissions and other underwriting expenses as a percentage of net earned premiums decreased 0.3 percentage points in the first six months of 2023 compared to the first six months of 2022 reflecting the impact of higher premiums on the ratio, partially offset by higher expenses related to certain technology initiatives and higher commissions paid to agents in the surety business in the first six months of 2023 compared to the first six months of 2022.

Property and Casualty Net Investment Income

Net investment income in AFG’s property and casualty insurance operations was $398 million in the first six months of 2023 compared to $379 million in the first six months of 2022, an increase of $19 million (5%). The average invested assets and overall yield earned on investments held by AFG’s property and casualty insurance operations are provided below (dollars in millions):

Tax equivalent yield (*)	5.58		%	5.56		%	0.02		%

(*)Adjusts the yield on equity securities and tax-exempt bonds to the fully taxable equivalent yield.

The increase in the property and casualty insurance segment’s net investment income for the first six months of 2023 compared to the first six months of 2022 reflects the impact of higher yields on fixed maturity investments and higher balances of invested assets, partially offset by lower returns on AFG’s alternative investments portfolio (partnerships and similar investments and AFG-managed CLOs) as compared to the very strong performance of this portfolio in the prior year period. The property and casualty insurance segment’s overall yield on investments (net investment income as a percentage of average invested assets) was 5.51% for the first six months of 2023 compared to 5.46% for the first six months of 2022, an increase of 0.05 percentage points reflecting higher returns on fixed maturity investments, partially offset by lower yields on alternative investments. The annualized return earned on alternative investments (partnerships and similar investments and AFG-managed CLOs) was 11.8% in the first six months of 2023 compared to 20.7% in the prior year period.

Property and Casualty Other Income and Expenses, Net

Other income and expenses, net for AFG’s property and casualty insurance operations was a net expense of $27 million for the first six months of 2023 compared to $15 million for the first six months of 2022, an increase of $12 million (80%). The table below details the items included in other income and expenses, net for AFG’s property and casualty insurance operations (in millions):

Holding Company and Other — Net Investment Income

AFG recorded net investment income on investments held outside of its property and casualty insurance segment of $23 million in the first six months of 2023 compared to $5 million in the first six months of 2022, an increase of $18 million (360%). A small portfolio of equity securities held during the 2022 period at the holding company that were carried at fair value through net investment income declined in value by $8 million. Excluding the change in fair value of these equity securities, net investment income outside of AFG’s property and casualty insurance segment increased $10 million reflecting the impact of higher interest rates on cash and fixed maturity investments, partially offset by lower average balances.

Holding Company and Other — P&C Fees and Related Expenses

Summit, a workers’ compensation insurance subsidiary, collects fees from a small group of unaffiliated insurers for providing underwriting, policy administration and claims services. In addition, certain of AFG’s property and casualty insurance businesses collect fees from customers for ancillary services such as workplace safety programs and premium financing. In the first six months of 2023, AFG collected $46 million in fees for these services compared to $40 million in the first six months of 2022. Management views this fee income, net of the $29 million in the first six months of 2023 and $24 million in the first six months of 2022 in expenses incurred to generate such fees, as a reduction in the cost of underwriting its property and casualty insurance policies. In addition, AFG’s property and casualty insurance businesses collected $5 million in fees from AFG’s disposed annuity operations in the first six months of 2022 as compensation for certain services provided under a transition services agreement. The expenses related to providing such services are embedded in property and casualty underwriting expenses. Consistent with internal management reporting, these fees and the related expenses are netted and recorded as a reduction of commissions and other underwriting expenses in AFG’s segmented results.

Holding Company and Other — Other Income

Other income in the table above includes $8 million in both the first six months of 2023 and the first six months of 2022, in management fees paid to AFG by the AFG-managed CLOs (AFG’s consolidated managed investment entities). The management fees are eliminated in consolidation — see the other income line in the Consolidate MIEs column under “Results of Operations — Segmented Statement of Earnings.” Excluding amounts eliminated in consolidation, AFG recorded other income outside of its property and casualty insurance segment of $3 million in the first six months of 2023 compared to $7 million in the first six months of 2022, a decrease of $4 million (57%) due primarily to income from the sale of real estate in 2022.

Holding Company and Other — Other Expenses

Excluding the non-core gain (loss) on retirement of debt discussed below, AFG’s holding companies and other operations outside of its property and casualty insurance segment recorded other expenses of $79 million in the first six months of 2023 compared to $55 million the first six months of 2022, an increase of $24 million (44%) reflecting the favorable impact of poor stock market performance in the first six months of 2022 on expenses related to deferred compensation obligations to employees that are tied to stock market performance. To mitigate the impact of fair value changes related to the equity components of these obligations, AFG entered into a total return swap in May 2022.

Holding Company and Other — Interest Charges on Borrowed Money

AFG’s holding companies and other operations outside of its property and casualty insurance segment recorded interest expense of $38 million in the first six months of 2023 compared to $46 million in the first six months of 2022, a decrease of $8 million (17%) reflecting the retirement of AFG’s $425 million principal amount of 3.50% Senior Notes during the first six months of 2022.

Holding Company and Other — Gain (Loss) on Retirement of Debt

During the first six months of 2023, AFG repurchased $23 million principal amount of its senior notes, which resulted in a $2 million pretax non-core gain and recorded a $1 million pretax non-core loss related to the write-off of debt issue costs associated with its previous revolving credit facility, which was replaced in June 2023. During the first six months of 2022, AFG retired its $425 million principal amount of 3.50% Senior Notes for $433 million cash (including a make-whole premium of $6 million), which resulted in an $11 million pretax non-core loss.

Realized Gains (Losses) on Securities

AFG’s realized gains (losses) on securities were net losses of $48 million in the first six months of 2023 compared to $108 million in the first six months of 2022, a decrease of $60 million (56%). Realized gains (losses) on securities consisted of the following (in millions):

	Six months ended June 30,
	2023		2022
Realized gains (losses) before impairment allowances:
Disposals	$	(25)	$	(6)
Change in the fair value of equity securities	(15)		(95)

	(43)		(109)
Change in allowance for impairments on securities	(5)		1
Realized gains (losses) on securities	$	(48)	$	(108)

The $25 million net realized loss from disposals in the first six months of 2023 includes losses of $15 million from the sale of investments in banks and $4 million from the sale of municipal housing bonds.

Management’s Discussion and Analysis of Financial Condition and Results of Operations — Continued

Consolidated Income Taxes

AFG’s consolidated provision for income taxes was $107 million for the first six months of 2023 compared to $110 million for the first six months of 2022, a decrease of $3 million (3%). See Note J — “Income Taxes” to the financial statements for an analysis of items affecting AFG’s effective tax rate.

ITEM 3. Quantitative and Qualitative Disclosure about Market Risk

As of June 30, 2023, there were no material changes to the information provided in Item 7A — Quantitative and Qualitative Disclosures about Market Risk of AFG’s 2022 Form 10-K.

Consistent with the discussion in Item 2 — Management’s Discussion and Analysis — “Investments,” the following table demonstrates the sensitivity of the fair value of AFG’s fixed maturity portfolio to reasonably likely changes in interest rates by illustrating the estimated effect on AFG’s fixed maturity portfolio that an immediate increase of 100 basis points in the interest rate yield curve would have at June 30, 2023 (based on the duration of the portfolio, dollars in millions). Effects of increases or decreases from the 100 basis points illustrated would be approximately proportional.

