PART I

Item 1. Business

Introduction

American Financial Group, Inc. (“AFG” or the “Company”) is an insurance holding company. Through the operations of Great American Insurance Group, AFG is engaged primarily in property and casualty insurance, focusing on specialized commercial products for businesses, and in the sale of traditional fixed and indexed annuities in the retail, financial institutions, broker-dealer and registered investment advisor markets. The members of the Great American Insurance Group have been in business for over 145 years. Management believes that over 55% of the 2019 gross written premiums in AFG’s Specialty property and casualty group are produced by “top 10” ranked businesses and that AFG was also a “top ten” provider of fixed annuities in 2019, including the second largest seller of fixed-indexed annuities (“FIAs”) through financial institutions. AFG’s in-house team of investment professionals oversees the Company’s $55.25 billion investment portfolio.

AFG’s address is 301 East Fourth Street, Cincinnati, Ohio 45202; its phone number is (513) 579-2121. SEC filings, news releases, AFG’s Code of Ethics applicable to directors, officers and employees and other information may be accessed free of charge through AFG’s Internet site at: www.AFGinc.com. (Information on AFG’s Internet site is not part of this Form 10-K.) See Note C — “Segments of Operations” to the financial statements for information on AFG’s assets, revenues and earnings before income taxes by segment.

Building Long-Term Value for AFG Shareholders

AFG allows each of its businesses the autonomy to make decisions related to underwriting, claims and policy servicing. This entrepreneurial business model promotes agility, innovative product design, unique applications of pricing segmentation, as well as developing distribution strategies and building relationships in the markets served. Management believes that AFG’s ability to grow book value per share at a double-digit annual rate over time is evidence that the Company’s culture, business model and employee incentive plans create a compelling structure to build long-term value for AFG’s shareholders.

As highlighted in the illustration below, over the past 20 or so years, AFG has sharpened its focus on the businesses that management knows best. This has been accomplished through organic growth, carefully selected acquisitions, start-ups, and dispositions of underperforming or peripheral businesses. In August 2019, AFG announced the newly formed Accident & Health division. This business will build upon Great American’s existing array of Accident & Health Insurance coverages, focusing on customized coverages for organizations and educational institutions. In December 2019, AFG initiated plans to exit the Lloyd’s of London property and casualty market in 2020. AFG’s Lloyd’s operation, Neon (and its predecessor, Marketform), failed to achieve AFG’s profitability objectives since the purchase of Marketform in 2008. The exit from this business will allow AFG to reallocate capital to other insurance businesses and opportunities that have the potential to earn targeted returns on investment.

Property and Casualty Insurance Segment

General

AFG’s property and casualty insurance operations provide a wide range of commercial coverages through 34 insurance businesses (at December 31, 2019) that make up the Great American Insurance Group. AFG’s property and casualty insurance operations ultimately report to a single senior executive and operate under a business model that allows local decision-making for underwriting, claims and policy servicing in each of the niche operations. Each business is managed by experienced professionals in particular lines or customer groups and operates autonomously but with certain central controls and accountability. The decentralized approach allows each unit the autonomy necessary to respond to local and specialty market conditions while capitalizing on the efficiencies of centralized investment and administrative support functions. AFG’s property and casualty insurance operations had approximately 6,800 employees as of December 31, 2019. These operations are conducted through the subsidiaries listed in the following table, which includes independent financial strength ratings and 2019 gross written premiums (in millions) for each major subsidiary. These ratings are generally based on concerns for policyholders and agents and are not directed toward the protection of investors. AFG believes that maintaining a rating in the “A” category by A.M. Best is important to compete successfully in most lines of business.

	Ratings		Gross Written
	AM Best	S&P	Premiums
Insurance Group
Great American Insurance	A+	A+	$	4,857
National Interstate	A+	not rated	816

Neon Lloyd’s Syndicate	A	A+	567
Mid-Continent Casualty	A+	A+	142
Other			113
			$	7,299

The primary objectives of AFG’s property and casualty insurance operations are to achieve solid underwriting profitability and provide excellent service to its policyholders and agents. Underwriting profitability is measured by the combined ratio, which is a sum of the ratios of losses, loss adjustment expenses (“LAE”), underwriting expenses and policyholder dividends to premiums. A combined ratio under 100% indicates an underwriting profit. The combined ratio does not reflect investment income, other income, other expenses or federal income taxes.

While many costs included in underwriting are readily determined (commissions, administrative expenses and many of the losses on claims reported), the process of determining overall underwriting results is highly dependent upon the use of estimates in the case of losses incurred or expected but not yet reported or developed. Actuarial procedures and projections are used to obtain “point estimates” of ultimate losses. While the process is imprecise and develops amounts which are subject to change over time, management believes that the liabilities for unpaid losses and loss adjustment expenses are adequate.

Financial information is reported in accordance with U.S. generally accepted accounting principles (“GAAP”) for shareholder and other investor-related purposes and reported on a statutory basis for U.S. insurance regulatory purposes. Unless indicated otherwise, the financial information presented in this Form 10-K for AFG’s property and casualty insurance operations is presented based on GAAP. Statutory information is only prepared for AFG’s U.S.-based subsidiaries, which represented approximately 90% of AFG’s direct written premiums in 2019, and is provided for industry comparisons or where comparable GAAP information is not readily available.

Major differences for statutory accounting include charging policy acquisition costs to expense as incurred rather than spreading the costs over the periods covered by the policies; reporting investment grade bonds and redeemable preferred stocks at amortized cost rather than fair value; netting of reinsurance recoverables and prepaid reinsurance premiums against the corresponding liabilities rather than reporting such items separately; and charging to surplus certain GAAP assets, such as furniture and fixtures and agents’ balances over 90 days old.

5

AFG’s statutory combined ratio averaged 92.4% for the period 2010 to 2019 as compared to 100.6% for the property and casualty commercial lines industry over the same period. AFG believes that its specialty niche focus, product line diversification and underwriting discipline have contributed to the Company’s ability to consistently outperform the industry’s underwriting results. Management’s philosophy is to refrain from writing business that is not expected to produce an underwriting profit even if it is necessary to limit premium growth to do so.

Property and Casualty Results

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. See Note C — “Segments of Operations” to the financial statements for the reconciliation of AFG’s earnings before income taxes by significant business segment to the statement of earnings.

The following table shows the performance of AFG’s property and casualty insurance operations (dollars in millions):

	2019			2018			2017
Gross written premiums	$	7,299		$	6,840		$	6,502

As with other property and casualty insurers, AFG’s operating results can be adversely affected by unpredictable catastrophe losses. Certain natural disasters (hurricanes, severe storms, earthquakes, tornadoes, floods, etc.) and other incidents of major loss (explosions, civil disorder, terrorist events, fires, etc.) are classified as catastrophes by industry associations. Losses from these incidents are usually tracked separately from other business of insurers because of their sizable effects on overall operations. Total net losses to AFG’s insurance operations from current accident year catastrophes were $60 million in 2019, $103 million in 2018 and $140 million in 2017 and are included in the table above.

AFG generally seeks to reduce its exposure to catastrophes through individual risk selection, including minimizing coastal and known fault-line exposures, and through the purchase of reinsurance. AFG’s net exposure to a catastrophic earthquake or windstorm that industry models indicate should statistically occur once in every 500 years (a “500-year event”) is expected to be approximately 6% of AFG’s Shareholders’ Equity.

Property and Casualty Insurance Products

AFG is focused on growth opportunities in what it believes to be more profitable specialty businesses where AFG personnel are experts in particular lines of business or customer groups. The following are examples of AFG’s specialty businesses grouped by sub-segment:

Property and Transportation
Agricultural-related	Federally reinsured multi-peril crop (allied lines) insurance covering most perils as well as crop-hail, equine mortality and other coverages for full-time operating farms/ranches and agribusiness operations on a nationwide basis.
Commercial Automobile	Coverage for vehicles (such as buses and trucks) in a broad range of businesses including the moving and storage and transportation industries, as well as alternative risk transfer programs, and a specialized physical damage product for the trucking industry.
Property, Inland Marine and Ocean Marine	Coverage primarily for commercial properties, builders’ risk, contractors’ equipment, property, motor truck cargo, marine cargo, boat dealers, marina operators/dealers and excursion vessels.
Specialty Casualty
Excess and Surplus	Liability, umbrella and excess coverage for unique, volatile or hard to place risks, using rates and forms that generally do not have to be approved by state insurance regulators.
Executive and Professional Liability	Coverage for directors and officers of businesses and non-profit organizations, errors and omissions, cyber, and mergers and acquisitions.
General Liability	Coverage for contractor-related businesses, energy development and production risks, and environmental liability risks.
Targeted Programs	Coverage (primarily liability and property) for social service agencies, leisure, entertainment and non-profit organizations, customized solutions for other targeted markets and alternative risk programs using agency captives.
Umbrella and Excess Liability	Coverage in excess of primary layers.
Workers’ Compensation	Coverage for prescribed benefits payable to employees who are injured on the job.
Specialty Financial
Fidelity and Surety	Fidelity and crime coverage for government, mercantile and financial institutions and surety coverage for various types of contractors and public and private corporations.
Lease and Loan Services	Coverage for insurance risk management programs for lending and leasing institutions, including equipment leasing and collateral and lender-placed mortgage property insurance.

Management believes specialization is the key element to the underwriting success of these business units. These specialty businesses are opportunistic and premium volume will vary based on prevailing market conditions. AFG continually evaluates expansion in existing markets and opportunities in new specialty markets that meet its profitability objectives. Likewise, AFG will withdraw from markets that do not meet its profit objectives or business strategy.

The geographic distribution of statutory direct written premiums by AFG’s U.S.-based insurers for 2019, 2018 and 2017 is shown below. Just under 10% of AFG’s direct written premiums in 2019 were derived from non U.S.-based insurers.

In December 2019, AFG initiated actions to exit the Lloyd’s of London insurance market, which included placing its Lloyd’s subsidiaries including its Lloyd’s Managing Agency, Neon Underwriting Ltd., into run-off. Neon generated approximately 85% of the non U.S.-based direct written premiums in 2019.

Reinsurance

Consistent with standard practice of most insurance companies, AFG reinsures a portion of its property and casualty business with other insurance companies and assumes a relatively small amount of business from other insurers. AFG uses reinsurance for two primary purposes: (i) to provide higher limits of coverage than it would otherwise be willing to provide (i.e. large line capacity) and (ii) to protect its business by reducing the impact of catastrophes. The availability and cost of reinsurance are subject to prevailing market conditions, which may affect the volume and profitability of business that is written. AFG is subject to credit risk with respect to its reinsurers, as the ceding of risk to reinsurers does not relieve AFG of its liability to its insureds until claims are fully settled.

Reinsurance is provided on either a facultative or treaty basis. Facultative reinsurance is generally provided on a risk-by-risk basis. Individual risks are ceded and assumed based on an offer and acceptance of risk by each party to the transaction. AFG purchases facultative reinsurance, both pro rata and excess of loss, depending on the risk and available reinsurance markets. Treaty reinsurance provides for risks meeting prescribed criteria to be automatically ceded and assumed according to contract provisions.

Catastrophe Reinsurance AFG has taken steps to limit its exposure to wind and earthquake losses through individual risk selection, including minimizing coastal and known fault-line exposures, and purchasing catastrophe reinsurance. Catastrophe reinsurance is purchased separately for AFG’s U.S. property and casualty insurance group and for Neon,

10

AFG’s Lloyd’s insurance business. In addition, AFG purchases catastrophe reinsurance for its workers’ compensation businesses. Although the cost of catastrophe reinsurance varies depending on exposure and the level of worldwide loss activity, AFG continues to obtain reinsurance coverage in adequate amounts at acceptable rates.

In early 2019, Neon launched its second insurance-linked securities transaction through NCM Re (UK PCC) Ltd. (“NCM Re”), which provided $77 million in collateralized quota share reinsurance that assumed 17.1% of the Neon Lloyd’s syndicate’s property treaty reinsurance and direct and facultative portfolios. Losses are recovered from NCM Re before Neon’s catastrophe excess of loss reinsurance coverage applies. In addition to NCM Re, in 2019 Neon placed a quota share treaty, which covered 12.8% of Neon’s gross property losses. Also in 2019, Neon placed a 25.5% quota share reinsurance treaty, which covered its property insurance and a further 7.1% quota share treaty, which covered its property insurance placed under binding authorities.

In January 2020, AFG’s property and casualty insurance subsidiaries renewed substantially all of their catastrophe reinsurance coverages. For AFG’s U.S.-based operations, the Company continued to place $85 million of coverage in excess of a $15 million per event primary retention in the traditional reinsurance markets. In addition, AFG’s U.S.-based operations have a $34 million layer of coverage in excess of $100 million in catastrophe losses that will be up for renewal in June 2020. Neon placed $130 million of coverage in excess of a $15 million per event primary retention and $30 million of coverage in excess of $15 million per event on assumed business. In addition to Neon’s catastrophe excess of loss reinsurance coverage, Neon has placed a quota share treaty which covers 20% of Neon’s gross property losses with a $310 million event limit (maximum $62 million recoverable) and a further 25% quota share treaty covering its property insurance with a $185 million event limit (maximum $46 million recoverable), which supplements its catastrophe excess of loss reinsurance. Recoveries from Neon’s property insurance quota share treaties apply before calculating losses recoverable from the catastrophe excess of loss reinsurance.

In June 2017, AFG’s property and casualty insurance subsidiaries entered into a reinsurance agreement to obtain supplemental catastrophe protection through a catastrophe bond structure with Riverfront Re Ltd. (“Riverfront”). The reinsurance agreement provides supplemental reinsurance coverage up to 95% of $200 million (fully collateralized) for catastrophe losses in excess of $134 million of traditional catastrophe reinsurance (per occurrence and annual aggregate) occurring until December 31, 2020. In connection with the reinsurance agreement, Riverfront issued notes to unrelated investors for the full amount of coverage provided under the reinsurance agreement. Through December 31, 2019, AFG’s incurred catastrophe losses have not reached the level of attachment for the catastrophe bond structure. Riverfront is a variable interest entity in which AFG does not have a variable interest because the variability in Riverfront’s results will be absorbed entirely by the investors in Riverfront. Accordingly, Riverfront is not consolidated in AFG’s financial statements and the reinsurance agreement is accounted for as ceded reinsurance. AFG’s cost for this coverage is approximately $11 million per year.

The commercial marketplace requires large policy limits ($25 million or more) in several of AFG’s lines of business, including certain property, environmental, aviation, executive and professional liability, umbrella and excess liability, and fidelity and surety coverages. Since these limits exceed management’s desired exposure to an individual risk, AFG generally enters into reinsurance agreements to reduce its net exposure under such policies to an acceptable level. Reinsurance continues to be available for this large line capacity exposure with satisfactory pricing and terms.

In addition to the catastrophe and large line capacity reinsurance programs discussed above, AFG purchases reinsurance on a product-by-product basis. AFG regularly reviews the financial strength of its current and potential reinsurers. These reviews include consideration of credit ratings, available capital, claims paying history and expertise. This process periodically results in the transfer of risks to more financially secure reinsurers. Substantially all reinsurance is ceded to companies with investment grade S&P ratings or is secured by “funds withheld” or other collateral. Under “funds withheld” arrangements, AFG retains ceded premiums to fund ceded losses as they become due from the reinsurer. Recoverables from the following companies were individually between 5% and 11% of AFG’s total property and casualty reinsurance recoverable (including prepaid reinsurance premiums and net of payables to reinsurers) at December 31, 2019: Hannover Rueck SE, Munich Reinsurance America, Inc. and Swiss Reinsurance America Corporation. In addition, AFG has a reinsurance recoverable from Ohio Casualty Insurance Company of $137 million related to that company’s purchase of AFG’s commercial lines business in 1998. No other reinsurers exceeded 5% of AFG’s property and casualty reinsurance recoverable.

In addition to the coverage shown above, AFG reinsures a portion of its crop insurance business through the Federal Crop Insurance Corporation (“FCIC”). The FCIC offers both proportional (or “quota share”) and non-proportional coverages. The proportional coverage provides that a fixed percentage of risk is assumed by the FCIC. The non-proportional coverage allows AFG to select desired retention of risk on a state-by-state, county, crop or plan basis. AFG typically reinsures 15% to 25% of gross written premiums with the FCIC. AFG also purchases quota share reinsurance in the private market. This quota share provides for a ceding commission to AFG and a profit-sharing provision. During both 2019 and 2018, AFG reinsured 50% of premiums not reinsured by the FCIC in the private market and purchased stop loss protection coverage for the remaining portion of the business. In 2020, AFG expects to reinsure 50% of the premiums not reinsured by the FCIC in the private market.

The balance sheet caption “recoverables from reinsurers” included approximately $109 million on paid losses and LAE and $3.02 billion on unpaid losses and LAE at December 31, 2019. These amounts are net of allowances of approximately $18 million for doubtful collection of reinsurance recoverables. The collectibility of a reinsurance balance is based upon the financial condition of a reinsurer as well as individual claim considerations.

Reinsurance premiums ceded and assumed are presented in the following table (in millions):

	2019		2018		2017
Reinsurance ceded	$	1,957	$	1,817	$	1,751
Reinsurance ceded, excluding crop	1,371		1,202		1,076
Reinsurance assumed — including involuntary pools and associations	255		214		192

Loss and Loss Adjustment Expense Reserves

The consolidated financial statements include the estimated liability for unpaid losses and LAE of AFG’s insurance subsidiaries. This liability represents estimates of the ultimate net cost of all unpaid losses and LAE and is determined by using case-basis evaluations, actuarial projections and management’s judgment. These estimates are subject to the effects of changes in claim amounts and frequency and are periodically reviewed and adjusted as additional information becomes known. In accordance with industry practices, such adjustments are reflected in current year operations. Generally, reserves for reinsurance assumed and involuntary pools and associations are reflected in AFG’s results at the amounts reported by those entities. See Note P — “Insurance — Property and Casualty Insurance Reserves” to the financial statements for information on the development of AFG’s liability for unpaid losses and loss adjustment expenses by accident year as well as a progression of the liability on a GAAP basis over the past three years.

A reconciliation of the liability for losses and LAE reported in the annual statements filed with the state insurance departments in accordance with statutory accounting principles (“SAP”) to the liability reported in the accompanying consolidated financial statements in accordance with GAAP at December 31, 2019 follows (in millions):

Liability reported on a SAP basis, net of $131 million of retroactive reinsurance	$	6,539
Reinsurance recoverables, net of allowance	3,024
Other, including reserves of foreign insurers	669
Liability reported on a GAAP basis	$	10,232

Asbestos and Environmental-related (“A&E”) Insurance Reserves   AFG’s property and casualty group, like many others in the industry, has A&E claims arising in most cases from general liability policies written more than thirty years ago. The establishment of reserves for such A&E claims presents unique and difficult challenges and is subject to uncertainties significantly greater than those presented by other types of claims. For a discussion of these uncertainties, see Item 7 — Management’s Discussion and Analysis of Financial Condition and Results of Operations — “Uncertainties — Asbestos and Environmental-related (“A&E”) Insurance Reserves” and Note N — “Contingencies” to the financial statements.

The following table (in millions) is a progression of the property and casualty group’s A&E reserves.

	2019			2018			2017
Reserves at beginning of year	$	395		$	403		$	337
Incurred losses and LAE	18			18			89
Paid losses and LAE	(30		)	(26		)	(23		)
Reserves at end of year, net of reinsurance recoverable	383			395			403

Gross reserves at end of year	$	529		$	524		$	528

In addition to its ongoing internal monitoring of asbestos and environmental exposures, AFG has periodically conducted comprehensive external studies of its asbestos and environmental reserves relating to the run-off operations of its property and casualty insurance segment and exposures related to its former railroad and manufacturing operations with the aid of specialty actuarial, engineering and consulting firms and outside counsel, with an in-depth internal review during the intervening years. AFG has historically conducted an external study every two years. The most recent external study was in the third quarter of 2017, and AFG is currently evaluating the frequency of future external studies.

An in-depth internal review of AFG’s A&E reserves was completed in the third quarter of 2019 by AFG’s internal A&E claims specialists in consultation with specialty outside counsel and an outside consultant. As a result of the review, AFG’s property and casualty insurance segment recorded an $18 million pretax special charge to increase its asbestos reserves by $3 million (net of reinsurance) and its environmental reserves by $15 million (net of reinsurance). Over the past few years, the focus of AFG’s asbestos claims litigation has shifted to smaller companies and companies with ancillary exposures. AFG’s insureds with these exposures have been the driver of the property and casualty segment’s asbestos reserve increases in recent years. AFG is seeing modestly increasing estimates for indemnity and defense compared to prior studies on certain specific open claims.

The increase in property and casualty environmental reserves in 2019 (as well as in 2018 and 2017) was primarily associated with updated estimates of site investigation and remedial costs with respect to existing sites and newly identified sites. AFG has updated its view of legal defense costs on open environmental claims as well as a number of claims and sites where the estimated investigation and remediation costs have increased. As in past years, there were no new or emerging broad industry trends that were identified in this review.

As a result of the in-depth internal review of AFG’s A&E reserves completed in the third quarter of 2018, AFG’s property and casualty insurance segment recorded an $18 million pretax special charge to increase its asbestos reserves by $6 million (net of reinsurance) and its environmental reserves by $12 million (net of reinsurance).

As a result of the comprehensive external study completed in the third quarter of 2017, AFG’s property and casualty insurance segment recorded an $89 million pretax special charge to increase its asbestos reserves by $53 million (net of reinsurance) and its environmental reserves by $36 million (net of reinsurance).

Marketing

The property and casualty insurance group directs its sales efforts primarily through independent insurance agents and brokers, although small portions are written through employee agents. Independent agents and brokers generally receive a commission on the sale of each policy. Some agents and brokers are eligible for a bonus commission based on the overall profitability of policies placed with AFG by the broker or agent in a particular year. The property and casualty insurance group writes insurance through several thousand agents and brokers.

Competition

AFG’s property and casualty insurance businesses compete with other individual insurers, state funds and insurance groups of varying sizes, some of which are mutual insurance companies possessing competitive advantages in that all their profits inure to their policyholders. See Item 1A — Risk Factors. AFG also competes with self-insurance plans, captive programs and risk retention groups. Due to the specialty nature of these coverages, competition is based primarily on service to policyholders and agents, specific characteristics of products offered and reputation for claims handling. Financial strength ratings, price, commissions and profit-sharing terms are also important factors. Management believes that sophisticated data analysis for refinement of risk profiles, extensive specialized knowledge and loss prevention service have helped AFG compete successfully.

Annuity Segment

General

AFG’s annuity business is focused on the sale of fixed and indexed annuities in the retail, financial institutions, broker-dealer and registered investment advisor markets through independent producers and through direct relationships with certain financial institutions. The Company has a long history in the annuities industry, long-term agent relationships and a reputation for simple, consumer-friendly products. Disciplined product management and operations have enabled AFG to maintain a consistent crediting rate strategy and low-cost structure. AFG’s annuity products are designed to be simple and easy to understand. Lower upfront commissions and bonuses as compared to many competitors allows the Company to pay higher annual crediting rates. In the current low interest rate environment, management is focused on earning the appropriate returns on AFG’s products rather than growing premiums. The annuity operations had approximately 600 employees at December 31, 2019.

Annuity Segment Overview

(*) Market rankings through September 30, 2019, as reported by LIMRA for deferred annuities.

14

As highlighted in the table below, AFG’s annuity business has achieved double digit compounded annual growth rates (“CAGR”) and more than tripled core earnings, premiums and assets over the last ten years. At the same time, management has successfully reduced costs per policy and significantly improved return on equity for the annuity segment.

Growth in Annuity Earnings, Premiums and Assets

AFG’s annuity operations are conducted primarily through the subsidiaries listed in the following table, which includes 2019 statutory annuity premiums (in millions), annuity policies in force and independent ratings.

			Annuity
	Annuity		Policies	Ratings
Company	Premiums		In Force	AM Best	S&P
Great American Life Insurance Company	$	4,799	436,000	A	A+
Annuity Investors Life Insurance Company	161		107,000	A	A+

AFG believes that the ratings assigned by independent insurance rating agencies are an important competitive factor because agents, potential policyholders and financial institutions often use a company’s rating as an initial screening device in considering annuity products. AFG believes that a rating in the “A” category by at least one rating agency is necessary to successfully compete in its primary annuity markets.

15

Due to the deposit-type nature of annuities, annuity premiums received and benefit payments are recorded as increases or decreases in the annuity benefits accumulated liability rather than as revenue and expense under GAAP. Statutory premiums of AFG’s annuity operations for the last three years were as follows (in millions):

	Statutory Premiums
	2019		2018		2017
Financial institutions single premium annuities — indexed	$	1,537	$	1,776	$	1,711
Financial institutions single premium annuities — fixed	1,229		492		622
Retail single premium annuities — indexed	943		1,418		990
Retail single premium annuities — fixed	120		87		70
Broker dealer single premium annuities — indexed	657		1,271		733
Broker dealer single premium annuities — fixed	32		14		7
Pension risk transfer	257		132		6
Education market — fixed and indexed annuities	164		192		174
Total fixed annuity premiums	4,939		5,382		4,313
Variable annuities	21		25		28
Total annuity premiums	$	4,960	$	5,407	$	4,341

Annuities are long-term retirement saving instruments that benefit from income accruing on a tax-deferred basis. The issuer of the annuity collects premiums, credits interest or earnings on the policy and pays out a benefit upon death, surrender or annuitization. Single premium annuities are generally issued in exchange for a one-time, lump-sum premium payment. Certain annuities, primarily in the education market, have premium payments that are flexible in both amount and timing as determined by the policyholder and are generally made through payroll deductions.

Annuity contracts are generally classified as either fixed rate (including indexed) or variable. With a traditional fixed rate annuity, AFG seeks to maintain a desired spread between the yield on its investment portfolio and the rate it credits to policyholders. AFG accomplishes this by: (i) offering crediting rates that it has the option to change after any initial guarantee period (subject to minimum interest rate and other contractual guarantees); (ii) designing annuity products that encourage persistency; and (iii) maintaining an appropriate matching of the duration of assets and liabilities.

An indexed annuity provides policyholders with the opportunity to receive a crediting rate tied, in part, to the performance of an existing stock market or other financial index (generally the S&P 500) or other external rate, price, or unit value (an “index”). A fixed-indexed annuity protects against the related downside risk through a guarantee of principal (excluding

16

surrender charges, market value adjustments, and certain benefit charges). In 2018, AFG began offering variable-indexed annuities, which are similar to fixed-indexed annuities except that the product offers greater upside participation in the selected index as compared to a fixed-indexed annuity and replaces the guarantee of principal in a fixed-indexed annuity with a guaranteed maximum loss. AFG purchases and sells call and put options designed to substantially offset the effect of the index participation in the liabilities associated with indexed annuities.

As an accommodation in its education market, AFG offers a limited amount of variable annuities. With a variable annuity, the earnings credited to the policy vary based on the investment results of the underlying investment options chosen by the policyholder, generally without any guarantee of principal except in the case of death of the insured. Premiums directed to the underlying investment options maintained in separate accounts are invested in funds managed by various independent investment managers. AFG earns a fee on amounts deposited into separate accounts. Subject to contractual provisions, policyholders may also choose to direct all or a portion of their premiums to various fixed-rate options, in which case AFG earns a spread on amounts deposited.

The profitability of a fixed annuity business is largely dependent on the ability of a company to earn income on the assets supporting the business in excess of the amounts credited to policyholder accounts plus expenses incurred (earning a “spread”). Performance measures such as net spread earned are often presented by annuity businesses to help users of their financial statements better understand the company’s performance. The following table shows the earnings before income taxes, as well as the net spread earned on fixed annuities, for the annuity segment both before and after the impact of unlocking, changes in the fair value of derivatives and other impacts of the changes in the stock market and interest rates on annuity segment results (dollars in millions):

	Year ended December 31,
	2019			2018			2017
Annuity earnings before income taxes — before the impact of unlocking, derivatives related to FIAs and other impacts of stock market performance and interest rates on FIAs	$	409		$	409		$	388

Net spread earned on fixed annuities — before impact of unlocking, changes in the fair value of derivatives related to FIAs and other impacts of changes in the stock market and interest rates on FIAs	1.08		%	1.20		%	1.25		%
Changes in fair value of derivatives related to FIAs and other impacts of the stock market and interest rates under (over) option costs	(0.12		%)	(0.04		%)	(0.01		%)
Unlocking	—		%	(0.09		%)	(0.01		%)
Net spread earned on fixed annuities	0.96		%	1.07		%	1.23		%

(a) FIAs provide policyholders with a crediting rate tied, in part, to the performance of an existing stock market or other financial index. AFG attempts to mitigate the risk in the index-based component of these products through the purchase and sale of call and put options on the appropriate index. AFG’s strategy is designed so that the net change in the fair value of the call option assets and put option liabilities will generally offset the economic change in the net liability from the index participation. Both the index-based component of the annuities (an embedded derivative with a fair value of $3.73 billion at December 31, 2019) and the related call and put options (net fair value of $923 million at December 31, 2019) are considered derivatives that must be adjusted for changes in fair value through earnings each period. The fair values of these derivatives are impacted by actual and expected stock market performance and interest rates as well as other factors. Fluctuations in certain of these factors, such as changes in interest rates and the performance of the stock market, are not economic in nature for the current reporting period, but rather impact the timing of reported results.

Marketing

AFG sells its single premium annuities, excluding financial institution production (discussed below), primarily through a retail network of approximately 60 national marketing organizations (“NMOs”) and managing general agents (“MGAs”) who, in turn, direct approximately 1,000 actively producing agents.

AFG also sells single premium annuities in financial institutions through direct relationships with certain financial institutions and through independent agents and brokers. The table below highlights the percentage of AFG’s total annuity premiums generated through its top five financial institution relationships (ranked based on 2019 statutory premiums):

	2019		2018		2017
Wells Fargo & Company	12.0	%	7.4	%	8.1	%
The PNC Financial Services Group, Inc.	8.8	%	6.6	%	9.1	%
Regions Financial Corporation	6.7	%	4.8	%	6.5	%
BB&T Corporation	5.1	%	3.7	%	5.5	%
LPL Financial	4.4	%	4.8	%	5.5	%

In the education market, schools may allow employees to save for retirement through contributions made on a before-tax basis. Federal income taxes are not payable on pretax contributions or earnings until amounts are withdrawn. AFG sells its education market annuities through regional and national agencies.

AFG is licensed to sell its fixed annuity products in all states except New York; it is licensed to sell its variable annuity products in all states except New York and Vermont. At December 31, 2019, AFG had approximately 544,000 annuity policies in force. The states that accounted for 5% or more of AFG’s statutory annuity premiums in 2019 and the comparable preceding years are shown below:

	2019		2018		2017
California	9.9	%	10.2	%	10.0	%
Florida	8.3	%	8.1	%	7.3	%
North Carolina	6.0	%	4.5	%	4.8	%
Ohio	5.9	%	5.2	%	5.4	%
Pennsylvania	5.2	%	5.5	%	6.1	%

Competition

AFG’s annuity businesses operate in highly competitive markets. They compete with other insurers and financial institutions based on many factors, including: (i) ratings; (ii) financial strength; (iii) reputation; (iv) service to policyholders and agents; (v) product design (including interest rates credited, bonus features and index participation); and (vi) commissions. Since most policies are marketed and distributed through independent agents, the insurance companies must also compete for agents.

No single insurer dominates the markets in which AFG’s annuity businesses compete. See Item 1A — Risk Factors. AFG’s competitors include (i) individual insurers and insurance groups, (ii) mutual funds and (iii) other financial institutions. In a broader sense, AFG’s annuity businesses compete for retirement savings with a variety of financial institutions offering a full range of financial services. In the financial institution annuity market, AFG’s annuities compete directly against competitors’ annuities, certificates of deposit and other investment alternatives at the point of sale. In addition, over the last few years, several offshore and/or hedge fund companies have made significant acquisitions of annuity businesses, resulting in annuity groups that are larger in size than AFG’s annuity business.

Sales of annuities, including renewal premiums, are affected by many factors, including: (i) competitive annuity products and rates; (ii) the general level and volatility of interest rates, including the slope of the yield curve; (iii) the favorable tax treatment of annuities; (iv) commissions paid to agents; (v) services offered; (vi) ratings from independent insurance rating agencies; (vii) other alternative investments; (viii) performance and volatility of the equity markets; (ix) media coverage of annuities; (x) regulatory developments regarding suitability and the sales process; and (xi) general economic conditions.

Other Operations

AFG ceased new sales of long-term care insurance in January 2010 and sold substantially all of its run-off long-term care business in December 2015. The legal entities sold in 2015, United Teacher Associates Insurance Company and Continental General Insurance Company, contained substantially all of AFG’s long-term care insurance reserves (96% as measured by net statutory reserves as of November 30, 2015), as well as smaller blocks of annuity and life insurance

18

business. Renewal premiums on the remaining small block of long-term care policies (which are guaranteed renewable) covering approximately 1,500 lives will be accepted unless those policies lapse. At December 31, 2019, AFG’s long-term care insurance reserves were $46 million, net of reinsurance recoverables and excluding the impact of unrealized gains on securities.

Although AFG no longer actively markets new life insurance products, it continues to service and receive renewal premiums on its in-force block of approximately 88,000 policies and $9.53 billion gross ($3.30 billion net of reinsurance) of life insurance in force at December 31, 2019. Renewal premiums, net of reinsurance, were $22 million in 2019, $21 million in 2018 and $17 million in 2017. At December 31, 2019, AFG’s life insurance reserves were $282 million, net of reinsurance recoverables.

Through subsidiaries, AFG is engaged in a variety of other operations, including commercial real estate operations in Cincinnati (office buildings), Whitefield, New Hampshire (Mountain View Grand Resort), Chesapeake Bay (Skipjack Cove Yachting Resort and Bay Bridge Marina), Charleston (Charleston Harbor Resort and Marina) and Palm Beach (Sailfish Marina and Resort). These operations employed approximately 300 full-time employees at December 31, 2019.

Investment Portfolio

General

AFG’s in-house team of investment professionals have followed a consistent strategy over many years and changing economic conditions. Management believes that AFG’s investment expertise has been the driver of consistently strong investment results and effective portfolio risk management over many years. The allocation of AFG’s $55.25 billion investment portfolio at December 31, 2019 is shown below.

Investment Portfolio

For additional information on AFG’s investments, see Note E — “Investments” to the financial statements and Item 7 — Management’s Discussion and Analysis of Financial Condition and Results of Operations — “Investments.” AFG’s earned yield (net investment income divided by average invested assets) on fixed maturities was 4.4% for 2019, 2018 and 2017.

The table below compares total returns, which include changes in fair value, on AFG’s fixed maturities and common stocks and equivalents to comparable public indices. While there are no directly comparable indices to AFG’s portfolio, the two shown below are widely used benchmarks in the financial services industry.

	2019		2018		2017
Total return on AFG’s fixed maturities	8.7	%	1.3	%	5.9	%

The National Association of Insurance Commissioners (“NAIC”) has retained third-party investment management firms to assist in the determination of appropriate NAIC designations for mortgage-backed securities (“MBS”) based not only on the probability of loss (which is the primary basis of ratings by the major ratings firms), but also on the severity of loss and statutory carrying value. Approximately 9% of AFG’s fixed maturity investments are MBS. At December 31, 2019, 98% (based on statutory carrying value of $44.48 billion) of AFG’s fixed maturity investments held by its insurance companies had an NAIC designation of 1 or 2 (the highest of the six designations).

Regulation

AFG’s insurance company subsidiaries are subject to regulation in the jurisdictions where they do business. In general, the insurance laws of the various states establish regulatory agencies with broad administrative powers governing, among other things, premium rates, solvency standards, licensing of insurers, agents and brokers, trade practices, forms of policies, maintenance of specified reserves and capital for the protection of policyholders, deposits of securities for the benefit of policyholders, investment activities and relationships between insurance subsidiaries and their parents and affiliates. Material transactions between insurance subsidiaries and their parents and affiliates generally must receive prior approval of the applicable insurance regulatory authorities and be disclosed. In addition, while differing from state to state, these regulations typically restrict the maximum amount of dividends that may be paid by an insurer to its shareholders in any twelve-month period without advance regulatory approval. Such limitations are generally based on net earnings or statutory surplus. Under applicable restrictions, the maximum amount of dividends available to AFG in 2020 from its insurance subsidiaries without seeking regulatory approval is approximately $852 million.

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (“Dodd-Frank Act”), among other things, established a Federal Insurance Office (“FIO”) within the U.S. Treasury. Under this law, regulations will need to be created for the FIO to carry out its mandate to focus on systemic risk oversight. Since its formation, the FIO has worked with the NAIC and other stakeholders to explore a hybrid approach to regulation of the insurance industry; however, the state-based system of regulation has largely been retained. AFG cannot predict the future role of the FIO and its role in regulation of the insurance industry and how that might ultimately affect AFG’s operations.

Neon, AFG’s UK-based Lloyd’s insurer, is subject to regulation by Lloyd’s, including the establishment of capital requirements and approval of business plans, and the Prudential Regulation Authority.

Most states have created insurance guaranty associations that assess solvent insurers to pay claims of insurance companies that become insolvent. Annual guaranty assessments for AFG’s insurance companies have not been material.

Item 1A. Risk Factors

In addition to the other information set forth in this report, particularly information under “Forward-Looking Statements” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” the following factors could materially affect AFG’s business, financial condition, cash flows or future results. Any one of these factors could cause AFG’s actual results to vary materially from recent results or from anticipated future results. The risks described below are not the only risks facing AFG. Additional risks and uncertainties not currently known to management or that management currently deems to be immaterial also may materially adversely affect AFG’s business, financial condition and/or operating results.

Adverse developments in the financial markets and deterioration in global economic conditions could have a material adverse effect on AFG’s results of operations and financial condition.

Worldwide financial markets have, from time to time, experienced significant and unpredictable disruption. A prolonged economic downturn would result in heightened credit risk, reduced valuation of certain investments and decreased economic activity.

Changes in financial markets including fluctuations in interest rates, credit conditions, equity prices and many other factors that are unpredictable and beyond AFG’s control, like the impact of Brexit or the imposition of tariffs by the U.S. and by other countries in response, can adversely affect the value of investments and the realization of investment income.

A significant majority of AFG’s investment portfolio consists of fixed maturity investments, and changes in global economic conditions, including interest rates, could have a material adverse effect on AFG’s results of operations and financial condition.

As of December 31, 2019, approximately 84% of AFG’s investment portfolio holdings consisted of fixed maturity investments that are sensitive to changes in interest rates. A decline in interest rates may reduce the returns earned on new and floating-rate fixed maturity investments, thereby reducing AFG’s net investment income, while an increase in interest rates may reduce the value of AFG’s existing fixed maturity investments, which primarily have fixed interest rates. The value of AFG’s fixed maturity investments is also subject to credit risk as certain investments may default or become impaired due to deterioration in the financial condition of issuers of those investments. If a decline in the fair value of a specific investment (below its amortized cost) is considered to be other-than-temporary, a provision for impairment would be charged to earnings.

Interest rates have remained at historical lows for an extended period. In addition, central banks in some countries have pursued largely unprecedented negative interest rate policies in recent years, the consequences of which are uncertain. The continuation of the current low interest rate environment or a deflationary environment with negative interest rates could affect business behavior in ways that are adverse to AFG and could constrict AFG’s net investment income.

As of December 31, 2019, mortgage-backed securities constituted approximately 9% of AFG’s fixed maturity portfolio. In addition to the risks applicable to the entire fixed maturity investment portfolio, changes in interest rates can expose AFG to prepayment risks on mortgage-backed securities. In periods of declining interest rates, mortgage prepayments generally increase and mortgage-backed securities are paid down more quickly, requiring AFG to reinvest the proceeds at the then current market rates, which may be lower than on the securities repaid.

Changes in interest rates could adversely affect AFG’s results of operations.

The profitability of AFG’s annuity segment is largely dependent on the spread between what it earns on its investments and the crediting rate it pays on its annuity contracts plus expenses incurred.

Both rising and declining interest rates can negatively affect AFG’s annuity results. Most of AFG’s annuity products have guaranteed minimum crediting rates. Although AFG could reduce the average crediting rate on a substantial portion of its traditional fixed and indexed annuities during periods of low or falling interest rates, AFG may not be able to fully offset the decline in investment earnings with lower crediting rates.

During periods of rising interest rates, AFG may experience competitive pressure to increase crediting rates to avoid a decline in sales or increased surrenders, thus resulting in lower spreads. In addition, an increase in surrenders could require the sale of investments at a time when the prices of those assets are lower due to the increase in market rates, which may result in realized investment losses.

21

Intense competition could adversely affect AFG’s results of operations.

The property and casualty insurance segment operates in a highly competitive industry that is affected by many factors that can cause significant fluctuations in its results of operations. The lines of business in this segment compete with other individual insurers, state funds and insurance groups of varying sizes, some of which are mutual insurance companies possessing competitive advantages in that all their profits inure to their policyholders. In addition, certain foreign insurers may be taxed at lower rates, which may result in a competitive advantage over AFG. The property and casualty insurance segment also competes with self-insurance plans, captive programs and risk retention groups. Competition is based on many factors, including service to policyholders and agents, product design, reputation for claims handling, price, commissions, ratings and financial strength. Peer companies and competitors in some or all of AFG’s specialty lines include the following companies and/or their subsidiaries: Alleghany Corp., American International Group Inc., American National Insurance Company, AmTrust Financial Services, Inc., Arch Capital Group Ltd., Assurant, Inc., Chubb Ltd., Cincinnati Financial Corp., CNA Financial Corp., Fairfax Financial Holdings Ltd. (Zenith National), The Hartford Financial Services Group, Inc., Lancer Insurance Company, Liberty Mutual, Markel Corp., Munich Re Group (American Modern Insurance), Protective Insurance Company, RLI Corp., The Travelers Companies, Inc., Tokio Marine Holdings, Inc. (HCC Insurance, Philadelphia Consolidated), W.R. Berkley Corp., AXA (XL Group Ltd.) and Zurich Insurance Group Ltd.

AFG’s annuity segment competes with individual insurers and insurance groups, mutual funds and other financial institutions. In addition, in recent years, offshore and/or hedge fund companies have made significant acquisitions of annuity businesses. Competition is based on numerous factors including reputation, product design, interest crediting rates, performance, scope of distribution, price and perceived financial strength and credit ratings. Peer companies and competitors for AFG’s annuity segment include the following companies and/or their subsidiaries: Allianz Life Insurance Company of North America, American Equity Investment Life Holding Company (Eagle Life Insurance Company), American International Group Inc., Athene Holding Ltd, Global Atlantic Financial Group Ltd. (Forethought Life Insurance Company), Lincoln National Corp., MetLife, Inc., Nationwide Mutual Insurance Company, Pacific Life Insurance Company and Sumitomo Life Insurance Company (Symetra Financial Corp.).

Some of AFG’s competitors have more capital and greater resources than AFG and may offer a broader range of products and lower prices than AFG offers. If competition limits AFG’s ability to write new or renewal business at adequate rates, its results of operations will be adversely affected.

A significant percentage of AFG’s sales of annuity products through financial institutions is concentrated in a small number of institutions.

Annuity premiums generated through financial institutions represented 56% of AFG’s annuity premiums in 2019. In 2019, two large financial institutions accounted for 37% of AFG’s total sales through financial institutions and 21% of AFG’s overall annuity sales. In the financial institutions annuity market, AFG competes directly against competitors’ annuities, certificates of deposit and other investment alternatives at the point of sale. Loss of a substantial portion of this business coupled with a failure to replace these financial institutions if they significantly reduce sales of AFG annuities could reduce AFG’s future growth.

AFG’s revenues could be adversely affected if it is not able to attract and retain independent agents.

AFG’s reliance on the independent agency market makes it vulnerable to a reduction in the amount of business written by agents. Many of AFG’s competitors also rely significantly on the independent agency market. Some of AFG’s competitors offer a wider variety of products, lower prices for insurance coverage or higher commissions. A reduction in the number of independent agencies marketing AFG’s products, the failure of agencies to successfully market AFG’s products, changes in the strategy or operations of agencies (including agency consolidation) or the choice of agencies to reduce their writings of AFG products could adversely affect AFG’s revenues and profitability.

The inability to obtain reinsurance or to collect on ceded reinsurance could adversely affect AFG’s results of operations.

AFG purchases reinsurance to limit the amount of risk it retains. Market conditions determine the availability and cost of the reinsurance protection AFG purchases, which affects the level of AFG’s business and profitability, as well as the level and types of risk AFG retains. If AFG is unable to obtain sufficient reinsurance at a cost AFG deems acceptable, AFG may opt to reduce the volume of its underwriting. AFG is also subject to credit risk with respect to its reinsurers, as AFG will remain liable to its insureds regardless of whether a reinsurer is able to meet its obligations under agreements covering the reinsurance ceded. The collectability of recoverables from reinsurers is subject to uncertainty arising from a number of factors, including a reinsurers’ financial capacity and willingness to make payments under the terms of a reinsurance treaty or contract and changes in market conditions. As of December 31, 2019, AFG has $3.42 billion of recoverables from reinsurers on its balance sheet.

22

AFG is subject to comprehensive regulation, and its ability to earn profits may be restricted by these regulations.

AFG is subject to comprehensive regulation by government agencies in the states and countries where its insurance company subsidiaries are domiciled and where these subsidiaries issue policies and handle claims. In addition, the Lloyd’s marketplace sets rules under which its members operate, including Neon (AFG’s Lloyd’s syndicate, which has been placed into run-off by AFG). Most insurance regulations are designed to protect the interests of AFG’s policyholders and third-party claimants as opposed to its investors.

The Dodd-Frank Act, enacted in June 2010, mandates changes to the regulation of the financial services industry. Legislative or regulatory requirements imposed by or promulgated in connection with the Dodd-Frank Act may impact AFG in many ways, including, but not limited to: placing AFG at a competitive disadvantage relative to its competition or other financial services entities; changing the competitive landscape of the financial services sector or the insurance industry; making it more expensive for AFG to conduct its business; and otherwise having a material adverse effect on the overall business climate as well as AFG’s financial condition and results of operations.

Changes in domestic or foreign tax laws or interpretations of such laws could increase AFG’s corporate taxes and reduce earnings. For example, on December 22, 2017, the U.S. enacted The Tax Cuts and Jobs Act of 2017 (“TCJA”), which significantly reformed the U.S. tax code. Amendments or clarifications of the TCJA from additional regulatory and administrative guidance, may occur. Any changes in federal income tax laws, including changes to the TCJA, could adversely affect the federal income taxation of AFG’s ongoing operations and have a material adverse impact on its financial condition and results of operations.

As a participant in the federal crop insurance program, AFG could also be impacted by regulatory and legislative changes affecting that program. For example, the reinsurance levels that the federal government provides to authorized carriers could be reduced by future legislation. AFG will continue to monitor new and changing federal regulations and the potential impact, if any, on its insurance company subsidiaries.

On June 5, 2019, the U.S. Securities and Exchange Commission adopted a package of regulatory proposals to enhance standards of conduct owed by broker-dealers to their clients known as Regulation Best Interest. The new rule heightens the standards that registered representatives need to meet when making a recommendation by requiring them to act in the best interest of the retail customer at the time of the recommendation. Regulation Best Interest requires a registered representative to (i) disclose to the customer the material facts relating to scope and terms of the relationship, (ii) exercise reasonable diligence, care, skill and prudence in recommending a product that is in the customer’s best interest, and (iii) eliminate or, at a minimum, disclose, material conflicts of interests.

Existing insurance-related laws and regulations may become more restrictive in the future or new restrictive laws may be enacted; it is not possible to predict the potential effects of these laws and regulations. The costs of compliance or the failure to comply with existing or future regulations could impose significant burdens on AFG.

A downgrade or potential downgrade in AFG’s financial strength and/or credit ratings by one or more rating agencies could adversely affect its business, financial condition, results of operations and/or cash flows.

Financial strength ratings are an important factor in establishing the competitive position of insurance companies and may have an effect on an insurance company’s sales. A downgrade out of the “A” category in AFG’s insurers’ claims-paying and financial strength ratings could significantly reduce AFG’s business volumes in certain lines of business, adversely impact AFG’s ability to access the capital markets and increase AFG’s borrowing costs.

In addition to the financial strength ratings of AFG’s principal insurance company subsidiaries, various rating agencies also publish credit ratings for AFG. Credit ratings are indicators of a debt issuer’s ability to meet the terms of debt obligations in a timely manner, are part of AFG’s overall financial profile and affect AFG’s ability to access certain types of capital. A downgrade in AFG’s credit ratings could have a material adverse effect on AFG’s financial condition and results of operations and cash flows in a number of ways, including adversely limiting access to capital markets, potentially increasing the cost of debt or increasing borrowing costs under AFG’s current revolving credit facility.

The continued threat of terrorism and ongoing military and other actions, as well as civil unrest, may adversely affect AFG’s results of operations.