Fair value of fixed maturity portfolio	$	9,923
Percentage impact on fair value of 100 bps increase in interest rates	(3.0		%)
Pretax impact on fair value of fixed maturity portfolio	$	(298)

ITEM 4. Controls and Procedures

AFG’s management, with participation of its Co-Chief Executive Officers and its Chief Financial Officer, has evaluated AFG’s disclosure controls and procedures (as defined in Exchange Act Rule 13a-15) as of the end of the period covered by this report. Based on that evaluation, AFG’s Co-CEOs and CFO concluded that the controls and procedures are effective. There have been no changes in AFG’s internal control over financial reporting during the second fiscal quarter of 2023 that materially affected, or are reasonably likely to materially affect, AFG’s internal control over financial reporting.

In the ordinary course of business, AFG and its subsidiaries routinely enhance their information systems by either upgrading current systems or implementing new systems. There have been no changes in AFG’s business processes and procedures during the second fiscal quarter of 2023 that have materially affected, or are reasonably likely to materially affect, AFG’s internal control over financial reporting.

Accounting Policies [Abstract]

Accounting Policies

Accounting Policies

Basis of Presentation   The accompanying consolidated financial statements for American Financial Group, Inc. and its subsidiaries (“AFG”) are unaudited; however, management believes that all adjustments (consisting only of normal recurring accruals unless otherwise disclosed herein) necessary for fair presentation have been made. The results of operations for interim periods are not necessarily indicative of results to be expected for the year. The financial statements have been prepared in accordance with the instructions to Form 10-Q and, therefore, do not include all information and footnotes necessary to be in conformity with U.S. generally accepted accounting principles (“GAAP”).

Certain reclassifications have been made to prior periods to conform to the current year’s presentation. All significant intercompany balances and transactions have been eliminated. The results of operations of companies since their formation or acquisition are included in the consolidated financial statements. Events or transactions occurring subsequent to June 30, 2023, and prior to the filing of this Form 10-Q, have been evaluated for potential recognition or disclosure herein.

The preparation of the financial statements requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Changes in circumstances could cause actual results to differ materially from those estimates.

Fair Value Measurements   Accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants on the measurement date. The standards establish a hierarchy of valuation techniques based on whether the assumptions that market participants would use in pricing the asset or liability (“inputs”) are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect AFG’s assumptions about the assumptions market participants would use in pricing the asset or liability. AFG did not have any material nonrecurring fair value measurements in the first six months of 2023.

Investments   Equity securities other than those accounted for under the equity method are reported at fair value with holding gains and losses generally recorded in realized gains (losses) on securities. However, AFG records holding gains and losses on limited partnerships and similar investments that do not qualify for equity method accounting (and are therefore carried at fair value), and certain other securities classified at purchase as “fair value through net investment income” in net investment income.

Fixed maturity securities classified as “available for sale” are reported at fair value with unrealized gains and losses included in accumulated other comprehensive income (“AOCI”) in AFG’s Balance Sheet. Fixed maturity securities classified as “trading” are reported at fair value with changes in unrealized holding gains or losses during the period included in net investment income. Mortgage loans (net of any allowance) are carried primarily at the aggregate unpaid balance.

Realized gains or losses on the disposal of fixed maturity securities are determined on the specific identification basis. Premiums and discounts on fixed maturity securities are amortized using the effective interest method. Mortgage-backed securities (“MBS”) are amortized over a period based on estimated future principal payments, including prepayments. Prepayment assumptions are reviewed periodically and adjusted to reflect actual prepayments and changes in expectations.

Limited partnerships and similar investments are generally accounted for using the equity method of accounting. Under the equity method, AFG records its share of the earnings or losses of the investee based on when it is reported by the investee in its financial statements rather than in the period in which the investee declares a dividend. AFG’s share of the earnings or losses from equity method investments is generally recorded on a quarter lag due to the timing of the receipt of the investee’s financial statements. AFG’s equity in the earnings (losses) of limited partnerships and similar investments is included in net investment income.

Credit Losses on Fixed Maturity Investments   When a decline in the value of an available for sale fixed maturity is considered to be other-than-temporary at the balance sheet date, an allowance for credit losses (impairment), including any write-off of accrued interest, is charged to earnings (included in realized gains (losses) on securities). If management can assert that it does not intend to sell the security and it is not more likely than not that it will have to sell it before recovery of its amortized cost basis (net of allowance), then the impairment is separated into two components: (i) the allowance related to credit losses (recorded in earnings) and (ii) the amount related to all other factors (recorded in other comprehensive income). The credit-related portion is measured by comparing a security’s amortized cost to the present value of its current expected cash flows discounted at its effective yield prior to the charge. The allowance is limited to the difference between a security’s amortized cost basis and its fair value. Subsequent increases or decreases in expected credit losses are recorded immediately in net earnings through realized gains (losses). If management intends to sell an impaired security, or it is more likely than not that it will be required to sell the security before recovery, an impairment is recorded in earnings to reduce the amortized cost (net of allowance) of that security to fair value.

Credit Losses on Financial Instruments Measured at Amortized Cost   Credit-related impairments for financial instruments measured at amortized cost (mortgage loans, premiums receivable and reinsurance recoverables) reflect estimated credit losses expected over the life of an exposure or pool of exposures. The estimate of expected credit losses considers historical information, current information, as well as reasonable and supportable forecasts, including estimates of prepayments. Expected credit losses, and subsequent increases or decreases in such expected losses, are recorded immediately through net earnings as an allowance that is deducted from the amortized cost basis of the financial asset, with the net carrying value of the financial asset presented on the balance sheet at the amount expected to be collected.

Derivatives   Derivatives included in AFG’s Balance Sheet are recorded at fair value. Changes in fair value of derivatives are included in earnings unless the derivatives are designated and qualify as highly effective cash flow hedges. AFG’s derivatives that do not qualify for hedge accounting under GAAP consist primarily of components of certain fixed maturity securities (convertible fixed maturities and interest-only and principal-only MBS) and a total return swap related to its deferred compensation obligations to employees.

To qualify for hedge accounting, at the inception of a derivative contract, AFG formally documents the relationship between the terms of the hedge and the hedged items and its risk management objective. This documentation includes defining how hedge effectiveness is evaluated at the inception date and over the life of the derivative.

Changes in the fair value of derivatives that are designated and qualify as highly effective cash flow hedges are recorded in AOCI and are reclassified into earnings when the variability of the cash flows from the hedged items impacts earnings. When the change in the fair value of a qualifying cash flow hedge is included in earnings, it is included in the same line item in the statement of earnings as the cash flows from the hedged item. AFG uses interest rate swaps that are designated and qualify as highly effective cash flow hedges to mitigate interest rate risk related to certain floating-rate securities.

Goodwill   Goodwill represents the excess of cost of subsidiaries over AFG’s equity in their underlying net assets at the date of acquisition. Goodwill is not amortized, but is subject to an impairment test at least annually. An entity is not required to complete the quantitative annual goodwill impairment test on a reporting unit if the entity elects to perform a qualitative analysis and determines that it is more likely than not that the reporting unit’s fair value exceeds its carrying amount.

Reinsurance   Amounts recoverable from reinsurers are estimated in a manner consistent with the claim liability associated with the reinsured policies. AFG reports as assets (i) the estimated reinsurance recoverable on paid and unpaid losses, including an estimate for losses incurred but not reported, and (ii) amounts paid or due to reinsurers applicable to the unexpired terms of policies in force. Payable to reinsurers includes ceded premiums due to reinsurers, as well as ceded premiums retained by AFG under contracts to fund ceded losses as they become due. AFG also assumes reinsurance from other companies. Earnings on reinsurance assumed is recognized based on information received from ceding companies.