The occurrence of one or more terrorist attacks could cause significant losses from insurance claims that could adversely affect AFG’s profitability. Private sector catastrophe reinsurance is limited and generally unavailable for terrorism losses caused by attacks with nuclear, biological, chemical or radiological weapons. Reinsurance coverage from the federal government under the Terrorism Risk Insurance Program Reauthorization Act of 2015 (“TRIPRA”) is also limited. Although

23

TRIPRA provides benefits for certified acts of terrorism that exceed a certain threshold of industry losses ($180 million in 2019, increasing by $20 million to $200 million by 2020), those benefits are subject to a deductible and other limitations. In 2020, AFG would have to sustain losses from terrorism of nearly $750 million to be eligible for reinsurance under the program. In addition, because the interpretation of this law is untested, there is substantial uncertainty as to how it will be applied to specific circumstances. Finally, the program currently expires at the end of 2020, and the elimination or modification of the program, or a failure to extend the program, could adversely affect AFG’s property and casualty insurance business through increased exposure to a catastrophic level of terrorism losses.

AFG may experience difficulties with technology or data security, which could have an adverse effect on its business or reputation.

AFG uses computer systems and services to store, retrieve, evaluate and utilize company and customer data and information. Systems failures or outages could compromise AFG’s ability to perform business functions in a timely manner, which could harm its ability to conduct business and hurt its relationships with business partners and customers. In the event of a disaster such as a natural catastrophe, an industrial accident, a blackout, a malicious software attack, a terrorist attack or war, AFG’s systems may be inaccessible to employees, customers or business partners for an extended period of time. Even if AFG’s employees are able to report to work, they may be unable to perform their duties for an extended period of time if the Company’s data or systems are disabled or destroyed.

AFG’s computer systems are subject to cyber-attacks, viruses, malware, hackers and other external hazards, as well as inadvertent errors, equipment and system failures and to unauthorized or illegitimate actions by employees, consultants, agents and other persons with legitimate access to AFG’s systems. In addition, over time, the sophistication of these threats continues to increase. AFG’s administrative and technical controls as well as other preventative actions used to reduce the risk of cyber incidents and protect AFG’s information may be insufficient to detect or prevent future unauthorized access, other physical and electronic break-ins, cyber-attacks or other security breaches to AFG’s computer systems or those of third parties with whom AFG does business.

AFG has increasingly outsourced certain technology and business process functions to third parties and may continue to do so in the future. Outsourcing of certain technology and business process functions to third parties may expose AFG to increased risk related to data security or service disruptions. If AFG does not effectively develop, implement and monitor these relationships, third-party providers do not perform as anticipated, technological or other problems are incurred with a transition, or outsourcing relationships relevant to AFG’s business process functions are terminated, AFG may not realize expected productivity improvements or cost efficiencies and may experience operational difficulties, increased costs and a loss of business.

The increased risks identified above could expose AFG to data loss, disruption of service, monetary and reputational damages, competitive disadvantage and significant increases in compliance costs and costs to improve the security and resiliency of AFG’s computer systems. The compromise of personal, confidential or proprietary information could also subject AFG to legal liability or regulatory action under evolving cyber-security, data protection and privacy laws and regulations enacted by the U.S. federal and state governments, Canada, the European Union (the “EU”) or other jurisdictions or by various regulatory organizations or exchanges. As a result, AFG’s ability to conduct business and its results of operations might be materially and adversely affected.

Any failure to appropriately collect, administer and protect consumer information could adversely affect AFG’s reputation, subject AFG to fines, claims and penalties, and have a material adverse effect on AFG’s business, financial condition and results of operations.

AFG and certain of its third-party vendors collect and store sensitive data in the ordinary course of AFG’s business, including personal identification information of its employees and that of its customers, vendors, investors and other third parties. In connection with AFG’s property and casualty insurance operations, data may include medical information. Laws and regulations in this area are evolving at an international, national and state level and are generally becoming more rigorous, including through the adoption of more stringent subject matter-specific laws, like the California Consumer Privacy Act of 2018, the New York Department of Financial Services’ Cybersecurity Regulation and Ohio’s insurance data security law, which regulate the collection and use of data and security and data breach obligations. If any disruption or security breach results in a loss or damage to AFG’s data, or inappropriate disclosure of AFG’s confidential information or that of others, it could damage AFG’s reputation, affect its relationships with customers and clients, lead to claims against AFG, result in regulatory action and harm AFG’s business. In addition, AFG may be required to incur significant costs to mitigate the damage caused by any security breach or to protect against future damage.

24

AFG’s property and casualty reserves may be inadequate, which could have a material adverse effect on AFG’s results of operations.

Liabilities for unpaid losses and loss adjustment expenses (“LAE”) do not represent an exact calculation of liability but instead represent management estimates of what the ultimate settlement and administration of claims will cost, supported by actuarial expertise and projection techniques, at a given accounting date. The process of estimating unpaid losses and LAE reserves involves a high degree of judgment and is subject to a number of variables. These variables can be affected by both internal and external events, such as: changes in claims handling procedures, adverse changes in loss cost trends (including inflationary pressures on medical costs), economic conditions (including general inflation), legal trends and legislative changes, and varying judgments and viewpoints of the individuals involved in the estimation process, among others. The impact of many of these items on ultimate costs for unpaid losses and LAE is difficult to estimate. Unpaid losses and LAE reserve estimation difficulties also differ significantly by product line due to differences in claim complexity, the volume of claims, the potential severity of individual claims, the determination of an occurrence date for a claim and lags in the time between damage, loss or injury and when a claim is actually reported to the insurer. In addition, the historic development of AFG’s liability for unpaid losses and LAE may not necessarily reflect future trends in the development of these amounts. Accordingly, it is not appropriate to extrapolate future redundancies or deficiencies based on historical information. To the extent that reserves are inadequate and are strengthened, AFG’s profitability would be adversely affected because the amount of any such increase would be treated as a charge to earnings in the period in which the deficiency is recognized.

AFG’s results of operations could be adversely impacted by severe weather conditions, climate change or catastrophes, both natural and man-made.

Catastrophes can be caused by unpredictable natural events such as hurricanes, windstorms, severe storms, tornadoes, floods, hailstorms, severe winter weather, earthquakes, explosions and fire, and by man-made events, such as terrorist attacks. While not considered a catastrophe by insurance industry standards, droughts can have a significant adverse impact on AFG’s crop insurance results. In addition, extreme weather events that are linked to rising temperatures, changing global weather patterns and fluctuating rain, snow and sea levels (climate change) could result in increased occurrence and severity of catastrophes. The extent of gross losses from a catastrophe event is a function of both the total amount of insured exposure in the area affected by the event and the severity of the event, potentially mitigated by any reinsurance coverage purchased by AFG’s insurance subsidiaries. In addition, certain catastrophes could result in both property and non-property claims from the same event. A severe catastrophe or a series of catastrophes could result in losses exceeding AFG’s reinsurance protection and may have a material adverse impact on its results of operations or financial condition.

Volatility in crop prices, as a result of weather conditions, climate change or otherwise, could adversely impact AFG’s results of operations.

Weather conditions, including too much moisture (flooding or excessive rain) or not enough moisture (droughts), and the level of crop prices in the commodities market heavily impact AFG’s crop insurance business. These factors are inherently unpredictable and could result in significant volatility in the results of the crop insurance business from one year to the next. AFG’s crop results could also be negatively impacted by pests and plant disease. A large decline in the commodity prices of one or more of the major crops that AFG insures could have a material adverse effect on AFG’s results of operations or financial condition.

AFG’s international operations exposes it to investment, political and economic risks, including foreign currency and credit risk.

AFG’s international operations expose AFG to a number of additional risks. These risks include restrictions such as price controls, capital controls, currency exchange limits, ownership limits and other restrictive or anti-competitive governmental actions or requirements, which could have an adverse effect on AFG’s business and reputation. AFG’s business activities outside the United States may also be subject to political and economic risks, including foreign currency and credit risk.

AFG’s business activities outside the United States subject AFG to additional domestic and foreign laws and regulations, including the Foreign Corrupt Practices Act, the UK Bribery Act and similar laws in other countries that prohibit the making of improper payments to foreign officials. Although AFG has policies and controls in place that are designed to ensure compliance with these laws, if those controls are ineffective and an employee or intermediary fails to comply with applicable laws and regulations, AFG could suffer civil and criminal penalties and AFG’s business and reputation could be adversely affected. Some countries have laws and regulations that lack clarity and, even with local expertise and effective controls, it can be difficult to determine the exact requirements of, and potential liability under, the local laws. Failure to comply with local laws in a particular market may result in substantial liability and could have a significant and negative effect not only on AFG’s business in that market but also on AFG’s reputation generally.

25

Exposure to asbestos or environmental claims could materially adversely affect AFG’s results of operations and financial condition.

AFG has asbestos and environmental (“A&E”) exposures arising from its insurance operations and former railroad and manufacturing operations. Uncertainties surrounding the final resolution of these A&E liabilities continue, and it is difficult to estimate AFG’s ultimate exposure to such liabilities and related litigation. Establishing A&E liabilities is subject to uncertainties that are significantly greater than those presented by other types of liabilities. Uncertainties include the long delays between exposure and manifestation of any bodily injury or property damage, difficulty in identifying the source of the asbestos or environmental contamination, long reporting delays, the risks inherent in complex litigation and difficulty in properly allocating liability for the asbestos or environmental damage. As a result, A&E liabilities are subject to revision as new information becomes available and as claims are made and develop. Claimants continue to assert new and novel theories of recovery, and from time to time, there is proposed state and federal legislation regarding A&E liability, which would also affect AFG’s exposure. If AFG has not established adequate reserves to cover future claims, AFG’s results of operations and financial condition could be materially adversely affected.

Ineffective risk management policies in the indexed annuity business could adversely affect AFG’s results of operations.

AFG’s risk management policies and procedures, which are intended to identify, monitor and manage economic risks in its annuity business, may not be fully effective at mitigating risk exposures in all market conditions or against all types of risk. For instance, AFG uses derivatives to alleviate risks related to floating-rate investments as well as annuity products that credit interest or provide a return based, in part, on the change in a referenced index. AFG’s use of derivatives may not accurately counterbalance the actual risk exposure, and any derivatives held may not be sufficient to completely hedge the associated risks. In addition, counterparties may fail to perform under the derivative financial instruments. AFG may also decide not to hedge, or fail to identify, certain risks to which it is exposed. Ultimately, AFG’s use of derivatives and other risk management strategies may be inadequate to protect against the full extent of the exposure or losses AFG seeks to mitigate.

Variations from the actuarial assumptions used to establish certain assets and liabilities in AFG’s annuity business could adversely affect AFG’s results of operations.

The earnings on AFG’s annuity products depend significantly upon the extent to which actual experience is consistent with the assumptions used in setting reserves and establishing and amortizing deferred policy acquisition costs. These assumptions relate to investment yields (and spreads over fixed annuity crediting rates), benefit utilization rates, equity market performance, the cost of options used in the indexed annuity business, mortality, surrenders, annuitizations and other withdrawals. Developing such assumptions is complex and involves information obtained from company-specific and industry-wide data, as well as general economic information. These assumptions, and therefore AFG’s results of operations, could be negatively impacted by changes in any of the factors listed above.

The modification or elimination of the London Inter-Bank Offered Rate may adversely affect AFG’s results of operations.

The modification or elimination of the London Inter-Bank Offered Rate (“LIBOR”), a long-standing benchmark interest rate for floating-rate financial contracts, may adversely affect the interest rates on and fair value of AFG’s floating rate investments, interest rate swaps, Federal Home Loan Bank advances and any other assets or liabilities whose value is tied to LIBOR. In addition, the majority of the assets and liabilities of the collateralized loan obligations that AFG manages and consolidates are tied to LIBOR. On July 27, 2017, the U.K. Financial Conduct Authority, which regulates LIBOR, announced that it has commitments from panel banks to submit rates to LIBOR through the end of 2021 but will no longer persuade or compel banks to submit rates for the calculation of LIBOR after 2021. However, it remains unclear if, how and in what form, LIBOR will continue to exist. Proposals for alternative reference rates for dollars and other currencies have been announced or have already begun publication. Markets are slowly developing in response to these new rates but questions around liquidity in these alternative reference rates and how to appropriately adjust these alternative reference rates to eliminate any economic value transfer at the time of transition persist. At this time, AFG cannot predict the overall effect of the modification or elimination of LIBOR or the establishment of alternative benchmark rates.

Changes to existing accounting standards could adversely impact AFG’s reported results of operations.

As a U.S.-based SEC registrant, AFG prepares its financial statements in accordance with GAAP, as promulgated by the Financial Accounting Standards Board, subject to the accounting-related rules and interpretations of the SEC. Changes in accounting standards, particularly those that specifically apply to insurance company operations, may impact AFG’s reported financial results and could cause increased volatility in reported earnings, resulting in other adverse impacts on AFG’s ratings and cost of capital, and decrease the understandability of AFG’s financial results as well as the comparability of AFG’s reported results with other insurers.

26

As a holding company, AFG is dependent on the operations of its insurance company subsidiaries to meet its obligations and pay future dividends.

AFG is a holding company and a legal entity separate and distinct from its insurance company subsidiaries. As a holding company without significant operations of its own, AFG’s principal sources of funds are dividends and other distributions from its insurance company subsidiaries. State insurance laws differ from state to state but, absent advance regulatory approval, restrict the maximum amount of dividends that may be paid by an insurer to its shareholders in any twelve-month period. AFG’s rights to participate in any distribution of assets of its insurance company subsidiaries are subject to prior claims of policyholders and creditors (except to the extent that its rights, if any, as a creditor are recognized). Consequently, AFG’s ability to pay its debts, expenses and dividends to its shareholders may be limited.

Statutory capital requirements set by the NAIC and the various state insurance regulatory bodies establish regulations that provide minimum capitalization requirements based on risk-based capital (“RBC”) ratios for insurance companies. Statutory surplus and RBC ratios may change in a given year based on a number of factors, including statutory earnings/losses, reserve changes, excess capital held to support growth, equity market and interest rate changes, the value of investment securities, and changes to the RBC formulas. Increases in the amount of capital or reserves that AFG’s larger insurance subsidiaries are required to hold could reduce the amount of future dividends such subsidiaries are able to distribute to the holding company or require capital contributions. Any reduction in the RBC ratios of AFG’s insurance subsidiaries could also adversely affect their financial strength ratings as determined by rating agencies.

Adverse developments in the financial markets may limit AFG’s access to capital.

Financial markets in the U.S. and elsewhere can experience extreme volatility, which exerts downward pressure on stock prices and limits access to the equity and debt markets for certain issuers, including AFG. AFG can borrow up to $500 million under its revolving credit facility, which expires in June 2021. In addition, AFG’s access to funds through this facility is dependent on the ability of its banks to meet their funding commitments. There were no borrowings outstanding under AFG’s bank credit line or any other parent company short-term borrowing arrangements during 2019. If AFG cannot obtain adequate capital or sources of credit on favorable terms, or at all, its business, operating results and financial condition could be adversely affected.

AFG may suffer losses from litigation, which could materially and adversely affect AFG’s financial condition and business operations.

AFG, primarily in its property and casualty insurance operations and historical operations, is involved in litigation. Litigation by nature is unpredictable, and the outcome of any case is uncertain and could result in liabilities that vary from the amounts AFG has currently recorded. Pervasive or significant changes in the judicial environment relating to matters such as trends in the size of jury awards, developments in the law relating to the liability of insurers or tort defendants, and rulings concerning the availability or amount of certain types of damages could cause AFG’s ultimate liabilities to change from current expectations. Changes in federal or state tort litigation laws or other applicable law could have a similar effect. It is not possible to predict changes in the judicial and legislative environment, including in connection with asbestos and environmental claims. AFG’s business, financial condition, results of operations and liquidity could also be adversely affected if judicial or legislative developments cause AFG’s ultimate liabilities to increase from current expectations.

Certain shareholders exercise substantial control over AFG’s affairs, which may impede a change of control transaction.

Carl H. Lindner III and S. Craig Lindner are each Co-Chief Executive Officers and Directors of AFG. Together, Carl H. Lindner III and S. Craig Lindner beneficially own 8.9% of AFG’s outstanding Common Stock as of February 1, 2020. Other members of the Lindner family own, directly or through trusts, a significant number of additional shares of AFG Common Stock. As a result, the Lindner family has the ability to exercise significant influence over AFG’s management and over matters requiring shareholder approval. Such influence could prevent an acquisition of AFG at a price which other shareholders may find attractive.

27

The price of AFG Common Stock may fluctuate significantly, which may make it difficult for holders to resell common stock when they want or at a price they find attractive.

The price of AFG’s Common Stock, which is listed on the NYSE, constantly changes. During 2019, AFG’s Common Stock traded at prices ranging between $88.70 and $111.86. AFG’s Common Stock price can fluctuate as a result of a variety of factors, many of which are beyond its control. These factors include but are not limited to:

• actual or anticipated variations in quarterly operating results;

• actual or anticipated changes in the dividends paid on AFG Common Stock;

• rating agency actions;

• recommendations by securities analysts;

• significant acquisitions or business combinations, strategic partnerships, joint ventures or capital commitments by or involving AFG or its competitors;

• operating and stock price performance of other companies that investors deem comparable to AFG;

• news reports relating to trends, concerns and other issues in AFG’s lines of business;

• general economic conditions, including volatility in the financial markets; and

• geopolitical conditions such as acts or threats of terrorism or military conflicts.

Item 2. Properties

AFG and its insurance subsidiaries lease the majority of their office and storage facilities in numerous cities throughout the United States and internationally, including the Company’s headquarters in Cincinnati, Ohio. Subsidiaries of AFG own several other buildings in downtown Cincinnati. AFG and its affiliates occupy approximately half of the aggregate 645,000 square feet of commercial and office space in these buildings. A property and casualty insurance subsidiary occupies approximately 90% of the 281,000 square feet of rentable office space on 17.5 acres of land that it owns in Richfield, Ohio. See Item 1 — Business — “Other Operations” for a discussion of AFG’s other commercial real estate operations.

Item 3. Legal Proceedings

AFG and its subsidiaries are involved in litigation from time to time, generally arising in the ordinary course of business. This litigation may include, but is not limited to, general commercial disputes, lawsuits brought by policyholders, employment matters, reinsurance collection matters and actions challenging certain business practices of insurance subsidiaries. Except for the following, management believes that none of the litigation meets the threshold for disclosure under this Item.

AFG’s insurance company subsidiaries and its 100%-owned subsidiary, American Premier Underwriters (including its subsidiaries, “American Premier”), are parties to litigation and receive claims alleging injuries and damages from asbestos, environmental and other substances and workplace hazards and have established loss accruals for such potential liabilities. None of such litigation or claims is individually material to AFG; however, the ultimate loss for these claims may vary materially from amounts currently recorded as the conditions surrounding resolution of these claims continue to change.

American Premier is a party or named as a potentially responsible party in a number of proceedings and claims by regulatory agencies and private parties under various environmental protection laws, including the Comprehensive Environmental Response, Compensation and Liability Act, seeking to impose responsibility on American Premier for hazardous waste or discharge remediation costs at certain railroad sites formerly owned by its predecessor, Penn Central Transportation Company (“PCTC”), and at certain other sites where hazardous waste or discharge allegedly generated by PCTC’s railroad operations and American Premier’s former manufacturing operations is present. It is difficult to estimate American Premier’s liability for remediation costs at these sites for a number of reasons, including the number and financial resources of other potentially responsible parties involved at a given site, the varying availability of evidence by which to allocate responsibility among such parties, the wide range of costs for possible remediation alternatives, changing technology and the period of time over which these matters develop. Nevertheless, American Premier believes that its accruals for potential environmental liabilities are adequate to cover the probable amount of such liabilities, based on American Premier’s estimates of remediation costs and related expenses and its estimates of the portions of such costs that will be borne by other parties. Such estimates are based on information currently available to American Premier and are subject to future change as additional information becomes available.

PART II

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

AFG Common Stock is listed and traded on the New York Stock Exchange under the symbol AFG. There were approximately 5,200 shareholders of record of AFG Common Stock at February 1, 2020.

Issuer Purchases of Equity Securities

AFG did not repurchase any shares of its Common Stock in the public markets in 2019. As of December 31, 2019, there were 5,000,000 remaining shares that may be repurchased under the Plans authorized by AFG’s Board of Directors in February 2016 and February 2019.

AFG acquired 47,069 shares of its Common Stock (at an average of $99.07 per share) in the first nine months of 2019, 2,947 shares (at an average of $106.38 per share) in October 2019 and 46 shares (at $109.70 per share) in December 2019 in connection with its stock incentive plans.

(a) AFG’s net earnings per share (diluted), determined in accordance with GAAP, includes certain items that may not be indicative of its ongoing core operations. AFG believes that its core net operating earnings per share provides management, financial analysts, rating agencies and investors with an understanding of the results from the ongoing operations of the Company by excluding the impact of net realized gains and losses and other items that are not necessarily indicative of operating trends. AFG’s management uses core net operating earnings to evaluate financial performance against historical results because it believes this provides a more comparable measure of its continuing business. Core net operating earnings is also used by AFG’s management as a basis for strategic planning and forecasting. Core net operating earnings per share (diluted) is a non-GAAP financial measure. See Item 7 — Management’s Discussion and Analysis — “Results of Operations — General” for additional details, including a reconciliation of core net operating earnings per share (diluted) to net earnings available to shareholders (diluted) computed in accordance with GAAP.

(b) AFG increased its quarterly dividend in October of each of the last five years as follows: increased to $0.45 per share in 2019, $0.40 per share in 2018, $0.35 per share in 2017, $0.3125 per share in 2016 and $0.28 per share in 2015. In addition, AFG paid special cash dividends of $3.30 per share in 2019, $3.00 per share in 2018, $3.50 per share in 2017 and $1.00 per share in 2016 and 2015.

(c) Fixed charges are computed on a “total enterprise” basis. For purposes of calculating the ratios, “earnings” have been computed by adding to pretax earnings the fixed charges and the noncontrolling interests in earnings of subsidiaries having fixed charges and the undistributed equity in earnings or losses of investees. Fixed charges include interest (including annuity benefits as indicated), amortization of debt premium/discount and expense, preferred dividend and distribution requirements of subsidiaries and a portion of rental expense deemed to be representative of the interest factor. The ratio of core earnings to fixed charges excluding annuity benefits and the ratio of earnings to fixed charges excluding and including annuity benefits are shown in the table below:

	2019		2018		2017		2016		2015
Ratio of core earnings to fixed charges excluding annuity benefits	12.78		11.31		8.97		9.15		8.59
Impact of non-core items	1.83		(3.45	)	(1.30	)	(0.53	)	(2.01	)
Ratio of earnings to fixed charges excluding annuity benefits	14.61		7.86		7.67		8.62		6.58
Impact of including interest on annuities as a fixed charge	(12.76	)	(6.32	)	(5.95	)	(6.77	)	(4.92	)
Ratio of earnings to fixed charges including annuity benefits	1.85		1.54		1.72		1.85		1.66

Although the ratio of earnings to fixed charges excluding annuity benefits is not required or encouraged to be disclosed under Securities and Exchange Commission rules, some investors and lenders may not consider interest credited to annuity policyholders’ accounts a borrowing cost for an insurance company, and accordingly, believe this ratio is meaningful.

(d) Net unrealized gains related to fixed maturities, which includes net unrealized gains (losses) on cash flow hedges, is part of accumulated other comprehensive income and is shown net of related adjustments to deferred policy acquisition costs and certain liabilities in the annuity, long-term care and life businesses.

(e) Adjusted shareholders’ equity and adjusted book value per share exclude net unrealized gains related to fixed maturity securities. Management believes that investors find a measurement of shareholders’ equity excluding net unrealized gains related to fixed maturity securities to be meaningful as the unrealized gains related to fixed maturities fluctuates with changes in interest rates in a way that is primarily only meaningful to AFG if it sells those investments.

GENERAL

Following is a discussion and analysis of the financial statements and other statistical data that management believes will enhance the understanding of AFG’s financial condition and results of operations. This discussion should be read in conjunction with the financial statements beginning on page F-1.

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 most of 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.

At December 31, 2019, AFG (parent) held approximately $243 million in cash and securities and had $500 million available under a bank line of credit, which expires in June 2021.

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, and in the sale of traditional fixed and indexed annuities in the retail, financial institutions, broker-dealer and registered investment advisor markets.

AFG reported fourth quarter 2019 net earnings attributable to shareholders of $211 million ($2.31 per share, diluted) compared to a net loss attributable to shareholders of $29 million ($0.33 per share, diluted) in the fourth quarter of 2018, reflecting:

• net realized gains on securities in the fourth quarter of 2019 compared to net realized losses on securities in the fourth quarter of 2018. Both the 2019 and 2018 periods reflect the change in the fair value of equity securities that are required to be carried at fair value through net earnings under accounting guidance adopted on January 1, 2018,

• higher earnings in the annuity segment,

• higher net investment income in the property and casualty insurance segment,

• lower underwriting profit in the property and casualty insurance segment,

• higher interest charges on borrowed money, and

• higher holding company expenses.

33

Full year 2019 net earnings attributable to AFG’s shareholders were $897 million ($9.85 per share, diluted) compared to $530 million ($5.85 per share, diluted) in 2018, reflecting:

• net realized gains on securities in 2019 compared to net realized losses on securities in 2018,

• higher net investment income in the property and casualty insurance segment,

• lower underwriting profit in the property and casualty insurance segment,

• higher interest charges on borrowed money, and

• higher holding company expenses.

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

• the recoverability of reinsurance,

• the amortization of annuity deferred policy acquisition costs,

• the measurement of the derivatives embedded in indexed annuity liabilities,

• the establishment of asbestos and environmental reserves of former railroad and manufacturing operations, and

• the valuation of investments, including the determination of other-than-temporary impairments.

See “Liquidity and Capital Resources — Uncertainties” for a discussion of insurance reserves, recoverables from reinsurers, indexed annuity embedded derivatives and contingencies related to American Premier’s former operations and “Liquidity and Capital Resources — Investments” for a discussion of impairments on investments. Deferred policy acquisition costs (“DPAC”) and certain liabilities related to annuities are amortized in relation to the present value of expected gross profits on the policies. Assumptions considered in determining expected gross profits involve significant judgment and include management’s estimates of interest rates and investment spreads, surrenders, annuitizations, renewal premiums and mortality. Should actual experience require management to change its assumptions (commonly referred to as “unlocking”), a charge or credit would be recorded to adjust DPAC or annuity liabilities to the levels they would have been if the new assumptions had been used from the inception date of each policy.

LIQUIDITY AND CAPITAL RESOURCES

Ratios   

AFG’s debt to total capital ratio on a consolidated basis is shown below (dollars in millions). Management intends to maintain the ratio of debt to capital at or below 25% and intends to maintain the capital of its significant insurance subsidiaries at or above levels currently indicated by rating agencies as appropriate for the current ratings.

	December 31,
	2019			2018
Principal amount of long-term debt	$	1,493		$	1,318
Total capital	6,883			6,218
Ratio of debt to total capital:
Including subordinated debt	21.7		%	21.2		%
Excluding subordinated debt	14.8		%	16.4		%

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, noncontrolling interests and shareholders’ equity (excluding unrealized gains (losses) related to fixed maturity investments).

34

AFG’s ratio of earnings to fixed charges, including annuity benefits as a fixed charge, was 1.85 for the year ended December 31, 2019. Excluding annuity benefits, this ratio was 14.61. The ratio excluding annuity benefits is presented because interest credited to annuity policyholder accounts is not always considered a borrowing cost for an insurance company.

The NAIC’s model law for risk-based capital (“RBC”) applies to both life and property and casualty companies. RBC formulas determine the amount of capital that an insurance company needs so that it has an acceptable expectation of not becoming financially impaired. At December 31, 2019, the capital ratios of all AFG insurance companies exceeded the RBC requirements.

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):

	Year ended December 31,
	2019			2018			2017
Net cash provided by operating activities	$	2,456		$	2,083		$	1,804
Net cash used in investing activities	(3,065		)	(5,350		)	(3,292		)
Net cash provided by financing activities	1,408			2,444			1,719
Net change in cash and cash equivalents	$	799		$	(823	)	$	231

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. AFG’s annuity operations typically produce positive net operating cash flows as investment income exceeds acquisition costs and operating expenses. Interest credited on annuity policyholder funds is a non-cash increase in AFG’s annuity benefits accumulated liability and annuity premiums, benefits and withdrawals are considered financing activities due to the deposit-type nature of annuities. Cash flows provided by operating activities also include the activity of AFG’s managed investment entities (collateralized loan obligations) 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 $23 million in 2019, $148 million in 2018 and $60 million in 2017, accounting for a $125 million decrease in cash flows from operating activities in 2019 compared to 2018 and an $88 million increase in cash flows from operating activities in 2018 compared to 2017. 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 $2.43 billion, $1.94 billion and $1.74 billion in 2019, 2018 and 2017, respectively.

Net Cash Used in Investing Activities   AFG’s investing activities consist primarily of the investment of funds provided by its property and casualty and annuity businesses. Net cash used in investing activities was $3.07 billion in 2019 compared to $5.35 billion in 2018, a decrease of $2.28 billion. As discussed below (under net cash provided by financing activities), AFG’s annuity segment had net cash flows from annuity policyholders of $1.66 billion in 2019 and $2.76 billion in 2018. In addition, AFG’s cash on hand increased by $799 million during 2019 as AFG held more cash due to fewer investment opportunities in 2019 compared to 2018 when AFG invested a large portion of its cash on hand at the beginning of the year. In addition to the investment of funds provided by the insurance operations, 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 $11 million source of cash in 2019 compared to a $169 million use of cash in 2018, accounting for a $180 million decrease in net cash used in investing activities in 2019 compared to 2018. See Note A — “Accounting Policies — Managed Investment Entities” and Note H — “Managed Investment Entities” to the financial statements.

35

Net cash used in investing activities was $5.35 billion in 2018 compared to $3.29 billion in 2017, an increase of $2.06 billion. As discussed below (under net cash provided by financing activities), AFG’s annuity group had net cash flows from annuity policyholders of $2.76 billion in 2018 and $1.99 billion in 2017. In addition, AFG’s cash on hand decreased by $823 million during 2018 as AFG invested a large portion of its cash on hand at December 31, 2017. Net investment activity in the managed investment entities was a $169 million use of cash in 2018 compared to a $205 million use of cash in 2017, accounting for a $36 million decrease in net cash used in investing activities in 2018 compared to 2017.

Net Cash Provided by Financing Activities   AFG’s financing activities consist primarily of transactions with annuity policyholders, issuances and retirements of long-term debt, issuances and repurchases of common stock, and dividend payments. Net cash provided by financing activities was $1.41 billion in 2019 compared to $2.44 billion in 2018, a decrease of $1.03 billion. Annuity receipts exceeded annuity surrenders, benefits, withdrawals and transfers by $1.66 billion in 2019 compared to $2.76 billion in 2018, resulting in a $1.10 billion decrease in net cash provided by financing activities in 2019 compared to 2018. In 2019, AFG issued $125 million of 5.875% Subordinated Debentures due in 2059 and $200 million of 5.125% Subordinated Debentures due in 2059, the net proceeds of which contributed $315 million to net cash provided by financing activities in 2019. The December redemption of AFG’s 6-1/4% Subordinated Debentures was a $150 million use of cash in 2019. During 2018, AFG had no additional long-term borrowings or repayments. In addition to its regular quarterly cash dividends, AFG paid special cash dividends of $3.30 per share and $3.00 per share in 2019 and 2018, respectively, which resulted in total cash dividends of $444 million in 2019 compared to $394 million in 2018. 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 $11 million in 2019 compared to issuances of managed investment entity liabilities exceeding retirements by $48 million in 2018, accounting for a $59 million decrease in net cash provided by financing activities in 2019 compared to 2018. See Note A — “Accounting Policies — Managed Investment Entities” and Note H — “Managed Investment Entities” to the financial statements.

Net cash provided by financing activities was $2.44 billion in 2018 compared to $1.72 billion in 2017, an increase of $725 million. Annuity receipts exceeded annuity surrenders, benefits, withdrawals and transfers by $2.76 billion in 2018 compared to $1.99 billion in 2017, resulting in a $773 million increase in net cash provided by financing activities in 2018 compared to 2017. During 2018, AFG had no additional long-term borrowings or repayments compared to $712 million of additional long-term borrowings and $745 million of debt repayments in 2017. In addition to its regular quarterly cash dividends, AFG paid special cash dividends of $3.00 per share and $3.50 per share in 2018 and 2017, respectively, which resulted in total cash dividends of $394 million in 2018 compared to $417 million in 2017. Issuances of managed investment entity liabilities exceeded retirements by $48 million in 2018 compared to $146 million in 2017, accounting for a $98 million decrease in net cash provided by financing activities in 2018 compared to 2017.

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 marketable securities or to generate cash through borrowings, sales of other assets, or similar transactions.

AFG can borrow up to $500 million under its revolving credit facility which expires in June 2021. Amounts borrowed under this agreement bear interest at rates ranging from 1.00% to 1.875% (currently 1.375%) over LIBOR based on AFG’s credit rating. There were no borrowings under this agreement, or under any other parent company short-term borrowing arrangements, during 2019.

In 2019, AFG paid special cash dividends of $3.30 per share of AFG Common Stock ($1.50 per share in May and $1.80 per share in November) totaling approximately $297 million.

In March 2019, AFG issued $125 million of 5.875% Subordinated Debentures due in March 2059. The net proceeds of the

offering were used for general corporate purposes.

On December 2, 2019, AFG issued $200 million of 5.125% Subordinated Debentures due in December 2059. A portion of the net proceeds of the offering were used to redeem AFG’s $150 million outstanding principal amount of 6-1/4% Subordinated Debentures due in September 2054, at par value on December 23, 2019, with the remainder used for general corporate purposes.

In 2018, AFG paid special cash dividends of $3.00 per share of AFG Common Stock ($1.50 per share in May and November) totaling approximately $267 million and repurchased 65,589 shares of its Common Stock for $6 million.

36

In June 2017, AFG issued $350 million of 4.50% Senior Notes due in June 2047. Net proceeds from the offering were used to redeem AFG’s $230 million outstanding principal amount of 6-3/8% Senior Notes due in June 2042, at par value in June 2017 and AFG’s $125 million outstanding principal amount of 5-3/4% Senior Notes due in August 2042 at par value in August 2017.

In November 2017, AFG issued an additional $240 million of 4.50% Senior Notes due in 2047 and $125 million of 3.50% Senior Notes due in 2026. The net proceeds of the offering were used to redeem AFG’s $350 million outstanding principal amount of 9-7/8% Senior Notes due in June 2019 for $388 million (including a make-whole premium of $38 million) in December 2017.

In 2017, AFG paid special cash dividends of $3.50 per share of AFG Common Stock ($1.50 per share in May and $2.00 per share in November) totaling approximately $308 million.

All debentures and notes issued by AFG are rated investment grade by two nationally recognized rating agencies. Under a currently effective shelf registration statement, AFG can offer additional equity or debt securities. The shelf registration provides AFG with flexibility to access the capital markets from time to time as market and other conditions permit.

Under a tax allocation agreement with AFG, its 80%-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   Great American Life Insurance Company (“GALIC”), a wholly-owned annuity subsidiary, is a member of the Federal Home Loan Bank of Cincinnati (“FHLB”). The FHLB makes advances and provides other banking services to member institutions, which provides the annuity operations with an additional source of liquidity. At December 31, 2019, GALIC had $1.1 billion in outstanding advances from the FHLB (included in annuity benefits accumulated), bearing interest at rates ranging from 0.13% to 0.21% over LIBOR (average rate of 1.95% at December 31, 2019). While these advances must be repaid between 2020 and 2021 ($310 million in 2020 and $786 million in 2021), GALIC has the option to prepay all or a portion of the advances. GALIC has invested the proceeds from the advances in fixed maturity securities with similar expected lives as the advances for the purpose of earning a spread over the interest payments due to the FHLB. At December 31, 2019, GALIC estimated that it had additional borrowing capacity of approximately $800 million from the FHLB.

In the fourth quarter of 2018, GALIC, AFG’s primary annuity subsidiary, entered into a reinsurance treaty with Hannover Life Reassurance Company of America that transfers the risk of certain surrender activity in GALIC’s fixed-indexed annuity business. This treaty meets the statutory risk transfer rules and resulted in a $510 million increase in statutory surplus (through an after-tax reserve credit). The treaty reduces statutory capital and surplus volatility related to GALIC’s fixed-indexed annuity policies from stock market fluctuations, which could impact GALIC’s risk-based capital and the amount of dividends available in future periods. Under GAAP, this transaction does not meet the GAAP insurance risk transfer criteria and did not have a material impact on AFG’s financial statements.

The liquidity requirements of AFG’s insurance subsidiaries relate primarily to the liabilities associated with their products as well as operating costs and expenses, payments of dividends and taxes to AFG and contributions of capital to their subsidiaries. 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 additional marketable securities. In addition, the insurance subsidiaries generally hold a significant amount of highly liquid, short-term investments.

The excess cash flow of AFG’s property and casualty group allows it to extend the duration of its investment portfolio somewhat beyond that of its claim reserves.

37

In the annuity business, where profitability is largely dependent on earning a spread between invested assets and annuity liabilities, the duration of investments is generally maintained close to that of liabilities. In a rising interest rate environment, significant protection from withdrawals exists in the form of temporary and permanent surrender charges on AFG’s annuity products. With declining rates, AFG receives some protection (from spread compression) due to the ability to lower crediting rates, subject to contractually guaranteed minimum interest rates (“GMIRs”). At December 31, 2019, AFG could reduce the average crediting rate on approximately $30 billion of traditional fixed, fixed-indexed and variable-indexed annuities without guaranteed withdrawal benefits by approximately 119 basis points (on a weighted average basis). Annuity policies are subject to GMIRs at policy issuance. The table below shows the breakdown of annuity reserves by GMIR. The current interest crediting rates on substantially all of AFG’s annuities with a GMIR of 3% or higher are at their minimum.

	% of Reserves
	at December 31,
GMIR	2019	2018	2017
1 — 1.99%	81%	79%	76%
2 — 2.99%	3%	4%	5%
3 — 3.99%	7%	8%	10%
4.00% and above	9%	9%	9%
Annuity benefits accumulated (in millions)	$40,406	$36,616	$33,316

For statutory accounting purposes, equity securities of non-affiliates and equity call and put options used in the fixed-indexed and variable-indexed annuity business are generally carried at fair value. At December 31, 2019, AFG’s insurance companies owned publicly traded equity securities with a fair value of $1.87 billion and equity index call and put options with a net fair value of $923 million. Decreases in market prices could adversely affect the insurance group’s capital, potentially impacting the amount of dividends available or necessitating a capital contribution. Conversely, increases in market prices could have a favorable impact on the group’s dividend-paying capability.

AFG believes its insurance subsidiaries maintain sufficient liquidity to pay claims and benefits and operating 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. 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.

Condensed Parent Only Cash Flows   

AFG’s parent holding company only condensed cash flows from operating, investing and financing activities are shown below (in millions):

	Year ended December 31,
	2019			2018			2017
Net cash provided by operating activities	$	306		$	215		$	578
Net cash provided by (used in) investing activities	(56		)	10			(63		)
Net cash used in financing activities	(242		)	(366		)	(413		)
Net change in cash and cash equivalents	$	8		$	(141	)	$	102

Parent Net Cash Provided by Operating Activities   Parent holding company cash flows from operating activities consist primarily of dividends and tax payments received from AFG’s insurance subsidiaries, reduced by tax payments to the IRS and holding company interest and other expenses. Parent holding company net cash provided by operating activities was $306 million in 2019 compared to $215 million in 2018 and $578 million in 2017. The $91 million increase in net cash provided by operating activities in 2019 as compared to 2018 was due primarily to higher dividends received from subsidiaries in 2019 as compared to 2018. The $363 million decrease in net cash provided by operating activities in 2018 as compared to 2017 was due to lower dividends received from subsidiaries.

Parent Net Cash Provided by (Used in) Investing Activities   Parent holding company investing activities consist of capital contributions to and returns of capital from subsidiaries and, to a much lesser extent, parent company investment activity. Parent holding company net cash used in investing activities was $56 million in 2019 compared to net cash provided by investing activities of $10 million in 2018 and net cash used in investing activities of $63 million in 2017. The fluctuations in net cash provided by (used in) investing activities are due primarily to higher capital contributions to subsidiaries in 2019 and 2017 as compared to 2018.

38

Parent Net Cash Used in Financing Activities   Parent company financing activities consist primarily of the issuance and retirement of long-term debt, dividends to shareholders, and, to a lesser extent, proceeds from employee stock option exercises and repurchases of AFG Common Stock. Significant long-term debt and common stock transactions are discussed above under “Parent Holding Company Liquidity.” Parent holding company net cash used in financing activities was $242 million in 2019 compared to $366 million in 2018 and $413 million in 2017. The $124 million decrease in net cash used in financing activities in 2019 as compared to 2018 reflects the net issuances of long-term debt in 2019, partially offset by increased dividends (due primarily to special dividends of $3.30 per share in 2019 compared to $3.00 per share in 2018). The $47 million decrease in net cash used in financing activities in 2018 as compared to 2017 reflects lower net redemptions of long-term debt in 2018 and decreased dividends (due primarily to special dividends of $3.00 per share in 2018 compared to $3.50 per share in 2017).

Contractual Obligations   

The following table shows an estimate (based on historical patterns and expected trends) of payments to be made for insurance reserve liabilities, as well as scheduled payments for major contractual obligations (in millions).

	Total		Within One Year		2-3 Years		4-5 Years		More than 5 Years
Annuities (a)	$	45,451	$	3,546	$	8,819	$	11,035	$	22,051
Life, accident and health liabilities (a)	1,283		101		207		163		812
Property and casualty unpaid losses and loss adjustment expenses (b)	10,232		2,834		2,753		1,156		3,489
Long-term debt, including interest	3,349		68		136		136		3,009
Operating leases (c)	202		47		73		47		35
Total	$	60,517	$	6,596	$	11,988	$	12,537	$	29,396

(a) Amounts presented in the table represent estimated cash payments under such contracts, based on significant assumptions related to mortality, morbidity, lapse, renewal, retirement and annuitization. These assumptions also include interest and index crediting consistent with assumptions used to amortize DPAC and assess loss recognition. All estimated cash payments are undiscounted for the time value of money. As a result, total outflows for all years exceed the corresponding liabilities of $40.41 billion for annuity benefits accumulated and $612 million for life, accident and health reserves included in AFG’s Balance Sheet as of December 31, 2019. Based on the same assumptions, AFG projects reinsurance recoveries related to life, accident and health reserves totaling $597 million as follows: Within 1 year — $60 million; 2-3 years — $100 million; 4-5 years — $76 million; and thereafter — $361 million. Actual payments and their timing could differ significantly from these estimates.

(b) Dollar amounts and time periods are estimates based on historical net payment patterns applied to the gross reserves and do not represent actual contractual obligations. Based on the same assumptions, AFG projects reinsurance recoveries related to these reserves totaling $3.02 billion as follows: Within 1 year — $838 million; 2-3 years — $813 million; 4-5 years — $342 million; and thereafter — $1.03 billion. Actual payments and their timing could differ significantly from these estimates.

(c) Amounts presented in the table represent lease component payments, including short-term lease payments, and exclude non-lease component payments of building leases (primarily common area maintenance and property tax payments). Estimated non-lease component payments totaling $92 million are as follows: Within 1 year — $17 million; 2-3 years — $30 million; 4-5 years — $24 million; and thereafter — $21 million.

AFG has no material contractual purchase obligations or other long-term liabilities at December 31, 2019.

Off-Balance Sheet Arrangements  

See Note Q — “Additional Information — Financial Instruments — Unfunded Commitments” to the financial statements.

Investments   

AFG attempts to optimize investment income while building the value of its portfolio, placing emphasis upon total long-term performance.

AFG’s investment portfolio at December 31, 2019, contained $46.51 billion in fixed maturity securities classified as available for sale and carried at fair value with unrealized gains and losses included in a separate component of shareholders’ equity on an after-tax basis and $113 million in fixed maturities classified as trading with holding gains and losses included in net investment income. In addition, AFG’s investment portfolio includes $1.64 billion in equity securities carried at fair value with holding gains and losses included in realized gains (losses) on securities and $294 million in equity securities carried at fair value with holding gains and losses included in net investment income.

39

As detailed in Note E — “Investments — Net Unrealized Gain on Marketable Securities” to the financial statements, unrealized gains and losses on AFG’s fixed maturity securities are included in shareholders’ equity after adjustments for related changes in DPAC and certain liabilities related to annuity, long-term care and life businesses and deferred income taxes. DPAC and certain other balance sheet amounts applicable to annuity, long-term care and life businesses are adjusted for the impact of unrealized gains or losses on investments as if these gains or losses had been realized, with corresponding increases or decreases (net of tax) included in accumulated other comprehensive income in AFG’s Balance Sheet.

Fixed income investment funds are generally invested in securities with intermediate-term maturities with an objective of optimizing total return while allowing flexibility to react to changes in market conditions. At December 31, 2019, the average life of AFG’s fixed maturities was about 5-1/2 years.

Fair values for AFG’s portfolio are determined by AFG’s internal investment professionals using data from nationally recognized pricing services as well as non-binding broker quotes. Fair values of equity securities are generally based on published closing prices. For AFG’s fixed maturity portfolio, approximately 90% was priced using pricing services at December 31, 2019 and the balance was priced primarily by 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 and accumulated other comprehensive income that an immediate increase of 100 basis points in the interest rate yield curve would have at December 31, 2019 (dollars in millions). Effects of increases or decreases from the 100 basis points illustrated would be approximately proportional.

Fair value of fixed maturity portfolio	$	46,618
Percentage impact on fair value of 100 bps increase in interest rates	(4.0		%)
Pretax impact on fair value of fixed maturity portfolio	$	(1,865	)
Offsetting adjustments to deferred policy acquisition costs and other balance sheet amounts	850
Estimated pretax impact on accumulated other comprehensive income	(1,015		)
Deferred income tax	213
Estimated after-tax impact on accumulated other comprehensive income	$	(802	)

Approximately 91% of the fixed maturities held by AFG at December 31, 2019, were rated “investment grade” (credit rating of AAA to BBB) by nationally recognized rating agencies. 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.

MBS are subject to significant prepayment risk because, in periods of declining interest rates, mortgages may be repaid more rapidly than scheduled as borrowers refinance higher rate mortgages to take advantage of lower rates.

40

Summarized information for AFG’s MBS (including those classified as trading) at December 31, 2019, is shown in the table below (dollars in millions). Agency-backed securities are those issued by a U.S. government-backed agency; Alt-A mortgages are those with risk profiles between prime and subprime. The average life of the residential and commercial MBS is approximately 4-1/2 years and 3 years, respectively.

	Amortized Cost		Fair Value		Fair Value as % of Cost		Unrealized Gain (Loss)		% Rated Investment Grade
Collateral type
Residential:
Agency-backed	$	549	$	552	101	%	$	3	100	%
Non-agency prime	1,157		1,264		109	%	107		53	%
Alt-A	897		1,015		113	%	118		37	%
Subprime	298		330		111	%	32		25	%
Commercial	896		927		103	%	31		96	%
	$	3,797	$	4,088	108	%	$	291	63	%

The National Association of Insurance Commissioners (“NAIC”) assigns creditworthiness designations on a scale of 1 to 6 with 1 being the highest quality and 6 being the lowest quality. The NAIC retains third-party investment management firms to assist in the determination of appropriate NAIC designations for MBS based not only on the probability of loss (which is the primary basis of ratings by the major ratings firms), but also on the severity of loss and statutory carrying value. At December 31, 2019, 97% (based on statutory carrying value of $3.74 billion) of AFG’s MBS had an NAIC designation of 1.

Municipal bonds represented approximately 15% of AFG’s fixed maturity portfolio at December 31, 2019. AFG’s municipal bond portfolio is high quality, with 99% of the securities rated investment grade at that date. The portfolio is well diversified across the states of issuance and individual issuers. At December 31, 2019, approximately 79% of the municipal bond portfolio was held in revenue bonds, with the remaining 21% held in general obligation bonds.

Summarized information for the unrealized gains and losses recorded in AFG’s Balance Sheet at December 31, 2019, is shown in the following table (dollars in millions). Approximately $1.09 billion of available for sale fixed maturity securities had no unrealized gains or losses at December 31, 2019.

When a decline in the value of a specific investment is considered to be other-than-temporary, a provision for impairment is charged to earnings (accounted for as a realized loss) and the cost basis of that investment is reduced by the amount of the charge. The determination of whether unrealized losses are other-than-temporary requires judgment based on subjective as well as objective factors. Factors considered and resources used by management include:

a) whether the unrealized loss is credit-driven or a result of changes in market interest rates,

b) the extent to which fair value is less than cost basis,

c) cash flow projections received from independent sources,

d) historical operating, balance sheet and cash flow data contained in issuer SEC filings and news releases,

42

e) near-term prospects for improvement in the issuer and/or its industry,

f) third-party research and communications with industry specialists,

g) financial models and forecasts,

h) the continuity of interest payments, maintenance of investment grade ratings and hybrid nature of certain investments,

i) discussions with issuer management, and

j) ability and intent to hold the investment for a period of time sufficient to allow for anticipated recovery in fair value.

Based on its analysis of the factors listed above, management believes AFG will recover its cost basis 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 December 31, 2019. 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, charges for other-than-temporary impairment 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, including charges for other-than-temporary impairment, see “Results of Operations — Consolidated Realized Gains (Losses) on Securities.”

Uncertainties   

As more fully explained in the following paragraphs, 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.

Property and Casualty Insurance Reserves   Estimating the liability for unpaid losses and loss adjustment expenses (“LAE”) is inherently judgmental and is influenced by factors that are subject to significant variation. Determining the liability is a complex process incorporating input from many areas of the Company including actuarial, underwriting, pricing, claims and operations management.

The estimates of liabilities for unpaid claims and for expenses of investigation and adjustment of unpaid claims are based upon: (i) the accumulation of case estimates for losses reported prior to the close of the accounting periods on direct business written (“case reserves”); (ii) estimates received from ceding reinsurers and insurance pools and associations; (iii) estimates of claims incurred but not reported or “IBNR” (including possible development on known claims); (iv) estimates (based on experience) of expense for investigating and adjusting claims; and (v) the current state of law and coverage litigation.

The process used to determine the total reserve for liabilities involves estimating the ultimate incurred losses and LAE, adjusted for amounts already paid on the claims. The IBNR reserve is derived by first estimating the ultimate unpaid reserve liability and subtracting case reserves for loss and LAE. See Note P — “Insurance — Property and Casualty Insurance Reserves” to the financial statements for a discussion of the factors considered and actuarial methods used in determining management’s best estimate of the ultimate liability for unpaid losses and LAE.

43

The following table shows (in millions) the breakdown of AFG’s property and casualty insurance reserves between case reserves, IBNR reserves and LAE reserves (estimated amounts required to adjust, record and settle claims, other than the claim payments themselves) at December 31, 2019 and gross written premiums for the year ended December 31, 2019.

While current factors and reasonably likely changes in variable factors are considered in estimating the liability for unpaid losses and LAE, there is no method or system that can eliminate the risk of actual ultimate results differing from such estimates.

Following is a discussion of certain critical variables affecting the estimation of loss reserves of the more significant long-tail lines of business (asbestos and environmental liabilities are separately discussed below). Many other variables may also impact ultimate claim costs.

An important assumption underlying reserve estimates is that the cost trends implicitly built into development patterns will continue into the future. However, future results could vary due to an unexpected change in the underlying cost trends. This unexpected change could arise from a variety of sources including a general increase in economic inflation, inflation from social programs, new medical technologies, or other factors such as those listed below in connection with AFG’s largest lines of business. It is not possible to isolate and measure the potential impact of just one of these variables, and future cost trends could be partially impacted by several such variables. However, it is reasonable to address the sensitivity of the reserves to potential impact from changes in these variables by measuring the effect of a possible overall 1% change in future cost trends that may be caused by one or more variables. Utilizing the effect of a 1% change in overall cost trends enables changes greater than 1% to be estimated by extrapolation. Each additional 1% change in the cost trend would increase the effect on net earnings by an amount slightly (about 5%) greater than the effect of the previous 1%. For example, if a 1% change in cost trends in a line of business would change net earnings by $20 million, a 2% change would change net earnings by approximately $41 million.

The estimated cumulative impact that a 1% change in cost trends in AFG’s more significant lines of property and casualty business (exceeding 5% of total reserves) would have on net earnings is shown below (in millions).

Line of business	Effect of 1% Change in Cost Trends
Other liability — occurrence	$	45
Workers’ compensation	72
Other liability — claims made	15
Commercial auto/truck liability/medical	10

44

The judgments and uncertainties surrounding management’s reserve estimation process and the potential for reasonably possible variability in management’s most recent reserve estimates may also be viewed by looking at how recent historical estimates of reserves have developed. The following table shows (dollars in millions) what the impact on AFG’s net earnings would be on the more significant lines of business if the December 31, 2019, reserves (net of reinsurance) developed at the same rate as the average development of the most recent five years.

	5-yr. Average Development (a)(b)		Net Reserves (b) December 31, 2019		Effect on Net Earnings (b)
Other liability — occurrence	4.5	%	$	1,428	$	(64	)
Workers’ compensation	(3.7	%)	2,283		84
Other liability — claims made	(2.1	%)	605		13
Commercial auto/truck liability/medical	0.3	%	508		(2		)

(a) Adverse (favorable), net of tax effect.

(b) Excludes asbestos and environmental liabilities.

The following discussion describes key assumptions and important variables that affect the estimate of the reserve for loss and LAE of the more significant lines of business and explains what caused them to change from assumptions used in the preceding period.

Other Liability — Occurrence

This long-tail line of business consists of coverages protecting the insured against legal liability resulting from negligence, carelessness, or a failure to act causing property damage or personal injury to others. Some of the important variables affecting estimation of loss reserves for other liability — occurrence include:

• Litigious climate

• Unpredictability of judicial decisions regarding coverage issues

• Magnitude of jury awards

• Outside counsel costs

• Timing of claims reporting

AFG recorded adverse prior year reserve development of $143 million in 2019 related to its other liability — occurrence coverage due primarily to continued claim severity increases in excess and umbrella liability coverages. AFG recorded adverse prior year reserve development of $48 million in 2018 due to claim severity increases in excess and umbrella liability coverages as well as late emergence of excess workers’ compensation and Texas non-subscribers workers’ injury claims. AFG recorded adverse prior year reserve development of $37 million in 2017 due to increased severity of New York contractor claims, as well as increased claim severity across other excess and umbrella liability coverages and general liability coverages.

While management applies the actuarial methods mentioned above, more judgment is involved in arriving at the final reserve to be held. For recent accident years, more weight is given to the Bornhuetter-Ferguson method.

Workers’ Compensation

This long-tail line of business provides coverage to employees who may be injured in the course of employment. Some of the important variables affecting estimation of loss reserves for workers’ compensation include:

• Legislative actions and regulatory and legal interpretations

• Future medical cost inflation

• Economic conditions

• Frequency of reopening claims previously closed

• Advances in medical equipment and processes

• Pace and intensity of employee rehabilitation

• Changes in the use of pharmaceutical drugs

• Changes in longevity trends for permanently injured workers

Approximately 27% and 23% of AFG’s workers’ compensation reserves at December 31, 2019 relate to policies written in Florida and California, respectively. The Castellanos v. Next Door Company decision in Florida and the implementation of Senate Bill 863 in California are two examples of recent changes that impacted the workers’ compensation operating environment and added difficulty and uncertainty to the estimation of related liabilities.

45

AFG recorded favorable prior year reserve development of $180 million in 2019 related to its workers’ compensation coverage due to lower than anticipated frequency of lost-time claims and medical severity. AFG recorded favorable prior year reserve development of $127 million in 2018 due to lower than anticipated claim severity in the southeastern United States and improving claim closure rates in California. AFG recorded favorable prior year reserve development of $79 million in 2017 due to lower than anticipated claim severity and improving claim closure rates, particularly in the southeastern United States and California.

Other Liability — Claims Made

This long-tail line of business consists mostly of directors’ and officers’ liability (“D&O”). Some of the important variables affecting estimation of loss reserves for other liability — claims made include:

• Litigious climate

• Economic conditions

• Variability of stock prices

• Magnitude of jury awards

The general state of the economy and the variability of the stock price of the insured can affect the frequency and severity of shareholder class action suits and other situations that trigger coverage under D&O policies. For example, from 2008 to 2010, economic conditions led to higher frequency of claims, particularly in the D&O policies for small account and not-for-profit organizations. Since then, claim frequency has decreased from its peak in 2010 and has stabilized to near pre-2008 levels.

AFG recorded favorable prior year reserve development of $4 million in 2019, $9 million in 2018 and $5 million in 2017 on its D&O business as claim severity was less than expected across several prior accident years.

Commercial Auto/Truck Liability/Medical

This line of business is a mix of coverage protecting the insured against legal liability for property damage or personal injury to others arising from the operation of commercial motor vehicles. The property damage liability exposure is usually short-tail with relatively quick reporting and settlement of claims. The bodily injury and medical payments exposures are longer-tailed; although the claim reporting is relatively quick, the final settlement can take longer to achieve. Some of the important variables affecting estimation of loss reserves for commercial auto/truck liability/medical are similar to other liability — occurrence and include:

• Magnitude of jury awards

• Unpredictability of judicial decisions regarding coverage issues

• Litigious climate and trends

• Change in frequency of severe accidents

• Health care costs and utilization of medical services by injured parties

AFG recorded favorable prior year reserve development of $15 million in 2019 for this line of business due primarily to lower than expected claim frequency and severity. AFG recorded favorable prior year reserve development of $26 million in 2018 due primarily to lower than expected claim severity. AFG recorded adverse prior year reserve development of $2 million in 2017 for this line of business.

Reserves of Foreign Operations

Approximately $512 million of the $804 million in gross reserves of foreign operations relate to the operations of Neon Underwriting Limited, AFG’s wholly-owned United Kingdom-based Lloyd’s insurer. In December 2019, AFG initiated actions to exit the Lloyd’s of London insurance market, which included placing its Lloyd’s Managing Agency, Neon Underwriting Ltd., into run-off. Neon’s reserves will decline as the business is run-off. Historically, Neon wrote cargo, cyber, financial lines, marine and energy liability, marine hull and war, general casualty, personal accident and health, political and trade risk, professional indemnity, property insurance and reinsurance, and terrorism and political violence insurance. Significant variables in estimating Neon’s loss reserves include:

• Litigious environment

• Magnitude of court awards

• Trends in claim costs, including medical cost inflation

• Global economic conditions

• Reporting lag from ceding property insurers

46

Neon recorded adverse prior year reserve development of $13 million in 2019, due primarily to lower than expected recoveries and higher than expected claim severity of assumed property catastrophe losses and reserve strengthening in its general casualty, ocean marine and non-catastrophe property lines of business.

Neon recorded favorable prior year reserve development of $26 million in 2018, due primarily to lower than expected emergence in assumed 2017 property catastrophe losses.

In the fourth quarter of 2017, Neon entered into a reinsurance to close agreement for 2015 and prior years of account, which transfers the responsibility for all of the liabilities that attach to the transferred year of account (gross reserves of $385 million at December 31, 2017) as well as any income due to the closing year of account in return for a premium. The reinsurance to close agreement eliminates any remaining reserve volatility from years of account 2015 and prior, including all medical malpractice exposure. As a result of the reinsurance to close transaction, Neon recorded favorable reserve development of approximately $42 million, including $24 million related to its ongoing lines of business and $18 million that relates to exited lines of business. In addition to the prior year reserve development related to the reinsurance to close transaction, Neon recorded favorable prior year reserve development of $29 million in 2017 related to the retained loss reserves across all of Neon’s ongoing lines of business, particularly property lines.

Recoverables from Reinsurers and Availability of Reinsurance   AFG is subject to credit risk with respect to its reinsurers, as reinsurance contracts do not relieve AFG of its liability to policyholders. To mitigate this risk, substantially all reinsurance is ceded to companies rated “A” or better by S&P or is secured by “funds withheld” or other collateral.

The availability and cost of reinsurance are subject to prevailing market conditions, which are beyond AFG’s control and which may affect AFG’s level of business and profitability. Although the cost of certain reinsurance programs may increase, management believes that AFG will be able to maintain adequate reinsurance coverage at acceptable rates without a material adverse effect on AFG’s results of operations. AFG’s gross and net combined ratios are shown in the table below.

See Item 1 — Business — “Property and Casualty Insurance Segment — Reinsurance” for more information on AFG’s reinsurance programs. For additional information on the effect of reinsurance on AFG’s historical results of operations see Note P — “Insurance — Reinsurance” to the financial statements.

The following table illustrates the effect that purchasing property and casualty reinsurance has had on AFG’s combined ratio over the last three years. 

	2019		2018		2017
Before reinsurance (gross)	95.6	%	94.1	%	98.9	%
Effect of reinsurance	0.2	%	(0.3	%)	(4.2	%)
Actual (net of reinsurance)	95.8	%	93.8	%	94.7	%

Outside of its property and casualty operations, AFG also has reinsurance recoverables totaling $282 million, including $228 million related to the run-off life business. These recoverables include $195 million directly or indirectly from Hannover Life Reassurance Company of America (rated AA- by S&P).

Asbestos and Environmental-related (“A&E”) Insurance Reserves   Asbestos and environmental reserves of the property and casualty group consisted of the following (in millions): 

	December 31,
	2019		2018
Asbestos	$	221	$	234
Environmental	162		161
A&E reserves, net of reinsurance recoverable	383		395
Reinsurance recoverable, net of allowance	146		129
Gross A&E reserves	$	529	$	524

Asbestos reserves include claims asserting alleged injuries and damages from exposure to asbestos. Environmental reserves include claims relating to polluted sites.

Asbestos claims against manufacturers, distributors or installers of asbestos products were presented under the products liability section of their policies, which typically had aggregate limits that capped an insurer’s liability. In addition, asbestos claims are being presented as “non-products” claims, such as those by installers of asbestos products and by property

47

owners or operators who allegedly had asbestos on their property, under the premises or operations section of their policies. Unlike products exposures, these non-products exposures typically had no aggregate limits, creating greater exposure for insurers. Further, in an effort to seek additional insurance coverage, some insureds with installation activities who have substantially eroded their products coverage are presenting new asbestos claims as non-products operations claims or attempting to reclassify previously settled products claims as non-products claims to restore a portion of previously exhausted products aggregate limits.

Approximately 41% of AFG’s net asbestos reserves relate to policies written directly by AFG subsidiaries. Claims from these policies generally are product-oriented claims with only a limited amount of non-products exposures and are dominated by small to mid-sized commercial entities that are mostly regional policyholders with few national target defendants. The remainder is assumed reinsurance business that includes exposures from 1954 to 1983. The asbestos and environmental assumed claims are ceded by various insurance companies under reinsurance treaties. A majority of the individual assumed claims have exposures of less than $100,000 to AFG. Asbestos losses assumed include some of the industry known manufacturers, distributors and installers. Pollution losses include industry known insured names and sites.

Establishing reserves for A&E claims relating to policies and participations in reinsurance treaties and former operations is subject to uncertainties that are significantly greater than those presented by other types of claims. For this group of claims, traditional actuarial techniques that rely on historical loss development trends cannot be used and a range of reasonably possible losses cannot be estimated. Case reserves and expense reserves are established by the claims department as specific policies are identified. In addition to the case reserves established for known claims, management establishes additional reserves for claims not yet known or reported and for possible development on known claims. These additional reserves are management’s best estimate based on periodic comprehensive studies and internal reviews adjusted for payments and identifiable changes, supplemented by management’s review of industry information about such claims, with due consideration to individual claim situations.

Management believes that estimating the ultimate liability for asbestos claims presents a unique and difficult challenge to the insurance industry 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. Environmental claims likewise present challenges in prediction, due to uncertainty regarding the interpretation of insurance policies, complexities regarding multi-party involvements at sites, evolving cleanup standards and protracted time periods required to assess the level of cleanup required at contaminated sites.

The following factors could impact AFG’s A&E reserves and payments:

• There is interest at the state level to attempt to legislatively address asbestos liabilities and the manner in which asbestos claims are resolved. These developments are fluid and could result in piecemeal state-by-state solutions.

• The manner by which bankruptcy courts are addressing asbestos liabilities is in flux.

• AFG’s insureds may make claims alleging significant non-products exposures.

While management believes that AFG’s reserves for A&E claims are a reasonable estimate of ultimate liability for such claims, actual results may vary materially from the amounts currently recorded due to the difficulty in predicting the number of future claims, the impact of bankruptcy filings and unresolved issues such as whether coverage exists, whether policies are subject to aggregate limits on coverage, how claims are to be allocated among triggered policies and implicated years and whether claimants who exhibit no signs of illness will be successful in pursuing their claims. A 1% variation in loss cost trends, caused by any of the factors previously described, would change net earnings by approximately $32 million.

48

AFG tracks its A&E claims by policyholder. The following table shows, by type of claim, the number of policyholders that did not receive any payments in the calendar year separate from policyholders that did receive a payment. Policyholder counts represent policies written by AFG subsidiaries and do not include assumed reinsurance. 

	2019	2018	2017
Number of policyholders with no indemnity payments:
Asbestos	98	94	81
Environmental	113	112	101
	211	206	182
Number of policyholders with indemnity payments:
Asbestos	46	49	74
Environmental	17	32	31
	63	81	105
Total	274	287	287

Amounts paid (net of reinsurance recoveries) for asbestos and environmental claims, including LAE, were as follows (in millions):

	2019		2018		2017
Asbestos	$	17	$	9	$	11
Environmental	13		17		12
Total	$	30	$	26	$	23

The survival ratio is a measure often used by industry analysts to compare A&E reserves’ strength among companies. This ratio is typically calculated by dividing reserves for A&E exposures by the three-year average of paid losses, and therefore measures the number of years that it would take to pay off current reserves based on recent average payments. Because this ratio can be significantly impacted by a number of factors such as loss payout variability, caution should be exercised in attempting to determine reserve adequacy based simply on the survival ratio. At December 31, 2019, the property and casualty insurance segment’s three-year survival ratios compare favorably with industry survival ratios published by A.M. Best (as of December 31, 2018, and adjusted for several large portfolio transfers) as detailed in the following table:

	Property and Casualty Insurance Reserves
	Three-Year Survival Ratio (Times Paid Losses)
	Asbestos	Environmental	Total A&E
AFG (12/31/2019)	17.9	11.8	14.6
Industry (12/31/2018)	7.0	8.3	7.3

During the third quarter of 2019, AFG completed and in-depth internal review of its A&E exposures relating to the run-off operations of its property and casualty insurance segment and its exposures related to former railroad and manufacturing operations and sites. In addition to its ongoing internal monitoring of A&E exposures, AFG has periodically conducted comprehensive external studies of its A&E reserves with the aid of specialty actuarial, engineering and consulting firms and outside counsel, with an in-depth internal review during the intervening years. AFG has historically conducted an external study every two years. The most recent external study was in the third quarter of 2017 and AFG is currently evaluating the frequency of future external studies.

As a result of the 2019 internal review, AFG’s property and casualty insurance segment recorded an $18 million pretax special charge to increase its asbestos reserves by $3 million (net of reinsurance) and its environmental reserves by $15 million (net of reinsurance). Over the past few years, the focus of AFG’s asbestos claims litigation has shifted to smaller companies and companies with ancillary exposures. AFG’s insureds with these exposures have been the driver of the property and casualty segment’s asbestos reserve increases in recent years. AFG is seeing modestly increasing estimates for indemnity and defense compared to prior studies on certain specific open claims.

The increase in property and casualty environmental reserves was primarily associated with updated estimates of site

investigation and remedial costs with respect to existing sites and newly identified sites. AFG has updated its view of legal

defense costs on open environmental claims as well as a number of claims and sites where the estimated investigation and remediation costs have increased. As in past years, there were no new or emerging broad industry trends that were identified in this review.

An in-depth internal review of AFG’s A&E reserves was also completed in the third quarter of 2018. As a result of the 2018 internal review, AFG’s property and casualty insurance segment recorded an $18 million pretax special charge to increase

49

its asbestos reserves by $6 million (net of reinsurance) and its environmental reserves by $12 million (net of reinsurance). The increase in property and casualty asbestos reserves relates to increased estimates for indemnity and defense costs. The increase in property and casualty environmental reserves was primarily associated with updated estimates of site investigation and remedial costs with respect to existing sites and newly identified sites.

As a result of the comprehensive external study completed in the third quarter of 2017, AFG’s property and casualty insurance segment recorded an $89 million pretax special charge to increase its asbestos reserves by $53 million (net of reinsurance) and its environmental reserves by $36 million (net of reinsurance). The increase in property and casualty asbestos reserves reflects increasing life expectancies in the U.S., which have allowed more time for the impacts of asbestos exposure to emerge. AFG’s comprehensive external study incorporates, among other factors, the increase in projected industry ultimate losses attributable to asbestos exposures, as well as revised estimates for future claims emergence. The increase in property and casualty environmental reserves was attributed primarily to increased legal defense costs and a number of claims and sites where the estimated investigation and remediation costs have increased.

Contingencies related to Subsidiaries’ Former Operations   The A&E studies and reviews discussed above encompassed reserves for various environmental and occupational injury and disease claims and other contingencies arising out of the railroad operations disposed of by American Premier’s predecessor and certain manufacturing operations disposed of by American Premier and its subsidiaries and by Great American Financial Resources, Inc. Charges resulting from the A&E study and reviews were $11 million in 2019, $9 million in 2018 and $24 million in 2017. For a discussion of the charges recorded for those operations, see “Results of Operations — Holding Company, Other and Unallocated.” Liabilities for claims and contingencies arising from these former railroad and manufacturing operations totaled $91 million at December 31, 2019. For a discussion of the uncertainties in determining the ultimate liability, see Note N — “Contingencies” to the financial statements.

Indexed Annuity Embedded Derivatives   As of December 31, 2019, annuity benefits accumulated in AFG’s Balance Sheet includes $3.73 billion for the fair value of the derivatives embedded in its fixed-indexed and variable-indexed annuities. As discussed in Note F — “Derivatives” to the financial statements, AFG’s fixed-indexed and variable-indexed annuities provide policyholders with a crediting rate tied, in part, to the performance of an existing stock market or other financial index. Under GAAP, this index participation is considered an embedded derivative that is required to be carried at fair value in the financial statements. AFG attempts to mitigate the risk in the index-based component of these products through the purchase and sale of call and put options on the appropriate index. AFG’s strategy is designed so that the net change in the fair value of the call option assets and put option liabilities will generally offset the economic change in the net liability from the index participation. The fair value of the embedded derivatives represents an estimate of the present value of projected policyholder benefits from the equity participation in excess of the projected minimum guaranteed contract values. As discussed in Note D — “Fair Value Measurements” to the financial statements, the fair value of the embedded derivatives is impacted by fluctuations in interest rates, the stock market (including the cost of options), policyholder behavior and other factors. Fluctuations in certain of these factors, such as changes in interest rates and the performance of the stock market, are not economic in nature for the current reporting period, but rather impact the timing of reported results.

Run-off Long-term Care Insurance   In December 2015, AFG completed the sale of United Teacher Associates Insurance Company and Continental General Insurance Company, the legal entities containing substantially all of its run-off long-term care insurance business, to HC2 Holdings, Inc. (“HC2”) for approximately $13 million in net proceeds. AFG may also receive up to $13 million of additional proceeds from HC2 in 2020 contingent upon the release of certain statutory-basis liabilities of the legal entities sold by AFG. In connection with obtaining regulatory approval for the transaction, AFG agreed to provide up to an aggregate of $35 million of capital support for the insurance companies, on an as-needed basis to maintain specified surplus levels, subject to immediate reimbursement by HC2 through a five-year capital maintenance agreement expiring in 2020. With the completion of this sale, AFG divested substantially all of its long-term care business (96% as measured by net statutory reserves as of November 30, 2015) and retained only a small block of long-term care insurance (1,500 policies) with approximately $48 million of reserves at December 31, 2019. AFG will continue to accept renewal premiums on its remaining outstanding policies, which are guaranteed renewable.

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 H — “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 attributable to shareholders, determined in accordance with GAAP, include certain items that may not be indicative of its ongoing core operations. For example, 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. Similarly, significant gains and losses from the sale of real estate are excluded from core earnings as they are influenced by the timing of sales and realized gains (losses) and significant tax benefits (charges) related to subsidiaries are excluded because such gains and losses are largely the result of the changing business strategy and market opportunities. In addition, special charges related to coverage that AFG no longer writes, such as the Neon exited lines and for asbestos and environmental exposures are excluded from core earnings.

Beginning prospectively with the second quarter of 2019, AFG’s core net operating earnings for its annuity segment excludes unlocking, the impact of changes in the fair value of derivatives related to fixed-indexed annuities (“FIAs”), and other impacts of changes in the stock market and interest rates on the accounting for FIAs over or under the cost of the equity index options purchased to mitigate the risk in the index-based component of those FIAs (“annuity non-core earnings (losses)”). Fluctuations in interest rates and the stock market, among other factors, can cause volatility in the periodic measurement of FIA liabilities that management believes can be inconsistent with the long-term economics of this growing portion of AFG’s annuity business. Management believes that separating these impacts as “non-core” will provide investors with a better view of the fundamental performance of the business, and a more comparable measure of the annuity segment’s business compared to the results identified as “core” by its peers. Core net operating earnings for the annuity segment for the first quarter of 2019 and prior periods were not adjusted, so results for periods following the change are not directly comparable to prior periods. The impact of the items now considered annuity non-core earnings on prior periods is highlighted in the discussion following the reconciliation of net earnings attributable to shareholders to core net operating earnings.

55

The following table (in millions, except per share amounts) identifies non-core items and reconciles net earnings attributable to shareholders 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.

(*) As discussed above, beginning prospectively with the second quarter of 2019, unlocking, the impact of changes in the fair value of derivatives related to FIAs, and other impacts of changes in the stock market and interest rates on the accounting for FIAs over or under the cost of the equity index options purchased to mitigate the risk in the index-based component of those FIAs are considered annuity non-core earnings (losses).

AFG reported net earnings attributable to shareholders of $211 million in the fourth quarter of 2019 compared to a net loss attributable to shareholders of $29 million in the fourth quarter of 2018. Results for the fourth quarter of 2019 were positively impacted by $8 million in net non-core items. Comparatively, the net loss in the 2018 fourth quarter includes $188 million in non-core net realized losses on securities. In addition, net earnings attributable to shareholders includes after-tax earnings of $19 million in the fourth quarter of 2019 and after-tax losses of $52 million in the fourth quarter of

2018 from unlocking (in the 2018 quarter), the impact of changes in the fair value of derivatives related to FIAs and other impacts of changes in the stock market and interest rates on the accounting for FIAs over or under the cost of the equity index options purchased to mitigate the risk in the index-based component of those FIAs. As discussed above, this impact on the accounting for FIAs is considered non-core earnings (losses) beginning prospectively with the second quarter of 2019. Excluding the $52 million after-tax negative impact of these items on results for the fourth quarter of 2018, core net operating earnings decreased $8 million in the fourth quarter of 2019 compared to the same period in 2018 reflecting lower earnings in the property and casualty insurance segment and higher holding company expenses, partially offset by higher earnings in the annuity segment. Realized gains (losses) on securities in the fourth quarters of 2019 and 2018 resulted primarily from the change in fair value of equity securities that were still held at the balance sheet date.

Net earnings attributable to shareholders increased $367 million for the full-year of 2019 compared to the same period in 2018 due primarily to after-tax net realized gains on securities of $227 million in 2019 compared to after-tax net realized losses of $210 million in 2018. In addition, net earnings attributable to shareholders includes an after-tax loss of $38 million for the full-year of 2019 (after tax losses of $9 million in the first quarter, $27 million in the second quarter and $21 million in the third quarter, and an after tax gain of $19 million in the fourth quarter) and an after-tax loss of $38 million for the full-year of 2018 from unlocking, the impact of changes in the fair value of derivatives related to FIAs, and other impacts of changes in the stock market and interest rates on the accounting for FIAs over or under the cost of the equity index options purchased to mitigate the risk in the index-based component of those FIAs. As discussed above, this impact on the accounting for FIAs is considered non-core earnings (losses) beginning prospectively with the second quarter of 2019. Excluding the $9 million after-tax negative impact of these items on results for the first quarter of 2019 and the $38 million after-tax negative impact of these items on results for the full-year of 2018, core net operating earnings decreased $6 million in 2019 compared to 2018 reflecting higher holding company expenses, partially offset by higher earnings in the property and casualty insurance segment. Realized gains (losses) on securities in 2019 and 2018 resulted primarily from the change in fair value of equity securities that were still held at the balance sheet date.

Net earnings attributable to shareholders increased $55 million for the full-year of 2018 compared to the same period in 2017 due primarily to higher core net operating earnings, lower special A&E charges recorded in 2018 compared to 2017, losses on the retirement of debt in 2017 and the 2017 tax expense related to the change in the U.S. corporate tax rate, partially offset by net realized losses on securities in 2018 compared to net realized gains on securities in 2017, the 2017 favorable development in the Neon exited lines in connection with a reinsurance to close transaction and the 2017 tax benefit from restructuring at Neon. Core net operating earnings increased $173 million in 2018 compared to 2017 reflecting higher net investment income in the property and casualty insurance segment, lower interest charges on borrowed money, lower holding company expenses and a lower corporate income tax rate, partially offset by lower earnings in the annuity segment and income from the sale of real estate in 2017. Realized losses on securities in 2018 includes the decline in fair value of equity securities that are required to be carried at fair value through net earnings under accounting guidance adopted on January 1, 2018. Included in the $210 million of non-core net realized losses on securities in 2018 were $214 million in net losses on equity securities that AFG continued to own at December 31, 2018.

RESULTS OF OPERATIONS — QUARTERS ENDED DECEMBER 31, 2019 AND 2018

Segmented Statement of Earnings   

AFG reports its business as three segments: (i) Property and casualty insurance (“P&C”), (ii) Annuity and (iii) Other, which includes run-off long-term care and life, holding company costs and income and expenses related to the managed investment entities (“MIEs”).

AFG’s net earnings attributable to shareholders, 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 December 31, 2019 and 2018 identify such items by segment and reconcile net earnings attributable to shareholders 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 LAE, 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 $121 million in GAAP pretax earnings in the fourth quarter of 2019 compared to $208 million in the fourth quarter of 2018, a decrease of $87 million (42%). Property and casualty core pretax earnings were $197 million in the fourth quarter of 2019 compared to $208 million in the fourth quarter of 2018, a decrease of $11 million (5%). The decrease in GAAP and core pretax earnings reflects lower underwriting profit, partially offset by higher net investment income in the fourth quarter of 2019 compared to the fourth quarter of 2018.

59

GAAP pretax earnings also includes a pretax non-core charge of $76 million in the fourth quarter of 2019 related to costs associated with plans to exit the Lloyd’s of London insurance market in 2020. See “Neon exited lines charge” below.

The following table details AFG’s GAAP and core earnings before income taxes from its property and casualty insurance operations for the three months ended December 31, 2019 and 2018 (dollars in millions):

Underwriting expense ratio	32.5		%	29.3		%	3.2	%

(a) Excludes a pretax non-core charge of $46 million (3.3 points on the combined ratio) in the fourth quarter of 2019 associated with plans to exit the Lloyd’s of London insurance market in 2020.

(b) Excludes a pretax non-core charge of $30 million (2.2 points on the combined ratio) in the fourth quarter of 2019 associated with plans to exit the Lloyd’s of London insurance market in 2020.

Starting in 1986, AFG’s statutory combined ratio has been better than the U.S. industry average for 32 of the 34 years. Management believes that AFG’s insurance operations have performed better than the industry as a result of its specialty niche focus, product line diversification, stringent underwriting discipline and alignment of compensation incentives.

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

Gross written premiums (“GWP”) for AFG’s property and casualty insurance segment were $1.75 billion for the fourth quarter of 2019 compared to $1.61 billion for the fourth quarter of 2018, an increase of $136 million (8%). Detail of AFG’s property and casualty gross written premiums is shown below (dollars in millions):

The $136 million (8%) increase in gross written premiums in the fourth quarter of 2019 compared to the fourth quarter of 2018 reflects growth in the Specialty casualty and Specialty financial sub-segments, partially offset by lower premiums in

61

the Property and transportation sub-segment. Overall average renewal rates increased approximately 5% in the fourth quarter of 2019. Excluding rate decreases in the workers’ compensation business, renewal pricing increased approximately 7%.

Property and transportation Gross written premiums decreased $23 million (4%) in the fourth quarter of 2019 compared to the fourth quarter of 2018. Higher premiums in the property and inland marine and ocean marine businesses were more than offset by lower premiums in the transportation businesses (due primarily to the timing of the renewal of a large commercial auto account) and lower year-over-year premiums related to winter wheat and rainfall index products in the crop operations. Average renewal rates increased nearly 5% for this group in the fourth quarter of 2019. Reinsurance premiums ceded as a percentage of gross written premiums decreased 2 percentage points for the fourth quarter of 2019 compared to the fourth quarter of 2018, reflecting lower cessions in the crop insurance business.

Specialty casualty Gross written premiums increased $151 million (19%) in the fourth quarter of 2019 compared to the fourth quarter of 2018. Growth in the surplus lines and excess liability businesses, primarily the result of new business opportunities, rate increases and higher retentions on renewal business, were primary drivers of the higher premiums. Higher premiums reported by Neon, premium growth in the executive liability business and the addition of ABA Insurance Services also contributed to the increase in premiums. Average renewal rates for this group increased approximately 6% in the fourth quarter of 2019. Excluding rate decreases in the workers’ compensation business, renewal rates for this group increased approximately 11%. Reinsurance premiums ceded as a percentage of gross written premiums increased 3 percentage points for the fourth quarter of 2019 compared to the fourth quarter of 2018, reflecting growth in the surplus lines, excess liability and mergers and acquisitions businesses, which have a higher ceding percentage than the overall Specialty casualty sub-segment.

Specialty financial Gross written premiums increased $8 million (4%) in the fourth quarter of 2019 compared to the fourth quarter of 2018, due to modest growth across all businesses in the group. Average renewal rates for this group increased approximately 2% in the fourth quarter of 2019. Reinsurance premiums ceded as a percentage of gross written premiums decreased 4 percentage points for the fourth quarter of 2019 compared to the fourth quarter of 2018 reflecting lower cessions in the financial institutions business due to reduced gross written premiums in certain lines of business that are 100% reinsured.

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 $2 million (5%) in the fourth quarter of 2019 compared to the fourth quarter of 2018, reflecting an increase in premiums retained, primarily from businesses in the Specialty casualty sub-segment.

Combined Ratio

Performance measures such as the combined ratio are often used by property and casualty insurers to help users of their financial statements better understand the company’s performance. The combined ratio is the sum of the loss and loss adjustment expenses (“LAE”) and underwriting expense ratios. These ratios are calculated by dividing each of the respective expenses by net earned premiums. The table below (dollars in millions) details the components of the combined ratio for AFG’s property and casualty insurance segment:

	Three months ended December 31,						Three months ended December 31,
	2019		2018		Change		2019			2018

The Specialty property and casualty insurance operations generated an underwriting profit of $89 million for the fourth quarter of 2019 compared to $102 million in the fourth quarter of 2018, a decrease of $13 million (13%). Lower underwriting results in the Property and transportation sub-segment were partially offset by higher underwriting profits in the Specialty casualty and Specialty financial sub-segments. Overall catastrophe losses were $15 million, including $1 million of net reinstatement premiums, (1.0 points on the combined ratio) in the fourth quarter of 2019 compared to $38 million, including a $1 million favorable adjustment to net reinstatement premiums, (3.0 points) in the fourth quarter of 2018.

Property and transportation This group reported an underwriting loss of $2 million for the fourth quarter of 2019 compared to an underwriting profit of $64 million in the fourth quarter of 2018, a change of $66 million (103%). Record levels of prevented planting claims in the crop operations were the driver of the lower underwriting results in the fourth quarter of 2019 compared to the fourth quarter of 2018. Catastrophe losses for this group were $7 million in the fourth quarter of 2019. By comparison, catastrophe losses had a favorable impact of $1 million in the 2018 fourth quarter, with catastrophe losses reported from the previous quarter developing favorably in the fourth quarter of 2018.

63

Specialty casualty Underwriting profit for this group was $69 million for the fourth quarter of 2019 compared to $22 million for the fourth quarter of 2018, an increase of $47 million (214%). This increase is largely due to a reduction in the underwriting loss at Neon (excluding the Neon exited lines charge), due primarily to lower year-over-year catastrophe losses. See “Neon exited lines charge” below for information about AFG’s plans to exit the Lloyd’s of London insurance market in 2020. Higher underwriting profit in the workers’ compensation businesses, due primarily to higher favorable prior year reserve development, also contributed to the increase in underwriting profit between periods. Catastrophe losses were $5 million (0.8 points on the combined ratio) for the fourth quarter of 2019 compared to $28 million (4.7 points) for the fourth quarter of 2018. Catastrophe losses in both periods were primarily in the Neon operations.

Specialty financial Underwriting profit for this group was $32 million for the fourth quarter of 2019 compared to $20 million in the fourth quarter of 2018, an increase of $12 million (60%). Higher underwriting profits in the financial institutions, surety and trade credit businesses contributed to these results. Catastrophe losses were $2 million (1.1 points on the combined ratio) in the fourth quarter of 2019 compared to $10 million (7.1 points) in the fourth quarter of 2018.

Other specialty This group reported an underwriting loss of $10 million for the fourth quarter of 2019 compared to $4 million in the fourth quarter of 2018, an increase of $6 million (150%), 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 fourth quarter of 2019 compared to the fourth quarter of 2018.

Neon exited lines charge In December 2019, AFG initiated actions to exit the Lloyd’s of London insurance market, which included placing its Lloyd’s subsidiaries including its Lloyd’s Managing Agency, Neon Underwriting Ltd., into run-off and recording a non-core charge of $76 million for reserve strengthening and expenses related to exit costs incurred with the run-off of this business. Neon and its predecessor, Marketform, have failed to achieve AFG’s profitability objectives since AFG’s purchase of Marketform in 2008. The non-core charge includes $46 million to increase loss reserves (including $7 million of net adverse prior year reserve development) and $30 million of underwriting expenses representing contractual employee severance benefits and other incurred exit costs. AFG will incur additional employee-related, rent and other expenses as the business is run-off.

In the fourth quarter of 2017, Neon entered into a reinsurance to close agreement for its 2015 and prior years of account, which transfers the responsibility for all of the liabilities that attach to the transferred year of account as well as any income due to the closing year of account in return for a premium. As a result of the reinsurance to close agreement, Neon recorded favorable reserve development of $42 million, of which $24 million related to its ongoing lines of business (included in Specialty casualty) and $18 million related to exited lines of business (included in Neon exited lines charge).

Consistent with the treatment of other items that are not indicative of AFG’s ongoing operations (both favorable and unfavorable), the $76 million charge related to the Neon exited lines recorded in 2019 in connection with AFG’s plans to exit the Lloyd’s of London insurance market in 2020 and the $18 million of favorable development related to the Neon exited lines recorded in connection with the December 2017 reinsurance to close transaction were treated as non-core.

Aggregate Aggregate underwriting results for AFG’s property and casualty insurance segment for the fourth quarter of 2019 includes the Neon exited lines charge mentioned above.

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 66.0% for the fourth quarter of 2019 compared to 64.4% for the fourth quarter of 2018, an increase of 1.6 percentage points.

Property and transportation   The 10.0 percentage points increase in the loss and LAE ratio for the current year, excluding catastrophe losses reflects an increase in the loss and LAE ratio of the crop operations due to a high level of prevented planting claims resulting from excess rain in 2019.

Specialty casualty   The 4.9 percentage points decrease in the loss and LAE ratio for the current year, excluding catastrophe losses reflects a decrease in the loss and LAE ratio at Neon (excluding the impact of the Neon exited lines charge), partially offset by an increase in the loss and LAE ratio of the workers’ compensation businesses.

Specialty financial   The 0.3 percentage points decrease in the loss and LAE ratio for the current year, excluding catastrophe losses reflects a decrease in the loss and LAE ratio of the financial institutions business, partially offset by an increase in the loss and LAE ratio of the fidelity business.

65

Net prior year reserve development

AFG’s Specialty property and casualty insurance operations recorded net favorable reserve development related to prior accident years of $53 million in the fourth quarter of 2019 compared to $61 million in the fourth quarter of 2018, a decrease of $8 million (13%).

Property and transportation   Net favorable reserve development of $18 million in the fourth quarter of 2019 reflects lower than expected claim frequency at National Interstate and lower than anticipated claim severity in the property and inland marine business. Net favorable reserve development of $7 million in the fourth quarter of 2018 reflects lower than expected claim frequency and severity at National Interstate and lower than expected losses in the crop business.

Specialty casualty   Net favorable reserve development of $25 million in the fourth quarter of 2019 reflects lower than anticipated claim frequency and severity in the workers’ compensation businesses, partially offset by higher than expected claim severity in the excess and surplus lines businesses, higher than expected claim frequency in product liability contractor claims, and higher than anticipated claim severity in the public sector business. Net favorable reserve development of $52 million in the fourth quarter of 2018 reflects lower than anticipated claim severity in the workers’ compensation businesses and lower than expected emergence in assumed 2017 property catastrophe losses at Neon.

Specialty financial   Net favorable reserve development of $14 million in the fourth quarter of 2019 reflects lower than expected claim frequency and severity in the surety business and lower than anticipated claim severity in the foreign credit business. Net favorable reserve development of $7 million in the fourth quarter of 2018 reflects lower than expected claim frequency and severity in the surety business and lower than anticipated claim frequency in run-off businesses.

Other specialty In addition to the development discussed above, total Specialty prior year reserve development includes net adverse reserve development of $4 million in the fourth quarter of 2019 and $5 million in the fourth quarter of 2018, reflecting adverse development associated with AFGs internal reinsurance program, partially offset by the amortization of deferred gains on the retroactive reinsurance transactions entered into in connection with the sale of businesses in 1998 and 2001.

Aggregate Aggregate net prior accident years reserve development for AFG’s property and casualty insurance segment for the fourth quarter of 2019 includes $7 million of net adverse reserve development related to Neon exited lines discussed above under “Neon exited lines charge.”

Catastrophe losses

AFG generally seeks to reduce its exposure to catastrophes through individual risk selection, including minimizing coastal and known fault-line exposures, and the purchase of reinsurance. Based on data available at December 31, 2019, 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	1%
250-year event	2%
500-year event	6%

As of January 1, 2020, AFG maintains comprehensive catastrophe reinsurance coverage, including a $15 million per occurrence net retention for its U.S.-based property and casualty insurance operations for losses up to $134 million. Neon’s excess of loss catastrophe reinsurance limits the maximum retained loss per event to $15 million for losses up to $145 million on direct business and $15 million for losses up to $45 million on assumed business. AFG’s property and casualty insurance operations further maintain supplemental fully collateralized reinsurance coverage up to 95% of $200 million for catastrophe losses in excess of $134 million of traditional catastrophe reinsurance through a catastrophe bond.

Catastrophe losses of $14 million in the fourth quarter of 2019 resulted primarily from Typhoons Faxai and Hagibis, storms and tornadoes in the south-central United States and the Kincade fire in California. Catastrophe losses of $39 million in the fourth quarter of 2018 resulted primarily from Hurricane Michael and wildfires in California.

Commissions and Other Underwriting Expenses

AFG’s property and casualty commissions and other underwriting expenses (“U/W Exp”) were $446 million in the fourth quarter of 2019 compared to $372 million for the fourth quarter of 2018, an increase of $74 million (20%). AFG’s underwriting expense ratio, calculated as commissions and other underwriting expenses divided by net premiums earned, was 32.5% for the fourth quarter of 2019 compared to 29.3% for the fourth quarter of 2018, an increase of 3.2 percentage points. Detail of AFG’s property and casualty commissions and other underwriting expenses and underwriting expense ratios is shown below (dollars in millions):

	Three months ended December 31,
	2019				2018				Change in
	U/W Exp		% of NEP		U/W Exp		% of NEP		% of NEP

Total Aggregate	$	446	32.5	%	$	372	29.3	%	3.2	%

Property and transportation   Commissions and other underwriting expenses as a percentage of net earned premiums increased 4.3 percentage points in the fourth quarter of 2019 compared to the fourth quarter of 2018 reflecting lower profitability-based ceding commissions received from reinsurers in the crop business and growth in businesses that have higher underwriting expense ratios than many of the businesses in the Property and transportation sub-segment.

Specialty casualty   Commissions and other underwriting expenses as a percentage of net earned premiums decreased 2.7 percentage points in the fourth quarter of 2019 compared to the fourth quarter of 2018 reflecting the impact of higher premiums on the ratio, particularly in the excess and surplus lines businesses.

Specialty financial   Commissions and other underwriting expenses as a percentage of net earned premiums increased 4.4 percentage points in the fourth quarter of 2019 compared to the fourth quarter of 2018 reflecting higher profitability-based commissions paid to agents in the financial institutions business, higher underwriting expenses in the European businesses, due to costs incurred in preparation for Brexit, and a change in the mix of business.

Aggregate   Aggregate commissions and other underwriting expenses for AFG’s property and casualty insurance segment includes $30 million of underwriting expenses related to the Neon exited lines charge in the fourth quarter of 2019 representing contractual employee severance benefits and other incurred exit costs. See “Neon exited lines charge” above for information about AFG’s plans to exit the Lloyd’s of London insurance market in 2020.

Property and Casualty Net Investment Income

Net investment income in AFG’s property and casualty insurance operations was $120 million in the fourth quarter of 2019 compared to $115 million in the fourth quarter of 2018, an increase of $5 million (4%). 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 December 31,									%
	2019			2018			Change			Change
Net investment income	$	120		$	115		$	5		4	%

Tax equivalent yield (*)	4.22		%	4.49		%	(0.27		%)

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

The increase in net investment income in the property and casualty insurance segment for the fourth quarter of 2019 as compared to the fourth quarter of 2018 reflects growth in the property and casualty insurance segment, partially offset by lower income from partnerships and similar investments. The property and casualty insurance segment’s overall yield on investments (net investment income as a percentage of average invested assets) was 4.09% for the fourth quarter of

67

2019 compared to 4.32% for the fourth quarter of 2018, a decrease of 0.23 percentage points, reflecting a lower yield on partnerships and similar investments. AFG’s property and casualty insurance operations recorded $18 million in earnings from partnerships and similar investments and AFG-managed CLOs in the fourth quarter of 2019 compared to $22 million in the fourth quarter of 2018, a decrease of $4 million (18%). The annualized yield earned on these investments was 9.1% in the fourth quarter of 2019 compared to 13.8% 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 $11 million for the fourth quarter of 2019 compared to $8 million for the fourth quarter of 2018, an increase of $3 million (38%).

Annuity Segment — Results of Operations

AFG’s annuity operations contributed $128 million in GAAP pretax earnings in the fourth quarter of 2019 compared to $20 million in the fourth quarter of 2018, an increase of $108 million (540%). This increase in AFG’s GAAP annuity segment results for the fourth quarter of 2019 as compared to the fourth quarter of 2018 is due primarily to the favorable impact of the significant increase in stock market performance on annuities with guaranteed withdrawal benefits and on the fair value of derivatives related to FIAs in the fourth quarter of 2019 compared to the unfavorable impact of the significant decline in the stock market on these annuities in the fourth quarter of 2018. The increase in pretax earnings also reflects growth in the annuity business. AFG monitors the major actuarial assumptions underlying its annuity operations throughout the year and has historically conducted detailed reviews (“unlocking”) of its assumptions in the fourth quarter of each year. Beginning with the third quarter of 2019, AFG moved its annual unlocking to the third quarter and expects to continue to conduct the annual review in the third quarter of each year (consistent with many of its peers). The unlocking of the actuarial assumptions resulted in a net charge to earnings of $4 million in the fourth quarter of 2018. If changes in the economic environment or actual experience would cause material revisions to future estimates, these assumptions are updated (unlocked) in an interim quarter.

The following table details AFG’s GAAP and core earnings before income taxes from its annuity operations for the three months ended December 31, 2019 and 2018 (dollars in millions):

	Three months ended December 31,
	2019		2018		% Change
Revenues:
Net investment income	$	458	$	419	9	%
Other income:
Guaranteed withdrawal benefit fees	17		17		—	%

Total revenues	484		446		9	%
Costs and Expenses:
Annuity benefits (a)(b)	281		334		(16	%)
Acquisition expenses (a)	65		56		16	%

Pretax non-core earnings (losses) (a)	24		—		—	%
GAAP earnings before income taxes	$	128	$	20	540	%

(a) As discussed under “Results of Operations — General,” beginning prospectively with the second quarter of 2019, unlocking, the impact of changes in the fair value of derivatives related to FIAs, and other impacts of changes in the stock market and interest rates on the accounting for FIAs over or under the cost of the equity index options purchased to mitigate the risk in the index-based component of those FIAs are considered non-core earnings (losses). For the fourth quarter of 2019, annuity benefits exclude the $30 million favorable impact of these items and acquisition expenses exclude the related $6 million unfavorable impact on the amortization of deferred policy acquisition costs.

(b) Details of the components of annuity benefits are provided below.

69

Annuity core earnings before income taxes were $104 million in the fourth quarter of 2019 compared to $20 million in the fourth quarter of 2018, an increase of $84 million (420%). As discussed under “Results of Operations — General,” beginning prospectively with the second quarter of 2019, unlocking, changes in the fair value of derivatives related to FIAs, and other impacts of changes in the stock market and interest rates on the accounting for FIAs over or under the cost of the equity index options purchased to mitigate the risk in the index-based component of those FIAs are considered non-core earnings (losses). For the fourth quarter of 2019, the annuity segment’s core earnings before income taxes excludes $24 million in pretax earnings related to these items. Since annuity core earnings for the first quarter of 2019 and prior periods were not adjusted, the annuity segment’s core earnings before income taxes for the fourth quarter of 2018 includes the $66 million negative impact from these items in that period. Excluding the $66 million negative impact of these items on results for the fourth quarter of 2018, annuity core earnings before income taxes were $18 million (21%) higher in the fourth quarter of 2019 compared to the fourth quarter of 2018, reflecting growth in the annuity business. The table below highlights the impact of unlocking, changes in the fair value of derivatives and other impacts of the changes in the stock market and interest rates on annuity segment results (dollars in millions):

Because fluctuations in interest rates and the stock market, among other factors, can cause volatility in annuity benefits expense related to FIAs that can be inconsistent with the long-term economics of the FIA business, management believes that including the actual cost of the equity options purchased in the FIA business and excluding unlocking, the impact of changes in the fair value of derivatives related to FIAs, and other impacts of changes in the stock market and interest rates on the accounting for FIAs provides investors with a better view of the true cost of funds in the business and a more comparable measure to the cost of funds reported by its peers. The cost of the equity options included in AFG’s cost of funds is the net purchase price of the option contracts amortized on a straight-line basis over the life of the contracts, which is generally one year. The following table reconciles AFG’s non-GAAP cost of funds measure to total annuity benefits expense (in millions):

	Three months ended December 31,

See “Annuity Unlocking” below for a discussion of the impact that the unlocking of actuarial assumptions had on annuity benefits expense in the fourth quarter of 2018.