Deferred Policy Acquisition Costs (“DPAC”)   Policy acquisition costs (principally commissions, premium taxes and certain underwriting and policy issuance costs) directly related to the successful acquisition or renewal of an insurance contract are deferred. DPAC is limited based upon recoverability without any consideration for anticipated investment income and is charged against income ratably over the terms of the related policies. A premium deficiency is recognized if the sum of expected claims costs, claims adjustment expenses and unamortized acquisition costs exceed the related unearned premiums. A premium deficiency is first recognized by charging any unamortized acquisition costs to expense to the extent required to eliminate the deficiency. If the premium deficiency is greater than unamortized acquisition costs, a liability is accrued for the excess deficiency and reported with unpaid losses and loss adjustment expenses.

Managed Investment Entities   A company is considered the primary beneficiary of, and therefore must consolidate, a variable interest entity (“VIE”) based primarily on its ability to direct the activities of the VIE that most significantly impact that entity’s economic performance and the obligation to absorb losses of, or receive benefits from, the entity that could potentially be significant to the VIE.

AFG manages, and has investments in, collateralized loan obligations (“CLOs”) that are VIEs (see Note F — “Managed Investment Entities”). AFG has determined that it is the primary beneficiary of these CLOs because (i) its role as asset manager gives it the power to direct the activities that most significantly impact the economic performance of the CLOs and (ii) through its investment in the CLO debt tranches, it has exposure to CLO losses (limited to the amount AFG invested) and the right to receive CLO benefits that could potentially be significant to the CLOs.

Because AFG has no right to use the CLO assets and no obligation to pay the CLO liabilities, the assets and liabilities of the CLOs are shown separately in AFG’s Balance Sheet. AFG has elected the fair value option for reporting on the CLO assets and liabilities to improve the transparency of financial reporting related to the CLOs. The net gain or loss from accounting for the CLO assets and liabilities at fair value is presented separately in AFG’s Statement of Earnings.

The fair values of a CLO’s assets may differ from the separately measured fair values of its liabilities even though the CLO liabilities only have recourse to the CLO assets. AFG has set the carrying value of the CLO liabilities equal to the fair value of the CLO assets (which have more observable fair values) as an alternative to reporting those liabilities at a separately measured fair value. CLO earnings attributable to AFG’s shareholders are measured by the change in the fair value of AFG’s investments in the CLOs and management fees earned.

At June 30, 2023, assets and liabilities of managed investment entities included $105 million in assets and $86 million in liabilities of a temporary warehousing entity that was established to provide AFG the ability to form a new CLO. At closing, all warehoused assets will be transferred to the new CLO and the liabilities will be repaid.

Unpaid Losses and Loss Adjustment Expenses   The net liabilities stated for unpaid claims and for expenses of investigation and adjustment of unpaid claims represent management’s best estimate and are based upon (i) the accumulation of case estimates for losses reported prior to the close of the accounting period on direct business written; (ii) estimates received from ceding reinsurers and insurance pools and associations; (iii) estimates of unreported losses (including possible development on known claims) based on past experience; (iv) estimates based on experience of expenses for investigating and adjusting claims; and (v) the current state of the law and coverage litigation. Establishing reserves for asbestos, environmental and other mass tort claims involves considerably more judgment than other types of claims due to, among other things, inconsistent court decisions, an increase in bankruptcy filings as a result of asbestos-related liabilities, novel theories of coverage, and judicial interpretations that often expand theories of recovery and broaden the scope of coverage.

Loss reserve liabilities are subject to the impact of changes in claim amounts and frequency and other factors. Changes in estimates of the liabilities for losses and loss adjustment expenses are reflected in the statement of earnings in the period in which determined. Despite the variability inherent in such estimates, management believes that the liabilities for unpaid losses and loss adjustment expenses are adequate and reasonable.

Debt Issuance Costs   Debt issuance costs related to AFG’s outstanding debt are presented in its Balance Sheet as a direct reduction in the carrying value of long-term debt and are amortized over the life of the related debt using the effective interest method as a component of interest expense. Debt issuance costs related to AFG’s revolving credit facilities are included in other assets in AFG’s Balance Sheet.

Leases   Leases for terms of longer than one year are recognized as assets and liabilities for the rights and obligations created by those leases on the balance sheet based on the present value of contractual cash flows.

At June 30, 2023 AFG has a $190 million lease liability included in other liabilities and a lease right-of-use asset of $167 million included in other assets compared to $116 million and $103 million, respectively, at December 31, 2022. The increase in the lease liability and right-of-use asset is due primarily to the renewal of AFG’s largest office lease which extended the term for an additional 10 years.

Premium Recognition   Property and casualty premiums are earned generally over the terms of the policies on a pro rata basis. Unearned premiums represent that portion of premiums written, which is applicable to the unexpired terms of policies in force. On reinsurance assumed from other insurance companies or written through various underwriting organizations, unearned premiums are based on information received from such companies and organizations.

Income Taxes   Deferred income taxes are calculated using the liability method. Under this method, deferred income tax assets and liabilities are determined based on differences between financial reporting and tax bases and are measured using enacted tax rates. A valuation allowance is established to reduce total deferred tax assets to an amount that will more likely than not be realized. The effect of a change in tax rates on deferred tax assets and liabilities is recorded in net earnings in the period that includes the enactment date.

AFG recognizes the tax benefits of uncertain tax positions only when the position is more likely than not to be sustained under examination by the appropriate taxing authority. Interest and penalties on AFG’s reserve for uncertain tax positions are recognized as a component of tax expense.

Stock-Based Compensation   All share-based grants are recognized as compensation expense on a straight-line basis over their vesting periods based on their calculated fair value at the date of grant.

AFG records excess tax benefits or deficiencies for share-based payments through income tax expense in the statement of earnings. In addition, AFG accounts for forfeitures of awards when they occur.

Benefit Plans   AFG provides retirement benefits to qualified employees of participating companies through the AFG 401(k) Retirement and Savings Plan, a defined contribution plan. AFG makes all contributions to the retirement fund portion of the plan and matches a percentage of employee contributions to the savings fund. Company contributions are expensed in the year for which they are declared. AFG and many of its subsidiaries provide health care and life insurance benefits to eligible retirees. AFG also provides postemployment benefits to former or inactive employees (primarily those on disability) who were not deemed retired under other company plans. The projected future cost of providing these benefits is expensed over the period employees earn such benefits.

Earnings Per Share   Although basic earnings per share only considers shares of common stock outstanding during the period, the calculation of diluted earnings per share includes the following adjustments to weighted average common shares related to stock-based compensation plans: second quarter 2023 and 2022 — 0.1 million and 0.2 million; first six months of 2023 and 2022 — 0.1 million and 0.6 million.

There were no anti-dilutive potential common shares for the second quarter or the first six months of 2023 or 2022.

Statement of Cash Flows   For cash flow purposes, “investing activities” are defined as making and collecting loans and acquiring and disposing of debt or equity instruments, property and equipment and businesses. “Financing activities” include obtaining resources from owners and providing them with a return on their investments, borrowing money and repaying amounts borrowed. All other activities are considered “operating.” Short-term investments having original maturities of three months or less when purchased are considered to be cash equivalents for purposes of the financial statements.

Segment Reporting [Abstract]

Segments of Operations

Segments of Operations

AFG manages its business as two segments: Property and casualty insurance and Other, which includes holding company costs and operations attributable to the noncontrolling interests of the managed investment entities.

AFG reports its property and casualty insurance business in the following Specialty sub-segments: (i) Property and transportation, which includes physical damage and liability coverage for buses and trucks and other specialty

transportation niches, inland and ocean marine, agricultural-related products and other commercial property coverages, (ii) Specialty casualty, which includes primarily excess and surplus, executive and professional liability, general liability, umbrella and excess liability, specialty coverages in targeted markets, customized programs for small to mid-sized businesses and workers’ compensation insurance, and (iii) Specialty financial, which includes risk management insurance programs for lending and leasing institutions (including equipment leasing and collateral and lender-placed mortgage property insurance), fidelity and surety products and trade credit insurance. Premiums and underwriting profit included under Other specialty represent business assumed by AFG’s internal reinsurance program from the operations that make up AFG’s other Specialty sub-segments and amortization of a deferred gain on a retroactive reinsurance transaction related to the sale of a business. AFG’s reportable segments and their components were determined based primarily upon similar economic characteristics, products and services.