Net Spread on Fixed Annuities (excludes variable annuity earnings)

The profitability of a fixed annuity business is largely dependent on the ability of a company to earn income on the assets supporting the business in excess of the amounts credited to policyholder accounts plus expenses incurred (earning a “spread”). Performance measures such as net interest spread and net spread earned are often presented by annuity businesses to help users of their financial statements better understand the company’s performance.

71

The table below (dollars in millions) details the components of these spreads for AFG’s fixed annuity operations (including fixed-indexed and variable-indexed annuities):

	Three months ended December 31,						%
	2019			2018			Change
Average fixed annuity investments (at amortized cost)	$	39,316		$	35,993		9	%
Average fixed annuity benefits accumulated	39,615			36,103			10	%
As % of fixed annuity benefits accumulated (except as noted):
Net investment income (as % of fixed annuity investments)	4.63		%	4.64		%
Cost of funds	(2.54		%)	(2.58		%)
Other annuity benefit expenses, net of guaranteed withdrawal benefit fees (*)	(0.11		%)	(0.12		%)
Net interest spread	1.98		%	1.94		%
Policy charges and other miscellaneous income (*)	0.07		%	0.08		%
Acquisition expenses (*)	(0.65		%)	(0.66		%)
Other expenses	(0.33		%)	(0.38		%)

Changes in fair value of derivatives related to FIAs and other impacts of the stock market and interest rates under (over) option costs	0.24		%	(0.69		%)
Unlocking	—		%	(0.04		%)
Net spread earned on fixed annuities	1.31		%	0.25		%

(*) Excluding unlocking, the impact of changes in the fair value of derivatives related to FIAs, and other impacts of changes in the stock market and interest rates on annuity benefits and the related impact on the amortization of deferred policy acquisition costs.

Annuity Net Investment Income

Net investment income for the fourth quarter of 2019 was $458 million compared to $419 million for the fourth quarter of 2018, an increase of $39 million (9%). This increase reflects the growth in AFG’s annuity business and higher earnings on investments accounted for under the equity method. The overall yield earned on investments in AFG’s fixed annuity operations, calculated as net investment income divided by average investment balances (at amortized cost), decreased by 0.01 percentage points to 4.63% from 4.64% in the fourth quarter of 2019 compared to the fourth quarter of 2018. The impact of the reinvestment of proceeds from maturity and redemption of higher yielding investments at the lower yields available in the financial markets was substantially offset by very strong investment income in the 2019 quarter, including higher yields on investments accounted for under the equity method. For the period from October 1, 2018 through December 31, 2019, $6.4 billion in annuity segment investments with an average yield of approximately 5.0% were redeemed or sold with the proceeds reinvested at an approximately 0.8% lower yield.

72

Annuity Cost of Funds

Cost of funds for the fourth quarter of 2019 was $252 million compared to $233 million for the fourth quarter of 2018, an increase of $19 million (8%), reflecting growth in the annuity business. The average cost of policyholder funds, calculated as cost of funds divided by average fixed annuity benefits accumulated, decreased 0.04 percentage points to 2.54% in the fourth quarter of 2019 from 2.58% in the fourth quarter of 2018 reflecting lower renewal option costs.

The following table provides details of AFG’s interest credited and other cost of funds (in millions):

	Three months ended December 31,
	2019		2018
Cost of equity options (FIAs)	$	150	$	141
Interest credited:
Traditional fixed annuities	62		58

Immediate annuities	6		6
Pension risk transfer products	3		1
Federal Home Loan Bank advances	6		6
Total cost of funds	$	252	$	233

Other Annuity Benefits, Net of Guaranteed Withdrawal Benefit Fees

Other annuity benefits, net of guaranteed withdrawal benefit fees excluding the impact of unlocking and the stock market and interest rates, for the fourth quarter of 2019 were $11 million compared to $10 million for the fourth quarter of 2018, an increase of $1 million (10%). As a percentage of average fixed annuity benefits accumulated, these net expenses decreased 0.01 percentage points to 0.11% from 0.12% in the fourth quarter of 2019 compared to the fourth quarter of 2018. In addition to interest credited to policyholders’ accounts and the change in fair value of derivatives related to fixed-indexed annuities, annuity benefits expense also includes the following expenses (in millions, net of guaranteed withdrawal benefit fees):

	Three months ended December 31,
	2019			2018
Other annuity benefits, excluding the impact of the stock market and interest rates on FIAs:
Amortization of sales inducements	$	3		$	5

Other annuity benefits excluding the impact of the stock market and interest rates, net	11			10
Other annuity benefits — impact of the stock market and interest rates	2			35
Other annuity benefits, net	$	13		$	45

As discussed under “Annuity Benefits Accumulated” in Note A — “Accounting Policies” to the financial statements, guaranteed withdrawal benefit reserves are accrued for and modified using assumptions similar to those used in establishing and amortizing deferred policy acquisition costs. In addition, the guaranteed withdrawal benefit reserve related to FIAs can be inversely impacted by the calculated FIA embedded derivative reserve as the value to policyholders of the guaranteed withdrawal benefits decreases when the benefit of stock market participation increases. As shown in the table above, changes in the stock market and interest rates increased AFG’s guaranteed withdrawal benefit reserve by $2 million in the fourth quarter of 2019 compared to $35 million in the fourth quarter of 2018. This $33 million (94%) decrease was the primary cause of the $32 million overall decrease in other annuity benefits, net of guaranteed withdrawal benefit fees in the fourth quarter of 2019 compared to the fourth quarter of 2018.

See “Annuity Unlocking” below for a discussion of the impact that the unlocking of actuarial assumptions had on annuity benefits expense in the fourth quarter of 2018.

Annuity Net Interest Spread

AFG’s net interest spread increased 0.04 percentage points to 1.98% from 1.94% in the fourth quarter of 2019 compared to the same period in 2018 due primarily to lower renewal option costs. Features included in current annuity product offerings allow AFG to achieve its desired profitability at a lower net interest spread than historical product offerings. As a result, AFG expects its net interest spread to narrow in the future.

73

Annuity Policy Charges and Other Miscellaneous Income

Annuity policy charges and other miscellaneous income, which consist primarily of surrender charges, amortization of deferred upfront policy charges (unearned revenue) and income from sales of real estate were $9 million in the fourth quarter of 2019 compared to $10 million the fourth quarter of 2018, a decrease of $1 million (10%). Annuity policy charges and other miscellaneous income as a percentage of average fixed annuity benefits accumulated decreased 0.01 percentage points to 0.07% in the fourth quarter of 2019 from 0.08% in the fourth quarter of 2018.

See “Annuity Unlocking” below for a discussion of the impact that the periodic review of actuarial assumptions had on annuity policy charges and other miscellaneous income in the fourth quarter of 2018.

Annuity Acquisition Expenses

In addition to the impact of unlocking, the following table illustrates the acceleration/deceleration of the amortization of deferred policy acquisition costs (“DPAC”) resulting from changes in the fair value of derivatives related to FIAs and other impacts of changes in the stock market and interest rates on the accounting for FIAs over or under option costs (in millions):

	Three months ended December 31,
	2019		2018
Annuity acquisition expenses before the impact of changes in the fair value of derivatives related to FIAs and other impacts of the stock market and interest rates	$	65	$	64
Unlocking	—		(1		)
Impact of changes in the fair value of derivatives and other impacts of the stock market and interest rates	6		(7		)
Annuity acquisition expenses	$	71	$	56

Annuity acquisitions expenses before unlocking and the acceleration/deceleration of the amortization resulting from changes in the fair value of derivatives related to FIAs and other impacts of changes in the stock market and interest rates on the accounting for FIAs over or under option costs were $65 million for the fourth quarter of 2019 compared to $64 million for the fourth quarter of 2018, an increase of $1 million (2%), reflecting growth in the annuity business.

See “Annuity Unlocking” below for a discussion of the impact that the unlocking of actuarial assumptions had on annuity and supplemental insurance acquisition expenses in the fourth quarter of 2018. Unanticipated spread compression, decreases in the stock market, adverse mortality experience, and higher than expected lapse rates could lead to future write-offs of DPAC or the present value of future profits on business in force of companies acquired (“PVFP”).

The positive impact of strong market performance during the fourth quarter of 2019 on the fair value of derivatives and other liabilities related to FIAs resulted in a partially offsetting acceleration of the amortization of DPAC. The unfavorable impact of the significant decline in stock market performance during the fourth quarter of 2018 on the fair value of derivatives and other liabilities related to FIAs resulted in a partially offsetting deceleration of the amortization of DPAC.

The table below illustrates the impact of unlocking and the estimated impact of changes in the fair value of derivatives related to fixed-indexed annuities and other impacts of changes in the stock market and interest rates on FIAs on annuity acquisition expenses as a percentage of average fixed annuity benefits accumulated:

	Three months ended December 31,
	2019		2018
Before unlocking, the impact of changes in the fair value of derivatives related to FIAs and other impacts of the stock market and interest rates	0.65	%	0.66	%
Unlocking	—	%	(0.01	%)
Impact of changes in fair value of derivatives and other impacts of the stock market and interest rates	0.06	%	(0.07	%)
Annuity acquisition expenses as a % of fixed annuity benefits accumulated	0.71	%	0.58	%

Annuity Other Expenses  

Annuity other expenses were $34 million for the fourth quarter of 2019 compared to $36 million for the fourth quarter of 2018, a decrease of $2 million (6%). Annuity other expenses represent primarily general and administrative expenses, as well as selling and issuance expenses that are not deferred. As a percentage of average fixed annuity benefits accumulated, these expenses decreased 0.05 percentage points to 0.33% from 0.38% for the fourth quarter of 2019 as compared to the fourth quarter of 2018 due primarily to growth in the annuity business.

Change in Fair Value of Derivatives Related to Fixed-Indexed (Including Variable-Indexed) Annuities and Other Impacts of Changes in the Stock Market and Interest Rates on FIAs

AFG’s fixed-indexed (including variable-indexed) annuities provide policyholders with a crediting rate tied, in part, to the performance of an existing stock market or other financial index. AFG attempts to mitigate the risk in the index-based component of these products through the purchase and sale of call and put options on the appropriate index. AFG’s strategy is designed so that the net change in the fair value of the call option assets and put option liabilities will generally offset the economic change in the net liability from the index participation. Both the index-based component of the annuities (an embedded derivative) and the related call and put options are considered derivatives that must be adjusted for changes in fair value through earnings each period. The fair values of these derivatives are impacted by actual and expected stock market performance and interest rates as well as other factors. For a list of other factors impacting the fair value of the embedded derivative component of AFG’s annuity benefits accumulated, see Note D — “Fair Value Measurements” to the financial statements. Fluctuations in certain of these factors, such as changes in interest rates and the performance of the stock market, are not economic in nature for the current reporting period, but rather impact the timing of reported results.

As discussed above under “Other Annuity Benefits, Net of Guaranteed Withdrawal Benefit Fees” and “Annuity Acquisition Expenses,” the periodic accounting for DPAC and guaranteed withdrawal benefits related to FIAs is also impacted by changes in the stock market and interest rates. These impacts may be temporary in nature and not necessarily indicative of the long-term performance of the FIA business. The table below highlights the impact of changes in the fair value of derivatives related to FIAs and the other impacts of the stock market and interest rates (excluding the impact of the 2018 unlocking charge) over or under the cost of the equity index options (discussed above) on earnings before income taxes for the annuity segment (dollars in millions):

	Three months ended December 31,
	2019			2018			% Change
Change in the fair value of derivatives related to FIAs	$	(15	)	$	(80	)	(81	%)
Accretion of guaranteed minimum FIA benefits	(103		)	(94		)	10	%
Other annuity benefits	(2		)	(35		)	(94	%)
Less cost of equity options	150			141			6	%
Related impact on the amortization of DPAC	(6		)	6			(200	%)
Impact on annuity segment earnings before income taxes	$	24		$	(62	)	(139	%)

During the fourth quarter of 2019, the positive impact of strong stock market performance increased earnings before income taxes for the annuity segment by $24 million. During the fourth quarter of 2018, the negative impact of the significant decline in the stock market reduced the annuity segment’s earnings before income taxes by $62 million. As a percentage of average fixed annuity benefits accumulated, the impact of changes in the fair value of derivatives related to FIAs and other impacts of changes in the stock market and interest rates on the accounting for FIAs over or under the cost of the equity index options purchased to mitigate the risk in the indexed-based component of those FIAs was a net expense reduction of 0.24% in the fourth quarter of 2019 compared to a net expense of 0.69% in the fourth quarter of 2018.

The following table provides analysis of the primary factors impacting the change in the fair value of derivatives related to FIAs and the other impacts of the stock market and interest rates (excluding the impact of the 2018 unlocking charge) on the accounting for FIAs over or under the cost of the equity index options discussed above. Each factor is presented net of the estimated related impact on the amortization of DPAC (dollars in millions).

	Three months ended December 31,
	2019			2018			% Change
Changes in the stock market, including volatility	$	24		$	(57	)	(142	%)
Changes in interest rates higher (lower) than expected	(4		)	(4		)	—	%
Other	4			(1		)	(500	%)
Impact on annuity segment earnings before income taxes	$	24		$	(62	)	(139	%)

See “Annuity Unlocking” below for a discussion of the impact that the unlocking of actuarial assumptions had on the change in the fair value of the embedded derivative and other annuity liabilities in the fourth quarter of 2018.

Annuity Net Spread Earned on Fixed Annuities

AFG’s net spread earned on fixed annuities excluding the impact of unlocking, changes in the fair value of derivatives related to FIAs and other impacts of changes in the stock market and interest rates over or under option costs increased 0.09 percentage points to 1.07% from 0.98% in the fourth quarter of 2019 compared to the same period in 2018 due primarily to the 0.04 percentage points increase in AFG’s net interest spread discussed above and the impact of growth in the business over stable fixed expenses. AFG’s overall net spread earned on fixed annuities increased 1.06 percentage points to 1.31% in the fourth quarter of 2019 from 0.25% in the fourth quarter of 2018 due to the increase in AFG’s net interest spread, the impact of changes in the fair value of derivatives and other impacts of the stock market and interest rates on the accounting for FIAs discussed above and the impact of the 2018 unlocking discussed below under “Annuity Unlocking.”

Annuity Benefits Accumulated

Annuity premiums received and benefit payments are recorded as increases or decreases in annuity benefits accumulated rather than as revenue and expense. Increases in this liability for interest credited and other benefits are charged to expense and decreases for surrender and other policy charges are credited to other income.

For certain products, annuity benefits accumulated also includes reserves for accrued persistency and premium bonuses, excess benefits expected to be paid on future deaths and annuitizations (“EDAR”) and guaranteed withdrawal benefits. Annuity benefits accumulated also includes amounts advanced from the Federal Home Loan Bank of Cincinnati. The following table is a progression of AFG’s annuity benefits accumulated liability for the three months ended December 31, 2019 and 2018 (in millions):

	Three months ended December 31,
	2019			2018
Beginning fixed annuity reserves	$	39,212		$	35,774
Fixed annuity premiums (receipts)	1,134			1,476
Federal Home Loan Bank advances	—			225
Surrenders, benefits and other withdrawals	(829		)	(796		)
Interest and other annuity benefit expenses:
Cost of funds	252			233
Embedded derivative mark-to-market	276			(490		)
Change in other benefit reserves	(27		)	5
Unlocking	—			4
Ending fixed annuity reserves	$	40,018		$	36,431
Reconciliation to annuity benefits accumulated per balance sheet:
Ending fixed annuity reserves (from above)	$	40,018		$	36,431
Impact of unrealized investment gains	225			10
Fixed component of variable annuities	163			175
Annuity benefits accumulated per balance sheet	$	40,406		$	36,616

Annuity benefits accumulated includes a liability of $625 million at December 31, 2019 and $472 million at December 31, 2018 for guaranteed withdrawal benefits on annuities with features that allow the policyholder to take fixed periodic lifetime benefit payments that could exceed account value. As discussed above under “Other Annuity Benefits, Net of Guaranteed Withdrawal Benefit Fees” and “Annuity Acquisition Expenses,” the periodic accounting for DPAC and guaranteed withdrawal benefits related to FIAs is also impacted by changes in the stock market and interest rates.

76

Statutory Annuity Premiums

AFG’s annuity operations generated statutory premiums of $1.14 billion in the fourth quarter of 2019 compared to $1.48 billion in the fourth quarter of 2018, a decrease of $343 million (23%). The following table summarizes AFG’s annuity sales (dollars in millions):

	Three months ended December 31,
	2019		2018		% Change
Financial institutions single premium annuities — indexed	$	359	$	455	(21	%)
Financial institutions single premium annuities — fixed	270		142		90	%
Retail single premium annuities — indexed	170		392		(57	%)
Retail single premium annuities — fixed	25		27		(7	%)
Broker dealer single premium annuities — indexed	107		335		(68	%)
Broker dealer single premium annuities — fixed	9		4		125	%
Pension risk transfer	158		75		111	%
Education market — fixed and indexed annuities	36		46		(22	%)
Total fixed annuity premiums	1,134		1,476		(23	%)
Variable annuities	5		6		(17	%)
Total annuity premiums	$	1,139	$	1,482	(23	%)

Management attributes the 23% decrease in annuity premiums in the fourth quarter of 2019 compared to the fourth quarter of 2018 to the lower market interest rate environment. In response to the continued drop in market interest rates during 2019, AFG lowered crediting rates on several products, which has slowed annuity sales compared to 2018 levels.

Annuity Unlocking

AFG monitors the major actuarial assumptions underlying its annuity operations throughout the year and conducts detailed reviews (“unlocking”) of its assumptions annually. Beginning with the third quarter of 2019, AFG moved its unlocking from the fourth quarter to the third quarter and expects to continue to conduct the annual review in the third quarter each year (consistent with many of its peers). If changes in the economic environment or actual experience would cause material revisions to future estimates, these assumptions are updated (unlocked) in an interim quarter.

The unlocking of the major actuarial assumptions underlying AFG’s annuity operations in the fourth quarter of 2018 resulted in a net charge related to its annuity business of $4 million, which impacted AFG’s financial statements as follows (in millions):

	Three months ended December 31,
	2019 (*)		2018
Policy charges and other miscellaneous income:
Unearned revenue	$	—	$	—
Total revenues	—		—
Annuity benefits:
Fixed-indexed annuity embedded derivative	—		—
Guaranteed withdrawal benefit reserve	—		(1		)
Other reserves	—		5
Sales inducements asset	—		1
Total annuity benefits	—		5
Annuity and supplemental insurance acquisition expenses:
Deferred policy acquisition costs	—		(1		)
Total costs and expenses	—		4
Net charge	$	—	$	(4	)

(*) The detailed review of the major actuarial assumptions was conducted in the third quarter of 2019.

The net charge from unlocking annuity assumptions in the fourth quarter of 2018 reflects the favorable impact of an increase in projected net interest spreads on in-force business (due primarily to higher actual yields than previously anticipated), more than offset by a slight increase in projected expenses and the unfavorable impact of changes in projected policyholder annuitization and lapse behavior. Reinvestment rate assumptions are based primarily on 7-year and 10-year corporate bond yields.

Annuity Earnings before Income Taxes Reconciliation

The following table reconciles the net spread earned on AFG’s fixed annuities to overall annuity pretax earnings for the three months ended December 31, 2019 and 2018 (in millions):

	Three months ended December 31,
	2019			2018
Earnings on fixed annuity benefits accumulated	$	129		$	22
Earnings impact of investments in excess of fixed annuity benefits accumulated (*)	(3		)	(1		)
Variable annuity earnings (loss)	2			(1		)
Earnings before income taxes	$	128		$	20

(*) Net investment income (as a % of investments) of 4.63% and 4.64% for the three months ended December 31, 2019 and 2018, respectively, multiplied by the difference between average fixed annuity investments (at amortized cost) and average fixed annuity benefits accumulated in each period.

Holding Company, Other and Unallocated — Results of Operations

AFG’s net GAAP pretax loss outside of its property and casualty insurance and annuity segments (excluding realized gains and losses) totaled $55 million for the fourth quarter of 2019 compared to $29 million for the fourth quarter of 2018, an increase of $26 million (90%). AFG’s net core pretax loss outside of its property and casualty insurance and annuity segments (excluding realized gains and losses) totaled $50 million for the fourth quarter of 2019 compared to $29 million for the fourth quarter of 2018, an increase of $21 million (72%).

The following table details AFG’s GAAP and core loss before income taxes from operations outside of its property and casualty insurance and annuity segments for the three months ended December 31, 2019 and 2018 (dollars in millions):

Holding Company and Other — Life, Accident and Health Premiums, Benefits and Acquisition Expenses

AFG’s run-off long-term care and life insurance operations recorded net earned premiums of $5 million and related benefits and acquisition expenses of $11 million in the fourth quarter of 2019 compared to net earned premiums of $6 million and related benefits and acquisition expenses of $10 million in the fourth quarter of 2018. The $2 million (25%) increase in life, accident and health benefits reflects higher claims in the run-off life insurance business.

Holding Company and Other — Net Investment Income

AFG recorded net investment income on investments held outside of its property and casualty insurance and annuity segments of $8 million in the fourth quarter of 2019 compared to $4 million in the fourth quarter of 2018, an increase of $4 million (100%). The parent company holds a small portfolio of securities that are carried at fair value through net investment income. These securities increased in value by $1 million in the fourth quarter of 2019 compared to a decrease of $5 million in the fourth quarter of 2018.

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 fourth quarter of 2019, AFG collected $17 million in fees for these services compared to $19 million in the fourth quarter of 2018. Management views this fee income, net of the $13 million in both the fourth quarter of 2019 and the fourth quarter of 2018, in expenses incurred to generate such fees, as a reduction in the cost of underwriting its property and casualty insurance policies. 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 fourth quarter of 2019 and 2018, 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 $4 million in other income outside of its property and casualty insurance and annuity segments in the fourth quarter of 2019 compared to $5 million in the fourth quarter of 2018.

Holding Company and Other — Other Expenses

Excluding the non-core loss on retirement of debt discussed below, AFG’s holding companies and other operations outside of its property and casualty insurance and annuity segments recorded other expenses of $42 million in the fourth quarter of 2019 compared to $22 million in the fourth quarter of 2018, an increase of $20 million (91%). This increase is due primarily to the impact of higher holding company expenses related to employee benefit plans that are tied to stock market performance in the fourth quarter of 2019 compared to the fourth quarter of 2018.

79

Holding Company and Other — Interest Charges on Borrowed Money

AFG’s holding companies and other operations outside of its property and casualty insurance and annuity segments recorded interest expense of $18 million in the fourth quarter of 2019 compared to $16 million in the fourth quarter of 2018, an increase of $2 million (13%). The following table details the principal amount of AFG’s long-term debt balances as of December 31, 2019 compared to December 31, 2018 (dollars in millions):

	December 31, 2019			December 31, 2018

The increase in interest expense for the fourth quarter of 2019 as compared to the fourth quarter of 2018 reflects the following financing transactions completed by AFG between October 1, 2018 and December 31, 2019:

• Issued $125 million of 5.875% Subordinated Debentures in March 2019

• Issued $200 million of 5.125% Subordinated Debentures in December 2019

• Redeemed $150 million of 6-1/4% Subordinated Debentures in December 2019

Holding Company and Other — Loss on Retirement of Debt

In December 2019, AFG redeemed its $150 million outstanding principal amount of 6-1/4% Subordinated Debentures due 2054 and wrote off unamortized debt issuance costs of $5 million.

Consolidated Realized Gains (Losses) on Securities  

AFG’s consolidated realized gains (losses) on securities, which are not allocated to segments, were net gains of $65 million in the fourth quarter of 2019 compared to net losses of $238 million in the fourth quarter of 2018, a change of $303 million (127%). Realized gains (losses) on securities consisted of the following (in millions):

AFG’s impairment charges for the fourth quarter of 2019 consist of $7 million on corporate bonds and $2 million on third-party collateralized loan obligations compared to $17 million on corporate bonds and $6 million on residential MBS in the fourth quarter of 2018.

Consolidated Income Taxes   

AFG’s consolidated provision (credit) for income taxes was an expense of $68 million for the fourth quarter of 2019 compared to a credit of $4 million in the fourth quarter of 2018. The following is a reconciliation of income taxes at the statutory rate to the provision (credit) for income taxes as shown in the segmented statement of earnings (dollars in millions):

Consolidated Noncontrolling Interests   

AFG’s consolidated net earnings (losses) attributable to noncontrolling interests was a net loss of $20 million for the fourth quarter of 2019 compared to $6 million for the fourth quarter of 2018, an increase of $14 million (233%). The losses in both periods are related to losses at Neon, AFG’s United Kingdom-based Lloyd’s insurer. Net losses attributable to noncontrolling interests in the fourth quarter of 2019 includes $18 million related to the $76 million non-core charge for costs associated with AFG’s plans to exit the Lloyd’s of London insurance market in 2020. See “Neon exited lines charge” under “Property and Casualty Insurance Segment — Results of Operations” for the quarters ended December 31, 2019 and 2018.

RESULTS OF OPERATIONS — YEARS ENDED DECEMBER 31, 2019, 2018 AND 2017

Segmented Statement of Earnings   

AFG reports its business as three segments: (i) Property and casualty insurance (“P&C”), (ii) Annuity and (iii) Other, which includes run-off long-term care and life, holding company costs and income and expenses related to the managed investment entities (“MIEs”).

Effective January 1, 2018, the results of AFG’s run-off long-term care and life businesses are included in the “Other” segment instead of as a separate reportable segment based on the immaterial size of the remaining operations. Prior periods amounts were reclassified for consistent presentation.

AFG’s net earnings attributable to shareholders, determined in accordance with GAAP, include certain items that may not be indicative of its ongoing core operations. The following tables for the years ended December 31, 2019, 2018 and 2017 identify such items by segment and reconcile net earnings attributable to shareholders 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):

(b) As discussed under “Results of Operations — General,” beginning prospectively with the second quarter of 2019,

unlocking, the impact of changes in the fair value of derivatives related to FIAs, and other impacts of changes in the stock market and interest rates on the accounting for FIAs over or under the cost of the equity index options purchased to mitigate the risk in the index-based component of those FIAs are considered non-core earnings (losses).

Property and Casualty Insurance Segment — Results of Operations   

AFG’s property and casualty insurance operations contributed $649 million in GAAP pretax earnings in 2019 compared to $709 million in 2018, a decrease of $60 million (8%). Property and casualty core pretax earnings were $743 million in 2019 compared to $727 million in 2018, an increase of $16 million (2%). The decrease in GAAP pretax earnings reflects a pretax non-core charge of $76 million in 2019 related to costs associated with plans to exit the Lloyd’s of London insurance market in 2020, partially offset by higher core pretax earnings. The increase in core pretax earnings reflects

84

higher net investment income in 2019 compared to 2018 due primarily to growth in the business, partially offset by lower underwriting profit.

AFG’s property and casualty insurance operations contributed $709 million in GAAP pretax earnings in 2018 compared to $591 million in 2017, an increase of $118 million (20%). Property and casualty core pretax earnings were $727 million in 2018 compared to $662 million in 2017, an increase of $65 million (10%). The increase in GAAP and core pretax earnings reflects higher underwriting profit in 2018 compared to 2017 due primarily to higher favorable prior year reserve development and lower catastrophe losses, higher net investment income, due primarily to higher earnings from limited partnerships and similar investments and growth in the business, partially offset by the impact of income from the sale of real estate in 2017. The increase in GAAP pretax earnings also reflects lower special A&E charges in 2018 compared to 2017, partially offset by the impact of favorable reserve development of $18 million in the fourth quarter of 2017 in the Neon exited lines in connection with a reinsurance to close transaction.

The following table details AFG’s GAAP and core earnings before income taxes from its property and casualty insurance operations for the years ended December 31, 2019, 2018 and 2017 (dollars in millions):

Gross written premiums decreased $43 million (2%) in 2018 compared to 2017. This decrease was largely the result of lower year-over-year premiums in the crop insurance business and underwriting actions on under-performing accounts in the Singapore branch. Average renewal rates increased approximately 3% for this group in 2018. Reinsurance premiums ceded as a percentage of gross written premiums were comparable in 2018 and 2017.

Specialty casualty Gross written premiums increased $323 million (9%) in 2019 compared to 2018 due primarily to the addition of premiums from ABA Insurance Services and growth in the excess and surplus lines, executive liability and targeted markets businesses and higher premiums reported by Neon. This growth was partially offset by lower premiums in the workers’ compensation businesses. Average renewal rates increased approximately 3% for this group in 2019. Excluding rate decreases in the workers’ compensation business, renewal rates for this group increased approximately 8% in 2019. Reinsurance premiums ceded as a percentage of gross written premiums increased 1 percentage point in 2019 compared to 2018, reflecting growth in the surplus lines, excess liability and mergers and acquisitions businesses, which have a higher ceding percentage than many of the businesses in the Specialty casualty sub-segment.

Gross written premiums increased $358 million (12%) in 2018 compared to 2017 due primarily to growth at Neon.

The Specialty property and casualty insurance operations generated an underwriting profit of $325 million in 2019 compared to $322 million in 2018, an increase of $3 million (1%). The higher underwriting profit in 2019 reflects higher underwriting profits in the Specialty casualty and Specialty financial sub-segments, partially offset by lower underwriting profit in the Property and transportation sub-segment. Overall catastrophe losses were $60 million (1.2 points on the combined ratio) for 2019 compared to $103 million (2.1 points) for 2018. In connection with catastrophe losses incurred in 2019 and 2018, AFG paid $1 million and $2 million in net reinstatement premiums, respectively, resulting in total pretax losses from catastrophes of $61 million in 2019 and $105 million in 2018.

The Specialty property and casualty insurance operations generated an underwriting profit of $322 million in 2018 compared to $317 million in 2017, an increase of $5 million (2%). Higher underwriting profits in the Specialty casualty and Specialty financial sub-segments were partially offset by lower underwriting profit in the Property and transportation sub-segment. Overall catastrophe losses were $103 million (2.1 points on the combined ratio) for 2018 compared to $140 million (3.0 points) for 2017. In connection with catastrophe losses incurred in 2018, AFG paid $2 million in net reinstatement premiums, resulting in a total pretax loss from catastrophes of $105 million. In connection with catastrophe losses incurred in 2017, AFG reduced profit-based commissions payable to agents by $8 million in the Specialty financial sub-segment and paid $10 million in net reinstatement premiums, resulting in a total pretax loss from catastrophes of $142 million in 2017.

Property and transportation Underwriting profit for this group was $79 million in 2019 compared to $120 million in 2018, a decrease of $41 million (34%). Record levels of prevented planting claims in the crop operations were the driver of the lower underwriting profit in 2019 compared to 2018, partially offset by higher underwriting profits in the transportation businesses. Catastrophe losses were $32 million (1.8 points on the combined ratio) in 2019 compared to catastrophe losses of $26 million (1.5 points) in 2018.

88

Underwriting profit for this group was $120 million in 2018 compared to $154 million in 2017, a decrease of $34 million (22%). Lower underwriting profits in the agricultural, property and inland marine and aviation businesses and the Singapore branch were partially offset by higher underwriting profit at National Interstate and improved results in the ocean marine operations. Catastrophe losses were $26 million (1.5 points on the combined ratio) in 2018 compared to catastrophe losses of $36 million (2.1 points) and related net reinstatement premiums of $2 million in 2017.

Specialty casualty Underwriting profit for this group was $175 million in 2019 compared to $141 million in 2018, an increase of $34 million (24%). Higher underwriting profits in the targeted markets and workers’ compensation businesses and a reduction in the underwriting loss at Neon (excluding the Neon exited lines charge), due primarily to lower year-over-year catastrophe losses, were partially offset by lower underwriting profits in the excess and surplus lines, executive liability and general liability businesses. See “Neon exited lines charge” under “Property and Casualty Insurance Segment — Results of Operations” for the quarters ended December 31, 2019 and 2018 for information about AFG’s plans to exit the Lloyd’s of London insurance market in 2020. Catastrophe losses were $17 million (0.7 points on the combined ratio) and related net reinstatement premiums were $1 million in 2019 compared to catastrophe losses of $45 million (1.9 points) and related net reinstatement premiums of $1 million in 2018.

Underwriting profit for this group was $141 million in 2018 compared to $104 million in 2017, an increase of $37 million (36%). These results reflect higher underwriting profits in the executive liability and targeted markets businesses and lower adverse prior year reserve development in run-off businesses. Catastrophe losses were $45 million (1.9 points on the combined ratio) and related net reinstatement premiums were $1 million in 2018 compared to catastrophe losses of $71 million (3.3 points) and related net reinstatement premiums of $6 million in 2017.

Specialty financial Underwriting profit for this group was $92 million in 2019 compared to $66 million in 2018, an increase of $26 million (39%) due primarily to higher underwriting profitability in the financial institutions and surety businesses. Catastrophe losses were $10 million (1.6 points on the combined ratio) in 2019 compared to catastrophe losses of $28 million (4.7 points) and related net reinstatement premiums of $1 million in 2018.

Underwriting profit for this group was $66 million in 2018 compared to $61 million in 2017, an increase of $5 million (8%) due primarily to favorable prior year reserve development in run-off businesses. Catastrophe losses were $28 million (4.7 points on the combined ratio) in 2018 compared to $30 million (5.2 points) in 2017. In connection with catastrophe losses incurred in 2018, the Specialty financial sub-segment paid $1 million in reinstatement premiums compared to a reduction of profit-based commissions payable to agents of $8 million (1.1 points on the combined ratio) and reinstatement premiums of $2 million in 2017.

Other specialty This group reported an underwriting loss of $21 million in 2019 compared to $5 million in 2018, an increase of $16 million (320%). This increase reflects 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 2019 compared to 2018.

This group reported an underwriting loss of $5 million in 2018 compared to $2 million in 2017, an increase of $3 million (150%). The lower underwriting results are due primarily to losses in the business assumed by AFG’s internal reinsurance program from the operations that make up AFG’s other Specialty sub-segments in 2018, partially offset by the impact of a $14 million charge recorded in 2017 to adjust the deferred gain on the retroactive reinsurance transaction entered into in connection with the sale of businesses in 1998.

Aggregate Aggregate underwriting results for AFG’s property and casualty insurance segment include the asbestos and environmental reserve charges, the Neon exited lines charge and favorable development in the Neon exited lines. See “Neon exited lines charge” under “Property and Casualty Insurance Segment — Results of Operations” for the quarters ended December 31, 2019 and 2018. AFG also recorded adverse prior year reserve development of $19 million in 2019 related to business outside of the Specialty group that AFG no longer writes.

Net favorable reserve development of $21 million in 2017 reflects lower than anticipated claim severity in the fidelity business and lower than expected claim frequency and severity in the surety business.

Other specialty In addition to the reserve development discussed above, total Specialty prior year reserve development includes net adverse reserve development of $6 million, $3 million and $8 million in 2019, 2018, and 2017, respectively. The net adverse reserve development in 2019 reflects $12 million of adverse development associated with AFG’s internal reinsurance program, partially offset by the amortization of the deferred gains on the retroactive reinsurance transactions entered into in connection with the sale of businesses in 1998 and 2001.

The net adverse reserve development in 2018 reflects $10 million of adverse reserve development associated with AFG’s internal reinsurance program, partially offset by amortization of deferred gains on retroactive reinsurance.

The net adverse reserve development in 2017 reflects a $14 million charge to adjust the deferred gain on the retroactive reinsurance transaction entered into in connection with the sale of businesses in 1998, partially offset by the amortization of deferred gains on retroactive reinsurance and favorable reserve development associated with AFG’s internal reinsurance program.

Asbestos and environmental reserve charges   As previously discussed under “Uncertainties” — “Asbestos and Environmental-related (“A&E”) Insurance Reserves,” AFG has established property and casualty reserves for claims related to environmental exposures and asbestos claims. Total charges recorded to increase reserves (net of reinsurance recoverable) for A&E exposures of AFG’s property and casualty group (included in loss and loss adjustment expenses) were $18 million in both 2019 and 2018 and $89 million in 2017.

Neon exited lines reserve charge AFG recorded net adverse prior year reserve development of $7 million in 2019 and net favorable prior year reserve development of $18 million in 2017 related to Neon’s exited lines of business (included in loss and loss adjustment expenses). See “Neon exited lines charge” under “Property and Casualty Insurance Segment — Results of Operations” for the quarters ended December 31, 2019 and 2018 for information about AFG’s plans to exit the Lloyd’s of London insurance market in 2020.

Aggregate Aggregate net prior accident years reserve development for AFG’s property and casualty insurance segment includes the special A&E charges, reserve development related to the Neon exited lines mentioned above and net adverse reserve development of $19 million, $2 million and $4 million in 2019, 2018 and 2017, respectively, related to business outside the Specialty group that AFG no longer writes.

Catastrophe losses

AFG generally seeks to reduce its exposure to catastrophes through individual risk selection, including minimizing coastal and known fault-line exposures, and the purchase of reinsurance. AFG recorded net catastrophe losses of $60 million in 2019 primarily from winter storms in multiple regions of the United States in the first quarter, storms and tornadoes in multiple regions of the United States in the second quarter, Hurricane Dorian and Tropical Storm Imelda in the third quarter and Typhoons Faxai and Hagibis, storms and tornadoes in the south-central United States and the Kincade fire in California in the fourth quarter.

Catastrophe losses of $103 million in 2018 resulted primarily from mudslides in California in the first quarter, storms and flooding in several regions of the United States in the second quarter, Hurricane Florence in the third quarter and Hurricane Michael and wildfires in California in the fourth quarter.

Catastrophe losses of $140 million in 2017 resulted primarily from storms and tornadoes in several regions of the United States in the first and second quarters, Hurricanes Harvey, Irma and Maria, and earthquakes in Mexico in the third quarter and wildfires in California in the fourth quarter.

Commissions and Other Underwriting Expenses

AFG’s property and casualty commissions and other underwriting expenses (“U/W Exp”) were $1.70 billion in 2019 compared to $1.56 billion in 2018, an increase of $142 million (9%). AFG’s underwriting expense ratio was 32.8% in 2019 compared to 32.1% in 2018, an increase of 0.7 percentage points.

AFG’s property and casualty U/W Exp were $1.56 billion in 2018 compared to $1.38 billion in 2017, an increase of $178 million (13%). AFG’s underwriting expense ratio was 32.1% in 2018 compared to 30.2% in 2017, an increase of 1.9 percentage points.

Property and transportation   Commissions and other underwriting expenses as a percentage of net earned premiums increased 0.6 percentage points in 2019 compared to 2018 reflecting lower profitability-based ceding commissions received from reinsurers in the crop business.

Commissions and other underwriting expenses as a percentage of net earned premiums increased 1.6 percentage points in 2018 compared to 2017 reflecting lower premiums in the crop business, which has a lower expense ratio than many of the businesses in the Property and transportation sub-segment and an increase in the expense ratio in the transportation businesses.

Specialty casualty   Commissions and other underwriting expenses as a percentage of net earned premiums decreased 0.5 percentage points in 2019 compared to 2018 reflecting the impact of higher premiums on the ratio.

Commissions and other underwriting expenses as a percentage of net earned premiums increased 2.0 percentage points in 2018 compared to 2017 reflecting growth at Neon, which has a higher expense ratio than many of the businesses in the Specialty casualty sub-segment, higher dividends paid to policyholders in the workers’ compensation businesses and lower underwriting, policy administration and claims services fees collected from unaffiliated insurers in the workers’ compensation businesses.

Specialty financial   Commissions and other underwriting expenses as a percentage of net earned premiums increased 2.2 percentage points in 2019 compared to 2018 reflecting higher profitability-based commissions paid to agents in the financial institutions business, partially offset by lower underwriting expenses in the equipment leasing business.

Commissions and other underwriting expenses as a percentage of net earned premiums increased 1.3 percentage points in 2018 compared to 2017 reflecting higher profitability-based commissions paid to agents in the financial institutions business compared to 2017, which included an $8 million commission expense reduction due to hurricane losses in the 2017 period, partially offset by the impact of higher premiums on the ratio in the international operations.

Aggregate   Aggregate commissions and other underwriting expenses for AFG’s property and casualty insurance segment includes $30 million of underwriting expenses related to the Neon exited lines charge in 2019 representing contractual employee severance benefits and other incurred exit costs. See “Neon exited lines charge” under “Property and Casualty Insurance Segment — Results of Operations” for the quarters ended December 31, 2019 and 2018.

The increase in average invested assets and net investment income in the property and casualty insurance segment in 2019 compared to 2018 reflects growth in the property and casualty insurance segment. The property and casualty insurance segment’s overall yield on investments (net investment income as a percentage of average invested assets) was 4.16% in 2019 compared to 4.17% in 2018, a decrease of 0.01 percentage points, reflecting lower earnings from limited partnerships and similar investments. AFG’s property and casualty insurance operations recorded $74 million in earnings from partnerships and similar investments and AFG-managed CLOs in 2019 compared to $80 million in 2018, a decrease of $6 million (8%). The yield earned on these investments was 10.1% in 2019 compared to 13.9% in 2018.

The increase in average invested assets and net investment income in the property and casualty insurance segment in 2018 compared to 2017 reflects growth in the property and casualty insurance segment and very strong earnings from limited partnerships and similar investments. The property and casualty insurance segment’s overall yield on investments was 4.17% in 2018 compared to 3.64% in 2017, an increase of 0.53 percentage points due primarily to higher earnings from limited partnerships and similar investments. AFG’s property and casualty insurance operations recorded $80 million in earnings from partnerships and similar investments and AFG-managed CLOs in 2018 compared to $34 million in 2017, an increase of $46 million (135%). The yield earned on these investments was 13.9% in 2018 compared to 7.9% in 2017.

Property and Casualty Other Income and Expenses, Net

Annuity Segment — Results of Operations

AFG’s annuity operations contributed $362 million in GAAP pretax earnings in 2019 compared to $361 million in 2018, an increase of $1 million. This slight increase in AFG’s GAAP annuity segment results for 2019 compared 2018 is due primarily to the positive impact of strong market performance in the 2019 period, the unfavorable impact of the decline in the stock market in 2018 and higher unlocking charges in the 2018 period, offset by the unfavorable impact of significantly lower than anticipated interest rates on the fair value of derivatives related to FIAs in 2019 compared to the favorable impact of higher than anticipated interest rates in 2018. AFG monitors the major actuarial assumptions underlying its annuity operations throughout the year and conducts detailed reviews (“unlocking”) of its assumptions annually. Beginning with the third quarter of 2019, AFG moved its annual unlocking from the fourth quarter to the third quarter and expects to continue to conduct the annual review in the third quarter of each year (consistent with many of its peers). If changes in the economic environment or actual experience would cause material revisions to future estimates, these assumptions are updated (unlocked) in an interim quarter. In addition to the fourth quarter detailed review, AFG unlocked its assumptions for option costs and interest rates in the second quarter of 2018 due to continued higher FIA option costs (resulting primarily from higher than expected risk-free rates). AFG’s unlocking of the actuarial assumptions underlying its annuity operations resulted in a net charge of $1 million in 2019 compared to $31 million in 2018.

AFG’s annuity operations contributed $361 million in pretax earnings in 2018 compared to $380 million in 2017, a decrease of $19 million (5%). AFG’s annuity segment results in 2018 compared to 2017 reflect a 10% increase in average annuity investments (at amortized cost) and higher earnings from limited partnerships and similar investments, more than offset by higher unlocking charges, the impact of lower investment yields due to the run-off of higher yielding investments and the impact of higher than anticipated interest rates, higher than expected option costs and lower stock market performance in the 2018 period.

Annuity core earnings before income taxes were $398 million in 2019 compared to $361 million in 2018, an increase of $37 million (10%). As discussed under “Results of Operations — General,” beginning prospectively with the second quarter of 2019, unlocking, changes in the fair value of derivatives related to FIAs, and other impacts of changes in the stock market and interest rates on the accounting for FIAs over or under the cost of the equity index options purchased to mitigate the risk in the index-based component of those FIAs are considered non-core earnings (losses). For 2019, the annuity segment’s GAAP earnings before income taxes includes $47 million in pretax losses related to these items (including $11 million in the first quarter). Since annuity core earnings for the first quarter of 2019 and prior periods were not adjusted, the annuity segment’s core earnings before income taxes for 2019 includes the $11 million unfavorable impact from these items in the first quarter of 2019 and the full-year results for 2018 and 2017 include the $48 million and $8 million, respectively, unfavorable impact from these items. Excluding the unfavorable impact of these items in the first quarter of 2019 and full-year 2018, annuity core earnings before income taxes were $409 million for both 2019 and 2018 reflecting growth in the business, offset by the impact of lower investment yields and higher renewal option costs. Excluding the $48 million and $8 million unfavorable impact of these items in 2018 and 2017, respectively, annuity core earnings before income taxes for 2018 increased $21 million (5%) compared to 2017 reflecting growth in the business, partially offset by the impact of lower investment yields.

Because fluctuations in interest rates and the stock market, among other factors, can cause volatility in annuity benefits expense related to FIAs that can be inconsistent with the long-term economics of the FIA business, management believes that including the actual cost of the equity options purchased in the FIA business and excluding unlocking, the impact of changes in the fair value of derivatives related to FIAs, and other impacts of changes in the stock market and interest rates on the accounting for FIAs provides investors with a better view of the true cost of funds in the business and a more comparable measure to the cost of funds reported by its peers. The cost of the equity options included in AFG’s cost of funds is the net purchase price of the option contracts amortized on a straight-line basis over the life of the contracts, which is generally one year. The following table reconciles AFG’s non-GAAP cost of funds measure to total annuity benefits expense (in millions):

	Year ended December 31,

Total annuity benefits expense	$	1,151		$	998		$	892

As discussed under “Results of Operations — General,” beginning prospectively with the second quarter of 2019, unlocking, changes in the fair value of derivatives related to FIAs, and other impacts of changes in the stock market and interest rates on the accounting for FIAs over or under the cost of the equity index options purchased to mitigate the risk in the index-based component of those FIAs are considered non-core earnings (losses). For 2019, annuity benefits expense includes the negative impact of $56 million related to these items (including $45 million in the first quarter). Since annuity core earnings for the first quarter of 2019 and prior periods were not adjusted, core annuity benefits expense for

97

2019 includes the $45 million in expense from these items in the first quarter of 2019 and 2018 includes the $34 million unfavorable impact from these items. Excluding the $45 million expense in the first quarter of 2019, the $34 million unfavorable impact of these items in 2018 and the $57 million unfavorable impact of these items in 2017, core annuity benefits expense for 2019 increased $131 million compared to 2018 and increased $129 million in 2018 compared to 2017 reflecting growth in the annuity business and higher renewal option costs.

See “Annuity Unlocking” below for a discussion of the impact that the unlocking of actuarial assumptions had on annuity benefits expense.

Net investment income in 2019 was $1.79 billion compared to $1.64 billion in 2018, an increase of $154 million (9%). This increase reflects the growth in AFG’s annuity business, partially offset by the impact of lower investment yields. The overall yield earned on investments in AFG’s annuity operations, calculated as net investment income divided by average investment balances (at amortized cost), decreased by 0.06 percentage points to 4.67% from 4.73% in 2019 compared to 2018. The decrease in the net investment yield between periods reflects lower yields on investments accounted for under the equity method.

Net investment income in 2018 was $1.64 billion compared to $1.46 billion in 2017, an increase of $180 million (12%). This increase reflects growth in AFG’s annuity business and higher earnings from limited partnerships and similar investments, partially offset by the impact of lower investment yields. The overall yield earned on investments in AFG’s annuity operations increased by 0.10 percentage points to 4.73% from 4.63% in 2018 compared to 2017. This increase in net investment yield reflects higher earnings from limited partnerships and similar investments, partially offset by (i) the investment of new premium dollars at lower yields as compared to the existing investment portfolio and (ii) the impact of

98

the reinvestment of proceeds from maturity and redemption of higher yielding investments at the lower yields available in the financial markets. AFG’s annuity operations recorded $114 million in earnings from partnerships and similar investments and AFG-managed CLOs in 2018 compared to $53 million in 2017, an increase of $61 million (115%). The yield earned on these investments was 12.4% in 2018 compared to 8.2% in 2017.

Annuity Cost of Funds

Cost of funds for 2019 was $982 million compared to $863 million for 2018, an increase of $119 million (14%). This increase reflects growth in the annuity business and higher renewal option costs. The average cost of policyholder funds, calculated as cost of funds divided by average fixed annuity benefits accumulated, increased 0.06 percentage points to 2.55% from 2.49% in 2019 compared to 2018 reflecting higher renewal option costs.

Cost of funds for 2018 was $863 million compared to $739 million for 2017, an increase of $124 million (17%). This increase reflects growth in the annuity business and higher renewal option costs. The average cost of policyholder funds increased 0.15 percentage points to 2.49% from 2.34% in 2018 compared to 2017 reflecting higher renewal option costs.

The following table provides details of AFG’s interest credited and other cost of funds (in millions):

Other Annuity Benefits, Net of Guaranteed Withdrawal Benefit Fees

Other annuity benefits, net of guaranteed withdrawal benefit fees excluding the impact of unlocking and the stock market and interest rates for 2019 were $42 million in 2019 and $31 million in both 2018 and 2017, representing an increase of $11 million (35%) in 2019 compared to 2018. As a percentage of average fixed annuity benefits accumulated, these net expenses increased 0.01 percentage points to 0.11% in 2019 from 0.10% in both 2018 and 2017. In addition to interest credited to policyholders’ accounts and the change in fair value of derivatives related to fixed-indexed annuities, annuity benefits expense also includes the following expenses (in millions, net of guaranteed withdrawal benefit fees):

	Year ended December 31,
	2019			2018			2017
Other annuity benefits, excluding the impact of the stock market and interest rates on FIAs:
Amortization of sales inducements	$	13		$	19		$	18
Change in guaranteed withdrawal benefit reserve	84			74			68
Change in other benefit reserves	12			3			5
Other annuity benefits	109			96			91

Other annuity benefits — impact of the stock market and interest rates	14			83			58
Other annuity benefits, net	$	56		$	114		$	89

As discussed under “Annuity Benefits Accumulated” in Note A — “Accounting Policies” to the financial statements, guaranteed withdrawal benefit reserves are accrued for and modified using assumptions similar to those used in establishing and amortizing deferred policy acquisition costs. In addition, the guaranteed withdrawal benefit reserve related to FIAs can be inversely impacted by the calculated FIA embedded derivative reserve as the value to policyholders of the guaranteed withdrawal benefits decreases when the benefit of stock market participation increases. As shown in the table above, changes in the stock market and interest rates increased AFG’s guaranteed withdrawal benefit reserve by $14 million in 2019 compared to $83 million in 2018. This $69 million (83%) decrease was the primary cause of the $58 million overall decrease in other annuity benefits, net of guaranteed withdrawal fees in 2019 compared to 2018.

99

The change in the stock market and interest rates increased AFG’s guaranteed withdrawal benefit reserve by $83 million in 2018 compared to $58 million 2017. This $25 million (43%) increase was the primary cause of the $25 million overall increase in other annuity benefits, net of guaranteed withdrawal benefit fees in 2018 compared to 2017.

See “Annuity Unlocking” below for a discussion of the impact that the unlocking of actuarial assumptions had on annuity benefits expense.

Annuity Net Interest Spread

AFG’s net interest spread decreased 0.13 percentage points to 2.01% from 2.14% in 2019 compared to 2018 due primarily to higher renewal option costs and lower investment yields. Features included in current annuity product offerings allow AFG to achieve its desired profitability at a lower net interest spread than historical product offerings. As a result, AFG expects its net interest spread to narrow in the future.

AFG’s net interest spread decreased 0.05 percentage points to 2.14% in 2018 from 2.19% in 2017 due primarily to higher renewal option costs and lower investment yields, partially offset by higher earnings from limited partnerships and similar investments.

Annuity Policy Charges and Other Miscellaneous Income

Excluding the $1 million favorable impact of unlocking in 2019 and the $1 million unlocking charge in 2018 related to unearned revenue, annuity policy charges and other miscellaneous income, which consist primarily of surrender charges, amortization of deferred upfront policy charges (unearned revenue) and income from sales of real estate, were $40 million in 2019 compared to $43 million in 2018, a decrease of $3 million (7%). Excluding the impact of unlocking charges related to unearned revenue, annuity policy charges and other miscellaneous income as a percentage of average fixed annuity benefits accumulated decreased 0.02 percentage points to 0.08% in 2019 from 0.10% in 2018.

Excluding the impact of unlocking charges of $1 million in 2018 and $3 million in 2017 related to unearned revenue, annuity policy charges and other miscellaneous income were $43 million in 2018 compared to $46 million in 2017, a decrease of $3 million (7%). Other miscellaneous income includes $1 million from the sale of real estate in 2017. Excluding the impact of unlocking charges related to unearned revenue, annuity policy charges and other miscellaneous income as a percentage of average fixed annuity benefits accumulated decreased 0.01 percentage points to 0.10% in 2018 from 0.11% in 2017.

See “Annuity Unlocking” below for a discussion of the impact that the unlocking of actuarial assumptions had on annuity policy charges and other miscellaneous income.

Annuity Acquisition Expenses

In addition to the impact of unlocking, the following table illustrates the acceleration/deceleration of the amortization of

deferred policy acquisition costs (“DPAC”) resulting from changes in the fair value of derivatives related to FIAs and other

impacts of changes in the stock market and interest rates on the accounting for FIAs over or under option costs (in millions):

	Year ended December 31,
	2019			2018			2017
Annuity acquisition expenses before the impact of changes in the fair value of derivatives related to FIAs and other impacts of the stock market and interest rates	$	256		$	242		$	220
Unlocking	76			(29		)	(35		)
Impact of changes in the fair value of derivatives and other impacts of the stock market and interest rates:
Included in core	(34		)	42			(17		)
Annuity non-core earnings (losses)	(50		)	—			—
Annuity acquisition expenses	$	248		$	255		$	168

Annuity acquisitions expenses before unlocking and the acceleration/deceleration of the amortization resulting from changes in the fair value of derivatives related to FIAs and other impacts of changes in the stock market and interest rates on the accounting for FIAs over or under option costs were $256 million for 2019 compared to $242 million for 2018, an increase of $14 million (6%), reflecting growth in the annuity business.

Annuity acquisitions expenses before unlocking and the acceleration/deceleration of the amortization resulting from changes in the fair value of derivatives related to FIAs and other impacts of changes in the stock market and interest rates

100

on the accounting for FIAs over or under option costs were $242 million for 2018 compared to $220 million for 2017, an increase of $22 million (10%), reflecting growth in the annuity business.

See “Annuity Unlocking” below for a discussion of the impact that the unlocking of actuarial assumptions had on annuity and supplemental insurance acquisition expenses. Unanticipated spread compression, decreases in the stock market, adverse mortality experience, and higher than expected lapse rates could lead to future write-offs of DPAC or present value of future profits on business in force of companies acquired (“PVFP”).

The negative impact of lower than anticipated interest rates during 2019 on the fair value of derivatives and other liabilities related to FIAs resulted in a partially offsetting deceleration of the amortization of DPAC. In contrast, the positive impact of higher than anticipated interest rates during 2018 on the fair value of derivatives and other liabilities related to FIAs resulted in a partially offsetting acceleration of the amortization of DPAC. In 2017, the negative impact of significantly lower than anticipated interest rates on the fair value of derivatives and other liabilities related to FIAs resulted in a partially offsetting deceleration of the amortization of DPAC.

The table below illustrates the impact of unlocking and the estimated impact of changes in the fair value of derivatives related to fixed-indexed annuities and other impacts of changes in the stock market and interest rates on FIAs on annuity acquisition expenses as a percentage of average fixed annuity benefits accumulated:

	Year ended December 31,
	2019		2018		2017
Before unlocking, the impact of changes in the fair value of derivatives related to FIAs and other impacts of the stock market and interest rates	0.66	%	0.67	%	0.68	%
Unlocking	0.20	%	(0.08	%)	(0.11	%)
Impact of changes in fair value of derivatives and other impacts of the stock market and interest rates	(0.23	%)	0.12	%	(0.06	%)
Annuity acquisition expenses as a % of fixed annuity benefits accumulated	0.63	%	0.71	%	0.51	%

Annuity Other Expenses

Annuity other expenses were $139 million in 2019, $131 million in 2018 and $121 million in 2017, representing an increase of $8 million (6%) in 2019 compared to 2018 and an increase of $10 million (8%) in 2018 compared to 2017 reflecting growth in the annuity business. Annuity other expenses represent primarily general and administrative expenses, as well as selling and issuance expenses that are not deferred. As a percentage of average fixed annuity benefits accumulated, these expenses decreased 0.02 percentage points to 0.35% in 2019 from 0.37% in both 2018 and 2017.

Change in Fair Value of Derivatives Related to Fixed-Indexed (Including Variable-Indexed) Annuities and Other Impacts of Changes in the Stock Market and Interest Rates on FIAs

AFG’s fixed-indexed (including variable-indexed) annuities provide policyholders with a crediting rate tied, in part, to the performance of an existing stock market or other financial index. AFG attempts to mitigate the risk in the index-based component of these products through the purchase and sale of call and put options on the appropriate index. AFG’s strategy is designed so that the net change in the fair value of the call option assets and put option liabilities will generally offset the economic change in the net liability from the index participation. Both the index-based component of the annuities (an embedded derivative) and the related call and put options are considered derivatives that must be adjusted for changes in fair value through earnings each period. The fair values of these derivatives are impacted by actual and expected stock market performance and interest rates as well as other factors. For a list of other factors impacting the fair value of the embedded derivative component of AFG’s annuity benefits accumulated, see Note D — “Fair Value Measurements” to the financial statements. Fluctuations in certain of these factors, such as changes in interest rates and the performance of the stock market, are not economic in nature for the current reporting period, but rather impact the timing of reported results.

101

As discussed above under “Other Annuity Benefits, Net of Guaranteed Withdrawal Benefit Fees” and “Annuity Acquisition Expenses,” the periodic accounting for DPAC and guaranteed withdrawal benefits related to FIAs is also impacted by changes in the stock market and interest rates. These impacts may be temporary in nature and not necessarily indicative of the long-term performance of the FIA business. The table below highlights the impact of changes in the fair value of derivatives related to FIAs and the other impacts of the stock market and interest rates (excluding the impact of unlocking) over or under the cost of the equity index options (discussed above) on earnings before income taxes for the annuity segment (dollars in millions):

	Year ended December 31,									% Change
	2019			2018			2017			2019 - 2018		2018 - 2017
Change in the fair value of derivatives related to FIAs	$	(294	)	$	(51	)	$	(70	)	476	%	(27	%)
Accretion of guaranteed minimum FIA benefits	(408		)	(347		)	(289		)	18	%	20	%
Other annuity benefits	(14		)	(83		)	(58		)	(83	%)	43	%

Related impact on the amortization of DPAC	84			(42		)	17			(300	%)	(347	%)
Impact on annuity segment earnings before income taxes	$	(46	)	$	(17	)	$	(5	)	171	%	240	%

During 2019, the negative impact of significantly lower than anticipated interest rates, partially offset by the positive impact of strong stock market performance, reduced the annuity segments’ earnings before income taxes (excluding unlocking) by $46 million compared to the $17 million negative impact of the stock market and interest rates (excluding unlocking) on annuity earnings before income taxes for 2018, an increase of $29 million (171%). In 2018, the positive impact of higher than expected interest rates was more than offset by higher interest on the embedded derivative, the negative impact of higher than expected option costs and significantly lower stock market performance. In 2017, the negative impact of significantly lower than anticipated interest rates was partially offset by the positive impact of strong stock market performance. As a percentage of average fixed annuity benefits accumulated, the impact of changes in the fair value of derivatives related to FIAs and other impacts of changes in the stock market and interest rates on the accounting for FIAs over or under the cost of the equity index options purchased to mitigate the risk in the indexed-based component of those FIAs was a net expense of 0.12%, 0.04% and 0.01% in 2019, 2018 and 2017, respectively.

The following table provides analysis of the primary factors impacting the change in the fair value of derivatives related to FIAs and the other impacts of the stock market and interest rates (excluding the impact of unlocking) on the accounting for FIAs over or under the cost of the equity index options discussed above. Each factor is presented net of the estimated related impact on amortization of DPAC (dollars in millions).

	Year ended December 31,									% Change

See “Annuity Unlocking” below for a discussion of the impact that the unlocking of actuarial assumptions had on the change in the fair value of the embedded derivative and other annuity liabilities.

Annuity Net Spread Earned on Fixed Annuities

AFG’s net spread earned on fixed annuities excluding the impact of unlocking, changes in the fair value of derivatives related to FIAs and other impacts of changes in the stock market and interest rates over or under option costs decreased 0.12 percentage points to 1.08% in 2019 from 1.20% in 2018 due primarily to the 0.13 percentage points decrease in AFG’s net interest spread discussed above. AFG’s overall net spread earned on fixed annuities decreased 0.11 percentage points to 0.96% in 2019 from 1.07% in 2018 due to the decrease in AFG’s net interest spread, the impact of changes in the fair value of derivatives and other impacts of the stock market and interest rates on the accounting for FIAs discussed above partially offset by the impact of unlocking discussed below under “Annuity Unlocking.”

AFG’s net spread earned on fixed annuities excluding the impact of unlocking, changes in the fair value of derivatives related to FIAs and other impacts of changes in the stock market and interest rates over or under option costs decreased 0.05 percentage points to 1.20% in 2018 from 1.25% in 2017 due primarily to the 0.05 percentage point decrease in AFG’s net interest spread discussed above. AFG’s overall net spread earned on fixed annuities decreased 0.16 percentage points to 1.07% in 2018 from 1.23% in 2017 due to the decrease in AFG’s net interest spread, the impact

102

of changes in the fair value of derivatives and other impacts of the stock market and interest rates on the accounting for FIAs discussed above and the impact of the unlocking of actuarial assumptions discussed below under “Annuity Unlocking.”

Annuity Benefits Accumulated

Annuity premiums received and benefit payments are recorded as increases or decreases in annuity benefits accumulated rather than as revenue and expense. Increases in this liability for interest credited and other benefits are charged to expense and decreases for surrender and other policy charges are credited to other income.

For certain products, annuity benefits accumulated also includes reserves for accrued persistency and premium bonuses, excess benefits expected to be paid on future deaths and annuitizations (“EDAR”) and guaranteed withdrawal benefits. Annuity benefits accumulated also includes amounts advanced from the Federal Home Loan Bank of Cincinnati. The following table is a progression of AFG’s annuity benefits accumulated liability for 2019, 2018 and 2017 (in millions):

	Year ended December 31,
	2019			2018			2017
Beginning fixed annuity reserves	$	36,431		$	33,005		$	29,647
Fixed annuity premiums (receipts)	4,939			5,382			4,313
Federal Home Loan Bank advances and repayments	—			225			(64		)
Surrenders, benefits and other withdrawals	(3,260		)	(2,836		)	(2,246		)

Annuity benefits accumulated per balance sheet	$	40,406		$	36,616		$	33,316

Statutory Annuity Premiums

AFG’s annuity operations generated statutory premiums of $4.96 billion in 2019, $5.41 billion in 2018 and $4.34 billion in 2017, a decrease of $447 million (8%) in 2019 compared to 2018 and an increase of $1.07 billion (25%) in 2018 compared to 2017. The following table summarizes AFG’s annuity sales (dollars in millions):

	Year ended December 31,						% Change
	2019		2018		2017		2019 - 2018		2018 - 2017
Financial institutions single premium annuities — indexed	$	1,537	$	1,776	$	1,711	(13	%)	4	%
Financial institutions single premium annuities — fixed	1,229		492		622		150	%	(21	%)
Retail single premium annuities — indexed	943		1,418		990		(33	%)	43	%
Retail single premium annuities — fixed	120		87		70		38	%	24	%
Broker dealer single premium annuities — indexed	657		1,271		733		(48	%)	73	%
Broker dealer single premium annuities — fixed	32		14		7		129	%	100	%
Pension risk transfer	257		132		6		95	%	2,100	%
Education market — fixed and indexed annuities	164		192		174		(15	%)	10	%
Total fixed annuity premiums	4,939		5,382		4,313		(8	%)	25	%
Variable annuities	21		25		28		(16	%)	(11	%)
Total annuity premiums	$	4,960	$	5,407	$	4,341	(8	%)	25	%

Management attributes the 8% decrease in annuity premiums in 2019 compared to 2018 to the lower market interest rate environment. In response to the continued drop in market interest rates during 2019, AFG lowered crediting rates on several products, which has slowed annuity sales compared to 2018 levels.

103

Management attributes the 25% increase in annuity premiums in 2018 compared to 2017 to the introduction of new products, efforts to expand in the retail and broker dealer markets and an improving interest rate environment in 2018.

Annuity Unlocking

AFG monitors the major actuarial assumptions underlying its annuity operations throughout the year and conducts detailed reviews (“unlocking”) of its assumptions annually. Beginning with the third quarter of 2019, AFG moved its unlocking from the fourth quarter to the third quarter and expects to continue to conduct the annual review in the third quarter of each year (consistent with many of its peers). If changes in the economic environment or actual experience would cause material revisions to future estimates, these assumptions are updated (unlocked) in an interim period.

The unlocking of the major actuarial assumptions underlying AFG’s annuity operations resulted in net charges related to its annuity business of $1 million, $31 million and $3 million in 2019, 2018 and 2017, respectively, which impacted AFG’s financial statements as follows (in millions):

	Year ended December 31,
	2019			2018			2017
Policy charges and other miscellaneous income:
Unearned revenue	$	1		$	(1	)	$	(3	)

Total costs and expenses	2			30			—
Net charge	$	(1	)	$	(31	)	$	(3	)

See “Annuity Unlocking” under “Annuity Segment — Results of Operations” for the quarters ended December 31, 2019 and 2018 for a discussion of the overall net expense reduction from the periodic review of actuarial assumptions in the fourth quarter of 2018.

The net charge from unlocking annuity assumptions in 2019 is due primarily to the unfavorable impacts of a decrease in projected net interest spreads on in-force business (due primarily to lower than previously anticipated reinvestment rates and the impact of lower than previously anticipated interest rates on floating rate investments) and higher assumed persistency in certain blocks of business, offset by lowering projected FIA option costs, including anticipated renewal rate actions. For the 2019 unlocking, reinvestment rate assumptions are based primarily on the expectation that the 7-year U.S. Treasury rate will increase to 3.20% and the 10-year U.S. Treasury rate will increase to 3.50% over time. For the unlocking in the third quarter of 2019, AFG assumed a net reinvestment rate (net of default and expense assumptions) of 3.38% for the fourth quarter of 2019, grading up ratably to an ultimate net reinvestment rate of 5.34% in 2029 and beyond.

In addition to the $4 million net charge from the periodic review of annuity assumptions in the fourth quarter of 2018, AFG recorded a $27 million net unlocking charge in the second quarter of 2018 due primarily to the unfavorable impact of higher projected option costs, partially offset by the favorable impact of an increase in projected net interest spreads on in-force business (due primarily to higher than previously anticipated reinvestment rates).

The 2017 net charge reflects the unfavorable impacts of a decrease in projected net interest spreads on in-force business (due primarily to lower than previously anticipated reinvestment rates), a slight increase in projected expenses (due primarily to an increase in projected trailer commissions) and slightly higher projected option costs in the near term, substantially offset by the favorable impact of changes in projected policyholder annuitization and lapse behavior.

Holding Company, Other and Unallocated — Results of Operations   

AFG’s net GAAP pretax loss outside of its property and casualty insurance and annuity segments (excluding realized gains and losses) totaled $190 million in 2019 compared to $165 million in 2018, an increase of $25 million (15%). AFG’s net core pretax loss outside of its property and casualty insurance and annuity segments (excluding realized gains and losses) totaled $174 million in 2019 compared to $156 million in 2018, an increase of $18 million (12%).

AFG’s net GAAP pretax loss outside of its property and casualty insurance and annuity segments (excluding realized gains and losses) totaled $165 million in 2018 compared to $252 million in 2017, a decrease of $87 million (35%). AFG’s net core pretax loss outside of its property and casualty insurance and annuity segments (excluding realized gains and losses) totaled $156 million in 2018 compared to $177 million in 2017, a decrease of $21 million (12%).

The following table details AFG’s GAAP and core loss before income taxes from operations outside of its property and casualty insurance and annuity segments in 2019, 2018 and 2017 (dollars in millions):

Holding Company and Other — Life, Accident and Health Premiums, Benefits and Acquisition Expenses

AFG’s run-off long-term care and life insurance operations recorded net earned premiums of $22 million and related benefits and acquisition expenses of $41 million in 2019 compared to net earned premiums of $24 million and related benefits and acquisition expenses of $46 million in 2018. The $4 million (10%) decrease in life, accident and health benefits reflects lower claims in both the run-off life and run-off long-term care insurance businesses in 2019 compared to 2018.

AFG’s run-off long-term care and life insurance operations recorded net earned premiums of $24 million and related benefits and acquisition expenses of $46 million in 2018 compared to net earned premiums of $22 million and related benefits and acquisition expenses of $31 million in 2017. The $14 million (54%) increase in life, accident and health benefits reflects higher claims in both the run-off life and run-off long-term care insurance businesses in 2018 compared to 2017.

106

Holding Company and Other — Net Investment Income

AFG recorded net investment income on investments held outside of its property and casualty insurance and annuity segments of $43 million, $25 million and $34 million in 2019, 2018 and 2017, respectively. The $18 million (72%) increase in 2019 compared to 2018 and the $9 million (26%) decrease in 2018 compared to 2017 is due primarily to the impact of the market performance on a small portfolio of securities that are carried at fair value through net investment income. These securities increased in value by $13 million in 2019, decreased in value by $4 million in 2018 and increased in value by $6 million in 2017.

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 both 2019 and 2018, AFG collected $69 million in fees for these services compared to $66 million in 2017. Management views this fee income, net of the $46 million in both 2019 and 2018 and $41 million in 2017, in expenses incurred to generate such fees, as a reduction in the cost of underwriting its property and casualty insurance policies. 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 $15 million, $16 million and $18 million in 2019, 2018 and 2017, respectively, 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 Consolidated 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 and annuity segments of $13 million in both 2019 and 2018 and $9 million in 2017.

Holding Company and Other — Other Expenses

Excluding the non-core special A&E charges and the non-core loss on retirement of debt discussed below, AFG’s holding companies and other operations outside of its property and casualty insurance and annuity segments recorded other expenses of $158 million in 2019 compared to $126 million in 2018, an increase of $32 million (25%). This increase reflects a $3 million charitable donation in 2019 and higher holding company expenses related to employee benefit plans that are tied to stock market performance in 2019 compared to 2018, partially offset by a $5 million charge to increase liabilities related to the environmental exposures of AFG’s former railroad and manufacturing operations in 2018.

AFG’s holding companies and other operations outside of its property and casualty insurance and annuity segments recorded other expenses of $126 million in 2018 compared to $144 million in 2017, a decrease of $18 million (13%). This decrease reflects lower holding company expenses related to employee benefits plans that are tied to stock market performance, partially offset by a $5 million charge to increase liabilities related to the environmental exposures of AFG’s former railroad and manufacturing operations in 2018.

Holding Company and Other — Interest Charges on Borrowed Money

The following table details the principal amount of AFG’s long-term debt balances as of December 31, 2019, December 31, 2018 and January 1, 2017 (dollars in millions):

	December 31, 2019			December 31, 2018			January 1, 2017

107

AFG’s holding companies and other operations outside of its property and casualty insurance and annuity segments recorded interest expense of $68 million in 2019, $62 million in 2018 and $85 million in 2017. The $6 million (10%) increase in interest expense in 2019 compared to 2018 primarily reflects the issuance of $125 million of 5.875% Subordinated Debentures in March 2019. The $23 million (27%) decrease in interest expense in 2018 compared to 2017 reflects a lower weighted average interest rate on AFG’s outstanding debt.

The increase in interest expense in 2019 compared to 2018 and the decrease in interest expense in 2018 compared to 2017 reflect the following financing transactions completed by AFG between January 1, 2017 and December 31, 2019:

• Issued $350 million of 4.50% Senior Notes in June 2017

• Redeemed $230 million of 6-3/8% Senior Notes in June 2017

• Redeemed $125 million of 5-3/4% Senior Notes in August 2017

• Issued an additional $125 million of 3.50% Senior Notes in November 2017

• Issued an additional $240 million of 4.50% Senior Notes in November 2017

• Redeemed $350 million of 9-7/8% Senior Notes in December 2017

• Issued $125 million of 5.875% Subordinated Debentures in March 2019

• Issued $200 million of 5.125% Subordinated Debentures in December 2019

• Redeemed $150 million of 6-1/4% Subordinated Debentures in December 2019

Holding Company and Other — Special A&E Charges

As a result of the comprehensive external studies and internal reviews of A&E exposures discussed under “Uncertainties — Asbestos and Environmental-related (“A&E”) Insurance Reserves,” AFG’s holding companies and other operations outside of its property and casualty insurance and annuity segments recorded non-core special charges of $11 million in 2019, $9 million in 2018 and $24 million in 2017 to increase liabilities related to the A&E exposures of AFG’s former railroad and manufacturing operations. The charges in 2019, 2018 and 2017 are due to relatively small movements across several sites that primarily reflect changes in the scope and costs of investigation. AFG has also increased its reserve for asbestos and toxic substance exposures arising out of these operations. Total charges recorded to increase liabilities for A&E exposures of AFG’s former railroad and manufacturing operations (included in other expenses) were $19 million in 2019, $21 million in 2018 and $31 million in 2017.

Holding Company and Other — Loss on Retirement of Debt

In December 2019, AFG redeemed its $150 million outstanding principal amount of 6-1/4% Subordinated Debentures due 2054 at par value and wrote off unamortized debt issuance costs of $5 million.

In December 2017, AFG redeemed its $350 million outstanding principal amount of 9-7/8% Senior Notes due 2019 and recorded a pretax loss on retirement of debt of $40 million, primarily a $38 million make-whole premium. In addition, AFG wrote off unamortized debt issuance costs of $7 million related to the redemption of its $230 million outstanding 6-3/8% Senior Notes due 2042 at par value in June 2017 and $4 million related to the redemption of its $125 million outstanding 5-3/4% Senior Notes due 2042 at par value in August 2017.

Consolidated Realized Gains (Losses) on Securities

AFG’s consolidated realized gains (losses) on securities, which are not allocated to segments, were net gains of $287 million in 2019 compared to net losses of $266 million in 2018, a change of $553 million (208%). AFG’s consolidated realized gains (losses) on securities were net losses of $266 million in 2018 compared to net gains of $5 million in 2017, a change of $271 million (5,420%). Realized gains (losses) on securities consisted of the following (in millions):

(*) As discussed in Note A — “Accounting Policies — Investments,” beginning in January 2018, all equity securities other than those accounted for under the equity method are carried at fair value through net earnings. These

108

amounts include a $169 million net gain and a $279 million net loss on securities that were still held at December 31, 2019 and 2018, respectively.

The $278 million net realized gain from the change in the fair value of equity securities in 2019 includes gains of $97 million on investments in banks and financing companies, $36 million from investments in media companies, $32 million from investments in technology companies, $21 million on investments in asset management companies and $21 million on insurance companies. AFG’s impairment charges in 2019 include $17 million in charges on third-party collateralized loan obligations and $11 million on corporate bonds.

The $262 million net realized loss from the change in the fair value of equity securities in 2018 includes losses of $92 million on banks and financing companies, $31 million on real estate investment trusts, $30 million on energy exploration and production companies and $27 million on asset management companies. AFG’s impairment charges on securities in 2018 all relate to fixed maturities. Approximately $19 million of impairment charges were taken on corporate bonds and $6 million were taken on residential MBS.

AFG’s impairment charges on securities in 2017 consist of $63 million on equity securities, $21 million on fixed maturities and $4 million on other investments. Approximately $28 million of the impairment charges in 2017 relates to investments in pharmaceutical companies, $24 million relates to investments in various industrial entities, $14 million relates to investments in financial institutions and $12 million relates to investments in media companies.

Consolidated Income Taxes   

AFG’s consolidated provision for income taxes was $239 million in 2019 compared to $122 million in 2018, an increase of $117 million (96%). AFG’s consolidated provision for income taxes was $122 million in 2018 compared to $247 million in 2017, a decrease of $125 million (51%). See Note M — “Income Taxes” to the financial statements for an analysis of items affecting AFG’s effective tax rate.

Consolidated Noncontrolling Interests   

AFG’s consolidated net earnings (losses) attributable to noncontrolling interests was a net loss of $28 million in 2019 compared to $13 million in 2018, an increase of $15 million (115%). AFG’s consolidated net earnings (losses) attributable to noncontrolling interests was a net loss of $13 million in 2018 compared to net earnings of $2 million in 2017, a change of $15 million (750%). The following table details net earnings (losses) in consolidated subsidiaries attributable to holders other than AFG (dollars in millions):

	Year ended December 31,								% Change
	2019			2018			2017		2019 - 2018		2018 - 2017
Neon	$	(28	)	$	(13	)	$	—	115	%	—	%
Other	—			—			2		—	%	(100	%)
Earnings (losses) attributable to noncontrolling interests	$	(28	)	$	(13	)	$	2	115	%	(750	%)

Net losses attributable to noncontrolling interests in 2019 includes $18 million related to the $76 million non-core charge for costs associated with AFG’s plans to exit the Lloyd’s of London insurance market in 2020. See “Neon exited lines charge” under “Property and Casualty Insurance Segment — Results of Operations” for the quarters ended December 31, 2019 and 2018.

Other noncontrolling interests includes $2 million related to the gain on the sale of a hotel property in the first quarter of 2017. The property was owned by an 80%-owned subsidiary of GAI.

RECENTLY ADOPTED ACCOUNTING STANDARDS

See Note A — “Accounting Policies — Leases” and Note K — “Leases” to the financial statements for a discussion of accounting guidance adopted on January 1, 2019, which requires entities that lease assets for terms longer than one year to recognize the assets and liabilities for the rights and obligations created by those leases on the balance sheet based on the present value of cash flows.

See Note A — “Accounting Policies — Investments” to the financial statements for a discussion of accounting guidance adopted on January 1, 2018, which, among other things, requires equity investments that are not accounted for under the equity method of accounting to be measured at fair value with changes in fair value recognized in net earnings.

109

See Note A — “Accounting Policies — Income Taxes” to the financial statements for a discussion of accounting guidance adopted effective December 31, 2017, which allows the reclassification of amounts stranded in accumulated other comprehensive income from accounting for the Tax Cuts and Jobs Act of 2017 to retained earnings.

ACCOUNTING STANDARDS TO BE ADOPTED

See Note A — “Accounting Policies — Credit Impairment Guidance Effective in 2020” to the financial statements for a discussion of accounting guidance adopted on January 1, 2020, which provides a new credit loss model for determining credit-related impairments for financial instruments measured at amortized cost (mortgage loans, premiums receivable and reinsurance recoverables) and requires an entity to estimate the credit losses expected over the life of an exposure or pool of exposures. The new guidance is not expected to have a material impact on AFG’s results of operations or financial position.

In August 2018, the FASB issued ASU 2018-12, Financial Services – Insurance: Targeted Improvements to the Accounting for Long-Duration Contracts, which changes the assumptions used to measure the liability for future policy benefits for traditional and limited pay contracts (e.g. life, accident and health benefits) from being locked in at inception to being updated at least annually and standardizes the liability discount rate to be used and updated each reporting period, requires the measurement of market risk benefits associated with deposit contracts (e.g. annuities) to be recorded at fair value, simplifies the amortization of deferred policy acquisition costs to a constant level basis over the expected life of the related contracts and requires enhanced disclosures. AFG will be required to adopt this guidance effective January 1, 2022. AFG cannot estimate the impact that the updated guidance will have on its results of operations, financial position or liquidity until the updated guidance is closer to adoption.

110

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

Market risk represents the potential economic loss arising from adverse changes in the fair value of financial instruments. AFG’s exposures to market risk relate primarily to its investment portfolio and annuity contracts, which are exposed to interest rate risk and, to a lesser extent, equity price risk. To a much lesser extent, AFG’s long-term debt is also exposed to interest rate risk.

Fixed Maturity Portfolio   In general, the fair value of AFG’s fixed maturity investments is inversely correlated to changes in interest rates. AFG’s fixed maturity portfolio is comprised of primarily fixed-rate investments with intermediate-term maturities. This practice is designed to allow flexibility in reacting to fluctuations of interest rates. The portfolios of AFG’s insurance operations are managed with an attempt to achieve an adequate risk-adjusted return while maintaining sufficient liquidity to meet policyholder obligations. AFG’s annuity and run-off long-term care and life operations attempt to align the duration of their invested assets to the projected cash flows of policyholder liabilities.

Consistent with the discussion in Item 7 — 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 and accumulated other comprehensive income that an immediate increase of 100 basis points in the interest rate yield curve would have at December 31 (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. 

	2019			2018
Fair value of fixed maturity portfolio	$	46,618		$	42,102
Percentage impact on fair value of 100 bps increase in interest rates	(4.0		%)	(4.5		%)
Pretax impact on fair value of fixed maturity portfolio	$	(1,865	)	$	(1,895	)
Offsetting adjustments to deferred policy acquisition costs and other balance sheet amounts	850			800
Estimated pretax impact on accumulated other comprehensive income	(1,015		)	(1,095		)
Deferred income tax	213			230
Estimated after-tax impact on accumulated other comprehensive income	$	(802	)	$	(865	)

Municipal bonds represented approximately 15% of AFG’s fixed maturity portfolio at December 31, 2019. AFG’s municipal bond portfolio is high quality, with 99% of the securities rated investment-grade at that date. The portfolio is well diversified across the states of issuance and individual issuers. At December 31, 2019, approximately 79% of the municipal bond portfolio was held in revenue bonds, with the remaining 21% held in general obligation bonds.

Annuity Contracts   Substantially all of AFG’s fixed rate annuity contracts permit AFG to change crediting rates (subject to minimum interest rate guarantees as determined by applicable law) enabling management to react to changes in market interest rates. At December 31, 2019, AFG could reduce the average crediting rate on approximately $30 billion of traditional fixed, fixed-indexed and variable-indexed annuities without guaranteed withdrawal benefits by approximately 119 basis points (on a weighted average basis).

As presented in Item 7 — Management’s Discussion and Analysis — “Results of Operations — Annuity Segment — Years ended December 31, 2019, 2018 and 2017 — Net Spread on Fixed Annuities,” the cost of funds as a percent of fixed annuity benefits accumulated on AFG’s in-force block of fixed annuities was 2.55% for the year ended December 31, 2019. Management estimates that the cost of funds rate on this in-force business will range from 2.40% to 2.55% over the next three years. This rate reflects actuarial assumptions as to (i) expected investment spreads, (ii) deaths, (iii) annuitizations, (iv) surrenders and other withdrawals, (v) renewal premiums, and (vi) stock market performance and the cost of equity options. Actual experience and changes in actuarial assumptions may result in different effective cost of funds rates than those above.

Actuarial assumptions used to estimate DPAC and certain annuity liabilities, as well as AFG’s ability to maintain spread, could be impacted if a low interest rate environment continues for an extended period, or if increases in interest rates cause policyholder behavior to differ significantly from current expectations.

111

Projected payments (in millions) in each of the subsequent five years and for all years thereafter on AFG’s fixed annuity liabilities at December 31 were as follows:

	First		Second		Third		Fourth		Fifth		Thereafter		Total		Fair Value (*)
2019	$	3,546	$	4,185	$	4,634	$	5,196	$	5,839	$	22,051	$	45,451	$	40,182
2018	3,493		3,989		4,609		4,701		4,640		22,156		43,588		34,765

(*) Fair value of annuity benefits accumulated excluding life contingent annuities in the payout phase (carrying value of $247 million at December 31, 2019 and $232 million at December 31, 2018).

AFG’s fixed-indexed (including variable-indexed) annuities provide policyholders with a crediting rate tied, in part, to the performance of an existing stock market or other financial index. AFG attempts to mitigate the risk in the index-based component of these products through the purchase and sale of call and put options on the appropriate index. AFG’s strategy is designed so that the net change in the fair value of the call option assets and put option liabilities will generally offset the economic change in the net liability from the index participation. Both the index-based component of the annuities (an embedded derivative) and the related call and put options are considered derivatives that must be adjusted for changes in fair value through earnings each period. See Note D — “Fair Value Measurements” and Note F — “Derivatives” to the financial statements for a discussion of these derivatives.

Long-Term Debt   The following table shows scheduled principal payments on fixed-rate long-term debt of AFG and its subsidiaries and related weighted average interest rates for each of the subsequent five years and for all years thereafter (dollars in millions):

Item 9A. 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 fourth fiscal quarter of 2019 that materially affected, or are reasonably likely to materially affect, AFG’s internal control over financial reporting.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

AFG’s management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Securities Exchange Act Rules 13a-15(f). Under the supervision and with the participation of management, including AFG’s Co-Chief Executive Officers and Chief Financial Officer, AFG conducted an evaluation of the effectiveness of internal control over financial reporting as of December 31, 2019, based on the criteria set forth in “Internal Control — Integrated Framework” issued in 2013 by the Committee of Sponsoring Organizations of the Treadway Commission.

There are inherent limitations to the effectiveness of any system of internal controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective internal controls and procedures can only provide reasonable assurance of achieving their control objectives.

Based on AFG’s evaluation, management concluded that internal control over financial reporting was effective as of December 31, 2019. The attestation report of AFG’s independent registered public accounting firm on AFG’s internal control over financial reporting as of December 31, 2019, is set forth on the next page.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

ON INTERNAL CONTROL OVER FINANCIAL REPORTING

To the shareholders and Board of Directors of American Financial Group, Inc. and subsidiaries

Opinion on Internal Control Over Financial Reporting

We have audited American Financial Group, Inc. and subsidiaries’ internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the “COSO criteria”). In our opinion, American Financial Group, Inc. and subsidiaries (the “Company”) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the consolidated balance sheets of the Company as of December 31, 2019 and 2018, the related consolidated statements of earnings, comprehensive income, changes in equity and cash flows for each of the three years in the period ended December 31, 2019, and the related notes and financial statement schedules listed in the Index at Item 15(a)(2) and our report dated February 25, 2020 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

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

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

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and Board of Directors of American Financial Group, Inc. and subsidiaries

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of American Financial Group, Inc. and subsidiaries (the “Company”) as of December 31, 2019 and 2018, the related consolidated statements of earnings, comprehensive income, changes in equity and cash flows for each of the three years in the period ended December 31, 2019, and the related notes and financial statement schedules listed in the Index at Item 15(a)(2) (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2019, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company’s internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 25, 2020 expressed an unqualified opinion thereon.

Adoption of New Accounting Standard

As discussed in Note A to the consolidated financial statements, the Company changed its method of accounting for equity investments, other than those accounted for under the equity method, to measure equity investments at fair value with changes in fair value recognized in net earnings in 2018.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Valuation of investments in securities

Description of the Matter

As of December 31, 2019, the fair value of the Company’s fixed-income and equity securities totaled $48.56 billion, a portion of which are valued based on non-binding broker quotes or internally developed using significant inputs not based on, or corroborated by, observable market information. The fair value of these securities are determined by management applying the methodologies outlined in Note D to the consolidated financial statements. The lack of visibility into assumptions used in non-binding broker quotes and the credit spread applied by management for internally developed fixed-income investments are significant unobservable inputs, which create greater subjectivity when determining the fair values. Credit spread inputs are developed based on management’s review of trade activity for comparable securities and credit spreads over the treasury yield of securities with a similar duration. Auditing the fair value of the fixed-income and equity securities that use unobservable inputs was complex and highly judgmental due to the judgment used by the Company in determining unobservable inputs and assumptions to estimate the securities’ fair value. Significant unobservable inputs and assumptions include non-binding broker quotes and credit spreads over the treasury yield.

F-1

How We Addressed the Matter in Our Audit We obtained an understanding, evaluated the design, and tested the operating effectiveness of controls over management’s valuation process for the fixed-income and equity securities priced using unobservable inputs. This included, among others, testing controls over investment pricing and the development and review of significant inputs and assumptions used in determining the fair values.

To test the Company’s investment fair values, our audit procedures included, among others, comparing the fair values for a sample of securities to pricing service values or internally developed cash flow models. With the assistance of our valuation specialists, we evaluated the valuation methodologies used by the Company and compared the Company’s fair value estimate to an independently calculated range of fair value estimates for a sample of securities. We evaluated information that corroborated or contradicted the Company’s fair value estimates, including observable yields, transaction data for similar securities, and historical collateral performance data.

Property and casualty unpaid losses and loss adjustment expenses

Description of the Matter

As of December 31, 2019, the Company’s unpaid losses and loss adjustment expenses reserve liabilities net of reinsurance recoverables, net of allowance, (“reserves”) totaled $7.21 billion as disclosed in Note P to the consolidated financial statements. This liability represents management’s best estimate of the ultimate net cost of all unpaid losses and loss adjustment expenses and is determined by using case-basis evaluations, actuarial projections, and management’s judgment. Estimating the reserves is inherently judgmental and is influenced by factors that are subject to significant variation, particularly for lines of business that develop or are paid over a long period of time or that contain exposures with high potential severities, such as workers’ compensation, other liability, and asbestos and environmental.   Auditing management’s best estimate of reserves was complex because it required the involvement of our actuarial specialists due to the highly judgmental nature of the assumptions used in the evaluation process. The significant judgment was primarily due to the sensitivity of management’s best estimate to the selection and weighting of actuarial methods, loss development factors, expected loss ratios, and inflation. These assumptions have a significant effect on the valuation of reserves.

How We Addressed the Matter in Our Audit We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the process for estimating reserves. This included, among others, the review and approval processes that management has in place for the methods and assumptions used in estimating the reserves.

With the assistance of actuarial specialists, our audit procedures included, among others, an evaluation of the Company’s selection and weighting of actuarial methods used with those methods used in prior periods and those used in the industry for the specific types of insurance. To evaluate the significant assumptions used by management, we compared the significant assumptions, including loss development factors, expected loss ratios, and inflation, to factors historically used and current industry benchmarks. We also performed a review of the development of prior years’ reserve estimates. With the assistance of actuarial specialists, we established an independent range of reasonable reserve estimates, which we compared to management’s best estimate.

Amortization of annuity deferred policy acquisition costs

Description of the Matter

At December 31, 2019, deferred policy acquisition costs totaled $1.04 billion, of which $696 million related to annuity contracts. As described in Notes A and G to the consolidated financial statements, the carrying amount of the annuity deferred policy acquisition costs is the total of costs deferred less amortization that is calculated in relation to the present value of estimated gross profits of the underlying annuity policies. There is a significant amount of uncertainty inherent in calculating estimated gross profits as the calculation is sensitive to management’s best estimate of assumptions, such as future investment yields, lapse rates, mortality, and morbidity. Management’s assumptions are adjusted, also known as unlocking, over time for emerging experience and expected trends. The unlocking results in amortization being recalculated, using the new assumptions for estimated gross profits, that results either in additional or less cumulative amortization expense. Auditing management’s estimate of the amortization of annuity deferred policy acquisition costs was complex because it required the involvement of our actuarial specialists due to the highly judgmental nature of the assumptions used in management’s projection of estimated gross profits, which are used in the amortization of annuity deferred policy acquisition costs. The significant judgment was primarily due to the sensitivity of the estimated gross profits to the expected investment yield and lapse rate assumptions.

F-2

How We Addressed the Matter in Our Audit We obtained an understanding, evaluated the design, and tested the operating effectiveness of controls over the process for estimating amortization of annuity deferred policy acquisition costs. This included, among others, controls over the review and approval processes that management has in place for the assumptions used in measuring estimated gross profits.

To test the amortization of deferred policy acquisition costs related to annuity contracts, our audit procedures included, among others, testing the completeness and accuracy of the data used to calculate the estimated gross profits through testing the reconciliation of the underlying data recorded in the source systems to the actuarial valuation models. With the assistance of our actuarial specialists, we evaluated the assumptions used by management in determining estimated gross profits with those used in prior periods. Also, with the assistance of our actuarial specialists, we compared significant assumptions, including expected investment yields and lapse rates, to prior actual experience and observable market data, and we evaluated management’s estimates of prospective changes in these assumptions. In addition, we performed an independent calculation of estimated and actual gross profits for a sample of product cohorts for comparison with the actuarial model used by management.

Valuation of annuity contract embedded derivatives

Description of the Matter

At December 31, 2019, the liability for annuity benefits accumulated included $3.73 billion for the embedded derivatives related to the equity participation feature of the Company’s fixed-indexed annuity products. As described in Note F to the consolidated financial statements, there is a significant amount of estimation uncertainty inherent in measuring the fair value of the embedded derivatives as it includes management’s assumptions of various factors, such as future interest rates, expected stock market performance, budgeted option costs, lapses, and annuitizations. Management’s assumptions are adjusted for emerging experience and expected trends, resulting in changes to the estimated fair value of the embedded derivatives. Auditing management’s estimate of the fair value of the embedded derivatives related to fixed-indexed annuity products was complex because it required the involvement of our actuarial specialists due to the highly judgmental nature of the assumptions used in the valuation process. The significant judgment was primarily due to the sensitivity of the budgeted option costs and lapse assumptions.

How We Addressed the Matter in Our Audit We obtained an understanding, evaluated the design, and tested the operating effectiveness of controls over the process for estimating the embedded derivatives. This included, among others, the review and approval processes that management has in place for the methods and assumptions used in the valuation process of the embedded derivatives.

To test the embedded derivatives related to fixed-indexed annuity products, our procedures included, among others, testing the completeness and accuracy of data used in the valuation process through testing the reconciliation of the underlying data recorded in the source systems to the actuarial valuation models. With the assistance of our actuarial specialists, we evaluated the methods and assumptions used by management in determining the estimated fair value of the embedded derivatives. We compared the significant assumptions, including expected budget option costs and lapses, to prior actual experience and management’s estimates of prospective changes in these assumptions. In addition, we performed an independent calculation of the embedded derivatives for a sample of policies for comparison with the fair value calculated by the actuarial model used by management.

A.     Accounting Policies

Basis of Presentation   The consolidated financial statements include the accounts of American Financial Group, Inc. and its subsidiaries (“AFG”). Certain reclassifications have been made to prior years 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 December 31, 2019, and prior to the filing of this Form 10-K, have been evaluated for potential recognition or disclosure herein.

The preparation of the financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) 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.

On January 1, 2018, AFG adopted Accounting Standards Update (“ASU”) 2014-09, which provides guidance on recognizing revenue when (or as) performance obligations under the contract are satisfied. The guidance also updates the accounting for certain costs associated with obtaining and fulfilling contracts with customers and requires certain new disclosures. Because revenue recognition for insurance contracts and financial instruments (AFG’s primary sources of revenue) were excluded from the scope of the new guidance, the adoption of ASU 2014-09 did not have a material impact on AFG’s results of operations or financial position.

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 2019 or 2018.

Investments   On January 1, 2018, AFG adopted ASU 2016-01, which requires all equity securities other than those accounted for under the equity method to be reported at fair value with holding gains and losses recognized in net earnings. At December 31, 2017, AFG had $1.60 billion in equity securities classified as “available for sale” under the prior guidance with holding gains and losses included in accumulated other comprehensive income (“AOCI”) instead of net earnings. At the date of adoption, the $221 million net unrealized gain on equity securities included in AOCI was reclassified to retained earnings as the cumulative effect of an accounting change. The cumulative effect of the accounting change also includes the net unrealized gain on AFG’s small number of limited partnerships and similar investments carried at cost under the prior guidance that are carried at fair value through net earnings under the new guidance ($4 million net of tax at the date of adoption).

Following the adoption of ASU 2016-01, holding gains and losses on equity securities carried at fair value are generally recorded in realized gains (losses) on securities. However, AFG records holding gains and losses on securities classified as “trading” under previous guidance, its small portfolio of limited partnerships and similar investments carried at fair value and certain other securities classified at purchase as “fair value through net investment income” in net investment income.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED

Under the new guidance, AFG recorded holding gains of $207 million on equity securities in net earnings during 2019 on securities still held at December 31, 2019 and holding losses of $257 million on equity securities in net earnings during 2018 on securities that were still owned at December 31, 2018. Under the prior guidance, these holding losses would have been recorded in AOCI until the securities were disposed (with exception of any impairment charge that may have been recorded). Because almost all of the equity securities impacted by the new guidance were carried at fair value through AOCI under the prior guidance, the adoption of the new guidance did not have a material impact on AFG’s financial position.

Fixed maturity securities classified as “available for sale” are reported at fair value with unrealized gains and losses included in 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 and policy loans are carried primarily at the aggregate unpaid balance.

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 they are 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.

Gains or losses on fixed maturity securities classified as “available for sale” are determined on the specific identification basis. When a decline in the value of a specific investment is considered to be other-than-temporary at the balance sheet date, a provision for impairment is charged to earnings (included in realized gains (losses) on securities) and the cost basis of that investment is reduced. If management can assert that it does not intend to sell an impaired fixed maturity security and it is not more likely than not that it will have to sell the security before recovery of its amortized cost basis, then the other-than-temporary impairment is separated into two components: (i) the amount 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 of an other-than-temporary impairment 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 impairment charge. Both components are shown in the statement of earnings. 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 charge to earnings is recorded to reduce the amortized cost of that security to fair value.

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. Derivatives that do not qualify for hedge accounting under GAAP consist primarily of (i) components of certain fixed maturity securities (primarily interest-only and principal-only MBS) and (ii) the equity-based component of certain annuity products (included in annuity benefits accumulated) and related equity index options designed to be consistent with the characteristics of the liabilities and used to mitigate the risk embedded in those annuity products.

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 and ineffectiveness will be measured on a retrospective and prospective basis.