The following tables (in millions) show AFG’s revenues and earnings before income taxes by segment and sub-segment.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

Accounting standards for measuring fair value are based on inputs used in estimating fair value. The three levels of the hierarchy are as follows:

Level 1 — Quoted prices for identical assets or liabilities in active markets (markets in which transactions occur with sufficient frequency and volume to provide pricing information on an ongoing basis). AFG’s Level 1 financial instruments consist primarily of publicly traded equity securities, highly liquid government bonds for which quoted market prices in active markets are available and short-term investments of managed investment entities.

Level 2 — Quoted prices for similar instruments in active markets; quoted prices for identical or similar assets or liabilities in inactive markets (markets in which there are few transactions, the prices are not current, price quotations vary substantially over time or among market makers, or in which little information is released publicly); and valuations based on other significant inputs that are observable in active markets. AFG’s Level 2 financial instruments include corporate and municipal fixed maturity securities, asset-backed securities (“ABS”), mortgage-backed securities (“MBS”), certain non-affiliated common stocks and investments of managed investment entities priced using observable inputs. Level 2 inputs include benchmark yields, reported trades, corroborated broker/dealer quotes, issuer spreads and benchmark securities. When non-binding broker quotes can be corroborated by comparison to similar securities priced using observable inputs, they are classified as Level 2.

Level 3 — Valuations derived from market valuation techniques generally consistent with those used to estimate the fair values of Level 2 financial instruments in which one or more significant inputs are unobservable or when the market for a security exhibits significantly less liquidity relative to markets supporting Level 2 fair value measurements. The unobservable inputs may include management’s own assumptions about the assumptions market participants would use based on the best information available at the valuation date. Financial instruments whose fair value is estimated based on non-binding broker quotes or internally developed using significant inputs not based on, or corroborated by, observable market information are classified as Level 3.

The contingent consideration liability (included in other liabilities in AFG’s Balance Sheet) relates primarily to AFG’s acquisition of Verikai in December 2021. This estimated fair value of this liability is evaluated at each balance sheet date with changes in fair value recognized in net earnings. To estimate the fair value of the contingent consideration liability related to the Verikai acquisition ($23 million at June 30, 2023), AFG uses a weighted probability-based income approach which includes significant unobservable inputs and is classified as Level 3. There was no change to the estimated fair value of this liability during the first six months of 2023.

As discussed in Note A — “Accounting Policies — Managed Investment Entities,” AFG has set the carrying value of its CLO liabilities equal to the fair value of the CLO assets (which have more observable fair values) as an alternative to reporting those liabilities at separately measured fair values. As a result, the CLO liabilities are categorized within the fair value hierarchy on the same basis (proportionally) as the related CLO assets. Since the portion of the CLO liabilities allocated to Level 3 is derived from the fair value of the CLO assets, these amounts are excluded from the progression of Level 3 financial instruments.

AFG’s management is responsible for the valuation process and uses data from outside sources (including nationally recognized pricing services and broker/dealers) in establishing fair value. AFG’s internal investment professionals are a group of approximately 20 investment professionals whose primary responsibility is to manage AFG’s investment portfolio. These professionals monitor individual investments as well as overall industries and are active in the financial markets on a daily basis. The group is led by AFG’s chief investment officer, who reports directly to one of AFG’s Co-CEOs. Valuation techniques utilized by pricing services and prices obtained from external sources are reviewed by AFG’s internal investment professionals who are familiar with the securities being priced and the markets in which they trade to ensure the fair value determination is representative of an exit price. To validate the appropriateness of the prices obtained, these investment managers consider widely published indices (as benchmarks), recent trades, changes in interest rates, general economic conditions and the credit quality of the specific issuers. In addition, AFG communicates directly with the pricing services regarding the methods and assumptions used in pricing, including verifying, on a test basis, the inputs used by the service to value specific securities.

Approximately 7% of the total assets carried at fair value at June 30, 2023, were Level 3 assets. Approximately 10% ($117 million) of those Level 3 assets were priced using non-binding broker quotes, for which there is a lack of transparency as to the inputs used to determine fair value. Details as to the quantitative inputs are neither provided by the brokers nor otherwise reasonably obtainable by AFG. Approximately 3% ($37 million) of the Level 3 assets were priced by pricing services where either a single price was not corroborated, prices varied enough among the providers, or other market factors led management to determine these securities be classified as Level 3 assets. Approximately 27% ($316 million) of the Level 3 assets were equity investments in limited partnerships and similar investments that do not

qualify for equity method accounting whose prices were determined based on financial information provided by the limited partnerships.

Internally developed prices for fixed maturities are estimated using a variety of inputs, including appropriate credit spreads over the treasury yield (of a similar duration), trade information and prices of comparable securities and other security specific features (such as optional early redemption). Internally developed Level 3 asset fair values represent approximately 60% ($690 million) of the total fair value of Level 3 assets at June 30, 2023. Approximately 67% ($462 million) of these internally developed Level 3 assets are priced using a pricing model that uses a discounted cash flow approach to estimate the fair value of fixed maturity securities. The credit spread applied by management is the significant unobservable input of the pricing model. In instances where the security is currently callable at par value and the pricing model suggests a higher price, management caps the fair value at par value. Approximately 18% ($123 million) of the internally developed Level 3 assets are equity securities which are priced primarily using internal models with some inputs that are not market observable. Management believes that any justifiable changes in unobservable inputs used to determine internally developed fair values would not have resulted in a material change in AFG’s financial position.

Changes in balances of Level 3 financial assets and liabilities carried at fair value during the second quarter and first six months of 2023 and 2022 are presented below (in millions). The transfers into and out of Level 3 were due to changes in the availability of market observable inputs. All transfers are reflected in the table at fair value as of the end of the reporting period.

(*)92% of the carrying value relates to underlying investments in multi-family properties at both June 30, 2023 and December 31, 2022.

The earnings (losses) from these investments are generally reported on a quarter lag due to the timing required to obtain the necessary information from the funds. AFG regularly reviews and discusses fund performance with the fund managers to corroborate the reasonableness of the underlying reported asset values and to assess whether any events have occurred within the lag period that may materially affect the valuation of these investments.

With respect to partnerships and similar investments, AFG had unfunded commitments of $407 million and $396 million as of June 30, 2023 and December 31, 2022, respectively.

The following table shows gross unrealized losses (dollars in millions) on available for sale fixed maturities by investment category and length of time that individual securities have been in a continuous unrealized loss position at the following balance sheet dates.

At June 30, 2023, the gross unrealized losses on fixed maturities of $627 million relate to approximately 1,800 securities. Investment grade securities (as determined by nationally recognized rating agencies) represented approximately 95% of the gross unrealized loss and 95% of the fair value of securities with unrealized losses.

To evaluate fixed maturities for expected credit losses (impairment), management considers whether the unrealized loss is credit-driven or a result of changes in market interest rates, the extent to which fair value is less than cost basis, historical operating, balance sheet and cash flow data from the issuer, third party research and communications with industry specialists and discussions with issuer management.

AFG analyzes its MBS for expected credit losses (impairment) each quarter based upon expected future cash flows. Management estimates expected future cash flows based upon its knowledge of the MBS market, cash flow projections (which reflect loan to collateral values, subordination, vintage and geographic concentration) received from independent sources, implied cash flows inherent in security ratings and analysis of historical payment data.