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 included in AFG’s portfolio of fixed maturity securities.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED

Goodwill   Goodwill represents the excess of cost of subsidiaries over AFG’s equity in their underlying net assets. 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’s property and casualty insurance subsidiaries report 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’s property and casualty insurance subsidiaries under contracts to fund ceded losses as they become due. AFG’s insurance subsidiaries also assume reinsurance from other companies. Earnings on reinsurance assumed is recognized based on information received from ceding companies.

An AFG subsidiary cedes life insurance policies to a third-party on a funds withheld basis whereby the subsidiary retains the assets (securities) associated with the reinsurance contract. Interest is credited to the reinsurer based on the actual investment performance of the retained assets. This reinsurance contract is considered to contain an embedded derivative (that must be adjusted to fair value) because the yield on the payable is based on a specific block of the ceding company’s assets, rather than the overall creditworthiness of the ceding company. AFG determined that changes in the fair value of the underlying portfolio of fixed maturity securities is an appropriate measure of the value of the embedded derivative. The securities related to this contract are classified as “trading.” The adjustment to fair value on the embedded derivative offsets the investment income recorded on the adjustment to fair value of the related trading portfolio.

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 also includes capitalized costs associated with sales inducements offered to fixed annuity policyholders such as enhanced interest rates and premium and persistency bonuses.

For the property and casualty companies, 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.

DPAC related to annuities is deferred to the extent deemed recoverable and amortized, with interest, in relation to the present value of actual and expected gross profits on the policies. Expected gross profits consist principally of estimated future investment margin (estimated future net investment income less interest credited on policyholder funds) and surrender, mortality, and other life and annuity policy charges, less death, annuitization and guaranteed withdrawal benefits in excess of account balances and estimated future policy administration expenses. To the extent that realized gains and losses result in adjustments to the amortization of DPAC related to annuities, such adjustments are reflected as components of realized gains (losses) on securities.

DPAC related to traditional life and health insurance is amortized over the expected premium paying period of the related policies, in proportion to the ratio of annual premium revenues to total anticipated premium revenues. See “Life, Accident and Health Reserves” below for details on the impact of loss recognition on the accounting for traditional life and health insurance contracts.

DPAC includes the present value of future profits on business in force of annuity and life, accident and health insurance companies acquired (“PVFP”). PVFP represents the portion of the costs to acquire companies that is allocated to the value of the right to receive future cash flows from insurance contracts existing at the date of acquisition. PVFP is amortized with interest in relation to expected gross profits of the acquired policies for annuities and universal life products and in relation to the premium paying period for traditional life and health insurance products.

DPAC and certain other balance sheet amounts related to annuity and life businesses are also adjusted, net of tax, for the change in expense that would have been recorded if the unrealized gains (losses) from securities had actually been realized. These adjustments are included in unrealized gains (losses) on marketable securities, a component of AOCI in AFG’s Balance Sheet.

AMERICAN FINANCIAL GROUP, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED

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 H — “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.

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.

Annuity Benefits Accumulated   Annuity receipts and benefit payments are recorded as increases or decreases in annuity benefits accumulated rather than as revenue and expense. Increases in this liability for interest credited are charged to annuity benefits expense and decreases for annuity policy charges are recorded in other income. For traditional fixed annuities, the liability for annuity benefits accumulated represents the account value that had accrued to the benefit of the policyholder as of the balance sheet date. For fixed-indexed annuities (“FIAs”), the liability for annuity benefits accumulated includes an embedded derivative that represents the estimated fair value of the index participation with the remaining component representing the discounted value of the guaranteed minimum contract benefits.

For certain products, annuity benefits accumulated also includes reserves for accrued persistency and premium bonuses, guaranteed withdrawals and excess benefits expected to be paid on future deaths and annuitizations (“EDAR”). The liabilities for EDAR and guaranteed withdrawals are accrued for and modified using assumptions consistent with those used in determining DPAC and DPAC amortization, except that amounts are determined in relation to the present value of total expected assessments. Total expected assessments consist principally of estimated future investment margin, surrender, mortality, and other life and annuity policy charges, and unearned revenues once they are recognized as income.

Annuity benefits accumulated also includes amounts advanced from the Federal Home Loan Bank of Cincinnati.

AMERICAN FINANCIAL GROUP, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED

Unearned Revenue   Certain upfront policy charges on annuities are deferred as unearned revenue (included in other liabilities) and recognized in net earnings (included in other income) using the same assumptions and estimated gross profits used to amortize DPAC.

Life, Accident and Health Reserves   Liabilities for future policy benefits under traditional life, accident and health policies are computed using the net level premium method. Computations are based on the original projections of investment yields, mortality, morbidity and surrenders and include provisions for unfavorable deviations unless a loss recognition event (premium deficiency) occurs. Claim reserves and liabilities established for accident and health claims are modified as necessary to reflect actual experience and developing trends.

For long-duration contracts (such as traditional life and long-term care policies), loss recognition occurs when, based on current expectations as of the measurement date, existing contract liabilities plus the present value of future premiums (including reasonably expected rate increases) are not expected to cover the present value of future claims payments and related settlement and maintenance costs (excluding overhead) as well as unamortized acquisition costs. If a block of business is determined to be in loss recognition, a charge is recorded in earnings in an amount equal to the excess of the present value of expected future claims costs and unamortized acquisition costs over existing reserves plus the present value of expected future premiums (with no provision for adverse deviation). The charge is recorded first to reduce unamortized acquisition costs and then as an additional reserve (if unamortized acquisition costs have been reduced to zero).

In addition, reserves for traditional life and long-term care policies are subject to adjustment for loss recognition charges that would have been recorded if the unrealized gains (losses) from securities had actually been realized. This adjustment is included in unrealized gains (losses) on marketable securities, a component of AOCI in AFG’s Balance Sheet.

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.

Variable Annuity Assets and Liabilities   Separate accounts related to variable annuities represent the fair value of deposits invested in underlying investment funds on which AFG earns a fee. Investment funds are selected and may be changed only by the policyholder, who retains all investment risk.

AFG’s variable annuity contracts contain a guaranteed minimum death benefit (“GMDB”) to be paid if the policyholder dies before the annuity payout period commences. In periods of declining equity markets, the GMDB may exceed the value of the policyholder’s account. A GMDB liability is established for future excess death benefits using assumptions together with a range of reasonably possible scenarios for investment fund performance that are consistent with DPAC capitalization and amortization assumptions.

Leases   On January 1, 2019, AFG adopted ASU 2016-02, which requires entities that lease assets for terms longer than one year to recognize 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. As permitted under the ASU, AFG adopted the guidance on a modified retrospective basis (comparative periods were not adjusted) and elected the following accounting policies and practical expedients:

• exclude leases with a term of 12 months or less from the calculation of lease assets and liabilities,

• not separate lease and non-lease components except for buildings (office space and storage facilities),

• for contracts existing at the date of adoption – not reassess whether a contract is a lease or contains a lease, how initial direct costs were accounted for or whether the lease is an operating or finance lease, and

• use hindsight to determine the lease term for leases existing at the date of adoption.

Adoption of the new guidance resulted in AFG recognizing a lease liability of $198 million (included in other liabilities) and a corresponding right-of-use asset of $174 million (included in other assets and presented net of $24 million in deferred rent and lease incentives) on January 1, 2019. Deferred rent and lease incentives were recognized as liabilities under the previous guidance and result from the straight-line expensing of operating leases. The adoption of the new guidance did not have a material effect on the AFG’s results of operations or liquidity. See Note K — “Leases” for additional disclosures.

Noncontrolling Interests   For balance sheet purposes, noncontrolling interests represent the interests of shareholders other than AFG in consolidated entities. In the statement of earnings, net earnings and losses attributable to noncontrolling interests represents such shareholders’ interest in the earnings and losses of those entities. Noncontrolling

F-13

AMERICAN FINANCIAL GROUP, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED

interests that are redeemable at the option of the holder are presented separately in the mezzanine section of the balance sheet (between liabilities and equity).

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. For traditional life, accident and health products, premiums are recognized as revenue when legally collectible from policyholders. For interest-sensitive life and universal life products, premiums are recorded in a policyholder account, which is reflected as a liability. Revenue is recognized as amounts are assessed against the policyholder account for mortality coverage and contract expenses.

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.

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.

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. This includes the impact on deferred tax assets or liabilities established through AOCI, which results in an amount equal to the difference between the deferred tax at the historical corporate rate and the newly enacted rate stranded in AOCI. As permitted under guidance adopted effective December 31, 2017 (ASU 2018-02), AFG reclassified the $145 million stranded in AOCI from accounting for the Tax Cuts and Jobs Act of 2017 to retained earnings at December 31, 2017. See Note M — “Income Taxes” for further information.

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 uses the Black-Scholes pricing model to measure the fair value of employee stock options.

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: 2019 – 1.1 million, 2018 – 1.6 million and 2017 – 2.0 million.

There were no anti-dilutive potential common shares related to stock compensation plans or adjustments to net earnings attributable to shareholders in the calculation of diluted earnings per share for the years ended December 31, 2019, 2018 or 2017.

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. Annuity receipts, surrenders, benefits and withdrawals are also reflected as financing activities. 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.

Credit Impairment Guidance Effective in 2020 In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments, which provides a new loss model for determining credit-related impairments for financial instruments measured at amortized cost (mortgage loans, premiums receivable and reinsurance recoverables) and requires an entity to estimate the 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, will be 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. The updated guidance also amends the current other-than-temporary impairment model for available for sale debt securities by requiring the recognition of impairments relating to credit losses through an allowance account and limits the amount of credit loss to the difference between a security’s amortized cost basis and its fair value. Subsequent increases or decreases in expected credit losses will be recorded immediately in net earnings through realized gains (losses). AFG will adopt this guidance effective January 1, 2020. The new guidance is not expected to have a material impact on AFG’s results of operations or financial position.

B.     Acquisitions and Sale of Businesses

Atlas Financial Holdings, Inc.   In June 2019, National Interstate, a property and casualty insurance subsidiary of AFG, entered into an agreement with Atlas Financial Holdings, Inc. (“AFH”) to become the exclusive underwriter of AFH’s paratransit book of business. National Interstate estimates that the majority of AFH’s $110 million paratransit business will be eligible for quotation under this arrangement over the first 12 months following inception of the agreement. Under the terms of the agreement, AFH will act as an underwriting manager for National Interstate for at least 12 months, after which time National Interstate is entitled to acquire the renewal rights for the business from AFH for a purchase price equal to 15% of the in force gross written premiums at that date. The majority of the purchase price ultimately paid for the renewal rights will be recorded as an intangible renewal rights asset and will be amortized over the estimated life of the business acquired. In connection with the transaction, AFG was granted a five-year warrant to acquire approximately 2.4 million shares of AFH (19.9% at the acquisition date). The estimated fair value of the warrant was approximately $1 million at the date it was received.

ABA Insurance Services Inc.   In November 2018, AFG acquired ABA Insurance Services Inc. (“ABAIS”) from American Bankers Mutual Insurance, Ltd. for approximately $30 million using cash on hand at the parent company. Additional contingent consideration of up to $3 million could be due four years after the acquisition date based on achieving certain operating milestones. ABAIS is based in Ohio and is a market-leading provider of directors and officers liability and other complementary insurance solutions for banks, small businesses and nonprofit organizations.

The allocation of the purchase price is shown in the table below (in millions):

	November 30, 2018
Total purchase price	$	30
Tangible assets acquired	28

Approximately $25 million of the purchase price was recorded as a finite lived customer relationship intangible asset, which will be amortized over its estimated life of 9 years. The fair value of this intangible was estimated using a multi-period excess earnings method, which is a form of the income approach. The acquisition resulted in the recognition of $8 million in goodwill based on the excess of the purchase price over the fair value of the net assets acquired. The goodwill represents the fair value of acquired intangible assets that do not qualify for separate recognition, including the value of ABAIS’s assembled workforce. Business generated by ABAIS is included in the Specialty casualty sub-segment.

Neon Lloyd’s Business   In December 2017, AFG completed the sale of an indirect noncontrolling interest in Neon, its United Kingdom-based Lloyd’s insurer, to certain Neon executives for cash equal to the fair value of the interest sold as determined by a third-party valuation firm. Because AFG continues to have a controlling interest in Neon, the sale was accounted for as an equity transaction with the excess of the carrying value of the net assets attributable to the noncontrolling interest sold over the consideration received recorded as a $3 million reduction in AFG’s Capital Surplus. As discussed in Note M — “Income Taxes,” the sale of the noncontrolling interest also resulted in the recognition of a $56 million tax benefit, including a $48 million tax benefit previously deferred in the 2016 restructuring of the Neon Lloyd’s operations.

C.    Segments of Operations

AFG manages its business as three segments: (i) Property and casualty insurance, (ii) Annuity and (iii) Other, which includes holding company assets and costs, revenues and costs of AFG’s limited insurance operations outside of property and casualty insurance and annuity segments, 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, 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 deferred gains on retroactive reinsurance transactions related to the sales of businesses in prior years. AFG’s annuity business sells traditional fixed and indexed annuities in the retail, financial institutions, broker-dealer and registered investment advisor markets. AFG’s reportable segments and their components were determined based primarily upon similar economic characteristics, products and services.

Sales of property and casualty insurance outside of the United States represented 7% of AFG’s revenues in 2019 and in 2018 and 5% of AFG’s revenues in 2017. Approximately two-thirds of these 2019 sales were through the Neon Lloyd’s of London business, which AFG is exiting and will no longer write property and casualty business (beginning in early 2020).

D.    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 separate account assets, corporate and municipal fixed maturity securities, asset-backed securities (“ABS”), mortgage-backed securities (“MBS”), certain non-affiliated common stocks, equity index options 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.

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 analysts 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, the Company 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.

The transfers between Level 1 and Level 2 for the years ended December 31, 2019, 2018 and 2017 are reflected in the table below at fair value as of the end of the reporting period (dollars in millions):

Common stocks	1	—	—	—		—		—		—	—	1	—		—		—

Transfers between Level 1 and Level 2 for all periods presented were a result of increases or decreases in observable trade activity.

Approximately 7% of the total assets carried at fair value on December 31, 2019, were Level 3 assets. Approximately 57% ($2.17 billion) of the 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.

Internally developed Level 3 asset fair values represent approximately $1.36 billion at December 31, 2019. Of this amount, approximately $716 million relates to fixed maturity securities that were priced using management’s best estimate of an appropriate credit spread over the treasury yield (of a similar duration) to discount future expected cash flows using a third-party model. The credit spread applied by management is the significant unobservable input. For this group of approximately 35 securities, the average spread used was 396 basis points over the reference treasury yield and the spreads ranged from 100 basis points to 1,253 basis points (approximately 70% of the spreads were between 200 and 700 basis points). Had management used higher spreads, the fair value of this group of securities would have been lower. Conversely, if the spreads used were lower, the fair values would have been higher. For the remainder of the internally developed prices, any justifiable changes in unobservable inputs used to determine fair value would not have resulted in a material change in AFG’s financial position.

The derivatives embedded in AFG’s fixed-indexed and variable-indexed annuity liabilities are measured using a discounted cash flow approach and had a fair value of $3.73 billion at December 31, 2019. The following table presents information about the unobservable inputs used by management in determining fair value of these Level 3 liabilities. See Note F — “Derivatives.”

Unobservable Input	Range
Adjustment for insurance subsidiary’s credit risk	0.2% – 2.4% over the risk-free rate
Risk margin for uncertainty in cash flows	0.80% reduction in the discount rate
Surrenders	3% – 22% of indexed account value
Partial surrenders	2% – 9% of indexed account value
Annuitizations	0.1% – 1% of indexed account value
Deaths	1.5% – 10.6% of indexed account value
Budgeted option costs	2.5% – 3.3% of indexed account value

The range of adjustments for insurance subsidiary’s credit risk is based on the Moody’s corporate A2 bond index and reflects credit spread variations across the yield curve. The range of projected surrender rates reflects the specific surrender charges and other features of AFG’s individual fixed-indexed and variable-indexed annuity products with an expected range of 7% to 10% in the majority of future calendar years (3% to 22% over all periods). Increasing the budgeted option cost or risk margin for uncertainty in cash flow assumptions in the table above would increase the fair value of the fixed-indexed and variable-indexed annuity embedded derivatives, while increasing any of the other unobservable inputs in the table above would decrease the fair value of the embedded derivatives.

The transfers into and out of Level 3 were due to changes in the availability of market observable inputs and $29 million of equity securities transferred into Level 3 in the first quarter of 2018 related to a small number of limited partnerships and similar investments carried at cost under the prior guidance that are carried at fair value through net earnings under new guidance adopted on January 1, 2018, as discussed in Note A — “Accounting Policies — Investments.” All transfers are reflected in the table at fair value as of the end of the reporting period.

The non-credit related portion of other-than-temporary impairment charges is included in other comprehensive income. Cumulative non-credit charges taken for securities still owned at December 31, 2019 and December 31, 2018 were $118 million and $140 million, respectively. Gross unrealized gains on such securities at December 31, 2019 and December 31, 2018 were $114 million and $119 million, respectively. Gross unrealized losses on such securities at December 31, 2019 and December 31, 2018 were $1 million and $4 million, respectively. These amounts represent the non-credit other-than-temporary impairment charges recorded in AOCI adjusted for subsequent changes in fair values and relate primarily to residential MBS.

At December 31, 2019, the gross unrealized losses on fixed maturities of $88 million relate to 649 securities. Investment grade securities (as determined by nationally recognized rating agencies) represented approximately 74% of the gross unrealized loss and 93% of the fair value.

The determination of whether unrealized losses are other-than-temporary requires judgment based on subjective as well as objective factors. Factors considered and resources used by management include:

a) whether the unrealized loss is credit-driven or a result of changes in market interest rates,

b) the extent to which fair value is less than cost basis,

c) cash flow projections received from independent sources,

d) historical operating, balance sheet and cash flow data contained in issuer SEC filings and news releases,

e) near-term prospects for improvement in the issuer and/or its industry,

f) third-party research and communications with industry specialists,

g) financial models and forecasts,

h) the continuity of interest payments, maintenance of investment grade ratings and hybrid nature of certain investments,

i) discussions with issuer management, and

j) ability and intent to hold the investment for a period of time sufficient to allow for anticipated recovery in fair value.

AFG analyzes its MBS securities for other-than-temporary 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. During 2019, 2018 and 2017, AFG recorded other-than-temporary impairment charges related to its residential MBS of $1 million, $6 million and $1 million, respectively.

F-26

AMERICAN FINANCIAL GROUP, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED

In 2019, AFG recorded other-than-temporary impairment charges of $17 million on third-party collateralized loan obligations and $11 million on corporate bonds. Other-than-temporary impairment charges on fixed maturities other than residential MBS were $20 million in 2018 and $19 million in 2017. In addition, AFG recorded $4 million in other-than-temporary impairment charges in 2017 on investments that are included in other investments on the balance sheet.

Management believes AFG will recover its cost basis 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 December 31, 2019.

As discussed in Note A — “Accounting Policies — Investments,” effective January 1, 2018, all equity securities previously classified as “available for sale” are required to be carried at fair value through net earnings instead of accumulated other comprehensive income and therefore are no longer evaluated for other-than-temporary impairment. In 2017, AFG recorded other-than-temporary impairment charges on equity securities classified as available for sale of $64 million.

A progression of the credit portion of other-than-temporary impairments on fixed maturity securities for which the non-credit portion of an impairment has been recognized in other comprehensive income is shown below (in millions):

	2019			2018			2017
Balance at January 1	$	142		$	145		$	153
Additional credit impairments on:
Previously impaired securities	1			1			1

Reductions due to sales or redemptions	(9		)	(5		)	(12		)
Balance at December 31	$	134		$	142		$	145

The table below sets forth the scheduled maturities of available for sale fixed maturities as of December 31, 2019 (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.

	Amortized		Fair Value

Total	$	44,524	$	46,505	100	%

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 December 31, 2019 or 2018.

Net Unrealized Gain on Marketable Securities   In addition to adjusting fixed maturity securities classified as “available for sale” to fair value, GAAP requires that deferred policy acquisition costs and certain other balance sheet amounts related to annuity, long-term care and life businesses be adjusted to the extent that unrealized gains and losses from securities would result in adjustments to those balances had the unrealized gains or losses actually been realized. The following table shows (in millions) the components of the net unrealized gain on securities that is included in AOCI in AFG’s Balance Sheet.

F.    Derivatives

As discussed under “Derivatives” in Note A — “Accounting Policies,” AFG uses derivatives in certain areas of its operations.

Derivatives That Do Not Qualify for Hedge Accounting   The following derivatives that do not qualify for hedge accounting under GAAP are included in AFG’s Balance Sheet at fair value (in millions):

		December 31, 2019				December 31, 2018
Derivative	Balance Sheet Line	Asset		Liability		Asset		Liability
MBS with embedded derivatives	Fixed maturities	$	102	$	—	$	109	$	—
Public company warrants	Equity securities	—		—		—		—
Fixed-indexed and variable-indexed annuities (embedded derivative)	Annuity benefits accumulated	—		3,730		—		2,720
Equity index call options	Equity index call options	924		—		184		—
Equity index put options	Other liabilities	—		1		—		1
Reinsurance contract (embedded derivative)	Other liabilities	—		4		—		2
		$	1,026	$	3,735	$	293	$	2,723

The MBS with embedded derivatives consist of primarily interest-only and principal-only MBS. AFG records the entire 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.

Warrants to purchase shares of publicly traded companies, which represent a small component of AFG’s overall investment portfolio, are considered to be derivatives that are required to be carried at fair value through earnings.

AFG’s fixed-indexed and variable-indexed annuities provide policyholders with a crediting rate tied, in part, to the performance of an existing stock market or other financial index. AFG attempts to mitigate the risk in the index-based component of these products through the purchase and sale of call and put options on the appropriate index. AFG receives collateral from certain counterparties to support its purchased call option assets (net of collateral required under put option contracts with the same counterparties). This collateral ($577 million at December 31, 2019 and $103 million at December 31, 2018) is included in other assets in AFG’s Balance Sheet with an offsetting liability to return the collateral, which is included in other liabilities. AFG’s strategy is designed so that the net change in the fair value of the call and put options will generally offset the economic change in the net liability from the index participation. Both the index-based component of the annuities (an embedded derivative) and the related call and put options are considered derivatives that must be adjusted for changes in fair value through earnings each period. The fair values of these derivatives are impacted by actual and expected stock market performance and interest rates as well as other factors. Fluctuations in certain of these factors, such as changes in interest rates and the performance of the stock market, are not economic in nature for the current reporting period, but rather impact the timing of reported results.

As discussed under “Reinsurance” in Note A, AFG has a reinsurance contract that is considered to contain an embedded derivative.

The following table summarizes the gains (losses) included in AFG’s Statement of Earnings for changes in the fair value of derivatives that do not qualify for hedge accounting for 2019, 2018 and 2017 (in millions):

Derivative	Statement of Earnings Line	2019			2018			2017
MBS with embedded derivatives	Realized gains (losses) on securities	$	10		$	(7	)	$	(6	)
Public company warrants	Realized gains (losses) on securities	(1		)	(3		)	—
Fixed-indexed and variable-indexed annuities (embedded derivative) (*)	Annuity benefits	(919		)	204			(589		)
Equity index call options	Annuity benefits	804			(298		)	494
Equity index put options	Annuity benefits	2			(1		)	—
Reinsurance contracts (embedded derivative)	Net investment income	(2		)	2			(2		)
		$	(106	)	$	(103	)	$	(103	)

(*) The change in fair value of the embedded derivative includes a favorable adjustment related to unlocking of actuarial assumptions of $181 million in 2019 and losses of $44 million in 2018 and $25 million in 2017.

Derivatives Designated and Qualifying as Cash Flow Hedges   As of December 31, 2019, AFG has thirteen active 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 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 LIBOR.

Under the terms of the swaps, AFG receives fixed-rate interest payments in exchange for variable interest payments based on short-term LIBOR. The notional amounts of the interest rate swaps generally decline over each swap’s respective life (the swaps expire between April 2020 and June 2030) in anticipation of the expected decline in AFG’s portfolio of fixed maturity securities with floating interest rates based on short-term LIBOR. The total outstanding notional amount of AFG’s interest rate swaps was $1.98 billion at December 31, 2019 compared to $2.35 billion at December 31, 2018, reflecting the scheduled amortization discussed above, the termination of two swaps with notional amounts of $138 million and $100 million (on the settlement dates) in the second quarter and fourth quarter of 2019, respectively, and the expiration of a swap with a notional amount of $78 million (on the expiration date) in the third quarter of 2019. The fair value of the interest rate swaps in an asset position and included in other assets was $50 million at December 31, 2019 and $16 million at December 31, 2018. The fair value of the interest rate swaps in a liability position and included in other liabilities was $5 million at December 31, 2019 and $46 million at December 31, 2018. The net unrealized gain or loss on cash flow hedges is included in AOCI, net of DPAC and deferred taxes. Amounts reclassified from AOCI (before DPAC and taxes) to net investment income were income of $3 million in 2019, losses of $3 million in 2018 and income of $6 million in 2017. A collateral receivable supporting these swaps of $20 million at December 31, 2019 and $135 million at December 31, 2018 is included in other assets in AFG’s Balance Sheet.

The present value of future profits (“PVFP”) amounts in the table above are net of $154 million and $148 million of accumulated amortization at December 31, 2019 and 2018, respectively. During each of the next five years, the PVFP is expected to decrease at a rate of approximately one-eighth of the balance at the beginning of each respective year.

H.    Managed Investment Entities

AFG is the investment manager and its subsidiaries have investments ranging from 15.0% to 60.9% of the most subordinate debt tranche of eleven active collateralized loan obligation entities (“CLOs”), which are considered variable interest entities. AFG’s subsidiaries also own portions of the senior debt tranches of certain of these CLOs. Upon formation between 2012 and 2018, 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 $165 million (including $102 million invested in the most subordinate tranches) at December 31, 2019, and $188 million at December 31, 2018.

During 2019, AFG subsidiaries received less than $1 million in redemption proceeds from their CLO investments. In 2018, AFG formed a new CLO, which issued $463 million face amount of liabilities (including $31 million face amount purchased by subsidiaries of AFG). During 2018, AFG subsidiaries also purchased $7 million face amount of a senior debt tranche of an existing CLO for $7 million and received $45 million in sale and redemption proceeds from its CLO investments. In 2017, AFG formed two new CLOs, which issued an aggregate of $865 million face amount of liabilities (including $48 million face amount purchased by subsidiaries of AFG). During 2017, AFG subsidiaries also purchased $71 million face amount of senior debt and subordinate tranches of existing CLOs for $71 million and received $103 million in sale and redemption proceeds from its CLO investments. In 2018 and 2017, one and two AFG CLOs, respectively, were substantially liquidated, as permitted by the CLO indentures.

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 shareholders of 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): 

	Year ended December 31,
	2019			2018			2017
Investment in CLO tranches	$	165		$	188		$	215
Gains (losses) on change in fair value of assets/liabilities (a):
Assets	80			(189		)	(8		)
Liabilities	(110		)	168			20
Management fees paid to AFG	15			16			18
CLO earnings attributable to AFG Shareholders (b)	4			7			23

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

(b) Included in earnings before income taxes 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 $146 million and $232 million at December 31, 2019 and 2018, respectively. The aggregate unpaid principal balance of the CLOs’ debt exceeded its carrying value by $129 million and $241 million at those dates. The CLO assets include loans with an aggregate fair value of $10 million at December 31, 2019, for which the CLOs are not accruing interest because the loans are in default (aggregate unpaid principal balance of $25 million; none at December 31, 2018).

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 carrying value of $4.28 billion at both December 31, 2019 and December 31, 2018.

I.    Goodwill and Other Intangibles

Changes in the carrying value of goodwill during 2017, 2018 and 2019, by reporting segment, are presented in the following table (in millions):

	Property and Casualty		Annuity		Total
Balance at January 1, 2017 and December 31, 2017	$	168	$	31	$	199
Acquisition of subsidiary in 2018	8		—		8
Balance at December 31, 2018 and December 31, 2019	$	176	$	31	$	207

Goodwill increased by $8 million in the fourth quarter of 2018 due to the purchase of ABAIS as discussed in Note B — “Acquisitions and Sale of Businesses.”

Included in other assets in AFG’s Balance Sheet is $43 million at December 31, 2019 and $54 million at December 31, 2018 of amortizable intangible assets related to property and casualty insurance acquisitions. These amounts are net of accumulated amortization of $50 million and $39 million, respectively. The increase in amortizable intangible assets in 2018 relates to the November 2018 acquisition of ABAIS (discussed in Note B — “Acquisitions and Sale of Businesses”) and a renewal rights intangible asset established in connection with the acquisition of a small property and casualty book of business in January 2018. Amortization of intangibles was $11 million in 2019, $9 million in 2018 and $8 million in 2017. Future amortization of intangibles (weighted average amortization period of 4 years) is estimated to be $12 million in 2020, $6 million in 2021, $4 million per year in 2022, 2023 and 2024 and $13 million thereafter.

J.    Long-Term Debt

AFG has no scheduled principal payments on its long-term debt in the next five years.

In December 2019, AFG issued $200 million in 5.125% Subordinated Debentures due in 2059. The net proceeds of the offering were used, in part, to redeem AFG’s $150 million outstanding principal amount of 6-1/4% Subordinated Debentures due September 2054 at par value in December 2019.

In March 2019, AFG issued $125 million in 5.875% Subordinated Debentures due in 2059.

AFG can borrow up to $500 million under its revolving credit facility, which expires in June 2021. Amounts borrowed under this agreement bear interest at rates ranging from 1.00% to 1.875% (currently 1.375%) over LIBOR based on AFG’s credit rating. No amounts were borrowed under this facility at December 31, 2019 or December 31, 2018.

Cash interest payments on long-term debt were $65 million in 2019, $59 million in 2018 and $85 million in 2017.

K.    Leases

AFG and its subsidiaries lease real estate that is primarily used for office space and, to a lesser extent, equipment under operating lease arrangements. Most of AFG’s real estate leases include an option to extend or renew the lease term at AFG’s option. The operating lease liability includes lease payments related to options to extend or renew the lease term if AFG is reasonably certain of exercising those options. Lease payments are discounted using the implicit discount rate in the lease. If the implicit discount rate for the lease cannot be readily determined, AFG uses an estimate of its incremental secured borrowing rate. AFG did not have any material contracts accounted for as finance leases at December 31, 2019 or January 1, 2019.

At December 31, 2019, AFG’s $158 million operating lease right-of-use asset (presented net of $22 million in deferred rent and lease incentives) and $180 million operating lease liability are included in other assets and other liabilities, respectively, in AFG’s Balance Sheet.

The following table details AFG’s lease activity for the year ended December 31, 2019 (in millions):

AFG issued 45,804 shares (fair value of $115.49 per share) in the first quarter of 2018 under its Equity Bonus Plan.

AFG has not granted any stock options since 2015. Options granted in prior years have an exercise price equal to the market price of AFG Common Stock at the date of grant. Options generally become exercisable at the rate of 20% per year commencing one year after grant and expire ten years after the date of grant.

Data for stock options issued under AFG’s stock incentive plans is presented below:

	Shares		Average Exercise Price		Average Remaining Contractual Term	Aggregate Intrinsic Value (in millions)
Outstanding at January 1, 2019	2,667,442		$	48.20

Options exercisable at December 31, 2019	1,779,941		$	50.13	3.6 years	$	107

The total intrinsic value of options exercised during 2019, 2018 and 2017 was $46 million, $57 million and $65 million, respectively. During 2019, 2018 and 2017, AFG received $31 million, $29 million and $34 million, respectively, in cash from the exercise of stock options. The total tax benefit related to the exercises was $8 million, $9 million and $18 million during those years, respectively.

Total compensation expense related to stock incentive plans of AFG and its subsidiaries was $23 million for 2019 and 2018 and $30 million for 2017. AFG’s provision for income tax includes tax benefits of $13 million in 2019 and 2018 and $27 million in 2017 related to AFG’s stock incentive plans. At December 31, 2019, there was $36 million of unrecognized compensation expense related to restricted stock awards, which is expected to be recognized over a weighted average of 2.4 years. At December 31, 2019, there was less than $1 million of unrecognized compensation expense related to unvested stock options, which will be recognized in the first quarter of 2020.

(c) On January 1, 2018, AFG adopted new guidance that requires all equity securities other than those accounted for under the equity method to be reported at fair value with holding gains and losses recognized in net earnings. At the date of adoption, the $221 million net unrealized gain on equity securities classified as available for sale (with unrealized holding gains and losses reported in AOCI) under the prior guidance was reclassified from AOCI to retained earnings as the cumulative effect of an accounting change. Other also includes the December 2017 reclassification of $145 million stranded in AOCI from accounting for the Tax Cuts and Jobs Act of 2017 to retained earnings (see Note A — “Accounting Policies — Income Taxes”) and the impact on AOCI of the December 2017 sale of redeemable noncontrolling interests in Neon.

M.    Income Taxes

The following is a reconciliation of income taxes at the statutory rate (21% in 2019 and 2018 and 35% in 2017) to the provision for income taxes as shown in AFG’s Statement of Earnings (dollars in millions):

In January 2008, AFG paid $75 million in cash to acquire approximately 67% of Neon Underwriting Limited (“Neon”, formerly known as Marketform Group Limited), a United Kingdom-based Lloyd’s insurer. During 2012, AFG acquired the then-remaining shares of Neon that it did not already own for $17 million. AFG’s investment in Neon includes the cost of acquiring the company as well as additional capital provided to Neon since the date of acquisition.

In 2011, cumulative losses at Neon across multiple lines of business resulted in uncertainty concerning the realization of the deferred tax benefits associated with the losses. Consequently, AFG began maintaining a full valuation allowance against the deferred tax assets related to the Lloyd’s insurance business in 2011.

Approximately $14 million of the $21 million impact of “foreign operations” for 2017 in the table above relates to a reduction in the “foreign underwriting losses” deferred tax asset as a result of the sale of the noncontrolling interest in Neon. Since AFG maintains a full valuation allowance against the deferred tax assets related to Neon, this reduction in deferred tax assets was offset by a corresponding reduction in the valuation allowance and had no overall impact on AFG’s income tax expense or results of operations.

The changes in valuation allowance in the table above are primarily increases in the valuation allowance on tax benefits related to losses in the Neon Lloyd’s insurance business. The $61 million decrease in the valuation allowance in 2017 related to the change in the U.S. corporate tax rate is included in “Change in U.S. corporate tax rate” in table above.

The sale of the noncontrolling interest in Neon in the fourth quarter of 2017 resulted in the recognition of a tax benefit of $56 million, including the recognition of a deferred loss from the 2016 restructuring of Neon. Approximately $20 million of the $56 million tax benefit recorded in 2017 reduced current taxes payable for 2017. The majority of the remaining 2017

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED

tax benefit is expected to be received in 2020 as a result of the filing of a refund claim in 2018 to carry back tax basis capital losses to offset prior year tax basis capital gains.

The Tax Cuts and Jobs Act of 2017 (“TCJA”), which was enacted on December 22, 2017, lowered the U.S corporate tax rate to 21% and made other widespread changes to the U.S. tax code effective in 2018. Because the TCJA was enacted in December 2017, AFG recorded the $83 million decrease in its net deferred tax asset resulting from the changes in the tax code (primarily the lower corporate tax rate applicable to 2018 and future years) in the fourth quarter of 2017.

In addition to the lower U.S. corporate tax rate, the TCJA implemented a new global minimum tax on income earned by foreign subsidiaries of U.S.-based entities known as the Global Intangible Low-taxed Income (“GILTI”) provision. Since almost all of AFG’s earnings are taxable based on U.S. tax rates, the GILTI is not expected to be material to AFG’s results of operations and will be recorded in the period that any tax arises.

At the time it was enacted, the TCJA was subject to further clarification and interpretation by the U.S. Treasury Department and the Internal Revenue Service. AFG’s deferred tax assets and liabilities were recorded at December 31, 2017 using reasonable estimates based on available information and were considered provisional in accordance with Securities and Exchange Commission Staff Accounting Bulletin No. 118 (“SAB 118”). In accordance with SAB 118, changes in deferred taxes resulting from clarification and interpretation of the TCJA were recorded in 2018 in the period in which the guidance was published and did not have a material impact on AFG’s effective tax rate. As a result, AFG’s implementation of the TCJA was complete as of December 31, 2018.

Excluding the tax benefit related to the Neon restructuring and the impact of the change in the U.S. corporate tax rate, AFG’s effective tax rate for the year ended December 31, 2017 was 31%.

AFG’s 2013 — 2019 tax years remain subject to examination by the IRS.

Total earnings before income taxes include losses subject to tax in foreign jurisdictions of $109 million in 2019, $69 million in 2018 and $58 million in 2017, primarily related to the Neon Lloyd’s operations.

The total income tax provision (credit) consists of (in millions):

AFG’s net deferred tax asset at December 31, 2019 and 2018 is included in other assets in AFG’s Balance Sheet. The decrease in AFG’s net deferred tax asset at December 31, 2019 compared to December 31, 2018 reflects significantly higher pretax unrealized gains on securities.

The likelihood of realizing deferred tax assets is reviewed periodically; any adjustments required to the valuation allowance are made in the period during which developments requiring an adjustment become known.

“Foreign underwriting losses” in the table above is primarily the net operating loss carryforward and other deferred tax assets related to the Neon Lloyd’s insurance business. Due to uncertainty concerning the realization of the deferred tax benefits associated with these losses, AFG maintains a full valuation allowance of $118 million against these deferred tax assets at December 31, 2019. In addition to the valuation allowance related to the Neon Lloyd’s insurance business, the gross deferred tax asset has also been reduced by a $19 million valuation allowance related to AFG’s net operating loss carryforwards (“NOL”) subject to the separate return limitation year (“SRLY”) tax rules. A SRLY NOL can be used only by the entity that created it and only in years that both it and the consolidated group have taxable income. Approximately $19 million of AFG’s SRLY NOLs expired unutilized at December 31, 2019. Since AFG maintains a full valuation allowance against its SRLY NOLs, the expiration of these loss carryforwards was offset by corresponding reduction in the valuation allowance and had no overall impact on AFG’s income tax expense or results of operations.

AFG increased its liability for uncertain tax positions by $1 million in 2015 due to uncertainty in state taxation of its surplus lines insurance subsidiaries. In 2017, this uncertainty was resolved, resulting in total tax payments of less than $1 million.

A progression of the liability for uncertain tax positions, excluding interest and penalties, follows (in millions):

At December 31, 2019, there are no unrecognized tax benefits and related interest and penalties that, if recognized, would impact the effective tax rate. The total unrecognized tax benefits and related interest and penalties that, if recognized, would impact the effective tax rate was less than $1 million at December 31, 2018. There is no interest expense related to unrecognized tax benefits included in AFG’s provision for income taxes in 2019; AFG’s provision for income taxes in 2018 and 2017 included interest expense related to unrecognized tax benefits of less than $1 million in each year (net of federal benefit or expense). There is no liability for interest related to unrecognized tax benefits at December 31, 2019 or December 31, 2018. AFG’s provision for income taxes in 2019, 2018 and 2017 included penalties of less than $1 million in each year. There is no liability for penalties related to unrecognized tax benefits at December 31, 2019; AFG’s liability for penalties related to unrecognized tax benefits was less than $1 million at December 31, 2018.

Cash payments for income taxes, net of refunds, were $278 million, $156 million and $194 million for 2019, 2018 and 2017, respectively.

N.     Contingencies

Establishing property and casualty insurance reserves for claims related to environmental exposures, asbestos and other mass tort claims is subject to uncertainties that are significantly greater than those presented by other types of claims. For this group of claims, traditional actuarial techniques that rely on historical loss development trends cannot be used and a range of reasonably possible losses cannot be estimated. In addition, accruals (included in other liabilities) have been recorded for various environmental and occupational injury and disease claims and other contingencies arising out of the railroad operations disposed of by American Premier’s predecessor, Penn Central Transportation Company (“PCTC”) and its subsidiaries, prior to its bankruptcy reorganization in 1978 and certain manufacturing operations disposed of by American Premier and Great American Financial Resources, Inc. (“GAFRI”).

AFG completed an in-depth internal review of its asbestos and environmental (“A&E”) exposures in the third quarter of 2019. The review resulted in special A&E charges of $18 million for the property and casualty group and $11 million for the former railroad and manufacturing operations. AFG also completed an in-depth internal review of its A&E exposures in the third quarter of 2018, which resulted in special A&E charges of $18 million for the property and casualty group and $9 million for the former railroad and manufacturing operations. AFG completed a comprehensive external study of its A&E exposures in the third quarter of 2017 with the aid of specialty actuarial, engineering and consulting firms and outside counsel. The study resulted in special A&E charges of $89 million for the property and casualty group and $24 million for the former railroad and manufacturing operations.

The property and casualty group’s liability for A&E reserves was $529 million at December 31, 2019; related recoverables from reinsurers (net of allowances for doubtful accounts) at that date were $146 million.

At December 31, 2019, American Premier and its subsidiaries had liabilities for environmental and personal injury claims and other contingencies aggregating $84 million. The environmental claims consist of a number of proceedings and claims seeking to impose responsibility for hazardous waste remediation costs related to certain sites formerly owned or operated by the railroad and manufacturing operations. Remediation costs are difficult to estimate for a number of reasons, including the number and financial resources of other potentially responsible parties, the range of costs for remediation alternatives, changing technology and the time period over which these matters develop. The personal injury claims and other contingencies include pending and expected claims, primarily by former employees of PCTC, for injury or disease allegedly caused by exposure to excessive noise, asbestos or other substances in the workplace and other labor disputes.

At December 31, 2019, GAFRI had a liability of $8 million for environmental costs and certain other matters associated with the sales of its former manufacturing operations.

In December 2015, AFG completed the sale of substantially all of its run-off long-term care insurance business to HC2 Holdings, Inc. (“HC2”). In connection with obtaining regulatory approval for the transaction, AFG agreed to provide up to an aggregate of $35 million of capital support for the insurance companies, on an as-needed basis to maintain specified surplus levels, subject to immediate reimbursement by HC2 through a five-year capital maintenance agreement expiring in 2020.

While management believes AFG has recorded adequate reserves for the items discussed above, the outcome is uncertain and could result in liabilities that may vary from amounts AFG has currently recorded. Such amounts could have a material effect on AFG’s future results of operations and financial condition.

In addition, AFG and its subsidiaries are involved in litigation from time to time, generally arising in the ordinary course of business. This litigation may include, but is not limited to, general commercial disputes, lawsuits brought by policyholders, employment matters, reinsurance collection matters and actions challenging certain business practices of insurance subsidiaries. None of these matters are expected to have a material adverse impact on AFG’s results of operations or financial condition.

O.     Quarterly Operating Results (Unaudited)

The operations of certain AFG business segments are seasonal in nature. While insurance premiums are recognized on a relatively level basis, claim losses related to adverse weather (snow, hail, hurricanes, severe storms, tornadoes, etc.) may be seasonal. The profitability of AFG’s crop insurance business is primarily recognized during the second half of the year as crop prices and yields are determined. Quarterly results necessarily rely heavily on estimates. These estimates and certain other factors, such as the discretionary sales of assets, cause the quarterly results not to be necessarily indicative of results for longer periods of time.

The following are quarterly results of consolidated operations for the two years ended December 31, 2019 (in millions, except per share amounts). Quarterly earnings per share do not add to year-to-date amounts due to changes in shares outstanding.

FIAs provide policyholders with a crediting rate tied, in part, to the performance of an existing stock market or other financial index. AFG attempts to mitigate the risk in the index-based component of these products through the purchase and sale of call and put options on the appropriate index. AFG’s strategy is designed so that the change in the fair value of the call and put options will generally offset the economic change in the liabilities from the index participation. Both the index-based component of the annuities and the related call and put options are considered derivatives that must be

marked-to-market through earnings each period. Fluctuations in interest rates and the stock market, among other factors, can cause volatility in the periodic measurement of these derivatives and other FIA liabilities over or under the cost of the equity index options purchased to mitigate the risk in the index-based component of those FIAs.

The impact of unlocking, changes in the fair value of derivatives related to FIAs, and other impacts of changes in the stock market and interest rates on the accounting for FIAs over or under the cost of the equity index options purchased to mitigate the risk in the index-based component of those FIAs were as follows, net of the related acceleration/deceleration of the amortization of deferred policy acquisition costs and deferred sales inducements (in millions):

2018	15			(14		)	17			(66		)	(48		)

Favorable prior year development of AFG’s liability for property and casualty losses and loss adjustment expenses (”LAE”) was as follows (in millions):

	1st Quarter		2nd Quarter		3rd Quarter		4th Quarter		Total Year
2019	$	45	$	41	$	12	$	45	$	143
2018	56		44		31		61		192

Prior year development in both the third quarters of 2019 and 2018 includes pretax special charges of $18 million to strengthen property and casualty insurance A&E reserves.

In the fourth quarter of 2019, AFG recorded a pretax charge of $76 million for reserve strengthening and expenses related to exit costs incurred with AFG’s plans to exit the Lloyd’s of London insurance market in 2020.

AFG’s property and casualty operations recorded catastrophe losses, including reinstatement premiums, as follows (in millions):

	1st Quarter			2nd Quarter			3rd Quarter			4th Quarter			Total Year
2019	$	(12	)	$	(12	)	$	(22	)	$	(15	)	$	(61	)
2018	(13		)	(16		)	(38		)	(38		)	(105		)

Results for the third quarter of 2019 and 2018 include pretax special charges of $11 million and $9 million, respectively, to strengthen reserves for A&E exposures related to AFG’s former railroad and manufacturing operations.

AFG recorded a pretax loss on the retirement of debt of $5 million in the fourth quarter of 2019.

Holding company expenses were $20 million higher in the fourth quarter of 2019 compared to the fourth quarter of 2018 due primarily to higher expenses related to employee benefit plans that are tied to stock market performance.

P.     Insurance

Cash and securities owned by U.S.-based insurance subsidiaries, having a carrying value of approximately $1.04 billion at December 31, 2019, were on deposit as required by regulatory authorities. In addition, $217 million was on deposit in support of AFG’s underwriting activities at Lloyd’s. At December 31, 2019, AFG and its subsidiaries had $414 million in undrawn letters of credit (none of which was collateralized) and similar agreements supporting the underwriting capacity of its U.K.-based Lloyd’s insurer, Neon.

Property and Casualty Insurance Reserves   Estimating the liability for unpaid losses and loss adjustment expenses (“LAE”) is inherently judgmental and is influenced by factors that are subject to significant variation. Determining the liability is a complex process incorporating input from many areas of the Company including actuarial, underwriting, pricing, claims and operations management.

The process used to determine the total reserve for liabilities involves estimating the ultimate incurred losses and LAE, adjusted for amounts already paid on the claims. The IBNR reserve is derived by first estimating the ultimate unpaid reserve liability and subtracting case reserves for loss and LAE.

F-43

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED

In determining management’s best estimate of the ultimate liability, management (with the assistance of Company actuaries) considers items such as the effect of inflation on medical, hospitalization, material, repair and replacement costs, the nature and maturity of lines of insurance, general economic trends and the legal environment. In addition, historical trends adjusted for changes in underwriting standards, policy provisions, product mix and other factors are analyzed using actuarial reserve development techniques. Weighing all of the factors, the management team determines a single or “point” estimate that it records as its best estimate of the ultimate liability. Ranges of loss reserves are not developed by Company actuaries. This reserve analysis and review is completed each quarter and for almost every business within AFG’s property and casualty insurance sub-segments.

Each review includes in-depth analysis of several hundred subdivisions of the business, employing multiple actuarial techniques. For each subdivision, actuaries use informed, professional judgment to adjust these techniques as necessary to respond to specific conditions in the data or within the business.

Some of the standard actuarial methods employed for the quarterly reserve analysis may include (but may not be limited to):

• Case Incurred Development Method

• Paid Development Method

• Bornhuetter-Ferguson Method

• Incremental Paid LAE to Paid Loss Methods

Management believes that each method has particular strengths and weaknesses and that no single estimation method is most accurate in all situations. When applied to a particular group of claims, the relative strengths and weaknesses of each method can change over time based on the facts and circumstances. Ultimately, the estimation methods chosen are those which management believes produce the most reliable indication for the particular liabilities under review.

The period of time from the occurrence of a loss through the settlement of the liability is referred to as the “tail”. Generally, the same actuarial methods are considered for both short-tail and long-tail lines of business because most of them work properly for both. The methods are designed to incorporate the effects of the differing length of time to settle particular claims. For short-tail lines, management tends to give more weight to the Case Incurred and Paid Development methods, although the various methods tend to produce similar results. For long-tail lines, more judgment is involved, and more weight may be given to the Bornhuetter-Ferguson method. Liability claims for long-tail lines are more susceptible to litigation and can be significantly affected by changing contract interpretation and the legal environment. Therefore, the estimation of loss reserves for these classes is more complex and subject to a higher degree of variability.

The level of detail in which data is analyzed varies among the different lines of business. Data is generally analyzed by major product or by coverage within product, using countrywide data; however, in some situations, data may be reviewed by state or region. Appropriate segmentation of the data is determined based on data credibility, homogeneity of development patterns, mix of business, and other actuarial considerations.

Supplementary statistical information is also reviewed to determine which methods are most appropriate to use or if adjustments are needed to particular methods. Such information includes:

• Open and closed claim counts

• Average case reserves and average incurred on open claims

• Closure rates and statistics related to closed and open claim percentages

• Average closed claim severity

• Ultimate claim severity

• Reported loss ratios

• Projected ultimate loss ratios

• Loss payment patterns

Within each business, results of individual methods are reviewed, supplementary statistical information is analyzed, and data from underwriting, operating and claim management are considered in deriving management’s best estimate of the ultimate liability. This estimate may be the result of one method, a weighted average of several methods, or a judgmental selection as the management team determines is appropriate.

The liability for losses and LAE for a very limited number of claims with long-term scheduled payments under certain workers’ compensation policies has been discounted at 4.5% at both December 31, 2019 and 2018, which represents an approximation of long-term investment yields. Because of the limited amount of claims involved, the net impact of

discounting did not materially impact AFG’s total liability for unpaid losses and loss adjustment expenses (net reductions from discounting of $12 million and $13 million at December 31, 2019 and 2018, respectively).

The following table provides an analysis of changes in the liability for losses and loss adjustment expenses over the past three years (in millions):

(*) Reflects the reinsurance to close transactions at Neon (discussed below).

The net decrease in the provision for claims of prior years in 2019 reflects (i) lower than expected claim frequency and severity at National Interstate and lower than expected losses in the crop business (all within the Property and transportation sub-segment), (ii) lower than anticipated claim frequency and severity in the workers’ compensation businesses (within the Specialty casualty sub-segment), and (iii) lower than expected claim frequency and severity in the surety and financial institutions businesses and lower than anticipated claim severity in the foreign credit business (all within the Specialty financial sub-segment). This favorable development was partially offset by (i) the $18 million special charge to increase asbestos and environmental reserves and adverse reserve development of $7 million on Neon’s exited lines of business, (ii) higher than expected claim severity in the excess and surplus lines businesses and higher than expected claim frequency in product liability contractor claims (all within the Specialty casualty sub-segment), and (iii) net adverse reserve development related to business outside the Specialty group that AFG no longer writes.

The net decrease in the provision for claims of prior years in 2018 reflects (i) lower than expected losses in the crop business and lower than expected claim severity at National Interstate (within the Property and transportation sub-segment), (ii) lower than anticipated claim severity in the workers’ compensation businesses, lower than expected emergence in assumed 2017 property catastrophe losses at Neon and lower than expected claim severity in the executive liability business (within the Specialty casualty sub-segment) and (iii) lower than expected claim frequency and severity in the surety business, lower than expected claim severity in the fidelity business and lower than expected claim frequency in run-off businesses (within the Specialty financial sub-segment). This favorable development was partially offset by (i) the $18 million special charge to increase asbestos and environmental reserves and (ii) higher than expected claim frequency and severity in the Singapore branch and aviation operations (within the Property and transportation sub-segment).

The net decrease in the provision for claims of prior years in 2017 reflects (i) lower than expected losses in the crop and equine businesses and lower than expected claim severity in the property and inland marine and transportation businesses (all within the Property and transportation sub-segment), (ii) favorable reserve development of $18 million on Neon’s exited lines, as well as additional favorable development on ongoing lines of business within Neon, recorded in connection with the reinsurance to close agreement entered into in December 2017 for the 2015 and prior years of account, lower than anticipated claim severity in the workers’ compensation businesses and lower than expected losses in the executive liability business (all within the Specialty casualty sub-segment) and (iii) lower than anticipated claim severity in the fidelity business and lower than expected claim frequency and severity in the surety business (both within the Specialty financial sub-segment). This favorable development was partially offset by (i) the $89 million special charge

to increase asbestos and environmental reserves, (ii) higher than expected claim frequency and severity in the ocean marine business (within the Property and transportation sub-segment), (iii) higher than anticipated claim severity in the targeted markets and general liability businesses and higher than anticipated severity in New York contractor claims (all within the Specialty casualty sub-segment) and (iv) a charge to adjust to the deferred gain on the retroactive reinsurance transaction entered into in connection with the sale of businesses in 1998 (included in Other specialty sub-segment).

In December 2017, the Neon Lloyd’s syndicate entered into a reinsurance to close transaction for the 2015 and prior years of account with StarStone Underwriting Limited, a subsidiary of Enstar Group Limited, which was effective as of December 31, 2017 and settled in early 2018. In the Lloyd’s market, a reinsurance to close transaction transfers the responsibility for discharging all of the liabilities that attach to the transferred year of account plus the right to any income due to the closing year of account in return for a premium. This transaction provided Neon with finality on its legacy business. As a result of the reinsurance to close agreement, Neon was able to better estimate its ultimate liability for the 2015 and prior years of account as of December 31, 2017, resulting in favorable development of $42 million, of which $24 million related to its ongoing lines of business (included in Specialty casualty) and $18 million related to its exited lines of business.

A reconciliation of incurred and paid claims development information to the aggregate carrying amount of the liability for unpaid losses and LAE, with separate disclosure of reinsurance recoverables on unpaid claims is shown below (in millions):

The following claims development tables and associated disclosures related to short-duration insurance contracts are prepared by sub-segment within the property and casualty insurance business for the most recent 10 accident years. AFG determines its claim counts at the claimant or policy feature level depending on the particular facts and circumstances of the underlying claim. While the methodology is generally consistent within each sub-segment, there are minor differences between and within the sub-segments. The methods used to summarize claim counts have not changed significantly over the time periods reported in the tables below.

AFG’s remaining outstanding long-term care policies have level premiums and are guaranteed renewable. Premium rates can potentially be increased in reaction to adverse experience; however, any rate increases would require regulatory approval.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED

FHLB Funding Agreements   Great American Life Insurance Company (“GALIC”), a wholly-owned annuity subsidiary, is a member of the Federal Home Loan Bank of Cincinnati (“FHLB”). The FHLB makes advances and provides other banking services to member institutions. Members are required to purchase stock in the FHLB in addition to maintaining collateral deposits that back any funds advanced. GALIC’s $52 million investment in FHLB capital stock at December 31, 2019 is included in other investments at cost. Membership in the FHLB provides the annuity operations with an additional source of liquidity. These advances further the FHLB’s mission of improving access to housing by increasing liquidity in the residential mortgage-backed securities market.

In 2019, GALIC refinanced the terms on advances totaling $610 million. In the fourth quarter of 2018, GALIC refinanced the terms on a $40 million advance and the FHLB advanced GALIC $225 million. At both December 31, 2019 and December 31, 2018, GALIC had $1.10 billion in outstanding advances from the FHLB (included in annuity benefits accumulated), bearing interest at rates ranging from 0.13% to 0.21% over LIBOR (average rate of 1.95% at December 31, 2019). While these advances must be repaid between 2020 and 2021 ($310 million in 2020 and $786 million in 2021), GALIC has the option to prepay all or a portion of the advances. GALIC has invested the proceeds from the advances in fixed maturity securities with similar expected lives as the advances for the purpose of earning a spread over the interest payments due to the FHLB. The advances on these agreements are collateralized by fixed maturity investments, which have a total fair value of $1.27 billion (included in available for sale fixed maturity securities) at December 31, 2019. Interest credited on the funding agreements, which is included in annuity benefits, was $27 million in 2019, $20 million in 2018 and $14 million in 2017.

Statutory Information   AFG’s U.S.-based insurance subsidiaries are required to file financial statements with state insurance regulatory authorities prepared on an accounting basis prescribed or permitted by such authorities (statutory basis). Net earnings and capital and surplus on a statutory basis for the insurance subsidiaries were as follows (in millions):

	Net Earnings						Capital and Surplus
	2019		2018		2017		2019		2018
Property and casualty companies	$	584	$	546	$	484	$	3,342	$	2,867
Life (annuity) insurance companies	34		802		286		2,868		2,701

In the fourth quarter of 2018, GALIC, AFG’s primary annuity subsidiary, entered into a reinsurance treaty with Hannover Life Reassurance Company of America that transfers the risk of certain surrender activity in GALIC’s fixed-indexed annuity business. This treaty meets the statutory risk transfer rules and resulted in a $510 million increase in statutory surplus (through an after-tax reserve credit), which is reflected in the life insurance companies capital and surplus in the table above. Under GAAP, this transaction does not meet the GAAP insurance risk transfer criteria and did not have a material impact on AFG’s financial statements.

The National Association of Insurance Commissioners’ (“NAIC”) model law for risk-based capital (“RBC”) applies to both life and property and casualty insurance companies. RBC formulas determine the amount of capital that an insurance company needs so that it has an acceptable expectation of not becoming financially impaired. Companies below specific trigger points or ratios are subject to regulatory action. At December 31, 2019 and 2018, the capital ratios of all AFG insurance companies substantially exceeded the RBC requirements. AFG’s insurance companies did not use any prescribed or permitted statutory accounting practices that differed from the NAIC statutory accounting practices at December 31, 2019 or 2018.

Payments of dividends by AFG’s insurance companies are subject to various state laws that limit the amount of dividends that can be paid. Under applicable restrictions, the maximum amount of dividends available to AFG in 2020 from its insurance subsidiaries without seeking regulatory approval is $852 million. Additional amounts of dividends require regulatory approval.

Holding Company Dividends   AFG declared and paid common stock dividends to shareholders totaling $446 million, $397 million and $421 million in 2019, 2018 and 2017, respectively. Currently, there are no regulatory restrictions on AFG’s retained earnings or net earnings that materially impact its ability to pay dividends. Based on shareholders’ equity at December 31, 2019, AFG could pay dividends in excess of $2.5 billion without violating its most restrictive debt covenant. However, the payment of future dividends will be at the discretion of AFG’s Board of Directors and will be dependent on many factors including AFG’s financial condition and results of operations, the capital requirements of its insurance subsidiaries, and rating agency commitments.

Reinsurance   In the normal course of business, AFG’s insurance subsidiaries cede reinsurance to other companies to diversify risk and limit maximum loss arising from large claims. However, AFG remains liable to its insureds regardless of whether a reinsurer is able to meet its obligations. The following table shows (in millions) (i) amounts deducted from property and casualty written and earned premiums in connection with reinsurance ceded, (ii) written and earned premiums included in income for reinsurance assumed and (iii) reinsurance recoveries, which represent ceded losses and loss adjustment expenses.

	2019			2018			2017
Direct premiums written	$	7,044		$	6,626		$	6,310
Reinsurance assumed	255			214			192
Reinsurance ceded	(1,957		)	(1,817		)	(1,751		)
Net written premiums	$	5,342		$	5,023		$	4,751
Direct premiums earned	$	6,848		$	6,472		$	6,112
Reinsurance assumed	226			204			157
Reinsurance ceded	(1,889		)	(1,811		)	(1,690		)
Net earned premiums	$	5,185		$	4,865		$	4,579
Reinsurance recoveries	$	1,404		$	1,249		$	1,379

In June 2017, AFG’s property and casualty insurance subsidiaries entered into a reinsurance agreement to obtain supplemental catastrophe protection through a catastrophe bond structure with Riverfront Re Ltd. (“Riverfront”). The reinsurance agreement provides supplemental reinsurance coverage up to 95% of $200 million (fully collateralized) for catastrophe losses in excess of $134 million of traditional catastrophe reinsurance (per occurrence and annual aggregate) occurring until December 31, 2020. In connection with the reinsurance agreement, Riverfront issued notes to unrelated investors for the full amount of coverage provided under the reinsurance agreement. Through December 31, 2019, AFG’s incurred catastrophe losses have not reached the level of attachment for the catastrophe bond structure. Riverfront is a variable interest entity in which AFG does not have a variable interest because the variability in Riverfront’s results will be absorbed entirely by the investors in Riverfront. Accordingly, Riverfront is not consolidated in AFG’s financial statements and the reinsurance agreement is accounted for as ceded reinsurance. AFG’s cost for this coverage is approximately $11 million per year.

AFG has reinsured approximately $6.23 billion of its $9.53 billion in face amount of life insurance at December 31, 2019 compared to $7.69 billion of its $10.82 billion in face amount of life insurance at December 31, 2018. Life written premiums ceded were $20 million, $22 million and $28 million for 2019, 2018 and 2017, respectively. Reinsurance recoveries on ceded life policies were $32 million, $38 million and $35 million for 2019, 2018 and 2017, respectively.

Fixed Annuities   For certain products, the liability for “annuity benefits accumulated” includes reserves for excess benefits expected to be paid on future deaths and annuitizations guaranteed withdrawal benefits and accrued persistency and premium bonuses. The liabilities included in AFG’s Balance Sheet for these benefits, excluding the impact of unrealized gains on securities, were as follows at December 31 (in millions):

	2019		2018
Expected death and annuitization	$	232	$	229
Guaranteed withdrawal benefits	625		472
Accrued persistency and premium bonuses	1		1

Variable Annuities   At December 31, 2019, the aggregate guaranteed minimum death benefit value (assuming every variable annuity policyholder died on that date) on AFG’s variable annuity policies exceeded the fair value of the underlying variable annuities by $13 million, compared to $35 million at December 31, 2018. Death benefits paid in excess of the variable annuity account balances were less than $1 million in each of the last three years ended December 31, 2019, 2018 and 2017.

Q.     Additional Information

Allowance for Uncollectible Reinsurance   AFG’s aggregate allowance for uncollectible reinsurance recoverables was $18 million at both December 31, 2019 and December 31, 2018. AFG reviews the allowance quarterly and adjusts it as necessary to reflect changes in estimates of uncollectible balances. AFG recorded net expense reductions against the allowance of less than $1 million in 2019, $2 million in 2018 and less than $1 million in 2017. In 2017, the allowance was reduced by reinsurance recoverable write-offs of $2 million.

See Note A — “Accounting Policies — Credit Impairment Guidance Effective in 2020” for a discussion of accounting guidance adopted on January 1, 2020, which provides a new credit loss model for determining credit-related impairments for reinsurance recoverables and requires an entity to estimate the credit losses expected over the life of an exposure or pool of exposures. The new guidance is not expected to have a material impact on AFG’s results of operations or financial position.

Financial Instruments — Unfunded Commitments   On occasion, AFG and its subsidiaries have entered into financial instrument transactions that may present off-balance-sheet risks of both a credit and market risk nature. These transactions include commitments to fund loans, loan guarantees and commitments to purchase and sell securities or loans. At December 31, 2019, AFG and its subsidiaries had commitments to fund credit facilities and contribute capital to limited partnerships and limited liability corporations of approximately $897 million.

Benefit Plans   AFG expensed approximately $39 million in 2019, $37 million in 2018 and $45 million in 2017 for its retirement and employee savings plans.

[1] The reclassification adjustment out of net unrealized gains (losses) on securities affected the following lines in AFG’s Statement of Earnings:   OCI component   Affected line in the statement of earnings     Pretax   Realized gains (losses) on securities     Tax   Provision for income taxes  

[2] Includes net unrealized gains of $55 million at December 31, 2019 compared to $58 million and $68 million at December 31, 2018 and 2017, related to securities for which only the credit portion of an other-than-temporary impairment has been recorded in earnings.

[3] On January 1, 2018, AFG adopted new guidance that requires all equity securities other than those accounted for under the equity method to be reported at fair value with holding gains and losses recognized in net earnings. At the date of adoption, the $221 million net unrealized gain on equity securities classified as available for sale (with unrealized holding gains and losses reported in AOCI) under the prior guidance was reclassified from AOCI to retained earnings as the cumulative effect of an accounting change. Other also includes the December 2017 reclassification of $145 million stranded in AOCI from accounting for the Tax Cuts and Jobs Act of 2017 to retained earnings (see Note A — “Accounting Policies — Income Taxes”) and the impact on AOCI of the December 2017 sale of redeemable noncontrolling interests in Neon.

Accounting Policies [Abstract]

Accounting Policies

Accounting Policies

Basis of Presentation   The consolidated financial statements include the accounts of American Financial Group, Inc. and its subsidiaries (“AFG”). Certain reclassifications have been made to prior years 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 December 31, 2019, and prior to the filing of this Form 10-K, have been evaluated for potential recognition or disclosure herein.

The preparation of the financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) 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.

On January 1, 2018, AFG adopted Accounting Standards Update (“ASU”) 2014-09, which provides guidance on recognizing revenue when (or as) performance obligations under the contract are satisfied. The guidance also updates the accounting for certain costs associated with obtaining and fulfilling contracts with customers and requires certain new disclosures. Because revenue recognition for insurance contracts and financial instruments (AFG’s primary sources of revenue) were excluded from the scope of the new guidance, the adoption of ASU 2014-09 did not have a material impact on AFG’s results of operations or financial position.

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 2019 or 2018.

Investments   On January 1, 2018, AFG adopted ASU 2016-01, which requires all equity securities other than those accounted for under the equity method to be reported at fair value with holding gains and losses recognized in net earnings. At December 31, 2017, AFG had $1.60 billion in equity securities classified as “available for sale” under the prior guidance with holding gains and losses included in accumulated other comprehensive income (“AOCI”) instead of net earnings. At the date of adoption, the $221 million net unrealized gain on equity securities included in AOCI was reclassified to retained earnings as the cumulative effect of an accounting change. The cumulative effect of the accounting change also includes the net unrealized gain on AFG’s small number of limited partnerships and similar investments carried at cost under the prior guidance that are carried at fair value through net earnings under the new guidance ($4 million net of tax at the date of adoption).

Following the adoption of ASU 2016-01, holding gains and losses on equity securities carried at fair value are generally recorded in realized gains (losses) on securities. However, AFG records holding gains and losses on securities classified as “trading” under previous guidance, its small portfolio of limited partnerships and similar investments carried at fair value and certain other securities classified at purchase as “fair value through net investment income” in net investment income.

Under the new guidance, AFG recorded holding gains of $207 million on equity securities in net earnings during 2019 on securities still held at December 31, 2019 and holding losses of $257 million on equity securities in net earnings during 2018 on securities that were still owned at December 31, 2018. Under the prior guidance, these holding losses would have been recorded in AOCI until the securities were disposed (with exception of any impairment charge that may have been recorded). Because almost all of the equity securities impacted by the new guidance were carried at fair value through AOCI under the prior guidance, the adoption of the new guidance did not have a material impact on AFG’s financial position.

Fixed maturity securities classified as “available for sale” are reported at fair value with unrealized gains and losses included in 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 and policy loans are carried primarily at the aggregate unpaid balance.

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 they are 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.

Gains or losses on fixed maturity securities classified as “available for sale” are determined on the specific identification basis. When a decline in the value of a specific investment is considered to be other-than-temporary at the balance sheet date, a provision for impairment is charged to earnings (included in realized gains (losses) on securities) and the cost basis of that investment is reduced. If management can assert that it does not intend to sell an impaired fixed maturity security and it is not more likely than not that it will have to sell the security before recovery of its amortized cost basis, then the other-than-temporary impairment is separated into two components: (i) the amount 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 of an other-than-temporary impairment 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 impairment charge. Both components are shown in the statement of earnings. 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 charge to earnings is recorded to reduce the amortized cost of that security to fair value.

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. Derivatives that do not qualify for hedge accounting under GAAP consist primarily of (i) components of certain fixed maturity securities (primarily interest-only and principal-only MBS) and (ii) the equity-based component of certain annuity products (included in annuity benefits accumulated) and related equity index options designed to be consistent with the characteristics of the liabilities and used to mitigate the risk embedded in those annuity products.

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 and ineffectiveness will be measured on a retrospective and prospective basis.

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 included in AFG’s portfolio of fixed maturity securities.

Goodwill   Goodwill represents the excess of cost of subsidiaries over AFG’s equity in their underlying net assets. 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’s property and casualty insurance subsidiaries report 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’s property and casualty insurance subsidiaries under contracts to fund ceded losses as they become due. AFG’s insurance subsidiaries also assume reinsurance from other companies. Earnings on reinsurance assumed is recognized based on information received from ceding companies.

An AFG subsidiary cedes life insurance policies to a third-party on a funds withheld basis whereby the subsidiary retains the assets (securities) associated with the reinsurance contract. Interest is credited to the reinsurer based on the actual investment performance of the retained assets. This reinsurance contract is considered to contain an embedded derivative (that must be adjusted to fair value) because the yield on the payable is based on a specific block of the ceding company’s assets, rather than the overall creditworthiness of the ceding company. AFG determined that changes in the fair value of the underlying portfolio of fixed maturity securities is an appropriate measure of the value of the embedded derivative. The securities related to this contract are classified as “trading.” The adjustment to fair value on the embedded derivative offsets the investment income recorded on the adjustment to fair value of the related trading portfolio.

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 also includes capitalized costs associated with sales inducements offered to fixed annuity policyholders such as enhanced interest rates and premium and persistency bonuses.

For the property and casualty companies, 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.

DPAC related to annuities is deferred to the extent deemed recoverable and amortized, with interest, in relation to the present value of actual and expected gross profits on the policies. Expected gross profits consist principally of estimated future investment margin (estimated future net investment income less interest credited on policyholder funds) and surrender, mortality, and other life and annuity policy charges, less death, annuitization and guaranteed withdrawal benefits in excess of account balances and estimated future policy administration expenses. To the extent that realized gains and losses result in adjustments to the amortization of DPAC related to annuities, such adjustments are reflected as components of realized gains (losses) on securities.

DPAC related to traditional life and health insurance is amortized over the expected premium paying period of the related policies, in proportion to the ratio of annual premium revenues to total anticipated premium revenues. See “Life, Accident and Health Reserves” below for details on the impact of loss recognition on the accounting for traditional life and health insurance contracts.

DPAC includes the present value of future profits on business in force of annuity and life, accident and health insurance companies acquired (“PVFP”). PVFP represents the portion of the costs to acquire companies that is allocated to the value of the right to receive future cash flows from insurance contracts existing at the date of acquisition. PVFP is amortized with interest in relation to expected gross profits of the acquired policies for annuities and universal life products and in relation to the premium paying period for traditional life and health insurance products.

DPAC and certain other balance sheet amounts related to annuity and life businesses are also adjusted, net of tax, for the change in expense that would have been recorded if the unrealized gains (losses) from securities had actually been realized. These adjustments are included in unrealized gains (losses) on marketable securities, a component of AOCI in AFG’s Balance Sheet.

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 H — “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.

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.

Annuity Benefits Accumulated   Annuity receipts and benefit payments are recorded as increases or decreases in annuity benefits accumulated rather than as revenue and expense. Increases in this liability for interest credited are charged to annuity benefits expense and decreases for annuity policy charges are recorded in other income. For traditional fixed annuities, the liability for annuity benefits accumulated represents the account value that had accrued to the benefit of the policyholder as of the balance sheet date. For fixed-indexed annuities (“FIAs”), the liability for annuity benefits accumulated includes an embedded derivative that represents the estimated fair value of the index participation with the remaining component representing the discounted value of the guaranteed minimum contract benefits.

For certain products, annuity benefits accumulated also includes reserves for accrued persistency and premium bonuses, guaranteed withdrawals and excess benefits expected to be paid on future deaths and annuitizations (“EDAR”). The liabilities for EDAR and guaranteed withdrawals are accrued for and modified using assumptions consistent with those used in determining DPAC and DPAC amortization, except that amounts are determined in relation to the present value of total expected assessments. Total expected assessments consist principally of estimated future investment margin, surrender, mortality, and other life and annuity policy charges, and unearned revenues once they are recognized as income.

Annuity benefits accumulated also includes amounts advanced from the Federal Home Loan Bank of Cincinnati.

Unearned Revenue   Certain upfront policy charges on annuities are deferred as unearned revenue (included in other liabilities) and recognized in net earnings (included in other income) using the same assumptions and estimated gross profits used to amortize DPAC.

Life, Accident and Health Reserves   Liabilities for future policy benefits under traditional life, accident and health policies are computed using the net level premium method. Computations are based on the original projections of investment yields, mortality, morbidity and surrenders and include provisions for unfavorable deviations unless a loss recognition event (premium deficiency) occurs. Claim reserves and liabilities established for accident and health claims are modified as necessary to reflect actual experience and developing trends.

For long-duration contracts (such as traditional life and long-term care policies), loss recognition occurs when, based on current expectations as of the measurement date, existing contract liabilities plus the present value of future premiums (including reasonably expected rate increases) are not expected to cover the present value of future claims payments and related settlement and maintenance costs (excluding overhead) as well as unamortized acquisition costs. If a block of business is determined to be in loss recognition, a charge is recorded in earnings in an amount equal to the excess of the present value of expected future claims costs and unamortized acquisition costs over existing reserves plus the present value of expected future premiums (with no provision for adverse deviation). The charge is recorded first to reduce unamortized acquisition costs and then as an additional reserve (if unamortized acquisition costs have been reduced to zero).

In addition, reserves for traditional life and long-term care policies are subject to adjustment for loss recognition charges that would have been recorded if the unrealized gains (losses) from securities had actually been realized. This adjustment is included in unrealized gains (losses) on marketable securities, a component of AOCI in AFG’s Balance Sheet.

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.

Variable Annuity Assets and Liabilities   Separate accounts related to variable annuities represent the fair value of deposits invested in underlying investment funds on which AFG earns a fee. Investment funds are selected and may be changed only by the policyholder, who retains all investment risk.

AFG’s variable annuity contracts contain a guaranteed minimum death benefit (“GMDB”) to be paid if the policyholder dies before the annuity payout period commences. In periods of declining equity markets, the GMDB may exceed the value of the policyholder’s account. A GMDB liability is established for future excess death benefits using assumptions together with a range of reasonably possible scenarios for investment fund performance that are consistent with DPAC capitalization and amortization assumptions.

Leases   On January 1, 2019, AFG adopted ASU 2016-02, which requires entities that lease assets for terms longer than one year to recognize 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. As permitted under the ASU, AFG adopted the guidance on a modified retrospective basis (comparative periods were not adjusted) and elected the following accounting policies and practical expedients:

• exclude leases with a term of 12 months or less from the calculation of lease assets and liabilities,

• not separate lease and non-lease components except for buildings (office space and storage facilities),

• for contracts existing at the date of adoption – not reassess whether a contract is a lease or contains a lease, how initial direct costs were accounted for or whether the lease is an operating or finance lease, and

• use hindsight to determine the lease term for leases existing at the date of adoption.

Adoption of the new guidance resulted in AFG recognizing a lease liability of $198 million (included in other liabilities) and a corresponding right-of-use asset of $174 million (included in other assets and presented net of $24 million in deferred rent and lease incentives) on January 1, 2019. Deferred rent and lease incentives were recognized as liabilities under the previous guidance and result from the straight-line expensing of operating leases. The adoption of the new guidance did not have a material effect on the AFG’s results of operations or liquidity. See Note K — “Leases” for additional disclosures.

Noncontrolling Interests   For balance sheet purposes, noncontrolling interests represent the interests of shareholders other than AFG in consolidated entities. In the statement of earnings, net earnings and losses attributable to noncontrolling interests represents such shareholders’ interest in the earnings and losses of those entities. Noncontrolling

interests that are redeemable at the option of the holder are presented separately in the mezzanine section of the balance sheet (between liabilities and equity).

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. For traditional life, accident and health products, premiums are recognized as revenue when legally collectible from policyholders. For interest-sensitive life and universal life products, premiums are recorded in a policyholder account, which is reflected as a liability. Revenue is recognized as amounts are assessed against the policyholder account for mortality coverage and contract expenses.

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.

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.

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. This includes the impact on deferred tax assets or liabilities established through AOCI, which results in an amount equal to the difference between the deferred tax at the historical corporate rate and the newly enacted rate stranded in AOCI. As permitted under guidance adopted effective December 31, 2017 (ASU 2018-02), AFG reclassified the $145 million stranded in AOCI from accounting for the Tax Cuts and Jobs Act of 2017 to retained earnings at December 31, 2017. See Note M — “Income Taxes” for further information.

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 uses the Black-Scholes pricing model to measure the fair value of employee stock options.

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: 2019 – 1.1 million, 2018 – 1.6 million and 2017 – 2.0 million.

There were no anti-dilutive potential common shares related to stock compensation plans or adjustments to net earnings attributable to shareholders in the calculation of diluted earnings per share for the years ended December 31, 2019, 2018 or 2017.

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. Annuity receipts, surrenders, benefits and withdrawals are also reflected as financing activities. 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.

Credit Impairment Guidance Effective in 2020 In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments, which provides a new loss model for determining credit-related impairments for financial instruments measured at amortized cost (mortgage loans, premiums receivable and reinsurance recoverables) and requires an entity to estimate the 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, will be 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. The updated guidance also amends the current other-than-temporary impairment model for available for sale debt securities by requiring the recognition of impairments relating to credit losses through an allowance account and limits the amount of credit loss to the difference between a security’s amortized cost basis and its fair value. Subsequent increases or decreases in expected credit losses will be recorded immediately in net earnings through realized gains (losses). AFG will adopt this guidance effective January 1, 2020. The new guidance is not expected to have a material impact on AFG’s results of operations or financial position.

Derivatives

As discussed under “Derivatives” in Note A — “Accounting Policies,” AFG uses derivatives in certain areas of its operations.

Derivatives That Do Not Qualify for Hedge Accounting   The following derivatives that do not qualify for hedge accounting under GAAP are included in AFG’s Balance Sheet at fair value (in millions):

		December 31, 2019				December 31, 2018
Derivative	Balance Sheet Line	Asset		Liability		Asset		Liability
MBS with embedded derivatives	Fixed maturities	$	102	$	—	$	109	$	—
Public company warrants	Equity securities	—		—		—		—

Equity index put options	Other liabilities	—		1		—		1
Reinsurance contract (embedded derivative)	Other liabilities	—		4		—		2
		$	1,026	$	3,735	$	293	$	2,723

The MBS with embedded derivatives consist of primarily interest-only and principal-only MBS. AFG records the entire 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.

Warrants to purchase shares of publicly traded companies, which represent a small component of AFG’s overall investment portfolio, are considered to be derivatives that are required to be carried at fair value through earnings.

AFG’s fixed-indexed and variable-indexed annuities provide policyholders with a crediting rate tied, in part, to the performance of an existing stock market or other financial index. AFG attempts to mitigate the risk in the index-based component of these products through the purchase and sale of call and put options on the appropriate index. AFG receives collateral from certain counterparties to support its purchased call option assets (net of collateral required under put option contracts with the same counterparties). This collateral ($577 million at December 31, 2019 and $103 million at December 31, 2018) is included in other assets in AFG’s Balance Sheet with an offsetting liability to return the collateral, which is included in other liabilities. AFG’s strategy is designed so that the net change in the fair value of the call and put options will generally offset the economic change in the net liability from the index participation. Both the index-based component of the annuities (an embedded derivative) and the related call and put options are considered derivatives that must be adjusted for changes in fair value through earnings each period. The fair values of these derivatives are impacted by actual and expected stock market performance and interest rates as well as other factors. Fluctuations in certain of these factors, such as changes in interest rates and the performance of the stock market, are not economic in nature for the current reporting period, but rather impact the timing of reported results.

As discussed under “Reinsurance” in Note A, AFG has a reinsurance contract that is considered to contain an embedded derivative.

The following table summarizes the gains (losses) included in AFG’s Statement of Earnings for changes in the fair value of derivatives that do not qualify for hedge accounting for 2019, 2018 and 2017 (in millions):

Derivative	Statement of Earnings Line	2019			2018			2017
MBS with embedded derivatives	Realized gains (losses) on securities	$	10		$	(7	)	$	(6	)
Public company warrants	Realized gains (losses) on securities	(1		)	(3		)	—
Fixed-indexed and variable-indexed annuities (embedded derivative) (*)	Annuity benefits	(919		)	204			(589		)
Equity index call options	Annuity benefits	804			(298		)	494
Equity index put options	Annuity benefits	2			(1		)	—
Reinsurance contracts (embedded derivative)	Net investment income	(2		)	2			(2		)
		$	(106	)	$	(103	)	$	(103	)

(*) The change in fair value of the embedded derivative includes a favorable adjustment related to unlocking of actuarial assumptions of $181 million in 2019 and losses of $44 million in 2018 and $25 million in 2017.

Derivatives Designated and Qualifying as Cash Flow Hedges   As of December 31, 2019, AFG has thirteen active 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 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 LIBOR.

Under the terms of the swaps, AFG receives fixed-rate interest payments in exchange for variable interest payments based on short-term LIBOR. The notional amounts of the interest rate swaps generally decline over each swap’s respective life (the swaps expire between April 2020 and June 2030) in anticipation of the expected decline in AFG’s portfolio of fixed maturity securities with floating interest rates based on short-term LIBOR. The total outstanding notional amount of AFG’s interest rate swaps was $1.98 billion at December 31, 2019 compared to $2.35 billion at December 31, 2018, reflecting the scheduled amortization discussed above, the termination of two swaps with notional amounts of $138 million and $100 million (on the settlement dates) in the second quarter and fourth quarter of 2019, respectively, and the expiration of a swap with a notional amount of $78 million (on the expiration date) in the third quarter of 2019. The fair value of the interest rate swaps in an asset position and included in other assets was $50 million at December 31, 2019 and $16 million at December 31, 2018. The fair value of the interest rate swaps in a liability position and included in other liabilities was $5 million at December 31, 2019 and $46 million at December 31, 2018. The net unrealized gain or loss on cash flow hedges is included in AOCI, net of DPAC and deferred taxes. Amounts reclassified from AOCI (before DPAC and taxes) to net investment income were income of $3 million in 2019, losses of $3 million in 2018 and income of $6 million in 2017. A collateral receivable supporting these swaps of $20 million at December 31, 2019 and $135 million at December 31, 2018 is included in other assets in AFG’s Balance Sheet.

Acquisitions and Sale of Businesses

Acquisitions and Sale of Businesses

Atlas Financial Holdings, Inc.   In June 2019, National Interstate, a property and casualty insurance subsidiary of AFG, entered into an agreement with Atlas Financial Holdings, Inc. (“AFH”) to become the exclusive underwriter of AFH’s paratransit book of business. National Interstate estimates that the majority of AFH’s $110 million paratransit business will be eligible for quotation under this arrangement over the first 12 months following inception of the agreement. Under the terms of the agreement, AFH will act as an underwriting manager for National Interstate for at least 12 months, after which time National Interstate is entitled to acquire the renewal rights for the business from AFH for a purchase price equal to 15% of the in force gross written premiums at that date. The majority of the purchase price ultimately paid for the renewal rights will be recorded as an intangible renewal rights asset and will be amortized over the estimated life of the business acquired. In connection with the transaction, AFG was granted a five-year warrant to acquire approximately 2.4 million shares of AFH (19.9% at the acquisition date). The estimated fair value of the warrant was approximately $1 million at the date it was received.

ABA Insurance Services Inc.   In November 2018, AFG acquired ABA Insurance Services Inc. (“ABAIS”) from American Bankers Mutual Insurance, Ltd. for approximately $30 million using cash on hand at the parent company. Additional contingent consideration of up to $3 million could be due four years after the acquisition date based on achieving certain operating milestones. ABAIS is based in Ohio and is a market-leading provider of directors and officers liability and other complementary insurance solutions for banks, small businesses and nonprofit organizations.

The allocation of the purchase price is shown in the table below (in millions):

	November 30, 2018
Total purchase price	$	30
Tangible assets acquired	28
Liabilities acquired	26
Net tangible assets acquired, at fair value	2
Excess purchase price over net tangible assets acquired	$	28
Allocation of excess purchase price:
Intangible assets acquired (*)	$	25
Deferred tax on intangible assets acquired (*)	(5		)
Goodwill	8
	$	28

(*) Included in Other assets in AFG’s Balance Sheet.

Approximately $25 million of the purchase price was recorded as a finite lived customer relationship intangible asset, which will be amortized over its estimated life of 9 years. The fair value of this intangible was estimated using a multi-period excess earnings method, which is a form of the income approach. The acquisition resulted in the recognition of $8 million in goodwill based on the excess of the purchase price over the fair value of the net assets acquired. The goodwill represents the fair value of acquired intangible assets that do not qualify for separate recognition, including the value of ABAIS’s assembled workforce. Business generated by ABAIS is included in the Specialty casualty sub-segment.

Neon Lloyd’s Business   In December 2017, AFG completed the sale of an indirect noncontrolling interest in Neon, its United Kingdom-based Lloyd’s insurer, to certain Neon executives for cash equal to the fair value of the interest sold as determined by a third-party valuation firm. Because AFG continues to have a controlling interest in Neon, the sale was accounted for as an equity transaction with the excess of the carrying value of the net assets attributable to the noncontrolling interest sold over the consideration received recorded as a $3 million reduction in AFG’s Capital Surplus. As discussed in Note M — “Income Taxes,” the sale of the noncontrolling interest also resulted in the recognition of a $56 million tax benefit, including a $48 million tax benefit previously deferred in the 2016 restructuring of the Neon Lloyd’s operations.

Contingencies

Contingencies

Establishing property and casualty insurance reserves for claims related to environmental exposures, asbestos and other mass tort claims is subject to uncertainties that are significantly greater than those presented by other types of claims. For this group of claims, traditional actuarial techniques that rely on historical loss development trends cannot be used and a range of reasonably possible losses cannot be estimated. In addition, accruals (included in other liabilities) have been recorded for various environmental and occupational injury and disease claims and other contingencies arising out of the railroad operations disposed of by American Premier’s predecessor, Penn Central Transportation Company (“PCTC”) and its subsidiaries, prior to its bankruptcy reorganization in 1978 and certain manufacturing operations disposed of by American Premier and Great American Financial Resources, Inc. (“GAFRI”).

AFG completed an in-depth internal review of its asbestos and environmental (“A&E”) exposures in the third quarter of 2019. The review resulted in special A&E charges of $18 million for the property and casualty group and $11 million for the former railroad and manufacturing operations. AFG also completed an in-depth internal review of its A&E exposures in the third quarter of 2018, which resulted in special A&E charges of $18 million for the property and casualty group and $9 million for the former railroad and manufacturing operations. AFG completed a comprehensive external study of its A&E exposures in the third quarter of 2017 with the aid of specialty actuarial, engineering and consulting firms and outside counsel. The study resulted in special A&E charges of $89 million for the property and casualty group and $24 million for the former railroad and manufacturing operations.

The property and casualty group’s liability for A&E reserves was $529 million at December 31, 2019; related recoverables from reinsurers (net of allowances for doubtful accounts) at that date were $146 million.

At December 31, 2019, American Premier and its subsidiaries had liabilities for environmental and personal injury claims and other contingencies aggregating $84 million. The environmental claims consist of a number of proceedings and claims seeking to impose responsibility for hazardous waste remediation costs related to certain sites formerly owned or operated by the railroad and manufacturing operations. Remediation costs are difficult to estimate for a number of reasons, including the number and financial resources of other potentially responsible parties, the range of costs for remediation alternatives, changing technology and the time period over which these matters develop. The personal injury claims and other contingencies include pending and expected claims, primarily by former employees of PCTC, for injury or disease allegedly caused by exposure to excessive noise, asbestos or other substances in the workplace and other labor disputes.

At December 31, 2019, GAFRI had a liability of $8 million for environmental costs and certain other matters associated with the sales of its former manufacturing operations.

In December 2015, AFG completed the sale of substantially all of its run-off long-term care insurance business to HC2 Holdings, Inc. (“HC2”). In connection with obtaining regulatory approval for the transaction, AFG agreed to provide up to an aggregate of $35 million of capital support for the insurance companies, on an as-needed basis to maintain specified surplus levels, subject to immediate reimbursement by HC2 through a five-year capital maintenance agreement expiring in 2020.

While management believes AFG has recorded adequate reserves for the items discussed above, the outcome is uncertain and could result in liabilities that may vary from amounts AFG has currently recorded. Such amounts could have a material effect on AFG’s future results of operations and financial condition.

In addition, AFG and its subsidiaries are involved in litigation from time to time, generally arising in the ordinary course of business. This litigation may include, but is not limited to, general commercial disputes, lawsuits brought by policyholders, employment matters, reinsurance collection matters and actions challenging certain business practices of insurance subsidiaries. None of these matters are expected to have a material adverse impact on AFG’s results of operations or financial condition.

Quarterly Operating Results (Unaudited)

Quarterly Financial Information Disclosure [Abstract]

Quarterly Operating Results (Unaudited)

Quarterly Operating Results (Unaudited)

The operations of certain AFG business segments are seasonal in nature. While insurance premiums are recognized on a relatively level basis, claim losses related to adverse weather (snow, hail, hurricanes, severe storms, tornadoes, etc.) may be seasonal. The profitability of AFG’s crop insurance business is primarily recognized during the second half of the year as crop prices and yields are determined. Quarterly results necessarily rely heavily on estimates. These estimates and certain other factors, such as the discretionary sales of assets, cause the quarterly results not to be necessarily indicative of results for longer periods of time.

The following are quarterly results of consolidated operations for the two years ended December 31, 2019 (in millions, except per share amounts). Quarterly earnings per share do not add to year-to-date amounts due to changes in shares outstanding.

	1st Quarter		2nd Quarter		3rd Quarter		4th Quarter			Total Year
2019
Revenues	$	2,024	$	1,960	$	2,123	$	2,130		$	8,237
Net earnings, including noncontrolling interests	326		209		143		191			869
Net earnings attributable to shareholders	329		210		147		211			897

Basic	88.6		89.0		89.1		89.3			89.0
Diluted	90.4		90.7		90.7		89.3			90.6

Pretax realized gains (losses) on securities, which resulted primarily from changes in the fair value of equity securities, were as follows (in millions):

	1st Quarter			2nd Quarter		3rd Quarter			4th Quarter			Total Year
2019 — change in fair value of equity securities	$	182		$	44	$	(15	)	$	67		$	278
2019 — other realized gains (losses)	2			12		(3		)	(2		)	9
2018 — change in fair value of equity securities	(95		)	23		33			(223		)	(262		)
2018 — other realized gains (losses)	2			8		1			(15		)	(4		)

FIAs provide policyholders with a crediting rate tied, in part, to the performance of an existing stock market or other financial index. AFG attempts to mitigate the risk in the index-based component of these products through the purchase and sale of call and put options on the appropriate index. AFG’s strategy is designed so that the change in the fair value of the call and put options will generally offset the economic change in the liabilities from the index participation. Both the index-based component of the annuities and the related call and put options are considered derivatives that must be

marked-to-market through earnings each period. Fluctuations in interest rates and the stock market, among other factors, can cause volatility in the periodic measurement of these derivatives and other FIA liabilities over or under the cost of the equity index options purchased to mitigate the risk in the index-based component of those FIAs.

The impact of unlocking, changes in the fair value of derivatives related to FIAs, and other impacts of changes in the stock market and interest rates on the accounting for FIAs over or under the cost of the equity index options purchased to mitigate the risk in the index-based component of those FIAs were as follows, net of the related acceleration/deceleration of the amortization of deferred policy acquisition costs and deferred sales inducements (in millions):

	1st Quarter			2nd Quarter			3rd Quarter			4th Quarter			Total Year
2019	$	(11	)	$	(33	)	$	(27	)	$	24		$	(47	)
2018	15			(14		)	17			(66		)	(48		)

Favorable prior year development of AFG’s liability for property and casualty losses and loss adjustment expenses (”LAE”) was as follows (in millions):

	1st Quarter		2nd Quarter		3rd Quarter		4th Quarter		Total Year
2019	$	45	$	41	$	12	$	45	$	143
2018	56		44		31		61		192

Prior year development in both the third quarters of 2019 and 2018 includes pretax special charges of $18 million to strengthen property and casualty insurance A&E reserves.

In the fourth quarter of 2019, AFG recorded a pretax charge of $76 million for reserve strengthening and expenses related to exit costs incurred with AFG’s plans to exit the Lloyd’s of London insurance market in 2020.

AFG’s property and casualty operations recorded catastrophe losses, including reinstatement premiums, as follows (in millions):

	1st Quarter			2nd Quarter			3rd Quarter			4th Quarter			Total Year
2019	$	(12	)	$	(12	)	$	(22	)	$	(15	)	$	(61	)
2018	(13		)	(16		)	(38		)	(38		)	(105		)

Results for the third quarter of 2019 and 2018 include pretax special charges of $11 million and $9 million, respectively, to strengthen reserves for A&E exposures related to AFG’s former railroad and manufacturing operations.

AFG recorded a pretax loss on the retirement of debt of $5 million in the fourth quarter of 2019.

Holding company expenses were $20 million higher in the fourth quarter of 2019 compared to the fourth quarter of 2018 due primarily to higher expenses related to employee benefit plans that are tied to stock market performance.

Short-duration insurance contracts, claims development

The following claims development tables and associated disclosures related to short-duration insurance contracts are prepared by sub-segment within the property and casualty insurance business for the most recent 10 accident years. AFG determines its claim counts at the claimant or policy feature level depending on the particular facts and circumstances of the underlying claim. While the methodology is generally consistent within each sub-segment, there are minor differences between and within the sub-segments. The methods used to summarize claim counts have not changed significantly over the time periods reported in the tables below.

Segment Reporting [Abstract]

Segments of Operations

Segments of Operations

AFG manages its business as three segments: (i) Property and casualty insurance, (ii) Annuity and (iii) Other, which includes holding company assets and costs, revenues and costs of AFG’s limited insurance operations outside of property and casualty insurance and annuity segments, 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, 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 deferred gains on retroactive reinsurance transactions related to the sales of businesses in prior years. AFG’s annuity business sells traditional fixed and indexed annuities in the retail, financial institutions, broker-dealer and registered investment advisor markets. AFG’s reportable segments and their components were determined based primarily upon similar economic characteristics, products and services.

Sales of property and casualty insurance outside of the United States represented 7% of AFG’s revenues in 2019 and in 2018 and 5% of AFG’s revenues in 2017. Approximately two-thirds of these 2019 sales were through the Neon Lloyd’s of London business, which AFG is exiting and will no longer write property and casualty business (beginning in early 2020).

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

Leases [Abstract]

Leases

AFG and its subsidiaries lease real estate that is primarily used for office space and, to a lesser extent, equipment under operating lease arrangements. Most of AFG’s real estate leases include an option to extend or renew the lease term at AFG’s option. The operating lease liability includes lease payments related to options to extend or renew the lease term if AFG is reasonably certain of exercising those options. Lease payments are discounted using the implicit discount rate in the lease. If the implicit discount rate for the lease cannot be readily determined, AFG uses an estimate of its incremental secured borrowing rate. AFG did not have any material contracts accounted for as finance leases at December 31, 2019 or January 1, 2019.

At December 31, 2019, AFG’s $158 million operating lease right-of-use asset (presented net of $22 million in deferred rent and lease incentives) and $180 million operating lease liability are included in other assets and other liabilities, respectively, in AFG’s Balance Sheet.

Additional Information

Allowance for Uncollectible Reinsurance   AFG’s aggregate allowance for uncollectible reinsurance recoverables was $18 million at both December 31, 2019 and December 31, 2018. AFG reviews the allowance quarterly and adjusts it as necessary to reflect changes in estimates of uncollectible balances. AFG recorded net expense reductions against the allowance of less than $1 million in 2019, $2 million in 2018 and less than $1 million in 2017. In 2017, the allowance was reduced by reinsurance recoverable write-offs of $2 million.

See Note A — “Accounting Policies — Credit Impairment Guidance Effective in 2020” for a discussion of accounting guidance adopted on January 1, 2020, which provides a new credit loss model for determining credit-related impairments for reinsurance recoverables and requires an entity to estimate the credit losses expected over the life of an exposure or pool of exposures. The new guidance is not expected to have a material impact on AFG’s results of operations or financial position.

Financial Instruments — Unfunded Commitments   On occasion, AFG and its subsidiaries have entered into financial instrument transactions that may present off-balance-sheet risks of both a credit and market risk nature. These transactions include commitments to fund loans, loan guarantees and commitments to purchase and sell securities or loans. At December 31, 2019, AFG and its subsidiaries had commitments to fund credit facilities and contribute capital to limited partnerships and limited liability corporations of approximately $897 million.

Benefit Plans   AFG expensed approximately $39 million in 2019, $37 million in 2018 and $45 million in 2017 for its retirement and employee savings plans.

Income Taxes

The following is a reconciliation of income taxes at the statutory rate (21% in 2019 and 2018 and 35% in 2017) to the provision for income taxes as shown in AFG’s Statement of Earnings (dollars in millions):

In January 2008, AFG paid $75 million in cash to acquire approximately 67% of Neon Underwriting Limited (“Neon”, formerly known as Marketform Group Limited), a United Kingdom-based Lloyd’s insurer. During 2012, AFG acquired the then-remaining shares of Neon that it did not already own for $17 million. AFG’s investment in Neon includes the cost of acquiring the company as well as additional capital provided to Neon since the date of acquisition.

In 2011, cumulative losses at Neon across multiple lines of business resulted in uncertainty concerning the realization of the deferred tax benefits associated with the losses. Consequently, AFG began maintaining a full valuation allowance against the deferred tax assets related to the Lloyd’s insurance business in 2011.

Approximately $14 million of the $21 million impact of “foreign operations” for 2017 in the table above relates to a reduction in the “foreign underwriting losses” deferred tax asset as a result of the sale of the noncontrolling interest in Neon. Since AFG maintains a full valuation allowance against the deferred tax assets related to Neon, this reduction in deferred tax assets was offset by a corresponding reduction in the valuation allowance and had no overall impact on AFG’s income tax expense or results of operations.

The changes in valuation allowance in the table above are primarily increases in the valuation allowance on tax benefits related to losses in the Neon Lloyd’s insurance business. The $61 million decrease in the valuation allowance in 2017 related to the change in the U.S. corporate tax rate is included in “Change in U.S. corporate tax rate” in table above.