Management believes AFG will recover its cost basis (net of any allowance) in the securities with unrealized losses and that AFG has the ability to hold the securities until they recover in value and had no intent to sell them at June 30, 2023.

A progression of the allowance for expected credit losses on available for sale fixed maturity securities is shown below (in millions):

(*)Includes mortgage-backed securities, collateralized loan obligations and other asset-backed securities.

In the first six months of 2023 and 2022, AFG did not purchase any securities with expected credit losses.

The table below sets forth the scheduled maturities of AFG’s available for sale fixed maturities as of June 30, 2023 (dollars in millions). Securities with sinking funds are reported at average maturity. Actual maturities may differ from contractual maturities because certain securities may be called or prepaid by the issuers.

Certain risks are inherent in fixed maturity securities, including loss upon default, price volatility in reaction to changes in interest rates, and general market factors and risks associated with reinvestment of proceeds due to prepayments or redemptions in a period of declining interest rates.

There were no investments in individual issuers that exceeded 10% of shareholders’ equity at June 30, 2023 or December 31, 2022.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives

Derivatives

As discussed under “Derivatives” in Note A — “Accounting Policies,” AFG uses derivatives to mitigate certain market risks related to its investment portfolio and deferred compensation obligations to employees.

The following table presents the classification of derivative assets and liabilities included in AFG’s Balance Sheet at fair value (in millions):

		June 30, 2023				December 31, 2022
	Balance Sheet Line	Asset		Liability		Asset		Liability
Derivatives designated and qualifying as cash flow hedges:
Interest rate swaps	Other assets/Other liabilities	$	—	$	41	$	—	$	37
Derivatives not designated as hedging instruments:
Fixed maturities with embedded derivatives	Fixed maturities	92		—		40		—
Total return swap	Other assets/Other liabilities	4		—		—		5
		$	96	$	41	$	40	$	42

AFG’s interest rate swaps are designated and qualify as highly effective cash flow hedges to mitigate interest rate risk related to certain floating-rate securities included in AFG’s portfolio of fixed maturity securities. The purpose of each of these swaps is to effectively convert a portion of AFG’s floating-rate fixed maturity securities to fixed rates by offsetting the variability in cash flows attributable to changes in short-term reference rates (LIBOR or SOFR).

Under the terms of the swaps, AFG receives fixed-rate interest payments in exchange for variable interest payments based on short-term LIBOR or SOFR. The notional amounts of the interest rate swaps generally decline over each swap’s respective life (the swaps expire between July 2024 and July 2028) in anticipation of the expected decline in AFG’s portfolio of fixed maturity securities with floating interest rates based on short-term LIBOR or SOFR. The total outstanding notional amount of AFG’s interest rate swaps was $1.35 billion at June 30, 2023 compared to $1.25 billion at December 31, 2022, reflecting the issuance of four new swaps with a total notional amount of $170 million in the first six months of 2023, partially offset by scheduled amortization. In the second quarter of 2023 and 2022, a loss of $7 million and income of $1 million, respectively, and in the first six months of 2023 and 2022, a loss of $12 million and income of $2 million, respectively, were reclassified from AOCI to net earnings. A collateral receivable supporting these swaps of $68 million and $62 million at June 30, 2023 and December 31, 2022, respectively, is included in other assets in AFG’s Balance Sheet.

The fixed maturities with embedded derivatives consist of convertible fixed maturity securities and interest-only and principal-only MBS. AFG records the change in the fair value of these securities in earnings. These investments are part of AFG’s overall investment strategy and represent a small component of AFG’s overall investment portfolio.

AFG is exposed to fair value changes from certain equity and fixed maturity market-based exposures related to its deferred compensation obligations to certain employees. To mitigate this risk, AFG entered into a total return swap in 2022. A payable of $3 million to return collateral related to this swap is included in other liabilities in AFG’s Balance Sheet at June 30, 2023 and a collateral receivable of $7 million supporting this swap is included in other assets in AFG’s Balance Sheet at December 31, 2022.

The following table summarizes the gains (losses) included in AFG’s Statement of Earnings for changes in the fair value of derivatives for the second quarter and six months ended June 30, 2023 and 2022 (in millions):

		Three months ended June 30,				Six months ended June 30,
	Statement of Earnings Line	2023		2022		2023		2022
Qualifying cash flow hedges - gains (losses) reclassified from AOCI to net earnings:
Interest rate swaps	Net investment income	$	(7)	$	1	$	(12)	$	2
Non-designated hedges - gains (losses) included in net earnings:
Fixed maturities with embedded derivatives	Realized gains (losses) on securities	(4)		(3)		(3)		(8)
Fixed maturities with embedded derivatives	Net investment income	7		—		10		—

Earnings (losses) on non-designated hedges		6		(7)		16		(12)
Total earnings (losses) on derivatives		$	(1)	$	(6)	$	4	$	(10)

Based on forward interest rate curves at June 30, 2023, management estimates that it will reclassify approximately $25 million of pre-tax net losses on interest rate swaps in AOCI to net investment income over the next twelve months. The actual amount will vary based on changes in SOFR.

Managed Investment Entities

Managed Investment Entities

AFG is the investment manager and it has investments ranging from 7.4% to 100% of the most subordinate debt tranche of sixteen active collateralized loan obligation entities (“CLOs”), which are considered variable interest entities. AFG also owns portions of the senior debt tranches of certain of these CLOs. Upon formation between 2012 and 2023, these entities issued securities in various senior and subordinate classes and invested the proceeds primarily in secured bank loans, which serve as collateral for the debt securities issued by each CLO. None of the collateral was purchased from AFG. AFG’s investments in the subordinate debt tranches of these entities receive residual income from the CLOs only after the CLOs pay expenses (including management fees to AFG) and interest on and returns of capital to senior levels of debt securities. There are no contractual requirements for AFG to provide additional funding for these entities. AFG has not provided and does not intend to provide any financial support to these entities.

AFG’s maximum exposure to economic loss on the CLOs that it manages is limited to its investment in those CLOs, which had an aggregate fair value of $136 million (including $85 million invested in the most subordinate tranches and $19 million invested in a temporary warehousing entity) at June 30, 2023, and $115 million at December 31, 2022.

In March 2023, AFG formed one new CLO, which issued $407 million face amount of liabilities (including $16 million face amount purchased by AFG). In May 2022, AFG formed one new CLO, which issued $404 million face amount of liabilities (including $13 million face amount purchased by AFG).

The following table shows a progression of the fair value of AFG's investment in CLO tranches (in millions):

	Three months ended June 30,				Six months ended June 30,
	2023		2022		2023		2022

(*)Excludes $19 million invested in a temporary warehousing entity at June 30, 2023 that was established to provide AFG the ability to form a new CLO.

The revenues and expenses of the CLOs are separately identified in AFG’s Statement of Earnings, after the elimination of management fees and earnings attributable to AFG as measured by the change in the fair value of AFG’s investments in the CLOs. Selected financial information related to the CLOs is shown below (in millions):

CLO earnings (losses) attributable to AFG	5		(12)		6		(14)

(*)Included in revenues in AFG’s Statement of Earnings.

The aggregate unpaid principal balance of the CLOs’ fixed maturity investments exceeded the fair value of the investments by $230 million and $339 million at June 30, 2023 and December 31, 2022, respectively. The aggregate unpaid principal balance of the CLOs’ debt exceeded its carrying value by $353 million and $413 million at those dates. The CLO assets include loans with an aggregate fair value of $5 million at June 30, 2023 and $4 million at December 31, 2022, for which the CLOs are not accruing interest because the loans are in default (aggregate unpaid principal balance of $15 million at June 30, 2023 and $17 million at December 31, 2022).

In addition to the CLOs that it manages, AFG had investments in CLOs that are managed by third parties (therefore not consolidated), which are included in available for sale fixed maturity securities and had a fair value of $1.86 billion at June 30, 2023 and $1.92 billion at December 31, 2022.

On January 1, 2023, the two major tax provisions of the Inflation Reduction Act (“IRA”) became effective. The IRA created a new corporate alternative minimum tax (“AMT”) based on the earnings that a company reports in its financial statements and imposes a 1% excise tax on corporate stock repurchases. Due to the lack of specific guidance at this time, AFG cannot determine whether it will be subject to the new AMT. Any AMT incurred would be available to offset AFG’s taxes payable under the standard calculation in future periods. Accordingly, the AMT is a timing difference and would result in the recording of an offsetting deferred tax asset with no impact on overall income tax expense. The excise tax on stock repurchases in excess of any issuances is recorded as part of the cost of the repurchases directly in shareholders’ equity.

Net decrease in the provision for claims of prior years	(125)		(173)
Total losses and LAE incurred	1,725		1,467
Payments for losses and LAE of:

Gross unpaid losses and LAE included in the balance sheet at end of period	$	11,925	$	11,201

The net decrease in the provision for claims of prior years during the first six months of 2023 reflects (i) lower than anticipated losses in the crop business, lower than expected claim frequency and severity in the trucking business and lower than anticipated claim frequency in the property and inland marine business (within the Property and transportation sub-segment), (ii) lower than anticipated claim severity in the workers’ compensation businesses, lower than expected claim frequency in the executive liability and environmental businesses and favorable reserve development related to COVID-19 losses across several businesses (within the Specialty casualty sub-segment) and (iii) lower than anticipated claim frequency in the trade credit and financial institutions businesses and lower than expected claim frequency and severity in the surety business (within the Specialty financial sub-segment). This favorable development was partially offset by higher than anticipated claim severity in the public sector and excess liability businesses (within the Specialty casualty sub-segment).

The net decrease in the provision for claims of prior years during the first six months of 2022 reflects (i) lower than anticipated losses in the crop business, lower than expected claim frequency in the trucking and ocean marine businesses and at the Singapore branch, lower than expected claim frequency and severity in the aviation business and lower than anticipated claim severity in the property and inland marine business (within the Property and transportation sub-segment), (ii) lower than anticipated claim severity in the workers’ compensation businesses, lower than expected claim frequency in the executive liability business and lower than anticipated claim frequency and severity in the excess and surplus business (within the Specialty casualty sub-segment) and (iii) lower than anticipated claim frequency in the surety, trade credit and financial institutions businesses (within the Specialty financial sub-segment). This favorable development was partially offset by (i) higher than anticipated claim severity in the targeted markets and excess liability businesses (within the Specialty casualty sub-segment) and (ii) net adverse development associated with AFG’s internal reinsurance program (within Other specialty).

Subsequent Events [Abstract]
Subsequent Event	Subsequent EventOn July 3, 2023, AFG completed the acquisition of Crop Risk Services (“CRS”) from American International Group (“AIG”). CRS is a primary crop insurance general agent based in Decatur, Illinois, with crop year 2022 gross written premiums of approximately $1.2 billion and was the seventh largest provider of multi-peril crop insurance in the United States based on 2022 premiums. At closing, AFG paid AIG approximately $235 million (based on an estimated $25 million in net tangible assets) using cash on hand. The sale is subject to post-closing adjustments which are expected to be finalized during the third quarter of 2023. The purchase price in excess of the net tangible assets acquired ($210 million) will be recorded as a combination of amortizing intangible assets (primarily related to existing agency relationships) and goodwill. AFG expensed $3 million of acquisition expenses incurred.AFG’s Great American Insurance Company has been providing crop-hail coverage since 1915 and began writing multi-peril crop insurance in 1980 after Congress authorized the program. Great American’s existing Crop Division generated gross written premiums of approximately $1.8 billion in 2022 and was the fifth largest provider of multi-peril crop insurance in the United States.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation   The accompanying consolidated financial statements for American Financial Group, Inc. and its subsidiaries (“AFG”) are unaudited; however, management believes that all adjustments (consisting only of normal recurring accruals unless otherwise disclosed herein) necessary for fair presentation have been made. The results of operations for interim periods are not necessarily indicative of results to be expected for the year. The financial statements have been prepared in accordance with the instructions to Form 10-Q and, therefore, do not include all information and footnotes necessary to be in conformity with U.S. generally accepted accounting principles (“GAAP”).

Certain reclassifications have been made to prior periods to conform to the current year’s presentation. All significant intercompany balances and transactions have been eliminated. The results of operations of companies since their formation or acquisition are included in the consolidated financial statements. Events or transactions occurring subsequent to June 30, 2023, and prior to the filing of this Form 10-Q, have been evaluated for potential recognition or disclosure herein.

The preparation of the financial statements requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Changes in circumstances could cause actual results to differ materially from those estimates.

Fair Value Measurements

Fair Value Measurements   Accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants on the measurement date. The standards establish a hierarchy of valuation techniques based on whether the assumptions that market participants would use in pricing the asset or liability (“inputs”) are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect AFG’s assumptions about the assumptions market participants would use in pricing the asset or liability. AFG did not have any material nonrecurring fair value measurements in the first six months of 2023.

Accounting standards for measuring fair value are based on inputs used in estimating fair value. The three levels of the hierarchy are as follows:

Level 1 — Quoted prices for identical assets or liabilities in active markets (markets in which transactions occur with sufficient frequency and volume to provide pricing information on an ongoing basis). AFG’s Level 1 financial instruments consist primarily of publicly traded equity securities, highly liquid government bonds for which quoted market prices in active markets are available and short-term investments of managed investment entities.

Level 2 — Quoted prices for similar instruments in active markets; quoted prices for identical or similar assets or liabilities in inactive markets (markets in which there are few transactions, the prices are not current, price quotations vary substantially over time or among market makers, or in which little information is released publicly); and valuations based on other significant inputs that are observable in active markets. AFG’s Level 2 financial instruments include corporate and municipal fixed maturity securities, asset-backed securities (“ABS”), mortgage-backed securities (“MBS”), certain non-affiliated common stocks and investments of managed investment entities priced using observable inputs. Level 2 inputs include benchmark yields, reported trades, corroborated broker/dealer quotes, issuer spreads and benchmark securities. When non-binding broker quotes can be corroborated by comparison to similar securities priced using observable inputs, they are classified as Level 2.

Level 3 — Valuations derived from market valuation techniques generally consistent with those used to estimate the fair values of Level 2 financial instruments in which one or more significant inputs are unobservable or when the market for a security exhibits significantly less liquidity relative to markets supporting Level 2 fair value measurements. The unobservable inputs may include management’s own assumptions about the assumptions market participants would use based on the best information available at the valuation date. Financial instruments whose fair value is estimated based on non-binding broker quotes or internally developed using significant inputs not based on, or corroborated by, observable market information are classified as Level 3.

The contingent consideration liability (included in other liabilities in AFG’s Balance Sheet) relates primarily to AFG’s acquisition of Verikai in December 2021. This estimated fair value of this liability is evaluated at each balance sheet date with changes in fair value recognized in net earnings. To estimate the fair value of the contingent consideration liability related to the Verikai acquisition ($23 million at June 30, 2023), AFG uses a weighted probability-based income approach which includes significant unobservable inputs and is classified as Level 3. There was no change to the estimated fair value of this liability during the first six months of 2023.

As discussed in Note A — “Accounting Policies — Managed Investment Entities,” AFG has set the carrying value of its CLO liabilities equal to the fair value of the CLO assets (which have more observable fair values) as an alternative to reporting those liabilities at separately measured fair values. As a result, the CLO liabilities are categorized within the fair value hierarchy on the same basis (proportionally) as the related CLO assets. Since the portion of the CLO liabilities allocated to Level 3 is derived from the fair value of the CLO assets, these amounts are excluded from the progression of Level 3 financial instruments.