The sale of the noncontrolling interest in Neon in the fourth quarter of 2017 resulted in the recognition of a tax benefit of $56 million, including the recognition of a deferred loss from the 2016 restructuring of Neon. Approximately $20 million of the $56 million tax benefit recorded in 2017 reduced current taxes payable for 2017. The majority of the remaining 2017

tax benefit is expected to be received in 2020 as a result of the filing of a refund claim in 2018 to carry back tax basis capital losses to offset prior year tax basis capital gains.

The Tax Cuts and Jobs Act of 2017 (“TCJA”), which was enacted on December 22, 2017, lowered the U.S corporate tax rate to 21% and made other widespread changes to the U.S. tax code effective in 2018. Because the TCJA was enacted in December 2017, AFG recorded the $83 million decrease in its net deferred tax asset resulting from the changes in the tax code (primarily the lower corporate tax rate applicable to 2018 and future years) in the fourth quarter of 2017.

In addition to the lower U.S. corporate tax rate, the TCJA implemented a new global minimum tax on income earned by foreign subsidiaries of U.S.-based entities known as the Global Intangible Low-taxed Income (“GILTI”) provision. Since almost all of AFG’s earnings are taxable based on U.S. tax rates, the GILTI is not expected to be material to AFG’s results of operations and will be recorded in the period that any tax arises.

At the time it was enacted, the TCJA was subject to further clarification and interpretation by the U.S. Treasury Department and the Internal Revenue Service. AFG’s deferred tax assets and liabilities were recorded at December 31, 2017 using reasonable estimates based on available information and were considered provisional in accordance with Securities and Exchange Commission Staff Accounting Bulletin No. 118 (“SAB 118”). In accordance with SAB 118, changes in deferred taxes resulting from clarification and interpretation of the TCJA were recorded in 2018 in the period in which the guidance was published and did not have a material impact on AFG’s effective tax rate. As a result, AFG’s implementation of the TCJA was complete as of December 31, 2018.

Excluding the tax benefit related to the Neon restructuring and the impact of the change in the U.S. corporate tax rate, AFG’s effective tax rate for the year ended December 31, 2017 was 31%.

AFG’s 2013 — 2019 tax years remain subject to examination by the IRS.

Total earnings before income taxes include losses subject to tax in foreign jurisdictions of $109 million in 2019, $69 million in 2018 and $58 million in 2017, primarily related to the Neon Lloyd’s operations.

The total income tax provision (credit) consists of (in millions):

Deferred income tax assets and liabilities reflect temporary differences between the carrying amounts of assets and liabilities recognized for financial reporting purposes and the amounts recognized for tax purposes. The significant components of deferred tax assets and liabilities included in AFG’s Balance Sheet at December 31 were as follows (in millions):

AFG’s net deferred tax asset at December 31, 2019 and 2018 is included in other assets in AFG’s Balance Sheet. The decrease in AFG’s net deferred tax asset at December 31, 2019 compared to December 31, 2018 reflects significantly higher pretax unrealized gains on securities.

The likelihood of realizing deferred tax assets is reviewed periodically; any adjustments required to the valuation allowance are made in the period during which developments requiring an adjustment become known.

“Foreign underwriting losses” in the table above is primarily the net operating loss carryforward and other deferred tax assets related to the Neon Lloyd’s insurance business. Due to uncertainty concerning the realization of the deferred tax benefits associated with these losses, AFG maintains a full valuation allowance of $118 million against these deferred tax assets at December 31, 2019. In addition to the valuation allowance related to the Neon Lloyd’s insurance business, the gross deferred tax asset has also been reduced by a $19 million valuation allowance related to AFG’s net operating loss carryforwards (“NOL”) subject to the separate return limitation year (“SRLY”) tax rules. A SRLY NOL can be used only by the entity that created it and only in years that both it and the consolidated group have taxable income. Approximately $19 million of AFG’s SRLY NOLs expired unutilized at December 31, 2019. Since AFG maintains a full valuation allowance against its SRLY NOLs, the expiration of these loss carryforwards was offset by corresponding reduction in the valuation allowance and had no overall impact on AFG’s income tax expense or results of operations.

AFG increased its liability for uncertain tax positions by $1 million in 2015 due to uncertainty in state taxation of its surplus lines insurance subsidiaries. In 2017, this uncertainty was resolved, resulting in total tax payments of less than $1 million.

A progression of the liability for uncertain tax positions, excluding interest and penalties, follows (in millions):

	2019		2018		2017

Reductions for tax positions of prior years	—		—		—
Additions for tax positions of current year	—		—		—
Settlements	—		—		(1		)
Balance at December 31	$	—	$	—	$	—

At December 31, 2019, there are no unrecognized tax benefits and related interest and penalties that, if recognized, would impact the effective tax rate. The total unrecognized tax benefits and related interest and penalties that, if recognized, would impact the effective tax rate was less than $1 million at December 31, 2018. There is no interest expense related to unrecognized tax benefits included in AFG’s provision for income taxes in 2019; AFG’s provision for income taxes in 2018 and 2017 included interest expense related to unrecognized tax benefits of less than $1 million in each year (net of federal benefit or expense). There is no liability for interest related to unrecognized tax benefits at December 31, 2019 or December 31, 2018. AFG’s provision for income taxes in 2019, 2018 and 2017 included penalties of less than $1 million in each year. There is no liability for penalties related to unrecognized tax benefits at December 31, 2019; AFG’s liability for penalties related to unrecognized tax benefits was less than $1 million at December 31, 2018.

Cash payments for income taxes, net of refunds, were $278 million, $156 million and $194 million for 2019, 2018 and 2017, respectively.

Goodwill and Other Intangibles

Goodwill and Other Intangibles

Changes in the carrying value of goodwill during 2017, 2018 and 2019, by reporting segment, are presented in the following table (in millions):

	Property and Casualty		Annuity		Total
Balance at January 1, 2017 and December 31, 2017	$	168	$	31	$	199
Acquisition of subsidiary in 2018	8		—		8
Balance at December 31, 2018 and December 31, 2019	$	176	$	31	$	207

Goodwill increased by $8 million in the fourth quarter of 2018 due to the purchase of ABAIS as discussed in Note B — “Acquisitions and Sale of Businesses.”

Included in other assets in AFG’s Balance Sheet is $43 million at December 31, 2019 and $54 million at December 31, 2018 of amortizable intangible assets related to property and casualty insurance acquisitions. These amounts are net of accumulated amortization of $50 million and $39 million, respectively. The increase in amortizable intangible assets in 2018 relates to the November 2018 acquisition of ABAIS (discussed in Note B — “Acquisitions and Sale of Businesses”) and a renewal rights intangible asset established in connection with the acquisition of a small property and casualty book of business in January 2018. Amortization of intangibles was $11 million in 2019, $9 million in 2018 and $8 million in 2017. Future amortization of intangibles (weighted average amortization period of 4 years) is estimated to be $12 million in 2020, $6 million in 2021, $4 million per year in 2022, 2023 and 2024 and $13 million thereafter.

The non-credit related portion of other-than-temporary impairment charges is included in other comprehensive income. Cumulative non-credit charges taken for securities still owned at December 31, 2019 and December 31, 2018 were $118 million and $140 million, respectively. Gross unrealized gains on such securities at December 31, 2019 and December 31, 2018 were $114 million and $119 million, respectively. Gross unrealized losses on such securities at December 31, 2019 and December 31, 2018 were $1 million and $4 million, respectively. These amounts represent the non-credit other-than-temporary impairment charges recorded in AOCI adjusted for subsequent changes in fair values and relate primarily to residential MBS.

At December 31, 2019, the gross unrealized losses on fixed maturities of $88 million relate to 649 securities. Investment grade securities (as determined by nationally recognized rating agencies) represented approximately 74% of the gross unrealized loss and 93% of the fair value.

The determination of whether unrealized losses are other-than-temporary requires judgment based on subjective as well as objective factors. Factors considered and resources used by management include:

a) whether the unrealized loss is credit-driven or a result of changes in market interest rates,

b) the extent to which fair value is less than cost basis,

c) cash flow projections received from independent sources,

d) historical operating, balance sheet and cash flow data contained in issuer SEC filings and news releases,

e) near-term prospects for improvement in the issuer and/or its industry,

f) third-party research and communications with industry specialists,

g) financial models and forecasts,

h) the continuity of interest payments, maintenance of investment grade ratings and hybrid nature of certain investments,

i) discussions with issuer management, and

j) ability and intent to hold the investment for a period of time sufficient to allow for anticipated recovery in fair value.

AFG analyzes its MBS securities for other-than-temporary 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. During 2019, 2018 and 2017, AFG recorded other-than-temporary impairment charges related to its residential MBS of $1 million, $6 million and $1 million, respectively.

In 2019, AFG recorded other-than-temporary impairment charges of $17 million on third-party collateralized loan obligations and $11 million on corporate bonds. Other-than-temporary impairment charges on fixed maturities other than residential MBS were $20 million in 2018 and $19 million in 2017. In addition, AFG recorded $4 million in other-than-temporary impairment charges in 2017 on investments that are included in other investments on the balance sheet.

Management believes AFG will recover its cost basis 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 December 31, 2019.

As discussed in Note A — “Accounting Policies — Investments,” effective January 1, 2018, all equity securities previously classified as “available for sale” are required to be carried at fair value through net earnings instead of accumulated other comprehensive income and therefore are no longer evaluated for other-than-temporary impairment. In 2017, AFG recorded other-than-temporary impairment charges on equity securities classified as available for sale of $64 million.

A progression of the credit portion of other-than-temporary impairments on fixed maturity securities for which the non-credit portion of an impairment has been recognized in other comprehensive income is shown below (in millions):

	2019			2018			2017
Balance at January 1	$	142		$	145		$	153
Additional credit impairments on:
Previously impaired securities	1			1			1
Securities without prior impairments	—			1			3
Reductions due to sales or redemptions	(9		)	(5		)	(12		)
Balance at December 31	$	134		$	142		$	145

The table below sets forth the scheduled maturities of available for sale fixed maturities as of December 31, 2019 (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.

	Amortized		Fair Value
	Cost		Amount		%
Maturity
One year or less	$	1,764	$	1,793	4	%
After one year through five years	10,613		11,044		24	%
After five years through ten years	13,513		14,419		31	%
After ten years	3,539		3,754		8	%
	29,429		31,010		67	%
Collateralized loan obligations and other ABS (average life of approximately 4 years)	11,299		11,408		24	%
MBS (average life of approximately 4-1/2 years)	3,796		4,087		9	%
Total	$	44,524	$	46,505	100	%

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 December 31, 2019 or 2018.

Net Unrealized Gain on Marketable Securities   In addition to adjusting fixed maturity securities classified as “available for sale” to fair value, GAAP requires that deferred policy acquisition costs and certain other balance sheet amounts related to annuity, long-term care and life businesses be adjusted to the extent that unrealized gains and losses from securities would result in adjustments to those balances had the unrealized gains or losses actually been realized. The following table shows (in millions) the components of the net unrealized gain on securities that is included in AOCI in AFG’s Balance Sheet.

(*) Although the change in the fair value of the majority of AFG’s equity securities is recorded in realized gains (losses) on securities, AFG records holding gains and losses in net investment income on equity securities classified as “trading” under previous guidance and on a small portfolio of limited partnership and similar investments that do not qualify for the equity method of accounting.

Upon formation between 2012 and 2018, 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 $165 million (including $102 million invested in the most subordinate tranches) at December 31, 2019, and $188 million at December 31, 2018.

During 2019, AFG subsidiaries received less than $1 million in redemption proceeds from their CLO investments. In 2018, AFG formed a new CLO, which issued $463 million face amount of liabilities (including $31 million face amount purchased by subsidiaries of AFG). During 2018, AFG subsidiaries also purchased $7 million face amount of a senior debt tranche of an existing CLO for $7 million and received $45 million in sale and redemption proceeds from its CLO investments. In 2017, AFG formed two new CLOs, which issued an aggregate of $865 million face amount of liabilities (including $48 million face amount purchased by subsidiaries of AFG). During 2017, AFG subsidiaries also purchased $71 million face amount of senior debt and subordinate tranches of existing CLOs for $71 million and received $103 million in sale and redemption proceeds from its CLO investments. In 2018 and 2017, one and two AFG CLOs, respectively, were substantially liquidated, as permitted by the CLO indentures.

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 shareholders of 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):

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

(b) Included in earnings before income taxes 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 $146 million and $232 million at December 31, 2019 and 2018, respectively. The aggregate unpaid principal balance of the CLOs’ debt exceeded its carrying value by $129 million and $241 million at those dates. The CLO assets include loans with an aggregate fair value of $10 million at December 31, 2019, for which the CLOs are not accruing interest because the loans are in default (aggregate unpaid principal balance of $25 million; none at December 31, 2018).

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 carrying value of $4.28 billion at both December 31, 2019 and December 31, 2018.

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 separate account assets, corporate and municipal fixed maturity securities, asset-backed securities (“ABS”), mortgage-backed securities (“MBS”), certain non-affiliated common stocks, equity index options 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.

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 analysts 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, the Company 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.

Assets and liabilities measured and carried at fair value in the financial statements are summarized below (in millions):

The transfers between Level 1 and Level 2 for the years ended December 31, 2019, 2018 and 2017 are reflected in the table below at fair value as of the end of the reporting period (dollars in millions):

	Level 2 To Level 1 Transfers									Level 1 To Level 2 Transfers
	# of Transfers			Fair Value						# of Transfers			Fair Value
	2019	2018	2017	2019		2018		2017		2019	2018	2017	2019		2018		2017

Common stocks	1	—	—	—		—		—		—	—	1	—		—		—

Transfers between Level 1 and Level 2 for all periods presented were a result of increases or decreases in observable trade activity.

Approximately 7% of the total assets carried at fair value on December 31, 2019, were Level 3 assets. Approximately 57% ($2.17 billion) of the 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.

Internally developed Level 3 asset fair values represent approximately $1.36 billion at December 31, 2019. Of this amount, approximately $716 million relates to fixed maturity securities that were priced using management’s best estimate of an appropriate credit spread over the treasury yield (of a similar duration) to discount future expected cash flows using a third-party model. The credit spread applied by management is the significant unobservable input. For this group of approximately 35 securities, the average spread used was 396 basis points over the reference treasury yield and the spreads ranged from 100 basis points to 1,253 basis points (approximately 70% of the spreads were between 200 and 700 basis points). Had management used higher spreads, the fair value of this group of securities would have been lower. Conversely, if the spreads used were lower, the fair values would have been higher. For the remainder of the internally developed prices, any justifiable changes in unobservable inputs used to determine fair value would not have resulted in a material change in AFG’s financial position.

The derivatives embedded in AFG’s fixed-indexed and variable-indexed annuity liabilities are measured using a discounted cash flow approach and had a fair value of $3.73 billion at December 31, 2019. The following table presents information about the unobservable inputs used by management in determining fair value of these Level 3 liabilities. See Note F — “Derivatives.”

Unobservable Input	Range
Adjustment for insurance subsidiary’s credit risk	0.2% – 2.4% over the risk-free rate
Risk margin for uncertainty in cash flows	0.80% reduction in the discount rate
Surrenders	3% – 22% of indexed account value
Partial surrenders	2% – 9% of indexed account value
Annuitizations	0.1% – 1% of indexed account value
Deaths	1.5% – 10.6% of indexed account value
Budgeted option costs	2.5% – 3.3% of indexed account value

The range of adjustments for insurance subsidiary’s credit risk is based on the Moody’s corporate A2 bond index and reflects credit spread variations across the yield curve. The range of projected surrender rates reflects the specific surrender charges and other features of AFG’s individual fixed-indexed and variable-indexed annuity products with an expected range of 7% to 10% in the majority of future calendar years (3% to 22% over all periods). Increasing the budgeted option cost or risk margin for uncertainty in cash flow assumptions in the table above would increase the fair value of the fixed-indexed and variable-indexed annuity embedded derivatives, while increasing any of the other unobservable inputs in the table above would decrease the fair value of the embedded derivatives.

Changes in balances of Level 3 financial assets and liabilities carried at fair value during 2019, 2018 and 2017 are presented below (in millions). The transfers into and out of Level 3 were due to changes in the availability of market observable inputs and $29 million of equity securities transferred into Level 3 in the first quarter of 2018 related to a small number of limited partnerships and similar investments carried at cost under the prior guidance that are carried at fair value through net earnings under new guidance adopted on January 1, 2018, as discussed in Note A — “Accounting Policies — Investments.” All transfers are reflected in the table at fair value as of the end of the reporting period.

(a)    The reclassification adjustment out of net unrealized gains (losses) on securities affected the following lines in AFG’s Statement of Earnings:

OCI component	Affected line in the statement of earnings
Pretax	Realized gains (losses) on securities
Tax	Provision for income taxes

(b) Includes net unrealized gains of $55 million at December 31, 2019 compared to $58 million and $68 million at December 31, 2018 and 2017, related to securities for which only the credit portion of an other-than-temporary impairment has been recorded in earnings.

(c)

On January 1, 2018, AFG adopted new guidance that requires all equity securities other than those accounted for under the equity method to be reported at fair value with holding gains and losses recognized in net earnings. At the date of adoption, the $221 million net unrealized gain on equity securities classified as available for sale (with unrealized holding gains and losses reported in AOCI) under the prior guidance was reclassified from AOCI to retained earnings as the cumulative effect of an accounting change. Other also includes the December 2017 reclassification of $145 million stranded in AOCI from accounting for the Tax Cuts and Jobs Act of 2017 to retained earnings (see Note A — “Accounting Policies — Income Taxes”) and the impact on AOCI of the December 2017 sale of redeemable noncontrolling interests in Neon.

Insurance

Cash and securities owned by U.S.-based insurance subsidiaries, having a carrying value of approximately $1.04 billion at December 31, 2019, were on deposit as required by regulatory authorities. In addition, $217 million was on deposit in support of AFG’s underwriting activities at Lloyd’s. At December 31, 2019, AFG and its subsidiaries had $414 million in undrawn letters of credit (none of which was collateralized) and similar agreements supporting the underwriting capacity of its U.K.-based Lloyd’s insurer, Neon.

Property and Casualty Insurance Reserves   Estimating the liability for unpaid losses and loss adjustment expenses (“LAE”) is inherently judgmental and is influenced by factors that are subject to significant variation. Determining the liability is a complex process incorporating input from many areas of the Company including actuarial, underwriting, pricing, claims and operations management.

The process used to determine the total reserve for liabilities involves estimating the ultimate incurred losses and LAE, adjusted for amounts already paid on the claims. The IBNR reserve is derived by first estimating the ultimate unpaid reserve liability and subtracting case reserves for loss and LAE.

In determining management’s best estimate of the ultimate liability, management (with the assistance of Company actuaries) considers items such as the effect of inflation on medical, hospitalization, material, repair and replacement costs, the nature and maturity of lines of insurance, general economic trends and the legal environment. In addition, historical trends adjusted for changes in underwriting standards, policy provisions, product mix and other factors are analyzed using actuarial reserve development techniques. Weighing all of the factors, the management team determines a single or “point” estimate that it records as its best estimate of the ultimate liability. Ranges of loss reserves are not developed by Company actuaries. This reserve analysis and review is completed each quarter and for almost every business within AFG’s property and casualty insurance sub-segments.

Each review includes in-depth analysis of several hundred subdivisions of the business, employing multiple actuarial techniques. For each subdivision, actuaries use informed, professional judgment to adjust these techniques as necessary to respond to specific conditions in the data or within the business.

Some of the standard actuarial methods employed for the quarterly reserve analysis may include (but may not be limited to):

• Case Incurred Development Method

• Paid Development Method

• Bornhuetter-Ferguson Method

• Incremental Paid LAE to Paid Loss Methods

Management believes that each method has particular strengths and weaknesses and that no single estimation method is most accurate in all situations. When applied to a particular group of claims, the relative strengths and weaknesses of each method can change over time based on the facts and circumstances. Ultimately, the estimation methods chosen are those which management believes produce the most reliable indication for the particular liabilities under review.

The period of time from the occurrence of a loss through the settlement of the liability is referred to as the “tail”. Generally, the same actuarial methods are considered for both short-tail and long-tail lines of business because most of them work properly for both. The methods are designed to incorporate the effects of the differing length of time to settle particular claims. For short-tail lines, management tends to give more weight to the Case Incurred and Paid Development methods, although the various methods tend to produce similar results. For long-tail lines, more judgment is involved, and more weight may be given to the Bornhuetter-Ferguson method. Liability claims for long-tail lines are more susceptible to litigation and can be significantly affected by changing contract interpretation and the legal environment. Therefore, the estimation of loss reserves for these classes is more complex and subject to a higher degree of variability.

The level of detail in which data is analyzed varies among the different lines of business. Data is generally analyzed by major product or by coverage within product, using countrywide data; however, in some situations, data may be reviewed by state or region. Appropriate segmentation of the data is determined based on data credibility, homogeneity of development patterns, mix of business, and other actuarial considerations.

Supplementary statistical information is also reviewed to determine which methods are most appropriate to use or if adjustments are needed to particular methods. Such information includes:

• Open and closed claim counts

• Average case reserves and average incurred on open claims

• Closure rates and statistics related to closed and open claim percentages

• Average closed claim severity

• Ultimate claim severity

• Reported loss ratios

• Projected ultimate loss ratios

• Loss payment patterns

Within each business, results of individual methods are reviewed, supplementary statistical information is analyzed, and data from underwriting, operating and claim management are considered in deriving management’s best estimate of the ultimate liability. This estimate may be the result of one method, a weighted average of several methods, or a judgmental selection as the management team determines is appropriate.

The liability for losses and LAE for a very limited number of claims with long-term scheduled payments under certain workers’ compensation policies has been discounted at 4.5% at both December 31, 2019 and 2018, which represents an approximation of long-term investment yields. Because of the limited amount of claims involved, the net impact of

discounting did not materially impact AFG’s total liability for unpaid losses and loss adjustment expenses (net reductions from discounting of $12 million and $13 million at December 31, 2019 and 2018, respectively).

The following table provides an analysis of changes in the liability for losses and loss adjustment expenses over the past three years (in millions):

	2019			2018			2017
Balance at beginning of period	$	9,741		$	9,678		$	8,563
Less reinsurance recoverables, net of allowance	2,942			2,957			2,302

(*) Reflects the reinsurance to close transactions at Neon (discussed below).

The net decrease in the provision for claims of prior years in 2019 reflects (i) lower than expected claim frequency and severity at National Interstate and lower than expected losses in the crop business (all within the Property and transportation sub-segment), (ii) lower than anticipated claim frequency and severity in the workers’ compensation businesses (within the Specialty casualty sub-segment), and (iii) lower than expected claim frequency and severity in the surety and financial institutions businesses and lower than anticipated claim severity in the foreign credit business (all within the Specialty financial sub-segment). This favorable development was partially offset by (i) the $18 million special charge to increase asbestos and environmental reserves and adverse reserve development of $7 million on Neon’s exited lines of business, (ii) higher than expected claim severity in the excess and surplus lines businesses and higher than expected claim frequency in product liability contractor claims (all within the Specialty casualty sub-segment), and (iii) net adverse reserve development related to business outside the Specialty group that AFG no longer writes.

The net decrease in the provision for claims of prior years in 2018 reflects (i) lower than expected losses in the crop business and lower than expected claim severity at National Interstate (within the Property and transportation sub-segment), (ii) lower than anticipated claim severity in the workers’ compensation businesses, lower than expected emergence in assumed 2017 property catastrophe losses at Neon and lower than expected claim severity in the executive liability business (within the Specialty casualty sub-segment) and (iii) lower than expected claim frequency and severity in the surety business, lower than expected claim severity in the fidelity business and lower than expected claim frequency in run-off businesses (within the Specialty financial sub-segment). This favorable development was partially offset by (i) the $18 million special charge to increase asbestos and environmental reserves and (ii) higher than expected claim frequency and severity in the Singapore branch and aviation operations (within the Property and transportation sub-segment).

The net decrease in the provision for claims of prior years in 2017 reflects (i) lower than expected losses in the crop and equine businesses and lower than expected claim severity in the property and inland marine and transportation businesses (all within the Property and transportation sub-segment), (ii) favorable reserve development of $18 million on Neon’s exited lines, as well as additional favorable development on ongoing lines of business within Neon, recorded in connection with the reinsurance to close agreement entered into in December 2017 for the 2015 and prior years of account, lower than anticipated claim severity in the workers’ compensation businesses and lower than expected losses in the executive liability business (all within the Specialty casualty sub-segment) and (iii) lower than anticipated claim severity in the fidelity business and lower than expected claim frequency and severity in the surety business (both within the Specialty financial sub-segment). This favorable development was partially offset by (i) the $89 million special charge

to increase asbestos and environmental reserves, (ii) higher than expected claim frequency and severity in the ocean marine business (within the Property and transportation sub-segment), (iii) higher than anticipated claim severity in the targeted markets and general liability businesses and higher than anticipated severity in New York contractor claims (all within the Specialty casualty sub-segment) and (iv) a charge to adjust to the deferred gain on the retroactive reinsurance transaction entered into in connection with the sale of businesses in 1998 (included in Other specialty sub-segment).

In December 2017, the Neon Lloyd’s syndicate entered into a reinsurance to close transaction for the 2015 and prior years of account with StarStone Underwriting Limited, a subsidiary of Enstar Group Limited, which was effective as of December 31, 2017 and settled in early 2018. In the Lloyd’s market, a reinsurance to close transaction transfers the responsibility for discharging all of the liabilities that attach to the transferred year of account plus the right to any income due to the closing year of account in return for a premium. This transaction provided Neon with finality on its legacy business. As a result of the reinsurance to close agreement, Neon was able to better estimate its ultimate liability for the 2015 and prior years of account as of December 31, 2017, resulting in favorable development of $42 million, of which $24 million related to its ongoing lines of business (included in Specialty casualty) and $18 million related to its exited lines of business.

A reconciliation of incurred and paid claims development information to the aggregate carrying amount of the liability for unpaid losses and LAE, with separate disclosure of reinsurance recoverables on unpaid claims is shown below (in millions):

The following claims development tables and associated disclosures related to short-duration insurance contracts are prepared by sub-segment within the property and casualty insurance business for the most recent 10 accident years. AFG determines its claim counts at the claimant or policy feature level depending on the particular facts and circumstances of the underlying claim. While the methodology is generally consistent within each sub-segment, there are minor differences between and within the sub-segments. The methods used to summarize claim counts have not changed significantly over the time periods reported in the tables below.

Closed Block of Long-Term Care Insurance Reserves for AFG’s closed block of long-term care insurance were $46 million at December 31, 2019 and $45 million at December 31, 2018, net of reinsurance recoverables and excluding the impact of unrealized gains on securities. AFG’s remaining outstanding long-term care policies have level premiums and are guaranteed renewable. Premium rates can potentially be increased in reaction to adverse experience; however, any rate increases would require regulatory approval.

FHLB Funding Agreements   Great American Life Insurance Company (“GALIC”), a wholly-owned annuity subsidiary, is a member of the Federal Home Loan Bank of Cincinnati (“FHLB”). The FHLB makes advances and provides other banking services to member institutions. Members are required to purchase stock in the FHLB in addition to maintaining collateral deposits that back any funds advanced. GALIC’s $52 million investment in FHLB capital stock at December 31, 2019 is included in other investments at cost. Membership in the FHLB provides the annuity operations with an additional source of liquidity. These advances further the FHLB’s mission of improving access to housing by increasing liquidity in the residential mortgage-backed securities market.

In 2019, GALIC refinanced the terms on advances totaling $610 million. In the fourth quarter of 2018, GALIC refinanced the terms on a $40 million advance and the FHLB advanced GALIC $225 million. At both December 31, 2019 and December 31, 2018, GALIC had $1.10 billion in outstanding advances from the FHLB (included in annuity benefits accumulated), bearing interest at rates ranging from 0.13% to 0.21% over LIBOR (average rate of 1.95% at December 31, 2019). While these advances must be repaid between 2020 and 2021 ($310 million in 2020 and $786 million in 2021), GALIC has the option to prepay all or a portion of the advances. GALIC has invested the proceeds from the advances in fixed maturity securities with similar expected lives as the advances for the purpose of earning a spread over the interest payments due to the FHLB. The advances on these agreements are collateralized by fixed maturity investments, which have a total fair value of $1.27 billion (included in available for sale fixed maturity securities) at December 31, 2019. Interest credited on the funding agreements, which is included in annuity benefits, was $27 million in 2019, $20 million in 2018 and $14 million in 2017.

Statutory Information   AFG’s U.S.-based insurance subsidiaries are required to file financial statements with state insurance regulatory authorities prepared on an accounting basis prescribed or permitted by such authorities (statutory basis). Net earnings and capital and surplus on a statutory basis for the insurance subsidiaries were as follows (in millions):

	Net Earnings						Capital and Surplus
	2019		2018		2017		2019		2018
Property and casualty companies	$	584	$	546	$	484	$	3,342	$	2,867
Life (annuity) insurance companies	34		802		286		2,868		2,701

In the fourth quarter of 2018, GALIC, AFG’s primary annuity subsidiary, entered into a reinsurance treaty with Hannover Life Reassurance Company of America that transfers the risk of certain surrender activity in GALIC’s fixed-indexed annuity business. This treaty meets the statutory risk transfer rules and resulted in a $510 million increase in statutory surplus (through an after-tax reserve credit), which is reflected in the life insurance companies capital and surplus in the table above. Under GAAP, this transaction does not meet the GAAP insurance risk transfer criteria and did not have a material impact on AFG’s financial statements.

The National Association of Insurance Commissioners’ (“NAIC”) model law for risk-based capital (“RBC”) applies to both life and property and casualty insurance companies. RBC formulas determine the amount of capital that an insurance company needs so that it has an acceptable expectation of not becoming financially impaired. Companies below specific trigger points or ratios are subject to regulatory action. At December 31, 2019 and 2018, the capital ratios of all AFG insurance companies substantially exceeded the RBC requirements. AFG’s insurance companies did not use any prescribed or permitted statutory accounting practices that differed from the NAIC statutory accounting practices at December 31, 2019 or 2018.

Payments of dividends by AFG’s insurance companies are subject to various state laws that limit the amount of dividends that can be paid. Under applicable restrictions, the maximum amount of dividends available to AFG in 2020 from its insurance subsidiaries without seeking regulatory approval is $852 million. Additional amounts of dividends require regulatory approval.

Holding Company Dividends   AFG declared and paid common stock dividends to shareholders totaling $446 million, $397 million and $421 million in 2019, 2018 and 2017, respectively. Currently, there are no regulatory restrictions on AFG’s retained earnings or net earnings that materially impact its ability to pay dividends. Based on shareholders’ equity at December 31, 2019, AFG could pay dividends in excess of $2.5 billion without violating its most restrictive debt covenant. However, the payment of future dividends will be at the discretion of AFG’s Board of Directors and will be dependent on many factors including AFG’s financial condition and results of operations, the capital requirements of its insurance subsidiaries, and rating agency commitments.

Reinsurance   In the normal course of business, AFG’s insurance subsidiaries cede reinsurance to other companies to diversify risk and limit maximum loss arising from large claims. However, AFG remains liable to its insureds regardless of whether a reinsurer is able to meet its obligations. The following table shows (in millions) (i) amounts deducted from property and casualty written and earned premiums in connection with reinsurance ceded, (ii) written and earned premiums included in income for reinsurance assumed and (iii) reinsurance recoveries, which represent ceded losses and loss adjustment expenses.

In June 2017, AFG’s property and casualty insurance subsidiaries entered into a reinsurance agreement to obtain supplemental catastrophe protection through a catastrophe bond structure with Riverfront Re Ltd. (“Riverfront”). The reinsurance agreement provides supplemental reinsurance coverage up to 95% of $200 million (fully collateralized) for catastrophe losses in excess of $134 million of traditional catastrophe reinsurance (per occurrence and annual aggregate) occurring until December 31, 2020. In connection with the reinsurance agreement, Riverfront issued notes to unrelated investors for the full amount of coverage provided under the reinsurance agreement. Through December 31, 2019, AFG’s incurred catastrophe losses have not reached the level of attachment for the catastrophe bond structure. Riverfront is a variable interest entity in which AFG does not have a variable interest because the variability in Riverfront’s results will be absorbed entirely by the investors in Riverfront. Accordingly, Riverfront is not consolidated in AFG’s financial statements and the reinsurance agreement is accounted for as ceded reinsurance. AFG’s cost for this coverage is approximately $11 million per year.

AFG has reinsured approximately $6.23 billion of its $9.53 billion in face amount of life insurance at December 31, 2019 compared to $7.69 billion of its $10.82 billion in face amount of life insurance at December 31, 2018. Life written premiums ceded were $20 million, $22 million and $28 million for 2019, 2018 and 2017, respectively. Reinsurance recoveries on ceded life policies were $32 million, $38 million and $35 million for 2019, 2018 and 2017, respectively.

Fixed Annuities   For certain products, the liability for “annuity benefits accumulated” includes reserves for excess benefits expected to be paid on future deaths and annuitizations guaranteed withdrawal benefits and accrued persistency and premium bonuses. The liabilities included in AFG’s Balance Sheet for these benefits, excluding the impact of unrealized gains on securities, were as follows at December 31 (in millions):

	2019		2018
Expected death and annuitization	$	232	$	229
Guaranteed withdrawal benefits	625		472
Accrued persistency and premium bonuses	1		1

Variable Annuities   At December 31, 2019, the aggregate guaranteed minimum death benefit value (assuming every variable annuity policyholder died on that date) on AFG’s variable annuity policies exceeded the fair value of the underlying variable annuities by $13 million, compared to $35 million at December 31, 2018. Death benefits paid in excess of the variable annuity account balances were less than $1 million in each of the last three years ended December 31, 2019, 2018 and 2017.

The total intrinsic value of options exercised during 2019, 2018 and 2017 was $46 million, $57 million and $65 million, respectively. During 2019, 2018 and 2017, AFG received $31 million, $29 million and $34 million, respectively, in cash from the exercise of stock options. The total tax benefit related to the exercises was $8 million, $9 million and $18 million during those years, respectively.

Total compensation expense related to stock incentive plans of AFG and its subsidiaries was $23 million for 2019 and 2018 and $30 million for 2017. AFG’s provision for income tax includes tax benefits of $13 million in 2019 and 2018 and $27 million in 2017 related to AFG’s stock incentive plans. At December 31, 2019, there was $36 million of unrecognized compensation expense related to restricted stock awards, which is expected to be recognized over a weighted average of 2.4 years. At December 31, 2019, there was less than $1 million of unrecognized compensation expense related to unvested stock options, which will be recognized in the first quarter of 2020.

Accumulated Other Comprehensive Income, 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, which consists primarily of changes in net unrealized gains or losses on available for sale securities. The progression of the components of accumulated other comprehensive income follows (in millions):

(a)    The reclassification adjustment out of net unrealized gains (losses) on securities affected the following lines in AFG’s Statement of Earnings:

OCI component	Affected line in the statement of earnings
Pretax	Realized gains (losses) on securities
Tax	Provision for income taxes

(b) Includes net unrealized gains of $55 million at December 31, 2019 compared to $58 million and $68 million at December 31, 2018 and 2017, related to securities for which only the credit portion of an other-than-temporary impairment has been recorded in earnings.

(c)

On January 1, 2018, AFG adopted new guidance that requires all equity securities other than those accounted for under the equity method to be reported at fair value with holding gains and losses recognized in net earnings. At the date of adoption, the $221 million net unrealized gain on equity securities classified as available for sale (with unrealized holding gains and losses reported in AOCI) under the prior guidance was reclassified from AOCI to retained earnings as the cumulative effect of an accounting change. Other also includes the December 2017 reclassification of $145 million stranded in AOCI from accounting for the Tax Cuts and Jobs Act of 2017 to retained earnings (see Note A — “Accounting Policies — Income Taxes”) and the impact on AOCI of the December 2017 sale of redeemable noncontrolling interests in Neon.

Accounting Policies (Policies)

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation   The consolidated financial statements include the accounts of American Financial Group, Inc. and its subsidiaries (“AFG”). Certain reclassifications have been made to prior years 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 December 31, 2019, and prior to the filing of this Form 10-K, have been evaluated for potential recognition or disclosure herein.

The preparation of the financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) 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.

On January 1, 2018, AFG adopted Accounting Standards Update (“ASU”) 2014-09, which provides guidance on recognizing revenue when (or as) performance obligations under the contract are satisfied. The guidance also updates the accounting for certain costs associated with obtaining and fulfilling contracts with customers and requires certain new disclosures. Because revenue recognition for insurance contracts and financial instruments (AFG’s primary sources of revenue) were excluded from the scope of the new guidance, the adoption of ASU 2014-09 did not have a material impact on AFG’s results of operations or financial position.

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 2019 or 2018.

Investments

Investments   On January 1, 2018, AFG adopted ASU 2016-01, which requires all equity securities other than those accounted for under the equity method to be reported at fair value with holding gains and losses recognized in net earnings. At December 31, 2017, AFG had $1.60 billion in equity securities classified as “available for sale” under the prior guidance with holding gains and losses included in accumulated other comprehensive income (“AOCI”) instead of net earnings. At the date of adoption, the $221 million net unrealized gain on equity securities included in AOCI was reclassified to retained earnings as the cumulative effect of an accounting change. The cumulative effect of the accounting change also includes the net unrealized gain on AFG’s small number of limited partnerships and similar investments carried at cost under the prior guidance that are carried at fair value through net earnings under the new guidance ($4 million net of tax at the date of adoption).

Following the adoption of ASU 2016-01, holding gains and losses on equity securities carried at fair value are generally recorded in realized gains (losses) on securities. However, AFG records holding gains and losses on securities classified as “trading” under previous guidance, its small portfolio of limited partnerships and similar investments carried at fair value and certain other securities classified at purchase as “fair value through net investment income” in net investment income.

Under the new guidance, AFG recorded holding gains of $207 million on equity securities in net earnings during 2019 on securities still held at December 31, 2019 and holding losses of $257 million on equity securities in net earnings during 2018 on securities that were still owned at December 31, 2018. Under the prior guidance, these holding losses would have been recorded in AOCI until the securities were disposed (with exception of any impairment charge that may have been recorded). Because almost all of the equity securities impacted by the new guidance were carried at fair value through AOCI under the prior guidance, the adoption of the new guidance did not have a material impact on AFG’s financial position.

Fixed maturity securities classified as “available for sale” are reported at fair value with unrealized gains and losses included in 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 and policy loans are carried primarily at the aggregate unpaid balance.

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 they are 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.

Gains or losses on fixed maturity securities classified as “available for sale” are determined on the specific identification basis. When a decline in the value of a specific investment is considered to be other-than-temporary at the balance sheet date, a provision for impairment is charged to earnings (included in realized gains (losses) on securities) and the cost basis of that investment is reduced. If management can assert that it does not intend to sell an impaired fixed maturity security and it is not more likely than not that it will have to sell the security before recovery of its amortized cost basis, then the other-than-temporary impairment is separated into two components: (i) the amount 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 of an other-than-temporary impairment 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 impairment charge. Both components are shown in the statement of earnings. 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 charge to earnings is recorded to reduce the amortized cost of that security to fair value.

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. Derivatives that do not qualify for hedge accounting under GAAP consist primarily of (i) components of certain fixed maturity securities (primarily interest-only and principal-only MBS) and (ii) the equity-based component of certain annuity products (included in annuity benefits accumulated) and related equity index options designed to be consistent with the characteristics of the liabilities and used to mitigate the risk embedded in those annuity products.

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 and ineffectiveness will be measured on a retrospective and prospective basis.

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 included in AFG’s portfolio of fixed maturity securities.

Goodwill

Goodwill   Goodwill represents the excess of cost of subsidiaries over AFG’s equity in their underlying net assets. 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’s property and casualty insurance subsidiaries report 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’s property and casualty insurance subsidiaries under contracts to fund ceded losses as they become due. AFG’s insurance subsidiaries also assume reinsurance from other companies. Earnings on reinsurance assumed is recognized based on information received from ceding companies.

An AFG subsidiary cedes life insurance policies to a third-party on a funds withheld basis whereby the subsidiary retains the assets (securities) associated with the reinsurance contract. Interest is credited to the reinsurer based on the actual investment performance of the retained assets. This reinsurance contract is considered to contain an embedded derivative (that must be adjusted to fair value) because the yield on the payable is based on a specific block of the ceding company’s assets, rather than the overall creditworthiness of the ceding company. AFG determined that changes in the fair value of the underlying portfolio of fixed maturity securities is an appropriate measure of the value of the embedded derivative. The securities related to this contract are classified as “trading.” The adjustment to fair value on the embedded derivative offsets the investment income recorded on the adjustment to fair value of the related trading portfolio.

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 also includes capitalized costs associated with sales inducements offered to fixed annuity policyholders such as enhanced interest rates and premium and persistency bonuses.

For the property and casualty companies, 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.

DPAC related to annuities is deferred to the extent deemed recoverable and amortized, with interest, in relation to the present value of actual and expected gross profits on the policies. Expected gross profits consist principally of estimated future investment margin (estimated future net investment income less interest credited on policyholder funds) and surrender, mortality, and other life and annuity policy charges, less death, annuitization and guaranteed withdrawal benefits in excess of account balances and estimated future policy administration expenses. To the extent that realized gains and losses result in adjustments to the amortization of DPAC related to annuities, such adjustments are reflected as components of realized gains (losses) on securities.

DPAC related to traditional life and health insurance is amortized over the expected premium paying period of the related policies, in proportion to the ratio of annual premium revenues to total anticipated premium revenues. See “Life, Accident and Health Reserves” below for details on the impact of loss recognition on the accounting for traditional life and health insurance contracts.

DPAC includes the present value of future profits on business in force of annuity and life, accident and health insurance companies acquired (“PVFP”). PVFP represents the portion of the costs to acquire companies that is allocated to the value of the right to receive future cash flows from insurance contracts existing at the date of acquisition. PVFP is amortized with interest in relation to expected gross profits of the acquired policies for annuities and universal life products and in relation to the premium paying period for traditional life and health insurance products.

DPAC and certain other balance sheet amounts related to annuity and life businesses are also adjusted, net of tax, for the change in expense that would have been recorded if the unrealized gains (losses) from securities had actually been realized. These adjustments are included in unrealized gains (losses) on marketable securities, a component of AOCI in AFG’s Balance Sheet.

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 H — “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.

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.

Annuity Benefits Accumulated

Annuity Benefits Accumulated   Annuity receipts and benefit payments are recorded as increases or decreases in annuity benefits accumulated rather than as revenue and expense. Increases in this liability for interest credited are charged to annuity benefits expense and decreases for annuity policy charges are recorded in other income. For traditional fixed annuities, the liability for annuity benefits accumulated represents the account value that had accrued to the benefit of the policyholder as of the balance sheet date. For fixed-indexed annuities (“FIAs”), the liability for annuity benefits accumulated includes an embedded derivative that represents the estimated fair value of the index participation with the remaining component representing the discounted value of the guaranteed minimum contract benefits.

For certain products, annuity benefits accumulated also includes reserves for accrued persistency and premium bonuses, guaranteed withdrawals and excess benefits expected to be paid on future deaths and annuitizations (“EDAR”). The liabilities for EDAR and guaranteed withdrawals are accrued for and modified using assumptions consistent with those used in determining DPAC and DPAC amortization, except that amounts are determined in relation to the present value of total expected assessments. Total expected assessments consist principally of estimated future investment margin, surrender, mortality, and other life and annuity policy charges, and unearned revenues once they are recognized as income.

Annuity benefits accumulated also includes amounts advanced from the Federal Home Loan Bank of Cincinnati.

Unearned Revenue

Unearned Revenue   Certain upfront policy charges on annuities are deferred as unearned revenue (included in other liabilities) and recognized in net earnings (included in other income) using the same assumptions and estimated gross profits used to amortize DPAC.

Life, Accident and Health Reserves

Life, Accident and Health Reserves   Liabilities for future policy benefits under traditional life, accident and health policies are computed using the net level premium method. Computations are based on the original projections of investment yields, mortality, morbidity and surrenders and include provisions for unfavorable deviations unless a loss recognition event (premium deficiency) occurs. Claim reserves and liabilities established for accident and health claims are modified as necessary to reflect actual experience and developing trends.

For long-duration contracts (such as traditional life and long-term care policies), loss recognition occurs when, based on current expectations as of the measurement date, existing contract liabilities plus the present value of future premiums (including reasonably expected rate increases) are not expected to cover the present value of future claims payments and related settlement and maintenance costs (excluding overhead) as well as unamortized acquisition costs. If a block of business is determined to be in loss recognition, a charge is recorded in earnings in an amount equal to the excess of the present value of expected future claims costs and unamortized acquisition costs over existing reserves plus the present value of expected future premiums (with no provision for adverse deviation). The charge is recorded first to reduce unamortized acquisition costs and then as an additional reserve (if unamortized acquisition costs have been reduced to zero).

In addition, reserves for traditional life and long-term care policies are subject to adjustment for loss recognition charges that would have been recorded if the unrealized gains (losses) from securities had actually been realized. This adjustment is included in unrealized gains (losses) on marketable securities, a component of AOCI in AFG’s Balance Sheet.

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.

Variable Annuity Assets and Liabilities

Variable Annuity Assets and Liabilities   Separate accounts related to variable annuities represent the fair value of deposits invested in underlying investment funds on which AFG earns a fee. Investment funds are selected and may be changed only by the policyholder, who retains all investment risk.

AFG’s variable annuity contracts contain a guaranteed minimum death benefit (“GMDB”) to be paid if the policyholder dies before the annuity payout period commences. In periods of declining equity markets, the GMDB may exceed the value of the policyholder’s account. A GMDB liability is established for future excess death benefits using assumptions together with a range of reasonably possible scenarios for investment fund performance that are consistent with DPAC capitalization and amortization assumptions.

Leases

Leases   On January 1, 2019, AFG adopted ASU 2016-02, which requires entities that lease assets for terms longer than one year to recognize 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. As permitted under the ASU, AFG adopted the guidance on a modified retrospective basis (comparative periods were not adjusted) and elected the following accounting policies and practical expedients:

• exclude leases with a term of 12 months or less from the calculation of lease assets and liabilities,

• not separate lease and non-lease components except for buildings (office space and storage facilities),

• for contracts existing at the date of adoption – not reassess whether a contract is a lease or contains a lease, how initial direct costs were accounted for or whether the lease is an operating or finance lease, and

• use hindsight to determine the lease term for leases existing at the date of adoption.

Adoption of the new guidance resulted in AFG recognizing a lease liability of $198 million (included in other liabilities) and a corresponding right-of-use asset of $174 million (included in other assets and presented net of $24 million in deferred rent and lease incentives) on January 1, 2019. Deferred rent and lease incentives were recognized as liabilities under the previous guidance and result from the straight-line expensing of operating leases. The adoption of the new guidance did not have a material effect on the AFG’s results of operations or liquidity. See Note K — “Leases” for additional disclosures.

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. For traditional life, accident and health products, premiums are recognized as revenue when legally collectible from policyholders. For interest-sensitive life and universal life products, premiums are recorded in a policyholder account, which is reflected as a liability. Revenue is recognized as amounts are assessed against the policyholder account for mortality coverage and contract expenses.

Noncontrolling Interests

Noncontrolling Interests   For balance sheet purposes, noncontrolling interests represent the interests of shareholders other than AFG in consolidated entities. In the statement of earnings, net earnings and losses attributable to noncontrolling interests represents such shareholders’ interest in the earnings and losses of those entities. Noncontrolling

interests that are redeemable at the option of the holder are presented separately in the mezzanine section of the balance sheet (between liabilities and equity).

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.

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.

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. This includes the impact on deferred tax assets or liabilities established through AOCI, which results in an amount equal to the difference between the deferred tax at the historical corporate rate and the newly enacted rate stranded in AOCI. As permitted under guidance adopted effective December 31, 2017 (ASU 2018-02), AFG reclassified the $145 million stranded in AOCI from accounting for the Tax Cuts and Jobs Act of 2017 to retained earnings at December 31, 2017. See Note M — “Income Taxes” for further information.

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 uses the Black-Scholes pricing model to measure the fair value of employee stock options.

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: 2019 – 1.1 million, 2018 – 1.6 million and 2017 – 2.0 million.

There were no anti-dilutive potential common shares related to stock compensation plans or adjustments to net earnings attributable to shareholders in the calculation of diluted earnings per share for the years ended December 31, 2019, 2018 or 2017.

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. Annuity receipts, surrenders, benefits and withdrawals are also reflected as financing activities. 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.

Credit Impairment Guidance Effective in 2020

Credit Impairment Guidance Effective in 2020 In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments, which provides a new loss model for determining credit-related impairments for financial instruments measured at amortized cost (mortgage loans, premiums receivable and reinsurance recoverables) and requires an entity to estimate the 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, will be 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. The updated guidance also amends the current other-than-temporary impairment model for available for sale debt securities by requiring the recognition of impairments relating to credit losses through an allowance account and limits the amount of credit loss to the difference between a security’s amortized cost basis and its fair value. Subsequent increases or decreases in expected credit losses will be recorded immediately in net earnings through realized gains (losses). AFG will adopt this guidance effective January 1, 2020. The new guidance is not expected to have a material impact on AFG’s results of operations or financial position.