AFG’s management is responsible for the valuation process and uses data from outside sources (including nationally recognized pricing services and broker/dealers) in establishing fair value. AFG’s internal investment professionals are a group of approximately 20 investment professionals whose primary responsibility is to manage AFG’s investment portfolio. These professionals monitor individual investments as well as overall industries and are active in the financial markets on a daily basis. The group is led by AFG’s chief investment officer, who reports directly to one of AFG’s Co-CEOs. Valuation techniques utilized by pricing services and prices obtained from external sources are reviewed by AFG’s internal investment professionals who are familiar with the securities being priced and the markets in which they trade to ensure the fair value determination is representative of an exit price. To validate the appropriateness of the prices obtained, these investment managers consider widely published indices (as benchmarks), recent trades, changes in interest rates, general economic conditions and the credit quality of the specific issuers. In addition, AFG communicates directly with the pricing services regarding the methods and assumptions used in pricing, including verifying, on a test basis, the inputs used by the service to value specific securities.

Investments

Investments   Equity securities other than those accounted for under the equity method are reported at fair value with holding gains and losses generally recorded in realized gains (losses) on securities. However, AFG records holding gains and losses on limited partnerships and similar investments that do not qualify for equity method accounting (and are therefore carried at fair value), and certain other securities classified at purchase as “fair value through net investment income” in net investment income.

Fixed maturity securities classified as “available for sale” are reported at fair value with unrealized gains and losses included in accumulated other comprehensive income (“AOCI”) in AFG’s Balance Sheet. Fixed maturity securities classified as “trading” are reported at fair value with changes in unrealized holding gains or losses during the period included in net investment income. Mortgage loans (net of any allowance) are carried primarily at the aggregate unpaid balance.

Realized gains or losses on the disposal of fixed maturity securities are determined on the specific identification basis. Premiums and discounts on fixed maturity securities are amortized using the effective interest method. Mortgage-backed securities (“MBS”) are amortized over a period based on estimated future principal payments, including prepayments. Prepayment assumptions are reviewed periodically and adjusted to reflect actual prepayments and changes in expectations.

Limited partnerships and similar investments are generally accounted for using the equity method of accounting. Under the equity method, AFG records its share of the earnings or losses of the investee based on when it is reported by the investee in its financial statements rather than in the period in which the investee declares a dividend. AFG’s share of the earnings or losses from equity method investments is generally recorded on a quarter lag due to the timing of the receipt of the investee’s financial statements. AFG’s equity in the earnings (losses) of limited partnerships and similar investments is included in net investment income.

Credit Losses on Financial Instruments

Credit Losses on Fixed Maturity Investments   When a decline in the value of an available for sale fixed maturity is considered to be other-than-temporary at the balance sheet date, an allowance for credit losses (impairment), including any write-off of accrued interest, is charged to earnings (included in realized gains (losses) on securities). If management can assert that it does not intend to sell the security and it is not more likely than not that it will have to sell it before recovery of its amortized cost basis (net of allowance), then the impairment is separated into two components: (i) the allowance related to credit losses (recorded in earnings) and (ii) the amount related to all other factors (recorded in other comprehensive income). The credit-related portion is measured by comparing a security’s amortized cost to the present value of its current expected cash flows discounted at its effective yield prior to the charge. The allowance is limited to the difference between a security’s amortized cost basis and its fair value. Subsequent increases or decreases in expected credit losses are recorded immediately in net earnings through realized gains (losses). If management intends to sell an impaired security, or it is more likely than not that it will be required to sell the security before recovery, an impairment is recorded in earnings to reduce the amortized cost (net of allowance) of that security to fair value.Credit Losses on Financial Instruments Measured at Amortized Cost   Credit-related impairments for financial instruments measured at amortized cost (mortgage loans, premiums receivable and reinsurance recoverables) reflect estimated credit losses expected over the life of an exposure or pool of exposures. The estimate of expected credit losses considers historical information, current information, as well as reasonable and supportable forecasts, including estimates of prepayments. Expected credit losses, and subsequent increases or decreases in such expected losses, are recorded immediately through net earnings as an allowance that is deducted from the amortized cost basis of the financial asset, with the net carrying value of the financial asset presented on the balance sheet at the amount expected to be collected.

Derivatives

Derivatives   Derivatives included in AFG’s Balance Sheet are recorded at fair value. Changes in fair value of derivatives are included in earnings unless the derivatives are designated and qualify as highly effective cash flow hedges. AFG’s derivatives that do not qualify for hedge accounting under GAAP consist primarily of components of certain fixed maturity securities (convertible fixed maturities and interest-only and principal-only MBS) and a total return swap related to its deferred compensation obligations to employees.

To qualify for hedge accounting, at the inception of a derivative contract, AFG formally documents the relationship between the terms of the hedge and the hedged items and its risk management objective. This documentation includes defining how hedge effectiveness is evaluated at the inception date and over the life of the derivative.

Changes in the fair value of derivatives that are designated and qualify as highly effective cash flow hedges are recorded in AOCI and are reclassified into earnings when the variability of the cash flows from the hedged items impacts earnings. When the change in the fair value of a qualifying cash flow hedge is included in earnings, it is included in the same line item in the statement of earnings as the cash flows from the hedged item. AFG uses interest rate swaps that are designated and qualify as highly effective cash flow hedges to mitigate interest rate risk related to certain floating-rate securities.

Goodwill

Goodwill   Goodwill represents the excess of cost of subsidiaries over AFG’s equity in their underlying net assets at the date of acquisition. Goodwill is not amortized, but is subject to an impairment test at least annually. An entity is not required to complete the quantitative annual goodwill impairment test on a reporting unit if the entity elects to perform a qualitative analysis and determines that it is more likely than not that the reporting unit’s fair value exceeds its carrying amount.

Reinsurance

Reinsurance   Amounts recoverable from reinsurers are estimated in a manner consistent with the claim liability associated with the reinsured policies. AFG reports as assets (i) the estimated reinsurance recoverable on paid and unpaid losses, including an estimate for losses incurred but not reported, and (ii) amounts paid or due to reinsurers applicable to the unexpired terms of policies in force. Payable to reinsurers includes ceded premiums due to reinsurers, as well as ceded premiums retained by AFG under contracts to fund ceded losses as they become due. AFG also assumes reinsurance from other companies. Earnings on reinsurance assumed is recognized based on information received from ceding companies.

Deferred Policy Acquisition Costs (“DPAC”)

Deferred Policy Acquisition Costs (“DPAC”)   Policy acquisition costs (principally commissions, premium taxes and certain underwriting and policy issuance costs) directly related to the successful acquisition or renewal of an insurance contract are deferred. DPAC is limited based upon recoverability without any consideration for anticipated investment income and is charged against income ratably over the terms of the related policies. A premium deficiency is recognized if the sum of expected claims costs, claims adjustment expenses and unamortized acquisition costs exceed the related unearned premiums. A premium deficiency is first recognized by charging any unamortized acquisition costs to expense to the extent required to eliminate the deficiency. If the premium deficiency is greater than unamortized acquisition costs, a liability is accrued for the excess deficiency and reported with unpaid losses and loss adjustment expenses.

Managed Investment Entities

Managed Investment Entities   A company is considered the primary beneficiary of, and therefore must consolidate, a variable interest entity (“VIE”) based primarily on its ability to direct the activities of the VIE that most significantly impact that entity’s economic performance and the obligation to absorb losses of, or receive benefits from, the entity that could potentially be significant to the VIE.

AFG manages, and has investments in, collateralized loan obligations (“CLOs”) that are VIEs (see Note F — “Managed Investment Entities”). AFG has determined that it is the primary beneficiary of these CLOs because (i) its role as asset manager gives it the power to direct the activities that most significantly impact the economic performance of the CLOs and (ii) through its investment in the CLO debt tranches, it has exposure to CLO losses (limited to the amount AFG invested) and the right to receive CLO benefits that could potentially be significant to the CLOs.

Because AFG has no right to use the CLO assets and no obligation to pay the CLO liabilities, the assets and liabilities of the CLOs are shown separately in AFG’s Balance Sheet. AFG has elected the fair value option for reporting on the CLO assets and liabilities to improve the transparency of financial reporting related to the CLOs. The net gain or loss from accounting for the CLO assets and liabilities at fair value is presented separately in AFG’s Statement of Earnings.

The fair values of a CLO’s assets may differ from the separately measured fair values of its liabilities even though the CLO liabilities only have recourse to the CLO assets. AFG has set the carrying value of the CLO liabilities equal to the fair value of the CLO assets (which have more observable fair values) as an alternative to reporting those liabilities at a separately measured fair value. CLO earnings attributable to AFG’s shareholders are measured by the change in the fair value of AFG’s investments in the CLOs and management fees earned.

At June 30, 2023, assets and liabilities of managed investment entities included $105 million in assets and $86 million in liabilities of a temporary warehousing entity that was established to provide AFG the ability to form a new CLO. At closing, all warehoused assets will be transferred to the new CLO and the liabilities will be repaid.

Unpaid Losses and Loss Adjustment Expenses

Unpaid Losses and Loss Adjustment Expenses   The net liabilities stated for unpaid claims and for expenses of investigation and adjustment of unpaid claims represent management’s best estimate and are based upon (i) the accumulation of case estimates for losses reported prior to the close of the accounting period on direct business written; (ii) estimates received from ceding reinsurers and insurance pools and associations; (iii) estimates of unreported losses (including possible development on known claims) based on past experience; (iv) estimates based on experience of expenses for investigating and adjusting claims; and (v) the current state of the law and coverage litigation. Establishing reserves for asbestos, environmental and other mass tort claims involves considerably more judgment than other types of claims due to, among other things, inconsistent court decisions, an increase in bankruptcy filings as a result of asbestos-related liabilities, novel theories of coverage, and judicial interpretations that often expand theories of recovery and broaden the scope of coverage.

Loss reserve liabilities are subject to the impact of changes in claim amounts and frequency and other factors. Changes in estimates of the liabilities for losses and loss adjustment expenses are reflected in the statement of earnings in the period in which determined. Despite the variability inherent in such estimates, management believes that the liabilities for unpaid losses and loss adjustment expenses are adequate and reasonable.

Debt Issuance Costs

Debt Issuance Costs   Debt issuance costs related to AFG’s outstanding debt are presented in its Balance Sheet as a direct reduction in the carrying value of long-term debt and are amortized over the life of the related debt using the effective interest method as a component of interest expense. Debt issuance costs related to AFG’s revolving credit facilities are included in other assets in AFG’s Balance Sheet.

Leases

Leases   Leases for terms of longer than one year are recognized as assets and liabilities for the rights and obligations created by those leases on the balance sheet based on the present value of contractual cash flows.

At June 30, 2023 AFG has a $190 million lease liability included in other liabilities and a lease right-of-use asset of $167 million included in other assets compared to $116 million and $103 million, respectively, at December 31, 2022. The increase in the lease liability and right-of-use asset is due primarily to the renewal of AFG’s largest office lease which extended the term for an additional 10 years.

Premium Recognition

Premium Recognition   Property and casualty premiums are earned generally over the terms of the policies on a pro rata basis. Unearned premiums represent that portion of premiums written, which is applicable to the unexpired terms of policies in force. On reinsurance assumed from other insurance companies or written through various underwriting organizations, unearned premiums are based on information received from such companies and organizations.

Income Taxes

Income Taxes   Deferred income taxes are calculated using the liability method. Under this method, deferred income tax assets and liabilities are determined based on differences between financial reporting and tax bases and are measured using enacted tax rates. A valuation allowance is established to reduce total deferred tax assets to an amount that will more likely than not be realized. The effect of a change in tax rates on deferred tax assets and liabilities is recorded in net earnings in the period that includes the enactment date.

AFG recognizes the tax benefits of uncertain tax positions only when the position is more likely than not to be sustained under examination by the appropriate taxing authority. Interest and penalties on AFG’s reserve for uncertain tax positions are recognized as a component of tax expense.

Stock-Based Compensation

Stock-Based Compensation   All share-based grants are recognized as compensation expense on a straight-line basis over their vesting periods based on their calculated fair value at the date of grant.

AFG records excess tax benefits or deficiencies for share-based payments through income tax expense in the statement of earnings. In addition, AFG accounts for forfeitures of awards when they occur.

Benefit Plans

Benefit Plans   AFG provides retirement benefits to qualified employees of participating companies through the AFG 401(k) Retirement and Savings Plan, a defined contribution plan. AFG makes all contributions to the retirement fund portion of the plan and matches a percentage of employee contributions to the savings fund. Company contributions are expensed in the year for which they are declared. AFG and many of its subsidiaries provide health care and life insurance benefits to eligible retirees. AFG also provides postemployment benefits to former or inactive employees (primarily those on disability) who were not deemed retired under other company plans. The projected future cost of providing these benefits is expensed over the period employees earn such benefits.

Earnings Per Share

Earnings Per Share   Although basic earnings per share only considers shares of common stock outstanding during the period, the calculation of diluted earnings per share includes the following adjustments to weighted average common shares related to stock-based compensation plans: second quarter 2023 and 2022 — 0.1 million and 0.2 million; first six months of 2023 and 2022 — 0.1 million and 0.6 million.

There were no anti-dilutive potential common shares for the second quarter or the first six months of 2023 or 2022.

Statement of Cash Flows

Statement of Cash Flows   For cash flow purposes, “investing activities” are defined as making and collecting loans and acquiring and disposing of debt or equity instruments, property and equipment and businesses. “Financing activities” include obtaining resources from owners and providing them with a return on their investments, borrowing money and repaying amounts borrowed. All other activities are considered “operating.” Short-term investments having original maturities of three months or less when purchased are considered to be cash equivalents for purposes of the financial statements.

Segments of Operations

AFG reports its property and casualty insurance business in the following Specialty sub-segments: (i) Property and transportation, which includes physical damage and liability coverage for buses and trucks and other specialty transportation niches, inland and ocean marine, agricultural-related products and other commercial property coverages, (ii) Specialty casualty, which includes primarily excess and surplus, executive and professional liability, general liability, umbrella and excess liability, specialty coverages in targeted markets, customized programs for small to mid-sized businesses and workers’ compensation insurance, and (iii) Specialty financial, which includes risk management insurance programs for lending and leasing institutions (including equipment leasing and collateral and lender-placed mortgage property insurance), fidelity and surety products and trade credit insurance. Premiums and underwriting profit included under Other specialty represent business assumed by AFG’s internal reinsurance program from the operations that make up AFG’s other Specialty sub-segments and amortization of a deferred gain on a retroactive reinsurance transaction related to the sale of a business. AFG’s reportable segments and their components were determined based primarily upon similar economic characteristics, products and services.

Accumulated Other Comprehensive Income, Net of Tax ("AOCI")

Accumulated Other Comprehensive Income (Loss), Net of Tax (“AOCI”)   Comprehensive income is defined as all changes in shareholders’ equity except those arising from transactions with shareholders. Comprehensive income includes net earnings and other comprehensive income (loss), which consists primarily of changes in net unrealized gains or losses on available for sale fixed maturity securities.
